The ethics committee of organ transplantation technology and clinical application in a hospital has encountered some difficulties and typical cases in its review work and practice for many years. Sometimes, it is difficult to make a decision in these dilemmas. Based on the previous experience of the hospital in the ethical review of organ donation and transplantation, combined with two typical cases, this paper discussed and analyzed two review points of whether the voluntary unpaid donation and the principle of informed consent were met, and whether the risk-benefit ratio was reasonable, and put forward relevant ethical and legal countermeasure for further research by institutional ethics committees and other parties, in order to provide reference for discussing the practical problems and ethical confusion of ethical review of organ donation and transplantation.

Currently,the ethical review model for organ donation and transplantation in domestic hospitals is generally characterized by suddenness,unpredictability,tight time,difficulty in convening meetings and training committee members,as well as generally low quality and efficiency of ethical review,which cannot meet clinical needs and cause the waste of some scarce resources.The team of the Clinical Application Center of Human Organ Transplantation and the Ethics Committee of the First People's Hospital of Kunming combine more than 10 years of review practice experience,as well as continuously explore and optimize the ethical review process and operating procedures for organ donation and transplantation.The special application has been approved and jointly developed with Soochow University and the Medical Ethics Committee of Fujian Province to build a full-process information software system management platform for organ ethical review of donation and transplantation,giving the full play the advantages of the review information system in improving work efficiency and review quality,facilitating full-process information management,and conducting online training and learning for committee members,with a view to providing a specialized practical model for addressing the difficulties and challenges related to ethical review of human organ donation and transplantation.

Objective:To investigate the influencing factors of surgical site infection (SSI) after abdominal surgery.Methods:The retrospective cross-sectional study was conducted. The clinical data of 567 patients undergoing abdominal surgery in 6 medical centers, including 445 cases in the Zhengzhou Central Hospital Affiliated to Zhengzhou University, 54 cases in the the First Affiliated Hospital of Zhengzhou University, 49 cases in the Shangqiu First People's Hospital, 10 cases in the Luoyang Central Hospital, 5 cases in the First Affiliated Hospital of Henan University of Science and Technology and 4 cases in the Henan Provincial People's Hospital, from June 1 to June 30, 2020 were collected. There were 284 males and 283 females, aged (51±18)years. Observation indicators: (1) incidence of SSI after surgery; (2) influencing factors of SSI. Follow-up was conducted using outpatient examination and telephone interview to detect the incidence of SSI. Patients without implant were followed up within postoperative 30 days, and patients with implant were followed up within postoperative 1 year. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measure-ment data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was performed using the chi-square test or Fisher exact probability. Univariate analysis was performed using the corresponding statistical methods. Multivariate analysis was performed using the Logistic stepwise regression model advance method. Results:(1) Incidence of SSI after surgery. All the 567 patients were followed up after surgery as planned. There were 27 cases with SSI after surgery including 9 cases with superficial incision infection, 9 cases with deep incision infection, 9 cases with organ/gap infection. Of the 27 cases with SSI after surgery, 18 cases with positive results of incisional microbial culture including 8 cases with positive results of Escherichia coli, 6 cases with positive results of Klebsiella pneumonia, 3 cases with positive results of Enterococcus faecium and 1 case with positive result of Pseudomonas aeruginosa. (2) Influencing factors of SSI. Results of univariate analysis showed that age, preoperative hemoglo-bin, preoperative albumin, preoperative fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site, surgical incision type, duration of intensive cure unite, duration of post-operative hospital stay, duration of total hospital stay, operation time, hospital expense were related factors affecting the incidence of SSI of patients undergoing abdominal surgery ( χ2=40.12, Z=?4.22, ?2.21, ?4.75, χ2=7.07, 16.43, 38.06, 17.50, Z=?4.43, ?4.42, ?7.14, ?7.15, ?5.90, P<0.05) and the American Association of Anesthesiologists Classification, preoperative oral antibiotics, surgical methods and postoperative intensive care unit stay were related factors affecting the incidence of SSI of patients undergoing abdominal surgery ( P<0.05). Results of multivariate analysis showed that age, preopera-tive fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site as appendix and rectum, surgical methods, surgical incision type as infective incision and polluted incision, operation time were independent factors affecting the incidence of SSI of patients undergoing abdo-minal surgery ( odds ratio=7.69, 1.21, 0.27, 5.82, 5.19, 19.08, 0.23, 27.76, 4.97, 1.01, 95% confidence intervals as 2.04?28.95, 1.04?1.41, 0.08?0.94, 1.36?24.85, 1.10?24.43, 4.48?81.25, 0.06?0.87, 2.54?303.53, 1.12?22.14, 1.01?1.02, P<0.05). Conclusion:Age, preoperative fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site as appendix and rectum, surgical methods, surgical incision type as infective incision and polluted incision, operation time are independent factors affecting the incidence of SSI of patients undergoing abdominal surgery.

