This paper mainly discussed the present situation of the pension mode transformation from traditional family pension to social pension. The existing ethical issues in pension institution include: old filial piety thought deeply rooted;institutional care services cannot be carried out caused by unfair distribution balance; humanistic thought of human ethical care implementation does not do well; some agencies have occasional bad behavior. Therefore, this paper proposed some advices based bioethical perspective:for old people and their children, advo-cate the new filial piety;pension institutions not only improving the quality of the hardware but also should strength-en humanistic ethics concern;establish and perfect the laws and regulations, combining the rule of law with moral and ethical;the relevant government departments should insist on and strengthen the principle of fair justice.

In recent years , with the development of medical health and the progress of economy , the citizens'demands for daily health are improved continually , and health services need to be rapid development .However , in the principle of medical ethics and humanism humanistic care of patients , it is easy to ignore the other two key as-pects -the medical staff and patients with the family .This paper analyzed the emotion and psychology of patients'families and medical staff in caring for the patients and corresponding solutions , so that the three can effective communication to build a harmonious doctor -patient relationship , and then promote patient recovery and be advan-tageous to the long-term development of the reform of health services .

Objective:To investigate the pathological changes of JNET classification of colorectal tumors.Methods:Data of patients with colorectal neoplasms who underwent narrow-band imaging combined with magnifying endoscopy, and whose postoperative pathological specimens were obtained at the endoscopy center of the Affiliated Hospital of Guizhou Medical University from January 2015 to June 2018 were analyzed retrospectively. The endoscopic JNET diagnosis and pathological features (surface pit epithelial exfoliation, surface mucosal necrosis structure, surface mucosal ethmoid reticular structure, fibrous tissue reactive hyperplasia, mucosa muscle without residual and carcinomatous interstitial reaction) were analyzed.Results:A total of 81 patients with colorectal neoplasms (diameter >1.5 cm) were enrolled with 74 cases receiving endoscopic treatment and seven cases receiving surgical treatment. The frequency of surface mucosal sieve reticular structure in type 3 of JNET (20.00%) was lower than that in type 2B (42.86%), which was in turn higher than that in type 2A (2.78%), with significant differences ( P<0.05). The frequencies of fibrous tissue reactive proliferation, no residual mucosal muscles, and carcinomatous interstitial reaction in type 2A and 2B were lower than that of type 3, with significant differences (all P<0.05). There were significant differences in the consistency group and inconsistency group of JNET classification and pathological diagnosis in surface pit epithelial exfoliation and surface mucosal necrosis (all P<0.05). Conclusion:Type 2B of JNET classification indicates that the pathological features may be the surface mucosal reticular structure; type 3 indicates reactive hyperplasia of fibrous tissue, no residual mucosal muscles and cancerous interstitial reaction. The exfoliation of the surface pit epithelium and the necrosis of the surface mucosa may be the pathological interference factors affecting the accuracy of JNET classification diagnosis.
