OBJECTIVETo study the association between rs1079595 polymorphisms in the DRD2 gene and the distractibility in school-age children.

METHODSThe genotyping at rs1079595 was performed and the distractibility was measured based on the temperament questionnaire in 120 8-12 years old school-age children in order to analyze the effects of the rs1079595 polymorphism and its interaction with the gender, age and delivery mode on the distractibility.

RESULTSThere was an association between the distractibility and rs1079595 polymorphisms. The distractibility score in children with GG/GT genotypes was significantly higher than in children with the TT genotype (4.3 ± 0.6 vs 4.0 ± 0.7; P<0.05). The interaction between rs1079595 polymorphisms and the delivery mode produced an effect on the distractibility. The normal delivery children with T alleles were associated with a low distractibility (OR=0.037, P<0.01).

CONCLUSIONSThe distractibility based the temperament might be influenced by the rs1079595 polymorphism and its interaction with the delivery mode in school-age children.

BACKGROUNDCervical cancer is the second most common cause of death from cancer among women worldwide. Human papillomavirus (HPV) plays a central role in the etiology of cervical cancer. It is important to describe the prevalence of HPV infection in different types of cervical lesions and to explore the relation between HPV viral load and the severity of cervical lesions.

METHODSTo describe the HPV infection prevalence and viral load in different age groups, we retrospectively investigated 6405 cases of women who were organized by their units to take health-examination. They were given Hybrid Capture II tests between January 2005 and December 2006. The correlation between HPV viral load and pathology was assessed.

RESULTSOverall HPV infection prevalence was 29.1% (1864/6405), while in women 18-20 years old it was 54.4% (31/57), the highest among all age groups. After declining rapidly, HPV prevalence stabilized at about 30.0% in women aged 30 and older. Of the 6405 women, 1483 women had a colposcopic biopsy and 33.2% (492/1483) were positive for HPV DNA. Twenty-one percent of women with a normal diagnosis (238/1095) had HPV infection, a statistically significantly lower prevalence than in women with cervical lesions, including those with cervical intraepithelial neoplasia (68.8% in CIN1, 66.7% in CIN2, and 76.5% in CIN3) or with cervical cancer (94.1%). The correlation coefficient between viral load and cervical lesion severity was 0.134, which was not statistically significant (P = 0.075). Viral load values in women with CINs and cervical cancer were calculated, and no significant differences were identified.

CONCLUSIONSThe prevalence of high-risk HPV infection among women attending hospitals for health-examination in Shanghai is similar to the worldwide rate. HPV viral load can distinguish cervical lesions from normal individuals but cannot adequately predict the severity of cervical lesions.

Objective　To evaluate significance of squamous cell carcinoma associated antigen (SCC Ag) and carcinoembrynoic antigen (CEA) and carbohydrate antigen 15-3 (CA15-3) in early diagnosis of lung squamous cell carcinoma. Methods　Lung squamous cell carcinoma was induced with methylcholanthrene (MCA) in iodized oil in Wistar rats. Ninty-one rats were used for this experiment, and the rats were sacrificed on the 20th, 40th, 50th, 60th, 70th and 80th days respectively. The stage of the cancer development including atypical hyperplasia, carcinoma in situ, early invasive carcinoma was diagnosed histopathologically. SCC Ag, CEA and CA15-3 in the serum of different conceration stage rats were measured by MEIA technique. Results　Serum levels of SCC Ag, CEA and CA15-3 of the model rats in the atypical hyperplasia and carcinoma in situ had no significant difference. The level of SCC Ag increased predominantly at the early invasive carcinoma(P＜0.01), but the other two markers had no change. Conclusion　SCC Ag level in serum may be of considerable importance in the early diagnosis of lung squamous cell carcinoma.

This study aimed to establish a novel method to screen out the combined components of multi-fractions traditional Chinese medicine (TCM), so that the internal relationship between multi-ingredients could be objectively assessed and the proportioning ratio could be optimized. Taking antiviral effect on neuraminidase activity of influenza virus as the evaluating indicator and using Box-Behnken response surface methodology, the main effective ingredients of Shuanghuanglian injection (SHL) were screened. Meanwhile, the relationship between active ingredients was discussed. Taking SHL as a comparison, the optimum proportioning ratio was predicted. The results indicated that chlorogenic acid, cryptochlorogenic acid, caffeic acid and baicalin have comparatively strong antiviral activity against influenza virus. Moreover, antagonistic action existed between chlorogenic acid and cryptochlorogenic acid, whereas synergistic action between caffeic acid and other components. The optimum proportioning ratio resulted from fitted model is: chlorogenic acid, cryptochlorogenic acid, caffeic acid and baicalin (107 microg x mL(-1) : 279 microg x mL(-1) : 7.99 microg x mL(-1) : 92 microg x mL(-1)). The antiviral activity of the recombined components is stronger than that of SHL, which was consistent with the experiment results (P < 0.05). Box-Behnken response surface methodology has the advantages of general-screening, high-performance and accurate-prediction etc, which is appropriate for screening the combined components of multi-fractions TCM and the optimization of the proportioning ratio. The proposed method can serve as a technological support for the development of modern multi-fractions TCM.
