Objective To investigate JC virus(JCV) infection in kidney transplant recipients and its influence on graft function and also initially explore JCV infection factors. Methods A total of 49 kidney transplant recipients and 24 health examination persons were enrolled in our study, JCV DNA was measured using nested qualitative polymerase chain reaction assays of urine, while CMV DNA was measured by common qualitative polymerase chain reaction assays of urine. JCV infection factors, such as age, male, immunosuppressive therapy, cytomegalovirus(CMV) infection were analyzed by Binary Logistic Regression, and glomerular filtration rate(GFR) was selected as a index of kidney function and the difference of GFR between JCV-infected and non-infected patients was compared using t test. Results JCV was detected in 42.9% of kidney transplant patients and 4.2% health examination persons. CMV infection and Pred + MMF + CsA triple immunosuppressive regimen were found to be the risk factors of JCV infection. No difference of GFR was observed between JCV infected and non-infected patients (86.470 ± 29.990 and 84.060 ± 33. 729 for each; t =0. 259, P =0.797). Conclusion JCV is frequently detected in kidney transplant recipients. CMV infection and using of Pred + MMF + CsA triple immunosuppressive regimen can significantly increase the risk of JCV infection. While, graft function was not influenced by JCV infection in kidney transplant patients.

Objective To systematically evaluate the efficacy of β-blocker in pediatric patients with congestive heart failure and congenital heart disease,and to provide evidence for clinician.Methods Before-and-after self-control study and randomized controlled trials were retrieved from PubMed,EMbase,the Cochrane Library,CNKI,WanFang,VIP databases,and the search time was from the establishment of the database to October 31,2023.All outcomes included left ventricular ejection fraction(LVEF),left ventricular fraction shortening,LVFS),left ventricular end-diastolic dimension(LVDD),Left ventricular end-systolic dimension(LVSD),N-terminal proB brain natriuretic peptide(NT-proBNP),heart rate,blood pressure and cardiac function improvement.Results A total of 20 trials involving 1 068 children with heart failure(dilated cardiomyopathy and endocardial fibroelastosis were included.Meta-analysis results showed that the addition of β-blockers(metoprolol succinate,bisoprolol and carvedilol)on the basis of conventional drug therapy for heart failure had significant effects on LVEF[MD=13.06,95%CI(11.67,14.45),P<0.001],LVFS[MD=6.96,95%CI(6.54,7.37),P<0.001],LVDD[MD=-6.43,95%CI(-7.58,-5.28),P<0.001]and LVSD[MD=-8.30,95%CI(-8.83,-7.76),P<0.001]were significantly improved.In addition,blood pressure,heart rate,NT-proBNP and cardiac function could also be improved.Conclusion The combination regimen of β-blockers on the basis of conventional drug therapy for heart failure can improve cardiac function and symptoms of heart failure in children with congestive heart failure.Therefore,it is recommended that β-blockers should be actively used in the conventional treatment regimen for children with congestive heart failure.

Acupuncture can improve the motor and non-motor symptoms of Parkinson's disease, and the effect of acupuncture combined with drug therapy is better than that of drug therapy alone. The possible mechanism includes inhibiting α-synuclein aggregation, oxidative stress, and neuroinflammation, inhibiting the apoptosis of dopaminergic neurons, and achieving a neuroprotective effect. The points mainly selected for Acupuncture treatment for this disease are Zusanli (ST 36), Yanglingquan (GB 34), Taichong (LR 3), Xuehai (SP 10), and other points. Early use of acupuncture and acupuncture combined with medical treatment strategy is worthy of clinical application.
