BACKGROUND: The pathogenesis of alcoholic avascular necrosis remains unclear. OBJECTIVE: To introduce the physiological structure and pathologic changes induced by alcohol of the microenvironment of femoral head, and to review the research status of the influence of alcohol on the microenvironment of femoral head. METHODS: A computer-based online research of PubMed database for clinical and basic studyies concerning the effect alcohol on the microenvironment of femoral head published from 1990 to 2016. The pathological changes of alcoholic osteonecrosis of the femoral head were overviewed. RESULTS AND CONCLUSION: There are various theories about the pathogenesis of alcoholic osteonecrosis of thefemoral head, but the essence is the disturbance of blood circulation in femoral head, and long-term decrease in the nutrients and oxygen supplying of bone leading to bone degeneration and necrosis. Large-dose intake of alcohol will induce the imbalance of oxidation and anti-oxidation system, which dose harm to the microenvironment of femoral head. The change of oxygen supplying accelerates the necrosis of femoral head, the weakened differentiation of bone marrow mesenchymal stem cells into osteoblasts and the disturbance of bone resorption-formation imbalance finally result in the necrosis and collapse of femoral head. It is expected to provide a new therapeutic strategy for delaying or preventing the early femoral head necrosis by controlling the microenvironment of femoral head.

Objective To investigate the level of spirituality in cancer patients in a 3A grade hospital of Changsha and to analyze the influencing factors. Methods In this study, convenience sampling method was used to select 196 patients with cancer from three hospitals in a 3A grade hospital of Changsha from October 2016 to October 2017. The general situation questionnaire, the functional assessment of chronic illness therapy (FACIT-Sp-12), the social support scale and the post traumatic growth inventory were used to investigate the patient′s spiritual status and to analyze the influencing factors. Results The total spiritual score of cancer patients was 31.09 ± 8.89, the score of meaning dimension was 10.71±2.75, and the peace dimension was 9.84±3.19 and the belief dimension was 10.54± 2.98. The results of multiple regression analysis showed that age, cancer stage, education level, the subjective support of Social Support, relating to others and personal strength of The Posttraumatic Growth were the influencing factors for the spiritual status of cancer patients. Conclusions the spiritual status of cancer patients in a 3A grade hospital of Changsha is at medium level, and the spiritual status is closely related to age, education level, cancer stage, social support and post traumatic growth level. Medical staff should provide spiritual care for patients to improve their psychology and Mental Health and quality of life.
