Objective To observe the effects of Tongluo recipe on extracellular signal-regulated protein kinase (ERK1/2) pathway in the kidneys of streptozotocin-induced rat models of type 1 diabetes mellitus, andto explore the renoprotective mechanism of Tongluo recipe. Methods Adult male Sprague-Dawley rats were randomly divided into 2 groups: control group (A, n = 10) and experimental group. Rats in the experimental group were induced by intraperitoneal injection of streptozotocin (60 mg/kg body mass), and were randomly subdivided into group B (diabetic control, n = 10), group C (diabetic rats treated with low dose of Tongluo recipe, 0. 5 g/[kg • d], n = 10), group D (diabetic rats treated with medium dose of Tongluo recipe, 1. 0 g/[kg • d], n = 10), group E (diabetic rats treated with high dose of Tongluo recipe,2. 0 g/[kg • d], n = 10) and group F (diabetic rats treated with losartan, 30 mg/[kg • d],n=10). At the end of the 12th week rats were sacrificed, and the serum glucose, triacylglycerol(TG), total cholesterol(Choi), serum creatinine(Scr), urea nitrogen(BUN) in blood, 24-hour urine protein(Upro24), microalbuminuria (MAU), and creatinine in urine(UCR) were examined. The kidney mass/body mass (KM/BM) and creatinine clearance rate (Ccr) were calculated. The left kidneyswere collected, weighed and subjected to H-E staining and PAS staining to observe the pathological changes; serum and renal tissue angiotensin II (Ang II) levels were determined by ELISA; the expression of phosphorylated ERK1/2(p-ERK1/2) was detectedby immunohistochemical staining and vascular endothelial growth factor (VEGF) protein expression was determined by Western blotting analysis. Results Compared with group B, group D had a slighter mesangial proliferation under light microscope. Besides, rats in group D had significantly decreased Ccr, BUN, MAU, and Upro24 in the serum, and decreased Ang II in the serum and renal tissue, and decreased KM/BM, VEGF and p-ERK1/2 levels in renal tissue compared with rats in group B(P<0. 05). The medium dose of Tongluo recipe and losartan showed similar effects in improving the renal function and inhibiting Ang II, VEGF, and p-ERK1/2 expression of diabetic rats. Conclusion The renoprotective effect of Tongluo recipe may be related to inhibition of ERK1/2 cascade pathway by decreasing the expression of Ang II and VEGF.

Objective To observe the effects of Tongluo reeipe on extracellular signal-regulated protein kinase (ERK1/2) pathway in the kidneys of streptozotocin-induced rat models of type 1 diabetes mellitus, and to explore the renoprotective mechanism of Tongluo reeipe. Methods Adult male Sprague-Dawley rats were randomly divided into 2 groups: control group (A, n=10) and experimental group. Rats in the experimental group were induced by intraperitoneal injection of streptozotocin (60 mg/kg body mass), and were randomly subdivided into group B (diabetic control, n=10), group C (diabetic rats treated with low dose of Tongluo recipe,0.5g/[kg · d], n=10), group D (diabetic rats treated with medium dose of Tongluo recipe, 1.0g/[kg · d], n=10), group E (diabetic rats treated with high dose of Tongluo recipe, 2.0g/[kg · d], n=10) and group F (diabetic rats treated with losartan, 30 mg/[kg · d],n=10). At the end of the 12th week rats were sacrificed, and the serum glucose, triacylglycerol(TG), total cholesterol(Chol), serum creatinine(Scr), urea nitrogen(BUN) in blood, 24-hour urine protein(Upro24), microalbuminuria (MAU), and creatinine in urine (UCR) were examined. The kidney mass/body mass (KM/BM) and creatinine clearance rate (Ccr) were calculated. The left kídneys were collected, weighed and subjected to H-E staining and PAS staining to observe the pathological changes; serum and renal tissue angiotensin II (Ang II) levels were determined by ELISA; the expressíon of phosphorylated ERK1/2 (p-ERK1/2) was detected by immunohistochemical staining and vascular endothelial growth factor (VEGF) protein expression was determined by Western blotting analysis. Results Compared with group B, group D had a slighter mesangial proliferation under light microscope.

Objective: To observe the effects of Tongluo recipe on the renal expression of connective tissue growth factor (CTGF), advanced glycation end products receptor (RAGE) and phosphorylated extracellular signal regulated kinase (p-ERK1/2) in streptozotocin-induced rat model of type 1 diabetes mellitus, and to explore the mechanism of its renoprotective effect. Methods: Adult male Sprague-Dawley rats, weighing 180-220 g, were randomly divided into 2 groups: control group (A, n=10) and model group (n=50). Rat diabetic model was induced by intraperitoneal injection of streptozotocin (60 mg/kg body weight), and the model rats were randomly subdivided into B group (diabetic control, n=10), C group (diabetic rats treated with low dose of Tongluo recipe, 0.5 g·kg-1·d-1, n=10), D group (diabetic rats treated with medium dose of Tongluo recipe, 1.0 g·kg -1·d-1, n=10), E group (diabetic rats treated with high dose of Tongluo recipe, 2.0 g·kg-1·d-1, n=10), and F group (diabetic rats treated with losartan, 30 g·kg -1·d-1, n=10). At the end of the 12th week the rats were sacrificed and were weighed; the urea nitrogen (BUN) in blood, serum creatinine (Scr), 24 h albumin excretion rate (UPRO24), microalbuminuria (MAU) and creatinine in urine (Ucr) were analyzed by bio-chemical methods. The left kidneys were weighed and the right kidneys were subjected to real-time PCR analysis for the expression of CTGF and RAGE mRNA. Western blotting analysis was used to examine the expression of CTGF, RAGE, p-ERK1/2, and total-ERK1/2 protein expression. Results: The creatinine clearance rate, urea nitrogen, 24 h albumin excretion rate, and microalbuminuria in group D and E were significantly lower than those of group B. And the renal functions of rats in group D and E were improved and the expression of RAGE and CTGF mRNA and protein and p-ERK1/2 protein expression was significantly decreased (P<0.05). Conclusion: Tongluo recipe may exert its renoprotective effect through inhibiting RAGE-ERK1/2-CTGF signal pathway.

Radiomics utilizes the high-throughput extraction of large amounts of quantitative features from radiographic images,giving a comprehensive quantification of tumor phenotype.Thus it can provide complementary and interchangeable information for clinical usage,such as differentiating malignant nodules from benign ones,predicting response to treatment,identifying lymph node metastasis,improving individualized treatment selection and monitoring.The advantages of radiomics give it great potential in precise treatment.But much work needs to be done before it could be used in practice.It is imperative that a standard research procedure is needed to verify its reliability and clinical value via multi-central prospective clinical trials.
