目的探讨孕产妇血抗磷脂抗体水平检测及其对妊娠结局的影响。方法选取2016年7月至2018年11月于本院孕检及分娩的有病理性妊娠史的孕产妇708例作为病例组,另外选取同期于本院进行孕检和分娩、无血栓史、无免疫疾病史的正常孕产妇602名为正常组,比较两组APLs阳性率及妊娠结局(流产、早产、新生儿窒息等)。结果病例组单纯LA、ACL、β2GPⅠ阳性率及任意2项或3项阳性率、APLs总阳性率均明显高于正常组(P<0.05),病例组中APLs阳性患者早产发生率明显高于阴性患者(P<0.05)。正常组中,APLs阳性患者早产、新生儿窒息发生率明显低于阴性患者(P<0.05)。结论APLs在病理妊娠过程中发挥重要作用,其阳性可一定程度影响妊娠结局,临床工作中对于有病理妊娠史的孕产妇,应尽早进行APLs检测,及时采取干预措施,尽量改善病理妊娠状态,改善妊娠结局。

目的:探讨糖尿病与冠脉支架术后再狭窄的关系。方法:回顾性分析2000年6月-2002年3月成功进行PCI+Stenting治疗并复查冠脉造影者134例冠心病临床资料。根据直径狭窄是否≥50%,将其分为再狭窄组和未再狭窄组,并分析冠心病相关危险因素与支架内再狭窄的关系,探讨糖尿病是否为支架内再狭窄的独立危险因素。结果:134例共置入181只支架,其中61例(75只)发生支架内再狭窄,6个月再狭窄率为41.2%。在无再狭窄组和再狭窄组男性分别占78.9%和89.8%(P=0.147)。两组平均年龄(62.7±10.4岁)。高血压患病率(58.9%vs65.6%),高血压分级,高血压年限,吸烟,入院TC,LDL,在统计学上无显著差异。在冠心病的危险因素中,糖尿病病人在再狭窄组有12例占19.7%,无再狭窄组只有3例占4.2%(P=0.004);再狭窄组的入院血糖水平为5.70±1.56mmol/L,明显高于无再狭窄组5.14±0.82mmol/L(P=0.01)。结论:糖尿病是支架内再狭窄最有力的预测因子,而入院时血糖水平可能是支架内再狭窄发生的独立危险因子。

Frequency regulation of voltage source converter-based multi-terminal high-voltage direct current(VSC-MTDC)system with offshore wind farms enhances the frequency stability by compensating the power for a disturbed AC ***,it is difficult to reasonably allocate frequency-regulation resources due to a lack of coordination mechanisms between wind farms and the MTDC ***,it is difficult for the frequency control of the wind farms to manage changes in wind speed;and the risk of wind-turbine stalls is ***,based on the kinetic energy of wind turbines and the power margin of the converters,the frequency-regulation capability of wind turbines is evaluated,and a dynamic frequency-support scheme considering the real-time frequency-support capability of the wind turbines and system frequency evolution is proposed to improve the frequency-support performance.A power adaptation technique at variable wind speeds is developed;the active power in the frequency-support stage and restoration stage is switched according to the wind speed.A hierarchical zoning frequency-regulation scheme is designed to use the frequency-regulation resources of different links in the MTDC system with wind *** simulation results show that the novel frequency-regulation strategy maintains frequency stability with wind-speed changes and avoids multiple frequency dips.

分别用菊芋全粉和乳酸菌发酵菊芋全粉部分替代糙米粉,重点研究乳酸菌发酵菊芋全粉对糙米面团及米糕品质的影响。结果表明:未发酵和发酵菊芋全粉均显著降低了混合粉的峰值黏度、最终黏度和回生值,降低了面团的吸水率,增加了面团的形成时间和损耗模量。与未发酵菊芋全粉相比,发酵菊芋全粉使混合粉具有更低的峰值黏度、最终黏度和回生值,面团的吸水率更低,对糙米面团的发酵特性、糙米糕的质构、比容和贮藏特性影响较大,10%发酵菊芋组的糙米面团的体积在发酵至30 min时比对照组增加了34.08%,糙米糕的比容增加了25.30%,贮藏过程中的硬化速率降低了52.70%,表明乳酸菌发酵菊芋全粉可以缩短糙米面团的发酵时间,改善糙米糕的比容、质构和贮藏品质,且改善效果优于未发酵菊芋全粉。
