Objective:To investigate the potential mechanism by which Brucella suis vaccine strain S2 induces the apoptosis of BV-2 microglia cells, and to discover new protein targets for neurobrucellosis treatment. Methods:BV-2 microglia cells were treated with Brucella suis vaccine strain S2 for 0, 3, 6, 12 and 24 h. Western blot assay and RT-qPCR were performed to detect the expression of p-JNK and p53 at protein and mRNA levels in BV-2 microglia cells. Cell apoptosis was measured by flow cytometry. Immunofluorescence was used to analyze nuclear p-JNK. Results:Brucella suis vaccine strain S2 could promote the expression of p-JNK and p53 at both protein and mRNA levels and increase nuclear p-JNK in BV-2 microglia cells. Moreover, it could also induce the apoptosis of BV-2 microglia cells. Conclusions:Brucella suis vaccine strain S2 could promote the apoptosis of BV-2 microglia cells through activating JNK and promoting p53 expression.

Objective To evaluate the status of home medication safety among elderly patients with chronic diseases and analyze its influencing factors in urban and rural areas of Henan Province.Methods Convenient sampling method was adopted.Data was collected through a designed and optimized questionnaire.Pharmacists conducted in-home surveys.Excel and SPSS 26.0 software were used for data analysis.Results A total of 352 valid questionnaires were analyzed.Most respondents were aged 60～70 years,with a female proportion of 56.2%,and 52.0%of them had a junior high school education or lower.The top-ranked chronic diseases were hypertension(62.2%)and hyperlipidemia(33.2%),and 61.1%of patients suffered from multiple chronic diseases.Antipyretic and analgesic drugs were most common in home medicine cabinets(90.1%).The proportion of drugs being stored in accordance with the instructions(46.9%)was slightly low,and 93.8%of the elderly handled expired drugs improperly.Awareness of medication guidance services was low(34.9%).Logistic regression analysis showed that factors such as education level and monthly income had significant effects on the understanding of drug package insert,rational drug storage,proper disposal of expired drugs,and awareness of medication guidance services(P<0.05).Conclusion There are still some potential safety risks in the home medication use of elderly patients with chronic diseases in urban and rural areas of Henan Province.It is necessary to enhance education on drug storage and medication guidance,particularly for low-income and less-educated groups,to improve the safety of home medication use.

Background::Gastric cancer (GC), a malignant tumor with poor prognosis, is one of the leading causes of cancer-related deaths worldwide; consequently, identifying novel therapeutic targets is crucial for its corresponding treatment. NUF2, a component of the NDC80 kinetochore complex, promotes cancer progression in multiple malignancies. Therefore, this study aimed to explore the potential of NUF2 as a therapeutic target to inhibit GC progression. Methods::Clinical samples were obtained from patients who underwent radical resection of GC at Lanzhou University Second Hospital from 2016 to 2021. Cell count assays, colony formation assays, and cell-derived xenotransplantation (CDX) models were used to determine the effects of NUF2 on GC progression. Flow cytometry was used to detect the effect of NUF2 or quercetin on cell cycle progression and apoptosis. A live-cell time-lapse imaging assay was performed to determine the effect of NUF2 on the regulation of mitotic progression. Transcriptomics was used to investigate the NUF2-associated molecular mechanisms. Virtual docking and microscale thermophoresis were used to identify NUF2 inhibitors. Finally, CDX, organoid, and patient-derived xenograft (PDX) models were used to examine the efficacy of the NUF2 inhibitor in GC. Results::NUF2 expression was significantly increased in GC and was negatively correlated with prognosis. The deletion of NUF2 suppressed GC progression both in vivo and in vitro. NUF2 significantly regulated the mitogen-activated protein kinase (MAPK) pathway, promoted G2/M phase transition, and inhibited apoptosis in GC cells. Additionally, quercetin was identified as a selective NUF2 inhibitor with low toxicity that significantly suppressed tumor growth in GC cells, organoids, CDX, and PDX models. Conclusions::Collectively, NUF2-mediated G2/M phase transition and apoptosis inhibition promoted GC progression; additionally, NUF2 inhibitors exhibited potent anti-GC activity. This study provides a new strategy for targeting NUF2 to suppress GC progression in clinical settings.

