Abstract
In this paper, the dispersion relations of the surface plasmon polaritons (SPPs) in TI nanowires have been investigated. For simplicity, TI nanowire has been modeled as a dielectric cylinder with a conductive surface, the conductivity of which is an anti-symmetric tensor. The off-diagonal terms of the conductivity tensor only slightly change the dispersion relations. Due to small conductivities, these SPPs have extremely large wavenumbers and azimuthal indices; the electric fields are tightly confined near the conductive surface. For high-order modes, cut-off phenomena have been observed. In the end, the effects of losses and much larger bulk permittivities on the dispersion relations of surface plasmons have been discussed. The simple model proposed in this paper can be directly applied to other materials with arbitrary surface conductivity. Our investigations show that TI nanostructures are promising platforms for nanophotonic applications in the future.

Abstract
Objective: To observe the clinical efficacy of a 3D printed self-stable zero-profile artificial vertebral body for anterior cervical corpectomy decompression and fusion in the treatment of ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. Methods: In this prospective randomized controlled trial, patients diagnosed with OPLL in Luohe Central Hospital from January to July 2022 were divided into a zero-profile group (3D printed self-stable zero-profile artificial vertebral body was used for internal fixation and fusion after anterior cervical subtotal decompression,) and titanium-mesh group (titanium-mesh and titanium plate were used for internal fixation and fusion after anterior cervical subtotal decompression) according to envelope random method. Operation time, intraoperative blood loss, Japanese Orthopaedic Association (JOA) score and improvement rate, incidence of postoperative prosthesis subsidence, and bone graft fusion were recorded and compared between the two groups. Results: Finally, 21 patients in the zero notch group and 20 patients in the titanium mesh group were included in the study and were followed-up. In the zero-profile group, there were 16 males and 5 females, aged (48.0±12.7) years. In the titanium-mesh group, there were 14 males and 6 females, aged (49.8±10.2) years. All the 41 patients successfully completed the operation. In the zero-profile group, the surgical time was (50.04±8.45) minutes, the blood loss was (95.38±26.07) ml and the hospitalization cost was (42.32±6.12) thousand yuan. In the titanium-mesh group, the surgical time was (59.20±11.95) minutes, the blood loss was (93.10±27.86) ml and the hospitalization cost was (42.10±6.71) thousand yuan. The surgical time in the zero-profile group was shorter than that in the titanium-mesh group (P=0.007), and there was no statistically significant difference in blood loss and hospitalization costs between the two groups (both P>0.05). The 41 patients were followed-up for (14.29±1.45) months. Four cases (20.0%) in the titanium mesh group experienced swallowing difficulties and 0 cases in the zero incision group, the difference between the two groups was statistically significant (P=0.048). No intraoperative hematoma, spinal cord nerve recompression, airway crisis, incision infection complications, and no steel plate or screw breakage or displacement occurred after surgery. At the last follow-up, all cases had bone fusion. At the follow-up of 12 months after surgery, the JOA score of the zero incision group increased from preoperative (10.33±1.71) points to (15.47±0.81) points, with an improvement rate of 76.1%±15.7%; the JOA score of the titanium mesh group increased from (10.30±1.75) points to (15.30±0.92) points, with an improvement rate of 73.2%±16.7%; there was no statistically significant difference in improvement rate between the two groups (P=0.580). At the follow-up of 12 months after surgery, 1 case (4.8%) in the zero incision group and 8 cases (40.0%) in the titanium mesh group experienced implant sinking, and the difference between the two groups was statistically significant (P=0.009). Conclusion: Compared with titanium-mesh, 3D printed self-stable zero-profile artificial vertebral body for the treatment of OPLL of the cervical spine can achieve good surgical efficacy, shorter surgical time, lower incidence of postoperative chronic swallowing discomfort, and can provide a better bone material bonding interface and be less prone to prosthesis settlement.

Abstract
Methodologies for training machine learning potentials (MLPs) with quantum-mechanical simulation data have recently seen tremendous progress. Experimental data have a very different character than simulated data, and most MLP training procedures cannot be easily adapted to incorporate both types of data into the training process. We investigate a training procedure based on iterative Boltzmann inversion that produces a pair potential correction to an existing MLP using equilibrium radial distribution function data. By applying these corrections to an MLP for pure aluminum based on density functional theory, we observe that the resulting model largely addresses previous overstructuring in the melt phase. Interestingly, the corrected MLP also exhibits improved performance in predicting experimental diffusion constants, which are not included in the training procedure. The presented method does not require autodifferentiating through a molecular dynamics solver and does not make assumptions about the MLP architecture. Our results suggest a practical framework for incorporating experimental data into machine learning models to improve the accuracy of molecular dynamics simulations.

Abstract
Fecal incontinence is a refractory disease in colorectal surgery. The main clinical manifestation is that patients cannot control the discharge of gas, solid or liquid feces in the rectum autonomously. It is easy to bring shame to patients and seriously affect their physical and mental health. Reducing the frequency of fecal incontinence, restoring anal sphincter function, and improving patient quality of life are important goals for treating fecal incontinence. With the development of medical technology and the improvement of treatment plans for fecal incontinence, patients with fecal incontinence usually undergo conservative treatment first, and if conservative treatment is ineffective, surgery can be chosen. Non-surgical treatment methods commonly used in clinical practice include biofeedback therapy, magnetic stimulation therapy, pelvic floor muscle training, anal sphincter training, Kegel training, and other rehabilitation treatments. This article discusses the non-surgical treatment methods for fecal incontinence, hoping to provide a choice for clinical treatment of fecal incontinence.

Abstract
Objective: To investigate the effects of the application of a low addition refractive multifocal intraocular lens (IOL) using the micromonovision design in the non-dominant eye with different degrees of preset myopia on the visual acuity, visual function and visual quality after bilateral cataract surgery. Methods: In this randomized controlled trial, patients who were proposed to undergo bilateral phacoemulsification combined with rotational asymmetric refractive IOL (MF15 IOL) implantation at the First Affiliated Hospital of Zhengzhou University between September 2020 and August 2022 were included. All patients were divided into three groups using the random number method. The target refraction of the IOL in the dominant eye was 0.00 D. Non-dominant eyes were given different preoperative IOL reserve refractions, with the reserved near additional degree>0.20 D and≤0.40 D as the low addition,>0.40 D and≤0.60 D as the medium addition, and>0.60 D and≤0.80 D as the high addition. We compared uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) of monocular and binocular eyes at 1 day, 1 month and 3 months postoperatively in the 3 groups of patients. Furthermore, the contrast sensitivity, stereopsis, defocus curves and visual quality questionnaire results of binocular eyes were compared at 3 months postoperatively. The statistical methods mainly used were chi-square test, two-factor repeated measures ANOVA, one-way ANOVA, LSD test, Kruskal-Wallis test, and paired t-test. Results: A total of 110 patients (220 eyes) were enrolled in the study, including 48 males and 62 females, with an average age of (59.74±9.38) years. There were 40 patients (80 eyes) in the low additional degree group, 37 patients (74 eyes) in the medium additional degree group, and 33 patients (66 eyes) in the high additional degree group. The differences in distance, intermediate and near visual acuity of the dominant eyes among the three groups were not statistically significant at different measurement timepoints postoperatively (P>0.05). The differences in intermediate and near visual acuity of the non-dominant eyes were also not statistically significant (P>0.05) among the three groups. In contrast, at 3 months, the UDVA of the non-dominant eyes in the low additional degree group (0.04±0.06) and medium additional degree group (0.04±0.07) was significantly higher than that in the high additional degree group (0.08±0.09) (F=4.776, P=0.011, bias η2=0.086). There was no statistically significant difference in binocular uncorrected distance, intermediate and near visual acuity among the three groups at different postoperative timepoints (P>0.05). The binocular UDVA, UIVA and UNVA (logMAR visual acuity) at 3 months postoperatively were -0.04±0.04, 0.03±0.08, 0.10±0.13 in the low addition group, -0.01±0.05, -0.02±0.06, 0.09±0.10 in the medium addition group, and 0.02±0.07, 0.01±0.09, 0.16±0.11 in the high addition group. At 3 months postoperatively, the binocular contrast sensitivity of the low additional degree group was significantly higher than that of the high additional degree group (P<0.05), except that there was no significant difference at the spatial frequency of 6 cycles per degree in the absence of glare (P>0.05). The binocular contrast sensitivity of the medium additional degree group was significantly higher than that of the high additional degree group at the spatial frequencies of 6 and 18 cycles per degree in the glare condition (P<0.05). The difference in the binocular contrast sensitivity between the low and medium additional degree groups did not reach statistical significance (P>0.05). The peak of the binocular defocus curve in the three groups was significantly wider than that in the monocular eyes, and the decline trend was more gentle, with no trough in the middle, and the visual acuity could be maintained above 0.2 (logMAR visual acuity) in the 0.00 D to -3.00 D defocus range. There was no significant difference in the postoperative near stereopsis results among the three groups (P>0.05), with the percentage of near stereopsis sharpness≤60″ reaching 90.00% (36/40), 89.19% (33/37) and 78.79% (26/33), respectively. The proportions of VF-14 scores≥90 in the postoperative questionnaire were 90% (36/40), 91.89% (34/37) and 81.82% (27/33) for the low, medium and high additional degree groups, respectively. The differences in the probability of photic phenomena and spectacles-independent rate were not statistically significant (P>0.05). Conclusion: The use of micromonovision design for bilateral implantation of a rotational asymmetric refractive MF15 IOL, with the non-dominant eye reserved for different near additional degrees, can enable cataract patients to have significantly improved binocular full-range vision, visual function and visual quality. When the degree of reserved near additions in the non-dominant eye preoperatively is>0.20 D and≤0.60 D, it can ensure sufficient binocular UDVA, UIVA and UNVA after surgery, and meanwhile help to obtain superior contrast sensitivity and stereopsis, as well as a satisfactory spectacles-independent rate and low incidence of photic phenomena.

