This study was aimed to compare the effect of insulin plus rosiglitazone with that of insulin plus metformin on the level of serum N-terminal pro-brain natriuretic peptide (NT-BNP) in patients with type 2 diabetes mellitus, and to find out whether serum NT-BNP can be used as an index for predicting heart failure induced by rosiglitazone in the cases of type 2 diabetes mellitus. Sixty type 2 diabetic patients were recruited and were randomly divided into two groups: group A (n = 30) received insulin plus rosiglitazone (4 mg/d) and group B (n = 30) received insulin plus metformin. The observations covered an 8-weeks' course of treatment. Serum NT-BNP was measured at the beginning and at the end of 8 weeks. The Before-After study revealed that the level of serum NT-BNP did not change apparently in the two groups (P >0.05). There was no remarkable difference in the level of serum NT-BNP between the two groups (P>0.05). There were 3 cases with edema in the group of insulin plus rosiglitazone, but none with heart failure; in these three cases, the mean serum NT-BNP level at the end of the treatment exhibited an increase of 108.99 fmol/ml when compared with that at the beginning. Neither insulin plus rosiglitazone nor insulin plus metformin had apparent effect on the level of serum NT-BNP in the patients with type 2 diabetes mellitus. The question of whether serum NT-BNP is a predictive index of heart failure awaits answers given by more observation on type 2 diabetes mellitus patients using rosiglitazone.

Objective:To explore the clinical characteristics of autosomal dominant polycystic kidney disease (ADPKD).Methods:Clinical data of 103 patients with ADPKD first admitted to Renmin Hospital of Wuhan University from July 2017 to April 2021 were retrospectively analyzed. The clinical characteristics of patients in different renal function stages were analyzed, and multiple linear regression analysis was used to analyze the factors reflecting the severity of the disease.Results:Among the 103 patients with ADPKD, there were 49 males (47.6%), aged (51.23±10.99) years old. The extrarenal manifestation was mainly polycystic liver (64/71). The main clinical symptoms were gross hematuria (25 cases, 24.3%), lumbar distend and pain (37 cases, 35.9%) and hypertension (69 cases, 67.0%), appearing in the whole course of the disease. Early treatment was mainly drug conservative treatments (58 cases, 56.3%), followed by renal cyst aspiration (34 cases, 33.0%), and surgical treatments (11 cases, 10.7%). Patients in chronic kidney disease (CKD) stage 5 were mainly treated with conservative treatments (28/34). Laboratory examination results showed that hemoglobin, platelet, lymphocyte percentage and albumin in CKD stage 4-5 were lower than those in CKD stage 1-3 (all P<0.05) ; prothrombin time (PT), PT-international standardized ratio and plasma osmotic concentration in CKD stage 4-5 were higher than those in CKD stage 1-3 (all P<0.05). Multiple linear regression analysis showed that hemoglobin ( β=0.249, P=0.005), platelet ( β=0.207, P=0.005), lymphocyte percentage ( β=0.305, P<0.001) and plasma osmotic concentration ( β=-0.362, P<0.001) were correlated with estimated glomerular filtration rate. Conclusions:The clinical manifestations of ADPKD patients are hypertension, lumbar distend and pain, and gross hematuria, which can run through the whole stage of CKD. Polycystic liver is more common in extrarenal system. Hemoglobin, platelets, lymphocyte percentage and concentration osmotic concentration may be related to the disease progression of ADPKD.

Objective To investigate the density seasonal fluctuation and insecticide resistance of Anopheles sinensis in the Taibai Lake area and to provide a scientific basis for formulation of Anopheles sinensis control strategy.Methods The surveillance was carried out from June to October in 2013-2016.The adult mosquito density was monitored using human bait trapping method.WHO bioassay method was used to measure the sensibility of mosquitoes to insecticides.Results In 2013-2016,totally 2 318 Anopheles sinensis were captured,the Anopheles sinensis peaked in late July till early August,which were 67-127,317-386,77-89,107-139,respectively.Anopheles sinensis showed high resistance to dichlorodiphenyltrichloroethane,malathion,and initial resistance to propoxur and deltamethrin (mortality ratio:38.10％,41.82％,86.11％,83.02％).Conclusions The Taibai Lake area has a diverse Anopheles sinensis population,its seasonal fluctuations and insecticide resistance monitoring can provide effective guidance for malaria control.In order to prevent the development of resistance to the insecticides,integrated management measures should be adopted in the future.
