Objective To investigate mut-slice spiral CT(MSCT) and MRI features and correlated pathological basis of stasis cirrhosis.Methods MSCT and MRI findings of 35 patients with stasis cirrhosis (study group) and 35 patients with posthepatitic cirrhosis (control group) were studied retrospectively. Volume index of liver and spleen, caliber of hepatic vein and the number of regenerative nodules exceeded 5mm in diameter were measured.The contrast-enhanced patterns of liver parenchyma, contrast medium reflux, ascites, the number of varices and correlated abnormalities were reviewed.Results The volume indexes of liver and spleen, calibers of hepatic vein were (4434.95±1283.08) cm~3,(621.92±400.33) cm~3 and (3.61±0.81) cm in the study group,(2569.73±853.06) cm~3,(1275.61±727.51) cm~3 and (1.92±0.46) cm in the control group,respectively.The number of the patients showed waves of borderline, inhomogeneous pattern of parenchymal contrast enhancement, regenerative nodules exceeded 5mm in diameter, contrast medium reflux, varices and ascites were 5, 29, 17, 20, 16 and 6 cases in the study group,29,0,5,0,35 and 26 cases in the control group,respectively,there were statistic differences between the study group and control group(P＜0.05).Conclusion MSCT and MRI play a invaluable role in the diagnosis and differential diagnosis and etiological diagnosis of stasis cirrhosis.

Objective To investigate multi-slice spiral CT (MSCT) and MRI features of stasis cirrhosis and the diagnostic value of MSCT and MRI. Methods MSCT and MRI findings of 35 patients with stasis cirrhosis were studied. The size of liver and spleen, the diameter of hepatic vein (HV), enhancement pattern of liver parenchyma, contrast medium reflux in inferior vena cava (IVC) and (or) HV, ascites, number of varices and correlated abnormalities were reviewed. Results The volume index of liver and spleen of 35 patients was 4 434.95 cm3 and 621.92 cm3 respectively. The mean diameter of HV of 27 patients (77.1%) was 3.61 cm and HV of other 8 patients (22.9%) were too small to show. Number of patients showed waves of borderline, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, varices and ascites was 5 (14.3%), 29 (82.9%), 20 (57.1%), 16 (45.7%), and 6 (17.1%), respectively. Correlated abnormalities included cardiac enlargement 4 cases (11.4%), pericardium thickening 11 cases (31.4%), and pericardial effusion 2 cases (5.7%). Conclusions Stasis cirrhosis mainly demonstrate liver enlargement, inhomogeneous pattern of parenchymal contrast enhancement, contrast medium reflux in IVC and (or) HV, and slight portal hypertension. MSCT and MRI play invaluable roles in diagnosis, differential diagnosis and etiological diagnosis of stasis cirrhosis.

Objective To investigate the imaging features of Budd-Chiari syndrome(BCS) on 64 slice spiral computed tomography(64SCT) and the diagnostic value of 64SCT for BCS.Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography(DSA).Two abdominal radiologists analyzed the CT imaging features of BCS,paying attention to the vascular lesion,the morphology abnormality of the liver and the degree of portal hypertension,with review of DSA findings.Results ①The accuracy of 64SCT for BCS was 93.1%(27/29),and there were 2 false positive cases and no false negative case.The accuracy of 64SCT for those patients with thrombosis of inferior vena cava(IVC) and(or) hepatic vein(HV) was high as compared to those with stenosis of IVC and(or) HV.②The morphology abnormality of the liver included hepatomegaly(24 cases),low attenuation(27 cases) and inhomogeneous pattern of parenchymal contrast enhancement(5 patients in arterial phase and 19 patients in portal vein phase).③The images of all the patients showed the features of portal hypertension.Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom.The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients.For those patients with stenosis of IVC and(or) HV,however,the diagnostic power of 64SCT is limited.

