Objective To estimate the characteristics of gastroesophageal reflux (GER) and its clinical association with pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc) patients.Methods Two hundred and five patients with SSc,who fulfilled the American College of Rheumatology criteria were consecutively recruited.GER was recognized in patients with symptom of heartburn or regurgitation.Demographic,clinical,and laboratory data were analyzed.A six minute walk test,pulmonary function test and modified Rodnan's skin score (mRSS) were also calculated for GER and non-GER groups.x2 test,Fisher's exact test and t-test were used for statistical analysis.Logistic regression test was used for the analysis of risk factors.Results There were 90 patients with GER among 205 patients,the prevalence of GER was 43.9％.The presence of PAH (23.3％ vs 9.6％),Raynaud's phenomenon (98.9％ vs 92.2％ ) and fingertip ulcers (56.7％vs 51.3％) were significantly higher in patients with GER than those without GER.There was no difference in autoantibody profile between GER patients and non-GER patients (P＞0.05).The New York Heart Association (NYHA) functional class of SSc-related GER was worse than patients without GER (P=0.015).Pulmonary function test showed that diffuse capacity (DLCO)％,forced vital capacity (FVC)％,and forced expiratory volume (FEV1)％ were lower and the FVC％/DLCO％ ratio was higher in patients with GER than non-GER (P＜0.05).GER was an independent risk factor of PAH in SSc patients (P=0.047,OR=3.41 ).Conclusion GER frequently occurs in SSc patients,SSc patients presenting with GER should be screened for PAH.Targeting the underlying vascular dysfunction might prevent not only PAH,but also GER in SSc patients.

Objective To investigate the levels, phenotypes and functions of regulatory T cells (Treg) and Th17 cells in systemic sclerosis (SSc) patients and assess the role of imbalance between Treg and Th17 cells in the pathogenesis of SSc. Methods Peripheral blood mononuclear cells (PBMCs) of 31 SSc patients and 33 healthy controls were analyzed for the expression of CD4, CD25, CD45RA, the cytotoxic T-lymphocyte antigen-4 (CTLA-4), FoxP3, and IL-17 using flow cytometry. Treg immunosuppression capacities were measured in co-cultured experiments. The expressions of IL-17A, IL-22, IL-6 and IL-1β were measured by FlowcytoMix. The expression of FoxP3, CTLA-4, IL-17A, and RORC mRNA were measured by real-time polymerase chain reaction (PCR). The independent samples t-test was used to compare data between the groups. Results The frequency of Treg cells was significantly elevated in SSc [(3.6 ±1.1)%] compared with controls [(2.0±0.8)%, t=6.88, P<0.01)] and the expression of CTLA-4 was lower in Treg cells of SSc (P=0.034). The expression of CTLA-4 and FoxP3 mRNA was lower in SSc compared with controls (P<0.05), the immunosuppressive capacity of Treg cells were diminished in SSc (P=0.034). Th17 cells were increased in SSc (P<0.01); the levels of IL-17A, IL-22, IL-6 and IL-1β in the serums of SSc were higher than the controls (P<0.05). In SSc, CD25+FoxP3+IL-17+cells were increased[0.075%±0.032)%vs (0.049±0.027)%, t=3.52, P=0.029], but no difference of CD25+FoxP3+IL-17- was observed when compared with control. The expression of IL-17A and RORC mRNA were increased in SSc (P<0.01, respectively). Conclusion Both Treg and Th17 cells are increased in patients of SSc. Treg increases along with the deficiency of phenotype and function. FoxP3+IL-17+co-express cells are increased, and the balance between Treg and Th17 cells is broken.

BACKGROUND:Arterial stiffness is an independent risk factor for cardiovascular disease.Augmentation index(Alx)is an important marker which reflects the systemic arterial stiffness.OBJECTIVE:To investigate Alx and the affecting factors in Xinjiang Uygur health adults.METHODS:A total of 559 healthy adults(251 males and 308 females)with a mean age of(44.95±11.87)years were selected from Hetian,Xinjiang Uygur Autonomous Region.The following indexes of all subjects were measured,including questionnaire,physical examination,blood biochemistry and C-reactive protein(CRP).Central systolic blood pressure(cSBP)and central Alx were measured by Sphygmocor.Pearson correlation and partial correlation analysis were used for two-group analysis of correlation,and multiple regression analysis was used to analyze influential factors for Alx.RESULTS AND CONCULUSION:Alx was greater in female than in male and was positively related to age in both sexes(male:r=0.548,female:r =0.405,P < 0.05),as well as adjusted other influential factors(male:r=0.182,female:r =0.234,P < 0.05).Multiple regression analysis showed that cSBP,systolic blood pressure(SBP),sex,age and CRP were main factors which affected Alx in Uygur healthy adults,cSBP,SBP,age,body mass and CRP were main factors which affected Alx in the male,while cSBP,SBP,age,height and CRP were main factors which affected Alx in the female.Results revealed that Alx was greater in female than in male which was positively related to age in both sexes.Age,cSBP,SBP and CRP were main factors that affected Alx in Xinjiang Uygur healthy adults.

The study was to observe the therapeutic effect of HJ-1 NO--HFJV respirator on treating pulmonary edema caused by seawater drowning. Seawater was infused into the rabbit's lung to establish the animal model of pulmonary edema caused by seawater drowning(PE-SWD). Then the animals were divided into three groups: simple PE-SWD model as control group, treat group(animal model treated with HFJV respirator and four medicines) and HFJV respiratior plus NO group. Pao2, Sao2 and pH were measured by the blood-gas analyzer. The survival time and seawater drowing-respiratiory distress syndrom(SW-RDS) were observed. The results showed that Pao2, Sao2 in NO group were remarkably higher than that of PE-SWD control group, and the survival time was longer than that of medicine treated group and the incidence of SW-RDS decreased to zero. We assume that HJ-1 NO-HFJV respirator is efficient on treating pulmonary edema.
