Autologous stem cell transplant (ASCT) is a potentially curative therapy for patients with relapsed and refractory or aggressive non Hodgkin ' s lymphoma, relapse is still common and is caused by high levels of tumour cell burden in the host and contamination of the stem cells with tumour cell. To improve effect of ASCT, ① in vivo puring with riluximab in pre transplant, depletion of B cells from the peripheral blood and clear the contamination of the malignant cells; ②the combination chemotherapy replace with rilumixab and non cross resistance drug in post transplant, killing tumour cells in the host; (3)involved field radiation therapy(IFRT) as a adjunct to pre or post transplant, reducing the relapse rate.

B-cell lymphomas(BCL) are the most frequent types of lymphoma and encompasses different entites with variable clinical behavior and diverse molecular features. In general terms, it can be subdivided into 2 main groups, low- and high-growth fraction lymphomas. In low-growth fraction lymphomas, cell accumulation can be achieved through the inhibition of apoptosis without a very severe deregulation of cell proliferation. In contrast, high-growth fraction BCL are characterized by an enhanced proliferative activity, as a result of the deregulation of oncogenes with cell cycle regulatory functions, such as Bcl 6 and c-myc. A fraction of both low- and high-growth lymphomas acquire additional alterations in cell cycle control, usually involving cyclin-dependent kinase inhibitors and evolve to highly aggressive tumors.

Objective To study the effect of continuous venovenous haemodiafiltration (CVVHDF) on the clearances of various solutes in multiple organ dysfunction syndrome (MODS)dogs.Methods Dogs were subjected to hemorrhagic shock plus resuscitation and endotoxemia to set up MODS model,then they were randomly divided into 2 groups: MODS group (M group)and MODS+CVVHDF group (M+C group).A PRISMA pre-dilution system with AN-69 filter was applied.Solute clearance of nitric oxide(NO),urea nitrogen(UN),creatinine (Cr),interleukin-6 (IL-6),interleukin-10 (IL-10),tumor necrosis factor-α (TNF-α) and endotoxin (LP) was determined with same dialysate and ultrafiltrate volume during CVVHDF.The clearance of various solutes (Kd) was calculated by the concentration of the cleared solutes in effluents (E) based on the formula Kd=(ExQE)/P.Results Clearances of NO,UN,Cr were greater than those of IL-6,IL-10,TNF-α,LP during the treatment of CVVHDF.Conclusion CVVHDF could effectively reduce the levels of various solutes in the development of MODS by convection and absorption.

Objective To evaluate the efficacy of emergency transcatheter arterial embolization(TAE)for spontaneous rupture of hepatocellular carcinoma(HCC).Methods We retrospectively reviewed 16 cases of spontaneous ruptured HCC which had been treated in our hospital between 1997 and 2005.Emergency TAE was performed in the 16 patients,with 6 cases complicated by hypovolemic.Results Bleeding from the ruptured HCC was stopped at the end of the procedure in 16 patients who had undergone successful embolization.The time from the onset of clinical symprtom to TAE been completed was 1.5-5 hours(mean,3.6 hours),The shortest time was 1.5 hours in 3 patients.Following the achievement of hemostasis by TAE,transcatheter arterial chemoembolization(TACE)2-6 times for each case with average 3.7 and CT guided percutaneous ethanol injection(CT-PEI)5-9 times for every case with arerage 6.8 were performed in 12 cases.3 cases were given up for further treatment.The liver transplantation was carried out in 1 case 3 days after TAE.The average survival time was 14.3 months.Conclusions Emergency TAE is safe and effective for bleeding due to spontaneous rupture in HCC and would achieve better result by adding TACE and CT-PEI.Liver transplantation is one of the options for the patients with poor liver function.The combination of all methods above can prolong patients survival time.(J Intervent Radiol,2006,15:228-231)

Objective To assess CT, MR manifestations and diagnostic value in hepatic tuberculosis. Methods CT findings in 12 cases and MR findings in 4 cases with hepatic tuberculosis proved by surgery or biopsy were retrospectively analyzed. Results (1) CT findings: one case of serohepatic type of hepatic tuberculosis was multiple nodular lesions in the subcapsule of liver. Parenchymal type were in 10 cases, including multiple,miliary, micronodular and low density lesions with miliary calcifications in 2 cases, singular, low density mass with multiple flecked calcifications in 3 cases, multiple cystic lesions in 1 case, multiple micronodular and low density lesions fusing into multiloculated cystic mass or “cluster” sign in 3 cases, and singular, macronodular and low density lesion with multiple miliary calcifications in 1 case. One case of tuberculous cholangitis showed marked dilated intrahepatic duct with multiple flecked calcifications in the porta hepatis. (2) MR findings in 4 cases were hypointense on both T 1WI and T 2WI in one case, hypointense on T 1WI and hyperintense on T 2WI in 3 cases. Enhanced MR in 3 cases showed slightly peripheral enhancement or with multilocular enhancement. Conclusions Various types of hepatic tuberculosis had their different imaging findings. The typical CT and MR findings could suggest the diagnosis.

Objective To summarize the application of ruyi jinhuang powder dissolved in ethanol in the treatment of chemotherapeutic phlebitis induced by indwelling needle. Methods 88 cases of patients with chemotherapeutic phlebitis were randomly divided into the observation group and the control group with 44 cases in each group.
