Objective The health risk behaviors of undergraduates exist universally, which can induce other social problems. The aim of this study was to describe the present situation and analyze the influencing factors of health risk behaviors of 404 undergradu-ates. Methods Adolescent Health Related Behaviors Questionnaires were conducted in 404 undergraduates chosen from a University in Nantong by stratified cluster sampling method.Logistic regression and multiplicative interactive effects were adopted to analyze the influ-encing factors. Results Health risk behaviors were common among college students.In the past 30 days, 33.4%of students had rule-breaking behaviors in bicycle riding and 45.3%had rule breaking behaviors in walking.In the past 12 months, 2.7%of students had in-tentionally hurt themselves, 2.5%had suicidal inclination, 19.8%had smoking history, 69.3%had drinking history, 7.4%participa-ted in the gambling, 7.7%and 11.9%played video games and surfed online over 4 hours everyday, respectively, and 4.5%of students have had sex.In the past 30 days, 94.3% of students lost their weight through the unhealthy way, and 37.8%of students participated physi-cal exercise over 60 minutes for at least 3 days in the past 7 days.Lo-gistic regression indicated that male, higher grade and higher education level of the student′s mother were the risk factors of some health risk behaviors.Interactive effect was not found between the different influencing factors. Conclusion Health risk behaviors exist widely a-mong college students and more attention should be paid to risk behaviors of college students.Health behaviors should be trained among adolescents to improve their overall health level.

ObjectiveTo investigate the effects of care bundles on the lactation of mothers of preterm infants.MethodsFrom January to June 2015, postpartum women who had preterm deliveries in First Maternity and Infant Hospital Affiliated to Tongji University with the neonates hospitalized in neonatal intensive care unit were enrolled in this study. They were randomly divided into intervention group (n=25) receiving bundle care (assist the mothers to determine lactation target; pump/express breastmilk within six hours after birth and keep a lactation diary to record the times and volume of pumped/expressed milk) and control group (n=22) given normal mammary guidance only. The time of the first pumped/expressed milk, the times for pumping/expressing milk a day, the total milk volume per day and rate of breastfeeding were compared between the two groups. Statistical analyses were conducted using two independent samplest-test,Chi-square test and nonparametric test.ResultsThe initial time of pumped/expressed milk of the intervention group was (6.1±3.4) h after delivery, significantly earlier than the control group [(10.7±9.3) h](t=-2.301,P=0.026). The times for pumping/expressing milk per day were significantly more in the intervention group than in the controlgroup on the 1st, 2nd and 3rd day after delivery [(4.2±2.2) vs (3.0±1.6); (6.2±1.1) vs (4.7±1.9); and (7.1±1.9) vs (5.9±1.9) times, respectively](t=2.083, 2.564 and 2.194, allP<0.05). From the second postpartum day, the milk volume of the intervention group was more than the control group [M(range) were 10.0(25.0) vs 2.0(5.0) ml] (Z=-2.879,P=0.005); and on the 21st day, the milk volume of the intervention mothers reached 800.0(295.0) ml, still higher than the control group [300.0(155.0) ml](Z=-3.179,P=0.001). The primarily breastfeeding (adding formula milk≤2 times a day) rate in the intervention group was significantly higher than in the control group on the 42nd postpartum day [68% (17/25) vs 41% (9/22),χ2=5.874,P=0.045].ConclusionThe care bundles on lactation can improve the lactation of the mothers of preterm infants.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.
