BACKGROUND: The population of male and female adolescents in China accounts for 1/5. Adolescents have much psychological bewilderment,troublesome and even diseases on sexual issues.OBJECTIVE: To investigate the development status quo and the regulation of adolescents' sexual physiology, sexual psychology, sexual knowledge and sexual education.DESIGN: A cross-sectional survey by employing students of junior high school as subjects.SETTING: A clinic for adolescent of a tertiary hospital.PARTICIPANTS: Totally 960 students aged between 14 and 19 years old of three junior high schools in Dalian city were selected as subjects between November and December of 2001.METHODS: Self-complied questionnaire was used in the survey based on the sexual psychological education situation scale for junior and senior high school students. Classes were randomly selected for anonymous survey based on voluntary principle.Answers to sex-related questions and differences between male and female students.RESULTS: The average age of menarche in female students was 12.96years old and the average age of first emission in male students was 13.89years old, which were consistent with the results of similar national researches. The incidence and frequency of masturbation and sexual impulse was significantly higher in males than females. There were significant differences in sexual concept and the understanding of sexual knowledge between males and females. The desire to affiliate with the opposite sex was far more than the real occurrence.CONCLUSION: The understanding of sexual knowledge in adolescent is not satisfied. Students are also not satisfied with the sexual education provided by their schools. Hence, school sexual education for adolescents should be enhanced with the involvement of community.

Objective To evalute the effects of subcutaneous transfection of human beta-nerve growth factor (Ad-hNGFβ) gene on the function of sensory nerve in a rat model of diabetic neuropathic pain (DNP).Methods Healthy male Sprague-Dawley rats,weighing 180-220 g,were used in this study.Ten rats were randomly collected as normal control without DNP (group C).DNP model was established by intraperitoneal injection of streptozocin (STZ) 75 mg/kg.Seventy-five rats with DNP were randomly divided into 3 groups (n =25 each):DNP group; Ad-hNGF group and Ad-LacZ group.Groups Ad-NGF and Ad-LacZ received subcutaneous transfection of 1.12 × 1011 PFU Ad-hNGFβ 10 ul and 1.12 × 1011 PFU Ad-LacZ 10 ul respectively after pain thresholds were measured on 21 days after STZ injection.The mechanical and thermal pain thresholds were measured before STZ injection (baseline) and at 21,35 and 49 days after STZ injection.The conduction velocity and latency of the sensory nerve and the expression of substance P (SP) in dorsal root ganglion (by immmuno-histpchemistry) were determined after measurement of pain threshold on 49 days after STZ injection.Results Compared with group C,the mechanical and thermal pain thresholds were significantly increased at each time point after STZ injection in groups DNP,Ad-NGF and Ad-Lacz,the conduction velocity of the sensory nerve was significantly decreased,the latency of the sensory nerve was prolonged,and the expression of SP in dorsal root ganglion was down-regulated in groups DNP and Ad-LacZ,the conduction velocity of the sensory nerve was significantly decreased (P ＜ 0.05),and no significant change was found in the latency of the sensory nerve and expression of SP in dorsal root ganglion in group Ad-NGF (P ＞ 0.05).Compared with group DNP,the thermal pain threshold was significantly increased at 49 days after STZ injection,the conduction velocity of the sensory nerve was decreased,the latency of the sensory nerve was shortened,and the expression of SP in dorsal root ganglion was down-regulated (P ＜ 0.05 or 0.01),while no significant change was found in the mechanical pain threshold in group Ad-NGF,and no significant change was found in the parameters mentioned above in group Ad-LacZ (P ＞ 0.05).Conclusion Subcutaneous transfection of Ad-hNGFβ can improve the function of sensory nerve in a rat model of DNP through up-regulat-ing of the SP expression in dorsal root ganglion.

Objective:To analyze and summarize the commonalities and patterns in acupoint selection for moxibustion treatment of asthma. Methods: Data retrieval was conducted using ‘moxibustion’ and ‘asthma’ as the keywords through China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP). Excel 2010 was used to establish the major acupoint database for moxibustion prescriptions in treatment of asthma; data mining methods including association patterns and clustering were adopted to analyze the characteristics and patterns in acupoint selection for moxibustion treatment of asthma. Results: A total of 161 moxibustion prescriptions were recruited. The most commonly used acupoint was Feishu (BL 13), the most commonly used meridian was the Bladder Meridian of Foot Taiyang, and the most commonly treated region was the back. The association rule analysis showed that Feishu (BL 13)-Dazhui (GV 14)-Fengmen (BL 12) had the most significant correlation, and the clustering analysis discovered 5 effective acupoint clusters. Conclusion: In moxibustion treatment of asthma, topical acupoints Feishu (BL 13), Dazhui (GV 14) and Fengmen (BL 12) can be selected, along with the acupoints from the Bladder Meridian of Foot Taiyang and the back.

