ABSTRACT
Objective@#The study aimed to investigate the relationship between academic stress and extracurricular physical exercise among college students, with the goal of providing evidence and reference for effectively alleviating academic stress.@*Methods@#A stratified cluster random sampling method was employed, along with the Chinese College Student Psychological Health Screening Scale and a self designed questionnaire. In January 2023, an online survey was conducted among 1 108 college students from eight colleges and universities in Jiangsu Province. Statistical analyses included independent samples t test, one way analysis of variance (ANOVA) and the optimal scale regression model.@*Results@#It revealed that 50.8% of students worried about falling behind their peers in their studies, 51.7% expressed concerns about exams, 21.7% exerted significant effort but still struggled to keep up with the pace of learning, and 24.9% felt difficulties in their studies. The overall index of academic stress was higher among undergraduate institutions, first year students, female students, and urban residents ( t/F =3.66, 10.96, -5.46, 3.52, P <0.01). The average time of weekly extracurricular physical exercise for students was (2.35±2.18)h, and there were significant differences by gender, only child status, and grade groups( t/F =2.35, 4.66, 7.09, P <0.05). The optimal scale regression model analysis ( R 2=0.17, F=32.03, P <0.01) revealed that the regression coefficient and partial correlation coefficient between academic stress and extracurricular physical exercise time were both -0.33( P <0.01). The importance of extracurricular physical exercise in the model was 0.66, with a tolerance value of 0.97. The regression coefficients and partial correlation coefficients for academic stress and extracurricular physical exercise time were -0.35, -0.35 for undergraduate students, and -0.31, -0.32 for junior college students ( P < 0.01 ).@*Conclusion@#A significant number of college students experience varying degrees of academic stress, and their engagement in extracurricular physical exercise is insufficient. There is a negative association between academic stress and extracurricular physical activity time among college students. Universities should encourage students to increase extracurricular physical activity time to reduce academic stress and promote college students mental health.
ABSTRACT
The microscopic identification technique plays an important role in quality standard of Chinese herbal medicines. It has been adopted as a routine identification method in the major pharmacopoeias due to its accurate, simple, speedy, inexpensive, feasible as well as environmentally friendly properties. In this article, the theoretical principles of microscopic identification, the stability and specificity of microscopic characters, are firstly discussed. The applications of microscopic identification in ChP, USP, Ph. Eur. and JP are listed and typically compared. A protocol for microscopic identification is thus proposed based on our previous investigations. Finally, some challenges facing modernizaiton of Chinese herbal medicines are also outlined.
ABSTRACT
Objective The purpose of this study was to observe the effects of bumetanide on elderly type 2 diabetic patients with middle and advanced stages nephropathy. Methods Forty cases with diabetic nephropathy (DN) were divided into two groups:control group (20 cases) and treatment group (20 cases) . The control group accepted furosemide (20 mg, once a day) and the bumetanide was orally administrated at the dose of 1.0 mg, twice a day to the treatment group for 3 months. The assessment of transferrin (TRF) and urine microalbumin (UALB) was performed at the time points at the end of 1, 4, 8, 12 weeks after treatment. Results (1) The levels of BUN, SCr and UA after treatment were lower than before treatment, but there were no significant differences. (2) In the treatment group, the levels of TRF and UALB have decreased after treatment for 1 week, with no statistically significant. But at the end of 4, 8 and 12 weeks,the differences were statistically significant ( <0.05) . Especially, during the three months follow-up,the levels of TRF and UALB at 12 weeks have decreased obviously. Conclusion The therapeutic effect of bumetanide on DN might be better than that of furosemide.
ABSTRACT
Objective To check the changes of endothelial progenitor cell (EPC) number of patients with anaplastic large cell lymphoma (ALCL) in the peripheral blood,investigate their clinical significance.Methods The number of EPC in blood was determined by FCM method in 30 patients with ALCL and 10 healthy cases as the control group.Results The number of EPC in the peripheral blood of patients with ALCL before treatment was significantly higher (15.530±28.659/μl) than that in control group (0.515 ±0.294/μl,P ＜ 0.001).The number of EPC of ALCL patients in the high-risk groups (21.521±36.057/μl) and the middle-risk groups (16.830±24.273/μ1) differently increaasd than that of the low-risk group (6.508±7.356/μl,P ＜ 0.01),but between the high-risk groups and the middle-risk groups there was no significant value (P ＞ 0.05).There were significant difference between the number of EPC of ALK+-ALCL (8.367±9.609/μl) and ALK-ALCL (22.541± 20.845/μl) patients (P ＜ 0.01).The survive curve before 60 weeks had significant difference between groups of ＞20/μl and ＜20/μl of EPC.Conclusion EPC may be correlated with progression of the disease in a certain degree.Dynamic observation with the level of EPC may be used to evaluate the treatment outcomes and act as a prognostic marker for ALCL.
ABSTRACT
Objective The changes of CECs,EPCs and CPCs in the old type 2 diabetes mellitus retinopathy(DR)patients and the clinical purpose were discussed.Methods 30 cases of T2DM(including 10 DM cases without complications and 20 DM cases with retinopathy)and 10 cases of health controls were enrolled in this study.Results(1)The changes of CECs in DR Patients were significantly higher while the levels of EPCs and CPCs were significantly lower than those in the patients of the control group.(2)There were some corrlation beteen the level of CECs,EPCs and CPCs and the degree of diabetic retinopathy.(3)The serum EPCs levels in type 2 diabetics were negativey associated with body mass index,waist-hip ratio,abdominal circumference,FPG,triglyceride,UAER,creatinine.Conclusion The levels of EPCs and CPCs in T2DM-DR patients may be the important detected targets for early discovery and monitoring of DR.
