Objective: To explore two-dimensional speckle tracking imaging (2D-STI) in evaluation on the changes of left atrial function in patients with paroxysmal atrial fibrillation before and after radiofrequency catheter ablation (RFCA). Methods: Echocardiography was performed on 30 patients with paroxysmal atrial fibrillation (AF group) treated by radiofrequency catheter ablation in the preoperation and postoperative 3 days, 1 month, 3 months. Thirty healthy volunteers were selected as the control group. The left atrial anteroposterior diameter (LAD), early diastolic transmitral flow velocity (E peak), mitral annular early diastolic motion velocity (Em), left atrial maximum, minimum and pre-systolic volume (LAVmax, LAVmin and LAVP) were measured and E/Em, left atrial active ejection fraction (LAAEF), left atrial passive ejection fraction (LAPEF) were calculated by conventional echocardiography. Left atrial strain and strain rate curves of each segment were obtained by 2D-STI, and the mean peak strain (mSs, mSe, mSa) and strain rate (mSRs, mSRe, mSRa) of the left atrial in the left ventricular systolic, the early diastolic stage and the late diastolic stage, and left atrial stiffness (LASt) was measured and calculated. The changes of the left atrial structure and function in patients with paroxysmal atrial fibrillation before and after RFCA were compared. Results: Compared with the control group, LAD, LAVp, LAVmin, LAVmax, E/Em and LASt increased in the AF group, LAPEF, LAAEF, E peak, Em, mSs, mSe, mSa, mSRs, mSRe and mSRa decreased (all P<0.05). There were statistically significant differences in left atrial strain parameters and LASt of patients with paroxysmal atrial fibrillation before and 3 days, 1 month and 3 months after RFCA (all P<0.05). Compared with the preoperative, mSs, mSe, mSa, mSRs, mSRe and mSRa decreased and LASt was increased at 3 days after RFCA (all P<0.05); mSs, mSe, mSa, mSRs, mSRe and mSRa increased, and LASt decreased at 3 months after RFCA (all P<0.05). Compared with the postoperative 3 days, mSs, mSe, mSa, mSRs, mSRe and mSRa increased, LASt decreased (all P<0.05) at 1 month and 3 months after RFCA. Compared with the postoperative 1 month, mSRs increased at 3 months after RFCA (P<0.05). Conclusion: The left atrium function of patients with paroxysmal atrial fibrillation decrease at 3 days after RFCA, the pump function improved 1 month after RFCA, and the left atrial reservoir, conduit and pump function improve observably at 3 months after RFCA.

Objective To evaluate the impact of HIV co-infection with HCV or HBV on the efficacy of highly active anti-retroviral therapy (HARRT). Methods The patients were divided into three groups: HIV + HBV + HCV co-infection group ( 23 patients), HIV + HCV co-infection group ( 166 patients), and HIV-only group (178 patients). HIV RNA, HCV RNA or HBV DNA were detected by real time PCR before treatment and 1,3,6,9 and 12 monthes after treatment, meanwhile the counts of CD4+ T lymphocyte and liver function including ALT, AST and TBil were tested. Results During one-year HAART, HIV RNA of HIV-only group, HIV + HBV + HCV co-infection group and HIV + HCV co-infection group decreased significantly from (6.78 ± 1.08), (6.23 ± 1.34), (6.54 ± 1.23) lg copies/ml to (0.53 ±0.15), (0.67 ±0.16),(0.43 ±0.11 ) lg copies/ml respectively (P＜.001 ). And CD4+ T lymphocyte counts of the three groups elevated significantly from ( 197 ± 127), (184 ± 113), (213 ± 143) cells/μl to (382 ±74), (383 ±70),(378 ±76) cells/μl respectively (P ＜0.001 ). However there were no differences among the three groups in HIV RNA and CD4+ T lymphocyte counts. There were no differences in liver functions including ALT,AST and TBil among the three groups. Conclusiom HIV co-infected with HBV and/or HCV does not impact on the efficacy of HAART. What more, HAART does not impact HCV replication.

Objective To investigate the expression of PD-1 on CD4 +and CD8 + T cells in patients with HBeAg-positive chronic hepatitis B(CHB)treated with telbivudine.Methods Fifty-six HBeAg-positive CHB patients admitted in the First Affiliated Hospital of Zhengzhou University during January 201 3 and June 201 4 were enrolled in this study.The expression of PD-1 on CD4 +and CD8 + T cells was detected with flow cytometry at baseline,24,48 and 72 wks after telbivudine treatment.The relationship of PD-1 expression with alanine aminotransferase (ALT)level,HBeAg seroconversion and HBV DNA loads was analyzed.t test and completely random variance analysis were used to analyze the data.Results The PD-1 expression on CD4 + and CD8 + T cells at baseline was higher in patients with low ALT levels compared to those with high ALT levels(t =1 2.20 and 9.69,both P <0.01 ),while higher levels of PD-1 expression was also observed in patients with high HBV DNA load (≥5 lgIU /mL)compared to those with low HBV DNA load (t =4.39 and 4.85,both P <0.01 ).PD-1 levels on CD4 + and CD8 + T cells presented a declining trend after telbivudine treatment(F =6.98 and 8.97,both P <0.01 ),PD-1 expression in patients with HBeAg seroconversion showed lower levels compared with baseline values (t =1 8.45 and 1 8.01 ,both P <0.01 ). Conclusion In HBeAg-positive CHB patients,the expression of PD-1 on CD4 + and CD8 + T lymphocytes shows a decreasing trend during the treatment with telbivudine,indicating that antiviral therapy may alleviate the immunosuppression in these patients.

OBJECTIVETo assess the association between aggressive behaviors and 15 short tandem repeats (STRs) loci.

METHODSPeripheral blood samples from 541 army men with aggressive behaviors and 459 healthy individuals were collected. All sample were amplified with a AmpFlSTR Identifiler(TM) system and separated by electrophoresis to compare the genotypic and allelic frequencies of 15 STRs (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, THO1, TPOX and vWA) in the two groups.

RESULTSA significant difference was found in allelic and genotypic frequencies at loci D2S1338 and D19S433 (P< 0.01) between the two groups, but not for the remaining 13 STR loci (P> 0.05). Univarite analysis also showed a significant difference for allele 16, genotypes 19-22, 22-24 on D2S1338 and genotypes 13-14.2 on D19S433 between the two groups (P= 0.0018, P= 0.0001, P= 0.0003, P= 0.0000), with the OR values being 7.380 (95%CI: 1.701-32.028), 0.051(95%CI: 0.007-0.388), 13.933(95%CI: 1.845-105.717), 0.349 (95%CI: 0.216-0.564), respectively.

CONCLUSIOND2S1338 and D19S433 may be associated with aggressive behavior. Allele 16 and genotype 22-24 on D2S1338 may be susceptible factors for the disease, whilst genotypes 19-22 on D2S1338 and 13-14.2 on D19S433 may confer a protective effect on it.