Abstract
Objective: To investigate the utilization of sexual health services among community-based older adults in Chongqing and explore its potential correlates. Methods: A cross-sectional survey using multistage sampling among community-based older adults aged ≥50 years was conducted in Chongqing between June 2020 and December 2022. A questionnaire including information on demographic characteristics, general health, sexual health status, and sexual health services utilization was collected. Sexual health and reproductive services utilization was defined as having ever been tested for human immunodeficiency virus (HIV), or having had a male/gynecological reproductive health examination in the past year. Logistic regression was used to examine the correlates of the utilization of sexual health services. Results: A total of 794 community-based older adults participated in the study (482 were male, and 312 were female). The mean age was (62.8±8.2) years. The proportion of HIV testing was 18.0%, and the proportion of reproductive health examination was 10.1% among community-based older adults. The results of multivariate logistic regression analysis showed that the age group of 60-69 years (aOR=0.37, 95%CI: 0.18-0.76), female (aOR=11.34, 95%CI: 5.71-22.52), monthly income ≥5 000 yuan (aOR=3.05, 95%CI: 1.01-9.27), being sexual activity (aOR=4.99, 95%CI: 2.23-11.15) was significantly associated with had a reproductive health examination in the past year. Conclusions: The proportion of sexual health services utilization among older adults was low. Older sexual health education should be further strengthened, the close relationship between older adults should be correctly guided and dealt with, and the sexual health services suitable for the older population should be formulated.

Abstract
Objective: To investigate the clinical outcome of the coronal Y-shaped osteotomy in the apical vertebra for treating congenital complex rigid scoliosis. Methods: A retrospective analysis was conducted on 66 cases who underwent Y-shaped osteotomy treatment for congenital complex rigid scoliosis in the uppermost vertebra at the Department of Orthopedics,the Second Hospital of Shanxi Medical University from June 2007 to August 2020. There were 19 males and 47 females,with an age of (13.1±5.3) years(range:2 to 30 years).Classification of congenital scoliosis:25 cases (37.9%) were incomplete,13 cases (19.7%) were dysarthritic,and 28 cases (42.4%) were mixed. There were 25 cases (37.9%) with thoracic or rib malformations. 45 cases (68.2%) were complicated with spinal cord malformation.The main radiological indicators included Cobb angle of the curvature,Cobb angle of the local bend,apical vertebral translation (AVT),trunk shift (TS),thoracic trunk shift (TTS),radiographic shoulder height (RSH),coronal balance and sagittal vertebral axis. The preoperative,postoperative immediate,and last follow-up radiological indicators were collected and the operation time,blood loss,hospitalization time,and operation-related complications were recorded. Data were compared by repeated measure ANOVA and paired-t test. Results: All patients underwent surgery successfully. The duration of the first surgery was (221.4±52.8) minutes,and the blood loss during the first surgery was (273.2±41.8) ml. The length of the first hospital stay was (8.8±1.7) days.Unilateral fixation was performed in 19 cases (28.8%),while bilateral fixation was performed in 47 cases (71.2%). The fused segments were 7.5±2.9,and the vertebral pedicle screw density was (68.5±20.6)%. The follow-up time for the 66 patients was (36.7±17.0) months(range:24 to 102 months).The main curve Cobb Angle was improved from (58.5±18.9)°before surgery to (21.1±11.8)°after surgery,and was (23.6±15.3) ° at the last follow-up(F=273.957,P<0.01),with a correction rate of 66.2%. Segmental curve Cobb Angle was improved from (47.9±18.0)° to (16.0±11.3)° after surgery,and was (16.8±12.8) °at the last follow-up (F=270.483,P<0.01)with a correction rate of 69.2%. The AVT,TS,TTS and RSH values improved significantly at the final follow-up (all P<0.05),while coronal balance and sagittal vertical axis were maintained without significant differences between pre-operation and post-operation(both P>0.05). A total of 5 patients underwent staged operation,all of which were residual scoliosis aggravated after the first stage of orthosis operation and had good prognosis after the second stage of operation. Conclusions: Y-shaped osteotomy for the treatment of congenital rigid scoliosis results in good clinical and radiological outcomes without serious complications. This procedure can be considered as an option for the treatment of congenital complex rigid scoliosis.

Abstract
Catalyzed by enormous success in the industrial sector, many research programs have been exploring data-driven, machine learning approaches. Performance can be poor when the model is extrapolated to new regions of chemical space, e.g., new bonding types, new many-body interactions. Another important limitation is the spatial locality assumption in model architecture, and this limitation cannot be overcome with larger or more diverse datasets. The outlined challenges are primarily associated with the lack of electronic structure information in surrogate models such as interatomic potentials. Given the fast development of machine learning and computational chemistry methods, we expect some limitations of surrogate models to be addressed in the near future; nevertheless spatial locality assumption will likely remain a limiting factor for their transferability. Here, we suggest focusing on an equally important effort-design of physics-informed models that leverage the domain knowledge and employ machine learning only as a corrective tool. In the context of material science, we will focus on semi-empirical quantum mechanics, using machine learning to predict corrections to the reduced-order Hamiltonian model parameters. The resulting models are broadly applicable, retain the speed of semiempirical chemistry, and frequently achieve accuracy on par with much more expensive ab initio calculations. These early results indicate that future work, in which machine learning and quantum chemistry methods are developed jointly, may provide the best of all worlds for chemistry applications that demand both high accuracy and high numerical efficiency.

Abstract
Objective: The study investigated the clinical distribution, antimicrobial resistance and epidemiologic characteristics of hypervirulent Carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) in a hospital in Henan Province to provide a scientific basis for antibiotic use and nosocomial infection prevention and control. Methods: A retrospective analysis of the clinical data from the cases was carried out in this study. Clinical data of patients infected with the CRKP strain isolated from the clinical microbiology laboratory of Henan Provincial Hospital of Traditional Chinese Medicine from January 2020 to December 2022 were retrospectively analyzed. A string test, virulence gene screening, serum killing, and a G. mellonella infection model were used to screen hv-CRKP isolates. The clinical characteristics of hv-CRKP and the drug resistance rate of hv-CRKP to twenty-five antibiotics were analyzed using WHONET 5.6. Carbapenemase phenotypic characterization of the hv-CRKP was performed by colloidal gold immunochromatographic assay, and Carbapenemase genotyping, multi-locus sequence typing (MLST) and capsular serotyping of hv-CRKP isolates were performed by PCR and Sanger sequencing. Results: A total of non-duplicate 264 CRKP clinical isolates were detected in the hospital from 2020 to 2022, and 23 hv-CRKP isolates were detected, so the corresponding detection rate of hv-CRKP was 8.71% (23/264). The hv-CRKP isolates in this study were mainly from the intensive care unit (10/23) and neurosurgery department (8/23), and the main sources of hv-CRKP isolates were sputum (10/23) and bronchoalveolar lavage fluid (6/23). The hv-CRKP isolates in this study were highly resistant to β-lactam antibiotics, fluoroquinolones and aminoglycosides, and were only susceptible to colistin, tigecycline and ceftazidime/avibactam. The detection rate of the blaKPC-2 among 23 hv-CRKP isolates was 91.30% (21/23) and none of the class B and class D carbapenemases were detected. Results of MLST and capsular serotypes showed that ST11 type hv-CRKP was the dominant strain in the hospital, accounting for 56.52% (13/23), and K64 (9/13) and KL47 (4/13) were the major capsular serotypes. Conclusion: The hv-CRKP isolates from the hospital are mainly from lower respiratory tract specimens from patients admitted to the intensive care department and the drug resistance is relatively severe. The predominant strains with certain polymorphisms are mainly composed of the KPC-2-producing ST11-K64 and ST11-KL47 hv-CRKP isolates in the hospital.

Abstract
Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Abstract
In recent years, colonic manometry has been gradually introduced into clinical practice. It helps clinicians to gain a better understanding of the physiology and pathophysiology of colonic contractile activity in healthy adults and patients with colonic dysfunction. More and more patterns of colonic motility are being discovered with the help of colonic manometry. However, the clinical significance of these findings still needs to be further investigated. This review enhances our understanding of colonic motility and the current state of development and application of colonic manometry, as well as the limitations, future directions and potential of the technique in assessing the impact of treatment on colonic motility patterns, by analyzing and summarizing the literature related to colonic manometry.

Abstract
Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic pathogenic bacterium with complex pathogenesis and drug resistance mechanisms. It has high morbidity and mortality and can cause acute and chronic infections in immunocompromised individuals, with lung infections, wound infections, and bloodstream infections being the most common. The animal infection model of P. aeruginosa is of great value for in-depth research on the pathogenicity, drug resistance, and therapeutic measures of P. aeruginosa by simulating the pathways of human bacterial infections. This article firstly summarizes the selection, anesthesia, and disposal of experimental animals in the construction of animal models of P. aeruginosa infection, and then reviews the methods of construction, model evaluation, and applications of animal models of P. aeruginosa pulmonary infection, wound infection, and bloodstream infection, in order to provide a reference for scientific research related to P. aeruginosa infectious diseases.

