钉棒椎弓根系统内固定治疗胸腰段脊椎骨折伴截瘫患者的术后护理

对24例胸腰段脊椎骨折伴截瘫患者实施钉棒椎弓根系统内固定治疗。结果患者均顺利完成手术,神经功能均较术前恢复1～2级。提出术后做好呼吸道、切口引流管、疼痛护理及并发症的预防和康复锻炼,是提高手术效果,促进患者康复的重要保证。     

刺鼠信号蛋白对自体移植皮片中酪氨酸酶的活性影响

目的 检测刺鼠信号蛋白对自体移植皮片中酪氨酸酶的活性影响,进一步认识自体移植皮片过度色素沉着的原因。方法 建立过度色素沉着的自体移植皮片的动物模型；利用免疫组织化学方法分别检测刺鼠信号蛋白作用前后自体移植皮片中酪氨酸酶的表达,并与对照治疗组及正常皮肤相比较。结果 酪氨酸酶的表达定位于表皮基底部黑色素细胞的胞浆,在大部分组织中呈阳性表达,经刺鼠信号蛋白作用后酪氨酸酶在自体移植皮片中的表达明显减少,与在其他各对照组中的表达差异有极显著意义（P＜0.01）。结论 刺鼠信号蛋白在自体移植皮片中能竞争性拮抗α-MSH的黑色素合成,使皮片着色能力降低,从而证明皮片移植后表皮细胞中α-MSH的表达上调是皮片呈过度色素沉着的重要原因。     

中西医结合治疗小儿急性肾小球肾炎临床观察

急性肾小球肾炎为临床常见病，多发于少年儿童，男性多见。西医除对症处理外，无特效药物，中药治疗本病可明显缩短病程。笔者自2003年1月至2006年1月用清热利湿解毒汤治疗急性肾小球肾炎60例取得确切疗效，现报道如下。     

腹腔镜肝切除术患者的护理

笔者报道腹腔镜肝切除术患者的护理。术前进行心理护理和呼吸训练；术后注意早期活动，加强腹腔镜CO2气腹后的观察、护理，做好皮下气肿、胆漏、出血、高碳酸血症和下肢静脉血栓等术后并发症的观察及护理。认为周到细致的护理是手术成功的重要保证。     

CT导向下125I种子源植入治疗恶性肿瘤

目的:探讨CT导向下125I种子源植入治疗恶性肿瘤的安全性及临床疗效。方法:11例患者14个病灶行CT导向下125I种子源植入,其中原发肿瘤5例,转移瘤6例(9个病灶)。根据治疗计划系统(TPS)计算布源,在CT导向下将18.5~29.6MBq活度的125I种子源相隔1.0~1.5cm多层面植入肿瘤内。术后1~10个月复查CT观察种子源在瘤体内的分布、疗效及有无并发症。结果:随诊CT复查,14个病灶完全缓解(CR)5个;明显缓解(OR)7个;部分缓解(PR)2个;无效(P)0。治疗前后病灶平均大小分别为4.23cm和2.07cm(t=5.018,P<0.01)。未见急性并发症和治疗相关的放射损伤。结论:CT导向下125I种子源植入治疗恶性肿瘤是一种安全、有效的方法,近期疗效肯定。     

Liver and lung resection for colorectal metastasis

Aim: To examine the survival benefit of liver and lung resection for colorectal metastasis and the potential prognostic factors that affect patient survival. Methods: All patients who had resection of lung or liver metastasis for colorectal metastasis in Queen Elizabeth Hospital, Hong Kong from 1995 to 2004 were retrospectively reviewed. The overall and disease‐free survival was analysed, in particularly between liver and lung metastasis. All factors that may have affected the survival were entered into Cox's proportional hazards regression model to identify significant variables associated with survival. Results: At 5 years, the overall survival of patients who had resection of lung and liver metastasis was 44% and 38%, respectively; the disease‐free survival was 26% and 24%, respectively. Overall and disease‐free survival of patients with resection of lung metastasis was comparable to those with resection of liver metastasis. The differentiations of primary tumour and time to metastasis were shown to be significant prognostic factors influencing overall survival. Those patients with systemic chemotherapy after resection of colorectal metastasis demonstrated a significantly higher probability of overall survival. Conclusion: Resection of lung and liver metastases from colorectal origin was safe and both procedures improved survival. The use of chemotherapy after resection of metastasis significantly improved the overall survival.     

后腹腔镜下离断式肾盂成形术

目的探讨后腹腔镜下肾盂成形术的临床疗效. 方法腹腔镜下通过后腹腔途径对9例肾盂输尿管连接部狭窄行离断式肾盂成形术并对技术进行改进. 结果 9例手术均获成功,手术时间110～240 min,平均160 min.术中出血量30～80 ml,平均50 ml.术后住院8～18 d,平均11.2 d.术后并发症:皮下气肿(合并阴囊气肿)1例,漏尿2例.术后1～10个月B超示术侧肾盂无积水5例,轻度积水2例,中度积水2例.3例术后5个月IVU显示吻合口通畅. 结论后腹腔镜肾盂成形术微创、效果好,值得推广.     

试论七情发生和脑主神明与抑郁症病机证治的关系

抑郁症是一组以抑郁心境自我体验为中心的临床症状群或状态.中医多将其归在郁证之类,对其理论解释的重点多是在心主神明论指导下的以五脏为中心的肝,临床治疗亦多遵疏肝解郁这一基本大法,并取得了一定成效.
