This study was aimed to investigate the diuretic effect ofMori Cortex and to identify effective fractions inM. Cortex. Metabolic cages were used to firstly observe the diuretic effect ofM. Cortex aqueous extracts on rats. Medications were continuously given for 5 days to screen for the best dosage of diuretic effect. Picric acid assays were used to detect creatinine levels in serum and urine after 5-day medication. Then, the diuretic effect of each chemical split fraction inM. Cortex was studied in order to indentify the effective parts. The results showed that after administration ofM. Cortex aqueous extracts for 3 to 5 days, compared with the control group, there was a significant diuretic effect on rats (P<0.05 orP<0.01). And the medium-dose ofM. Cortex aqueous extracts showed the best effect (P<0.01). However,M. Cortex aqueous extracts had no significant effect on creatinine levels in serum and urine. Assays of diuretic effect of chemical split fractions ofM.Cortex indicated that compared with the control group, 30% ethanol fraction and fatty oil fraction had the best diuretic effect (P<0.01). It was concluded thatM.Cortex aqueous extracts had a significant diuretic effect. And the chemical fractions contributed mostly to this effect were mainly existed in the 30% ethanol fraction and fatty oil fraction.

Objective:To compare acquired immune deficiency syndrome (AIDS) related knowledge, attitudes, behaviors and their influencing factors among college students in different years in Beijing, and to provide evidence for targeted health education among college students in future.Methods: College students were selected by the stratified cluster sampling method, and a questionnaire survey was conducted among college students in year 2006 and 2016 in Beijing.The sample sizes were 1 800 and 3 001 college students, respectively.The contents of the questionnaire included: socio-demographic characteristics, AIDS related knowledge, AIDS related attitude, sex intercourse and its related risk behaviors, condom use intension, and AIDS related health education.Results: Compared with the year 2006, the average AIDS knowledge scores of college students in year 2016 dropped from 12.78±1.95 to 11.90±2.56 (t=12.91, P<0.05), and the correct answer rates of questions in the knowledge part were decreased, too.Except for belief on condom use, the college students were more negative on AIDS related attitude and self-efficacy in year 2016 than in year 2006.Among the students who had sex experience, the rates of commercial sex [17.65% (33/187) vs.6.53% (16/245), χ2=13.003, P<0.001] and the rates of homo-sexual intercourse [15.43% (29/188) vs.4.13% (10/242), χ2=16.356, P<0.001] were higher in year 2016 than in year 2006.The main way for the students seeking pornographic information was changed from books to internet (41.15%) in 2016 compared with the year 2016.In 2016, the influencing factors of intention on condom use were male (OR=0.713), self-efficacy of condom purchase (OR=0.876), never received sex education before college (OR=0.752), self-efficacy of condom use (OR=1.135), belief of condom use (OR=1.775), and attitude towards AIDS patients (OR=1.136).Conclusion: AIDS related knowledge, attitudes and behaviors among college students have been changed, AIDS related health education should be designed and improved based on new characteristics of college students.AIDS health education in colleges should pay more attention to sex attitude and sex responsibility and self-protection awareness among college students as well.

Congenital diaphragmatic hernia (CDH) is caused by unilateral or bilateral diaphragmatic hypoplasia allowing abdominal organs to move into the thoracic,resulting in a series of pathophysiological changes,high mortality and poor prognosis.Therefore,earlier diagnosis is conducive to prenatal intervention and postnatal treatment.At present,prenatal ultrasonography is the most common used examination for CDH due to its convenience and low cost.MRI is complementary to ultrasound examination as it can evaluate both pulmonary development and maturity.Fetal echocardiography is a newly developed method in recent years which helps to indicate the prognosis through observation of hemodynamics and pulmonary vessels development.

Objective : To learn the awareness of chronic diseases prevention and control and its influencing factors among high school students in regions inhabited by ethnic groups,so as to strengthen the prevention of chronic diseases among adolescents in these regions. Methods: Totally 1 050 high school students in Tuquan County,Hinggan League,Inner Mongolia were selected by cluster sampling method. The general information,family factors,attitude to learning,psychological factors,behavioral styles and awareness of chronic diseases prevention and control were investigated,and the influencing factors for the awareness were analyzed by multivariate logistic regression model. Results: There were 1 001 valid questionnaires recovered,with a response rate of 95.33%. There were 685 Han students,accounting for 68.43%,241 Mongol students,accounting for 24.08%,and 75 students with other ethnic minorities,accounting for 7.49%. The average awareness rate of chronic diseases prevention and control was 53.25%;the awareness rates of hypertension prevention measures,smoking and drinking hazards,food susceptible to aflatoxin pollution and high cholesterol food were high,all more than 70%;while the awareness rates of long-term high lipid hazards,high blood pressure diagnosis standard and diabetes symptoms was low,all less than 40%. There was no significant difference in the awareness rate of chronic diseases prevention and control among different nationalities（P>0.05）. The results of multivariate logistic regression analysis showed that the students who were female（OR=1.309,95%CI：1.008-1.700）,had high achievement（OR=1.509,95%CI：1.055-2.159）,and thought exams were important（OR=1.570,95%CI：1.204-2.046）were more likely to have high awareness,while the students who spent five to less than eight hours a day on screens（OR=0.514,95%CI：0.335-0.789）were less likely to have high awareness. Conclusions The awareness rate of chronic diseases prevention and control of high school students in Tuquan County is 53.25%,and there is no significant difference between Mongol and Han students. Gender,academic performance,attitude to examination and time spent on screens can affect the awareness rate.
