Objective To investigate the endoscopic prevalence of erosive esophagitis (EE) among 13 hospitals in Guangdong province of China. Methods Retrospectively reviewed all the cases (63459 cases) that received oesophagogastrodeuodenoscopy in 13 main hospitals in Guangdong province of China in 2003. Los Angeles criteria for classification of erosive esophagitis were employed as the basis of analysis. Results One thousand two hundreds and sixty-three patients (age range 3-90yr, mean 50. 2 ?17. 1 ) were found to have EE. The overall prevalence of EE was 1. 99% (1263/63459). The prevalence of EE in A, B, C, and D grade were 0. 94% , 0. 69% , 0. 21% and 0. 14% respectively. Age correlated positively on endoscopic grading of EE (F=22. 932, P

Objective:To analyze and compare the clinical indicators and the liver failure-related prognostic score of patients with amanita phalloides poisoning with different prognoses, and to explore potential prognostic indicators.Methods:A retrospective case-control study was conducted. The clinical data of 52 patients with amanita phalloides poisoning admitted to the department of emergency of Xijing Hospital Affiliated to Air Force Medical University from September 2016 to September 2021 were collected, including general information (gender, age), clinical indicators at admission [mean arterial pressure (MAP), total bilirubin (TBil), aspartate transaminase (AST), alanine transaminase (ALT), albumin (ALB), serum creatinine (SCr), blood urea nitrogen (BUN), creatine kinase (CK), D-dimer, fibrinogen degradation product (FDP), prothrombin time (PT), activated partial thromboplastin time (APTT), prothrombin activity (PTA), international normalized ratio (INR), white blood cell count (WBC), platelet count (PLT)], liver failure-related prognostic score [sequential organ failure assessment (SOFA), chronic liver failure (CLIF)-SOFA score, European Foundation for the Study of Chronic Liver Failure-organ failure (CLIF-C OF)], and 28-day outcome. The clinical indicators and liver failure-related prognostic scores of the patients with different prognoses were compared. Receiver operator characteristic curve (ROC curve) was used to determine the prognostic value of statistically significant indicators between different prognosis of patients with amanita poisoning.Results:A total of 45 patients were enrolled, of which 38 survived and 7 died within 28 days. The coagulation indicators including PT, APTT, INR, and liver failure-related prognostic scores including SOFA score, CLIF-SOFA score, and CLIF-C OF score in the patients of death group were significantly higher than those in the survival group [PT (s): 69.59±15.94 vs. 25.99±4.64, APTT (s): 83.44±17.82 vs. 42.64±3.79, INR: 6.13±1.47 vs. 2.07±0.33, SOFA score: 11.57±1.38 vs. 6.03±0.77, CLIF-SOFA score: 9.86±2.17 vs. 5.55±0.67, CLIF-C OF score: 11.71±0.97 vs. 8.37±0.35], and PLT was significantly lowered (×10 9/L: 80.57±29.65 vs. 169.60±11.80, all P < 0.05). ROC curves showed that coagulation indicators including PT, APTT, INR, PLT, and liver failure-related prognostic scores including SOFA score and CLIF-C OF score were associated with the prognosis of patients with amanita phalloides poisoning, with the area under the ROC curve (AUC) of > 0.75. The sensitivity of the clinical indicators was above 85%, and the AUC and specificity of INR were the highest, which were 0.88 [95% confidence interval (95% CI) was 0.74-1.00] and 83.0%, respectively; meanwhile, the sensitivity of the liver failure-related prognostic scores was 100%, and the AUC and specificity of the CLIF-C OF score were the highest, which were 0.86 (95% CI was 0.74-0.99) and 66.0%, respectively. Conclusion:INR and CLIF-C OF score can be used to evaluate the poor prognosis of patients with amanita phalloides poisoning.

Objective:To explore whether the action research on the pre-service training evaluation system of "Internet + TCM Nursing" guided by CIPP (context, input, process and product) and Kirkpatrick Model can improve the training effect of nursing staff under the background of internet and TCM nursing service.Methods:Taking 211 nurses of "Internet + TCM Nursing" in Guangdong Provincial Hospital of TCM from 2019 to 2020 as the research objects, action teams were made, and the data were collected and analyzed by various methods. According to the collected data, the action teams constructed the training scheme of "Internet + TCM Nursing", the compilation requirements of "internet + TCM Nursing", the case optimization scheme of "internet + TCM Nursing" process, and the evaluation model of "internet + TCM Nursing". After the training, the nurses' knowledge, skills and related attitudes, the general reaction and feelings to the training programs, and the evaluation of nurses' work performance by the competent leaders, medical staff and clients were compared by comparing their scores and issuing self-made questionnaires. SPSS 20.0 software was used for statistical analysis.Results:The results showed that the theoretical scores of nurses after training were (85.16±6.22) points, and the case assessment scores after training [(81.22±7.03) points] were higher than the previous theoretical scores [(61.23±12.90) points] and the case assessment scores [(59.54±14.41) points], with statistical significance ( P<0.001). The results of self-made questionnaire showed that there were significant differences in theoretical knowledge, skills and related attitudes among nurses after training ( P<0.001). In the process of training, there were statistically significant differences in training content, teacher training, training implementation and training guarantee at the end of training ( P<0.001). After training, there were significant differences in the evaluation of nurses' job performance by leaders in charge, medical staff and clients improved in knowledge and skills, professional ethics, working process and learning ability, and the improvement rate ( P<0.001). Conclusion:Action research is an effective research method to continuously improve nursing training. The optimization scheme of "internet + TCM Nursing" nurses based on CIPP and Kirkpatrick Model through action research can effectively improve the training effect.

The Guangdong Province Laboratory Animals Ordinance (the GPLAO), officially enacted and implemented in October 2010, marked a new phase of legal management in the administration of laboratory animals in Guangdong Province. The GPLAO clearly authorizes the laboratory animal monitoring institutes in Guangdong Province to conduct laboratory animal quality monitoring and assume corresponding legal responsibilities. It also specifies the standards for the production and use of laboratory animals, while bringing attention to laboratory animal welfare and ethics. Through the formulation of supporting documents, the active promotion of the standardization and regulation of administrative law enforcement, and the implementation of measures to delegate power, streamline administration, and optimize government services, significant improvements have been made in the standardized management of laboratory animals in Guangdong Province and in supporting the innovative development of biomedicine. Moreover, notable achievements have been made in areas such as the construction of experimental animal technology platforms, standardization work, the preservation and development of unique resources, and talent pool development. However, with the advancements in science and technology, social economy, and legislative work, some aspects in the GPLAO have been identified for improvement. These include the need for clearer provisions on laboratory animal welfare, more specific guidelines for the management of genetically engineered animals, improved regulations on the safety and welfare of practitioners, further refined implementation of the "one-vote veto system", continued promotion of laboratory animal standardization, and the exploration of effective mechanisms for resource sharing. This paper reviews and summarizes the institutional characteristics, post-legislation implementation, and effectiveness of the GPLAO, as well as the issues and countermeasures identified during the implementation. It concludes the laboratory animals management practices in Guangdong Province during the past 10 years, aiming to provide a reference for laboratory animal legislation.
