Chinese Journal of cardiovascular Rehabilitation Medicine 2016;25(2):185-188
Objective:To observe therapeutic effect and influence of rosuvastatin on levels of interleukin (IL)-35 and nu- clear factor-κB (NF-κB)in patients with coronary heart disease (CHD).Methods:A total of 85 CHD patients were randomly divided into rosuvastatin group (n=43,received rosuvastatin calcium therapy based on routine treatment)and atorvastatin group (n=42,received atorvastatin calcium therapy based on routine treatment),both groups were treated for eight weeks all.Cardiac index (CI),cardiac output (CO),left ventricular ejection fraction (LVEF),left ventricular end-diastolic dimension (LVEDd),serum levels of IL-35 and NF-κB,and total effective rate were measured and compared be- tween two groups before and after treatment.Results:Compared with before treatment,there were significant rise in CI, CO,LVEF and IL-35 level,and significant reductions in LVEDd and NF-κB level in both groups after treatment (P<0.05 or<0.01).Compared with atorvastatin group after treatment,there were significant rise in CI [(3.54±0.72)L· min-1 ·m-2 vs.(3.88±0.83)L·min-1 ·m-2 ],CO [(3.78±0.89)L/min vs.(4.94±0.96)L/min],LVEF [(56.20 ±9.71)% vs.(63.48±14.15)%]and serum IL-35 level [(96.26±24.33)pg/ml vs.(106.92±27.26)pg/ml],and sig- nificant reductions in LVEDd [(4.71±0.89)cm vs.(4.36±0.75)cm]and NF-κB level [(21.51±5.01)ng/ml vs. (18.32± 5.17)ng/ml]in rosuvastatin group,P<0.05 all.Total effective rate of rosuvastatin group (95.35% vs. 76.19%)was significantly higher than that of atorvastatin group,P<0.05. Conclusion:Rosuvastatin possesses more sig- nificant therapeutic effect than that of atorvastatin on coronary heart disease,and its heart protection effect besides lipid lowering may be related to regulating levels of interleukin-35 and nuclear factor-κB.

Objective · To investigate the clinical characteristics of initial peritoneal dialysis (PD) patients with different peritoneal transport status, and analyze risk factors of high peritoneal transport status in PD patients. Methods · A total of 455 consecutive PD patients newly starting PD between January 2007 to October 2015 were retrospectively analyzed. According to the results of the first sPET, patients were divided into H/HA (4h D/Pcr ≥ 0.65) and L/ LA (4h D/Pcr<0.65) groups. Clinical and biochemical characteristics between the two groups were compared. Multivariate logistic regression model was established to investigate risk factors of higher peritoneal transport status of incident PD patients. Results · The study included 372 incident PD patients. The L/LA group and H/HA group had 264 cases (71.2%) and 108 cases (28.8%) respectively. The H/HA group had higher proportion of male patients (63.0% vs 50.8%, P=0.03), lower residual renal function [RRF, (4.26±2.77) mL/min vs (5.79±4.53) mL/min, P<0.01], lower serum albumin level [(29.34±6.89) g/L vs (32.08±5.86) g/L, P=0.00], and more frequent diabetic nephropathy (19.4% vs 9.5%, P=0.00), compared with L/LA group. Univariate and multivariate logistic regression analysis showed that higher peritoneal transport status was associated with lower serum albumin level (OR=0.96, 95% CI 0.28-0.99; P=0.02), male (OR=1.92, 95% CI 1.19-3.12; P=0.00), presence of diabetic nephropathy (OR=2.52, 95% CI 1.26-5.05; P=0.00) and lower residual renal function (OR=0.90,95% CI 0.83-0.96; P=0.00). The level of hsCRP in patients with hypoalbuminemia was higher than that in patients with normal albumin level (1.69 mg/L vs 0.69 mg/L, P=0.00). Conclusion · Low and low average peritoneal transport status accounted for the majority of the patients in this study. Low serum albumin levels, male, diabetic nephropathy, RRF were risk factors of initial high peritoneal solute transport status. Chronic inflammatory status might partially explain for the correlation between hypoalbuminemia and high peritoneal solute transport status in PD patients.

