二补助育汤对胚胎着床障碍小鼠子宫血管生成相关因子表达的影响

目的：探讨二补助育汤对胚胎着床障碍模型小鼠子宫内膜形态及血管生成素-1（Ang-1）mRNA、血管内皮生长因子（VEGF）mRNA的表达和定位的影响。方法：24只ICR雌性小鼠随机分为空白组、模型组、戊酸雌二醇组、二补助育汤组，每组6只，用米非司酮建立胚胎着床障碍动物模型，各组给予相应药物灌胃，妊娠第5天处死小鼠后，检测各组妊娠率、平均着床位点数、子宫内膜Ang-1和VEGF mRNA表达量及其蛋白定位。结果：模型组小鼠平均胚胎着床位点数、Ang-1 mRNA、VEGF mRNA表达量明显低于空白组（均P<0.05）；与模型组比较，二补助育汤组平均胚胎着床位点数、Ang-1 mRNA、VEGF mRNA表达量显著提高（均P<0.05）。结论：二补助育汤可提高子宫内膜Ang-1和VEGF蛋白表达量，促进子宫内膜血管生成，从而提高子宫内膜容受性。     

Vascular anatomy and surgical approach in oblique lateral interbody fusion at lumbosacral transitional vertebrae

BackgroundOblique lateral interbody fusion (OLIF) at lumbosacral junction is typically performed on the central window between the bifurcations of iliac vessels. However, the central window of lumbosacral transitional vertebrae (LSTVs) is usually obstructed by the iliocaval venous structures. We aimed to describe the vascular anatomy and surgical approach in OLIF at LSTVs compared with those in OLIF at typical L5-S1 junction.MethodsSixty-eight consecutive patients who underwent OLIF at lumbosacral junction were included. Of these, 31 patients had LSTVs and 37 patients had typical L5-S1 junction. The position of the iliocaval junction and the configuration of the left common iliac vein were compared using the preoperative CT and MR images of the lumbar spine. The surgical approach and intraoperative vascular findings were analyzed.ResultsAlmost 70% of LSTVs had the iliocaval junction at low or very low position. Mobilization of left common iliac vein for central window was potentially difficult in almost 74% of OLIF at LSTVs while it was not required or was potentially easy in almost 80% of OLIF at typical L5-S1. Vascular injury was identified in 2 (6.5%) patients with OLIF at LSTVs and in 3 (8.1%) patients with OLIF at typical L5-S1 junction (P = 0.904).ConclusionsIn our series, OLIF at LSTVs was performed through lateral window in 93.5% of the cases. Preoperative evaluation of the iliocaval junction using CT/MR of lumbar spine was reliable and valid in the determination of OLIF approach at lumbosacral junction.     

三镜联合治疗胆总管结石患者基于决策辅助的术前教育

目的探讨基于决策辅助的术前教育在三镜联合治疗胆囊并胆总管结石患者加速康复外科中的应用效果。方法选取行三镜联合治疗胆囊并胆总管结石患者60例,采用随机数字表法将患者分成干预组和对照组各30例。对照组采取常规术前教育,干预组采取基于决策辅助的术前教育。结果干预结束时,干预组决策参与满意度得分和术后治疗依从性得分显著高于对照组,干预组术后首次排气时间、引流时间和住院时间显著短于对照组(P0.05,P0.01)。结论基于决策辅助的术前教育有助于提高三镜联合治疗胆囊并胆总管结石患者的决策参与满意度、术后治疗依从性,有利于促进患者术后恢复。     

急性胆源性胰腺炎合并急性重症胆管炎处理策略

急性胆源性胰腺炎合并急性重症胆管炎病情凶险，病死率高。早期诊断，在内科治疗的同时，积极手术，合理选择内镜胆道引流、经皮经肝胆道引流、开放胆总管探查等治疗策略，以期阻止或延缓病情进展，降低并发症发生率及病死率。     

Factors Affecting Recurrent Deep Vein Thrombosis after Pharmacomechanical Thrombolysis and Left Iliac Vein Stent Placement in Patients with Iliac Vein Compression Syndrome

PurposeThis study evaluated the factors affecting contralateral and ipsilateral recurrent deep vein thrombosis (DVT) after iliac vein stent placement in patients with iliac vein compression syndrome (IVCS).Materials and MethodsData from 130 patients (95 female patients) who underwent catheter-directed thrombolysis and stent placement for IVCS with left lower leg thrombosis at a single institution were retrospectively analyzed. Mean patient age was 69.0 ± 14.0 years old. Median follow-up was 14 months (range, 3–164 months). Anticoagulation therapy was prescribed for 6 months, followed by lifelong antiplatelet therapy. Multivariate logistic regression analysis was performed to evaluate the factors affecting the development of contralateral and ipsilateral recurrent DVT.ResultsSeven patients (5.4%) developed contralateral DVT (median, 26 months; range, 2–61 months), and 11 patients (8.5%) developed ipsilateral DVT (median, 1 month; range, 0–53 months). Stent location (odds ratio [OR], 11.564; 95% confidence interval [CI], 1.159–115.417) and in-stent thrombosis during follow-up (OR, 15.142; 95% CI, 1.406–163.119) were predictors of recurrent contralateral DVT. Thrombophilia (OR, 47.560; 95% CI, 2.369–954.711), remaining inferior vena cava filter (OR, 30.552; 95% CI, 3.495–267.122), and in-stent thrombosis during follow-up (OR, 82.057; 95% CI, 2.915–2309.848) were predictors of ipsilateral DVT.ConclusionsContralateral DVT occurs late and is associated with extension of the iliac vein stent to the inferior vena cava and in-stent thrombosis. Ipsilateral DVT occurs relatively early and is associated with thrombophilia, remaining inferior vena cava filter, and in-stent thrombosis.     

复合手术治疗复杂硬脑膜动静脉瘘近中期效果

目的探讨复合手术治疗复杂硬脑膜动静脉瘘(DAVF)的近中期临床效果。方法回顾性分析2017年1月至2018年12月南方医科大学南方医院收治的20例DAVF患者临床资料,其中符合纳入标准的8例接受复合手术治疗。术后定期随访复查头颅CT/MRI和DSA评估瘘口闭合情况,评估神经功能、改良Rankin量表(mRS)评分变化。结果术中即刻造影显示瘘口完全闭塞7例(7/8),近完全闭塞1例(1/8)。术后2周1例因突发肺栓塞死亡。随访3~24个月,复查CT/MRI和DSA显示7例恢复良好,均无新发神经功能障碍,既往严重临床症状得到改善,mRS评分下降至2~3分。结论复合手术治疗静脉窦闭塞或多"共同通道"的复杂DAVF,可提供明确的治疗入路,通过一次全面手术使瘘口彻底永久性闭合,术后近中期临床预后较好。
