ObjectiveTo explore the effect of the medical-community linkage model on activities of daily living, psychological status and motor function of stroke patients in the community. MethodsA total of 60 stroke patients admitted to two community health service centers and their affiliated stations in Fengtai District, Beijing, from January, 2024 to August, 2025 were enrolled and randomly divided into control group (n = 30) and intervention group (n = 30). The control group received routine medicine, dietary care and rehabilitation management, while the intervention group underwent rehabilitation with the medical-community linkage model, for twelve weeks. They were assessed with modified Barthel Index (MBI), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and Fugl-Meyer Assessment (FMA) before and after intervention. ResultsAfter intervention, the MBI, HAMA, HAMD and FMA scores of patients improved in both groups (|t| > 5.599, P < 0.001), and improved more in the intervention group than in the control group (P < 0.05), except MBI. The HAMA and HAMD scores of family members decreased in both groups (|t| > 10.333, P < 0.001), and decreased more in the intervention group than in the control group (t > 5.681, P < 0.001). ConclusionThe medical-community linkage model can further improve the motor function of stroke patients in community, as well as the psychological status of both patients and their family members.

Objective To compare the effect of sodium hualuronate(SH)and platelet rich plasma(PRP)injections in the treatment of glenohumeral joint osteoarthritis(GJO).Methods Sixty-three patients with GJO were randomly assigned to receive either PRP(PRP group,n=29)or SH(SH group,n=34)injec-tions.The injections were administered into the glenohumeral joint under ultrasound guidance.The patients were assessed by the Visual Analogue Scale(VAS),American Shoulder and Elbow Surgeons(ASES)score and modified University of California(UCLA)shoulder joint score before injection and at 1,6,12 months of injection.Results There were no statistically significant differences in the general data between the two groups(P>0.05).Compared with before injection,the VAS scores at 1,6,and 12 months after injection in the two groups were significantly decreased(P<0.05).The VAS score at 12 months after injection in the SH group was significantly increased(P<0.05).The VAS score at 12 months after injection in the PRP group was lower than that in the SH group(P<0.05).The ASES scores showed a significant increase at 1 month after injection compared to before treatment(P<0.05),moreover the ASES scores at 6 months after injection in the PRP group were higher than those in the SH group(P<0.05).Compared with before injection,the modified UCLA shoulder joint scores at 1,6 months after injection in the two groups were significantly in-creased(P<0.05),moreover the scores of the modified UCLA shouder joint scores at 6 months after injec-tion in the PRP group were higher than those in the SH group(P<0.05).Conclusion Pain relief in intraar-ticular injection of PRP in GJO patients is more significant than intraarticular injection of SH,moreover PRP is significantly superior to SH in improving the shoulder joint function of the patients.

BACKGROUND:Croton cream can activate ERK pathways and have anti-apoptotic effects on neuronal cells.It is not clear whether it synergistically exerts anti-apoptotic effects by inhibiting the activation of JNK and p38 pathways. OBJECTIVE:To explore the effects and mechanisms of croton cream on neuronal damage and apoptosis in the ischemic cortex of rats with cerebral ischemia-reperfusion injury. METHODS:(1)Ninety Sprague-Dawley rats were randomly divided into sham operation group,model group,croton cream low-dose group,croton cream medium-dose group,croton cream high-dose group and nimodipine group,with 15 rats in each group.Except for the sham operation group,animal models of middle cerebral artery occlusion were prepared in rats by the thread method.Rats in the three croton cream groups were given 20,40,and 60 mg/kg croton cream,respectively.Rats in the sham operation and model groups were given the same amount of normal saline,once a day,for 7 consecutive days.The optimal concentration of croton cream,namely the high dose of croton cream,was selected based on neurological deficit score,TTC staining,brain tissue water content,hematoxylin-eosin staining and Nissl staining.(2)Another 120 Sprague-Dawley rats were randomly divided into sham operation group,model group,croton cream group,JNK inhibitor group,croton cream+JNK inhibitor group,p38 MAPK inhibitor group,croton cream+p38 MAPK inhibitor group,and nimodipine group,with 15 rats in each group.Animal models of middle cerebral artery occlusion were prepared using the thread method in all the groups except in the sham operation group.Thirty minutes before modeling,10 μL of SP600125(JNK inhibitor)and 10 μL of SB203580(p38 MAPK inhibitor)were injected into the lateral ventricle of the rats,respectively.Rats in croton cream groups were intragastrically given 60 mg/kg croton cream.Seven days later,the JNK/p38 MAPK signaling pathway,apoptosis-related proteins and cell apoptosis were detected by western blot,TUNEL staining and flow cytometry,respectively. RESULTS AND CONCLUSION:(1)Compared with the sham operation group,neurological deficit score,cerebral water content,cerebral infarction volume and apoptosis rate were significantly increased in the model group(P<0.05),where nerve cells showed scattered distribution.Compared with the model group,neurological deficit score,water content of brain tissue and cerebral infarction volume were significantly decreased in the croton cream medium-dose group,high-dose group and nimodipine group(P<0.05),and the pathological morphology of nerve cells was significantly improved.(2)Compared with the JNK inhibitor group,p-JNK/JNK,p-p38/p38 and Bax expressions in rat brain tissue and the apoptotic rate were significantly decreased in the croton cream+inhibitor groups(P<0.05),while the expression of and Bcl-2 was significantly increased(P<0.05).To conclude,croton cream may inhibit the activation of JNK/p38 MAPK signaling pathway and reduce neuronal apoptosis to achieve neuroprotective effects in rats with cerebral ischemia-reperfusion injury.

