Objective:To learn the depression status of the hospitalized pregnant women in labor and its related influencing factors,and to provide the theoretical basis for exploring depression intervention of the pregnant women in labor.Methods:Self-Rating Depression Scale was used for investigating the depression status of 203 hospitalized pregnant women in labor who were in hospital from November 2014 to May 2015,and the impacts of demographic characteristics,maternal history and physical condition and health care on depression status of hospitalized pregnant women in labor before pregnancy and during pregnancy were analyzed using Logistic regression.Results:Fifty-three people with depressive tendencies were detected among pregnant women in labor,and the positive rate was 26.1％.The differences in positive rates of depression tendency of the pregnant women between less than 30 years,30-39 years and 40 years and above had no statistical significance (P＞0.05).Univariate Logistic analysis showed that the differences of occupation,overweight or obesity,low-dose folic acid supplements before pregnancy were statistically significant (P＜0.01).Multivariate Logistic regression analysis showed that risk factor for pregnant women was overweight or obesity pre-pregnancy,and the risk was 2.335 times to non-overweight or non-obesity pregnancy women (OR=2.335,95％CI:1.101-4.954,P＜0.05).Conclusion:The pregnant women have the depression tendency,especially the pregnant women with high body mass index before pregnancy.The knowledge of psychological health education should be provided for them.

Professor Cai Wanru believes that in the stable phase of chronic obstructive pulmonary disease, "phlegm" and "stasis" are intertwined, with "phlegm" as the main component. Disease is manifested mostly in the lungs, spleen and kidney, and along with the duration of the disease, the patients are prone to "sputum", "stasis" and other pathological products, so that acute aggravating symptoms are often induced due to the transformation from "phlegm" to "stasis". The clinical manifestations are mainly the lack of righteousness, and various symptoms due to phlegm stagnation and blood stasis. Therefore, Professor Cai believes that the thought of "preventive treatment of disease" should be throughout the treatment of the disease. The thought is based on the principle of the relationships between the five internal organs. According to the characteristics of disease transmission, combined with the syndrome differentiation of physical constitution, the importance of strengthening the body resistance and nourishing the vigour was emphasized. In terms of the methods of treatment, methods such as nourishing the lungs and tonifying the spleen, warming the kidney and tonifying qi are often applied, so the prescription is flexible and the compatibility is rigorous. In terms of the control of symptoms and prevention of acute exacerbations, it has a significant effect. Therefore, the thought of "preventive treatment of disease" proposed by Professor Cai Wanru has a practical value in the clinical treatment of chronic obstructive pulmonary disease, which is worthy of promotion.
