Objective To investigate the effect of cimetidine on the clonal expansion of TCR V? subfamily of T cells in cord blood after the stimulation by K562 cells in vitro.Methods Cimetidine(1?10-5 mol/L) or K562 cells(1?106/ml) or both of them were respectively cultured with mononuclear cells(MNC) isolated from normal human cord blood for 2 weeks.After the induction,specific cytotoxicity of the proliferated T cells were detected with K562 cells as the target cells.The selective usages and clonal expansion of TCR V? subfa-mily of T cells were analyzed by RT-PCR and genescan technique.Results After induction for 2 weeks,the 3 groups showed the increased cell proliferation,in which specific cytotoxicity of T cells induced by both cimetidine and K562 cells against K562 cells was enhanced significantly compared with the other 2 groups(P

Objective To study the repair function of united endothelial progenitor cells (EPC)transplantation on injured liver endothelium by bone marrow transplantation (BMT) conditioning.Methods C57BL/6 mice were divided into four groups randomly: normal control group, without any treatment; irradiation alone group, administered a total body irradiation(TBI) pretreatment, without BMT; (3) BMT alone group: C57BL/6 mice were infused with bone marrow mononuclearcells (MNC) 5 × 106/only through caudal vein not more than 4 h after the same TBI pretreatment as the irradiation alone group; united transplantation group: receiving the same way as the BMT alone group, but C57BL/6 mice were infused with EPC 5 × 105/only at the same time. Two, 4, 7, 14, and 21 days after the TBI, the changes of the liver weight were observed regularly. The histopathological examination of liver was done at the 4th, 7th, 14th, and 21st day after the TBI. Results In irradiation alone group, BMT alone group and united transplantation group the liver weight began to increase significantly on the day 2 and peaked at 14th day after the TBI, and the peaks were respectively (1.65±0. 15) times (P＜0. 05), (1.61 ±0.06) times (P＜0.05), and (1.11 ±0.40)times (P＜0. 05) of those in normal control group. At the day 14, the liver weight in irradiation alone group, BMT alone group and united transplantation group began to decrease, and on the day 21 the liver weight in united transplantation group had been completely restored to normal level, however the liver weight in irradiation alone group and BMT alone group were still significantly heavier than that in normal control group (P＜0. 05). Liver histopathological examination revealed that there were obvious sinusoidal endothelial cells (SEC) injury, hepatocyte edema and severe inflammatory cell infiltration in irradiation alone group, and on the day 7 the hepatocyte edema and necrosis were significantly worse than before, and almost no alive SEC were found. On the day 14 the injury of SEC in BMT alone group was lighter than before, but on the day 21 the injury had not returned to normal. On the day 7 the injury of SEC, hepatocyte edema and necrosis were alleviated in united transplantation group as compared with irradiation alone group and BMT alone group, and on the day 14 the injury had returned to normal basically. Conclusion The transplantation conditioning could damage recipient liver endothelium and the injury would persist, and united EPC infusion could repair the injured SEC following BMT.

Objective To study the relationship between graft-versus-host disease (GVHD) and endothelium injury following hematopoietic stem cells transplantation in mice. Methods C57BL/6 mice as donors and Balb/c mice as recipients were randomly divided into 4 groups: control group, bone marrow transplantation group, GVHD group, GVHD mitigation group. The clinical manifestations,circulating endothelial cells and tissue pathological changes were observed at different time points after transplantation. Results No manifestations of GVHD were found in each group at the day 5, while those were found in GVHD group at the day 9 and all died within 15 days. The counts of endothelial cells in peripheral blood showed no significant difference at the day 5 between GVHD group (7. 34 ±1.26 cells/μl) and bone marrow transplantation group (11.51 ± 7. 40 cells/μl) or GVHD mitigation group (7. 36 ± 0. 16 cells/μl), while among three groups there was statistically significant difference at the day 9 (GVHD group: 153. 64 ± 35. 35 cells/μl vs bone marrow transplantation group: 10. 49 ±5. 61 cells/μl and GVHD mitigation group: 47. 82 ± 4. 69 cells/μl). The scores of pathological aGVHD had no significant difference at the day 5 between GVHD group (4. 33± 1. 53) and bone marrow transplantation group (3. 33 ± 0. 58) or GVHD mitigation group (4. 00 ± 1.73), while among three groups there was statistically significant difference at the day 9 (GVHD group: 10. 0 vs bone marrow transplantation group: 3. 33 ± 1.15 or GVHD mitigation group: 4. 33 ± 0. 58) and at the day 14 (GVHD group: 10. 33 ± 2. 58 vs bone marrow transplantation group: 2. 33 ± 1.25 or GVHD mitigation group 3. 33 ± 1.15). Conclusion Occurrence of GVHD causes endothelial damage again and injured endothelium worsens the GVHD.

