Abstract
Objective: To explore the histopathological factors affecting the stiffness of papillary thyroid carcinoma (PTC). Methods: Ninety-six patients with PTC confirmed by surgery and pathology in Shanxi Bethune Hospital from January 2019 to December 2020 were selected, including 101 nodules. Two-dimensional ultrasound and shear-wave elastography (SWE) were performed before surgery and the average Young's modulus (Emean) of PTC nodules were measured. Histopathological examinations on the nodules were conducted after surgery to decide the lesion size, number of lesions, calcification type, presence or absence of capsular and extracapsular invasion, degree of fibrosis, microvessel density, and number of tumor cells. The correlations between the lesion size, degree of fibrosis, microvessel density, and number of tumor cells and the Emean were analyzed. The Emeans of nodules with different numbers of lesions, presence or absence of capsular and extracapsular invasion, and different pathological calcification types were compared. The multiple linear regression analysis was used to evaluate the histopathological factors influencing the Emean. Results: The ranges of the lesion sizes, degrees of fibrosis, microvascular density, numbers of tumor cells, and the Emeans of the 101 investigated PTC nodules were (1.29±0.95) cm, (30.64±18.37)%, (101.64±30.7) vessels per high power field, (373.52±149.87) cells per high power field, and (36.47±19.62) kPa, respectively. Correlation analysis showed that the lesion size of PTC and the degree of fibrosis were positively correlated with the Emean (r=0.660, P<0.001; r=0.789, P<0.001), while the microvessel density was negatively correlated with the Emean (r=-0.198, P=0.047). The Emean of the group with capsular and extracapsular invasion was higher than that of the group without (P=0.014). There were statistical differences in the Emeans among different types of pathological calcification (P<0.001). The multiple linear regression analysis showed that the lesion size (β=0.325, P<0.001), degree of fibrosis (β=0.563, P<0.001), psammoma bodies (β=0.177, P=0.001), stromal calcification (β=0.164, P=0.003), and mixed calcification of both psammoma bodies and stroma (β=0.163, P=0.003) were independent influencing factors for the Emean. The degree of fibrosis had the greatest impact on the Emean. Conclusions: The Emean of PTC lesions was correlated with the histopathological characteristics of PTC. The lesion size, degree of fibrosis, and calcification had significant impact on the Emean, among which the degree of fibrosis had the greatest impact.

Abstract
As a representative work of materia medica in the Ming Dynasty, the plant images attached to Compendium of Materia Medica retain the results of Li Shizhen's research on the original plants of medicinal materials in another form, which truly reflects the understanding and utilization of herbs in the Ming Dynasty.Taking the image of fragrant plants in Wood section in the book as an example, the original of the plants depicted in the images is examined to reveal the level of understanding of plant knowledge and medicinal properties in the Ming dynasty.Among the 25 images contained in the woody section, 20 images accurately depict the leaves, flowers and fruits of plants, and the description of the morphological details of the plant Cephalotaxus fortunei Hook. f. proves a high level of understanding of plant morphology and medicinal properties at the time. However, the errors of a total of 5 diagrams such as Wuyao and A wei also showed limitations. By comparing the results of the image with the medicinal properties contained in the text,it is clear that the level of understanding of medicinal properties is very high in the Ming dynasty, and the understanding of the medicinal properties of some plants is even higher than the understanding of their morphology.

Abstract
Objective: To evaluate the efficacy and safety of pegylated interferon alpha-2b (PEG-IFN-α2b) in the treatment of myeloproliferative neoplasm (MPN). Methods: Thirty-four MPN patients receiving PEG-IFN-α2b treatment in the Second Hospital of Tianjin Medical University from August 2019 to October 2022 were prospectively included. Among the patients, 9 were male and 25 were female, and the median age [M (Q1, Q3)] was 57 (19, 78) years. Patients' clinical characteristics were collected and the follow-up was performed. As of January 30, 2023, the follow-up period [M(Q1, Q3)] was 24 (16, 33) months. The efficacy, safety and changes in immune cell and cytokine levels after 12 and 24 months of treatment were analyzed. Results: During the follow-up period, 4 patients dropped out, and the efficacy was evaluable in 30 patients. Following 12 and 24 months of treatment, the complete hematologic response (CHR) rates were 57.1% (16/28) and 75.0% (18/24), respectively. The complete molecular response (CMR)+partial molecular response (PMR) rates were 27.3% (6/22) and 55.0% (11/20), respectively. The bone marrow histopathological overall response rates (ORR) were 34.6% (9/26) and 47.6% (10/21), respectively. At 12 and 24 months of treatment, the proportions of CD8+HLA-DR+T cells, effector T cell subpopulations, CD56bright natural killer (NK) cells, and plasmacytoid dendritic cells (pDC) were higher than the pre-treatment levels, while the proportion of CD56dim NK cells was lower than the pre-treatment level (all P<0.05). The levels of motif chemokine ligand 10 (CXCL10), tumor necrosis factor (TNF)-α and TNF-β in bone marrow all increased from those prior to treatment, while the levels of vascular endothelial growth factor (VEGF) and interleukin (IL-4) decreased from those prior to treatment (all P<0.05). Among hematological adverse reactions, white blood cells decrease [47% (16/34)] was observed with high incidence. Among non-hematological adverse reactions, asthenia [44.1% (15/34)] and transaminases increase [32.3% (11/34)] were observed with high incidences. Conclusions: PEG-IFN-α2b has high hematologic, molecular, and bone marrow histopathological response rates in the treatment of MPN. It can reduce malignant clone loads and regulate the immune microenvironment and is safe and well tolerated overall.

Abstract
Objective: To analyze the risk factors of thrombosis in patients with JAK2V617F mutation positive myeloproliferative neoplasms (MPN). Methods: A total of 223 MPN patients with JAK2V617F mutation in the Second Hospital of Tianjin Medical University from September 2017 to May 2023 were retrospectively enrolled, including 111 males and 112 females, aged [M(Q1,Q3)] 57(21,66) years. According to the presence or absence of thromboembolism during follow-up, the patients were divided into thrombosis group (n=102) and non-thrombosis group (n=121). The clinical characteristics, laboratory characteristics, cytogenetics and other disease progression and survival of the two groups of patients were analyzed. As of March 31, 2023, the follow-up period [M (Q1, Q3)] was 6 (3, 10) years. The influencing factors of thrombosis in JAK2V617F positive MPN patients were analyzed by using the Cox risk model. Results: Among 223 JAK2V617F positive MPN patients, 144 were polycythemia vera (PV), 51 were essential thrombocythemia (ET) and 28 were primary myelofibrosis (PMF). The mutation rates of ASXL1 and BCORL1 genes in the thrombosis group were 19.6% (20/102) and 6.9% (7/102), respectively, which were higher than those in the non-thrombosis group [9.1% (11/121) and 0.8% (1/121)] (both P<0.05). The proportion of monocytes, C-reactive protein (CRP), interleukin-1β (IL)-1β, IL-8 and tumor necrosis factor-β (TNF-β) increased in the thrombosis group were higher than those in the non-thrombosis group (all P<0.05). Multivariate analysis showed that age≥60 years (HR=2.132, 95%CI: 1.376-3.303, P=0.001), history of thrombosis (HR=3.636, 95%CI: 2.121-6.202, P<0.001), ASXL1 mutation positive (HR=2.245, 95%CI: 1.093-3.231, P=0.022) and elevated TNF-β (HR=2.009, 95%CI: 1.113-3.624, P=0.021) were risk factors for thrombosis in JAK2V617F positive MPN patients. Conclusions: In addition to age, history of thrombosis and positive ASXL1 mutation, elevated TNF-β is also an influencing factor of thrombosis in JAK2V617F positive MPN patients. Intervention of inflammation may have a certain effect on the prevention and treatment of thrombosis.

