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 investigate the effect of lower limb rehabilitation training robot combined with task-oriented training on walking ability after stroke. Methods From February 2014 to August 2015,74 consecutive patients with post-stroke who received rehabilitation therapy and met the inclusion criteria admitted to the Department of Rehabilitation Medicine,Xuanwu Hospital,Capital Medical University were collected prospectively. They were all the patients with the first-ever stroke for 1 to 12 months. They were divided into either an observation group (n = 39)or a control group (n = 35)according to whether they were treated with the lower-limb rehabilitation robot. The patients of both groups received task-oriented training,2 times a day,once for 20 min,5 days a week for 12 weeks. The observation group was also treated with the lower-limb rehabilitation training robot,1 time a day,once for 30 min,5 days a week. Berg balance scale,Fugl-Meyer assessment (FMA),timed up-and-go test (TUG)and knee flexion active range of motion (KFAROM)were used to assess the efficacy. Results (1)After treatment,the Berg scale and FMA scale scores were increased in the observation group and the control group compared with before treatment. There was significant difference (Berg scale:28 ±9 vs. 22 ±9,29 ±9 vs. 24 ±9;FMA scores:47 ± 8 vs. 36 ± 8,40 ± 6 vs. 36 ± 7;all P < 0. 01),however,there was no significant difference between the two groups (P <0. 05),and there was significant difference in FMA scores between the 2 groups (P < 0. 01 ). The differences of Berg scale scores in the observation group and the control group were 10. 75 + 0. 30 and 4. 71 + 0. 14 respectively before and after treatment. There was no significant difference between the 2 groups (t = 0. 95,P = 0. 345). The differences of FMA scores in the observation group and the control group were 5. 8 ±0. 6 and 4. 9 ±0. 8 before and after treatment (t =5. 16,P <0. 01). (2)After treatment,the tug test and KFAROM of the observation group and the control group were better than those before treatment. There were significant differences (TUG test:35 ± 13 s vs. 56 ± 18 s,53 ± 17 s vs. 58 ± 18 s;KFAROM:82 ± 24° vs. 60 ± 23°,63 ± 23° vs. 57 ± 26°;all P < 0. 01),and there were significant differences between the 2 groups (all P < 0. 01). The differences of the TUG test in the observation group and the control group before and after treatment were 21. 5 ± 5. 0 and 4. 6 ± 0. 6 s respectively. There was significant difference between the 2 groups (t = 9. 55,P < 0. 01);the differences of KFAROM in the observation group and control group before and after treatment were 5.8 ±0.6° vs. 4.9 ±0.8° respectively. There was significant differences between the 2groups (t =4.17,P <0. .01). Conclusion Lower limb rehabilitation training robot combined with task-oriented training may improve the lower extremity motor function,walking ability,knee flexion joint activity of the patients after stroke,but the improvement effect of the lower limb balance is not obvious.

Objective To examine the distribution of Malassezia species in follicular contents and perifollicular superficial skin in patients with Malassezia folliculitis and search for its causative agent. Methods A total of 120 patients with Malassezia folliculitis were investigated. Follicular lesions at three different anatomic sites were selected in each patient. Perifolliclar superficial skin specimens were taken by sterile adhesive tape, and the follicular contents of the same follicle were taken by sterile haemostatic forceps. The above specimens were cultured respectively on media containing rapeseed oil. The isolated colonies were identified by their physiological and morphological characteristics. Results Out of 319 isolates obtained from the perifollicular superficial skin, 247 isolates (77.43%) were identified as M. sympodialis, 40 isolates (12.54%) as M. furfur, 27 isolates(8.46%) as M. globosa and 5 isolates(1.57%) as M. obtusa. Out of 314 isolates obtained from follicular contents, 252 isdates(80.25%) were identified as M. globosa, 57 isolates(18.15%) as M. sympodialis, 4 isolates(1.27%) as M. furfur, and 1 isolate(0.32%) as M. obtusa. There was statistical difference in species distribution between the follicular contents and the perifolliclar superficial skin (P

Objectives To compare the difference between multipoint inoculation and routine method for isolation of pathogenic fungi from nail samples of onychomycosis,and to analyze the epidemiology of pathogenic fungi in those patients.Methods The nail clipping samples from each patient were inoculated onto the plates with Sabouraud's agar,Sabouraud's agar without cycloheximide and medium containing rapeseed oil,respectively,by an approach of at least seven inoculating points in each plate (multipoint inoculation),and onto medium slope in tubes with the same media as above mentioned (routine method).In the multipoint inoculation method,plates with more than 3 colonies were taken for further identification of pathogenic fungi based on morphological and biochemical properties.Results Based on the data from 150 samples of onychomycosis,significant differences were found between multipoint inoculation method and routine method (P

Objective To investigate the expression and clinical significance of leptin receptor (OBR) and phosphorylation of signal transducer and activator of transcription (p-STAT3) in patients with diffuse large B-cell lymphoma (DLBCL).Methods Immunohistochemical analysis was used to detect the expression of OBR and p-STAT3 in 80 patients with DLBCL and 10 patients with reactive lymphoid hyperplasia (RLH).Using a panel of immunohistochemical markers (CD10,bcl-6 and Mum-1),all cases of DLBCL were further divided into two groups,GCB (germinal center B-cell-like) or non-GCB.Results Immunohistochemistry revealed high expression of OBR and p-STAT3 in 45.0 ％ (36/80) and 28.8 ％ (23/80) cases of DLBCL,respectively,and minimal straining in 100.0 ％ (10/10) cases of RLH (P ＜ 0.05).Compared with GCB group (8.7 ％,2/23),non-GCB group had higher p-STAT3 high expression rate (36.8 ％,21/57) (P ＜ 0.05).There was no significant difference in the expression of OBR between these two groups.Compared with clinical stage Ⅰ-Ⅱ [46.2 ％ (18/39) and 25.6 ％ (10/39)],stage Ⅲ-Ⅳ had higher OBR and p-STAT3 high expression rate [61.9 ％ (13/21) and 38.1％ (8/21)] (P ＞ 0.05).The expression of OBR and p-STAT3 were not correlated with age,gender,extranodal infiltrations,LDH level,B-symptoms and IPI(international prognostic index)(P ＞ 0.05).The expression of OBR was positively related with that of p-STAT3 in DLBCL patients (r =0.232,P =0.039).Conclusion OBR could stimulate the JAK-STAT signaling pathway and induces the phosphorylation of STAT3.This may be involved in carcinogenesis and prognosis of DLBCL.
