中国女性的生殖健康权力

<正> 中国的计划生育工作和人口控制的进程取得了举世瞩目的成就,中国妇女在这方面做出了巨大的贡献。在目前的生育调节工作中,妇女承担了几乎全部的生育调节和养育子女的责任及义务。社会、家庭甚至妇女本身都默认和接受了这种程式化的规范。

善存片联合健脾理气中药预防肿瘤患者化疗所致口腔溃疡的临床观察

目的观察在全身化疗前应用善存片联合健脾理气中药对肿瘤患者口腔溃疡的预防作用。方法将66例肿瘤患者随机分配为治疗组和对照组，每组33例。在全身静脉化疗前3天开始，治疗组每天口服善存片1片及健脾理气中药1剂，对照组服用维生素B：治疗，两组服药化疗后10天为1个疗程。每周期化疗结束后统计口腔溃疡的发生率，共4周期。结果治疗组口腔溃疡的发生率显著降低（P〈0．01）。结论善存片联合健脾理气中药可有效预防及治疗肿瘤患者化疗所致的口腔溃疡。     

跨步或不跨步下的前弓步和侧弓步动作中的髌股关节压力与应力(二)

结果 髌股关节的压力与应力随膝关节屈曲角度的增加而升高,随膝关节屈曲角度的减小而降低(图3～8).不同膝关节屈曲角度下弓步变化和跨步变化的髌股关节压力见表1.     

保留肾单位手术治疗早期小肾癌21例临床分析

OBJECTIVE: To evaluate the clinical effects of nephron-sparing surgery in patients with early-stage small renal cell carcinoma. METHODS: Nephron-sparing surgery was performed in 21 patients with renal cell carcinoma including 1 with solitary kidney, 3 with unilateral tumor and contralateral renal compromise, and 17 with unilateral tumor and normal contralateral kidney. The diameter of the tumors ranged from 1.5 to 6.0 cm, with a mean of 2.8 cm. The tumor diameter in 17 patients with normal contralateral kidney was less than 4 cm (mean 2.5 cm) and the average diameter in 4 patients with contralateral renal compromise was 4.2 cm. Sixteen cases were in stage T(1), 4 in stage T(2), and 1 in stage T(3). Of the 21 patients, 4 underwent tumor enucleation, 10 polar nephrectomy and 7 wedge resection. RESULTS: All patients were followed up for an average of 40.8 months (7 to 66 months). One patient suffered a right lung and mediastinum metastasis 3 years after the surgery later and 1 with chronic glomerulonephritis required dialysis 27 months after the operation. No surgical complication or local recurrence were found in other patients. CONCLUSION: As a safe and effective therapy for early-stage small renal cell carcinoma, nephron-sparing surgery can be considered as the gold-standard therapy for patients with lesions less than 4 cm in T(1) and T(2) stages of localized unilateral tumor with normal contralateral kidney.     

Lipid extract from completely sporoderm‐broken germinating Ganoderma sinensis spores elicits potent antitumor immune responses in human macrophages

Ganoderma sinensis has been used widely in Oriental countries for the prevention and treatment of various diseases including cancer. Previous studies have shown that the lipid extract from Ganoderma exhibits direct cytotoxicity against tumor cells. Here, it is reported that the lipid extract from germinating G. sinensis spores, at lower concentrations that have no direct tumoricidal activity, induce potent antitumor immune responses in human monocytes/macrophages. Upon stimulation with the lipid extract, monocytes/macrophages exhibited markedly increased production of proinflammatory cytokines and surface expression of costimulatory molecules. Conditioned medium from stimulated cells effectively suppressed the growth of tumor cells. Apparently, the lipid extract triggered macrophage activation via a mechanism different from that associated with LPS. Moreover, it was observed that the lipid extract could partially re‐establish the antitumor activity of the immunosuppressive tumor‐associated macrophages. These results indicated that in addition to its direct tumoricidal activity, the lipid extract from G. sinensis spores could exert antitumor activity by stimulating the activation of human monocytes/macrophages.

非依赖型糖尿病全血低切变率粘度值的临床意义

目的:为了探讨非依赖型糖尿病全血低切变率粘度值测定的临床意义。方法:对91例非依赖型糖尿病血液流变学低切率粘度值进行了检测,并对其结果及形成机制进行了分析讨论。结果:91例非依赖型糖尿病低切变率粘度值和对照组相比有显著性差异,p<0．01。结论:非依赖型糖尿病全血低切变率粘度增高,可造成微血管循环障碍,是非依赖型糖尿病易形成心梗、脑梗及其他微血管病的一种重要因素。
