Objective: To explore the mechanism of action of Zangjiangzhi capsule (ZJZC) in treating hyperlipidemia (HLP). Methods: The components of ZJZC were analyzed and identified using ultra-high performance liquid chromatography with Q-Exactive Orbitrap tandem mass spectrometry (UHPLC-Q-Exactive-Orbitrap-MS/MS). Network pharmacology analysis was used to explore the mechanism of action of ZJZC in HLP treatment. The SwissTargetPrediction database was used to predict compound targets, and GeneCards, DisGeNet, OMIM, and DRUGBANK databases were used to identify HLP-related targets. Protein–protein interaction diagrams were constructed using the STRING database. The targets were subjected to gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The “herb-ingredient-target” network was visualized using Cytoscape. Preliminary validation was performed using molecular docking and enzyme-linked immunosorbent assay. Results: Ninety compounds were identified in ZJZC, including 34 flavonoids, 12 phenols, 10 terpenoids, 10 alkaloids, 8 organic acids, 8 anthraquinones, and 9 other compounds. In total, 904 targets were identified for these compounds. Among them, 158 targets intersected with the HLP target network. Network pharmacology analysis showed that MAPK1, PPAR-α, RXRA, HSP90AA1, PIK3R1, AKT1, PIK3CA, IL6, TNF, and ESR1 are the key targets of action. KEGG enrichment analysis identified 164 pathways. Among these, the AGE-RAGE signaling pathway in diabetic complications, lipid and atherosclerosis pathways, regulation of lipids in adipocytes, and insulin resistance are related to HLP. Molecular docking showed good affinity between the key targets and ingredients. Further, ZJZC treatment in mice resulted in lower expression of MAPK1 protein and increased expression of PPAR-α protein, which have been shown to be strongly associated with HLP. Conclusions This study showed that ZJZC contains various active ingredients and can modulate multiple targets and pathways associated with HLP, providing evidence at the molecular level for its clinical application in the treatment of HLP.

【Objective】 To explore the model of "One Core, Multiple Elements" emergency blood donation volunteer team (referred to as the Model) . 【Methods】 The Nanjing City Voluntary Blood Donation Joint Meeting serves as the core, with diverse entities including party committees, government departments, district governments, social organizations, enterprises, blood donors, etc. Following the principles of "emergency response in emergencies, wartime readiness, combining regular and wartime efforts," and adhering to the framework of the Model, the emergency blood donation volunteer team system in Nanjing was constructed. 【Results】 1) After the construction of the Model (2018—2022), the total number of emergency blood donation volunteers in Nanjing City increased by 191% compared to the pre-construction period (2013—2017), with an average annual blood donation of 20 929, showing significant differences (P<0.05). 2) After the construction of the Model, the number of emergency blood donation during the winter and summer increased by 206% and 185%, respectively, compared to the pre-construction period, demonstrating significant differences (P< 0.05) .3) Prior to the construction of the Model, Nanjing lacked a relatively stable emergency volunteer team. After the construction, Nanjing established a total of 5 relatively stable volunteer teams, with the district-level government and township personnel accounting for the highest proportion (52.96%), followed by medical personnel (23.95%), enterprise team (11.10%), State-owned Assets Supervision and Administration Commission team (7%), and Nanjing municipal government team (4.98%). 4) Following the Model, during the COVID-19 pandemic, Nanjing successfully initiated two Level Ⅱ blood emergency responses, with emergency blood donations reaching 23 041. 【Conclusion】 The Model can effectively ensure the blood supply in Nanjing region during emergencies.

【Objective】 To analyze the implementation effect of points-based household registration policy for blood donors in Nanjing, so as to provide reference for other provinces and cities to develop incentive policies for blood donation. 【Methods】 The basic demographic profile, registration situation and deferral reasons of blood donors who applied for points-based household registration from 2017 to 2021 were analyzed by Excel. 【Results】 1) A total of 388 blood donors applied for points-based household registration for blood donation from 2017 to 2021, accounting for 0.042% of the total blood donors in Nanjing (388/923 160), and 357 applications were approved, accounting for 0.039% (357/923 160). 2) The proportion of male applicants was higher than that of female applicants (55.15% vs 44.85%). Applicants aged 26~35 accounted for the largest, followed by applicants aged 36~45, and applicants aged 18~25 accounted for the least. The proportion of applicants in Jiangsu province(23.27%) was higher than that of applicants from other provinces. The top three occupations were employees, workers and jobless. In terms of education level, applicants with junior high school education or below accounted for the largest, followed by high school and secondary school (35.05% vs 29.38% vs 23.20%). The proportion of first-time blood donors was the highest (33.24%). Among the repeated blood donors, blood donors who donated blood 2~3 times were with the highest share (23.93%). Nineteen donors(4.90%) got more than 100 points. 3) A total of 31 blood donors were deferred from 2017 to 2021, accounting for 7.90% of the total applicants. Among them, 23 applicants donated in other cities than Nanjing, 5 applicants failed to provide valid blood donation certificates, and 3 applicants submitted irrelevant material. 【Conclusion】 The implementation of points-based household registration policy for voluntary blood donors in Nanjing helped blood donors who could not reach other points due to low education level and income to become registered permanent residence in Nanjing

