Abstract
Objective: To evaluate the clinical efficacy of posterior lumbar interbody fusion combined with Ponte osteotomy in the treatment of patients with degenerative scoliosis. Methods: The medical records and imaging data of degenerative scoliosis in department of orthopedics, Peking Union Medical College Hospital from 2013 to 2022 were retrospectively collected, and the shortest follow-up time was 1 year. A total of 38 patients were included, including 13 males and 25 females, aged 50-87(65.6±10.9) years old.The follow-up was12-119(43±20) months. Standing position full spine anteroposterior lateral X-ray examinations were performed on all patients preoperatively, postoperatively, and at latest follow-up. The length of hospital stay, complications, operation time, blood loss, instrumented segment, fusion segmen were recorded. The clinical scores and coronasagittal imaging indicators at three time points were compared. Results: The operation time was (274.5±70.5)min, and intraoperative blood loss was (619.2±93.5)ml. The coronal vertical axis was improved from (2.9±1.8)cm preoperatively to (1.2±1.0)cm postoperatively. The preoperative coronal Cobb angle was 16.6°±9.9° and the immediate postoperative correction was 6.4°±4.0°(t=-6.83, P<0.001). The difference was statistically significant (t=-6.12, P<0.001). The coronal Cobb Angle at the last follow-up was 5.7°±3.7°, and there was no significant orthopaedic loss at the last follow-up (t=-6.12, P<0.001).The sagittal vertical axis decreased from (5.6±3.9)cm preoperatively to (3.2±2.5) cm immediately after operation (t=-6.83,P<0.001), and was well maintained at the last follow-up[(2.7±1.8) cm,t=-7.77,P<0.001]. Lumbar lordosis increased from 21.8°±10.2° preoperatively to 35.8°±8.3° postoperatively(t=12.01, P<0.001)and 40.1°±8.6° at last follow-up(t=-10.21, P<0.001). Oswestry disability score (ODI score), visual analogue score (VAS) low back pain score and VAS leg pain score were also lower after surgery than before surgery (all P<0.05). Conclusion: Posterior lumbar interbody fusion combined with Ponte osteotomy can significantly improve the coronal and sagittal plane deformity and postoperative functional score in adult patients with degenerative scoliosis.

Abstract
Objective: To summarize the characteristics of multisystem deformities in patients with Klippel-Feil syndrome (KFS) combined with congenital scoliosis (CS). Methods: Within the framework of the "Deciphering Disorders Involving Scoliosis and Comorbidities (DISCO)" research collaboration, a retrospective analysis was conducted on patients diagnosed with KFS and CS at Peking Union Medical College Hospital between April 2005 and August 2022. Patient data, including imaging examinations and medical records, were collected to summarize the spinal and associated deformities. Results: A total of 82 KFS patients with concurrent CS were included, comprising 42 males and 40 females. The average age was (12.8±8.9) years. Among the KFS patients, there were 31 cases of Type Ⅰ, 12 cases of Type Ⅱ, and 39 cases of Type Ⅲ. The most common location for the major curve of scoliosis was the mid-thoracic segment (42 cases, 51.2%). Hemivertebrae deformities were most frequently observed in the upper thoracic segment (31 cases, 60.8%). There were no statistically significant differences in age, gender, major curve Cobb angle, or region of hemivertebrae occurrence among the different types of KFS (all P>0.05). Apart from spinal vertebral deformities, intraspinal deformities had the highest comorbidity rate (33 cases, 40.2%). The subjects were divided into two groups based on the presence or absence of intraspinal deformity (absence as group G0, presence as group G1), there was a statistically significant difference in the main Cobb angle [M(Q1, Q3)] between the two groups, which was 45.0° (27.5°, 62.0°) and 60.0° (37.5°, 83.5°), respectively (P=0.044). Additionally, a portion of the patients had concurrent cardiovascular system abnormalities (13 cases, 15.9%), craniofacial-ocular-auricular abnormalities (8 cases, 9.8%), genitourinary system abnormalities (7 cases, 8.5%), and gastrointestinal abnormalities (2 cases, 2.4%). Conclusions: Patients with KFS combined with CS commonly present with a major curve of spinal deformity in the mid-thoracic segment and often have comorbidities involving multiple systems. When combined with intraspinal anomalies, the major curve exhibits a greater degree of curvature.

Abstract
Objective: To compare the patient-reported outcomes and short-term clinical outcomes between robotic-assisted and laparoscopic-assisted radical gastrectomy for locally advanced gastric cancer. Methods: This single-center prospective randomized controlled trial was conducted in the Department of Gastrointestinal Surgery,Affiliated Hospital of Qingdao University from October 2020 to August 2022. Patients with locally advanced gastric cancer who were to undergo radical gastrectomy were selected and randomly divided into two groups according to 1∶1, and received robotic surgery and laparoscopic surgery, respectively. Patient-reported outcomes and short-term clinical outcomes (including postoperative complications, surgical quality and postoperative short-term recovery) were compared between the two groups by t test, Mann-Whitney U test, repeated ANOVA, generalized estimating equation, χ2 test and Fisher's exact test. Results: A total of 237 patients were enrolled for modified intention-to-treat analysis (120 patients in the robotic group, 117 patients in the laparoscopic group). There were 180 males and 59 females, aged (63.0±10.2) years (range: 30 to 85 years). The incidence of postoperative complications was similar between the robotic group and laparoscopic group (16.7% (20/120) vs. 15.4% (18/117), χ2=0.072, P=0.788). The robotic group had higher patient-reported outcomes scores in general health status, emotional, and social domains compared to the laparoscopic group, differences in time effect, intervention effect, and interaction effect were statistically significant (general health status: χ2 value were 275.68, 3.91, 6.38, P value were <0.01, 0.048, 0.041; emotional: χ2 value were 77.79, 6.04, 6.15, P value were <0.01, 0.014, 0.046; social: χ2 value were 148.00, 7.57, 5.98, P value were <0.01, 0.006, 0.048). However, the financial burden of the robotic group was higher, the differences in time effect, intervention effect and interaction effect were statistically significant (χ2 value were 156.24, 4.08, 36.56, P value were<0.01, 0.043,<0.01). Conclusion: Compared to the laparoscopic group, the robotic group could more effectively relieve postoperative negative emotions and improve recovery of social function in patients.

Abstract
Objective: This study aims to explore the causal relationship between obstructive sleep apnea (OSA) and type 2 diabetes (T2D) using bidirectional Mendelian randomization (MR). Methods: The genetic data related to OSA were obtained from the FinnGen Biobank (Ncase=16, 761, Ncontrol=201, 194) in the Genome-wide association study (GWAS). Three single nucleotide polymorphism (SNP) were screened out as instrumental variable (IV) of OSA. The genetic data related to T2D were derived from a large Meta-analysis of GWAS (Ncase=62, 892, Ncontrol=596, 424), 114 SNP were selected as IV of T2D. Multiple MR methods were used for analysis and inverse variance weighted (IVW) was performed as main method. The sensitivity of MR analytic results was analyzed using MR-Egger and other methods, and the IV was evaluated using F-value statistics. Results: MR analysis showed that OSA was significantly associated with increased risk of T2D (OR=2.016, 95%CI: 1.185-3.429, P<0.05). There was no significant relationship between T2D and OSA risk (OR=1.030, 95%CI: 0.980-1.082, P=0.238). There was heterogeneity in both-way results (OSA➝T2D, P=1.808×10-11; T2D➝OSA, P=1.729×10-7), and no horizontal pleiotropy (OSA➝T2D, P=0.477; T2D➝OSA, P=0.349). IV of OSA and T2D-selected in the study were strong instrumental variables (F statistics of OSA=20.543; F statistics of T2D=30.117). Conclusion: Our results supported that OSA was a risk factor for T2D, but T2D had no significant impact on the incidence of OSA. Blood glucose monitoring and diabetes screening in OSA patients might be beneficial to the early detection and intervention of T2D.

