Pituitary carcinomas are rare malignant neoplasms with diagnostic and management challenges. Patients with pituitary carcinomas have extremely poor outcomes. In this report, the authors describe two cases of pituitary carcinomas with intraspinal metastasis (Case 1: 42-year-old man with a history of pituitary adenoma 16 years ago developed an intraspinal lesion at C4-C5; Case 2: 26-year-old women with a history of growth hormone-producing pituitary adenoma 9 years ago developed intraspinal lesion in the sacral canal). Both patients underwent spine surgery. The intraspinal lesions were confirmed as metastatic pituitary carcinomas based on the histomorphology and immunohistochemical stains. The authors reviewed the literature for the diagnosis, treatment, and prognosis of intraspinal metastasis from pituitary carcinomas.

With the rapid development of wind power, the conventional power auxiliary services have not met the requirements of wind power grid-connected power generation in full. In order to relieve the grid-connected and integration issues of wind power, wind power was put forward to participate in ancillary ser-vices on the basis of related research. Aiming at the feasibility problem of wind power auxiliary service, the paper builded the evaluation index system for wind power aux- iliary services firstly. Secondly, the article constructed the evaluation model of wind power auxiliary services based on structural equation model (SEM), and researched the identification and applica- tion of the SEM of wind power auxiliary services. Finally, the conclusion was presented.

Keyword: Energy Internet; Renewable energy; Energy power system. Abstract. In order to promote the large-scale use of distributed renewable energy and improve en- ergy efficiency, many countries started to pay close attention to the development of energy Internet. Europe, the United States, Japan and other developed countries has made some breakthrough in the field of energy Internet construction. The paper mainly analyzed and summarized the development of energy Internet. Some successful projects of energy Internet in the developed countries are intro- duced. And then the paper summarized the status quo and development plan of China's energy In- ternet. Finally, gave some conclusions for the paper. We held that China draw experience from the development of energy Internet in developed countries and find the development road for the con- struction of energy Internet according to practice of the nation

In recent years, the growth rate of wind power in China installed capacity has tended to be sta-ble, and the competition among wind power equipment manufacturers has become increasingly fierce. In order to analyze the industrial performance of wind power in China, the paper summarized the status quo of China’s wind power, and then used the Data Envelopment Analysis (DEA) model to analyze the industrial performance of China’s wind power from 2010 to 2014. We found that: during the analysis period, the industrial performance of wind power equipment manufacturing was best in 2010. Due to fierce competition between wind turbines manufacturers, the industrial performance was in the declining trend in the next three years. By 2014, the performance increased again, but did not reach the best state. Besides, the technical efficiency has been better than scale efficiency. 1 INSTRUCTION With the adjustment of energy structure, the renewable energy, especially the wind power, was facing a historic opportunity for development in China. In recent years, wind power industry itself has been also in the state of constant adjustment. The scale of projects approval, equipment tendering and projects construction of the wind power all has bigger growth. Besides, the grid-connected and integration issues of China’s wind power were also alleviated, due to the construction of UHV grid and the implementation of interconnection policy and subsidies policy. Therefore, the installed capacity of wind power in China maintained a rapid growth. At present, the market concentration degree of wind power manufacturing industry in China has been in a downward trend, but it is still higher [Yuanxin Liu, 2015]. According to the new installed capacity situation, the domestic market shares of the top 20 wind turbine manufacturers were about 90%. Although the market demand of domestic wind power grew steadily, the competition between wind power manufacturers was still fierce, and the overcapacity problem of wind power industry was stall serious. Both fierce competition and overcapacity have important influence on the industrial efficiency, so it is significant to research on the industrial performance of China’s wind power. In recent years, large numbers of scholars researched the China’s wind power industry from different aspects, such as wind power price and policy [Ping Lu, 2013] [Ting-Ting Mi, 2012], development bottleneck [Zhao Dong, 2009] [Hua BAI, 2012], sustainable development [Zheng-ming WANG, 2008] [Weidong Shi, 2011]and wind power industry innovation [Yuanying CHI, 2008] [Jorrit Gosens, 2013]. The research literatures of China’s wind Power industry have been comprehensive. Based on the exiting research literatures, the paper adopted the DEA model to analyze the industrial performance of China’s wind power.

These This paper selects 455 manufacturing firms in Shanghai and Shenzhen Stock Exchanges from 2007 to 2011 as study object, establishes a modified Cobb-Douglas production function, and empirically tests the cumulative effect of RD however, the promotion effect is not significant in 2011.

This paper deals with the problem of robust tracking control with adaptation mechanism to improve transient performance in time-response. A linear time-invariant system with time-varying ellipsoidal uncertainty is considered. The proposed controller affinely depends on the estimations of parameters, which are adjusted on-line according to the error between the state trajectory of the plant and that of target model. The application of this approach to the yaw control of a small-scale helicopter mounted on an experiment platform shows the effectiveness.

To evaluate the efficacy of third generation spinal instrumentation such as TSRH, CD and ISOLA for the treatment of adult scoliosis.Thirty-five adult scoliosis patients including adult idiopathic and degenerative scoliosis were all surgically treated with third generation instrumentation such as TSRH, CD and ISOLA from July 1999 to January 2003. Preoperative mean cobb angles of major curves of the frontal plane was 58.1 degrees (42 degrees -95 degrees ). The patients received anterior combined with posterior correction or single posterior procedure. Mean follow-up was 20 months (10 - 48 months). Preoperative and postoperative Cobb angles of the frontal plane and sagittal plane and distance between C(7) and CVSL were measured. We assessed the subjective efficacy by questionnaire.Clinical appearance of all patients improved significantly. Mean correction of major curves of the coronal plane was 53.2%. Mean lost of correction of the coronal plane in the last follow-up was 4.3 degrees , distance between the midline of C(7) and CVSL was corrected from 2.6 cm to 0.24 cm. Questionnaire in the follow-up showed that 89.3% patients were satisfied with operation results. Two cases occurred pneumatothorax and haematothorax. Three cases still complained about low back pain in 1 year after operation, among which 2 were adjacent degeneration and 1 was pseudarthrosis.Imageology assessment and patients self-evaluation shows that the third generation instrumentation could gain good correction and trunk balance in the treatment for adult scoliosis. And patients are more satisfied and have less complications.
