OBJECTIVE:To systematically evaluate the efficacy of transcranial direct current stimulation on the motor function of patients with Parkinson's disease,and to compare the efficacy of transcranial direct current stimulation at different targets on the motor function of patients with Parkinson's disease,so as to provide a theoretical basis for the target selection of transcranial direct current stimulation in clinical practice. METHODS:Cochrane Library,PubMed,Web of Science,CNKI,VIP,WanFang Data were retrieved for randomized controlled trials on the improvement of motor function in patients with Parkinson's disease by transcranial direct current stimulation published from the database inception to January 2023.The keywords were"Parkinson,transcranial direct current stimulation"in English and Chinese.The quality of the included studies was evaluated using the Cochrane 5.1.0 risk of bias assessment tool and the PEDro scale.Meta-analysis of outcome indicators was performed using RevMan 5.4 and Stata 17.0 software. RESULTS:Fifteen randomized controlled trials were finally included,and the PEDro scale showed that all were high-quality or very high-quality studies.Meta-analysis showed that transcranial direct current stimulation significantly improved Unified-Parkinson Disease Rating Scale part III score[mean difference(MD)=-2.49,95%confidence interval(CI):-4.42 to-0.55,P<0.05),step frequency score(MD=0.07,95%CI:0.03-0.11,P<0.05)and step speed score(MD=0.02,95%CI:0.00-0.05,P<0.05),but not for Berg Balance Scale scores(MD=2.57,95%CI:-0.74 to 5.87,P>0.05).Network Meta-analysis probability ranking:In terms of Unified-Parkinson Disease Rating Scale part III scores,the probability ranking results of target stimulation efficacy were dorsal lateral prefrontal cortex(52.4%)>primary motor cortex(45.8%)>central point of the brain(1.8%)>conventional rehabilitation(0%);in terms of gait frequency scores,the probability probability ranking results of target stimulation efficacy were cerebellum(50.1%)>central point of the brain(45.8%)>dorsal lateral prefrontal cortex(3.9%)>primary motor cortex(0.2%)>conventional rehabilitation(0%);in terms of gait speed scores,the probability ranking results of target stimulation efficacy were cerebellum(64.8%)>dorsal lateral prefrontal cortex(23.8%)>central point of the brain(9.4%)>primary motor cortex(1.7%)>conventional rehabilitation(0.4%);in terms of Berg Balance Scale scores,the probability ranking results of target stimulation efficacy were cerebellum(77.4%)>dorsal lateral prefrontal cortex(20.7%)>central point of the brain(0.7%)>conventional rehabilitation(0.2%). CONCLUSION:Transcranial direct current stimulation significantly improves motor function of patients with Parkinson's disease,with better motor coordination in the dorsolateral prefrontal cortex and better walking and balance in the cerebellum.

Objective:Based on bioinformatics,new immune-related LncRNAs related to the prognosis of gastric cancer were screened,and a prognostic risk model of immune-related LncRNA was further constructed,in order to be used as a new indicator for early diagnosis and prognostic status of gastric cancer.Methods:The gastric cancer transcriptome data and corresponding clinical prog-nosis data were downloaded from multiple data platforms,and the immune-related LncRNAs of gastric cancer were screened by bioin-formatics methods.Cox regression analysis was used to screen LncRNAs related to immune prognosis in gastric cancer,and LncRNAs related to immune prognosis with independent prognostic significance were identified to construct a prognostic risk model,and the risk score of each patient was calculated.Patients were divided into low-risk and high-risk groups according to the cutpoint.Kaplan-Meier analysis was performed for survival analysis and survival curves were drawn,nomograms were drawn and internal validation was per-formed,and univariate and multivariate Cox regression analysis was performed to analyze the relationship between risk scores and clin-icopathological characteristics and survival prognosis of gastric cancer patients.Results:Three immune prognosis-related LncRNAs(UCA1,MIR4435-1HG,RP11-617F23.1)were identified by Cox regression analysis,and a predictive scoring model was constructed to divide the patients into high-risk group and low-risk group according to the prognosis score.There was a statistically significant dif-ference in the prognosis of patients between the two groups(P<0.05).The multivariate Cox regression analysis risk score was an inde-pendent risk factor for the prognosis of gastric cancer,and the internal verification of the nomogram showed good reliability.Conclu-sion:Three immune-related LncRNAs in gastric cancer are significantly correlated with the prognosis of gastric cancer patients,and the predictive scoring model constructed based on them can effectively predict the prognosis and can be used as their independent prog-nostic biomarkers.

