Abstract
目的 研究GLIDE(吉西他滨、门冬酰胺酶、异环磷酰胺、地塞米松、依托泊苷)方案治疗初发进展期及复发难治性结外鼻型NK/T细胞淋巴瘤(ENKL)患者的有效性及安全性。 方法 纳入2010年3月至2016年3月收治的初发进展期及复发难治性ENKL患者42例,给予GLIDE方案化疗,中位疗程数为3(2~6)个,评估化疗结束后缓解率及早期(2个疗程后)缓解率,采用Kaplan-Meier方法统计无进展生存(PFS)及总生存(OS),同时采用Cox回归方法进行多因素分析,寻找影响患者PFS及OS的独立预后因素。 结果 31例(73.8%)患者达到完全缓解(CR),其中22例(52.4%)为早期CR,31例CR患者中14例接受序贯自体造血干细胞移植(ASCT)。1年PFS与OS率分别为65.6%和82.7%,4年PFS与OS率分别为48.2%和63.1%,中位OS时间未达到,中位PFS时间为30.5个月。多因素分析提示美国东部肿瘤协作组体能状态评分(ECOG评分)0~1分以及CR后序贯ASCT为减少复发、延长患者生存的有利因素。 结论 GLIDE方案能够有效治疗初发进展期及复发难治性ENKL, ECOG评分0~1分及CR后序贯ASCT治疗是患者获得较长PFS和OS时间的独立预后因素。

Abstract
OBJECTIVE The aim of this study was to investigate the effect of basal ganglia lesion of Wilson's disease (WD) patients on event-based prospective memory (EBPM) and time-based prospective memory (TBPM). PATIENTS AND METHODS A total of 30 WD patients and 30 age and education level matched healthy controls were included. EBPM (an action whenever particular words were presented) and TBPM (an action at certain times) were performed to test the involvement of the prospective memory in WD. RESULTS A significant difference was found in the performance of TBPM (2.9±1.1 vs. 5.8±0.4, p<0.05), but not EBPM (5.4±0.7 vs. 5.5±0.7, p>0.05) in patients with WD compared with the healthy controls. CONCLUSIONS Our results demonstrated that basal ganglia are involved in the prospective memory in patients with WD.

Abstract
This work reports on integrated passive-flow optical microfluidic devices to detect waterborne pathogens in the field. Ring-shaped organic photodiodes were integrated to a capillary-induced flow microfluidic channel for monitoring chemiluminescent sandwich immunoassays enhanced by gold nanoparticles. The integrated device yielded a resolution of 4×10(4) cells/mL for the detection of Legionella pneumophila, which represented a 25-fold improvement over chemiluminescence detection devices employing no gold-nanoparticle enhancement. This work demonstrates the feasibility of a low-cost but highly sensitive lab-on-a-chip device amenable for point-of-use applications.

Abstract
Cyclic GMP-AMP synthase (cGAS) detects cytosolic DNA during virus infection and induces an antiviral state. cGAS signals by synthesis of a second messenger, cyclic GMP-AMP (cGAMP), which activates stimulator of interferon genes (STING). We show that cGAMP is incorporated into viral particles, including lentivirus and herpesvirus virions, when these are produced in cGAS-expressing cells. Virions transferred cGAMP to newly infected cells and triggered a STING-dependent antiviral program. These effects were independent of exosomes and viral nucleic acids. Our results reveal a way by which a signal for innate immunity is transferred between cells, potentially accelerating and broadening antiviral responses. Moreover, infection of dendritic cells with cGAMP-loaded lentiviruses enhanced their activation. Loading viral vectors with cGAMP therefore holds promise for vaccine development.

Abstract
A typical office layout with cubicles, in which occupants have their own control of the micro-environment by adjusting supply air flow rate of the floor diffuser, is numerically investigated for the impact of the discrepancy in personal thermal sensation preference on thermal comfort. The comparison among different scenarios indicates that whether the local thermal comfort is significantly affected by the neighboring cubicle (coupling effect) depends on whether the doorway is closed or not whereas the "openness", of upper space has no influence on such coupling effect but observably on the thermal comfort. The effect of thermoregulation is also presented and compared with conventional constant heat flux assumption for the occupants.

Abstract
A synthetic optimization of Pelton air turbine in dental handpieces concerning the power output, compressed air consumption and rotation speed in the mean time is implemented by employing a standard design procedure and variable limitation from practical dentistry. The Pareto optimal solution sets acquired by using the Normalized Normal Constraint method are mainly comprised of two piecewise continuous parts. On the Pareto frontier, the supply air stagnation pressure stalls at the lower boundary of the design space, the rotation speed is a constant value within the recommended range from literature, the blade tip clearance insensitive to while the nozzle radius increases with power output and mass flow rate of compressed air to which the residual geometric dimensions are showing an opposite trend within their respective "pieces" compared to the nozzle radius.

Abstract
We present the optical conductivity spectra for the newly discovered cubic perovskite structure BaOsO3 at various temperatures. The compound exhibits metallic behaviour above 50 K, but becomes non-metallic below 50 K. However, below 550 cm(-1), neither the typical Drude response nor an energy gap is observed in optical conductivity spectra from 300 K to 10 K. A broad peak centred at about 550 cm(-1) is observed in the real part of optical conductivity σ1(ω). The structure could be well reproduced by the localization modified Drude model. The life time of the carrier, deduced from σ1(ω) in terms of the localization modified Drude model, decreases with T varying from 300 K to 100 K, then increases slightly at 10 K. The study indicates that the compound is at the boundary of metal-insulator transition.

Abstract
A highly sensitive chemiluminescent immunoassay (CLIA) using a sensitive organic photodetector was developed to detect human cortisol, an important biomarker for stress-related diseases. The developed CLIA was performed onto gold-coated glass chips, on which anti-cortisol antibodies were immobilised and chemiluminescent horseradish peroxidase-luminol-peroxide reactions were generated. Using cortisol-spiked artificial saliva samples, the CLIA biosensor showed a linear range of detection between 0.1 ng/mL and 175 ng/mL and a detection limit of 80 pg/mL. The sensor response was highly specific to cortisol and did not vary significantly between assays. The results indicate the potential clinical application of the CLIA sensor. Furthermore, the simple layered structure of the organic photodetector may encourage the realisation of integrated optical biosensors for point-of-use measurement of salivary cortisol levels.
