Research Progress of CD4 / 中国医学科学院学报

Neurodegenerative diseases are associated with neuroinflammation,oxidative stress,and aging,which can lead to cognitive and motor dysfunctions.Recent studies suggest that the development of neurodegenerative diseases is related to adaptive immunity,in which CD4

Regulation of mitochondrial carrier slc25a13 on breast cancer cell cycle in vitro / 上海交通大学学报（医学版）

Objective:To investigate the role of mitochondrial solute carrier family 25 member 13 (SLC25A13) on breast cancer development. Methods:SLC25A13 mRNA and protein expressions in invasive breast cancer tissues and normal breast tissues were from The Cancer Genome Atlas (TCGA) breast cancer dataset. Survival analysis was conducted online by Kaplan-Meier software. MCF-7 cell line was used for in vitro cell assay. Knockdown of SLC25A13 and sirtuin 2 (SIRT2) were conducted by siRNA transfection. Cell viability was measured with trypan blue exclusion. Cell cycle arrest was determined by flow cytometry. The mRNA expression of SLC25A13 and P27 were detected by quantitative PCR. The protein level of SLC25A13, P27 and SIRT2 were detected by Western blotting. Protein half-life of P27 was assessed by Western blotting after cycloheximide treatment. Results:SLC25A13 was up-regulated in invasive breast cancer tissues. High expression of SLC25A13 correlated with poor overall survival and breast cancer recurrence. SLC25A13 knockdown inhibited MCF-7 cell cycle progression. P27 and SIRT2 both accumulated after SLC25A13 knockdown. P27 accumulation resulted from prolonged protein half-life. Knockdown of SIRT2 restored cell cycle arrest as well as P27 accumulation caused by SLC25A13 silencing. Conclusion:High expression of SLC25A13 may promote cell cycle progression via SIRT2 in breast cancer development.

Effects of ulinastatin on cognitive function in patients with coronary artery bypass grafting / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the effects of ulinastatin(UTI) on postoperative cognitive function in patients undergoing coronary artery bypass grafting.</p><p><b>METHODS</b>One hundred and twenty-seven patients undergoing elective coronary artery bypass surgery were randomly divided into three groups:high-dose UTI group(16000 U/kg i.v.), low-dose UTI group(8000 U/kg i.v.) and control group(normal saline). The levels of plasma cortisol were measured before and one day after surgery. The level of IL-6, IL-10, TNF-α and S100β were measured before operation(T0), at open chest(T1), end of operation(T2), 6 h(T3)and 24 h(T4) after operation. A neuropsychological test scale was to evaluate the cognitive function 1 day before operation, 1 week and 3 months after operation.</p><p><b>RESULTS</b>Ninety-three patients completed the study. There was no significant difference in general information of patients among three groups(P>0.05). The level of plasma cortisol one day after operation was significantly higher than that before operation in control group(P<0.01). The levels of plasma cortisol in high-dose UTI group and low-dose UTI group were lower than that of control group(P<0.01). In all groups, the level of plasma IL-6, IL-10, TNF-α and S100B increased remarkably at T2, T3, T4 compared to those at T0(all P<0.05). The level of plasma IL-6, TNF-α(at T2, T3, T4)and S100β(at T3)in high-dose UTI group and low-dose UTI group were all lower than those of control group(P<0.05),while there were no significant differences between high-dose UTI group and low-dose UTI group(P>0.05). The incidence of postoperative cognitive dysfunction in POCD 1 week after operation in high-dose UTI and low-dose UTI groups(25.8% and 23.3%)was lower than that in control group(50.0%), while there were no significant difference 1 month after operation between high-dose UTI group(12.9%) or low-dose UTI group(16.7%)and control group(28.1%). The level of plasma S100β at T2 of POCD patients(n=31)was higher than that of non-POCD group(n=62)(P<0.05).</p><p><b>CONCLUSION</b>Ulinastatin can reduce the incidence of postoperative cognitive dusfunction 1 week after coronary artery bypass surgery, which might be associated with inhibition of inflammation and S100β expression.</p>

Effects of male reproductive health information education communication on mastering STDs knowledge among young couples / 中华男科学杂志

<p><b>OBJECTIVES</b>To increase the knowledge of STDs control and prevention among young couples by intervention, and to improve their reproductive health.</p><p><b>METHODS</b>The intervention plan was made and carried out on the basis of the information from baseline interview and Focus Group Discussions. The activities of the intervention included lectures given by experts, counseling service, delivering knowledge foldouts and knowledge competition. The final survey was conducted. The data of baseline and final survey were analyzed with SAS software.</p><p><b>RESULTS</b>Before intervention, young couples knowledge of STDs was similar between the experimental and the control group. After intervention, proportion of knowing numbers of STDs kinds in experiment group significantly was higher than that in control group(P < 0.01); The proportion of knowing harm of STDs and knowing to use consom to prevent STDs couples were significantly higher in experiment group than that in control group(P < 0.01).</p><p><b>CONCLUSIONS</b>The intervention activities including lectures and counseling services were positive and great sociological affects on family planning and reproductive health improvement for young couples which has one child.</p>
