Objective To assess the radiological imaging findings of hepatic inflammatory myofibroblastic tumor and to discuss the appropriate morphological classification.Methods A total of 22 patients with hepatic inflammatory myofibroblastic tumor confirmed by pathology were enrolled.Imaging performance of hepatic inflammatory myofibroblastic tumor were analyzed and the lesions were classified into appropriate type based on the imaging findings.Results Totally 23 lesions were found in 22 patients.The typical imaging features included great enhancement at later phase (13/20),moth eat en central necrosis (12/23) and peripheral shell (12/23).Seed in fruit was the most typical classification (8/23),followed by Seedless fruit (7/23).Conclusion Hepatic inflammatory myofibroblastic tumur typically shows as a single nodular lesion with moth eaten necrosis and peripheral shell like a Seed in fruit.The enhancement at later phase (especially the peripheral enhancement) can be regarded as a particular feature.

Hepatocellular carcinoma ( HCC ) is one of the commonest malignant tumors in China .The therapeutic effects of conventional therapies including surgery resection at early stage ,chemotherapy or radiothera-py are greatly less than expected .One of the most possible reasons is the blockage of apoptosis in HCC cells .This review collects literatures about the studies on the roles of key signal pathways including RA ,STAT3,PDT,p53,β-catenin,TRAIL,microRNA and RAS in HCC therapy .This study may contribute greatly to providing outline in-sights for using apoptosis induction in liver cancer therapy .We hope it can promote the development liver cancer therapy in China .

Objective This study aimed to investigate the incidence and the cause for duodenalbiliary reflux and reflux cholangitis after metallic stent placement in distal common bile duct Methods After percutaneous transhepatic bile duct puncture and biliary outside drainage was performed, 16 cases with malignant distal biliary stricture underwent metallic stent placement in distal common bile duct Before stent placement, the routine laboratory studies including leukocyte, neutrophil percentage and the levels of total bilirubin and direct bilirubin in blood were performed for all patients. Two to five days [ an average of (3.3 ±0. 9) days ] after stent implantation, the above indexes were tested again, and 1 ml of water containing 185 MBq of 99Tcm-DTPA was given orally before extubation, then 99Tcm radioactivity in the bile was detected 2 hours later. For the measurement data obtained from the experiment, t test or Wilcoxon signed rank test was adopted to compare them, and P ＜ 0. 05 was considered to be statistically different Results In 14 cases, radioactivity was successfully detected in the bile 2-5 days after stent implantation. Twelve of them was detected to have radioactivity in the bile 2 hours before extubation with duodenal-biliary reflux. The technetium count in the bile accounted for 1.82% of the total intake dose. There was no radioactivity in the bile in 2 cases. In 14 patients, there were no symptoms of cholangitis such as high fever, chills, increased jaundice, and so on after stent implantation. The mean of white blood cell count was (7.59 t2. 62) × 109/L, and the median of neutrophil percentage was 0. 74. Compared with those before stent implantation, the difference did not reach statistical significance ( t = 0. 423, Z = 1. 036, P ＞ 0. 05 ).After stent implantation, the median of total bilirubin and direct bilirubin were significantly lower, which were 92. 2 and 74. 3 μmol/L. Compared with those before stenting,the difference was statistically significant (Z= -3. 170, -3. 170, P ＜0.05). Conclusions There is a high incidence of duodenal-biliary reflux after stent implantation in distal common bile duct in the early stage. However, there is no simultaneous cholangitis caused by duodenal-biliary reflux.

Objective To explore the method and value of percutanously interventional therapeusis for treatment of obstructive jaundice caused by hepatocellular carcinoma accompanied with bile duct thrombosis.Methods Sixteen cases with bile duct thrombosis proved by pathology and imaging examinations were retrospectively analyzed.According to the clinical symptoms, all the patients received percutaneous transhepatic biliary drainage (PTBD) including permanent external drainage, temporary internal drainage and implantation of covered stents.Serum total bilirubin (TBIL) after the interventional therapeusis were measured and compared with that before the treatments by t test to evaluate the efficacy of these treatments.The relief of clinical symptoms was also reviewed to evaluate the efficacy of these treatments.The patients were followed up within 2 years.Results The PTBD was successfully performed in 16 cases.Permanent external drainage, temporary internal drainage and implantation of covered stents were performed in 2 patients, 7 patients and 7 patients respectively.TBIL after the interventional therapy decreased significantly (t=7.366, P<0.01) to (161.2±80.5) μmol/L averagely from (261.9±77.2)μmol/L before the treatments.All the patients died before the end of followed-up.The average survival time was 204 days (30 to 391 d)and the median survival time was 200 days.Bleeding and infection were the main complications, which could be controlled successfully by routine treatments.Conclusion With high achievement ratio and good efficacy, percutanously interventional therapeusis are good choices for the treatments of obstructive jaundice due to bile duct thrombosis.

