epsis is a systemic inflammatory response syndrome triggered by infection， and its high mortality rate is closely associated with immune imbalance， particularly the imbalance in the differentiation of helper T cell （Th） cell subsets [Th1， Th2， Th17， regulatory T cell （Treg） ] . In recent years， traditional Chinese medicine （TCM）， with its characteristics of multi-component and multi-target actions， has demonstrated unique advantages in regulating Th cell differentiation and function， as well as correcting immune imbalances in sepsis， offering new perspectives for immunotherapy of sepsis. This review summarizes relevant studies on the regulation of Th cell differentiation for sepsis treatment by TCM monomers and active ingredients （such as Astragalus membranaceus ， Scutellaria baicalensis ， Coptis chinensis ， Rheum palmatum ， Ganoderma lucidum ， Ginkgo biloba ， and Cistanche deserticola ）， the alcohol extract of Dai Baijie， and TCM formulas and preparations categorized as blood-activating and stasis-removing， purgative and laxative， warming and tonifying yang， and tonifying qi and nourishing yin. The results indicate that these TCM monomers， active ingredients， extracts， formulas， and preparations can regulate the Th1/Th2 and Th17/Treg balance， target the differentiation balance of Th cell subsets， alleviate inflammatory responses， or improve immune suppression， thereby exerting therapeutic effects on sepsis.

Sensorineural hearing loss (SNHL), the most commonly-occurring form of hearing loss, is caused mainly by injury to or the loss of hair cells and spiral ganglion neurons in the cochlea. Numerous environmental and physiological factors have been shown to cause acquired SNHL, such as ototoxic drugs, noise exposure, aging, infections, and diseases. Several programmed cell death (PCD) pathways have been reported to be involved in SNHL, especially some novel PCD pathways that have only recently been reported, such as ferroptosis, necroptosis, and pyroptosis. Here we summarize these PCD pathways and their roles and mechanisms in SNHL, aiming to provide new insights and potential therapeutic strategies for SNHL by targeting these PCD pathways.

Methods:The logistic regression algorithm was used to construct the risk grade of adverse event of medical equipment of the department of cardiovascular medicine,and data collation and analysis were used to realize monitoring and management control for medical equipment. The 31 sets used medical equipment in the Department of Cardiovascular equipment of Xi'an No.3 Hospital from October 2021 to October 2022 were selected. Equipment management was conducted using conventional methods for risk management from October 2021 to October 2022,while equipment management from November 2022 to November 2023 adopted a risk classification model based on logistic regression was used to conduct risk management. A total of 204 logs of equipment application of the two kinds of management methods were selected,and each method selected 102 logs. The error rate of clinical operation,the occurrence of equipment failure,the timeliness score of risk management of equipment and the rate of hidden danger of safety risk of equipment were compared between the two kinds of management methods. Results:The number of error use of equipment,operational error and man-made mistake were respectively 3,2 and 2 in 102 logs that were managed by using risk classification model,and the incidence rates of them were respectively 2.94％,1.97％ and 1.97％,which were lower than those by using conventional management method,and the differences were statistically significant (x2=11.613,13.058,14.191,P<0.05). The average failure rate,self-maintenance rate of failure and average scrap rate of the medical equipment of the department of cardiovascular medicine of the management with risk classification model were respectively (0.56±0.22)％,(0.79±0.19)％ and (0.90±0.22)％,all of which were lower than those of conventional management method,and the differences were statistically significant (x2=16.971,15.531,15.809,P<0.05). The risk early warning,risk identification,and the average timeliness scores of risk prevention and control of using the management with risk classification model were respectively (90.29±8.69),(89.69±7.69),and (94.58±6.69),all of which were higher than those of using the management with conventional management method,and the differences were statistically significant (t=13.325,11.003,11.676,P<0.05). The number of mechanical injury,associated infection,and abnormal operation of equipment were respectively 1,1 and 2 in 31 medical equipment that were managed by risk classification model,and the incidence rates of them were respectively 3.23％,3.23％ and 6.45％,all of which were lower than those of conventional management methods,and the differences were statistical significances (x2=5.167,7.631,5.413,P<0.05),respectively. Conclusion:The application of a risk classification model based on logistic regression for medical equipment of the department of cardiovascular medicine can improve the utilization rate of equipment,and reduce the potential risk hidden danger of safety,and enhance the operation quality of equipment.