Abstract
Objective: To explore the clinical and laboratory characteristics of SF3B1 gene mutations in myeloproliferative neoplasms (MPN) patients. Methods: The clinical data of 273 MPN patients who were diagnosed MPN and treated in the Second Hospital of Tianjin Medical University from November 2017 to March 2023 were retrospectively analyzed. There were 133 males and 140 females, with a median age M(Q1,Q3)of 56(46, 67) years. The molecular biology and cytogenetic characteristics were detected by second-generation sequencing (NGS) and R+G banding techniques, and the clinical and laboratory characteristics of patients with SF3B1 gene mutation were analyzed. Results: SF3B1 gene mutations were found in 13 patients (4.8%, 13/273).The types of SF3B1 mutations included missense (92.3%, 12/13) and nonsense mutations (7.7%, 1/13).Compared to the non-mutant cohort, patients in SF3B1 mutant cohort had older ages [68(51, 76) vs 56(45, 66)years,P=0.025], higher proportion of splenomegaly [46.2%(6/13) vs 15.8%(41/259),P=0.014]and secondary tumor [23.1%(3/13)vs 3.8%(10/260), P=0.018]with higher proportion of bone marrow blast [0.5%(0, 1.5%) vs 0(0, 0.5%),P=0.002] and lower hemoglobin[(104±36) vs (137±40) g/L,P=0.004] and hematocrit [31%(22%, 40%) vs 41%(35%, 52%),P=0.003]. All of the 10 patients in the SF3B1 mutant cohort whose ring sideroblast (RS) could be evaluated showed no RS formation. The overall survival, thrombosis-free survival and leukemia free survival of MPN patients in SF3B1 mutant cohort were 4.0 (2.0, 6.0), 2.0 (0.5, 4.5) and 4.0 (2.0, 6.0) years, respectively, while patients in the non-mutant cohort were 6.0 (3.0, 10.0), 5.0 (1.0, 8.0), 6.0 (3.0, 10.0) years, respectively, there were no statistical significance between two groups (Z=3.69, 1.66, 2.05, all P>0.05).The secondary tumor free survival of SF3B1 mutant cohort patients was 4.0 (2.0, 6.0) years, which was lower than that of non-mutant cohort patients [5.5 (3.0, 10.0) years, Z=18.18, P<0.001). Conclusions: MPN patients with SF3B1 gene mutations are older, more prone to splenomegaly and secondary tumors. They also have a higher proportion of bone marrow blast, lower hemoglobin and hematocrit, and show no RS formation.

Abstract
Objective: To assess the clinical features and relative factors of left ventricular hypertrophy (LVH) in children with primary hypertension. Methods: In this retrospective cohort study, 430 children diagnosed with primary hypertension in Children's Hospital, Capital Institute of Pediatrics from January 2019 to September 2022 were enrolled. Their clinical data was analyzed and LVH was assessed by echocardiography. According to left ventricular geometry, these children were assigned to the LVH group and normal geometry group. General conditions, laboratory indicators and ambulatory blood pressure parameters between two groups were compared by independent sample t-test or Mann-Whitney U test. Spearman correlation coefficient was used to analyze the correlation between LVH and clinical indicators including blood pressure, biochemical and metabolic indicators. The independent risk factors of LVH were analyzed by multivariable logistic regression. The receiver operating characteristic (ROC) curve was used to explore the value of risk factors in the diagnosis of LVH. Results: Among the 430 children with primary hypertension, 342 (79.5%) were males and 88 (20.5%) females. Their age was (12.6±2.3) years, and 123 children (28.6%) of them had LVH. Body mass index (BMI) ((30.0±5.2) vs. (26.2±4.3) kg/m2), ratio of stage 2 hypertension (75.6% (93/123) vs. 59.6% (183/307)), 24-hour systolic blood pressure (24 h SBP)((131±10) vs. (128±10) mmHg,1 mmHg=0.133 kPa), daytime systolic blood pressure (SBP) ((135±11) vs. (131±11) mmHg), nighttime SBP ((128±11) vs. (123±10) mmHg), cholesterol level ((4.0±0.7) vs. (3.9±0.7) mmol/L), serum uric acid level ((447±81) vs. (426±91) μmol/L) and incidence of hyperinsulinemia (69.9% (86/123) vs.59.0% (181/307)) were significantly elevated in the LVH group compared with those in the normal geometry group (all P<0.05). There were more patients with a disease course over 5 years in the LVH group than in the normal geometry group, with a statistically significant difference (χ2=8.90,P=0.031). Spearman correlation analysis showed that BMI, 24 h SBP, daytime SBP, nighttime SBP, triglyceride, uric acid, and serum sodium level were positively correlated with LVMI (r=0.43, 0.20, 0.18, 0.18, 0.18, 0.16, and 0.12, all P<0.05). BMI, hyperinsulinemia, and cholesterol level were positively correlated with relative wall thickness (RWT) (r=0.22, 0.12, and 0.16, all P<0.05). The multivariate logistic regression analysis showed that BMI (OR=1.17, 95%CI 1.10-1.25) and 24 h SBP (OR=1.04, 95%CI 1.01-1.08) were the independent risk factors for LVH (both P<0.05). The area under the receiver operator characteristic curve, combined with BMI and 24 h SBP, was 0.72 (95%CI 0.67-0.77, P<0.05), with a sensitivity and specificity of 71.5% and 64.8%, respectively. Conclusions: BMI and 24 h SBP are the independent risk factors for LVH in children with primary hypertension, and the combination of BMI and 24 h SBP has an acceptable diagnostic value for LVH. Early monitoring of these indexes is necessary to predict preclinical cardiac damage.

Abstract
We retrospectively analyzed a rare case of giant pleural tuberculoma. The patient was a female, 62 years old, admitted to hospital for intermittent fever and hemoptysis. The CT scan of the chest and abdomen showed a mass in the right thoracic cavity, and the uneven surface of the bilateral fallopian tubes. Routine blood tests showed a decrease in platelets, white blood cells, and hemoglobin. The mass in the chest was finally confirmed as a tuberculoma by biopsy. The patient was diagnosed with tuberculosis more than 9 years ago and had been treated with anti-tuberculosis drugs for more than 9 years, which caused damage to the liver, bone marrow and other organs, and led to the drug-resistant tuberculosis, making diagnosis and treatment more complex.

