Skeletal muscle fibrosis is one of the main pathological changes of Duchenne muscular dystrophy (DMD),which can affect the regeneration of muscle fiber and promote development of the disease.Its occurrence and development correlate closely with inflammatory cells,fibroblasts,myofibroblasts and cytokines.This article reviews the progress of skeletal muscle fibrosis of DMD

At nasopharyngeal carcinoma high-prevalence area,serum EB virus antibody screening is main method to improve the early diagnosis rate,then further improve the survival rate of patients with nasopharyngeal carcinoma.But there is still wedknesses on nasopharyngeal carcinoma screening protocol.For example misdiagnosis and missed diagnosis are major problems.More intensive screening studies should been done to improved early diagnosis rate.

Objective To explore the C-type fixation in the application of the catheter tunnel peritoneal dialysis. Methods One hundred and twenty patients undergoing peritoneal dialysis were selected from January to December 2014 in Xijin Hospital and were randomly divided into the control group and experiment group. The peritoneal dialysis catheters of the control group were fixed vertically at the tube orifice with surgical tape, while the peritoneal dialysis catheters of the experiment group were fixed horizontally first and then placed with a shape ofC and fixed at the tube orifice with surgical tape. The two groups were compared in terms of tunnel score, infection, tube shedding and pulling-induced stimuli. Result The tunnel score and the cases of infection rate, tube shedding and pulling-induced stimuli in the experiment group were lower and fewer than those of the control group with statistical significance (all P <0.05). Conclusion The type C fixation of tube for peritoneal dialysis can effectively reduce the incidence of infections in patients with peritoneal dialysis tunnel, reduce pulling-induced stimuli, and improve comfort of the patients.

Acute pancreatitis( AP)is a common gastrointestinal emergency,which comprises mild acute pancreatitis ( MAP),moderately severe acute pancreatitis( MSAP)and severe acute pancreatitis( SAP). Most patients with MAP and MSAP present as a mild,self-limiting disease with low morbidity and mortality,however,patients who suffer from SAP will experience serious local and/or systemic complications associated with high mortality. Therefore,early assessment of disease severity is important for clinical management. Procalcitonin( PCT),a pro-peptide of calcitonin,is an inflammatory mediator that can be used to differentiate bacterial and non-bacterial infection. Recently,the effect of PCT on AP has attracted more and more attentions. This article reviewed the advances in studies on PCT and AP.

〔Abstract〕 Based on various visual softwares, the paper mines the data of SCI papers and published patents on Eastern Equine En-cephalitis ( EEE) during 1995-2015.2, analyzes the overall development, patent technology life circle, research area, cooperation and competition among countries/districts, basic information of institutes or outstanding individuals.The characteristics of various visual soft-wares are showed, the libraries should master data mining and information visualization technology, so as to provide consulting service to satisfy the deep level and personalized demands of users.

ObjectiveTo detect the mRNA expression levels of RORγt and Foxp3 genes in peripheral blood mononuclear cells(PBMCs) of children with atopic dermatitis(AD),and to explore their possible roles in the development of AD.MethodsSixty-three children with AD and 54 age-matched normal children were eligible for this study.Real-time fluorescence-based quantitative PCR was carried out to measure the mRNA expressions of RORγt and Foxp3 genes in PBMCs of these subjects.ResultsThe relative expression levels of Foxp3 and RORγt mRNA were significantly higher in children with AD compared with the normal controls (2.4060 ± 0.3355 vs.1.1852 ± 0.4189,t =17.50,P＜ 0.01; 6.9130 ± 0.2046 vs.2.7501 ± 0.2518,t =98.63,P ＜ 0.01 ).A statistical increase was observed in the level of RORγt mRNA in children with severe AD compared with children with mild and moderate AD(7.1203 ± 0.1056 vs.6.8046 ± 0.1731 and 6.8655 ± 0.3671,t =6.61,5.23,both P ＜ 0.01).No significant difference was noted in the expression of RORγt mRNA between children with mild and moderate AD,or in the Foxp3 mRNA expression among children with mild,moderate and severe AD.The severity of AD was positively correlated with the level of RORγt mRNA (r =0.62,P ＜ 0.01 ),but uncorrelated with the level of Foxp3 mRNA(r =0.04,P ＞ 0.05).ConclusionsThe high expressions of RORγt and Foxp3 genes may be involved in the pathogenesis of AD,and the severity of AD is positively correlated with the expression intensity of RORγt gene.

Gastric neuroendocrine neoplasms (G- NEN) is a type of relatively rare and heterogeneous tumors mainly derived from enterochromaffin-like cells (ECL-cells) localized in the gastric mucosa. The incidence of G-NEN has increased over the past few decades, which may contribute to factors such as improved clinical and pathological experience in diagnosing this disease, as well as increased access to endoscopy. The biological behavior, clinicalpathological features and treatment response of G-NEN are different from those of pancreatic or intestinal neuroendocrine neoplasms. The diagnosis of G-NEN mainly depends on endoscopy and pathology. Conventional imaging and somatostatin receptor imaging may help to diagnose the disease stage. Treatment requires a multidisciplinary approach that may include endoscopic resection, surgery, chemotherapy, somatostatin analogues, intervention, PRRT, etc. The present study reviews the relevant guidelines in combination of our experience and research and aims to elaborate the epidemiology, clinical classification, diagnostic modalities and treatment options.

The paper expounds the practical significance of the humanistic quality of medical staff,and probes into the cultivation path according to the problems existing in the humanistic quality of medical staff,aimed at promoting the new health care reform orientation,in order to better practice the modern biological-psychological-social medical model,and to provide a useful reference for constructing harmonious doctor-patient relationship.

Sentinel lymph node biopsy has been proved to be the standard treatment for early breast cancer patients with negative axillary lymph node. The study related to the tracer has become one of the hottest topics in breast cancer research. At present, the biopsy is often performed using the tracer of isotope, blue dye or both of them. However, some deifciencies of the 2 tracers restrained their applications, which resulted that the rate of the procedure is limited to only about 60% of patients in developed countries and less than 5% of patients in China and other developing countries. In recent years, a variety of new tracers have emerged, such as indocyanine green, contrast-enhanced ultra-sound using microbubbles, superparamagnetic iron oxide nanoparticles. In this article, we introduced the characteristics of these 3 substances and reviewed the related research on the new tracers. In conclusion, the new tracers are still in the preliminary stage of research, and further research is needed for clinical application.

In vitro fertilization and embryo transfer(IVF-ET) technology is one of the important means to treat infertility in recent years,although it had made remarkable progress in the field of reproductive medicine,but IVF-ET pregnancy success rate is not very ideal,the reasons that influent the success of IVF-ET include both parents donor of various unfavorable factors and stimulate ovulation itself produces all sorts of malpractices,its influence factors are complicated.In recent years,how to reduce the adverse factors affecting IVF-ET,to improve the success rate of pregnancy of IVF-ET has become the hot topics in the study of domestic clinical intervention in IVF-ET,and the domestic research shown that the quality of the follicle and endometrial environment is the key to determine the success of IVF-ET.
