Objective To perform a regression analysis on the predictive value of serum micro-RNAs(miR)for early neurological deterioration(END)in patients with branch atheromatous dis-ease(BAD).Methods A total of 134 BAD patients admitted in our department from February 2020 to February 2023 were enrolled,and according to the END status,they were divided into de-terioration group(28 cases)and non-deterioration group(106 cases).Serum levels of miR-130a,miR-210,miR-141-3p and miR-29a-3p were measured at admission.NIHSS score was used to eval-uate the END status at admission and at 7 d after admission.Binary logistic regression analysis was adopted to construct a model of above four miRs in predicting END in BAD patients.ROC curve was plotted to assess the predictive value of the four miRs alone or combined together for END.Results The serum levels of miR-130a and miR-210 were significantly higher,while those of miR-141-3p and miR-29a-3p were obviously lower in the deterioration group than the non-deterioration group(P＜0.01).Logistic regression analysis indicated that serum miR-130a,miR-210,miR-141-3p and miR-29a-3p were independent predictors of END in BAD patients(P＜0.05,P＜0.01).ROC curve analysis showed that the AUC value of the four miRs combined together in predicting END in BAD patients was 0.977(95％CI:0.936-0.995),with a sensitivity of 96.43％and a specificity of 90.57％,and the combined detection exhibited better predictive effi-ciency than each indicator alone(P＜0.01).Conclusion Serum miR-130a,miR-210,miR-141-3p and miR-29a-3p have certain value in predicting END in BAD patients,and their combined detec-tion can enhance its predictive efficiency.

Objective To analyze the relationship between serum angiopoietin-like protein 8(ANGPTL8)and semaphorin 3A(Sema 3A)levels and postoperative cerebral vasospasm(CVS)in patients with intracranial aneurysm(IA)rupture.Methods A total of 188 patients with IA rupture receiving surgical treatment in our hospital were prospectively selected during October 2021 and October 2023,and according to whether CVS occurred after surgery,they were classified into a spasm group(75 cases)and a non-spasm group(113 cases).Serum ANGPTL8 and Sema 3A levels were measured after admission.Spearman correlation analysis was performed to assess the correlation of the levels with CVS occurrence.Binary logistic regression analysis was applied to construct a prediction model with serum ANGPTL8 and Sema 3A as variables.ROC curve was plotted to evaluate the predictive value of the levels for postoperative CVS.Results The serum ANGPTL8 level was significantly higher while that of Sema 3A was obviously lower in the spasm group then the non-spasm group(P＜0.01).Binary logistic regression analysis showed that the levels of serum ANGPTL8 and Sema 3A were independent predictors of postoperative CVS in patients with ruptured IA(OR=1.021,95％CI:1.013-1.029,P=0.000;OR=0.980,95％CI:0.967-0.993,P=0.003).ROC curve analysis indicated that the AUC value,sensitivity and speci-ficity of the two indicators combined together in predicting postoperative CVS was 0.939(95％CI:0.894-0.969),89.33％and 89.38％,respectively,with better predictive efficiency than each indicator alone(P＜0.01).Conclusion Serum ANGPTL8 and Sema 3A levels are closely associat-ed with postoperative CVS in patients with IA rupture,and they can be used as effective indicators for early prediction of postoperative CVS.

Objective To investigate the clinical efficacy of oblique lumbar interbody fusion(OLIF)combined with lateral plate fixation in the treatment of single-level adjacent segment disease(ASDis)following lumbar fusion surgery so as to evaluate the safety and effectiveness of this surgical approach.Methods A retrospective analysis was conducted on 46 patients with single-level ASDis after lumbar fusion surgery from August 2022 to October 2024.Twenty-three patients underwent OLIF combined with lateral plate fixation(OLIF group),while 23 patients received posterior lumbar interbody fusion(PLIF)(PLIF group).The following parameters were compared between the two groups:operative time,intraoperative blood loss,visual analogue scale(VAS)for pain,Oswestry disability index(ODI),disc height(DH),intervertebral foramen height(IFH),and interbody fusion status.Results All the 46 patients successfully completed surgery for single-level ASDis and were followed up for(13.7±1.1)months.The OLIF group had significantly shorter operative time[(70.7±4.6)min vs.(128.6±12.0)min]and less intraoperative blood loss[(58.6±5.7)mL vs.(313.3±47.5)mL]compared to the PLIF group(all P＜0.05).Both groups showed significant improvements in postoperative lumbar VAS and ODI scores at all follow-up time points compared to preoperative values(P＜0.05).The OLIF group exhibited significantly lower lumbar VAS scores at 3 days and 3 months postoperatively than those of the PLIF group(P＜0.05),and there was no statistical difference in VAS scores at the other follow-up time points(P＞0.05).There was no significant difference in postoperative ODI between OLIF group and PLIF group at each time point(P＞0.05).Postoperative DH and IFH were significantly improved in both groups compared to preoperative measurements(P＜0.05).In OLIF group,1 case of transient left thigh numbness resolved with conservative treatment within 2 weeks;1 case of cage subsidence was observed at 1 month postoperatively,achieving fusion without further displacement by 13 months.All the OLIF cases achieved complete fusion(fusion rate:100％).In PLIF group,2 cases of cerebrospinal fluid leakage healed with bed rest,1 case of wound exudation resolved with intensive dressing changes,and 1 case failed to achieve fusion(fusion rate:96％).Conclusion OLIF combined with lateral plate fixation demonstrates satisfactory early clinical outcomes for single-level ASDis after lumbar fusion,with significant advantages in operative efficiency(shorter time plus reduced blood loss)and short-term pain relief.Therefore,it is a safe and effective surgical approach.