Objective To explore the influence of minimally invasive puncture drainage on blood brain barrier (BBB) function and its mechanism.Methods Ninety-two patients with hypertensive intra-cerebral hemorrhage (HICH) in the Department of Neurosurgery of Jiaxing Affiliated Second Hospital of Zhejiang Province were divided into a control group and an observation group, according to random number table method, 46 cases in each group. In the control group, the conventional craniotomy was performed, while in the observation group, minimally invasive puncture drainage was carried out to remove the hematoma. The National Institute of Health Stroke Scale (NIHSS) were used to evaluate the neural function, the level of serum myelin basic protein (MBP) was detected by enzyme linked immunosorbent assay (ELISA), the central nervous specific serum protein S100 level was measured by electrochemical luminescence method, the albumin levels in serum and cerebrospinal fluid were determined by automatic biological analyzer, and the BBB index was calculated. After 14 days of surgery, the curative effect and incidence of complications of two groups were observed.Results After surgery, the NIHSS scores of two groups were obviously lower than those before surgery, and the degree of descent in observation group was more significant than that in the control group (score: 3.68±2.39 vs. 5.43±3.89,P < 0.05); after surgery, the levels of MBP, S100, albumin in cerebrospinal fluid and BBB in two groups were higher than those before surgery [MBP (μg/L): 3.02±0.28 vs. 3.81±0.29, S100 (μg/L): 0.95±0.24 vs. 1.34±0.27, cerebrospinal fluid albumin (μg/L): 9.89±0.78 vs. 21.43±1.14, BBB index: 0.22±0.04 vs. 0.48±0.05], the differences being statistically significant (allP < 0.05), but the change values in the observation group were less significant than those in the control group. The total effective rate in observation group was significantly higher than that in the control group [84.78% (39/46) vs. 65.22% (30/46),χ2 = 4.696,P = 0.030]. The incidence of wound infection, gastrointestinal bleeding in observation group was markedly lower than that in the control group [16.67% (6/46) vs. 36.96% (17/46), χ2 = 4.120,P = 0.042].Conclusion The minimally invasive puncture drainage has unequivocal clinical curative effect in treatment of patients with HICH, it can protect the nerve and BBB functions and reduce the incidence of complications.

Objective To evaluate the effect of TEG ( thromboelastography ) in the timing choose of CABG( coronary artery bypass grafting ) surgery for patients that receiving DAPT treatment .Methods This study is prospective analysis from November 2013 to May 2014 in Wuhan Asia Heart Hospital.The study cohort consisted of 1 201 patientswith acute coronary syndrome , theage range from 43 to 79 years (61.1 ±10 years) with 134 males and 79 females.and the patients undergo DAPT ( aspirin 100 mg/d, clopidogrel 75 mg/d) which were prepare to the coronary artery bypass grafting and then randomly divided into two groups according to the ratio of 1∶1.There were 101 patients, using perioperative TEG inspection , which conduct the choose of surgery timing according to the ADP-induced platelet-fibrin clot strength ( MAADP) after 24 h of the withdraw of DAPT.Distribute the patients into≥50 mm, 35-50 mm and <35 mm groups according to the MAADPresults, and theirCABG was complete within 1 day, 3-5 days and after 5 days respectively. The other 100 patientsacceptancoronary artery bypass grafting surgery and DAPT patients but without TEG examination as the control group , which were withdrawal the DAPT for 5 -7 days by routine before operation.The primary endpoint is 24 h chest tube drainage andkey secondary endpoint is the total number of transfused red blood cells .Recorded the mean intubation time , ICU stay times , Median length of hospital stayandrethoracotomyrates, 30-day mortality, and 30-day readmission rate at the same time.Using Fisher in the variables , t-test when two groups were compared , use ANCOVA for variable factor correction and Statistical analysis was performed using chi-square test in the calculate of results .Results The average chest drainage in TEG group and the control was 438.8 ml vs 487.8 ml(t=1.063,P=0.289),and the total amount of transfused red blood cell in both groups were 493.8 ml vs 551.6 ml(t=1.228,P=0.2227), there were no significant difference between the two groups .The total waiting time in the three categories of patients in TEG group is 294 days ( an average waiting time of 3.11 days per patient ) and was reduced 38%(3.1 days to 5 days)than the guidelines recommend.Conclusions Although the perioperative bleeding and red blood cell transfusion , the occurrence and postoperative adverse events were similar in two groups , but using thrombelastographto measure platelet function before CABG surgery can help to choose the timing of surgery and reduce the waiting time before surgery .

