Objective To explore quality of life and coping style of autistic children' s parents, and correlation between them. Methods 68 parents of children with autism and 64 healthy children' s parents were tested with comprehensive assessment questionnaire of the quality of life and coping style questionnaire. Data were analyzed by t -test and multivariate regression analysis. Results The scores of material life and mental health dimensions in study group(48.18 ± 12.80,60.63 ± 10.18 ) were lower than that in control group(52.71±9.84,65.79±8.64) and the difference was significant( t= -2.04, P＜0.05; t= -3.09, P＜0.01 ). The scores of "problem solving" coping style in study group were slower than in control group; the scores of fantasy and wincing coping style in study group were higher than that in control group. By multivariate regression analysis showed that the scores of "problem solving" coping style were positively correlated with total score of life quality,physical health,mental health and social function dimensions; the scores of "fantasy" coping style had negative correlation with the total score of life quality; the scores of "wincing" coping style had negative correlation with mental health dimension. Conclusion Parents of autistic children were more susceptible to problems of physical life and mental health. Compared to parents of normal children they are more in "fantasy and wineing style and less in" problem solving style to cope with stress, so it would affect the quality of life and mental health badly and need early intervention.

Objective: To analyze the prevalence and predictor for left ventricular reverse remodeling (LVRR) in patients of primary hypertension combining left ventricular systolic dysfunction (LVSD) with tailored medication.
Methods: A total of 118 consecutive patients admitted in our unit from 2010-08 to 2012-10 with the base line left ventricular ejection fraction (LVEF)≤40%were enrolled. The demographic and clinical information with the findings of echocardiography at admission were collected. The patients were followed-up until 2013-12 or until the all cause death/cardiac transplantation. According to echocardiography, LVRR was deifned by 2 criteria at the same time:①the absolute elevation of
LVEF≥10%than base line and the follow-up LVEF≥50%,②the relative reduction of left ventricular end-diastolic diameter (LVEDD) index≥10%than base line and the follow-up LVEDD index≤27 mm/m2. LVRR prevalence with its base line predictor was investigated.
Results: The overall mean follow-up time was (23 ± 15) months, and 39/118 (33.1%) patients acquired LVRR as LVEF from the base line level (30.6 ± 6.8)%increased to the follow-up level (57.0 ± 4.9)%;LVEDD index from the base line level (31.6 ± 3.9) mm/m2 decreased to the follow-up level (24.4 ± 1.9) mm/m2, all P<0.01. The average time length for reaching LVRR was (11 ± 9) months, and 27/39 (69.2%) patients reached LVRR within 12 months. There were 79 patients not reached to LVRR, while their LVEF also from the base line level (28.6 ± 6.1)%increased to the follow-up level (39.0 ± 13.2)%;LVEDD index from the base line level (38.1 ± 5.6) mm/m2 decreased to the follow-up level (36.1 ± 6.9) mm/m2. Multivariable logistic regression analysis indicated that the patients with the shorter duration of heart failure (HF) as>6 months vs≤6 months (OR=0.244, P<0.01), shorter QRS interval as≥120ms vs<120ms (OR=0.276, P<0.05) and the higher quartile of systolic blood pressure (SBP)/LVEDD index (OR=2.724, P<0.01) at admission were the independent predictors for LVRR.
Conclusion:With tailored medication, about 1/3 of patients with hypertension combining LVSD could acquire LVRR, the patients with shorter duration of HF, shorter QRS interval and higher ratio of SBP/LVEDD index had more possibilities.