Objectives:To investigate the effects of sarcopenia on the clinical efficacy of percutaneous ver-tebral augmentation(PVA)in the treatment of osteoporotic thoracolumbar vertebral compression fracture(OTLVCF).Methods:We retrospectively analyzed the clinical data of 270 patients with OTLVCF who under-went PVA in the Second Affiliated Hospital,Air Force Military Medical University and Honghui Hospital Af-filiated to Xi'an Jiaotong University from January 2020 to December 2022.There were 109 males and 161 females;T10 vertebral fracture in 37 cases,T11 fracture in 52 cases,T12 fracture in 68 cases,L1 fracture in 72 cases,and L2 fracture in 41 cases.The patients were divided into sarcopenia group(52 cases)and non-sarcopenia group(218 cases)according to the diagnostic criteria of the European Working Group on Sar-copenia in Older People(EWGSOP),and using the dominant hand grip strength(＜28.0kg)and the skeletal mus-cle index(SMI)at L3 level(＜45.4cm2/m2)in male and the dominant hand grip strength(＜18.0kg)and SMI at L3 level(＜34.4cm2/m2)in female as the diagnostic thresholds.The general data(gender,age,height,weight,body mass fraction,fracture segment,strength of grasp and skeletal muscle index),operative data(surgical method,operative time,intraoperative blood loss,bone cement injection volume and intraoperative fluoroscopy times),and complications(cement leakage,refracture of injured vertebra,refracture of the adjacent vertebra and distal vertebral refracture)after operation of both groups of patients were collected.The visual analogue scale(VAS)and Oswestry disability index(ODI)were collected before operation and on postoperative 1d,at 1 month,6 months and 1 year postoperatively and compared between the two groups.Results:There was no statistical difference in gender,height,weight,operative method,operative time,blood loss,bone cement injection vol-ume,intraoperative fluoroscopy times,and preoperative VAS score and ODI between the two groups(P＞0.05).The patients in the sarcopenia group were older(80.3±7.9 years vs 75.7±6.8 years,P＜0.05)and had a smaller BMI(24.4±2.2kg/m2 vs 26.2±2.4kg/m2,P＜0.05).The VAS score and ODI of the two groups on ld and,at 1 month,6 months and 1 year after operation were significantly improved compared with those before operation(P＜0.05).At the same time,the VAS score and ODI in the sarcopenia group were significantly higher than those in the non-sarcopenia group on ld and,at 1 month,6 months and 1 year after operation(P＜0.05).In terms of complications,there was no significant difference in the incidence of bone cement leakage between the two groups(9.65％vs 7.34％,P＜0.05).The incidence of re-fracture of injured vertebrae,adjacent vertebrae and distal vertebrae and the total incidence of re-fracture within 1 year after operation in the sarcopenia group were significantly higher than those in the non-sarcopenia group(9.62％vs 2.75％,13.46％vs 5.05％,11.54％vs 4.13％and 33.61％vs 11.93％,P＜0.05).Conclusions:The clinical effects of vertebral augmenta-tion(PVA)in patients with sarcopenia are poorer than in non-sarcopenia OTLVCF patients,with higher verte-bral re-fracture rates within 1 year after operation.

Indole-3-carbinol(I3C),an important anticancer compound found in broccoli,has attracted considerable attention.The rapid extraction and accurate analysis of I3C in the pharmaceutical industry in broccoli is challenging as I3C is unstable at low pH and high temperature.In this study,a rapid,accurate,and low-cost ultrasound-assisted dispersive-filter extraction(UADFE)technique based on poly(deep eutectic solvent)-graphene oxide(PDES-GO)adsorbent was developed for the isolation and analysis of I3C in broccoli for the first time.PDES-GO with multiple adsorption interactions and a fast mass transfer rate was synthesized to accelerate adsorption and desorption.UADFE was developed by combining dispersive solid-phase extraction(DSPE)and filter solid-phase extraction(FSPE)to realize rapid extraction and separation.Based on the above two strategies,the proposed PDES-GO-UADFE method coupled with high-performance liquid chromatography(HPLC)allowed the rapid(15-16 min),accurate(84.3％-96.4％),and low-cost(adsorbent:3.00 mg)analysis of I3C in broccoli and was superior to solid-phase extraction,DSPE,and FSPE methods.The proposed method showed remarkable linearity(r=0.9998;range:0.0840-48.0 μg/g),low limit of quantification(0.0840 μg/g),and high precision(relative standard deviation≤5.6％).Therefore,the PDES-GO-UADFE-HPLC method shows significant potential in the field of pharmaceutical analysis for the separation and analysis of anti-cancer compounds in complex plant samples.