Abstract
Objective: To investigate the association between the urinary arsenic level and serum total testosterone in Chinese men aged 18 to 79 years. Methods: A total of 5 048 male participants aged 18 to 79 years were recruited from the China National Human Biomonitoring (CNHBM) from 2017 to 2018. Questionnaires and physical examinations were used to collect information on demographic characteristics, lifestyle, food intake frequency and health status. Venous blood and urine samples were collected to detect the level of serum total testosterone, urine arsenic and urine creatinine. Participants were divided into three groups (low, middle, and high) based on the tertiles of creatinine-adjusted urine arsenic concentration. Weighted multiple linear regression was fitted to analyze the association of urinary arsenic with serum total testosterone. Results: The weighted average age of 5 048 Chinese men was (46.72±0.40) years. Geometric mean concentration (95%CI) of urinary arsenic, creatinine-adjusted urine arsenic and serum testosterone was 22.46 (20.08, 25.12) μg/L, 19.36 (16.92, 22.15) μg/L and 18.13 (17.42, 18.85) nmol/L, respectively. After controlling for covariates, compared with the low-level urinary arsenic group, the testosterone level of the participants in the middle-level group and the high-level group decreased gradually. The percentile ratio (95%CI) was -5.17% (-13.14%, 3.54%) and -10.33% (-15.68%, -4.63). The subgroup analysis showed that the association between the urinary arsenic level and testosterone level was more obvious in the group with BMI<24 kg/m2 group (Pinteraction<0.05). Conclusion: There is a negative association between the urinary arsenic level and serum total testosterone in Chinese men aged 18-79 years.

Abstract
Objective: To prospectively explore the treatment strategies for clinical difficulties in patients with hyperviremia HBeAg-positive chronic hepatitis B with incomplete response to first-line nucleos(t)ide analogues (NAs). Methods: Patients with hyperviremia HBeAg-positive chronic hepatitis B were treated with first-line NAs, including entecavir, tenofovir disoproxil fumarate (TDF), tenofovir alafenamide fumarate (TAF) for 48 weeks or more. Tenofovir amibufenamide (TMF) or TAF therapy was changed when HBV DNA remained positive and then divided into a TMF group and a TAF group. Clinical efficacy of treatment was evaluated at 24 and 48 weeks, including HBV DNA undetectable rates and virological and serological responses in both patient groups. Results: In the TMF group and the TAF groups, 30 and 26 cases completed 24-week follow-up, while 18 and 12 cases completed 48-week follow-up. There were no statistically significant differences in baseline HBV DNA, HBsAg, and HBeAg levels between the two groups before switching to TMF/TAF therapy (P > 0.05). At 24 weeks of treatment, 19 (19/30, 63.33%) cases in the TMF group had HBV DNA negative conversion, while 14 (14/26, 53.85%) cases in the TAF group had HBV DNA negative conversion (P > 0.05). Among the patients who completed 48 weeks of follow-up, 15 (15/18, 83.33%) cases in the TMF group and 7 (7/12, 58.33%) cases in the TAF group had negative HBV DNA tests (P > 0.05). The changes in HBsAg and HBeAg levels between the two groups of patients at 24 and 48 weeks of treatment were not statistically significant compared to baseline (P > 0.05). Conclusion: TMF is effective in treating patients with hyperviremia HBeAg-positive CHB with an incomplete response to first-line NAs treatment, but there is no significant difference compared to TAF.

Abstract
Machine learning (ML) models, if trained to data sets of high-fidelity quantum simulations, produce accurate and efficient interatomic potentials. Active learning (AL) is a powerful tool to iteratively generate diverse data sets. In this approach, the ML model provides an uncertainty estimate along with its prediction for each new atomic configuration. If the uncertainty estimate passes a certain threshold, then the configuration is included in the data set. Here we develop a strategy to more rapidly discover configurations that meaningfully augment the training data set. The approach, uncertainty-driven dynamics for active learning (UDD-AL), modifies the potential energy surface used in molecular dynamics simulations to favor regions of configuration space for which there is large model uncertainty. The performance of UDD-AL is demonstrated for two AL tasks: sampling the conformational space of glycine and sampling the promotion of proton transfer in acetylacetone. The method is shown to efficiently explore the chemically relevant configuration space, which may be inaccessible using regular dynamical sampling at target temperature conditions.

Abstract
Objective: To evaluate the association of lead exposure with stunting and underweight among children aged 3-5 years in China. Methods: Data was collected from China National Human Biomonitoring (CNHBM) between January 2017 and December 2018. A total of 3 554 children aged 3-5 years were included. Demographic characteristic, lifestyle and nutritional status were collected through questionnaires. Height and weight were measured by standardized method. Stunting and underweight status were determined by calculating height for age Z-score and weight for age Z-score. Blood and urine samples were collected to detect the concentrations of blood lead, urinary lead and urinary creatinine. Children were stratified into 4 groups (Q1 to Q4) by quartiles of blood lead level and corrected urinary lead level, respectively. Complex sampling logistic regression models were applied to evaluate the association of the blood lead level, urinary lead level with stunting and underweight. Results: Among 3 554 children, the age was (4.09±1.06) years, of which 1 779 (80.64%) were female and 1 948 (55.84%) were urban residents. The prevalence of stunting and wasting was 7.34% and 2.96%, respectively. The M (Q1, Q3) for blood lead levels and urinary lead levels in children was 17.49 (12.80, 24.71) μg/L, 1.20 (0.61, 2.14) μg/g Cr, respectively. After adjusting for confounding factors, compared with the lowest blood lead concentration group Q1, the risk of stunting gradually increased in the Q3 and Q4 group (Ptrend=0.010), with OR (95%CI) values of 1.40 (0.80-2.46) and 1.80 (1.07-3.04), respectively. Compared with the lowest urinary lead concentration group Q1, the risk of stunting still increased in the Q3 and Q4 group (Ptrend=0.012), with OR (95%CI) values of 1.69 (1.01-2.84) and 1.79 (1.05-3.06), respectively. The correlation between the lead exposure and underweight was not statistically significant (P>0.05). Conclusion: Lead exposure is positively associated with the risk of stunting among children aged 3-5 years in China.

Abstract
Objective: To investigate the role of inflammatory biomarkers in the relationship between blood lead levels and blood pressure changes. Methods: A total of 9 910 people aged 18-79 years who participated in the China National Human Biomonitoring in 2017-2018 were included in this study. A self-made questionnaire was used to collect demographic characteristics, lifestyle and other information, and the data including height, weight and blood pressure were determined through physical examination. Blood and urinary samples were collected for the detection of blood lead and cadmium levels, urinary arsenic levels, white blood cells, neutrophils, lymphocytes, and hypersensitive C-reactive protein (hs-CRP). Weighted linear regression models were used to evaluate the associations between blood lead, inflammatory biomarkers and blood pressure. Mediation analysis was performed to investigate the role of inflammation in the relationship between blood lead levels and blood pressure changes. Results: The median (Q1, Q3) age of all participants was 45.4 (33.8, 58.4)years, including 4 984 males accounting for 50.3%. Multivariate logistic regression model analysis showed that after adjusting for age, gender, residence area, BMI, education level, smoking and drinking status, family history of hypertension, consumption frequency of rice, vegetables, and red meat, fasting blood glucose, total cholesterol, triglycerides, blood cadmium and urinary arsenic levels, there was a positive association between blood lead levels, inflammatory biomarkers and blood pressure (P<0.05). Each 2.71 μg/L (log-transformed) increase of the lead was associated with a 2.05 (95%CI: 0.58, 3.53) mmHg elevation in systolic blood pressure (SBP), 2.24 (95%CI: 1.34, 3.14) mmHg elevation in diastolic blood pressure (DBP), 0.25 (95%CI: 0.05, 0.46) mg/L elevation in hs-CRP, 0.16 (95%CI: 0.03, 0.29)×109/L elevation in white blood cells, and 0.11 (95%CI: 0.02, 0.21)×109/L elevation in lymphocytes, respectively. Mediation analysis showed that the levels of hs-CRP significantly mediated the association of blood lead with SBP, with a proportion about 3.88% (95%CI: 0.45%, 7.32%). The analysis also found that the levels of hs-CRP and neutrophils significantly mediated the association of blood lead with SBP, with a proportion about 4.10% (95%CI: 1.11%, 7.10%) and 2.42% (95%CI: 0.07%, 4.76%), respectively. Conclusion: This study suggests that inflammatory biomarkers could significantly mediate the association of blood lead levels and blood pressure changes.

