Introduction: The impact of the COVID-19 has resulted in a decrease in presentations in emergency departments (ED). This has been influenced by societal restrictions, lockdowns and access to services. This study aims to observe the patterns in ED presentations for Bankstown-Lidcombe Hospital over the course of the initial COVID-19 pandemic wave. Methods: A retrospective review of all presentations to Bankstown-Lidcombe Hospital ED was conducted comparing monthly patient encounters from February-August for 2017-2020. Results: The total number of ED presentations was 42,225. There was a statistically significant reduction during 2020 of 9.8% between the study periods (1546 vs 1395, p = 0.014). The period of greatest reduction was seen in March-May, the strictest lockdown period for New South Wales. The admitting disciplines that showed a reduction in this time were colorectal (76.62%, p = 0.046), emergency (25.53%, p = 0.025), endocrine (31.82%, p = 0.026), orthopaedics (33.63%, p = 0.004), and vascular (35.71%, p = 0.017). The disciplines that showed an increase in presentations over the entire studied time were gynaecology (26.54%, p = 0.008), and psychiatry (17.46%, p = 0.011). Conclusion: There were significant reductions in total number of ED presentations. Notably, there were significant reductions across multiple admitting disciplines, as well as in a decrease in presentations for those in younger age groups.

Mechanism of Immune Hyporesponsiveness Induced by Recipientderived Immature Dendritic Cells in Rat Liver Transplantation

引用

Chinese Journal of Biomedical Engineering(English Edition) 2011年第1期20卷 36-46页

作者： LI Li ZHANG Sheng-ning RAN Jiang-hua LIU Jing LI Zhu ZHAO Yong-heng LI lai-bang Department of Hepatobiliary Pancreatic Surgery First People ＇s Hospital of Kunming Kunming Medical CollegeLiver Transplantation Center of Organ Transplantation Institute of Yunnan Province Kunming 650011China

Objective： The use of donor-derived immature dendritic cells （imDC） has become a promising approach to induce immune tolerance or immune hyporesponsiveness. However, donor-derived imDC needs to be harvested for a few days and transfused into the recipient in 5-10 days before transplantation, which is practically impossible in a clinical setting where donor organs are mainly harvested from cadavers. Moreover, donor-derived imDC might be cleared by allogeneic reaction offsetting induced immune tolerance or immune hyporesponsiveness. In our study, we further explored the underlying mechanism of immune hyporesponsiveness induced by donor-antigen-unloaded recipient-derived imDC by transfusing these imDC into rats in 1 day before liver transplantation. This paper is to study the mechanism of immune hyporesponsiveness induced by donor-antigen-unloaded recipient-derived imDC and its protection of liver grafts in rats. Methods： 40 SD rats （donor） and 40 male Wistar rats （recipient） were randomly divided into 4 groups： control, cyclosporine A （CsA）, mature DC （mDC）, and imDC; with 10 SD rats and 10 Wistar rats for each group. Animal models of acute graft rejection were established with these rats. Corresponding treatments were given before or after transplantation. In the control group, Wistar rats received no treatment other than liver transplantation. In the CsA group, Wistar rats underwent liver transplantation plus CsA treatment （10 mg/kg·d） in the starting day 2 after transplantation. For the mDC group, recipient-derived mDC （1 × 10^6/rat） were infused intravenously via the dorsal vein of the penis to recipient rats. For the imDC group, imDC （1× 10^6/rat） were injected into recipient rats via the dorsal vein of the penis. In each group, 5 recipients were executed at 10 days after transplantation; the remaining five recipients were kept for the observation of survival time. Blood samples were collected for the measurement of ALT and TBIL; IL-2, IFN-γ, IL-4 and IL-10 and l

史诗人物的思维模式和命运与那个时代的文化背景息息相关,依照康德的"先验综合判断理论"和"先验图式论",人在进行思维活动前,并不是"白板"一块,而是预先就有某种范畴、概念等图式,并且利用这种图式进行思维活动。文化背景不但是史诗人物思想观念的源泉,而且使史诗作者们也受这种"图式"的影响,从而在某种程度上"决定"了史诗人物的命运。

在353K的乙酰胺-尿素-NaBr-KBr熔体中,用恒电位电解法在Cu基片上制备了Sm-Fe合金膜。利用循环伏安法研究其不同熔体组分下的电化学行为。在Pt电极上,Fe2++2e→Fe是一步完全不可逆反应;可测得在FeCl2-乙酰胺-尿素-NaBr-KBr熔体中的Fe2+传递系数α=0.39,扩散系数D0=7.55×10-5cm2·s-1。Sm3+难以单独沉积,但可以被Fe2+诱导共沉积,在不同阴极电位下制备出含Sm量各异的合金膜。通过等离子发射光谱仪(ICP)检测合金膜成分,用XRD分析了制备态合金膜的晶相结构,用扫描电镜(SEM)观测合金膜的表面形貌,用振动样品磁强计(VSM)测量了合金膜的磁性能。结果表明,制备态Sm-Fe合金膜为非晶结构,在773K退火30s后则变为多晶结构;合金膜中Sm含量随沉积电位负移而增加;退火和Sm含量对Sm-Fe合金膜的磁性能有重要影响。

用固相反应烧结法制备了多晶体材料La2/3Ca1/3MnO(LCMO),La2/3(Ca0.5Ba0.5)1/3MnO(LCBMO)、La2/3Ba1/3MnO(LBMO),333La2/3(Sr0.5Ba0.5)1/3MnO3(LSBMO)和La2/3Sr1/3MnO3(LSMO),测量了它们在77K^800K的电阻和磁电阻特性。实验发现,通过一定的工艺技术制备出的CMR材料有强烈的相界效应,在低温下有大的磁电阻,且在Tc附近存在明显的从金属态向半导体态的转变;用自旋极化电子隧道效应和靠近居里点逾渗模型较好地解释了电阻和磁电阻行为;用非绝热小极化子跃迁模型对高温的电阻特性进行拟合处理,得到了激活能;同时发现退火处理对样品的电阻率有重要的影响。
