ConclusionThe index of LAP and ASTm are valuable markers for diagnosing of acute hepatitis;The index of ADA, ASTm and CHE are valuable marker for diagnosing of liver cirrhosis;The index of ASTm, CHE, AFU and GLDH are valuable marker for diagnosing of severe hepatitis, and AFU and LAP are valuable markers for diagnosing of hepatocellular carcinoma.

Inflammatory bowel disease( IBD)is a chronic and nonspecific intestinal inflammatory disease caused by multiple factors such as environment,genetic susceptibility and immune disturbance. Autophagy plays an important role in cellular homeostasis and immune. Autophagy abnormalities may be involved in the pathogenesis of IBD. Genome-wide association studies(GWAS)have provided compelling evidence that autophagy related genes,including ATG16L1,IRGM and NOD2,are significantly associated with IBD. This article reviewed the abnormal autophagy in pathogenesis of IBD.

Objective To explore the value of combined determination of serum hepatic fibrosis index for evaluation on the degree of liver fibrosis in patients with chronic hepatitis B(HBV).Methods 275 patients with HBV were selected as chronic hepatitis group,which were divided into the mild chronic hepatitis group(75 cases),chronic moderate hepatitis group (72 cases),chronic severe hepatitis group (65 cases),liver cirrhosis group (63 cases) according to the severity of disease.In addition,50 healthy population were selected as the healthy control group.The four liver fibrosis indicators included serum hyaluronic acid(HA),laminin (LN),collagen type Ⅲ (PC Ⅲ),type IV collagen(IV-C) were determined by chemiluminescence immunoassay and compared among the groups,and the diagnostic results of combined different indicators were compared.Results The indexes of HA,PC Ⅲ,IV-C,LN were significantly higher than those of the healthy control group (t =2.567,2.687,2.811,2.741,all P ＜ 0.01).The hepatic fibrosis indexes were increased by with the severity and duration increased gradually (t =2.665,2.787,2.755,2.811,all P ＜ 0.01).The concentration-time curves area (AUC) of PC Ⅲ,Ⅳ-C,LN,HA were 0.680,0.825,0.716,0.826,respectively.Diagnosis value of three combination indicators in HA + PC Ⅲl + Ⅳ-C was highest.Conclusion The chemiluminescence dynamic detection of four liver fibrosis indicators is a good non-invasive detection method for guiding clinical diagnosis on the degree of liver fibrosis.

Objective To observe the effect of montelukast on bronchial asthma and influence on the immune state , in order to provide support for the treatment of montelukast.Methods 92 patients with bronchial asthma in our hospital from December 2014 to January 2016 were selected in the study and randomLy divided into two group.The control group was treated with the conventional therapy of bronchial dilation and glucocorticoid inhalation , and on this basis, the treatment group was loaded with montelukast, 10 mg/times, one times of one day, and the course of treatment was one months.Then the frequency of acute attack of asthma and the number of beta receptor agonist were before and after treatment were recorded , and the lung function the level of T lymphocyte subsets and the levels of inflammatory cytokines before treatment and after treatment were detected , and the difference between the two groups was compared.Results After treatment, t the frequency of acute attack of asthma of day and night and the number of beta receptor agonist of the treatment group were significantly lower than the control group, the FEV1%, FVC% and PEF% of the treatment group were significantly higher than the control group, the level of CD8 + was significantly lower than the control group, the ratio of CD4 +/CD8 + was higher than the control group; the levels of IL-2, INF-γwere higher than the control group, while the levels of IL-4, IL-8 were lower than the control group (P<0.05).Conclusion The montelukast has certain regulation effect on imbalance of CD4 +/CD8 +and Th1/Th2 in children with bronchial asthma, and have a good effect on the prevention of asthma.

Objective · To investigate the effects of ox-LDL on the proliferation of rat theca cells and expression of LXR-α and StAR, two genes associated with androgen biosynthesis. Methods · The expression of LXR-α in the ovarian tissue of rats was determined by immunohistochemistry. Primary theca cells were isolated and collected from rat ovary and cultured in vitro. Furthermore, the theca cells were treated with 25, 50, 100, 150, 200, 300 and 400 mg/L ox-LDL, respectively. The variations in LXR-α mRNA were identified using real-time PCR. MTT assay was performed to detect cell viability. The expression of LXR-α and StAR was measured by Western blotting analysis. Results · The effect of ox-LDL on the proliferation of rat theca cells and the levels of LXR-α and StAR in theca cells was in a concentration-dependent manner. Following exposure to various concentration of ox-LDL for 24 h, the proliferation of theca cells was induced by low concentration of ox-LDL (25-150 mg/L), and 100 mg/L ox-LDL showed the most significant inducing effect. Moreover, the cell survival rate was diminished considerably following with ox-LDL concentration increasing, especially lowered by 400 mg/L ox-LDL. The mRNA level of LXR-α was increased with low concentration of ox-LDL (25-150 mg/L) and the impact of ox-LDL on the induced expression of LXR-α mRNA was considerably distinct at the concentration of 150 mg/L. On the other hand, the expression of LXR-α mRNA was reduced with high concentration of ox-LDL, and the impact of 400 mg/L ox-LDLwas substantially distinct. The protein expression levels of LXR-α and StAR were increased with 150 mg/L ox-LDL, but StAR protein level in 150 mg/L ox-LDL group revealed no significant difference when compared with control group. The expression of LXR-α and StAR protein was significantly inhibited with 400 mg/L ox-LDL in the rat theca cells. Conclusion · Low concentrations of ox-LDL can induce the proliferation of theca cells, and promote the expression of StAR and LXR-α. Whereas, high concentrations of ox-LDL can reduce the cell viability and inhibit the expression of StAR and LXR-α.

Lung cancer has the highest morbidity and mortality rate among malignant tumors. Early diagnosis and effective treat-ment are the keys to improving the survival of lung cancer patients. A type of endogenous, highly conserved, non-coding small mole-cule RNA (i.e., miRNA) was found to play an important role in the occurrence and development of this disease. Research on this molec-ular marker miRNA for the diagnosis, treatment and prognosis of lung cancer has rapidly progressed. This paper reviews the research work on miRNA as a molecular marker in the early diagnosis, treatment efficacy, and prognosis of lung cancer and explores some ques-tions related to this disease.

Objective To study the methods of preparing samples, analyse free radical in smoke of cigarette and the relationship between free radical and the other harmful components in the cigarette smoke. Methods The contents of two types of free radical in smoke of 13 kinds of cigarettes were determined with electron spim resonance(ESR) and the self-made equipment. Results The analytic results showed that the main component was the free radical in gas state in all cigarette samples and it was about 10-30 times higher than the content of free radical in solid state. The content of free radical in gas state of cigarette made in China was lower than that made in foreign country. Conclusion The analysis method using ESR and the self-made equipment will be easily used in the related experiment; The level of free radical in gas and solid state is positively related to the level of tar and nicotine in the cigarette sample of same trademark but it is not the same in the samples of different trademark. Therefore, we can not to infer the content of free radial in cigarette smoke by the content of tar and nicotine in it,especially for the content of free radial in gas state. Using charcoal filter is benefit to reduce the level of free radical in cigarette smoke.