Objective: To investigate the prevalence of hyponatremia and the relationship between hyponatremia and prognosis of dilated cardiomyopathy (DCM) for in-hospital patients. Methods: A total of 515 consecutive in-hospital DCM patients treated in HF center of Fu Wai Hospifal from 2008-10 to 2013-10 were retrospectively studied. Hyponatremia was deifned as the serum level of sodium < 135 mmol/L at ifrst admission. The prevalence of hyponatremia and the relationship between hyponatremia and DCM prognosis were studied including the risk of in-hospital time and mortality, the rates of all cause death and HF worsening death after discharge. Surviving patients were followed-up by clinical or telephone visit until 2014-11 or until the death. Results: There were 134/515 (26.0%) patients suffered from hyponatremia at admission, the serum level of sodium was related to HF symptom duration, NYHA functional classiifcation, systolic blood pressure (SBP), left atrial diameter and total bilirubin level, allP<0.01. Compared with non-hyponatremia, the patients with hyponatremia presented longer in-hospital time(14.8±11.1) days vs (11.2±5.8) days and higher in-hospital mortality (18.7% vs 1.8%), bothP< 0.01. There were 483 survivors discharged and were followed-up for (30.7 ± 19.5) months, during that period, the rates of all cause death and HF worsening death were 26.5% and 21.9% respectively. The patients with hyponatremia had the higher rates of all cause death (47.7% vs 20.3%) and HF worsening death (44.0% vs 15.5%), bothP<0.01. Multiple Cox regression analysis showed that with adjusted HF history (> 6 months vs≤ months ), NYHA functional classiifcation (Ⅱ-Ⅳ), SBP (per 10 mmHg elevation), total bilirubin level (per 1 mg/dl change) and LVEDD (per 5 mm change), the hyponatremia at admission is still one of the important independent predictors for all cause death (HR=1.836, 95% CI (1.248-2.702),P<0.01 and HF worsening death HR=2.139, 95% CI (1.406-3.253),P<0.01 in DCM patients after discharge. Conclusion: Hyponatremia is a common electrolyte disorder for in-hospital DCM patients, it is related to longer in-hospital time and higher mortality; higher rates of all cause death and HF worsening death after discharge in DCM patients.

Objective To evaluate the diagnostic value of expression of MG7-Ag diflferentiation and guidance of follow-up mucosal biopsy in the patients with suspected malignanct gastric ulcer.Methods The expression of MG7-Ag in 58 patients who were suspected as having malignant gastric ulcer under routine endoscopy was studied by immuno-histochemical staining.The follow-up endoscopy was pefformed 1 to 72 weeks(mean 7 weeks)later and biopsy was taken.Results There were 19 cases of gastric carcinoma in 30 patients with positive MG7-Ag expression(63.3%)and only 5 in 28 patients with negative MG7-Ag expression(P＜0.01).Conclusion The positive expression of MG7-Ag is correlated with gastrie carcinoma in patients with suspected malignant gastric ulcer.

OBJECTIVE: To observe the status of protein kinase B(Akt) signaling pathway in Akt phosphorylation induced by free silica(SiO_2) in mouse monocyte macrophage cell RAW264.7, and the role of Akt signaling pathway in early inflammatory response of silicosis. METHODS: i) RAW264.7 cells were routinely cultured and divided into SiO_2 stimulation groups at 5 different time points, and were stimulated for 15, 30, 60, 120 and 240 minutes with SiO_2 suspension with a final concentration of 100 mg/L, and a control group without SiO_2 treatment. At the end of treatment, the cells were collected and the expression of phospho-(Ser/Thr) Akt(p-Akt) was detected by Western blotting to select the optimal time of treatment. ii) RAW264.7 cells were divided into control group(no treatment), SiO_2 exposure group(previous concentration of 100 mg/L SiO_2 suspension) and intervention group(pre-treated with Akt activation inhibitor deguelin for one hour and then treated with 100 mg/L SiO_2 suspension), samples were collected after incubation for 60 minutes. The p-Akt expression and distribution in cells were detected by cellular immunofluorescence assay, the relative expression of p-Akt in cells was detected by Western blotting, and the levels of tumor necrosis factor-α(TNF-α) and transforming growth factor-β1(TGF-β1) in the supernatant of cells were detected by enzyme-linked immunosorbent assay. RESULTS: i) The optimal treatment time of RAW264.7 cells for SiO_2 exposure model was 60 minutes in vitro. ii) The results of cellular immunofluorescence assay showed that Akt phosphorylation was activated in RAW264.7 cells after stimulant with SiO_2, and the fluorescence of p-Akt was enhanced in the SiO_2 exposure group than the control group, and in the intervention group it was relatively weaker than the SiO_2 exposure group. The relative expression of p-Akt as well as the levels of TNF-α and TGF-β1 in the SiO_2 exposure group and the intervention group were higher than that in the control group(P<0.05), and the above three idexes in the intervention group were lower than the SiO_2 exposure group(P<0.05). CONCLUSION: Akt signaling pathway is involved in the process of SiO_2-induced macrophages phosphorylation, and participates in the early inflammatory response of silicosis.

