The mechanism of Tibetan medicine Zuotangkaca pills (ZTKCW) for the treatment of hypertension was explored by network pharmacology and in vivo experiments. 68 active ingredients of ZTKCW and 518 drug-disease targets were screened by network pharmacology. Eight core components of ZTKCW (vasicolinone, luteolin, (–)-isocorypalmine, esculetin, liquiritigenin, etc.) and eight key targets (AKT1, TNF, IL6, and STAT3, etc.) were screened by network topology analysis. KEGG enrichment analysis showed that the core targets were mainly enriched in lipids and atherosclerosis, JAK/STAT, and inflammation-related pathways. An in vivo experiment was conducted using spontaneously hypertensive rats (SHR), which were gavaged with ZTKCW at doses of 0.41, 0.82, and 1.64 g/kg for 12 weeks, respectively. The results showed that ZTKCW at a dose of 1.64 g/kg significantly reduced both systolic and diastolic pressure in SHR rats and decreased the phosphorylation levels of AKT1, PI3K, STAT3, and JAK2 in the thoracic aorta and heart tissues. This study demonstrates that ZTKCW may exert its antihypertensive effects through PI3K/AKT and JAK2/STAT3 pathways, providing some insights and a theoretical basis for the use of ZTKCW in hypertension.

Objective:To investigate the clinicopathological characteristics of gastrointestinal tumors with SWI/SNF complex deficiency and to perform a prognostic analysis of the patients.Methods:Gastrointestinal tumor cases with SWI/SNF complex deficiency expression diagnosed at the Department of Pathology, Zhongshan Hospital, Fudan University, Shanghai, China from August 2021 to May 2023 were collected. Hematoxylin and eosin (HE) stained slides were reviewed, and immunohistochemical results were analyzed. Clinical and pathological information was recorded, and relevant literature was reviewed.Results:A total of 36 cases of gastrointestinal tumor with loss of SWI/SNF complex expression were identified, including 28 males (77.8%) and 8 females (22.2%). The average age at diagnosis was 70 years (range 48-85 years). Clinical staging showed 3 cases in stage Ⅰ (8.3%), 12 cases in stage Ⅱ (33.3%), 19 cases in stage Ⅲ (52.8%), and 2 cases in stage Ⅳ (5.6%). Complete or partial loss of ARID1A expression was observed in 20 cases (55.6%); complete or partial loss of SMARCA2 expression was observed in 24 cases (66.7%). SMARCA4 exhibited complete loss of expression in 4 cases (11.1%). Eleven cases (30.6%) showed concurrent complete or partial losses of both ARID1A and SMARCA2 expression. Twelve cases (33.3%) had mismatch repair protein deficiency, all of which were characterized by MLH1/PMS2 absence. Mismatch repair protein deficiency was associated with loss of ARID1A expression ( P<0.01). Patients with mismatch repair protein deficiency were also associated with earlier clinical stage and a lower risk of lymph node metastasis compared to the ones with intact mismatch repair proteins ( P<0.05). Conclusions:SWI/SNF complex deficiency in gastrointestinal tumors is associated with dedifferentiation and often accompanied by mismatch repair protein deficiency. Compared to the cases with intact mismatch repair proteins, the cases with defective mismatch repair protein have an earlier clinical stage and a lower risk of lymph node metastasis.

Objective:To explore the competitive attitude of students of medical college and its influencing factors.Methods:A sample of 382 first to third year medical students was selected with the method of random sampling. The questionnaire consists of three parts: demographics, Competitive Attitude Scale of Chinese Version and Jefferson Scale of Physician Empathy. SPSS 25.0 was applied to perform the statistical analysis. Concrete methods that used involved statistical interpretation, Kruskal-Wallis test, Mann-Whitney U test and Spearman rank sum correlation analysis. Results:The benign competitive attitude of students was 51.00(45.00，56.00) and the excessive competitive attitude was 35.00(31.00，38.00). There was a statistically significant difference in the score of benign competitive attitude among medical students of different grades( H=22.31, P<0.001). There were statistically significant differences in the scores of benign competitive attitudes among the medical students who enjoy teamwork ( Z=-4.53, P<0.001), who had role models to follow in the medical field ( Z=-3.99, P<0.001), and who had careful career planning ( Z=-2.19, P=0.029). There were statistically significant differences in the scores of excessive competitive attitudes among the medical students who enjoy teamwork ( Z=-2.47, P=0.014), who had role models to follow in the medical field ( Z=-2.89, P=0.004), and who had careful career planning ( Z=-2.32, P=0.021). There was a weak positive correlation between empathy and benign competitive attitude ( r=0.20, P<0.001), but a negative correlation between empathy and excessive attitude ( r=-0.36, P<0.001). Conclusions:Medical students had a good competitive attitude. Medical college should pay more attention to improving medical students' sense of teamwork, career planning ability and willingness to learn from role models, guide students to develop a benign competitive attitude and focus on improving their professional quality.

