Impacts of exposure to 900 MHz mobile phone radiation on liver function in rats

Objective: To study the impacts of exposure to electromagnetic radiation(EMR) on liver function in rats. Methods: Twenty adult male Sprague-Dawley rats were randomly divided into normal group and radiated group. The rats in normal group were not radiated, those in radiated group were exposed to EMR 4 h/d for 18 consecutive days. Rats were sacrificed immediately after the end of the experiment. The serum levels of alanine aminotransferase(ALT) and aspartate aminotransferase(AST), and those of malondialdehyde(MDA) and glutathione(GSH) in liver tissue were evaluated by colorimetric method. The liver histopathological changes were observed by hematoxylin and eosin staining and the protein expression of bax and bcl-2 in liver tissue were detected by immunohistochemical method. Terminal-deoxynucleotidyl transferase mediated nick and labelling(TUNEL) method was used for analysis of apoptosis in liver. Results: Compared with the normal rats, the serum levels of ALT and AST in the radiated group had no obvious changes(P>0.05), while the contents of MDA increased(P<0.01) and those of GSH decreased(P<0.01) in liver tissues. The histopathology examination showed diffuse hepatocyte swelling and vacuolation, small pieces and focal necrosis. The immunohistochemical results displayed that the expression of the bax protein was higher and that of bcl-2 protein was lower in radiated group. The hepatocyte apoptosis rates in radiated group was higher than that in normal group(all P<0.01). Conclusion: The exposure to 900 MHz mobile phone 4 h/d for 18 days could induce the liver histological changes, which may be partly due to the apoptosis and oxidative stress induced in liver tissue by electromagnetic radiation.

Effect of Liraglutide Combined with Nephritis Rehabilitation Tablets for Type 2 Diabetic Nephropathy

Objective: To explore the effect of liraglutide combined with Nephritis Rehabilitation Tablets in the treatment of type 2 diabetic nephropathy. Methods: Ninety patients with type 2 diabetic nephropathy who had received treatment in the Hospital from January 2018 to March 2019 were enrolled, and then randomly divided into a Liraglutide group, a Nephritis Rehabilitation Tablets group and a combined treatment group, with 30 cases in each group. All patients were given routine treatment. Besides, the Liraglutide group was treated with subcutaneous injection of liraglutide, the Nephritis Rehabilitation Tablets group was treated with oral Nephritis Rehabilitation Tablets, and the combined treatment group was given subcutaneous injection of liraglutide and oral administration of Nephritis Rehabilitation Tablets. The three groups were treated continuously for 12 weeks to compare the changes of glucose metabolism index, renal function and inflammatory factors. Results: After treatment, the levels of FPG, 2hPG and HbALc were decreased in the three groups, and the levels in the combined treatment group were lower than the liraglutide group and the Nephritis Rehabilitation Tablets group, and the liraglutide group lower than the Nephritis Rehabilitation Tablets group. The difference was statistically significant (P<0.05). After treatment, the levels of serum creatinine and urea nitrogen decreased in the three groups, and the levels in the combined treatment group were lower than the liraglutide group and the Nephritis Rehabilitation Tablets group, and the Nephritis Rehabilitation Tablets group lower than the liraglutide group. The difference was statistically significant (P<0.05) After treatment, the levels of IL-6, TNF-α, and hs-CRP decreased in the three groups, and the levels in the combined treatment group were lower than the liraglutide group and the Nephritis Rehabilitation Tablets group. The difference was statistically significant (P<0.05). Conclusions: For patients with type 2 diabetic nephropathy, Liraglutide combined with Nephritis Rehabilitation Tablets can help reduce the blood sugar, relieve renal inflammation and improve their renal function.

Effects of Irbesartan and Metformin on tumor necrosis factor receptor and monocyte chemotactic protein 1 in patients with early diabetic nephropathy

Objective: To explore the effect of Irbesartan and Metformin on tumor necrosis factor receptor 1 and monocyte chemoattractant protein-1 in patients with early diabetic nephropathy. Methods: A total of 162 patients with early diabetic nephropathy who had been admitted to the Hospital between February 2017 and February 2018 were randomly assigned into a Metformin group, an Irbesartan group, and a combination therapy group. The Metformin group were treated with oral Metformin, those in the Irbesartan group were given oral Irbesartan for treatment, and the combination therapy group was treated with Metformin combined with Irbesartan. After 3 months of continuous treatment, the levels of sTNFR1, high-sensitivity C-reactive protein, monocyte chemoattractant protein-1, glucose metabolism index, proteinuria, and serum creatinine levels in the two groups were compared. Results:After treatment, the levels of sTNFR1, sICAM-1, hs-CRP, and MCP-1 in the three groups decreased compared with those before treatment, and the levels in the combination therapy group were all shown to be lower than those of the Metformin group and the Irbesartan group, with statistically significant differences (P<0.05). The levels of glycosylated hemoglobin and fasting blood glucose in the three groups were significantly lower than before treatment, and those in the combination therapy group were lower than the Metformin group and Irbesartan group, where the difference was statistically significant (P<0.05). The 24-hour urinary protein quantification, urinary albumin excretion rate, and serum creatinine in the combination therapy group were lower than those in the Metformin group and in the Irbesartan group, where the differences were statistically significant (P<0.05). Conclusion: The effects of metformin combined with irbesartan on early diabetic nephropathy patients were significant, which can effectively reduce the levels of serum sTNFR1 and MCP-1, relieve inflammation and improve glucose metabolism and proteinuria level.

Effect of Llinagliptin on tumor necrosis factor receptor and monocyte chemoattractant protein-1 in patients with diabetic nephropathy

Objective:To explore the effect of Linagliptin on tumor necrosis factor receptor and monocyte chemoattractant protein-1 in patients with diabetic nephropathy.Methods: A total of 98 patients with diabetic nephropathy admitted to the Hospital from January 2017 to September 2018 were enrolled. The patients were divided into two groups according to the random double-blind method, with 49 cases in each group.

After 3 months of treatment, the levels of HbA1c, FPG, TC and TG in the experimental group were shown to be lower than the control group, and the difference was statistically significant. After 3 months of treatment, the levels of MCP-1, sTNFR1 and hs-CRP in the experimental group were lower than those in the control group, and the difference was statistically significant. There was no significant difference in incidence of adverse reactions between the two groups.Conclusion: For patients with diabetic nephropathy, Linagliptin is with higher safety, which can help improve their glycolipids metabolic levels and renal function, reduce the inflammatory response and the levels of MCP-1 and sTNFR1, and yet incur fewer adverse reactions.

Objective: To observe the effects of hemoperfusion combined with sequential dialysis on soluble tumor necrosis factor receptor in patients with diabetic kidney disease. Methods:A total of 100 patients with diabetic kidney disease who had been seeking treatment in the hospital between May 2015 and July 2017 were selected, and then according to the random number table method, these patients were divided into a control group and an observation group, with 50 cases in each group. The control group was treated with hemodialysis only, whereas the observation group was given hemoperfusion combined with sequential dialysis for treatment.
