Changes of TXA_2 and PGI_2 during Postoperative Hypertensive Crisis in Patients with Hypertensive Intracerebral Hemorrhage

In order to explore the changes and the roles of TXA2 and PGI2 during postoperative hypertensive crisis in patients with hypertensive intracerebral hemorrhage, 31 cases subject to crani-otomy were divided into three groups: group A, 9 patients with postoperative hypertensive crisis; group B, 13 patients without postoperative hypertensive crisis; and group C, 9 patients without his-tory of hypertension and hypertensive intracerebral hemorrhage. TXA2, TXB2, 6-keto-PGF1α and PGI2 were measured after operation in the three groups respectively. The postoperative blood pres-sure in group A, including SBP and DBP, was elevated more obviously than that in the other two groups. TXA2 and PGI2 in group A were significantly higher than those in other two groups (P<0.01). Moreover, the ratio of TXB2 to 6-keto-PGF1α in group A was significantly higher than that in other two groups (P<0.05). The increase of TXA2 and the relative inadequacy of prostacyclin, especially 6-keto-PGF1α, may play roles in the postoperative hypertensive crisis. And the increased value of TXB2 to 6-keto-PGF1α could provide the basis for diagnosis of postoperative hypertensive crisis.

Risk Factors for Fatal Recurrence of Liver Transplant Recipients with Hepatocellular Carcinoma in the First Year

Objective： To investigate the clinicopathological risk factors for fatal recurrence of hepatocellular carcinoma （HCC） in orthotopic liver transplant recipients in the first year. Methods： From April 2002 to October 2005, 303 recipients who received orthotopic liver transplantation for HCC were reviewed. Of These patients, those who demonstrated diffuse intra-hepatic or multiple systemic recurrent lesions and died within 1 y after surgery were investigated （fatal recurrence group, 48 cases）. The remaining patients were designated as the control group, and the two groups were compared for clinicopathologic risk factors by logistic regression analysis. Results： Among the 303 patients reviewed, 48 patients were enrolled in the fatal recurrence group （15.84%）. Multivariate analysis between the fatal recurrence group and control group showed that the presence of vascular invasion, tumor size greater than 6.5 cm, and pre-operative serum alpha-fetoprotein （AFP） level greater than 1000 ptg/L were the risk factors in the fatal recurrence group. 85.71% of the patients who had all the three risk factors, 37.84% of those who had two risk factors, 13.64% of those who had one risk factors, and 6.71% of those who had none risk factors died because of recurrence within 1 y after transplantation. Conclusion： Three distinct risk factors attributed to fatal recurrence of liver transplant recipients for HCC are vascular invasion, tumor size ≥6.5 cm, and pre-operative serum AFP level ≥1000 μg/L. The high risk HCC patients with two or more risk factors should not to be the candidates for liver transplantation.     

高原地区不典型肺结核的X线征象分析

目的分析高原地区不典型肺结核的X线表现。方法不典型肺结核组184例。肺炎组200例,均摄常规X线胸部平片。分析各自的影像学表现,并进行统计学分析。结果不典型肺结核组184例经短期内抗炎治疗无好转或病灶有进展,转为抗结核治疗后病灶已完全愈合。结论高原地区不典型肺结核X线表现有其分布特点,影像学表现多种多样,传统X线片仍不失为首选的检查方法。

药物所致阴茎持续勃起的诊断及治疗

1977年有人在行阴茎血管手术时偶然发现在阴茎海绵体内注入罂粟碱,阴茎勃起可持续2小时之久。1983年Brindly报告,海绵体内注入酚苄明勃起可达30小时。其后Virag及Zorgnitti几乎同时单用罂粟碱或合用酚妥拉明于阴茎根部注射治疗阳萎。近几年来,阳萎治疗的重要进展就是血管活性药物罂粟碱及α-肾上腺素能阻滞剂的使用。目前国内也有人用以上两种药物治疗阳萎。这样就增加了药物所致阴茎持续勃起(pharmacologically induced prolonged erection,PIPE)的发生机会。一、血管活性药物的作用机理阴茎勃起是由神经冲动引起的,神经冲动是由盆神经(含副交感神经纤维)及腰交感     

鼻咽癌、喉癌及恶性淋巴瘤患者血清铁蛋白水平的分析

本文测定头颈部恶性肿瘤患者共91例,包括鼻咽癌4例,喉癌28例,恶性淋巴瘤23例和148例健康人(作为正常对照),其血清铁蛋白水平均为年老者高于年青者,男性高于女性。不论按年龄还是按性别分组比较,肿瘤组的血清铁蛋白水平均明显高于同年龄,同性别正常对照组,且年青患者较年老患者增高明显,女性患者较男性患者增高明显,而以青年女性患者增高最为显著。各肿瘤组间比较无显著差异。血清铁蛋白放免测定可以作为鼻咽癌、喉癌和恶性淋巴瘤的辅助诊断方法。
