Chinese Journal of Primary Medicine and Pharmacy 2017;24(3):431-434
Objective To study the effect of atorvastatin on the levels of high sensitive C-reactive protein (hs-CRP)in coronary heart disease(CHD)patients with different Gensini score.Methods 120 cases of CHD from March 201 1 to September 2015 in our hospital were selected as the research subjects.According to the different Gensini scores,they were divided into group A (Gensini score <40 ),group B (Gensini score 40 -60 ),group C (Gensini score 60 -80 ),group D (Gensini score >80 ),with 30 patients in each group.All patients were given atorvastatin treatment,the therapeutic effect of the four groups,the total cholesterol(TC),three glycerol(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL -C)and hs -CRP levels after treatment were compared.Results After treatment,the lower the Gensini score,the better curative effect,four groups had statistically significant difference in the therapeutic effects(P<0.05),and the total effective rates of group A,B, C and D were 96.7%,86.7%,76.6%,56.7%.After treatment,the TG,TC,HDL-C,LDL-C in four groups were improved,A group improved significantly better than the B group,B group improved better than those of C group,C group improved better than those of D group,the differences were statistically significant(F=6.253,6.258,5.856, 6.259,all P<0.05).After treatment,the levels of hs-CRP in group A,B,C and D were (8.2 ±3.9)mg/L,(11.9 ± 6.9)mg/L,(19.2 ±9.3)mg/L,(24.5 ±11.6)mg/L,the hs-CRP levels of four groups were lower,hs-CRP level after treatment in group A was lower than that of B,C,D groups;and hs-CRP level after treatment in group B was lower than that of group C,D;hs-CRP level of C group after treatment was lower than that of group D.The differ-ences were statistically significant(t=12.651,9.185,4.982,3.030,all P<0.05).Conclusion The level of serum hs-CRP in patients with CHD is higher,and the level of hs-CRP is positively correlated with the Gensini score.
4.Study on effect of naringenin in inhibiting migration and invasion of breast cancer cells and its molecular mechanism.
China Journal of Chinese Materia Medica 2015;40(6):1144-1150
OBJECTIVETo study the effect of nadroparin in the migration of breast cancer cells MDA-MB-231 and its action mechanism.
METHODThe MTT test was adopted to observe the effect of different concentrations of naringenin on the growth capacity of breast cancer cells MDA-MB-231. Wound healing and transwell experiment analysis were conducted to detect the effect of naringenin on the migration of breast cancer cells MDA-MB-231. Western blotting was adopted to investigate the effect of naringenin on protein expressions of MDA-MB-231 cell Integrin β3, β1 and matrix metalloproteinase MMP-2 and MMP-9. The computer virtual docking technique was used to evaluate the combining capacity of naringenin and Integrin β3 in vitro.
RESULTNaringenin inhibited the migration of MDA-MB-231 cells in a dose-dependent manner. In wound healing and transwell experiments, with the increase in the concentration of naringenin, the number of migrant MDA-MB-231 cells and the invasion capacity of breast cancer cells decreased. Naringenin could inhibit the protein expression of Integrin β3 in a dose-dependent manner, but with unobvious effect on expression of Integrin β1. Besides, naringenin could significantly inhibit the protein expressions of MMP-2 and MMP-9. The results of the computer virtual docking showed a negative value in the combining capacity between naringenin and Integrin β3, indicating the high affinity between them.
CONCLUSIONNaringenin can inhibit the growth capacity of breast cancer cells MDA-MB-231 and block the migration and invasion of breast cancer cells MDA-MB-231. Its mechanism is to down-regulate MMP-2 and MMP-9 expressions after combining with Integrin β3.

9.Clinical analysis on arthroscopic treatment of osteoarthritis of the knee
Orthopedic Journal of China 2006;0(11):-
[Objective]To evaluate the therapeutic effect of arthroscopic treatment for osteoarthritis of the knee,and explore the factors related to clinical outcome. [Methods]Three hundred and sixty-two patients with knee osteoarthritis were treated by arthroscopic surgery in the 88th hospital from May 2000 to November 2007. Of them,124 patients were followed-up completely. Quantified clinical data were input into computer and analyzed statistically by SPSS 16.0 software. Lysholm score was used to evaluate the therapeutic effect. Lysholm scores before surgery and at follow up were compared with paired t test. Patients were divided into different subgroups according to sex,locking,X -ray grade,arthroscopic grade and surgical methods. Lysholm scores at the final follow up of different subgroups were compared with variance analysis. The factors related to operation outcome were explored by using multiple stepwise linear regression analysis.[Results]One hundred and twenty-four patients were followed up from 7 to 96 months with an average of 39.6 months. Preoperative Lysholm score was (46.10?2.80),the score at follow up was (70.69+2.90),there was significant difference between preoperative score and at follow up (t=9.362,P0.05). The difference was significant between groups whether locking or not (F=10.654,P