Objective To observe the therapeutic effect of rhubarb combined with Probiotics for treatment of patients with severe acute pancreatitis (SAP) accompanied by acute lung injury (ALI). Methods A prospective randomized controlled trial was conducted. Sixty patients with SAP and ALI were randomly divided into a rhubarb group and a combination of rhubarb and Probiotics group (combined group), 30 cases in each group. Both groups were treated with conventional therapy. On that therapeutic base, the patients in rhubarb group were treated with rhubarb 3 g·kg-1·d-1 (Raw rhubarb in boiling water 200 mL was cooked for 30 minutes, then the decoction was divided into two parts to be infused through nasal jejunal tube, retaining for 1 hour);while in the combined group, beside the above rhubarb therapy, the patients were additionally given Probiotics [Clostridium butyric acid:Chang Lekang capsule, once 1 grain (0.42 g), twice a day] through nasal jejunal tube. The therapeutic course was 14 days in the two groups. The plasma endotoxin levels, oxygenation index, and acute physiology and chronic health evaluationⅡ(APACHEⅡ) score were observed before and after treatment for 7 days and 14 days, respectively. After treatment for 30 days, the time of intestine functional recovery and mechanical ventilation, number of damaged organs, number of infectious sites, number of pancreatic pseudocysts, length of intensive care unit (ICU) stay and 30-day fatality rate were observed in the two groups. Results With the prolongation of treatment, the plasma level of endotoxin and APACHEⅡscore in the two groups were gradually reduced, and the oxygenation index was gradually increased after treatment for 7 days and 14 days in the two groups compared with those before treatment, and there were statistically significant differences in above indexes on the 14th day after treatment between combined group and rhubarb group [endotoxin (μg/L): 19.16±1.90 vs. 21.20±1.05, oxygenation index (mmHg, 1 mmHg = 0.133 kPa): 369.50±5.45 vs. 341.50±7.36, APACHE Ⅱscore:11.84±0.60 vs. 13.00±0.86, P<0.05 or P<0.01]. The length of intestine functional recovery in the combined group was longer than that in the rhubarb group (days: 5.63±1.75 vs. 5.02±1.54), the number of damaged organs (2.08±0.74 vs. 2.70±1.11), the number of infectious sites (1.93±0.64 vs. 2.23±0.83), the number of pancreatic pseudocysts (1.22±0.34 vs. 1.63±0.11) and the mortality rate [10.0%(3/30) vs. 13.3%(4/30)] in the combined group were lower than those of the rhubarb group, but there were no statistically significant differences between two groups (all P > 0.05). The times of mechanical ventilation (days: 13.40±1.76 vs. 15.60±1.28) and the length of ICU stay (days:16.13±1.25 vs. 17.63±1.30) were significantly shorter in combined group than those in rhubarb group (both P<0.05). Conclusion Rhubarb combined with Probiotics for treatment of patients with SAP and ALI can promote their recovery of lung function and shorten their length of ICU stay.

Objective To investigate the correlation between carotid artery plaque and blood pressure variability (BPV) in elderly patients with hypertension.Methods One hundred sixty elderly patients with hypertension were divided into plaque and non-plaque groups according to the results of carotid artery ultrasonography.All the patients were measured by ambulatory blood pressure monitoring.The mean blood pressure,mean pulse pressure,and blood pressure variability coefficient of two groups were calculated and compared during whole day,daytime,and nighttime.The related factors of carotid artery plaque were analyzed by multivarite logistic regression analysis.Results The 24 h systolic blood pressure standard deviation,daytime and nighttime of systolic blood pressure standard deviation,daytime diastolic blood pressure standard deviation of plaque group were higher than those of non-plaque group (P ＜ 0.05).The 24 h systolic blood pressure variation (24 h SBPV) and night systolic blood pressure variation (nSBPV) were higher than those of non-plaque group (P ＜0.01).Multivariate regression analysis results showed that carotic artery plaque was associated positively with 24 h BPV and blood pressure variability coefficient of nighttime (P ＜ 0.05).Conclusions The elderly hypertensive patients with carotid artery plaque is associated positively with 24 h systolic blood pressure variability coefficient and blood pressure variability of nighttime.
