OBJECTIVE:To observe the effects of alprostadil combined with papaverine on blood coagulation indexes and complications in uremic hemodialysis patients after initial arteriovenous fistula.METHODS:One hundred and eighteen uremic hemodialysis patients undergoing initial arteriovenous fistula in our hospital during Feb.-Jun.2015 were divided into control group and observation group according to random number table,with 59 cases in each group.Both groups received local irradiation with hemodialysis internal fistula repair instrument 30 min,tid,from 3 days before surgery to 10 days after surgery.Control group was treated with Alprostadil injection 10 μg,iv,qd,immediately after surgery.Observation group was additionally treated with Papaverine in jection 30 mg,iv,qd,on the basis of control group.Both groups received treatment for 10 d.The orificium fistulae blood flow,hemodialysis blood flow and the time of initial hemodialysis were compared between 2 group.The plasma prothrombin time (PT),activated partial thromboplastin time (APTT),fibrinogen (Fib),platelet count (PLT) and C-reactive protein (CRP) levels were observed in 2 groups before and after surgery.The occarrence of postoperative complications was observed.RESULTS:The orificium fistulae blood flow and hemodialysis blood flow of observation group were significantly higher than those of control group,and ini tial hemodialysis time was significantly shorter than control group,with statistical significance (P＜0.05).Before surgery,there was no statistical significance in PT,APTT,Fib,PLT and CRP between 2 groups (P＞0.05).After surgery,APTT and CRP of 2 groups were increased significantly,Fib was decreased significantly;the above indexes of observation group was significantly better than that of control group,with statistical significance (P＜0.05).There was no statistical significance in PT,PLT between 2 groups (P＞0.05).There was no statistical significance in the incidence of internal fistula infection and postoperative wound bleeding volume＞ 10 mL between 2 groups (P＞0.05).The incidence of internal fistula occlusion and orificium fistulae thrombus in observation group were significantly lower than control group,with statistical significance (P＜0.05).CONCLUSIONS:The application of alprostadil combined papaverine on uremic hemodialysis patients after initial arteriovenous fistula can effectively prevent inflammation reaction,fistula thrombus formation and fistula occlusion,and improve the maturation of fistula.

Objective:Investigating the expression of HIV-1 co-receptors CXCR4,CCR5 and chemoking SDF-1 in human placentae and trophoblasts is to explore the mechanism of in-utero transmission of human immunodeficiency virus type 1(HIV-1).Methods:Using semi-quantitative reverse transcriptase-polymerase chain reaction,detected the transcripts of CXCR4,CCR5 in placenta tissues and trophoblasts.Immunocytochemistry and immunohistochemistry analysis revealed the expression of CXCR4,CCR5 in primary cultured first trimester trophoblasts and villous tissue.Also the expression of SDF-1 in villi of first trimester,and the presence of SDF-1 in the culture of isolated trophoblasts were examined by in situ hybridization,immunohistochemistry and enzyme-linked immunosorbent assay.Results:CXCR4 and CCR5 mRNA were detected in placentae of various gestational phases and in first trimester trophoblasts.However,primary cultured trophoblasts were found to be reactive only with antibodies against CXCR4.In the villous tissue sections,CXCR4 was found in trophoblasts,while CCR5 in stromal cell and/or Hofbauer cell.First trimester trophoblasts expressed SDF-1 strongly and secreted SDF-1 in vitro.Conclusion:CXCR4 and CCR5 were expressed in placentae.Hence,they maybe involved in in-utero transmission of HIV-1 as co-receptors.However,SDF-1 expressed in trophoblasts may protect fetus from being invaded by X4-HIV-1.R5-HIV-1 may infect CCR5+ stromal cells and/or Hofbauer cells through placental disruptions.

