原发性肝癌HBV感染模式与AFP水平相关性研究

目的:探讨原发性肝癌(PHC)患者乙肝病毒(HBV)感染模式与血清甲胎蛋白(AFP)水平的关系。方法:应用酶免疫检测法(ELISA)、聚合酶链反应(PCR)及放射免疫技术分别测定100例原发性肝癌患者血清乙型肝炎病毒指标(HBV-M)及AFP。结果:100例PHC患者中,HBV-M阳性88例(88％),阴性12例(12％),HBV-M阳性者AFP水平高于阴性者147 ng/mL,二者有非常显著性意义(P<0.01),且HBV-M阳性者AFP升高(68.4％)的比例明显高于HBV-DNA阴性者(31.6％)(P<0.01)。PHC患者HBV感染模式分析中,HBsAg、HBeAb、HBcAb阳性和HBV-DNA阳性最多,为56例(63.6％),其次为HBsAg、HBeAg、HBcAb和HBV-DNA阳性,为9例(10.2％)。结论:HBV是原发性肝癌发生的重要原因,在PHC患者中,AFP升高与HBV感染、复制相关。     

Double-bundle technique: Endoscopic posterior cruciate ligament reconstruction using tibialis posterior allograft

Recently, attention has been given to the double-bundle technique for treating the posterior cruciate ligament (PCL)-deficient knee. We present an arthroscopic PCL reconstruction using a double-bundle technique with 3-stranded tibialis posterior (TP) allograft that has not been described before. The anterolateral bundle of the PCL is reconstructed using 2-stranded TP allograft and the posteromedial bundle using 1-stranded TP allograft. Three-stranded TP allograft will be an alternative graft choice for PCL reconstruction.

湿性皮肤再生技术在皮肤擦伤的应用

目的:探导湿性皮肤再生技术治疗皮肤擦伤的疗效。方法:自2000年1月-2005年10月,治疗头面部、躯干和四肢急性皮肤擦伤共353例,其中采用湿润烧伤膏和暴露疗法治疗(新法组)185例,按传统疗法清创治疗(传统组)168例。结果:新法组7天内痊愈116例,占62．7％;14天内痊愈59例,占3713％;总有效率100％。传统组7天内痊愈82例,占48．8％;14天内痊愈58例,占34．5％;另外28例,占16．7％,发生不同程度的创面感染,痂下积脓,需作再次清创,碘伏湿敷或改用MEBO治疗,创面延期愈合,愈后瘢痕增生明显。结论:湿润烧伤膏和暴露疗法治疗皮肤擦伤与传统疗法比较,具有缩短创面愈合时间,愈后不留瘢痕等优点。

羊踯躅根治疗慢性肾小球肾炎的实验及临床研究

本文用反复静脉注射小剂量牛血清白蛋白复制家兔慢性肾炎,用羊踯躅根治疗。同时,用该药对慢性肾炎病人进行疗效观察。阳性组兔肾小球呈现中至重度颗粒形免疫荧光,肾组织呈明显慢性硬化性肾小球肾炎改变。尿蛋白±～++。治疗组兔及病人治疗后病变及症状均明显减轻或消失。结果提示循环免疫复合物反复沉着可引起兔类似人类的慢性硬化性肾小球肾炎,羊踯躅根对病变有一定的控制和治疗作用,这可能与其抑制免疫发病机制有关。     

Ion conductances of isolated cortical collecting duct cells

The study of ion conductances in the intact cortical collecting duct (CCD) with the patch-clamp method is rather difficult. An optimized method to isolate CCD cells from rat kidneys using an in vivo followed by an in vitro enzyme digestion is described. Individual CCD segments were collected after this digestion and incubated in EGTA-buffered medium. This procedure resulted in single cells or cell clusters. These freshly isolated CCD cells were studied with different modifications of the patch-clamp method. Membrane voltages measured in the cell-attached-nystatin configuration were –74 ±1mV (n=13) and –68±3 mV (n=22) in cells isolated from normal and mineralocorticoid-treated rats respectively. These values and those measured with the nystatin-perforated slow-whole-cell configuration (–79 ±1mV, n=23) are comparable to those measured in principal cells of isolated CCD segments. The cells hyperpolarized after the addition of amiloride and depolarized with the addition of adiuretin to the bath. The amiloride effect was enhanced when cells were isolated from deoxycorticosterone-acetate-treated rats. The cells were strongly depolarized upon elevation of the extracellular K⁺-concentration and did not demonstrate a measurable Cl^– conductance. A large-conductance K⁺ channel (174 pS, n=5, cell-attached, 145 mmol/l K⁺ in the pipette; 140 pS, n=12, cell-free, 3.6 mmol/l K⁺ in the bath) was seen. It had a very low activity on the cell, but a high open probability when excised into a solution with 1 mmol/l Ca²⁺ on the cytosolic side. More often a small-conductance K⁺ channel (36–52 pS, n=19, cell-attached; 30 pS, n=5, cell-free) with a high open probability was found on the cell. These freshly isolated cells seem to be a powerful preparation to study the properties and regulation of ion conductances of rat CCD with several electrophysiological methods. These freshly isolated CCD cells maintain the conductance properties known from principal cells of the intact CCD.     

New regimen for interpleural block in children

A new regimen for postoperative analgesia after thoracic surgery is proposed. Eight children received an interpleural infusion using bupivacaine 0.1% in a regimen from 0.5 ml·kg^?1·h^?1 up to 1 ml·kg^?1·h^?1, for 48 h according to the pain scores. The plasma levels after 24 h and 48 h were measured as well as the pleural level and in two patients the free fraction of plasma bupivacaine and the plasma PPX (a metabolite of bupivacaine) and one patient the orosomucoid (main plasma protein involved in bupivacaine protein binding) were also measured pre and postoperatively. The results shows the safety of such a regimen, for two days of postoperative analgesia.     

Kathon® CG reactivity in 1396 consecutively patch tested patients in the Copenhagen area

In 1396 consecutively patch tested patients 18 (1.3%) reacted to Kathon CG. Relevance was established in 4 of the 18 patients. The frequency of positive reactions to Kathon CG in eczema patients seems to have been stable in Denmark during the period 1983 to 1988.
