Objective To explore the therapeutic effect and nursing points of different linked modes in hemodialysis combined with hemoperfusion on renal osteopathy disease in maintenance hemodialysis (MHD) patients.Methods Sixty-four MHD patients with renal osteopathy disease were enrolled in the study.They were divided into two groups by random digits table method:the front connection group and the back connection group with 32 cases each.Their clinical data,serum parameters and complications were recorded.The therapeutic effect of two groups were compared.Results The serum level of intact parathyroid hormone(iPTH) was (191.36 ± 53.96) ng/L in the front connection group,while (133.02 ± 38.63) ng/L in the back connection group,and there was significant difference,t=3.517,P＜0.05.The incidence of lower blood pressure and blood coagulation were 8.85％(51/576),6.94％(40/576) in the back connection group,while 14.93％(86/576),15.97％(92/576) in the front connection group,and there were significant differences,x2=10.149,23.136,P＜0.01.Conclusion The back linked mode in hemodialysis combined with hemoperfusion can obviously decrease iP:TH of MHD patients combined with renal osteopathy disease and has less complications,worth clinical promotion.

The clinical data and routine biochemical parameters of 64 maintenance hemodialysis (MHD)patients and 20 controls were analyzed in the study.Serum cystatin C levels were detected by latex particle enhalice inununo-turbidimetry:and the cardial structure and function were assessed by echocardiography.As MHD time extended,the levels of semm cystatin C increased gradually,accompanied with high incidence of left ventricular hypertrophy(LVH).The LVH-positive patients had higher systolic blood pressure and left veHtricular mass index,and had higher serum cystatin C than tllose in LVH-negative patients.The serum cystatin C levels were positively correlated with left yentricular mass index(r=0.633,P<0.01)and systolic blood pressure(r:0.397,P<0.01).The results suggest that serum cystatin levels may be an influencing factor for long-term cardiacvascular complication in MHD patients.

AIMTo explore the effects of sinomenine(Sin) on intracellular free calcium ([Ca2+]i) and the activity of PKC (protein kinase C) of the cultured aortic vascular smooth muscle cells (VSMC) during ischemia and hypoxia.

METHODSThe effect of Sin on changes in [Ca2+]i were determined in cultured rabbit VSMC after exposure to high K+, norepinephrine (NE) and caffeine (Caf). Fluorescent Ca2+ -indicater fura-2/AM was used. The effects of Sin were compared with that of verapamil (Ver). The hypoxia model was made, then the activity of PKC was measured by y scintillation counting instrument.

RESULTSSin (10 x 10(-6) mol x L(-1), 3 x 10(-5) mol x L(-1) 10(-4) mol x L(-1)) inhibited the elevation of [Ca2+]i induced by high K+ -depolarization in a concentration dependent manner. In addition, Sin inhibited the elevation of [Ca2+]i induced by NE in the presence of extracellular Ca2+. In the absence of extracellular Ca2+, Sin (3 x 10(-5) mol.L(-1)) also had no blocking effect on the NE-induced [Ca2+]i increase. It was found that the activity of PKC treated with Sin in VSMC cytoplasm and cell membrane in normal condition increased, the activity of PKC in cytoplasm in ischemia and hypoxia situation increased, but the activity of PKC in cell membrane decreased. When VSMC was treated with Sin, the activity of PKC in cytoplasm decreased and that of cell membrane increased.

CONCLUSIONThe results suggest that Sin might decrease the[Ca2+] i of VSMC by blocking both VDC and ROC, could regulate the PKC activities induced by ischemia and hypoxia.

Objective This study was to explore the prevalence of overweight and obesity,and the effects of contextual and individual level determinants on them in the rural areas of Kunming city.China.Methods Shilin County was selected as the study site.Probability Proportional to Size(PPS)sampling method was used to select representative sample of 6006 residents aged 45 years and over from Shilin.Information was obtained from a cross-sectional survey on health.Data was analyzed using a muhilevel logistic modeling.Results The prevalence rates of overweight and obesity were 12.10% and 2.15% in the study area.Males had a higher prevalence of overweight than females(13.60% vs.10.71%).Similar situation was seen in the prevalence of obesity(2.82% vs.1.52%).Both village level and individual level variables were associated with obesity.whereas only individual level variables were related to overweight.Elderly had lower probability of being overweight and obese than younger people with odds ratio(OR)as 0.95(95% CI:0.83-0.97)and 0.93(95% CI:0.82-0.96),respectively.Males had higher probability of being overweight and obese than females:OR of 0.89(95% CI:0.78-0.98)and OR of 0.87(95% CI:0.78-0.97),respectively.Individuals with lower family income had increased probability of having obesity (OR=0.81,95% CI:0.73-0.95).Factor as living in a higher income village was associated with lower prevalence of obesity(OR=0.92,95% CI:0.85-0.98).Conclusion Interventions at village level on obesity in parallel with those at individual level were needed.Prevention and intervention on obesity should be emphasized in villages with higher income.

A new mathematical equation characterizing the compression of pharmaceutical materials is presented. This equation presumed that the rate of change of the compressible volume of powder with respect to the pressure is proportional to the compressible volume. The new model provided a good fit to several model substances employing non-linear regression techniques. The validity of the model had been verified with experimental results of various pharmaceutical powders according to the Akaikes informatics criterion (AIC) and the sum of squared deviations (SS). The parameter of the new model might reflect quantitatively the fundamental compression behaviors of the powders. It had demonstrated that the proposed model could well predict the compaction characteristics of solid particles like the Kawakita model.

Fluidized-bed manufactured enteric-coated diclofenac sodium pellets were compressed into tablets. The blend of two aqueous acrylic resins dispersion in different ratios, Eudragit NE30D and Eudragit L30D-55, were used to prepare enteric-coated diclofenac sodium pellets of different particle sizes and coating level. The cushioning pellets with different properties and these enteric-coated pellets were compressed into tablets in different proportions. The drug release of the tablets containing these pellets would be lower than 10% in 2 h in simulated gastric fluid, but reach (83 +/- 2.42)% in 1 h in simulated enteric fluid. The mixture of Eudragit NE30D and Eudragit L30D-55 could be used to prepare enteric pellets which are suitable for compression. The cushioning pellets which were composed of stearic acid/microcrystalline cellulose (4:1, w/w) could avoid rupture of the coating of pellets during the compression.

Microcrystalline cellulose (MCC), calcium phosphate (DCP)/MCC (4:1, w/w) and lactose (Lac)/MCC (4:1) pellets with different intragranular porosity were prepared in an extrusion-spheronizator and three volume ratios of ethanol/water were used as binder agents to prepare pellets. The compression behaviors of these pellets with different intragranular pore volume were evaluated with the parameters of Kawakita model. The results showed that high pore volume of pellets made up of MCC had the best compressibility and low pore volume of pellets had a poor compactibility. However, the compressibility of different porosity of pellets made up of DCP/MCC (4:1) or Lac/MCC (4:1) was good, but they were not significantly different. The reason might be the main compression mechanism of high porosity of MCC pellets was plastic deformation and that of DCP/MCC pellets or Lac/MCC pellets was not plastic deformation but fragmentation. These results can be observed directly by the SEM photographs. According to these results, the conclusion could be drawn that high porosity MCC pellets and different porosity DCP/MCC pellets and Lac/MCC pellets can be used as cushion granules to maintain the original shape and release characteristics of drug pellets when pellets were tabletted.

OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.
