Objective To compare the value of ultrasound and magnetic resonance imaging (MRI) in detecting fetal spine and spinal cord dysplasia Methods Thirty women with complicated pregnancies,age from 22 to 41 years,gestation from 23 - 38 weeks,were studied with MRI within 72 hours after ultrasound studies and revealed 19 cases of fetal spine with irregular,7 cases of vertebral canal widened partly and 4 cases of anomalies of spinal curvature.Autopsy or imaging was conducted when pregnancy was terminated.A close follow-up was given for cases continuing pregnancy within 12 months after delivery.Results (1)Nineteen cases of fetal spine with irregular in ultrasound,the coincidence of antenatal sonographic diagnosis was 42% (8/19),the coincidence of antenatal MRI diagnosis was 89% (17/19).Seven cases of vertebral canal widened partly in ultrasound,the coincidence of antenatal sonographic diagnosis was 0,the coincidence of antenatal MRI diagnosis was 7/7.Four cases of anomalies of spinal curvature in ultrasound,the coincidence of antenatal sonographic diagnosis was 2/4,the coincidence of antenatal MRI diagnosis was 3/4.(2)By MRI study,one cases were conformed their ultrasound diagnosis,eleven cases were completed their ultrasound diagnosis,nine cases were made the same diagnosis as ultrasound and six cases were corrected diagnosis.By MRI and ultrasound study one case of hemivertebra,one case of butterfly vertebra and one case of dorsal dermal sinus were missed diagnosis.Ultrasond had limits and low specificity especially in fetal spinal cord.Conclusions MRI can show the spinal cord and its lesion intuitively and has advantages in displaying fetal anomaly of spine and spinal cord.MRI is a valuable complement to sonography in difficult cases and diagnostic accuracy can be significantly improved.

Objective:To explore the vulnerability and related risk behaviors of the out-of-school adolescents floating with their parents from country to city.Methods:From September to October in 2005,260 out-of-school adolescents who were 14 to 20 years old were investigated in our study.Results:The out-of-school adolescents lacked of HIV/AIDS knowledge and life skills,and their psychosocial competence was at a lower level.The adolescents were open-minded to sex,but they were not conscious of using condoms.Attitude towards people with HIV was positively correlated with a well-being family,harmonious relation between their parents,a stable job,knowledge,life skills and psychosocial competence(such as in control of emotions,empathy).Their life skills were positively correlated with their mothers'schooling satisfaction with family income,a stable job,high scores of knowledge,social responsibility,and interpersonal relationship.Competence of HIV/AIDS prevention was positively correlated with schooling,a stable job,knowledge,life skills,and psychosocial competence.Conclusion:Out-of-school adolescents were vulnerable to HIV/AIDS.Individual level intervention combined with structural intervention could effectively reduce their vulnerability.Effective and feasible health education approach to enhance their life skills and psychosocial competence was a key point to health education on HIV/AIDS prevention.

Objective To study the effects of prenatal exposure to low level lead on the physical and neuro-behavioral development of mice and the interaction between lead and zinc. Methods Kunming pregnant mice were provided with drinking water containing lead, zinc and lead-zinc jointly and respectively. The body weight of maternal mice, offspring's survival rate and body weight were observed. Neuro-behavioral development of offspring was assessed by observation of offspring's behavior performance. The levels of dopamine (DA), 5-hydroxytryptamine (5-HT) and malonaldehyde (MDA) in offspring's brains were measured. Results At the doses of lead and zinc which did not effect the increase of maternal body weight during pregnancy, the lead exposure group showed low survival rate, growth retardation and delay of physiological development and neonatal reflexes in the offspring, the levels of DA and MDA in offspring's brains increased compared with the control group. Offspring's low survival rate and growth retardation couldn't be antagonized by zinc, but equal mole as lead of zinc could inhibit the harmful effects on neuro-reflex development. Zinc could also inhibit the increase of DA and MDA levels in offspring's brains induced by lead . However joint exposure to lead and half dosage as much as lead of zinc could deteriorate the effects on delay of physical, neuro-behavioral development and accelerate the DA and 5-HT decompose compared with that in the lead exposure group. Conclusion The harmful effects on offspring's growth and neuro-behavioral development could be induced by prenatal exposure to low level of lead. The types of joint-effect of lead and zinc were different according to the concentration of zinc, which indicated that the zinc-lead interaction was very complicated and it should be very prudent to antagonize lead toxicity using zinc.

ObjectiveTo investigate the clinical effect of EaLeSu on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with loop electrosurgical excision procedure(LEEP). Methods 165 cases of CIN Ⅱ~Ⅲpatients with HPV infection who underwent LEEP operation were randomly divided into observation group(n=83)and control group(n=82). In the observation group,patients were given a piece of EaLeSu in cervical wound at once in postoperative and two vaginal EaLeSu per day from the first postoperative day for eight consecutive days. The patients in the control group were treated with routine debridement and wound dressing with iodine. We observed the vaginal drainage times within 4 weeks after operative,bleeding rate,cervical wound repair,and cervical HPV DNA infection after 6 months. Results There were significant differences in the bleeding rate,vaginal drainage time,cervical wound repair and HPV DNA infection between the two groups(P < 0.05). Conclusion EaLeSu showed a definite effect on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with LEEP.