Abstract
Objective: To investigate the effect of CD4-positive T lymphocyte expression rate on the pain control and prognosis of stage Ⅳ non-small cell lung cancer (NSCLC) patients with cancerous pain. Methods: The clinical data of 128 stage Ⅳ NSCLC patients with cancerous pain who were admitted to the Affiliated Cancer Hospital of Zhengzhou University from January to December 2020 were retrospectively analyzed, including 92 males and 36 females, with a male-to-female ratio of 23∶9 and an average age of (56±21) years old. The expression rate of CD4-positive T lymphocytes in peripheral blood was routinely detected on admission, and the expression rate of CD4-positive T lymphocytes ≥45% was defined as the CD4 high expression group, and<45% was defined as the low expression group. The differences in the time required for pain control, the dosage of opioids and the incidence of adverse reactions between the two groups were compared and analyzed. Survival analysis was performed by Kaplan-Meier method, and the overall survival (OS) time and progression-free survival (PFS) time of the two groups were calculated. Cox regression model was used to analyze the influencing factors of patients' OS time and PFS time. Results: The median time required for pain control in the high CD4 expression group [M (Q1, Q3)] was 18.6 (4.6, 21.5) h, which was lower than that in the low CD4 expression group [28.2 (7.1, 38.9) h] (P=0.012). The dosage of morphine in the CD4 high expression group [M (Q1, Q3)] was 88.6 (42.5, 295.0) mg, which was lower than that in the low expression group [145.8 (82.5, 442.5) mg] (P=0.010). There was no significant difference in the incidence of adverse reactions such as nausea and vomiting, constipation, urinary retention, intestinal obstruction, and respiratory depression between the two groups (all P>0.05). The OS time and PFS time in the CD4 high expression group [M (Q1, Q3)] were 12.5 (8.1, 13.8) months and 8.5(3.1, 9.4) months, respectively, which were higher than those in the CD4 low expression group [8.6 (4.1, 12.9) months and 6.5 (2.1, 7.9) months, respectively] (all P<0.01). Cox multivariate analysis showed that high expression of CD4 was a protective factor affecting OS (HR=0.876, 95%CI: 1.224-6.641, P=0.004) and PFS (HR=0.675, 95%CI: 1.742-5.930, P=0.031) Conclusion: The stage Ⅳ NSCLC patients with cancerous pain and high expression of CD4-positive T lymphocytes have shorter pain control time, less morphine dosage, and longer OS and PFS time.

Abstract
Machine learning (ML) is becoming a method of choice for modelling complex chemical processes and materials. ML provides a surrogate model trained on a reference dataset that can be used to establish a relationship between a molecular structure and its chemical properties. This Review highlights developments in the use of ML to evaluate chemical properties such as partial atomic charges, dipole moments, spin and electron densities, and chemical bonding, as well as to obtain a reduced quantum-mechanical description. We overview several modern neural network architectures, their predictive capabilities, generality and transferability, and illustrate their applicability to various chemical properties. We emphasize that learned molecular representations resemble quantum-mechanical analogues, demonstrating the ability of the models to capture the underlying physics. We also discuss how ML models can describe non-local quantum effects. Finally, we conclude by compiling a list of available ML toolboxes, summarizing the unresolved challenges and presenting an outlook for future development. The observed trends demonstrate that this field is evolving towards physics-based models augmented by ML, which is accompanied by the development of new methods and the rapid growth of user-friendly ML frameworks for chemistry.

Abstract
Objective: To analyze the characteristics of pulse-step-sine (PSS) test in healthy people of different ages and to discuss its clinical value. Methods: From July 10, 2018 to December 9, 2020, a total of 78 healthy volunteers, including 40 males and 38 females, were enrolled and divided into youth group, middle age group and old age group. The I Portal NOTC rotational-chair system (NKI) was applied for PSS detection to analyze the clinical characteristics of gain, phase, asymmetry, and slope of step and sinusoidal components. Statistical analysis was performed using SPSS17.0 software. Results: In the same age group, there were no statistically significant differences in left and right step gain, slope gain and sine gain (All P values were greater than 0.05). Pairwise comparison between different age groups showed that there was no significant difference in the corresponding parameters between the youth group and the middle age group. Compared with young group, the old age group had a significantly lower step gain value in their left side (P<0.01) but not in the right side (P>0.05).The left and right slopes of the old age group were significantly lower than those of the young group and the middle group, and the differences were statistically significant (All P values<0.05). Conclusion: The PSS test can detect bilateral and unilateral horizontal semicircular canal function with good tolerance in different age groups, better than the traditional rotational chair examination to determine the well-compensated unilateral vestibular function. PSS test is a new vestibular detection method.

Abstract
Objective: The characteristics of 3D-FLAIR MRI images of the inner ear of patients with vestibular neuritis were preliminarily studied to explore the possible pathogenesis of vestibular neuritis, and the correlation analysis was conducted in combination with vestibular function to provide a basis for accurate diagnosis of vestibular neuritis. Methods: A total of 36 patients with vestibular neuritis (VN) from December 2019 to October 2020 were collected from the Vertigo Department of Shandong Provincial ENT Hospital, Cheeloo College of Medicine, Shandong University. There were 36 cases (18 females, 18 males) with unilateral acute vestibular neuritis, 17 cases of left ear and 19 cases of right ear. According to the results of 3D-FLAIR MRI in the inner ears, the patients were divided into the enhanced group and the non-enhanced group (the health side served as the normal control group). The results of vestibular function examination in the two groups were compared. SPSS19.0 software was used for statistical processing to analyze the relationship between the vestibular function and the characteristics of 3D-FLAIR imaging in the inner ears. Results: Abnormal enhancement of 3D-FLAIR was found in 31 cases (86.1%) of the 36 cases, including 14 cases of both vestibular nerve and vestibular terminal organ enhancement, eight cases of superior vestibular nerve enhancement alone, seven cases of vestibular terminal organ enhancement alone, and two cases of cochlear enhancement alone. Observation of abnormal reinforcement of vestibular nerve showed: twenty-one cases of superior vestibular nerve reinforcement, one case of superior and inferior vestibular nerve reinforcement. No abnormalities were found in 3D-FLAIR of inner ear in 5 cases. According to the analysis of vestibular function results, there were 19 cases (52.8%) with total vestibular involvement, sixteen cases (44.4%) with superior vestibular involvement alone, and one case (2.8%) with inferior vestibular involvement alone. Comparison of vestibular function between the five cases (non-enhancement group) and the 31 cases (enhanced group) in the 3D-FLAIR group of the inner ears showed that the CP values of caloric tests in the enhanced group were higher (60.81±3.49 vs 34.12±7.37), with statistically significant difference (t=-2.898, P<0.01). Conclusion: In patients with vestibular neuritis, 3D-FLAIR MRI scan of the inner ear provides visual imaging evidence for clinical practice, considering that the lesion site of vestibular neuritis is not only in the vestibular nerve, but also in the vestibular end organ. Patients with 3D-FLAIR enhanced in the inner ear may have more significant vestibular function damage.

Abstract
Using a realistic molecular catalyst system, we conduct scaling studies of ab initio molecular dynamics simulations using the popular CP2K code on both Intel Xeon CPU and NVIDIA V100 GPU architectures. Additional performance improvements were gained by finding more optimal process placement and affinity settings. Statistical methods were employed to understand performance changes in spite of the variability in runtime for each molecular dynamics timestep. Ideal conditions for CPU runs were found when running at least four MPI ranks per node, bound evenly across each socket. This study also showed that fully utilizing processing cores, with one OpenMP thread per core, performed better than when reserving cores for the system. The CPU-only simulations scaled at 70% or more of the ideal scaling up to 10 compute nodes, after which the returns began to diminish more quickly. Simulations on a single 40-core node with two NVIDIA V100 GPUs for acceleration achieved over 3.7× speedup compared to the fastest single 36-core node CPU-only version. These same GPU runs showed a 13% speedup over the fastest time achieved across five CPU-only nodes.

Abstract
Objective: To investigate the diagnostic value of long noncoding RNA (lncRNA) extracted from serum exosomes in epithelial ovarian cancer (EOC). Methods: (1) Patients with ovarian tumors who were hospitalized in the Affiliated Tumor Hospital of Guangxi Medical University from August 2018 to December 2019, including 35 cases of EOC patients (malignant group) and 20 cases of benign ovarian tumor patients (benign group) were collected; during the same period, 15 healthy women (normal group) who underwent physical examination in the Affiliated Tumor Hospital of Guangxi Medical University were used as controls. Fasting venous blood serum was collected from the above three groups of women, and serum exosomes were isolated and purified using commercial kits. The morphology of exosomal particles was observed with transmission electron microscope, and the particle size distribution of the exosomes was detected by NanoSight technology. The expression of specific proteins cluster of differentiation (CD)63, CD81, and tumor susceptibility gene 101 (TSG101) of exosomes were analyzed by western blot. (2) Four cases of EOC patients and three cases of healthy women were randomly selected. High-throughput sequencing technology was used to analyze the differentially expressed lncRNA in serum exosomes of these four EOC patients and three healthy women, and screen out the significantly differentially expressed lncRNA. The screened lncRNA with different expression levels was verified by quantitative reverse transcription-polymerase chain reaction (QRT-PCR) in these seven original clinical samples, furtherly confirmed and tested with QRT-PCR in larger clinical samples (a total of 70 serum samples). (3) The receiver operating characteristic (ROC) curve of the target lncRNA was drawn and its diagnostic indicators such as sensitivity and specificity were evaluated. By using logistic binary regression model, multi-factor joint diagnostic models were constructed and evaluated. Results: (1) Under transmission electron microscope, clear lipid bilayer structure was observed in serum exosomes, and one side presented a concave hemispheric or cup like structure; the peak diameter of the exosomal particles detected with NanoSight technology was 127.6 nm, and the particles between 30 and 150 nm accounted for 58.9%; western blot confirmed that the obtained (exosomal) particles could detect the expression of the marker proteins CD63, CD81, and TSG101. (2) Analysis of high-throughput sequencing technology showed that compared with the women in the normal sequencing group (3 cases), 425 differentially expressed lncRNAs (including 23 up-regulated and 402 down-regulated) were screened in the serum exosomes of the malignant sequencing group (4 cases). Six types of lncRNA with significantly abnormal expression levels (including FER1L6-AS2, LINC00470, LINC01811, CXXC4-AS1, LINC02343, and LINC02428) were randomly selected for original sample verification, and the results were consistent with the sequencing results. Subsequently, these six lncRNAs were used for larger samples QRT-PCR verification. Compared with the benign and normal groups, the expression of FER1L6-AS2, LINC00470 and LINC01811 in malignant group increased by 1.66 and 1.84-fold, 2.05 and 2.46-fold, 2.94 and 2.35-fold, respectively; the expressions of CXXC4-AS1, LINC02343 and LINC02428 were down-regulated to 29% and 34%, 40% and 46%, 42% and 42%, respectively. For the same lncRNA, there were statistical differences between the malignant group and the benign group, between the malignant group and the normal group (all P<0.05), and there were no statistical differences between the benign group and the normal group (all P>0.05). (3) The results showed that the area under curve (AUC) of these six lncRNAs ranged from 0.722 to 0.805, which had moderate diagnostic efficiency. To use logistic binary regression model to establish multi-indicator joint diagnostic models and establish different joint factor ROC curves. The results showed that the AUC of the joint factor prediction model 1 (composed of FER1L6-AS2 and LINC01811), the joint factor prediction model 2 (composed of CXXC4-AS1, LINC02343, and LINC02428), and the joint factor prediction model 3 (composed of FER1L6-AS2, CXXC4-AS1, LINC02343, and LINC02428) were 0.865, 0.934, and 0.962, respectively. The diagnostic efficacy of the combined factor prediction models was higher than that of the single lncRNA (all P<0.05). Conclusions: High-throughput sequencing technology is an effective method for screening out the different expression levels of lncRNA extracted from serum exosomes. The combined detection of multiple serum exosomal lncRNA indicators has a certain diagnostic efficacy for patients with EOC. Detection of serum exosomal lncRNA indicators will provide new ideas for the diagnosis of EOC.