Although tumor treatment models have been continuously improved in clinical practice, cancer remains a serious threat to human health. The effect of probiotics on tumor therapy has received extensive attention. As a common colonizer of the intestinal mucosa, Akkermansia muciniphila(AKK) has a well-defined role in metabolic diseases, but its complex role in tumor development and therapeutic efficacy has not been fully elucidated. The unique properties and physiological roles of AKK play an important role in different solid tumors and it may be a potential biomarker. This article provides a review of previous studies and proposes clinical strategies to influence the abundance of AKK to provide a theoretical reference for the development of next-generation probiotics and the reshaping of the tumor treatment landscape.

Objective To construct a systematic evaluation model of the operation and management capacity of pub-lic hospitals,and to objectively and realistically assess the current status of the operation and management capacity of public hospitals.Methods The"input-process-output"framework was used to construct a systematic evaluation model for operation management capability.56 public hospitals at or above the secondary level were sampled to con-duct empirical research.Results The results showed that,operation management in current stage emphasized a"re-sult oriented"approach,with insufficient basic investment and unclear core activities.Increasing funding investment,strengthening hospital marketing,and improving output quality were the core tasks of operation management.The operation management were generally in the initial stage,and the overall ability was not strong.The ability advantages of tertiary hospitals were relatively prominent.Conclusion It recommended that public hospitals should focus on the five major elements of human resources,finance,information,systems and decision-making mechanisms to com-prehensively optimize operation management investment;precise core activities,and promote the modernization of the economic system by improving the efficiency of resource allocation;stimulate the potential of hospitals,medi-cal staff,and disciplines to improve the quality of comprehensive outputs.

Objective:To investigate the surgical efficacy and prognosis influencing factors of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment.Methods:The retrospective cohort study was conducted. The clinicopathological data of 91 patients with hilar cholangiocarcinoma who underwent surgery in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from April 2004 to April 2021 were collected. There were 59 males and 32 females, aged (61±10)years. Patients who were admitted from April 2004 to March 2014 underwent traditional surgical diagnosis and treatment, and patients who were admitted from April 2014 to April 2021 underwent multidisciplinary diagnosis and treatment. Observation indica-tors: (1) surgical situations; (2) postoperative situations; (3) postoperative pathological examina-tions; (4) postoperative prognosis analysis; (5) influencing factors of postoperative prognosis. Follow-up was conducted using telephone interview and outpatient examination. Patients were followed up once every 6 months after surgery to detect survival. The follow-up was up to April 2023. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curve and calculate survival rate. The Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard model. Results:(1) Surgical situations. Of the 91 patients, there were 65 cases receiving hemi- or expanded hemi-hepatectomy, 13 cases receiving tri-hepatectomy, 9 cases receiving partial hepatectomy, 4 cases receiving extrahepatic bile duct resection. There were 24 cases receiving combined vein resection and reconstruction, 8 cases receiving combined pancreaticoduodenectomy, 6 cases receiving com-bined hepatic artery resection and reconstruction, including 24 cases receiving extended radical surgery (tri-hepatectomy, hepatic artery resection and reconstruction, hepatopancreaticoduodenec-tomy). The operation time, volume of intraoperative blood loss and intraoperative blood transfusion rate of 91 patients was (590±124)minutes, 800(range, 500?1 200)mL and 75.8%(69/91), respectively. Of the 91 patients, cases receiving extended radical surgery, the volume of intraoperative blood loss were 4, 650(range, 300?1 000)mL in the 31 patients who were admitted from April 2004 to March 2014, versus 20, 875 (range, 500?1 375)mL in the 60 patients who were admitted from April 2014 to April 2021, showing significant differences between them ( χ2=4.39, Z=0.31, P<0.05). (2) Post-operative situations. The postoperative duration of hospital stay and cases with postoperative infectious complications were (27±17)days and 50 in the 91 patients. Cases with abdominal infection, cases with infection of incision, cases with bacteremia and cases with pulmonary infection were 43, 7, 5, 8 in the 91 patients. One patient might have multiple infectious complications. Cases with bile leakage, cases with delayed gastric emptying, cases with chylous leakage, cases with liver failure, cases with pancreatic fistula, cases with intraperitoneal hemorrhage, cases with reoperation, cases dead during the postoperative 90 days were 30, 9, 9, 6, 5, 3, 6, 3 in the 91 patients. Cases with abdominal infection was 10 in the 31 patients who were admitted from April 2004 to March 2014, versus 33 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=4.24, P<0.05). Cases dead during the postoperative 90 days was 3 in the 31 patients who were admitted from April 2004 to March 2014, versus 0 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( P<0.05). (3) Post-operative pathological examinations. Of the 91 patients, cases with Bismuth type as type Ⅰ?Ⅱ, type Ⅲ, type Ⅳ, cases with T staging as Tis stage, T1 stage, T2a?2b stage, T3 stage, T4 stage, cases with N staging as N0 stage, N1 stage, N2 stage, cases with M staging as M0 stage, M1 stage, cases with TNM staging as 0 stage, Ⅰ stage, Ⅱ stage, Ⅲ stage, ⅣA stage, ⅣB stage, cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 46, 30, 1, 9, 25, 30, 26, 49, 36, 6, 85, 6, 1, 7, 13, 58, 6, 6, 63, 28. Cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 16 in the 31 patients who were admitted from April 2004 to March 2014, versus 48, 12 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=9.59, P<0.05). (4) Postoperative prognosis analysis. Of the 91 patients, 3 cases who died within 90 days after surgery were excluded, and the 5-year overall survival rate and median overall survival time of the rest of 88 cases were 44.7% and 55 months. The 5-year overall survival rate was 33.5% in the 28 patients who were admitted from April 2004 to March 2014, versus 50.4% in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=5.31, P<0.05). Results of further analysis showed that the corresponding 5-year overall survival rate of cases without lymph node metastasis was 43.8% in the 16 patients who were admitted from April 2004 to March 2014, versus 61.6% in the 31 patients who were admitted from April 2014 to April 2021. There was a significant difference in the 5-year overall survival rate between these patients without lymph node metastasis ( χ2=3.98, P<0.05). The corresponding 5-year overall survival rate of cases with lymph node metastasis was 18.5% in the 12 patients who were admitted from April 2004 to March 2014, versus 37.7% in the 29 patients who were admitted from April 2014 to April 2021. There was no significant difference in the 5-year overall survival rate between these patients with lymph node metastasis ( χ2=2.25, P>0.05). (5) Influencing factors of postoperative prognosis. Results of multivariate analysis showed that poorly differentiated tumor and R 1 or R 2 resection were inde-pendent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma ( hazard ratio=2.62, 2.71, 95% confidence interval as 1.30?5.29, 1.30?5.69, P<0.05). Conclusions:Compared with traditional surgical diagnosis and treatment, treatment of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment can expand surgical indications, reduce proportion of dead patients within 90 days after surgery, improve proportation of radical resection and long-term survival rate. Poorly differentiated tumor and R 1 or R 2 resection are independent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma.

