Hepatic epithelioid hemangioendothelioma is a rare and low-grade malignant tumor of vascular origin.Clinical symptoms and laboratory findings are unspecific.The definitive diagnosis can only be made by histopathalogi-cal investigation The primary treatments of choice are radical hepatic resection or liver transplantation. The role of differ-ent adjuvant therapies for patients with hepatic epithelioid hemangioendothelioma remains to be determined.

Objective To explore the change of platelet activation before and after stent implantation in acute coronary syndrome. Methods Detection of positive expression of platelet membrane glycoprotein CD62p,CD63 and thrombin-sensitive protein (TSP) were performed using flow cytometry (FCM) in 82 patients which included 45 unstable angina pectoris (UAP) and 37 acute myocardial infarction (AMI). Another 45 angiographically normal patients served as the control. Results Expression of CD62p, CD63 and TSP after stent implantation in ACS group. On the other hand, the expression of the above factors was higher in ACS group compared with the control group. Conclusion Acute thrombogenesis induced by platelet activation is a basic pathophysiologic process in ACS. Endothelial injury and plaque rupture produced by stent implantation may be a cause of platelet activation.

Objective: To investigate the induction of Tca8113 cells to apoptosis by fadd gene.Methods: RT PCR and recombinant PCR were used to amplify human fadd gene and cloned into expression vector pcDNA3 and pIRES2 EGFP, then transfered into Tca8113 cells. The growth and apoptosis of the cells were tested by cell counting,fluorescent microscopy, electron microscopy and flow cytometery. Results: fadd gene was obtained and transfered into Tca8113 cells. After transfection of the gene the growth of the cells was inhibited by 25%～52%, cell number in G 1 phase increased and that in S phase decreased. Apoptosis of the cells was observed. Conclusion: fadd gene can effectively inhibite cell growth and induce Tca8113 cells to apoptosis.

Obstract: Objective To study the effect of Guyanding Decoction(GYD) on the metabolism of oxygen-derived free radicals in the chicken model of knee osteoarthritis and to explore its therapeutic mechanism.Method Forty chickens were randomized into 5 groups: normal group,model group,low-dose GYD group,high-dose GYD group and Fenbid group.Low-dose group was administered 5 g/kg GYD and high-dose group with 10 g/kg GYD by gastric gavage.Fenbid group was given Fenbid 0.15 g/kg.The SOD activity and the MAD content in serum were detected in each group.Result The activity of SOD in model group was significantly lower than that in normal group(P 0.05).For the content of MDA,model group had a higher level than normal group(P 0.05).Conclusion The decoction of GYD exerts curative effect on experimental osteoarthritis by improving the activity of SOD,eliminating excessive oxygen-derived free radicals,decreasing the content of MDA,and preventing osteoarthritis patients from the injury of oxygen-derived free radicals.

Objective To explore the clinical features of adrenocortical oncocytoma for better understanding. Methods A total of 586 patients with adrenal cortical adenoma were retrospectively analyzed in our hospital from January 1993 to November 2009, in which 18 were diagnosed as adrenal cortical oncocytoma pathologically, with 7 male and 11 female, aged ( 45.5 ± 15.9 ) years, and the disease course of( 13.3 ± 13.1 )months. Results 6 patients suffered from Cushing's syndrome, 2 primary hyperaldosteronism, 1 had clinical features of both Cushing's syndrome and primary hyperaldosteronism, and 9 were nonfunctional. 4 cases were misdiagnosed as pheochromocytoma preoperatively. All 18 patients were diagnosed by B-mode ultrasound and operation ( 13 by laparoscopy, 5 by laparotomy). 11 tumors were located in the left adrenal while 7 in the right, with the average tumor size of 5.6 cm in diameter. Histopathologically, 1 was oncocytic adrenocortical carcinoma, while 17 were adrenocortical oncocytoma, in which 5 were potentially malignant and 12 were benign. 11 patients were followed up for 20.5±20.1 months. 2 patients were dead, and 9 were alive with tumor recurrence in 1 case.ConclusionsAdrenocortical oncocytoma is a pathological diagnosis and the clinical manifestations are various. The tumors are usually large in size, and can easily be found by ultrasound, but may be wrongly diagnosed as pheochromocytoma.Being different from previous reports, the majority of these patients present with endocrine dysfunction. Most of these cases are benign, but malignant potential is obvious. Therefore,follow-up is very important.

