This study is to develop a therapeutic drug monitoring (TDM) network server of tacrolimus for Chinese renal transplant patients, which can facilitate doctor to manage patients' information and provide three levels of predictions. Database management system MySQL was employed to build and manage the database of patients and doctors' information, and hypertext mark-up language (HTML) and Java server pages (JSP) technology were employed to construct network server for database management. Based on the population pharmacokinetic model of tacrolimus for Chinese renal transplant patients, above program languages were used to construct the population prediction and subpopulation prediction modules. Based on Bayesian principle and maximization of the posterior probability function, an objective function was established, and minimized by an optimization algorithm to estimate patient's individual pharmacokinetic parameters. It is proved that the network server has the basic functions for database management and three levels of prediction to aid doctor to optimize the regimen of tacrolimus for Chinese renal transplant patients.

To evaluate the effect of components in Guanxin Ⅱ prescription on the pharmacokinetic profiles of paeoniflorin and ferulic acid. METHODS: Drug concentrations of rat plasmas after intravenous injection of paronia pall (PPE) or ferulic acid (FA) extract solution, as well as oral administration of PPE and FA solution, and different kinds of decoctions based on Guanxin Ⅱ prescription were determined by an HPLC system. NONMEM (nonlinear mixed-effect modeling) method was used to analyze the population pharmacokinetics of PF and FA. RESULTS: A two-compartment model with first order degradation in absorption phase, and an ordinary two-compartment model were adequately describe PF and FA pharmacokinetic profiles, respectively. The mean of PF population parameters, CL1, V1, CL2, V2, Ka0, and Ka1, were 0.509 L/h, 0.104 L, 0.113 L/h, 0.123 L, 0.135 /h, and 0.0135 /h, respectively, while the typical values of CL1, V1, CL2, V2, Ka1, and F in FA model were 0.295 L/h, 0.025 L, 0.0331 L/h, 0.0518 L, 0.110 /h, and 0.40, respectively. Inter-individual variabilities were estimated and dose formulation (DF) was identified as a significant covariate in the model. CONCLUSION: The results indicate that the pharmacokinetic behaviors of index components in Guanxin Ⅱ prescription can be influenced by different dose formulations administrated in rats.

Objective To analyze the abnormal detectable rates of different kinds of blood test indexes before and after treatment in the patients with snake bite and to probe into the change condition of these indexes after different snake bite .Methods The inpa‐tients with clearly diagnosed what kind of snake bite in the past two years were selected as the research subjects .The multiple blood test indexes were determined before and after treatment in these patients .The abnormal detectable rates of these indexes were ana‐lyzed and compared among various snake bite patients .Results The different kinds of snake bite all could cause the different de‐grees of changes in some detection indexes among partial patients .Specially ,the detectable rates of WBC ,PT ,APTT ,TT ,D‐D ,CK , CK‐MB ,LDH ,Urea ,Cr and Cys‐C increase and PLT and Fbg decrease caused by viper bite were apparently higher than those caused by other kinds of snake bites (P<0 .05) .The detectable rates of CO2 increase and K+ decrease in the coral snake bite were apparently higher than those in trimeresurus gramineus ,cobra and viper bite (P<0 .05) .Conclusion Because the snake species and toxicities are different in the various snake bites ,so the caused changes and the abnormal detectable rates of blood test indexes also are different .

Objective:To evaluate the changes of quality of life in patients with axial spondyloarthritis (ax-SpA) after treatment with non-steroidal anti-inflammatory drugs (NSAIDs) by the 36-item Short Form Health Survey (SF-36).Methods: 120 patients diagnosed with ax-SpA were collected in the first Affiliated Hospital of Zhengzhou University from October 2014 to September 2015.They all agreed to be treated with the special drugs and assessed by special scale.Then they all signed the agreement.In the 3 months,double-blind,parallel controlled trial patients were randomized to 200 mg twice daily (bid) imrecoxib,or 200 mg twice daily (bid) celecoxib.They were assessed for the changes of quality of life at enrollment and after three months of NSAIDs therapy by the SF-36 of Chinese edition.The correlation between quality of life and erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),Bath Ankylosing Spondylitis Disease Activity Index (BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI),Spondylo Arthritis Research Consortium of Canada (SPARCC) was analyzed.Results: A total of 116 ax-SpA patients completed the study and 4 patients were lost to follow-up.We used the SF-36 scale to assess the quality of life in patients with ax-SpA before and after 3 months,NSAIDs treatment.The treatment effects were not statistically significant difference between the two drugs (P>0.05).After all the patients were treated with NSAIDs for 3 months,there was statistically significant difference (P<0.05) of the physical functioning,role-physical,bodily pain,general health,social functioning,role-emotional;and there was no statistically significant difference (P>0.05) of vitality and mental health.The positively significant correlations had been identified between BASDAI and PF,RP,BP,GH,VT,SF,RE (P<0.05),while no significant correlation was found between BASDAI and MH (P>0.05).A positively significant correlation had been identified between BASFI and PF,RP,BP,GH,SF,RE,MH (P<0.05),while no significant correlation was found between BASFI and VT (P>0.05).The ESR was positively correlated with SF,RE (P<0.05);and CRP was positively correlated with SF,MH (P<0.05);and SPARCC was positively correlated with PF (P<0.05).BASDAI and BASFI were the important influence factors of PF (P<0.05);and BASDAI was the important influence factor of BP,GH,VT,RE(P<0.05);BASFI was the important influence factor of RP,SF,MH(P<0.05).Conclusion: Non-steroidal anti-inflammatory drugs can improve the quality of life of the ax-SpA patients.Imrecoxib and celecoxib have the equivalent curative effect.SF36 scale is suitable for the assessment of the quality of life in patients with ax-SpA.

