Shenqi Jiangtang Granule Ameliorates Kidney Function by Inhibiting Apoptosis in a Diabetic Rat Model

Diabetic nephropathy (DN) is a major microvascular complication of diabetes. In addition to moderating hyperglycemia, Shenqi Jiangtang Granule (SJG) had a beneficial effect on kidney function in a clinical trial. However, the mechanism involved remains unclear. This study was conducted to identify the underlying molecular mechanisms. A diabetic rat model was generated by using a high-fat diet and streptozotocin (STZ) injection. Then, rats were given SJG at dosages of 400 mg/kg/d or 800 mg/kg/d by gavage for 8 weeks. After 8 weeks of treatment, blood glucose, serum creatinine, blood urea nitrogen (BUN), and 24-h urinary albumin were measured. Histochemical staining and TdT-mediated dUTP nick-end labeling (TUNEL) assays were performed in kidney. Kidney genomic expression in the SJG-treated group and diabetic group was detected by using a genome expression microarray. We found that SJG treatment reduced blood glucose, serum creatinine, BUN, and 24-h urinary albumin and affected kidney histology. The gene array revealed that the expression of 99 genes increased and the expression of 91 genes decreased in the HSJG group, compared with those of in the diabetic group. Pathway and gene ontology analysis of the differentially expressed genes showed an enrichment of the apoptosis pathway. SJG treatment reduced TUNEL- and caspase-3-positive cells in diabetic kidneys. SJG upregulated Bcl-2 and regucalcin expressions and reduced casp3 and Apaf1 expressions in diabetic rats. Our results suggest that SJG exerts a renal protective effect through the inhibition of cell apoptosis in a diabetic rodent model.

Background: Type 2 Diabetes Mellitus (T2DM) is a world-wide metabolic disease with no cure from drugs and treatment. In China, The Traditional Chinese Medicine (TCM) herbal formulations have been used to treat T2DM for centuries. Methods: In this study, we proposed a formula called ShenQi Compound (SQC), which has been used in clinical therapeutics in China for several years. We evaluated the effect of SQC in a spontaneous diabetic rat model (GK rats) by detecting a series of blood indicators and performing histological observations. Meanwhile, the gene microarray and RT-qPCR experiments were used to explore the molecular mechanism of SQC treatment. In addition, western medicine, sitagliptin was employed as a comparison. Results: The results indicated that SQC and sitagliptin could effectively improve the serum lipid (blood Total Cholesterol (TC) and blood Triglycerides (TG)), hormone levels (serum insulin (INS), Glucagon (GC) and Glucagon-Like Peptide-1 (GLP-1)), alleviated the inflammatory response (hypersensitive C-Reactive Protein (hsCRP)), blood glucose fluctuation (Mean Blood Glucose (MBG), standard deviation of blood glucose (SDBG) and Largest Amplitude of plasma Glucose Excursions (LAGE)), pancreatic tissue damage and vascular injury for T2DM. Compared with sitagliptin, SQC achieved a better effect on blood glucose fluctuation (p<0.01). Meanwhile, the gene microarray and RT-qPCR experiments indicated that SQC and sitagliptin may improve the T2DM through affecting the biological functions related to apoptosis and circadian rhythm. Moreover, SQC might be able to influence the mTOR signaling pathway by regulating Pik3r1, Ddit4 expression. Conclusion: All these results indicate that SQC is an effective therapeutic drug on T2DM. Notably, SQC presents an obvious blood glucose fluctuation-preventing ability, which might be derived from the regulation of the mTOR signaling pathway.

Objective: To investigate the effects of curcumin on blood lipid and blood glucose levels and its mechanism in diabetic rat model. Method: After streptozotocin (STZ) induced diabetic rat model, large, medium and small doses of curcumin group were partly given curcumin solution 400,200,100mg·kg-1, administered once a day, continuously 30 days. In 30 th day, determine blood glucose (BG) value, after the last injection , determine the serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) levels. Results: Compared with the model group rats, each dose of curcumin group rats’ BG, TC, TG and LDL-C levels were significantly decreased, HDL-C levels was increased significantly. Conclusion: Curcumin has a certain impact on blood lipids and blood glucose in diabetic rat model.

ABSTRAKDaun mahkota dewa (Phaleria macrocarpa) diketahui memiliki efek anti hiperglikemik dengan menghambat aktivitas enzim pencerna karbohidrat a-glucosidase, namun efeknya pada kondisi diabetes belum diketahui. Penelitian ini bertujuan untuk mengetahui efek antidiabetik ekstrak etanol daun mahkota dewa (EEDMD) terhadap berat badan dan kadar glukosa darah tikus model diabetes. Studi eksperimental dengan rancangan post test only control group design dilakukan terhadap subjek 45 ekor tikus Sprague Dawley. Subjek dikelompokkan dalam kontrol normal, kontrol diabetes diberi pelarut dan diabetes diberi 7mg/200g, 14mg/200g, and 28mg/200g EEDMD secara peroral, sekali sehari selama 3, 14 dan 25 hari. Model tikus diabetes dibuat dengan injeksi streptozotosin dan nicotinamide. Hasil analisa statistik berat badan dan kadar glukosa puasa antar kelompok terdapat perbedaan yang signifikan. Sehingga kesimpulan penelitian ini adalah pemberian EEDMD memiliki efek antidiabetik pada tikus diabetes yang dinduksi stretozotosin.Kata kunci: Diabetes Mellitus, Phaleria Macrocarpa, Ekstrak Etanol, Streptozotosin, Antidiabetik ABSTRACTPhaleria macrocarpa leaf has been known to have anti-hyperglycemic effects by inhibiting the activity of a-glucosidase carbohydrates digestive enzyme, but the systemic effect on diabetic condition is unknown yet. This study was conducted to investigate the antidiabetic effect of ethanolic extract of Phaleria macrocarpa leaf (EEPML) on body weight and blood glucose levels of diabetic rat model. This was a quasi experimental study with post test only control group design. Fourty five male Sprague Dawley rats were classified into normal control group, diabetic control group with solvent, diabetic with 7mg/200g, 14mg/200g, and 28mg/200g of EEPML peroral administration, once a day for 3, 14 and 25 days. The diabetic rat model was made by streptozotocin and nicotinamide injection. Results : Statistical analysis of mean body weight and fasting blood glucose level showed there were significant differences between treatment groups. Conclusion : Administration of EEPML is able to affect the body weight and blood glucose level of diabetic rat model.
