Objective To establish a method for efficient,accurate genotyping and nucleoside drug-resistant mutation analysis for hepatitis B virus ( HBV ).Methods The 48 HBV serum samples were collected from the Third People's Hospital of Taiyuan from July to August 2011,and HBV DNA were extracted using the commercial kit.The HBV whole genome and P gene were amplified and sequenced.Each HBV sample was genotyped by both constructing phylogenetic trees and genotyping software analysis.The results from two strategies were compared for every sample.Results A total of 48 HBV full genome sequences were identified into 12 B and 36 C genotype's by both constructing phylogenetic trees and genotyping software analysis,which was exactly the same as the analysis using P gene fragment sequencing.Seven forms of nucleoside drug-resistant mutation were found in the P gene for all the samples,with the ratio of 27.1％ ( 13/48 ),in which all the mutation forms were associated with lamivudine or adefovir,and no other nucleotide drugs-related resistance mutations existed.In addition,there were 11 B and 35 C genotype and 2 B/C hybrid type with the analysis using Real-time PCR genotyping for the 48 samples.Conclusion P gene sequencing can be used as a new clinical method for efficient,accurate HBV genotyping and resistant mutation analysis,which provides guidance for hepatitis B treatment.

Objective To investigate the fluorescence quantitative PCR (FQ-PCR) based on TaqMan-MGB( Minor Groove Binder) technique for quantification of fetal DNA in maternal plasma and its variation during pregnancy. Methods Maternal DNA extracted from 237 plasma samples obtained from 30 pregnant women (5-40 gestational weeks and post delivery). The TaqMan-MGB probe and SRY primers were designed to amplify the SRY gene sequence of Y chromosome in maternal plasma by FQ-PCR. Results This system was sensitive enough to detect a male DNA among 20 000 female DNA. Fetal DNA can be detected in maternal plasma as early as 6+6 weeks of gestation and increased with the pregnant progress with the peak level at the third trimester. Between 24- 48 h after delivery, the SRY gene was negative in maternal plasma. The percentage of fetal DNA concentration in maternal total plasma DNA was 4. 88% in the first trimester, 6. 10% in the second and 4. 77% in the third trimester. The SRY positive signal was obtained from samples of 13 women bearing male fetuses and no signal was detected for all of the 17 women bearing female fetuses. Conclusions The FQ-PCR for quantification of fetal DNA in maternal plasma is highly sensitive, specific and reliable. Fetal DNA does present in maternal plasma at a higher concentraton. FQ-PCR may be useful in nonin-vasive prenatal diagnosis.

Objective:To investigate the causes of false-positive anti-HCV in non-syndromic cleft lip and palate with serum chemiluminescence test. Methods:We performed a hospital-based,case-control study of 4 050 patients with non-syndromic cleft lip and palate and 8 547 control patients without cleft lip and palate to evaluate associations between positive anti-HCV and non-syndromic cleft lip and palate. CLIA test were used for detect anti-HCV in control group. RIBA and FQ-PCR were used for confirming the result of the positive samples of CLIA test. CLIA test were used for detect anti-HCV in case group until CLIA test was negative. IgG,RF and ANA were used for case-control comparisons. Results:The detection rate of anti-HCV were higher in the case group than that of control group (P<0. 05). The false-positive rate was 1 percent based on testing of 4 050 patients. These samples were negative after opration 1-19 months. There were no change among IgG, RF and ANA in the false-positivepatients. Conclusion: False-positive anti-HCV in non-syndromic cleft lip was possible associated with abnormal plasma metabolic product. It can be excluded by track monitoring.

Objective:To analyze the value of fine needle aspiration cytology and CT perfusion imaging in differential diagnosis of benign and malignant salivary gland tumors. Methods: Perfusion CT and fine needle aspiration cytology were performed in 36 patients of salivary gland tumors(26 cases in parotid gland, 8 cases in submandibular, 1 case in sublingual gland and 1 case in pars palatalis) and perfusion parameters, including: blood flow(BF), blood volume(BV), mean transit time(MTT), permeability surface(PS). Pathological diagnosis was performed on all salivary gland tumors. Results: 13 cases of 36 patients eventually were diagnosed as malignant salivary gland tumors. The sensitivity, specificity and accordance rate for malignancy of fine needle aspiration cytology were 84.6%(11/13), 95.7%(22/23) and 91.7%(33/36), respectively. The values of BF, BV and PS of the malignant tumors were higher than those of benign tumors significantly(P<0.05). However, the MTT values showed no significant difference between benign and malignant tumors(P>0.05).The sensitivity, specificity, and accordance rate for malignancy of CT perfusion were 92.3%(12/13), 86.9%(20/23) and 88.9%(32/36), respectively. The negative cases of fine needle aspiration cytology can be correctly identified as malignant by CT perfusion imaging. Conclusion: CT perfusion imaging can provide salivary gland tumors with information of microcirculation perfusion. It contributes to the identification of benign and malignant tumors. Paralled with fine needle aspiration cytology can greatly improve the accuracy of salivary gland tumors.

