Asian Pacific Journal of Tropical Medicine 2016年第6期9卷 553-558页

作者： Gao-Rong Deng qiang Ling Bing-Hua Wu Yu-Ying Dong Xiang Gao tai-qiang Li Xin Miu Zong-Fang Li The Second Affiliated Hospital of Xi'an Jiaotong University Department of Orthopedics Nanchang University Fourth Affiliated Hospital

Objective: To explore the protection and molecular mechanism of histone deacetylase inhibitors(HDACIs) on the spleen of rats with hemorrhagic shock. Methods: A total of 60 SPF male SD rats were selected for the modeling of severe hemorrhagic shock using the method of arterial and venous cannulation with the time-divided bleeding. The measurement of mean arterial blood pressure and blood lactic acid was used to verify the modeling. The modeled rats were randomly divided into shock group, shock+suberoylanilide hydroxamic acid(SAHA) group, shock+autogenous transfusion group, and shock+SAHA+autogenous transfusion group. Three hours after the treatment, the spleen of rats was collected and TUNEL method was employed to detect the apoptosis of spleen cells in each group. Afterwards, real-time PCR and western blot were employed to detect the expression of BCL-2, BAX, and caspass3 in the spleen of rats in each group. Results: A total of 55 rats had successful modeling of severe hemorrhagic shock, with success rate of 92%. Cell apoptosis in the severe hemorrhagic model group was the most serious. After the intervention of HDACIs and the autogenous transfusion, the tissue injury was a bit recovered. Cell apoptosis was least in the shock+SAHA+autogenous transfusion group(P<0.05). After the intervention of HDACIs and the autogenous transfusion, the relative expression of BCL-2 was significantly increased(P<0.05), with highest relative expression of BCL-2 in shock+SAHA+autogenous transfusion group(P<0.05). After the intervention of HDACIs and the autogenous transfusion, the relative expression of BAX was significantly decreased(P<0.05), with lowest relative expression of BAX in the intervention group of single HDACIs. The change in the expression of caspass3 was similar to BAX, namely the relative expression of caspass3 was significantly decreased after the intervention of HDACIs and the autogenous transfusion(P<0.05). Conclusions: HDACIs and autogenous transfusion can all protec

Effect of heat shock on the susceptibility of Frankliniella occidentalis(Thysanoptera：Thripidae) to insecticides

Journal of Integrative Agriculture 2016年第10期15卷 2309-2318页

作者： ZHANG Bin ZUO tai-qiang LI Hong-gang SUN Li-juan WANG Si-fang ZHENG Chang-ying WAN Fang-hao Key Laboratory of Integrated Crop Pest Management of Shandong College of Agronomy and Plant Protection Qingdao Agricultural University Qingdao 266109 P.R.

China

Currently, insecticides are considered as the primary approach for controlling western flower thrips, Frankliniella occidentalis（Pergande）（Thysanoptera： Thripidae）. However, the heavy use of insecticides resulted in high insect resistance and serious environmental pollution. Given its characteristics of ease of operation and environmental friendliness, insect control using high temperature is receiving considerable renewed research interest. However, although the combination of insecticides and high temperature to control F. occidentalis has been studied before, few studies have focused on the short-term effect of such treatment. In a laboratory study, F. occidentalis adults and second-instar nymphs were exposed to 45℃ for 2 h. Then, their susceptibility to acetamiprid, spinosad, methomyl, and beta-cypermethrin was tested after different periods of recovery time（2–36 h）. Additionally, the specific activity of three detoxification enzymes（esterase, glutathione S-transferase, and cytochrome p450（CYP） monooxygenase） of the treated insects was determined. The results indicated that the fluctuation of susceptibility to insecticides and detoxification enzyme activity during F. occidentalis recovery from heat shock are related. Furthermore, several recovery time points（2, 30, and 36 h） of significant susceptibility to four tested insecticides compared with the control were found during the treatment of adults that were heat-shocked. Recovery time points of higher susceptibility compared with the control depended on different insecticides during the second-instar nymph recovery from heat shock. Interestingly, the fluctuation of CYP monooxygenase activity exhibited a trend that was similar to the fluctuation of susceptibility to insecticides（especially spinosad） during the recovery from heat shock of adults. In addition, the glutathione S-transferase and CYP monooxygenase activity trend was similar to the trend of susceptibility to spinosad during the recovery from heat shoc

The recipients were mainly the patients with hepatocellular carcinoma. The one-year patient survival rate was 80.8% with a median follow-up of 422（2-696） days. Among the five mortalities during the follow-up,three died of tumor recurrence. In terms of post-transplant complications, 9 recipients（34.6%） experienced early allograft dysfunction, 1（3.8%） had non-anastomotic biliary stricture,and 1（3.8%） was complicated with hepatic arterial *** of these complications resulted in patient death. Notably,primary non-function was not observed in any of the ***： With careful donor selection, liver transplant from deceased donors can be performed safely and plays acritical role in overcoming the extreme organ shortage in China.

针对对称分量法实现三相逆变器在不平衡负载下输出电压的正、负、零序分量补偿,以维持三相输出电压的平衡,该方法在三相负载严重不平衡时,其不平衡度仍然较大,且运算量大,适时性差,不易控制等问题。本文提出了一种三相逆变电源的输出电压分相控制的方法,分别对三相逆变器输出的线电压进行控制,以实现三相电压的平衡。理论和仿真分析表明,该方法能够使三相最大不平衡度从传统对称分量法的5.49%降到1%左右,在负载不平衡度达到200%的情况下,三相电压输出也能适时、稳定、可靠的达到平衡,有效地补偿因不平衡负载引起的逆变器输出电压畸变,从而保证逆变器在带任意不平衡负载时仍能维持三相平衡的输出电压。

简要叙述了国内常见几种旋流燃烧器的稳燃措施,从燃烧器流场和煤粉颗粒运动轨迹的角度分析了对低挥发份煤燃烧稳定性的影响。介绍了新近研究的花瓣稳燃器及其流场特点。指出该稳燃器在加速煤粉气流与高温回流烟气之间的混合时,避免煤粉气流过早向二次风扩散,引导煤粉颗粒进入回流区,有利于燃用低挥发份煤和低负荷稳燃及降低NOx排放等。另外,还介绍了ABT公司最近推出的“弓形”低NOx燃烧器;最后,提出了旋流燃烧器,并提出了旋流燃烧器结构优化的建议。

针对旋流燃烧器燃烧低挥发份煤的稳燃问题,介绍了扩口、扩锥、浓淡燃烧、齿环稳燃器等国内外的稳燃措施,采用数值方法模拟了旋流燃烧器一次风流场,详细分析了旋流燃烧器的流场特性。分析得出,扩口、扩锥、浓淡燃烧等稳燃措施没有考虑煤粉气流进入炉膛与高温烟气的迅速混合问题。在这些稳燃措施的流场中,煤粉气流进入炉膛,除脉动外,首先沿回流区外缘流动,向外扩张,而不是迅速与热烟气混合,因此,对于低挥发份煤不能起到良好的稳燃作用。提出了解决旋流燃烧稳燃问题的新的研究方向,拓展了稳燃理论,介绍了花瓣形稳燃器,为旋流燃烧稳燃技术的发展提供了新思路。
