According to these situations and problems,this paper analyzes difficulties in long-term care of rural disabled elderly. From the perspective of welfare pluralism,it comes up with development paths for long-term care of rural disabled elderly with joint participation of government,communities,non-profit organizations on the basis of the family endowment.展开更多

Methods： The clinical data of 206 advanced NSCLC patients who were treated with CM and Western medicine in Beijing Cancer Hospital from April 1999 to July 2013 were retrospectively analyzed. Long-term survivors were defined as OS ≥ 3 years after treatment with CM and chemotherapy. Twenty-eight patients had OS ≥ 3 years, 178 had OS 〈 3 years, and all clinical data were statistically analyzed with the Cox model. Variables were gender, age, smoking status, performance status （PS） score, pathological type, clinical stage, first-line chemotherapy, targeted therapy, and use of CM. Univariate survival analysis was performed using the Kaplan-Meier method and log-rank sequential inspection. Multivariate survival analysis was used to analyze the meaningful factors of univariate survival analysis with the Cox model. Results： The survival rate of patients with OS ≥ 3 years was 13.6% （28/206）. Cox multivariate regression analysis showed that PS score, clinical stage, disease control rate to first-line chemotherapy, and use of CM were independent factors of long- term OS （all P〈0.05）. However, gender, age, smoking, and use of epidermal growth factor receptor tyrosine- kinase inhibitor were not significant （P〉0.05）. Conclusion： PS score, clinical stage, disease control rate to first- line chemotherapy, and use of CM are probably independent prognostic factors for long-term OS in patients with advanced NSCLC.展开更多
