METHODS: The study consisted of 820 medical staff from different departments of 5 hospitals, including doctor, nurse, technician, and administrator. Awareness level was evaluated with an interviewer-study. RESULTS AND CONCLUSION: Totally 805 interviewer-studies were effect. The correct answer fill rate in department of ophthalmology was higher than other departments. Different measures should be taken to teach the medical staff to improve the awareness level of the transplantation and corneal donation.

Objective: To study the efficacy of relieving the postoperation pain by using mesh to stuture and fixate tissue during transabdominal preperitoneal hernioplasty (TAPP) in inguinal hernia patients. Metholds: A retrospective analysis of 156 patients with inguinal hernia who underwent TAPP in Nanhai Hospital Affiliated to Southern Medical University from January 2016 to January 2017 was conducted, they were males, the average age was 50.84 years and the age range was from 33 to 62 years. Patients were divided into sacral nail group (n=120) and absorbable line group (n=36) according to the different methods of fixation of the iliac crest. Among them, the patients in the sacral nail group were fixed with iliac screws, and the patients in the absorbable line group were sutured with absorbable sutures. Pain visual analog scale (VAS) was used to compare the extent of postoperative pain in both groups. After the operation, through the outpatient review and telephone follow-up for 1 year, observed the recurrence of inguinal hernia in both groups. Measurement data were expressed as mean ± standard deviation (Mean±SD), t-test was used for comparison between groups; the Chi-square test was used to compare the count data between the two groups. Results: Among them, 19 patients with moderate pain after operation in the nail group had an incidence of 15.8%. Two patients with moderate pain in the absorbable line group had an incidence of 5.6%. The difference between the two groups was statistically significant (χ²=2.511, P=0.013). The pain VAS of the patients in the sacral nail group was (3.08±1.36), and the absorbable line group was (2.50±0.91), the difference between the two groups was statistically significant (t=2.973, P=0.001). All patients had no recurrence after outpatient review and telephone follow-up for 1 year. Conclusion In TAPP, the application of absorbable suture fixed patch can effectively reduce postoperative pain.

Objective:On the basis of summarizing the previous studies on the access and pricing strategies of multi-indication drugs,based on the actual situation in China,it develops the access and pricing strategies of multi-indication drugs applicable to the adjustment mechanism of China's health insurance catalog and carry out feasibility analysis,with a view to providing methodological support for the national health insurance department in the adjustment of the health insurance catalog in the future.Methods:First,through literature review and expert survey,it sorts out the medical insurance access and pricing strategies for multi-indication drugs that may be applicable in China.Secondly,a feasibility evaluation framework for National Drug Insurance List(NRDL)access and pricing strategies for multi-indication drugs is constructed through literature review,and various stakeholders in the NRDL process are invited to conduct feasibility scores based on the questionnaire.In addition,9 pathways are identified through expert research,and various stakeholders in NRDL process are invited to conduct path analysis based on questionnaires.Finally,relevant recommendations are formed based on the research results.Results:According to the results of the feasibility evaluation the direct access is less feasi-ble,while negotiated access and simplified negotiated access are comparable;pricing by weighted average was less feasible,pricing by primary indication and pricing by minimum value are comparable.The results of the pathway analysis show that differences in health insurance access and pricing strategies for selecting drugs with multiple indications under different pathways.Conclusion:It is needed to refine the medical insurance access and price calculation methods for drugs with multiple indications;improve the database construction to support refined calculation of medical insurance;and actively explore the innovative payment methods for medical insurance with multiple indications.

Objective To investigate the effect of parent-child alienation on depression in surface ship officers and soldiers based on the theory of"diathesis-stress",and the mediating role of resilience between parent-child alienation and depression in them.Methods A cross-sectional study was conducted on 599 officers and soldiers from a surface ship unit.The participants were surveyed with inventory of alienation toward parents,connor-davidson resilience scale and patient health questionnaire-9 to obtain and analyze their demographic-military characteristics of their depression scores.The participants with depression scores ≥5 were recruited as the subjects,and Spearman correlation analysis was used to explore the correlation among parent-child alienation,resilience and depression.On the basis of hierarchical regression analysis,AMOS software was used to establish a structural equation modelling of intermediary effects.Results The depression score was 1(0,4)in the participants,and the depression scores of those with service length ≥11 years were comparatively higher than those with shorter length.Our results indicated that parent-child alienation was positive correlated with depression(r=0.451,P＜0.001),while resilience was negatively correlated with depression and parent-child alienation(r=-0.412,-0.407,P＜0.001).Regression analysis revealed that parent-child alienation had a direct positive predictive value for depression(β=0.574,P＜0.001),and resilience showed a negative predictive value for depression(β=-0.211,P＜0.01).Model analysis displayed that resilience had a significant mediating role in the effect of parent-child alienation on depression among these surface ship officers and soldiers,with an effect value of 0.088,and accounting for 15.86％of the total effect.Conclusion Parent-child alienation has a significant influence on depression among surface ship officers and soldiers,with resilience playing a partial mediating role.