Objective To observe the frequency and explore the predictors of left ventricular reverse remodeling(LVRR) in patients with recent onset dilated cardiomyopathy (RODCM) on tailored medical therapy.Methods Patients hospitalized with RODCM in Heart Failure Care Unit in Fuwai Hospital from October 2008 to December 2013 were reviewed and followed up to December 2014 or death or cardiac transplantation.Patients were treated with tailored medical therapy.LVRR was defined as an at least 10％ increase in left ventricular ejection fraction(LVEF) and to a final level of ≥ 50％ and an at least 10 mm decrease in left ventricular end-diastolic diameter (LVEDD) and to a final level of ≤ 55 mm on repeat echocardiogram.Clinical,electrocardiogram and echocardiographic variables at baseline were evaluated to identify predictors of LVRR by multivariable logistic regression analysis.Results A total of 137 patients with RODCM were enrolled in this analysis.During a median follow-up period of 25 months (range 6 to 64 months) with repeat echocardiography,46 patients(33.6％) were defined as LVRR,LVEF increased from (30.8±5.9) ％ at baseline to(59.7 ±4.6) ％ on follow-up(P＜0.01) and LVEDD decreased from (63.8 ±4.0) mm at baseline to (49.6 ±3.5) mm on follow-up(P ＜0.01) in these patients.Multivariable logistic regression analysis showed that higher systolic blood pressure at presentation (per 10 mmHg (1 mm Hg =0.133 kPa) increase,OR =1.379,P ＜ 0.01),shorter QRS interval (≤ 100 ms vs.＞ 100 ms,OR =2.959,P ＜ 0.01) and smaller LVEDD (per 5 mm increase,OR =0.684,P ＜ 0.01) at baseline were independent predictors of LVRR.Conclusins On current tailored medical therapy,LVRR could be achieved in about one third of patients with RODCM.Patients with higher systolic blood pressure on admission,shorter QRS interval and smaller LVEDD at baseline are associated with a higher likelihood of occurrence of LVRR.

Objective To observe the frequency and predictors of recovery of normal left ventricular ejection fraction (LVEF) and end-diastolic diameter (LVEDD) in patients with dilated cardiomyopathy (DCM).Methods A consecutive cohort of 296 patients with DCM were reviewed and followed up for at least 12 months or to death or cardiac transplantation,to identify those with recovery of normal LVEF,defined as LVEF ≥ 50％,or recovery of normal LVEDD,defined as LVEDD ≤ 55/50 mm for male/female,or both by follow up echocardiography.Variables regarded as potentially relevant to left ventricular function and dimension recovery were evaluated to identify predictors using multivariable logistic regression analysis.Results After a median follow-up of 28 months,normal LVEF was evidenced in 81 patients (27.4％),normal LVEDD was found in 63 patients (21.3％) and both parameters were recovered in 52 patients (17.6％),LVEF was increased from (31.7 ±6.3)％ to (57.5 ±5.2)％ (P ＜0.01) and LVEDD decreased from (62.7 ± 4.3) mm to (50.2 ± 3.7) mm (P ＜ 0.01) in these 52 patients.Multivariable logistic regression analysis showed that shorter symptom duration,higher systolic blood pressure at admission,smaller LVEDD and lower LVEF by echocardiography at baseline were independent predictors of subsequent recovery of normal LVEF and LVEDD.Conclusion Current therapy for heart failure could lead to recovery of normal LVEF and LVEDD in part of DCM patients,especially for DCM patients with short symptom duration,higher systolic blood pressure at admission,less enlarged LVEDD and less reduced LVEF at baseline echocardiography.

Objective To investigate the prevalence and prognostic value of hyponatremia on admission in hospitalized patients for heart failure (HF) from the first HF management center in China.Methods Consecutive adult (age of 18 years or older) symptomatic HF patients (NYHA functional class Ⅱ-Ⅳ) admitted between March 2009 and March 2012 in our center were included in the present analysis.Hyponatremia was defined as a serum sodium level ＜ 135 mmol/L.Association between hyponatremia on admission and in-hospital mortality as well as all-cause death and heart failure death during 1-year follow-up after discharge was analyzed.Results A total of 1 048 hospitalized patients for HF with complete baseline data were enrolled and the prevalence of hyponatremia on admission was 9.2％ (96/1 048).Blood pressure was significantly lower while NYHA functional class and N-terminal pro-B type natriuretic peptide levels were significantly higher in hyponatremic patients than non-hyponatremic patients (all P ＜ 0.05).Kaplan-Meier survival analysis showed that patients with hyponatremia on admission had significant higher in-hospital mortality (P ＜ 0.01), all-cause death rate (P ＜ 0.01) and HF death rate (P ＜ 0.01) during 1-year follow-up post discharge compared with non-hyponatremic patients with.Multiple Cox proportional hazard analysis showed that hyponatremia on admission remained as independent predictor for all-cause death (hazard risk (HR) =2.105, 95％ confidence interval (CI) 1.460-3.036, P ＜ 0.01) and HF death (HR =2.458, 95％CI: 1.704-3.545, P ＜0.01) after adjustment for other covariates.Conclusion Hyponatremia is relatively common in patients hospitalized with HF in China and hyponatremia on admission is associated with higher in-hospital mortality and all-cause death and HF death one year after discharge.

