选择性肾动脉栓塞治疗肾剌伤的临床应用

目的:探讨选择性肾动脉栓塞治疗肾损伤的优越性及其临床应用。材料与方法:同时使用两种栓塞材料——可吸收的明胶海棉条和美国COOK公司产38-3-5弹簧栓子,治疗了两例肾剌伤患者,两例均为男性,年龄分别为20和35岁。结果:两例患者肾刺伤后均经受过保守治疗,治疗时间分别为14和22天,但未奏效。经超选择性肾内动脉分支栓塞、取得了十分满意的止血效果,后随访3～4年,患者一切感觉正常。结论:选择性肾动脉栓塞治疗肾刀刺伤后肾出血是一种安全、可靠、有效的方法。     

Late Effects of Childhood Acute Leukemia and Its Treatment

Late effects of childhood acute leukemia and its treatment were studied in 766 patients (684 ALL, 73 ANLL, and 9 others) in Japan who had remained in remission for more than 1 year after their first complete remission. Delayed adverse sequelae involve a wide variety of organs and their functions. Short stature was present in 2.61%, obesity in 3.79%, abnormalities of growth hormone secretion in 1.5%, delayed secondary sex characteristics in 1.5% of males and 0.6% of females, motor disturbances in 1.17%, sensory disturbances in 0.91%, intellectual and learning disabilities in 2.48%, abnormal findings in routine neurologic examinations in 1.31%, EEG abnormalities in 4.30%, brain CT abnormalities in 5.09% and cardiac dysfunction in 1.07%. Various other disorders were seen in 20 patients. Many of these delayed adverse sequelae are caused by or related to central nervous system prophylaxis and systemic combination chemotherapy. The results suggest that it is needed to improve therapeutic methods through the stratification of patients by risk factors and detailed analysis of prognostic factors. Moreover it is important to render medical and psychosocial support to long-term survivors of childhood leukemia through interactions between the patient, parents and medical staff.     

慢性前列腺炎IL—8和NO水平测定初探

对６２例前列腺液标本进行白细胞介素８（ＩＬ－８）和一氧化氮（ＮＯ）含量的测定。结果示，对照组全部阴性；慢性前列腺炎组和非前列腺炎组细菌，支原体和衣的体培养及ＮＯ检测结果差异均无显著怀；慢性前列腺炎组ＩＬ－８阳性检出率明显高于非前列腺炎组，差异非常显著。提示检出ＩＬ－８可作为前列腺感染的诊断指标。     

甲状腺病变患者血清Leptin的浓度变化

目的探讨甲状腺病变患者血清瘦素(leptin)浓度的变化及意义.方法本文用放射免疫分析(RIA)方法测定了114例甲状腺病变患者血清Leptin和总睾酮(TT)的浓度.结果统计学处理结果显示各病变组男性与正常对照组男性间,Leptin和TT的浓度差异均有显著性意义.结论血清Leptin的浓度变化可作为了解甲状腺病变患者营养状况的辅助指标.     

Fusiform posterior cerebral artery aneurysm treated with excision and end-to-end anastomosis. Case report

A case of a ruptured fusiform aneurysm of the posterior cerebral artery is reported. The aneurysm was excised and end-to-end anastomosis was carried out between the two ends of the posterior cerebral artery. There is no previous report of a posterior cerebral artery aneurysm treated with this technique. The pertinent literature is reviewed and the significance of this technique in the treatment of unclippable cerebral aneurysms is discussed.     

CLINICAL ANALYSIS OF FOUR CHINESE HEMOPHILIACS WITH HUMAN IMMUNODEFICIENCY VIRUS INFECTION

Human immunodeficiency virus (HIV) is now considered as the causative agent of acquired immunodeficiency syndrome (AIDS). A high risk of AIDS has been reported among patients with hemophilia who received lyophilized commercial factor VIII and IX concentrates of American origin. At a prevalent survey from September to December 1985, HIV antibodies were found in all four patients with hemophilia treated with the batch number W87307, 955 I.U. of American commercial factor VIII concentrate supplied by Armour Pharmaceutical Company, USA. One of the sero-positive patients developed AIDS-related complex (ARC) and died of cerebral hemorrhage. The other three sero-positive patients had abnormalities in cell-mediated immunity. Of them two developed left lumbosacral radiculopathy and hemorrhagic herpes zoster and one remained well so far.     

Presence of ghost cells and the Wnt signaling pathway in odontomas

BACKGROUND: Although it has been reported that ghost cells are present in odontomas, the generation mechanism of these cells is unclear. To evaluate the presence of ghost cells and involvement of the Wnt signaling pathway, we examined the expression of hard keratins, beta-catenin and Lef-1 in odontomas. METHODS: Sixty-nine cases of odontoma were examined immunohistochemically with the use of antibodies against human hair proteins, beta-catenin and Lef-1. RESULTS: Expression of hard keratins was found only in the cytoplasm of ghost cells in 46 (66.7%) of the 69 odontomas. Compound odontomas (78.8%) showed a higher incidence of ghost cells than complex odontomas (29.4%). Histopathologically, ghost cells were found within odontogenic epithelium adjacent to immature enamel and in the centre of Liesegang-ring-like calcified materials. Expression of beta-catenin and Lef-1 was observed in the cytoplasm and nucleus of odontogenic epithelial cells adjacent to the ghost cells in immature odontomas. CONCLUSION: These findings suggest that odontoma is a hard keratin-expressing tumor-like lesion, and that the Wnt signaling pathway may be involved in the formation of ghost cells in odontomas.
