This study was designed to explore the prognostic and diagnostic value of Sex-Determining Region Y-Box 9 (SOX9) in cirrhotic hepatocellular carcinoma HCC (CHCC) and noncirrhotic hepatocellular ...carcinoma (NCHCC).
SOX9 tissue expression was detected using data from The Cancer Genome Atlas (TCGA) database and our cohort. The Kaplan-Meier method was used to analyze differences in survival between high/low SOX9 expression groups. Univariate analysis and multivariate analysis were used to identify independent risk factors associated with overall survival (OS). Receiver operating characteristic (ROC) curve and area under the curve (AUC) were utilized for evaluation of the diagnostic efficacy of SOX9.
SOX9 was found to exhibit differential expression between HCC and adjacent normal tissues but not between CHCC and NCHCC, which was confirmed by RNA sequencing, quantitative real-time polymerase chain reaction and immunohistochemical staining. Kaplan-Meier survival analysis and multivariate analysis revealed that high SOX9 expression was closely related to the OS in NCHCC but not that in CHCC. In CHCC and NCHCC, SOX9 expression was positively associated with serum α-fetoprotein levels. The AUC of SOX9 in differentiating HCC and adjacent normal tissues in CHCC and NCHCC was 0.77 and 0.78, respectively, and no significant difference was found between them.
High SOX9 expression may aid prognostic evaluation in NCHCC but not in CHCC. SOX9 expression was not different between CHCC and NCHCC, but it has reliable and comparable diagnostic value in both CHCC and NCHCC.

Most of the existing watermarking and encryption schemes are difficult to ensure the commutativity of watermarking and encryption as well as the visual quality of the protected image.These schemes ...complete watermark embedding and image encryption processes in a fixed order, and they modify the protected image content more or less.Few of them complete the commutativity of watermarking and encryption process without affecting the quality of the protected image content.Therefore, a homomorphic and commutative fragile zero-watermarking based on SVD（singular value decomposition） is proposed.At the sender side, the content owner adopts homomorphic modular encryption to encrypt the original image content, and the two stages of image encryption and watermarking generation do not affect each other.The zero-watermarking information can be generated from the encrypted image and the original host image, respectively.At the receiver end, the legitimate receiver first decrypts the image and then performs watermarking detec
Dispersive solid-phase extraction (DSPE) cleanup combined with accelerated solvent extraction (ASE) is described here as a new approach for the extraction of carbamate pesticides in Radix ...Glycyrrhizae samples prior to UPLC-MS-MS. In the DSPE-ASE method, 15 carbamate pesticides were extracted from Radix Glycyrrhizae samples with acetonitrile by the ASE method at 60°C with a 5 min heating time and two static cycles. Cleanup of a 1 mL aliquot of the extract by the DSPE method used 20 mg PSA (primary secondary amine), 50 mg Al2O3-N, and 20 mg GCB (graphitized carbon black) (as cleanup sorbents) under the determined optimum conditions. The linearity of the method was in the range of 10 to 200 ng/mL with correlation coefficients (r2) of more than 0.996. The limits of detection were approximately 0.2 to 5.0 µg/kg. The method was successfully used for the analysis of target pesticides in Radix Glycyrrhizae samples. The recoveries of the carbamate pesticides at the spiking levels of 50, 100, and 200 µg/kg ranged from 79.7% to 99.3% with relative standard deviations lower than 10%. This multi-residue analytical method allows for a rapid, efficient, sensitive and reliable determination of target pesticides in Radix Glycyrrhizae and other medicinal herbs.
We experimentally present an acoustic metasurface (AMS) with sub-wavelength thickness based on the meta-molecule consisting of eight different sized double-split hollow spheres (DSHSs). By designing ...the discontinuous phase profile covered 2π span induced by the DSHSs, the AMS can manipulate the reflected acoustic waves in a way that could not be imitated by natural materials. Both simulations and experiments show that the AMS can realize anomalous reflection, i.e., a normal incident wave can be reflected into an oblique direction. Moreover, the reflection angle can be flexible controlled by mechanically tuning the spatial distance of the DSHSs in the AMS, which is consistent with the generalized Snell׳s law.

