Objective:To explore the future development of pharmacists. Methods:The combination of on-site and mailed ques-tionnaire was adopted to investigate the present work situation of pharmacists in hospitals at different levels in 15 provinces and munici-palities of east China. Based on the statistical analysis of data, some problems in the present work of pharmacists were investigated. Results:The data showed that there was a wide gap of human resource among the hospitals at different levels, and the working condi-tion improvement for pharmacists should be performed. Continuing education and legislation were not standardized and unified yet, and the clinical pharmacy and the rational drug use needed further development. Conclusion:The relevant laws and regulations should be established and improved to guarantee the lawful right and interests of pharmacists. The pharmacist training system should be improved to raise the professional quality of pharmacists and promote the development of hospital pharmacy.

Methamphetamine is a powerful stimulant of amphetamine type in the central nervous system (CNS),and recently it has become the major drugs of abuse.A lot of research results show that MA may induce dopaminergic neurotoxicity in the animal and human striatum.The mechanisms include effects on dopaminergic signaling and dopamine oxidation,glutamate induced excitotoxicity,oxidative stress and inflammatory cytokines,disruption of mitochondfia,apoptosis,activation of glial cells and hyperthermia.However the mechanisms by the MA-induced dopaminergic neurotoxicity are not completely understood.The paper reviewed recent progress of study on them to provide reference materials for related research.

AIM:To explore if there is lesion in the auditory path in the brainstem of the Wistar rat with experimental autoimmune encephalomyelitis(EAE).METHODS:EAE was induced by guinea pig spinal cord homogenate(GPSCH),then the evoked potential in both EAE and control groups was examined.The HE staining and myelin staining of the auditory nucleus were conducted in order to corroborate the damage of the auditory path in the brainstem.Through studying the pathological changes using light microscopy and behavior changes of rats,we defined that the model was successful.RESULTS:The latency period of auditory evoked potentials of EAE rats was much longer than that in control group.The pathological pictures manifested that auditory nucleus were invaded by a great number of lymphocytes,demyelinations were discovered in it.CONCLUSION:The auditory path in the brainstem of the Wistar rat with EAE is suffered from inflammation and demyelination.

ObjectiveTo inyestigate the effect of miRNA-155 expression on the differentiations and functions of CD4 + T lymphocyte in patients with unstable angina pectoris. MethodsTwenty-one patients with unstable angina pectoris (UAP) were enrolled in this study, and another 18 patients with normal coronary arteries evidenced by angiography were assigned as control group. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expression of miRNA-155 in CD4 + T lymphocyte of the peripheral blood. And the levels of IFN-γ and IL-4 in serum were determined by using enzyme-linked immunosorbent assay (ELISA). The CD4 + T lymphocyte were isolated from mononuclear cells prepared with Ficoll-Hypaque density-gradients centrifugation from human peripheral blood by magnetic cell sorting system. Then, the CD4 +T cells (2 × 106 cells/mL) were seeded in culture plates with 6 wells.The CD4 + T lymphocytes were divided into 3 groups in experiment: control group, miRNA-155 group, and miRNA-155 inhibitor group. The numbers of Th1 and Th2 cells were measured by flow cytometry analysis (FACS).The protein levels and expressions of IFN-γRα, T-bet, GATA-3 mRNA were measured by using western blotting and qRT-PCR, respectively. The levels of IFN-γ and IL-4 in culture supernatants of CD4 +T lymphocytes were detected by using ELISA. ResultsIn comparison with the control group, there was significant increase in the expression of miRNA-155 and serum level of IFN-γ in the UAP group (P ＜0. 01 ). There was a positive correlation between miRNA-155 and serum IFN-γ ( r =0. 842, P ＜ 0. 0l ).However, in vitro, the number of Th1, the protein level and expression of T-bet mRNA, and supernatant IFN-γ increased, and the protein level and expression of IFN-γRα protein decreased in miRNA-155 group in comparison with the control group (all P ＜0. 01 ). Interestingly, there were no significant differences in the number of Th2 cells, the expressions of GATA-3mRNA and IFN-γRα mRNA, GATA-3 protein and supernatant IL-4 between control group and miRNA-155 group ( all P ＞ 0. 05 ). And the miRNA-155 inhibitor could attenuate the effect of miRNA-155 effectively. ConclusionsThe miRNA-155 can promote differentiations and improve the function of Thl, playing an important role in the pathogenesis of unstable angina pectoris.