To investigate the association between red blood cell volume distribution width (RDW) and osteophytes.
 Methods: This cross-sectional study was conducted in the Department of Health Examination Center of Xiangya Hospital, Central South University in Changsha, Hunan Province, China. A total of 8 334 subjects were included in this study. The severity of osteophytes was graded using the criteria of the Osteoarthritis Research Society International (OARSI). Osteophytes incident was defined as at least one side of the knee had a osteophytes grade ≥1. According to the quartiles of the RDW level, the subjects were divided into 4 groups. Multivariate logistic regression analysis was used to calculate the odds ratio (OR) and the 95% confidence interval (CI) of the knee osteophytes incidence between each RDW group and the lowest level group. Tests for linear trends were conducted based on logistic regression using a median variable of RDW level in each category.
 Results: Quartile 1 (Q1), RDW≤9.78; Q2, 9.7813.10. The multivariable adjusted ORs (95%CI) of the prevalence of osteophytes were 1.38 (1.06 to 1.79) in the second percentile interval, and 1.27 (0.97 to 1.66) and 1.50 (1.15 to 1.94) in the third and fourth percentile interval, respectively. Test for linear trends suggested that there was a positive association between the RDW level and the risk of knee osteophytes incidence (P=0.019).
 Conclusion: The risk of osteophytes incidence increases with the increasing RDW levels.

AIM:To explore the roles and associations of hepatocyte nuclear factor 4 alpha(HNF4A)and mu-protocadherin(MUCDHL)in the kidney of diabetic mice.METHODS:(1)A cohort of six 12-week-old db/m mice and six db/db mice were selected and maintained on a standard diet until 16 weeks.The protein levels of fibronectin(FN),collagen type III(Col-III),E-cadherin,α-smooth muscle actin(α-SMA),HNF4A,Snail and MUCDHL in renal tissues were scrutinized using Western blot.Immunohistochemical staining was conducted to observe the distribution and expres-sion of FN,HNF4A and MUCDHL.(2)Mouse renal tubular epithelial cells(mRTEC)were cultured in vitro and catego-rized into groups:normal glucose(NG)group,high glucose(HG)group,overexpression control groups(NG+vector and HG+vector),overexpression groups(NG+OE-MUCDHL,HG+OE-MUCDHL,NG+OE-HNF4A and HG+OE-HNF4A),knockdown control groups(NG+control and HG+control),and knockdown groups(NG+si-MUCDHL,HG+si-MUCDHL,NG+si-HNF4A and HG+si-HNF4A).The relevant protein levels were also detected by Western blot.RESULTS:(1)In db/db group,elevated body weight,blood glucose and urine albumin-to-creatinine ratio(UACR)indicated significant re-nal injury.Compared with db/m group,the mice in db/db group exhibited increased expression of FN,Col-III,α-SMA and Snail,and decreased expression of E-cadherin,HNF4A and MUCDHL.MUCDHL was predominantly expressed in the apical membrane of renal tubular epithelial cells,FN in the tubular mesenchyme,and HNF4A in the plasma and nu-cleus of renal tubular cells.(2)In HG group,there was an up-regulation in the expression of fibrosis-related proteins and a down-regulation in the expression of E-cadherin,HNF4A and MUCDHL compared with NG group.Overexpression of MUCDHL led to a decrease in the expression of FN,Col-III,α-SMA and Snail proteins,an increase in the expression of E-cadherin and MUCDHL proteins,and unaltered expression of HNF4A.Knockdown of MUCDHL resulted in a reversal of the aforementioned effects,with HNF4A expression remaining unaltered.Overexpression of HNF4A led to an increased ex-pression of MUCDHL,and the expression changes of the remaining indicators were consistent with the overexpression of MUCDHL.Knockdown of HNF4A reversed the aforementioned effects.MUCDHL may represent a downstream target gene of HNF4A.CONCLUSION:The diminished expression of HNF4A and MUCDHL in the renal tubules of diabetic mice implies their involvement in the progression of renal fibrosis in diabetic kidney disease(DKD).HNF4A may potentially impede the progression of renal fibrosis in DKD by up-regulating the expression of MUCDHL.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.
