ObjectiveTo investigate the therapeutic effect of proanthocyanidins （PC） on rats with type 2 diabetes mellitus （T2DM） complicated with cognitive impairment （CI） and to explore its potential mechanism by inhibiting the NOD-like receptor family pyrin domain-containing protein 3 （NLRP3）/cysteine-aspartic acid protease-1 （Caspase-1） pathway. MethodsA T2DM rat model was established by high-fat diet combined with intraperitoneal streptozotocin （STZ） injection. Thirty-six diabetic rats complicated with CI were screened by Morris water maze test and randomly divided into model group， PC low-dose （50 mg/kg） group， PC medium-dose （100 mg/kg） group， and PC high-dose （200 mg/kg） group. Another 9 normal rats served as the normal control group. Each group was administered with the corresponding doses of PC or an equal volume of distilled water by gavage for 8 weeks. After the intervention， spatial learning and memory abilities were evaluated using the Morris water maze test. Fasting blood glucose， body weight， and organ coefficients were measured. Pathological changes in the hippocampus were observed by hematoxylin-eosin （HE） staining. Reactive oxygen species （ROS） levels， as well as levels of inflammatory cytokines tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in hippocampal tissue， were detected by enzyme-linked immunosorbent assay （ELISA）. The protein expression levels of NLRP3， Caspase-1， IL-1β， and IL-18 in the hippocampus were determined by Western blot. ResultsCompared with the normal control group， the model group exhibited significantly increased blood glucose and decreased body weight （P<0.05）. In the Morris water maze test， the model group showed prolonged escape latency， fewer platform crossings， and lower percentages of time and path length in the target quadrant （P<0.05）. Disordered arrangement and pyknotic nuclei were observed in hippocampal neurons. ROS and the levels of TNF-α and IL-1β were elevated， and the protein expression levels of NLRP3， Caspase-1， IL-1β and IL-18 were upregulated （P<0.05）. Compared with the model group， all PC-treated groups， especially the high-dose group， presented dose-dependent improvements in the above indicators， including reduced blood glucose （P<0.05）， improved spatial memory performance in the Morris water maze （P<0.01）， alleviated hippocampal pathological damage， decreased ROS and inflammatory cytokine levels （P<0.05）， and significantly downregulated expression of NLRP3/Caspase-1 pathway-related proteins （P<0.05）. ConclusionProanthocyanidins can ameliorate glycolipid metabolic disorder， visceral organ injury as well as cognitive dysfunction in T2DM rats. The underlying mechanism may be associated with reduced hippocampal ROS levels， inhibition of the NLRP3/Caspase-1 signaling pathway， and attenuated neuroinflammation in the hippocampus， with the optimal effect observed at a dose of 200 mg/kg.

To promote the standardization and normalization of perioperative care for follicular unit extraction(FUE) hair transplantation, ensure treatment efficacy, and align with advancements in the specialty, the Nursing Branch of the Chinese Association of Plastic and Aesthetics organized a panel of domestic experts. By integrating evidence-based medicine with clinical practice experience, and following thorough discussions, these experts developed the Clinical Practice Expert Consensus on Perioperative Nursing Care for Follicular Unit Extraction (2025). This consensus provides a comprehensive overview of hair transplantation, covering preoperative preparation, surgical procedures, intraoperative coordination, postoperative management, and complication prevention and treatment. It serves as a key reference and guide for implementing standardized perioperative nursing care in FUE hair transplantation.

OBJECTIVE:To establish the Evaluation Criteria on Rational Use of Human Serum Albumin(HSA)in our hospi-tal,and to provide refereuce for rational use of HSA. METHODS:Referring to drug utilization evaluation(DUE)criteria of WHO and developed countries,based on the guideline of HSA use,Human Serum Albumin,Non-protein Colloid and Crystalloid Solu-tion Guidelines of USA University Hospital Consortium,Blood Products Prescription Evaluation Guideline of Beijing area,etc., Evaluation Criteria on Rational Use of HAS was established through experts discussion,and the use of HAS in 420 patients of our hospital were evaluated. RESULTS:The Evaluation Criteria on Rational Use of HSA mainly included indication,contraindication, usage and dosage,drug combination,incompatibility,etc. 414 patients (98.57%) detected serum albumin concentration before treatment;167 patients(39.76%)were in line with the indication;56 patients(13.33%)had contraindication in using HSA;352 patients(83.81%)met the criteria in usage and dosage,duration of treatment;there were 17 cases(4.05%)of unreasonable drug combination and 3 cases(0.71%)of incompatibility. CONCLUSIONS:The established criteria has strong practicability,and some problems and insufficiencies can be found in the clinical practice,is conducive to promote rational drug use in the clinic.

Objective To investigate the application effect of occupation recreational therapy in improving the elderly bedridden patients′negative emotions and cognitive function .Methods Totally 82 cases of elderly patients corresponding to diagnosis standards were randomly divided into the control group ( conventional drug treatment and nursing ) and the intervention group ( conventional treatment and occupation recreational therapy) with 41 cases in each group .Before and 6 months after the intervention , we evaluated the bedridden degree, anxiety, depression and cognitive ability with self-rating anxiety scale (SAS), geriatric depression scale (GDS), mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) scales. Results 6 months after intervention , the SAS and GDS score of patients in the control group increased from (53.85±5.659) and (14.56±3.9310) to (56.83±6.245) and (18.44±4.219), and their emotional state was significantly worse ( P<0.05) .The SAS and GDS score of patients in the intervention group dropped from (54.44± 5.496) and (14.29±3.593) to (49.93±5.303) and (10.17±2.999), and their emotional state was significantly better (P<0.05).After intervention, the MMSE scores of patients in two groups were (28.44±2.793) and (28.93±2.849) (P>0.05), while their MoCA scores were (24.90±2.095) and (26.20±1.939) (P<0.05).