Objective To investigate the mechanism on JAK/STAT1 signal pathway in SAHA down-regulation of indoleamine 2,3-dioxygenase (IDO) in gallbladder carcinoma cells.MethodsWe treated gallbladder carcinoma SGC-996 cells with IFN-γ and SAHA.Western blotting was used to detect the expression of IDO,signal transducer and activator of transcription 1 (STAT1) phosphorylation and interferon regulatory factor genes-1 (IRF-1).Confocal microscopy analysis was used to detect STAT1 translocation.Transient transfections and reporter genes assay was used in detecting the activation of γ-activated sites (GAS) and interferon stimulated response elements (ISRE).ResultsIDO expressed in SGC-996 cells in dose- and time-dependent manners when stimulated with IFN-γ.SAHA down-regulated the expression of IDO induced by IFN-γ in a dose-dependent manner.SAHA blocked the expression of IRF-1 induced by IFN-γ.SAHA inhibited the IFN-γ-induced STAT1 phosphorylation and nuclear translocation.SAHA down-regulated IFN-γ-induced activation of GAS and ISRE.ConclusionsSAHA may down-regulate IDO expression through inhibiting the activation of members in JAK/STAT1 signal pathway.This may provide a new immunotherapeutic strategy to break tumor immune tolerance in gallbladder carcinoma.

Objecfive To investigate the clinical characteristics,treatment and prognosis of autoimmune diseases associated and non-autoimmune diseases associated hemophagocytic syndrome.Methotis Clinical records of 15 cases witll secondary hemophagocytic syndrome'were collected and the relations with treatment and prognosis was analyze.The similarities and differences between autoimmune disease associated bemophagocytic syndrome (group A)and non-autoimmune disease associated hemophagocytic syndrome (group B)were compared.Fisher exact test,t test and Willcoxen test were used for statistical analysis.Results Both groups had fever,bleeding,jaundice,hepatosplenomegaly,and arthralgia,skin rash and positive of autoantibodies in group A were discovered specifically.But in group B,the patients with icterus were mo common(38% vs 100%,p=0.018).There was no significant difference in their laboratory data and prognosis when compared between the two groups(P>0.05).The patients who received corticosteroids and IVIG and/or immunosuppressive agents had better prognosis(P<0.05).Conclusion Except for icterus there is no significant difference in clinical features and laboratory data among autoimmune disease associated hemophagocytic syndrome and other secondary hemophagocytic syndrome.And the therapy with corticosteroids combined with IVIG and/or immunosupprcssive agents is effective.

In this study, we evaluated the influence of different variance from each of the parameters on the output of tacrolimus population pharmacokinetic (PopPK) model in Chinese healthy volunteers, using Fourier amplitude sensitivity test (FAST). Besides, we estimated the index of sensitivity within whole course of blood sampling, designed different sampling times, and evaluated the quality of parameters' and the efficiency of prediction. It was observed that besides CL1/F, the index of sensitivity for all of the other four parameters (V1/F, V2/F, CL2/F and k(a)) in tacrolimus PopPK model showed relatively high level and changed fast with the time passing. With the increase of the variance of k(a), its indices of sensitivity increased obviously, associated with significant decrease in sensitivity index for the other parameters, and obvious change in peak time as well. According to the simulation of NONMEM and the comparison among different fitting results, we found that the sampling time points designed according to FAST surpassed the other time points. It suggests that FAST can access the sensitivities of model parameters effectively, and assist the design of clinical sampling times and the construction of PopPK model.
