目前can总线通讯已经在工业控制系统中得到了广泛的应用。虽然can底层通讯架构已经使其具备了高可靠性和强实时性,但是应用层设计是否合理也对交互双方通讯可靠性有至关重要的影响。首先提出了一种交互握手式通讯机制以及一种以包含消息序号、指令码及确认标识为特点的协议设计方法。然后依据协议特点进行了基于配置文件的指令交互软件设计。最后,基于QT进行了软件实现。经工程验证,提出的协议设计及软件实现方法,不仅具有扩展性好、灵活可配置的优点,而且在应用层进一步提高了can交互通讯的可靠性。

Colorectal anastomotic leakage is a serious complication of colorectal surgery, leading to high morbidity and mortality rates. In recent decades, many strategies aimed at lowering the incidence of anastomotic leakage have been examined. The focus of this review will be on mechanical aids protecting the colonic anastomosis against leakage. A literature search was performed using MEDLINE, EMBASE, and The Cochrane Collaborative library for all papers related to prevention of anastomotic leakage by placement of a device in the colon. Devices were categorised as decompression devices, intracolonic devices, and biodegradable devices. A decompression device functions by keeping the anal sphincter open, thereby lowering the intraluminal pressure and lowering the pressure on the anastomosis. Intracolonic devices do not prevent the formation of dehiscence. However, they prevent the faecal load from contacting the anastomotic site, thereby preventing leakage of faeces into the peritoneal cavity. Many attempts have been made to find a device that decreases the incidence of AL;however, to date, none of the devices have been widely accepted.

There are large knowledge gaps regarding how to control stem cells growth and differentiation.The limitations of currently available technologies,such as growth factors and/or gene therapies has led to the search of alternatives.We explore here how a cell’s epigenome influences determination of cell type,and potential applications in tissue engineering.A prevalent epigenetic modification is the acetylation of DNA core histone proteins.Acetylation levels heavily influence gene transcription.Histone deacetylase (HDAC) enzymes can remove these acetyl groups,leading to the formation of a condensed and more transcriptionally silenced chromatin.Histone deacetylase inhibitors (HDACis) can inhibit these enzymes,resulting in the increased acetylation of histones,thereby affecting gene expression.There is strong evidence to suggest that HDACis can be utilised in stem cell therapies and tissue engineering,potentially providing novel tools to control stem cell fate.This review introduces the structure/function of HDAC enzymes and their links to different tissue types (specifically bone,cardiac,neural tissues),including the history,current status and future perspectives of using HDACis for stem cell research and tissue engineering,with particular attention paid to how different HDAC isoforms may be integral to this field.

Convergence of roof and floor in underground mine openings is a common occurrence. This convergence not only adversely affects the ability of workers, equipment and supplies to travel through the mine, it also reduces the effectiveness of the mine ventilation system, which is essential for the dilution of methane gas and airborne respirable dust. While installing secondary standing supports to control floor and roof convergence, such supports, by nature, partially obstruct a portion of the airway. These added obstructions inhibit the ability of the ventilation system to operate as efficiently as it could by increasing the resistance in and reducing the cross-sectional area of the airway. This study introduces and demonstrates the benefits of The Eye can^(TM) standing roof support, which controls floor and roof convergence and is less obstructive to air flow than conventional wooden cribs. Laboratory findings show that the normal resistance of a supported lined airway is reduced by using this new product from Burrell Mining Products, Inc., while providing the same roof support characteristics of an established product—The canò. Load vs. displacement curves generated from laboratory tests demonstrated that this new product behaves with the same roof support characteristics as others in The can product family. Ventilation data gathered from a simulated mine entry was then used for computational fluid dynamics(CFD) modeling.The CFD analysis showed an improvement with The Eye can vs. other accepted forms of standing roof support. This proof-of-concept study suggests that, when using this new product made by Burrell Mining Products, Inc., not only will the convergence from the roof and floor be controlled, but airway resistance will also be reduced.

Our previous study found that plate factor-4 variant (CXCL4L1) was downregulated in the serum of patients with prostate cancer (PCa). The aim of the present study was to investigate the prognostic value of CXCL4L1 in PCa. In total, 213 PCa patients treated with radical prostatectomy were enrolled and peripheral blood samples of all patients were collected. Expression of serum CXCL4L1 in patients with different tumor stages and grades were measured by enzyme-linked immunosorbent assay (ELISA). The Kaplan-Meier method was applied to estimate the progression to castration-resistant prostate cancer (CRPC), metastasis, biochemical recurrenee (BCR)-free survival, and overall survival (OS). Prog no stic factors for BCR-free survival and OS were determi ned by univariate and multivariate analyses using the Cox proportional hazards regression model. The expression of CXCL4L1 was significantly lower in PCa patie nts with adva need pathological tumor stage, high-grade Gleason score, and metastasis. Moreover, down regulation of CXCL4L1 not only strongly correlated with aggressive clinicopathological features, but also predicted tumor progress!on and unfavorable outcomes. Finally, multivariate Cox regression analyses identified CXCL4L1 as an independent prognostic factor for both BCR-free survival (hazard ratio [HR]: 2.03, 95% confidence interval [Cl]: 1.26-3.27;P = 0.004) and OS (HR: 2.26, 95% Cl: 1.07-4.79;P= 0.033). In con elusion, our results in dicate that CXCL4L1 might serve as a no vel and promising prog no stic biomarker for patients with PCa and potential therapeutic target in the future.
