1.Recent progress in molecular pathogenesis of B-cell lymphoma
Journal of Medical Postgraduates 2004;0(02):-
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.

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.

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 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 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. The observation group was given wet compress using ruyi jinhuang powder dissolved in ethanol, while the control group used hot towels of 40 to 50℃. The treatment effect was compared between the two groups. Results The treatment effect of the observation group was better than that of the control group. Conclusions Treatment of chemotherapeutic phlebitis using wet compress with tracditional Chinese medicine showed significant effect, which is an effective method in the treatment of chemotherapeutic phlebitis induced by indwelling needle.

Objective:To investigate the status quo and influencing factors of tutors' guidance satisfaction of medical postgraduates.Methods:Te satisfaction of tutors' guidance of 149 medical postgraduates from a class Ⅲ teaching hospital in Beijing who would graduate were investigated with questionnaires and statistically analyzed. SPSS 22.0 software was used for data statistical.Results:The rate of satisfaction of tutors' guidance was 92.62%. The satisfaction with the training of ideological ethics and academic integrity was relatively higher (94.97%), and the satisfaction with career planning guidance was lower (89.71%). The tutors' guiding frequency and contents, tutor's attention to postgraduates and the relationship between them, and so on had certain influence on the tutors' guidance satisfaction.Conclusion:The mechanism of tutor management should be strengthened and the management level of postgraduate should be improved.

Objective Aortic dissection is accute in occurrence along with fast change , which is inclined to to induce psy-chotic symptoms and affect the lives of patients .The study was to investigate the effects of healthcare cooperative intervention on pa-tients with psychiatric symptoms secondary to aortic dissection . Methods We established medical cooperation organization structure to clarify the division of responsibility along with a quick assessment form , a process chart and a green channel for emergencey treat-ment.The above method was applied to intervene 32 patients with psychiatric symptoms secondary to aortic dissection and observe the diagnosis time , the time from diagnosis to surgery , the remission time of psychiatric symptoms , the incidence of adverse events and the length of stay. Results 32 patients were diagnosed within 30min followed by emergency surgery within 30min after diagnosis, which was 1-2 hours shorter than the previous diagnosis and surgery preparation time .5-21 d after surgery , psychiatric symptoms have been effectively controlled.Extubation, falling out of bed, self-injury or injury and other adverse events did not occur .No patient died, and the average length of stay was 13.5d, which was 1.75d shorter than the length of stay of previous similar patients . Conclusion The healthcare cooperation method can quickly identify patients with psychiatric symptoms secondary to aortic dissection , prevent adverse events and shorten the length of stay .