Abstract
Objective: To examine the association between smoking status and related mortality among elderly people aged 60 and above in urban and rural areas of Beijing City. Methods: Based on Beijing City Elderly Comprehensive Health Cohort Study from 2009 to 2014, a total of 4 499 eligible older adults included in the baseline survey were followed up and investigated to collect information on survival and death. The Cox proportional hazards regression model was used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs), and the dose-response relationship was estimated between the smoking index, the years of quitting and mortality. Results: The median (IQR) age of 4 499 subjects was 70.00 (10.00) years old, including 1 814 (40.32%) males. The proportion of non-smokers, former smokers and current smokers was 69.50% (3 127/4 499), 13.20% (594/4 499) and 17.30% (778/4 499), respectively. After adjusting for confounding factors such as demographic and sociological characteristics, lifestyle, etc., the results of multivariate Cox regression analysis showed that, compared to non-smokers, former smokers had a 30.6% increased risk of all-cause mortality [HR (95%CI): 1.306 (1.043-1.636)] and the HR (95%CI) of all-cause, malignant tumor and lung cancer mortality among current smokers has increased by 50.0% [HR (95%CI): 1.500 (1.199-1.877)], 80.3% [HR (95%CI): 1.803 (1.226-2.652)] and 212.6% [HR (95%CI): 3.126 (1.626-6.012)], respectively. The smoking index was positively associated with the increased risk of all-cause, malignant tumor and lung cancer mortality, while the years of smoking cessation were negatively associated with that risk (P<0.05). Conclusion: Smoking is associated with tobacco-related mortality among elderly people in Beijing City.

Abstract
Objective: Risk factors related to residual cancer or lymph node metastasis after endoscopic non-curative resection of early colorectal cancer were analyzed to predict the risk of residual cancer or lymph node metastasis, optimize the indications of radical surgical surgery, and avoid excessive additional surgical operations. Methods: Clinical data of 81 patients who received endoscopic treatment for early colorectal cancer in the Department of Endoscopy, Cancer Hospital, Chinese Academy of Medical Sciences from 2009 to 2019 and received additional radical surgical surgery after endoscopic resection with pathological indication of non-curative resection were collected to analyze the relationship between various factors and the risk of residual cancer or lymph node metastasis after endoscopic resection. Results: Of the 81 patients, 17 (21.0%) were positive for residual cancer or lymph node metastasis, while 64 (79.0%) were negative. Among 17 patients with residual cancer or positive lymph node metastasis, 3 patients had only residual cancer (2 patients with positive vertical cutting edge). 11 patients had only lymph node metastasis, and 3 patients had both residual cancer and lymph node metastasis. Lesion location, poorly differentiated cancer, depth of submucosal invasion ≥2 000 μm, venous invasion were associated with residual cancer or lymph node metastasis after endoscopic (P<0.05). Logistic multivariate regression analysis showed that poorly differentiated cancer (OR=5.513, 95% CI: 1.423, 21.352, P=0.013) was an independent risk factor for residual cancer or lymph node metastasis after endoscopic non-curative resection of early colorectal cancer. Conclusions: For early colorectal cancer after endoscopic non-curable resection, residual cancer or lymph node metastasis is associated with poorly differentiated cancer, depth of submucosal invasion ≥2 000 μm, venous invasion and the lesions are located in the descending colon, transverse colon, ascending colon and cecum with the postoperative mucosal pathology result. For early colorectal cancer, poorly differentiated cancer is an independent risk factor for residual cancer or lymph node metastasis after endoscopic non-curative resection, which is suggested that radical surgery should be added after endoscopic treatment.

Abstract
OBJECTIVE To study the effect of propofol used for painless gastroscopy and colonoscopy on psychomotility recovery. METHODS One hundred adult patients undergoing painless gastroscopy and colonoscopy were recruited, aged 18-72 years, with American Society of Anesthesiologist (ASA) physical status Ⅰ-Ⅱ. According to age, the patients were divided into youth group (20-39 years old, 27 cases), middle age group (40-54 years old, 37 cases), and elder group (55-64 years old, 36 cases). Propofol was continuously infused according to the patients' condition to mantain the bispectal index (BIS) score 55-64. All the patients received psychomotility assesment 30 min before the operations when the discharge criteria were met including number cancellation test, number connection test and board test. The heart rate, blood pressure, saturation of pulse oximetry, electrocardiograph and BIS were monitored during the operation. The operating time, recovery time, total volume of propofol and discharge time were recorded. If the results obtained were inferior to those before operation, a third assessment was taken 30 minutes later until the results recovered or being superior to the baseline levels. RESULTS All the patients completed the first and second assessments, and 25 patients had taken the third assessment. There was no statistically significant difference in the results of psychomotility assessment when the patients met the discharge standard. Furthermore, the results were analyzed by grouping with age, and there was no statistical difference in the test results of the youth and middle age groups compared with the preoperative group, among which, the efficiency of the number cancellation test was significantly better than that before operation in the youth group (P < 0.05). However, in the elderly patients the number cancellation efficiency, number connection test and board test were significantly inferior to that before operation (P < 0.05). There was no significant difference in the accuracy of number cancellation compared with that before operation. The patients who needed the third test in the elder group were significantly more than in the other groups (P < 0.05). Compared with the preoperative results, there was no statistical difference in the test results of those who completed the third test. CONCLUSION The psychomotility function of the patients who underwent painless gastroscopy and colonoscopy was recovered when they met discharge criteria. The elderly patients had a prolonged recovery period.

Abstract
To evaluate the association between serum anti-tissue transglutaminase antibody (anti-tTG) titers and the severity of histological damage to the duodenal mucosa and to predict a possible anti-tTG cutoff value for diagnosing celiac disease (CD) and villous atrophy in the domestic population. Clinical and pathological data from 76 adult CD patients with positive anti-tTG titers and duodenal biopsy results who were treated at the People's Hospital of Xinjiang Uygur Autonomous Region from July 2017 to January 2022 were retrospectively analyzed. The correlation between anti-tTG titers and the severity of duodenal mucosal damage was statistically assessed to predict the optimal anti-tTG titer cut-off value for diagnosing CD and villous atrophy. Of the 76 patients, 10 had underlying CD, and of the 66 patients with duodenal histopathology, four were Marsh Ⅰ, six were Marsh Ⅱ, and 56 were Marsh Ⅲa-c grade. In adults with CD, anti-tTG titers were shown to be associated with the severity of histological damage to the duodenal mucosa. When the anti-tTG level was ≥5 times the upper limit of normal (ULN), the sensitivity and specificity for diagnosing CD were 83.9% and 92.9%, respectively. When the anti-tTG titer was ≥8 times the ULN, the sensitivity and specificity for diagnosing villous atrophy were 67.9% and 90.0%, respectively. Anti-tTG levels had a strong predictive value for diagnosing CD in adults when titers exceeded 10 times the ULN. Thus, the anti-tTG cut-off value can be combined with clinical judgment to diagnose CD, limiting the use of invasive endoscopy.

Abstract
OBJECTIVE To investigate the prevalence of mountain-type zoonotic visceral leishmaniasis (MT-ZVL) in Yangquan City, Shanxi Province from 2015 to 2020, so as to provide the scientific evidence for formulating the MT-ZVL control strategy. METHODS The epidemiological data pertaining to MT-ZVL cases in Yangquan City from 2015 to 2020 were collected and descriptively analyzed. A Joinpoint regression model was created to analyze the trend in the MT-ZVL incidence in Yangquan City from 2015 to 2020 using annual percent change (APC). The sandflies surveillance data and the prevalence of Leishmania infections in dogs were collected in Yangquan City in 2020, and the regional distribution of sandflies density and sero-prevalence of Leishmania infections in dogs were calculated. In addition, the associations of sandflies density and sero-prevalence of Leishmania infections in dogs with the incidence of human MT-ZVL were examined using the linear correlation analysis. RESULTS A total of 162 MT-ZVL cases were reported in Yangquan City, Shanxi Province from 2015 to 2020, with annual mean incidence of 1.9/105, and there were 4, 7, 16, 27, 33 cases and 75 cases with MT-ZVL reported from 2015 to 2020, appearing a tendency towards a rapid rise (APC = 72.79%, t = 11.10, P < 0.01). MT-ZVL cases were reported across the five counties (districts) of Yangquan City, and the cases predominantly occurred in Jiaoqu District (35.2%, 57/162) and Pingding County (33.3%, 54/162). MT-ZVL cases were predominantly detected in residents at ages of 15 years and older (71.6%, 116/162) and at ages of 0 to 2 years (22.2%, 36/162), with farmers (37.4%, 61/162) and diaspora children (24.5%, 40/162) as predominant occupations. The mean density of Phlebotomus chinensis was 6.3 sandflies per trap per night in Yangquan City from during the period from May to September, 2020, with the highest density observed in Jiaoqu District (12.6 sandflies per trap per night) and the lowest in Yuxian County (1.1 sandflies per trap per night), and there was a region-specific mean density of Ph. chinensis in Yangquan City (H = 17.282, P < 0.01). The sero-prevalence of serum anti-Leishmania antibody was 7.4% (2 996/40 573) in domestic dogs in Yangquan City, with the highest sero-prevalence seen in Jiaoqu District (16.6%, 1 444/8 677), and the lowest in Yuxian County (2.3%, 266/11 501), and there was a region-specific sero-prevalence rate of anti-Leishmania antibody in domestic dogs in Yangquan City (χ2 = 1 753.74, P < 0.01). The sero-prevalence of anti-Leishmania antibody was significantly higher in stray dogs (20.0%, 159/794) than in domestic dogs (χ2 = 176.63, P < 0.01). In addition, there were significant associations among the sandflies density, sero-prevalence of anti-Leishmania antibody in domestic dogs and the incidence of human MT-ZVL (r = 0.832 to 0.870, all P values < 0.05). CONCLUSIONS The prevalence of MT-ZVL appeared a tendency towards a rapid rise in Yangquan City from 2015 to 2020, and systematic interventions are urgently needed for MT-ZVL control.

