BackgroundRehabilitation for schizophrenia typically relies on pharmacological interventions， yet their efficacy in improving social function and quality of life remains limited. In recent years， non-pharmacological approaches have shown promise in enhancing rehabilitation outcomes. However， research on the effectiveness of psychomotor therapy specifically for young and middle-aged schizophrenic inpatients is limited. ObjectiveTo explore the effects of psychomotor therapy on the rehabilitation of young and middle-aged schizophrenic inpatients， and to provide a reference for treatment strategies. MethodsA total of 104 young and middle-aged schizophrenic inpatients who met the International Classification of Diseases，tenth edition （ICD-10） diagnostic criteria and hospitalized in the Fourth People's Hospital of Wuhu from June 2021 to June 2022 were selected. Patients were randomly divided into two groups of 52 each using random number table method. Both groups received treatment with risperidone tablets （2~4 mg/d） ， along with routine nursing care. Additionally， the research group received an extra 45~55 minutes of psychomotor therapy 2~3 times per week for 12 weeks. The control group received the same psychomotor therapy after the study. Positive and Negative Symptom Scale （PANSS）， Scales of Social-skills for Psychiatric Inpatient （SSPI） and Insight and Treatment Attitude Questionnaire （ITAQ） were used to assess the patients before the intervention and at 4^th， 8^th and 12^th week after the intervention. ResultsThe main effects of intervention at different time points for PANSS positive symptoms， negative symptoms and general psychopathology subscale scores， PANSS total score， SSPI score and ITAQ score were all statistically significant （F=33.989， 204.245， 82.817， 279.596， 26.144， 7.463， P<0.01）. Furthermore， statistically significant between-group differences were observed in PANSS negative symptoms and general psychopathology subscale scores， PANSS total score， SSPI score and ITAQ score （F=30.053， 5.306， 33.417， 33.013， 18.608， P<0.05 or 0.01）. Moreover， the interaction effect of time and group were statistically significant for PANSS positive symptoms， negative symptoms and general psychopathology subscale score， PANSS total score and SSPI score （F=3.472， 9.798， 3.843， 14.390， 20.661， P<0.05 or 0.01）. After 12 weeks of intervention， the research group exhibited statistically significantly lower PANSS total score and subscale scores compared with baseline （P<0.01）， while their SSPI total score was significantly higher than that of control group（P<0.01）. Additionally， compared with the control group， the research group had statistically significantly lower PANSS total score and subscale scores ， while their SSPI score was statistically significantly higher than those of control group（P<0.01）. ConclusionPsychomotor therapy may contribute to the improvement of the psychiatric symptoms and social function in young and middle-aged inpatients with schizophrenia， enhancing their rehabilitation outcomes. ［Funded by Health Commission Scientific Research Project of Wuhu （number， WHWJ2021y073）］

OBJECTIVE To investigate the potential of low-frequency, low-power ultrasound to enhance the transdermal absorption and efficacy of ketoprofen gel. METHODS Ketoprofen gel was used as a model drug to compare the in vitro transdermal permeation of ultrasound treated group and untreated group. Additionally, a rat model of collagen-induced inflammation provided a basis for evaluating pharmacodynamic differences. Pharmacokinetic studies further elucidated the effects of ultrasound on ketoprofen gel's penetration process. RESULTS Ultrasound treatment enhanced the cumulative transdermal permeation of ketoprofen gel by 3.5-fold over 24 hours compared to untreated. Significant pharmacokinetic improvements in AUC0-t from (4289.02±763.58)ng·h·mL−1 to (11301.10±3386.30)ng·h·mL−1 and a reduction in Tmax from (6.0±1.4)h to (3.0±2.0)h. Ultrasound notably improved the gel's anti-inflammatory effects in the rat model, effectively and rapidly reducing inflammation-induced swelling. CONCLUSION Low-frequency, low-power ultrasound can significantly improve the amount and rate of transdermal absorption of ketoprofen gel and enhance its pharmacological potency, from the aspects of skin permeation tests, pharmacodynamic evaluation, and pharmacokinetic studies, which is an effective penetration enhancer for transdermal administration of ketoprofen gel.

