BACKGROUND: Homocysteine (HCY) has been verified as an independent risk factor of atherosclerosis and atherothrombosis of cardiovascular disease.OBJECTIVE: To observe the effects of HCY on the secretion and activity of matrix metallopotinase-1 (MMP-1) and tissue inhibitors of metalloproteinase-1 (TIMP-1) in vascular smooth muscle cells (VSMCs).DESIGN : Auto-control observation.SETTING: Pathology Room, Institute of Regeneration Medical Sciences, Jilin University.MATERIALS: In vitro cultured vascular smooth muscles cells (VSMCs) of rats were obtained from male Wistar rats with the body mass of about 150 g from weeks 4-6 supplied by Laboratory of Animals, Norman Bethune Medical Sciences Division, Jilin University.METHODS: The experiment was performed at the Pathology Room, Institute of Regeneration Medical Sciences, Jilin University from May 2001 to May 2003. VSMCs ofin vitro cultured rats were adopted and divided into 5 groups, 0(control group), 0.10, 0.25, 0.50 and 1.00 mmol/L HCY were added, respectively for 48 hours. Effect of HCY on activity of MMP-1 was observed with zymography. The secretions of MMP-1 and TIMP-1 and their mRNA expressions were studied with Western blot and semi-quantitative reverse transcription polymerase chin (RT-PCR).MAIN OUTCOME MEASURES: Activity of MMP-1, secretions of MMP-1 and TIMP-1 and their mRNA expressions.RESULTS: ①Secretions of MMP-1 and TIMP-1: The secretion of MMP-1 in the 0.25, 0.50 and 1.00 mmol/L HCY groups was lower significantly than that in the control group (P < 0.05-0.01). The secretion of TIMP-1 in the 0.10, 0.25, 0.50 and 1.00 mmol/L HCY groups was higher than that in the control group (P< 0.05-0.01). ②The MMP-1 activity decreased with the increase of HCY, but reduced obviously in the 0.50 and 1.00 mmol/L HCY groups (P < 0.01). ③The expression of MMP-1 mRNA in the 4 HCY groups was lower markedly than that in the control group (P < 0.01). The expression of TIMP-1 mRNA in the 0.25 mmol/L HCY group was higher than that in the control group (P < 0.05), and it was higher remarkably in the 0.50 and 1.00 mmol/L HCY groups than that in the control group (P < 0.01).CONCLUSION: HCY can inhibit enzyme activity, decrease collagen degradation and induce collagen accumulation by inhibiting the secretion of MMP-1, which indicates that reduction of collagen degradation induced by HCY is one of the pathogenesies of atherosclerosis.

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.

Objective To study the diagnosis,prophylaxis and treatment of splenic artery steal syndrome (SASS),and to evaluate their clinical outcomes in recipients who underwent orthotopic liver transplantation (OLT).Methods 1 385 consecutive patients who suffered from liver cirrhosis and had undergone OLT in our hospital between Jan,2004 and Dec,2013 were studied.We hypothesized that patients were at risk of SASS when the calibre of the splenic artery (SA) was 1.5 times larger than the common hepatic artery (CHA) together with splenomegaly (318 patients,23.0%).Further surveillance with Doppler ultrasound (DUS) was carried out immediately at CHA reperfusion during operation.When a sluggish peak systolic velocity (PSV) < 30 cm/s or no flow was detected in a patent hepatic artery,prophylactic SA banding (SAB) was considered.127 patients (39.9%) who fulfilled these criteria were recruited to the intervention group to undergo SAB.Eventually,patients who developed SASS were treated with coil-embolization of the SA (SAE),re-anastomosis of the HA to aorta (HTA),ligation of SA (SAL) or splenectomy (SPT),or retransplantation.Results SAB resulted in immediately increase in the mean PSV of the HA from 19.3 ±5.5 cm/s to 45.9 ± 9.1 cm/s (P < 0.05),and resistance index (RI) of the HA rehabilitated to reasonable levels (0.5 ~0.8),without any HA or biliary related complication in all the 127 patients.17 patients in the control group were identified to have SASS (8.9%).5 of these 17 patients required emergency treatment by coil-embolization.Of the remaining 12 patients,11 who developed hepatic artery thrombosis secondary to SASS required to undergo embolectomy or thrombolysis followed by HTA (4 patients),SAL (3 patients),SPT (5 patients).Three of these patients finally required re-OLT.All these patients obtained acceptable results by these salvage strategies,except 2 out of the 12 patients who died from liver failure.Conclusions SASS is an important but it is often and under-diagnosed cause of graft ischemia after OLT.Prophylactic SAB should be introduced to patients at risk of developing SASS in order to obtain satisfactory results.Coil-embolization of SA shortly after diagnosis is an effective salvage intervention to prevent further progression to develop devastating consequences.
