This article presents the design of a treadmill of comprehensive training experiment for rats. The treadmill is composed of six tracks and two of them were designed as conventional plane, two were designed to swing right and left, and two were designed to swing back and forth. The power was provided by six motors. The MSP430F149 is used as core to adjust the swing rate and the grade of electric shock. The IAR for MSP430 is used to design the software. The speed of the six tracks could be adjusted between 0 and 30 m/min. The swing tracks of back and forth can be swung for 3-25 times per minute and the swing tracks of right and left for 3-32 times. The electric shock can be divided into three levels, i. e. strong, middle, and weak level for each track. The digital comprehensive training treadmill can meet different training needs, and provide experimental data for mechanism research of some related diseases.

ObjectiveTo determine the expression of matrix metalloproteinase-2 (MMP-2),cysteine rich protein 61 (Cyr61) and CD25 in esophageal carcinoma and investigate their clinical significance.MethodThe expression of MMP-2, Cyr61 and CD25 in 68 cases of esophageal tumor tissues (esophageal carcinoma group ) and part-cancer( para-cancer group ) and 68 cases of reflux esophagitis (control group ) was detected by immunohistochemical method and the results were statistically analysed. ResultsThe positive expression rates of MMP-2,Cyr61 and CD25 were 82.35％(56/68), 73.53％(50/68) and 89.71％(61/68)respectively in esophageal carcinoma group,there were significant differences compared with those in paracancer group and control group(P ＜ 0.05) ; while there was no significantdifference between para-cancer group and control group (P ＞ 0.05 ). The positive expression rates of MMP-2, Cyr61 and CD25 in esophageal carcinoma group in different T stage, N stage and M stage all had statisticall differences (P ＜ 0.05),while there was no significant difference in different degree of differentiation (P ＞ 0.05 ). ConclusionMMP-2,Cyr61 and CD25 is highly expressed in esophageal carcinoma,there is some significance for understanding the occurrence, development and prognosis of esophageal carcinoma.

Objective To investigate the association between arterial compliance and fundus oculi arteriosclerosis in elderly people. Methods A total of 73 elderly subjects,including 61 elderly patients with fundus oculi arteriosclerosis and 12 healthy volunteers were recruited into the study.Capacitive arterial compliance(C1)and oscillatory arterial compliance(C2)were measured by DO2020 Cardiovascular Profiling Instrument.Moreover,fundus photographs were measured using Canon figure fundus camera. Results There were significant differences in systolic blood pressure(SBP),diastolic blood pressure(DBP),mean artery pressure,pulse pressure,capacitive arterial compliance (C1),and oscillatory arterial compliance(C2)between patients with fundus oculi arteriosclerosis and healthy volunteers(all P<0.05).In multiple regression analysis,the grade of fundus oculi arteriosclerosis was significantly correlated with SBP,DBP,mean artery pressure and pulse pressure (r=0.357,0.261,0.342,0.280,all P<0.05).Moreover,there were significant correlations between the grade of fundus oculi arteriosclerosis and Cl(r=-0.281,P<:0.05),and C2(r=-0.308,P<0.01). Conclusions These findings underscore the efficacy of C1 and C2 in identifying patients with fundus oculi arteriosclerosis.

Objective:To investigate the effects of rosuvastatin and lfuvastatin on patients with acute coronary syndrome (ACS) combing impaired glucose tolerance (IGT).
Methods: A total of 215 consecutive ACS patients combing IGT treated in our hospital from 2009-05 to 2011-05 were studied. The patients were randomly divided into 2 groups, Rosuvastatin group, the patients received rosuvastatin10mg/day, n=108 and Fluvastatin group, the patients received fluvastatin 40mg/day, n=107. The total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) levels before and at 6, 12, 24 months after medication, fasting blood glucose (FBG), 2-hour postprandial glucose (2hPBG) and the number of new-onset of diabetes patients were compared between 2 groups.
Results: After treatment, the TC, LDL-C levels were decreased (6, 12, 24 months) and the HDL-C level (12, 24 months), 2hPBG (24 months) were increased in both groups. Compared with Fluvastatin group, Rosuvastatin group had decreased TC and LDL-C (6, 12, 24 months), and increased LDL-C (24 months). With 6, 12, 24 months treatment, the blood lipids reached the standard were more in Rosuvastatin group than those in Fluvastatin group as 35.3%vs 26.1%, 36.4% vs 22.0%, 43.1% vs 31.8% respectively, all P<0.05. With 12 and 24 months treatment, the new-onset diabetes patients in Rosuvastatin group were 11 and 18, in Fluvastatin group were 12 and 17. With 12, 24 months treatment, FBG, 2hPBG levels and the number of new-onset diabetes patients were similar between 2 groups, P>0.05.
Conclusion: Compared with lfuvastatin, the conventional dose of rosuvastatin could better reduce the blood lipids level in ACS patients combing IGT, the effects for preventing ACS patients from IGT to diabetes were similar for both drugs.
