Objective:To investigate the clinical efficacy of radical resection of rectal cancer with different surgical approaches and influencing factors of postoperative complications.Methods:The retrospective study was conducted. The clinicopathological data of 3 418 patients who underwent radical resection of rectal cancer in the Second Affiliated Hospital of Harbin Medical University from July 2011 to September 2020 were collected. There were 2 060 males and 1 358 females, aged (61±11)years. Patients meeting the requirements of radical resection and surgical indications underwent surgeries choosing from open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery, and natural orifice specimen extraction surgery (NOSES). Observation indicators: (1) intraoperative and postoperative conditions of patients undergoing different surgical approaches; (2) comparison of preoperative clinical characteristics in patients undergoing different surgical approaches; (3) comparison of postoperative histopathological characteristics in patients undergoing different surgical approaches; (4) postoperative complications of patients undergoing different surgical approaches; (5) analysis of influencing factors of postoperative complications. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range), and comparisons between groups was analyzed using the Kruskal-Wallis rank test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Multivariate analysis was conducted using the Logistic regression model. Results:(1) Intraoperative and postoperative conditions of patients undergoing different surgical approaches. Of the 3 418 patients, 1 978 cases underwent open radical colorectal cancer sur-gery, 1 028 cases underwent laparoscopic radical colorectal cancer surgery and 412 cases underwent NOSES, respectively. The operation time, volume of intraoperative blood loss, cases with permanent stoma, preventive stoma or without fistula, time to postoperative first flatus, time to postoperative liquid food intake, cases transferred to intensive care unit after surgery, duration of postoperative hospital stay were 145(range, 55?460)minutes, 100(range, 30?1 000)mL, 435, 88, 1 455, 72(range, 10?220)hours, 96(range, 16?296)hours, 158, 10(range, 6?60)days, respectively, in patients undergoing open radical colorectal cancer surgery.

(2) Com-parison of preoperative clinical characteristics in patients undergoing different surgical approaches. The gender, age, body mass index, cases with diabetes, cases with hypertension, cases with coronary heart disease, cases with anemia, cases with hypoproteinemia, cases with intestinal obstruction, tumor location, preoperative carcinoembryonic antigen, preoperative CA19-9 showed significant differences among patients undergoing open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery and NOSES ( P<0.05). (3) Comparison of postoperative histopathological characteris-tics in patients undergoing different surgical approaches. Tumor histological type, tumor differentiation degree, tumor diameter, number of lymph node detected, nerve invasion, vascular invasion, lymph node invasion, tumor T staging, tumor N staging, tumor M staging, tumor TNM staging showed significant differences among patients undergoing open radical colorectal cancer surgery, laparos-copic radical colorectal cancer surgery and NOSES ( P<0.05). (4) Postoperative complications of patients undergoing different surgical approaches. Cases with postoperative complications as anastomotic leakage, abdominal infection, intestinal obstruction, anastomotic bleeding, incision complications, pulmonary infection, other complications were 52, 21, 309, 8, 130, 51, 59, respectively, in patients undergoing open radical colorectal cancer surgery. The above indicators were 33, 17, 75, 3, 45, 58, 9, respectively, in patients undergoing laparoscopic radical colorectal cancer surgery and 13, 4, 8, 0, 11, 10, 15, respectively, in patients undergoing NOSES. There were significant differences in the intes-tinal obstruction, incision complications, pulmonary infection, other complications among patients undergoing different surgical approaches ( χ2=122.56, 13.33, 20.44, 15.59, P<0.05) and there was no significant difference in the anastomotic leakage, abdominal infection, anastomotic bleeding among patients undergoing different surgical approaches ( χ2=0.96, 2.21, 3.08, P>0.05). (5) Analysis of influencing factors of postoperative complications. ① Analysis of influencing factors of intestinal obstruction in patients with radical resection of rectal cancer. Age as 20?39 years and 40?59 years, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of intestinal obstruction in patients with radical resection of rectal cancer ( odds ratio=0.46, 0.59, 0.43, 0.13, 95% confidence interval as 0.21?1.00, 0.36?0.96, 0.33?0.56, 0.06?0.27, P<0.05). ② Analysis of influencing factors of incision complications in patients with radical resection of rectal cancer. Body mass index as 24.0?26.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of incision complications in patients with radical resection of rectal cancer ( odds ratio=0.24, 0.63, 0.46, 95% confidence interval as 0.11?0.51, 0.44?0.89, 0.24?0.87, P<0.05). ③ Analysis of influencing factors of pulmonary infection in patients with radical resection of rectal cancer. The surgical approach as laparoscopic radical colorectal cancer surgery was an independent risk factor of pulmonary infection in patients with radical resection of rectal cancer ( odds ratio=2.15, 95% confidence interval as 1.46?3.18, P<0.05), and tumor TNM staging as 0?Ⅰ stage was an independent protective factor ( odds ratio=0.10, 95% confidence interval as 0.01?0.88, P<0.05). ④ Analysis of influencing factors of other complica-tions in patients with radical resection of rectal cancer. Age as 20?39 years, 40?59 years, 60?79 years, body mass index as <18.5 kg/m 2, 18.5?23.9 kg/m 2, 24.0?26.9 kg/m 2, 27.0?29.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery were independent protective factors of other complications in patients with radical resection of rectal cancer ( odds ratio=0.10, 0.29, 0.37, 0.08, 0.22, 0.35, 0.32, 0.29, 95% confidence interval as 0.01?0.81, 0.13?0.64, 0.17?0.78, 0.02?0.40, 0.09?0.52, 0.15?0.83, 0.12?0.89, 0.14?0.59, P<0.05). Conclusions:Compared to laparoscopic radical colorectal cancer surgery and NOSES, open radical colorectal cancer surgery has wide indication and short operation time, but less perioperative treatment effect. Laparoscopic radical colorectal cancer surgery and NOSES can achieve better surgical result and less postoperative complication when patients meeting surgical indications.