Objective:To explore the effect and value of the active learning mode based on mind mapping in the teaching of medical service support for major disasters.Methods:A total of 90 undergraduate students of 2016 Clinical Medicine of Naval Medical University were randomly selected as research objects, and they were randomly divided into observation group and control group. The 45 students in the control group used the traditional teaching mode, and the 45 students in the observation group used the mind mapping-based active learning mode for major disaster rescue and medical survice. The teaching time of the two groups was 12 h. The theoretical examination of knowledge and practical skills of the two groups of students were compared after teaching, and the students' satisfaction with the application of mind mapping-based teaching model in the teaching of medical service support for major disaster rescue was investigated. EmpowerStats and R softwares were used for t test and Chi-square test. Results:There were 24 males and 21 females in the observation group, with an average age of (21.40±0.69) years old. There were 22 males and 23 females, with an average age of (21.71±0.55) years old. The theoretical performance of the observation group (91.38±4.37) was significantly higher than that of the control group (84.91±3.98) ( P<0.001), and the practical skill performance of the observation group (92.98±3.24) was significantly higher than that of the control group (87.38±3.80) ( P<0.001). At the same time, the students' satisfaction with teaching effect in the observation group was 82.2% (37/45), which was significantly higher than that in the control group (37.8%, 17/45). Conclusion:The active learning mode based on mind mapping focuses on cultivating students' independent learning, interactive exploration and clinical thinking ability, and has a broad application prospect in the teaching of medical service support for major disasters.

【Objective】 To analyze the implementation and problems in the process of the first policy of serious illness benefits for voluntary blood donors in China, therefore provide reference for other provinces and cities to formulate care policies for voluntary blood donors. 【Methods】 The number of blood donors who received serious illness benefits and the proportion to the total number of blood donors in that year were obtained by Excel, and their basic demographic information, illness and reasons for failing to receive benefits were analyzed. 【Results】 From 2015 to 2019, a total of 198 blood donors applied for serious illness benefits, and 159 received benefits (638 000 yuan), accounting for 0.017% of the total number of voluntary blood donors in Nanjing. The average age of the recipients was 52.66, with the proportion of males (63.5%) higher than that of females (36.5%). 52.8% (the highest proportion) got benefits of 5 000 yuan. 39 applicants failed to obtain serious illness benefits, among which 27 applicants failed during 2017 to 2018 due to unidentifiable funding source. But after Nanjing Blood Donation Regulations clarified the funding sources, the implementation of serious illness benefits policy was continued in 2018. 【Conclusion】 The implementation of serious illness benefits for voluntary blood donors presented the Nanjing municipal government's care for voluntary blood donors. The legalization of this policy is conducive to the continuity and stability of policy implementation. Relevant departments and blood centers should continue to strengthen the policy publicity and make sure the policy is implemented effectively.
