OBJECTIVE To investigate the effects and mechanism of Wenpi tongluo kaiqiao formula (WPTL) against neuronal necroptosis in Alzheimer’s disease (AD) mice based on the Z-DNA binding protein 1 (ZBP1)/mixed lineage kinase domain-like protein (MLKL) signaling pathway. METHODS Forty APP/PS1 transgenic AD mice were randomly divided into model group, WPTL low-dose (WPTL-L) group (10.4 g/kg, calculated by the raw medicine), WPTL high-dose (WPTL-H) group (20.8 g/kg, calculated by the raw medicine) and donepezil hydrochloride group (3 mg/kg), with 10 mice in each group; another 10 C57BL/6J mice were selected as normal control group. Intragastric administration, once a day, for 30 consecutive days. Twenty-four hours after the last administration, Morris water maze test was performed to evaluate learning and memory abilities; the pathological morphology of hippocampal tissues was observed; the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) were determined; the expressions of amyloid precursor protein (APP), Tau protein, and ZBP1/MLKL signaling pathway-related proteins in hippocampal tissues were detected; the positive expression of phosphorylated receptor-interacting protein kinase 3 (p-RIPK3) in the neurons of hippocampal tissues and mRNA expression of ZBP1 were measured in hippocampal tissues. RESULTS Compared with normal control group, the escape latency of mice in model group was prolonged significantly on day 3 to 5 (P<0.05), the times of crossing platform reduced significantly (P<0.05), and obvious pathological changes were observed in the hippocampal tissue. The level of TNF- α, the expressions of APP, p-Tau and ZBP1, the phosphorylation levels of RIPK1, RIPK3 and MLKL, the fluorescence intensity of p-RIPK3 as well as the mRNA expression of ZBP1 were significantly increased (P<0.05), while the serum level of IL-4 was decreased significantly (P<0.05). Compared with model group, above indexes were reversed significantly in administration groups (P<0.05), and pathological damage of hippocampal tissue was alleviated. CONCLUSIONS WPTL can inhibit the ZBP1/MLKL signaling pathway, reduce neuronal necroptosis in AD mice, and inhibit inflammatory responses, thereby improving learning and spatial memory abilities in AD mice.

OBJECTIVE To investigate the efficacy and safety of tirofiban for early neurological deterioration in patients with acute ischemic stroke. METHODS A total of 126 patients with early neurological deterioration of acute ischemic stroke who were admitted to the Department of Neurology, Heji Hospital Affiliated to Changzhi Medical College from January 2022 to December 2023 were selected and divided into observation group and control group according to random number table method, with 63 cases in each group. All patients received standardized treatment such as lipid-lowering and blood pressure-lowering therapy. Based on the standard treatment, patients in the control group additionally took Aspirin enteric-coated tablets 100 mg+Clopidogrel bisulfate tablets 75 mg orally (once a day, for 14 consecutive days). The patients in the observation group received Tirofiban hydrochloride and sodium chloride injection based on the standardized treatment [first intravenous infusion of 0.40 μg/(kg·min) for 30 min, and then continuous intravenous infusion of 0.10 μg/(kg·min) for 47.5 h]; subsequently, patients were given Aspirin enteric-coated tablets (100 mg) and Clopidogrel bisulfate tablets (75 mg) once a day for 14 consecutive days. The clinical efficacy, the National Institutes of Health Stroke Scale (NIHSS) score, modified Rankin Scale (mRS) score, and hemorheological indexes before and after treatment were compared between the two groups, and the adverse reactions were recorded. RESULTS The total effective rate (87.30%) of the observation group was significantly higher than that of the control group (71.43%) (P<0.05). NIHSS scores of the two groups at 1st, 7th and 14th day after treatment, the mRS score at 90th day after treatment, and the platelet aggregation rate, whole blood viscosity, plasma viscosity and fibrinogen at 14th day after treatment were significantly lower than those before treatment in the same group, and the observation group was significantly lower than the control group at the same period (P<0.05). The total incidences of adverse reactions such as nausea, headache, fever, gastrointestinal bleeding, oral and nasal mucosal bleeding and thrombocytopenia in both groups of patients were 28.57% respectively, with no statistically significant difference (P>0.05). CONCLUSIONS For patients with early neurological deterioration in acute ischemic stroke, the addition of tirofiban can accelerate the recovery of neurological function, improve blood hyperviscosity and platelet aggregation, and improve the prognosis of patients with good safety.

