[Objective]To study whether Cervus and Cucumis Polypeptide(CCP ,Lugua polypeptide) can treat osteoporosis or not. [Methods]Forty 4-month-old female SD rats were randomized into four groups(10 in each group) ,including SHAM,0VX, OVX+CCP1 and OVX+CCP2 groups. Male rats in OVX groups take the ovariectomized surgery. Since the 13th week, rats in groups A and B got 0.9% physiological saline injection once in a day, group C was treated with CCP 0.4mL/(kg·d)injection and group D treated with CCP0.8mL/(kg·d) injection once one day. Twelve weeks later, al rats were sacrificed for obtaining specimen. Took right femurs, measured the bone biomechanical properties. [Results ]After 12 weeks since injection, the biomechanical property of right femurs in group OVX was significantly lower than that of the SHAM group( P<0.01); parameters such as maximum load and elastic load in group OVX+CCP1 and OVX+CCP2 were higher than that of group OVX(P<0.05), but lower than that of group SHAM(P<0.05). The distinction of the above parameters was significant( P<0.05)between group OVX+CCP1 and OVX+CCP2. [Conclusion]1.CCP can significantly im-prove the bone internal biomechanical properties in ovariectomized(OVX) rats, so it has function to treat osteoporosis caused by drop in estrogen level. There are differences of bone biomechanical properties aspects when treated with different dosage of CCP, which shows the tendency of dose-dependent effect. So we can conclude that CCP may have dose-dependent effect.

Objective To investigate the effects of heat preconditioning (HP) on the expression of protein kinase C (PKC) δ and PKCε in the myocardium of overload exercise rats. Methods 25 male three-month-old Sprague-Dauley rats were divided into control group (n=5), exercise group (n=10) and HP group (n=10). The expression of PKCδ and PKCε in the myocardium was detected with immunohistochemistry, real-time PCR and Western blotting 8 weeks after overload exercise. Results The expression of PKCδ significantly increased in the exercise group compared with the control group and the HP group (P<0.05). In another hand, PCR and immunohistochemistry showed the expression of PKCε in the exercise group decreased compared with the control group and the HP group (P<0.05), but it was not significantly different among the groups using Western blotting (P>0.05). Conclusion PKCs may play an important role in the HP-induced cardio-protection during overload exercise.

Objective To learn the effect on carcinoma xenograft in nude mice by inhibiting human papillomavirus 16(HPV16) E6 gene expression in CaSki cell. Methods The recombinant plasmids expressing HPV16 E6 small interference RNA (siRNA) were transfected into CaSki cell. The cells expressing recombinant plasmid was screened out with G418. The expression of E6 mRNA was determined by RT-PCR. The cells were inoculated into BALB/c nude mice subcutaneouly and the growth of the xenograft carcinoma was observed. After the pGensil-CH2 recombinant was injected into the carcinoma, the growth of carcinoma and pathological changes of carcinoma were observed. Results The CaSki cell expressing E6 siRNA was obtained, and HPV16 E6 mRNA expression in CaSki cell was down-regulated. The oncogenicity of the CaSki cell expressing E6 siRNA was degraded, the inhibition rate was up to 71.4% as compared with that of control group. The growth of tumor in nude mice was inhibited after the E6 siRNA plasmids were injected into the nude mice. The volume and weight of the tumor treated by siRNA were smaller than that of control group significantly. More necrotic area and less cell division phase were observed under light microscope in the E6 siRNA treated tumor. Conclusion The oncogenicity of the CaSki cell was degraded after silencing HPV16 E6 gene in CaSki cell by E6 siRNA.

During the process of growth, harvesting, transportation, processing and storage, Chinese herbal medicines (CHMs) can be easily contaminated by fungi and their metabolites like mycotoxins, which not only express negative effects on the quality and safety of CHMs and their processed products, but also pose great threats to human health. Now, some chemical synthetic fungicides have been frequently used to control the growth of fungi and accumulation of mycotoxins in the preservation of CHMs. However, the concentration and type of chemical fungicides allowed for postharvest application are restricted due to the disadvantages of their high residual toxicity, long degradation period and pollution to the environment and so on. Therefore, it is critical to research and develop some highly effective, safe and non-toxic, natural, environment-friendly fungistatic agents from plants to prevent CHMs from being contaminated by fungi and mycotoxins. The paper reviews mycotoxins and their harmfulness, the effective compounds of fungistatic plants as well as the antifungal mechanism to provide scientific evidences for developing novel and effective fungistatic agents plants. Then, the application prospect of fungistatic agents from plants in the preservation of CHMs was discussed.

Objective To study the in vitro effects of different doses and different kinds of LMWH on CR, and to determine whether the CR test could be used to monitor LMWH. Methods The CR value was measured with different reagents ( glass beads, celite and kaolin ) in blood samples from twenty volunteer donors, which were spiked with increasing concentration of LMWH ( dalteparin, 0-1.8 IU/ml ). Then the CR test was performed again on the same blood samples spiked with the same concentration ( 0. 8 IU/ml ) but different LMWH ( dalteparin, enoxaparin and nadroparin ). Regression analysis was performed to establish a regression equation from corresponding LMWH levels. Results With the increasing of dalteparin dose, CR values were reduced gradually for all three reagents. When the concentration of dalteparin was 0-1.8 IU/ml,the value of CR was 20. 0-4. 5 IU/min for glass beads, 26. 1-6.6 IU/min for celite and 27. 2-7. 5 IU/min for kaolin. An exponential relationship was observed between the CR value and dalteparin concentration for three reagents( R2 = -0.796, -0.884, -0.921 ,P ＜0.01 ). All three kinds of LMWH with the same concentration (0.8 IU/ml ) induced a different change in CR. The value of CR was 7.4 IU/min with dalteparin,8. 5 IU/min with enoxaparin and 8.5 IU/min with nadroparin. Compared with the control group ( CR was 17.6 IU/min ), three kinds of LMWH had statistical significance ( t = 18.45, 12. 33, 14. 93, P ＜ 0.01 ).Compared with the enoxaparin and nadroparin, dalteparin induced a higher CR value ( t = 2. 552,2. 924,P＜0. 05 ). Conclusions There is an exponential relationship between CR value and dalteparin concentration for three reagents. Three kinds of LMWH can significantly reduce the value of CR. CR test can be used to monitor the anticoagulant effect of LMWH.