Abstract
We identify configurational phases and structural transitions in a polymer nanotube composite by means of machine learning. We employ various unsupervised dimensionality reduction methods, conventional neural networks, as well as the confusion method, an unsupervised neural-network-based approach. We find neural networks are able to reliably recognize all configurational phases that have been found previously in experiment and simulation. Furthermore, we locate the boundaries between configurational phases in a way that removes human intuition or bias. This could be done before only by relying on preconceived, ad hoc order parameters.

Abstract
Objective: To investigate the association of blood lead and blood selenium with serum high-sensitivity C-reactive protein (hs-CRP) among Chinese adults aged 19 to 79 years. Methods: The participants were enrolled from the first wave of China National Human Biomonitoring (CNHBM) conducted from 2017 to 2018. 10 153 participants aged 19 to 79 years were included in this study. Fasting blood samples were obtained from participants. Lead and selenium in whole blood and hs-CRP in serum were measured. Individuals with hs-CRP levels above 3.0 mg/L were defined as elevated hs-CRP. Generalized linear mixed models and restricted cubic spline models were used to analyze the association of blood lead and blood selenium with elevated hs-CRP. Logistic regression models were used to analyze the multiplicative scale and additive scale interaction between blood lead and blood selenium on elevated hs-CRP. Results: The age of participants was (48.91±15.38) years, of which 5 054 (61.47%) were male. 1 181 (11.29%) participants were defined as elevated hs-CRP. After multivariable adjustment, results from generalized linear models showed that compared with participants with the lowest quartile of blood lead, the OR (95%CI) of elevated hs-CRP for participants with the second, third, and highest quartiles were 1.14 (0.94-1.37), 1.25 (1.04-1.52) and 1.38 (1.13-1.68), respectively. When compared with participants with the lowest quartile of blood selenium, the OR (95%CI) of elevated hs-CRP for participants with the second, third and highest quartiles were 0.86 (0.72-1.04), 0.91 (0.76-1.11), and 0.75 (0.61-0.92), respectively. Results from the interaction analysis showed no significant interaction between lead and selenium on elevated hs-CRP. Conclusion: Blood concentration of lead was positively associated with elevated serum hs-CRP, and blood concentration of selenium was inversely related to elevated hs-CRP, while blood lead and selenium did not present interaction on elevated hs-CRP.

Abstract
Objective: To investigate the association between urinary arsenic levels and anemia among older adults in nine longevity areas of China. Methods: A total of 1 896 subjects aged 65 years and above who participated in the Healthy Aging and Biomarkers Cohort Study (HABCS) in 2017-2018 were included. A self-made questionnaire was used to collect demographic characteristics, lifestyle and other information from the subjects. Through physical examination, data including height, weight and blood pressure were determined and body mass index (BMI) was calculated. Blood and urine samples were collected for the detection of hemoglobin (Hb), blood glucose, blood lipids, plasma vitamin B12 and urinary arsenic concentrations. The urinary arsenic levels were divided into four groups according to the quartiles of urinary arsenic concentrations (μg/g creatinine): Q1 (<18.7), Q2 (18.7-34.5), Q3 (34.6-69.5) and Q4(≥69.6). Multivariate logistic regression model and restricted cubic spline fitting logistic regression model were used to analyze the association between urinary arsenic levels and anemia. Results: The age of the 1 896 subjects (M (Q1, Q3)) was 83 (74, 92) years, including 952 females (50.21%), and the concentration of Hb (M (Q1, Q3)) was 135 (124, 147)g/L. The prevalence of anemia was 24.89% (472 cases). The geometric mean and M (Q1, Q3) of urinary arsenic concentrations were 37.5 and 34.6 (18.7, 69.6)μg/g creatinine, respectively. Multivariate logistic regression model analysis showed that after adjusting for age, gender, BMI, education level, smoking and drinking status, residence, economic level, ethnicity, the status of vitamin B12 deficiency, consumption frequency of aquatic products and meat, the prevalence of hypertension, diabetes and dyslipidemia, urinary arsenic levels were positively associated with anemia (Taking group Q1 as a reference, OR (95%CI) values in Q2, Q3 and Q4 groups were 1.73 (1.20-2.50), 2.08 (1.43-3.02) and 1.52 (1.02-2.28), respectively). The results of restricted cubic spline fitting logistic regression analysis showed a non-linear association between urinary arsenic concentrations and anemia (P<0.001). Subgroup analysis showed there was a negative multiplicative interaction between the prevalence of chronic diseases and urinary arsenic levels with OR (95%CI) was 0.55 (0.30-0.99), while no multiplicative interaction was found between age, gender, residence, smoking status, drinking status and urinary arsenic levels (P>0.05). There was a positive association between urinary arsenic levels and anemia in participants who were absence of chronic diseases,male, living in rural, smoking and drinking with OR (95%CI) values of 3.62 (1.30-10.06),2.46 (1.34-4.52), 1.70 (1.03-2.80), 2.21 (1.01-4.82) and 2.79 (1.23-6.33), respectively. Conclusion: There is a positive association between urinary arsenic levels and anemia among older adults in nine longevity areas of China.

Abstract
Hypervirulent Klebsiella pneumoniae, short for hvKP, is a hypervirulent variant of classical Klebsiella pneumoniae, which accounts for serious infection in healthy people, exhibits strong pathogenicity, high mortality and poor prognosis. At present, hvkp is of high prevalence all over the world, and the infection rate shows a continuous upward trend, which brings great challenges to public health security and clinical treatment. This paper summarized the research progress on virulence factors of hvkp, such as capsular polysaccharides, siderophore, lipopolysaccharide, adhesins and recently discovered Type Ⅵ secreting system, and aimed to deepen the understanding and recognition of hvKP.

Abstract
(Quasi-)one-dimensional systems exhibit various fascinating properties such as Luttinger liquid behavior, Peierls transition, novel topological phases, and the accommodation of unique quasiparticles (e.g., spinon, holon, and soliton, etc.). Here we study molybdenum blue bronze A0.3MoO3 (A = K, Rb), a canonical quasi-one-dimensional charge-density-wave material, using laser-based angle-resolved photoemission spectroscopy. Our experiment suggests that the normal phase of A0.3MoO3 is a prototypical Luttinger liquid, from which the charge-density-wave emerges with decreasing temperature. Prominently, we observe strong renormalizations of band dispersions, which are recognized as the spectral function of Holstein polaron derived from band-selective electron-phonon coupling in the system. We argue that the strong electron-phonon coupling plays an important role in electronic properties and the charge-density-wave transition in blue bronzes. Our results not only reconcile the long-standing heavy debates on the electronic properties of blue bronzes but also provide a rare platform to study interesting excitations in Luttinger liquid materials.

Abstract
Objective: To analyze, explore and evaluate the clinical characteristics, abnormal thyroid function and follow-up of anti-hyperthyroidism treatment mode in patients with hyperthyroidism (commonly abbreviated as HT) combined with liver injury. Methods: The clinical data of patients with hyperthyroidism combined with liver injury were retrospectively analyzed, and then patients were divided into treated and untreated group according to whether they received anti-hyperthyroidism treatment before the consultation. Patients' thyroid and liver function test indicators at the time of treatment were analyzed to determine the main cause of liver injury. The characteristics of liver injury were analyzed in the treatment group. Patients with severe thyroid toxicity and hyperthyroidism combined with liver injury were followed-up with anti-hyperthyroid therapy, mainly low-dose methimazole (MMI) and radioactive iodine therapy to evaluate its efficacy and safety. The comparison between data groups was performed by t-test, rank sum test and χ( 2) test. Results: Among the 43 cases with hyperthyroidism combined with liver injury, 19 were males and 24 were females, aged 49.0 ± 14.6 years-old; 16 cases (16/43, 37.21%) aged 40 to≤60 years- old, and 15 cases (15/43, 34.88%) aged > 60 years-old. There were 22 untreated cases (untreated group, accounting for 51.16%), and 21 treated cases with anti-hyperthyroidism (treatment group, accounting for 48.84%) at the time of consultation. Thyroid function indicators (FT3, FT4, TSH) and liver function indicators (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, γ-glutamyltransferase, total bilirubin) of the two groups were compared, and the difference was not statistically significant (P > 0.05). The order of liver injury from mild to severe in patients with different treatment options were: methimazole (MMI) < propylthiouracil < radioactive iodine <traditional Chinese herbal medicine. Low-dose MMI was safe and effective in patients with different degrees of liver injury with anti-hyperthyroidism treatment. Conclusion: The incidence of hyperthyroidism combined with liver injury is age-related, mainly due to thyroid toxicity. Low-dose MMI is safe and effective in patients with different degrees of liver injury with anti-hyperthyroidism treatment.

