Objective:To analyze the diagnosis and treatment of 1 case of primary bone marrow diffuse large B cell lymphoma (DLBCL),and to provide the reference for its dignosis and treatment. Methods:Combined the medical history and other auxiliary examination results, the possibility of diagnosis of primary bone marrow lymphoma (PBML)was suspected. Bone marrow biopsy and immunohistochemistry were carried out for diagnosis, and R-CHOP (rituximab, cyclophosphamide,doxorubicin,vincristine,and prednisolone) was selected as the chemotherapy scheme. Results:The diagnostic basis of the case was in accordance with the diagnostic standard of PBML.According to the results of immunohistochemical staining,it was classified as the DLBCL subtype. Then the patient received 6 cycles of R-CHOP immune chemotherapy. Complete remission of bone marrow cell morphology was gained after the first cycle of R-CHOP treatment,and the patient was treated for another five cycles and the complete remission was retained in 3 months of follow up after drug withdrawal. Conclusion:Bone marrow biospy and immunohistochemistry have the unique diagnostic values for primary bone marrow DLBCL,and the regimens containing rituximab may provide a ideal efficacy during short term observation.

Objective To observe and compare the antiemetic effectiveness and adverse effects of magnetotherapy plus the 5 -hydroxytryptamine (5-HT3 ) receptor inhibitor granisetron hydrochloride with that of granisetron hydrochloride alone with chemotherapy patients. Methods Sixty-four patients were randomized to receive either granisetron hydrochloride alone ( control group: granisetron hydrochloride 3 mg intravenous infusion before chemotherapy, from the 1st day of chemotherapy until the day after the chemotherapy course was completed) or magnetotherapy plus granisetron hydrochloride ( treatment group: the same granisetron hydrochloride regimen plus rotatory magnetotherapy of 1 h/time every day after chemotherapy). The baseline characteristics of the two groups were similar. The patients' emesia was evaluated according to the WHO's criteria. The density of 5-HT, in serum was detected by enzyme-linked immunosorbent assay ( ELISA). Results In terms of acute vomiting, there was no significant difference between the two groups, but in terms of tardive vomiting, the effectiveness in the treatment group was significantly better than in the control group. The densities of S-HT, in serum in the treatment and the control group were (225.32±57.29 ) ng/ml vs (213.00±53.29 ) ng/ml before chemotherapy and (273.88±5.42) ng/ml vs ( 313.17±76.36 ) ng/ml after chemotherapy, a significant difference. The rates of adverse events were 36.36% and 48.39% respectively in the treatment group and control group, a difference which was not significant. Conclusions Magnetotherapy plus granisetron hydrochloride is more effective than granisetron hydrochloride alone, and the two therapies have a synergistic effect. Adverse events didn't rise in the treatment group.

Objective To determine the main CT features and the key points of differential diagnosis of multilocular cystic renal cell carcinoma (MCRCC) classified according to 2004 WHO pathological diagnostic criteria. Methods According to the criteria, 40 patients were divided into two groups: MCRCC group and other subtypes of cystic renal cell carcinoma (CRCC). The CT findings were evaluated and compared between two groups for cystic content, wall, septum, nodularity, calcification and enhancement. ROC curve was used to determine the cut-off value of the possible CT feature which could distinguish MCRCC from other subtypes of CRCC. Results Seventeen cases of MCRCC group and 23 cases of CRCC group were included in this study according to the diagnostic criteria. MCRCC appeared as a well defined multilocular cystic mass with thin wall and sepia and no expansile solid nodules. Thickness of cystic wall and/or septum is was main CT findings to distinguish MCRCC from other subtypes of CRCC (P ＜ 0.01 ). The cut-off value of the thickness was 6 mm and its sensibility, specificity was 89% ,75% respectively. Conclusion Cystic wall and/or septum with a thickness of less than 6 mm are the main CT findings to dis tinguish MCRCC from other subtypes of CRCC.