Abstract
Oral microbial community, as an important part of human microbial community, is closely related to oral and general health. Oral microbiological research has become the forefront of international microbiological research. Standardized and unified nomenclature for oral microorganisms in Chinese is of great significance to support the development of oral medicine research. Standardized translation of microbial names is the basis for writing canonical and authoritative professional textbooks and reference books, which helps students to accurately acquire the characteristics and classifications of oral microbes. Unified translation of oral microorganisms is also conducive to academic communication and cooperation, and plays an important role in oral health education and science popularization, which enables oral microbiology knowledge to be accurately disseminated to the public. Therefore, in order to standardize the words in scientific research, funding application, publications, academic exchanges and science popularization within the field of oral medicine, we have fully discussed and revised the Chinese names of oral microorganisms in 2017 edition and ones of newly discovered oral microbes, finally reaching a consensus to form the 2023 edition of Chinese names of oral microorganisms.

Abstract
In the search for natural reservoirs of hepatitis C virus (HCV), a broad diversity of non-human viruses within the Hepacivirus genus has been uncovered. However, the evolutionary dynamics that shaped the diversity and timescale of hepaciviruses evolution remain elusive. To gain further insights into the origins and evolution of this genus, we screened a large dataset of wild mammal samples (n = 1,672) from Africa and Asia, and generated 34 full-length hepacivirus genomes. Phylogenetic analysis of these data together with publicly available genomes emphasizes the importance of rodents as hepacivirus hosts and we identify 13 rodent species and 3 rodent genera (in Cricetidae and Muridae families) as novel hosts of hepaciviruses. Through co-phylogenetic analyses, we demonstrate that hepacivirus diversity has been affected by cross-species transmission events against the backdrop of detectable signal of virus-host co-divergence in the deep evolutionary history. Using a Bayesian phylogenetic multidimensional scaling approach, we explore the extent to which host relatedness and geographic distances have structured present-day hepacivirus diversity. Our results provide evidence for a substantial structuring of mammalian hepacivirus diversity by host as well as geography, with a somewhat more irregular diffusion process in geographic space. Finally, using a mechanistic model that accounts for substitution saturation, we provide the first formal estimates of the timescale of hepacivirus evolution and estimate the origin of the genus to be about 22 million years ago. Our results offer a comprehensive overview of the micro- and macroevolutionary processes that have shaped hepacivirus diversity and enhance our understanding of the long-term evolution of the Hepacivirus genus.

Abstract
Objective: To investigate the mechanism of signal transducer and activator of transcription 3 (STAT3) and cancer associated fibroblasts (CAF) jointly generate chemo-resistance in epithelial-ovarian cancer and their effect on prognosis. Methods: A total of 119 patients with high-grade ovarian serous cancer who received surgery in Cancer Hospital of Chinese Academy of Medical Sciences from September 2009 to October 2017 were collected. The clinico-pathological data and follow-up data were complete. Multivariate Cox regression model was used to analyze the prognostic factors. Ovarian cancer tissue chips of patients in our hospital were prepared. EnVision two-step method immunohistochemistry was used to detect the protein expression levels of STAT3, the specific markers of CAF activation, fibroblast activating protein (FAP), and type Ⅰ collagen (COL1A1) secreted by CAF. The relationship between the expression of STAT3, FAP, COL1A1 protein and drug resistance and prognosis of ovarian cancer patients was analyzed, and the correlation between the expression of three proteins was analyzed. These results were verified through the gene expression and prognostic information of human ovarian cancer tissues collected in the GSE26712 dataset of gene expression omnibus (GEO) database. Results: (1) Multivariate Cox regression model analysis showed that chemotherapy resistance was an independent risk factor for overall survival (OS) of ovarian cancer (P<0.001). (2) The expression levels of STAT3, FAP, and COL1A1 proteins in chemotherapy resistant patients were significantly higher than those in chemotherapy sensitive patients (all P<0.05). Patients with high expression of STAT3, FAP, and COL1A1 had significantly shorter OS than those with low expression (all P<0.05). According to the human ovarian cancer GSE26712 dataset of GEO database, patients with high expression of STAT3, FAP, and COL1A1 also showed shorter OS than patients with low expression (all P<0.05), the verification results were consistent with the detection results of ovarian cancer patients in our hospital. (3) Correlation analysis showed that the protein level of STAT3 was positively correlated with FAP and COL1A1 in our hospital's ovarian cancer tissue chips (r=0.47, P<0.001; r=0.30, P=0.006), the analysis of GEO database GSE26712 dataset showed that the expression of STAT3 gene and FAP, COL1A1 gene were also significantly positively correlated (r=0.31, P<0.001; r=0.52, P<0.001). Conclusion: STAT3 and CAF could promote chemotherapy resistance of ovarian cancer and lead to poor prognosis.

Abstract
Objective: To investigate the clinical efficacy of Hintermann osteotomy (H-LCL) for flexible flatfoot. Methods: A follow-up study. Clinical data of 30 patients with flexible flatfoot treated with H-LCL operation from January 2020 to December 2021 in Sports Medical Center of the First Affiliated Hospital of Army Medical University were retrospectively analyzed. There were 8 males and 22 females, with a mean age of (39.0±15.2) years. The mean time from symptom onset to the diagnosis[M(Q1,Q3)]was 24.0 (5.5, 102.0) months. The functional and imaging scores of the patients before and after the last follow-up were compared to evaluate the clinical efficacy of the operation. The functional scores included American Orthopedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) of pain, pain interference (PI) and physical function (PF) index in Patient-Reported Outcomes Measurement Information System (PROMIS). And the imaging scores included Meary's angle, calcaneal pitch angle, calcaneal valgus angle and talonavicular coverage angle. Results: The mean operation time was (82.3±24.4) min, and the follow-up periods was (17.9±6.9) months. At the last follow-up, VAS of pain [M(Q1, Q3)] decreased from 5 (4, 6) to 2 (1, 2); PI decreased from 59.8±5.0 to 44.6±5.7; AOFAS increased from 65.2±10.0 to 85.8±3.3; PF increased from 50 (48.5,51.0) to 58.5 (54.0, 66.0); Meary's angle (antero-posterior image) decreased from 15.7° (10.1°, 29.2°) to 3.9° (2.6°, 5.3°); Meary's angle (lateral image) decreased from 13.5°±6.8° to 4.4°±2.6°; calcaneal pitch angle increased from 14.0°±3.3° to 18.6°±4.2°; calcaneal valgus angle decreased from 12.6°±7.3° to 4.3°±2.5°; and talonavicular coverage angle decreased from 20.9°±10.7° to 7.7°±5.2°. The up-mentioned parameters were all improved statistically significant at the last follow-up when compared with those before the operation (all P<0.05). Conclusion: H-LCL brings a significant improvement of clinical outcome scores and good radiological correction of flatfoot deformities in correcting flexible flatfoot, it conforms to the anatomical characteristics of the subtalar joint.

