大同市103例高龄老人营养情况及心理状况调查

本文对103名高龄老人进行营养情况调查、心理状况调查和体测量,结果表明:高龄老人体质指数大于26者很少,只要老龄人的各种营养素达到供给量标准,心理状态乐观满意,且不吸烟不酗酒者,则可长命百岁。

移植肾破裂的处理

目的　提高移植肾破裂的防治水平。方法　 6例移植肾破裂 ,手术前 2例 ,手术后 4例。 2例术前供肾破裂 ,采用切开移植肾破裂处包膜 +裂口内明胶海绵填塞 +肠线修补 +肠线编织肾袋收缩保护移植肾。 1例术后移植肾破裂早期 ,出血少 ,针对顽固性高血压采用“硝普钠”降压 ,配合常规抗排斥药物。 3例术后移植肾破裂出血量估计超过 10 0 0ml者 ,采用手术延长移植肾破裂处包膜 +裂口内明胶海绵填塞 +肠线修补 +肠线编织肾袋收缩保护移植肾。结果　 ( 1)手术前 2例手术后 4例 ,采用切开或者延长移植肾破裂处包膜 +裂口内明胶海绵填塞 +肠线修补 +肠线编织肾袋收缩保护移植肾并配合“硝普钠”降压的方法处理 ,均未再破裂出血 ,移植肾功能恢复良好。 ( 2 ) 1例术后移植肾破裂早期的患者 ,针对顽固性高血压采用“硝普钠”降压 ,配合常规抗排斥药物 ,非手术治疗成功。结论　 ( 1)采用手术切开或延长移植肾破裂处包膜 +裂口内明胶海绵填塞 +肠线修补 +肠线编织肾袋收缩保护移植肾可以有效治疗移植肾破裂。 ( 2 )移植肾破裂出血少的情况下 ,可以在密切观察下非手术治疗     

前列腺癌去雄激素治疗不良反应的预防和处理

目的观察去雄激素治疗前列腺癌的不良反应,并探讨其预防和治疗。方法回顾性分析1998年7月-2006年1月112例去雄激素治疗晚期前列腺癌的临床资料。结果112例患者中,97例完成了不良反应的调查。随访3-36月,去雄激素治疗后潮热、性功能障碍、病理性骨折发生率分别为46％、75％、4％;患者潮热、精神疲乏、四肢乏力、纳差症状明显加重(P<0．05);性功能明显减退(P<0．05)。12例潮热症状严重者使用抗抑郁药博乐欣(25mg,tid)1-2周症状减轻。7例有骨转移性疼痛或严重骨质疏松患者,应用唑来膦酸4mg静脉滴注,每45d一次,骨痛症状缓解。结论去雄激素对前列腺癌患者生活质量有一定影响。博乐欣可减轻患者潮热症状,唑来膦酸可预防和治疗去雄激素相关的骨质疏松并发症。     

Innervation of the trapezius muscle: is cervical contribution important to its function?

OBJECTIVE: To study the effect of the cervical plexus and the accessory nerve to the function of the trapezius muscle. STUDY DESIGN AND SETTING: Eighteen adult male Sprague-Dawley rats were randomly divided into three groups. The neurotomies were performed in the left sides and the right sides served as within-subject controls. In group A, the accessory nerve was transected. The C2-5 were transected in group B, and both of the accessory nerve and C2-5 were cut in group C. The electrophysiologic, myophysiologic, and histologic changes of the muscles were measured. RESULTS: There were significant differences (P < 0.05) between the three groups in the recovery rates of the transverse area of the muscles. The CMAP recorded from the experimental sides in group B were similar to the control sides. The values of the maximum tension of the tetanus contraction between the two sides showed no differences either (P > 0.05). CONCLUSION: The accessory nerve supplies the most important motor input to the trapezius. Motor innervations of the cervical plexus are not very significant.     

Loss of cables, a novel gene on chromosome 18q, in ovarian cancer.

Cables, a cyclin-dependent kinase (cdk) interacting protein, has recently been identified and mapped to human chromosome 18q11. Cables appears to be primarily involved in cell cycle regulation and cell proliferation. Overexpression of Cables in Hela and other cell lines inhibits cell proliferation and tumor formation. We hypothesize that loss of Cables expression is associated with ovarian cancer. To test our hypothesis, we examined Cables expression in the four most common subtypes of ovarian carcinomas: serous, endometrioid, mucinous, and clear cell. In addition, mucinous and serous borderline tumors were also included. Loss of Cables expression was observed at high frequency in ovarian serous (11 of 14 cases, 79%) and endometrioid (5 of 10 cases, 50%) carcinomas. In contrast, strong Cables staining was detected in all clear cell carcinomas (10 cases) and mucinous tumors (5 carcinomas and 5 borderline tumors). The majority of serous borderline tumors (11 of 14 cases, 79%) showed positive Cables staining, with the rest showing focal loss of Cables expression. Furthermore, RT-PCR revealed the lack of Cables mRNA in a human ovarian cancer xenograft. No correlation was noted between loss of Cables and histologic grade, tumor stage, and survival. In conclusion, our results indicate that loss of Cables is common in ovarian serous and endometrioid carcinomas and imply that Cables may be involved in the pathogenesis of these two types of ovarian carcinomas.
