Primary breast lymphoma is a rare form of extranodal lymphoma with distinct characteristics.It comprises diverse histologic subtypes with diffuse large B-cell lymphoma (DLBCL) as the most common one.In this review,the primary breast DLBCL was focused and the definition,staging,the role of systemic chemotherapy,local adjuvant radiotherapy and rituximab in treatment of primary breast DLBCL were described.

Objective To evaluate clinical risk factors that can predict brain metastasis after complete resection of small cell lung cancer (SCLC) and to assess the role of prophylactic cranial irradiation (PCI) in such kind of patients.Methods Eighty-eight patients with completely resected stage Ⅰ - Ⅲ SCLC from Jan.2000 to Dec.2009 in our hospital were retrospectively analyzed.Kaplan-Meier was used to compare the differences in the incidence of metastasis free survival in different groups.Logistic model was used to assess the independent risk factors for brain metastasis.Results The follow-up rate is 100％,and 37 patients were followed up for more than three years.None of the 3 patients who received PCI developed brain metastasis,while for patients without receiving PCI,24％ developed brain metastases.The incidence of brain metastasis for stage Ⅰ,Ⅱ and Ⅲ SCLC after surgery were 4％,26％ and 29％ ( x2 =7.57,P =0.023),respectively.The median survival time and the 3-year survival rate were 18 months and 25％ for patients who developed brain metastasis,and 48 months and 59％ for those without brain metastasis ( x2 =10.63,P =0.001 ).Both univariate and multivariate analyses showed that pre-treatment disease stage wasindependent risk factor for brain metastasis ( x2 =7.57,8.52 ; P =0.023,0.004 ).Age,sex,tumor location,pathological type,induction chemotherapy,and postoperative chemotherapy/radiotherapy were not significantly correlated with the incidence of brain metastasis ( x2 =0.03,0.00,0.00,2.58,0.01,1.23,0.84;P =0.869,0.998,0.992,0.109,0.936,0.266,0.361,respectively).Conclusions Pre-treatment disease stage was independent risk factor for brain metastasis in SCLC.PCI may be important for stage Ⅱ -Ⅲ SCLC but not for stage Ⅰ disease.<英文关键词>=Carcinoma,small cell lung/surgery; Neoplasm metastasis,brain/prophylactic irradiation; Factors analysis

Objective To investigate the prognostic factors and the clinical outcome of locally recurrent rectal cancer after radical resection. Methods From April 2000 to April 2004, 105 patients with locally recurrent rectal cancer after radical resection were re-treated in Tianjin cancer hospital. Thirty-four patients were re-treated with surgery combined with adjuvant chemoradiotherapy (group 1), 35 with surgery alone (group 2), and 36 with chemoradiotherapy (group 3). The impact of 17 clinicopathological factors and treatment modalities on the survival was analyzed. Results The follow-up rate was 95. 2%. The median survival time was 23 months. The 1-, 3-and 5-year survival rates of patients with locally recurrent rectal cancer were 63% ,34% and 19%, respectively. The 1-, 3-and 5-year survival rates were 79%, 55% and 32% in group 1 ; 68%, 40% and 14% in group 2; and 64%, 36% and 11% in group 3; respectively (χ~2 =7. 96,P =0. 019). The univariate analysis showed that the degree of differentiation, depth of tumor invasion, number of metastatic lymph nodes, initial TNM stage, recurrent location, time to recurrence, and surgery combined with adjuvant therapy were significant prognostic factors, with the last 4 being the independent prognostic factors. Conclusions Surgery combined with chemoradiotherapy may improve the survival of patients with locally recurrent rectal cancer.

Major depressive disorder (MDD) is a common affective disorder.With its unique characteristics and advantages,traditional Chinese medicine (TCM) has played an important role in the treatment of MDD.Recent researches have revealed that the neuroinflammation-induced neurogenesis reduction were the key pathology of MDD.This analysis indicated that salvia was frequently used for treatment of MDD from the prescriptions reported in literatures.Salvianolic acid (SalB),one of main active compounds of salvia,had showed anti-inflammation and neuroprotection effects in previous studies.In this review,we summarized the antidepressant effects of SalB through regulating microglial activation,inhibiting neuroinflammation and promoting neurogenesis.According to the theory of removing blood stasis for promoting tissue regeneration,it was suggested that the novel antidepressant strategies for antiinflammatory and neuroprotective activities were through microglia-modulating pathway with TCM.
