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.     

Screening Mouse Genes Related to Blastocyst Implantation by Using PCR Subtraction

Objective To identify genes that may be related to embryo implantation Materials & Methods The PCR subtraction technique was applied at implantation and inter-plantation sites on day 4. 5 of pregnancy in mice. Two novel Expressed Sequence Tags (ESTs ), EST8 and EST81 were identified; their expression in tissues was analyzed by Northern blotting, and their full-length cDNAs were synthesized by PCR.Results We found that these two novel ESTs (EST8and EST81) were noticeably expressed in implantation site in the mouse on day 4. 5 of pregnancy. EST8 was expressed at high level in livers and implantation sites of the mice, while at low level in ovaries and inter-plantation sites. EST81 was predominantly expressed in implantation site and ovary, and at low level in all other tissues. Their complete cDNAs, 1 665bp and 1 264 bp respectively, were synthesized by using PCR.Conclusion The two full-length cDNAs were responsible for embryo implantation,and their functions need to be further studied.

老年及老年前期重症肌无力的手术治疗(附23例报告)

目的总结胸腺切除术治疗老年及老年前期重症肌无力的临床效果。方法对1981年～2001年在我院行胸腺切除治疗的23例老年及老年前期重症肌无力患者的手术疗效进行回顾分析。结果在所有重症肌无力患者中老年及老年前期患者所占比例小,男性为多见;全身型为主,合并胸腺瘤及危象者多;手术总有效率43.5％。结论老年及老年前期重症肌无力的手术疗效较青壮年为差,但仍是可选择的一种重要方法。     

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.