Abstract
Objective: To explore the clinical features of IgG4-related lung disease. Methods: The clinical data of 60 patients diagnosed with IgG4-related lung disease in Peking University People's Hospital from February 2012 to May 2021 were retrospectively collected. Analysis was made to explore the features of clinical manifestation, laboratory, imaging, prognosis and other characteristics of the disease. Results: A total of 60 patients were included, with 40 males, age of (58.2±12.9) years, an age of onset of (57.1±13.2) years, and 31.7% (19 cases) of the patients had a history of allergic disease. 36.7% (22 cases) of the patients had respiratory symptoms during the disease. 94.6% (53/56) of patients had serum IgG4>1.35 g/L, 24.1% (14/58) of patients had increased eosinophils, 79.2% (38/48) of patients had increased IgE level, and 53.7% (29/54) of patients had decreased C3 or C4. Common imaging findings included nodular changes (38 cases, 63.3%), mediastinal and/or hilar lymphadenopathy (34 cases, 56.7%), and ground glass opacities (31 cases, 51.7%). Fifty-three cases (88.3%) showed two or more imaging changes. The pathological examination of the patient was mainly characterized by lymphoplasmacytic infiltration and fibrosis, with only one case of phlebitis obliterans. Compared with the asymptomatic group (38 cases), patients with respiratory symptoms (22 cases) showed higher level of serum total IgG and eosinophils (43.2 vs 17.8 g/L, 0.30×109/L vs 0.14×109/L, P<0.05), lower proportion of allergic diseases, and higher proportion of consolidation shadows on chest CT (P<0.05). There were no significant differences in serum IgG4, IgE, complement levels, and imaging outcomes after treatment between the two groups (P>0.05). Conclusions: The clinical manifestations of IgG4-related lung disease are atypical, and asymptomatic patients account for a high proportion. The imaging of the disease is highly heterogeneous, and patients are prone to show coexisted multiple imaging changes. The main clinical features and imaging outcomes of patients with and without respiratory symptoms are not significantly different.

Abstract
The current study analyzed the mutation rate of BRAFV600E in papillary thyroid carcinoma patients and the correlation between BRAFV600E mutation and aggressive biological behavior of papillary thyroid carcinoma. A total of 160 patients with papillary thyroid carcinoma who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from October 2020 to November 2021 were retrospectively included. All patients underwent BRAFV600E gene detection. There were 37 males and 123 females, with a mean age of (46.5±11.1) years. The mutation rate of BRAFV600E was 86.3% (138/160). There was no significant correlation between the mutation of BRAFV600E and aggressive factors such as age (P=0.917), single focal/multifocal tumor (P=0.673), tumor size (P=0.360), tumor invasion (P=0.150) and regional lymph node metastasis (P=0.406). Therefore, for papillary thyroid cancer, mutations in a single gene like BRAFV600E fail to determine more active diagnosis and treatment.

Abstract
The Ginzburg-Landau theory, which was introduced to phenomenologically describe the destruction of superconductivity by a magnetic field at the beginning, has brought up much more knowledge beyond the original one as a mean-field theory of thermodynamics states. There the complex order parameter plays an important role. Here we propose a macroscopic theory to describe the features of ferroelectrics by a two-component complex order parameter coupled to nonabelian gauge potentials that provide more freedom to reflect interplays between different measurables. Within this theoretical framework, some recently discovered empirical static and time-independent phenomena, such as vortex, anti-vortex, spiral orders can be obtained as solutions for different gauge potentials. It is expected to bring in a new angle of view with more elucidation than the traditional one that takes the polarization as order parameter.

Abstract
PURPOSE Non-alcoholic fatty liver disease (NAFLD) is considered as both a vital risk factor and a consequence of type 2 diabetes mellitus (T2DM). Low total testosterone (TT) is common in men with T2DM, contributing to increased risks of metabolic diseases. This study aimed to investigate the association between TT levels and the prevalence of NAFLD in men with T2DM. METHODS In this cross-sectional study, 1005 men with T2DM were enrolled in National Metabolic Management Center (MMC) of First Affiliated Hospital of Wenzhou Medical University between January 2017 and August 2021. NAFLD was diagnosed using ultrasound as described by the Chinese Liver Disease Association. Overweight/obesity was defined as body mass index (BMI) ≥ 25 kg/m2 according to WHO BMI classifications. RESULTS Individuals without NAFLD had higher serum TT levels than those with NAFLD. After adjustments for potential confounding factors, the top tertile was significantly associated with lower prevalence of NAFLD compared with the bottom tertile of TT level [odds ratio (OR) 0.303, 95% confidence interval (CI) 0.281-0.713; P < 0.001]. The association between TT with NAFLD in individuals with normal weight (OR 0.175, 95% CI 0.098-0.315; P < 0.001) was stronger than in individuals with overweight/obesity (OR 0.509, 95% CI 0.267-0.971; P = 0.040). There was a significant interaction of TT with overweight/obesity (P for interaction = 0.018 for NAFLD). CONCLUSION Higher serum TT was significantly associated with a lower prevalence of NAFLD in men with T2DM. We found that the relationship of TT and NAFLD was stronger in individuals with non-overweight/obesity.

Abstract
Objective: Based on the Mendelian randomization analysis, to assess the causal relationship between DNA methylation levels of Janus kinase 2 (JAK2) and obesity. Methods: A case-control study was carried out, including 1 021 individuals [obesity (visceral fat index ≥10) vs. no obesity (visceral fat index <10) was 440 vs. 581] from the Henan Rural Cohort Study. MethylTargetTM target region methylation sequencing technology was used for testing the DNA methylation level of JAK2. logistic regression models were used to assess the association between the DNA methylation level of JAK2 and obesity. With SNP as the instrumental variable, the association between the DNA methylation level of JAK2 and obesity was explored by using the Mendelian randomization analysis method. Results: There was a positive association between Chr9:4984943 (one DNA methylation site in the promoter of JAK2) and obesity, and the OR (95%CI) was 1.22(1.04-1.42). Methylation level of five sites in the exon of JAK2 (Chr9:4985378, Chr9:4985404, Chr9:4985407, Chr9:4985409 and Chr9:4985435) were negatively associated with obesity, the corresponding OR (95%CI) were 0.53 (0.29-0.95), 0.58(0.36-0.93), 0.69 (0.49-0.97), 0.72 (0.53-0.99) and 0.58 (0.35-0.98) , respectively. Mendelian randomization analysis showed that there was a causal relationship between the DNA methylation levels of JAK2 and obesity, and the corresponding β (95%CI) were -1.985 (-3.520 - -0.450),-3.547 (-6.301 - -0.792) and -3.900 (-6.328 - -1.472) for Mendelian randomization method of inverse variance weighted, Mendelian randomization method of median based and Maximum-likelihood method, respectively. Conclusion: This study supported there was a causal relationship between the DNA methylation level of JAK2 and obesity.

