1.The effects of somatostatin on the proliferation of human HepG2 cells and the level of gene p16
Cancer Research and Clinic 2010;22(11):758-760
Objective To study the effect of somatostatin on the Proliferation in Human HepG2 Cells and the Level of Gene p16. Methods The cell line HepG2 were divided into 3 groups: control groupA, low concentration group B and high concentration group C. The flow cytometry (FCM) was used to detect phase distribution of the cycles and detect the expression of p16 gene by using RT-PCR. Results Human HepG2 cells affected 24 hours later by different density SST, using FCM, we discovered that the G1 cell cycles of each A group, B group, C group occupied the proportion respectively is (51.41±3.27)%, (65.43±3.41)%, (69.02±3.75)%, that the S cell cycles is (36.86±2.31)%, (20.34±2.52)%, (18.50±3.09)%, that the G2 cell cycles is (11.46±1.96)%, (14.23±3.83)%, (12.48±3.18)%. Compare to the control groupA, the G1 cell cycles of groupB and group C were increased obviously. But the S cell cycles relatively reduced. The levels of p16 gene were expressed in each group detected by RT-PCR, but B group and C group expressed obviously. Conclusion The inhibited mechanism of somatostatin for HepG2 was expressed probably by improving levels of p16.

Objective To explore the effect of Linggui Zhugan decoction on the level of serum inflammatory factors , blood lipid and oxidation with coronary heart disease (CHD).Methods 123 cases of patients diagnosed as CHD and met criterions were collected from May 2013 to February 2015 in cardiovascular department of our hospital.They were divided into two groups according to different treatment modalities, observation group and control group.General information of the two groups were comparable, The patients of two groups reveived conventional treatments such as taking aspirin enteric-coated tablets, rosuvastatin, nitrate.The patients of observation group received Linggui Zhugan Decoction on the basis of conventional treatments.The serum levels of TC, TG, LDL-C, HDL-C, TNF-α, IL-6, IL-1β, SOD, MDA were recorded before and after treatment.Results The serum levels of TC, TG, LDL-C of observation groups were lower than those of control group after treatment (P<0.05).And the serum levels of HDL-C of observation groups were higher than those of control group after treatment (P<0.05).There was significant improvement in the serum levels of TNF-α, IL-6, IL-1β, MDA and SOD of two groups after treatment than those before treatment (P<0.05).The serum levels of TNF-α, IL-6, IL-1β, MDA of observation group were lower than those of control group after treatment ( P<0.05 ) , while the SOD serum levels of observation group were higher than those of control group after treatment (P<0.05).Conclusion Linggui Zhugan decoction could significantly improve the levels of blood lipids and decrease the levels of inflammation and oxidative stress in patients of CHD with significant effect.

Objective To investigate the effect of FK506 on the expression of TNF -? mRNA in isolated liver with reperfusion. Methods After the model of isolated liver with reperfusion was set upp,the expression of TNF-? mRNA was detected with RT-PCR in different preservation time of the isolated liver. Results In FK506-treated group, expression level of TNF-? mRNA was obviously lower(P
