肝包虫囊肿的磁共振诊断

对１０例经手术证实的肝包虫囊肿（又称细粒棘球蚴病）的磁共振成像（ＭＲＩ）进行分析，认为其特征性表现为：囊壁呈光滑厚薄均一的低信号的包膜，在Ｔ２加权像上显示更加清楚；母囊内有数个大小不等的子囊，整个病灶呈多房性似玫瑰花状。本文对肝包虫囊肿与肝内其它囊性占位病变的鉴别诊断进行了探讨。     

Spontaneous subcapsular hepatic hemorrhage associated with pregnancy: Report of a case

We report herein a case of spontaneous subcapsular hepatic hemorrhage which occurred in a 33-year-old woman 1 day after she had been delivered of her second child by cesarean section following an uneventful pregnancy. She complained of right upper quadrant pain on the 1st postoperative day, and computed tomography (CT) showed subcapsular low-density masses in both liver lobes, while extravasation was demonstrated by CO₂ intraarterial digital subtraction angiography (IADSA). The hemorrhage was successfully controlled by transcatheter arterial embolization (TAE). However, on the 3rd day after TAE, an exploratory laparotomy was performed to establish an exact diagnosis to explain the persistent abdominal pain and abnormal liver function tests. Subcapsular hematomas in both lobes were confirmed and no visible laceration was present. The patient recovered gradually by spontaneous absorption of the hematomas and was discharged on the 22nd postoperative day. Spontaneous hepatic hemorrhage associated with pregnancy is a very rare complication, and establishing a correct diagnosis and initiating appropriate therapy are essential for this life-threatening disease.

原发性肝癌中医单证证型专家观点文献分析

目的整理原发性肝癌辨证分型文献中的专家观点,分析原发性肝癌各中医单证证型在专家观点中的出现状况,初步明确其主要的单证证型.方法对建国以来国内公开报道的有关原发性肝癌中医辨证分型的文献进行整理,运用χ2检验对文献中的专家观点进行统计分析.结果气滞(肝气郁结)型、血瘀型、脾气虚型、肝阴虚型、肾阴虚型、肝胆湿热型在专家观点中出现频率较高(均超过50%),它们之间没有显著性意义,但与其它出现频率较低的各单证证型相比,均有显著性差异(P<0.00091).结论原发性肝癌常见的中医单证证型依次为①气滞(肝气郁结)型;②血瘀型;③脾气虚型;④肝阴虚型;⑤肾阴虚型;⑥肝胆湿热型.     

Zinc and magnesium in liver cirrhosis

Abstract. The Authors determined zinc (Zn) and magnesium (Mg) in the plasma, urine, erythrocytes (RBCs), mono- and polymorphonuclear cells (MNCs and PMNs) of patients with overt alcoholic and nonalcoholic liver cirrhosis. In order to obtain a clearer clinical picture, biochemical and nutritional parameters (retinol, tocopherol, six different carotenoids, creatinine-height index and tricipital skinfold), as well as markers of portal hypertension (spleno-portal size and platelet count) were also evaluated.
The plasma levels of Zn and Mg were found to be reduced, as were the urine levels of Mg. Urine Zn, on the other hand, was higher than normal. Plasma Zn correlated inversely, and urine Zn directly, with the severity of the disease, rather than with alcohol consumption or treatment with diuretics. Protein metabolism impairment would appear to affect the plasma transport of Zn rather than its overall availability in the organism; the opposite was found in the case of Mg, the availability of which appeared to be reduced. Determination of the two elements in RBCs, MNCs and PMNs suggested that a true nutritional deficit cannot be demonstrated. MNCs, rather than RBCs or PMNs seem better to reflect tissue status of trace elements.     

生长激素在肝硬变门脉高压低蛋白血症手术前的应用研究

目的：研究生长激素（rhGH)对肝硬变门脉高压低蛋白血症患者手术前的治疗价值。方法：肝硬变门脉高压抑行脾切除、门奇静脉断流手术患者60例，Child分级B级，随机分为rhGH治疗组30例，对照组30例。rhGH组术前5d每天皮下注射rhGH 4IU，对照组给予安慰剂生理盐水。两组术前均行相同肠外营养支持。测定治疗前、治疗后3d、4d、5d血浆白蛋白、球蛋白、前白蛋白及空腹血糖。结果：rhGH组治疗后3d前白蛋白较治疗前及对照组明显升高（P＜0．05），治疗后4d、5d仍维持较高水平；治疗后5d白蛋白较治疗前及对照组明显升高（P＜0．05）。rhGH组患者一般情况改善，生活质量提高。对照组白蛋白、前白蛋白无明显变化。两组空腹血糖、球蛋白无明显改变。结论：rhGH联合肠外营养支持对纪正肝硬变门脉高压低蛋白血症患者术前低蛋白状态，改善生活质量有良好疗效，由于rhGH起效慢，应早期、足量、足疗程应用。     

Efficacy of preoperative portal vein embolization prior to major hepatectomy for patients with impaired liver function: A retrospective study

Hepatocellular carcinoma (HCC) is often associated with chronic liver disease, such as hepatitis or cirrhosis, and this association may limit the use of surgery as a therapy, and if surgery is pursued, may give rise to postoperative hepatic failure. We evaluated the outcome in patients with HCC given preoperative portal vein embolization (PVE) before they underwent major hepatectomy. After PVE, portal pressure increased significantly. Two weeks after PVE, both the volume of the non-embolized lobe and the 15-min indocyamine green retention rate (ICG R15) were significantly increased. The prognostic score, calculated on the basis of age, ICG R15, and the resection rate, was significantly decreased. The operative mortality rate was significantly lower in patients who underwent PVE before surgery than in patients who did not receive PVE. The cumulative survival rate of the PVE patients, even those with cirrhosis of the liver, was significantly higher. Prior PVE appears to allow more extensive major hepatectomy and to lessen the risk of this invasive surgery. However, patients in whom the portal pressure immediately after PVE was more than 30cm H₂O and/or whose prognostic score exceeded 50 points developed postoperative hepatic failure. These features should be kept in mind when it is decided whether surgery is indicated. Nevertheless, preoperative PVE appears to be a beneficial procedure for patients undergoing major hepatectomy, particularly those with chronic liver disease.     

Oxidative breakdown of octanoic acid is maintained in patients with cirrhosis despite advanced disease

As an octanoic acid 13CO2 breath test is frequently used to test gastric emptying of solid food, the purpose of the present study was to study whether oxidative breakdown of octanoic acid is affected by severe liver disease. The design of our study was twofold. First, cirrhotic patients (n = 82) of varying severity were compared with healthy controls (n = 17). Values of half-time, time point of maximal expiration and cumulative recovery of octanoic acid breath tests (OBT) were not significantly different between them. Secondly, cirrhotic patients (n = 10) were studied before placement of transjugular intrahepatic portosystemic shunt, 4-7 days later and 1-2 months later. Values of half-time, time point of maximal expiration and cumulative recovery of consecutive OBTs did not change significantly. The OBT may therefore be a suitable test in the future to detect delayed gastric emptying of solids in cirrhotic patients with reduced liver function and portal hypertension.
