Management of hepatocellular carcinoma presenting as obstructive jaundice

Eleven (3%) of 340 patients with hepatocellular carcinoma (HCC) presented with obstructive jaundice. The tumor extensively infiltrated the major bile ducts in eight patients. Jaundice was relieved by endoscopic endoprosthesis in four patients, nasobiliary drainage in two patients, percutaneous transhepatic stenting in one patient, and surgical intubation in one patient. The survival interval of these eight patients (mean +/- SD) was 35 +/- 20 days. Three patients had tumor fragments in the common bile ducts. In two patients, major hepatic resection was done after initial tube decomposition of the biliary system. One patient remained tumor-free on follow-up at 24 months, and the other patient had recurrent tumor detected on follow-up at 17 months after surgery. The tumor was irresectable in the third patient. Multiple surgical and endoscopic procedures kept the bile duct patent for 17 months before the patient died of the disease. Not all patients who present with obstructive jaundice due to HCC are terminally ill. With proper management, good palliation and occasional cure are possible.     

角膜损伤后神经再生的实验研究

应用神经组织化学技术观察了兔角膜NA能神经及AchE阳性神经在角膜损伤后的再生,证实术后1月,两种神经均有再生轴突进入植片;术后3月可见交界区和植床内神经密度明显增加;同时,对术后两种神经再生的功能意义进行了讨论。     

血管内氧合器的研制

为了探索呼吸辅助的新方法，我们采用国产聚丙烯中空纤维，自行设计、制造模具，研制出一种血管内氧合器。该氧合器是一个小的、细长的可经单侧股静脉或颈静脉切开，置入腔静脉内的装置。氧合器有效长度４０ｃｍ，膜交换面积０．０９ｍ＾２。经负压调节通过血管内氧合器的氧流量，以防止纤维破裂造成的血管内气栓的危险。一根双腔导气管使气体经同一静脉切开部位循环，气体经内芯管流经血管内氧合器尖端，然后经中空纤维束流出。目前     

急性肾功能衰竭的治疗进展

目的：探讨急性肾功能衰竭的治疗。方法：复习有关急性肾功能衰竭的治疗文献，作一总结。结果：使用人工合成三肽序列（RGD）的多肽、生长因子、心房利钠因子和人工肾小管治疗急性肾功能衰竭都取得了较好的疗效。结论：这些新的治疗可望改善急性肾衰的预后和降低死亡率。     

肠溶阿斯匹林剂量和血阿斯匹林及水杨酸盐浓度与药效关系探讨

本文探讨了ＡＳＡ剂量与药效的关系及血ＡＳＡ、ＳＡ药物浓度监测的临床意义，结果表明：（１）ＡＳＡ剂量与６－ｋｅｔｏ－ＰＧＦ_（１α）抑制率呈正相关（Ｐ＜０．０１），而与ＴＸＢ_２及ＰＡｇＲ抑制率无相关性（Ｐ＞０．１）；（２）本文采用ＨＰＬＣ内标法同时测定血ＡＳＡ和ＳＡ浓度，结果准确，方法简便；（３）当口服小剂量ＡＳＡ防治ＣＩ时，监测血ＡＳＡ和ＳＡ以调整ＡＳＡ用药剂量的临床价值并非十分重要。     

Clinical analysis of congenital bile duct dilatation: Experience with 160 patients over a 7-year period

From July 1989, to June 1996, 160 patients with congenital bile duct dilatation (CBD) were treated at our institution. The incidence of CBD at our institution has increased annually. In approximately 90% of patients with CBD there was associated anomalous arrangement of the pancreaticobiliary ductal system, and we concluded that this was one of the main causes of CBD. Pediatric endoscopic retrograde cholangiopancreatography was first introduced to China in 1989, and has been successfully performed in 90.2% of 92 patients at our institution. We found that age at diagnosis was closely related to the subtype, complications, and mortality of CBD. The subtype also correlated with the presenting symptoms. One hundred and forty-seven of the 160 patients underwent surgery. Of these 147 patients, 136 (92.5%) were cured with normal liver function and 9 (6.1%) improved with liver impairment. Two patients died, one of postoperative pneumonia and one of liver failure. We conclude that early radical surgery and careful postoperative follow-up are essential in the prevention of CBD complications such as cholangitis, pancreatitis, biliary stones, and development of carcinoma. This article is based on a special lecture delivered before the 19th meeting of the Japanese Society of Pancreatico-biliary Maljunction, on September 14, 1996, in Tokyo     

益气平喘丸的药理研究
