ABSTRACT

OBJECTIVE@#To establish a clinically applicable model of rapid identification of adverse drug reaction program (RiADP) for risk management and decision-making of clinical drug use.@*METHODS@#Based on the theory of disproportion analysis, frequency method and Bayes method, a clinically applicable RiADP model in R language background was established, and the parameters of the model were interpreted by MedDRA coding. Based on the actual monitoring data of FDA, the model was validated by the assessing hepatotoxicity of lopinavir/ritonavir (LPV/r).@*RESULTS@#The established RiADP model included four parameters: standard value of adverse drug reaction signal information, empirical Bayesian geometric mean value, ratio of reporting ratio and number of adverse drug reaction cases. Through the application of R language parameter package "phViD", the model parameters could be output quickly. After being encoded by MedDRA, it was converted into clinical terms to form a clinical interpretation report of adverse drug reactions. In addition, the evaluation results of LPV/r hepatotoxicity by the model were matched with the results reported in latest literature, which also proved the reliability of the model results.@*CONCLUSIONS@#In this study, a rapid identification method of adverse reactions based on post marketing drug monitoring data was established in R language environment, which is capable of sending rapid warning of adverse reactions of target drugs in public health emergencies, and providing intuitive evidence for risk management and decision-making of clinical drugs.

ABSTRACT

In many industrialized countries, clinical pharmacy has developed into a separate discipline and become a vital part of inpatient care in hospitals. However, as compared to many established branches of medicine, clinical pharmacy is still in its infancy, with much room for growth, improvement, and recognition by both the medical community and patients. In this study, a widely-recognized development strategy analysis tool, Strength, Weakness, Opportunity and Threat [SWOT], was used to systematically address several key issues to the development of clinical pharmacy in China. This analysis aims to provide feasible recommendations for the development of clinical pharmacy in China by identifying current problems and growth opportunities. Full development of clinical pharmacy as a mature clinical discipline will help promote the rational use of drugs by both clinicians and patients and lead to enhanced drug efficacy and safety

ABSTRACT

Objective:To observe the effect of Gemcitabine ( GEM) on the viability and apoptosis of non-small cell lung cancer HCC827 in vitro. Methods:The cell viability,apoptosis and cell cycle of HCC827 cells induced by Gemcitabine were detected with cell counting kit-8 assay (CCK-8),Annexin V-FITC/PI staining and flow cytometry. The expression of Bcl-2 protein of cells treated with GEM was examined by Western blot assay. Results: There was significant inhibition effect on HCC827 cells treated with 0. 1-1 000 ng/ml of GEM,which can promote the occurrence of HCC827 cell apoptosis and arrest cell in the S phrase. The apoptosis induced by GEM was accompanied with the down regulation of Bcl-2 protein. Conclusion: GEM can inhibit the cell viability and induce the HCC827 cell apoptosis and S phrase arrest. Its cell dead type was apoptosis,which was related with the expression of Bcl-2 protein.

ABSTRACT

Objective To explore the regulatory effects of HTLV-1 ( human T-cell leukemia virus type 1 ) Tax protein on the expression of HMGB 1 ( high mobility group box 1 ) gene in T cells .Methods Total RNA and protein were extracted from Tax +-T cells ( TaxP ) , Tax--T cells ( TaxN ) and Jurkat cells which were stably transfected with pCMV-Tax and pCMV-Neo, respectively.Then, the expression levels of HMGB1 mRNA and protein in different CD 4+T cells were analyzed by real-time PCR and Western blot (WB).By using liposome-mediated method, pGL3-HMGB1-luc reporter genes and pGL3-neo-luc were tran-siently transfected into TaxP and TaxN cells and the basal transcriptional activity was observed in different T cells.Additionally, pCMV-Tax and pGL3-HMGB1-luc reporter genes were also co-transfected into Jurkat cells and the regulatory effects of Tax protein on HMGB 1 gene was detected .The chromatin immunoprecipi-tation (ChIP) assay was used to identify HMGB1 genomic sites directly targeted by Tax .Results The ex-pression levels of HMGB1 mRNA and protein in Tax+-T cells ( TaxP) were higher than those in Tax--T cells (TaxN).The transcription regulation trends for HMGB1 gene in TaxN and TaxP cells were similar but not identical in diverse T cells.pHLuc3 (containing -504-+83 HMGB1) showed the highest transcriptional ac-tivity of HMGB1 gene in both TaxP and TaxN cells , but HMGB1 transcriptional activity of pHLuc 6 in TaxP cells was significantly stronger than that in TaxN cells .Luciferase assays also showed that Tax protein promo-ted the transcription of HMGB1 gene in a dose-dependent manner .The ChIP assay further confirmed that Tax protein enriched at the HMGB1 region of -1163--1043.Conclusion The region of nt -504--383 is essen-tial for the basal promoter activity of -1163-+83 HMGB1 gene originated from pHLuc 6 reporter plasmid , and Tax protein enriched probably at the HMGB 1 site of -1163--1043 enhances HMGB1 transcription.

