		                        			BACKGROUND:The causal relationship between modifiable factors such as lifestyle,metabolic characteristics,and nutritional intake and joint sports injuries has been increasingly recognized in clinical studies.However,the exact causal relationship between these modifiable factors and joint sports injuries remains unclear. OBJECTIVE:To investigate the causal relationship between modifiable factors and joint sports injuries using Mendelian randomization to provide a basis for sports injury prevention. METHODS:The GWAS dataset of intervening factors and joint sports injuries was obtained from publicly available data.The causal relationships between lifestyle,metabolic characteristics,nutritional intake,and joint sports injuries were explored using the inverse variance weighting method,the MR-Egger method,and the weighted median method.For sensitivity analyses,Cochran's Q test,MR-Egger regression,leave-one-out method,and MR-PRESSO were used to verify the stability and reliability of the results. RESULTS AND CONCLUSION:(1)In terms of lifestyle,coffee(OR=0.29,95%CI:0.10-0.79,P=0.016),and tea consumption(OR=0.41,95%CI=0.19-0.85,P=0.017)were associated with a decreased risk of ankle and foot joint sports injuries,and coffee consumption(OR=3.31,95%CI=1.02-10.73,P=0.046)was potentially causally associated with an increased risk of shoulder joint sports injuries;and never smoking(OR=0.78,95%CI=0.70-0.87,P=1.49×10-5)was significantly causally associated with a decreased risk of ankle and foot joint sports injuries.(2)In terms of metabolic characteristics,calcium levels(OR=0.88,95%CI=0.79-0.98,P=0.017)were potentially causally associated with a decreased risk of wrist and hand joint sports injuries.(3)In terms of nutritional intake,vitamin A intake(OR=1.08,95%CI:1.02-1.13,P=0.007)was potentially causally associated with increased risk of knee joint sports injury.(4)For the sensitivity analysis,Cochran's Q test showed the existence of heterogeneity(P<0.05),so the random effect model was used for the analysis.MR-Egger regression and MR-PRESSO test did not find evidence of pleiotropy(P>0.05),and the leave-one-out method showed that the results were stable after eliminating single nucleotide polymorphisms one by one.(5)This study preliminarily reveals the effects of modifiable factors,such as lifestyle,metabolic characteristics,and nutritional intake,on the risk of joint sports injuries.It provides valuable research evidence and guidance for the prevention of joint sports injuries.

		                        			BACKGROUND:Clinical evidences have suggested a correlation between metabolic factors and sarcopenia.Blood metabolites have been found as biological factors underlying the mechanisms of musculoskeletal disorders.However,the causal relationship between blood metabolites and sarcopenia is unclear. OBJECTIVE:To explore the causal relationship between blood metabolites and sarcopenia-related traits through a two-sample Mendelian randomization analysis and to analyze their metabolic pathways. METHODS:A dataset of 486 blood metabolites and sarcopenia-related traits was obtained from public databases.The inverse variance weighting,MR-Egger and weighted median methods were used to assess the causal relationship of blood metabolites with muscle mass and strength across genders.Sensitivity analyses,including heterogeneity and gene pleiotropy,were performed to explore the robustness of the results.Metabolic pathway analysis of potential causal relationships was performed using the Metaboanayst 5.0 tool. RESULTS AND CONCLUSION:A total of 124 metabolites and sarcopenia-related traits were observed to have potential causal relationships(P<0.05).Mannose and 1-arachidonoylglycerophosphocholine were significantly causally associated with an increased muscle mass in males(P<1.03×10-4).Pentadecanoate and glycine were significantly causally associated with decreased muscle mass and muscle strength in females,respectively(P<1.03×10-4).Metabolic pathway analysis identified eight metabolic pathways associated with altered levels of muscle mass and muscle strength in sarcopenia,including the"glyoxylate and dicarboxylate metabolism"and"Glycine,serine and threonine metabolism."The identified metabolites are considered as useful circulating metabolic biomarkers for screening and prevention of sarcopenia in clinical practice,serving as candidate molecules for future mechanistic exploration and drug target selection.

		                        			Objective  To assess the efficacy and safety of ascending aorta banding technique combined with typeⅠhybrid aortic arch repair for the aortic arch diseases. Methods  The clinical data of patients undergoing ascending aorta banding technique combined with type Ⅰ hybrid arch repair for aortic arch diseases from March 2019 to March 2022 in Beijing Anzhen Hospital were retrospectively analyzed. The technical success, perioperative complications and follow-up results were evaluated. Results  A total of 44 patients were collected, including 35 males and 9 females, with a median age of 63.0 (57.5, 64.6) years. The average EuroSCORE Ⅱ score was 8.4%±0.7%. The technical success rate was 100.0%. All patients did not have retrograde type A aortic dissection and endoleaks. One patient died of multiple organ failure 5 days after operation, the in-hospital mortality rate was 2.3%, and the remaining 43 patients survived and were discharged from hospital. The median follow-up period was 14.5 (6-42) months with a follow-up rate of 100.0%. One patient with spinal cord injury died 2 years after hospital discharge. One patient underwent thoracic endovascular aortic repair at postoperative 3 months due to new entry tears near to the distal end of the stent. Conclusion  Ascending aorta banding combined with typeⅠhybrid arch repair for the aortic arch diseases does not need cardio-pulmonary bypass. Ascending aorta banding technique strengthens the proximal anchoring area of the stent to avoid risks such as retrograde type A dissection, endoleak and migration. The operation owns small trauma, rapid recovery, low mortality and a low rate of reintervention, which may be considered as a safe and effective choice in the treatment of the elderly, high-risk patients with complex complications.
