Objective To investigate the association between the polymorphisms of apolipoprotein M gene (ApoM) and the risk for cerebral infarction in Han population in northern China.Methods The polymorphisms of ApoM gene were identified by PCR-DNA sequencing analysis and were subsequently detected by PCR-RFLP in 560 patients with cerebral infarction and 550 control subjects in northern China. Statistic analysis was conducted using the SPSS 10.0 program. The linkage disequilibrium (LD) was analyzed by EH and SHEsis softwares. Results Three single nucleotide polymorphisms were found in intron 1 and intron 5 of ApoM gene. The frequencies of GA+AA genotype and A allele of rs805264, GT +TT genotype and T allele of rs707922, CA+AA genotype and A allel of rs707921 were significantly higher in the patients (33.8% and 17.9%, 34.5% and 18.3%, 33.4% and 17.8%, respectively) than in controls (21.1% and 11.2%, 21.8 % and 11.5%, 20.9% and 11.1%, respectively). The LD was found in rs805264, rs707922 and rs707921 of ApoM gene (χ2=2595.03, P<0.01). There was strong LD between each pair of the three markers (D′=0.972 to 0.992). Multiple logistic regression analysis revealed that the A-T-A haplotype of the ApoM gene was an independent risk factor for cerebral infarction (OR=1.780;95%CI=1.333-2.376, P<0.01). Conclusions GA genotype and A allele of rs805264, GT genotype and T allele of rs707922, CA genotype and A allele of rs707921 may be genetic risk factors for cerebral infarction. A-T-A haplotype of ApoM gene may be a susceptible genotype of cerebral infarction.

Objective To explore the ultrasound comparison of PCOS during pre-and pro-cure of laparoscopic ovarian drilling.Methods 14 PCOS cases of the application of pre-and pro-laparoscopic ovarian drilling ovarian were monitored. The changes in the structure,colorful Doppler blood flow characteristics and blood flow parameters changes were observed. Results Significant improvement was observed in post-operative ovarian morphology,ovarian artery blood flow parameters. Conclusion Transvaginal colorful Doppler before and after laparoscopic ovarian drilling has played an indispensable role in monitoring ovarian morphology and blood flow parameters changes on the recovery of ovarian review,evaluating the effect of surgery and the monitoring of ovulation,guiding pregnancy in patients to improve the pregnancy rate.

The pathogenesis of tourette syndrome is not clear yet, and the clinical manifestations are diverse. With modern medi-cal treatment, adverse reactions occur frequently in clinics. Based on syndrome differentiation, TCM treatment can well control the clinical symptoms of children, and achieve better results without obvious adverse reactions. TCM treatment has unique advantages. In the paper, the etiology and pathogenesis, and the classification of the disease were discussed, so as to systematically explore TCM treatment of the disease and provide reference for TCM treatment of the disease.

OBJECTIVETo observe the effects of intervention of moxa smoke with different concentrations on superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and lung of male rats, so as to explore the safety concentration of moxa smoke.

METHODSA total of 32 Wistar male rats were randomly divided into a control group, a low-concentration group, a moderate-concentration group and a high-concentration group, 8 rats in each one. All the rats were exposed in the full-automatic toxicant exposure cabinet, and the overshadow of moxa smoke was set at 0%, 10%, 40% and 70%, respectively. Each rat was exposed for 20 min per day. After 26 weeks, the activities of SOD and content of MDA in serum, lung organ and bronchoalveolar lavage fluid were tested.

RESULTSCompared with the control group, the activities of serum SOD in the high-concentration group were reduced (P< 0. 05), but those in the low-concentration group and moderate-concentration group were not significantly different (both P>0. 05). Compared with the control group, the content of serum MDA in the low-concentration group, moderate-concentration group and high-concentration group was increased insignificantly (all P>0. 05). There were no significant differences regarding activities of SOD and content of MDA in lung organ and bronchoalveolar lavage fluid among each moxa smoke group (all P>0. 05).

CONCLUSIONThere is no obvious toxic reaction in the low-concentration group and moderate-concentration group; in the high-concentration group the antioxidant ability is damaged due to long-term exposure.

OBJECTIVETo understand the willingness to pay for HIV antibody saliva rapid test and its influential factors among people seeking counsel and HIV test, STD clinic patients, university students, migrant people, female sex workers (FSWs), men who have sex with men (MSM) and injecting drug users (IDUs).

METHODSAn anonymous questionnaire survey was conducted among 511 subjects in the 7 groups selected by different sampling methods, and 509 valid questionnaires were collected.

RESULTSThe majority of subjects were males (54.8%) and aged 20-29 years (41.5%). Among the subjects, 60.3% had education level of high school or above, 55.4% were unmarried, 37.3% were unemployed, 73.3% had monthly expenditure <2 000 Yuan RMB, 44.2% had received HIV test, 28.3% knew HIV saliva test, 21.0% were willing to receive HIV saliva test, 2.0% had received HIV saliva test, only 1.0% had bought HIV test kit for self-test, and 84.1% were willing to pay for HIV antibody saliva rapid test. Univariate logistic regression analysis indicated that subject group, age, education level, employment status, monthly expenditure level, HIV test experience and willingness to receive HIV saliva test were correlated statistically with willingness to pay for HIV antibody saliva rapid test. Multivariate logistic regression analysis showed that subject group and monthly expenditure level were statistically correlated with willingness to pay for HIV antibody saliva rapid test.

CONCLUSIONThe willingness to pay for HIV antibody saliva rapid test and acceptable price of HIV antibody saliva rapid test varied in different areas and populations. Different populations may have different willingness to pay for HIV antibody saliva rapid test;the affordability of the test could influence the willingness to pay for the test.
