| 1 | Application of intraoperative O-arm-assisted real-time navigation technique for spinal fixation显示文摘This study explored the combined use of the O-arm and real-time navigation during spinal fixation. The clinical data for 60 patients undergoing spinal fixation, at Beijing Tsinghua Chang Gung Hospital between May 5, 2015 and May 1, 2017, were retrospectively analyzed. Pre-, intra-, and postoperative imaging findings were assessed. The patients were classified into the occipitocervical fusion(32 cases) and thoracic/lumbar/sacral spine fixation(28 cases, including 6 cases of percutaneous pedicle screw) groups. Lesion resections were performed microscopically. An O-arm, combined with real-time navigation, was used to assess spinal fixation. Efficacy was evaluated using operative times, X-ray times, screw positioning, and complications. Within the occipitocervical fusion group, 182 screws were placed in the cervical spine and 96 in the occipital bone. However, 6 screws penetrated the bone cortex and were adjacent to the vertebral arteries, based on O-arm three-dimensional imaging; therefore, the precision rate was 96.7%. Within the thoracic/lumbar/sacral spine fixation group, 148 pedicle screws were implanted, with 4 initially outside the vertebral body,yielding a precision rate of 97.3%. Ten percutaneous pedicle screws were implanted and well positioned. O-arm scans were performed 3 times/patient, with an average of 20–30 min/time. Screw implantation times were 5–7 min(cervical spine), 8–10 min(thoracic spine), and 6–8 min(lumbar spine). Intraoperative O-arm scans, combined with real-time navigation technology, allow real-time observation of screw angles and depths, improving the accuracy and safety of posterior screw fixations and reducing the radiation dose and frequency experienced by patients and surgeons. | Zhenxing Sun Dan Yuan Yaxing Sun Zhanquan Zhang Guihuai Wang Yi Guo Guoqin Wang Dongkang Liu Peng Chen Linkai Jing Feng Yang Peihai Zhang Huifang Zhang Youtu Wu Wei Shi James Wang | 2017 | Translational Neuroscience and Clinics2017，3，3： | 2 |

| 4 | The Influence of China's Export Trade on Technical Barriers to Trade and the Countermeasures显示文摘With the continuous development of China's economy,foreign trade in the national economy has been increasing.In foreign trade,export trade accounted for a large proportion,but due to technical level,export product structure,trade surplus and other reasons,in recent years China’s export products frequently encountered technical barriers to trade(TBT)in developed countries.In the development of contemporary international economic and trade,TBT are playing an increasingly important role,its influence and role has been far beyond the general trade measures.In the world,especially the developed countries,on their own technical advantages,apply more and more targeted,flexible,extensive,covert and mandatory TBT as an important means of protecting their industries.TBT has become the main means and advanced forms of national trade protectionism.China's accession to the WTO faced dual challenges in breakthroughs in foreign technical barriers and the protection of the domestic market.Due to the concentration of China's export market,the weakness of export products and the fact that China has not yet established its own TBT system,early warning mechanism and other reasons,TBT impact on China is significant.According to statistics,nearly five years,71%of China's export enterprises,39%of the export products are foreign TBT restricted,and thus cost and risk losses of Chinese enterprises are increasing year by year.In 2005 and 2006,about 25.1%and 31.4%of China's export enterprises were affected by foreign TBT,with total losses of US$28.8 billion and US$35.92 billion respectively.Agricultural products,electrical and mechanical,energy,mining,textile and other products are the main target products that developed countries implement TBT towards China.Therefore,our government and enterprises must take corresponding measures to resolve these unfavorable factors to ensure China's position and interests in international trade. | Yaxing Zhang Xiaolin Sun Longzhong yi Xue Yuan | 2019 | Global Finance Review2019，1，1： | 0 |
| 5 | Fluorescein sodium use during spinal ependymoma resection显示文摘Spinal ependymomas(SEs) are common adult intramedullary tumors; however,determining the absolute boundary between the tumor and the tumor residual may be difficult. We assessed outcomes following the use of fluorescein sodium(FS) during surgical removal of SEs. We performed a retrospective analysis of 112 patients with SEs who were treated at Beijing Tsinghua Changgung Hospital between December 2014 and December 2016. Each patient received intravenous FS(3–4 mg/kg) to determine the SE boundaries during surgery. Tumor removal efficiencies and tumor residuals were assessed using magnetic resonance imaging(MRI) at 10 days and 3 months after surgical recovery; McC ormick's spinal function classification was also performed at the 3-month follow-up. The complete tumor removal rate was 92%(103/112). Ninetyfour patients underwent tumor removal under fluorescent light, which provided distinctive tumor fluorescence. Tumor removal under white light was performed in18 patients; fluorescent images were invisible or indistinctive in these 18 patients. At the 3-month follow-up, sensory function(85.8%(91/106)) and movement(84.3%(86/102)) were improved in patients with pre-surgical dysfunction; urination and defecation functions were improved in 66.7%(16/24). The Mc Cormick spinal cord functional classifications, at the 3-month follow-up, showed significant differences in the percentages of patients with disease classified to each grade(I–IV), compared with preoperative classifications(each, P < 0.05). There was no MRI evidence of tumor relapse or residuals at the 3-month follow-up. FS use during the surgical treatment of SE enables complete tumor removal and detection of tumor residuals. | Zhenxing Sun Dan Yuan Yaxing Sun Zhanquan Zhang James Wang Yi Guo Guoqin Wang Dongkang Liu Peng Chen Linkai Jing Feng Yang Peihai Zhang Huifang Zhang Youtu Wu Wei Shi Guihuai Wang | 2017 | Translational Neuroscience and Clinics2017，3，3： | 0 |
| 6 | Surgical resection of a cervical intramedullary schwannoma: A case report and literature review显示文摘Schwannomas are the most common type of spinal tumor, and they most commonly occur in intradural extramedullary locations. Intramedullary schwannomas of the central nervous system are very rare and are difficult to diagnose using preoperative imaging. Here, we report a rare, tiny cervical intramedullary schwannoma and review the literature regarding the clinical presentation, magnetic resonance imaging, pathology,and surgical experience associated with this rare tumor type. | Peihai Zhang Zhenxing Sun Dan Yuan Yaxing Sun Zhanquan Zhang James Wang Yi Guo Guoqin Wang Dongkang Liu Peng Chen Linkai Jing Feng Yang Huifang Zhang Wei Shi Guihuai Wang | 2017 | Translational Neuroscience and Clinics2017，3，3： | 0 |
