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。

Dopaminergic transmission in the hypothalamic arcuate nucleus to produce acupuncture analgesia in correlation with the pituitary gland

Acupuncture analgesia (AA) caused by low frequency stimulation of the acupuncture point (AP) was abolished by hypophysectomy and adrenalectomy. Termination of the AA producing pathway from the AP to the pituitary gland was in the medial hypothalamic arcuate nucleus (M-HARN). The origin of the descending pain inhibitory system associated with AA was in the posterior HARN (P-HARN). AA in the hypophysectomized rats, and enhanced neuronal activity in the P-HARN that were abolished during acupuncture stimulation, were both restored by intraperitoneal microinjection of 0.5 mg/kg morphine or 0.1 micrograms beta-endorphin into the P-HARN during acupuncture stimulation. Of the analgesia produced by dopamine or beta-endorphin injected into the P-HARN, that caused by beta-endorphin disappeared after denervation of the M-HARN. The P-HARN neurons that responded to acupuncture stimulation also responded to iontophoretic dopamine, but not to iontophoretic morphine nor ultramicroinjected beta-endorphin. The transmission between the M-HARN and P-HARN may be dopaminergic, and beta-endorphin might presynaptically modulate this transmission. Reduction of sodium ions may have been the reason for abolition of AA after adrenalectomy.     

我国医院医学装备的建设和管理第十二讲医学装备管理的有关事项(第五部分)

医院设备的使用管理，是指设备从到货起，经过验收入库、出库发放．财产账目、技术档案、使用率调查等一系列程序，直至设备报废为止这一全过程的管理。购置设备物质运动的全过程中．使用所占的时间最长．所以使用管理是一重要的环节。这个环节的任务，可以概括为两个方面：一是保证设备的安全，包括数量上的准确性和质量上的完好性，以便完整地保持其使用价值；二是提高设备的使用率，充分发挥设备的医疗效果，追求更多的社会效益和经济效益。医院设备的使用管理，主要包括以下内容。     

Prof. Ye Chuanhui''s Experience in Treating Nephritic Proteinuria

In the occurrence and development of glomerulonephritis, proteinuria is themain manifestation, which is easily recurrent but not easily got rid of in a short period of time. It may remain even after disappearance of the general symptoms. In some patients, there are no symptoms and signs at all in the initial stage, except proteinuria, the only distinct manifestation. Prof. Ye Chuanhui, from Chengdu University of Traditional Chinese Medicine, has accumulated rich experience for treating this disorder, which is introduced in the following.     

Treatment of ulcerative colitis by traditional Chinese medicine and dynamic study of immune functions

The effect of the traditional Chinese medicinal herbs enema and enteric-coated capsules in the treatment of ulcerative colitis (UC) were compared in 260 cases. The immune complexes and the dynamic change of autoantibodies were monitored in 28 out of the 260 cases before and after treatment. The following results were observed. (1) There was no significant difference in the total effective rate between the enema group and the oral capsule group (93.3% and 87.5% respectively), but the recovery rates of purulent hemafecia, mucusfecia and erosion accompanying colitis, etc. in the former group were higher than those in the latter (P less than 0.01). (2) The circulating immune complexes were found 43 times above the normal range in 17 cases with positive rate 60.7%, and tended to decrease as the condition became better after treatment. Antinuclear antibodies were determined by the indirect fluorescent immune method and the indirect enzyme labelling method and the positive rates were 53.6% and 64.7% respectively, both being much higher than those in the controls (P less than 0.01).

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.     

红细胞调控白细胞免疫功能新的自然实验研究体系

目的用血液免疫反应路线图实验体系评估红细胞在白细胞免疫活性中的作用。方法将0·3ml血浆加入0·2ml全血细胞悬液(全血细胞组)或0·2ml白细胞悬液(白细胞组)中,37℃温育1h,用免疫酶联法测定IL-8和IL-12水平,流式细胞仪测定白细胞膜CD4、CD8、CD35和CXCR4表达量。结果全血细胞组IL-8和IL-12水平(分别为5·96±4·26、9·84±2·23ρB·pg-1·ml-1)明显低于白细胞组(分别为15·09±9·86、13·59±3·69ρB·pg-1·ml-1,P<0·05),淋巴细胞CD4、CD35、CXCR4表达量(分别为37·79±12·00、154·66±70·00、34·40±20·45)明显高于白细胞组(分别为18·54±11·32、83·26±35·99、16·69±11·09,P<0.01),粒细胞CD35表达量(603·63±257·64)明显高于白细胞组(384·86±174·16,P<0.01)。成人全血细胞组淋巴细胞和粒细胞CD35和CXCR4表达量明显高于脐血全血细胞组(P<0·05或P<0·01)。结论红细胞是白细胞(包括T淋巴细胞、B淋巴细胞、NK细胞、树突状细胞、粒细胞等)免疫功能的调控者和指导者,脐血红细胞免疫调节功能明显下降;本研究为红细胞免疫调控活性测定提供了新的近似自然的方法。
