Objective To investigate the relationship between children history of asthma and family history of asthma.Methods Three thousand and five hundred outpatients of asthma children were selected as investigation subjects.Family history of asthma was investigated in the form of questionnaire,and analyzed them from whether or not having family history of asthma,the first and second degree relative having family history of asthma.Results There was no family history of asthma in 1 659 cases(47.4%) and while 1 841 cases had family history of asthma(52.6%).The children who had family history of asthma were slightly more than those who had no family history of asthma.Among the 1 841 cases with family history of asthma,the first degree relatives with family history of asthma were more than those second degree relatives with fa-mily history of asthma.The incidence rate of relatives with family history of asthma on mother′s side was 59.9%,and the incidence rate of the father′s relatives was 40.1%.The incidence rate of mother′s relatives was higher than that of father′s relatives(P

Tumor genesis and development often result from deregulation of important biological pathways at the gene expression level. Although there has been much work focused on searching gene sets using gene expression data or other prior information, proper statistical testing of the gene sets is still an open question. Most studies have expanded the testing method of a single gene into the gene sets. Parametric statistical analysis of gene sets ( p-SAGE ) was presented for determining the significant gene sets or pathways associated with a phenotype of interest. The method was applied to brain tumor experiments to identify many gene sets. Some of the newly discovered gene sets were related to signal transduction and immunity. This simple and effective method gives useful biologically meaningful results.

0.05).Conclusion Low dose mifepristones increase the number of CD_(56)~+ NK cells and the percentage of CD_3~-CD_(56)~+ CD_(16)~-NK subset,which might result in the disturbance of human endometrial immuno-mieroenviromnent during receptive phase and lead to imolantation failure.

The resting cells of Citrobacter freundii 48003 3 expressing high tyrosine phenol lyase activity under the inducing of L tyrosine were used for L DOPA synthesis from catechol, pyruvate and ammonia In this paper, the effects of temperature, pH and substrate concentrations on the synthesis of L DOPA were studied At the optimal conditions of reaction, 9 5g/L of L DOPA was obtained in 12h

Objective To investigate the effect of liraglutide and metformin hydrochioride on overweight diabetic patients because of poor glycemic control.Methods Forty-four overweight patients with poor glycemic control were randomly divided to the control group,the liraglutide group and the metformin hydrochioride group.Patients in control group were given diet and exercise control,in liraglutide group and the metformin hydrochioride group were given subcutaneous injection liraglutide,metformin hydrochioride oral treatment respectively for 12 weeks.Body mass index(BMI),fasting blood glucose (FBG),2-hour postprandial blood glucose (2 hPBG) and glycosylated hemoglobin (HbA1c) were measured.Results Compared with pretreatment,FBG,2 hPBG and HbA1c of patients in liraglutide group and metformin hydrochioride group were lower after treatment,and there was significant difference between the two group and the control group after treatment(P ＜ 0.05).BMI of patients in liraglutide group was (24.61 ± 3.47) kg/m2,lower than of the control group((25.37 ± 4.70) kg/m2,P ＜ 0.05).2 hPBG of patients in the liraglutide group was (7.13 ± 3.85)mtmol/L,lower than that of the metformin hydrochioride group ((8.03 ± 4.33) mtmol/L,P ＜ 0.05).FBG level in metformin hydrochioride group ((6.31 ± 3.45) mmol/L) was lower than that of the liraglutide group ((6.98±2.97) mmol/L),but the difference was not statistically significant(P ＞ 0.05).Conclusion Liraglutide and metformin hydrochioride treatment can effectively reduce weight and blood sugar of the overweight diabetics.The effect of liraglutide to reduce postprandial blood glucose and weight of the patient is more significant than of metformin hydrochioride.

Objective To establish a novel real-time PCR method to detect HCV RNA using Selfreporting duplex mutation primers.Methods The recombinant vector pMD18-T-HCV 5′-NCR was used as the calibrator.The Self-reporting duplex mutation primers were designed according to the gene sequence.And then the PCR reaction system was optimized and evaluated.The specificity,sensitivity and reproducibility of real-time PCR were estimated,The serum specimens from 90 cases(30 cases of HCV,30 cases of other viral hepatitis and 30 healthy volunteers) were tested with this real-time PCR; Results were compared with those obtained using a commercial TaqMan kit.Results The assay was established.It showed linearity over a wide range from 20 - 109 IU/ml.Intra-experimental coefficients of variation(CVs) were 1.37% -4.59%,and inter-experimental CVs were 1.58% -4.81%,respectively.There was no significant difference of HCV genome number tested by the two methods(R2 = 0.95) in 30 hepatitis C patients; HCV DNA was not detected in any serum samples of 30 healthy volunteers by the two methods.The specificity was 100%(60/60).All the samples in patients with clinically confirmed HCV infections showed HCV RNA positive.There wass good correlation between the quantitaive results and results obtained using the commercial TaqMan kit.Conclusions It is demonstrated that real-time PCR is a reliable,accurate and feasible assay for HCV.The establishment of this assay provided alternative technology for clinical diagnosis or therapeutic drug monitoring in the field of HCV infection and epidemiologic survey.

Objective To investigate vascular endothelial growth factor-c (VEGF-C) and vascular endothelial growth factor receptor-3(VEGFR-3) mRNA expression, microvessels density (MVD) and lymphatic microvessels density (LVD) in human hepatocellular carcinoma and normal liver tissue. Try to illuminate the relationship among VEGF-C,VEGFR-3,MVD,LVD and the clinical pathological features of hepatocellular carcinoma. Methods Liver tissue of 60 cases definitely diagnosed as hepatocellular carcinoma and 20 normal cases were collected. VEGF-C and VEGFR-3 mRNA expression were examined by RT-PCR, MVD and LVD were examined by immunohistochemistry staining. Relationship between these indexes and clinical pathological features of hepatocellular carcinoma was also analysed. Results VEGF-C and VEGFR-3 mRNA expression, MVD and LVD in hepatocellular carcinoma were higher than those in normal liver tissue (P<0.01); In hepatocellular carcinoma tissue, expression of VEGF-C mRNA positively related with VEGFR-3 mRNA, MVD and LVD(P<0.01). VEGF-C and VEGFR-3 expression positively related with portal vein tumor thrombus, intrahepatal metastasis and lymph node metastasis (P<0.01). MVD positively related with portal vein tumor thrombus and intrahepatal metastasis (P<0.01). LVD positively related with lymph node metastasis (P<0.01). Conclusion VEGF-C and VEGFR-3 expression increase in hepatocellular carcinoma tissue. They might play roles in tumor invasion and metastasis by inducing angiogenesis and lymphangiogenesis.
