OBJECTIVE:Prolonged sedentary behavior can acutely reduce peripheral and central vascular function,thereby increasing the risk of cardiovascular disease.Interrupting sedentary behavior may be a potential practical strategy to prevent vascular dysfunction caused by prolonged sitting.However,current research findings on its acute effects are inconsistent,and specific application recommendations have not yet been established.This study aims to perform a Meta-analysis on the acute effects of interrupting sedentary behavior on peripheral and central vascular function in adults and to explore its regulatory factors.METHODS:Following PRISMA reporting guidelines,literature search was conducted in March 2024 using the keywords of"interrupting,""sedentary,"and"vascular function"in the Web of Science Core Collection,PubMed,and China National Knowledge Infrastructure(CNKI)databases.Acute randomized crossover trials addressing the acute effects of interrupting sedentary behavior on peripheral and central vascular function in adults were included.Risk of Bias 2 developed by Cochrane was used to assess bias risk,and the Grading of Recommendations Assessment,Development,and Evaluation(GRADE)system was used to evaluate the evidence level.The"meta"and"metaphor"packages in R(version 4.2.0)were used for main effect aggregation(Hedge's g acted as the effect size indicator),publication bias testing,subgroup analysis,and regression analysis.RESULTS:Twenty-two randomized crossover trials involving 364 subjects(aged 21 to 70 years)were included.Meta-analysis results showed that compared with prolonged sitting,interrupting sedentary behavior acutely improved peripheral vascular blood flow volume(Hedge's g=0.48,95%confidence interval:0.14-0.82,P<0.01,I2=63%,low evidence level),shear stress(Hedge's g=0.65,95%confidence interval:0.37-0.93],P<0.01,I2=54%,moderate evidence level),and flow-mediated dilation(Hedge's g=0.43,95%confidence interval:0.15-0.72,P<0.01,I2=61%,moderate evidence level).Disease had a significant moderating effect on the main effect aggregation for blood flow volume(P=0.01 between subgroups),while the mode(P=0.01 between subgroups)and frequency(P=0.02 between subgroups)of interruptions had significant moderating effects on shear stress.Improvements in peripheral vascular shear stress from interrupting sedentary behavior were affected by age(β=-0.02,95%confidence interval:-0.03-0.01,P=0.09)and body mass index(β=-0.10,95%confidence interval:-0.18 to-0.02,P<0.01).Improvements in flow-mediated dilation were influenced by the total number of interruptions(β=-0.09,95%confidence interval:-0.17 to-0.01,P=0.03)and the duration of sitting during the control period(β=-0.21,95%confidence interval:-0.34 to-0.09,P<0.01).Each additional hour of sitting was associated with a 0.67%reduction in the acute improvement effect of flow-mediated dilation from interrupting sedentary behavior(P<0.01),and acute benefits disappeared when sitting control time exceeded 6 hours.A qualitative systematic review found that interrupting sedentary behavior did not significantly affect pulse wave velocity in various populations but could effectively prevent central vascular function decline in older adults due to prolonged sitting.CONCLUSION:Interrupting sedentary behavior acutely improves peripheral vascular blood flow volume(low evidence level),shear stress(moderate evidence level),and flow-mediated dilation(moderate evidence level)in adults and may prevent or protect against central vascular function decline in older adults due to prolonged sitting(very low evidence level).Characteristics of subjects(disease factors,sex,age,and body mass index),interruption intervention schemes(mode,frequency,total number of interruptions),and duration of sitting control all influence the acute improvement effects of interrupting sedentary behavior on vascular function.It is recommended that adults interrupt sedentary behavior with exercises involving large muscle groups,such as stair climbing,at high frequencies(e.g.,once every 40 minutes)with at least 5 minutes of moderate-to low-intensity activity each time,and limit the cumulative duration of prolonged sitting to no more than 6 hours per day.

Allergic rhinitis(AR)affects 10%-40%of the population in the world.Because CLOCK genes regulate the circadian rhythms of AR,the symptoms in parts of the patients are aggravated in the morning and evening and relieved at moon.Although lots of studies showed that traditional Chinese medicine is effective for AR,further explores are still needed to analyze the circadian rhythm of AR based on Chinese Chronological Medicine for controlling the circadian outbreak point of symptoms of AR in daily cycle.We supposed that Weiyang might play an important role for controlling the circadian rhythm of AR with closed similarities with the tidal variation of the expressions of CLOCK genes.Thus based on Weiyang theory,we tried to clarify the mechanism of circadian rhythm of AR and explore the relationship between Weiyang and the CLOCK genes so as to further expand the treatment methods of adjusting the circadian cycle of AR with TCM and improve the corresponding therapeutic efficacy.

