ABSTRACT
Objective To investigate the possible correlation between the monocyte chemoattractant protein-1 ( MCP-1 ) gene A-2518G single nucleotide polymorphism (SNPs) in the promoter region and acute coronary syndrome (ACS) in Chinese Han ethnic population of Sunan region,Methods This study was conducted with a case-control design in 484 ACS patients including 290 acute myocardial infarction (AMI)patients and 194 patients with unstable angina pectoris (UAP) and 346 control subjects ruled out coronary disease by coronary angiography (control group),including 166 patients with coronary atherosclerosis and 180 subjects without coronary stenosis.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for the detection of the A-2518G polymorphism in MCP-1 gene,and then thefrequency of genetype was statistically analyzed.Results There were AA,AG and GG genotypes of MCP-1 gene A-2518G polymorphism in the ACS group and control group.The two groups could be considered as a genetic equilibrium representative by Hardy-Weinberg equilibrium ( P ＞ 0.05 ).Compared with the control group,the frequencies of AA genotype ( 15.32％ vs.16.12％ ),AG genotype (53.47％ vs.51.86％ ),GG genotype (31.21％ vs.32.02％ ) and G allele genotype (57.95％ vs.57.95％ ) in ACS group were not significantly different ( P was 0.083,0.673,0.821 and 1.00,respectively).Multivariate logistic regression analysis indicated that there was no significant correlation between MCP-1 gene A-2518G polymorphism and ACS regardless of differences in gender,age,smoking,diabetes,TG and LDL-C ( P ＞0.05 ).There was no significant difference in gender and age of ACS onset between two groups ( P ＞ 0.05).There were no significant differences in the frequencies of AA,AG and GG genotypes and G allele genotype among AMI group,UAP group and normal coronary group ( P ＞ 0.05).Conclusions The data shows that MCP-1 gene A-2518G polymorphism is not associated with the risk of ACS in the Chinese Han ethnic population living in Sunan region.
ABSTRACT
Objective To investigate the expression and relationship of Jab1 and P27kip1 in ovarian cancer cell HO-8910. Methods Cells were treated with serum starvation and release.The expression and distribution of Jab1 and P27kip1 were detected by western blot and subcellular fractionation.HO-8910 cells were transfected in vitro with pcDNA3.1-MYC-Jab1.Western blot as well as subcellular fractionation was used to detect the expression and localization of P27kip1.Results The growth of HO-8910 cells was blocked by serum starvation.P27kip1 increased while Jab1 decreased.The reverse changes were found after serum release.P27kip1 and Jab1 could form compound in HO-8910 cells detected by immunoprecipitation.48h after transfected by pcDNA3.1-MYC-Jab1,the expression of P27kip1 decreased and the distribution of P27kip1 translocated from nucleus into cytoplasma in HO-8910.Conclusion Jab1 may control the location and expression of P27kip1 through integrating with P27kip1,and participate in regulating the growth of ovarian cancer cells through interfering with the function of P27kip1.
ABSTRACT
Objective To explore the clinical value of myomectomy and hysterectomy under laparoscope.Methods Fifty-eight cases of gynecological laparoscopic surgery were analyzed retrospectively,including 30 cases of myomectomy and 28 cases of classical intrafascial supracervical hysterectomy(CISH) or laparoscopic assisted vaginal hysterectomy(LAVH). Results The laparoscopic operation was successfully completed in all the 58 cases.The operation time was 89.4?12.1 min for myomectomy and 108.5?10.2 min for hysterectomy.On the second postoperative day,the decrease rate of hemoglobin was 11.3%?3.3% and 14.2%?3.2%.The length of hospital stay was 5.6?0.2 d and 6.6?0.5 d.Postoperative follow-up in the 58 cases for 3～17 months(mean,11.4 months) found 2 cases of complications(3.4%). Conclusions Laparoscopic myomectomy and hysterectomy offers little invasion and rapid recovery.