Abstract
Objective: To analyze the genomic mutation of Mycobacterium tuberculosis (M. tuberculosis) isolated in endogenous activation period and estimate the molecular clock based on the whole genome sequencing data. Methods: Literatures of the whole genome research of endogenous reactivated tuberculosis were retrieved, and the corresponding whole genome sequencing data were downloaded. We extracted the single nucleotide polymorphisms (SNPs) and strain isolation time of initial treatment and relapse of tuberculosis cases, explored the relationship between the different SNPs and interval between initial treatment and relapse by Poisson regression model, calculated the M. tuberculosis molecular clock, and estimated the mutation rate. Results: When the generation time of M. tuberculosis was 18 hours, the mutation rate in 0-2 years, i.e. short-term endogenous activation, was 6.47×10-10 (95%CI: 5.59×10-10-7.44×10-10), which was significantly higher than that in 2-14 years in long term endogenous activation (3.27×10-10, 95%CI: 2.88×10-10-3.69×10-10). The mutation rates of 0-, 1-, 2-, 3-, 5- and 7-14 years were 7.10×10-10, 6.06×10-10, 4.24×10-10, 5.34×10-10, 2.59×10-10 and 1.26×10-10 respectively. Conclusions: In the period of endogenous reactivation, the mutation rate of M. tuberculosis decreases with the interval time between initial treatment and relapse, which verifies the clinically observed phenomenon that the relapse often occurs within two years after the initial treatment of tuberculosis.

Abstract
Objective: To quantitatively evaluate the association between mild cognitive impairment and all-cause mortality. Methods: The research papers of the association between cognitive impairment and all-cause mortality in the elderly in the databases of PubMed, EMBASE, Wang Fang data and CNKI published as of August 1, 2021 were comprehensively retrieved. Software R 4.02 was used for Meta-analysis. Results: A total of 9 research papers were included, involving 48 709 patients. The quality of included papers was high. The results of Meta-analysis showed that the association between mild cognitive impairment and the increased risk of all-cause mortality was statistically significant. Compared with the normal cognitive population, the risk of mortality in the elderly with mild cognitive impairment increased by 39% (HR=1.39, 95%CI: 1.18-1.63). Conclusions: The current research evidence showed that mild cognitive impairment assessed by MMSE screening scale can be used as an independent predictor of the increased risk of all-cause mortality in the elderly population in China. However, due to the limitation of the number of included studies and sample size, the conclusions need to be supported by more evidence studies.

Abstract
Objective: To compare the short-term and long-term outcomes between robotic-assisted and laparoscopic-assisted radical right hemicolectomy in patients with adenocarcinoma of the right colon. Methods: Retrospective review of a prospectively collected database identified 288 right colon cancer patients who underwent either robotic-assisted (n=57) or laparoscopic-assisted right hemicolectomy (n=231) between October 2014 and October 2020 at Department of Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University. There were 161 males and 127 females, aging (60.3±12.8) years (range: 17 to 86 years). After propensity score matching as 1∶4 between robotic-assisted and laparoscopic-assisted right hemicolectomy, there were 56 cases in robotic group and 176 cases in laparoscipic group. Perioperative outcomes and overall survival were compared between the two groups using t test, Wilcoxon rank sum test, χ2 test, Fisher exact test, Kaplan-Meier method and Log-rank test, respectively. Results: The total operative time was similar between the robotic and laparoscopic group ((206.9±60.7) minutes vs. (219.9±56.3) minutes, t=-1.477, P=0.141). Intraoperative bleeding was less in the robotic group (50 (20) ml vs. 50 (50) ml, Z=-4.591, P<0.01), while the number of lymph nodes retrieved was significantly higher (36.0±10.0 vs. 29.0±10.1, t=4.491, P<0.01). Patients in robotic group experienced significantly shorter hospital stay, shorter time to first flatus, and defecation (t: -2.888, -2.946, -2.328, all P<0.05). Moreover, the overall peri-operative complication rate was similar between robotic and laparoscopic group (17.9% vs. 22.7%, χ²=0.596,P=0.465). The 3-year overall survival were 92.9% and 87.9% respectively and the 3-year disease-free survival rates were 83.1% and 82.6% with no statistical significance between the robotic and laparoscopic group (P>0.05). Conclusions: Compared to laparoscopic-assisted right hemicolectomy, robot-assisted right hemicolectomy could improve some short-term clinical outcomes. The two procedures are both achieving comparable survival.

Abstract
OBJECTIVE To investigate the current distribution of ticks and predict the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2017, so as to provide insights into tick control and management of tick-borne diseases in these areas. METHODS All publications pertaining to tick and pathogen distribution in the Yangtze River Delta urban agglomeration were retrieved, and the geographical location of tick distribution was extracted. The effects of 19 climatic factors on the distribution of ticks were examined using the jackknife method, including the mean temperature of the wettest quarter, precipitation of the coldest quarter, mean temperature of the driest quarter, maximum temperature of the warmest month, precipitation of the driest month, minimal temperature of the coldest month, annual precipitation, mean daily temperature range, precipitation seasonality, annual temperature range, temperature seasonality, annual mean temperature, mean temperature of the warmest quarter, precipitation of the wettest quarter, isothermality, mean temperature of the coldest quarter, precipitation of the wettest month, precipitation of the driest quarter and precipitation of the warmest quarter. The distribution of ticks was analyzed in 2020 using the maximum entropy (MaxEnt) model, and the potential suitable habitats of ticks were predicted in 2070 using the MaxEnt model based on climatic data. RESULTS A total of 380 Chinese and English literatures were retrieved, and 148 tick distribution sites were extracted, with 135 sites included in the subsequent analysis. There were 7 genera (Haemaphysalis, Rhipicephalus, Ixodes, Dermacentor, Boophilus, Hyalomma and Amblyomma) and 27 species of ticks detected in the Yangtze River Delta urban agglomeration. The climatic factors affecting the distribution of ticks in the Yangtze River Delta urban agglomeration mainly included the mean temperature of the wettest quarter and the precipitation of the coldest quarter, with 26.1% and 23.6% contributions to tick distributions. The high-, medium- and low-suitable habitats of ticks were 20 337.08, 40 017.38 km2 and 74 931.43 km2 in the Yangtze River Delta urban agglomeration in 2020, respectively. The climate changes led to south expansion of the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2070, and the total areas of suitable habitats of ticks was predicted to increase by 18 100 km2. In addition, the high-, medium- and low-suitable habitats of ticks were predicted to increase to 24 317.84, 45 283.02 km2 and 83 766.38 km2 in the Yangtze River Delta urban agglomeration in 2070, respectively. CONCLUSIONS Multiple tick species are widespread in the Yangtze River Delta urban agglomeration, and the future climate changes may lead to expansion of tick distribution in these areas.

Abstract
This study aimed to investigate the roles of hsa_circRNA_103801 in the progression of osteosarcoma (OS) cells. Quantitative reverse transcription-polymerase chain reaction (RT-qPCR) was used to detect the expression level of circRNA_103801 in OS cells. Cell count kit-8 and Transwell migration and invasion assays were employed to detect the proliferation, migration, and invasion abilities of OS cells. The effects of circRNA_103801 on the apoptosis of OS cells were identified by flow cytometry. The binding relationship between circRNA_103801 and miR-338-3p was verified by bioinformatics analysis. MiR-338-3p level in OS cell lines was detected by RT-qPCR. Additionally, Western blotting was utilized to detect the expression levels of HIF-1, Rap1, PI3K, and Akt in OS cells. The results showed that the expression level of circRNA_103801 was significantly up-regulated in OS patients' tissues. Inhibiting the expression level of circRNA_103801 could attenuate the proliferation, migration, and invasion abilities of OS cells. In addition, the down-regulated expression level of circRNA_103801 could induce cell apoptosis. The results of the luciferase reporter assay suggested that circRNA_103801 could be combined with miR-338-3p, and the RT-qPCR revealed that the miR-338-3p level in OS cells after knockdown of circRNA_103801 was elevated compared with the control group. The results of Western blotting suggested that the expression levels of HIF-1, Rap1, PI3K, and Akt were elevated in OS cells. In conclusion, the circRNA_103801-miR-3388-3p-HIF-1/Rap1/PI3K-Akt pathway could be a therapeutic target of OS.