The changes in intestinal flora are usually associated with different gastrointestinal diseases, and intestinal flora homeostasis can enhance immune tolerance and regulate intestinal immune balance.Previous studies have found that the increase of the relative abundance of Bacteroides fragilis (B.fragilis) in Bacteroides intestinalis can significantly enhance the expression of intestinal regulatory T cells (Treg) and anti-inflammatory cytokines, thus alleviating intestinal inflammation.However, the mechanism of B.fragilis regulating intestinal immunity is still unclear.In this study, an acute colitis model was constructed by giving 3% DSS in drinking water solution to SPF-grade C57BL/6 mice for 7 days, and exogenous supplementation B.fragilis was given to mice by gastric gavage to study its regulatory effect on intestinal immunity and its mechanism of action.The results showed that B.fragilis could improve the intestinal flora disorder in mice with colitis and increase the content of short-chain fatty acids (SCFAs), the main metabolite of the intestinal flora.By extracting mouse tissue lymphocytes, naive CD4+ T cells, and liposome-modified siRNA knockdown mouse Smad3, it was further discovered by flow cytometry that B.fragilis induced the expression of intestinal Treg cells and related cytokines through the TGF-β/Smad3 signaling pathway, which enhanced intestinal regulatory immunity and alleviated colitis.It was also found that B.fragilis activated TGF-β by increasing the expression of reactive oxygen species (ROS), thus inducing Treg cell differentiation and playing an immunomodulatory role.

Objective: This study aimed to evaluate the consistency or stability of mental disorders diagnosed in the psychiatry ward setting, investigate factors associated with consistency, and observe the disease distribution over the decade. Methods: A total of 20,359 psychiatric inpatients were included in this retrospective study from June 2011 to December 2020. Diagnoses from the first admission to discharge were evaluated to determine the diagnostic consistency during hospitalization. Readmissions were selected as the subgroup, whose first and last discharge diagnoses were compared to analyze the relatively long-term diagnostic stability. Demographic and clinical characteristics were collected to identify predictors of diagnostic discrepancy. Results: From 2011–2020, the hospitalization rate decreased from 42.7% to 20.7% for schizophrenia and grew from 13.3% to 23.8% for depression. Diagnoses were retained by 92.6% of patients at their first discharge diagnosis, ranging from 100% for disorders of psychological development to 16.3% for unspecified mental disorders. About 33.9% of diagnostic conversions were to bipolar disorder in patients having inconsistent diagnoses. However, among rehospitalizations, the diagnostic stability notably dropped to 71.3%. For rehospitalizations, mood disorders and schizophrenia spectrum disorders were relatively stable diagnoses categories, with 72.6% to 76.7% of patients receiving the same diagnosis, although results of specified diagnoses within these categories ranged from 5.9% to 91.0%. Except for mood disorders and schizophrenia spectrum disorders, the diagnoses of all other categories were below 70%. Long lengths of hospitalization and old age were associated with short-term diagnosis alterations. Conclusion Longitudinal follow-up and integration of multiple aspects of information are essential for accurate diagnosis.

