Objective To inveatigate the expression and clinical significance of microRNA‐204(miR‐204) in human renal clear cell carcinoma(RCCC) .Methods 65 cases of resected RCCC tissue and corresponding normal tumor‐adjacent tissue were col‐lected and detected the expression level of miR‐204 by using qRT‐PCR .The correlation between the miR‐204 expression level and clilicalpathological features was statistically analyzed .The artificial miR‐204 mimics were adopted to stranfect into Caki‐1 cells ,then the Western blot was used to detect the expression of Bcl‐2 a as the downstream potential targets of miR‐204 and SIRT1 mRNA and protein .Results The expression level of miR‐204 in the RCCC tissue was significantly lowere than that in the normal tumor‐adjacent tissues (P<0 .05);the low expression of miR‐204 was significantly associated with the tumor size (>3 cm ,P<0 .05) , lymph node metastasis(P<0 .05) and advanced TNM stage(Ⅲ + Ⅳ ,P<0 .05) .Both the mRNA and protin expression in RCCC Caki‐1 cells were down‐regulated after transfection .Conclusion The expression of miR‐204 is down-regulated in the RCCC tissue and is related to the malignant clinicopathological features ,and miR‐204 may suppress the RCCC genesis and development through down‐regulating the expression of Bcl‐2 and SIRT1 .

Objective To explore effect of preoperative neutrophil/lymphocyte ratio (NLR) on the prognosis of patients with prostate cancer.Methods A total of 51 cases died included in our hospital as the died group, also included 124 patients survival patients served as survival group.Preoperative total prostate specific antigen (tPSA), free prostate specific antigen (fPSA), albumin, white blood cell (WBC), neutrophil count, lymphocyte count, Gleason score, and NLR were collected.Receiver operating characteristic (ROC) curve was drawn.The function of the index on prognosis was evaluated.Results The average age was 74.0 (9) years in the died group, and 73.6 (11.0) years in the survival group.Gleason score was 8 ~ 10.The patients were followed up for 10 ~ 36 months with a median follow-up time of 23 months.No significant differences in albumin and Gleason score were found between death and survival groups (P >0.05).However, the other major indexes had significant differences between two groups (P < 0.01).NLR area under curve (AUC) was 0.835.The NLR boundary value was 2.84, which was higher than the critical value of patients with poor prognosis.Conclusions NLR can predict the prognosis of patients with malignant prostate cancer as auxiliary index.Patients with NLR > 2.83 had poor prognosis.

In China,few research findings in basic medicine could be translated to clinical practice,which is known as the disconnection between basic research and clinical application.Such phenomenon is mainly due to lack of ability in translational medicine,particularly,lack of training in clinical research and translational medicine.Now the emergence of translational medicine has put forward new requirements for graduate education in medical school,and demanding that the patient-centered concept be strengthened.As the major force of scientific and technological innovation,graduate students should receive long-term systematic trainings and conduct original researches.In addition,advanced courses in clinical research and translational medicine should be offered to graduate students ;furthermore,translation research platforms should be built up for them so as to improve the capacity of scientific research and innovation.
