Objective To determine the age-specific normal ranges of serum prostate-specific antigen (PSA) levels in Dalian,China.Methods Serum samples were collected from 8 453 asymptomatic men who underwent health examinations at the Second Affiliated Hospital of Dalian Medical University.Results The median PSA level was 0.93 μg/L,and the interquartile level was 0.81 μg/L.The 95th percentile level was 3.49 μg/L.The 95th percentile levels according to age group were:20 to ＜30 years,0 to 1.67 μg/L;30 to ＜40 years,0 to 2.01 μg/L;40 to ＜50 years,0 to 2.41 μg/L;50 to ＜60 years,0 to 3.25 μg/L;60 to ＜70 years,0 to 3.92 μg/L;70 to ＜80 years,0 to 5.48 μg/L;and older than 80 years,0 to 9.35 μg/L.The differences between the different age groups were statistically significant (P ＜ 0.01).The serum PSA value was positively correlated with age (r =0.251,P ＜ 0.001).Conclusion There were clear differences in age-specific PSA levels in Dalian,and these were lower than the standard OESTERLING.Screening for prostate cancer according to age-specific PSA reference values may be useful in the early detection of prostate cancer and may also reduce the risk of over-diagnosis.

Objective To evaluate the efficacy of laparoscopic Habib 4X (Habib 4X,Angio Dynamics US),a new bipolar radiofrequency (RF) device,in laparoscopic liver resection.Methods Thirty one patients who underwent laparoscopic liver resection using the laparoscopic Habib 4X from Sept 2009 to Apr 2012 were studied retrospectively.Results The laparoscopic Habib 4X was success fully used in 30 patients (malignant,n=18; benign,n=12).The procedures performed included left lateral sectionectomy (n=12),left hemi-hepatectomy (n=1),Ⅴ or Ⅵ segmentectomy (n=9),Ⅴ and Ⅵ bi-segmentectomy (n=2) and wedge exclusion (n=6).The time required for precoagulation and resection was 10～68 min (median 24 min).The mean intraoperative blood loss was 145±75ml (range 8-370 ml).Mild abnormal liver function which returned to normal in 3 to 5 days was detected postoperatively.The mean hospital stay was 7.8±2.6 d (range 3～12 days).There was no patient who developed postoperative bleeding,bile leakage or abdominal abscess.For cancer patients,there was no local recurrence on follow-up.Conclusion Laparoscopic Habib 4X,a device when used in laparoscopic liver resection,resulted in minimal blood loss and quick recovery.It had only mild effect on liver function and it had low morbidity.In addition,it might reduce the risk of local recurrence in malignant tumours.

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.

Objective To assess the efficacy of Ezscan in evaluating the risk of cardiac autonomic neuropathy (CAN) in diabetes. Methods This study included 144 patients with diabetes. Their serum lipid profile and HbA1c were determined. The heart rate variability was assessed by Holter, and the cardiac autonomic neuropathy by classic experiments. Meanwhile, Ezscan was carried out. Results There was a positive correlation between low frequency (LF) measurements by Holter and Ezscan score( r=0. 39, P＜0. 01 ), so did LF/HF and Ezscan score( r=0. 28, P＜0. 01 ). Correlations between Ezscan score and other Holter parameters were weaker. There was no correlation between HbA1c and LF measurements. In patients with positive classic experiments, the sensitivity and specificity of Ezscan were 58. 3% and 57.8% respectively. Conclusions Ezscan test is a valuable screening procedure for detecting diabetic complications. It is more facilitative and takes shorter time than does the classical autonomic function assessment.
