摘要：目的对新医改前后齐齐哈尔市住院病人满意度进行对比,分析满意度提高或降低的归因。方法采用自行设计的调查问卷,对新医改后齐齐哈尔市5所综合医院156例患者进行满意度调查,并将结果与新医改前进行纵向对比分析。结果整体满意度为94.2%,较新医改前有所提高。在对医疗过程的满意度方面,绝大部分项目的满意度均提高;只有耐心倾听患者述说病情、医护人员维护病人安全等项目的满意度有所降低。在对医院工作人员服务态度的满意度方面,只有护士会迅速回应患者需要并提供协助的满意度有所降低,其他项目的满意度均大幅提升。结论加强医患之间的沟通与交流,加强医疗服务素养,提升主动服务意识,加大政府投入力度,扩大医保用药范围。

摘要：目的对社区人群椎基底动脉颅内段狭窄的患病情况及危险因素进行调查统计。方法采用自行设计的问卷进行面对面的询问调查、体格检查及实验室检测,通过统计学软件对社区人群椎基底动脉颅内段狭窄的相关因素进行Logistic回归分析。结果多元回归分析显示,多因素中的尿酸(UA)、收缩压(SBP)、低密度脂蛋白(LDL-C)、性别、年龄、肥胖、腰围、血糖为社区人群椎基底动脉颅内段狭窄的危险因素,高密度脂蛋白(HDL-C)为社区人群椎基底动脉颅内段狭窄的保护因素。结论男性及三高人群是社区椎基底动脉颅内段狭窄的危险因子,在临床上应当作为干预和防控的方向。

摘要：The newly emerged two-dimensional(2D) semiconducting materials, owning to the atomic thick nature and excellent optical and electrical properties, are considered as potential candidates to solve the bottlenecks of traditional semiconductors. However, the realization of high performance 2D semiconductorbased field-effect transistors(FETs) has been a longstanding challenge in 2D electronics, which is mainly ascribing to the presence of significant Schottky barrier(SB) at metal-semiconductor interfaces. Here, an additional contact gate is induced in 2D ambipolar FET to realize near ideal reconfigurable FET(RFET)devices without restrictions of SB. Benefitting from the consistently high doping of contact region, the effective SB height can be maintained at ultra-small value during all operation conditions, resulting in the near ideal subthreshold swing(SS) values(132 mV/decade for MoTe2 RFET and 67 mV/decade for WSe2 RFET) and the relatively high mobility(28.6 cm2/(Vs) for MoTe2 RFET and 89.8 cm2/(V s) for WSe2 RFET). Moreover, the flexible control on the doping polarity of contact region enables the remodeling and switching of the achieved unipolar FETs between p-type mode and n-type mode. Based on such reconfigurable behaviors, high gain complementary MoTe2 inverters are further realized. The findings in this work push forward the development of high-performance 2D semiconductor integrated devices and circuits.
