ABSTRACT
Objective@#To understand the relationship between family environment and depressive symptoms among adolescent, and to provide a reference for adolescent mental health promotion and intervention.@*Methods@#From September to December in 2021, a questionnaire survey on family environment and depressive symptoms was conducted among 8 102 middle school students by random cluster sampling method in Shanghai, Urumqi, Changsha and Kunming. The Chi square test was used to compare the depression status of students in different family environments. Multivariate Logistic regression analysis was used to explore the relationship between family environment and depressive symptoms.@*Results@#The detection rates of possible depression, likely depression and severe depression in adolescents were 11.2%, 5.9% and 8.4%, respectively. There were significant differences in the detection rate of depression by gender, academic period, urban and rural areas, family forms and only child statu( χ 2=87.60, 27.19, 6.65, 45.59, 4.78, P <0.05). Logistic regression analysis showed that adolescents in single parent families ( OR =1.45) and reorganized families( OR =1.69) were positively correlated with the occurrence of depressive symptoms compared with those in nuclear families( P <0.01).@*Conclusion@#Compared with nuclear families, the risks of adolescent depressive symptoms in single parent families and reorganized families are higher. Attention should be paid to the mental health education of teenagers from single parents and reorganized families to ensure the development of their physical and mental health.
ABSTRACT
AIM To establish an HPLC method for the simultaneous content determination of four constituents in Shugan Pills (Toosendan Fructus,Corydalis Rhizoma,Paeoniae Radix Alba,etc.).METHODS The analysis of methanol extract of this drug was performed on a 35 ℃ thermostatic C18 column (250 mm ×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-0.05％ phosphoric acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 230 nm.RESULTS Paeoniflorin,naringin,hesperidin and neohesperidin showed good linear relationships within the ranges of 0.040 44-1.011,0.045 20-1.130,0.047 08-1.177 and 0.047 24-1.181 μg (r =0.999 9),whose average recoveries were 100.5％,98.6％,98.4％ and 101.3％ with the RSDs of 1.5％,0.9％,1.2％ and 1.1％,respectively.The contents of various constituents in the samples with three dosage forms from seven manufacturers showed obvious differences.CONCLUSION We should pay attention to the uneven quality of Shugan Pills.
