Objective: To explore the effects of a zerotime exercise (ZTEx) intervention on physical activity levels and sedentary behavior among college students, providing evidence for improving physical activity and reducing sedentary habits. Methods: In September 2023, 45 sedentary college students from a university in Fuzhou were recruited and randomly assigned to either the ZTEx group (23 students) or the control group (22 students) according to a random number table method. ZTEx group received two ZTEx focus group meetings for 3 months, while the control group received safety and health education. The International Physical Activity Questionnaire and a threeaxis accelerometer were used to evaluate the sedentary and physical activity levels of college students. At the same time, evaluations related to physical health and psychological questionnaires were completed. Mixed effects analysis of variance and nonparametric tests were used to statistically analyze the physical health, psychological questionnaire, and sedentary and physical activity data of the college students. Results: Postintervention, the ZTEx group showed significant improvements in the duration of lowintensity physical activity [pretest(1 492.78±369.50)min; posttest(1 918.93±354.63)min] and the number of sedentary interruptions [pretest(45.26±13.69)times; posttest(73.78±16.74)times]; grip strength [pretest(28.77±9.23)kg; posttest(31.78±8.00)kg]; sitting up continuously for 30 seconds [pretest(22.52±4.90)times; posttest(26.96±4.87)times]; general selfefficacy [pretest(26.52±4.14)points; posttest(32.96±5.24)points]; body composition summary [pretest(66.44±4.83)points; posttest(72.62±4.88)points]; and psychological composition summary [pretest(61.21±9.88)points; posttest(63.98±9.57)points], while reducing sedentary time [pretest(3 694.28±687.56)min; posttest(2 865.90±493.81)min] in the past 7 days, the differences were statistically significant(P<0.05). The control group exhibited no significant changes(P>0.05). Conclusion ZTEx effectively improve the lowintensity physical activity, increases sedentary breaks, and reduces prolonged sitting among college students, fostering healthier habits and improving physical/mental wellbeing.

OBJECTIVES: This study aimed to analyze the application value of a modified tragus edge incision and transmasseteric anteroparotid approach to condyle reconstruction. METHODS: Condyle reconstruction was performed in 16 patients (9 females and 7 males) with modified tragus edge incision and transmasseteric anteroparotid approach. After regular follow-up, the function of condyle reconstruction was evaluated by clinical indicators, such as parotid salivary fistula, facial nerve function, mouth opening, occlusal relationship, and facial scar. The morphology of rib graft rib cartilage was evaluated by imaging indicators, such as panoramic radiography, CT, and three-dimensional CT image reconstruction. RESULTS: At 6-36 months postoperative follow-up, all patients had good recovery of facial appearance, concealed incisional scar, no parotid salivary fistula, good mouth opening, and occlusion. One case had temporary facial paralysis and recovered after treatment. Radiographic evaluation further showed that costochondral graft survived in normal anatomic locations. CONCLUSIONS The modified tragus edge incision and transmasseteric anteroparotid approach can effectively reduce parotid salivary fistula and facial nerve injury in condylar reconstruction. The surgical field was clearly exposed, and the incision scar was concealed without increasing the incidence of other complications. Thus, this approach is worthy of clinical promotion.

Objective:To compare the predictive value of parameters extracted from circular region-of-interest (ROI) with whole-liver histogram on gadoxetic acid disodium (Gd-EOB-DTPA)-enhanced T 1 map for postoperative liver failure in patients with liver focal lesions. Methods:The data of patients who underwent Gd-EOB-DTPA-enhanced MRI for focal liver lesions in Zhongshan Hospital, Fudan University from March 2016 to March 2018 were analyzed retrospectively. Forty patients were enrolled, including 30 males and 10 females, aged (56.6±12.1) years. According to the occurrence of postoperative liver failure, forty patients were divided into liver failure group ( n=14) and control group ( n=26). The parameters extracted from circular ROIs and whole liver histogram on T 1 map before Gd-EOB-DTPA enhancement and in hepatobiliary phase (HBP) were compared between the two groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of these parameters in predicting postoperative liver failure. Results:The mean, standard deviation, median and 95% quantile of T 1 HBP in histogram parameters of liver failure group were significantly higher than those of control group (all P<0.05). The three parameters extracted from circular ROIs were not effective in predicting liver failure after hepatectomy (all P>0.05). Among all the liver histogram parameters, the area under the ROC curve of the 95% quantile before T 1 enhancement for predicting postoperative liver failure was 0.702 (95% CI: 0.523-0.881), the standard deviation of T 1 HBP was 0.739 (95% CI: 0.568-0.910), and the 95% quantile of T 1 HBP was 0.721 (95% CI: 0.540-0.903). The predictive efficacy were good (all P<0.05). Among them, the predictive performance of T 1 HBP standard deviation was the best, the area under the ROC curve was 0.739, the sensitivity was 85.7%, the specificity was 57.7%, and the best threshold was 54.8 ms. Conclusions:When Gd-EOB-DTPA enhanced T 1 mapping is used to predict postoperative liver failure in patients with focal liver lesions, the whole-liver histogram analysis is superior to the conventional circular ROI-based statistical method.

