Resveratrol is a natural polyphenolic compound. It possesses a variety of biological properties including neuroprotective effects, cardiovascular protection, anti-inflammatory and anti-cancer effects. In recent years, the anti-tumor effects of resveratrol have attracted a lot of attention. Its anti-tumor effects may be mediated by inhibiting tumor initiation, inhibiting tumor cell proliferation, promoting tumor cell apoptosis and inhibiting tumor cell invasion.

OBJECTIVE:To provide reference for rational use of glucocorticoid in the clinic. METHODS:The glucocorti-coid outpatient prescriptions collected from clinical departments of a hospital during Jan. 2013 to Jun. 2015 were analyzed statisti-cally in respects of glucocorticoid use,department distribution,DDDs,distribution of prescription diagnosis,etc. RESULTS:Of 15 000 prescriptions,there were 1 562 glucocorticoid prescriptions,with utilization rate of 10.4%;189 prescriptions were recog-nized as irrational ones,with irrational rate of 12.1%. The proportion of glucocorticoid in otorhinolaryngology department was the highest(27.66%),and irrational drug use was the highest in pediatrics department(16.12%);Dexamethasone injection was the most widely applied(44.88%);most of glucocorticoid prescriptions were used for acute bronchitis and bronchitis(267 pre-scriptions). CONCLUSIONS:The irrational glucocorticoid application has existed in the hospital,which deserved special atten-tion. Hence,prescription check and evaluation should be strengthened to promote the safety and efficacy of glucocorticoid in clini-cal application.

Objective To investigate the effect of miR-27a mimic and inhibitor on proliferation and apoptosis in melanoma cell line WM239. Methods The miR-27a mimic,inhibitor and its negative control were transfected into WM239 cells. The transfection efficiency was evaluated by fluorescence microscope. The expres-sion of miR-27a was detected by real-time fluorescent quantitative PCR. The proliferation of cells was detected by MTT. The cell apoptosis and cell cycle were analyzed by flow cytometry. Results The transfection efficiency in WM239 cells was 80% to 90%. The expression of miR-27a was markedly up-regulated in miR-27a mimic group (2-△△CT value is 26. 98 ± 0. 01),with statistically significant difference(t= -1 123. 67,P=0. 00);and the miR-27a inhibitor group showed lower expression of miR-27a(2-△△CT value is 0. 96 ± 0. 02),there was no statisti-cally significant difference compared with normal control group(t=0. 04,P=0. 06). The proliferation of cells was obviously inhibited in miR-27a mimic group,and there was statistically significant difference compared with normal control group[absorbance of 72 h(0. 45 ± 0. 02)∶(0. 72 ± 0. 01),F=129. 56,P﹤0. 05]. The percent-age of WM239 cells in G0-G1 phase was increased[(74. 83 ± 1. 46)∶(63. 73 ± 1. 25),F=30. 33,P﹤0. 05], and the percentage of WM239 cells in S phase and G2-M phase were decreased[(21. 33 ± 1. 75)∶(27. 50 ± 1. 25),F=14. 98,P﹤0. 05;(3. 90 ± 1. 31)∶(8. 80 ± 2. 10),F=3. 66,P﹤0. 05]. The apoptosis rate of cells was significantly increased in miR-27a mimic group compared with normal group[(29. 67 ± 0. 91)%∶(1. 44 ± 0. 85)%,F=530. 90,P﹤0. 01],but the inhibitor group had no obvious effect on cell cycle and cell apoptosis. Conclusion MiR-27a can suppress melanoma cell proliferation and act as a tumor suppressor gene,which is rel-evant to induce cell apoptosis and block cell cycle in G0-G1 phase.

