Crohn's disease (CD) is a chronic granulomatous disease with unknown causes, and its incidence shows a rising trend in China. So far there is no way for the complete cure of the disease. Conventional drug therapy has many limitations. The appearance of biological agents brings new treatment options for CD and also initiates a debate over "Step-up" versus "Top-down" strategies. Rational nutrition supplement plays an important role in the comprehensive treatment of CD. This paper reviews the efficacy of conventional drugs, new progress in drug therapy, roles and status of nutritional support, and new treatment strategies for CD.

Circular RNA (circRNA) is widely found in various species' cells.They have several characteristics including structural stability,high expression and expression in a tissue-specific manner.Recent studies have demonstrated that circRNA is a member of competing endogenous RNA (ceRNA).CircRNA regulate the expression of related RNA molecules via binding with target microRNA (miRNA) and play an important role in gene expression and regulation.The finding of circRNAs not only expand our understanding about eucaryon and ceRNA regulation network,but also indicate that circRNA might be a new biological marker for diagnosis and has good application prospects in drug development research,and disease diagnosis and treatment.Because current research on circRNA is still very few,a brief summary about circRNA is presented in this paper for further research.

In the treatment of parenteral nutrition(PN) of preterm infants, parenteral nutrition associated cholestasis(PNAC) is the most common complication. However, the mechanisms of how this complication happens are unknown. This paper summarizes the research reports about PNAC both at home and aboard in recent years and raises various precautions on premature birth avoiding, reasonable feeding, PN projects optimizing and so on.Ursodeoxycholicacid is the first-line drug in the current treatment for PNAC.

Non-Hodgkin's lymphoma (NHL) is a heterogeneous disease from various resources and biological characters. Currently, about 90 ％ of NHL is relative to chromosomal abnormalities. This review emphasizes chromosomal abnormalities in non-Hodgkin's lymphoma, which can not only help understanding NHL genesis,but also is useful for diagnosis on early stage and proper treatment.

Based on the analysis of Medical Independent Colleges,this article is trying to discuss how to set up majors innovatively,reform curriculum and teaching plans effectively By doing this,it aims to set up a bettor education model of Medical Independent Colleges with characteristics of the running of such Medical Independent Colleges.Wishing it can serve as an talent training model for the colleges of the same kind

In recent years the incidence rate of tuberculosis (TB) has gone up.It was estimated that 1/3of people had asymptomatic latent tuberculosis infection globally.The current widespread use of Bacillus calmetteguerin (BCG) vaccine program against tuberculosis in children has a good preventive effect,but due to the limited duration of the immune responses induced by BCG,there also had situation of prevent failure,so researchers begin to explore new TB vaccines,such as live attenuated mutant strains,subunit vaccines and DNA vaccines,and achieved certain results.For the pure protein derivative tuberculosis skin test positive and immunosuppressed children,in addition to active immunization would also need anti-TB medicine for chemoprophylaxis.

Inflammatory bowel diseases (IBD) possibly lie in a dysregulated response of the intestinal mucosal immune system towards intestinal microflora under a combined action of genetic and environmental factors.Mucosal dendritic cells are assumed to play key roles in regulating immune responses in the antigen-riched intestinal environment, either by initiating immune responses or by maintaining tolerance. Defects in this regulation are supposed to lead to IBD. This paper reviews the recent research advances in the relationship between IBD and dendritic cells.

The G protein-coupled receptor, GPR40, is a specific receptor for free fatty acids. Singnaling pathways are activated in islet ?-cells by fatty acids as binding to GPR40. Fatty acids regulate insulin secretion and cause ?-cell hyperplasia through GPR40. GPR40 also mediates responses to antidiabetic drugs like thiazolidinediones. GPR40 agonists and/or antagonists show potential effect in the development of new anti-diabetic drugs.

Objective To investigate the relationship between cytoreduction outcome and staging of ovarian cancer with preoperative blood cell count.Methods The data of 148 ovarian cancer patients from January 2007 to June 2012 were analyzed retrospectively.Clinicopathological and blood cell count data were collected,and benign ovarian tumor group (n =96) as controls.Results Compared to the control group,there were significant differences in the number of white blood cells,neutrophils,lymphocytes,monocytes,platelets,neutrophil to lymphocyte ratio,and platelets to lymphocyte ratio in patients with ovarian cancer (P ＜ 0.05).The same results were also observed in advanced groups and early groups.While between optimal cytoreduction and suboptimal cytoreduction,there were significant differences in platelets,monocytes,neutrophil to lymphocyte ratio,and platelets to lymphocyte ratio (P ＜ 0.05).Conclusions The cytoreduction outcome and pathological staging of ovarian cancer are closely related to the preoperative blood cell count.Blood cell count is important for the identification of benign and malignant ovarian tumors,cytoreduction outcome and the prediction of pathological staging,and may be of significance to the monitoring and prognosis of the disease.

OBJECTIVE:To develop an LC-MS method for the determination of the concentration of duloxetine in human plasma.METHODS:Plasma sample(0.2 mL)was taken,with the protein precipitated twice using acetonitrile.The mobile phase consisted of 20 mmol?L-1 ammonium acetate(pH3.5)-methanol-acetonitrile(38∶20∶42).The sample was separated on a Thermo C18 column with plasma concentrations(time-concentration profile)of duloxetine in 10 healthy volunteers determined by LC-MS after taking a single oral dose of duloxetine enteric-capsule(22.4,44.8 or 67.2 mg).RESULTS:The calibration curve of duloxetine was linear over the concentration range of 0.78～100 ng?mL-1(r=0.999 5)with the recovery at 100.8%,the RSD of intra-day and inter-day at no more than 7.8% and 9.3%,respectively.CONCLUSION:The method developed in our study was proved to be accurate and sensitive,and suitable for the pharmacokinetic study of duloxetine.
