外伤性晶状体脱位合并周边隐匿性视网膜病变的临床特征及预后分析

目的观察分析眼球钝挫伤合并外伤性晶状体脱位患者周边隐匿性视网膜病变的临床特点及预后。 方法本研究纳入2013年1月至2020年1月在柳州市人民医院眼科住院诊断为眼球钝挫伤合并外伤性晶状体脱位，并行23G微创玻璃体切割联合白内障摘除手术的72例（72眼）患者。根据裂隙灯和超声生物显微镜（UBM）检查，将患者分为晶状体不全脱位组和全脱位组，详细记录2组患者的术中周边视网膜病变情况，并分析其临床特征及疗效。 结果眼球钝挫伤合并外伤性晶状体脱位患者中有周边隐匿性视网膜病变的占72.22%，其中晶状体不全脱位组发生率高达80.95%，显著大于晶状体全脱位组的60.00%（P＜0.05）。2组患者的周边隐匿性视网膜病变均以隐匿性视网膜裂孔、变性和出血为最常见。所有患者术后视网膜情况稳定，视力预后较好。 结论眼球钝挫伤合并外伤性晶状体脱位患者常出现周边隐匿性视网膜病变，最常见的是视网膜裂孔、出血、变性。23G微创玻璃体切割联合白内障摘除手术是有效治疗手段，具有创伤小、并发症少的优势。     

Minimally Invasive Treatments for Benign Prostatic Hyperplasia: Systematic Review and Network Meta-Analysis

PurposeTo review and to compare indirectly the outcomes of minimally invasive therapies for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia.Materials and MethodsA literature search via Medline and Cochrane Central databases was completed for randomized control studies published between January 2000 to April 2020 for the following therapies: Rezum, Urolift, Aquablation, and prostatic artery embolization (PAE). Data on the following variables were included: International prostate symptom score (IPSS), maximum urinary flow rate, quality of life, and postvoid residual (PVR). Standard mean differences between treatments were compared through a meta-analysis using transurethral resection of the prostate (TURP) to assess differences in treatment effect.ResultsThere was no significant difference in outcomes between therapies for IPSS at the 3, 6, and 12-month follow ups. Although outcomes for Rezum were only available out to 3 months, there were no consistently significant differences in outcomes when comparing Aquablation versus PAE versus Rezum. TURP PVR was significantly better than Urolift at 3, 6, and 12 months. No significant differences in minor or major adverse events were noted.ConclusionAlthough significant differences in outcomes were limited, Aquablation and PAE were the most durable at 12 months. PAE has been well studied on multiple randomized control trials with minimal adverse events while Aquablation has limited high quality data and has been associated with bleeding-related complications.     

适量运动对心房颤动患者预后的影响:系统综述与Meta分析

目的 分析适量运动对于心房颤动(房颤)患者的运动能力以及远期临床预后的影响。方法 通过检索中国知网,万方,维普,Pubmed,OVID,Cochrane Central Register of Controlled Trials (CENTRAL),web of science数据库,纳入对房颤患者进行适量体育活动干预的临床试验。本研究的主要终点为静息心率,最大心率,6 min步行试验,最大运动功率,全因死亡率以及卒中发生率,用以评估适量运动对房颤患者活动耐力以及预后的影响。结果 本研究共纳入7项试验,2 452例患者,试验组为适量运动干预组,对照组为不活跃组。适量运动并不会显著增加患者的静息心率(MD=-1.68,P=0.70)以及最大心率(RD=9.72,P=0.11)。运动训练可显著提高房颤患者的运动能力,明显增加6 min步行距离(MD=59.07,95%CI=11.70-106.44,P<0.05),并且在一定程度上提高运动功率(MD=17.96,95%CI=-6.30-42.22,P=0.15)。适量运动对房颤患者的远期预后不会造成不良影响,适量运动组对比不活跃组,全因死亡率为15.7% vs 14.2%(RD=0.03,95%CI=-0.18-0.25,P=0.75);卒中发生率5.0% vs 2.9%(RD=0.02,95%CI=-0.06-0.09,P=0.69),两组差异无统计学意义。结论 适量运动可在一定程度上提高房颤患的活动耐力,且不增加卒中以及全因死亡率。     

