OBJECTIVE:To provide reference for improving the utilization ratio of emergency contraceptive(EC)pills and re-ducing unwanted pregnancy. METHODS:Among 458 women with unwanted pregnancy in our hospital,self-designed question-naires were used to survey the respondents'knowledge and utilization of EC pills,reasons for not using,sources of EC knowledge and drug availability. The results were analyzed statistically. RESULTS:Totally 458 questionnaires were distributed and then 426 valid questionnaires were collected with effective rate of 93.0%. Among respondents,the awareness rate of EC was 81.2%(346/426),and the rate of those receiving higher education was higher than that of other education levels(P<0.001). 56.3%(240/426) of the respondents had ever used EC pills at one time,the utilization ratio of EC pills were higher in women less than 30-year-old and receiving higher education than other age and educational levels(P<0.01). Only 20.2%(86/426)of the respondents ever used EC pills after the last menstrual period and only 3.5%(3/86) of them took EC pills correctly. Not understanding or knowing EC was the main reason for not using EC pills,accounting for 60.6%(206/340). The highest proportion of source which the respon-dents got EC knowledge was network,accounting for 53.5%(185/346). 37.0%(81/219) of the respondents who had ever pur-chased drugs couldn't purchase EC pills conveniently. CONCLUSIONS:The utilization ratio of EC pills in women with unwanted pregnancy needs to be improved and non-standard drug use is more common. It indicates that health education of contraception still need to be strengthened and the availability of EC pills improved.

Objective To investigate the status of high-risk human papilloma virus(HR-HPV)infection and natural clearance in males whose wife have been infected,and to analysis the coincidence rates of HPV subtypes in couples.Methods Urethra epithelial cells and urethral secretions of 246 males whose wife infected with HR-HPV have been enrolled in the study to detect 13 kinds of HPV subtypes and redetect after 1 year.Results The natural clearance rate of HR-HPV in male was 31.82％(35/110).The infection rate was 44.72％(110/246)in initial detection,while 30.49％(75/246) in redetection,the difference was statistically significant(χ2=10.612,P<0.05).The coincidence rate of HPV subtypes in couples was 15.04％(37/246)in initial detection,while 8.94％(22/246)in redetection,the difference was statistically significant(χ2=4.333,P<0.05).The frequency percentage of HPV16,18 increased significantly in male,the difference was statistically significant(χ2=35.991,P<0.05).Conclusion HR-HPV can be cross-transmitted between infected women and their spouses.It is necessary to detect for her husband once women have been detected high-risk HPV positive.

Objective To study the genetic toxicity of 3 brands of detergents to the root tip cells of Vicia faba in the inducing time and the inducing way(continual mutagenesis,accumulative mutagenesis) with micronucleus and the chromosomal aberration Methods The root tip cells of Vicia faba were taken as the subjects,the genetic safety tests were conducted on those materials treated with detergent of a certain concentration(0.25%) for 2、4、6 h of continual mutagenesis and accumulative mutagenesis respectively.Distilled water was used as the control.Results The continual mutagenesis showed that all the three detergents could induce the root tip cells of Vicia faba to produce micronucleus and chromosomal aberration and as the mutagenic time prolonged,at 6 h,the changes became weak.The genetic toxicity in the accumulative mutagenesis group was greater than that in the continual mutagenesis group.Conclusion According to the results of the present paper,to some extent,detergents may produce genetic toxicity.

BACKGROUND: Anti-virus therapy is not suitable for the patients who have asymptomatic human immunodeficiency virus (HIV); otherwise, it is significant for early intervention of Chinese herbs to cure asymptomatic HIV.OBJECTIVE: To observe the interventional effects of fuzheng paidu pian on level of CD4+T lymphocytes and changes of plasma viral vector expression in early phase of asymptomatic HIV infection.DESIGN : Observational contrast study.SETTING: Institute of Acquired Immunodeficiency Syndrome (AIDS), Henan College of Traditional Chinese Medicine.PARTICIPANTS: A total of 69 asymptomatic HIV patients, who were infected by paid blood, were randomly selected from some countryside in November 2005. There were 39 males and 30 females. Their ages ranged from 30 to 61 years and the mean age was (43±8) years, and the mean course was (13±3) years. Inclusion criteria: ① coincident with diagnostic criteria of asymptomatic HIV infection published by National AIDS committee (modified in 2005); ②from 18 to 65 years old; ③ 200/mm3 ≤CD4+T lymphocyte count ＜ 600/mm3; ④ Patients did not treat with antiviral and other drugs; ⑤ All patients provided the confirmed consent. Exclusion criteria: ① severe liver and renal malfunction,combining with cardio-cerebral vascular disease and severe primary diseases of lung and hematopoietic system,mental diseases; ② primary immunodeficiency, secondary immunodeficiency induced by hormone and radiation therapy, hematologic disease; ③ pregnant or lactational women. Another 25 asymptomatic HIV patients were randomly selected.and regarded as the blank group. Inclusion and exclusion criteria were as the same as those in the treatment group.METHODS: Patients in the treatment group were treated with fuzheng paidu pian (consisting of huangqi, raw baizhu,fangfeng, baihuashe shecao, ganca o, etc.; Aolinte Pharmaceutical Factory of Henan Institute of Traditional Chinese Medicine; batch number: 050601) by using warm boiled water, 5 tablets once (eqUal to 6.6 g raw materials) for three times a day. Three months were regarded as a course and the treatment was performed four courses in total. Patients in the blank group were not treated with any drugs.MAIN OUTCOME MEASURES: ① Values of CD4+, CD8+ and CD4+/CD8+ in the treatment group before and after treatment;CD4+T lymphocyte count in the blank group after 6 months; ② Viral vector was detected by using reverse transcription polymerase chain reaction (RT-PCT) in the treatment group.RESULTS: All 69 patients in the treatment group and 25 patients in the blank group were involved in the final analysis. ①CD4+ value was decreased in the blank group after 6 months, and there was significant difference before and after 6 months based on α =0.05 level (P ＜ 0.05).However, CD4+ value was increased in the treatment group. ② Viral vector was randomly detected from 23 patients in the treatment group. As compared with before treatment, plasma viral vector was decreased in 9 patients at 6 months after treatment and in 12 patients at 1 year after treatment. The effective rate was 91.30%.CONCLUSION: Fuzheng paidu pian can improve immunological function of asymptomatic HIV patients and decrease viral vector in some cases during early interventional period.