Abstract
Objective: To investigate the clinical efficacy of the modified Latarjet procedure in the treatment of recurrent anterior subluxation of the shoulder by "coaxial co-arc" reconstruction of the glenoid cavity. Methods: The clinical data of 103 cases (106 shoulders) of recurrent anterior dislocation of the shoulder admitted to the First Affiliated Hospital of the Army Military Medical University from January 2005 to December 2020 were retrospectively studied. Out of these cases, 84 were males and 19 were females; 31 with left-sided injuries while 75 with right-sided injuries, with a mean age of (29.4±11.5) years (16-61 years). The preoperative anterior fear test was positive, and a modified Latarjet procedure was used to reconstruct the shoulder glenoid defect through a "coaxial co-arc". The Rowe score, simple shoulder test (SST) score, and Visual analogue scale (VAS) score of pain were used to assess the shoulder's function. Parameters such as the postoperative shoulder recurrent dislocation rate, shoulder body external rotation angle, and subscapularis muscle strength changes were recorded postoperatively. Moreover, radiographs and CT scans were used to check for the incidence of osteoarthritis (Samson-Prieto score). Results: After a mean follow-up of 9.0 years (1 to 16 years), bony healing occurred 3 to 6 months postoperatively. The Rowe score improved from 40.4±6.5 preoperatively to 93.2±2.5 (P<0.001), the SST score improved from 5.2±1.3 preoperatively to 10.1±1.5 (P<0.001), and the VAS pain score decreased from 3.5±1.9 preoperatively to 1.1±1.2 (P<0.001) at the final follow-up. The angle of lateral external rotation of the shoulder joint was 58.8°±15.6° preoperatively and 57.6°±14.5° postoperatively with no statistically significant difference (P>0.05). There was no statistically significant difference in the measurement of subscapularis muscle strength between the healthy side and the affected side (P>0.05). In 89.6% of patients after surgery, coaxial co-arc reconstruction of the shoulder glenoid was obtained, and the shoulder glenoid defect and postoperative inclusion angle were significantly improved compared with those before surgery (P<0.001). Postoperatively, new-onset osteoarthritis developed in 7 cases (7/98), arthritis progressed in 2 cases (2/8), incisional healing was poor in 2 cases (2/98), and revision surgery was performed in 2 cases (2/98) due to bone mass detachment. Conclusion: Coracoid osteotomy and concentric coaxial reconstruction of the glenoid cavity elicits adequate good clinical efficacy for cases of recurrent anterior shoulder dislocation, with low recurrence rates, low revision rates and low incidence of osteoarthritis.

Abstract
Objective: To screen and analyze the factors affecting the prognosis of replacing single missing tooth by autograft tooth, so as to provide reference for clinical judgment of surgical prognosis. Methods: A total of 176 patients (188 teeth) underwent autotransplantation of teeth in the Department of Oral & Maxillofacial Surgery, School of Stomatology, The Fourth Military Medical University from January 2017 to December 2019, including 85 teeth of males and 103 teeth of females were involved. The age was (33.0±9.8) years (16-65 years). The possible factors affecting the prognosis of replacing single missing tooth by autograft tooth were summarized and grouped, and the clinical and imaging data were recorded and judged. The surgical records and photographic data from the patients' previous medical records were retrospectively analyzed. The survival analysis method was used for statistical analysis to screen out the factors affecting the cumulative survival rate of transplanted teeth. Results: The 5-year cumulative survival rate of 188 transplanted teeth was 88.4%. Univariate Log-Rank analysis showed that age (P<0.001), sex (P=0.008), smoking (P<0.001), position of recipient area (P<0.001), height of alveolar bone in recipient area (P<0.001), time of donor tooth in vitro (P<0.001), use of donor model (P<0.001) and initial stability (P<0.001) were significantly correlated with cumulative survival rate of transplanted teeth. Multivariate Cox proportional hazard regression analysis showed that smoking (β=-2.812, P=0.049), alveolar bone height (β=1.521, P=0.020), donor time (β=-2.001, P=0.019), use of donor model (β=1.666, P=0.034) and initial stability (β=-1.417, P=0.033) were significantly correlated with the cumulative survival rate of transplanted teeth. Conclusions: The prognosis of autogenous tooth transplantation can be predicted by smoking, height of alveolar bone in recipient area, time of donor teeth in vitro, use of donor model and initial stability. Good prognosis of transplanted teeth can be obtained by using donor model during operation, reducing the time of donor teeth in vitro, taking effective methods to restore alveolar bone height, maintaining good initial stability, and good oral health education after operation.

Abstract
Objective: To explore the effect of primary and acquired resistance to anti-human epidermal growth factor receptor 2 (HER-2) on the overall survival of patients with HER-2 positive advanced breast cancer. Methods: The clinical characteristics of HER-2 positive patients with advanced breast cancer admitted to Cancer Hospital of Chinese Academy of Medical Sciences from January 1998 to December 2018 were collected, and their neoadjuvant/adjuvant and advanced three-line chemotherapy were summarized. Among them, targeted drugs for HER-2 included trastuzumab, pertuzumab, T-DM1, RC48-ADC, lapatinib, pyrotinib, allitinib, sipatinib, seratinib. Based on the duration of benefit from anti HER-2 treatment, the patients were divided into two groups: primary anti HER-2 resistance group and acquired anti HER-2 resistance group. In this study, the overall survival (OS) was used as the main end point. Kaplan-Meier analysis and Cox proportional risk regression model were used to analyze the effects of different drug resistance mechanisms on the overall survival. Results: The whole group of 284 patients were included. The median age of recurrence and metastasis was 48 years old, 155 (54.6%) were hormone receptor (HR) positive and 129 (45.4%) were HR negative, 128 cases (45.1%) were premenopausal and 156 cases (54.9%) were postmenopausal, 277 cases (97.5%) had a score of 0-1 in ECoG PS and 7 cases (2.5%) had a score of more than 2 in the first diagnosis of relapse and metastasis. There were 103 cases (36.3%) in the primary drug resistance group and 181 cases (63.7%) in the secondary drug resistance group. The median overall survival time of the two groups was 24.9 months and 40.4 months, respectively, with statistical significance (P<0.001). Conclusion: Primary resistance to HER-2 is one of the factors of poor prognosis in HER-2 positive breast cancer, and its mechanism needs to be further explored.

Abstract
The Xu's Medical Family, from the Northern and Southern Dynasties, was called an official family with medical background by Fan Xingzhun. Its genealogy was traced back to the end of the Sui Dynasty and the beginning of the Tang Dynasty. Based on the local chronicles, epitaphs, history books and relevant medical historical artifacts, this paper explores the development of the Xu's Medical Family in the Yuan and the Ming Dynasties. Most of the Xu's family members were appointed as medical officials locally after Xue Yueweng in the Yuan Dynasty. Xu Shu, Xu Biao, Xu Wei and Xu Wenyuan were appointed as Medical Ambassadors and the judges of Tai Yi Hospital in the Ming Dynasty. Xu Wei was appointed as the Right Tong Zheng in charge of the Tai Yi Hospital affairs in the period of Jia Jing, and promoted to the Chief of Taipu Department in the period of Wan Li in the Ming Dynasty. He was the highest-ranking official in the Xu's Medical Family in the Yuan and Ming dynasties. The Xu's Medical Family were a family of both officials and doctors, to some extent, related to the Yi-Hu System in both the Yuan and the Ming Dynasties. Some of the Xu's family members still took a career as a doctor, but did not serve as medical officers from the Qing Dynasty. Some of the Xu's decendants went into official careers via the Imperial Examination, such as Xu Shifen, as Deputy Minister of Hubu in the Qing Dynasty.