BACKGROUND/AIMS: Gastric hypersensitivity contributes to abdominal pain in patients with functional dyspepsia. Recent studies showed that hormones induced by stress are correlated with visceral hypersensitivity. However, the precise mechanisms underlying gastric hypersensitivity remain largely unknown. The aim of the present study was designed to investigate the roles of corticosterone (CORT) on excitability of dorsal root ganglion (DRG) neurons innervating the stomach. METHODS: DRG neurons innervating the stomach were labeled by DiI injection into the stomach wall. Patch clamp recordings were employed to examine neural excitability and voltage-gated sodium channel currents. Electromyograph technique was used to determine the responses of neck muscles to gastric distension. RESULTS: Incubation of acutely isolated DRG neurons with CORT significantly depolarized action potential threshold and enhanced the number of action potentials induced by current stimulation of the neuron. Under voltage-clamp mode, incubation of CORT enhanced voltage-gated sodium current density of the recorded neurons. Pre-incubation of GF109203X, an inhibitor of protein kinase C, blocked the CORT-induced hyperexcitability and potentiation of sodium currents. However, pre-incubation of H-89, an inhibitor of protein kinase A, did not alter the sodium current density. More importantly, intraperitoneal injection of CORT produced gastric hypersensitivity of healthy rats, which was blocked by pre-administration of GF109203X but not H-89. CONCLUSIONS: Our data strongly suggest that CORT rapidly enhanced neuronal excitability and sodium channel functions, which is most likely mediated by protein kinase C but not protein kinase A signaling pathway in DRG neurons innervating the stomach, thus underlying the gastric hypersensitivity induced by CORT injection.

PURPOSE: Allergic rhinitis (AR) is an inflammatory disorder of the upper airway. Exosomes or extracellular vesicles are nanosized vesicles of endosomal origin released from inflammatory and epithelial cells that have been implicated in allergic diseases. In this study, we characterized the microRNA (miRNA) content of exosomes in AR. METHODS: Extracellular vesicles were isolated from nasal mucus from healthy control subjects (n=10) and patients with severe AR (n=10). Vesicle RNA was analyzed by using a TaqMan microRNA assays Human Panel-Early Access kit (Applied Biosystems, Foster City, CA, USA) containing probes for 366 human miRNAs, and selected findings were validated with quantitative RT-PCR. Target prediction and pathway analysis for the differentially expressed miRNAs were performed using DIANA-mirPath. RESULTS: Twenty-one vesicle miRNAs were up-regulated and 14 miRNAs were under-regulated significantly (P<0.05) in nasal mucus from AR patients when compared to healthy controls. Bioinformatic analysis by DIANA-mirPath demonstrated that 32 KEGG biological processes were significantly enriched (P<0.05, FDR corrected) among differentially expressed vesicle miRNA signatures. Among them, the B-cell receptor signaling pathway (P=3.709E-09), the natural killer cell-mediated cytotoxicity (P=8.466E-05), the T-cell receptor signaling pathway (P=0.00075), the RIG-I-like receptor signaling pathway (P=0.00127), the Wnt signaling pathway (P=0.00130), endocytosis (P=0.00440), and salivary secretion (P=0.04660) were the most prominent pathways enriched in quantiles with differential vesicle miRNA patterns. Furthermore, miR-30-5p, miR-199b-3p, miR-874, miR-28-3p, miR-203, and miR-875-5p, involved in B-cell receptor and salivary secretion signaling pathways, were selected for validation using independent samples from 44 AR patients and 20 healthy controls. MiR-30-5p and miR-199b-3p were significantly increased in extracellular vesicles from nasal mucus when compared to healthy controls, while miR-874 and miR-28-3p were significantly down-regulated. In addition, miRNA-203 was significantly increased in AR patients, while miRNA-875-5p was found to be significantly decreased in AR patients. CONCLUSIONS: This study demonstrated that vesicle miRNA may be a regulator for the development of AR.
