Clinical data of 365 patients with type 2 diabetes admitted from December 2010 to May 2011 were retrospectively analyzed,including 130 cases with fatty liver and 235 non-fatty liver cases.There were no differences in gender,age,disease course between two groups (P ＞ 0.05). BMI,glycated hemoglobin (HbAlc),blood pressure,TC,TG,LDL-C,large vessels complications and microvascular complications rate in fatty liver group were significantly higher than those in non-fatty liver group ( all P ＜0.01 ),while there was no difference in rate of peripheral neuropathy (P ＞ 0.05 ).The results indicate that blood glucose,blood pressure,BMI,abnormal blood lipid and chronic complications were closely related to type 2 diabetics with fatty liver.

OBJECTIVE:To observe the efficacy and safety of aspirin combined with Dieda huayu powder in the prevention of deep vain thrombus (DVT) after great saphenous varicose vein surgery. METHODS:280 patients with great saphenous vein sur-gery were randomlt divided into control group and observation group. control group was given Aspirin enteric-coated tablet 100 mg breakfast in the next day of surgery,once a day;observation group was additionally given Diedahuayu powder 2 g to fumigate feet and non-operation place on ill leg in the next day of surgery. 7 d was a treatment course. The incidence of prothrombin time(PT), activated partial thromboplastin time(APTT),fibrinogen(Fg),platelet count and the incidence of DVT and adverse reactions af-ter surgery before and after surgery in 2 groups were observed. RESULTS:The incidence of DVT in observation group was signifi-cantly lower than control group,the difference was statistically significant(P<0.05). After surgery,the PT,APTT and Fg in 2 groups were significantly higher than before,and observation group was higher than control group,platelet count was significantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05);there was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Aspirin combined with Dieda huayu powder can more effectively prevent the DVT after great saphenous varicose vein surgery than only as-pirin,inhibit coagulation,with similar safety.

Objective To investigate the correlation between fasting plasma glucose(FPG)and body mass index(BMI)among examination groups in Baoji area.Methods 55 328 cases of medical examination were measured height,weight and calculated BMI,then these were detected FPG,the test results were analyzed by statistics.Results The levels of FPG and BMI were significant differences between different gender groups and different age groups;Male and female with abnormal FPG detec-tion rates were 9.90%,5.50%;FPG abnormal detection rate of male higher than female (χ2=335.47,P<0.005).The sub-j ects were divided into four groups according to their BMI:low-weight,normal,overweight and obesity.The relevance ratio of 4 groups with abnormal FPG were 2.71%,5.93%,11.65% and 13.75%,with diabetes were 1.38%,3.18%,6.02% and 6.39%,with impaired fasting glucose (IFG)were 0.8%,2.75%,5.64% and 7.37%.The detection rate of abnormal FPG, IFG and DM detection rate increased with increasing BMI levels (P<0.005).Conclusion The levels of FPG was upward trend with increasing BMI,increased prevalence of diabetes in overweight and obese people.The middle-aged population is the focus of monitoring and intervention of obesity.Control BMI is an effective measure to reduce the occurrence of diabetes.

Objective To observe the impact of pulse pressure (PP) and blood pressure (BP) circadian rhythm abnormality of aged hypertension patients on carotid atherosclerosis. Methods One hundred and fifty cases of elderly patients with essential hypertension based on 24 h ambulatory blood test results, according to the circadian blood pressure rates were divided into two groups,<10% in the non-dipper type hypertension group (72 cases),≥10%in the dipper type hypertension group (78 cases). Carotid ultrasound was performed to detect the extent, nature and classification of atherosclerotic plaques. The detection rate of carotid artery plaque in patients with hypertension was calculated based on their pulse pressure levels:≤60 mmHg (1 mmHg=0.133 kPa), 61~89 mmHg, ≥90 mmHg. Results Ultrasonography showed 61 cases of carotid artery plaques in the dipper type hypertension group, 20 cases were located bilaterally, 15 cases were in the right, 26 cases were in the left, the detection rate of plaque was 78%(61/78). Ultrasonography showed 68 cases of carotid artery plaques in the non-dipper type hypertension group, 38 cases were located bilaterally, 14 cases were in the right, 16 cases were in the left, the detection rate of plaque was 94%(68/72). The detection rate of plaque in the dipper type hypertension group was less than that in the non-dipper type hypertension group, the difference was statistically significant (χ2=8.07, P<0.01). There were 30 cases of hard plaque,13 cases of soft plaque, 8 cases of mixed plaque, and the plaques graded as 0, 1, 2, 3 were 17, 33, 13, 15 cases in dipper type hypertension group. There were 12 cases of hard plaque, 24 cases of soft plaque, 32 cases of mixed plaque, and the plques graded as 0, 1, 2, 3 were 6, 8, 25, 33 cases in non-dipper type hypertension group. The difference was statistically signiifcant (χ2=5.29, 8.75, both P < 0.01). Forty three patients with pulse pressure≤60 mmHg, the plaque detection rate was 72%(30/43);the pulse pressure of 65 cases was 61~89 mmHg, the plaque detection rate was 88%(57/65);42 cases with vein pressure ≥ 90 mmHg, the plaque detection rate was 98%(41/42). The difference was statistically signiifcant (χ2=11.65, P=0.00). Conclusion Pulse pressure increased and BP circadian rhythm abnormality are risk factors for the formation of carotid atherosclerosis.

