High risk factors for pulmonary fungous infection in intensive care units of neurosurgery

ZHU Wenyu, TAN Liping, CHEN Xiangfeng, HUANG Qiang, LAN Qing

《医学前沿（英文）》 2007年 第1卷 第3期   页码 299-303 doi: 10.1007/s11684-007-0057-8

摘要： By analyzing the high risk factors for pulmonary fungous infection in intensive care units of neurosurgery, the strategy of early diagnosis and treatment was explored. According to the domestic diagnostic standard on pulmonary fungous infection, clinical data on 58 patients with the infection in our department were analyzed. One hundred and seventeen strains of fungi were separated from the 58 cases. Candidiasis was the most frequent type, accounting for 92.3% of the cases. Conditions such as the severity of primary diseases, long-time coma, long-term use of broad-spectrum antibiotic, abuse of glucocorticoid, the open airway, and some invasive intubations, may be regarded as high risk factors for pulmonary fungous infection. Fluconazole showed good clinical effects on the treatment of fungous infection. To eliminate these high risk factors, early diagnosis and the use of prophylactic antifungal agents can help reduce the incidence of pulmonary fungous infection.

Investigation into the influence of diffuser stagger angles on the flow field and performance of a centrifugal compressor

XI Guang, DING Haiping, YUAN Minjian, ZHANG Chunmei, ZHOU Li

《能源前沿（英文）》 2007年 第1卷 第3期   页码 290-294 doi: 10.1007/s11708-007-0041-7

摘要： The performance graphs of a centrifugal compressor under different diffuser stagger angles were measured, and the influence of different stagger angles of vanes on the stage performance as well as flow field was investigated numerically. The results show that the performance graph shifts when the diffuser stagger angle is altered; the influence of different stagger angles of vanes on the flow field inside the centrifugal compressor is great. Large scale vortices appear on the diffuser vane under larger incidence. An optimal diffuser stagger angle should exist at a specified flow rate to make the characteristic of the flow optimized. The incidence corresponding to the highest efficiency is not 0º at the design condition.

White blood cell count and the incidence of hyperuricemia: insights from a community-based study

Jian Liu, Pingyan Shen, Xiaobo Ma, Xialian Yu, Liyan Ni, Xu Hao, Weiming Wang, Nan Chen

《医学前沿（英文）》 2019年 第13卷 第6期   页码 741-746 doi: 10.1007/s11684-017-0579-7

摘要： Hyperuricemia (HUA) is a risk factor for chronic kidney disease (CKD). The relationship between HUA and white blood cell (WBC) count remains unknown. A sampling survey for CKD was conducted in Sanlin community in 2012 and 2014. CKD was defined as proteinuria in at least the microalbuminuric stage or an estimated GFR of 60 mL/(min·1.73 m ). HUA was defined as serum uric acid>420 µmol/L in men and>360 µmol/L in women. This study included 1024 participants. The prevalence of HUA was 17.77%. Patients with HUA were more likely to have higher levels of WBC count, which was positively associated with HUA prevalence. This association was also observed in participants without CKD, diabetes mellitus, hyperlipidemia, or obesity. Multivariate logistic regression analysis showed that WBC count was independently associated with the risk for HUA in male and female participants. Compared with participants without HUA, inflammatory factors such as high-sensitivity C-reactive protein, tumor necrosis factor-α and interleukin 6 increased in participants with HUA. Hence, WBC count is positively associated with HUA, and this association is independent of conventional risk factors for CKD.

摘要： After the establishment of big reservoirs, the environment along the Yangtze River, China, has changed. The alterations may influence people’s health. This study intended to find out the relationships between the environmental changes and the incidence of hemorrhagic fever with renal syndrome (HFRS) in the Big Three Gorges Area (BTGA) of Chongqing Municipality, China. Land-use thematic maps were applied in the research. The results show that there was a significant relationship between the land-use change in the grass area and the cumulative HFRS incidence (correlation coefficient= − 0.676, = 0.011). In the BTGA, the land was submerged because water filled in the reservoir, and meanwhile, the government called for returning land for farming to forestry. It is concluded that the changes of environment may influence the incidence of HFRS.

