Objective Cardiovascular mortality and morbidity is common in dialysis patients and fluid overload is the most important contributor. The aim of this study was to investigate the relationship between volume overload and hypertension in elderly continuous ambulatory peritoneal dialysis (CAPD) patients and effect of dietary salt restriction on blood pressure control. Methods Thirty-eight CAPD patients with age of 60 years old and over were enrolled in the present study. 38 patients with CAPD were restricted the intake of salt and fluid in stable CAPD patients for two months. Their body weight, extracellular water (ECW), intracellular water (ICW), total body water (TBW), blood pressure, serum albumin levels, urine volume and ultrafiltrate volume were measured before and after the dietary restriction. Bioimpedance analysis was used to assess their fluid status. ECW was normalized by patients' ideal weight (nECW). Results After dietary salt restriction, significant deceases in body weight 〔(60.5?10.3) kg vs (58.5?9.7) kg, P =0.000〕, ECW 〔(15.81?3.03) L vs (14.65?2.61) L, P =0.000〕 and systolic blood pressure 〔(134.0?18.3) mm Hg vs (128.3?21.0) mm Hg, P =0.05〕 were observed in 26 patients whereas the opposite changes were observed in the remaining 12 patients. A significant correlation was found between systolic blood pressure and nECW both before and after two months of dietary restriction ( r _ pre =0.379, P =0.019; r _ post =0.393, P =0.016) and between the changes in systolic blood pressure and changes in nECW ( r =0.514, P =0.001). Conclusions The present study suggests that there is a positive correlation between fluid status and blood pressure. Most of the elderly CAPD patients are fluid overloaded and that dietary salt restriction may be an effective way to control volume and blood pressure. However, the compliance of patients to dietary salt restriction can influence the effect.

Objective To compare respiratory syncytial virus(RSV)infection and inflammatory responses between immunocompetent BALB/c mice and immanodeficient nude mice.Methods At various time points after BSV infection of BALB/c mice and nude mice,pulmonary viral titers were assayed.Leukocvtes in bronchoalveolar lavage fluid(BALF)and pulmonary histology were identified.F4/80+cells and CD49b+cells in lung tissue were examined by immunohistochemistry,and the cytokines of TNF-α,IL-12,IFN-r and IL-10 in BALF were assayed by ELISA.Results RSV titers in infected BALB/c mice and nude mice peaked on the 3rd day postinoculation,and nude mice had higher-level and more durative viral replication than BALB/c mice.RSV infection induced more severe pulmonary histopathology and larger number of leukocytes in airway in nude mice than in BALB/c mice.RSV infection enhanced more pulmonary F4/80+macrophages,CD49b+ NK cells in both mice.Furthermore infected nude mice had larger amount of pulmonary macrophages and NK cells than infected BALB/c mice.RSV infected BALB/c mice secreted more TNF-α,IL-12,IFN-r and IL-10 as compared with control BALB/c mice,and infected nude mice had hisher level of TNF-α.IL-12 and IL-10 than infected BALB/c mice.Conclusion Nude mice are good model for severe and pemistent RSV infection in immunocomprised hosts.The inflammation induced by RSV infection is not parallel with the immune response of T cells,and macrophages and NK cells are potent immunocytes and inflammatory cells in RSV infection especially when T lymphocytes are absent.

Objective To investigate the antiviral effects of antisense phosphorothioate oligodeoxynucleotide (ASODN)in 9HTEO infected with influenza A virus (IFAV) in vitro. Methods The ASODN which complemented to genomic PB1, M2, NS, PB2, HA mRNA of IFAV was used to investigate antiviral effection in vitro. The cytopathic effect (CPE) was observed, and the cell survival rates were measured by MTF assay, plaque assay, RT-PCR, Western blot and Immunofluorescence were performed to test anti-viral efficiency of PB1, M2, NS in cells mRNA and protein level. Results 9HTEO cells infected with IFAV almost all died when the multipicity of infection (MOI) is aboved after 5 days cell culture. The ASODN could increase the cell survival rates. The IFAV PB1, M2, NS significantly reduced CPE of IFAV infected 9HTEO cells, reduced the viral replication of IFAV in the cells (P <0.05). Conclusion The ASODN which targeted the mRNA of IFAV gene showed a significant and specific anti-IFAV effect both in mRNA and protein level in cells culture system. The study indicates that the PB1, M2 and NS mRNA may play an important role in regulating IFAV replication, and ASODN may have inhibitory activity on IFAV replication. The results established the basis for further study on new drugs against IFAV infection include the highly pathogenic H5N1 influenza virus.

Objective To investigate the relationship of fascin-1 protein expression with the metastasis of basal cell carcinoma and squamous cell carcinoma. Methods Skin specimens were obtained from 10 normal human controls, 13 patients with basal cell carcinoma (8 nodular variant and 5 superficial variant) and 24 patients with SCC (11 SCC in situ and 13 invasive SCC). Immunohistochemical staining was performed to analyze the expression of fascin-1 protein. The staining results were quantitatively assessed with computer image analysis system (Image-pro Plus 6.0). Results The optical density of fascin-1 averaged 0.1152±0.04574 in SCC in situ, 0.1257±0.03096 in invasive SCC, and 0.0293±0.00981 in normal controls; the expression of fascin-1 was significantly higher in SCC tissue than in normal control skin (both P<0.05). Increased optical density was also observed for fascin-1 in nodular variant of SCC (0.0808 ±0.05642) and superficial variant of SCC (0.0806±0.04346) compared with the normal controls, whereas no statistical difference was observed between nodular and superficial variant of SCC. Conclusion In BCC and SCC, there is an over expression of fascin-1, which may be linked to the local invasion of carcinoma,

Objective To explore the safety and feasibility of coronary angiography (CAG) via percutaneous left radial artery approach (LRA) compared with right radial artery approach (RRA) in aged patients, and determine whether LRA is a valid alternative for CAG. Methods A total of 502 consecutive patients who were aged 65 or older underwent diagnostic CAG were recruited and randomized to the LRA group (240 patients) or RRA group (262 patients). The study end points included total procedural duration, coronary time, fluoroscopy time, dose of radiation including cumulative air kerma and dose area product, contrast volume, and the incidence of vascular complications. Results Coronary procedural success rate was 96.2%(231/240) in LRA group and 96.2%(252/262) in RRA group. There was no significant difference (P>0.05). The radial cannulation time, fluoroscopy time, look through time, dose of radiation, contrast volume and the percentage of hydrophilic wire used in two group had no significant difference (P > 0.05). The catheter in place time in LRA was significantly shorter than that in RRA group:(2.7 ± 2.5) min vs. (3.3 ± 3.3) min, P=0.036). There was a trend toward shorter procedural duration in LRA group than that in RRA group, but there was no significant difference: (13.3 ± 6.1) min vs. (14.3 ± 6.2) min, P=0.075. Conclusions LRA approach has similar safety and feasibility in terms of performing coronary angiography compared with RRA.It seems to be a feasible alternative for CAG in aged patients.
