| 1 | Distribution and treatment of harmful gas from heavy oil production in the Liaohe Oilfield, Northeast China显示文摘The distribution and treatment of harmful gas (H 2 S) in the Liaohe Oilfield, Northeast China, were investigated in this study. It was found that abundant toxic gas (H 2 S) is generated in thermal recovery of heavy oil. The H 2 S gas is mainly formed during thermochemical sulfate reduction (TSR) occurring in oil reservoirs or the thermal decomposition of sulfocompounds (TDS) in crude oil. H 2 S generation is controlled by thermal recovery time, temperature and the injected chemical compounds. The quantity of SO 4 2-in the injected compounds is the most influencing factor for the rate of TSR reaction. Therefore, for prevention of H 2 S formation, periodic and effective monitoring should be undertaken and adequate H 2 S absorbent should also be provided during thermal recovery of heavy oil. The result suggests that great efforts should be made to reduce the SO 4 2-source in heavy oil recovery, so as to restrain H 2 S generation in reservoirs. In situ burning or desulfurizer adsorption are suggested to reduce H 2 S levels. Prediction and prevention of H 2 S are important in heavy oil production. This will minimize environmental and human health risks, as well as equipment corrosion. | Zhu Guangyou Zhang Shuichang Liu Qicheng Zhang Jingyan YangJunyin Wu Tuo Huang Yi Meng Shucui | 2010 | Petroleum Science2010，7，3： | 6 |
| 2 | Locally transplanted enteric glia improve functional and structural recovery in a rat model of spinal cord injury显示文摘<正>BACKGROUND:We have previously reported that adult enteric glia(EG) facilitate the growth of transected dorsal root axons into the uninjured spinal cord to form functional connections with their targets. OBJECTIVE:The present study investigated the effects of EG on spinal cord function,tissue injury, and axonal regeneration following transplantation into injured rat spinal cords,according to histological and functional outcomes. DESIGN,TIME AND SETTING:A randomized controlled animal experiment was performed at McMaster University,Canada from January 2006 to March 2008. MATERIALS:EG were isolated from rat intestine. METHODS:One week following spinal cord crush,female Wistar rats were injected with an EG suspension(2μL,1×10~5/μL,n=10) or with the same volume of fresh culture medium alone(control animals,n=11).The third group did not receive any injection following laminectomy and served as the sham-operated controls(n=5). MAIN OUTCOME MEASURES:Behavior was tested prior to transplantation and weekly following transplantation,with nine behavioral examinations in total.Open field,hind limb placement response, foot orientation response,and inclined plane test were utilized.Immediately following the final behavioral examination,spinal cord T_9 to L_1 segments were harvested for immunohistochemical and hematoxylin-eosin staining to determine astroglial scarring,axonal regeneration and spinal cord lesion size. RESULTS:Rats with EG transplantation exhibited significantly better locomotor function with reduced tissue damage,compared with the control rats.Cystic cavities were present 2 months after injury in spinal cords from both control groups.In contrast,rats injected with EG did not present with cystic lesions.In addition,the injury site consisted of cellular material and nerve fibers,and axonal regeneration was apparent,with dense labeling of neurofilament-positive axons within the injury site. Moreover,regenerating axons were intimately associated with transplanted EG CONCLUSION:These data indicated that EG enhanced functional improvement,which was associated with reduced tissue damage and axonal regeneration following transplantation into injured spinal cords. | Shucui Jiang Mohammad I.

| 4 | Role of Elevated Thrombospondin-1 in Kainic Acid-Induced Status Epilepticus显示文摘Previous studies have suggested that thrombospondin-1(TSP-1) regulates the transforming growth factor beta 1(TGF-b1)/phosphorylated Smad2/3(p Smad2/3) pathway. Moreover, TSP-1 is closely associated with epilepsy. However, the role of the TSP-1-regulated TGFb1/p Smad2/3 pathway in seizures remains unclear. In this study, changes in this pathway were assessed following kainic acid(KA)-induced status epilepticus(SE) in rats.The results showed that increases in the TSP-1/TGF-b1/p Smad2/3 levels spatially and temporally matched the increases in glial fibrillary acidic protein(GFAP)/chondroitin sulfate(CS56) levels following KA administration.Inhibition of TSP-1 expression by small interfering RNA or inhibition of TGF-b1 activation with a Leu-Ser-Lys-Leu peptide significantly reduced the severity of KA-induced acute seizures. These anti-seizure effects were accompanied by decreased GFAP/CS56 expression and Smad2/3 phosphorylation. Moreover, inhibiting Smad2/3 phosphorylation with ponatinib or SIS3 also significantly reduced seizure severity, alongside reducing GFAP/CS56 immunoreactivity. These results suggest that the TSP-1-regulated TGF-b1/p Smad2/3 pathway plays a key role in KA-induced SE and astrogliosis, and that inhibiting this pathway may be a potential anti-seizure strategy. | Yurong Zhang Mengdi Zhang Wei Zhu Xiaohong Pan Qiaoyun Wang Xue Gao Chaoyun Wang Xiuli Zhang Yuxia Liu Shucui Li Hongliu Sun | 2020 | Neuroscience Bulletin2020，36，3： | 1 |

| 6 | Local discrimination scheme for some unitary operations显示文摘It has been shown that for two different multipartite unitary operations U_1 and U_2, when tr(U_1~?U_2) = 0, they can always be perfectly distinguished by local operations and classical communication in the single-run scenario. However, how to find the detailed scheme to complete the local discrimination is still a fascinating problem. In this paper, aiming at some U_1 and U_2 acting on the bipartite and tripartite space respectively, especially for U_1~?U_2 locally unitary equivalent to the high dimensional X-type hermitian unitary matrix V with trV = 0, we put forward the explicit local distinguishing schemes in the single-run scenario. | TianQing Cao Fei Gao GuoJing Tian ShuCui Xie QiaoYan Wen | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，9： | 0 |
