Objective To investigate the clinical effects and significance of different-dose atorvastatin on soluble CD105(sCD105),high sensitive-C reactive protein(hs-CRP)and the parameters of heart rate turbulence in patients with acute coronary syndrome(ACS). Methods One hundred and six ACS patients were divided into three groups by random digits table: control group(30 patients, routine treatment),treatment group Ⅰ(38 patients, routine treatment + atorvastatin 20 mg), and treatment group Ⅱ(38patients, routine treatment + atorvastatin 40 mg). All patients were treated for 4 weeks. The levels of serum sCD105,hs-CRP,and the parameters of heart rate turbulence before and after treatment. Results Before treatment, the levels of turbulence onset(TO), turbulence slope(TS),sCD105 and hs-CRP in three groups had no significant difference(P ＞ 0.05). After treatment, TO,sCD105 and hs-CRP decreased significantly,and TS increased significantly(P＜ 0.05 or ＜ 0.01). The change amplitude of treatment group Ⅱ was the most obvious, and the levels of above mentioned index showed significantly difference compared with that of treatment group Ⅰ[TO:(0.22 ±0.18)% vs.(0.66 ± 0.23)%;TS:(6.22 ±0.83)ms/RR interval(RRI)vs.(3.90 ±0.73)ms/RRI;sCD105:(1.65 ±0.43)mg/L vs.(2.92 ±0.50)mg/L;hs-CRP:(1.68 ±0.55)mg/L vs.(2.08±0.61)mg/L](P ＜0.01). Correlation analysis showed the levels of sCD105 and hs-CRP had significantly positive correlation with TO(P ＜ 0.01)and had negative correlation with TS(P ＜ 0.01).Conclusions The atorvastatin treatment in patients with ACS may stabilize coronary vascular endothelial cells and atherosclerotic plaque, and improve autonomic nerve function. Larger doses of atorvastatin may get more benefit.

Objective To evaluate the efficacy and safety of levosimendan applied in patients with chronic heart failure combined with acute ST -elevation myocardium after direct percutaneous coronary intervention (PCI). Methods Using the random number table method,95 patients with heart failure combined with acute ST -elevation myocardium after direct PCI were randomly divided into two groups:the general treatment group and the levosimendan group.The levels of serum NT -proBNP,LVSD,LVEF before and after 24h,one week treatment were examined.After the experiment,clinical assessment was performed to evaluate the efficacy and safety of levosimendan.Results The resuits of NT -proBNP,LVEF and LVSD in the general group before treatment were (5 908.1 ±33.2)ng/L, (36.7 ±4.3)% and (6.1 ±0.6)cm,while those were (3 478.5 ±19.3)ng/L,(45.0 ±6.3)%,(5.9 ±0.3)cm, (3 375.2 ±32.1)ng/L,(48.3 ±5.4)% and (5.8 ±1.1)cm after 24h and 1 week treatment.The level of serum NT-proBNP decreased,while the LVEF increased in general treatment group after 24h treatment(t =3.86,4.11,P =0.021,0.015).The same results happened after 1 week treatment(compared with before treatment,t =4.13,5.06, P =0.016,0.013,compared with 24 hours after treatment,t =3.96,4.77,P =0.021,0.015).But the level of the LVSD had no differences before and after 24h,1 week treatment(P >0.05).The results of NT -proBNP,LVEF and LVSD in the levosimendan group before treatment were (3 340.5 ±19.2)ng/L,(43.3 ±3.9)%,(5.3 ±0.7)cm, (2 938.3 ±12.8)ng/L,(52.7 ±8.2)% and (4.6 ±0.2)cm after 24h and 1 week treatment.The levels of serum NT -proBNP,LVSD decreased,while the LVEF increased in the levosimendan group after 24h,1 week treatment(t =6.07,6.49,5.73,P =0.010,0.008,0.011.t =6.55,7.05,5.33,P =0.009,0.007,0.012).Compared with the general treatment group,the levels of serum NT -proBNP,LVEF showed no differences(all P >0.05),but the level of the LVSD decreased after 24h treatment(t =4.84,P =0.015)in the levosimendan group.The levels of serum NT -proBNP,LVSD decreased,while the LVEF increased in the levosimendan group after 1 week treatment compared with the general treatment group(t =6.60,7.01,5.40,P =0.007,0.007,0.011 ).After one week treatment,the effective and beneficial rates of the levosimendan group were 66.6% and 95.6%,while those were 59.6% and 89.5% in the general treatment group.The therapeutic effects of levosimendan group were more effective than the general treatment group after 1 week treatment(χ2 =9.72,15.63,P =0.015,0.008),but had no statistical differ-ences between the two groups after 24h treatment(P >0.05).There was no statistical differences between the two groups in the rate of adverse reactions.Conclusion Levosimendan has very favorable efficacy and safety for patients with chronic heart failure combined with acute ST -elevation myocardium infarction after direct PCI.

Purpose To investigate the expression of OTUB1 in colon cancer and the relationship between its expression and some clinicopathologic parameters. Methods Quantitative real-time PCR and immunohistochemical SP method were carried out in selected colon cancer and normal mucosa tissues. Results OTUB1 mRNA in colon cancer was 3. 5-fold higher than the normal mucosa. The expression of OTUB1 protein in the colon cancer was significantly higher than normal mucosa (P<0. 05). Moreover, its expression in normal tissues, adenoma and colon cancer showed a gradually increasing trend (P<0. 05). The higher expression of OTUB1 in colon cancer was related with tumor size, differentiation and lymph node metastasis. Conclusions OTUB1 may play an important role in co-lon cancer development.
