OBJECTIVE: To explore the association of XRCC3 gene polymorphisms and haplotypes with laryngeal. METHOD: We selected 4 tag SNPs (rs12432907, rs861536, rs861537, rs861531, rs861531) for the present study. 310 laryngeal patients and 310 healthy control subject were genotyping. The distribution of genotypes and haplotypes in these two group was compared. RESULT: The distributions of rs12432907 was significantly different between these two groups. The CCAG haplotype frequency was higher in laryngeal group than that in control group. But TCAG and TTAG haplotype frequency was were lower in the laryngeal patient than that those in the control subject. CONCLUSION XRCC3 gene polymorphism was associated with the risk of laryngeal patients.

Enterovirus type 71(EV71) causes severe hand-foot-and-mouth disease(HFMD) resulting in hundreds of deaths of children every year; However,currently,there is no effective treatment for EV71.In this study,the EV71 poly-protein(EV71-P1 protein) gene was processed and cloned into the eukaryotic expression vector pPIC9k and then expressed in Pichia pastoris strain GS115.The EV71 P1 pretein with a molecular weight of 100 kD was produced and secreted into the medium.The soluble EV71 P1 protein was purified by column chromatography with a recovery efficiency of 70％.The result of the immunological analysis showed that the EV71 P1 protein had excellent immunogenicity and could stimulate the production of EV71-VP1 IgG antibody in injected rabbits.We suggest that EV71-P1 protein is an ideal candidate for an EV71 vaccine to prevent EV71 infection.

0.05).The effective rate of group A was 52.38%(22/42),and group B was 32.35%(11/34).There was significant differences between the 2 groups(P

Objective To investigate the infection and distribution of human papilloma virus (HPV) types in patients with infiltrative cervical cancer (ICC) and cervical intraepithelial neoplasia (CIN) in Chongqing. Methods Fifty-eight cases diagnosed with ICC or CIN[KG-*6]Ⅱ to Ⅲ,which were confirmed by histopathology in the Tumor Hospital of Chongqing,were included in the analysis. DNA enzyme immunoassay (DEIA) and SPF10 LiPA25 (version 1) testing was used for DNA extraction and extension,and linear probe reverse hybridization to detect lesions HPV type. Results HPV infection were detected in 56 of 58 specimen,the positive rates of CINⅡ,CINⅢ and cervical cancer were 100.00%,100.00% and 95.00% respectively. A total of 13 types were detected. HPV16 infection rate was up to 60.00%,followed by HPV18(7.69%),HPV58(7.69%),and HPV31(4.62%). Conclusion HPV16 is still the most common type in Chongqing. HPV18,HPV58 and HPV31 also has a high prevalence.

AIM: To establish a method for determing the dissolution of Breviscapin Dispersive Tablet. METHODS: Breviscapin release was investigated in phosphate BS(pH7.4) by the third method for the release determination (Chinese Pharmacopoeia 2005 edition).Breviscapin content was assayed by HPLC and the release percentage was then calculated. RESULTS: The average recovery of scutellarin was 101.93%,RSD=(1.09)%.Good linear relationship was shown in the concentration range of 0.007-0.18 mg/mL,r=0.999 9.The dissolution was almost unaffected by rotation rate,but greatly affected by the type of solvent. CONCLUSION: The method is sensitive,accurate and quick for the quality control of Breviscapin Dispersive Tablet.

AIM:To research the stability of Compound Wurenchun Soft Capsule in 18 months. METHODS:TLC and HPLC methods were used.Schizandrol A was separated on a ODS-C_(18) column(Lichrospher ODS-C_(18),(4.6 mm?250 mm),) using methyl alcohol-water (65∶35) as the mobile phase,detected at 250 nm.The velocity of flow was 1.0 mL/min.Paeoniflorin was separated on a ODS-C column(Lichrospher ODS-C_(18),4.6 mm?250 mm),using acetonitrile-water-phophoric acid(15∶85) as the mobile phase,detected at 230 nm,the velocity of flow was 1.0 mL/min. RESULTS:There was a good linear relationship at the range of 0.04 mg/mL-0.64 mg/mL for schizandrol A(r=0.999 8).The average recovery of schizandrol A was 98.76%(n=6,RSD=1.18%).There was a good linear relationship at the range of 0.05 mg/mL-0.80 mg/mL for paeoniflorin(r=0.999 9).The average recovery of paeoniflorin was 97.93%(n=5,RSD=1.68%). CONCLUSION:In 18 months,the quality of Compound Wurenchun Soft Capsule is steady.

Objective To investigate the influencing factors of ankylosing spondylitis(AS)patients’life quality and medical coping styles.Method Two hundred patients visiting at the outpatient department of our hospital took part in the assessment on AS life quality and medical coping styles to look into the living quality of AS patients and its medical coping methods and influencing factors.Results The total score on life quality was(66.82±5.57),among whose dimensions the psychological function was scored the lowest by(10.65±4.05). Pearson correlation analysis showed that the scores on confrontation of coping styles were positively related with the dimension of social function in life quality(r=0.18,r=0.13,P<0.05),the scores on the avoidance of coping style were positively related to the dimension of physiological function in the life quality(r=0.12,r=0.14,P<0.05),the scores on yielding in coping styles was negatively correlated to physiological function of the life quality(r=-0.20,P<0.05).Regression analysis results showed that the AS patients’life quality was impacted by the course of the disease,coping styles and modes for paying medical expenses(P<0.05).Conclusions The AS patients’life quality is low and it is related to their coping style,the course of the disease and modes for paying medical expenses.Medical personnel should implement targeted interventions to guide patients into taking correct medical coping styles according to the specific condition of patients,in order to improve their quality of life.