Aim To investigate whether hydrogen sul-fide ( H2 S ) inhibits cardiomyocyte apoptosis induced by acute myocardial ischemia in isolated perfused rat heart. Methods The myocardial ischemia injury model was replicated with Langendorff isolated perfused rat heart, and the left anterior descending coronary ar-tery was ligated for 4 h. 40 male SD rats were divided into five groups randomly: sham group, ischemia group, and NaHS groups (5,10,20μmol·L-1). The segmental heart samples were used for HE staining. Cardiomyocyte apoptosis was detected with TUNEL as-say. The expressions of caspase-3 and Cyt-C in hearts were determined with Western blot analysis. Results Myocardial cells were found to show serious disorder and coagulated zonal necrosis under light microscope, the apoptotic rate of cardiomyocytes and the expression of caspase-3 and Cyt-C were significantly increased af-ter ischemia for 4h. Perfusion of NaHS resulted in more clear cell morphology and milder pathologic chan-ges of myocardiocytes according to the HE staining a-nalysis, and the significant decrease of expression of Cyt-C. After perfusion of 10,20 μmol·L-1 NaHS,the apoptotic rate of cardiomyocytes and the expression of caspase-3 were significantly decreased. Conclusion H2 S has certain protective effects on acute myocardial ischemic injury in isolated perfused rat heart via inhibi-ting cardiomyocyte apoptosis.

Objective To approach the protective effect of dexmedetomidine on mechanically ventilated patients with pulmonary contusion. Methods A prospective randomly controlled trial was conducted. 70 mechanically ventilated patients with pulmonary contusion from January 2010 to December 2012 in the Critical Care Medicine of Foshan Hospital of Traditional Chinese Medicine were divided into a control group and a therapy group by the difference in number odd or even,with 35 patients in each group. Based on the same principles of comprehensive treatment,the control group used midazolam,and the therapy group used dexmedetomidine for sedation. The measured parameters included oxygenation index(PaO2/FiO2),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6), and extra-vacular lung water index(EVLWI)for both groups on the1st and 5th day. The incidence of delirium,the time of mechanical ventilation,and the incidence of hypotension were observed in both groups. Results Compared with those on the 1st day,TNF-α,IL-6 and EVLWI on the 5th day were decreased significantly in both groups〔the control group TNF-α(ng/L):1.29±0.38 vs. 2.21±0.37,IL-6(ng/L):97.97±28.77 vs. 131.03±41.52,EVLWI (mL/kg):8.25±2.03 vs. 11.96±3.36;the therapy group TNF-α:1.06±0.33 vs. 2.32±0.37,IL-6:82.07±23.35 vs. 134.98±64.25, EVLWI(mL/kg):6.74±1.33 vs. 11.23±2.78, all P<0.05〕, PaO2/FiO2 was increased obviously〔mmHg(1 mmHg=0.133 kPa),the control group:285.80±30.65 vs. 213.00±33.70,the therapy group:315.00±34.50 vs. 229.50±37.00,both P<0.05〕,TNF-αand IL-6 had no significant difference compared between the therapy group and control group(TNF-α:1.06±0.33 vs. 1.29±0.38,IL-6:82.07±23.35 vs. 97.97±28.77), while EVLWI and PaO2/FiO2 in the therapy group had remarkable differences compared with those of the control group〔EVLWI(mL/kg):6.74±1.33 vs. 8.25±2.03,PaO2/FiO2(mmHg):315.00±34.50 vs. 285.80±30.65,both P<0.05〕. The incidence of delirium(8.57% vs. 22.86%)and time of mechanical ventilation(day:4.10±1.09 vs. 6.88±1.66)in the therapy group were decreased markedly compared with those of the control group,and the incidence of hypotension had no significant difference between treatment or control groups(17.14% vs. 14.29%,P>0.05). Conclusion Dexmedetomidine has protective effect on mechanically ventilated patients with pulmonary contusion, and it is an relatively ideal sedative drug for these patients.