AIM: To assess the bioequivalence of oral dexamethasone acetate tablets between the test and reference formulations in healthy adult Chinese subjects on an empty stomach and after meals. METHODS: A randomized, open, single-dose, two-cycle double crossover bioequivalence study was followed. Twenty-four healthy subjects were included in the fasting group, and 32 healthy subjects were included in the postprandial group, taking 2 tablets (0.75 mg/tablet) of the test formulation (T) or 3 tablets (0.50 mg/tablet) of the reference formulation (R) per cycle for two cycles. The concentrations of dexamethasone acetate in human plasma were determined using liquid chromatography-mass spectrometry, and the pharmacokinetic parameters were calculated according to the non-atrial model using WinNonlin 8.0 software.The bioequivalence of both the test formulation and the reference formulation was evaluated. RESULTS: The pharmacokinetic parameters after oral administration of dexamethasone acetate tablets in a fasted state in subjects with the reference formulation are as follows: Tmax 1.13 (0.50, 4.00) and 1.00 (0.50, 5.00) h, AUC0-t (72.25±21.55) and (69.23±17.76) ng · mL

OBJECTIVE: To assess the association of 7 single nucleotide polymorphisms (SNPs) including rs13278062 (TNFRSF10A), rs3750846 (ARMS2-HTRA1), rs429358 (APOE), rs5817082 (CEPT), rs2043085 (LIPC), rs1626340 (TGFBR1), and rs8135665 (SLC16A8) identified through genome-wide association study (GWAS) with age-related macular degeneration (AMD) among ethnic Han Chinese from Sichuan, China. METHODS: A cohort of 576 AMD patients and 572 healthy controls were enrolled in a case-control study. The SNPs were genotyped by a Mass array MALDI-TOF System. On the premise that the genotype distribution of each SNP locus in both groups satisfied Hardy-Weinberg equilibrium, the genetic pattern was analyzed and the scores of allele and genotype frequencies ware compared. RESULTS: There was a significant association between TNFRSF10A rs13278062 and AMD under the heterozygous model (P = 0.000, OR = 1.529, 95%CI = 1.196-1.954) and the dominant model (P = 0.002, OR = 1.459, 95%CI = 1.154-1.865), suggesting that subjects carrying rs13278062GT and rs13278062TT + GT are more likely to develop the AMD, whereas no significant difference was observed for rs13278062 under other models. No association was detected with the other six SNPs and AMD under various genetic models. CONCLUSION This case-control association study has indicated that TNFRSF10A rs13278062 is associated with AMD under the heterozygous and dominant models, suggesting that the TNFRSF10A variant may be involved in the development of AMD among ethnic Han Chinese population.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Objective:To explore the status of early social function in young and middle-aged patients after percutaneous coronary intervention (PCI) and analyze its influencing factors, so as to provide a basis for formulating relevant intervention measures.Methods:From July to December 2021, the convenient sampling method was used to select 110 young and middle-aged patients with coronary heart disease after PCI in the First Affiliated Hospital of Harbin Medical University as the research objects. The general information questionnaire, Social Disability Screening Schedule (SDSS) , Social Support Rate Scale (SSRS) and General Self-Efficacy Scale (GSES) were used to investigate the patients. Univariate analysis and multiple linear regression analysis were used to explore the influencing factors of early social function in young and middle-aged patients with coronary heart disease after PCI. A total of 110 questionnaires were distributed and 106 valid questionnaires were recovered, with an effective recovery rate of 96.36% (106/110) .Results:The scores of SDSS, SSRS and GSES of 106 young and middle-aged patients after PCI were (3.89±1.63) , (38.80±7.02) and (21.08±6.39) , respectively. The results of univariate analysis showed