Background Age-related cataract is one of the common causes of blindness.Although the pathophysiology of age-related cataract is far from clearly understood,it is well accepted that DNA damage plays an important role in the disease pathogenesis.Objective The purpose of this study was to quantitatively evaluate the DNA damage in peripheral lymphocytes of age-related cataract.Methods A cross-sectional study was carried out.This study complied Declaration of Helsinki and approved by Ethic Committee of Affiliated Hospital of Nantong University.Written informed consent was obtained from each subject.Two hundred and eleven patients with agerelated cataract and 147 normal subjects were enrolled from a “ Jiangsu Eye Study:Funing 2011 Eye Disease Epidemic Survey”.All the subjects aged from 50 through 80 years with matched age and gender between the two groups.The percentage of tail DNA and Olive tail moment (OTM) were detected by comet assay to assess the extent of DNA damage in peripheral lymphocytes.Statistical analyses were performed with SPSS 17.0 software,and the differences of the percentage of tail DNA and OTM were compared between the age-related cataract group and normal control group by independent sample t test as well as among the 50-59 years group,60-69 years group and ≥70 years group by one-way analysis of variance.Results Comet assay showed a round lymph cell with the clear border in the normal group;while in the age-related cataract group,the cell was bigger with a comet-like tail.The percentage of tail DNA and OTM in peripheral lymphocytes were (21.75 ± 3.51) ％ and 6.54 ± 1.65 in the age-related cataract group,and those in the normal control group were (9.31 ±3.60)％ and 2.18 ± 1.10,respectively,with significant differences between them (t =32.67,P =0.00 ; t =28.02,P =O.00).In the 50-59 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.04±2.86) ％ and 5.92± 1.14,and in the 60-69 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.77 ±2.93) ％ and 6.13 ± 1.14,which were significantly reduced in comparison with (22.79 ± 3.67)％ and 6.95±1.91 of the ≥70years subgroup(TailDNA％:q=2.75,P=0.00; q=2.02,P=0.00;OTM:q=1.03,P =0.02 ; q =0.82,P =0.00).Conclusions The pathogenesis and development of age-related cataract probably is associated with DNA damage.

Maintaining genetic diversity is a major issue in conservation biology. In this study, we demonstrate the differences of genetic diversity levels between wild and captive individuals of Elliot's Pheasant Syrmaticus ellioti. Wild individuals showed a higher genetic diversity level than that of the captive individuals. Nucleotide diversity and haplotype diversity of wild individuals were 0.00628 and 0.993, while those of captive individuals were 0.00150 and 0.584 respectively. Only 3 haplotypes of mtDNA control region sequence were identified among 36 captive individuals, while 16 unique haplotypes were identified among the 17wild individuals in this study. One captive haplotype was shared by a wild individual from Anhui Province. It is concluded that a low number of founders was the likely reason for the lower level genetic diversity of the captive group. Careful genetic management is suggested for captive populations, particularly of such an endangered species, to maintain genetic variability levels.

Objective The aim of this trial is to compare the efficacy and safety between national-made and imported ablation catheters for the treatment of atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT). Method A total of 1342 patients with AVNRV or AVRT were randomly treated with national-mode ablation catheter (Group 1, n = 672) or imported ablation catheter (Group 2, n=670). Results The immediate ablation success rate was similar in Group 1 and Group 2 (97.9% vs. 99.1%, P > 0.05). There were also no significant differences in the procedure time [(68±36) min vs. (67±34 ) min], the fluoroscopic time [(14±14) min vs. (10±11) min], the number of energy delivery [(4.5±4.5) beats vs. (4.6±3.9) beats], the ablation time [(260±218) s vs. (257±207) s] and the score of ablation catheter performance evaluation[(4.4±0.5) vs. (4.5±0.4)] between the two groups (all P > 0.05). Three patients developed pericardial effusion (1 in Croup 1 and 2 in Group 2, P>0.05). Incidence of recurrence of tachycardia during the 3 months follow up was similar between the 2 groups (14 in Group1 vs. 16 in Group 2, P > 0.05). Conclusion National-made and imported radiofrequency ablation catheters have similar efficacy and safety for treatment of AVNRT and AVRT.

AIM:To study the value of copeptin(CPP)level for the prediction of cardiorenal syndrome (CRS)in the rats with subtotal nephrectomy(SNX)combined with myocardial infarction(MI).METHODS: Male SD rats(n=60)were divided into blank control group(Con group), renal failure group(SNX group), heart failure group (MI group)and heart failure+renal failure group(CRS group).The concentrations of CPP in the serum and urine,hemo-dynamic indexes,blood pressure and renal function indexes were measured 1~5 weeks after modeling.The predictive val-ue of CPP for CRS in the rats was evaluated by the receiver operating characteristic(ROC)curve.RESULTS:Compared with Con group,left ventricular systolic pressure(LVSP)at 9 d in CRS group was significantly decreased(P<0.05),left ventricular end-diastolic pressure(LVEDP)at 9 d in CRS group was significantly increased(P<0.05), and the differ-ence of blood pressure at each time point was not statistically significant.The levels of blood urea nitrogen(BUN)and uri-nary creatinine(Ucr)in CRS group were significantly increased at 1 and 3 weeks(P<0.05).Compared with Con group, serum CPP level was significantly increased at 1,3 and 5 weeks(P<0.05), and urine CPP level was significantly in-creased at 3 weeks in CRS group.Serum brain natriuretic peptide(BNP)level was significantly increased at 1 and 3 weeks,while urine BNP level was significantly increased at 5 weeks after modeling in CRS group(P<0.05).No correla-tion between serum or urine CPP and BNP or BUN levels at 1 week in CRS group was observed.The results of ROC curve analysis indicated that the area under the curve(AUC)of serum CPP was 0.908(95%CI:0.789~1.028),and the cut-off value was 56.59 ng/L(sensitivity 0.875,specificity 0.800).CONCLUSION:The combination of SNX and MI estab-lishes a CRS rat model with both heart and kidney injury,and serum CPP can be used as a sensitive and specific biomarker for early prediction of CRS.

PURPOSE: Gastric cancer often occurs in the elderly but is uncommon in young individuals. Whether young patients have different clinical behaviors and outcomes from those of older patients remain unclear. MATERIALS AND METHODS: We identified 1,366 cases of newly diagnosed noncardia gastric adenocarcinoma from the Kaiser Permanente Northern California Cancer Registry between 2000 and 2010. We then compared the clinicopathological features and survival among the different age groups. RESULTS: The male : female ratio differed significantly between the younger and older patient groups (0.84 in age <50 years vs. 1.52>60 years, P<0.01). More younger patients were Hispanic (54% patients <40 years vs. 19% patients > or =70 years, P<0.0001), while more older patients were Caucasian (49% patients > or =70 years vs. 15% patients <40 years; P<0.0001). The diffuse/mixed histological type was more prevalent in younger patients (70% patients <40 years vs. 27% patients > or =70 years; P<0.0001), whereas the intestinal type was more frequent in older patients (71% in patients > or =70 years vs. 30% in patients <40 years; P<0.0001). Poorly differentiated adenocarcinoma was more common in the younger patients (80% in patients <40 years vs. 60% in patients > or =70 years; P=0.016). Survival rates at 1, 2, and 5 years gradually declined with increasing age (overall P=0.0002). CONCLUSIONS: Young patients with gastric cancer had more aggressive disease but higher overall survival rates than older patients. Younger Hispanic patients and older Caucasian patients were more likely to be diagnosed with gastric cancer. These differences may be due to biological predisposition and/or environmental exposure.