Abstract
This article investigated an occupational chronic benzene poisoning incident that occurred in a sealing material factory in Hebei Province in September 2019, analyzed the clinical data of workers, to explore the causes of occupational chronic benzene poisoning, and summarize the diagnosis and treatment characteristics and treatment outcome. According to GBZ 68-2013 "Diagnosis of Occupational Benzene Poisoning", a total of 12 cases of occupational chronic benzene poisoning were diagnosed among the 20 workers, including 2 cases of occupational chronic mild benzene poisoning, 7 cases of moderate benzene poisoning, and 3 cases of severe benzene poisoning. Both mild and moderate poisoning patients had recovered after treatment. Severely poisoned patients had recovered more slowly, and the white blood cell count was still 2.0×10(9)-3.0×10(9)/L during the 1-year follow-up. This benzene poisoning incident was caused by illegal operations. The responsibility of the employer, the supervision of the administrative agency, and the awareness of personal protection of employees should be strengthened to avoid or reduce the occurrence of poisoning incidents and ensure the health of workers.

Abstract
Objective: To assess the relationship between health-related quality of life (HRQOL) and spinal sagittal parameters in patients with degenerative and isthmic spondylolisthesis before and after surgery, and to provide a biomechanical basis for improving the clinical prognosis of such patients. Methods: A retrospective analysis of 63 patients with lumbar spondylolisthesis who received lumbar fusion surgery in the Department of Spine Surgery, Tianjin Union Medical Center from December 2017 to June 2020 was carried out. There were 16 males and 47 females with a mean age of (59±8) years. Subgroup analyses were conducted based on disease type (degenerative lumbar spondylolisthesis (DS) and the isthmic spondylolisthesis (IS)) and HRQOL scores. Patients were evaluated post-operatively to observe the improvement of symptoms and quality of life. The relationship between operative related factors, HRQOL scores before and after surgery, and spino-pelvic sagittal parameters (including sagittal axis of the spine, lumbar lordosis angle, pelvic incidence angle, pelvic tilt angle (PT), sacral tilt angle, matching degree of pelvic incidence angle (PI) and lumbar lordosis angle (LL), lumbar 1 vertebra plumb line, upper lumbar curve, lower lumbar curve) in the two groups were analyzed. The correlation between the improvement of HRQOL scores and spino-pelvic sagittal parameters in the DS group and the IS group was analyzed and compared. Results: There were significant differences between postoperative HRQOL scores compared with those before the operation in both the DS and IS groups at three times of follow-up after the operation (all P<0.05). There was no difference in the last HRQOL score, the number of surgical segments, operation time and intraoperative blood loss between the two groups (all P>0.05). The parameters of PT and PI-LL in DS patients with VAS back pain score>3 and ≤3 were statistically different (13.7°±6.4° vs 26.6°±7.4°, 5.1°±8.2° vs 18.2°±13.1°, respectively, both P<0.05), similar results were obtained in IS patients (14.1°±6.9° vs 16.4°±8.7°, 2.9°±9.7° vs 6.8°±9.8°, respectively, both P<0.05). In addition, the parameters of PT and PI-LL between patients with ODI>20 and ≤20 were all statistically different in the two groups at the last follow-up after surgery (all P<0.05). The improvement of VAS back pain score in DS and IS groups was significantly related to the improvement of PT value, respectively (r=0.76, 0.78, both P<0.05). The PT, LL and PI-LL were significantly correlated with the ODI in the DS group (r=0.60, 0.62, 0.50, all P<0.05). There was also a correlation between the improvement of ODI and PT, LL and PI-LL in the IS group, respectively (r=0.22, 0.41, 0.76, all P<0.05). Conclusions: Certain correlation exists between the HRQOL and spinal sagittal parameters in patients with degenerative and isthmic spondylolisthesis before and after surgery. For the treatment of lumbar spondylolisthesis and improvement of quality of life, the primary goal is to reconstruct the matching degree of the lumbar lordosis angle and PI, and to reduce the PT value to the normal range by tilting the pelvis forward.

Abstract
Objective: To investigate the clinicopathologic features and outcome of myositis in patients with advanced non-small cell lung cancer treated with immune checkpoint inhibitors. Methods: The patients diagnosed with immune checkpoint inhibitor-related (ICI) myositis in the database of Respiratory Pathology Center of The First Affiliated Hospital, Guangzhou Medical University from June 2019 to December 2020 were retrospectively analyzed. We reported the muscle histology and main clinical manifestations of the patients in this study. Seven patients with advanced non-small cell lung cancer and ICI related myositis were examined; all of the patients were male, with a median age of 64 (range 42-79) years. Results: All seven patients developed myositis under therapy (three for pembrolizumab, three for sintilimab, and one for camrelizumab). Median delay between ICI initiation and myositis onset was 45 (range 15-176) days. Clinical manifestations were dominated by acute or subacute myalgia and limb weakness. Four patients had evidence of myocarditis. In all of the 7 patients, creatine kinase levels were elevated (median 2 354.4, range 468.6-19 709.2 U/L), while myositis-associated antibodies Ro-52 were positive in four patients. Muscle biopsy showed evident multifocal necrotic myofibers and infiltration of inflammation in two patients. Other patients only showed non-specific endomysial inflammation. Infiltration of inflammation mainly consisted of CD8+ T cells and CD68+ histocytes. After the identification of ICI related myositis, ICI treatment was withdrawn in all patients; 6 patients received corticosteroids therapy. All patients had shown marked clinical improvement. Conclusions: ICI myositis presents with remarkably homogeneous and unique clinicopathologic features, and half of the patients exhibit heightened risk for adverse cardiovascular events, which can be life-threatening if not treated in time. Timely identification of these patients, ICI withdrawal and rapid initiation of corticosteroids therapy can significantly improve patient outcome and/or save patients' lives.