Objective:To propose a differential privacy fuzzy C-means clustering algorithm based on Gaussian kernel function(DPFCM_GF)to optimize the data privacy and security issues brought about by data analysis and mining of medical data in the context of big data,and to provide a theoretical basis for data privacy protection.Methods:In order to solve the problem of reducing the accuracy of the algorithm by randomly initializing the fuzzy C-mean membership matrix,the maximum distance method was used to determine the initial center point,the Gaussian value of the clustering center point was used to calculate the privacy budget allocation ratio,and the Laplace noise was added to complete the differential privacy protection and the DPFCM_GF was constructed.The effectiveness of DPFCM_GF was verified by collecting and collating the heart disease,breast cancer,thyroid disease and diabetes public data sets from the machine learning repository of the University of California,Irvine,and the gastric cancer and lung cancer datasets of The Second People's Hospital Huai'an were collected to verify the usability of the DPFCM_GF,and the analysis results were compared with the fuzzy C-means clustering algorithm(FCM)and the differentially private fuzzy C-means clustering algorithm(DPFCM).Results:For public datasets of heart disease,breast cancer,thyroid disease and diabetes,the optimal clustering effects of DPFCM_GF and DPFCM were equivalent to those of FCM;compared with DPFCM,the iteration time of DPFCM_GF was faster,the convergence speed was significant,the difference was statistically significant(t=4.01,4.71,4.01,12.38,P<0.05).For lung cancer and gastric cancer dataset,with the increase of privacy budget ε,the correct recognition rate of DPFCM_GF gradually converged to 91.9%and 93.9%,and the AUC values converged to 0.79 and 0.81,respectively,and when the privacy function ε was 0.1,0.5,1 and 2(ε<3),the DPFCM_GF clustering effect was significantly better than that of DPFCM,and the clustering effect was better and the difference was statistically significant(x2=12.25,87.12,68.58,7.76,P<0.05;x2=4.74,43.51,42.47,4.89,P<0.05).Conclusion:The DPFCM_GF is an effective method for protecting the privacy of medical data,and can also perform data analysis and mining tasks,which has certain research significance and prospects.

OBJECTIVE To screen the optimal compatibility ratio of Gentiana straminea Maxim.(G.S Maxim) and Rhodiola crenulata (Hook. f. et Thoms.) H. Ohba(R. crenulata), and explore its anti-hypoxia effect and possible mechanism through in vivo and in vitro experiments and network pharmacology. METHODS PC12 cells were divided into groups, and the cell hypoxia model was established by Na2S2O4, H2O2 and physical hypoxia methods, and the compatibility ratio of G.S Maxim-R. crenulata was initially screened. Eighty SPF male Kunming mice were randomly divided into blank group, model group, positive group, and different compatibility ratio groups of G.S Maxim-R. crenulata(2:8, 3:7, 4:6, 5:5, 6:4, 7:3, 8:2), with 8 mice in each group. Gastric drug delivery in 15 d in advance, in addition to the blank group, the rest of the groups were normal pressure hypoxia experiments. Groups of mice survival time was recorded. Detected the levels of inflammatory cytokines, MDA content, and SOD activity in the lung tissues of mice in the blank group, model group, positive group, G.S Maxim-R. crenulata 4:6 group and 3:7 group. The anti-hypoxia mechanism of G.S Maxim-R. crenulata was investigated by network pharmacology and molecular docking, and verified by qPCR. RESULTS In vitro experiments showed that G.S Maxim-R. crenulata had better anti-hypoxia activity. In vivo experimental results showed that the combination ratio of G.S Maxim-R. crenulata with 4:6 and 3:7 could significantly improve the survival time of mice, reduce the contents of NF-κB, IL-6, IL-1β and MDA in lung tissue, and increase the content of IL-10 and SOD activity, and the effect of G.S Maxim-R. crenulata 3:7 group was the best. Network pharmacological studies showed that the potential active components of G.S Maxim-R. crenulata in anti-hypoxia might be ursolic acid, oleanolic acid, and ethyl gallate, etc. The core targets included SRC, PIK3CA, MAPK3, etc., and its anti-hypoxia signaling pathways mainly included PI3K-Akt, HIF-1, etc. The results of qPCR showed that G.S Maxim-R. crenulata could increase the expression of PI3K, Akt, mTOR and p62 in the lung tissue of hypoxic mice. Molecular docking verification showed that the core targets SRC, PIK3CA, and p62 had good binding activity with potential active components such as oleanolic acid, kaempferol, ethyl gallate and quercetin. CONCLUSION G.S Maxim-R. crenulata has anti-hypoxia activity, which may be related to PI3K/Akt signaling pathway through anti-inflammatory, anti-oxidative stress and regulation of autophagy.

Proactive personality, caring behavior, transformational leadership, nursing clinical decision-making and educational background were the factors influencing self-efficacy of operating room nurses in stress injury management (all P<0.05). Conclusions:There are three potential profiles of self-efficacy in the management of stress injury in operating room nurses. Nursing managers can give targeted intervention strategies according to different characteristics of nurses to improve their self-efficacy.