Objective To investigate the detectable rate and correlative factors of behavior problems among Hui nationality left-behind children in Ningxia rural area.Methods 1394 children,between 6 and 15 years old,of which 282 were Hui nationality children and 112 were Hui left-behind children,were selected from six primary schools and two junior middle schools using cluster random sampling method in Yongning,Ningxia.All of them were assessed by the Achenbach 's Child Behavior Checklist (CBCL) and self-designed General Information Questionnaire.Logistic regression method was used to analyze the correlative factors of behavior problems.Results The detectable rate of behavior problems among Hui nationality children between 6 and 15 years old was 31.25％,which was higher than the Han nationality left-behind children' s(17.84％) and Hui nationality nonleft-behind children' s (14.12％).Among the Hui left-behind children,those who between 6 and 11 years old,had been left alone between 5 and 7,and whose parents exchanging ideas with teachers less than one time a month had higher detectable rates (x2 =14.904,6.327,7.904,P ＜ 0.05).Among the Hui ethnic children,the detectable rates of those who between 6 and 11 yeas old were higher than that of the non-left-behind children' s(P ＜ 0.05).Logistic regression analysis showed that Hui ethnic left-behind children between 12 and 15 years old (OR =0.179) and those whose parents contacted with their teachers frequently(OR =0.362) had less possibilities to attach behavior problems.Conclusion The detectable rate of behavior problems among Hui nationality left-behind Children between 6 andl5 years old in Ningxia is higher,and the correlative factors are complex.

Objective To investigate the relationships between depression and life events and coping style of left-behind children in Ningxia rural district.Methods 1455 children,between 7 and 15 years old,of which 643 were left-behind children and 812 were non-left-behind children,were selected from six primary schools and two junior middle schools in Ningxia using cluster-random-sampling.All of them were assessed by the Depression Self-rating Scale for Children (DSRSC),Adolescent Self-rating Life Event Checklist (ASLEC) and Simplified Coping Style Questionnaire (SCSQ).Pearson correlation analysis was used to analyze the correlation between leftbehind children' s depression phenomenon and all items in the questionnaires above,and Hierarchical multiple linear regression were used to analyze the correlative factors associated with depression among left-behind children.Results The detectable rate of left-behind children and non-left-behind children' s depression were respectively 30.30％ and 21.20％,and the former was higher than the later (x2 =15.909,P＜0.01).In the left-behind children group,the depression relevance ratio were significant difference (35.23％ vs.26.52％) between the 7-11 years old group and the 12 to 15 one(P＜0.05).The detectable rate of Han and Hui ethnic children(29.00％ vs.37.14％)had no statistically significance.Except positive replying,left-behind children had got higher scores in all factors of DSRSC,ASLEC and negative replying compared with non-left-behind children.According to the Pearson correlation analysis,the scores of DSRSC had positive correlation with all factors in ASLEC,while had negative correlation with active coping style in SCSQ (P ＜ 0.05).According to hierarchical multiple linear regression,positive replying,passive coping style,health and adaptation and human relationship went into the equation,which were important predictive variables for depression.Conclusion The left-behind children in Ningxia have high detectable rate of depression,and active coping styles are useful buffer for the life events' harmful effects.

Objective To investigate the role of and relationship between reactivity to autologous serum and dermatophagoides farinae (Df) in the pathogenesis of chronic urticaria (CU). Methods Autologous serum skin test (ASST) and skin prick test (SPT) to Df were carried out in 831 patients with CU. The correlation between reactivity to autologous serum and Df was statistically analyzed. Results The positivity rate of ASST and SPT to Df was 51.74% and 64.62%, respectively in the 831 patients. SPT was positive in 56.52% of patients with positive ASST and in 73.86% of those with negative ASST (P ＜ 0.05). In patients with positive ASST, the degree of autologous serum reactivity was negatively correlated with that of reactivity to Df (P ＜ 0.05). Conclusions The skin reactivity to Df and autologous serum plays an important role in the pathogenesis of CU, and the degree of the reactivity to Df and autologous serum is negatively correlated. To conduct ASST and SPT simultaneously in patients with CU may favor the clinical classification and therapy of CU.
