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.

Population pharmacokinetics of vancomycin (VAN) in the Chinese patients was described by using nonlinear mixed-effects modeling (NONMEM). 619 VAN serum concentrations data from 260 patients including 177 males and 83 females were collected separately from two centers. A one-compartment model was used to describe this sparse data. No significant difference was observed between two center datasets by introducing SID covariate. The final model was as CL= (θ (base0+ θ(max) x(1 -e(-θ(Age)(Age/72) and V = θ x θ (Age)(Age/72). The creatinine clearance (CL(Cr)) and Age were identified as the most significant covariate in the final model. Typical values of clearance (CL) and volume of distribution (V) in the final model were 2.91 L x h(-1) and 54.76 L, respectively. Internal model validation by Bootstrap and NPDE were performed to evaluate the robustness and prediction of the final model. The median and 95% confidence intervals for the final model parameters were based on 1000 Bootstraps. External model evaluation was conducted using an independent dataset that consisted of 34 patients to predict model performance. Pharmacodynamic assessment for VAN by AUC (0-24 h) to MIC ratios of over 400 was considered to be the best to predict treatment outcomes for patients. AUC (0-24 h) was calculated by clearance based on the above population model. The results indicate that the conventional dosing regimen probably being suboptimal concentrations in aged patients. The approach via population pharmacokinetic of VAN combined with the relationship of MIC, Age, CL(Cr) and AUC(0-24 h)/MIC can predict the rational dose for attaining efficacy.

To establish a molecular identification method for Bletillae Rhizoma, this paper extracted genome DNA from Bletillae Rhizoma and its adulterants. The sequences of rDNA ITS2 were sequenced after amplifying. Then multiple alignments of ITS2 were constructed phylogenetic tree with Neighbor Joining by MEGA 5. 1 and found out SNPs loci. The result showed that rDNA ITS2 region could identify Bletillae Rhizoma and its adulterants. There existed the SNPs loci, which could identify Bletilla striata and B. ochracea. Furthermore, we designed specific primers against the SNPs loci of B. striata and B. ochracea, then screened primers and optimized the PCR amplification conditions. Finally, the DNA of B. striata and B. ochracea were specifically amplified by BJ59-412F, BJ59-412R and HHBJ-225R. The length of amplification products were respectively about 350 bp and 520 bp that were effectively identified of B. striata and B. ochracea. While, the adulterants of Bletillae Rhizoma were no-reaction occurring. To sum up, the amplification conditions of the primers can identify B. striata, B. ochracea and their adulterants successfully at the same time. This method was easy, time-saving, and reliable, which can be used as a rapid method for molecular identification of Bletillae Rhizoma.

BACKGROUND: Immune function of chemotaxis signal has been a key focus in medical research. However, the immune activation and related action mechanism of chemotatic factor RANTES are unclear.OBJECTIVE: To investigate the immune activation and related action mechanism of chemotatic factor RANTES stimulation on peripheral mononuclear cells.DESIGN: Control Experiment.SETTING: Department of Urologic Surgery, Clinical Medical College, Yangzhou University.MATERIALS: The experiment was performed at the Laboratory of Department of Immunology, University of Louisville from December 2004 to August 2005. Main reagent and equipments included RPMI 1640 complete medium, recombinant human RANTES, anti-CD3 monoclonal antibody, pyrrolidine dithiocarbamate(PDTC),CTLA4Ig, LS500 liquid scintillation counter and FACS Epics XL flow cytometry.METHODS: Peripheral mononuclear cells were collected and stimulated by different concentrations of recombinant human RANTES and/or anti-CD3 monoclonal antibody. Cells with significantly proliferative response were intervened by pyrrolidine dithiocarbamate (PDTC) or CTLA4lg. 3H-thymidine incorporation was used to detect the proliferation of mononuclear cells. Flow cytometry was applied to measure the phenotypes of lymphocytes.MAIN OUTCOME MEASURES: Incorporation efficiency of 3H-thymidine, the ratio of CD4 to CD8, expression of CD25,CCR5 and CD28.RESULTS: Proliferative reaction of mononuclear cells reached two peaks with recombinant human RANTES concentrations of 100 μg/L and 5000 μg/L respectively. The proliferation of peripheral mononuclear cells stimulated by 100 μg/L recombinant human RNATES was significantly higher than that in the presence of 50 μg/L anti-CD3 monoclonal antibody (P<0.05).There were no rivalry or synergistic effect between them.The immune active effects of recombinant human RANTES could be inhibited by PDTC or CTLA,Ig in a dose dependent manner.After RANTES treatment,the level of cell surface CD25 increased (P<0.05) and the CCR5 expression decreased (P<0.05), but there were no significant differences in CD28 expression and the ratio of CD4/CD8 of lymphocytes(P>0.05).CONCLUSION: RANTES has a specific function of inducing the immune activation of mononuclear cells. This special signal works depending on the activation of interleukin-2 signal pathway, CD28 co-stimulatory pathway and nuclear factor-κB,but independent of CD3 activation.

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.
