Objective: This study aimed to explore the relationships between various exercise components (frequency, intensity, duration) and social anxiety. Methods: A sample of 844 college students in China participated in this study. The Physical Activity Rating Scale-3 assessed participants’ daily physical activity. Social anxiety levels were measured using the Liebowitz Social Anxiety Scale. A questionnaire was developed to collect demographic information and examine the relationships between exercise components and social anxiety levels. Results: One-way analysis of variance revealed significant differences in social anxiety levels across varying physical activity intensities. Specifically, students engaging in high levels of physical activity exhibited the lowest social anxiety. Post hoc analyses identified that exercise frequency F3 (p<0.01), exercise duration D5 (p<0.01), and exercise intensity I3 (p<0.01) were significantly associated with the lowest social anxiety levels. Among these components, regression analysis indicated that exercise duration (p<0.01) had the most substantial impact on social anxiety levels, followed by exercise frequency (p<0.05). In contrast, exercise intensity (p>0.05) did not significantly affect social anxiety levels. Conclusion The most influential factors associated with decreased social anxiety were: 1) moderate to high exercise intensity, 2) exercise duration of at least one hour, and 3) exercise frequency of at least 1–2 times per week. Among these factors, exercise duration and frequency demonstrated significantly stronger associations with reduced social anxiety. Therefore, it is advisable to prioritize exercise duration and frequency in physical activity programs for college students to reduce social anxiety and achieve more substantial outcomes.

ObjectiveTo investigate the effects of rhizosphere organic acids secreted by the roots of Salvia miltiorrhiza on continuous cropping obstacles. MethodsThe mixed solution of organic acids in the rhizosphere of S. miltiorrhiza in continuous cropping and rotation cropping was added to the hairy roots subcultured for 21 days， and samples were collected on days 0， 2， 4， 6， 8， and 10. The changes of biomass， effective components， primary metabolites， secondary metabolites， antioxidant enzymes， and hormones in hairy roots of S. miltiorrhiza were observed and determined. ResultsCompared with the rotation cropping group and the blank control group， the simulation of organic acid secretion from the roots of S. miltiorrhiza had a significant inhibitory effect on the growth of hairy roots and decreased the content of effective components as well as total sugar and total protein in primary metabolites. Compared with the blank control group， the rotation cropping group and the continuous cropping group showed total sugar and total protein content decreases of 33.9% and 5.1%， respectively. On the other hand， the secretion of organic acids from S. miltiorrhiza roots significantly promoted the accumulation of total phenolic acids and total tanshinone， which showed increases of 14.6% and 1.6%， respectively， in continuous cropping group and rotation cropping group compared with the blank control group. ConclusionThe organic acid environment under continuous cropping significantly inhibited the growth of hairy roots and the accumulation of primary metabolites， while promoting the synthesis and accumulation of secondary metabolites of S. miltiorrhiza.

Objective:To study the distribution of TCM constitutions in maintenance hemodialysis (MHD) patients.Methods:This is a multicenter cross-sectional study. The general clinical data, dialysis-related parameters and physical and chemical examination data of MHD patients from 6 dialysis centers in Sichuan were collected. At the same time, DS01-A tongue and facial pulse information collection system was used for TCM constitution discrimination.Results:A total of 232 MHD patients were enrolled , and 417 kinds of TCM constitutions were detected, including 59 patients (25.43%) with moderate constitution and 173 patients (74.57%) with biased constitution. Phlegm-dampness was the most common type of solid constitution 47 patients (20.26%). The most common deficiency constitution was qi deficiency 86 patients (37.07%). There were certain differences in the physical distribution of patients with different gender, age, dialysis age, BMI, and whether they had diabetes, hypertension or anemia.Conclusions:The TCM constitutions of MHD patients are mainly biased constitution. Gender, age, BMI, diabetes or hypertension have a certain impact on the distribution of TCM constitutions. At the same time, different constitutions may have an impact on the anemia of MHD patients. The intervention of TCM constitutions on MHD patients may be beneficial to the prognosis of MHD patients.

OBJECTIVE To investigate the effect of leech freeze-dried powder combined with scorpion freeze-dried powder on carotid artery thrombosis in rats. METHODS FeCl3 was used to induce carotid artery thrombosis, and the experiment was divided into 6 groups: sham-operated group(sham group), model group, leech freeze-dried powder group(leech group), whole scorpion freeze-dried powder group(scorpion group), leech+scorpion half-dose group(half-dose group), leech+scorpion full-dose group(full-dose group), 6 rats in each group. The inhibition rate of bilateral carotid artery thrombosis was calculated after the final administration. The activated partial thromboplastin time(APTT), plasma prothrombintime(PT), plasma fibrinogen(FIB), and prothrombin time(TT) were measured by platelet aggregation and coagulation factor analyzer. The levels of plasma tissue-type plasminogen activator(t-PA) and plasminogen activatorinhibitor-I(PAI-I) were measured by ELSIA, and the thrombosis of each group was observed by HE staining. RESULTS Compared with model group, the wet weight and dry weight of thrombus were reduced in the leech, scorpion, half-dose and full-dose groups, and the full-dose group had the best effect in inhibiting thrombus formation. Compared with sham group, APTT, PT, TT was shortened, FIB content increased and t-PA level decreased in model group; compared with model group, APTT, PT, TT was prolonged, FIB content decreased and t-PA level increased in each dose group. The PAI-Ⅰ was not significantly different in each group. A large number of thrombus were seen in the blood vessels of model group. Compared with model group, there were significantly fewer thrombus in the leech, scorpion and half-dose groups, and almost no significant thrombus in the full-dose group. CONCLUSION Leech freeze-dried powder combined with scorpion freeze-dried powder inhibited carotid artery thrombosis in rats by affecting coagulation function and fibrinolytic system.

Objective To campare biomechanical effects of different postural compression techniques on three-dimensional model of lumbar disc herniation(LDH)by finite element analysis.Methods Lumbar CT image of a 48-year-old female patient with LDH(heighted 163 cm,weighted 53 kg)was collected.Mimics 20.0,Geomagic Studio,Solidwords and other software were used to establish three-dimensional finite element model of LDH on L4,5 segments.Compression techniques under horizon-tal position,30° forward bending and 10° backward extension were simulated respectively.After applying the pressure,the ef-fects of compression techniques under different positions on stress,strain and displacement of various tissues of intervertebral disc and nerve root were observed.Results L4,5 segment finite element model was successfully established,and the model was validated.When compression manipulation was performed on the horizontal position,30° flexion and 10° extension,the annular stress were 0.732,5.929,1.286 MPa,the nucleus pulposus stress were 0.190,1.527,0.295 MPa,and the annular strain were 0.097,0.922 and 0.424,the strain sizes of nucleus pulposus were 0.153,1.222 and 0.282,respectively.The overall displace-ment distance of intervertebral disc on Y direction were-3.707,-18.990,-4.171 mm,and displacement distance of nerve root on Y direction were+7.836,+5.341,+3.859 mm,respectively.The relative displacement distances of nerve root and interverte-bral disc on Y direction were 11.543,24.331 and 8.030 mm,respectively.Conclusion Compression manipulation could make herniated intervertebral disc produce contraction and retraction trend,by increasing the distance between herniated interverte-bral disc and nerve root,to reduce symptoms of nerve compression,to achieve purpose of treatment for patients with LDH,in which the compression manipulation is more effective when the forward flexion is 30°.