Objective: To investigate the pathological changes and conduct viral gene analysis of OPA and MVD co-occurrence in Inner Mongolia, China. Methods: Using gross pathology, histopathology, immunohistochemistry, ultrastructural pathology, PCR, and sequence analysis, we investigated the concurrent infection of JSRV and MVV in 319 Dorper rams slaughtered in a private slaughterhouse in Inner Mongolia, in 2022. Results: Of the 319 rams included, 3 showed concurrent JSRV and MVV infection. Gross lung pathology showed diffuse enlargement, consolidation, and greyish-white miliary nodules on the lung surface; the trachea was filled with a white foamy fluid; hilar and mediastinal lymph nodes were significantly enlarged. Histopathology results revealed typical OPA and MVD lesions in the lung tissue. Immunohistochemical results were positive for JSRV envelope protein (Env) in the tumor cells and MVV CA in alveolar macrophages. Transmission electron microscopy showed several virions and autophagosomes in the lung tissue, severely damaged mitochondria, and the induced mitophagy. Nucleotide sequences obtained for JSRV env and MVV gag showed the highest homology with the Inner Mongolian strains of JSRV env (JQ837489) and MVV gag (MW248464). Conclusions and Relevance: Our study confirmed that OPA and MVD co-occurrence and identified the pathological changes in Inner Mongolia, China, thereby providing references for the identification of concurrent JSRV and MVV infections.

Objective To investigate the influencing factors of medication adherence among renal transplant recipients taking immunosuppressive drugs. Methods In this study, 377 kidney transplant recipients who received follow-up care in the kidney transplant follow-up center of the Affiliated Hospital of Guizhou Medical University from October 2021 to July 2022 was selected by convenience sampling method. General data questionnaire and Basel Assessment Scale of immunosuppressive drug compliance were used for questionnaire analysis. Results A total of 377 renal transplant recipients were included in this study, including 236 males and 141 females. The overall adherence score was (4.90±1.55), indicating poor adherence. Multivariate Logistic regression analysis revealed that medication adherence among renal transplant recipients taking immunosuppressive drugs was correlated with marital status and postoperative time of renal transplantation. Conclusion Medication adherence among renal transplant recipients taking immunosuppressive drugs needs to be improved, with marital status and postoperative time of renal transplantation being the primary influencing factors.

Objective To investigate the influencing factors of unplanned rehospitalization within one year after surgery among adult renal transplant recipients. Methods The clinical data of 299 recipients who underwent renal transplant surgery in the Department of Organ Transplantation of the Affiliated Hospital of Guizhou Medical University from January 2020 to December 2022 were retrospectively analyzed. The recipients were divided into unplanned rehospitalization group and non-rehospitalization group based on whether they experienced unplanned rehospitalization within one year after surgery. Univariate analysis and binary Logistic regression analysis were performed to explore the influencing factors of unplanned rehospitalization within one year after renal transplantation. Results Among the 299 recipients, 102 experienced unplanned rehospitalization, with an incidence rate of 34.11%. Univariate analysis revealedstatistically significant differences were noted between the two groups in terms of gender, occupational status, preoperative underlying disease, rejection reactions, nosocomial infections, immunosuppressive medication regimens, serum creatinine, cystatin C, serum phosphorus, serum potassium, and initial hospitalization duration (P < 0.05). Binary Logistic regression analysis showed that having ≥3 kinds of preoperative underlying disease (OR=2.122, 95%CI, 1.198 to 3.759) and experiencing rejection reactions (OR=3.162, 95%CI, 1.217 to 8.218) were independent risk factors for unplanned rehospitalization within one year after renal transplantation (P < 0.05). Conclusion The rate of unplanned rehospitalization within one year after surgery is relatively high among adult renal transplant recipients. Having ≥3 preoperative underlying disease and experiencing rejection reactions are independent risk factors for unplanned rehospitalization within one year after surgery. Transplantation healthcare teams can develop corresponding strategies targeting these risk factors to reduce the rate of unplanned rehospitalization and alleviate the burden of disease.

