Transvaginal sonography and rectal endoscopic sonography for the assessment of pelvic endometriosis: a preliminary comparison

BACKGROUND: Endometriosis and possible rectal involvement are difficult to assess by physical examination. Previous studies have shown the diagnostic value of magnetic resonance imaging and rectal endoscopic sonography (RES) in this setting, but not that of transvaginal sonography (TVS). The aims of this study were to compare the accuracy of TVS and RES for the diagnosis of pelvic endometriosis, and to compare the results with histological findings. PATIENTS AND METHODS: In a prospective study, 30 consecutive patients referred with clinical signs of endometriosis underwent TVS and RES; the images were interpreted blindly with regard to physical findings. RESULTS: Endometriosis was confirmed histologically in 28 (93%) of the 30 patients. Endometriomas were also present in 67% of cases. For the diagnosis of uterosacral endometriosis, the sensitivity, specificity, and positive and negative predictive values of TVS and RES were 75 and 75%, 83 and 67, 95 and 90%, and 45 and 40% respectively. For the diagnosis of rectosigmoid endometriosis, the sensitivity, specificity, and positive and negative predictive values of TVS and RES were 95 and 82%, 100 and 88%, 100 and 95%, and 89 and 64% respectively. CONCLUSION: Despite the large proportion of our patients who had intestinal endometriosis, representing a possible source of bias, our results suggest that TVS is as efficient as RES for detecting posterior pelvic endometriosis and should therefore be used as the first-line examination.     

川芎嗪对急性心肌梗死血运重建后"心肌无复流"患者心肌组织灌注的影响

目的 观察川芎嗪对急性心肌梗死（AMI）患者梗死相关血管（mA）再通后心肌无复流（No．reflow，NR）现象的疗效。方法 首次急性sr段抬高心肌梗死（STEMI）患者，急诊经皮经腔冠状动脉介入（PCI）后，经单光子发射型计算机断层显像（SPECT）诊断为心肌NR者，随机分为治疗组（40例）和对照组（42例）。对照组接受常规治疗，治疗组在常规治疗基础上静脉给予川芎嗪注射液。分别于24h内（4—24h）及15d后（15—28d）复查SPECT，观察左室心肌灌注缺损积分（myocardium peffusion defect score，MPDS），左室射血分数（LVEF）、左室舒张末期容积（LVEDV）和左室收缩末期容积（LVESV）。结果 24h内及15d后，治疗组的MPDS均较PCI后即刻减低，其减低幅度均显著大于对照组（均P〈0．05）；两组的LVESV和LVEDV均呈增加趋势，但治疗组LVESV和LVEDV的增加幅度显著低于对照组（均P〈0．05）；15d后治疗组SPECT心肌NR的发生率显著低于对照组。结论 川芎嗪可显著改善心肌组织灌注，减轻心肌NR现象，从而缩小心肌坏死范围。抑制心室重构。     

经单侧穿刺椎体后凸成形术治疗侧方椎体压缩性骨折

目的研究经单侧椎弓根穿刺椎体后凸成形术治疗侧方骨质疏松性椎体压缩骨折(osteoporotic vertebral compression fractures,OVCF)的疗效。方法选择我院2009年10月~2011年10月收治的30例侧方OVCF患者,随机行凹侧或双侧球囊撑开椎体后凸成形术治疗,分别在术后1、6、12个月进行随访,对椎体高度恢复、脊柱后凸、侧凸Cobb角及并发症进行评价。结果术后1、6、12个月的随访结果比较发现,凹侧撑开及双侧撑开组患者椎体高度均较术前明显恢复(P0.05),脊柱后凸、侧凸Cobb角均较术前明显纠正(P0.05)。术后定期随访无丢失。凹侧撑开组与双侧撑开组之间比较,上述指标差异无统计学意义(P0.05)。结论经凹侧球囊撑开椎体成形治疗侧方OVCF,与双侧撑开相比疗效相当,可简化手术、缩短手术时间、减小创伤、减少费用,是治疗侧方OVCF的有效方式。     