AIM:To investigate whether hydrogen sulfide ( H2 S) protects the hearts against inflammatory re-sponses induced by acute myocardial ischemia in isolated rat hearts .METHODS: Rat acute myocardial ischemia injury was induced by ligation of the left anterior descending coronary artery for 4 h, and the normal perfusate was replaced with NaHS (5 μmol/L, 10μmol/L and 20 μmol/L) perfusate accordingly in NaHS groups 2 h after ischemia.The changes of cardiac function in the myocardial ischemic injury rats were observed .The mRNA expression of TNF-α, IL-1β, IL-6, IL-10 and ICAM-1 was detected by real-time PCR.The protein level of nuclear factor-κB ( NF-κB) in the myocardial tissues was detected by Western blotting .RESULTS:The cardiac function in ischemia group was lower than that in sham group (P<0.01).Compared with ischemia group, perfusion of NaHS resulted in the improvement of the cardiac function (P<0.05 or P<0.01).Compared with sham group, the mRNA expression of TNF-α, IL-1β, IL-6 and ICAM-1 in the cardiac tissues was significantly increased , and the mRNA expression of IL-10 in the cardiac tissues was significantly decreased in ischemia group (P<0.01).Compared with ischemia group , the perfusion of NaHS significantly decreased the mRNA ex-pression of TNF-α, IL-1β, IL-6 and ICAM-1 ( P<0.05 or P<0.01 ) .The perfusion of NaHS at concentrations of 10μmol/L and 20μmol/L significantly increased the mRNA expression of IL-10 (P<0.01).The protein level of NF-κB in ischemia group was markedly higher than that in sham group (P<0.01).Compared with ischemia group, the perfusion of NaHS at concentrations of 10 μmol/L and 20 μmol/L significantly decreased the expression of NF-κB ( P<0.05 or P<0.01).CONCLUSION:H2S protects the hearts against acute ischemia injury through inhibition of NF-κB activation and subsequent down-regulation of NF-κB-dependent inflammatory gene expression .

Objective:To describe the status of subjective well-being among junior high school students in a city of Jiangxi Province and to explore the relationship between family functioning and subjective well-being.To explore the relationship between growth environment and subjective well-being among ju-nior high school students in the perspective of family functioning and to provide basis and data for the mental health education among junior high school students.Methods:630 students in a junior high school in Jiangxi Province were sampled by stratified cluster sampling,and 103 junior high school students from 18 villages were sampled by household survey.They were investigated by subjective well-being scale for adolescents and Family Assessment Device.Results:(1)The overall subjective well-being of junior high school students was in the lower-middle level.Regarding all the dimensions of subjective well-being,they had the highest satisfaction on family and friendship,lowest academic satisfaction,low positive as well as passive emotion.(2)Girls had higher satisfaction on friendship and freedom than that of boys;children from families with more than one kids had more negative emotion than that of single child;boarding students had higher satisfaction on family,academics and freedom than that of non-boarding students;family residence and structure affected the satisfaction on family;grade and learning achievement affected some dimensions of subjective well-being among junior high school students.(3)Pearson correlation analysis and multiple linear regression analysis showed that some dimensions of family functioning were related to certain dimensions of subjective well-being among junior school students,and family functioning could predict the level of subjective well-being.Conclusion:The overall subjective well-being of junior high school students is in the lower-middle level,and further improving is needed.Family functioning has a great influence on junior school students' subjective well-being.Junior high school students who have healthy family functioning are more likely to have higher life satisfaction,and tend to experience higher subjective well-being.

Objective: To investigate the awareness of acquired immune deficiency syndrome (AIDS) knowledge and AIDS-related behaviors among youth students in gay dating sites, and to provide evidences for AIDS prevention education through the internet.Methods: The students in gay dating sites, selected by a snowball sampling, were interviewed by questionnaires.Chi-square tests were used to analyze the awareness of AIDS knowledge among the students of different characteristics.The Logistic regression was used to analyze the factors associated with ever testing for HIV.Results: In the study, 469 youth students in gay dating sites filled in the questionnaires, and a total of 442 (94.2%) valid samples were collected.The awareness of HIV/AIDS knowledge for the public among the youth students in gay dating sites was 83.9% (371).The awareness of HIV/AIDS knowledge for the youth students was 77.1% (341), and the rate of ever testing for HIV was 52.0% (230).The awareness of HIV/AIDS knowledge for the public in the students were different in different age groups (P=0.001), different marital statuses (P<0.001), different sexual orientations (P<0.001), and different genders of the first sexual partner (P<0.001).The awareness of HIV/AIDS knowledge for the youth students were different in different age groups (P=0.010), different marital status (P=0.004), different sexual orientations (P<0.001), and different genders of the first sexual partner (P<0.001).The rate of ever having sexual intercourse among the youth students in gay dating sites was 75.1% (332), and the rate of multiple sexual partnerships among the youth students was 41.3% (137).Compared with homosexual orientation, sexual orientation as heterosexual (OR=0.282,95%CI:0.151 to 0.528) and not sure (OR=0.175,95%CI: 0.035 to 0.885) were risk factors of ever testing for HIV.Multiple sexual partnerships (OR=2.103,95%CI:1.278 to 3.462) were promoting factors of ever testing for HIV.Conclusion: The rate of high-risk behaviors among the youth students in gay dating sites was high.The concern should be raised to heterosexual male students who had tendency to homosexual behavior.The AIDS prevention education should be developed in gay dating sites, to improve the self-protection awareness of the youth students.
