《诗经》邶、鄘、卫三风中的女子既多且美,其体貌之美有概而言之者,有分而述之者。与其他国风相比,这三风表现女性体貌之美注重细部,如对女性的手、额头、眉目、牙齿、颈部、笑靥、头发、步态等精描细绘,体现出细致化的特点。女性以硕为美,是从当时生产和生育的实际需要出发而产生的审美标准,而三风写女性美突出"白"这一特点有殷人尚白遗风的留存。三风中的一些审美标准具有一定的延续性,体现并影响着中华民族的审美意识和审美趣味。

绿色GIr1和红色R-4B磷光染料,采用红绿红、绿红、红绿、绿红绿等顺序,与主体材料CBP共蒸,制备了四种红绿磷光器件,并结合TCTA和BCP对载流子和激子的阻挡作用,研究了发光层掺杂顺序对器件性能的影响。结果表明,四种器件光谱、光效、亮度和发光颜色均有较大差异,且BCP和CBP界面附近是主要的激子复合区。在电压为5v,红绿红掺杂型器件,亮度、电流效率和色坐标分别为40.12cd.m-2,7.68cd.A-1和(0.630 1,0.365 4);而绿红绿掺杂型器件为104cd.m-2,19.75cd.A-1和(0.371 7,0.576 8)。分析认为:CBP与GIr1,R-4B,BCP,TCTA有较大的LUMO能级差异,发光层中电子的主要传输方式为掺杂分子上的俘获和分子间跳跃,不同掺杂顺序会形成不同能级势垒分布,发光层内电荷累积形成的空间电场分布不同。

相对于丝状放电模式,均匀介质阻挡放电(DBD)产生的等离子体功率密度适中,可以对材料表面进行更均匀的处理,在大规模工业应用上具有更为广阔的前景。本文用He和Ne均匀DBD产生的低温等离子体对聚对苯二甲酸乙二酯(PET)薄膜进行表面改性,通过接触角、表面能测量以及ATR-FTIR等手段研究了等离子体处理前后PET的表面特性,从能量密度角度比较了两种气体中均匀DBD处理后PET表面特性的变化规律,并对所得到结果进行分析。结果表明,两种气体均匀DBD改性后,PET薄膜表面水接触角随能量密度的增加而减小,表面能随能量密度的增加而增加,两者均在一定能量密度时达到饱和值;未达到饱和前,在相同能量密度下,Ne均匀DBD改性更迅速,但处理饱和后,两种均匀DBD的改性效果相差不大。因此,选择Ne作为工作气体可以提高生产效率,而选择He作为工作气体可以节约生产成本,两者均能得到良好的改性效果。

Background Sustained hypotension during hemodialysis （HD） is an important clinical issue. Plasma adrenomedullin （AM） is increased in HD patients with sustained hypotension, but little is known about whether removing AM can improve hypotension. The objective of this study was to investigate the beneficial effects of hemodialysis using a high-flux dialyzer on removal of increased plasma AM levels and improving low blood pressure in elderly HD patients with sustained *** Forty-eight elderly patients （age 65 or older） who had undergone maintenance HD for more than one year were recruited and studied. We evaluated plasma levels of AM in sustained hypotension （SH; n=28） and normotensive （NT; n=20） patients. The patients with hypotension were further divided into two subgroups and treated with eitherhigh-flux dialyzer or low-flux dialyzer for 3 months. Plasma adrenomedullin levels and blood pressure were analyzed at days 0 and *** Plasma levels of AM were significantly higher in SH than in NT patients （（24.92±3.7） ng/L vs. （15.52±6.01） ng/L,P〈0.05）, and were inversely correlated with mean arterial blood pressure （MAP） at pre-HD. After 3 months, the level of plasma AM in high-flux group was decreased （（24.58±4.36） ng/L vs. （16.18±5.08） ng/L, P 〈0.05）, but MAP was increased （（67.37±4.31） mmHg vs. （74.79±3.59） mmHg, P〈0.05）. There was no obvious change in low-flux *** Plasma AM levels were significantly elevated in elderly HD patients with SH. High-flux dialyzer therapy can decrease plasma AM level and improve hypotension.

Background In both the seventh edition of the International Union Against Cancer （UICC） staging system for gastric cancer and the 14th edition of the Japanese Gastric Cancer Association （JGCA） system, T4a is defined as ＂Tumor perforates serosa （visceral peritoneum） without invasion of adjacent structures.＂ The aim of this study was to investigate the differences in prognosis between patients with serosa-penetrating and serosa-invading T4aN0M0 gastric carcinomas. Methods Data were collected from 221 patients with T4aNoMo gastric carcinoma who underwent D2 resection at our cancer center between January 1990 and December 2008. The cohort included 42 patients with serosa-penetrating tumors and 179 patients with serosa-invading tumors. The average follow-up time was 85.5 months. Spearman＇s rank correlation, Kaplan-Meier plots, and Cox proportional hazards regression models were used to analyze the data. Results The 5-year survival rate of patients with serosa-penetrating and serosa-invading gastric cancers were 31% and 62% respectively （P 〈0.05）. The relapse rates after D2 radical surgery were 16.2% in patients with serosa-invading gastric cancer versus 59.5% in those with serosa-penetrating tumors （P 〈0.05）. Peritoneal dissemination and distant organ/lymph node metastatic rates were 76.0% and 24.0% respectively in patients with penetrating tumors, versus 44.8% and 55.2% respectively in patients with invading tumors （P 〈0.05）. Multivariate analysis showed that penetration of the serosa was an independent prognostic indicator of overall survival. Conclusions Our findings provide a basis for the concept that serosa-penetrating TaaNoMo gastric carcinoma represents a more aggressive cancer than serosa-invading T4aN0M0 gastric carcinoma. Serosa penetration is an independent factor for poor prognosis of patients with gastric carcinoma.

Background:Hospital environment remains a risk for healthcare-associated infections (HAIs).This was a prospective study to evaluate the comprehensive impact of relocating a neonatal intensive care unit (NICU) to a new facility and improved environmental cleaning practice on the presence of methicillin-resistant Staphylococcus aureus (MRSA) on inanimate surfaces and the incident rate of ***:New environmental cleaning measures were adopted after the NICU was moved to a new and better-designed *** effect of moving and the new environmental cleaning practice was investigated by comparing the positive number of MRSA on ward surfaces and the incidence density of HAIs between the baseline and intervention ***:Only 2.5% of environmental surfaces were positive for MRSA in the intervention period compared to 44.0% in the baseline period (P<0.001).Likewise,the total incident rate of HAIs declined from 16.8 per 1000 cot-days to 10.0 per 1000 cot-days (P<0.001).Conclusion:The comprehensive measures of relocating the NICU to a new facility design with improved environmental cleaning practice are effective and significantly reduce the incidence of HAIs.

J-aggregates of dye molecules are a unique supramolecular structure, which shows great promise in photoelectric devices due to its remarkable optical and transport properties. In this paper, we report the templated formation of J-aggregate nanotubes by the adsorption of 3,3’-diethylthiacarbocyanine iodide on the self-assembled nanotubes of lithocholic acid. The optical and electronic properties of the templated J-aggregate nanotubes are studied. A sensor platform is fabricated by depositing the J-aggregate nanotubes on interdigitated gold electrodes for the detection of dopamine (DA). We find that the current change of the J-aggregate nanotube-based sensor platform in response to DA is linear in the concentration range from 10 nM to 70 nM, giving the detection limit of 0.27 nM.
