Objective:To investigate the protective effect of Dahuang Fuzi Decoction(DHFZD),a traditional Chinese prescription,at alleviating sepsis-induced inflammation and gut barrier damage in rats.Methods:Forty clean-grade male Sprague-Dawley rats were divided randomly into three groups:normal control group(NCG,n?10),model control group(MCG,n?15)and DHFZD-treated group(DHFZDG,n?15).NCG rats were sham operated on and used as the controls,whereas MCG and DHFZDG rats were used to replicate the rat sepsis model using cecal ligation and puncture(CLP).The DHFZDG rats received DHFZD by gavage(4.5 mg/g of body weight)2 h prior to CLP and after its successful induction,while the NCG and MCG rats received equivalent amounts of sterilized water by gavage.All rat groups were starved and had free access to water.At 24 h post-experimental set up,the mortality of rats in each group was recorded,and peritoneal inflammation assessment and pathological changes related to the intestinal mucosal injury index(IMII)in the surviving rats were evaluated.D-lactic acid,tumor necrosis factor(TNF)-a,interleukin(IL)-6 and IL-10 peripheral blood concentrations,along with secretory immunoglobulin A(sIgA)in the intestinal mucosa were evaluated by enzyme-linked immunosorbent assays.Gut microbes were detected using 16S rRNA gene sequencing.Results:DHFZD reduced sepsis-related mortality in the rats.Moreover,it alleviated peritoneal inflammation and pathological changes according to the IMII.DHFZD reduced serum procalcitonin,TNF-a and IL-6 concentrations,but not the IL-10 concentration.It also reduced serum D-lactic acid and increased sIgA concentrations in intestinal mucosa.Notably,DHFZDG restored gut microbiota diversity and regulated the decrease in Bacteroidetes induced by sepsis,compared with the MCG rats.Conclusion:DHFZDG may play a protective role in sepsis by alleviating sepsis-induced inflammation and gut barrier damage in rats. 展开更多

The performance degradation and even damage of the e-textiles caused by sweat,water,or submersion during all-weather health monitoring are the main reasons that e-textiles have not been commercialized and routinized so far.Herein,we developed an amphibious,high-performance,air-permeable,and comfortable all-textile triboelectric sensor for continuous and precise measurement of epidermal pulse waves during full-day activities.Based on the principle of preparing gas by acid-base neutralization reaction,a one-piece preparation process of amphibious conductive yarn(ACY)with densely porous structures is proposed.An innovative three-dimensional(3D)interlocking fabric knitted from ACYs(0.6 mm in diameter)and polytetrafluoroethylene yarns exhibit high sensitivity(0.433 V·kPa^(-1)),wide bandwidth(up to 10 Hz),and stability(>30,000 cycles).With these benefits,98.8%agreement was achieved between wrist pulse waves acquired by the sensor and a high-precision laser vibrometer.Furthermore,the polytetrafluoroethylene yarn with good compression resilience provides sufficient mechanical support for the contact separation of the ACYs.Meanwhile,the unique skeletonized design of the 3D interlocking structure can effectively relieve the water pressure on the sensor surface to obtain stable and accurate pulse waves(underwater depth of 5 cm).This achievement represents an important step in improving the practicality of e-textiles and early diagnosis of cardiovascular diseases. 展开更多

Central nervous system(CNS)tumors represent the most deadly cancer in pediatric age group.In China,thousands of children are diagnosed with CNS tumors every year.Despite the improving socioeconomic status and availability of medical expertise within the country,unique challenges remain for the delivery of pediatric neuro-oncology service.In this review,we discuss the existing hurdles for improving the outcome of children with CNS tumors in China.Need for precise disease burden estimation,lack of intra-and inter-hospital collaborative networks,high probability of treatment abandonment,along with financial toxicities from treatment represent the key challenges that Chinese healthcare providers encounter.The tremendous opportunities for advancing the status of pediatric neuro-oncology care in and beyond the country are explored. 展开更多

Entity resolution is a key aspect in data quality and data integration, identifying which records correspond to the same real world entity in data sources. Many existing ap- proaches require manually designed match rules to solve the problem, which always needs domain knowledge and is time consuming. We propose a novel genetic algorithm based en- tity resolution approach via active learning. It is able to learn effective match rules by logically combining several different attributes' comparisons with proper thresholds. We use ac- tive learning to reduce manually labeled data and speed up the learning process. The extensive evaluation shows that the proposed approach outperforms the sate-of-the-art entity res- olution approaches in accuracy. 展开更多

Flexible high-frequency vibration sensors are highly desirable in various real-world applications such as structural health monitoring,environmental monitoring,and the internet of things.However,developing a facile and effective method to fabricate vibration sensors simultaneously featuring high vibration frequency response-ability and flexibility remains a grand challenge.Herein,we report a flexible ultrahigh-frequency triboelectric vibration sensor(UTVS)prepared by a layer-particle-layer structure.Owing to the flexibility of the materials(i.e.,polyethylene terephthalate membrane)and the ultrahigh-frequency vibration response-ability of internal microparticles,the flexible UTVS exhibits an enhanced working frequency range of 3–170 kHz,which is much broader than previously reported triboelectric vibration sensors.Moreover,the UTVS can work not only in a flat state but also in a bent state due to its flexibility and the unique layer-particle-layer structural design.The UTVS shows nanometer-level vibration response-ability,omnidirectional response,stability in the temperature range of 10–70°C,good frequency resolution of 0.01 kHz,and excellent performance in burst vibration detection(e.g.,pencil lead break events and impact events from falling steel balls).With a collection of compelling features,the device is successfully demonstrated in vibration monitoring of curved structures(e.g.,real-time water pipeline leak monitoring).Such a flexible ultrahigh-frequency triboelectric vibration sensor holds great potential in a wide range of practical applications,such as communication,health care,and infrastructure monitoring. 展开更多
