Results HBV specific CTL surface PD-1 expressions of group A were lower than that of group B (t = 11.101, P < 0.01), HBV specific CTL levels of group A were higher than that of group B (t = 24.424, P < 0.01), ALT of group A were lower than that of group B (t = 2.652, P < 0.01), ALB of group A were higher than that of group B (t = 2.347, P < 0.05). Child-pugh rating, grade C of group A was lower than that of group B (χ2= 4.262,P < 0.05). Conclusions HBV specific CTL surface PD-1 expression levels were higher in those hepatic cirrhosis patients with , high level of serum HBV DNA, and HBV specific CTL levels were lower, liver functions damage were much serious. So, lower HBV DNA levels , lower HBV specific CTL surface PD-1 expression levels and higher HBV specific CTL levels can product relatively good effect of anti-viral treatment.

Objective To investigate the impairment mechanism of learning and memory function induced by arsenite exposure through studying the effects of sodium arsenite on gliotransmitter release from astrocytes.Methods Primary cultured astrocytes were isolated from neonatal (0-3 days) Wistar rats and determined by glial fibrillary acidic protein (GFAP) immunofluorescence staining.The primary cultured astrocytes were randomly divided into four groups,in which astrocytes were exposed to 0.0,2.5,5.0,or 10.0 μmol/L sodium arsenite,respectively,for 24 h.Intracellular free Ca2+ concentration ([Ca2+]i) in astrocytes was measured by fluorescence dual wavelength spectrophotometer;,concentrations of glutamate,D-serine,glycine and γ-aminobutyric acid were measured by high performance liquid chromatography (HPLC).Results More than 95％ cells were positive for GFAP immunofluorescence staining.The difference of [Ca2+]i among groups treated with sodium arsenite was statistically significant (F =20.030,P ＜ 0.05).[Ca2+]i increased significantly in group treated with 10.0 μmol/L sodium arsenite [(263.27 ± 14.80)nmol/L] compared with those in groups treated with 0.0,2.5,5.0 μmol/L sodium arsenite [(204.24 ± 27.21),(214.49 ± 21.85),(232.74 ± 23.14)nmol/L,all P ＜ 0.05].The differences of the levels of D-serine,glycine and γ-aminobutyric acidamong groups treated with sodium arsenite were significant (F =26.599,33.539,5.599,all P ＜ 0.05).The levels of D-serine [(21.580 ± 1.313),(21.936 ± 1.539),(23.401 ± 1.648)μmol/L],glycine [(26.353 ± 2.449),(29.711 ± 1.530),(29.234 ± 2.057)μmol/L] and γ-aminobutyric acid [(27.277 ± 3.421),(30.213 ± 2.098),(29.364 ± 2.588)μmol/L] released by astrocytes increased significantly in groups treated with 2.5,5.0,10.0 μmol/L sodium arsenite compared with those in groups treated with 0.0 μmol/L sodium arsenite [(16.017 ± 1.046),(16.763 ± 3.007),(22.736 ± 4.139)μmol/L,all P ＜ 0.05].Conclusion Arsenite could affect gliotransmitter release from astrocytes,and further impair learning and memory function.

Objective To investigate the correlation between the mierosatellite polymorphism of heme oxygenase-1(HOX-1)gene promoter and susceptibility to chronic obstructive pulmonary disease(COPD)in Han nationality of Southwest China and CT imaging.Method The alleles frequencies with varying number of(GT)n repeatings in the Hox-1 gene in 180 smokers with COPD and in 150 healthy smokers were analyzed.Results Polymorphisms of the(GT)n repeats were grouped into three classes:S(≤25 repeats),M(26-31 repeats),L(≥32repeats).The proportion of genotypic frequencies in the group with class L alleles(L/S,L/M,I/L)was significantly higher in the smokers with COPD than in healthy smokers(29.4%vs18.7%,P=0.023,OR=1.8,95%CI 1.1-3.1).However,there was no relationship between the polymorphism of HOX-1 gene and subtypes of COPD by CT imaging in COPD patients(P＞0.05).Conclusion Genetic polymorphism in Hox-1 is associated with development of COPD in Han nationality of Southwest China.But the polymorphism of HOX-1 gene is not associated with subtypes of COPD by CT imaging.