Background and purpose:Loss of the tumor suppressor phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is one of the most common somatic genetic aberrations in prostate cancer in Western countries and is frequently associated with tumor progression and poor prognosis. This study aimed to investigate the frequency of PTEN protein loss in Chinese prostate cancer patients and to determine its association with the biochemical recurrence of prostate cancer.Methods:The data from 225 diagnosed localized prostate cancer patients with radical prostatectomy from 2006 to 2011 were collected retrospectively, including patient’s age at diagnosis, prostate-speciifc antigen (PSA) level at diagnosis, Gleason score, clinical stage, surgical margin, and time to biochemical recurrence or not. This study performed PTEN protein immunohistochemistry on tissue microarrays, which were made from 225 Chinese prostate cancer patients mentioned above, treated by radical prostatectomy with one case including 2 cancer spots and 2 adjacent normal gland spots. Correlations of PTEN loss with clinicopathological features were analyzed usingχ2 test. Kaplan-Meier survival model and Cox proportional hazards regression model were used to evaluate the predictive role of PTEN protein expression and patient characteristics for biochemical recurrence. Results:PTEN protein loss was observed in 15% of the patients and was associated with increased preoperative PSA levels (P=0.03) and old age (P=0.009). In univariate Kaplan–Meier analysis, the factors associated with the biochemical recurrence of prostate cancer included PSA levels (P=0.000 4), Gleason sum (P=0.019 8), and PTEN status (P=0.013 1). In multivariable Cox regression analysis, PTEN expression (HR=0.536, P=0.044), PSA levels (HR=1.879, P=0.001), and Gleason score (HR=1.361,P=0.03) were signiifcant in predicting biochemical recurrence of prostate cancer.Conclusion:PTEN protein loss is associated with an increased risk of recurrence, independent of known clinicopathological factors.

By retrospective analysis method, the paper was summarized experience of clinical pharmacy of TCM. The purpose of the paper was given location of clinical pharmacists in Traditional Chinese Medicine(TCM), to clear their main status and functions, seek methods and ways to solve the problems in the process of work. The work was proceeding orderly. Good results have been achieved. The clinical pharmacists of TCM participate in clinical rational use of drugs to change the service mode ofindirect service for the patients in the past with the patients, doctors and nurses so as to make better service for people's life and health of Chinese medicine.

Chemokine receptor 4 (CXCR4) belongs to G protein-coupled receptor superfamily.It can induce immune cells-directed chemotaxis,thus keeping their homeostasis.CXCR4 expresses on a variety of tissues and cells.In different tumors and at different stages of tumors,CXCR4 expression is significantly higher than that in normal tissues.CXCR4 plays an important role in tumor progression since it is involved in tumor cell proliferation,adhesion,invasion and metasta.

Toll-like receptor (TLR) is an important pattem recognition receptor (PRR) which partici pates in innate immunity and regulates adaptive immunity.TLR can be expressed in immune cells and malig nant tumors recognize conservative molecular structure,mediate response of inflammation,tissue injury and repair,which plays an important role in the process of tumor.Research results about some molecules and signal pathways of TLR demonstrate that it can act anti or pro-tumor dual functions,which has an extensive prospects in prevention and treatment of tumor.

OBJECTIVE: To investigate the mRNA and protein expression of MICA in laryngeal squamous cell carcinoma tissue and the Hep-2 cells. METHOD: Reverse transcriptase-polymerase chain reaction (RT-PCR) and Western-blot were used to detect the expression of MICA mRNA and protein levels in the Hep-2 cells and laryngeal cancer tissues. RESULT: The MICA mRNA showed higher expression in Hep-2 cells by RT-PCR. Compared with the control, the mRNA expression of MICA was significantly enhanced in laryngeal cancer tissues (t = 11.878, P < 0.01). The intensity of MICA expression is not related to the clinical stage of cancer. MICA protein demonstrated higher level expression by Western blot. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. CONCLUSION The MICA mRNA showed stronger expression in Hep-2 cells and laryngeal cancer tissues. The intensity of its expression is not related to clinical stage of cancer. The MICA protein expression was strong in Hep-2 cells. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. MICA may play an important role in laryngeal carcinoma process.