Abstract
Objectives: To analyze the incidence, blood lipid levels and cardiovascular disease of familial hypercholesterolemia (FH) in dyslipidemia patients receiving lipid-lowing therapy from the DYSIS-China. Methods: Dyslipidemia International Study-China (DYSIS-China) database was re-analyzed according to the criteria of "Chinese guidelines for prevention and treatment of dyslipidemia in adults-2016 version". DYSIS-China database included 25 317 dyslipidemia out-patients who received at least one lipid-lowering drug for at least three months. All the patients were divided into three groups: unlikely HF, possible FH and definite FH according to the Dutch Lipid Clinic Network diagnostic criteria. Age, gender, lipids levels, drug use and complications were compared among the three groups. Factors were compared between Possible FH group and definite FH group in terms of age stratification. Results: A total of 23 973 patients with dyslipidemia were included. The average age was (64.8±9.9) years, 11 757 patients were females (49.0%). The proportion of unlikely FH in the total population was 20 561 (85.7%), possible FH was 3294 (13.7%), and the definite FH was 118(0.5%). Patients in the definite FH group (58.3±8.5 years) was younger than in unlikely HF(65.3±9.8 years) and possible FH(61.8±9.9 years) group. LDL-C ((5.6±1.9) mmol/L) levels were significantly higher in definite FH group than in unlikely HF ((2.5±0.9) mmol/L) and possible FH ((4.3±1.0) mmol/L) group. TC ((7.4±1.8) mmol/L) levels were also significantly higher in definite FH group than in unlikely HF ((4.3±1.0) mmol/L) and possible FH ((6.0±1.0) mmol/L) group. Percent of female sex, sedentary lifestyle and systolic blood pressure value were significantly higher in definite FH group than in other two groups (all P<0.05). Statin use was similar among the 3 groups. Prevalence of ischemic cardiomyopathy (70(59.3%)) was significantly higher in the definite FH group than in unlikely FH group7519 (36.6%) and possible FH group1149 (34.9%). The rate of hypertension (82 (69.5%)) was also significantly higher in the definite FH group than in unlikely FH group (2 063 (62.6%) and in possible FH group (13 928 (67.7%)). The possible FH group had the highest proportion of patients aged 55-64 years (1 146 (34.8%)), and the prevalence of hypertension 358 (76.8%), diabetes 189 (40.6%), ischemic heart disease 186 (39.9%), cerebrovascular disease 149 (32.0%) and heart failure 28 (6.0%) was the highest in patients over 75 years old. The definite FH group had the highest proportion of patients aged 55-64 years (49 (41.52%)), and the prevalence of ischemic heart disease (70 (59.3%)) was the highest in patients aged 45-54 years old group, there was no significant difference in the prevalence of diabetes,hypertension,heart failure,peripheral artery disease and cerebrovascular disease among different age groups. Conclusion: The detection rate of FH in Chinese patients with dyslipidemia is not low, the blood lipid level is poorly controlled, and the risk of cardiovascular disease is high in Chinses FH patients.

Abstract
Objective: To compare the performances of different time series models in predicting COVID-19 in different countries. Methods: We collected the daily confirmed case numbers of COVID-19 in the USA, India, and Brazil from April 1 to September 30, 2020, and then constructed an autoregressive integrated moving average (ARIMA) model and a recurrent neural network (RNN) model, respectively. We applied the mean absolute percentage error (MAPE) and root mean square error (RMSE) to compare the performances of the two models in predicting the case numbers from September 21 to September 30, 2020. Results: For the ARIMA models applied in the USA, India, and Brazil, the MAPEs were 13.18%, 9.18%, and 17.30%, respectively, and the RMSEs were 6 542.32, 8 069.50, and 3 954.59, respectively. For the RNN models applied in the USA, India, and Brazil, the MAPEs were 15.27%, 7.23% and 26.02%, respectively, and the RMSEs were 6 877.71, 6 457.07, and 5 950.88, respectively. Conclusions: The performance of the prediction models varied with country. The ARIMA model had a better prediction performance for COVID-19 in the USA and Brazil, while the RNN model was more suitable in India.

Abstract
Objective: To investigate the protective effect of microRNA 223 (miR-223) on cardiac fibrosis-related signaling pathway and its regulation on expression of Twist family basic helix-loop-helix transcription factor 1 (Twist1) and transforming growth factor-β1 receptor 2 (TGFBR2) in rat cardiomyocytes. Methods: Rat cardiomyocytes (H9c2) were cultured in vitro and treated with TGF-β to induce myocardial fibrosis. The miR-223 group was transfected with miR-223 lentivirus and miR-223-NC group was transfected with miR-223-NC lentivirus. Model group and blank control group had no transfection. Immunocytochemistry staining of alpha-smooth muscle actin (α-SMA) was used to calculate myocardial fibrosis. The mRNA level of miR-223, collagen Ⅰ, collagen Ⅲ, Twist1 and TGFBR2 were detected by real-time PCR. The protein level of Twist1, TGFBR2, collagen Ⅰ, collagen Ⅲ and α-SMA were detected by Western blot. Target regulation of miR-223 on Twist1 and TGFBR2 3'UTR was verified by double luciferase reporter gene system. Results: The average optical density of α-SMA-positive cardiomyocytes in miR-223 group (0.089±0.013) was significantly lower than that in model group and miR-223-NC group (0.134±0.018, 0.132±0.016, respectively). The mRNA level of collagen Ⅰ, collagen Ⅲ, Twist1 and TGFBR2 in miR-223 group were significantly lower than that in model group and miR-223-NC group (all P<0.05). The protein level of Twist1, TGFBR2, collagen Ⅰ, collagen Ⅲ and α-SMA in miR-223 group was significantly lower than model group and miR-223-NC group (all P<0.05). Twist1, TGFBR2 3'UTR wild-type double luciferase reporter plasmids and miR-223 mimics were co-transfected in 293T cells, and luciferase activity was significantly reduced (0.48±0.06 vs 0.92±0.17 and 0.51±0.07 vs 0.94±0.12). Conclusion: MiR-223 may inhibit the activation of fibrosis-related signaling pathway in cardiomyocytes by down-regulating the expression of Twist1 andTGFBR2 genes.

Abstract
BACKGROUND Colorectal cancer (CRC) is the second most common cancer in Malaysia. Awareness of risk factors, symptoms and warning signs of CRC will help in early detection. This paper presents the level of CRC awareness among the urban population in Malaysia. METHOD A cross-sectional study was conducted from November 2015 till December 2016 at three government clinics in the Klang Valley. The validated Bowel Cancer Awareness Measure questionnaire in both English and Malay was used. The mean knowledge scores for the warning signs and risk factors of CRC in different socio-demographic groups were compared using ANOVA in SPSS version 23. Statistical significance was set at p<0.05 and a 95% confidence level. RESULTS Of the 426 respondents, 29.1% were unable to recall the warning signs and symptoms of CRC. Average recall was less than two warning signs and symptoms (mean 1.62, SD 1.33). The mean total knowledge score for CRC was 9.91 (SD 4.78), with a mean knowledge scores for warning signs and risk factors at 5.27 (SD 2.74) and 4.64 (SD 2.78), respectively. Respondents with a higher level of education were found to have higher level of knowledge regarding the warning signs of CRC. There was a significant positive association between knowledge score for warning signs and level of confidence in detecting warning signs. Regarding the total knowledge score for CRC, 3.3% of respondents scored zero. For warning signs and risk factors, 8.2% and 8.5% of respondents had zero knowledge scores, respectively. CONCLUSIONS Generally, awareness of CRC is poor among the urban population of Klang Valley. Greater education and more confidence in detecting warning signs are significantly associated with better knowledge of warning signs. CRC awareness programs should be increased to improve awareness.