Two sample pretreatment methods of pesticide residues in Panax notoginseng of Chinese traditional medicine were developed. For Method I, the residues were extracted from homogenized tissue with n-hexane-dichloromethane (6:4) by means of ultrasonication, the crude extract was purified by an Envi-carb/NH2 solid-phase extraction (SPE) column. For Method II, matrix solid-phase dispersion (MSPD) technique was used for extracting and cleaning up. The eluates were concentrated by rotary evaporation, and then were redissolved in dichloromethane prior to GC-MS determination. The determination was performed in selected ion monitoring (SIM) mode with the external calibration for quantitative analysis. Under the optimal conditions, the results indicated that the methods are easier and faster, the recoveries of method I for the spiked standards at concentration of 0.01, 0.5, and 2.0 mg x kg(-1) were 81.90%-102.10% with the relative standard deviations (RSDs) of 3.60%-7.10%. The recoveries of method II were 96.26%-104.20% with the RSDs of 3.52%-7.94%. The detection limits (S/N) for residues of pesticides were in the range of 0.48-1.34 ng x g(-1). The results indicated that these multiresidue analysis methods can meet the requirements for determination of residue pesticides and can be appropriate for trace analysis of residue pesticides in Panax notoginseng.

Objective:To know the work status of clinical pharmacy in medical institutions of Guizhou province. Methods:Ques-tionnaires were used to analyze the situation of clinical pharmacy in 108 medical institutions of Guizhou province. Results: A total of 246 questionnaires were taken back, and among the 231 valid questionnaires were received including gradeⅡor above hospitals. The main contents of clinical pharmacy work carried out in medical institutions included 7 aspects: pharmacists ’ participation in ward rounds, which accounted for 47. 11%; pharmacists’ participation in case consultation, which accounted for 16. 65%; pharmacists’ participation in teaching practice, which accounted for 38. 84%; pharmacists’ participation in prescription evaluation and analysis, which accounted for 72. 73%;pharmacists’ participation in antimicrobial drug monitoring and drug use evaluation, which accounted for 62. 37%;pharmacists’ participation in drug counsultation and education, which accounted for 58. 68%;pharmacists’ participation in adverse drug reaction monitoring and supervision, which accounted for 77. 32%. Conclusion:The development of clinical pharmacy in Guizhou province still lags behind, and the number of clinical pharmacists is insufficient, which can’ t meet the growing demand for personalized medicine. In particular, the development of clinical pharmacy is restricted by the limited pharmaceutical service. The cog-nition degree of pharmacist group in Guizhou province has been improved. However, the number and the service quality of clinical pharmacists need to be improved further.

Objective To systematically review the effectiveness and safety of pantoprazole ( PAN ) vs. ranitidine (RAN) for patients with gastroesophageal reflux disease (GERD). Methods PubMed,Medline,EMbase,The Cochrane Library and three Chinese literature databases (CNKI,VIP and Wan fang) were retrieveed.Randomized controlled trials (RCTs) which compared the clinical outcomes of PAN group vs. RAN group for GERD were included. Two reviewers independently screened literatures in accordance with the inclusion and exclusion criteria, extracted the data and assessed the methodological quality of included studies.Then,meta-analysis was performed using RevMan 5.2 software. Results A total of 8 RCTs involving 1 590 patients were included.The results of meta-analysis showed that the PAN group was significantly superior to RAN group in terms of the healing rates and the relief rates of chief symptom for GERD of gradeⅠ-Ⅲ. While there was no significant difference in the incidence of adverse events between the two groups [GradeⅠ,RR=1.17,95%CI (0.80,1.70),P=0.43;GradeⅡorⅢ, RR=0.76,95%CI (0.43,1.36);P=0.36]. Conclusion Current evidence indicates that,pantoprazole is more effective than ranitidine for GERD of grade Ⅰ-Ⅲ,but both treatments are safe and well tolerated.

OBJECTIVE: To provide reference for standardizing clinical pharmacist training.METHODS: According to actual situation in our hospital, a new clinical pharmacist training teaching method [lecture-based learning (LBL) -case-based learning (CBL) combination method] was created by integrating the training resources of clinical teaching and research department and extending teaching content. The comprehensive skills of trainees after training were compared between 2015 (traditional one-to-one teaching model) and 2016 (LBL-CBL combination method). RESULTS & CONCLUSIONS: In 2016, trainees are significantly improved in the ability to analyze (3. 8 score vs. 2. 8 score) and deal with clinical problems (2. 9 score vs. 2. 5 score) compared with those in 2015. LBL-CBL combination method can satisfy the demands of clinical pharmacists training in our hospital. Not only basic theory and clinical knowledge of trainees are improved, but also clinical thinking and comprehensive skill of trainees are strengthened by using LBL-CBL combination method. LBL-CBL combination method can be used in clinical pharmacists training and its usual tests, and contributes to the improvement of clinical pharmacist training teaching.