Objective:To develop dynamic management strategies for intraoperative acquired pressure injuries (IAPI) in neurosurgery patients and evaluate their implementation effects, so as to provide constructive suggestions for the management of IAPI.Methods:This study was conducted by a non-synchronous before and after control study. From January 2021 to December 2022, 220 patients undergoing neurosurgery in the Second Affiliated Hospital of Guilin Medical College were conveniently selected as the study objects, and divided into the control group and the observation group with 110 patients in each group according to the time of operation. The control group was given routine nursing measures to prevent IAPI, and the observation group was given dynamic management program based on timing theory on bisis of routine nursing. The score of preoperative stress injury,incidence of IAPI and the self-efficacy scores of nurses in the management of stress injury in operating room were compared between the two groups.Results:Before intervention, the scores of preoperative stress injury in control group and observation group were (14.69 ± 2.93) points and (14.78 ± 2.89) points, respectively, with no statistical significance ( t=-0.23, P>0.05).After the intervention, the incidence of IAPI was 3.64%(4/110) in the control group and 0 in the observation group, and the difference was statistically significant ( χ2=4.07, P<0.05). The self-efficacy scores of nurses in the management of stress injury before and after intervention were (29.13 ± 4.87) and (36.41 ± 5.83), respectively, and the difference was statistically significant ( t=-6.21, P<0.05). Conclusions:The implementation of dynamic management strategy of IAPI can effectively reduce the incidence of IAPI in neurosurgery patients and improve the self-efficacy of nurses in operating room.

The importance of gut microbes to human health has gradually attracted attention. With the use of animal models, it has been revealed that maternal microbes during pregnancy could influence their children's health outcomes through shaping their microbial composition and regulating the development of their metabolic and immune system. However, the physiological mechanism of the human body is more complex and is affected by the interaction of multiple factors. The research results obtained from animal models are often inconsistent with human studies. At present, the influence of maternal intestinal microbes during pregnancy on the microbial colonization in their offspring and on a series of children's health outcomes is still unclear. Establishing a sub-cohort to detect the microbiome of the women across pregnancy and of their offspring, and further to integrate with variety of environmental and behavioral exposures can better provide reliable support for the research on the mechanism of children's health and diseases. This paper briefly introduces the research objectives, content, progress, strength and limitations of the sub-cohort study.

Objective:To analyze the characteristics of the ocular vestibular evoked myogenic potential on three different eye positions and to explore the appropriate eye position for oVEMP.Methods:15 patients (30 ears) with vertigo who underwent oVEMP test from December 2017 to May 2018 were selected as the patient group, including seven males and eight females, with an average age of (51±13) years. Another 22 (44 ears) healthy young people were recruited into the control group, including 10 males and 12 females, with an average age of (23±5) years. oVEMPs were measured on the following three eye positions respectively: 30 degrees straight up(upper median position),45 degrees upper right(upper right position), and 45 degrees upper left(upper left position). oVEMP elicitation rate, oVEMP latencies, amplitudes and interaural amplitude asymmetry ratio were analyzed by SPSS 23.0 statistical software.Results:There was no statistical significance ( P>0.05) in the oVEMP elicitation rate, oVEMP latency, amplitude and asymmetry ratio on the three eye positions among the control group, the patient group and the overall subjects. Conclusions:The three eye positions can be used to detect oVEMP in clinic. There is no difference in the extraction rate and waveform characteristics. When one of the eye positions is difficult to gaze or not easy to obtain the coincidence curve, the other two can be used to obtain the ideal oVEMP curves as well.

Objective:This study analyzes the expression level of miR-1180-3p and constructs the regulatory network of relevant ceRNA by integrating the DNA methylation and gene expression profile of hepatocellular carcinoma from the Cancer Genome Atlas (TCGA).Methods:Firstly, the expression level of miR-1180-3p in hepatocellular carcinoma and adjacent tissues was analyzed by TCGA database, and the differential expression of lncrna and mRNA was screened. Secondly, the LncBase database and the TargetScan database were used to predict the relationship between miR-1180-3p and lncRNA and mRNA, and the DNA methylation-mediated lncRNA was screened by the DNA methylation profile of lncRNA. Finally, Cytoscape software was used to construct miR-1180-3p relevant ceRNA network, and WebGestalt website was used to perform GO and KEGG analysis of related mRNA in ceRNA.Results:Compared with patients with low expression of miR-1180-3p (mean overall survival duration, 5.69 ± 0.35 years), patients with high expression of miR-1180-3p had shorter overall survival time (mean overall survival duration, 3.99 ± 0.47 years), indicating that the high expression of miR-1180-3p was hepatocellular carcinoma risk factor affecting the prognosis ( HR = 1.28, 95% CI = 1.1 ~ 1.5, P < 0.01). A miR-1180-3p related ceRNA regulatory network was constructed in this study, which contained 2 lncRNAs (F11-AS1 and LINC01511) and 37 mRNAs. Conclusion:This study has successfully constructed miR-1180-3p relevant ceRNA regulatory network, and DNA methylation-mediated F11-AS1 and F11-AS1/miR-1180-3p/C11of54 ceRNA regulatory axis has played an important role in the occurrence and development of hepatocellular carcinoma.