Objective To investigate the association of tumor necrosis factor-alpha (TNF-α) gene promoter region - 1031T/C and its combination with interleukin-6 (IL-6 ) gene promoter region -634C/G single nucleotide polymorphisms (SNP) with the genetic susceptibility to endometriosis.Methods Total of 432 endometriosis patients and 499 non-endometriosis women who had received an operation due to tubal ligation,tubal recanalization,laparoscopic hydrotubation,ovarian simple cyst and teratoma were collected and separated into endometriosis group and control group,that all cases were confirmed by operation and pathology.A case-control study was performed in endometriosis and control group to evaluate the association of these SNP with the susceptibility to endometriosis by using a fluorescent quantitative PCR-based high resolution melting ( HRM ) method.Results ( 1 ) TNF-α - 1031T/C genotype:the T and C of TNF-α - 1031T/C allele frequencies in the endometriosis group and control group were 79.2％ (684/864),20.8％ (180/864) and 81.8％ (816/998),18.2％ (182/998),respectively.The TT,TC and CC of TNF-α - 1031T/C genotype frequencies in the two groups were 63.7％ (275/432),31.0％ ( 134/432 ),5.3％ (23/432) and 66.5％ (332/499),30.5％ (152/499),3.0％ ( 15/499),respectively.There were no statistical significances in the TNF-α - 1031T/C alleles and genotypes distributions between the two groups ( P =0.158,P =0.186 ).( 2 ) TNF-α - 1031T/C and IL-6 - 634C/G conjoint genotypes:to research on the TNF-α - 1031T/C and IL-6 -634C/G genotypes for conjoint analysis,the TT + CC,TC + CC,CC +CC,TT + CG,TC + CG,CC + CG,TT + GG,TC + GG and CC + GG combination genotype frequencies in the two groups were 39.4％ ( 170/432 ),19.4％ ( 84/432 ),4.6％ ( 20/432 ),20.6％ ( 89/432 ),8.8％ (38/432),0.9％ (4/432),3.5％ (15/432),2.3％ (10/432),0.5％ (2/432) and 36.7％ ( 183/499),17.4％(87/499),1.4％ (7/499),26.1％ (130/499),10.4％ (52/499),1.2％ (6/499),3.8％ (19/499),2.6％ ( 13/499),0.4％ (2/499),respectively.There were no statistical significances in the combination genotypes distributions between the two groups ( P =0.107 ).As compared with carriers of TT + CC combination genotype,the endometriosis risk of carriers of CC + CC combination genotype enhanced 3.076 times ( 95％ CI:1.268 - 7.457,P =0.009 ),and the endometriosis risk of carriers of other combination genotypes were no statistical significances (all P ＞ 0.05 ).ConclusionsThe study demonstrates that there are no significant association between the SNP of TNF-α - 1031T/C and genetic susceptibility to endometriosis.However the results indicate that there are significant association betweengenetic susceptibility to endometriosis and the combination polymorphisms of TNF-α -1031T/C and IL-6- 634C/G.

Objective To discuss the clinical value of interventional management before surgical therapy for massive gastrointestinal hemorrhage, and to compare the clinical efficacy and re-bleeding rate between hypophysin infusion group and embolization group. Methods During the period of June 1998-Apr.2009, 31 patients with massive gastrointestinal hemorrhage in our institution underwent preoperative interventional managements before they received surgical treatment. According to DSA manifestations, the patients underwent trunsarterial hypophysin infusion or transcatheter embolization as interventional management. The clinical efficacy of interventional procedures and its influence on the surgery were evaluated, and the hemostasis rate and re-bleeding rate were compared the two kind of intervention managements. The numeration data were analyzed with Fisher's exact test, and the SPSS 11.0 was used as statistical software. Results The interventional managements were successfully performed in all the 31patients, with a total hemostasis rate of 83.9% (26/31) and a total re-bleeding rate 30.7% (8/26). The hemostasis rate and re-bleeding rate of hypephysin infusion group and embolization group were 69.2% (9/13), 94.4% (17/18) and 44.4% (4/9), 23.7% (4/17), respectively. All the 31 patients received surgery after interventional therapy, of which selective operation was carried out in 20. Neither surgery-related or intervention-related serious complications nor death occurred. Conclusion Preoperative interventional managements can provide patients with massive gastrointestinal hemorrhage with valuable chance of a successful surgery, enable the physician to take a selective operation to replace an emergency one, as a result, the surgical risk will be greatly reduced. Therefore, it is worth popularizing the preoperative interventional managements in clinical practice.