ABSTRACT

BACKGROUND: The abnormal changes of hemorrheologic indexes are closely correlated with vascular injury, disorder of microcirculation, thrombosis and its development.OBJECTIVE: To investigate the changes of 25 indexes of hemorheology and whole hemocytes in patients with acute cerebral infarction.DESIGN: A controlled case study.SETTING: Department of Medical Laboratory, Xinxiang Medical College.PARTICIPANTS: Cerebral infarction group: Totally 127 patients with the first attack of acute cerebral infarction were selected from the Department of Neurology, the Second Affiliated Hospital of Xinxiang Medical College from January to December in 2002. The onsetof disease ranged from 4 to 12 hours, and the lesions were confirmed by cranial CT, the diagnostic standard accorded with the diagnostic guidelines for various cerebrovascular diseases formulated by the Fourth National Academic Conference for Cerebrovascular Diseases. Normal control group: Fifty-three healthy physical examinees with normal blood pressure and without diseases of heart,brain and kidney, as well as diabetes mellitus. There were no sigmficant differences in ages and male to femaleratios between the two groups.METHODS: ① Patients in the cerebral infarction group received fibrinogen reduction therapy, they were injected with two pieces of 10 u defibrin on the day of admission, and injected with one piece of 10 u defibrin again on the 3rd, 5th and 7th days respectively. ② Fasting venous blood (5 mL) was drawn with thromboliquine anticoagulated vacuum blood collecting tube,and 2 mL blood was coagulated with EDTA-K2. The whole blood viscosity,whole blood high-sheafing reduction viscosity, whole blood low-shearing reduction viscosity, whole blood high-sheafing relative index, whole blood lowsheafing relative index, equation K value of erythrocyte sedimentation, plasma viscosity, hematocrit, erythrocyte sedimentation, aggregation index of red blood cells (RBC), rigidity index of RBC, deformation index of RBC, counts of while blood cells (WBC) and RBC, mean volume of RBC, mean corpuscular volume (MCV), RBC distribution width (RDW), content of hemoglobin,mean corpuscular hemoglobin content (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet count, mean platelet volume (MPV) and platelet distribution width (PDW) were detected when the shear rate was 200 s-1, 30 s-1, 5 s-1 and 1 s-1 respectively. ③ The above indexes of the patients with cerebral infarction were detected within 24 hours after attack (exacerbation) and at two weeks after treatment (recovery period) respectively.MAIN OUTCOME MEASURES: The hemorrheologic and whole hemocyte indexes were compared between the two groups.RESULTS: All of the 127 cases in the cerebral infarction group entered the analysis of results at exacerbation, and 5 of them were not reexamined because of discharge and 122 cases entered the analysis of results at recovery period. All the 53 cases in the normal control group were involved in the analysis of results. ① Except RDW and MCHC, all the other indexes in the patients with cerebral infarction at exacerbation were significantly different from those in the normal control group (P<0.05, 0.01). As compared with the normal control group, the whole blood low-shearing viscosity, whole blood low-shearing reduction viscosity, whole blood high-sheafing relative index, whole blood low-shearing relative index, plasma viscosity,hematocrit, aggregation index of RBC, WBC count and MCH all returned to normal in the patients with cerebral infarction at recovery period (P>0.05).② As compared with the exacerbation, the RBC count and MPV were obviously decreased in the patients with cerebral infarction at recovery period (P < 0.05), while the other indexes were similar (P > 0.05).CONCLUSION: Abnormalities of hemorrheologic indexes commonly exist in patients with acute cerebral infarction, which indicates that the abnormalities of hemorrheologic and whole hemocyte parameters may be related to the occurrence of acute cerebral infarction.