Objective:To construct an indicator system for the development of nursing disciplines in ClassⅢ Grade A general hospitals.Methods:An initial draft of the indicator system was established through literature research and expert meetings. The Delphi method and purposive sampling were used from January to April 2023 to conduct two rounds of expert consultations with 17 nursing experts from four medical units nationwide and three nursing colleges. The indicators were revised and refined, resulting in the establishment of a nursing discipline construction indicator system for ClassⅢ Grade A general hospitals. The level of expert engagement was represented by the questionnaire recovery rate, expert authority by the expert authority coefficient ( Cr), and the degree of expert opinion coordination by Kendall 's harmony coefficient (Kendall 's W) . Results:The recovery rates for both rounds of expert consultation questionnaires were 100.00% (17/17), with expert Cr of 0.87. The CV values ranged from 0.049 to 0.260 and 0 to 0.140, respectively, while Kendall 's W were 0.221 and 0.257 ( P< 0.01). The final indicator system for the construction of nursing disciplines in ClassⅢ Grade A general hospitals included six primary indicators, 18 secondary indicators, and 63 tertiary indicators. Conclusions:The nursing discipline construction indicator system developed for ClassⅢ Grade A general hospitals in this study is scientific, reliable, and comprehensive. It can provide a reference for the construction of nursing disciplines in Class Ⅲ Grade A general hospitals.

Objective To analyze the differences in aging-related information between Chinese and American drug instruction for common chronic disease in the elderly,and to propose policy recommendations for the aging-related drug instruction in China.Methods Ten common chronic disease treatment drugs for elderly patients were selected,and through the random sampling method,the drug manuals of one domestic manufacturer were randomly selected for each drug by the random number method,and one American drug manual was selected as a sample from the dailymed website,and the information related to elderly people in the various items of the drug manuals was statistically analyzed by using Excel for comparative analysis.The average reading level of the patient version of the U.S.drug instructions was calculated using the Readability Formulas Scoring System;the readability of the Chinese drug instructions was assessed by the Health Education Text Material Suitability Scale.Results Compared with the U.S.drug instruction,the drug instruction for common chronic diseases of the elderly in China were updated less frequently and at a slower pace;the drug instruction with information on medication for elderly patients were fewer than those of the U.S.drug instruction,and the content of the drug instruction was not well documented;and the drug instruction were poorly readable,which was not conducive to the comprehension of the elderly patients.Conclusion China is in urgent need of reforming the aging of drug instructions,and it is recommended that,for chronic disease medications for elderly patients,we should increase the number of clinical trials conducted on the elderly,improve and complete the drug information for the elderly in the drug instructions,and produce"drug instructions for elderly patients"that are suitable for the elderly to read and understand.

ObjectiveTo observe the effect of healthy side tilt training on balance function in patients with Pusher syndrome (PS) after stroke. MethodsFrom February, 2021 to November, 2023, 40 patients with PS after stroke in People's Hospital of Bayingolin Mongolian Autonomous Prefecture were selected. They were divided into control group (n = 20) and experimental group (n = 20) in accordance with the order of the patients' admission. The control group received comprehensive training for paralyzed limbs combined with sitting balance training, and the experimental group received comprehensive training for paralyzed limbs combined with healthy side tilt training, for three weeks. They were assessed with Burke Lateropulsion Scale (BLS), Fugl-Meyer Assessment-Balance (FMA-B) and modified Barthel Index (MBI) before and after treatment. ResultsAfter treatment, BLS score significantly decreased in both groups (t > 12.603, P < 0.001), and was lower in the experimental group than in the control group (t = -2.559, P < 0.05). The scores of FMA-B and MBI were significantly increased in both groups (|Z| > 3.941, |t| > 12.082, P < 0.001), and FMA-B score was higher in experimental group than in the control group (Z = -2.538, P < 0.05). ConclusionComprehensive training for paralyzed limbs combined with healthy side tilt training can effectively improve the balance function and postural control of patients with PS after stroke, and improve the activities of daily living.

Severe muscle injury is hard to heal and always results in a poor prognosis. Recent studies found that extracellular vesicle-based therapy has promising prospects for regeneration medicine, however, whether extracellular vesicles have therapeutic effects on severe muscle injury is still unknown. Herein, we extracted apoptotic extracellular vesicles derived from mesenchymal stem cells (MSCs-ApoEVs) to treat cardiotoxin induced tibialis anterior (TA) injury and found that MSCs-ApoEVs promoted muscles regeneration and increased the proportion of multinucleated cells. Besides that, we also found that apoptosis was synchronized during myoblasts fusion and MSCs-ApoEVs promoted the apoptosis ratio as well as the fusion index of myoblasts. Furthermore, we revealed that MSCs-ApoEVs increased the relative level of creatine during myoblasts fusion, which was released via activated Pannexin 1 channel. Moreover, we also found that activated Pannexin 1 channel was highly expressed on the membrane of myoblasts-derived ApoEVs (Myo-ApoEVs) instead of apoptotic myoblasts, and creatine was the pivotal metabolite involved in myoblasts fusion. Collectively, our findings firstly revealed that MSCs-ApoEVs can promote muscle regeneration and elucidated that the new function of ApoEVs as passing inter-cell messages through releasing metabolites from activated Pannexin 1 channel, which will provide new evidence for extracellular vesicles-based therapy as well as improving the understanding of new functions of extracellular vesicles.