ObjectiveTo explore the clinical effectiveness and safety of stick-point sinew-soothing and bone-setting manipulation for scapulohumeral periarthritis. MethodsUsing prospective randomised controlled trial method， 60 cases of patients with scapulohumeral periarthritis were collected and randomly divided into 30 cases each in control group and trial group. Both groups of patients were orally treated with celecoxib， on the basis of which the control group was treated with traditional bonesetting manipulation once every other day for 14 days， while the trial group was treated with stick-point sinew-soothing and bone-setting manipulation once every 3~5 days for 14 days. Both groups were treated for 2 courses. The main observation indexes were pain visual analogue scale （VAS） score and shoulder pain and dysfunction index （SPADI）， which were evaluated once before treatment and after 2 and 4 weeks of treatment. The secondary effectiveness indicators included the university of California at Los Angeles shoulder rating scale （UCLA）， traditional Chinese medicine syndrome score （including symptom scores as joint pain， pain in a fixed place， activity limitation， local stiffness）， and serum interleukin （IL-6） and tumour necrosis factor α （TNF-α） levels before and after the treatment， in order to evaluate the clinical effectiveness， and to record the adverse reactions that occurred in the process of diagnosis and treatment. ResultsCompared with the groups before treatment， the pain VAS score， SPADI and scores of joint pain， pain with a fixed place， activity limitation and local stiffness were lower， UCLA score was higher， and serum IL-6 and TNF-α levels were lower at 4 weeks of treatment in the two groups （P＜0.05）. When comparing the two groups between the groups at 2 and 4 weeks of treatment， the pain VAS score， SPADI and TCM scores of each symptom in the study group were lower than those in the control group， the UCLA score was higher than those in the control group （P＜0.01）， and the serum IL-6 and TNF-α levels were lower than those in the control group at 4 weeks of treatment （P＜0.01）. The clinical effectiveness rate of the study group was 66.67%， which was significantly higher than that of the control group， which was 40.00% （P = 0.038）. No adverse reactions were seen in both groups during the study. ConclusionCompared with the traditional massage manipulation， the treatment of scapulohumeral periarthritis with stick-point sinew-soothing and bone-setting manipulation has more advantages in relieving pain symptoms， reducing inflammatory reaction， and promoting the recovery of shoulder joint function.

Objective To elucidate the therapeutic mechanism of Qingxin Jieyu Granule(QXJYG)against atherosclerosis(AS)based on network pharmacology.Methods The major targets and pathways of QXJYG against AS were analyzed using network pharmacology.Rat models of AS established by high-fat feeding combined with intraperitoneal vitamin D3 injection were treated daily with normal saline,atorvastatin(13.15 mg/kg),or QXJYG at 0.99,1.98,and 3.96 g/kg for 8 weeks(n=6).Ultrasound and HE staining were used to assess the function and pathologies of the abdominal aorta.Blood lipids and serum levels of Ang II,ET-1,TXA2,PGI2,and ox-LDL of the rats were detected using an automatic biochemical analyzer or ELISA.The expressions of LOX-1,PPARγ,RXRα,p-P65,VCAM-1 and ICAM-1 in the abdominal aorta were detected with immunohistochemistry.Results The rat models of AS showed obvious abdominal aorta wall thickening,increased pulse wave velocity and pulse index,decreased inner diameter of the abdominal aorta,elevated levels of TC,LDL-C,Ang II,ET-1 and TXA2,and lowered levels of HDL-C and PGI2.QXJYG and atorvastatin treatment of the rat models significantly alleviated histopathological changes of the abdominal aorta,decreased serum levels of TC,LDL-C,Ang II,ET-1 and TXA2,and increased the levels of HDL-C and PGI2.Network pharmacology study suggested the therapeutic effect of QXJYG against AS was mediated by regulating lipid metabolism,PPAR and NF-κB pathways.Consistently,treatments with QXJYG were found to significantly decrease ox-LDL level and LOX-1,P-P65,VCAM-1 and ICAM-1 protein expressions while increasing PPARγ and RXRα expressions in the aorta of AS rats.Conclusion QXJYG alleviates lipid metabolism disorder and improves histopathological changes of the abdominal aorta of AS rats possibly by lowering ox-LDL level,reducing LOX-1 expression,activating PPARγ and RXRα,and inhibiting P65 phosphorylation to reduce VCAM-1 and ICAM-1 expression in the aorta.
