Juvenile systemic sclerosis (SSc) is a chronic connective tissue disease characterized by symmetrical thickening and hardening of the skin,associated with fibrous changes in internal organs.In the last years,several therapies have showed promising beneficial effects in the treatment of SSc.We summarized the recent advances in the anti-inflammation and immunosuppressive therapy,treatment of SSc related vascular diseases,anti-fibrosis therapy as well as prospective treatments.

Central post-stroke pain refers to pain resulting from a primary lesion or dysfunction of the central nervous system after a stroke.The prevalence of central post-stroke pain varies from 8％ to 46％.This article reviews the definition,epidemiology,pathophysiology,clinical features,and treatment of central post-stroke pain.

Objective To analyse the effects of OPG (osteoprotegerin, OPG) at different concentrations on activity of osteoclasts (osteoclasts, OC) , and the relationship between them in physiological activity and function.Methods The bone marrow cells of six weeks old female mice were collected and cultured in vitro on the basis of adding different levels of OPG(10, 20, 50, 100 μg/L).The relationship between OPG and OC were analysed by tartrate resistant acid phosphatase ( TRAP) staining, F-actin cytoskeleton staining and bone resorption pits.Results OC showed adherent growth within 1h cultured, and there were no large multicore OC.Cultured for 5 days, the smaller monocytes gradually began to fusion with each other to form multinucleated cells and showed distinctive characteristics.After three days OPG treatment, the number of multicore cells gradually reduced with OPG concentration increaseing in experimental group, and showing a negative correlation between them(r=-0.516,P<0.05).And there were only a small amount of multinucleated cells at OPG concentration of 50 μg/L.At 20,50 μg/L of OPG concentration, OC number significantly decreased compared with control group (P<0.05), and when the concentration of OPG was 100μg/L, OC number showed significant reduction (P<0 01).the experimental group OPG bone resorption lacunae area, density and decrease the degree were positively correlated with concentration of OPG (r=0.459;r=0.426;r=0.389,P<0.05), and the area had a significant difference when two groups compared.Conclusion The inhibitive effects of OPG on OC function and activation increase with concentration increasing.

We studied and reviewed the PDCA cycle theory related literature, and summarized the research related to PDCA cycle application in the research management in hospitals in china.We also analyzed the present problems and explored future direction of development.

Persistent centrofacial erythema with transient flushing is the most common clinical manifestation of rosacea. However, its pathological mechanisms are poorly understood, and there is a lack of high-level evidence from clinical studies. Based on research progress and clinical experience in China and other countries, the authors emphasize the necessity that facial flushing with erythema should be investigated as an independent clinical phenotype during the study. It is believed that mental stress, anxiety and/or depression may be driving factors in the pathogenesis of facial flushing with erythema. Based on mental factors, it is of potential clinical significance to investigate the relationship of neuroinflammation involved in facial flushing and erythema with skin immunity and blood vessels in rosacea.

Objective To explore the value of electroneurophysiological detection in diagnosis of children progressive muscular dystrophy (PMD).Methods The clinical features and laboratory data were analyzed in 32 children with PMD ,and electromyography(EMG) and nerve conduction velocity(NCV) were performed.Parameters studied included spontaneous activity , duration and amplitude of motor unit potential(MUP),pattern of recruitment as strong contracting,sensory conduction velocity(SCV),motor conduction velocity(MCV), distal latency and distal amplitude. Results The abnormality rates of spontaneous potentials was 49.2% and 80.9% in tibialis anterior.The decrease of duration of MUP was 29.7%-62.4%.Amplitude of strong contracting was significantly decreased.There were different from those in normal children(P

Objective To understand the status of hand hygiene(HH) among patients hospitalized in departments of infectious diseases and their families in Yantai City, and provide reference for HH intervention.Methods Patients and their families(n=221) in departments of infectious diseases of secondary and above levels of hospitals as well as infectious diseases hospitals in Yantai in July-August 2015 were selected for questionnaire survey, education and implementation status of HH were investigated;hand bacteriological sampling was performed on some patients and their families (n=62) to investigate effect of hand-washing.Results 61.99% of patients and their families had received verbal HH education, only 18.55% indicated to have seen health care workers(HCWs) to perform the six step hand-washing method;50.68% of the respondents didn't understand the six step hand-washing method, and 85.52% never performed the six step hand-washing, the main reason is that they didn't know how to perform.93.21% of patients(n=206) and their families believed that hand-washing was important.The cognition of HH opportunities in daily life was relatively higher(61.54%-94.51%),and in hospital environment was relatively lower(36.15%-49.23%),only 36.15% of the families washed hands before left the hospital.Unqualified rate of detection results of sampling of hands of patients with infectious diseases and their families was 83.87%.Conclusion Patients with infectious diseases and their families are deficient in HH knowledge and behavior, medical institutions should carry out systematic and standard HH education to reduce the risk of healthcare-associated infection.