Abstract
Objective: To observe the clinical effects of sequential treatment with extensive lesion resection, vacuum sealing drainage (VSD) combined with irrigation of oxygen-loaded fluid, and tissue transplantation on hidradenitis suppurativa (HS) in buttocks which recurred after multiple surgeries. Methods: From January 2012 to March 2017, 15 male patients (aged 26-53 years) hospitalized in our burn ward with Hurley's stage Ⅲ HS in the buttocks recurred after 2-5 operations who met the inclusion criteria were enrolled in the prospective self pre- and post-control study. After extensive resection of the lesion, continuous VSD combined with intermittent irrigation of oxygen-loaded fluid was given, with negative pressure of -16.7 kPa and flow rate of pure oxygen of 1.0 L/min. After 7 days of treatment with VSD combined with irrigation of oxygen-loaded fluid, the negative pressure device was removed and autologous posterior thigh split-thickness skin grafts and/or local flaps were transplanted to repair the wounds. Six patients were performed with split-thickness skin grafting, 4 patients with local flap transplantation, and 5 patients with split-thickness skin grafting together with local flap transplantation. The donor sites of local flaps were sutured directly or transplanted with autologous posterior thigh split-thickness skin grafts, and the donor sites of split-thickness skin grafts with autologous thin split-thickness scalp. The wound tissue or wound granulation tissue was collected before lesion resection and 7 days after treatment with VSD combined with irrigation of oxygen-loaded fluid respectively for bacterial culture and detecting of the content of tumor necrosis factor-alpha (TNF-α) by enzyme-linked immunosorbent assay. Survival of skin grafts and flaps after operation was observed, hospitalization time was recorded, and recurrence and complications of HS were followed up. Data were processed with paired sample t test. Results: Bacterial culture result of wound tissue before lesion resection was positive in all patients, mainly Staphylococcus, Streptococcus, Proteus mirabilis, and anaerobic bacteria, etc., while that of wound granulation tissue after 7 days of treatment with VSD combined with irrigation of oxygen-loaded fluid was negative. The content of TNF-α in wound granulation tissue after 7 days of treatment with VSD combined with irrigation of oxygen-loaded fluid was (10.1±2.9) pg/L, significantly lower than (73.6±5.6) pg/L before lesion resection (t=33.47, P<0.01). The skin grafts and/or flaps of 15 patients survived post operation, and the wounds were healed. The patients were hospitalized for 17-31 days. During follow-up of 1 to 5 years, no recurrence of HS occurred in operative site of buttocks of 15 patients, but 1 patient had ulceration of healed perianal incision caused by high anal fistula and was healed after treatment. Conclusions: Sequential treatment with extensive resection, VSD combined with irrigation of oxygen-loaded fluid, and tissue transplantation can thoroughly remove HS lesions in the buttocks and improve the condition of wound bed for skin acceptance after debridement, which is conducive to the cure of HS in the buttocks which has undergone multiple operations but still recurs after operation.

Abstract
Abstract
Background
New-onset atrial fibrillation (NOAF) complicating acute myocardial infarction (AMI) can be associated with adverse cardiovascular events. The prognostic implication of the burden of atrial fibrillation has been investigated in various settings.
Purpose
We aimed to explore the association of the burden of post-MI NOAF with the risk of adverse cardiovascular events during hospitalization.
Methods
All consecutive patients admitted forAMI between February 2014 and February 2018 were analyzed by continuous electronic monitoring (CEM) through hospitalization. AF burden was calculated by dividing the total AF duration by the total CEM duration. Patients were divided into 3 groups: sinus rhythm group, low burden (AF burden≤8.5%) group, and high burden (AF burden>8.5%) group. The primary outcome was a composite of in-hospital all-cause death, recurrent MI, acute heart failure, or cardiogenic shock.
Results
Overall, 2405 patients (mean age: 65.8 years; male: 76.6%) were included. NOAF was documented in 11.6% of patients, and the primary outcome was recorded in 288 patients (13.6%) of the sinus rhythm group, 42 (30.0%) in the low burden group, and 71 (50.7%) in the high burden group. Compared with patients with sinus rhythm, a greater burden of NOAF was associated with a higher risk of the primary outcome after multivariable analysis (low burden: hazard ratio, 1.22; 95% confidence interval [CI]: 0.87–1.70; high burden: hazard ratio, 1.90; 95% CI: 1.43–2.51; p for trend<0.001).

Abstract
Objective: To investigate the relationship between single nucleotide polymorphism(SNP) of vitamin D receptor(VDR) gene with susceptibility to allergic rhinitis(AR). Method: Two hundred and ten AR patients were selected as AR group, and 180 healthy volunteers from the same period were selected as control group. Fasting venous blood was collected from all subjects and blood DNA was extracted. Polymorphisms at ApaⅠ(rs7975232) and FokⅠ(rs2228570) loci of VDR gene were detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP), and the relationships between different genotypes with susceptibility to AR were comparatively analyzed. The Hardy-Weinberg's law of genetic balance verifies whether the two genotype frequencies were representative; Logistic multiple regression analysis was used to analyze the related factors affecting susceptibility of AR. Result: There were SNPs at rs7975232 locus of VDR gene, which were wild homozygote CC type, mutant heterozygote AC, and mutant homozygote AA. SNPs existed at rs2228570 locus, which were wild homozygote GG, mutant heterozygote GA, and mutant homozygote AA. The distributions of genotypes at rs7975232 and rs2228570 locus of VDR gene conformed to Hardy-Weinberg law. There was a significant difference in the distribution of rs7975232 genotype(P<0.05), and the frequency of C allele in the study group was significantly higher than that in the control group(P<0.05). There was no significant difference in genotype distribution of rs2228570 locus (P>0.05). Logistic analysis showed that CC genotype of ApaⅠwas a risk factor for AR susceptibility. Conclusion: The polymorphism of ApaⅠ(rs7975232) locus of VDR gene is correlated with AR susceptibility. CC genotype may be a susceptible factor for AR patients, but there is no significant correlation between FokⅠ polymorphism and AR. .

Abstract
Objective: To investigate the expression and interaction of VHL/HIF-α pathways including HIF-1α, HIF-2α as well as VHL in erythroid progenitor cells of bone marrow from chronic mountain sickness (CMS) patients. Methods: A total of 25 patients with CMS and 21 healthy controls were recruited for this study. The CD71(+)CD235a(+) cells in bone marrow mononuclear cells, marked as erythroid progenitor cells, were isolated using MACS separation technology. The expression levels of HIF-1α, HIF-2α and VHL in erythroid progenitor cells were detected by Western blotting and real-time fluorescence quantitative PCR. Results: The mRNA levels of HIF-2α were higher in erythroid progenitor cells of CMS than in healthy controls [1.68 (0.81, 2.22) vs 0.98 (0.60, 1.19), P<0.05], while HIF-1α and VHL mRNA levels were similar between the two groups (P>0.05). Spearman analyses indicated that HIF-2α mRNA was positively associated with hemoglobin (Hb) levels in the erythroid progenitor cells of CMS (ρ=0.504, P<0.05). Furthermore, the mRNA level of HIF-2α was correlated with the mRNA level of VHL in the erythroid progenitor cells of CMS (ρ=0.647, P<0.05).The protein levels of HIF-2α in the erythroid progenitor cells of CMS were higher than that of healthy controls [0.94(0.68, 3.30) vs 0.59(0.30, 0.88), P<0.05], but the protein levels of HIF-1α and VHL were similar between the two groups (P>0.05). Conclusions: The abnormal increased expression of HIF-2α in the erythroid progenitor cells of CMS patients leads to the abnormal expression of hypoxia sensitive genes downstream, participating in the occurrence and development of CMS.

Abstract
Automatic myocardial infarction (MI) detection using an electrocardiogram (ECG) is of great significance for improving the survival rate of patients. In this study, we propose a multi-lead ensemble neural network (MENN) to distinguish anterior myocardial infarction (AMI) and inferior myocardial infarction (IMI) from healthy control (HC) respectively. In the study, three kinds of sub-networks and multi-lead ECG signals are combined, which fully explores the information of ECG signals and improves the classification performance. The algorithm is evaluated on the PTB database by 5-fold inter-subject cross-validation and the sensitivity (Se), specificity (Sp) and area under the curve (AUC) of AMI detection are 98.35%, 97.49%, 97.92%; The Se, Sp, and AUC of IMI detection are 93.17%, 92.02%, 92.60%. The proposed method achieves the state of the art results on both tasks and outperforms the baseline methods. Hence, the proposed method is potential for automatic MI diagnosis.

