Objective:To observe the clinical efficacy of unilateral biportal endoscopy (UBE) assisted bilateral decompression in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side.Methods:A total of 20 patients with lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side treated with UBE from January 2022 to January 2024 in the Affiliated Hospital of Binzhou Medical University were retrospectively analyzed. There were 9 males and 11 females, aged 50.4±14.0 years (range, 23-72 years). The intervertebral disc herniation level included L 3-4 in 1 case, L 4-5 in 15 cases, and L 5S 1 in 4 cases. There were 10 cases on the left side and 10 cases on the right side. The duration of symptoms was 24.1±33.7 months (range, 1-120 months). Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate postoperative pain relief and functional recovery. The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Results:All patients successfully completed the operation. The operation time was 90.3±24.6 min (range, 55-134 mins). The VAS scores of patients at 3 days, 1 month, 3 months and 6 months after operation were 3.6±0.9, 2.2±0.7, 1.2±0.5 and 1.0±0.6, respectively, which were lower than those before operation (6.4±0.8), and the differences were statistically significant ( F=668.728, P<0.001). The ODI at 3 days, 1 month, 3 months and 6 months after operation were 34.2%±4.7%, 28.7%±2.8%, 24.3%±2.1% and 20.5%±2.0%, respectively, which were lower than 69.4%±5.2% before operation, and the differences were statistically significant ( F=515.578, P<0.001). The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Among 20 patients, 18 cases were excellent, 1 case was good, and 1 case was fair. All patients were followed up for 9.1±2.1 months (range, 6-14 months). One patient had a dural tear during the operation, but the range was small and there was no defect, and no further treatment was performed. Numbness of the lower limbs occurred 1 day after operation, and the symptoms disappeared after symptomatic treatment. There was no recurrence of lower limb symptoms, lumbar instability, intervertebral space infection or other complications at the last follow-up. Conclusion:Bilateral decompression with UBE is effective in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side, which can improve the lumbar pain and function of patients.

Objective To explore the association between aspartate aminotransferase(AST)/alanine aminotransferase(ALT)ratio and metabolic syndrome(MS)in elderly hypertensive patients,and to provide reference for early detection and prevention of MS in elderly hypertensive patients.Methods A questionnaire survey and physical examination were conducted among 616 elderly hypertensive patients at community health service centers.Participants were divided into two groups based on MS status:MS group(n=334)and non-MS group(n=282).According to AST/ALT levels,participants were divided into four groups:q1 group(AST/ALT ≤0.88,n=156),q2 group(0.88＜AST/ALT ≤ 1.10,n=155),q3 group(1.10＜AST/ALT ≤ 1.37,n=154),and q4 group(AST/ALT＞1.37,n=151).Blood biochemical parameters including triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),AST,ALT,and blood glucose were measured.The impact of AST/ALT levels on MS was analyzed using a Logistic regression model,while the risk prediction for MS occurrence was evaluated through receiver operating characteristic(ROC)curves.Results MS group showed higher body mass index(BMI),TG,ALT levels,abnormal glucose levels,female proportion,and abdominal obesity rate compared to non-MS group.HDL-C and AST/ALT values of MS group were lower than those in non-MS patients(P＜0.05).Logistic regression analysis revealed that after adjusting for BMI,smoking,alcohol consumption,physical activity,education level,marital status,TG,HDL-C,and glucose levels,both q3 and q4 groups demonstrated reduced MS risk compared to group q1 group(P＜0.05).ROC curve analysis indicated that the area under the curve for AST/ALT in MS was 0.638(P＜0.05).Conclusion The level of AST/ALT was negatively correlated with MS in elderly hypertensive patients,and AST/ALT has certain predictive value for the risk of MS in elderly hypertensive patients.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective To compare the clinical efficacy of digital 3D technology assisted and traditional one-hole split endoscopic surgery for lumbar spinal stenosis with degenerative scoliosis(LSS-DS).Methods Clinical data of 42 patients with LSS-DS who underwent one-hole split endoscopic surgery from January 2022 to December 2023 were retrospectively analyzed.Among them,20 cases were treated with digital 3D technology assisted one-hole split endoscopic surgery(3D group),and 22 cases were treated with traditional one-hole split endoscopic surgery(traditional group).The operation time,intraoperative blood loss,lateral articular surface preservation rate,Visual Analogue Scale(VAS)of lower extremity pain,Oswestry Disability Index(ODI)and modified MacNab criteria at the last follow-up were compared between the two groups.Results Both groups of patients were operated successfully.The operation time of the 3D group and the traditional group was(73.3±24.0)min and(65.7±23.8)min,respectively,with no significant difference(t=1.020,P=0.314).The intraoperative blood loss was(65.3±14.7)ml and(66.7±17.1)ml,respectively,with no significant difference(t=-0.298,P=0.767).The retention rate of lateral articular surface in the 3D group[(88.2±6.3)%]was significantly higher than that in the traditional group[(82.7±4.6)%,t=3.201,P=0.003].One patient in the traditional group had dural tear and was cured after conservative treatment.There were 3 cases of calf muscle venous thrombosis in the 3D group and 4 cases in the traditional group.All the 7 patients were given anticoagulant therapy and appropriately delayed time of ambulation.In the3D group,20 cases were followed up for6-13 months,with a mean of(8.2±2.0)months;in the traditional group,22 cases were followed up for 6-12 months,with a mean of(7.7±1.7)months.According to the modified MacNab criteria,the excellent and good rate was 95.0%(19/20)in the 3D group and 90.1%(20/22)in the traditional group at the last follow-up,and there was no significant difference between the two groups(Z=-0.311,P=0.756).The VAS score and ODI of the two groups were significantly improved at 3 months and 6 months after operation(all P=0.000),but there was no significant difference between the two groups at each time point(P>0.05).Conclusion The short-term efficacy of digital 3D technology assisted one-hole split endoscopic surgery in the treatment of LSS-DS is definite,and the symptoms of patients are significantly improved.

Objective:To investigate the expression of NADPH oxidase(Nox)in chronic obstructive pulmonary disease(COPD).Method:The rats were randomly divided into control group,COPD group,COPD medium exercise group and COPD intensive exercise group,with 10 rats in each group.The expression of NADPH oxidase,hypoxia induc-ible factor-1 alpha(HIF1α),inflammatory factors tumor necrosis——factor alpha(TNFα),interleukin-6(IL-6),matrix metalloproteinase 2(MMP-2)and matrix metalloproteinase 9(MMP-9)were detected by immunohistochemistry.Result:Compared with the control group,the expression of NADPH oxidase subtypes Nox1,Nox2,Nox5,HIF1α,TNFα,IL-6,MMP-2 and MMP-9 in COPD group increased significantly.Medium exercise reduced the expression of Nox2,Nox5,HIF1α and MMP-9 in COPD animal model,while intensive exercise reduced the expression of Nox1,Nox2,Nox5,HIF1α,TNFα,IL-6 and MMP-9.Conclusion:Rehabilitation exercise down regulated the expression of NADPH oxidases in lung,reduced the expression of downstream inflammatory factors and matrix metalloproteinase.The protective function of rehabili-tation exercise might achieve by inhibiting the expression of hypoxia inducible factor.
