AIM To elucidate the prevalence and risk of mortality of nonalcoholic liver cirrhosis(LC) patients with coronary artery disease(CAD).METHODS The study cohort included newly diagnosed nonalcoholic LC patients age ≥ 40 years old without a diagnosis of CAD from 2006 until 2011 from a longitudinal health insurance database. The mean follow-up period for the study cohort was 1152 ± 633 d. The control cohort was matched by sex, age, residence, and index date. Hazard ratios(HRs) were calculated using the Cox proportional hazard model and the Kaplan-Meier method. RESULTS After exclusion, a total of 3409 newly diagnosed nonalcoholic cirrhotic patients were identified from one million samples from the health insurance database. We found that CAD(5.1% vs 17.4%) and hyperlipidemia(20.6% vs 24.1%) were less prevalent in nonalcoholic LC patients than in normal subjects(all P < 0.001), whereas other comorbidities exhibited an increased prevalence. Among the comorbidities, chronic kidney disease exhibited the highest risk for mortality(adjusted HR(AHR) = 1.76; 95%CI: 1.55-2.00, P < 0.001). Ascites or peritonitis exhibited the highest risk of mortality among nonalcoholic cirrhotic patients(AHR = 2.34; 95%CI: 2.06-2.65, P < 0.001). Finally, a total of 170 patients developed CAD after a diagnosis of nonalcoholic LC. The AHR of CAD in nonalcoholic LC patients was 0.56(95%CI: 0.43-0.74, P < 0.001). The six-year survival rates for nonalcoholic LC patients with and without CAD were 52% and 50%, respectively(P = 0.012). CONCLUSION We conclude that CAD was less prevalent and associated with a reduced risk of mortality in nonalcoholic cirrhotic patients.

This work proposes two fault tolerant quantum secure direct communication （QSDC） protocols which are robust against two kinds of collective noises： the collective-dephasing noises and the collective-rotation noises, respectively. The two QSDC protocols are constructed from four-qubit DF states which consist of two logical qubits. The receiver simply performs two Bell state measurements （rather than four-qubit joint measurements） to obtain the secret message. The protocols have qubit efficiency twice that of the other corresponding fault tolerant QSDC protocols. Furthermore, the proposed protocols are free from Trojan horse attacks.

In this study, we extend our previous adaptive steganographic algorithm to support point geometry. For the purpose of the vertex decimation process presented in the previous work, the neighboring information between points is necessary. Therefore, a nearest neighbors search scheme, considering the local complexity of the processing point, is used to determinate the neighbors for each point in a point geometry. With the constructed virtual connectivity, the secret message can be embedded successfully after the vertex decimation and data embedding processes. The experimental results show that the proposed algorithm can preserve the advantages of previous work, including higher estimation accuracy, high embedding capacity, acceptable model distortion, and robustness against similarity transformation attacks. Most importantly, this work is the first 3D steganographic algorithm for point geometry with adaptation.

AIM To investigate the association between a recent gastrointestinal(GI) endoscopy and the subsequent risk of pyogenic liver abscess(PLA).METHODS We designed a nested case control study. Using the Taiwan National Health Insurance Research Database, 2135 patients with a first diagnosis of PLA were identified from 1998 to 2011. Another 10675 patients without PLA matched by age and sex were selected as reference controls. We identified and compared the possible risk factors for PLA and GI endoscopies performed before the index date(when PLA was diagnosed) between the two cohorts. Multivariate analysis was conducted to examine the risk of PLA within the 90 d after the GI *** Patients with a history of diabetes [adjusted odds ratio(a OR) = 4.92, 95%CI: 1.78-13.61], end-stage renal disease(a OR = 3.98, 95%CI: 1.45-10.91), biliary tract infection(a OR = 2.68, 95%CI: 2.11-3.40), liver cirrhosis(a OR = 2.19, 95%CI: 1.39-3.46), GI malignancies(a OR = 5.68, 95%CI: 4.23-7.64), appendicitis(a OR = 3.16, 95%CI: 2.27-4.41), diverticulitis(a OR = 1.64, 95%CI: 1.01-2.64), and recent endoscopic retrograde cholangiopancreatography(a OR = 27.04, 95%CI: 11.65-62.72) were significantly associated with an increased risk of PLA. After adjusting for the above risk factors and the frequency of outpatient department visits and abdominal ultrasounds during 90 d before the index date, an upper GI panendoscopy(a OR = 2.75, 95%CI: 2.05-3.69) but not a lower GI endoscopy(a OR = 1.07, 95%CI: 0.62-1.86) was significantly associated with *** An upper GI panendoscopy performed before 90 d may increase the risk of PLA.

This article studies the transient heat conduction in a slab when passing through various sections of the furnace, and focuses on the thickness of the scale layer formed on the slab. The transient heat conduction behavior of a slab in various sections of the heating furnace is analyzed using the Laplace transformation method, including the pre-heating zone, the first heating zone, the second heating zone, and the soaking zone. The heating pattern of the furnace is then modified to reduce fuel consumption. The simulation results show that the scale layer formed on the slab significantly influences the quality of the hot rolled coil formed, and how the furnace parameters affect the efficiency of the furnace and the quality of the coil.

中性氢(HI)气体是恒星形成的基本物质,驱动着星系的演化。对于星暴矮星系NGC 5253,过去的研究利用射电干涉阵观测到的HI气体呈不对称分布,向东北方向延伸约7 kpc。这一延展结构可能表明NGC 5253与其附近的旋涡星系M 83之间存在动力学联系。为研究这两个星系之间可能存在的HI气体连接,从绿岸望远镜获得了射电L波段对NGC 5253周围的HI成图数据,探测到NGC 5253和M 83之间可能存在的7个HI气体云团。这些HI气体云团候选体主要分布在东北方向,由NGC 5253延展至距离超过60 kpc外。这些气体云团可能在触发矮星系NGC 5253剧烈的恒星形成活动中发挥重要作用。
