Abrin is isolated from abrin seeds (Aburs precatoriusL.), which is a kind of cytotoxic protein. This article reviewed the anticancer effect and mechanisms of Abrin from five aspects in several years, which were the molecular structure and toxicity of Abrin, the characteristics of Abrin in anticancer effect, the role of Abrin in inhibiting cancer cell proliferation, the mechanisms of Abrin induced apoptosis of cancer cells, the anticancer mechanisms of Abrin in enhancing immune function. And the application prospect of Abrin immunotoxin targeted therapy and nano preparation will be expounded in this article. It will be helpful to further research about application on Abrin. It will provide the scientific basis for discovering new drug targets of cancer.

Objective To study the mechanism of Danshi Qing Tablet (DQT) in treating cho lelithiasis. Methods Sixty guinea pigs were randomly allocated to five groups : Group A (normal control), Group B (model control), Group C (treated with low d osage of DQT), Group D (treated with high dosage of DQT) and Group E (treated w ith Xiaorong Gandanjieshi Tablet). Guinea pig models of cholelithiasis were esta blished by subcutaneous injection of lincomycin. Results After six weeks of treatment, the content of the bile acid (BA) was higher and the content of tota l bil irubin TBIL and Ca 2+ was lower in Group C and Group D than those in Group B. The ga llstone formation rate in Group D was 27.27%, which was lower t han that in Group B (80%), the difference being significant (P

Objective.To probe into the influence of Jiannao Anshen Capsule of Miao medicine on the behavioral performance,content of cytokine interleukin-1 (IL-1),neuroendocrine hormone melatonin (MT) and monoamine neurotransmitter 5-hydroxytryptamine (5-HT) of rats with sleep deprival.Methods All of the 60 rats were evenly and randomly divided into 5 groups:the normal control group,model control group,estazolam group,Zaoren Anshen group,and Jiannao Anshen of Miao medicine group,respectively.Every group had 12 rats.Sleep deprivation rat model was established by intraperitoneal injection of para-chlorophenyla lanice (PCPA).After successful modeling,the rats were intragastrically administrated with corresponding medicines.The contents of serum 5-HT,IL-1 and MT and the contents of 5-HT,MT in brain tissue were determined.Results Behavioral score,the contents of 5-HT,MT and IL-1 in serum and the contents of 5-HT,MT in brain tissue in insomnia rats caused by PCPA were significantly decreased as compared with normal control group (P ＜ 0.05).In the Jiannao Anshen group,estazolam group and Zaoren Anshen group,the behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were significantly increased as compared with model control group (P ＜ 0.05).The behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were not statistically significant different among Jiannao Anshen group,estazolam group and Zaoren Anshen group (P ＞ 0.05).Conclusion Jiannao Anshen capsule of Miao medicine could obviously improve the sleep quality of rats with sleep deprival.The mechanism may be related to improving the content of IL-1,MT and 5-HT.

2 000 mIU/ml,combined use of mifepristone(100 mg,twice daily,for 3 days) was employed. Results The treatment succeeded in 28 patients,with a success rate of 87.5%.Acute lower abdominal pain occurred in 4 patients and laparoscopic salpingectomies were carried out.The serum ?-hCG levels decreased by 23%~35% at 3 days after injection,by 38%~62% at 1 week,and to normal levels(≤6.1 mIU/ml) at 2~4 weeks.The mass completed subsided at 30～55 days after injection. Conclusions Transvaginal ultrasound guided methotrexate injection for the management of unruptured early tubal pregnancy is simple,safe, and effective.Further investigations should be carried out in respect of the recovery of tubal anatomy and physiological functions.

Objective To evaluate the diagnostic value of hysteroscopy in comparison with hysteros- alpingography(HSG) in the detection of intrauterine abnormalities in infertile patients.Methods 52 patients(ob- serving group) with filling defects under HSG received hysteroscopy,and the remaining 22 patients (contrasting group) with normal hysterosalpingographic findings also received hysteroscopy with their consent.Results In- trauterine abnormalities in observing group and contrasting group confirmed by hysteroscopy were 78.8 % and 9.1% respectively,and there was statistical significance(P

Objective To analyze the characteristics and hepatotropism of this negative element HBVnt453-250 sequence.Methods pHBv453-250,pHBV250-453.plucHBV453-250 and plucHBV250-453 were constructed,with luciferase and enhanced green fluorecence protein(EGFP)gene as the reporter gene,respectively.After transfection of HepG2 cells with these plasmids,luciferase assays,real-time PCR and western blot assays were used to detect the gene transcription and expression level.The SV40 promoter of pGL3 control and pHBV453-250 were replaced by the cytomegalovirus early promoter,resulting in plasmids pCMVcontrol(luc)and pCMV453-250(luc).Results Compared with pHBV453-250,the mutant plasmids.with the inhibitory element inserted in difierent site or inverted orientation.exerted similar downregulation of Juciferase gene transcription and expression.Western blot analysis demonstrated the similar repression when EGFP was used as the reporter gene.By transfeeted to HepG2 cell line,the plasmid pCMV453-250(1UC)could reduce lneiferase activity(36.56%)compared with pCMLcontrol(luc).When the plasmids plueHBV453-250 and plucHBV250-453 were transfected to non-liver cell lines(A549,HeLa),luciferase gene was expressed weakly,compared with that of pGL3control(P＜0.05).Conclusion The inhibitory effect of HBVnt453-250 sequence acted in both orientation-and position-independent manners,and had no promoter selectivity and funotioned in hepatocyte-independent manner.