Objective:To evaluate the efficacy and safety of transhepatic arterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKI) and programmed death-1 (PD-1) inhibitors in the treatment of patients with initially unresectable hepatocellular carcinoma.Methods:The clinical data of 42 patients with initially unresectable hepatocellular carcinoma who were admitted to the Department of Hepatobiliary and Pancreatic Surgery of the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were included. There were 31 males and 11 females, with a median age of 56 years old (range, 45-72 years old). All patients received TACE+ TKI+ PD-1 inhibitor combined treatment. The systemic treatment cycles were calculated by the regimen of immunotherapy. The timing of local treatment depends on tumor size, blood supply and treatment response. Patients were followed up through hospitalization, outpatient visits and telephone review. The Kaplan-Meier curves were obtained for survival analysis.Results:The dosing cycle to achieve optimal imaging response in the patients was 4 (3, 7) [ M( Q1, Q3)], with a systemic treatment time of 141 (65, 194) d [ M( Q1, Q3)] and 2 (1, 3) times [ M( Q1, Q3)] of local treatments. All patients were evaluated by modified response evaluation criteria in solid tumors criteria after treatment, including nine patients with complete response (CR), 21 with partial response, eight with stable disease, and four with progressive disease. Objective response rate and disease control rate were 71.4% (30/42) and 90.5% (38/42), respectively. Treatment-related adverse reactions occurred in 85.7% (36/42) of patients and grade Ⅲ or Ⅳ adverse reactions occurred in 16.7% (7/42). There was no level Ⅳ adverse reactions. All adverse reactions were controlled after dose reduction and symptomatic treatment. Thirteen patients (31.0%, 13/42) redeemed resectable after treatment and underwent radical surgery. Seven patients had pathological CR after surgery. In two patients, the pathological residual cancer tissue was less than 10%. The cumulative overall survival rates of the 42 patients at 6 months, 1 year, 1.5 years after treatment were 100%, 91.7%, and 65.0%, respectively. The postoperative 1-year survival rate of patients undergoing surgery after successful conversion was 83.3%. Conclusion:This study preliminarily showed the safety and efficacy of TACE, TKI, and PD-1 inhibitor combined therapy in patients with initially unresectable hepatocellular carcinoma.

Objective:To analyze the effect of Croton leaf on ERK1/2 pathway in hippocampal of rats with cerebral ischemia-reperfusion.Methods:A total of 216 SD male rats were divided into sham operation group, model group, nimodipine group, low-dose, medium-dose and high-dose groups of croton leaf according to random nubmer table method, with 36 rats in each group. The MACO model of rats was prepared by the method of wire embolization. The high, medium and low dose groups were intragastrated with the water decoction 0.06 g/ml, 0.12 g/ml and 0.18 g/ml of Croton leaf; nimodipine group was intragastrated with nimodipine suspension 1.08 g/L; sham operation group and model group were intragastrated with equal volume of normal saline. Garcia JH score was used to conduct neurological function score, and HE staining was used to observe the morphology of hippocampal neurons after 7 days of continuous administration. Apoptosis of hippocampal CA3/DG region was detected by TUNEL assay. Western Blot was used to detect the expression of ERK1/2 and p-ERK1/2 proteins.Results:Compared with the model group at simultaneous point, the neurological function scores of low-dose, medium-dose and high-dose groups of Croton leaf increased ( P<0.01), the number of apoptotic cells decreased ( P<0.01), the expression of p-ERK1/2 / ERK1/2 [1 d: (0.22±0.03, 0.34±0.02, 0.46±0.01 vs. 0.19±0.02); 3 d: (0.38±0.02, 0.50±0.02, 0.68±0.02 vs. 0.27±0.02); 7 d: (0.29±0.03, 0.43±0.02, 0.59±0.02 vs. 0.21±0.03)] in hippocampus of the low-dose, medium-dose and high-dose groups of Croton leaf significantly increased ( P<0.01). Conclusion:Croton leaf could regulate the expression of ERK1/2 pathway protein upward, effectively improve the neural function and resist the apoptosis of hippocampal CA3/DG area of rats with cerebral ischemia-reperfusion injury.