微创和传统开放后路腰椎椎间融合术治疗腰椎退行性疾病的远期预后

目的探讨微创后路腰椎椎间融合术(MIS-PLIF)和传统开放PLIF对腰椎退行性疾病(LDD)远期疗效及安全性的影响。方法 2011年1月-2014年12月收治LDD患者182例,其中96例采用传统开放PLIF治疗(PLIF组),86例采用MIS-PLIF治疗(MIS-PLIF组)。比较2组腰椎矢状位参数、多裂肌横截面积及萎缩率、融合率、疼痛视觉模拟量表(VAS)评分、日本骨科学会(JOA)评分、Oswestry功能障碍指数(ODI)及术后并发症发生情况,分析多裂肌萎缩率与顽固性腰背痛的相关性。结果 2组术后各随访时间点椎间隙高度恢复值和节段性前凸角恢复值差异均无统计学意义(P > 0.05)。2组术后1年腰椎前凸角恢复值差异无统计学意义(P > 0.05);但术后5年和末次随访时,MIS-PLIF组腰椎前凸角恢复值显著高于PLIF组,差异均有统计学意义(P < 0.05)。MIS-PLIF组术后各随访时间点多裂肌横截面积大于PLIF组,多裂肌萎缩率低于PLIF组,差异均有统计学意义(P < 0.05)。2组术后随访6个月融合率差异无统计学意义(P > 0.05)。2组术后各随访时间点下肢痛VAS评分差异无统计学意义(P > 0.05);MIS-PLIF组术后各随访时间点腰痛VAS评分、JOA评分及ODI均优于PLIF组,差异有统计学意义(P < 0.05)。MIS-PLIF组顽固性腰背痛发生率显著低于PLIF组,差异有统计学意义(P < 0.05)。合并顽固性腰背痛患者多裂肌萎缩率高于未合并顽固性腰背痛的患者,差异有统计学意义(P < 0.05)。结论术后多裂肌萎缩可能是导致顽固性腰背痛的重要原因,相较于传统开放PLIF,MIS-PLIF治疗LDD能够更有效地保持腰椎生理曲度,改善肢体活动功能,降低多裂肌萎缩程度,有助于避免顽固性腰背痛的发生。

Sinensetin attenuates oxygen–glucose deprivation/reperfusion-induced neurotoxicity by MAPK pathway in human cerebral microvascular endothelial cells

Sinensetin is a polymethoxylated flavone with anti-inflammatory and anti-oxidative activities. This work aimed to explore the function and mechanism of sinensetin in oxygen and glucose deprivation/reperfusion (OGD/R)-induced neurotoxicity. The overlapping target genes of cerebral stroke and sinensetin were determined according to GeneCards and ParmMapper tools and were subjected to Gene Ontology (GO) annotations and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Human cerebral microvascular endothelial cells (HCMECs) were stimulated with OGD/R. Neurotoxicity was investigated by Cell Counting Kit-8, lactate dehydrogenase (LDH) release, reactive oxygen species (ROS) level, qRT-PCR, and TUNEL analysis. The proteins (p38, JNK, and ERK) in mitogen-activated protein kinase (MAPK) signaling were measured using Western blotting. Total of 50 overlapping target genes of cerebral stroke and sinensetin were predicted. Pathway analysis showed they might be involved in the MAPK pathway. Sinensetin attenuated OGD/R-induced neurotoxicity by mitigating viability reduction, LDH release, ROS generation, inflammatory response, and apoptosis in HCMECs. Sinensetin weakened OGD/R-induced activation of the MAPK pathway via decreasing the phosphorylation of p38, JNK, and ERK. The pathway inhibitors mitigated the activation of the MAPK signaling, and sinensetin exacerbated this effect. The inhibitors reversed OGD/R-induced neurotoxicity in HCMECs, and sinensetin contributed to this role. Overall, sinensetin prevents OGD/R-induced neurotoxicity through decreasing the activation of MAPK pathway.
