Objective To explore the clinical value of combined detection of human epididymis protein 4(HE4) ,carbohydrate an‐tigen 199(CA199) and carbohydrate antigen 125(CA125) in diagnosis of ovarian cancer and benign ovarian cysts .Methods The se‐rum levels of HE4 ,CA125 and CA199 were determined by using chemiluminescent immunoassay in 45 cases of patients with ovarian cancer(ovarian cancer group) ,60 cases of patients with benign ovarian cyst(benign disease group) ,and 30 cases of healthy individu‐al(control group) .Results The serum levels of HE4 ,CA199 and CA125 in the ovarian cancer group were higher than those in the ovarian cancer group and control group ,there were statistically significant differences(P<0 .05) .Compared with the control group , the serum level of CA125 in benign disease group was significantly higher(P<0 .05) ,while no statistically significant differences of serum levels of HE4 and CA199 were observed between the two groups(P>0 .05) .The sensitivity of combined detection of the three indicators increased to 82 .2% ,and the specificity remained at 90 .0% .Conclusion Combined detection of HE4 ,CA125 and CA199 might have clinical significance in early diagnosis and identification of ovarian cancer .

Traditional Chinese medicine （TCM） aromatherapy regulates the internal qi of the human body through the selection of specific aromatic medicinals， promoting the normal transportation and circulation of qi and blood and the coordination of zang-fu organs， and at the same time focusing on spiritual harmonization and nourishment， to achieve the therapeutic goal of nourishing both body and spirit. Its theoretical characteristics include the holism view of the unity of human beings and nature， the dynamic view of the balance of yin and yang， the pattern differentiation view of the three categories of disease cause， the preventive view of treating disease before it arises， and the regulation-care view of treating both body and spirit. From the perspective of qi theory， the theoretical connotation of TCM aromatherapy was analysed in depth， including the concept of life and disease， the concept of qi and blood， the theory of qi movement， and stressed the embodiment of the trinity view of body-qi-spirit in TCM aromatherapy， and the significant guidance of the principle of seeking the similar qi in TCM aromatherapy practice. This paper systematically summarized the theoretical characteristics and connotations of TCM aromatherapy， which could provide guidance for the practice of TCM aromatherapy.
