创伤后肝细胞凋亡与坏死的检测及其意义

目的 探讨严重创伤后肝细胞凋亡及坏死在急性肝功能障碍发病机制中的作用。方法复制多发性骨折合并休克的大鼠创伤模型,采用 Annexin－V－Flous、碘化丙锭(propidium iodid,PI)双标法经流式细胞仪检测创伤后各时间点肝细胞凋亡与坏死的数量变化,结合光镜、电镜和电泳观察细胞凋亡与坏死,并与肝功能变化相比较。结果创伤后早期肝细胞即发生凋亡和坏死,坏死肝细胞的数量进行性升高,与肝功能变化显著呈正相关;凋亡肝细胞在创伤后3h达高峰,部分凋亡肝细胞发生继发性坏死,其数量与肝功能变化显著正相关。结论肝细胞坏死与凋亡是严重创伤后肝功能损害的重要原因,坏死肝细胞是肝功能损害的直接因素,凋亡肝细胞通过发生继发性坏死加重肝功能损害。

多节段髓内星形细胞瘤的临床研究

目的 探讨不同年龄段、恶性程度不同的多节段髓内星形细胞瘤患者的诊治特点.方法 21例多节段(3个椎体节段以上)髓内星形细胞瘤患者均行后正中入路显微镜下肿瘤切除术,以UOA分值差(术后UOA和术前UOA差值)评估手术效果.以Logistic回归和多元线性同归分析统计学数据.结果 肿瘤性质直接影响肿瘤的切除程度(X2=10.41,P=0.03),高度恶性肿瘤只能大部切除或减压.年龄(X2=12.53,P=0.01)、肿瘤性质(X2=16.44,P=0.002)和部位(X2=27.12,P=0.04)影响近期手术效果(UOA分值差);青少年患者、低度恶性肿瘤手术效果较好,单纯累及胸段的患者手术效果差.结论 低度恶性或青少年多节段髓内星形细胞瘤患者应尽早手术,术后疗效满意.     

"Three-Grade Criteria" of Radical Resection for Primary Liver Cancer

OBJECTIVE The present study was designed to develop the "ThreeGrade Criteria" for radical resection of primary liver cancer (PLC) and to evaluate its clinical significance.METHODS Criteria for radical resection of PLC were summed up to 3 grades based on criterion development. Grade I: complete removal of all gross tumors with no residual tumor at the excision margin. Grade Ⅱ: on or the primary branches of the portal vein, the common hepatic duct or its dition to the above criteria, negative postoperative follow-up result including AFP dropping to a normal level (with positive AFP before surgery)within 2 months after operation, and no residual tumor upon diagnostic imaging.The clinical data from 354 patients with PLC who underwent hepatectomy were reviewed retrospectively. Based on the "Three-Grade Criteria" these patients were divided into 6 groups: Grade Ⅰ radical group,Grade Ⅰ palliative group, Grade Ⅱ radical group, Grade Ⅱ palliative group,Grade Ⅲ radical group, Grade Ⅲ palliative group. The survival rate of each group was calculated by the life-table method and the rates compared among the groups.RESULTS The survival rate of patients receiving radical treatment was better than those receiving palliative treatment (P＜0.01). Survival improved as more criteria were applied. The 5-year survival rate of the patients in Grade Ⅰ, Ⅱ and Ⅲ who underwent radical resection was 43.2%,51.2% and 64.4%, respectively (P＜0.01).CONCLUSION The "Three-Grade Criteria" may be applied for judging the curability of resection therapy for PLC. The stricter the criterion used,the better the survival would be. Adopting high-grade criteria to select cases and guide operations and strengthening postoperative follow-up would improve the results of hepatectomy for PLC.     

Primary aspergillosis of the sphenoid sinus with pituitary invasion – a rare differential diagnosis of sellar lesions

Summary Aspergillosis belongs to the group of mycotic diseases of paranasal sinuses. The invasive forms, and particularly the fulminant forms, are potentially fatal. Isolated aspergillosis of the sphenoid sinus or the clivus is a difficult diagnosis, since the often misleading clinical manifestations of this rare disease develop late. These patients become apparent by neurological signs such as cavernous sinus syndrome, pseudotumor of the pituitary or the orbit. Diagnosis is often made intra-operatively or on histological examination. We report a case of invasive aspergillosis uniquely involving the sellar area revealed by clinical features suggesting a pseudotumor of the pituitary. Although such lesions are almost always seen in immune suppressed subjects, in our case, the patient was immune competent and had no past history of sinusitis. The question of whether, and when to perform limited or extensive surgery remains an issue for discussion, owing to the rarity of this disease honed by lack of experience. It depends on several factors: the kind of disease, the immunity, the subtype of invasive fungal sinusitis and the degree of tissue invasion.     

螺旋CT三期扫描对肝纤维化诊断价值研究

目的探讨螺旋CT三期扫描对肝纤维化的诊断价值。方法对66例经肝穿刺活检病理证实的慢性乙型肝炎肝纤维化患者组和42例正常对照组进行螺旋CT三期增强扫描。根据纤维化程度分期进行影像资料和相关指标的统计分析。结果肝左叶增大,肝表面形态及肝实质密度的改变,脾脏增大,门静脉增宽和侧枝循环的建立等影像学改变,随着肝纤维化严重程度的加重而有统计学差异。本研究显示57例肝纤维化患者螺旋CT三期扫描诊断肝纤维化52例,敏感性91.2%,特异性77.8%。各期肝纤维化分期准确28例,准确率49.1%;准确判断轻度纤维化(S1、S2)或重度纤维化(S3、S4)44例,准确率77.2%,诊断早期肝硬化16例,准确率84.2%。结论螺旋CT三期扫描能判断肝纤维化的程度,而且是动态观察肝纤维化的病程演进和临床随访的有效手段。     

Lower limb blocks for children

Femoral and lateral cutaneous nerve of the thigh blocks have been performed in a group of 50 children; the method has not previously been described in paediatric practice. The technique was judged to have been successful in 48 (96%) of the children. There were no early or late complications. It is concluded that these blocks are easy to perform, even in small children and infants, and that they can produce reliable postoperative analgesia for a variety of orthopaedic and plastic procedures.     

Increased plasma cathepsin D concentration in hepatic carcinoma and cirrhosis but not in breast cancer

Using a sandwich enzyme-linked immunoassay, plasma total cathepsin D concentration was assayed in 40 breast cancer patients and 84 patients with various liver diseases and compared to that of 52 normal subjects. There were no significant variations found in breast cancer patients related to tumor size, node invasiveness or metastases. In normal women, cathepsin D levels were slightly but not significantly increased in the luteal phase and in pregnancy. By contrast, plasma cathepsin D concentration was significantly increased in 70-75% of patients with liver disease (cirrhosis, hepatocarcinoma, hepatitis), but not in those with liver steatosis. Cathepsin D was independent of most of the plasma hepatic function tests and was correlated with alpha-fetoprotein in cirrhosis and with alpha-fucosidase in primary hepatocellular carcinoma. We conclude that plasma cathepsin D is not a useful marker in breast cancer. However, since the cellular level of this protease is associated with risk of metastasis in breast cancer, clinical follow-up will be required to test whether high cathepsin D plasma concentration has any prognostic value in liver cirrhosis and primary hepatocarcinoma.