OBJECTIVE To investigate the intervention effect and its potential mechanism of Yifei xuanfei jiangzhuo formula by inhibiting mitochondrial fission in a vascular dementia (VaD) model rats. METHODS VaD rat model was established by bilateral common carotid artery ligation. The experimental animals were randomly divided into sham operation group (SHAM), model group (MOD),Yifei xuanfei jiangzhuo formula low-dose group (YFXF-L), Yifei xuanfei jiangzhuo formula high-dose group (YFXF-H), and Donepezil hydrochloride group (positive control), with 9 animals in each group. After 30 days of intervention, the spatial learning memory ability was assessed by Morris water maze experiment; HE staining was used to observe histopathological changes in CA1 area of hippocampus; ELISA was used to detect the levels of serum inflammatory factors [interleukin-1β (IL-1β) and IL-4]; Western blot was used to detect the expressions of heat shock protein 90 (HSP90)/mixed lineage kinase domain-like protein (MLKL)/dynamin-related protein 1 (Drp1) pathway-related proteins, mitochondrial fusion proteins (MFN1, MFN2), and adenosine triphosphate synthase 5A (ATP5A) in hippocampal tissues. The immunohistochemistry was used to detect the level of phosphorylated MLKL (p-MLKL); real-time fluorescence quantitative PCR was adopted to detect mRNA expressions ofHSP90, MFN1, MFN2 and ATP5A. RESULTS Compared with SHAM group, the escape latency of rats in the MOD group was significantly prolonged, the number of crossing the platform was significantly reduced, and the hippocampal tissues showed typical neuronal damage characteristics, the positive expression level of p-MLKL and the serum level of IL-1β significantly increased, while the serum level of IL-4 significantly decreased, the protein and mRNA expression of HSP90, as well as the protein expressions of p-MLKL/MLKL and p-Drp1(Ser616)/Drp1 were all significantly increased in hippocampal tissue, the protein and mRNA expressions of MFN1, MFN2 and ATP5A, and protein expression of p-Drp1(Ser637)/Drp1 were all significantly decreased (P<0.05). After the intervention of Yifei xuanfei jiangzhuo formula, above indicators in each treatment group were all significantly reversed (P<0.05). CONCLUSIONS Yifei xuanfei jiangzhuo formula may alleviate neuronal damage and neuroinflammatory responses in VaD rats by regulating the HSP90/MLKL/Drp1 signaling pathway, inhibiting mitochondrial fission, thereby maintaining mitochondrial dynamic balance and improving mitochondrial function.

Studies on specific transient receptor potential melastatin 2 (TRPM2) channel inhibitors can deepen our understanding of the pathological mechanism of related diseases, and allow discovery of novel, effective targets and drugs for therapy. The development of TRPM2 channel inhibitors can be broadly classified into four categories with distinct characteristics: reutilization and structural modification of homologous ion channel modulators to produce a diverse array of TRPM2 channel inhibitors with strong inhibitory effects; TRPM2 channel inhibitors based on channel gating mechanism with high specificity; inhibitors identified through high-throughput screening with novel chemical structures; inhibitors developed from natural antioxidants with higher safety. In recent years, the application of computer-aided drug design has significantly accelerated the development of TRPM2 channel inhibitors. Several promising compounds such as ZA18, A1 and D9 have been discovered, and it is expected that more potent and selective TRPM2 channel inhibitor scaffolds will be discovered in the future. This article reviews the advances on the studies of TRPM2 channel inhibitors, aiming to provide insights for further research and clinical application of TRPM2 channel inhibitors.

