Objective To compare the efficacy and safety of recombinant insulin lispro and insulin lispro in the treatment of type 2 diabetes mellitus(T2DM ) .Methods Forty‐eight T2DM patients with poor blood glucose control were randomly assigned to the recombinant insulin lispro group (observation group ,n=32) and insulin lispro group (control group ,n=16) according to the ratio of 2∶1 .On the basis of injection of the recombinant insulin glargine once daily before sleep ,the two groups were given the re‐combinant insulin lispro injection or insulin lispro injection once before each meal .The period of treatment was 16 weeks .The levels of HbA1c ,2 h postprandial blood glucose(2hPG) and fasting plasma glucose(FPG) before and after treatment were measured and compared between the two groups .The adverse events were evaluated at the end of treatment .Results Forty‐four cases finished the study ,28 cases in the observation group and 16 cases in the control group .The levels of HbA1c ,FPG and 2hPG after 16‐week treatment in the two groups were decreased significantly (P<0 .05) .The decrease amplitudes of HbA1c in the observation group and the control group were (1 .55 ± 1 .50)% and(1 .06 ± 1 .30)% respectively ,which of FPG were (2 .07 ± 5 .01)mmol/L and (1 .09 ± 3 .18)mmol/L respectively ,and which of 2hPG declined (3 .28 ± 5 .71)mmol/L and(3 .60 ± 5 .89)mmol/L respectively . With HbA1c as the main evaluation index and 0 .40 as the non‐inferiority critical value ,non‐inferiority was found in the recombi‐nant insulin lispro injection as compared with the insulin lispro injection (P<0 .05) .The standard‐reaching rate of HbA1c less than 6 .50% in observation group was 14 .29% ,and which of HbA1c less than 7 .00% was 28 .57% ;in control group ,these two stand‐ard‐reaching rates were 18 .75% and 43 .75% respectively ,and there were no statistically significant differences between two groups (P>0 .05) .Conclusion The recombinant insulin lispro injection has non‐inferiority effects in the aspect of effectiveness compared with the lispro insulin injection ,moreover they have the same safety .

Objective:To investigate the incidence of acute kidney injury (AKI) following cardiac surgery and related risk factors in 4 878 patients.Methods:The information from patients who underwent cardiac surgery through March 2015 to October 2015 was collected retrospectively from the electronic database of Beijing Anzhen Hospital. A total of 4 878 patients were divided into AKI group and non-AKI group according to whether AKI occurred within 7 days after cardiac surgery. The incidence of AKI was calculated, and the AKI incidence in different types of cardiac surgeries were compared. Clinical data such as baseline clinical information, operation information, comorbidity, hospital stay time, life ability score in discharge from the hospital, and so on, were compared between AKI group and the non-AKI group using univariate analysis. Risk factors for AKI following cardiac surgery were analyzed using the binary multivariate logistic regression.Results:A total of 933 patients suffered from AKI (19.1%) following cardiac surgery. The time of stay in the hospital was longer in AKI group than that in the non-AKI group [(14.4±8.9) vs (13.7±7.7) d, P<0.05)]. The incidence of AKI in different types of cardiac surgeries varied significantly ( P<0.001). The logistic regression analysis showed that male, diabetes, hypertension, the elevated basic serum creatinine, cardiac dysfunction (NYHA grade≥Ⅲ), cardiopulmonary bypass, a combination of operations≥3, the rethoracotomy exploration and hemostasia, and using an invasive ventilator for over 96 hours were the independent risk factors for the AKI following cardiac surgery (all P<0.05), and the odds ratio (95% confidence interval) were 1.81(1.46-2.24), 1.29(1.03-1.62), 5.85(4.73-7.22), 1.81(1.36-2.40), 4.49(3.60-5.60), 1.84(1.49-2.27), 23.24(18.25-29.59), 2.34(1.45-3.77) and 1.94(1.09-3.43) respectively. Conclusions:The incidence of AKI after cardiac surgery in Beijing Anzhen Hospital is 19.1%. AKI following cardiac surgery prolongs the time of stay in the hospital. Independent risk factors for AKI following cardiac surgery are multiple, and one of the most critical factors is a combination of operations≥3.
