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。     

HBV两种感染模式患者血清CG、β2—MG测定的意义

目的探讨血清ALT、CG、β2-MG浓度变化对HBsAg、HBeAg、HBcAb阳性(A组)及HBsAg、HBeAb、HB鄄cAb阳性(B组)的乙型病毒性肝炎的监测价值。方法将180例HBV感染者按乙型病毒性肝炎感染模式分为A组(94例)和B组(86例)二组,同时选取健康人43例作为对照组。测定血清ALT、CG、β2-MG浓度,采用ELISA法检测HBV标记物;酶法测定ALT;放射免疫法测定CG、β2-MG。结果①与健康对照组比较,A组和B组ALT、CG、β2-MG均有显著性差异(P﹤0.01);②A组ALT、CG、β2-MG与B组比较有显著性差异(P﹤0.01)。结论测定血清CG、β2-MG可较早期、较全面的反映乙肝患者肝脏损伤程度,在临床应用中是具有较强实用性的血清学指标。

严重脊柱侧凸矫形患者围术期的舒适护理

对28例严重脊柱侧凸患者行矫形手术，结果手术均获成功，松解术后1周行后路矫形内固定加植骨融合术，术后Cobb角平均为40．8°，侧弯矫正率平均为52．0％。术后随访6～30个月，均无并发症发生。提出在做好脊柱侧凸矫形手术常规护理的同时，加强患者心理、体位、呼吸、镇痛、排便等方面的舒适护理，可增强患者舒适感，为手术获得成功和患者顺利康复提供有力保障。     

Lithium and haloperidol differentially alter the dynorphin A (1-8) and enkephalin levels in the neurointermediate lobe of rat pituitary

Repeated administration of the antimanic drug lithium (4 mEq/kg/day for 2, 4 or 6 days, i.p.) to rats produced a progressive decline and eventual depletion of dynorphin-A (1-8) (DYN) concentration whereas Met5-enkephalin (ENK) was only marginally decreased in the neurointermediate lobe of the pituitary (NIL). Administration of a neuroleptic haloperidol neither affected ENK and DYN levels nor influenced lithium-induced changes. The study reveals that lithium produces a preferential perturbation in the dynorphin system relative to the enkephalin system. These results taken together with other evidence, indicate that dynorphin is possibly coreleased with vasopressin following lithium administration and provide a pharmacological support to the previously described colocalization and corelease of these endogenous peptides in the NIL.     

沙培林增强人腹腔巨噬细胞抗癌免疫功能的研究

目的:探讨腹腔内注射沙培林增强人腹腔抗癌免疫功能的机制。方法:72例早中期胃肠道肿瘤患者术前48h和24h腹腔内分别注射生理盐水和5KE的沙培林,术中采集腹腔内巨噬细胞,计数并测定乳酸脱氢酶(LDH)和酸性磷酸酶(ACP)的活性,巨噬细胞吞噬活力,一氧化氮(NO)的分泌以及对人胃癌MKN1细胞的细胞毒性进行分析。同时采集大网膜,对大网膜乳斑的数量和面积进行观察。结果:沙培林显著增加腹腔巨噬细胞(PMΦ)的数量和NO的分泌,增强LDH和ACP的活性,吞噬活力,以及抗癌细胞毒性,也显著增加了大网膜乳斑的数量和面积。结论:腹腔内注射沙培林可显著增加人大网膜乳斑的数量和面积,并因此增加PMΦ的数量,增强PMΦ的活性。因而增强了腹腔巨噬细胞的免疫功能。     

中药高臀位灌肠治疗慢性肾功能衰竭疗效观察

目的 观察中药高臀位灌肠治疗慢性肾功能衰竭(chronic renal failure,CRF)的临床疗效.方法 将100例CRF患者随机分为两组,治疗组70例采用中药高臀化灌肠治疗,对照组30例口服活性炭治疗.结果 治疗组总有效率为88.6%,对照组总有效率为50.0%.结论 中药高臀位灌肠治疗CRF有效.     

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.     

妊娠高血压综合征尿蛋白的丢失对新生儿出生体重的影响

目的: 几乎没有研究报道妊娠高血压综合征 (妊高征 ) 患者尿蛋白对新生儿出生体重的影响, 该研究欲探讨妊高征患者不同水平尿蛋白对新生儿出生体重的影响关系。方法: 1997年 1月 ~2004年 6月期间, 住院分娩患中、重度妊高征产妇 136例, 对新生儿出生体重与各种因素进行回归分析及t检验分析。结果: 单变量回归分析尿蛋白、孕龄分别与新生儿出生体重有高度显著性关系 (P<0. 01); 尿蛋白和孕龄一起进入多元回归分析, 校正影响因素, 尿蛋白和孕龄仍然是影响新生儿出生体重显著性因素 (P<0 .01); 与妊高征尿蛋白 ( +) 比较, 尿蛋白 无显著性影响新生儿出生体重 (P>0. 05), 尿蛋白 有显著性影响新生儿出生体重 (P<0. 01)。结论: 新生儿出生体重与妊高征患者尿蛋白丢失有关, 尿蛋白 丢失将严重影响新生儿出生体重。
