Objective: To investigate estrogen receptor (ER) and progesterone receptor (PR) in the tumor derived from non-target organ (primary bronchogenic carcinoma), and correlation with the tumor. Methods: According to WHO histo-logical classification of lung tumors, 146 resected specimens of lung canrer were examined microscopically; ER and PR were detected on paraffin-embedded tissue sections using immunohistochemical staining. Results: 58.9% of the cases were positive for ER, 69. 1 % for PR,and 46.6% positive for both. There was a significant correlation between ER and PR positive percentage and degrees of histological differentiation in lung cancer, while ER and PR percentage appears to have no relationship with histological type, tumor size, age and sex of the patients. Conclusion: It is demonstrated that ER and PR are present in non-small cell lung cancer. These observation may provide a basis for adjuvant hormonal therapy in selected lung cancer patients.

Purposes　To observe the clinicopathologic and immunohistochemical features of primary lymphoma of bone(PLB). Methods　Eight cases of PLB were investigated by light microscopy and immunohistochemical staining. Results　The mean age of eight cases of PLB was 51 years. Radiographs of all cases showed the lytic lesions or osteoporosises; All the cases were diffuse non-Hodgkins lymphomas(NHL), including 4 large cell lymphomas (centroblastic, CB), 2 centrocytic(CC), one mixed cell (CB-CC ) and one lymphoplasmacytic (LP); Immunohistochemical features revealed 6 cases of B-cell, 2 T-cell. Conclusions　The peak incidence for PLB is in the 5th decade with the radiologic appearance of lytic lesions or osteoporosises. All tumors are the diffuse NHL, including mainly large cell lymphomas and immunophenotypic features of B-cell lymphomas. Immunohistochemistry is helpful in the differential diagnosis of PLB.

Objective To explore the effect of living mode on quality of life and life satisfaction of patients with spinal cord injury who survived Tangshan earthquake. Methods From February to May, 2016, 76 patients with spinal cord injury survived the earthquake were in-vestigated, among whom 38 patients lived in the nursing home or rehabilitation village and the other 38 patients discretely lived at home. Their quality of life and life satisfaction were assessed with WHO Quality of Life-BREF (WHOQOL-BREF) and Life Satisfaction Assess-ment respectively. Results The scores of physical, psychological, social adaptation and environment field in WHOQOL-BREF were signifi-cantly higher in the concentrated living group than in the scattered living group (t>8.97, P<0.001), as well as the life satisfaction (t=6.55, P<0.001). Conclusion The concentrated living mode could improve the quality of life and life satisfaction of the patients with spinal cord inju-ry survived Tangshan earthquake.

Objective To survey the survival status, functional status, marital status and the present situation of the survival patients with spinal cord injury 40 years after Tangshan earthquake. Methods From February to May, 2016, a total of 216 patients with spinal cord injury were surveyed with questionnaire, in which 139 cases lived centralized and 77 cases lived scattered. The questionnaire was self-designed and included eleven items and 51 questions, which related to ability of daily life, marital status, employment status and socioeconomic status and so on. Results A total of 960 (25.15%) patients with spinal cord injury survived 40 years after Tangshan earthquake. In 216 surveyed pa-tients, the employment rate was 9.3%, the married rate was 53.2%, and 44.9%earned less than 500 yuan every month. The incidence was 25.9%for pressure score, 50.50%for neuralgia (severe pain accounted for 23.51%), and 19.40%for urinary tract stones. 56%of patients could take their own basic self-care. Conclusion There were many problems such as high complication rate, low employment rate and poor economic condition in the spinal cord injury group 40 years after Tangshan earthquake.
