To cultivate more excellent pharmacists, ensuring patients rational drug use, standardiza-tion training of hospital pharmacists in Beijing has been carried out since 2000, and the wonderful effect has been achieved. The teaching methods mainly include centralized training model, small lectures, practice teaching and self-study. The training teaching content mainly includes prescription audit, drug dispensing and management as well as the pharmaceutical care. In this paper, based on the analysis of the status quo, it is recommended that detailed training formulate, teaching methods and content of the second stage of the training about the training management policy, and the clinicians teaching should be added to the contents of teaching. The thought moral qualities, laws and regula tions, as well as academic and research training should also be added to the teaching content.

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.

CONCLUSIONS According to canonical scientific management,to favor the quality and safety of infection prevention in operating room.

Objective To investigate the effects of pentoxifylline on the cell proliferation of, collagen synthesis and TGF-β1 expression by human fibroblasts derived from keloid. Methods Skin samples were obtained from the lesions of 3 patients with keloid and normal skin of 3 human controls followed by primary culture of fibroblasts. Fibroblasts of 5th to 8th generation were cultured with pentoxifylline of 0.1 to 3 g/L for various durations. Then, MTT assay was performed to detect the cell proliferation of fibroblasts, double antibody sandwich-enzyme linked immunosorbent assay (ELISA) to measure the expression of TGF-β1, and reversetranscription PCR to examine the mRNA expressions of procollagen Ⅰ and Ⅲ in these fibroblasts. Results The pentoxifylline of 0.1 to 2 g/L markedly inhibited the proliferation of fibroblasts derived from keloid lesions and normal skin, in a dose- and time-dependent manner, with the strongest effect observed in fibroblasts treated with pentoxifylline of 2 g/L. A significant reduction was induced in the TGF-β1 mRNA expression in keloidand normal skin-derived fibroblasts by pentoxifylline of 0.5 to 2 g/L (all P < 0.01), and in the mRNA expression of procollagen Ⅰ and Ⅲ by pentoxifylline of 1 and 2 g/L (P < 0.05 or 0.01). Concretely, the relative mRNA expression level of procollagen Ⅰ and Ⅲwas 0.873 ± 0.077, 0.571 ± 0.050 respectively in keloid fibroblasts respectively, and 0.473 ± 0.035, 0.370 ± 0.045 in the control fibroblasts, after treated with pentoxifylline of 1 g/L, 0.750 ± 0.036 and 0.433 ± 0.045 respectively in keloid-derived fibroblasts, 0.390 ± 0.030 and 0.250 ±0.123 respectively in the control fibroblasts, after treated with pentoxifylline of 2 g/L, significantly lower than that in the keloid-derived (1.216 ± 0.061 and 0.953 ± 0.060) and control (0.836 ± 0.080 and 0.776 ± 0.041) fibroblasts without treatment. Conclusion Pentoxifylline shows an evident suppressive effect on the cell proliferation of, as well as the expression of TGF-β1 and procollagen Ⅰ and Ⅲ in fibroblasts derived from keloid lesions and normal skin.

BACKGROUND:In recent years,pentoxifyIline has been found to have a wide range of anti-fibrosis capacity However,there are few studies explore the suppress effect of pentoxifyIline on fibroblasts in human keloid.and the maximum inhibitory concentration remains poorly understood.OBJECTIVE:To study the effect of pentoxifyIline on proliferation activity of human keloid fibroblasts and to select the maximum inhibitory concentrationMETHODS:Human keloid fibroblasts were used as original cells,passaged till the 5~(th) to the 8~(th) generations.and then divided into the experimental and control groups.PentoxifyIline with concentrations of 0.1,0.25,0.5,1.0,2.0 and 3.0 g/L were added to the experimental group.The effects of different concentrations of pentoxifylline on proliferation of keloid fibroblasts were detected by MTT chromometry.RESULT AND CONCLUSION:Compared with the control group,the inhibitory effect of pentoxifylline on the proliferation of keloid fibroblasts was more evident in the experimental group(P＜0.05)The inhibition rates of pentoxifylline on proliferation of keloid fibroblasts showed apparently time-and dose-effect relationships within the concentration of 0.1-2.0 g/L.which presented a greatest level at 96 hours after culture.The maximum inhibitory rate was 53 37%,and the concentration was 2.0 g/L in the experimental group.Consequently,pentoxifyIline plays a notable inhibitory role in the proliferation of human keloid fibroblasts with concentration of 2.0 g/L at 96 hours after culture.

Objective To study the association between serum interleukin-33 (IL-33) level and human stromelysin-2 (ST2) level in patients with rheumatoid arthritis (RA) associated with interstitial lung disease (RA-ILD) and its correlation with lung function and other laboratory parameters.Methods Two hundred and forty-five newly diagnosed RA patients during March 2012 to March 2013 in the in-patient and out-patient clinic of the First Affiliated Hospital of Liaoning Medical College were enrolled into this study.Patients were further divided into RA group (n=187) and RA-ILD group (n=58).Sixty subjects who came to the hospital for routine health check-up was composed of the normal control group.The clinical data of the two groups and controls were collected and their serum IL-33 and ST2 concentrations were measured.The t test was used to compare the difference between the two groups.Multiple variance analysis was used to com-pare the difference between groups.Pearson's correlation analysis was applied to explore the relationship between IL-33 concentrations and related variables.Results ① This study showed that the prevalence of RA associated interstitial lung disease was 23.7％(58/245).② The concentration of IL-33 [(746±43) pg/ml] and ST2 [(3413±169)pg/ml] of the RA-ILD group was significantly higher than that of the RA group [(433±42) pg/ml,(1500±147) pg/ml] (P＜0.01).③The vital capacity (VC％),forced vital capac-ity (FVC％),maximal midexpiratary flow curve (MMF％) and carbon monoxide diffusing capacity (DLCO) of the RA-ILD group were significantly lower than those of the RA group.④ The serum level of IL-33 was negatively correlated with that of RF and ACPA (IL-33 and RF,r=0.82,P＜0.01; IL-33 and ACPA,r=0.55,P＜0.01).Serum level of IL-33 was negaitively correlated with DLCO (r=-0.80,P＜0.01).Conclusion IL-33 participates in the pathogenesis of RA; and may be involved in the pathogenesis of RA-ILD.

Objective To reveal the role of PDK1 in vascular endothelial cells. Methods PDK1 was knocked out in endothelial cells by recombinase-mediated Cre to observe it′s effects on vascular endothelial cells. Results Abnormality of vascular development in rats could be found as a result of endothelial PDK1 deletion. Meanwhile, vascular leakage and bleeding phenotype were observed, and tissue analysis showed vascular endothelial cells abnormalities. Conclusions PDK1 plays an important role in the functioning and integrity of vascular endothelial cells, which made tentative explanation for PDK1-Akt signal path and laid basis for further research.