Objective To explore the formula of predicting the maximum heart rate (HRmax) of college students in China from age,and examine its validity.Methods One hundred and one students (aged 20.9 ± 1.52 years) were recruited to undergo the VO2max test,and the HRmax was acquired after they finished the graded exercise test (GXT).The predicted value was also obtained according to the formulae of the age-predicted Hrmax:205.8-0.685 × age,206.9-0.67 × age and 210-0.66 × age.Results According to the paired t-test and one-way analysis of the variance,it was found that significant differences were observed between the measured HRmax and all the predicted values except the one got according to the formula of 210-0.66×Age.Through the method of Bland-Aitman plot,the predicted value of 210-0.66×age was more consistent with the measured value.Conclusion The 210-0.66×age equation owns the acceptable level of prediction error,and is the most suitable one of the four equations to predict the HRmax of college students in China.

Objective To assess the human β-defensin-2 ( hBD2 ) gene therapeutic efficacy in a rat urinary tract infection (UTI) model via intravesical liposome-mediated gene transfer.Methods Fifty-six female Wistar rats (class SPF) weighting 1 80 -220 were randomly divided into an experiment group and a control group ( each n =28 ).The animals were administered either 250 μl recombinant pCAGG-hBD2 or control vector pCAGG intravesically.After 48 h,rats in both groups were infected via intravesical inoculation with 200 μl of the bacterial suspension of UTI89 ( 1 × 108 CFU/ml).The rats were sacrificed at 4,24,48,and 72 h post-inoculation.The bladders were aseptically removed and bisected.One half was fixed in neutral buffered formalin for histological analysis.The remaining half-bladders were homogenized and titered for surviving bacteria.The clean-catch urine sample from each rat was collected in sterile before they were killed for bacterial titers determined and WBC counted.Results Numbers of bacterial colony-forming unit in urine and bladders from hBD2 gene treated UTI rats were significantly lower than those from the control vector administered UTI rats at 24,36,and 72 h after infection ( P ＜ 0.05 ).The amount of WBC in urine was significantly less in the defensin group than in the control group.In addition,in vivo expression of hBD2 could reduce mucosa damage,interstitium edema and inflammatory cells infiltration in UTI animals.Conclusions The successful inhibition of UTI progression could be obtained with hBD2 gene therapy.Recombinant beta-defensin-2 could kill UTI89 in vivo and suppress the subsequent infection-induced inflammatory responses.

Objective To explore the effect of aerobic exercise on cardiac function,heart rate recovery and the quality of life of elderly heart disease patients.Methods One hundred senile heart disease patients were studied.They were randomly divided into a control group and an observation group,with 50 in each group.Both groups were provided with the conventional anti-platelet aggregation treatment,dilation of blood vessels and control of blood pressure.The observation group was also given individualized aerobic exercise training.At the outset and after 3 months the cardiac function and heart rate recovery of both groups were observed,and their quality of life was evaluated using the SF-36 life quality scale.Results After the treatment,the average left ventricular ejection fraction of those in the observation group was significantly better than before the treatment,and significantly better than the average among the controls.The average 6-minute walking test time and average maximum oxygen uptake in the observation group were also significantly better than before the treatment and significantly better than among the controls.The average peak heart rate and HRR1 in the observation group had increased significantly,and significantly more than those of the control group.The average total SF-36 score in the observation group was also significantly higher.Conclusion Individualized aerobic exercise can significantly improve cardiac function and promote heart rate recovery in elderly patients with heart disease,which is of clinical value for improving their quality of life.