Objective To determine whether morphine postconditioning (MP) could protect the heart against ischemia reperfusion (I/R) injury and which specific type(s) of the opioid receptor is involved in the cardioprotective effect produced by hiP. Methods Male SD rots weighing 180-200 g were killed after intraperitoneal heparin 500 U/kg. The hearts were immediately removed and passively perfused in a Langendorff apparatus with K-H solution gassed with 95% O2-5% CO2. HR and left ventricular systolic pressure (LVSP) were measured from a fluid-filled latex balloon in the left ventricle. Global myocardial ischemia was induced by interrupting perfusion for 45 min followed by 60 min reperfusion. The experiment was performed in 3 parts. In Part Ⅰ 32 isolated rat hearts were randomly divided into 4 groups (n = 8 each): group Ⅰ control received no treatment; group Ⅱ ,Ⅲ,Ⅳ were first perfused with K-H solution containing morphine 0.3, 3.0 and 30 μmol/L respectively for 10 min immediately after the end of ischemia followed by 50 min normal K-H solution perfusion. In part Ⅱ,the concentration of morphine in K-H solution which provided the best cardio-protective effects was chosen according to the result of Part Ⅰ , 32 isolated rat hearts were randomly divided into 4 groups ( n = 8 each) : group Ⅰ received no treatment; gvoup Ⅱ,ⅢⅣ were first perfused with K-H solution containing morphine for 5, 10, 20 min respectively immediately after ischemia followed by 50 min peffusion with normal K-H solution. In part Ⅲ,the MP method which provided the best cardio-protective effects was chosen according to the result of Part Ⅱ , 37 isolated rat hearts were randomly divided into 5 groups: group Ⅰ control (n=8);group Ⅱ-Ⅴ were first perfused for 10 min with K-H solution containing morphine (Ⅱ,n = 8)/morphine + naloxone 10 μmol/L(Ⅲ, n = 7)/morphine + nor-binaltorphimine 5 μmol/L (specific κ receptor antagonist, n = 7)/morphine + nalu'indole 5 μmol/L (specific δ receptor antagonist, n = 7) followed by 50 min reperfusion with normal K-H solution. Myocardial CK-MB activity was measured and myocardial infarct size (IS/AAR) determined (by 2,3,5-triphenyl tetrazolium staining) at the end of 60 min reperfusion.Results The postconditioning with morphine 3.0 μmol/L perfusion for 10 min provided the best cardio-protective effects in terms of IS/AAR and myocardial release of CK-MB. Nuloxone completely abolished the cardio-protective effects of MP. Nor-binaltorphimine partly reversed the protective effect of MP, while naltrindole had no effects on MP. Conclusion MP protects the heart against I/R injury via activating κ receptor.

Objective:To develop and evaluate the Cancer Dangerous Factor and Aura Manifestation List(CDFAML).Methods:A self-report questionnaire was developed.A total of 639 cancer patients were asked to complete the questionnaire and evaluate the importance of each item.And 129 relatives and 103 doctors and nurses were also asked to evaluate the importance of each item.706 healthy people whose demographics were similar to the patients were asked to complete the list.Results:①CDFAML was finally refined as a list with 19-item;the 4 dimensions including somatic,psychological,social factor and life habits.②The list had good construct validity and could well reflect the dangerous factor and aura manifestation of the onset of cancer.The 4 dimensions and the total score of the patients were significantly different from healthy people's scores.③ The test-retest coefficients for the 4 dimensions and the total score were 0.82,0.76,0.80,0.77 and 0.83 respectively;Cronbach ? was 0.76,0.79,0.83,0.80 and 0.86 respectively.The split-half reliability of the questionnaire was 0.90.Conclusion:CDFAML has high validity,reliability.

AIM: To investigated the changes of hippocampus noradrenaline levels and its tyrosine hydroxyase (TH) , monoamine oxidase A (MAOA) expressions during chronic psycological stress procedure and physical exercise in rats. METHODS: Male Wistar rats (n =24) were randomly assigned to three conditions; (1) restraint stress (S) at 6 h/d for 3 weeks; (2) 24 h access to activity wheel running (E) for 4 weeks; (3) a sedentary control group (C). Levels of NE were assayed by high performance liquid chromatography with electrochemical detection. Protein expression of TH and MAOA were detected by Western blotting. RESULTS: Compared to C, weight loss and sucrose consumption rate decrease were induced in S, and NE was lower while TH and MAOA expressions increased significantly. In E group, NE was higher and TH, MAOA increased distinctly. CONCLUSION: It is suggested that hippocampus NE level may play an important role in the mechanism on the protection of physical exercise to chronic psycological stress, there is no close connection between NE change and TH, MAOA.Other mechanisms may exist.