Background::China is one of the countries with the largest burden of gastrointestinal and liver diseases (GILD) in the world. The GILD constitutes various causes of mortality and disability. The study aimed to investigate the trend of GILD in China using the Global Burden of Diseases Study 2019 (GBD 2019) data resources from 1990 to 2019.Methods::The data on the age-standardized mortality rates (ASMR) and disability-adjusted life years (DALYs) for GILD in China from 1990 to 2019 were collected from the GBD 2019 data resources. Furthermore, the ranking of the main causes of deaths and DALYs, as well as the trends of ASMR, DALYs, years of life lost (YLLs), and years of life lost due to disability (YLDs) per 1,000,000 in GILD were reported.Results::The ASMR and DALYs for stomach cancer, liver cancer, and esophageal cancer, which ranked top three among the GILDs from 1990 to 2019, were gradually decreasing. Significant decreases in the ASMR and DALYs were found in diarrheal diseases and acute hepatitis (A, E, and C). However, noteworthy increases were found in those of colon and rectum cancer (CRC) and pancreatic cancer. Trend of DALYs, mortality, and YLLs rates for most of GILD were decreasing from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trend. The DALYs, mortality and YLLs of most GILD diseases showed decreasing trends from 1990 to 2019, except the burden of CRC and pancreatic cancer with an increasing trends.Conclusions::The result of the GBD 2019 showed that the rates of most GILDs decreased in China; however, gastrointestinal and liver cancer, such as stomach cancer still held the top ranking. Furthermore, the shift from infectious diseases to non-communicable causes among GILD burden is occurring.

Placental diseases may affect the outcome of pregnancy and long-term health of the mother and fetus. Fetal fraction is a key indicator for the success of non-invasive prenatal testing, and has been associated with gestational age, body mass index and fetal chromosomal aneuploidies. Many studies have found that fetal fraction is also related to placenta-derived diseases and may become a new predictor for such diseases. This article has summarized the association between the two, with an aim to provide new ideas for the prediction of placental diseases.

ObjectiveTo compare the development status of health facilities in different regions (non-agricultural and agricultural districts)and different types across four dimensions: organizational management, health environment, health activities, and health outcomes, to explore factors that may affect the current development status and summarize effective experiences, and to provide a foundation for the subsequent comprehensive, standardized, and effective promotion of health facility development and tiered and classified management. MethodsInvestigators conducted a health status survey based on the four dimensions for 50 health facilities in 16 districts of Shanghai, representing three types (including government agencies, enterprises, and communities). Evaluation forms were filled out through on-site observation and document reviews, which were developed in accordance with the Shanghai Health Settings Evaluation Standards (for trial implementation in 2019). ResultsThe average total score of health facilities in Shanghai was (88.42±11.93) points, with an overall excellence rate of 86.0%. The excellence rate of each dimension, from highest to lowest, were healthy environment (84.0%), organizational management (82.0%), health activities (78.0%), and health outcomes (44.0%). Health facilities in agricultural districts scored higher in both total score and average score on the organizational management dimension compared to non-agricultural districts. The excellence rate for the organizational management dimension was also higher in agricultural districts than in non-agricultural districts. There was no statistical significance in the total score, the score of each dimension, the overall excellence rate, and the excellence rate of each dimension among different types of health facilities (P>0.05). ConclusionThe development of health facilities among government agencies, enterprises, and communities in Shanghai has begun to yield positive results. Health facilities in non-agricultural districts should actively draw on the experience of those in agricultural districts, particularly in organizational management, adjust development ideas and planning based on their own realities, so as to continuously improve the levels of development.

The development of health-promoting hospitals is an important part of the Healthy China Initiative, facilitating the transformation of medical institutions from a primary focus on medical and surgical treatments to a patient-centered approach prioritizing public health. To promote the scientific, standardized, and sustainable development of health-promoting hospitals, the Shanghai Municipal Center for Health Promotion, together with Shanghai General Hospital and other institutions, has jointly developed the Standards for the Development of Health⁃promoting Hospitals (Standards) in accordance with the principles of scientific rigor, feasibility, and advancing with the times. The Standards outlines the requirements for the development of health-promoting hospitals across four aspects: organizational and institutional guarantees, creation of a healthy environment, implementation of health education and promotion, and evaluation. It is applicable to all levels and types of public medical institutions in Shanghai, and can also be referred to and implemented by other medical institutions. The introduction of the Standards is of great significance for promoting the formation of a long-term mechanism in health-promoting hospitals. This paper introduces the basis, principles, main content, precautions, and implementation suggestions of the Standards. Taking into account relevant policies and standards, it interprets the technical aspects in the process of developing health-promoting hospitals, which is helpful for medical institutions and their management to better understand and apply the standards in their work.

