Objective To investigate the changes of high mobility group box-1 ( HMGB1 ) and VE-cadherin in serum of children with viral myocarditis and their clinical significance. Methods The serum levels of HMGB1 and VE-cadherin were detected by ELISA in 52 children with viral myocarditis, and 36 normal healthy children were enrolled as control. CK-MB was also measured in all subjects enrolled into the study. Results The serum levels of HMGB1, VE-cadherin and CK-MB in children with acute stage viral myocarditis (HMGB1 :[5.14 ±0. 23] mg/L;VE-cadherin: [5.36 ±0. 92] mg/L;CK-MB: [31.42 ± 3.22] U/L)were significantly higher than those with recovery stage viral myocarditis ( HMGB1: [ 0. 92 ± 0. 14 ] mg/L, VE-cadherin: [2. 93 ±0. 64] mg/L; CK-MB: [ 13.75 ± 3.18 ] U/L) ( t = 11.37,10. 26 and 12. 17 respectively ,Ps ＜ 0. 01 )and control (HMGB1 :[ 0. 86 ± 0. 12 ] mg/L; VE-cadherin: [ 2. 86 ± 0. 65 ] mg/L; CK-MB: [ 12. 83 ±3.04] U/L) (t = 12.06,11.19 and 12. 64 respectively,Ps ＜0.01 ). However,we found no significant difference in the serum levels of HMGB1, VE-cadherin and CK-MB between recovery stage viral myocarditis group and the control ( t = 1.26,1.19,1.43, Ps ＞ 0. 05 ). There were positive correlations between HMGB1 and VE-cadherin,CK-MB (r = 0. 73,0. 79, Ps ＜ 0. 05 ) ;and positive correlation between VE-cadherin and CK-MB (r= 0. 82, P ＜0.05). Conclusion HMGB1 and VE-cadherin may play roles in the viral myocarditis pathogenesis, which can be new prognosis factors for viral myocarditis.

Objective To investigate the prognostic value of heart rate turbulence (HRT) in patients with chronic heart failure (CHF). Methods From October 2006 to May 2009, a total of 96 elderly CHF inpatients were selected, and the clinic data were recorded. Based on the echocardiogram and dynamic electrocardiogram, the differences of sinus HRT index of patients with different cardiac function classification were analyzed. During 9-28 months medical follow-up, the treatment endpoint was death from heart disease. Based on Logisitc regression, the prognostic values of HRT, age, hypertension, diabetes, myocardial infarction (MI), left ventricular ejection fraction, ACEI and β- adrenergic blocker for death of CHF patients were analyzed.Results There was no significant difference in HRT between grade Ⅱ and grade Ⅲ cardiac function (χ~2 = 1.60, P>0. 05), and between grade Ⅲ and grade Ⅳ cardiac function (χ~2 = 1.43, P>0. 05). But there was significant difference in HRT between grade Ⅱ and grade Ⅳ cardiac function patients χ~2 =9.84, P<0. 05), and HRT was weaken in grade Ⅳ group. The average follow-up time was (18. 0±9.6) months. Of all 96 patients, there were 34 dead of heart disease. There were correlations of death of CHF with HRT, low LVEF (≤ 45%), age (≥65 years), diabetes, MI and classification of heart function. Conclusions The sinus HRT in CHF patients has a favorable prognostic value.

Objective To explore the mucosal healing quality of hydrotalcite combined with esomeprazole in gastric ulcer.Methods Forty-two patients visiting from June 2014 to December 2015 and diagnosed with gastric ulcer were selected and divided into combination therapy group and single therapy group with 21 patients in each group.The patients of combination therapy group received esomeprazole combined with hydrotalcite,and the patients of single therapy group received esomeprazole alone.The total therapeutic course was eight weeks.At the same period,21 health check-up participants were enrolled as normal control group.The healing of gastric ulcer was observed under white light endoscopy.The morphological changes of gastric pits and microvessel of mucosal at peripheral mucosa around ulcer and normal gastric mucosal were observed under narrow band imaging magnifying endoscopy.The gastric mucosa tissues of the two groups before and after treatment,and normal gastric mucosa of healthy control group were taken.The amount of deposition and composition of collagen fibers,the expression level of factor Ⅷ,the level of transforming growth factor (TGF)-beta1 and the content of hydroxyproline were analyzed by Masson,immunofluorescent and immunohistochemistry staining as well as enzyme linked immunosorbent assay.Chi square test,one-way analysis of variance (ANOVA),least significant difference (LSD) method,Dunnett's T3 and Kruskal-Wallis test and other method were used for comparison.Results After treatment,18 patients of combination therapy group (21 patients) had regular microvessel nets (85.7％),which was significantly more than those of single therapy group (12 cases,57.1％) and healthy control group (10 cases,47.6 ％),and the differences were statistically significant (x2 =4.200,P=0.040).In the comparison of maturity of regenerative mucosa between combination therapy group and single therapy group after treatment,the ration between collagen type Ⅰ and Ⅱ,deposition of collagen fibers,the number of factor Ⅷ positive cells,the level of TGF-beta1 and the content of hydroxyproline were 36.05 and 23.14;269 375.63.± 171 608.63 and 137 693.14±98 330.93;34.91±8.40 and 28.24±6.93;104 498.71±40 487.96 and 70 757.11±19 323.95;(1 897.80±879.35) and (1 230.57±536.05) μg/L,respectively;while in healthy control group,the above parameters were 36.81,245 696.90 ± 224 687.00,23.10 ± 8.40,94 048.04 ±41 306.55 and 1 681.20 ± 423.61 μg/L,and the differences were statitically significant among these three groups (H=7.375,F=3.465,11.680,5.190,5.160;all P＜0.05).Those parameters of combination therapy group were significantly higher than those of single therapy group (H=2.416,LSD method;all P＜0.05).Conclusion Hydrotalcite combined with esomeprazole in the treatment of gastric ulcer could significantly improve microvessel morphology,maturity degree of regenerative mucosal structure and function,and the mucosal healing quality was also superior to single esomeprazole group.
