Objective To assess the association of three polymorphisms in Megsin (rs1055901,rs1055902 and rs2689399) and susceptibility of IgA nephropathy in Asian population.Methods We conducted a comprehensive search of electronic CNKI,VIP,WangFang Data,CBM,Pubmed,Web of Science and Google Scholar database on the association between Megsin rs1055901,rs1055902 and rs2689399 polymorphism and susceptibility of IgA nephrology in Asian population (last search update on 2 May 2016).Stata 12.0 software was used to calculate the odds ratio (OR) and 95 ％ CI (confidence interval),as well as sensitivity and publication bias analyses.Results Six publications encompassing mine case-control studies were finally included,including 2 179 cases and 1 769 controls.Finally,no significant association between Megsin rs1055901 and rs1055902 polymorphism and IgA nephrology in Asian population was identified,while a significantly decreased risk of IgA nephrology for rs2689399 polymorphism,was identified in Asian population (G and C:OR=0.754,95％CI 0.592-0.961,P=0.022;GG and CC:OR=0.506,95％CI 0.287-0.892,P=0.019;GG and GC+CC:OR=0.551,95％CI 0.316-0.961,P=0.036).Conclusion Rs2689399 G allele and GG genotype of Megsin may be the protective factors for IgA nephropathy in Asian population.

The medical-industrial fusion training model combines the knowledge and technology of medical and engineering disciplines in the training of oncology graduate students, which can help accurate diagnosis and treatment of tumors, promote cooperation and innovation in oncology research, as well as promote the cultivation and exchanges of composite and innovative medical talents in oncology, promote the innovation and development of oncology diagnostic and treatment technology, and improve the survival rate and quality of life of oncology patients. This paper discusses the application of medical-industrial fusion training model in the training of o ncology professionals, and explores the new teaching mode of medical-industrial fusion thinking in the cultivation of complex and innovative medical talents in oncology under the background of "new medical science".

With the deepening of China's medical reform, people's demand for health is growing, which promotes the construction of "new medicine" and puts forward higher requirements for the cultivation and education of medical students. Undergraduate medical education is a crucial period for the growth of medical students, and how to do a good job in undergraduate teaching under the background of "new medicine" is currently a research hotspot. The clinical teaching stage is an important period for medical students to fully understand clinical disciplines and cultivate their understanding of specialties. Therefore, we should explore new teaching methods and means to adapt to the needs of the new era. In the context of "new medicine", the medical-engineering fusion diagnosis and treatment technology has become an important trend in the clinical diagnosis and treatment of oncology. In order to adapt to this change, clinical teaching and teaching management in oncology also need new exploration and research. Taking the clinical teaching of oncology as an example, this article discusses how to cultivate medical students' thinking of medical-engineering fusion.

Objective:To investigate the physical and mental experience, treatment compliance and use barriers of patients with insomnia in using digital cognitive behavioral therapy for insomnia (dCBT-I) in order to provide qualitative evidence for the development and application optimization of the dCBT-I technology paradigm.Methods:From July to November 2021, a semi-structured interview outline was used to conduct in-depth interviews with the dCBT-I users ( n=10) to record their original feelings about the use of dCBT-I. Interpretative phenomenology's text analysis was used to explore the participants' experience and cognition of dCBT-I. Results:Text analysis and key information calibration were carried out on the verbatim transcripts of semi-structured interview recordings, and three core themes were extracted, namely stickiness factor, use barrier and optimization direction, as well as eight sub-themes, namely professionalism, accessibility, benefit experience, difficulty in task execution, instruction generalization, difficulty in software operation, enrich treatment content and personalized guidance.Conclusion:The present study showed that participants were receptive to the dCBT-I intervention and would be benefited from it.However, dCBT-I still needs to be optimized and improved to reduce the operating difficulty and explore more appropriate timing of manual intervention.

Objective: To investigate the prognosis and influencing factors of postoperative low anterior resection syndrome (LARS) for rectal cancer patients undergoing laparoscopic sphincter-preserving radical resection. Methods: A retrospective case-control study was used in this study. Clinical data of 268 rectal cancer patients undergoing laparoscopic sphincter-preserving radical resection at Department of Gastrointestinal Surgery of The First Affiliated Hospital of Bengbu Medical College from January 2016 to January 2018 were retrospectively collected. Inclusion criteria: (1) operation procedure was total mesorectal excision (TME) and sphincter-preserving radical resection; (2) rectal cancer was confirmed by postoperative pathology; (3) age of patient was ≥ 18 years old. Exclusion criteria: (1) patient who had history of pelvic surgery and pelvic fractures, which would affect the anorectal function; (2) patient who had history of preoperative chronic constipation and irritable bowel syndrome, which would affect defecation; (3) patient who developed postoperative complications, such as anastomotic leakage, which would affect defecation function; (4) patient who received long-term use of drugs, which would affect the function of gastrointestinal tract or anus; (5) patient suffered from mental illness, who was unable to communicate properly; (6) patient who was lack of clinical data or had incomplete clinical data. Patients were followed up at 3, 6 and 12 months postoperatively, and LARS was diagnosed and graded according to the LARS score scale. The LARS score ranged from 0 to 42 points, and 0 to 20 was difined as no LARS, 21 to 29 was mild LARS, and 30 to 42 was severe LARS. LARS score >20 points at any time point was defined as postoperative LARS. Severe LARS transferring into mild LARS and mild LARS transferring into no LARS was defined as symptom improvement. Incidence and outcomes of LARS were evaluated. The factors associated with LARS outcomes were analyzed using χ² test and logistic regression model. Results: A total of 268 patients were enrolled. The incidence of LARS was 42.9% (115/268), 32.5% (87/268) and 20.1% (54/268) at 3, 6, and 12 months postoperatively respectively, and no new case of LARS was found after 3 months postoperatively. The incidence of mild LARS was 25.7% (69/268), 17.2% (46/268) and 8.6% (23/268) at 3, 6, and 12 months postoperatively respectively, and mild LARS incidence at 6 months was significantly lower than that at 3 months (χ²=5.857, P=0.016), and was significantly higher than that at 12 months (χ²=8.799, P=0.003). The incidence of severe LARS was 17.2% (46/268), 15.3% (41/268) and 11.6% (31/268) at 3, 6, and 12 months postoperatively respectively, without significant difference among 3 time points (all P>0.05). The improvement rate within one year after surgery in patients with mild LARS diagnosed at 3 months was significantly higher than that in patients with severe LARS (88.4% vs. 32.6%, χ²=38.340, P<0.001). Univariate analysis showed that female, distance from anastomosis to anal verge < 5 cm and tumor diameter ≥ 5 cm were associated with unsatisfied LARS outcomes (all P<0.05). Logistic regression analysis showed that distance from anastomosis to anal verge <5 cm was an independent risk factor for LARS outcome (OR=3.589, 95% CI: 1.163 to 2.198, P<0.001). Conclusions The incidence of LARS after laparoscopic sphincter-preserving radical resection decreases with time. The improvement rate within postoperative 1-year of severe LARS is lower than that of mild LARS. Low anastomotic position may lead to impaired improvement of LARS.