Abstract
Machine learning (ML) is quickly becoming a premier tool for modeling chemical processes and materials. ML-based force fields, trained on large data sets of high-quality electron structure calculations, are particularly attractive due their unique combination of computational efficiency and physical accuracy. This Perspective summarizes some recent advances in the development of neural network-based interatomic potentials. Designing high-quality training data sets is crucial to overall model accuracy. One strategy is active learning, in which new data are automatically collected for atomic configurations that produce large ML uncertainties. Another strategy is to use the highest levels of quantum theory possible. Transfer learning allows training to a data set of mixed fidelity. A model initially trained to a large data set of density functional theory calculations can be significantly improved by retraining to a relatively small data set of expensive coupled cluster theory calculations. These advances are exemplified by applications to molecules and materials.

Abstract
Objective: To analyze the association of the cadmium internal exposure with chronic kidney disease (CKD) in Chinese adults aged 18 and older. Methods: A total of 9 821 adults aged 18-79 from the China National Human Biomonitoring (CNHBM) from 2017 to 2018 were included. Blood and urine cadmium exposure levels were measured by inductively coupled plasma mass spectrometry (ICP-MS), and urine cadmium levels were adjusted with urine creatinine; CKD were defined by estimated glomerular filtration (eGFR) using the chronic kidney disease epidemiology collaboration (CKD-EPI). Weights were considered due to complex sampling process for in statistical analysis. Logistic regression is used to analyze the association of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine exposure levels with CKD, and restricted cube spline (RCS) was used to assess the exposure-response curve of blood cadmium, urine cadmium and urine cadmium adjusted with creatinine with CKD. Results: The weighted age was 44.75 and males accounted for 61.1%. The prevalence rate of CKD was 12.7%. The geometric mean values of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine were 0.96 μg/L, 0.61 μg/L, and 0.58 μg/g. After adjusting for confounding factors, the weighted logistic regression showed that the lowest quintile (Q1) was compared with the odds ratio (OR) of the highest quintile (Q5) of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine and the 95% confidence interval (CI) was 1.80 (1.02-3.20), 1.77 (0.94-3.31) and 1.94 (1.11-3.37) respectively. In the restricted cubic spline regression model, non-linear association of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine with CKD were observed after adjusting for related confounding factors (P<0.001, 0.018, 0.031 respectively). The risk of CKD increased with the increment of cadmium exposure without risk threshold, and the exposure response curve was steeper at low cadmium exposure. Conclusions: Among Chinese adults aged 18 and older, cadmium exposure is positively associated with the risk of chronic kidney disease.

Abstract
Objective: To analyze the clinical characteristics of congenital agammaglobulinemia and the efficacy of intravenous immunoglobulin (IVIG) replacement therapy for this disease. Methods: The basic characteristics, clinical manifestations, laboratory examinations, and outcomes of 114 patients with congenital agammaglobulinemia diagnosed in Children's Hospital of Chongqing Medical University from January 1988 to April 2020 were retrospectively analyzed. The efficacy of IVIG in improving the clinical symptoms between regular and irregular treatment groups were compared by χ2 test. To explore the clinical characteristics associated with delayed diagnosis and treatment, the patients were also stratified into following subgroups: non-cough, short-term cough and long-term cough groups, chronic lung disease and non-chronic lung disease groups, and arthritis and non-arthritis groups. The age at onset, age at diagnosis, time consumed for diagnosis, initial time of immunoglobulin replacement, dose of IVIG, IgG trough level between the above groups were compared by t test, F test or non-parametric test. Results: All the 114 patients were male, with the onset age of (22±18) months. The age at diagnosis was (89±54) months, time consumed in diagnosis was (63±46) months, and the initial time of immunoglobulin replacement was (75±45) months. A total of 66 patients had been followed up to April 2020, with a follow-up period of (54±41) months. Among these children, 42 (63.6%) received regular infusion, whose monthly IVIG dose was (538±105) mg/kg and IgG trough level was (5.8±1.5) g/L, whereas 24 patients (36.4%) were treated irregularly. There was no significant difference in the improvement rate of fever, cough, sinusitis, diarrhea, otitis media and arthritis between regular and irregular IVIG replacement groups (all P>0.05). Sixty-one out of the 66 patients (92.4%) had fever before IVIG treatment, whose fever episodes were significantly decreased after IVIG treatment (5 (2,12) vs. 0 (0, 1) per year, Z =-6.436, P<0.01). Sixty patients (90.9%) suffered from wet cough before treatment and 36 (54.5%) after treatment. Initial time of immunoglobulin replacement was significantly delayed in the long-term cough (27 cases) and short-term cough groups (9 cases) compared with non-cough group (18 cases) ((97±51) vs. (64±41) vs. (63±42) months, F=3.554, P=0.035). Twenty-nine patients (43.9%) were diagnosed with chronic lung disease, whose initial time of immunoglobulin replacement (103 (75,144) vs. 46 (26,64) months, Z=-4.330, P<0.01), age at diagnosis (103 (75,142) vs. 47 (31,68) months, Z=-3.486, P<0.01), and time consumed in diagnosis (91 (55,129) vs. 29 (10,41) months, Z =-4.386, P<0.01) were significantly later and longer than those in children without chronic lung disease (37 cases). In addition, thirty-two patients(48.5%) were diagnosed with arthritis, whose initial time of immunoglobulin replacement ((98±51) vs. (58±39) months,t=3.420, P=0.001) and time consumed in diagnosis ((74±49) vs. (44±40) months, t=2.600, P=0.010) were also significantly later and longer than those in children without arthritis (34 cases). Conclusions: After immunoglobulin replacement therapy, the clinical symptoms such as fever, sinusitis, diarrhea, and otitis media can be improved more or less. However, long-term wet cough, chronic lung disease, and arthritis are still prominent clinical problems, which could be controlled by standard immunoglobulin replacement therapy in some patients.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by coughing, the production of excess sputum, and dyspnea. Patients with excessively thick sputum may have frequent attacks or develop more serious disease. The guidelines recommend airway clearance for patients with excessive sputum who are hospitalized with COPD. The active cycle of breathing technique is the most common non-pharmacological airway clearance technique used by physiotherapists. However, the effectiveness of the technique is not always guaranteed. Active cycle of breathing techniques require the initial dilution of the sputum, usually by inhalation drugs, which may have limited effects. Recent studies have found that phonophoresis decreases inflammation, suggesting the potential of the combined usage of active cycle of breathing techniques and phonophoresis. Therefore, the aim of this study is to explore the effectiveness and safety of combining active cycle of breathing technique and phonophoresis in treating COPD patients. Methods and analysis We propose a single-blind randomized controlled trial using 75 hospitalized patients diagnosed with COPD with excessive sputum production. The patients will be divided into three groups. The intervention group will receive active cycle of breathing techniques combined with phonophoresis. The two comparison groups will be treated with active cycle of breathing techniques and phonophoresis, respectively. The program will be implemented daily for 1 week. The primary outcomes will be changes in sputum viscosity and production, lung function, and pulse oximetry. Secondary outcomes include the assessment of COPD and anxiety, measured by the COPD Assessment Test scale and the Anxiety Inventory for Respiratory Disease, respectively; self-satisfaction; the degree of cooperation; and the length of hospital stay. All outcome measures, with the exception of sputum production and additional secondary outcomes, will be assessed at the commencement of the study and after 1 week’s intervention. Analysis of variance will be used to investigate differences between the groups, and a p-value of less than 0.05 (two-tailed) will be considered statistically significant. Discussion This study introduces a combination of active cycle of breathing techniques and phonophoresis to explore the impact of these interventions on patients hospitalized with COPD. If this combined intervention is shown to be effective, it may prove to be a better treatment for patients with COPD. Trial registration The trial was registered prospectively on the Chinese Clinical Trial Registry on 24 December 2019.ClinicalTrials.gov ChiCTR1900028506. Registered on December 2019.

