Objective To investigate the clinical significance of detecting mammaglobin in sentinel lymph nodes(SLN) of breast cancer. Methods In 32 breast cancer patients, methylene blue was injected around parechyma of breast cancer to locate the SLNs, and nested RT PCR(reverse transcriptase polgmecane chain reaction) was used to examine the expression of mammaglobin mRNA. Results The SLN was successfully identified in 30 of the 32 cases(93.8%).The micrometastases detection between group SLNs and non SLNs had significant statistical difference(P

Objective To improve the method of orthotopic liver transplantation model in mice.Methods On the basis of "Qian SG" mothod,the techniques of perfusion,harvesting,and trimming of donor's liver,as well as the anastomosis of superior and inferior caval veins were improved.Operations were performed in 70 mice with improved technique(experiment group) and in 70 mice with conventional technique(control group),respectively.The operation time in both donors and recipients,and the survival rates of 48h,1 week and 1 month after operation were compared between the two groups.Results The operation time for both donors and recipients and the time of anhepatic phase were 37?2min,45?2min and 16?2min,respectively in experiment group,while they were 45?2min,54?2min and 23?2min,respectively,in control group,so that the average time for each procedure was significantly shorter(P0.05).Conclusions The improved technique may shorten the operation time and raise the survival rate,and is an ideal method for the establishment of orthotopic liver transplantation model in mice.

Objective: To investigate the clinical characteristics, diagnosis, treatment and prognosis of discordant lymphoma. Methods: The clinical data of one patient with discordant lymphoma at the PLA Strategic Support Force Characteristic Medical Center were retrospectively analyzed, and the related literatures were reviewed. Results: The patient was treated for thrombocytopenia and the examination showed splenomegaly. After hormone treatment, the platelet rebounded and thrombocytopenia occurred during hormone reduction. Splenectomy was performed. Postoperative pathological diagnosis of splenic marginal lymphoma was made and observed. Axillary lymph node enlargement occurred nine months later. Pathological diagnosis of diffuse large B-cell lymphoma was made by using lymph node biopsy, and the disease condition was alleviated after immunotherapy combined with chemotherapy. Conclusions Discordant lymphoma is rare and shows no special clinical manifestations. Its diagnosis should rely on pathological examination. Immunotherapy combined with chemotherapy may be more effective.
