Objective To explore the effect of a multicomponent exercise and cognitive stimulation program in elderly patients with mental disorders and sarcopenia,so as to provide references for reducing the risk of falls,preventing and improving sarcopenia,and enhancing cognitive function in patients.Methods The multi-component exercise and cognitive stimulation program was formulated through literature review and expert meeting.In this quasi-experimental study,76 elderly patients with mental disorders and sarcopenia who were hospitalized in a tertiary mental health center in Shanghai from January 2023 to February 2024 were selected as research subjects.They were randomly divided into an experimental group and a control group according to their hospitalization building number(38 cases in each group).The experimental group was treated with multicomponent exercise combined with cognitive stimulation program based on routine nursing,and the control group was treated with routine nursing.The risk of falls,skeletal muscle mass,muscle strength,physical function,cognitive function,and incidence of adverse events were compared between 2 groups after 12 weeks of intervention.Results A total of 75 patients with 37 in the control group and 38 in the experimental group completed the study.The TUG time,6M walking speed and the score of Short Physical Performance Bettery of the experimental group were all lower than those of the control group(P＜0.05),and the scores of skeletal muscle mass,muscle strength,calf circumference,physical function and cognitive function of the experimental group were all higher than those of the control group(P＜0.05).Neither group experienced any adverse events.Conclusion The application of this multicomponent exercise combined cognitive stimulation program developed for elderly patients with mental disorders and sarcopenia can effectively reduce the risk of falls,enhance the skeletal muscle mass and muscle strength and improve the cognitive function in elderly patients with mental disorders and sarcopenia.

AIM To investigate the effects of Changpu Yujin Decoction(CPYJD)on striatal mitophagy and PINK1/Parkin signaling pathway in a rat model of Tourette syndrome(TS).METHODS Thirty-six SPF male SD rats were randomly assigned to the control group(n=9)and the TS modeling group(n=27).Rats in the modeling group received daily intraperitoneal injections of 3,3'-iminodipropionitrile(IDPN)(300 mg/kg)for 7 consecutive days to establish the TS model.Post-modeling,successfully induced TS rats were re-randomized into model group(no treatment),tiapride group(47.91 mg/kg)and CPYJD group(77.28 g/kg).All groups received their respective interventions via intragastric administration daily for 28 days.Following drug administration,behavioral scores were assessed in each group.Pathological alterations in the striatum were examined using HE staining,while ultrastructural changes were evaluated by transmission electron microscopy(TEM).Neuronal apoptosis was quantified via TUNEL staining,and ROS levels in striatum were measured by ELISA.Co-localization of PINK1 and LC3B was assessed using immunofluorescence(IF).Finally,mRNA and protein expressions of PINK1,Parkin,Beclin-1,P62 and LC3B(LC3B-Ⅱ/Ⅰ ratio)were analyzed by RT-qPCR and Western blot.RESULTS Compared to the control group,the model group demonstrated significantly increased behavioral scores(P＜0.01),elevated neuronal apoptosis rate and higher ROS levels in the striatum(P＜0.01);severe neuronal and mitochondrial damage in the striatum;significantly reduced mRNA and protein expressions of PINK1,Parkin,Beclin-1 and LC3B(LC3B-Ⅱ/Ⅰ ratio)in the striatum(P＜0.01);markedly upregulated P62 mRNA and protein expressions(P＜0.01).Compared to the model group,both the tiapride and CPYJD intervention groups exhibited significantly reduced behavioral scores(P＜0.01);decreased neuronal apoptosis rate and lower ROS levels(P＜0.01);improved pathological alterations in the striatal neurons and mitochondria;increased mRNA and protein expressions of PINK1,Parkin and Beclin-1 in the striatum(P＜0.05,P＜0.01);and decreased P62 mRNA and protein expressions(P＜0.01).Furthermore,the rats in the CPYJD group specifically showed elevated LC3B mRNA level and LC3B-Ⅱ/Ⅰ protein ratio in striatum(P＜0.05,P＜0.01).CONCLUSION The effect of CPYJD intervention in TS rats may involve activation of mitophagy through regulation of the PINK1/Parkin signaling pathway,improving mitochondrial function,reducing ROS levels,and thereby protecting neurons.

The operating room is the core settings of various surgical treatments, and exhibits distinct attributes and systemic complexities. Medical staff who work long term in operating rooms face multiple exposures to potential health hazards. Especially with the progress of electrosurgical technology and the frequent use of electrosurgical equipment, the possible health effects of the resulting electrosurgical smoke to those working in operating rooms have gradually attracted attention. This paper reviewed the composition, hazard, exposure risk monitoring, and protective measures of electrosurgical smoke, aiming to deepen the understandings of potential health risks of electrosurgical smoke, improve the self-protection awareness of medical staff, strengthen attention to electrosurgical smoke protection in all hospitals, and ensure the occupational safety of medical staff.

Objective： The aim of this study is to explore the predictive value of biparametric magnetic resonance imaging(bpMRI)for pelvic lymph node metastasis in prostate cancer patients with PSA≤20 μg/L and establish a nomogram. Methods： The imaging data and clinical data of 363 patients undergoing radical prostatectomy and pelvic lymph node dissection in the First Affiliated Hospital of Nanjing Medical University from July 2018 to December 2023 were retrospectively analyzed. Univariate analysis and multivariate logistic regression were used to screen independent risk factors for pelvic lymph node metastasis in prostate cancer, and a nomogram of the clinical prediction model was established. Calibration curves were drawn to evaluate the accuracy of the model. Results： Multivariate logistic regression analysis showed extrocapusular extension (OR=8.08,95%CI=2.62－24.97, P<0.01), enlargement of pelvic lymph nodes (OR=4.45,95%CI=1.16－17.11,P=0.030), and biopsy ISUP grade(OR=1.97,95%CI=1.12－3.46, P=0.018)were independent risk factors for pelvic lymph node metastasis. The C-index of the prediction model was 0.834, which indicated that the model had a good prediction ability. The actual value of the model calibration curve and the prediction probability of the model fitted well, indicating that the model had a good accuracy. Further analysis of DCA curve showed that the model had good clinical application value when the risk threshold ranged from 0.05 to 0.70.Conclusion： For prostate cancer patients with PSA≤20 μg/L, bpMRI has a good predictive value for the pelvic lymph node metastasis of prostate cancer with extrocapusular extension, enlargement of pelvic lymph nodes and ISUP grade≥4.