Abstract
Dioxins, polybrominated diphenyl ethers, and benzo(a)pyrene are common organic pollutants in food. They have been of concern to academics and government administrations due to high residue and persistence, easy accumulation and strong harmful effects. The National Research Council of the United States of America published Toxicity Testing in the 21st Century: A Vision and Strategy in 2007, which proposed a new concept of toxicity testing that toxicity testing should take full consideration of population exposure data and base on in vitro tests, human cell lines, toxicity pathways and high-throughput screening. Meanwhile, systems biology, bioinformatics and rapid assay technologies will be used to better understand toxicity pathways-the cellular response pathways that can lead to adverse health effects when sufficient perturbing induced by chemicals exposure. The new toxicity testing strategy has changed the traditional testing pattern and has brought a wide impact on the international relevant fields. The European Union, the World Health Organization, and the United States Environmental Protection Agency, the Food and Drug Administration, and the National Center for Toxicological Research have organized relevant discussions and exploratory studies to address the new toxicity testing concept and how to evaluate and utilize the results of traditional toxicity test researches. Compared to the discussion, 'whether to do it', ten years ago, the question, 'how to do it', has become the concern of the current discussion. Therefore, how to respond to the concept of toxicity testing and how to effectively utilize and excavate traditional toxicity test data have been the focus of multi-disciplines and interdisciplinary academia such as toxicology, food hygiene and environmental science. Therefore, this article provides an overview of the exposure levels of dioxin, polybrominated diphenyl ethers and benzo[a]pyrene, which are typical persistent organic pollutants in food in China and the current research status of toxic pathways based on whole animal experiments. The exposure level, toxic effect and toxicity mechanism of three contaminants are analyzed and summarized in order to provide basis for future results based on the 21st century toxicity test compared with traditional tests and data mining analysis of these two kinds of data. Meanwhile, it also lays the foundation for the establishment of a toxicity testing framework based on exposure characteristics, toxic pathways, and biomarkers.

Abstract
Objective: To assess the values of pelvic contrast enhanced magnetic resonance angiography (MRA) in detection of prostatic artery prior to prostatic arterial embolization(PAE). Methods: This multicenter, prospective study from 5 hospitals in China consisted of 47 patients (mean age (69±16) years, range 56-83 years) who underwent PAE for benign prostatic hyperplasia (BPH) between January 2016 and April 2018, preprocedural prediction of prostatic arteries were determined using contrast enhanced MRA.CE-MRA findings were compared with subsequent intraprocedural digital subtraction angiography (DSA) or DSA combined with cone-beam computed tomography (CT) to assess the sensitivity and specificity with which contrast enhanced MRA predicted the number and origins of prostatic artery, also to assess the optimal oblique projection of PA. Results: In total, 47 patients (94 pelvic sides) with 97 PAs confirmed by DSA or DSA combined with cone-beam CT at the time of embolization, MR angiography successfully identified 88 PAs and their origins , the sensitivity and specificity was 90.7% (88/97) and 93.6% (88/94), respectively.MR angiography correctly determined the bilateral prostatic artery origins in 36 (76.6%) cases.According to the optimal oblique projection of PAs suggested by MR angiography, the origins and trajectory of PAs of all patients underwent PAE with the same oblique projection (20°-45°ipsilateral anterior oblique direction) were clearly displayed when performed the first arteriography. Conclusion: Pelvic contrast enhanced MR angiography with high sensitivity and specificity in detection the origin, trajectory and number of PAs, and it could provide useful information regarding prostatic arteries before PAE.

Abstract
Objective: To explore postoperative delirium (POD)risk factors for geriatric patients who suffered hip fracture under the care of orthogeriatric unit mode. Methods: Patients aged 65 years or older, who were admitted to the orthogeriatric unit in Beijing Jishuitan Hospital from April to October 2017 for hip fracture surgery, were eligible for this prospective cohort study. After univariable analysis, significant risk factors associated with POD were further evaluated with multivariable analysis, to establish independent risk factors associated with POD. Results: A total of 203 patients with an average age of 80(65-96)years were enrolled in the study. The overall incidence of POD was 9.4%(19/203)in which hyperactive and hypoactive type accounting for 84.2%(16/19)and 15.8%(3/19), respectively. Significant difference was found between POD and non-POD groups in patients' age (P=0.003), albumin(P=0.006), TSH(P=0.018), PaCO(2) level(P=0.003), visual analogue scale (VAS )both at rest (P=0.013)and movement(P=0.010) on post-operative day 1.The further Logistic stepwise regression analysis showed that significant differences existed between groups in age(P=0.027), albumin(P=0.003), PaCO(2)(P=0.014)and VAS at rest(P=0.002). Conclusion: The independent risk factors of POD in geriatric patients undergoing hip fracture under the orthogeriatric unit mode include patients' age, pre-operative albumin as well as PaCO(2) level and post-operative VAS at rest.

Abstract
Objective: To explore the biomarkers that applied to pulmonary acute respiratory distress syndrome (ARDS) and extrapulmonary ARDS respectively. Methods: A total of 49 eligible patients with ARDS were selected from Department of Respiratory intensive care unite (ICU) , Department of General ICU and Department of Emergency ICU, the Second Affiliated Hospital of Nanchang University, during April 2015 and February 2016, and divided into pulmonary ARDS group (n=26) and extrapulmonary ARDS group (n=23) according to primary causes. Totally 19 cases from healthy examination personnel were served as control. Acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ) score and lung injury score of all hospitalized patients were completed within 24 hours after the diagnosis of ARDS and the serum levels of angiogenin2 (Ang-2) , surfactant protein D (SP-D), soluble receptor for advanced glycation end products (sRAGE), Krebs von den Lungen-6 (KL-6) were measured. Then the 28-day outcomes were observed. The serum levels of the biomarkers were compared between each group and correlation analysis was conducted between different indexes. Finally, The relationship between the four biomarkers and the outcome of each group was analyzed. Results: The serum level of Ang-2 in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[1 462 (569, 3 638) and 4 568 (2 236, 8 457) vs 460 (389, 578) ng/L, all P<0.05], and the serum level of Ang-2 was significantly higher in extrapulmonary ARDS group than that in pulmonary ARDS group (P<0.05). The serum level of SP-D in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[5.9 (2.5, 22.7) mg/L and 3.7 (1.7, 6.5) vs 1.9 (0.6, 4.4) mg/L, all P<0.05], and the serum level of SP-D was significantly higher in pulmonary ARDS group than that in extrapulmonary ARDS group (P<0.05). The serum level of sRAGE in pulmonary ARDS group and extrapulmonary ARDS group was significantly higher than that in control group[238 (101, 583) and 229 (114, 443) vs 117 (88, 176) ng/L, all P<0.05]. The serum level of KL-6 in pulmonary ARDS group was significantly higher than that in control group[10 435 (3 401, 17 607) vs 4 780 (3 962, 5 320) U/L, P<0.05]. Increased serum levels of SP-D (OR=1.089, 95% CI: 1.001-1.085) and KL-6 (OR=1.206, 95% CI: 1.016-1.432) at the early stage were the independent prognostic factors for the 28-day mortality for pulmonary ARDS. Advanced age (OR=2.622, 95% CI: 1.046-6.574) was the independent prognostic factor for the 28-day mortality for extrapulmonary ARDS. Conclusion: SP-D and KL-6 may be the serum biomarkers of pulmonary ARDS and Ang-2 may be the serum biomarker of extrapulmonary ARDS.

Abstract
The aim of this study was to evaluate the effects of antibiotic residues in milk on growth, ruminal fermentation, and microbial community of dairy calves in their first 35 d of age. Twenty newborn Holstein bull calves were assigned to 1 of 2 treatments equally: milk replacer without antibiotics (control) and milk replacer plus 4 antibiotics: 0.024 mg/L of penicillin, 0.025 mg/L of streptomycin, 0.1 mg/L of tetracycline, and 0.33 mg/L of ceftiofur (ANT). Starter intake and fecal consistency scores of each calf were recorded on a daily basis. Body weight, withers height, body length, and heart girth were measured on d 1, 7, 14, 21, 28, and 35 before feeding in the morning. Rumen fluid was collected on d 15, 25, and 35 to determine ruminal pH, volatile fatty acids (VFA), and NH3-N concentrations. A total of 10 (5 per treatment) samples of rumen fluid taken on d 35 were analyzed for microbial community. Rumen tissues from the cranial ventral sac and cranial dorsal sac were collected from 8 calves of each group for morphology analysis on d 35 after being harvested. The results showed that calves in 2 treatments had similar starter intake, body weight, withers height, body length, heart girth, and average daily gain. The ANT group showed a lower diarrhea frequency in wk 4, and no differences were found for other weeks. Calves in the ANT group exhibited a greater concentration of acetic acid in the rumen and no differences for other VFA, total VFA, rumen pH, or NH3-N. As for rumen morphology, the length of papillae from cranial ventral sac of the ANT group was longer than that of the control group. The results of ruminal microbial community showed that antibiotic residues had minor effects on bacteria phyla and bacteria diversity. At the genus level, calves in the ANT group showed lower richness of Prevotella and higher richness of Acetitomaculum. In conclusion, antibiotic residues stimulated the development of ruminal papillae and increased the production of acetic acid in rumen, which might be caused by the influence of antibiotics on the ruminal microbial community.

