Objective To assess the characteristics of magnetic resonance imaging (MRI) for spinal cavernous angiomas.Methods The examinations of plain scan and contrast enhanced scan of magnetic resonance (MR) were performed in three patients with spinal cavernous angiomas.Results The focus of two cases was located in thorax segment of the spinal cord and one in lower cervical segment.All focuses were single and the shape of spinal cord was normal or slightly thick. MRI characteristic of spinal cavernous angiomas was just like popcorn or mulberry with a jumbled gobbet signal. Low and short T2 signal appeared around the focus. In all cases, there were no obvious contrast enhanced signal in 2 cases and one case with moderate contrast enhanced signal. The diameter of hemorrhage was smaller than that of the spinal cord.Conclusion MRI has higher sensitivity and specificity in the diagnosis of spinal cavernous angioma.

Objective To investigate the efficacy of liver transplantation for the treatment of polycystic liver disease.Methods The clinical data of 8 patients with polycystic liver disease who received liver transplantation at the Third Affiliated Hospital from September 2003 to July 2009 were retrospectively analyzed.All patients underwent modified piggyback liver transplantation with vena cava plasty,and 1 of the patients received simultaneons liver-kidney transplantation.Data including acute rejections,complications,graft functions and survival time of patients were recorded.Results Operation was successfully performed on all patients.The mean operation time,anhepatic phase and operative blood loss were (7.5 +2.8)hours (range,4-11 hours),(42 + 14)minutes (range,25-70 minutes) and (2250 ± 1850)ml (range,2000-6500 ml),respectively.One patient received liver retransplantation at 45 days after primary liver transplantation because of hepatic artery stenosis.Two patients died during perioperative period.One patient died of pulmonary infection and multiple organ disfunction syndrome (MODS) at 39 days after operation,and the other one died of MODS at 59 days after operation.The median follow-up time was 60 months (range,37-93 months).Six patients survived for more than 3 years,4 patients survived for more than 5 years and 2 patients survived for more than 7 years.No acute rejection of gratis was observed at the end of the follow up.Conclusion Liver transplantation is safe and effective for the treatment of polycystic liver disease.

0bjective To study the potency of Entecavir Maleate(ETVM),Entecavir(ETV) and Adefovir(ADV) on suppressing duck hepatitis B virus (DHBV) replication.Methods DHBV DNA positive ducks were used as experimental animal model.Ail these ducks were randomized to different arms and respectively given high,medium and low dosage of ETVM,ETV and ADV.ETVM and ETV were given orally daily respectively for six weeks and ADV orally 3 times every week for six weeks.The serum DHBV DNA levels were tested every 2 weeks at day 0 and,after that,at week 2,4.6 and 8 respectively by real-time fluorescent quantitative polymerase chain reaction(PCR).The results were analyzed by paired-samples t test.Results The treatment resulted in the reduction of viral load among all ETVM.ETV or ADV treated groups.The viral load of DHBV DNA at pretreatment and week 6 in the ETVM high dosage group were(7.34±1.33)and(2.12±2.50)lg copy/mL,respectively(P

Objective:To observe the effect of intra-bone marrow injection (IBMI) of fetal liver mononuclear cell suspension on reconstructing the hematopoietic system in mice. Methods : The fetal liver mononuclear cells from the mice with gestational age of 13.5 days were obtained by Ficoll separation technique, and then the hematopoietic stem cells (HSCs) were obtained by magnetic bead sorting. The fetal liver mononuclear cells were injected into the tibias of 137Cs irradiated mice by IBMI. The recipient mice were observed for reconstitution of the hematopoietic system by routine blood examination, blood smear and bone marrow smear. The donor HSCs in the bone marrow of the recipient mice was subjected to flow cytometry 1 year after transplantation. Results: HSCs accounted for 0.171% in the mouse fetal liver mononuclear cells. One week after transplantation of mouse fetal liver mononuclear cells, blood cells derived from donor cells were detected from peripheral blood; in the third week after transplantation, peripheral blood leukocytes, red blood cells and hemoglobin of recipient mice were restored to the pre-irradiation levels; the percentage of donor-derived blood cells in peripheral blood in the fifth week was stable; the HSCs in the bone marrow of recipient mice were derived from donor cells 1 year after transplantation. Conclusion: The murine fetal liver mononuclear cells can efficiently reconstruct the hematopoietic system of mice by IBMI.

Objective • To explore the incidence and analyze the risk factors of acute lower deep venous thrombosis (ALDVT) in multiple injury patients. Methods • A total of 175 multiple injury patients in trauma emergency center of The Sixth People's Hospital, Shanghai Jiao Tong University, from Jan. to Jun. in 2017 were chosen, and their clinical data were collected. The ALDVT group and the non-ALDVT group were differentiated according to the results of ultrasound, and the incidence of ALDVT was calculated. Univariate analysis and multivariate Logistic regression analysis were used to investigate the correlations between the occurrance of ALDVT and the factors, including demographic characteristics, vital signs and hematological parameters. Results • Fifty-six patients (32%) developed ALDVT in 175 multiple injury patients. Univariate analysis showed that there were statistically significant differences in the numbers of multiple injury patients with upper limb fracture, lower limb fracture, spinal injury, pelvic fracture, chest and abdomen injury, higher injury severity score (ISS) (≥ 25 scores), or higher glucose (≥ 10 mmol/L) between two groups (all P<0.05). In the coagulation parameters, compared with the non-ALDVT group, the levels of D-dimer and fibrinogen degradation products in the ALDVT group were significantly elevated (both P=0.001). Multivariate Logistic regression analysis showed that the level of glucose (≥ 10 mmol/L) (P=0.009), ISS (≥ 25 scores) (P=0.024), multiple injury with spinal injury (P=0.048), and multiple injury with pelvic fracture (P=0.029) were the independent risk factors of the ALDVT patients. Conclusion • There is a high occurrence of ALDVT in multiple injury patients. The level of glucose, ISS, multiple injury with spinal injury, and multiple injury with pelvic fracture have important predictive significance for the diagnosis of ALDVT.

Objective To report clinical study of diabetic foot with microsurgical treatment.Methods 32 cases basing on physical treatment underwent operation which included reconstruction of vessel under DSA and flap transfer and relaxation of nerves.Results 8 eases were examined with DSA after operation,it showed that the bypass grafts were unobstructed and the distal blood were improved;All flap were lively. Conclusion The ulcer of the patients with diabetic foot was closed early and the blood supply of the limb have been reconstructed by microsurgical treatment,it can not only avoid amputation or lower the limb amputation level,but also improve the life quality of patients and obtain social benefit.