Abstract
Objective: To explore the effect of csn2 gene deficiency on starvation tolerance and extracellular polysaccharides (EPS) synthesis in an oligotrophic environment of Streptococcus mutans (Sm). Methods: The csn2 gene deletion strains and complementary strains of Sm were cultivated and then an oligotrophic growth environment for Sm growth by setting different concentration gradient media were created. Cell growth in oligotrophic environment was detected by growth curve. Biofilm volume was measured by crystalline violet staining. Scanning electron microscopy (SEM) and laser confocal microscope were performed to observe the biofilm structure of Sm. The synthesis of EPS was measured by the anthrone-sulfuric acid method. The expression of genes related to EPS synthesis was evaluated by quantitative real-time PCR (qRT-PCR). Results: The growth curve results showed that the deletion of csn2 gene inhibited the growth of Sm under starvation stress. Furthermore, the results of laser confocal microscope showed that the biofilm EPS/bacteria ratios produced by the wild-type strain, csn2 gene-deficient strain and complement strains under nutrient sufficient culture conditions were 0.44±0.07, 1.05±0.13 and 0.57±0.08 respectively, while the ratios of EPS/bacteria in an oligotrophic environment were 0.93±0.24, 3.05±0.21 and 1.32±0.46 respectively, indicating that the deletion of csn2 gene enhanced the ability of extracellular polysaccharide synthesis of Sm in the oligotrophic environment. The expression levels of EPS synthesis-related genes gtfB and gtfC were up-regulated by 2.5 fold and 1.8 fold respectively and the expression level of gtfD was down-regulated by two-thirds. Conclusions: The csn2 gene deficiency showed multiple effects on the physiological functions and virulence characteristics of Sm, including starvation tolerance and EPS synthesis. These changes might be related to the shift of the complex regulative network caused by csn2 gene deletion.

Abstract
This article investigated an occupational chemical poisoning incident that occurred in a certain place in Guangdong Province in September 2020, detected the air at the scene, and analyzed the clinical data of the poisoned patients. The peripheral blood methanol concentrations of the three patients were 307.76 mg/L, 354.80 mg/L and 454.14 mg/L when they were admitted to the hospital. The raw and auxiliary materials were analyzed for volatile organic components. Methyl acetate was detected in the finished glue, synthetic resin and compound machine post glue in the glue room, and the relative percentages were 23.05%, 32.79% and 31.68%, respectively. Through comprehensive analysis, it was judged that this incident was an acute occupational methyl acetate poisoning incident, and 3 workers were poisoned.

Abstract
Objective: To explore the difference of methylation of circRNA related m6A in early inflammation of silicosis and to elucidate the underlying molecular mechanism of circRNA involved in the process of silicosis. Methods: The activation markers of macrophages were detected by Western blotting (WB) in THP-1-derived macrophages. The cell viability was detected with CCK8, by which the stimulation concentration and time of silica were determined. The methylation of total RNA was determined by colorimetry, and the expression of RNA m6A methylase, demethylase and reading protein were detected by Western blotting in mouse model of silicosis. The differential expression of m6A modified circRNA in lung tissues form silicosis and control mice was obtained through Arraystar m6A circRNA epigenetic transcriptome Chip and verified by RT-PCR. Results: The concentration of SiO(2) at 50 μg/cm(2) had the most significant effect on the activation markers and activity of macrophages. Compared with the control group, SiO(2) increased the total RNA m6A level of macrophages, and there were significant differences in the expression of methylase METTL3 and reading protein YTDHF3. High throughput sequencing analysis showed that compared with the control group, the methylation levels of 132 circRNA m6A in the lung of silicosis model mice were increased, while the methylation levels of 296 circRNA m6A were decreased, and then the target circSLC2A13 was screened based on the basic expression. Further verification showed that SiO(2) significantly increased the expression of circSLC2A13 and m6A modification in macrophages. Conclusion: The methylation of circRNA m6A is involved in the activation of macrophages in early inflammation of silicosis.

Abstract
Objective: To understand the epidemiological characteristics of measles outbreaks in China from 2016 to 2020 and related outbreak investigations and response performances. Methods: The information about the incidence of measles outbreaks, the investigation and response of measles outbreaks in 31 provinces from 2016 to 2020 were collected from Measles Surveillance System, and the incidence of suspected measles outbreaks detected through sporadic case finding during the same period according to the measles outbreak definition was analyzed. Results: From 2016 to 2020, a total of 344 measles outbreaks were reported nationwide, involving 1 886 measles cases. The median of intervals between the first case onsets and reported outbreaks ranged from 4 to 10 days, the median of the numbers of involved cases ranged from 2 to 3, and the median of the duration of the epidemic ranged from 8 to 13 days, and some outbreaks had long durations of 65,44,28,63 and 13 days. The top three provinces with high number of reported outbreaks were Gansu, Beijing and Shandong. Among the reported outbreaks, 115 occurred in communities/villages, accounting for the highest proportion. The genotype identification results indicated that all the outbreaks in 2016 were caused by measles virus H1, and the proportion of the outbreaks caused by measles virus H1 decreased year by year since then, which was 88.57% (31/35) in 2017, 85.00% (17/20) in 2018 and 15.79% (3/19) in 2019 respectively. There was no outbreak caused by measles H1 reported in 2020, the 4 isolates all belonged to genotype D8. Active case findings were conducted in local medical institutions for 313 outbreaks, and measles-containing vaccine coverage surveys were conducted for 266 outbreaks. From 2016 to 2020, a total of 919 suspected measles outbreaks were detected nationwide, involving 4 212 measles cases. The top three provinces with suspected measles outbreaks were Xinjiang, Gansu and Sichuan. The suspected measles outbreaks also mainly occurred in communities/villages (493). Conclusions: The number, scale and duration of measles outbreaks were gradually decreasing, the measles outbreaks at the community level can not be ignored, and the local H1 genotypes tend to be gradually replaced by other genotypes. Improving the sensitivity of outbreak surveillance, promoting vaccination, expanding the vaccine coverage, timely and effective response to the outbreaks are the focus of measles elimination in China in the future.

Abstract
In this study, we screened bacterial strains to identify specific probiotics to treat pig diarrhea caused by Escherichia coli or Salmonella. The potential probiotics were assayed for their survival in gastrointestinal solution, their antimicrobial activity, cell-surface properties, adhesion to Caco-2 cells, and inhibition of pathogen adhesion. Nine out of the 20 strains tested showed high tolerance of a simulated gastrointestinal environment and six strains exerted antagonistic effects against enterohemorrhagic E. coli (EHEC) O157:H7 and Salmonella Typhimurium MQ. Lactobacillus johnsonii pDX1e exhibited a higher potent antibacterial activity. Four strains (pDX1a, pDX1e, pDX3a, and pDX5a) displayed auto-aggregation, hydrophobicity, and adhesion to Caco-2 cells similar to those of the reference strain Lacticaseibacillus rhamnosus GG (LGG). Enterococcus durans pDX5a showed the highest adhesion capacity (13.86%), followed by the reference strain LGG (11.20%). All the tested strains competitively suppressed the attachment of pathogens to Caco-2 cells (by 30.73-55.18%); L. johnsonii pDX1e and Ent. durans pDX5a significantly inhibited the adhesion of pathogens by substitution and exclusion, respectively. Therefore, pDX1e and pDX5a were selected as probiotic strains for further investigation and application.