【Objective】 To compare the clinical efficacy of unilateral biportal endoscopic （UBE） and microscopic discectomy in the treatment of lumbar disc herniation （LDH） and to explore the safety and effectiveness of this operation. 【Methods】 A total of 87 LDH patients from July 2018 to July 2021 were analyzed retrospectively， including 42 cases of unilateral biportal endoscopic discectomy and 45 cases of microscopic discectomy. Analysis was based on comparison of perioperative metrics， operation time， and estimated blood loss. Clinical outcomes were evaluated using visual analogue scale （VAS）， Oswestry disability index （ODI） and modified Macnab criterion. 【Results】 All patients were followed up for 13.3±1.18 months. In UBE group， operation time （57.12±6.35） min was shorter than that in the microscope group （62.21±7.09） min and estimated blood loss （29.31±3.62） mL was smaller than that in the microscope group （51.77±8.43） mL， with a significant difference （P<0.05）. The two groups of patients had significantly lower back pain VAS score， leg pain VAS score， and ODI index than those before operation （P<0.05）. The VAS score of lower back pain at 3 days after operation and the ODI index at 1 month after operation were significantly lower in UBE group than in the microscope group （P<0.05）. At other time points， there was no significant difference in lower back pain VAS score， leg pain VAS score or ODI index （P>0.05）. Dural sac tear occurred in 2 cases in UBE group and 3 cases in the microscope group； the incidence was not statistically significant （P>0.05）. Modified MacNab criterion evaluation at the last follow-up showed that 32 cases were excellent in UBE group， 7 cases were good， and 3 cases were fair， with the excellent and good rate of 92.9% （39/42）. The microscope group was excellent in 31 cases， good in 10 cases， and fair in 4 cases， with the excellent and good rate of 91.1% （41/45）. 【Conclusion】 UBE for LDH has a satisfactory short-term clinical efficacy， with the advantages of less trauma， greater efficiency， clear vision， and large operating space. Both UBE and microscopic discectomy can achieve good clinical results in treating LDH， but the former has the advantages of less trauma， high efficiency， and quick postoperative recovery.

Objective: To investigate the impact of coronary lesion calcification on the long-term outcome of patients with coronary heart disease after percutaneous coronary intervention. Methods: In this prospective observational study, a total of 10 119 consecutive patients with coronary heart disease undergoing percutaneous coronary intervention from January 1 to December 31, 2 103 in our hospital were enrolled. The patients were divided into non/mild calcification group (8 268 cases) and moderate/severe calcification group (1 851 cases) according to the angiographic results. The primary endpoint was one-year major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, and target vessel revascularization. Results: The patients were (58.3±10.3) years old, and there were 2 355 females (23.3%). Compared with non/mild calcification group, patients in the moderate/severe calcification group were older ((60.0±10.6) years vs. (57.9±10.2) years, P<0.01), and had higher proportion of female (25.4% (470/1 851) vs. 22.8% (1 885/8 268), P=0.02), debates (33.9% (628/1 851) vs. 29.0% (2 399/8 268), P<0.01), hypertension (68.0% (1 259/1 851) vs. 63.7% (5 264/8 268), P<0.01), coronary artery bypass grafting (4.6% (85/1 851) vs. 3.2% (268/8 268), P<0.01), stroke (12.6% (233/1 851) vs. 10.4% (861/8 268), P=0.01), and renal dysfunction (6.2% (115/1 851) vs. 3.7% (303/8 268), P<0.01). Compared with non/mild calcification group, patients in themoderate/severe calcification group experienced longer procedure time (37 (24, 61) min vs. 27 (17,40) min, P<0.01) and stent length was longer (32 (23,48) mm vs. 27 (18,38) mm, P<0.01), and percent of rotational atherectomy was higher (2.56%(57/2 229) vs. 0.03% (3/11 930), P<0.01). One-year follow-up results showed that MACE (7.5% (139/1 846) vs. 4.9% (402/8 243), P<0.01), all-cause death (1.0% (19/1 846) vs. 0.6% (49/8 243), P=0.04), myocardial infarction (2.2% (41/1 846) vs. 1.4% (114/8 243), P=0.01), and target vessel revascularization (5.0% (92/1 846) vs. 3.2% (266/8 243), P<0.01) were all significantly higher in moderate/severe calcification group than in non/mild group. Multivariate Cox regression analysis showed that moderate/severe calcification was an independent predictor of MACE at one-year after the procedure (HR=1.41, 95%CI 1.16-1.72, P<0.01). Conclusion Moderate/severe calcification in coronary lesion is an independent predictor of long-term poor prognosis in coronary heart disease patients undergoing percutaneous coronary intervention.