Abstract
Objective: To explore the clinical effect of lumbar discectomy and nerve root canal's enlargement preserving the continuity of supraspinous ligament in the treatment of lumbar degenerative disease. Methods: The data of patients with lumbar degenerative disease who underwent operation from 2016 to 2018 were analyzed retrospectively, and the patients were divided into two groups according to the different operation. The treatment group (17 cases) was treated with recapping laminoplasty, lumbar discectomy and nerve root canal's enlargement, and the control group (28 cases) was treated with total laminectomy, nerve root canal's enlargement, lumbar discectomy, interbody fusion and internal fixation (PLIF). All patients were followed up for 12 to 27 months (mean 17.8 months). Japanese Orthopaedic Association Scores(JOA) and visual analogue scale(VAS) of pain were used to evaluate the clinical effect before and after the operation, lumbar dynamical X-ray and Cobb angle were collecting for imaging evaluation, and the adjacent segment degeneration at the last follow-up was recorded. Results: There was no significant difference in preoperative JOA score, VAS score and Lumbar Cobb angle between the two groups (all P>0.05). The operation time in the treatment group was shorter than that in the control group, and the blood loss during operation in the treatment group was lower than that in the control group, the bed rest time of the treatment group after operation was shorter than that in the control group ((79±14) vs (118±17) min, (151±38) vs (324±70) ml and (3.4±0.7) vs (4.3±1.0) d,respectively; t=-8.508, -10.724, -3.244, all P<0.01). In addition, compared with the control group, the volume of postoperative drainage in the treatment group also decreased significantly (t=-5.637, P<0.01). There was no significant difference in JOA score between the two groups 1 year after the operation (P>0.05), but there was significant difference in VAS score between the two groups, the treatment group was better than the control group (P<0.05). Compared with the control group, the lumbar Cobb angle in the treatment group increased significantly one year after the operation (55.3°±3.2° vs 38.4°±6.2°, t=10.391, P<0.05). During the follow-up, no loosening or fracture of the implants was found in all patients. Conclusion: Treatment of lumbar degenerative diseases with recapping laminoplasty and nerve root canal's decompression preserving the continuity of supraspinous ligament by ultrasound osteotome has the same clinical effect as PLIF. It has the advantages of shortening operation time, less bleeding, better maintenance of lumbar lordosis after operation and reduction of adjacent segment degeneration.

Abstract
We present a novel deep learning (DL) approach to produce highly accurate predictions of macroscopic physical properties of solid solution binary alloys and magnetic systems. The major idea is to make use of the correlations between different physical properties in alloy systems to improve the prediction accuracy of neural network (NN) models. We use multitasking NN models to simultaneously predict the total energy, charge density and magnetic moment. These physical properties mutually serve as constraints during the training of the multitasking NN, resulting in more reliable DL models because multiple physics properties are correctly learned by a single model. Two binary alloys, copper-gold (CuAu) and iron-platinum (FePt), were studied. Our results show that once the multitasking NN's are trained, they can estimate the material properties for a specific configuration hundreds of times faster than first-principles density functional theory calculations while retaining comparable accuracy. We used a simple measure based on the root-mean-squared errors to quantify the quality of the NN models, and found that the inclusion of charge density and magnetic moment as physical constraints leads to more stable models that exhibit improved accuracy and reduced uncertainty for the energy predictions.

Abstract
BACKGROUND While active cycle of breathing technique for chronic obstructive pulmonary disease patients with more sputum can improve clinic outcomes, less is known about sputum viscosity and sputum production of the intervention. OBJECTIVE The purpose of our study was to explore the effect of active cycle of breathing technique on sputum viscosity and production among patients with chronic obstructive pulmonary disease. DESIGN This was a two-arms, parallel, randomized clinical trial. SETTING Study enrollment, randomization and implementation were conducted in the department of respiratory medicine inpatient at the Medical Center in Changchun, China. PARTICIPANTS Hospitalized patients due to chronic obstructive pulmonary disease who met additional eligibility criteria were randomized to active cycle of breathing technique (n = 50) or usual care group (n = 50). METHODS Patients in the intervention group received a week-long intervention from an experienced physical therapist. Patients in the usual care group received usual care as well as information and advice in the light of their health plan from respiratory medicine. The primary outcome was the changes on sputum viscosity and production. RESULTS Among one hundred patients who were randomized (mean [SD] age, 54.89 [12.06] years; females, 58%), ninety-six participants completed the study. No significant differences were found between two groups on the changes of sputum viscosity (t = 0.277, P = 0.782). And there were insignificant differences between groups in the average amount of sputum among 1 h (Z=-1.848, P = 0.065) and significant differences in the average amount of sputum among 24 h (Z=-2.236, P = 0.025). From admission to one week recovery, the changes in ratio of forced expiratory volume in 1 s to forced vital capacity (Z=-4.511, P<0.0001) and arterial oxygen saturation (Z=-2.997, P = 0.003) were better in active cycle breathing technique group. Total Chronic Obstructive Pulmonary Disease Assessment Test scale were similar among two groups (Z=-1.818, P = 0.069). No adverse events occurred during the study. CONCLUSION For patients with chronic obstructive pulmonary disease, active cycle of breathing technique can significantly result in sputum production and respiratory function, especially those of Global Initiative for Chronic Obstructive Lung Disease classification level 3, but did not result in the short-term improvement of sputum viscosity, quality of life and cost effectiveness.

Abstract
Objective: The study is to examine association of sleep duration and cognitive impairment in the older adults aged 65 years and older in China. Methods: We analyzed data from 2017-2018 wave of Chinese Longitudinal Healthy Longevity Survey (CLHLS). A total of 14 966 participants were included in the analysis. Data with respect to socioeconomic status, community involvement, behavior pattern, diet, life style, family structure, disease condition, mental health and cognitive function were collected. Cognitive function was measured with Mini-mental State Examination (MMSE). We conducted generalized linear mixed models to examine associations of sleep duration with cognitive impairment, and subgroup analyses of sex and age were conducted. Results: Among 14 966 participants, the percentage of participants aged 65 to 79 years, 80 to 89 years, 90 to 99 years and 100 years and older was 5 148 (4.40%), 3 777 (25.24%), 3 322 (22.20%) and 2 719 (18.16%), respectively. A total of 2 704 participants reported sleep duration of 5 h and less, and 3 883 reported 9 h and more, accounting for 18.94% and 27.19%, respectively. In total, 3 748 were defined with cognitive impairment, accounting for 25.04%. The results of generalized linear mixed models showed that both short (≤5 h) and long (≥ 9 h) sleep duration were associated with cognitive impairment compared with sleep duration of 7 h, with OR(95%CI) of 1.35(1.09-1.68) and 1.70(1.39-2.07), respectively. The association of sleep duration with cognitive impairment was more obvious in males and individuals aged 65 to 79 years old. Conclusion: Short or long sleep duration was responsible for increased risk of cognitive impairment in older Chinese.

Abstract
Pseudomonas aeruginosa is one of the common multidrug-resistant bacteria in the clinic. Because it can produce a "protective" biofilm, it can affect the penetration and killing efficacy of antibacterial drugs, leading to the formation of a persistent and persistent chronic infection in the host. Biofilms make Pseudomonas aeruginosa resistant to antibacterials and evasive to the host's immune system. Therefore, traditional conventional antibacterials are difficult to achieve effective bactericidal treatment. Understanding the process of P. aeruginosa biofilm formation and the regulatory mechanisms that affect biofilms can provide ideas and methods for our future research on new antibacterial drugs.

Abstract
Objective: Aldo-keto reductase family 1 member B10 (AKR1B10) pathogenesis, early diagnosis and prognosis are closely related with hepatoma. Therefore, this study explores the effect and mechanism of AKR1B10 on cell cycle in hepatoma cells. Methods: HepG2 cells were infected with lentivirus LV-AKR1B10-shRNA or treated with epalrestat, an AKR1B10 inhibitor. The expression level of AKR1B10 was detected by Western blot assay and real-time fluorescence quantitative PCR (RT-qPCR). Decreased AKR1B10 activity was detected by reduced coenzyme II (NADPH) absorbance at 340 nm. The low expression of AKR1B10 and the effect of different concentrations of epalrestat on cell proliferation and cell cycle were detected by CCK-8 method and flow cytometry. The protein expression levels of p-rb, cyclin D1, E1, p27 in HepG2 cells were detected by Western blot. The mean of the two samples was tested using independent sample t-test. Results: AKR1B10 expression level in hepatoma cells was significantly increased compared to normal liver cells, and the relative expression level of AKR1B10 protein in HepG2 cells was 6.71 ± 1.11 (P = 0.012). Epalrestat was significantly inhibited with the enzymatic activity of AKR1B10 in a dose-dependent manner. AKR1B10 gene in HepG2 cells was effectively silenced. HepG2 cells treated with different concentrations of epalrestat (AKR1B10 inhibitor) for 24, 48 and 72 h had inhibited cell proliferation, promoted G0/G1 cell cycle arrest, reduced the expression of p-Rb, cyclin D1, and cyclin E1 and increased the expression of cyclin dependent kinase inhibitor p27 expression. Conclusion: AKR1B10 inhibitory expression and activity can promote G0/G1 cell cycle arrest in HepG2 cells through the p27 / p-Rb pathway.