Abstract
Objective: To observe the effects of the method of combining free superficial temporal fascia flaps with skin grafts in repairing deep wounds in posterior ankle region of extensively burned patients. Methods: From September 2013 to February 2017, 11 extensively burned patients with deep tissue defects in posterior ankle region were treated in our unit. Two patients had tissue defects in bilateral posterior ankle regions. The wound sizes ranged from 5.8 cm×4.6 cm to 11.7 cm×5.2 cm. Free superficial temporal fascia flaps with the same sizes as the wounds were designed and resected to repair wounds in posterior ankle regions after debridement. The proximal end of superficial temporal veins and posterior tibial veins were performed with end-to-end anastomosis, and superficial temporal arteries and posterior tibial arteries were performed with end-to-side anastomosis. Skin grafts were resected to cover the superficial temporal fascia flaps according to patients' condition of donor sites. The donor sites were sutured directly. Results: All fascial flaps in 11 patients survived, while 2 skin grafts had partial necrosis, and they healed after secondary skin graft. All patients were followed up for 6 to 13 months, and the shape and function of the operation sites in all patients recovered well. Conclusions: The method of combining free superficial temporal fascia flaps with skin grafts can repair deep wounds in posterior ankle regions of extensively burned patients. It has the advantages of good appearances in the recipient sites, strong resistances to infection of fascia flaps, minimal damages to the donor sites, short course of disease, and good prognosis of patients.

Abstract
BACKGROUND Previous studies suggest that dexmedetomidine has a protective effect against local anaesthetic-induced nerve injury in regional nerve blocks. Whether this potentially protective effect exists in the context of diabetes mellitus is unknown. METHODS A diabetic state was established in adult male Sprague-Dawley rats with intraperitoneal injection of streptozotocin. Injections of ropivacaine 0.5%, dexmedetomidine 20 μg kg-1 (alone and in combination), or normal saline (all in 0.2 ml) were made around the sciatic nerve in control and diabetic rats (n=8 per group). The duration of sensory and motor nerve block and the motor nerve conduction velocity (MNCV) were determined. Sciatic nerves were harvested at post-injection day 7 and assessed with light and electron microscopy or used for pro-inflammatory cytokine measurements. RESULTS Ropivacaine and dexmedetomidine alone or in combination did not produce nerve fibre damage in control non-diabetic rats. In diabetic rats, ropivacaine induced significant nerve fibre damage, which was enhanced by dexmedetomidine. This manifested with slowed MNCV, decreased axon density, and decreased ratio of inner to outer diameter of the myelin sheath (G ratio). Demyelination, axon disappearance, and empty vacuoles were also found using electron microscopy. An associated increase in nerve interleukin-1β and tumour necrosis factor-α was also seen. CONCLUSIONS Ropivacaine 0.5% causes significant sciatic nerve injury in diabetic rats that is greatly potentiated by high-dose dexmedetomidine. Although the dose of dexmedetomidine used in this study is considerably higher than that used in clinical practice, our data suggest that further studies to assess ropivacaine (alone and in combination with dexmedetomidine) use for peripheral nerve blockade in diabetic patients are warranted.

Abstract
The safety assessment of nanomaterials in food is essential for safeguarding supervision and maintaining public health. However, there are still no safety assessment procedures for nanomaterials established in national-level in China and no specific toxicology and safety assessment procedures about nanomaterials for food, too. These factors lead to restriction on food safety protection and supervision. Current methods of evaluating the safety of nanomaterials mainly rely on traditional toxicological assessment that are extrapolated based on animal experiment from high doses to low doses and from animals to humans. These uncertainties restrict the accuracy of safety assessment for nanomaterials and also limit the development of scientific and effective evaluation procedures and regulatory measures. Currently, the key issues need to be solved including exposure assessment and evaluation methods of nanomaterials in food and the established methods of the toxicity test for nanomaterials that are consistent with the objectives of toxicity test in the 21st century vision and strategy. In this article, we reviewed current administrative regulatory, situations, and existing issues of food nanomaterials either in China or some developed countries in order to provide a scientific basis in establishing safety assessment procedures for nanomaterials in food in the future.

Abstract
Objective: To explore the relation between platelet-to-lymphocyte ratio (PLR) or neutrophil-to-lymphocyte ratio (NLR) with disease activity in Takayasu arteritis (TA) patients. Methods: Present retrospective study involved 289 patients with TA, who were hospitalized in our department between January 2010 and October 2017, and 280 age and gender matched healthy controls,who underwent thealth examination in our health examination center during the same period (control group). TA patients were further divided into active and inactive groups (180 and 109 cases respectively) according to Kerr scores. The clinical data were compared between groups. Pearson correlation analysis was used to evaluate the relationship between PLR or NLR and disease activity (Kerr score or C-reactive protein or erythrocyte sedimentation rate). Receiver operating characteristic (ROC) curve was employed to judge the cut-off value of disease activity for TA patients. Results: PLR and NLR were significantly higher in TA group than in control group(137.33 (97.38, 193.37) vs. 120.55 (96.86, 144.60) and 2.38 (1.76, 3.57) vs. 1.66 (1.35, 2.08) , respectively, all P<0.001). PLR and NLR were significantly higher in active TA group than in inactive TA group (163.43 (123.64, 224.15) vs. 110.53 (84.22, 147.24) and 2.59 (1.96, 3.94) vs. 1.95 (1.53, 2.86) respectively, all P<0.001). PLR and NLR of active group were significantly decreased after 6 months treatment (164.05 (123.29, 226.29) vs. 104.67 (77.22, 138.43) and 2.58 (1.96, 3.91) vs. 2.15 (1.67, 2.60) respectively, all P<0.001). PLR was positively correlated with Kerr score (r=0.439, P<0.001), C-reactive protein (r=0.328, P<0.001) and erythrocyte sedimentation rate (r=0.410, P<0.001). NLR also exhibited a positive relationship with Kerr score (r=0.235, P<0.001), C-reactive protein (r=0.169, P=0.005) and erythrocyte sedimentation rate (r=0.123, P=0.037). A PLR level of 176.709 was shown to be the best predictive cut-off value for TA disease activity (sensitivity 44.6%, specificity 93.0%, and area under the curve=0.766).A NLR level of 2.128 was shown to be the best predictive cut-off value for TA disease activity (sensitivity 70.9%, specificity 47.7%, and area under the curve=0.691). Conclusion: PLR and NLR are useful markers for predicting disease activity of TA patients.

Abstract
Objective: This study was aimed at investigating the levels and relationships of vascular endothelial growth factor (VEGF) and its receptor(VEGFR) in the bone marrow mononuclear cells (MNC) of chronic mountain sickness (CMS). Methods: A total of 34 patients with CMS and 30 controls residing at altitudes of 3 000-4 500 m were recruited for this study. The levels of VEGF, VEGFR1 and VEGFR2 in bone marrow MNC were detected by flow cytometry technique and RT-qPCR. Results: The percentage of VEGFR2 positive cells in the bone marrow MNC of CMS were higher than that of the controls[20.7% (8.1%, 67.6%) vs 8.1% (2.2%, 14.9%), P<0.05], but that of VEGFR1-positive and VEGF-positive were similar in CMS and controls. The mRNA levels of VEGFR2 were higher in the bone marrow MNC of CMS than in the controls[1.7(1.0, 5.1) vs 1.0(0.4, 2.7), P<0.05], while VEGF and VEGFR1 mRNA levels were similar between the two groups. The percentage of VEGFR2 positive cells in CMS were significantly correlated with hemoglobin (r=0.453, P=0.007) and the percentage of VEGF-positive cells (r=0.373, P=0.030). Conclusions: Bone marrow MNC of CMS may show enhanced activity of the VEGF-VEGFR2 pathway, and it appears to be involved in the pathogenesis of CMS.

Abstract
The sex pheromones of Ectropis grisescens Warren and Ectropis obliqua Prout were both reported to contain (Z,Z,Z)-3,6,9-octadecatriene (Z3,Z6,Z9-18:H) and (Z,Z)-3,9-cis-6,7-epoxy-octadecadiene (Z3,epo6,Z9-18:H). To clarify how these two sibling geometrids maintain premating isolation, the female sex pheromones of the two species were reexamined. Gas chromatography-electroantennographic detection (GC-EAD) and gas chromatography-mass spectrometry revealed two GC-EAD-active compounds, Z3,Z6,Z9-18:H and Z3,epo6,Z9-18:H, in E. grisescens female pheromone glands as well as an additional GC-EAD-active compound, (Z,Z)-3,9-cis-6,7-epoxy-nonadecadiene (Z3,epo6,Z9-19:H), in E. obliqua female pheromone glands. Synthesized Z3,Z6,Z9-18:H and Z3,epo6,Z9-18:H elicited dose-dependent electroantennogram (EAG) responses from male antennae of both E. grisescens and E. obliqua. However, Z3,epo6,Z9-19:H only elicited dose-dependent EAG responses from E. obliqua and limited EAG responses from E. grisescens at all doses. In wind-tunnel studies, lures that contained Z3,Z6,Z9-18:H and Z3,epo6,Z9-18:H attracted E. grisescens males and had no effect on E. obliqua males. The addition of Z3,epo6,Z9-19:H to the blend of Z3,Z6,Z9-18:H and Z3,epo6,Z9-18:H strongly attracted E. obliqua males but had a limited attraction for E. grisescens males. Thus, Z3,Z6,Z9-18:H and Z3,epo6,Z9-18:H were sex pheromone components of E. grisescens, whereas Z3,Z6,Z9-18:H, Z3,epo6,Z9-18:H and Z3,epo6,Z9-19:H were sex pheromone components of E. obliqua. The presence or absence of Z3,epo6,Z9-19:H played a central role in the premating isolation of these two sibling species.

