Objective To summarize the experience of HIV/AIDS preventive interventions among out-of-school teenagers and provide scientific evidence for the development of large-scale interventions in the future. Method Using both non-random snowball and cluster sampling approach,a total of 5,000 participants were selected from 7 provinces (9 provincial sites ) and a cross-sectional survey was conducted by employing a semi-open-ended self-administrative interview schedule to evaluate their behavioral change before and after the interventions. Results The rate of HIV related knowledge and condom use increased significantly among the participants. For instance,the rate of condom use when having sex at the last time increased by 34.86%,i.e. from 27.67% at the baseline to 59.88% after the intervention (?2=34,86,P

Objective To understand the dietary intake of pregnant women, and try to give a reasonable sug-gestion to promote fetal development. Methods 400 pregnant women in Fushan city were enrolled in this study and their dietary intake were investigated, then the software of Analysis of pregnancy nutrition guidance system was used to make nutrition analysis. Results The ratio of the energy in each pregnancy provided by dietary protein, carbohy-drate and fat were relatively appropriate. But the intake of dietary calcium, ferrum, zinc, vitamin B1 and vitamin B2 in early pregnancy were very low, the intake were respectively 764.51 mg, 26.94 mg, 15.71 mg, 1.12 g, 1.13 g. Each pregnancy the ratio of high-quallty protein in total protein intake were more than 50%, an average protein RNI% was 48.50%. Conclusion The dietary style of pregnant women is relatively reasonable. But they should strengthened nutritional guide to intake more calciuro,ferrum, zinc,vitamin B1 and vitamin B2.

Objective To explore the effect of depakine in the treatment of traumatic epilepsy relapse,and compared carbamazepine and lamotrigine combined with depakine in the treatment of traumatic epilepsy.Methods Open trial in 131 patients with traumatic epilepsy relapse treated with depakine,and all patients were aderministered with carbamazepine or lamotrigine combined with depakine.3 months before treatment,the epilepsy seizures frequency was compared,and 6 months after the treatment,the efficacy,adverse reactions and safety was compared between two mothods.Results Application of carbamazepine or lamotrigine combined with depakine treatment for 6 months,the seizure frequency significantly decreased compared with before treatment;The seizure frequency reduction( ≥50％ ) were 72.6％ and 91.3％,the difference was statistically significant between before and after treatment( P ＜ 0.01 ) ;The adverse reactions of carbamazepine combined with depakine was 37.1％,and it of lamotrigine combined with depakine was 8.7％.Conclusion Lamotrigine combined with depakine in the treatment of traumatic epilepsy recurrence was effective,and its side effects was light.

ObjectiveTo investigate the causes of groin lymphatic fistula after transluminal ultrason ic angioplasty (TUA) in the treatment of deep vein thrombosis(DVT) of lower extremity through groin incision. Methods A retrospective anal ysis of the causes of groin lymphatic fistula(GLF) in 72 patients with DVT after treatment of ultrasonic ablation was made. ResultsTUA and thr ombectomy using Forgaty balloon catheter for DVT of lower extremity achieved successful recanalization in all the 72 cases (100%). Of the 72 cases,51 had i liac vein stenosis,the venous stenosis disappeared after balloon dilation;amo ng the 51 cases ,6 cases received stent placement. GLF occurred postoperati vely in 60 cases. No death occurred in this series. ConclusionsTUA is an effective method in the treatment of DVT of lower extremity,but t he incidence of postoperative GLF is high.The causes of GLF may be related to the injury of lymphatic vessels, increase of quantity of lymph flow induced by increased venous pressure, infection, surgical technique factors and postop erative medicine therapy etc.

By applying the satellite-based distance rescue system and telemedical technology to the emergency treatment of the wounded from the Wenchuan Earthquake,we successfully conducted joint telemedical consultations with the guidance of the top specialists from various distant areas and saved 3 critically wounded patients.Our experience has shown that telemedical consultations may give a full play to the functions of large rescue organizations and the abilities of the top specialists,improve the treatment and expand war-time medical support.
