Objective To test the hypothesis that IL-10 may promoting left ventricular remodeling and cardiac function by modulating extracellular matrix after acute myocardial infarction. Methods Male adult rats were randomly divided into three groups: control group (n=6) , MI/AAV2 group (n=16) and MI/AAV2-IL-10 group (n=16). Establishing animal modol of experimental myocardial infarction and recombinant adeno-associated virus type 2 (AAV)/IL-10 (AAV2-rhIL-10) and AAV2 were injected around the ischemic zone. Echocardiography parameters, hemodynamic parameters, left ventricular mass index (LVMI) , collagen volume fraction (CVF) , perivascu-lar circumferential area (PVCA) , collagen type Ⅰ & Ⅲ volume fraction and mRNA levels of collagen type Ⅰ & Ⅲ , matrix metalloproteinases-2 ( MMP-2 ) and tissue inhibitor of metalloproteinase-1 ( TIMP-1) were compared among the three groups. Results Improved cardiac function was observed in MI/AAV2-IL-10 group shown by echocardiography and hemodynamic examination. Four weeks after myocardial infarction, thickness of different parts of LV was not different in MI/AAV2-IL-10 group and MI/AAV2 group. Nevertheless CVF, PVCA and collagen type Ⅰ volume fraction was significantly descending in remote zone of MI/AAV2-IL-10 group compared with that of MI/ AAV2 group. The mRNA expression of collagen type I and MMP-2 was lower in MI/AAV2-IL-10 group than that in MI/AAV2 group. Conclusion Recombinant IL-10 expression mediated by AAV2-rhIL-10 transfection of rats' myocardium promotes LV remodeling and cardiac function after acute myocardial infarction. The promotion was partially achieved by inhibition myocardium collagen deposition.

Objective To examine the effects of IL-10 on cardiac fibroblasts ( CFBs) proliferation and phenotype transformation to myofibroblasts (MyoFbs) induced by transforming growth factor-β1 (TGF-β1);and to investigate the regulating pathways .Methods Cardiac fibroblasts were isolated from cardiac ventricles of neonatal SD rats . The passage 2~4 were used and divided into the following groups for treatment:1) control group, 2) IL-10 reac-tion group, 3) TGF-β1 reaction group, and 4) IL-10 plus TGF-β1 reaction group (TGF-β1 treatment followed with IL-10 pretreatment ) .Cells proliferation was assessed by MTT assay and immunocytochemistry staining for prolifera-ting cell nuclear antigen (PCNA);the phenotype transformation into MyoFbs was assessed by immunocytochemistry of α-smooth muscle actin (α-SMA);extracellular signal related kinase ( ERK1/2) and P38 kinase pathways were assessed by western-blot.Results TGF-β1 (10 μg/L) treatment boosted the proliferation and the expression ofα-SMA significantly (P<0.01), while IL-10 (10, 50 or 100 μg/L) plus TGF-β1 co-treatment induced lower cell proliferation and expression of α-SMA than treating with TGF-β1 alone ( P<0.05 ) , with the inhibitory effect of IL-10 being concentration dependent .TGF-β1 could significantly stimulate the ERK 1/2 and P38 kinase phospho-rylation ( P<0.01 ) , however IL-10 (100 μg/L) plus TGF-β1 co-treatment failed to down-regulated the phospho-rylation of ERK1/2 and P38 kinase compared with TGF-β1 alone ( ERK1/2:P<0.05;P38:P<0.01 ) .Conclu-sions IL-10 can attenuate TGF-β1-induced CFBs proliferation and phenotype transformation to MyoFbs .The in-hibitory effects may explained by a mechanism of inhibiting the activation of ERK 1/2 and P38 kinase .

Methods 62 patients with nerve-root type cervical spondylopathy were divided into treatment group (n=31),whom were treated with pulsed radiofrequency combined with acupuncture and traction, and the control group (n=31) only with acupunctureand traction. Results The incidence of effect was significantly higher in the treatment group than in the control group (P<0.01). ConclusionCombining with pulsed radiofrequency is more effective on nerve-root type cervical spondylopathy than acupuncture and traction only.

[ ABSTRACT] AIM: To determine the aberrant methylation status in the gene promoter regions of CDH13, RASSF1A, DLEC1, SEPT9 and RUNX3 by detecting the plasma specimens and the value of their combined detection for di-agnosis of lung cancers.METHODS:Nest methylation specific PCR ( nMSP) was used to detect the promoter methylation status of the 5 genes in the plasma from 106 normal controls, lung cancer tissues, lung benign tissues and the plasma from 106 patients with lung cancers.Multiple displacement amplification ( MDA) was used to amplify modified genomic DNA to solve the problem of insufficient of plasma DNA template.RESULTS: The positive rates of promoter methylation of CDH13, RASSF1A, DLEC1, SEPT9 and RUNX3 in the lung cancer tissues were 51.9%, 44.3%, 54.7%, 36.8%, 24.5%, respectively, and those in the plasma were 46.2%, 41.5%, 50.9%, 31.1%, 19.8%, respectively.The re-sults of the Kappa consistency check showed that the lung cancer tissues and the plasma had obviously coherence in the methylation status of the 5 gene promoter regions.Combination of DLEC1, CDH13, RASSF1A, and SEPT9 had a higher di-agnostic efficiency than the others, as their ACC value was 0.8208 and youden index was 0.6415 ( with the sensitivity of 81.13% and the specificity of 83.02%) .CONCLUSION:Combination detection of promoter methylation of lung cancer-related genes in the plasma is expected to apply to the early diagnosis of lung cancer.

