ObjectiveTo investigate the expression and activity of histone deacetylase (HDAC) in prostate cancer.Methodshe pathological samples of 37 cases of PCa were collected. The mean age of the patients was 73 (53 - 88 ) years, the preoperative t-PSA was 81.69 ( 3.13 - 2000 ) ng/ml, Gleason score: 13 cases were ≤7, 24 cases were ＞7. Twenty-seven cases of BPH were set as controls. The mean age of the BPH patients was 69 (52 - 84) years, the preoperative t-PSA was 10.93 ( 1.11 - 55.07 ) ng/ml.Western blotting and colorimetric Assay kits were used to determine the HDAC expression and activity. The difference of HDAC activity in benign prostatic hyperplasia and prostate cancer was statistically analyzed.The correlation of the HDAC expression level and values of PSA and Gleason score was also assessed.ResultsHDACs were over-expressed in most cases of prostate cancer, the expression rates were HDAC1 :57％, HDAC2: 68％, HDAC3: 84％ and HDAC4: 73％, respectively. The HDAC activity (P ＜0.05)was significantly different between the prostate cancer and benign prostatic hyperplasia groups. The expression level of HDAC did not correlate with the values of PSA and Gleason score.ConclusionsHDAC was highly expressed and strongly active in prostate cancer. The results suggest that HDAC might be a potential target for the management of prostate cancer patients.

Objective: To analyze relationships between levels of 24 hour movement (physical activity, screen time and sleep) and childhood obesity in students aged 7-18 years. Methods: This study used data from students aged 7-18 years in the 2015 China health and nutrition survey, and assessed levels of physical activity, screen time and sleep based on the Canadian 24 hour Movement Guidelines for Children and Youth. Associations between levels of 24 hour movement and childhood obesity were assessed using multivariable Logistic regression models. Results: The overall rate of overweight and obesity was 21.56%. Proportions of students meeting the guidelines for physical activity, screen time, sleep and three behaviors combined were 24.84%, 38.69%, 57.08%, and 6.77%, respectively. After adjusting for age, sex, location of residence and nationality, students meeting the sleep guideline were less likely to be overweight and obese than those who did not(OR=0.73)， students meeting both sleep and screen time guidelines had a lower risk in overweight and obesity than those met neither guidelines(OR=0.58)(P<0.05). However, other behaviors and behavior combinations showed no significant associations with overweight and obesity. Conclusion Only a small proportion of students met all three 24 hour movement guidelines. Ensuring adequate sleep and limiting excessive screen time may be an important strategy for childhood obesity prevention and management.

Objective To explore the role of impulsivity in manic episodes of bipolar I disorder and cognitive impairment. Methods Sixty-one patients with bipolar I manic-episode ( study group) and 43 healthy volunteers (control group) were included in the study,and the cognitive function and impulsivity of the subjects were assessed using the MATRICS consensus cognitive battery (MCCB) and BIS-11 impulsivity scale (BIS-11). The differences in impulsivity and cognitive function between the study group and control group were compared. Partial correlation analysis was used to analyze the correlation between impulsivity and cognitive function in patients with bipolar I manic episode. Results ( 1) The scores of several cognitive function in study group,were significantly lower than those in healthy control group including information pro-cessing speed,attention alertness,word learning,visual learning,working memory,reasoning and problem sol-ving (all P<0. 01). (2)The total score,motor factor score and cognitive factor score of BIS-11 impulse scale in study group were significantly higher than those in control group (58. 39±15. 77 vs 48. 02±11. 16,62. 09± 19. 01 vs 44. 24±21. 09,56. 97±16. 57 vs 50. 06±13. 87,all P<0. 05). Increased overall scores on the bis-11 impulse inventory may be a risk factor for bipolar I episodes( OR=1. 204,95% CI=1. 032-1. 404). (3) In study group,the total score of BIS-11 was negatively correlated with the speed of information processing, working memory,word learning,reasoning and problem solving,and the total score of MCCB(r=-0. 417,-0. 360,-0. 294,-0. 348,-0. 348,P<0. 05). The score of unplanned factor was negatively correlated with the speed of information processing,word learning,the total score of MCCB(r=-0. 397,-0. 302,-0. 358,P<0. 05). The score of cognitive factor was negatively correlated with the speed of information processing,work-ing memory,word learning,reasoning and problem solving,and the total score of MCCB(r=-0. 327,-0. 351,-0. 374,-0. 391,-0. 463,P<0. 05). The score of motor factor was negatively correlated with working memo-ry and the total score of MCCB(r=0. 370,r=0. 389,P<0. 05). Conclusion High impulsivity is a risk factor for manic episodes of bipolar I disorder and may be associated with cognitive impairment in patients with ma-nic episodes of bipolar I disorder.

OBJECTIVETo investigate the effects of different subtypes IFN alpha (IFN alpha2b, IFN alpha2a, and IFN alpha1b) transduction molecular STAT1, STAT2, IFNAR, PKR, and RNase L, and to study the differences of their antiviral effects and to evaluate the key signaling transduction molecules.

METHODS(1) After HepG2 cells were treated with IFN alpha2b, IFN alpha2a, or IFN alpha1b, the mRNA levels of STAT1, STAT2, IFNAR, PKR, and RNase L were detected by RT-PCR. (2) After HepG2 cells were treated with 1000 U/ml IFN alpha2b, IFN alpha2a, or IFN alpha1b, the protein expression levels of STAT1 and IFNAR were examined by Western blot.

RESULTSRT-PCR results: (1) IFNAR, STAT1, and STAT2 mRNA expression levels were slightly higher in the IFN alpha1b group than those in the IFN alpha2b group (P > 0.05). The mRNA expression levels in IFN alpha1b or IFN alpha2b groups were significantly higher than in the IFN alpha2a group (P < 0.05). (2) The PKR mRNA expression showed no significant differences among IFN alpha1b, IFN alpha2b, and IFN alpha2a groups. (3) The RNase L mRNA expression was very weak. We could not compare the differences of the RNase L mRNA levels in different groups by RT-PCR. Western blot results: (1) The IFNAR, and STAT1 protein expressions were greatly up-regulated after IFN alpha induction compared with the untreated group (P < 0.05). (2) The IFNAR, and STAT1 protein expression levels in IFN alpha1b group were slightly higher than the IFN alpha2b group. IFNAR, and STAT1 protein levels of IFN alpha1b or IFN alpha2b group were significantly higher than IFN alpha2a group (P < 0.05).

CONCLUSIONSTAT1, STAT2, IFNAR mRNA and protein expressions could all be markedly up-regulated after IFN alpha treatment. Effects of IFN alpha1b or IFN alpha2b were greatly stronger than IFN alpha2a. The PKR mRNA expression also was greatly up-regulated after IFN alpha treatment. Expression levels of PKR in IFN alpha1b, IFN alpha2b, and IFN alpha2a groups were all similar. The mRNA level results were consistent with the protein level results. Our results showed that the antiviral activity of IFN alpha1b or IFN alpha2b were stronger than that of IFN alpha2a. The signal transduction molecules STAT1, STAT2, and IFNAR could be regarded as a key index to evaluate antiviral activity of IFN alpha. Further confirmation is still needed to see whether PKR could be regarded as a key index.