Analysis of flow and heat transfer characteristics of porous heat-storage wall in greenhouse

OUYANG Li, LIU Wei

《能源前沿（英文）》 2008年 第2卷 第4期   页码 406-409 doi: 10.1007/s11708-008-0094-2

摘要： The flow and heat transfer characteristics of porous heat-storage wall in greenhouse are studied by using the one-dimensional steady energy two-equation model for saturated porous medium. The results show that the heat exchange between the air and the solid matrix of the porous heat-storage wall depends upon the inlet air velocity, the porosity and the permeability of porous medium, and the thermal conductivity of the solid matrix. Because the incidence of solar radiation on the porous heat-storage wall is not uniform, the new composite porous solar wall with different porosity is proposed to reduce the disadvantageous effect.

Immunological and virological characteristics of human immunodeficiency virus type 1 superinfection: implications in vaccine design

《医学前沿（英文）》 2017年 第11卷 第4期   页码 480-489 doi: 10.1007/s11684-017-0594-8

摘要：

Superinfection is frequently detected among individuals infected by human immunodeficiency virus type I (HIV-1). Superinfection occurs at similar frequencies at acute and chronic infection stages but less frequently than primary infection. This observation indicates that the immune responses elicited by natural HIV-1 infection may play a role in curb of superinfection; however, these responses are not sufficiently strong to completely prevent superinfection. Thus, a successful HIV-1 vaccine likely needs to induce more potent and broader immune responses than those elicited by primary infection. On the other hand, potent and broad neutralization responses are more often detected after superinfection than during monoinfection. This suggests that broadly neutralizing antibodies are more likely induced by sequential immunization of multiple different immunogens than with only one form of envelope glycoprotein immunogens. Understanding why the protection from superinfection by immunity induced by primary infection is insufficient and if superinfection can lead to cross-reactive immune responses will be highly informative for HIV-1 vaccine design.

利用碱金属离子效应进行PEDOT:PSS 热电性能工程设计 Article

Jingjin Dong, Jian Liu, Xinkai Qiu, Ryan Chiechi, L. Jan Anton Koster, Giuseppe Portale

《工程（英文）》 2021年 第7卷 第5期   页码 647-654 doi: 10.1016/j.eng.2021.02.011

摘要：

聚（3,4-乙烯二氧噻吩）:聚（苯乙烯磺酸）（PEDOT:PSS）的电学性能设计在传感器、热电（TE）发生器和太阳能电池中的空穴传输层等各种应用方面具有巨大的潜力。应用各种策略可实现PEDOT:PSS的最佳电学性能，如碱性溶液后处理。然而，目前尚不清楚碱性溶液后处理引起的结构转变背后的工作机制和确切细节。在本研究中，我们针对三种常见的绿色碱性溶液，即LiOH、NaOH和KOH的后处理效果提出了一项比较研究，利用原子力显微镜、掠入射广角X射线散射、三波段分光光度计光谱和衰减全反射傅里叶变换红外光谱等技术研究了碱性溶液后处理诱导的薄膜结构改变。碱性溶液诱导的结构改变是造成薄膜热电功率因子提高的原因，这取决于所用的碱性溶液。根据碱金属阳离子和PSS链之间的不同亲和力来解释这一结果，这种亲和力决定了PEDOT不同的去掺杂程度。本文的结果阐明了PEDOT:PSS在暴露于高pH值溶液时发生的结构重组，并可激发未来各种应用领域的pH值/离子响应器件的创新灵感。

摘要： 足迹作为刑事侦查的重要证据，能反映地面形貌受细小颗粒分布的影响产生的变化。现有非接触式光学检测方法通过测量足迹与地面光强对比度辨别足迹。引入掠入射照明模式能够增强二者对比度。本文使用普通商用彩色相机对不同类型地面的足迹进行偏振成像。结果表明，在相机镜头前和光源前端放置线偏振片，能有效提高足迹成像对比度，其中水平线偏振对对比度提升效果最为明显。通过相机3个颜色通道检测偏振图像光谱特征，实验结果表明蓝色通道下获得最大对比度。掠入射偏振光成像能有效增强足迹与地面对比度，为刑事侦查中提取足迹提供有力支撑。