Objective To investigate the clinical characteristics,surgical experience and mid-term outcome of coronary artery bypass graft surgery in patients aged ≤ 40 years.Methods From Jan.,2009 to Dec.,2015,12 patients with median age of (37.9 ± 2.5) years (range 32-40 years,10 males) were diagnosed with coronary artery disease and underwent coronary artery bypass graft surgery at Zhongshan Hospital,Fudan University.The clinical characteristics included five cases with hypertension,three cases with diabetes mellitus,four cases with hyperlipemia,eight cases with smoking history,seven cases with myocardial infarction.Six cases had at least one branch totally occluded.Two cases once underwent percutaneous coronary intervention surgery and implanted with five and three stents respectively.The perioperative data and follow-up results were retrospectively analysed.Results There was no in-hospital death and no death during follow-up period.Surgical techniques included bilateral internal mammary arteries combined with radial artery were operated in six cases,bilateral internal mammary arteries combined with great saphenous vein in two cases,left internal mammary arteries combined with great saphenous vein in four cases,off-pump in nine cases and on-pump in three cases.The mean follow-up time was (47.8 ± 24.3) months.During the follow-up one case suffered with saphenous vein graft restenosis 5 years after the surgery and underwent percutaneous coronary intervention.Other cases were all alive and assessed New York Heart Association's function class Ⅰ-Ⅱ.Conclusions Younger patients usually suffer with severe coronary artery disease when diagnosed because they often have excellent compensative capacity and the pathogenesis is concealed.The mid-term results of coronary artery bypass graft surgery in patients aged ≤40 years are satisfactory.

Objective:To explore the effect of group visits on health condition among follow-up patients with chronic heart failure.Methods:Totally 126 outpatient follow-up patients with heart failure were divided into intervention group and control group by random number table from 2018 to 2019. The intervention group consisted of 63 cases and control group consisted of 59 cases. The intervention lasted 6 months. The intervention group received group visits, while the control group received routine outpatient follow-up. Medication adherence, quality of life and heart failure related indicators were evaluated at baseline and after 6 months of intervention.Results:At 6 months after intervention, the scores of medication adherence, total quality of life, body, emotion and others dimensions of the intervention group were (5.79±1.38), (30.11±8.22), (12.65±5.53), (5.24±4.57) and (12.22±4.76) points. These scores of the control group were (5.31±1.09), (37.26±9.02), (15.87±5.21), (7.03±5.14), (14.36±5.54) points. The differences between the two groups were statistically significant ( t values were -4.581-2.161, P<0.05 or 0.01). The BNP and proportion of New York Heart Association (NYHA) I the intervention group were (180.87±174.92) ng/L and 84.1% (53/63). These indicators of the control group were (351.02±268.13) ng/L and 67.8% (40/59). The differences between the two groups were statistically significant ( t value was -4.177, χ2 value was 4.484, P<0.01 or 0.05). Conclusions:Group visits program is an effective management mode to provide intensive patient education and foster peer support, improving medication adherence and quality of life of follow-up patients with heart failure.

Objective To assess the value of vascular endothelial growth factor (VEGF) expression in the prognosis of glioma patients.Methods PubMcd,EMbase,Cochrane Library,CNKI and Wanfang data were searched for collecting retrospective cohort studies on the correlation between VEGF expression and prognosis of glioma patients,and relevant articles were also retrieved from inception to June,2016.Two reviewers independently screened the literature,extracted the data,and evaluated the quality.Then Meta analysis was performed with RevMan5.3 software,and the publication bias of literature was evaluated by means of Begg's funnel plot and Egger's method.Results A total of 19 studies with 1657 cases were included.No significant publication bias was found in all groups.The analysis demonstrated positive associations between VEGF expression and poor prognosis (hazard ratio [HR]=1.39,95％CI:1.12-1.73),and the difference was statistically significant (P=0.003).Subgroup analysis showed that the high expression of VEGF in the European and American patients was more valuable than that in the Asian patients in the prognosis of gliomas;large samples of clinical studies of high VEGF expression were more valuable in the prognosis of gliomas than small samples.The detection of VEGF expression by different methods suggested that the patients with high expression of VEGF had poor prognosis;HR provided by the literature suggested that VEGF over-expression was associated with poor prognosis.Conclusion The expression of VEGF has predictive value for the survival time of glioma patients and VEGF can be recommended as a useful survival biomarker in clinical practice.
