Efficacy and safety of cold snare polypectomy for sessile serrated polyps ≥ 10 mm: A systematic review and meta-analysis

BackgroundCold snare polypectomy (CSP) is a promising technique for the removal of sessile serrated polyps (SSPs) ≥ 10 mm. However, the efficacy and safety of this technique remain undetermined.AimsWe aimed to comprehensively evaluate the efficacy and safety of CSP for SSPs ≥ 10 mm.MethodsPubMed, EMBASE, Web of Science and Cochrane Library were searched up to January 2021.ResultsA total of 10 studies consisting of 1727 SSPs (range, 10–40 mm) from 1021 patients were included. The overall rates of technical success, adverse events (AEs) and residual SSPs were 100%, 0.7% and 2.9%, respectively. Subgroup analysis showed that the rates of technical success and AEs were comparable between CSP and cold endoscopic mucosal resection (EMR) (99.9% vs. 100% and 1.3% vs. 0.5%, respectively), between the proximal and distal colon (100% vs. 99.9% and 0.3% vs. 0, respectively), and between polyps of 10–19 mm and ≥20 mm (99.8% vs. 100% and 0.9% vs. 0, respectively). However, subgroup analysis showed that the rate of residual SSPs was slightly lower in CSP compared with cold EMR (1.3% vs. 3.9%), as well as in polyps of 10–19 mm compared with those ≥20 mm (3.1% vs. 4.7%).ConclusionCSP was an effective and safe technique for removing SSPs ≥ 10 mm.     

利用微信平台延续性护理对老年腰椎间盘突出症术后患者康复及生活质量的影响

目的探讨微信平台延续性护理对老年腰椎间盘突出症术后患者康复及生活质量的影响。方法选取2015年6月—2018年5月在郑州市骨科医院接受手术治疗的老年腰椎间盘突出症患者96例进行研究。对照组行常规延续性护理,观察组行微信平台延续性护理。对比两组康复效果、治疗依从性及生活质量。计数资料采用卡方检验分析,计量资料采用t检验分析。结果观察组有效率为95.83%,明显高于对照组的81.25%。观察组总依从率为91.67%,明显高于对照组的77.08%。干预前两组生活质量量表得分相当,治疗后两组生活质量均有明显改善,但观察组改善程度更为明显。结论微信平台延续性护理相比传统延续性护理可明显提高老年腰椎间盘突出症患者康复效果、提高治疗依从性和改善生活质量。     

VAC结合游离植皮治疗儿童大面积皮肤缺损疗效观察及对患儿生活质量的影响

目的:探讨负压创面治疗技术(Vacuum assisted closure,VAC)结合游离植皮治疗儿童大面积皮肤缺损疗效及对患儿生活质量的影响。方法:选取2015年2月-2019年2月笔者医院收治的60例大面积皮肤缺损患儿作为研究对象,按照随机数表法分为干预组和对照组,每组30例。对照组采用游离植皮术治疗,干预组在对照组的基础上结合VAC治疗,以皮片成活时间、皮片成活率、换药次数及住院天数评估疗效,以长海痛尺分级法评估患儿疼痛等级,以抑郁自评量表(Self-rating depression scale,SDS)、焦虑自评量表(Self-rating anxiety scale,SAS)评估患儿心理状态,以术后不良反应发生率评估患儿预后情况,以自制生活质量表评估患儿生活质量水平。结果:干预组患儿皮片成活时间、换药次数与住院天数均小于对照组,差异有统计学意义(P<0.05)。干预组患儿皮片成活率为93.33%高于对照组的76.67%,差异有统计学意义(P<0.05)。干预组治疗后疼痛感、SDS与SAS评分低于治疗前,且低于对照组,差异有统计学意义(P<0.05)。干预组患儿术后不良反应发生率为6.67%显著低于对照组23.33%,差异有统计学意义(P<0.05)。两组治疗前活动能力、心理健康及社交能力均低于治疗后,干预组治疗后活动能力、心理健康及社交能力均高于对照组(P<0.05)。结论:VAC结合游离植皮治疗儿童大面积皮肤缺损疗效显著,能有效降低患儿生理疼痛与心理焦虑,减少伤口感染等不良反应的发生,提高患儿生活质量,具有推广价值。

Clinical Study on CT-guided Modified Akupotomye in the Treatment of Lumbar Nerve Posterior Branch Compression

Objective: To observe the clinical effect of modified akupotomye closed lysis under CT guidance on compression of posterior lumbar nerve branch.Methods: Patients were diagnosed by HRCT 3-D reconstruction combined with clinical symptoms and signs.After HRCT three-dimensional reconstruction combined with clinical symptoms and signs, the patients were confirmed as posterior lumbar nerve compression.After CT accurate surface positioning, CT-guided modified akupotomye was used for closed lysis of the posterior lumbar nerve branch.Oswestry Dysfunction Index Questionnaire(ODI) was used for quantitative scoring, 7 days before and after treatment and 6 months after treatment.Results: In 62 cases, 20 cases were cured, with 25 cases markedly effective, 11 cases effective, and 36 cases ineffective.The total effective rate was 90.3%.ODI score: Self-paired t test 7 days before after treatment, P < 0.01;Before treatment and 6 months after treatment, self-paired t test(P < 0.01);Self-paired t-test was performed 7 days after treatment and 6 months after treatment(P > 0.05).Conclusion: With CT precise positioning, the modified akupotomye can be used to do closed lysis, to relieve the adhesion and compression, so that the low back pain can be relieved, with good clinical.The akupotomye closed lysis, combined with modern imaging technology has not only achieved good clinical effect, but also can improve the accuracy, safety and scientificity of akupotomye treatment.     

颞下颌关节强直动物模型中最大张口度与强直严重程度关系研究

目的　研究主、被动最大张口度（AMMO、PMMO）与颞下颌关节强直严重程度的关系。方法　选取28只健康雄性绵羊随机分为实验组和对照组，每组各14只。实验组绵羊双侧颞下颌关节模拟髁突矢状骨折，其中左侧翼外肌被切断以阻断其功能；对照组绵羊未进行手术。于术前及术后12、24周对所有绵羊体重、AMMO、PMMO、颞下颌关节形态学特点进行测量评估。结果　实验组只有右侧保留翼外肌功能的颞下颌关节发生了骨强直。术后12、24周，实验组绵羊AMMO、PMMO、极限距离均显著低于对照组，差异均有统计学意义（均P < 0.05）。实验组绵羊AMMO和PMMO与骨融合区宽度、长度、面积及钙化程度均呈负相关（均P < 0.05），其中骨融合区面积为主要影响因素（术后12、24周相关系数r分别为-0.94、-0.95）。结论　颞下颌关节强直动物模型中阻断翼外肌功能可阻止骨强直的发生；对于早期髁突矢状骨折，可通过牙合垫或牙合板进行张口训练，进而阻断翼外肌功能。当颞下颌关节发生骨强直时，骨融合区面积越大，张口受限越明显。