Chemical pollution-induced damage to ecosystem function has been a global challenge.The latest"Kunming-Montreal Global Biodiversity Framework"proposed reducing pollution risks to levels harmless to biodiversity and function,placing higher demands on chemical risk management at the ecosystem level.Conventional ecotoxicity tests have focused on single species,only to neglect genetic diversity protection and simplify species interactions.Here,we proposed using environmental RNA(eRNA)and metatranscriptomic analysis to establish a multi-species,multi-biological level chemical pollution ecological risk assessment approach in exposed communities.We reviewed the current status and trends of eRNA in chemical pollution risk assessment and proposed a strategy for bioeffect testing from molecules to communities based on eRNA,constructing ecological risk assessment models for different protection goals.Finally,we summarized the theoretical and technical challenges facing eRNA-based toxicity testing and outlined the future applications of eRNA in capturing real ecological effects of chemical pollution in the field.

Neurosyphilis (NS) is an infectious disease caused by Treponema pallidum invading the central nervous system. It can manifest at any stage of syphilis, and is often misdiagnosed due to its atypical and progressive symptoms. The increasing incidence of NS underscores the necessity for early and accurate diagnosis. Here, we present a case where routine cerebrospinal fluid metagenomic next-generation sequencing (mNGS) was used to diagnose a patient with neurosyphilis. The patient exhibited cognitive impairment and was initially diagnosed with cerebral infarction due to syphilitic cerebral arteritis. Thus, the patient was treated with dual antiplatelet therapy (aspirin and clopidogrel) and statins to stabilize the plaques. Neurosyphilis was treated with penicillin sodium injections, resulting in significant improvement in the patient's mental state. This case is a rare instance of neurosyphilis associated with cerebral infarction. These findings suggest that mNGS is a valuable tool in diagnosing neurosyphilis, potentially improving diagnostic accuracy and patient outcomes.

The number of general clinical research projects filed, the number of submissions and the number of ethics committees filed in the filing system have all increased significantly after the pilot work, with growth percentages of 126%, 141% and 62% respectively. Conclusions:Shandong Province clinical research pilot work has begun to bear fruit, the current clinical research project still exists in the lack of special funding support, perfect service platform and system support and training system to be improved and other issues.

Objective: To investigate whether differences exist in attention deficit hyperactivity disorder (ADHD) and intelligence between children born by cesarean delivery and those born by vaginal delivery. Methods: This retrospective study included singleton children that were born between January 2013 and December 2014. The Chinese version of the Conners’ Parent Rating Scale–Revised (CPRS-48) was required on the probability of psychological and behavioral problems. The China–Wechsler Intelligence Scale for Children (C-WIRS) was used for evaluation of crystallized intelligence and Raven’s Standard Progressive Matrices for evaluation of fluid intelligence. Results: A total of 10,568 valid questionnaires were obtained. CPRS-48 ADHD index and detection rate were higher in cesarean delivery group than those in vaginal delivery group. Cesarean delivery groups had a lower performance intelligence quotient score according to C-WISC. Conclusion Children born by cesarean delivery were more likely to have a risk of ADHD and a lower performance intelligence quotient compared with those born by vaginal delivery.

