RESUMO
With the tightening of resource constraints and the proposal of the Chinese High-quality Development strategy, innovation-driven has emerged as a new option to balance economic progress with environmental protection. The paper takes Chinese inter-provincial panel data from 2007 to 2017 as a research sample and is based on a spatial Durbin model, investigating the association among green technology innovation (GTI), "green technology-institution" collaborative innovation, and ecological efficiency (EE), while fiscal decentralization is discussed as a moderating factor. According to the results, "green technology-institution" collaborative innovation is positively promoting ecological efficiency and causing spatial spillovers if the economic distance is taken into account. Compared with the single role of green technology innovation, collaborative innovation has a greater role in improving ecological efficiency. Among them, to improve ecological efficiency, it is best to develop green technology innovation and encourage production institutions in a coordinated manner. According to the moderating effect, fiscal decentralization moderates the impact of innovation collaboration on ecological efficiency in a negative way. Therefore, balancing the decentralization of local fiscal expenditures is important to promoting China's ecological efficiency. In addition, China should purposefully promote the degree of synergy between green technology innovation and related institutions for enhancing eco-efficiency.

OBJECTIVES: To investigate the expressions of Livin and phosphate and tension homology deleted on chromsome ten (PTEN) protein in the cancerous tissues of ovary endometriosis. METHODS: Immunohistochemistry EliVision was used to examine the expressions of Livin and PETN protein in 19 samples of ovary endometriosis cancerous tissues, 30 samples of ovary endometriosis tissues and 30 samples of ovarian benign tumor tissues. RESULTS: The positive expression rate of Livin in ovary endometriosis cancerous tissues (68%) was obviously higher than that in ovary endometriosis tissues (36%) and benign tumor tissues (13%)( P<0.05). The positive expression rate of PTEN in ovary endometriosis cancerous tissues (16%) was obviously lower than that in ovary endometriosis tissues (65%) and benign tumor tissues (80%)( P<0.01). There was no correlations between positive expressions of Livin and age, clinical stage, grading, histological type and lymphatic metastasis of ovary endometriosis cancer ( P>0.05), the same result was also found for PTEN. Livin and PTEN expression presented an obviously negative correlation in ovary endometriosis cancer ( r=-0.559, P=0.001). CONCLUSIONS: Up-regulation of Livin expression and down-regulation of PTEN may be involved in the occurrence and development of ovary endometriosis cancerization.
