Objective The application value of left ventricular global longitudinal strain(LVGLS)in early cardiac function impairment in diabetes mellitus was analyzed by two-dimensional speckle tracking imaging.Methods A total of 45 patients with diabetes mellitus who were treated in Loudi Central Hospital from January 2023 to January 2024 were selected as study objects.Based on the levels of glycosylated hemoglobin(HbA1c),patients were divided into group A(HbA1c≤11.5％,20 cases)and group B(HbA1c＞11.5％,25 cases).The clinical data and echocardiographic parameters of two groups were compared.The relationship between clinical data,echocardiographic parameters and LVGLS was analyzed by multifactor linear regression.Results Weight and LVGLS in group B were significantly lower than those in group A,HbA1c and interventricular septal thickness were significantly higher than those in group A(P＜0.05).Multifactor linear regression analysis showed that there was a linear relationship between HbA1c and LVGLS(β＝-0.511).Conclusion Increased HbA1c in diabetes mellitus patients is an independent risk factor for LVGLS.

Objective: To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m², 10 mg/m² or 12 mg/m² as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) . Methods: A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m²) as induction chemotherapy in newly diagnosed patients of adult AML. Results: Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (P<0.001) . After adjusted for age, blast ratio of bone marrow, FAB classification and risk stratification, the odds ratios (95% CI) of IDA 10 mg/m² group and IDA 12 mg/m² group were 0.49 (0.34-0.70) and 0.36 (0.18-0.71) , as compared with the IDA 8 mg/m² group (P<0.001, P=0.003) . In the intermediate and favorable groups, CR rates was 76.5% (163/213) , 86.9% (506/582) and 86.1% (68/79) in different doses of IDA (P=0.007) . Interestingly, IA regimen with IDA 10 mg/m² was the only beneficial factor affecting CR in this group after adjusted for age, blast ratio of bone marrow and FAB classification[OR=0.47 (95% CI 0.31-0.71) , P<0.001]. CR rates in adverse group was 50.0% (18/36) , 60.6% (43/71) and 81.8% (18/22) respectively (P=0.089) . However, the odds ratios (95% CI) of IDA 12 mg/m² when compared with the IDA 8 mg/m² was 0.22 (0.06-0.80) , after adjusted for age, blast ratio of bone marrow and FAB classification. The median time (days) of neutrophil count less than 0.5×10⁹/L in IDA 8 mg/m² group, IDA 10 mg/m² group and IDA 12 mg/m² group were 14 (11-18) , 15 (11-20) and 18 (14-22) , respectively (P=0.012) and of platelet count lower than 20×10⁹/L were 14 (7-17) , 15 (11-20) and 17 (15-21) , respectively (P=0.001) . The incidences of lung infection in the three groups were 9.8%, 13.5% and 25.2%, respectively (P<0.001) . Conclusions For young adult patients (aged 18-60 years) with AML in China, intensifying induction therapy with idarubicin 10 mg/m² is clinically superior to IDA 8 mg/m² and IDA 12 mg/m² in favorable intermediate AML subgroup. However, idarubicin 12 mg/m² is more suitable to adverse AML subgroup.

Objective To investigate the clinical features and effective treatment of patients with severe type A H1N1 flu in Wenzhou. Methods The clinical data of 42 hospitalized patients with severe type A H1N1 flu were analyzed and the clinical features were summarized. Results A total of 42 patients with severe type A H1N1 flu all began with fever and cough. The symptoms of expectoration, pharyngalgia, chilly accounted for 92. 9%, 90. 5% and 42. 9%, respectively. The peripheral leucocyte counts were normal or reduced. C-reactive protein and erythrocyte sedimentation rate levels both increased in 30 patients (71.4%). About 95.2% (40/42) patients had changes of pulmonary imaging. All of the patients were treated with oseltamivir and effective antibiotic drugs as well as symptomatic management. No patients was treated with glucocorticoid. The patients with underlying diseases were given proper treatment. Three cases were treated with antifungal therapy and 3 pregnant patients were timely terminated of pregnancy. Conclusions Severe type A H1N1 flu progresses rapidly and the lower respiratory tract is involved soon after onset. Therefore, the patient should be diagnosed early and treated promptly after presenting fever, which will lead to good prognosis.