Objective:To analyze the effects of infectious complications [infected pancreatic necrosis (IPN) and extra-pancreatic infection (EPI)] on the outcomes of patients with severe acute pancreatitis (SAP), and evaluate the differences in infection time, infection site and infecting species between SAP patients with infections complications.Methods:The clinical data of 66 SAP patients with combined infectious complications admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were retrospectively analyzed, and SAP patients were divided into IPN group ( n=7), EPI group ( n=14) and co-infection (EPI+ IPN) group ( n=45) according to the type of infection. Whether the study data conformed to a normal distribution was assessed by the Shapiro-Wilk test, normally distributed measures were expressed as mean ± standard deviation ( ± s), and ANOVA was used for comparison between groups; skewed measures were expressed as median (interquartile range) [ M ( Q1, Q3)], and the rank-sum test was used for comparison between groups. Bonferroni correction was used for multiple group comparisons ( P value significance level reduced to 0.017). Quantitative data were compared between groups using the χ2 test or Fisher's exact probability method. Results:There were no statistical differences between the three groups in terms of baseline data at admission (gender, age, etiology, modified CTSI score, degree of pancreatic necrosis, and number of organ failure) ( P>0.05), patients in the EPI group were referred earlier than the other two groups ( P<0.05). In clinical treatment, patients in the IPN group and co-infection group required multiple minimally invasive interventions compared with those in the EPI group ( P<0.05), and the number of patients requiring combined nutritional support, length of intensive care unit stay, and total length of hospital stay were higher in the co-infection group than in the other two groups ( P<0.05). In addition, 360 strains of pathogenic bacteria were cultured in this study, with Gram-negative bacteria being the most common, and patients with SAP were more likely to have EPI in the early stage of disease onset, with bacteremia and respiratory tract infections in the early stage (≤14 d), and bacteremia, urinary tract infections, and catheter-associated infections in the late stage (>14 d). Conclusions:Among patients with SAP, patients in the co-infection group had higher surgical intervention, nutritional support and length of hospital stay than those in the single infection group. It is advisable to prioritize EPI in SAP patients with suspected infections, and the common infectious strains in SAP patients are still predominantly Gram-negative bacteria, and clinicians need to adjust the treatment plan in a timely manner according to the changes in patients′ conditions.

Malignant tumors usually have no obvious clinical symptoms in the early stage. Most patients are already in the advanced stage when they are diagnosed. Some patients have lost the opportunity for operation, resulting in poor prognosis. Therefore, how to find the best therapeutic target for such patients and improve the prognosis of patients has gradually become the focus of scholar′s attention. Recently, Kruppel-like factor (KLF) is a transcriptional regulator that can bind to the target DNA, and its family plays an important role in the occurrence and development of malignant tumors. It has also been confirmed that the KLF family affects the proliferation, differentiation and migration of tumor cells, but the specific mechanism is still not fully elucidate. Consequently, in order to further explored the effect of the KLF family on tumors, this study intends to briefly review the roles and regulatory mechanisms of the KLF family in the cell proliferation, differentiation and migration of malignant tumors, hoping to provide new target for the biological treatment of tumors.
