Objective To study the prevalence of health risk behaviors among the junior high school students.Methods An anonymous questionnaire survey was conducted among a stratified sampling of 1 200 students from six junior high schools to study the health risk behaviors occurred during the last year.Results The leading risk behaviors were lacking sports exercises(47.92%),violating traffic regulation(31.58%),fleeing the home(4.08%),suicide(1.83%),addicted to drugs(0.75%).Conclusion Multiple health risk behaviors exist among junior high school students.We should develop effective measures to prevent these dangerous behaviors and improve students' health.

Objective Taking sham electroacupuncture as control, to observe the clinical efficacy of electroacupuncture in treating female stress urinary incontinence (SUI). Method By using central random design, the eligible subjects were randomized into an electroacupuncture group of 42 cases [electroacupuncture at Zhongliao (BL33) and Huiyang (BL35)] and a sham group of 42 cases [sham electroacupuncture at points beside Zhongliao and Huiyang]. The therapeutic efficacy was evaluated by observing the urine leakage volume in the 1-h pad test and International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Result In the electroacupuncture group, the urine leakage volumes in the 4th, 6th, 20th, and 32nd treatment week were significantly lower than that before treatment (P<0.05);the decreases of urine leakage volume in the electroacupuncture group were more significant than that in the sham group in the 4th, 6th, 20th, and 32nd treatment week (P<0.05). In the electroacupuncture group, the ICIQ-SF scores in the 4th, 6th, 20th, and 32nd treatment week were significantly lower than that before treatment (P<0.05); the ICIQ-SF scores were significantly lower in the electroacupuncture group than in the sham group in the 4th, 6th, 20th, and 32nd treatment week (P<0.05). Conclusion Electroacupuncture can effectively improve urine leakage and other urinary symptoms in SUI.

Objective To explore the effect of blended learning in practical training of acupuncture techniques.Methods Sophomores of acupuncture and Tuinaspeciality were divided into two groups based on classes,with 38 students in experimental group and 34 in control group,adopting blended learning and traditional method in teaching acupuncture techniques respectively.Blended learning mainly adopts mixed methods of both online "punch-card" on WeChat community and offline class learning.Post-test score of two groups were compared by independent samples t-test with SPSS 19.0.The teaching effect of blended learning was evaluated in students in experimental group by questionnaire survey.Results The total score of acupuncture techniques (4.73 ± 0.15) in experimental group were significantly higher than that of control group (4.27 ± 0.46) (t=5.588,P＜0.01) and students' satisfaction concerning the blended learning in experimental group was up to 88％ (22/25).Conclusion Blended learning can promote students' acupuncture skills and cultivate good study habits,making practice in class more targeted.More friendly online learning tools needs to be further developed.