Headache is a common clinical complication of ischemic stroke. As a precursor of stroke, headache occurs repeatedly in the convalescent period of ischemic stroke, leading to secondary stroke and seriously hindering patients' rehabilitation. Currently, it is believed that the pathogenesis of ischemic stroke-related headache is associated with the abnormal release of vasoactive substances, high platelet aggregation, and stimulation of intracranial pain-sensitive structures. The active ingredients in traditional Chinese medicines(TCM) with the effects of activating blood to resolve stasis and clearing heat to release exterior can protect brain tissue and relieve headache by reducing the release of inflammatory cytokines, alleviating antioxidant stress, inhibiting neuronal apoptosis and so on. This paper introduces the research progress in the potential mechanism and TCM treatment of ischemic stroke-related headache, aiming to provide reference for further research and drug development of this complication.

Moringa oleifera leaves are known for their "Virechana"(purgative) effect in Ayurvedic medicine in India. This study compared the purgative effects and mechanisms of M. oleifera leaves with the reference Rhei Radix et Rhizoma to establish a foundation for the further application of M. oleifera leaves in traditional Chinese medicine(TCM). Using network pharmacology and molecular docking methods, this study identified the material basis, common targets, and signaling pathways through which Rhei Radix et Rhizoma and M. oleifera leaves exerted their purgative pharmacological effects. A low-fiber diet-induced constipation mouse model was established to measure fecal parameters and small intestinal propulsion rate, and histological changes in the colon were observed using HE staining. Relative expression levels of relevant genes and target proteins were assessed using RT-qPCR and immunohistochemistry, respectively. The results showed that mapping the targets of Rhei Radix et Rhizoma and M. oleifera leaves onto the biological process network of constipation revealed close proximity, indicating that they may exert their therapeutic effects on constipation through similar biological processes. Molecular docking results indicated that compounds such as sennoside C and isoquercitrin could target serine/threonine protein kinases(AKT1) and mitogen-activated protein kinase 3(MAPK3), thereby affecting MAPK and calcium signaling pathways to promote defecation. Animal experiments demonstrated that both M. oleifera leaves and Rhei Radix et Rhizoma increased the number of fecal pellets and water content in constipated mice, improved small intestine motility, colon mucosal thickness, and muscle layer thickness, upregulated the gene expression levels of AKT1 and MAPK3 in the colon, and downregulated the expression of AQP3 protein. These findings suggest that M. oleifera leaves and Rhei Radix et Rhizoma share similarities in their therapeutic efficacy and mechanisms for treating constipation. Using Rhei Radix et Rhizoma as a reference can provide a better understanding of the characteristics of the "Virechana"(purgative) effect of M. oleifera leaves in TCM.

Psoriasis is characterized by abnormal proliferation of keratinocytes, as well as infiltration of immune cells into the dermis and epidermis, causing itchy, scaly and erythematous plaques of skin. The understanding of this chronic inflammatory skin disease remains unclear and all available treatments have their limitations currently. Here, we showed that IMMH002, a novel orally active S1P modulator, desensitized peripheral pathogenic lymphocytes to egress signal from secondary lymphoid organs and thymus. Using different psoriasis animal models, we demonstrated that IMMH002 could significantly relieve skin damage as revealed by PASI score and pathological injure evaluation. Mechanistically, IMMH002 regulated CD3 T lymphocytes re-distribution by inducing lymphocytes' homing, thus decreased T lymphocytes allocation in the peripheral blood and skin but increased in the thymus. Our results suggest that the novel S1P agonist, IMMH002, exert extraordinary capacity to rapidly modulate T lymphocytes distribution, representing a promising drug candidate for psoriasis treatment.

Objective:To analyze the related risk factors for vertebral artery tortuosity, and explore the mechanism of vertebral artery tortuosity.Methods:Two hundred and eighty-two patients accepted head/neck and MR angiography in our hospital from October 2016 to October 2017 were selected. The tortuosity degrees of vertebral artery were measured and calculated by PACS system. The differences of tortuosity degrees of vertebral arteries in different age groups were compared. Correlation analysis was performed to determine the correlation between vertebral artery tortuosity and both clinical data and and biochemical levels, and multivariate linear regression analysis was performed to determine the independent risk factors for vertebral artery tortuosity.Results:The tortuosity degrees of the left and right vertebral arteries in these patients ranged from 5.1% to 72.6%. The tortuosity degrees of vertebral arteries in patients aged 40-49 years were significantly higher than those in patients aged 20-29 years and 30-39 years ( P<0.05). Correlation analysis showed that the tortuosity degree of the right vertebral artery was positively correlated with age and triglyceride level ( r=0.232, P=0.000; r=0.172, P=0.004); the tortuosity degree of the left vertebral artery was positively correlated with triglyceride level ( r=0.123, P=0.043). Multivariate regression analysis showed that age ( 95%CI: 0.059-0.194, P=0.000) and triglyceride level ( 95%CI: 0.173-1.942, P=0.019) were independent risk factors for right vertebral artery tortuosity. Triglyceride level ( 95%CI: 0.041-2.559, P=0.043) was independent risk factor for left vertebral artery tortuosity. Conclusion:There are congenital developmental factors associated with vertebral artery tortuosity; some nurture factor, as triglyceride level, may promote its development.