Objective To identify the types,frequency and risk factors of major complications using microwave ablation (MWA) to treat liver malignancies in a single center.Methods Using the electronic medical record system,patients with liver cancer who were treated with MWA from January 2010 to November 2015 were retrospectively studied,and the risk factors of severe complications were analyzed.Results Of the 7 403 patients who were treated with MWA (12 558 ablations).96 cases experienced severe complications (1.3％) and 5 patients died (0.07％).The complications included liver abscess (n ＝ 34,0.46％),pleural effusion (n ＝ 20,0.27％),bile duct injury (n ＝ 15,0.20％),hemorrhage (n ＝ 6,0.08％),liver failure (n ＝ 6,0.08％),extrahepa-tic organ injuries (n ＝ 5,0.07％),cancerous cells implantation of abdominal walls (n ＝ 2),cardiac arrest (n ＝ 1),vascular thrombosis (n ＝ 1),renal insufficiency (n ＝ 1),and patients with other associated diseases which developed after the MWA therapy (n ＝2).Metastatic liver cancer and earlier treatment of MWA sessions were associated with a higher major complication rate (P ＜ 0.05).Conclnsions MWA is a well-tolerated local treatment for liver cancer,with an acceptably low incidence of severe complications.Liver abscess was the most common postoperative severe complication.The surgeons＇ experience and tumor type were associated with the incidence of severe complications,however,not relavant with the frequency of preoperative ablations.Appropriate measures can be taken to effectively reduce the risk of serious complications.

BACKGROUND:Bone marrow mesenchymal stem cel transplantation for myocardial infarction becomes popularized in recent years, but transplanted cels cannot survive and proliferate under early inflammatory reaction or local ischemia/hypoxia microenvironment, eventualy hampering the therapeutic outcomes.
OBJECTIVE:To investigate the therapeutic effect of PTEN-silenced bone marrow mesenchymal stem cels on acute myocardial infarction.
METHODS:(1) Bone marrow mesenchymal stem cels from Sprague-Dawley rats were randomly assigned to receive no treatment, NCsiRNA transfection using Lipofectamin2000orPTEN siRNA transfection using Lipofectamin2000. Cel growth curves were described using MTT method to detect cel cycle using flow cytometry. (2) Thirty Sprague-Dawley rats were selected to prepare myocardial infarction models that were randomized into three groups (n=10 per group): blank control, negative control and RNAi group. Six hours after modeling, bone marrow mesenchymal stem cels transfected with nothing, NCsiRNA and PTEN siRNA were respectively injected into the infarcted center of the left ventricular anterior wal in these three rat groups. After 4 weeks, al rats were subjected to cardiac function detection using echocardiography, and the survival and proliferation of bone marrow mesenchymal stem cels in the rats were observed by fluorescence microscopy.
RESULTS AND CONCLUSION:Compared with the other two groups, a significant increase in the absorbance values at different culture time, the proportion of cels in S+G2phase, and the number ofbone marrow mesenchymal stem cels in the myocardial tissue was found in the RNAi group (alP< 0.05). Additionaly, the left ventricular ejection fraction and left ventricular shortening fraction were significantly reduced in the RNAi group than the blank control and negative control groups at 4 weeks after cel transplantation (P< 0.05). Bothin vivoandin vitroexperimental findings showed that PTEN silencing could effectively improve cel survival and proliferation in the infarcted myocardium. Moreover, in thein vivoexperiment, an overt improvement in rat’s cardiac function was achieved.