that there were statistically significant differences in SDSS scores among patients with different gender, family per capita monthly income, education level and number of stents ( P<0.01) . The results of multiple linear regression analysis showed that gender, family per capita monthly income, education level, number of stents, general self-efficacy and social support were the influencing factors of early social function in young and middle-aged patients with coronary heart disease after PCI ( P<0.05) . Conclusions:The status of early social function in young and middle-aged patients with coronary heart disease after PCI is not ideal. Medical staff should give more intervention and guidance to patients after PCI who are female, have a lower education level, have a lower per capita monthly family income and have a large number of stents, consider the influence of self-efficacy and social support on the social function of patients and formulate corresponding intervention measures according to the influencing factors, so as to improve the level of social function of patients.

Objective:To investigate the potential pleiotropism of cancer-related single nucleotide polymorphisms (SNPs) among Chinese population.Methods:Based on the catalogue of GWAS jointly constructed by the National Human Genome Research Institute and the European Institute of Bioinformatics, according to population origin (Chinese population and non-Chinese population) and disease traits (cancer and non-cancer traits). All SNPs found by GWAS before August 2020 were divided into four categories: cancer in Chinese population, non-cancer in Chinese population, cancer in non-Chinese population and non-cancer in non-Chinese population. The number, correlation and linkage of the four categories of SNPs were described.Results:By August 2020, a total of 196 813 SNPs from 4 096 GWAS were included in the GWAS directory. The information that SNPs refer to unknown or were not related to the disease was excluded, and 117 441 independent SNPs were finally included. There were 619 SNPs related to cancer and 9 569 SNPs related to non-cancer disease in Chinese population, respectively. There were 4 624 SNPs related to cancer and 106 448 SNPs related to non-cancer disease (trait) in non-Chinese population, respectively. Three SNPs, rs2736100, rs6983267 and rs401681, were associated with two or more types of cancer in both Chinese and non-Chinese populations. Seven SNPs, rs7705526, rs2736100, rs10993994, rs2735839, rs4430796, rs174537 and rs9271588, were associated with cancer and non-cancer diseases in both Chinese and non-Chinese populations, respectively.Conclusion:There is a potential pleiotropism of cancer-related SNPs in Chinese population.

Coronavirus disease 2019(COVID-19),which is caused by SARS-CoV-2,varies with regard to symptoms and mortality rates among populations.Humoral immunity plays critical roles in SARS-CoV-2 infection and recovery from COVID-19.However,differences in immune responses and clinical features among COVID-19 patients remain largely unknown.Here,we report a database for COVID-19-specific IgG/IgM immune responses and clinical parameters(named COVID-ONE-hi).COVID-ONE-hi is based on the data that contain the IgG/IgM responses to 24 full-length/truncated proteins corresponding to 20 of 28 known SARS-CoV-2 proteins and 199 spike protein peptides against 2360 serum samples collected from 783 COVID-19 patients.In addition,96 clinical parameters for the 2360 serum samples and basic information for the 783 patients are integrated into the database.Furthermore,COVID-ONE-hi provides a dashboard for defining samples and a one-click analysis pipeline for a single group or paired groups.A set of samples of interest is easily defined by adjusting the scale bars of a variety of parameters.After the"START"button is clicked,one can readily obtain a comprehensive analysis report for further interpretation.COVID-ONE-hi is freely available at www.COVID-ONE.cn.
