Objective To investigate the effect of intra-dialytic exercises on micro-inflammatory state in maintenance hemodialysis (MHD) patients. Methods Sixty clinically stable MHD patients from the Hemodialysis Center were enrolled in the study . The patients were divided into exercise group and control group with 27 cases in each group by using the random digit number table. The patients in the exercise group underwent a 6-month intra-dialytic exercise, in which the patients conducted physical exercises supinely on a cycle ergometer each for 50 minutes, 3 times a week. The patients in the control group were treated without any exercise intervention. Serum interleukin-6(IL-6), C-reactive protein(CRP) and tumor necrosis factor-α(TNF-α) were determined after the study for 0 and 6 months. Results After the 6-month intradialytic exercise program, serum IL-6, CRP and TNF-α were all decreased in the exercise group (P < 0.05). These indices were unchanged in the control group (P > 0.05). Conclusion The intra-dialytic exercises can alleviate micro-inflamatory state in maintenance hemodialysis patients.

The expression of brain aquaporin 4 (AQP4) is different at the different stages of cellular differentiation, and distribution of brain AQP4 is affected by the existence of endothelial cells. Other factors including osmolality, ammonia, hypoxia, temperature, hormone, C-type natriuretic peptide, lead, complement inhibitor, lipopolysaccharide can also influence AQP4 expression in astrocytes. However, the regulating mechanisms for brain AQP4 expression are not clear. Protein interaction, protein kinase C (PKC) through protein phosphorylation, mitogen-activated protein kinase signal pathway, Ca2+ signaling cascade signal pathway and transcription factor pathway have been proposed, among which phosphorylation of PKC for the inhibition of AQP4 is frequently studied.

Objective To observe the efficacy of treating allergic rhinitis majorly by needling three nasal acupoints, and to provide a safe convenient and effective method for the treatment of allergic rhinitis.Method Sixty-two patients were randomly divided into an acupuncture group (31 cases) and a Western medication group (31 cases), and the acupuncture group was mainly treated by three nasal acupoints, and the Western medication group was by Clarityne. By comparing the symptoms and signs, the clinical efficacies were evaluated.Result The total effective rate was 87.1% in the acupuncture group, significantly higher than 76.7% in the Western medication group (P<0.01).Conclusion It’s effective to treat allergic rhinitis by adopting acupuncture at the three nasal acupoints as the major method.

Objective To investigate the protective effect of gynostemma on myocardium and its mechanism in patients with diabetes associated with hyperlipemia.Methods 178 patients with type 2 diabetes mellitus with hyperlipidemia from the department of endocrinology in our hospital were selected and divided into two groups, 89 cases in the control group treated with basic treatment of diabetes+atorvastatin, 89 cases in the experiment group received gynostemma on the basis of the control group, myocardial injury index, blood glucose level, blood lipid level, serum cytokine levels and serum oxidative stress response indexes were detected and compared after the treatment.Results Compared with the control group, serum levels of aspartate aminotransferase(AST), creatine kinase(CK), CK-MB, lactate dehydrogenase(LDH)were lower in the experiment group after treatment, fasting plasma glucose(FPG), 2h postprandial blood glucose(2hPG), HbA1c level were lower after treatment, serum levels of total cholesterol(TC), triglycerides( TG ) , low-density lipoprotein cholesterol ( LDL-C ) were lower, high-density lipoprotein cholesterol ( HDL-C ) level was higher after treatment, serum level of adiponectin(ADPN) was higher, tumor necrosis factor-alpha(TNF-α), interleukin-6(IL-6), interleukin-18(IL-18) levels were lower after treatment, serum levels of malondialdehyde(MDA), reactive oxygen species(ROS) were lower, glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) levels were higher after treatment, with significant difference (P<0.05).Conclusion Gynostemma can significantly reduce the cardiac muscle damage of patients with diabetes associated with hyperlipemia , plays a role in myocardial protection, the mechanism may be to reduce blood glucose and blood lipid levels, inhibit the inflammatory reaction caused by inflammatory cytokines, improve the antioxidant capacity of the body and reduce oxidative stress damage.

Good palatability of pediatric drugs improves the accuracy of dosing and adherence to dosing regimens. Many active pharmaceutical ingredients have an undesirable taste, so effective taste masking methods need to be developed to improve the palatability of pediatric medicines. This article mainly introduces the commonly taste masking techniques and taste evaluation methods, and puts forward suggestions on the concerns and general principles of the pharmaceutical evaluation of taste masking effects based on cases, in order to provide reference for the development of drug taste masking technology in children.

Objective: To investigate the influence of high-fat diet on glucose metabolism and fatty acid composition of serum phospholipid in OLETF rats, a model of spontaneous type 2 diabetes mellitus. Method: Twenty male OLETF rats of 14 w age were divided into 2 groups randomly. The dietary fat in two groups contained identical percentages of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. Oral glucose tolerance test and measurement of insulin level were performed after 10 w treatment. The fatty acid composition of serum phospholipid in rats was observed as well. Results:The food intakes were comparable in 2 groups. The body weight gain in high-fat group was higher than standard group during the experiment. The result of oral glucose tolerance test and measurement of insulin level showed that the glucose metabolism in two groups had no significant difference. Only the percentage of total n-6 polyunsaturated fatty acids, 18:3(n-3) of serum phospholipid were comparable, percentages of other fatty acids were significantly different in two groups. Conclusion:With the comparable fatty acid composition, higher dietary fat lead to more body weight gain, but had no significant influence on glucose metabolism in OLETF rats. The amount of dietary fat had significant effect on fatty acids composition of serum phospholipid in OLETF rats.

ObjectiveTo observe the expressions of Caspase-9,Caspase-3, cytochrome C and their relationships, and investigate apoptotic mechanisms in hippocampus of post-traumatic stress disorder(PTSD) rats. Methods Sixty male Wistar rats were used in the present study. The single-prolonged stress (SPS)-method was used to set up the rat PTSD models. There were six groups:after SPS 1 day,4 days,7 days,14 days,28 days groups and control group. The expressions of caspase-9, Caspase-3 and Cytochrome C proteins were detected with immunohistochemistry, immunofluorescence and Western blotting. Results Immunohistochemical and immunofluorescent results showed that the expression of cytochrome C peaked at 4 days and maintained higher level at 7days after SPS. Expressions of Caspase-9 and Caspase-3 were increased and peaked at 7days after SPS. Western blotting results showed that compared with control group, cytochrome C protein was up-regulated and peaked at 4 days after SPS in the cytosol. Compared with the control group, cytochrome C tended to decrease in mitochondrial fractions. The activated form of Caspase-9 and caspase-3 were not detected in control group. They were present in model groups. Cleaved- caspase-9 and cleaved-caspase-3 peaked at 7 days after SPS, and then gradually decreased at 14 days. Conclusion The neuronal apoptosis in hippocampus of PTSD rats may be one of the causes inducing hippocampus atrophy. Mitochondrial apoptotic pathway is involved in apoptosis in the hippocampus of PTSD rats.