BACKGROUND:Establishing the animal model of membranous nephropathy is of importance to figure out the pathogenesis of membranous nephropathy.
OBJECTIVE:To investigate the expression of nephrin and podocin in the model of membrane nephropathy in rats, and to investigate their relationships with the pathogenesis of membranous nephropathy.
METHODS:A total of 40 Sprague-Dawley rats were equivalently randomized into model and control groups. Rats in the model group were in premunity by given subcutaneous and multi-point injection of 1 mg cationic bovine serum albumin firstly dissolved in 0.5 mL normal saline and then ful y emulsified with the equal incomplete Freund’s adjuvant for 1 week, and 16 mg/kg cationic bovine serum albumin was injected via vein tails, once every other day for 4 weeks. The same volume of normal saline was injected into the controls. The mRNA expressions of nephrin and podocin in renal tissues were detected using real-time PCR, and biochemical indicators and morphological observation were measured at 2 and 4 weeks after modeling.
RESULTS AND CONCLUSION:(1) In the model group, the total amount of urine and serum albumin levels were significantly decreased accompanying with overt proteinuria, and the serum creatinine, urea nitrogen, cholesterol and triglyceride levels were significantly increased al in a time-independent manner compared with the control group (P<0.01), and the difference was significant (P<0.05). (2) The pathological examination showed that rats in the model group had different degrees of renal tubular dilatation, glomerular basement membrane thickening, mesangial cel s and stromal hyperplasia, which was typical of membranous nephritis. (3) Moreover, the mRNA expressions of podocin and nephrin in the model group were lower than those in the control group. (4) In conclusion, the decreased expressions of podocin and nephfin may disturb the integrity of the slit membrane of podocytes giving rise to the damage of glomerular filtration barrier, and proteinuria appears in final.

OBJECTIVE:To investigate the possibility of constructing anti-cancer drug in-situ hydrogel with self-assembling peptide RAD16-Ⅰ. METHODS:The rheological parameters as storage modulus(G′),loss modulus(G″)and phase angle(Δ)of 0.1%,0.2% and 0.5% RAD16-Ⅰ solution containing paclitaxel or not were determined by rheometer before and after mixing with isometric phosphate buffer solution (PBS);RAD16-Ⅰ solution containing paclitaxel or not were mixed with breast cancer MDA-MB-435S cells culture medium to obtain hydrogel,the status and effect of which on cell morphology were observed by in-verted microscope (compared with paclitaxel solution). RESULTS:In RAD16-Ⅰ solution containing paclitaxel or not,G′was close to or slightly higher than G″,and G′and G″had changed slightly as the concentration of peptide increased. Compared with not mixed with PBS,G′increased significantly in concentration-dependent manner after mixed with PBS,and G″also increased but was slighter than G′;Δ decreased significantly. In cell culture media,RAD16-Ⅰ solutions containing paclitaxel could form hy-drogel and maintain their gel form,cancer cells kept same morphology after treated with hydrogel and same concentration of pacli-taxel solution for same time. CONCLUSIONS:RAD16-Ⅰ solutions containing paclitaxel can form hydrogel under simulated physi-ological conditions,which can maintain their gel form and have anti-cancer effect of paclitaxel.

Objective To investigate the pharmacokinetics ( PK ) and pharmacodynamics ( PD ) processes of rabeprazole in inhibiting gastric acid secretion with the combined PK-PD model. Methods A total of 10 healthy volunteers were given a intravenous infusion of 20 mg rabeprazole over a 30-min period. The concentration of rabeprazole in the plasma at different time points was detected by HPLC,and the PK parameters were calculated by DAS 2. 0 software. At the same time the intragastric pH was monitored over 24 hours to fit the PD parameters with indirect inhibition model. Results The main PK parameters,t1/2,Cmax,and AUC were(60. 5±17. 3)min,(1 299. 1±201. 0)ng·mL-1,and(106. 4±26. 0)mg·min·L-1, respectively.The corresponding PD parameters,Kin,Ke,IC50 and Imax were(8.200±3.362)h-1,(1.080±0.378)h-1,(0.286± 0. 129)mg·L-1 and(6. 93± 2. 15)pH,respectively. Conclusion The PK of rabeprazole in healthy volunteers conforms to one compartment model,and the PD fits the indirect response inhibition model. The equation can effectively establish the relationship between the blood drug concentration and the effect.
