Objective:To investigate the clinicopathological characteristics and immunohistochemical features of tumor-infiltrating lymphocyte(TIL) in ovarian serous adenocarcinoma,and their clinical value.Methods:The immunohistochemistry was used to observe 68 ovarian serous adenocarcinomacases'immunohistochemical features,and their correlations with clinicopathological characteristics were analyzed.Results:There were 43 cases with a large amount of TIL infiltrating in the 68 cases of serous adenocarcinoma,account for 63.24%.There were significant differences on the with or without a large amount of TIL infiltrating among the different tumor grade,different clinical stage,and different CA125 level (P < 0.05).The numbers of CD3 +,CD4 + and CD8 + TIL in the cancer nest were significantly less than those in the stroma,with significantly statistical difference (P < 0.05),Meanwhile the ratio of CD4 +/CD8 + in the cancer nest was significantly less than that in the stroma(P<0.05).The ratio of CD4 +/CD8 + in the cancer nest and stroma at stage Ⅲ and with poor differentiation was significantly lower than in those at stage Ⅰ-Ⅱ and with good differentiation(P<0.05).Meanwhile the ratio of CD8 +/FoxP3 + Treg in the cancer nest was less than that in the stroma(P<0.05).The ratio of CD8 +/FoxP3 + Treg in the cancer nest at stage Ⅲ and with poor differentiation tumor was significantly lower than in those at stage Ⅰ-Ⅱ and with good differentiation(P<0.05).The expression of GzmB in the cancer nest at stage Ⅲ and with poor differentiation tumor was significantly lower than that in the cancer nest at stage Ⅰ-Ⅱ and with good differentiation tumor(P<0.05).Conclusions:With or without a large amount of TIL is related to tumor grade,clinical stage,and CA125 level inovarian serous adenocarcinoma.The numbers of TIL in ovarian serous adenocarcinoma increase considerably,but mainly in the stroma,and which may be related to several factors such as tumor cell differentiation and clinical stage.

Dry eye is a common ophthalmic disease caused by eye maladjustment due to meibomian gland dysfunction (MGD), which is often accompanied by symptoms such as increased tear film osmotic pressure and ocular surface inflammation. In the treatment of dry eye patients, dredging gland obstruction caused by meibomian gland secretion is an effective treatment method. Based on electrothermal effect and hyperelasticity of the silicone, an auxiliary treatment instrument for MGD is designed, which can improve the blood circulation of the glands through heat compress and massage to achieve the purpose of dredging the meibomian glands. The therapy device can display the temperature and pressure during the treatment in real time, so that the surgeon can grasp the progress of the treatment in real time. The therapy device constructs a user-oriented interactive interface based on parametric modeling method, which can be customized by 3D printing according to the user's eyeball geometric parameters. The designed therapeutic device was finally tested on New Zealand white rabbits. The experimental results show that the therapeutic device has significant effectiveness and safety, as well as clinical application prospects.