The intestinal flora and its metabolites are closely bound up with the metabolism and immune function of human body and at the meantime affect the metabolisms of nutrients and drugs,which play an important role in maintaining the physiological function.As the largest reservoir of microorganisms within the human body,the intestinal flora play a vital role in maintaining the health.Numerous studies have shown that the alteration of intestinal flora may not only affect the emergence of gastrointestinal diseases but also has impact on the common diseases of multiple systems,it may mediate the emergence and development of relevant diseases through gut-kid-ney axis,gut-liver axis,and gut-brain axis,and interact with the diseases.As a traditional Chinese medicine ex-ternal therapy,the traditional Chinese medicine enema therapy has remarkable advantages in treatment of various clinical diseases and shows significant effect on improvement of intestinal flora imbalance during the disease pro-gression.The effect of the traditional Chinese medicine enema therapy on improving the intestinal flora imbalance of the patients during the process of emergence and development of the common diseases is reviewed in the article.

Objective: To evaluate the efficacy and safety of adding toripalimab to bevacizumab and platinum-based chemotherapy as first-line treatment for refractory recurrent or metastatic (R/M) cervical cancer (CC). Methods: Patients were administered toripalimab (240 mg) + bevacizumab (7.5 mg/kg) combined with platinum-based chemotherapy once every three weeks for six cycles, followed by the maintenance therapy involving toripalimab + bevacizumab once every 3 weeks for 12 months or when disease progression or intolerable toxicity occurred. The primary endpoint was the objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors version 1.1. The secondary endpoints were safety profiles, disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). Results: Twenty-four patients were enrolled in this study and in the final analysis. The median follow-up duration was 18.6 (range, 3.3–28.5) months. The ORR was 83.3% (95% confidence interval [CI]=62.6–95.3) and the DCR was 95.8% (95% CI=78.9–99.9); 9 (37.5%) patients achieved complete response, 11 (45.8%) achieved partial response, and 3 (12.5%) had stable disease. The median PFS was 22.6 (95% CI=10.4–34.7) months and the median OS was not reached. The most common grade 3 treatment-related adverse events (AEs) were neutropenia (41.7%) and leukopenia (16.7%). The most common immune-related AEs (irAEs) were thyroid dysfunction (37.5%) and increased adrenocorticotropic hormone (37.5%) and serum cortisol levels (33.3%). No grade ≥3 irAEs were observed. Conclusion Toripalimab combined with bevacizumab and platinum-based chemotherapy show promising clinical efficacy and favorable safety profile, providing an alternative firstline treatment option for patients with R/M CC.

Objective: To understand the nutritional literacy level and associated factors of primary and secondary school students in Beijing, so as to provide a scientific basis for improving student nutrition. Methods: From October 2022 to May 2023, a multi stage cluster random sampling method was employed to select a total of 14 568 primary, junior and senior high school students from 16 districts (ecluding the Economic Technological Development area) in Beijing. Through a survey questionnaire on nutritional literacy and dietary hehavior of school age children, basic information as well as data on nutritional literacy levels across four dimensions:nutrition related knowledge concepts, food selection, food preparation, and food intake dimensions were obtained. The Wilcoxon rank sum test, Kruskal-Wallis test, Spearman correlation analysis, Chi square test and binary Logistic regression were used for the analysis. Results: The median total score of nutritional literacy among primary and secondary school students in Beijing was 68.8. Approximately 26.0% of primary and secondary school students achieved nutritional literacy standards. The median scores and rates of meeting the standards for nutrition related knowledge concepts, food selection, food preparation and food intake dimensions were 23.0, 42.1%; 17.0, 27.4%; 6.5, 33.5%; 23.0, 33.3%, respectively. There were positive correlations between all pairs of the four dimensions ( r=0.33-0.49, P <0.05). The results of multiple Logistic regression analysis showed that primary school students, junior high school students, female students, suburban students, caregivers with a college education level and a bachelor s degree or above were the positive arrelation factors that promoted the achievement of nutritional literacy standards ( OR =2.21, 1.39, 1.18, 1.27, 1.42, 1.66, P <0.05). Conclusion The literacy level of primary and secondary school students in Beijing needs to be significantly improved. School stage, gender, region and caregiver s education level are associated factors.

