Hepatocellular carcinoma(HCC) is one of the most common devastating neoplasms worldwide with very poor prognosis.Recent studies have identified a CpG is land methylator phenotype(CIMP),which was characterized by simultaneous methylation of multiple TSGs.CIMP has been observed in multiple human malignant tumors including HCC.CIMP also plays a critical role in HCC carcinogenesis,progression,metastasis and recurrence. Therefore,detection of the methylation status of tumor-related genes can provide key information for early diagnosis,molecular classification and predicting prognosis of HCC.

Objective To assess the Chinese System for Cardiac Operative Risk Evaluation (SinoSCORE) model in patients undergoing heart valve surgery at our center.Methods From January 2009 to December 2011,2098 consecutive adult patients who underwent heart valve surgery at our center were collected and scored according to the SinoSCORE model.All patients were divided into three risk subgroups.The entire cohort and each risk subgroup were analysed.Calibration of the SinoSCORE model was assessed by the Hosmer-Lemeshow(H-L) test.Discrimination was tested by calculating the area under the receiver operating characteristic (ROC) curve.Results Observed mortality of all 2098 patients was 3.00％.Despite there were significant differences between the SinoSCORE population and our own population sample,the SinoSCORE model showed good calibration(Hosmer-Lemeshow:P =0.783) and discriminative power (area under the ROC curve of 0.752)in predicting in-hospital mortality at the entire cohort.Conclusion The SinoSCORE model give an accurate prediction for individual operative risk in heart valve surgery patients at our center.

Objective By analyzing the epidemiological characteristics of brucellosis in Shanxi Province,to provide a scientific basis in formulation of strategies for effective prevention and control of the disease.Method Surveillance data of human brucellosis from China Information System for Disease Control and Prevention between 2004 and 2013 were statistically analyzed by descriptive epidemiological method.The regional,time,age and sex,occupational distribution of brucellosis were analyzed.The prevalence trend of brucellosis in Shanxi Province was summarized.Results From 2004 to 2013,the total incidence presented a rising tendency and the highest reported incidence was 19.10/10 million in 2013.A total of 43 061 cases of brucellosis occurred in Shanxi Province.The average incidence of brucellosis was 12.52/10 million.Regional distribution range was relatively focused on the north areas of Shanxi Province,the number of reported cases of Datong City was the largest (12 157 cases),being 28.23％.The incidence of Shuozhou City was the highest (42.97/10 million).The epidemic was spreading through all county areas.The disease was found each month throughout the year,the obvious incidence peak seasons were between March and June.The disease was most commonly found in 15-64 age groups(87.19％,37 545/43 061).Occupation distribution of patients was mainly farmers (83.34％,35 887/43 061).Conclusions The situation of brucellosis epidemic in Shanxi Province is relatively serious;the reported incidence of brucellosis in Shanxi Province is in a rapid upward trend year by year,even highly active in some particular areas.Different regions should establish regional mechanisms for joint prevention and control and implement different prevention and control measures to comprehensively and sequentially control brucellosis.

BACKGROUND:Our preliminary study found that the monocusp valves made of ultramicropore expanded
polytetrafluoroethylene (ePTFE) revealed no significant thrombus, calcification, or degradation 20 weeks after implanted into the descending aorta and the left pulmonary artery in sheep, which verified the good property of ePTFE. However, the surface of ePTFE in the left pulmonary artery was covered with obvious neointima.
OBJECTIVE: To assess the biocompatibility of phosphorylcholine-coated ePTFE.
METHODS:ePTFE surface was modified by phosphorylcholine derivative. Then the changes of surface shape, tensile stress at yield and elasticity modulus, water contact angle, and protein absorption capacity of ePTFE after surface modification were observed. (1) Hemolytic test: the leaching solution of phosphorylcholine-coated ePTFE, leaching solution of uncoated ePTFE, normal saline, and distiled water were added to the diluted human blood, respectively. (2) Platelet count test: the phosphorylcholine-coated ePTFE, uncoated ePTFE, high density
polyethylene, and Zymosan A were added to the whole blood samples from healthy volunteers, respectively.
(3) Platelet activation test: the phosphorylcholine-coated ePTFE, uncoated ePTFE, γ-Globulins, and Zymosan A
were added to the whole blood samples from healthy volunteers, respectively.
RESULTS AND CONCLUSION: The mean micropore diameter of ePTFE was significantly decreased after
phosphorylcholine coating (P < 0.001). The hydrophilicity and the ability of suppressing protein adsorption were
significantly strengthened after phosphorylcholine coating (P < 0.001). Phosphorylcholine coating did not influence
ePTFE in biomechanical properties and hemolytic test. The platelet count test and platelet activation test demonstrated that phosphorylcholine coating significantly improved anti-thrombus function of ePTFE. So, phosphorylcholine coating can enhance anti-thrombus function, suppress protein adsorption, and improve biocompatibility of ePTFE.