OBJECTIVE To investigate the mechanism of Yifei xuanfei jiangzhuo formula (YFXF) against vascular dementia (VD). METHODS The differentially expressed genes of YFXF (YDEGs) were obtained by network pharmacology. High-risk genes were screened from YDEGs by using the nomogram model. The optimal machine learning models in generalized linear, support vector machine, extreme gradient boosting and random forest models were screened based on high-risk genes. VD model rats were established by bilateral common carotid artery occlusion, and were randomly divided into model group and YFXF group (12.18 g/kg, by the total amount of crude drugs), and sham operation group was established additionally, with 6 rats in each group. The effects of YFXF on behavior (using escape latency and times of crossing platform as indexes), histopathologic changes of cerebral cortex, and the expression of proteins related to the secreted phosphoprotein 1 (SPP1)/phosphoinositide 3-kinase (PI3K)/protein kinase B (aka Akt) signaling pathway and the mRNA expression of SPP1 in cerebral cortex of VD rats were evaluated. RESULTS A total of 6 YDEGs were obtained, among which SPP1, CCL2, HMOX1 and HSPB1 may be high-risk genes of VD. The generalized linear model based on high-risk genes had the highest prediction accuracy (area under the curve of 0.954). Compared with the model group, YFXF could significantly shorten the escape latency of VD rats, significantly increase the times of crossing platform (P<0.05); improve the pathological damage of cerebral cortex, such as neuronal shrinkage and neuronal necrosis; significantly reduce the expressions of SPP1 protein and mRNA (P<0.05), while significantly increase the phosphorylation levels of PI3K and Akt (P<0.05). CONCLUSIONS VD high-risk genes SPP1, CCL2, HMOX1 and HSPB1 may be the important targets of YFXF. YFXF may play an anti-VD role by down-regulating the protein and mRNA expressions of SPP1 and activating PI3K/Akt signaling pathway.

ObjectiveTo explore the clinical efficacy of Gandou decoction in treating Wilson's disease (WD) with dampness heat accumulation accompanied by rapid eye movement (REM) sleep behavior disorder (RBD). MethodFrom April 2019 to August 2023,62 patients with dampness heat accumulation type WD accompanied by RBD who met the inclusion criteria were selected from the Department of Encephalopathy at the First Affiliated Hospital of Anhui University of Chinese Medicine. They were randomly divided into a control group and an observation group with 31 cases each using a computer distributor. The control group received routine copper removal treatment,while the observation group received additional treatment with Gandou decoction on the basis of the control group. Eight days was one course of treatment,totaling three courses. The scores of traditional Chinese medicine syndromes,RBD screening questionnaire (RBDSQ) scores,RBD questionnaire-Hong Kong (RBDQ-HK) scores,polysomnography (PSG) parameters,24-hour urine copper (24 h U-Cu) levels,and non-ceruloplasmin-bound copper (NCC) levels between the two groups before and after treatment were compared,and adverse reactions were observed. ResultSixty trial cases were ultimately completed,with 30 cases in each group. Before treatment,there was no statistically significant difference in various indicators between the two groups, and thus they were comparable. Compared with those before treatment,the traditional Chinese medicine syndrome scores,RBDSQ scores and RBDQ-HK scores of the two groups were significantly reduced,the 24 h U-Cu levels were significantly increased,and the NCC levels were significantly reduced (P<0.05,P<0.01). Compared with the control group, the observation group showed better improvement in traditional Chinese medicine syndrome scores, RBDSQ scores, RBDQ-HK scores, and NCC levels (P<0.05,P<0.01). Compared with those before treatment,the total sleep time (TST),sleep efficiency (SE),sleep/REM latency,the proportion of N1/N2/REM stages,arousal index (ARI),and proportion of phasic electromyographic activity (P-EMG-A) were significantly improved in both groups (P<0.05). Compared with the control group after treatment,the observation group showed more significant improvements in the proportion of TST,SE,REM stages,ARI,and P-EMG-A proportion (P<0.05). ConclusionGandou decoction can not only improve the traditional Chinese medicine syndrome of WD patients with dampness heat accumulation accompanied by RBD but also alleviate their RBD symptoms.