Objective To observe the application effects of scenario simulation combined with guided feedback teaching method in the teaching of endocrinology nursing interns.Methods A total of 180 nursing students who interned in the endocri-nology department of Southern Medical University Shenzhen Hospital from January 2020 to January 2023 were selected as the re-search subjects.Using a digital randomization method,the students were divided into a control group(90 cases)and an observa-tion group(90 cases).The control group received conventional teaching,while the observation group received scenario-based teaching combined with guided feedback teaching method.The intern performance,satisfaction of teaching instructors toward students,and students'satisfaction with teaching instructors were compared between the two groups.Results The intern per-formance of the observation group was higher and showed a greater improvement after training,with statistically significant differ-ences(P＜0.05).Both the students'satisfaction with teaching instructors and the teaching instructors'satisfaction with students in the observation group were higher than those in the control group,with statistically significant differences(P＜0.05).Conclusion The application of scenario simulation combined with guided feedback teaching method in the teaching of endocri-nology nursing interns can significantly improve students'intern performance,providing a more scientific basis for nursing intern-ship teaching.

Objective:To analyze the distribution of different SF3B1 genotypes in patients with myelodysplastic syndromes (MDS) and its prognostic value.Methods:Totally, 377MDS patients who were initially diagnosed in the First Affiliated Hospital of Nanjing Medical University from January 2014 to January 2022 were included in the retrospective analysis.The patients were divided into three different groups according to mutation stcote of SF3B1, including 317 patients with SF3B1 wild type (SF3B1 WT) (214 males and 103 females, 63(49, 71) years old),39 patients with SF3B1 K700E mutation(SF3B1 K700E(17 males and 22 females, 65(52, 73)years old)) and 21 patients with SF3B1 non-K700E mutation(SF3B1 non-K700E)(13 males and 8 females, 67(63, 73) years old). MDS-related 20 gene mutations were detected using targeted sequencing technology; Survival curves were constructed by the Kaplan-Meier method; Cox proportional hazards model was established to evaluate different factors at diagnosis on survival by univariate and multivariate analyses.. Results:Compared with SF3B1 non-K700E patients, SF3B1 K700E patients had a higher median absolute neutrophil count ( P=0.002) and were likely to be in the low/int-1 International Prognostic Scoring System (IPSS) categories ( P=0.023). A 20-gene targeted sequencing analysis showed that, compared with SF3B1 WT patients, SF3B1 K700E patients were associated with lower frequency of ASXL1 and U2AF1 mutations ( P=0.018 and P=0.003); while compared with SF3B1 non-K700E patients, the frequency of ASXL1 mutation was significantly lower in SF3B1 K700E cases ( P=0.029). Patients with SF3B1 K700E had better overall survival (OS) in comparison with SF3B1 WT and SF3B1 non-K700E in MDS patients ( P<0.001 and P=0.045, respectively). In comparison with SF3B1 WT patients, SF3B1 MUT patients had more favorable OS and progression-free survival (PFS) in MDS without excess blasts ( P<0.001 and P<0.001, respectively), but no significant difference was found in MDS with excess blasts ( P>0.05). Compared with SF3B1 WT patients, SF3B1 K700E patients had superior OS and PFS in the int-1 IPSS category ( P=0.010 and P=0.013, respectively). By multivariable analysis, the presence of SF3B1 K700Ewas an independent predictor of superior OS ( HR=0.461,95% CI 0.262-0.811, P=0.007). Conclusion:SF3B1 K700E and SF3B1 non-K700E patients had significantly improved OS in comparison with SF3B1 WT MDS patients. Furthermore, SF3B1 K700E patients were associated with a better OS compared with SF3B1 non-K700E MDS patients. SF3B1 mutation could not overcome the poor prognostic effect of excess blasts, which highlights the importance of the SF3B1 mutation subtype in risk assessment of MDS without excess blasts.