Background and purpose:Hepatic epithelioid hemangioendothelioma (HEHE) is an extremely rare, vascularly original tumor, and would be misdiagnosed easily in the clinical and imaging characteristics. This study aimed to investigate the imaging features of HEHE and our experience in clinical diagnosis and treatment, and to provide important reference for the diagnosis and treatment of HEHE in the future.Methods:This study retrospectively analyzed clinical manifestations, imaging features, pathological characteristics and treatment effects of 5 HEHE cases confirmed by pathology at Department of Integrative Cancer, Fudan University Shanghai Cancer Center.Results:The ratio of male to female patients was 2 to 3. HEHE predominantly occurred in middle-aged female patients whose ages range from 26 to 65 (mean=45.6). Imaging features of HEHE included multifocal hepatic disease (n=2), systemic multi-center multi-tissue occurrence (n=3). The ultrasound images showed isoechoic or hypoechoic lesions with no obvious blood lfow signal in the lesions. CT plain scan showed isointensity or hypointensity, while MR unenhanced with hypointense T1 signal and hyperintense T2 signal. The density or signal was uneven. Contrast-enhanced CT and MR images showed “slow in slow out”, obvious and variable degrees of peripheral rim enhancement. High FDG uptake showed delayed imaging characteristics (PET/CT). DSA angiography showed the tumor blood vessels were slim. After transcatheter arterial chemoembolization (TACE) surgery, lipiodol deposition within the lesion was not ideal. Under the microscope, tumor cells showed epithelial differentiation; angiogenesis was also visible. Immunohistochemistry staining showed CD31 and CD34 positive in all the 5 cases. Two cases treated with TACE combined with high intensity focused ultrasound (HIFU) and/or radiofrequency ablation (RFA) had good result.Conclusion:The clinical and radio-logical characteristics of HEHE are distinctive. Currently, for patients with systemic multi-organizational multi-center lesions, TACE combined with HIFU and/or RFA might be the most effective treatment method.

Objective To investigate the causes of spinal tuberculosis retreatment and its surgical treatment strategy.Methods Between May 2010 and May 2014,96 patients with spinal tuberculosis who had been operated before were retreated.The dates of them were reviewed.There were 51 males and 45 females with mean age of 39.7 years.Deciding upon the revision surgical procedure should be determined by last operation approach,the direction of compression of spinal cord,the position of sinus and extent of foci.The retreated patients were compared with 481 unretreated patients in the following index including sex,age,duration of disease,focus range,nutrition,drug resistant tuberculosis,debridement,stability of instrumentation,postoperative regular chemotherapy,associated tuberculosis.Results The surgery duration time was 160-280 min,average 210 min,and the blood loss was 400-1500 ml,average 600 ml.The VAS score before the operation was 6-9 (average 7.5) and 1-3 (average 1.5) at the last follow-up,the difference was statistically significant.Neurological deficits in 21 patients clinically improved at least one grade according to the ASIA grading system at last follow-up.Kyphosis and scoliosis degrees were corrected significantly postoperatively and the correction was 9.5°±3.6° at the final follow-up.The average angle loss was 3.5°±1.1°.There was significant difference between the kyphosis angles preoperatively,postoperatively and final follow-up.Kirkaldy-Willis function score showed that the total fine rate was 88％.There were 35 patients whose tuberculosis bacterial culture and drug sensitive experiments suggested drug resistance.Wound healing delayed in 7 patients.24 cases had sinus formation,13 cases in which were healed after wound dressing,and 11 cases undertook operation again.Conclusion The causes of spinal tuberculosis retreatment include uncompleted debridement,drug resistant strains of tuberculosis,irregular postoperative anti-tubercular treatment,poor preoperative nutritional status and failure of spinal stability reconstruction.The key of successful revision surgery includes radical debridement,strut grafting with autologous iliac bone block,proper reconstruction of spinal stability,individualized chemotherapy according to the drug-resistance,and the appropriate use of irrigation and drainage postoperatively.
