A brief history of studies on anti-tumor remedies in China

This paper gives a general introduction to the studies on the formulation and invention of anti-tumor remedies from 1950s-1980s. Beginning from 50s, antitumor antibiotics were investigated. New alkylicompoun and antibiotics were found in the 60s, while more new natural compounds were found in the 70s. Researches were proceeded in the 80s based on the former achievements. Through the process of about 30 years, nearly 80 new species were produced, many anti-tumor pharmaceutical corporations established, and a contigent of high level research workers was formed. However, there still exist a rather large gap between the urgent clinical needs for clinical chemotherapeutics and the actual status. Based on some 30 years of experience in China, the following points were summarized, i.e., shifting from merely imitation to invention, developing the spirit of massive cooperation, investigating the thesaurus of TCM, developing China's plant resources, and traditional Chinese preventive idea, so that the stress point for research be laid on the invention of preventive anti-tumor remedies.

Microcirculation in unphysiological flaps at early stage after operation: an experimental study]

Microcirculation and blood perfusion in unphysiological flaps were observed with rabbit ear microcirculation chamber. The microcirculation of the venous flap in two days after operation was reestablished mainly by diversion of blood flow through the "to and fro" movement of venous blood. Arteriovenous anastomoses were gradually opened, resulting in the microcirculation to restore normal perfusion, venous blood through the anastomoses into arteriole then to capillaries. The microcirculation of arterialized venous flaps was almost the same as that of the venous flaps. In two days after operation, the diversion of blood flow perfused the capillaries under high pressure, so that the flow velocity and rate were much faster and larger than those of the venous flaps. The microcirculation of venouslized arterial flap, nourished by venous blood through the arterial system, was the same as that of the physiological flap. But the capillaries were perfused venous blood flow, and the blood flow velocity and rate were much slower and smaller than those of the physiological flap.     

生长期儿童股骨干骨折髓内针内固定的远期观察

作者从1970～1985年收治生长期儿童股骨干骨折305例,其中切开复位髓内针内固定34例(38处股骨骨折),并进行了5～17年的长期随访观察,发现无1例出现术后早期并发症,12例(占33.3％)出现大粗隆发育受阻的晚期并发症。18例(22处股骨骨折)双下肢等长,13例患肢较健侧长0.8～1.4cm平均1.03cm,1例合并有下肢动脉损伤者出现下肢短缩。作者认为无论采用梅花型髓内针内固定,还是三棱型髓内针内固定都是可行的,但梅花型髓内针内固定有出现大粗隆发育受阻的危险。     

Effect of melatonin on the regulation of proenkephalin and prodynorphin mRNA levels induced by kainic acid in the rat hippocampus

The in vivo short-term effect of melatonin on kainic acid (KA)-induced proenkephalin (proENK) or prodynorphin (proDYN) mRNA, and on AP-1 protein levels in the rat hippocampus, were studied. Melatonin (5 mg/kg) or saline was administered intraperitoneally (i.p.) to rats 30 min prior to and immediately after i.p. injection of KA (10 mg/kg). Rats were sacrificed 1 and 3 h after KA injection. The proENK and proDYN mRNA levels were significantly increased 3 h after KA administration. The elevations of both proENK and proDYN mRNA levels induced by KA were significantly inhibited by the preadministration with melatonin. The increases of proENK and proDYN mRNA levels induced by KA were well-correlated with the increases of c-Fos, Fra-2, FosB, c-Jun, and JunB protein levels, which were significantly increased 3 h after KA administration and effectively inhibited by administration with melatonin. In an electrophoretic mobility shift assay, both AP-1 and ENKCRE-2 DNA binding activities were increased by KA, which were also attenuated by the administration of melatonin. In addition, cross-competition studies revealed that AP-1 or ENKCRE-2 DNA binding activity was effectively reduced by the 50x unlabeled cross-competitor. Therefore, these data suggest that melatonin has an inhibitory role in KA-induced gene expression, such as proENK and proDYN mRNA expression, and this may be due to a reduction of KA-induced AP-1 or ENKCRE-2 DNA binding activity.     

超声观察肝癌多次肝动脉栓塞术治疗前后肝脏声像图的变化及其预后的评估

目的探讨超声在评估肝癌肝动脉栓塞术后肝硬变受损程度方面的价值.方法对43例原发性肝癌患者进行了肝动脉栓塞术前与术后临床肝功能检查及超声分析.结果多次肝动脉栓塞术后肝硬变程度加重,根据Child‘s分级肝功能下降率达67.4%,超声检查肝硬变加重率达70%.两者检查结果相一致.结论超声观察肝内回声的变化对评估多次肝癌肝动脉栓塞术后肝功能损害程度有重要作用.

促性腺激素释放激素激动剂及联合激素反加疗法治疗子宫内膜异位症对骨密度1年的影响

目的：比较促性腺激素释放激素激动剂（GnRH-a)联合与不联合激素反加疗法治疗子宫内膜异位症随访1年对骨密度的影响。方法：对34例确诊为子宫内膜异位症及子宫肌腺症患者随机分成两组：A组17例，Goserelin3.6mg,皮下注射，4周1次；B组17例，Goserlin同A组＋倍美力0．3mg(每日口服1次）＋安宫黄体酮5mg（每日口服1次），疗程12－24周，比较两组治疗后血激素水平及治疗后24周，停药后6个月，12个月骨密度变化。结果：两组血雌二醇均降至绝经期水平，A组比B组下降更明显（P＜0．05），A组于治疗24周、停药后6、12个月腰椎骨丢失率分别为4．15％，3．02％和1．45％，股骨颈骨丢失率分别为2．93％，2．13％和0．87％；B组分别为2．39％，1．75％，0．44％和17．5％，1．12％，0．28％，结论：GnRH-a联合激素反加疗法与GnRH-a一样在治疗期间保持低雌激素状态，随访1年GnRH-a组骨密度不完全恢复，经联合激素反加疗法可使骨密度下降更缓慢，停药后更快恢复正常。