目的 探讨急性髓系白血病(AML)的克隆异质性特征及其临床价值。 方法 采用高通量测序技术靶向检测2016年1月至2019年6月河南省肿瘤医院收治的465例AML患者的68种相关基因,将检出的基因突变位点根据变异等位基因频率(VAF)及同期流式细胞学结果进行克隆异质性分析,并分析其与预后的关系。 结果 338例(81.4%)初诊患者检出基因突变,其中携带DNMT3A、NRAS和RUNX1突变患者出现2个及以上克隆比例显著增加(DNMT3A:χ2=15.231, P<0.001;NRAS:χ2=19.866, P<0.001;RUNX1:χ2=23.647, P<0.001)。不同年龄组间克隆数差异有统计学意义(χ2=17.505, P=0.022),其中>60岁患者携带2个和≥3个克隆的比例增加。初诊患者与复发或继发AML患者间克隆分布差异具有统计学意义(χ2=11.302, P=0.010),且患者多克隆的比例随预后危险度增加而逐渐增加(χ2=17.505, P=0.022)。而主克隆分析中,RUNX1突变标志的主克隆比例较高(χ2=4.527, P=0.033)。克隆异质性与疗效相关分析显示,携带3个及以上克隆患者的总生存(OS)期和无进展生存(PFS)期均远低于其他患者(OS:χ2=13.533,P=0.004;PFS:χ2=9.817,P=0.020),而在中危组患者中,克隆数目多的患者其PFS期显著缩短(χ2=10.883,P=0.012)。Cox回归多因素分析显示,携带3个及以上克隆为影响预后的独立危险因素,其OS期和PFS期显著短于无克隆患者(OS:HR=3.296,95%CI 1.568~6.932,P=0.002;PFS:HR=3.241,95%CI 1.411~7.440,P=0.006)。 结论 克隆异质性可反映肿瘤的生物学特性,提示其耐药性、难治性及侵袭性,可进一步用来评估疗效和AML中危组患者的预后。

Abstract
Plasma flows encountered in high-energy-density experiments display features that differ from those of equilibrium systems. Nonequilibrium approaches such as kinetic theory (KT) capture many, if not all, of these phenomena. However, KT requires closure information, which can be computed from microscale simulations and communicated to KT. We present a concurrent heterogeneous multiscale approach that couples molecular dynamics (MD) with KT in the limit of near-equilibrium flows. To reduce the cost of gathering information from MD, we use active learning to train neural networks on MD data obtained by randomly sampling a small subset of the parameter space. We apply this method to a plasma interfacial mixing problem relevant to warm dense matter, showing considerable computational gains when compared with the full kinetic-MD approach. We find that our approach enables the probing of Coulomb coupling physics across a broad range of temperatures and densities that are inaccessible with current theoretical models.

Abstract
Objective: To explore the characteristics and clinical significance of clonal heterogeneity in patients with acute lymphoblastic leukemia(ALL). Methods: From January 2016 to June 2019, 170 newly diagnosed ALL patients were enrolled in the Department of Hematology, Henan Cancer Hospital, including 93 males and 77 females, with a median age of 17 (2-80) years. Fifty-two ALL-related genes were detected by high-throughput sequencing technique. The clonal heterogeneity of mutations was analyzed according to the variant allele frequency (VAF) and the results of flow cytometry. The prognostic value of mutations was also evaluated. Results: Gene mutations were detected in 121 (71.2%, 121/170) patients, of which 2 or more clones were detected in 18 (52.9%, 18/34) T-cell acute lymphoblastic leukemia patients, while only 23 (16.9%, 23/136) B-cell acute lymphoblastic leukemia patients were positive of multiple mutations (P<0.01).Gene mutation-related clonal heterogeneity analysis showed that 2 or more clones were frequent in patients with NOTCH1 mutations (13/19 patients) (P<0.01). Event free survival (EFS) in patients with 3 or more clones was significantly lower than other patients (χ(2)=10.330, P=0.016). Child ALL patients had similar result, that multiple clones predicted lower overall survival (OS) and EFS (OS: χ(2)=7.974, P=0.047; EFS: χ(2)=10.860, P=0.013). Conclusion: Clonal heterogeneity in ALL patients is closely related to the different origin of lymphocyte lineages and the age of onset, which may reveal the nature of the disease and predict the clinical outcome.

Abstract
Objective: To investigate the relationship between gene mutation characteristics, mutation burden and general condition, disease subtype and karyotype of patients with myelodysplastic syndrome (MDS), and its clinical value. Methods: High-throughput sequencing was used to detect 65 blood tumor-related genes in 191 MDS patients and 9 secondary acute myelocytic leukemia patitents(SAML), and to analyze the characteristics of abnormal genes, mutation burden, as well as the relationship with disease subtypes, chromosome karyotypes and age. Results: Mutations were found in 148 patients (77.5%), including 47 abnormal genes and 186 mutation sites. And gene mutations were found in 9 SAML patients, the number of mutations was significantly higher than that in MDS patients (χ(2)=11.911, P=0.018). Among the abnormal genes, the mutation frequency of U2AF1 (37.3%) and ASXL1 (41.6%) were higher, and there were significant differences in mutation burden among different abnormal genes (F=91.946, P<0.001). There were differences in the number of gene mutations among different subtypes of MDS, and the number of EB-2 gene mutations was the highest (2.2±1.5). In SLD, MLD, EB-1 and EB-2, the proportion of carrying ≥ 3 mutations increased gradually (χ(2)=52.471, P=0.037). TP53 mutation was associated with abnormal karyotype (r(φ)=0.177, P=0.019), especially with complex karyotype (r(φ)=0.440, P<0.001), while NPM1 mutation is associated with normal karyotype (r(φ)=0.173, P=0.024). The number of mutations carried by patients under 30 years old was the least, and the number of mutations increased with the increase of age. The number of mutations was the most in patients aged 60 to 79 years old (P=0.017), and the mutation frequency of epigenetic related genes increased with the increase of age (P=0.041). Conclusions: The mutation characteristics and mutation load of MDS-related genes are closely related to clinical factors such as disease subtype, chromosome karyotype and patient age.

Abstract
Weyl semimetals are crystalline solids that host emergent relativistic Weyl fermions and have characteristic surface Fermi-arcs in their electronic structure. Weyl semimetals with broken time reversal symmetry are difficult to identify unambiguously. In this work, using angle-resolved photoemission spectroscopy, we visualized the electronic structure of the ferromagnetic crystal Co3Sn2S2 and discovered its characteristic surface Fermi-arcs and linear bulk band dispersions across the Weyl points. These results establish Co3Sn2S2 as a magnetic Weyl semimetal that may serve as a platform for realizing phenomena such as chiral magnetic effects, unusually large anomalous Hall effect and quantum anomalous Hall effect.

Abstract
Objective: To evaluate the effect of extraocular muscle surgery in treating secondary esotropia with diplopia after orbital decompression for thyroid-associated ophthalmopathy (TAO). Methods: Retrospective case series study. Eleven secondary esotropic patients with diplopia after orbital decompression for TAO who underwent extraocular muscle surgery during March 2016 and October 2018 in Tianjin Eye Hospital were included. All patients had new onset esotropia after decompression surgery and underwent strabismus surgery. Deviation angle, diplopia, and ocular movement were observed preoperatively and postoperatively. Surgeries were carried out under the monitored anesthesia care combined with local anesthesia, and the eye alignment was adjusted to orthotropia with no diplopia in the operation with the technique of intraoperative adjustable suture and forced duction test results. All the patients were followed up. Results: The ages of the patients were from 26 to 42 years (1 male and 10 females). The deviation angles were 10-98 prism diopter. Orbital CT scan showed that the horizontal rectus thickness was increased at different levels, and the thickness of the medial rectus was increased more than that of the lateral rectus. Two patients had monocular medial rectus recession only, 2 had bilateral medial rectus recession only, 2 had monocular medial rectus recession combined with lateral rectus resection, and the other 5 had bilateral medial rectus recession with monocular lateral rectus resection. The recession of medial rectus muscle was 3.5 to 7.5 mm in 11 patients and 2.0 to 6.0 mm in 7 patients with the resection of lateral rectus muscle. Diplopia of the 11 patients disappeared with orthotropia at primary gaze position after the extraocular muscle surgery. The limitation of abduction changed from preoperative (-1.91±1.04) to postoperative (-0.64±0.81). All the patients were satisfied with the surgical results. At the end of the follow-up (6 to 24 months), the results of the patients were stable, and no over-correction was found. Conclusion: Extraocular muscle surgery with intraoperative adjustable suture technique can effectively treat TAO patients with secondary esotropia with diplopia after orbital decompression.

Abstract
Objective: To investigate the safety and efficiency of ultrasonic bone curette used in anterior cervical discectomy and fusion surgery. Methods: As a retrospective study, we collected and analyzed the clinical data of 47 patients receiving anterior cervical discectomy and fusion surgery in Luohe Central Hospital from January 2014 to January 2017, there were 26 males and 21 females with a mean age of (52±9) years. According to the different surgical tools used in the process of decompression by resecting osteophytes or bone like an inverted Chinese character "" located at the posterior margin of the vertebral body, the patients were divided into two groups: ultrasonic bone curette group (group A) and traditional tools group (group B). The operating time, volume of intraoperative blood losing, complications, Japanese Orthopedic Association (JOA) score before and after the operation and improvement rate were recorded in the two groups. The t test was used to compare the data between the two groups. Results: In group A, the operating time was (47±7) min, blood loss was (49±4) ml, 1 case experienced urinary tract infection and there was no cerebrospinal fluid leakage or spinal cord injury. In group B, the operating time was (54±12) min and the blood loss was (117±16) ml, cerebrospinal fluid leakage occurred in 2 patients and the incision healed one-stage by local compression, hoarseness happened in 1 case and it disappeared after 2 weeks, 2 patients had swallowing discomfort and recovered in one month, no spinal cord injury occurred in this group. The operating time and blood loss in group A were lower than those in group B (t=2.691, 20.704, both P<0.05). And the incidence of complications in group A were lower than that in group B (χ(2)=4.157, P=0.041). The JOA score of group A at 3 days after surgery was improved for 39.0% when compared with that before the surgery, and it was improved for 71.6% at one year after the surgery. The JOA score in group B at 3 days after surgery was elevated for 38.7% from that before the surgery, and it increased for 69.4% at one year after the surgery. There was no significant different in JOA score before the surgery, 3 days and one year after the surgery between the two groups (t=0.611, 1.076, 0.061, all P>0.05). Conclusion: In the process of decompression by resecting osteophytes or bone located at the posterior margin of the vertebral body in the anterior cervical discectomy and fusion surgery, ultrasonic bone curette is safe and effective, and it can effectively shorten the operating time, decrease the blood loss and cut down the incidence of complications.
