ObjectiveTo investigate the changes of biochemical parameters in liver disease. MethodsSernm contents of NAG, AFU, LAP, ASTm, GLDH,ADA, and CHE were determined with auto- biochemical analyzer and analyzed in 300 hepatitis patients and 30 healthy subjects. ResultsThe mean values of LAP, ASTm, GLDH,ADA and AFU in acute hepatitis patients were significantly higher than control, positive rate were 93.0% 、81.0%、76. 0% 、82. 0% and 83.2% respectively;The mean values of ADA、AFU and NAG in liver cirrhosis patients were higher than control significantly, positive rate of were 88.5% 、38.2% and 94. 2% respectively;The mean values of ADA and NAG in severe hepatitis patients were higher than control significantly,positive rate are 64. 9% and 95.7% respectively; The mean values of LAP and NAG in liver cancer patients were higher than control significantly, positive rate were75.0% and 88.0% respectively. 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 explore the impact and mechanism of miR-200 b on intestinal epithelial tight junction. Methods The negative-lentivirus and human-miR-200 b-lentivirus were employed to infect the Caco-2 cell thus establishing two stable cell lines which were then stimulated by 10 ng/mL human tumor necrosis factor-α(TNF-α) to establish the model of the intestinal epithelial injury. Those Caco-2 cells were divided into NC, NC+TNF-α, 200b, and 200b+TNF-αgroups.The tight junction permeability was detected by transepithelial electrical resistance (TEER) and Fluorescein isothiocyanate-labeled dextran (FITC-dextran). The protein alterations myosin light chain kinase (MLCK)/phosphorylated myosin light chain (P-MLC) pathways were measured by Western blot analysis. Results Compared to NC group, NC+TNF-αgroup had lower TEER, higher FITC-dextran, and up-regulated expressions of MLCK and P-MLC proteins (P

Objective To observe the effect of application in canicular days on the quality of life and immune substances in patients with allergic rhinitis (AR), and its therapeutic efficacy for AR. Method Sixty-four AR patients were divided into a treatment group of 34 cases and a control group of 30 cases by using the random number table. The treatment group was intervened by acupoint application in canicular days, while the control group was by placebo adhered to the same points. The Short-Form (36) Health Survey (SF-36) and Self-rating Rhinitis Scale (RS) were evaluated before and after the intervention; the serum total immunoglobulin E (T-IgE) and eosinophil cationic protein (ECP) were detected before and after each treatment session, and the changes of the parameters were compared. Result The global scores of SF-36 and RS, and the level of serum ECP were significantly changed after intervention (P<0.05); there was no significant change in serum T-IgE after treatment (P>0.05). Conclusion Application in canicular days can promote the quality of life, improve rhinitis symptoms, and down-regulate the level of serum ECP, indicating that application in canicular days can produce a satisfactory efficacy in treating allergic rhinitis.

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.
