Preliminary study on immunotoxin for the prevention of Schistosomiasis japonica

To investigate the effects of immunotoxin (bio-missile) on the prevention of schistosomiasis. The monoclonal antibody NP11-4, located in out-layer membrane of adult worm, membrane of cercariae, membrane of schistosomula, shell of egg and membrane of miracidium in egg, was combined with artesunate (produced by Guilin Pharmaceutical Factory of China) by chemical method to fabricate immunotoxin.     

Autologous peripheral blood stem cell transplantation in the patients with hematologic malignancies and solid tumors

Objective To evaluate the long-term therapeutic effects of autologous peripheral blood st em cell transplantation (auto-PBSCT) on the treatment of hematological and soli d tumors. Methods Fifty-one patients were recruited in this auto-PBSCT study, in which several p otentially important parameters were studied including the optimal time for stem cell co llection, the dose of stem cell reinfusion, the time of hematopoietic reconsti tution, the disease free survival (DFS) and overall survival (OS), complication s related to transplantation, and maintenance chemotherapy after auto-PBSCT. Results After APBSCT, 3-year and 5-year survival rates of NHL were 83.3%; those of AM L were 74.7%; those of MM were 37.9% and 19%; those of ALL were 40% and 0% res pectively. Hematopoietic reconstitution was greatly promoted by granulocyte col ony stimulating factor (G-CSF). The mean time for patients’ neutrophil to reco ver up to >0.5×10(9) /L after APBSCT was 11.14 days in the group of the patien ts receiving G-CSF in contrast to 17.6 days in the group receiving no G-CSF. The most common complications of transplantation were fever, liver dysfunction and hypokalaemia, which were curable. No death was due to transplantation related complications.Conclusion Comparing with conventional chemotherapy, our study suggests that auto-PBSCT i s a very important therapeutic option that can significantly improve the prognos is in the patients with hematological and solid tumors, especially in the patien ts with AML and NHL.

神阙穴敷贴对原发性骨质疏松症骨钙素的影响

目的　观察神阙穴贴补血益精透皮贴对原发性骨质疏松症骨钙素 (BGP)的影响。方法　选择原发性骨质疏松症患者130名 ,分神阙穴贴药组 (补血益精穴位透皮贴剂 )、西药组 (羟乙磷酸钠片 )、中药组 (补血益精药丸 )、空白对照组。结果和结论　穴位敷贴组能显著提高骨钙素 (7.69± 1.65 )。穴位敷贴组与中药组 (7.82± 0 .99)和西药对照组 (7.13± 0 .89)对原发性骨质疏松症的骨钙素调整作用基本一致 (P>0 .0 5 )。     

一氧化氮与光化学法诱导大鼠脑缺血早期损伤的关系和绞股蓝总皂苷对脑缺血损伤的保护作用

目的：探讨一氧化氮(NO)与光化学法诱导大鼠脑缺血早期损伤的关系和绞股蓝总皂苷(Gyp)对脑缺血损伤的保护作用。方法：应用光化学法诱导大鼠大脑中动脉栓塞(MCAO)模型，观察氧合血红蛋白(OHb)和Gyp对MCAO后脑梗死范围，脑组织含水量、NO及超氧化歧化酶(SOD)、脂质过氧化产物TBARS含量的影响。结果：MCAO6h可导致大鼠局部脑组织明显梗死、脑水肿，同时SOD活力下降，TBARS含量升高，NO释放减少。OHb能进一步强化上述改变而Gyp能逆转上述变化。结论：脑内过氧化反应水平增高导致早期NO含量减少是脑缺血形成的重要原因之一，Gyp可通过影响脑缺血损伤早期脑内NO水平发挥对脑缺血的保护作用。
