Title: The drivers of corporate environment inputs: Based on neo-institution theory evidence from Chinese listed biological and other companies Authors: Guo, Rui; Tao, Lan; Yan, Liang; Chen, Lianfang; Wang, Haijun Abstract: From corporate internal governance structure and external institutional environment, this study uses a legitimacy perspective of intuitional theory to analyze the main influence factors on corporate environmental protection inputs and propose some hypotheses. With the establishment of empirical models, it analyzes the data of 2004-2009 listed biological and other companies in China to test the hypotheses. The findings are concluded that in internal institutional environment, the nature of the controlling shareholder, the proportion of the first shareholder in the ownership structure, the combination of chairman and general manager in board efficiency and the intensity of environmental laws and regulations of the industry in external institutional environment have an significant impact on the behaviors of corporate environmental protection inputs.

Title: The effectiveness of isometric exercises as compared to general exercises in the management of chronic non-specific neck pain Authors: Muhammad Khan; Rabail Rani Soomro; Syed Shahzad Ali Abstract: To evaluate the effectiveness of isometric exercises as compared to general exercises in chronic non-specific neck pain. For this randomised controlled trial total 68 patients (34 each group) with chronic non-specific neck pain were recruited from Alain Poly Clinic and Institute of Physical Medicine & Rehabilitation Dow University of Health Sciences Karachi between May, 2012 and August, 2012. Simple randomisation method was used to assign participants into isometric exercise group and general exercise groups. The isometric exercise group performed exercises for neck muscle groups with a rubber band and general exercises group performed active range of movement exercises for all neck movements. Patients in both groups received 3 supervised treatment sessions per week for 12 weeks. Visual Analogue Scale (VAS), North wick Park Neck Pain Questionnaire and goniometer were used to assess pain, disability and neck range of movements at baseline and after 12 weeks. Both interventions showed statistically significant improvements in pain, function and range of movement p = 0.001for isometric exercise group, p = 0.04 for general exercises group and p= 0.001 for range of movement. However, mean improvements in post intervention VAS score and North wick Park Neck Pain Questionnaire score was better in isometric exercises group as compared to general exercise group. In conclusion, both interventions are effective in the treatment of chronic non-specific neck pain however; isometric exercises are clinically more effective than general exercises.

Title: Research on chemotherapy efficacy of twist gene on cervical cancer cells to paclitaxel Authors: Sun, Zhenchang; Zhang, Dan; Cui, Yingying; Cheng, Liangxing; Cao, Jingyu; Wu, Xiaolong Abstract: The silent Twist gene may increase the sensitivity of cervical cancer cells chemotherapy to paclitaxel, thus was a new idea to improve the efficacy of cancer chemotherapy. The aim was to explore chemotherapy sensitivity of silent Twist gene increased cervical cancer cells to paclitaxel through study the proliferation and apoptosis of cervical cancer Twist gene after paclitaxel treatment. Cervical carcinoma Caski cells and Hela cells was cultured in vitro, mRNA gene expression was detected by using semi-quantitative, fluorescence quantitative PCR, and transferred to Caski cells transiently, and affected with paclitaxel solution of five kinds of different concentrations of 0.001, 0.01, 0.1, 1, 10 umol/L respectively. Then the results of <0.05). Every 12h after 36h, the expression inhibition rate in two groups of Caski cells that has transfected this study was Twist gene expression in Caski cells was higher than in Hela cells, which was of significant difference (p siRNA1 and siRNA2 were 20.3%, 38.2%, 33%, 24%, 68.6%, 50.8% respectively. After 48h in five different concentrations of paclitaxel effect, the cell growth inhibition rate of group siRNA2 with the best transfection efficiency was obviously higher than that of negative control group and blank control group, and the growth inhibition rates showed concentration dependence (p<0.05). It can be concluded that Twist gene in Caski cell was of high expression and the silent Twist gene could inhibit Caski cell proliferation and promote its apoptosis, thus to improve the chemotherapy sensitivity of Caski cells.

Study of the damage rate caused by intervertebral foramen type inside and outside and the pass of the intervertebral DRG RF puncture way

Title: Study of the damage rate caused by intervertebral foramen type inside and outside and the pass of the intervertebral DRG RF puncture way Authors: Sun, Jiashu; Zhang, Haitao Abstract: This paper was to analyze and contrast the damage rate on the thoracic segment different position of the dorsal root ganglion (dorsal root ganglion, DRG) caused by different puncture path in radiofrequency ablation, thus the best RF target way for the thoracic segment of different types of DRG was confirmed. According to the difference of puncture and ablation damage way, 14 segmental spinal specimens were randomly divided into three groups, and then conducted DRG radiofrequency damage on percutaneous puncture path according to the type of DRG position. The damage effect of different puncture path by the judgment standard of the result of pathology analyzed. The experiment showed that RF damage of group A were 72.58+/-18.88%, 54.16+/-24.84% and 32.85+/-28.11%; that of group B were 771.86+/-15.15% and 72.02+/-17.86%, 57.14+/-18.02% and 52.47+/-20.64%, 68.75+/-14.63% and 71.78±16.00%; and that of group C were 82.46+/-14.10%, 81.53+/-11.81% and 80.83+/-13.33%. It was concluded that the singleness of DRG puncture route is one of the important reasons for the poor thoracic segments DRG radio frequency (RF) ablation effect. While according to the type of DRG different positions with double joint puncture path can significantly improve the rate of DRG RF damage.