Objective:To evaluate the safety and effectiveness of the accurate puncture during sacral neuromodulation (SNM) guided with 3D printing navigation template based on reconstruction techniques using fusing sacral CT and MRI images.Methods:Totally 42 patients operated with SNM were selected in Renji Hospital, School of Medicine, Shanghai Jiaotong University from July 2016 to August 2017. The patients were randomly divided into control group ( n=22) and experimental group ( n=20) using random number table. The conventional cross-positioning technique under X-ray was used for puncture during SNM in the control group. While in the experimental group, the sacral CT and MRI images were fused for reconstruction and design of the navigation template, printed by 3D technique for the puncture in SNM. The times of punctures, the average time for puncture operation, the time of intraoperative testing of the stimulator device, the minimum onset voltage of the stimulator, the X-ray radiation dose, postoperative curative effect (rate of secondary transformation) and the incidence rate of complications were compared between the two methods using independent-simple t test or χ 2 test. Results:Compared to control group, fewer times of punctures, shorter time needed for puncture operation, shorter time of intraoperative testing of the stimulator, smaller radiation dose and minimum effective voltage were found in the experimental group ( P<0.05). There were 15 and 16 patients who completed the secondary transformation in the control group and experimental group, and there was no significant difference between the two groups (χ2=0.757, P=0.384). There were 3 cases of complications in the control group, including 2 cases of infection and 1 case of bleeding, while no complications in the experimental group. Conclusions:CT and MRI images fusion reconstruction-guided 3D printing navigation template can help perform accurate and safe punctures in SNM. Compared to conventional puncture positioned under X-ray, it can effectively improve the puncture efficiency, and reduce the radiation dose in the operation.

Objective:To explore the efficacy and safety of intermittent infusion of ilaprazole sodium and high-dose continuous infusion of esomeprazole sodium in preventing rebleeding in patients with peptic ulcer bleeding after successful endoscopic hemostasis.Methods:This is a multi-center, interval randomized, double-blind, double-dummy, parallel controlled study. From March 3rd to June 15th, 2021, 151 patients with high risk of peptic ulcer bleeding and successfully underwent endoscopic hemostasis from 33 hospitals including the First Affiliated Hospital of Zhejiang University School of Medicine were enrolled. Patients were interval randomly divided into the trial group (74 cases) and the control group (77 cases). Patients in the trial group received intermittent intravenous infusion of ilaprazole sodium once daily (20 mg administered as a 60 min intravenous infusion on day 1, and 10 mg administered as a 30 min intravenous infusion on day 2 and 3); patients in the control group received continuous intravenous infusion of esomeprazole sodium for 72 h (esomeprazole sodium 80 mg at first dose in half an hour, and 8 mg per hour continuous intravenous infusion for 71.5 h). After intravenous infusion treatment, patients of both groups were given oral ilaprazole enteric-coated tablets, 10 mg each time, once a day for 4 d. The rebleeding rate after 72 h and within 7 d after treatment and the proportion of patients who received endoscopic retreatment or surgery due to rebleeding within 72 h after treatment were analysised based on the full analysis set (72 cases in the trial group and 75 cases in the control group); and the incidence rate of adverse reactions was observed in the two groups based on the safety analysis set (74 cases in the trial group and 76 cases in the control group). Chi-square test or Fisher exact probability test was used for statistical analysis.Results:There was no rebleeding case in the trial group within 72 h and 1 case of rebleeding within 7 d (1.39%, 1/72). In the control group, there was 1 case of rebleeding (1.33%, 1/75) within 72 h and 4 cases of rebleeding (5.33%, 4/75) within 7 d. There was no significant difference in rebleeding rate either after 72 h or within 7 d after treatment between the two groups (both P>0.05). Within 72 h of treatment, no patients in both groups needed endoscopic or surgical retreatment due to rebleeding. Adverse reactions occurred in 5 cases (6.8%, 5/74) and 6 cases (7.9%, 6/76) in the trial group and control group, respectively, which recovered spontaneously without treatment. No serious adverse reactions occurred in both groups. Conclusion:In patients with high-risk peptic ulcer bleeding with successful endoscopic hemostasis, intermittent intravenous infusion of ilaprazole sodium has similar efficacy and safety as continuous high-dose intravenous infusion of esomeprazole sodium, but the dosage of intermitten regimen is less, the administration is more convenient, and it is worthy of clinical promotion.