Objective To investigate the frequency and predictors of recovery and relapse of left ventricular systolic dysfunction (LVSD) in hospitalized patients with dilated cardiomyopathy (DCM).Methods Patients with DCM hospitalized in Fuwai Hospital from October 2008 to December 2013 with repeat echocardiography results after discharge were reviewed and followed to December 2014 or until all-cause death or cardiac transplantation.Rate of recovery of LVSD,defined as an absolute increase in left ventricular ejection fraction (LVEF) of ＞ 10％ to a level of ＞50％ on follow-up,and those with relapse of LVSD,defined as a decrease in LVEF to a level of ＜ 45％ after initial recovery was obtained and related factors affecting LVSD recovery and relapse were analyzed.Results After a mean follow-up of (28 ± 17) months,recovery of LVSD was evidenced in 114 of 382 patients (29.8％),LVEF increased from (31.6 ± 6.0) ％ to (55.8 ±3.7) ％ (P ＜0.01) and left ventricular end-diastolic diameter (LVEDD) decreased from (65.1 ± 6.7) mm to (53.5 ± 4.9) mm (P ＜ 0.01) in these patients.Multiple logistic regression analysis showed that symptom duration of heart failure (OR =0.986,P ＜ 0.01),systolic blood pressure (SBP) (OR =1.026,P ＜0.01),LVEDD (OR =0.938,P ＜0.01) andLVEF (OR =1.038,P ＜0.05) at admission were independent predictors of LVSD recovery.During the subsequent follow-up of (24 ± 13) months after initial recovery,17 of 88 patients (19.3％) suffered a relapse of LVSD,LVEF decreased from (54.3±2.6) ％ to (36.6±5.1) ％ (P＜0.01),LVEDD increased from (57.5±4.2) mmto (62.8± 6.8) mm (P ＜0.01) in these patients.Multiple logistic regression analysis showed that less decrease in LVEDD at initial recovery of LVSD was independent predictor of LVSD relapse.Conclusions About 30％ hospitalized patients with DCM experienced LVSD recovery in this patient cohort.Symptom duration of heart failure,SBP,LVEDD and LVEF on admission were predictors of LVSD recover.Moreover,LVSD relapse was observed in around 20％ patients after initial LVSD recovery and less decrease in LVEDD at initial recovery serves as an independent risk factor for LVSD relapse.

Objective:To study the patterns of tocilizumab (TCZ) use, its efficacy and safety in patients with rheumatoid arthritis (RA) in routine clinical practice.Methods:A total of 407 patients with RA were enrolled from 23 centers and treated with TCZ within 8 weeks prior to the enrollment visit, and were followed for 6-month. The patterns of TCZ treatment at 6 months, the effectiveness and safety outcomes were recorded. Statistical analysis was performed using SAS version 9.4.Results:A total of 396 patients were included for analysis, in which 330 (83.3%) patients received TCZ combined with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and 16.7%(66/396) received TCZ monotherapy. At baseline, TCZ was initiated in 56.6%(224/396) and 9.6%(38/396) of patients after failure of DMARDs and other biological agents (bDMARDs) respectively. During the 6-month follow-up period, the mean frequency of TCZ administration was (3.7±1.6), the mean TCZ dosage was (7.4±1.2) mg/kg, and the mean interval between doses was (40±13) days. 120(25.8%) patients were on TCZ treatment at the end of the study. Improvements in disease activity, systemic symptoms and patient report outcomes were observed at the end of the study. 22.7%(90/396) patients experienced at least one treatment related adverse event, and 8 patients experienced at least one serious adverse event.Conclusion:This study demonstrates that TCZ treatment is effective in patients with RA when being treated for 6 months with an acceptable safety profile. The duration of TCZ treatment needs to be extended.
