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.

Objective:To explore the characteristic categories of kinesiophobia in postoperative cardiac surgery patients and analyze the influencing factors.Methods:Using the convenient sampling method, a total of 225 inpatients from Cardiothoracic and Vascular Surgery Department of Affiliated Nanjing Hospital, Nanjing Medical University (Nanjing First Hospital) were selected as the research objects from June 2022 to April 2023. The inpatients were investigated by general information questionnaire, Numerical Rating Scale (NRS), Brief Illness Perception Questionnaire (BIPQ) and the Tampa Scale for Kinesiophobia Heart (TSK-SV Heart). The latent profile analysis was used to classify the types of kinesiophobia in postoperative cardiac surgery patients, and the Logistic regression was used to analyze the influencing factors of different categories of kinesiophobia in postoperative cardiac surgery patients.Results:A total of 225 questionnaires were distributed in this study, and 212 valid questionnaires were collected, with an effective response rate of 94.22% (212/225). There are three potential categories of kinesiophobia in postoperative cardiac surgery patients, with the low kinesiophobia group accounting for 30.66% (65/212), the low risk perception high exercise fear group accounting for 48.58% (103/212), and the severe kinesiophobia group accounting for 20.75% (44/212). There were statistically significant differences in cognitive dimension scores, fatigue, sleep quality, postoperative presence of high-risk pipelines, history of cardiovascular surgery, and duration of illness among patients of different potential categories ( P<0.05) . Conclusions:There are three different categories of kinesiophobia in postoperative cardiac surgery patients. Medical staff should develop targeted intervention measures for different categories of patients to assist in reducing exercise fear and promoting cardiac recovery.

Objective:To consolidate the current evidences regarding the efficacy of vitamin D supplementation in age-related sarcopenia.Methods:In this systemic review, a comprehensive literature search of scientific research including journal articles and academic dissertations was performed in prominent databases such as PubMed, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Database platforms, spanning from January 31, 2014 to January 31, 2024. Two search protocols integrating keywords and citation tracking were adopted to ensure comprehensiveness of the literature. Using “vitamin D” “ergocalciferols” “cholecalciferol” “sarcopenia” “muscle mass” “muscle strength” “myopenia” “muscle loss” “muscle reduction” “gait speed” “grip strength” “handgrip” as the main key words, focusing on the systematic reviews, meta-analyses of randomized controlled trials (RCT), and individual RCT, the scientific evidence of individual vitamin D intervention on age-related sarcopenia was evaluated and summarized. Research concerning particular disease conditions, children and adolescents, menopausal women, athletes and other specific populations were excluded.Results:A initial search yielded 2 448 articles in Chinese or English. A total of 8 systemic reviews/meta-analysis and 22 individual RCT literatures were included in the final analysis. Although some earlier lower-quality studies reported subtle improvements in skeletal muscle strength with vitamin D supplementation, high-quality systematic reviews/meta-analysis over the past three years had not shown significant positive effects of vitamin D intervention on sarcopenia and its breakdown parameters, such as skeletal muscle mass, muscle strength, and muscle function. Furthermore, the efficiency was influenced to some extent by the participants′ baseline status, such as muscle health and vitamin D nutritional status.Conclusions:Present evidence does not robustly support the efficacy of sole vitamin D supplement on age-related sarcopenia. High-quality clinical trials are imperative to accumulate more robust evidence in the future.

Objective To establish a new program of blood cell processing apparatus(NGL-BBS)for the preparation of washed mixed plateletsand to study the effect on biological activity of platelets compared with tradi-tional manual method.Methods Mixed concentrated platelets were separated and prepared from whole blood by white membrane method.Blood cell processing apparatus with new program set(experimental group)and manual method(control group)was used for thepreparation of washed mixed platelets.The expression rate of CD62P and CD63 in the two groups of washed mixed platelets was compared by flow-cytometry.Thrombus elastography(TEG)was used to measure and compare the MA value between the two groups.Results The expression rate of CD62P and CD63 in the experimental group was lower than that in the control group(t = 4.11,P<0.01;t = 10.78,P<0.01).TheTEG MA valueof the experimental group was higher than that of the control group(t = 6.67,P<0.01).Conclusion The present study demonstrates that the use of NGL-BBS for the preparation of washed mixed plate-lets has a lesser impact on biological activity compared to manual preparation methods.

Objective To explore the value of the combination of serum hemoglobin A1c(HbA1c),Alarin and Ficolin-3 in predicting adverse pregnancy outcomes in patients with gestational diabetes mellitus(GDM).Methods From March 2021 to March 2023,129 GDM patients who underwent prenatal examination and hospital delivery in Yantai Yeda Hospital were collected as the GDM group,while 133 pregnant women with normal glucose tolerance test results were regarded as the control group.Fully automated glycated hemoglobin analyzer was applied to detect serum HbA1c level.Enzyme linked immunosorbent assay(ELISA)was applied to detect serum Alarin and Ficolin-3 levels.Pearson method was used to analyze the correlation between serum HbA1c,Alarin,Ficolin-3 levels and 2 hour postprandial glucose(2 h PG),fasting blood glucose(FBG)and homeostasis model assessment method for insulin resistance(HOMA-IR)in GDM patients.Logistic regression was applied to analyze the relationship between HbA1c,Alarin,Ficolin-3 levels and adverse pregnancy outcomes in GDM patients.Receiver operating characteristic(ROC)curve was plotted to analyze the value of serum HbA1c,Alarin and Ficolin-3 levels in predicting adverse pregnancy outcomes in GDM patients.Results The 2 h PG,FBG,HOMA-IR,and serum HbA1c,Alarin,and Ficolin-3 levels were significantly higher in the GDM group than those in the control group(P＜0.05).The serum levels of HbA1c,Alarin and Ficolin-3 were positively correlated with 2 h PG,FBG and HOMA-IR in GDM patients(P＜0.05).The serum HbA1c,Alarin and Ficolin-3 levels were greatly higher in GDM patients with poor blood glucose control than those in GDM patients with good blood glucose control(P＜0.05).The above levels of three indicators in GDM patients with adverse pregnancy outcomes were significantly higher than those in GDM patients without adverse pregnancy outcomes(P＜0.05).Elevated levels of HbA1c,Alarin and Ficolin-3 were independent risk factors for adverse pregnancy outcomes in GDM patients(P＜0.05).The area under the curves of HbA1c,Alarin and Ficolin-3 alone and in combination were 0.840,0.865,0.815 and 0.979,respectively in predicting adverse pregnancy outcomes in GDM patients.Conclusion The serum HbA1c,Alarin and Ficolin-3 levels are abnormally elevated in GDM patients,and the combined detection of the three can improve the value in predicting adverse pregnancy outcomes.