Abstract
In this work we report experimental evidence for the weak high-temperature ferromagnetism in Bi1-x R x FeO3 (R = Dy, Y) compounds by systematic characterizations, excluding the possible side-effects from other iron-based impurities. Remarkable saturated magnetic moment was observed in the Y-substituted samples, Bi1-x Y x FeO3, which is larger than the moment obtained in Bi1-x Dy x FeO3, the Dy-substituted samples with antiferromagnetic background. The physical origin of the weak ferromagnetic transition is discussed and serious lattice distortions have been identified based on the x-ray diffraction and Raman scattering data, although the rhombohedral structure symmetry remains unchanged upon the substitutions. It is believed that the structural distortion suppressed cycloid spin structure is the main factor for the enhanced magnetization in Bi1-x R x FeO3 compounds. Additionally, the Dy3+-Fe3+ antiferromagnetic coupling, which strengthens the antiferromagnetic interaction in Bi1-x Dy x FeO3 compounds, acts as the driving force for the magnetic discrepancy between Bi1-x Y x FeO3 and Bi1-x Dy x FeO3 samples.

Abstract
Objective: To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer. Methods: A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis. Results: The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy (P<0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P<0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P<0.01). Conclusion: Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.

Abstract
Objective: To investigate the effect of mild hypothermia therapy on liver after cardiopulmonary resuscitation. Methods: Thirty-three inbred Chinese Wuzhishan (WZS) minipigs, weighted (28±2) kg, were used to establish a ventricular fibrillation model. And 30 animals survived after cardiopulmonary resuscitation reached basic life support. The surviving animals were randomly divided into two groups: mild hypothermia group (group M, n=15) and conventional treatment group (group C, n=15). All the animals were observed for 24 hours. Blood samples were extracted at baseline, 0.5, 1, 2, 4, 6, 12 and 24 h after successful resuscitation. The concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected at the time points. The enzyme-linked immunosorbent assay (ELISA) was used to detect the concentrations of interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α). The data were compared between the two groups, LSD test was used when the variance was homogeneous, and Tamhane T2 test was used when the variance was uneven. Results: Eleven pigs (73.3%) in the group M and 8(53.3%) in the group C survived at 24 h after successful resuscitation, with no statistically significant difference between the two groups (χ(2)=1.229, P=0.225). After successful resuscitation, the AST, ALT increased in both group but less in M group (all P<0.05). After successful resuscitation, the concentrations of TFN-α and IL-6 in the blood increased in both groups, reached the peak at 4h, and then decreased gradually. The concentrations of TFN-α in group M were lower than those in group C at 0.5, 2, 4 and 6 h after successful resuscitation (t=0.01, 0.01, 0.87, 0.86, all P<0.05). The concentrations of IL-6 in the group M were lower than those in group C at 0.5, 1, 2 and 4 h after successful resuscitation (t=0.23, 0.78, 0.11, 0.80, all P<0.05). Conclusions: After successful resuscitation, the release of inflammatory mediators, such as TNF-α and IL-6, and cell apoptosis may involve in liver ischemia reperfusion injury. After successful resuscitation, the liver undergoes ischemia-reperfusion injury, which may be related to the release of inflammatory mediators such as TNF-α and IL-6. Mild hypothermia therapy can prevent the release of TNF-α, IL-6 to reduce the degree of liver damage after resuscitation.

Abstract
Objective:To investigate the clinical efficacy of "Zhuyuan soup" by combination with fumigation and oral administration on chronic rhinosinusitis(CRS), further exploring effective Chinese medicine for the disease, and giving full play to the unique advantages of external treatment of traditional Chinese medicine. Method:By using randomized and positive drug controlled methods, patients with moderate-to-severe chronic rhinosinusitis were randomly divided into western medicine group and traditional Chinese medicine group, 30 cases in each group. In the western medicine group, the nasal spray hormone Budesonide was used, and the patients in the traditional Chinese medicine group were treated with the traditional Chinese medicine prescription"Zhuyuan soup"by combination with fumigation and oral administration. All of the above patients were followed up for 2 weeks, and 1 course for 1 month. Visual analogue scores were taken at each follow-up, and CT and nasal endoscopy were performed before and after treatment. Result:The total effective of "Zhuyuan soup" group was 67.1%, which was higher than that of western medicine group(59.6%), but there was no statistically significant difference(P>0.05). After treatment, there were no significant differences between the two groups with regard to the symptom of nasal congestion, dizziness, facial pain or fullness, dysosmia, nasal discharge or postnasal drip, total sensation, total symptom score(P>0.05). According to the total symptom score, the effect of the two groups of patients was not significantly correlated with the gender, age, course of disease, alcohol and tobacco hobbies, previous medication and surgery(P>0.05). Based on the results of the study, we found that the Chinese medicine group is superior to the western medicine group in improving the total feeling of the disease, dizziness or headache, facial pain or fullness, and postnasal drip, olfactory disorder. Conclusion:Both traditional Chinese medicine and western medicine are effective methods for treating chronic rhinosinusitis. Clinically, individualized comprehensive treatment should be carried out according to the patient's condition. The above methods may be applied alone or in combination with Chinese and Western medicine. Further optimization and improvement of the combination of traditional Chinese and Western medicine in chronic sinusitis can help improve the clinical efficacy and satisfaction of patients, which deserves further study.

Abstract
The atomic ions with hydrogen reactions play important role in biological chemistry, atmospheric and combustion chemistry. In this work, a full three-dimensional global many-body expansion potential energy surface (PES) for the ground state of H2S-(2A') is reported for the first time, since there is almost no investigations can accurately and completely describe the PES. It is obtained using many-body expansion theory and an extensive set of accurate ab initio energies extrapolated to the complete basis set limit, for improving the accuracy of the potential energy surface. The topographical features of the new three-dimensional global potential energy surface are examined in detail, and found to be in good agreement with theoretical and experimental results. To better test the reaction, such a surface was applied to quasi classical trajectory calculations for S-(2P)+H2(1Σg+)→SH-(1Σ)+H(2S) reaction. The integral cross sections, differential cross sections and the rate coefficients have been computed. Results indicate that such a work can be recommended for corresponding atmospheric dynamics studies and as building blocks for constructing the many body expansion potential energy surface of larger S-/H containing systems.

Abstract
The n-type HgCr_{2}Se_{4} exhibits a sharp semiconductor-to-metal transition (SMT) in resistivity accompanying the ferromagnetic order at T_{C}=106 K. Here, we investigate the effects of pressure and magnetic field on the concomitant SMT and ferromagnetic order by measuring resistivity, dc and ac magnetic susceptibility, as well as single-crystal neutron diffraction under various pressures up to 8 GPa and magnetic fields up to 8 T. Our results demonstrate that the ferromagnetic metallic ground state of n-type HgCr_{2}Se_{4} is destabilized and gradually replaced by an antiferromagnetic, most likely a spiral magnetic, and insulating ground state upon the application of high pressure. On the other hand, the application of external magnetic fields can restore the ferromagnetic metallic state again at high pressures, resulting in a colossal magnetoresistance (CMR) as high as ∼ 3×10^{11}% under 5 T and 2 K at 4 GPa. The present study demonstrates that n-type HgCr_{2}Se_{4} is located at a peculiar critical point where the balance of competition between ferromagnetic and antiferromagnetic interactions can be easily tipped by external stimuli, providing a new platform for achieving CMR in a single-valent system.
