Inflammatory bowel disease(IBD) is a recurrent chronic nonspecific intestinal inflammatory disease which can be seen at any age.Its pathogenesis is not clear and the incidence is increasing.Intestinal mucosal barrier has the function to isolate intestinal contents and internal environment which can prevent pathogens invade to lamina propria mucosae and maintain organic homeostasis and normal activities.Impairment of intestinal barrier is a key event in various gastrointestinal diseases,such as IBD.The dysfunction of intestinal mucosal mechanic barrier,immunologic barrier and biologic barrier or their interactions all can induce gastrointestinal diseases.Identifying the specific mechanism of intestinal mucosal barrier impairment in pathogenesis of IBD,maintaining and restoring intestinal barrier function is becoming a new strategy in the treatment of IBD.

Wnt signaling pathways is a hot focus in recent years,which plays important regulatory roles in cell proliferation,differentiation and migration.Wnt signaling pathways include classical Wnt signaling pathways and non classical Wnt signaling pathways.Wnt11 is a very important signal molecule in the nonclassical WNT signaling pathways and kidney development,which plays a positive regulatory effect in the development of kidney and become silent in mature kidney.Studies have shown that Wnt11 re-express in the renal fibrosis.This paper discusses the function of the Wnt11 in kidney development and the relationship between Wnt11 and renal fibrosis.

Objective To study the influence of microinflammation factors on the pregnancy outcome in gestational diabetes mellitus (GDM) patients.Methods Forty-eight GDM women with abnormal hsCRP and IL-6 concentration were selected as study group another 36 GDM women with normal concentration as control group.The difference of the two groups in common data and outcomes of pregnancy were retrospectively analyzed.Results There were significant difference in hypertensive disorders,prom,premature delivery,intra-uterine asphyxia,mega fetus,uterine-incision delivery and fetus hypoglycemia hypocalcemia between two groups (P ＜0.05).Conclusions Microinflammation factors have promote influence on the development and outcomes of GDM.Early diagnosis and impose intervention may have positive effect.

Objective:To explore the clinical effect of the emergency surgical treatment of tracheobronchial injury.Methods:11 operative patients with tracheobronchial injury were studied and analyzed.Results:8 patients were emergcntly operated with thoracotomy through tracheobronchial repair.2 cases suffered left inferior pulmonary atelectasis after operation and they healed with sucking sputum through tracheal cannula and positive-pressure ventilation.Right subphrenic abscess occurred in 1 case,and the patient healed with exploratory laparotomy and drainage.There were no death and no bronchopleural fistula or bronchostenosis after operation.Conclution:The emergency tracheobronchial prosthesis through thoracotomy is an important treatment for tracheobronchial injury,which is safe and accompanied with less complications.

Objective:In order to observe the effect of avandia combined with insulin to treat patients with type 2 diabetes mellitus(T2DM). Methods:Seventy two patients whose blood sugar was not controlled well by hypodermic were randomized devided into two groups. Group A was administered insulin alone,Group B was administered insulin and avandia. Fast plasma glucose(FPG),blood sugar 2 hours following meals,HbA1c,plasm insulin and exogenetic insulin doses,etc. Results:FPG,blood sugar 2 hours following meals,HbA1c,plasm insulin level and exogenetic insulin dose were all decreased. Conclusion:Using avandia combined with insulin to treat patients with T2DM can lower blood sugar level of patients and improve insulin resistance. [

Objective:To observe the effects of Lipo PGE1 in Treatment of Diabetic nephropathy(DN).Methods:60 patients with clinical albuminuria were divided randomly into the treatment group and control group,receiving regular treatment.In addition,the cases of treatment group received treatment of PGE1 10?g daily for two weeks.The index of Scr and UAER were observed before and after treatment.Results:The Scr and UAER in treatment group were more decreased than those in control group.Conclusion:Lipo PGE1 is effective in treating Diabetic nephropathy.

The prevalence of asthma in pregnant women appears to be increasing.Pregnant women with uncontrolled asthma may have an increased risk of adverse perinatal outcomes.Optimal management of asthma during pregnancy includes avoiding or controlling asthma triggers,individualized pharmacologic therapy,objective monitoring of lung function,and patient education.Inhaled corticosteroids are the preferred treatment for the management of all levels of persistent asthma during pregnancy.It is safer for pregnant women with asthma to be treated with asthma medications than to have asthma symptoms and exacerbations.The goal of asthma management during pregnancy is to optimize maternal and fetal health.

When the patients with chronic renal failure need drug therapy,we must select the appropriate drugs and adjust the drug delivery methods and dosage according to the renal function of these patients,at the same time we have to consider the factors such as age,sex,weight,combined medication,damage of other organs and so on,the therapeutic drug concentration monitoring should be paid attention to.For patients with blood purification,if the drug mainly removed by the kidneys,adjustments of drug administration must be based on the molecular weight of drug,volume of distribution,protein binding rate,mode of dialysis and hemodialyzer.We must ensure the drug efficacy and reduce the adverse reactions of drugs at the same time in the patients of renal insufficiency.

The enzymological characterizations of site-mutagenized rat recombinant DNA polymerase?, RQ182 and RQ183 were studied The phosphocellulose column chromatographies showed that the mutant and the wild DNA polymerases were all eluted by about 0.5 mol/ L KCI, but the denatured DNA-cellulose chromatographies showed that although the wild enzyme was eluted by 0.35 mol/L KCI, RQ182 and RQ183 were eluted by 0.55 and 0.45 mol/L KCI, respectively, indicating that the binding abilities to DNA of the mutant enzymes were increased. Km values for the substrate (dTTP)of the wild enzyme, RQ182 and RQ183 were determined as 38.5, 34.5 and 111.1 ?mol/L, respectively,and the Km values for the primer (oligo(dT)) were 1.28, 1.96 and 6.58 ?g/ml, respectively. The results showed that the affinities of RQ183 to the substrate and the primer were decreased dramatically. It is suggested that Arg182 and Arg183 were involved in the active site function of DNA polymerase ?, in binding to DNA template, in recognizing of primer, and in binding to and catalyzing of substrates of the enzyme.
