肺切除术影响围手术期右心功能

Objective To investigate the changes of perioperative right ventricular function after pulmonary resction. Methods 45 cases of pulmonary resection were divided into four groups.Group Ⅰwas wedge resection(n = 10), GroupⅡ was lobectomy(n = 19), Group Ⅲ was double lobectomy(n=7)and Group Ⅳ was pneumonectomy(n=9). The changes of CVP, PAMP, PEP/ET, Sa, VTIs, RVSP, Ea/Aa, and Tel were evaluated by traditional ultrasonic and tissue Doppler ultrasonic techniques at different time inter- vals (pre-operation, 5-7 days orland 1 month post-operation), Results Compared with the pre-operation CVP, the indexes of all groups have no significant changes post-operatively. Wedge resection didn' t obviously influence right cardiac after load and systolic function/diastolic function. No evidet changes detected in Tei pre-and post-operatively. However, the indexes (PAMP, RVSP and PEP/ET ratio) reflecting right cardiac afterload evidently increased at post-pneumonectomy or lobectomy group5- 7 days post-opera- tive. All these reflect the decrease of Tei, which was more obvious in pneumonectomy than in lobectomy group. Right cardiac after- load, systolic/diastolic function and Tel index recovered to pre-operative level 1 month post-operation in single lobectomy group. But the above indicators, especially the Tel, were still high in double lobectomy and pmeunonectomy groups 1 morth post-operation.Tei index is positively correlated with PAMP and is weakly correlated with PET/ET ratio and Ea/Aa ratio. Conclusion Pulmonary wedge resection doesn't evidently influence right cardiac function. However, right cardiac diastolic function evidently decreases temporarily at lobectomy group. The systolic function and diastolic funetions decrease after double-lobectomy and pneumonectomy and it's more evident in pneumonectomy group. Though the right cardiac afterloads of lobectomy, double lobectomy and pneumonectomy groupa all increase significantly post-operativlye, only the former recover to pre-operative level 1 month after surgery.

胃癌是我国常见的恶性肿瘤，根治术后仍有部分复发和死亡病例，淋巴结转移是主要的原因之一，是影响胃癌病人预后的重要因素。胃癌现代外科治疗的进步，提高了手术切除率、根治切除率及5年生存率，降低了手术死亡率及术后并发症发生率。胃癌现代外科治疗从一般的胃大部切除术进入以清除淋巴结为目的的根治术；从解剖学为基础     

半球脑出血微创清除术后脑水肿的观察

目的 探讨半球脑出血微创清除术后脑水肿的CT和临床的变化。方法 对75例患者术后临床和CT进行不同时间观察。结果 术后一周内86.6％的患者意识障碍和瘫痪减轻，第二周、第三周病情进一步好转，有部分病人因脱水剂减量致头痛、呕吐、瘫痪和意识障碍加重，经脱水调整等治疗后好转，病情的完全稳定需4周后。CT检查：中线结构移位术后第一周平均6mm，第二周9mm，第三周6mm，第四周2mm，4周后大部分中线恢复正常。结论 微创血肿清除术可缓解局部压力，但脑水肿过程不可避免，大多持续2周～3周后好转、需积极治疗。

超声生物显微镜在眼前节的临床应用

超声生物显微镜(UltrasoundBiomicroscopy)是超高频率的超声医学诊断仪,现在应用的频率是50MHz ,分辨率50μm ,组织穿透深度4mm。眼前节包括全部角膜、虹膜、睫状体、前房、后房、晶状体悬韧带、房角以及部分晶状体、周边玻璃体视网膜,眼外肌附着点部和结膜等。它为活体眼前节结构提供实时、非侵入性、无干扰、可动静态定性、定量观测功能。UBM能够显示后房组织结构,在闭角型青光眼、青光眼手术、色素剥脱综合征、睫状体疾病等有较大的临床意义[1]。1UBM的成像原理UBM是由50兆赫换能器与临床B超仪结合而成。超声生物显微镜的工作原理与传统的B型超声仪基本相同,但为达到在高频率下实时B型模式成像的目的,应用了新技术:高频换能器、高频信号处理、精确的移动控制。UBM采用扇形扫描方式,由探头发出超声脉冲扫描标本,由于标本的声阻抗不同,反向散射的超声波被同样的探头接收,通过复杂的信号传递、放大、处理系统形成影像。UBM产生的影像是运用数字转化技术(digitalconversiontechnology)而产生的计算机控制下的影像,用这种技术能很容易地作某些形态学评估,譬如距离和角度的测量。现应用频率50...     

电子阴道镜在宫颈癌前病变诊断中的应用

目的：探讨电子阴道镜在宫颈癌前病变诊断中的临床应用价值，方法：对妇科门诊的597例患者行阴道镜检查，同时做病理活检。结果：正常阴道镜图像469例，病理结果慢性宫颈炎417例，宫颈上皮内瘤样变(CIN)Ⅰ级52例；异常阴道镜图像128例，病理结果慢性宫颈炎17例，宫颈(CIN)Ⅰ级14例，CINⅡ级72例，CINⅢ级19例，原位癌4例，浸润癌2例。结论：电子阴道镜在宫颈癌前病变的诊断中有较大价值，其操作灵活方便，其图像管理更有利于宫颈癌前病变的动态观察和随访。