冠状动脉内溶栓联合 PCI 治疗对急性心肌梗死患者的影响

〔摘 要〕 目的：观察冠状动脉内溶栓联合经皮冠状动脉介入（PCI）治疗对急性心肌梗死（AMI）患者血清小分子核糖 核酸（miRNA）序列与临床指标的影响。 方法：选取 2020 年 1 月至 2023 年 1 月鹤壁市人民医院收治的 74 例 AMI 患者资料, 根据治疗方案不同分为对照组和观察组,各 37 例。对照组单用 PCI 治疗,观察组采用冠状动脉内溶栓联合 PCI 治疗。比较 两组患者治疗前后血流分级情况、血清 miRNA 序列、心功能指标以及不良反应发生情况。 结果：治疗后,观察组患者急性 心肌梗死溶栓评分（TIMI）血流分级优于对照组,差异具有统计学意义（P ＜ 0.05）。治疗后,观察组患者 miRNA–210、 miRNA–146a 均低于对照组,miRNA–214、miRNA–155 均高于对照组,差异具有统计学意义（P ＜ 0.05）。治疗后,观察组 患者左心室舒张末期容积指数（LVEDVI）、左心室收缩末期容积指数（LVESVI）均低于对照组,左心室射血分数（LVEF） 水平高于对照组,差异具有统计学意义（P ＜ 0.05）。两组患者不良反应发生率比较,差异无统计学意义（P ＞ 0.05）。 结论：冠状动脉内溶栓联合 PCI 治疗 AMI 能够进一步调节 miRNA 序列水平,改善患者血流分级及心功能。     

Is ‘Omega Sign’ anatomical endoscopic enucleation of the prostate technique reproducible?

We aimed to evaluate the learning curve of the surgically standardised ‘Omega Sign’ anatomical endoscopic enucleation (AEEP) of the prostate surgery technique for junior surgeons. This study is a retrospective comparison of cases that underwent AEEP by a mentor surgeon and three junior surgeons who have completed their learning curve. A video-based laser enucleation of the prostate assessment tool (LEAT) composed of 8 steps of the technique was used to assess a senior surgeon and junior surgeons’ surgical compatibility and consistency. The surgeon who defined Omega Sign technique was determined as group 1, and cases by three junior surgeons were identified as group 2. The end points were to assess the reproducibility and repeatability and operative post-operative outcomes of the technique. 55 patients’ videos were rated by five experienced endourologists. There was no significant difference in LEAT scores between the groups among all steps. The most symmetry was found in the 1st and 3rd steps. Inter-rater consistency was also high for each step, with no statistically significant difference between the evaluators. The standardised anatomical ‘Omega Sign’ technique is reproducible for the junior surgeons. The operative steps can be performed with high consistency, and the functional and perioperative outcomes are comparable with the senior surgeon.     

经椎间孔入路全内镜下腰椎椎体间融合技术研究进展

经椎间孔入路全内镜下腰椎椎体间融合术（full endoscopic transforaminal lumbar interbody fusion）近年来在微创脊柱外科领域获得广泛应用,本文简要介绍该术式的发展历史、技术要点、适应证、疗效以及并发症。笔者认为经椎间孔入路全内镜下腰椎椎体间融合术具有与传统手术同样的临床效果,并且能够有效减少组织损伤和术中出血、降低术后腰背痛的发生率、缩短术后下床活动时间及平均住院日,但仍需完善远期随访,以进一步评估该术式的有效性和安全性。     

年轻女性乳腺癌外科治疗焦点问题及对策

年轻乳腺癌病人预后较差,与侵袭性生物学特征密切相关,是临床治疗的一大难点。年轻女性乳腺癌病人的外科手术抉择需要综合权衡肿瘤生物学特征、病人的自身需求、社会家庭支持因素等各个方面。对于早期肿瘤应当积极开展保乳手术,对于临床分期较晚的肿瘤,建议参照分子分型积极开展新辅助治疗,或者实施合适的乳房重建技术。临床医师应当为病人提供更加充分的信息与高级别的循证医学证据,鼓励病人积极参与外科手术决策的制定。