Objective: To investigate the clinical value of the serum new molecular markers, soluble triggering receptor expressed on myeloid cells-1(sTREM-1)and soluble hemoglobin scavenger receptor(sCD163), in the diagnosis of sepsis in elderly patients with burns. Methods: A total of 58 inpatients with burns from Jun 2017 to June 2018 were enrolled in the study.Patients were divided into three groups: the sepsis group(n=12), the localized infection group(n=21)and the non-infection group(n=29). The levels of sTREM-1 and sCD163 were determined by enzyme-linked immunosorbent assays(ELISAs). The clinical diagnostic value of sTREM-1 and sCD163 was assessed by receiver operating characteristic(ROC)curve analysis. Results: There was a statistically significant difference in the levels of sTREM-1 and sCD163 at day 1 between the three groups(F=20.994 and 38.363, P<0.01). Serum levels of sTREM-1 and sCD163 were higher in the sepsis group than in the localized infection group and the non-infection group.Serum levels of sTREM-1 and sCD163 were higher in the localized infection group than in the non-infection group.Serum levels of sTREM-1 and sCD163 were lower at day 7 than those at day 1 in all groups(F=21.242 and 41.035, P<0.01). Serum sTREM-1 levels were positively correlated with serum sCD163 levels(r=0.609, P=0.000). The AUC of sTREM-1 and sCD163 for the diagnosis of sepsis was 0.880(95%CI: 0.816~0.926). Conclusions Serum levels of sTREM-1 and sCD163 are elevated with increasing degrees of infection.Monitoring serum sTREM-1 and sCD163 levels is helpful for the diagnosis of sepsis in elderly patients with burns.

Objective? To understand the attitude toward hospice care and its infLuencing factors among undergraduate nursing students majoring in TraditionaL Chinese Medicine (TCM), and to provide basis for nursing educators to formuLate hospice care training strategies. Methods? Using convenient sampLing method, a totaL of 827 undergraduate nursing students from 3 TCM universities in Shandong, Shanxi and He'nan provinces were seLected as subjects from September to October 2018. The generaL information questionnaire and the Chinese version of FrommeLt Attitude Toward Care of the Dying (FATCOD) were used. MuLtipLe Linear regression was used to anaLyze infLuencing factors. ResuLts? The totaL score of FATCOD among the 827 undergraduate TCM nursing students was (101.32±9.15). Univariate Linear regression resuLts showed that gender, singLe-chiLd status, wiLLingness to choose nursing major, attitudes toward nursing, the situation where students discussed death with famiLy, experience with funeraLs, experience with terminaL reLatives, wiLLingness to take care terminaL patients were aLL factors that couLd affect the attitudes toward hospice care among nursing students (t/F=-3.066,-2.783, 3.289, 12.577, 10.638, 2.680, -2.251, 8.697;P＜0.05). MuLtipLe Linear regression anaLysis resuLts showed that gender, singLe-chiLd status, attitudes toward nursing, wiLLingness to take care terminaL patients, experience with funeraLs, the situation where students discussed death with famiLy, experience with terminaL reLatives have an impact on the attitude toward hospice care (P＜ 0.05). ConcLusions? The attitude toward hospice care among undergraduate TCM nursing students needs to be further improved. Educators shouLd adopt various methods of teaching to carry out death education according to the infLuencing factors, and to cuLtivate proper perception of death and improve the enthusiasm for hospice care.

Objective: To analyze the effectiveness and response status of China Infectious Disease Automated Alert and Response System (CIDARS) in Hunan province from 2012 to 2016 for improving the system. Methods: To collect the early warning signals, the number of suspected events, the result of on-site investigation, the signal response time and the result of public health emergencies, and the χ² test, correlation analysis and non-parametric test were used to analyze the information on CIDARS in Hunan Province during the period from 2012 to 2016. Results: A total of 108 188 signals were generated by the CIDARS in Hunan Province; The warning involved 30 kinds of infectious diseases and 138 counties (districts), and each county (district) received 3.00 weekly warning messages on average; 100% early warning signal was responded, 2 h response rate was 92.43%; The median response time (P25-P75) was 0.28 (0.11-0.77) h in the single case warning, and the five-year timely response rate showed an upward trend year by year (trend χ²=58.89, P<0.05); the median response time (P25-P75) was 0.56 (0.28~1.06) h in the time series warning, and the five-year timely response rate showed no trend (trend χ²=2.43, P>0.05); the time series warning response was more timely than the single case warning, and the difference between the two timely response rates was statistically significant(χ²=5156.60, P<0.05). The studies showed that the sensitivity, specificity, and detection timeliness of the system were 84.80%, 69.53%, and 2.80 d, respectively; There was no significant difference in the infectious diseases detecting timeliness of CIDARS(H=8.75, P>0.05); the system had the best effect in rubella, and the positive likelihood ratio of rubella is 4.36. Conclusions CIDARS in Hunan province runs well overall with high sensitivity and timely response to the early warning signals, but the specificity of the early warning system needs to be improved. The quality of the epidemic report of infectious diseases needs to be further improved, and the early warning parameters and warning method should be adjusted according to the characteristics of different diseases and the differences among different regions.