Abstract
Objective: To study the clinicopathologic features of plasma cell myeloma(PCM) with bone marrow fibrosis (MF). Methods: The clinicopathologic data of 175 cases of newly diagnosed PCM patients were retrospectively analyzed. Based on reticular fiber staining, these cases were divided into PCM-MF and non-PCM-MF groups. Results: Sixty-three cases were PCM-MF(36%), 112 were non-PCM-MF (64%). No statistical difference in gender, age, hemoglobin level, platelet counts, the classification of immunoglobulin, ISS staging, immunohistochemical phenotypes and genetic features was found between PCM-MF and non-PCM-MF groups (P>0.05). Compared to non-PCM-MF group, lactate dehydrogenase (LDH)level and renal impairmentrate were higher in PCM-MF group (P<0.05). The degree of bone marrow hyperplasia, the percentage of myeloma cells and cells with plasmablastic morphology were significantly higher in PCM-MF group(P<0.05). Conclusion: The higher LDH level, renal impairment rate, and more significant bone marrow hyperplasia, proliferation of plasma cells and plasmablastic myeloma cells infiltration indicate poor prognosis of PCM-MF patients.

Abstract
OBJECTIVE To prepare felodipine/copovidone solid dispersions, which were made based on different preparation technologies. Insoluble felodipine was selected as the model drug in this research. This drug belonged to Biopharmaceutics Classification System II (BCSII) with insoluble property and good permeability across intestinal mucosa simultaneously. A comparative study was carried out for further investigating their corresponding pharmaceutical properties. METHODS Felodipine/copovidone solid dispersions were achieved by four methods including spray-drying method, microwave-induced fusion quench cooling method, freeze-drying method and co-precipitation method. These solid dispersions were produced based on corresponding processes that corresponded to these methods. Internal properties of co-povidone solid dispersions were analyzed by various approaches including scanning electron microscope (SEM), differential scanning calorimetry (DSC) and powder X-ray diffraction (PXRD). The improvement on insoluble properties of felodipine by solid dispersions produced by different technologies was characterized by dissolution experiments based on dissolution instrument. Crystallization inhibition effect of polymers against drugs was studied by supersaturated experiments through determining the concentration value at different time points. RESULTS The internal drug was dispersed in amorphous form in solid dispersions produced by spray-drying, microwave method, microwave/quench-cooling method and co-precipitation method. Freeze-drying method resulted in a form of crystal in felodipine/copovidone solid dispersions. Compared with other technologies, microwave-induced quench cooling method could significantly improve the dissolution of insoluble drug felodipine (P<0.05). The dissolution concentration reached approximately 4.65 mg/L at 60 min time point. Copovidone could inhibit or retard the crystallization of felodipine in a supersaturated state. In the solution pre-dissolved with maximum copoyidone polymer, the minimum crystallization rate of supersaturated felodipine was observed at 240 min time point. The value of crystallization rate was 0.19 mg/(L×min). CONCLUSION The study is helpful to understand and clarify the internal properties of solid dispersions obtained by different technologies. The research also provides beneficial consultation for the choice of technology in practical production of drug-polymer solid dispersions.

Abstract
Objective: To characterize the clinic features of fulminant type 1 diabetes mellitus(FT1DM). Methods: It was a retrospective study analyzing the clinical and laboratory data of patients diagnosed as FT1DM and type 1 diabetes in the Department of Endocrinology in China-Japan Friendship Hospital from January 2011 to November 2015. Results: A total of 125 newly diagnosed type 1 diabetic patients were included in the study, 14 of them (11.2%) met with the criteria of FT1DM. The age at onset was (35.8±8.3) years. The time from onset to ketosis was 2(0-7) days. The plasma glucose levels were extremely high[ (33.79±14.13)mmol/L], while glycosylated hemoglobin A1c[HbA1c, (6.9±0.7) %]and serum glycosylated albumin [(21.8±4.5)%] levels were only slightly above the normal range. Moreover, the C-peptide levels were extremely low and the situation kept after one month to two years' follow-up. Four (28%) patients were glutamic acid decarboxylase antibody (GADA) positive at the onset with two turned negative. One patient was GADA negative at the onset and turned positive after one month. The levels of serum transaminases increased with enlargement of liver in one of the patients after insulin therapy, who was diagnosed as glycogenic hepatopathy. Conclusions: FT1DM is an extremely rapidly progressing type of diabetes and life threatening disease. Causations have to be taken in medical practice.

Abstract
OBJECTIVE To verify the safety and efficacy of the domestic 3D cardiac electrophysiological mapping system for catheter ablation of persistent atrial fibrillation (AF). METHODS From December 2011 to April 2014, 255 patients (184 male) with persistent AF in 13 centers were enrolled in this multicenter prospective controlled study.The patients were allocated to catheter ablation group (experiment group) and antiarrhythmics drugs cardioversion group (control group) with the ratio 2∶1 according to the patients' intention. Left atria were constructed with 3D cardiac electrophysiology mapping system, magnetic sensored saline irrigated radiofrequency ablation catheter (FireMagic™ Cool 3D) and surface reference (Columbus™). Pulmonary vein isolation and left atrial roof line, mitral annulus isthmus line, three tricuspid annulus isthmus line, superior vena cava, the coronary sinus and complex atrial fragmented potentials were targeted if necessary under the guidance of the 3D mapping system. Antiarrhythmics drugs (except amiodarone) were applied to patients for 2 to 3 months after ablation. The patients were followed up for 9 months after 3 months blanking period. The patients in the control group underwent cardioversion with amiodarone and electrical cardioversion if needed. Patients in the control group were also followed up for 9 months. RESULTS Of the 255 patients, 167 cases were in the experiment group and 88 cases were in the control group. In per protocol set (PPS), 155 cases were in the experiment group, 79 cases in the control group. Catheter ablation was successful for all patients in the experiment group under the guidance of the 3D cardiac electrophysiological mapping system. Pumononary veins isolation was achieved in all patients. After 9 months follow-up beyond blanking period, in full analysis set, the success rate was 66.5% (111/167) in the experiment group, which was significantly higher than that in the control group (21.6% (19/88), P<0.001). In PPS, the success rate was also significantly higher in the experiment group than in the control group (67.1% (104/155) vs. 22.8%(18/79), P<0.001). The incidence of adverse events was 19.8% in the experiment group and 13.6% in the control group(P=0.223). The adverse events associated with catheter ablation included 1 case of left subclavian hematoma, 1 case of left subclavian bleeding and 1 case of pericardial effusion, which was alleviated by pericardiocentesis. No pulmonary vein stenosis occurred. CONCLUSION Domestic 3D cardiac electrophysiological mapping system can safely and effectively guide catheter ablation of persistent AF.

Abstract
We studied the magneto-optical response of a canonical topological insulator Bi2Se3 with the goal of addressing a controversial issue of electron-phonon coupling. Magnetic-field induced modifications of reflectance are very pronounced in the infrared part of the spectrum, indicating strong electron-phonon coupling. This coupling causes an asymmetric line-shape of the 60 cm(-1) phonon mode, and is analyzed within the Fano formalism. The analysis reveals that the Fano asymmetry parameter (q) changes sign when the cyclotron resonance is degenerate with the phonon mode. To the best of our knowledge this is the first example of magnetic field driven q-reversal.

Abstract
Two pairs of positive-and negative-parity doublet bands together with eight strong electric dipole transitions linking their yrast positive- and negative-parity bands have been identified in ^{78}Br. They are interpreted as multiple chiral doublet bands with octupole correlations, which is supported by the microscopic multidimensionally-constrained covariant density functional theory and triaxial particle rotor model calculations. This observation reports the first example of chiral geometry in octupole soft nuclei.
