Objective To study the effects of glimepiride and short-term intensive therapy with insulin on plasma glucose and beta-cell function in newly diagnosed type 2 diabetic patients.Methods 80 newly diagnosed type 2 diabetic patients were divided into two groups of 40 patients each and randomly treated with insulin or glimepiride plus metformin for 8 weeks.The FBG,2hPBG,HbA_1c,improvement of beta-cell function were measured before and after intensive therapy in each group.Results After the treatment,FBG,2hPBG,HbA_1c were significantly decreased (all P<0.001) in each group;FCP and 2hPCP were increased(P<0.05)in each group.Conclusion Glimepiride or short-term intensive therapy with insulin plus metformin could effectively improve glycemic control and beta-cell function in newly diagnosed type 2 diabetic patients.

Objective To investigate the role and its mechanisms of tea polyphenols (TP) in the prevention of diabetic renal fibrosis.Methods Mouse model of diabetes mellitus was induced by high-fat diet combined with intraperitoneal injection of streptozotocin (STZ,50 mg/kg).Real-time quantitative polymerase chain reaction (RT-PCR) and Western blotting were used to determine the transcription and expression of genes related to the renal fibrosis.Results Diabetic mouse model was successfully established by injection of high-fat diet plus STZ.The transcription of E-cadherin was decreased and transcriptions of genes related to the renal fibrosis such as transforming growth factor β1 (TGF-β1),vimentin,α-smooth muscle actin (α-SMA),fibronectin,collagen Ⅰ,and collagen Ⅳ were increased in the renal tissues of diabetic mice,which indicated the diabetic nephropathy with renal fibrosis in diabetic mice.Treatment of diabetic mice with TP for 8 weeks could reverse the process of diabetic nephropathy with renal fibrosis in accompanied with the increase of E-cadherin transcription and decrease of TGF-β1-targeted genes such as vimentin,α-SMA,fibronectin,collagen Ⅰ,and collagen Ⅳ in the renal tissues of diabetic mice.Moreover,incubation of normal rat kidney proximal tubular epithelial cell line (NRK-52E) cells with TGF-β1 could also induce the changes in fibrotic morphological and transcription or expression of fibrosis related genes,and all effects of TGF-β1 could be inhibited by TP treatment in NRK-52E cells.Conclusions These results indicate that chronic treatment with TP may relieve renal fibrosis of diabetic nephropathy through the inhibition of TGF-β signaling pathway and provide important experimental data for the prevention and treatment of diabetic nephropathy.

OBJECTIVE To provide certain therapeutic ideas and references for the pharmaceutical care of severe Legionella pneumonia in anti-infection treatment. METHODS Clinical pharmacists participated in the entire treatment process of a patient with severe Legionella pneumonia， and assisted clinical physicians in evaluating the infecting pathogens using the WUH （Winthrop- University Hospital criteria） scoring system， based on the patient’s clinical symptoms， physical signs， and changes in pulmonary imaging. Leveraging their pharmaceutical expertise， clinical pharmacists recommended a combination of piperacillin sodium and tazobactam with moxifloxacin hydrochloride for anti-infection treatment， and closely monitored the patient’s clinical manifestations. They promptly identified delirium and abnormally elevated levels of lipase， amylase and liver enzymes， and successively suggested adjusting the treatment plan to a combination of piperacillin sodium and tazobactam with doxycycline or azithromycin for anti- infection after analyzing the causes， along with liver protection treatment， enteral nutrition， and parenteral nutrition. Additionally， clinical pharmacists closely monitor the patient’s medication adherence and provide her with medication education. RESULTS The clinical physicians accepted the recommendations of the clinical pharmacists， and the patient improved after treatment and was discharged. A follow-up examination one month later showed no recurrence. CONCLUSIONS Clinical pharmacists， when assisting clinicians in treating severe Legionella pneumonia， not only pay attention to changes in the patient’s clinical symptoms and physical signs， but also closely monitor the adverse reactions of fluoroquinolone， tetracycline， and macrolide antibiotics. They should promptly recognize adverse reactions and provide recommendations for adjusting treatment plans， as well as offer comprehensive pharmaceutical care throughout the patient’s treatment， to ensure the effectiveness and safety of clinical therapy.