Objective To study the correlation between pain, lower limb strength and physical function in patients with primary osteoporosis. Methods Fifty-seven female patients diagnosed with menopause-related low bone mass or primary osteoporosis using a GE calcaneus bone density detector were involved in this study. The muscle strength of their lower limbs was tested with a Biodex system 4 machine. Pain was assessed with a visual analogue scale, and physical function (PF) with the SF-36 instrument. Results Low back pain was significantly correlated with PF, and so was leg pain. Leg pain was also significantly correlated with the strength of the extensors of the dominant leg during low velocity and medium velocity movement. Leg pain was not, however, significantly correlated with the strength of the flexors of the dominant leg during low and medium velocity movement. Conclusions Pain predicts poor physical function in patients with primary osteoporosis or low bone density. During low and medium velocity movement, leg pain significantly predicts poor muscle strength in the extensors of the dominant lower leg, but it has no correlation with the muscle strength of the flexors.

Objective To investigate the relationship between the variation of endothelial progenitor cells (EPC) number and cardiovascular diseases (CVD) in maintenance hemodialysis (MHD) patients ,and discuss the function of EPC in the progression of CVD in MHD. Methods One hundred and fifteen MHD patients over 18 years whose dialysis vintage was over six months from Department of Nephrology, Renji Hospital, Shanghai Jiao Tong University School of Medicine were enrolled. They were divided into CVD group and non ? CVD group by medical history, electrokardiographie (EKG), cardiac ultrasound, peripheral vascular imaging and cardiovascular imaging. Peripheral blood (5 ml) was collected for detecting EPC number by flow cytometry as CD34/CD133/vascular endothelial growth factor receptor 2 (VEGFR2) cells. The EPC number between CVD group and non?CVD group was compared. The relationship between the decrease of EPC number and CVD risks in MHD patients was analyzed by logistic regression analysis. In a three?year follow?up, the death and new CVD events of the two groups were compared in order to discuss the relationship between EPC number and adverse events. Results Among 115 MHD patients, the average age was 61.57 ± 12.76, male/female was 71/44, the average dialysis vintage was (86.24 ± 56.31) months, the average Kt/V was 1.69 ± 0.29 and average ultrafiltration volume was (2.48 ± 0.90) L. Forty?four patients in 115 (38.3%) were with concurrent CVD. The EPC number in CVD group was significantly lower than that in non CVD group (P=0.015). The CVD group had higher serum phosphate (P=0.013), higher glycosylated hemoglobin (P<0.001), but serum calcium, intact parathyroid hormone (iPTH) and other indicators had no significant difference between two groups. Multiple Logistic regression analysis showed that older age (OR=1.061), history of diabetes (OR=9.796), dialysis vintage (OR=1.015), serum phosphate (OR=3.766), decrease of EPC number (OR=0.909) were the independent impact factors of CVD events in MHD patients. There were 22 patients of the 115 MHD patients had encountered a new CVD event in a three?year follow?up between December 2012 and December 2015, 9 patients from the CVD group and 13 patients from the Non?CVD group, and there was no significant difference between two groups (P=0.776). Nine patients from the CVD group and 7 patients from the Non?CVD group died in the follow?up, and there was no significant difference (P=0.111). Seventy?one MHD patients from the non?CVD group were divided into two groups by the median of EPC number. There were 3 patients in the higher EPC number group encountered CVD events and 10 patients in the lower EPC number group encountered CVD events, which had significant difference (P=0.024). Conclusion The decrease of circulating EPC number may be related with CVD events in MHD patients. Even adjusted by age, sex, diabetes, dialysis vintage and serum phosphate, decreased EPC number is still the independent risk factor of CVD events in MHD patients. The decrease of EPC number in MHD patients may be used to predict the occurrence of cardiovascular events.

Background:The pathogenesis of irritable bowel syndrome(IBS)is not fully known,social psychological factor is the important factor of IBS,especially the relationship with anxiety and depression. Aims:To investigate psychological stress factor,anxiety and depression in IBS patients among soldiers in northeast area. Methods:A total of 11 400 soldiers in northeast area were enrolled by multistage,stratified,cluster random sampling method asking to fulfill a questionnaire on IBS. Zung self-rating anxiety scale(SAS)and Zung self-rating depression scale(SDS)were assessed,and the relationship with anxiety,depression and stress was analyzed. Results:The incidence of IBS was 15. 9% . Prevalences of anxiety and depression in IBS group were significantly higher than those in non-IBS group(22. 9% vs. 9. 6% ,26. 6% vs. 12. 4% ,P< 0. 05). Score of SAS and SDS in IBS group were significantly higher than those in non-IBS group(50. 86 ± 7. 27 vs. 36. 54 ± 6. 97,53. 47 ± 7. 86 vs. 38. 25 ± 9. 83,P < 0. 05). Positive correlation was found between score of SAS and SDS and stress factors such as feeling lonely,depression,intensive training,working pressure,poor relationship with colleagues,solving emergency event or participating in military exercises in IBS group(P < 0. 05). Conclusions:IBS in soldiers is related with stress and psychological factors.