Objective To investigate the surgical technique and clinical outcomes of reconstruction of the annulus and the intervalvular fibrous body during valve replacements. Methods Fifty-nine patients underwent reconstruction of the annulus or the intervalvular fibrous body during the valve replacement. Indications for the operation were small aortic annulus which may cause patient/prosthesis mismatch in 43, active infective endocarditis with the abscess in the periannulus tissue in 13, extensive calcification of the aortic annulus in 2 and an active bleeding complication of the aortic root after aortic and mitral valve replacement in 1. The reconstruction was done with fresh autologous pericardium. Results The aortic clamping time in reconstruction of the intervalvular fibrous body with double valve replacement was longer than that of the regular double valve replacement. Four patients died in the perioperative period, giving an overall in- hospital mortality of 6.7%. Postoperative complication were: re-sternotomy for bleeding in 2, Ⅲ degree A-V block in 2, respiratory dysfunction in 2, and acute renal failure in 2. Patients were followed up for 6 months by echocardiography study, and no periannular leakage was found. Conclusion Reconstruction of the annulus is an effective technique for patients with a small aortic annulus, extensive calcification of the interventricular fibrous body and active infective endocarditis with abscess. Although the operative procedure is challenging and taking more time, the technique is safe and reproducible.

Objective The results of Aortic valve replacement (AVR). Combined with ascending aortic replacement(group A) or aortoplasty (group B) in patients with aortic valve disease and ascending aortic dilatation were analysed to assess the clinical outcomes and respective indications. Methods Among the two groups, the age, gender, NYHA class, types of aortic valve lesions and left ventricular ejection fraction were not different statically. The ascending aortic diameters in group A[(50.41 ±3.71) mm] and group B [(48.29±2.18) mm] were not statically different. Ascending aortic replacement was performed in Group A. A Dacron tube(diameter 28 ～ 30mm) was routinely wrapped around the ascending aorta after aortoplasty in group B. Results There was 1 postoperative death in group B, blood transfusion volume and postoperative complications were not stasticaly different in the two groups. Cardiopulmonary bypass time [(110.52 ± 27.51) min] and aortic across clumping time [(71.70 ± 17.13)min] in group A were significantly longer than that of group B [(97.31 ± 19.46) min,P=0. 004; (57.13 ±19.46) min, respectively. P=0.025]. Conclusion Aortic valve disease, especially bicuspid valve disease often combines with ascending aortic dilatation or aneurysm. In younger patients, ascending aorta should be actively treated surgically when the diameter is equal or more than 40mm. Aortoplasty with external reinforcement of a Dacron tube is simpler and safer than aortic replacement in patient without aortic atherosclerosis or ulceration, and large aneurysm.

Objective To discuss the diagnosis and surgical treatment of the primary right ventricular tumors.Methods The results of surgical treatment of 7 patientss (5 males,2 females; median age,48 years,range,37 to 68 years) with primary right ventricular tumors hospitalized from Jan,1999 to May,2012 were analyzed.By preoperation echocardiography,cardiac myxoma was diagnosed in 2 cases,and cardiac space-occupying lesion was diagnosed in 5 cases.Median sternotomy were performed in all the 7 cases for biopsy or resection of tumor.when resection of tumor,extracorporeal circulation and cardiac arrest were performed.Results The 7 patients accounted for 4.96％ of patients with cardiac tumors surgically treated in the corresponding period.Complete resection of tumor was performed in 5 cases,and only biopsy in 2 cases.The pathological diagnoses included myxoma in 2 cases,lipoma in 1 case,liomyoma in 1 case,undifferentiated sarcoma in 1 case,and mesenchymal sarcoma in 2 cases.There was no in-hospital death.During a follow-up of 1 ～ 51 months (median,38 months),the 3 cases of sarcoma died,and the other patients were good and showed no recurrence.Conclusion The incidence rate of primary right ventricular malignant tumor is relatively high.Echocardiography is the most important diagnosis method.The prognosis of right ventricular malignant tumor is poor.The results of surgical treatment of right ventricular benign tumor are satisfactory.

Objective To evaluate valvular functionality after transcatheter pulmonary valve replacement in sheep using a novel polymeric prosthetic pulmonary valve.Methods In this study,we designed a novel polymeric trileaflet transcatheter pulmonary valve with a balloon-expandable stent,and the valve leaflet was made of 0.1 mm expanded polytetrafluoroethylene (ePTFE).We chose bovine pericardium valve as control.Pulmonary valve stents were implanted in situ by right ventricular apical approach in 8 healthy sheep(6 for polymeric valve and 2 for bovine pericardium valve) weighing an average of(22.8 ± 2.2) kg.Angiography was performed after implantation to assess immediate valvular function.Color Doppler echocardiography and 64-row computed tomography were used to assess valvular function 4 weeks after implantation.Results Implantation was successful in 8 sheep.Angiography at implantation showed one polymeric valve was located below the ideal position and most of the stent was in the outflow tract of right ventricle.While,all the other prosthetic valves demonstrated orthotopic position and exhibited normal open and close functionality.Echocardiography 4 weeks after implantation showed all the prosthetic valves exhibited normal functionality and no significant insufficiency.The peak-peak transvalvular pressure gradient of the polymeric valves was (18.8 ± 6.0) mmHg,while that of two bovine pericardium valves were 9 mmHg and 20 mmHg.CT 4 weeks after implantation demonstrated orthotopic position of the stents except the above-mentioned one and all the stents had no deformation.Conclusion The success rate of transcatheter pulmonary valve replacement by right ventricular apical approach is satisfactory.The early valvular functionality of the novel ePTFE pulmonary valve after transcatheter pulmonary valve replacement in sheep is good.
