RESUMO
Objective@#To explore the relationship between adolescents physical fitness and depressive symptoms, and to provide reference for the early prevention and intervention of depressive symptoms and improvement of physical fitness in Chinese adolescents.@*Methods@#From September to December 2021, a total of 8 102 adolescents were selected by random cluster sampling method in Shanghai, Urumqi, Changsha and Kunming. The Center for Epidemiologic Studies Depression Scale(CES-D) was used to investigate the depressive symptoms, and completed grip strength, standing long jump, 50 m running, modified sitting forward flexion, 20 s repeated traverse, 30 s sit ups, 20 m round trip running (20 m SRT) test. χ 2 test, Goodman Kruskal Gamma and Logistic regression analysis were used to analyze the relationship between physical fitness index(PFI) and depressive symptoms.@*Results@#The overall detection rate of depressive symptoms in adolescents with high level PFI was 23.4%, and the detection rate of low level adolescents was 26.3%, with a statistically significant difference ( χ 2=6.73, P =0.01). There was a significant positive correlation between PFI and depressive symptoms in the high school group ( G=0.09, P <0.05) and the boy group ( G=0.12, P < 0.05 ), and there was no significant association between PFI and depressive symptoms in the junior high school group and the girl group ( P >0.05). After adjusting for gender and age in the Logistic regression model, compared with those with high PFI, the risk of depressive symptoms in those with low PFI was 1.18 times (95% CI =1.05-1.33).@*Conclusion@#There is a correlation between physical fitness and depressive symptoms in adolescents. Adolescents with low PFI are at higher risk of developing depressive symptoms than those with high PFI.
RESUMO
Objective@#To explore the correlation between different nutritional status and depressive symptoms among adolescents, so as to provide a theoretical basis for targeted improvement of nutritional status and depressive symptoms in adolescents.@*Methods@#A total of 8 102 adolescents aged 12-17 years in Shanghai, Urumqi, Changsha and Kunming were selected by random cluster sampling. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale(CES-D). Height and weight were measured. Kruskal Wallis H test, Chi square test and ordinal Logistic regression were used to analyze the relationship between nutritional status and depressive symptoms in adolescents.@*Results@#The overall detection rate of depressive symptoms in adolescents was 25.6%, with girls (30.1%) higher than that of boys (21.1%) ( χ 2=87.60, P <0.01). There were statistically significant differences in the scores of depressive symptoms among girls with different nutritional status ( Z =8.34, P <0.05). The detectable rate of depressive symptoms increased with BMI among girls( χ 2 trend =6.04, P <0.05). After controlling for confounding factors, ordinal Logistic regression showed that the obese girls had higher risks in depressive symptoms detection compared with normal weight girls ( OR=1.45, 95%CI=1.10-1.91, P <0.05).@*Conclusion@#The nutritional status of girls is better than boys, but the prevalence of depressive symptoms is higher than boys. The risk of depressive symptoms in girls increases with BMI.
RESUMO
OBJECTIVE To detect the trace glutaraldehyde in the fluid from venous circuit tube of hemodialysis,a HPLC assay was developed.METHODS 20 mL fluid taken from the venous circuit tube were derived with DNPH for 3 h,then filtered and injected. Chromatography was conducted on C18 column at 29℃.The mobile phase was consisted of 60% CH3N and 40% H3PO4 with the flow rate at 1 mL*min-1, and the detetion wavelength was at 365 nm.RESULTS The concentrations of glutaraldehyde in the fluid ranged from 14.99 to 37.40 μg.mL-1.CONCLUSION This HPLC method is simple and accurate to detect the trace glutaraldehyde remained in the fluid from venous circuit tube.
RESUMO
Objective To study the effect and adverse drug reaction (ADR) of Diazepam when used to treat acute alcoholism for establishing its rational use. Methods According to the administration of the drug through different routes, 158 patients admitted from Jan. 2000 to Jan. 2006 were divided into two groups- intramuscular group (i.m., n=91) and intravenous group (i.v., n=67). There was no significant difference in age, sex, amount of liquor taken, time of seeing doctor, and drug dosage between the two groups. The effect and adverse drug reaction (ADR) of Diazepam were statistically analyzed. Results No ADR occurred in i.m. group and the effective rate was 92.31%. Although the effective rate in i.v. group was 100%, 3 patients suffered from cardiac arrest, 2 patients were found to have aspiration and apnea suddenly, and the ratio of ADR was 7.46%. Conclusion It is better to use intramuscular injection rather than intravenous injection in treating acute alcoholism with Diazepam, in order to avoid the serious medical incidents.
RESUMO
Objective To study the clinical features of spontaneous rupture of the right cardiac atrium. Methods Two cases of spontaneous rupture of right cardiac atrium were reported, and related literature was reviewed. Results Spontaneous rupture of the right cardiac atrium which was a rare disease, presented symptoms including stifling sensation in the chest, chest pain and symptoms of cardiac tamponade. The diagnosis should be differentiated with by ultrasonic examination and CT from cardiac infarction, cardiac rupture caused by external injury and dissecting aneurysm of aorta. Conclusion Spontaneous rupture of right cardiac atrium is rare disease, and an early diagnosis and prompt operation are necessary.
RESUMO
A c linical study is carried out by the death of acute severe disease and malignant consumptive disease.Results show that the cases of death of acute severe diseases and last salvage are far more than those of malignant consumptive diseases.Moreover,the relations bear more mental pains caused by death of acute severe diseases than by malignant consumptive diseases.