Objective To observe different effects of cyclic and continuous nutrition infusion on serum nutritional indicators, peripheral white blood cell counts (WBC), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ ) score in patients with mechanical ventilated respiratory failure (MVRF).Methods A cross-over and self-controlled trial was conducted in 48 patients with MVRF treated in a medical intensive care unit during December 2006 to June 2009, and continuous nutrition (group A) and cyclic nutrition (group B) were infused respectively for patients of the two groups.Serum levels of albumin (ALB), pre-albumin (PA), transferrin (TR), PaO2, PaCO2, WBC and APACHE Ⅲ score were measured for the patients with 24-hour continuous nutrition (group A) and 16-hour cyclic nutrition (group B)infusion.Effects of the two nutritional therapies were compared.Results After nutrition infusion, serum levels of ALB, PA and TR were (34±3)g/L, (196±28)mg/L and (2.1±0.3 ) g/L in group A, and (35 ±4) g/L, (198 ±25) mg/L and (2.0 ±0.4) g/L in group B, respectively; and PaO2 and PaCO2levels were (92 ± 12) mm Hg ( 1 mm Hg =0.133 kPa) and (42 ± 10) mm Hg in group A, and (91 ±9)mm Hg and (42 ± 10) mm Hg in group B, respectively.WBC and APACHE Ⅲ score were ( 11.8 ± 1.7) ×109/L and 38 ±7 in group A, and ( 12.6 ± 1.2) × 109/L and 40 ±6 in group B, respectively.Significant difference in serum levels of PA and TR was found between the two groups (PPA =0.019 and PTR =0.013),while there was no significant difference in other indictors between the two groups.Conclusions 24-hour continuous nutrition infusion for patients with MVRF can obviously improve their serum levels of PA and TR,but has no effect on serum level of ALB, PaO2, WBC and APACHE Ⅲ score in critical ill patients, as compared to those with 16-hour cyclic nutrition infusion.

ObjectiveTo probe into the ultrasonic(US) predictive value for metastasis of the cervical lateral lymph node(LNM) with the preoperative ultrasonic examination in thyroid papillary microcarcinoma (PTMC),then,to further evaluate the significance of the preoperative ultrasonic score (US) for predicting metastasis of the cervical lateral lymph node.Methods From May 2004 to May 2011,165 patients diagnosed as PTMC (the ultrasonic imaging of lymph node showed no lateral LNM) were retrospectively analyzed and the US and final pathological data from the cases were collected to determine the relevant factors and different scores.ResultsThere were significant differences(P ＜ 0.05 )among US characteristics of microcalcification,no well-defined margin,tumor located at the upper pole,the perimeter of the tumor contacted with the adjacent capsule of thyroid being ＞25 ％ and the presence of the cervical lateral lymph nodes metastasis in PTMC between the metastatic group and the non-metastatic group.The total scores of the ultrasonic ≥2.5 was the delimitation value,its sensitivity was 86.2％ and its specificity was 89.7％.ConclusionsThe ultrasonic score has definite value in the differential diagnosis for the metastasis of the cervical lateral node in the patients of no lateral LNM,when the ultrasonic score is larger than 2.5,the possibility of the cervical lateral lymph node metastasis should be noticed.

Objective To investigate the relationship between the methylation of CpG island of RUNX3 gene promoter and its expression in a human cutaneous malignant melanoma cell line A375, and to assess the role of RUNX3 gene methylation in the pathogenesis of human cutaneous malignant melanoma. Methods Cultured A375 cells were treated with various concentrations (0, 1, 5, 10, 20 μmol/l) of 5-azacyti-dine for 24 or 72 hours followed by another 5 days of culture. Then, methylation-specific PCR (MSP) was performed to evaluate the methylation status of RUNX3 promoter region, and Western-blot analysis to detect the protein expression of RUNX3 in A375 cells. Results The RUNX3 gene promoter region was hypermethylated in untreated A375 cells, along with the absence of protein expression of RUNX3. However, after the treatment with 5-azacytidine, the promoter region of RUNX3 gene was demethylated partly, and the expression of RUNX3 protein was restored in A375 cells. Further, the expression intensity was directly correlated with the concentration of 5-azacytidine. Conclusions The promoter hypermethylation of RUNX3 gene may be related to the silencing of RUNX3 gene expression in A375 cells, whereas 5-azacytidine can cause the demethylation of RUNX3 gene, reactivate the gene which has been inactivated by the promoter hypermethylation, and finally induce the re-expression of RUNX3 protein.

AIM: In order to study the relationship between the ERK and p38 MAPK activation and the protection of 11, 12-epoxyeicosatrienoic acid (11, 12-EET) and ischemia preconditioning (IP), the effects of 11, 12-EET and ischemic preconditioning on phosphorylated ERK and p38 MAPK during ischemia and reperfusion in rat myocardium were examined. METHODS: The rat heart was subjected to ischemia for 5 min by ligating the left anterior descending coronary artery followed by reperfusion for 5 min (two times) to undergo ischemia preconditioning. The rats were divided into 5 groups: (1) control; (2) sham group; (3) ischemia/reperfusion (I/R) group, in which the rat heart suffered from 60 min ischemia followed by 30 min reperfusion; (4) IP plus I/R group; (5) EET plus I/R group, in which 6.28?10 -8 mol/L 11, 12-EET was injected intravenously 20 min before I/R. The heart function was examined, and phosphorylated ERK and p38 MAPK were detected by Western blot. RESULTS: At 30 min reperfusion, +dp/dt max ,-dp/dt max and LVDP decreased significantly in I/R group compared with sham group, IP plus I/R group and EET plus I/R group; Phosphorylated ERK1/2 level was higher in I/R group than sham group, but was lower in I/R group than IP plus I/R group and EET plus I/R group; Phosphorylated p38 MAPK level was lower in control, sham, IP plus I/R and EET plus I/R group than I/R group. CONCLUSION: 11,12-EET protects rat heart against ischemia/reperfusion injury, the mechanism may be related to activation of ERK1/2 and inhibition of p38 MAPK. [
