AIM:To separate and purify a new anti-clotting protein component(ACPF-7221)from the venom of Agkistrodon. The acute toxicity experiment of ACPF-7221 and the death rate were studied and the LD50 and 95% confidence interval were determined in mice. METHODS: The venom of Agkistrodon was separated and purified using ion-exchange chromatography of DEAE-Sepharose Fast Flow, molecular sieve filtration through Sephadex G75, SP-Sepharose Fast Flow and molecular sieve filtration through Sephadex G50, the anticoagulation components were recalled using activated partial thromboplastin time (APTT) activity assay. ACPF-7221 was given to mice by intravenous injection,and the dosage was determined according to the body weight of mice. The LD50 and 95% confidence were calculated by the death outcome. RESULTS: ACPF-7221 was separated and purified,which was a trimer consisted of three kinds of protein and their relative molecular mass were 25000, 30000 and 50000,and the protein level was 65%. The LD50 of ACPF-7221 was 7.848 mg/kg, and its 95% confident interval was 7.353-8.375 mg/kg. CONCLUSION: A new anti-clotting protein component ACPF-7221 was extracted from the venom of Agkistrodon by ion-exchange chromatography,which is a trimer consisted of three kinds of protein. The critical orga of acute toxicity is lung, empsyxis asphyxia deduces death.

The function of cellular membrane receptor has been paid more attention in many dieases.Integrin is one of them.The major function of integrin is maintaining the proper structure of tissues by organization of cell-cell and cell-extracelluar matrix tethering.The initiation and prolongation of many diseases are promoted by these receptors.Disintegrin is one important component of the snake venom.It inhibit the adhesive attraction of integrin particularly.This review summarizes the types and the biological activities of snake venom disintegrins,as well as discusses there potential clinical application of the study,such as anti-tumor,anticoagulation,and various human diseases.

Objective To explore the influence of ROI size on the diagnostic performance of shear wave elstography (SWE) of breast masses.Methods A total of 225 consecutive patients with 239 solid breast masses underwent SWE before surgery,and then quantitative SWE parameters,including the maximum stiffness (Emax),mean stiffness (Emean),ratio of stiffness of the mass to stiffness of surrounding fat (Eratio) and standard deviation (SD),were measured by two methods,one method was using larger ROI to include the largest part of a mass,and the other was placing fixed ROI=2 mm over the stiffest part of the lesion to measure.The diagnostic performance of the two methods were evaluated by ROC curve,and the cut-off value,sensitivity and specificity of each SWE parameter were obtained.Results There were no statistically significant differences between the performance of Emax,Emean and SD from the two different methods (all P＞ 0.05),the performance of Eratio of the two methods showed significant difference (P=0.046).The significantly higher specificity of Emax and Emean in the larger ROI were found,and the significantly higher sensitivity of SD and Eratio in the ROI=2 mm was found.Furthermore,the diagnostic performance of combination of SWE and BI-RADS were not greatly affected by the ROI size,the difference had no statistical significance (all P＞0.05).Conclusion The ROI size only affects the diagnostic performance of Eratio,and donot affect the diagnostic performance of the quantitative SWE parameters (Emax,Emean,SD) and combination of SWE and BI-RADS.

Neoadjuvant chemotherapy is one of the common means in multidisciplinary treatment of locally advanced breast cancer,with anthracyclines and taxanes as main chemotherapeutic drugs.In recent years,molecular target agents have significantly improved the efficacy of chemotherapy,as well as have provided more choices and ideas for clinical treatment.Currently,the widely studied molecular targeted drugs include trastuzumab,lapatinib,pertuzumab,T-DM1 and bevacizumab.

Snake venoms are complex mixtures containing many different biologically active applications in the field of cancer research. In this paper, not only unpurified fraction, but also highly purified snake venoms are discussed,such as rhodostomin, acutobin, agkistrodon halys antithrombotic enzyme, batroxobin. The review mainly introduced the inhibitory effects of snake venoms on tumer metastasis.

The syndrome of insulin-dependent diabetes mellitus(IDDM)includes not only abnor-mal glucose metabolism but also specific microvascular complications that include nephropathy,retinopathy and neuropathy.In the short term,improvement in the quality of life and possible prevention of further morbidity associated with diabetes makes pancreas trans-plantation an important therapeutic option,particularly when combined with a kidney trans-plant,in appropriately selected diabetic patients.The focus of the early management of the pancreas transplant recipient is the prevention of acute rejection.In this article we review the methods for clinical diagnosis of the early acute rejection due to pancreas transplanta-tion.

OBJECTIVE:To provide reference for the rational use of vancomycin in neonatal sepsis. METHODS:A retrospec-tive survey was performed for newborns with neonatal sepsis in our hospital from Sept. 1st in 2011 to Sept. 1st in 2012,and the pathogenic examination results,bacterial resistance and use of vancomycin were analyzed and summarized. RESULTS:Totally 317 strains of pathogens were detected in 202 cases,including 147 strains of G+ bacteria(46.4%),88 strains of fungus(27.7%)and 82 strains of G- bacteria (25.9%). Coagulase-negative staphylococcus was the main pathogens. The use rate of vancomycin was 47.0%(95 cases),and the drug selections were all based on susceptibility,with most of two-drug combination(68 cases). No se-vere adverse reactions were found. CONCLUSIONS:Coagulase-negative staphylococcus is severe and has multi-drug resistance in the cases of neonatal sepsis in our hospital. While,the use of vancomycin is basically rational. However,the clinical use of vanco-mycin should be more cautious to prevent the generation of vancomycin-resistant strains.

0.05),but the cross reaction rate of recombinant Ts21 protein with sera from mice infected with T2,T3,T4 and T7 was considerably lower than that of ES antigens(?2=17.069,P

Objective To observe the influence of electroacupuncure(EA) at different therapeutic time windows on the effects of inosine on neuronal apoptosis and expression of heat-shock-proteins-70 (HSP70)after focal cerebral ischemic reperfusion injury (CIRI) in rats.Methods The model was established by ligation of the artery for 2 hour.EA was delivered to “baihui” and “dazhui” through acupuncture needles 0.5 hr,2 hr,6 hr and 12 hr respectively following MCAO.The expression level of HSP70 and the number of apoptotic cells were examined by immunohistochemical technique and TUNEL,comparing the average optical density of HSP70 and the number of apoptotic positive cells of cortex penumbra and hippocampus CA1 area in rat brain.Results Compared with the model group,the average optical density of HSP70 in every EA group was increased in apoptotic positive cells of cortex penumbra and hippocampus CA1 area 0.5 h (89.98± 6.55),(128.73 ± 8.03),2 h (90.96±6.38),(132.25±8.78),6 h (93.71±6.12),(132.58±7.04),12 (96.19±7.30),(133.57±6.19)and the number of apoptotic positive cells of cortex penumbra in every EA group was decreased 0.5 h (1.80±0.84),2 h (3.40± 1.14),6 h (5.00± 1.00),12 h (5.00±2.45).The number of apoptotic cells of hippocampus CA1 area was decreased just in the EA group of 0.5 h (1.60± 1.89).Conclusion EA could increase the expression level of HSP70 and at the same time decrease the number of apoptotic cells,EA plays an important part in protecting the neuronal cells of brain after focal cerebral ischemic reperfusion injury.The acupuncture treatment should be taken as far as early.
