[Objective] Expressions of human epidermal growth factor receptor 2(HER-2),p53,estrogen receptor (ER),and progesterone receptor (PR) in tissues of breast invasive ductal carcinoma are not only applied to determine the therapeutic regimen,but they may also be related to the prognosis.We investigated the levels of these proteins among different clinical stages and the correlations.[Method] One hundred and thirty-eight tissues from cases with breast invasive ductal carcinoma were tested with immunohistochemistry.New scoring standards and rank test were applied.The indices were digitalized and semi-quantified.[Results] In the tissues from high clinical stage,the expression of HER2 was significantly increased,while expression of PR was markedly decreased.[Conclusion] Expression of HER2 and PR might be better markers for predicting clinical stages and prognosis.

OBJECTIVETo investigate the contents of 16 basic amino acid and find out the variation of them in Dendrobium officinale with different germplasms and physiological ages, and then provide scientific basis for the quality evaluation and the breeding of D. officinale.

METHODThirty-three samples with 1-3 ages were collected from cultivated fields of Zhejiang. The samples were acid hydrolyzed, and then 16 basic amino acid contents of samples were determined by amino acid analyzer.

RESULTThe average contents of 7 necessary amino acid were in 0.28 - 2.96 mg x g(-1), the average contents of other 9 basic amino acid were in 0.53 - 4.20 mg x g(-1). The contents of many amino acids were impacted by germplasms significantly, and contents of several amino acids were impacted by physiological ages significantly.

CONCLUSIONThere were rich basic amino acids in D. officinale. The breeding of D. officinale can increase the contents of essential amino acids and other basic amino acids. The relations among physiological age and amino acid contents were as follows: three years > two years > one year. The contents of Asp and Tyr have significantly negative correlation with magnesium, the content of Pro has significantly positive correlation with copper.

PURPOSE: To evaluate the prognosis of nasopharyngeal carcinoma (NPC) patients who developed bone-only metastasis after primary treatment and the stratification of these patients into different risk groups based on independent prognostic factors. MATERIALS AND METHODS: Eighty NPC patients who developed bone-only metastasis after definitive radiotherapy from October 2005 to December 2010 were enrolled. All these patients received palliative treatment for bone metastasis, including chemotherapy and/or radiotherapy. Clinical features, treatment modality, and laboratory parameters were examined with univariate and multivariate analyses. RESULTS: The median follow-up time was 15.5 months (range, 2-67 months) for the whole cohort. The median overall metastatic survival (OMS) time and the 2-year estimate OMS rate were 26.5 months and 52%, respectively. Multivariate analysis indicated that patients with short metastases-free interval, multiple bone metastases sites, high serum lactic dehydrogenase levels, and treated with radiotherapy or chemotherapy alone had significantly worse outcomes. Patients were stratified into three different risk groups based on the number of adverse factors present. The OMS curves of the three groups were all significantly different (p<0.001). CONCLUSION: Severl prognostic factors were found to be associated with worse outcomes. According to the number of adverse factors present, bone-only metastasis patients can be stratified into three risk groups with significantly different prognoses. Such grouping may help in improving the design of clinical trials and in guiding individualized treatment for NPC patients with bone-only metastasis.