Al-PTFE (aluminum-polytetrafluoroethylene) serves as one among the most promising reactive materials (RMs). In this work, six types of Al-PTFE composites with different Al particle sizes (i.e., 50 ...nm, 1∼2 μm, 6∼7 μm, 12∼14 μm, 22∼24 μm, and 32∼34 μm) were prepared, and quasistatic compression and drop weight tests were conducted to characterize the mechanical properties and reaction characteristics of Al-PTFE composites. The reaction phenomenon and stress-strain curves were recorded by a high-speed camera and universal testing machine. The microstructure of selected specimens was anatomized through adopting a scanning electron microscope (SEM) to correlate the mesoscale structural characteristics to their macroproperties. As the results indicated, in the case of quasistatic compression, the strength of the composites was decreased (the yield strength falling from 22.7 MPa to 13.6 MPa and the hardening modulus declining from 33.3 MPa to 25 MPa) with the increase of the Al particle size. The toughness rose firstly and subsequently decreased and peaked as 116.42 MJ/m3 at 6∼7 μm. The reaction phenomenon occurred only in composites with the Al particle size less than 10 μm. In drop weight tests, six types of specimens were overall reacted. As the Al particle size rose, the ignition energy of the composites enhanced and the composites turned out to be more insensitive to reaction. In a lower strain rate range (10−2·s−1∼102·s−1), Al-PTFE specimens take on different mechanical properties and reaction characteristics in the case of different strain rates. The formation of circumferential open cracks is deemed as a prerequisite for Al-PTFE specimens to go through a reaction.
•E. coli-secreted LPS has a crucial role in mediating the recurrence of chronic proliferative cholangitis and hepatolithiasis.•Biliary administration of antibiotics inhibits chronic proliferative ...cholangitis and stones formation by decreasing the release of LPS-induced proinflammatory and profibrotic cytokines.
The gram-negative bacteria secreted endotoxin, Lipopolysaccharide (LPS), plays important roles in the formation and recurrence of hepatolithiasis and chronic biliary inflammation in patients of Southeast Asia. We aimed to elucidate the anti-inflammatory effect and mechanism of local antibiotics irrigation on chronic proliferative cholangitis (CPC) and hepatolithiasis.
Escherichia coli was injected into rabbit bile ducts to induce CPC. Rabbits were divided into sham operation (SO), povidone-iodine, Metronidazole plus chlorhexidine, ofloxacin, furacillin, Neosporin® G.U., and CPC groups. Local irrigation was performed for 28 days after CPC was established. Residual E. coli and LPS, and the expression of MCP-1, CD14, COX-2, VEGF, IL-6, NF-κB, TNF-α, Fas, TGF-β1, α-SMA, Collagen-I, β-glucuronidase, PKC, C-myc, and Mucin 5AC were assessed in bile duct tissues.
The residual E. coli and LPS, and expression of MCP-1, CD14, COX-2, IL-6, NF-κB, TNF-α, Fas, TGF-β1, α-SMA, β-glucuronidase, PKC, C-myc, and Mucin 5AC in the SO, povidone-iodine, Metronidazole plus chlorhexidine, ofloxacin, and Neosporin® G.U. groups were significantly lower than those in the furacillin and CPC groups (P<0.05). VEGF and Collagen-I levels in the SO, povidone-iodine, metronidazole plus chlorhexidine, and ofloxacin groups were significantly lower than those in the furacillin, Neosporin® G.U., and CPC groups (P<0.05).
LPS affects the pathophysiology of E. coli caused chronic proliferative cholangitis and hepatolithiasis recurrence. Local antibiotics irrigation could prevent chronic proliferative cholangitis and stones formation by decreasing LPS-induced proinflammatory and profibrotic cytokines release. Povidone iodine, metronidazole plus chlorhexidine, and ofloxacin were more effective than Neosporin® G.U. and furacillin.
Soybean seed storage protein is one of the most important plant vegetable proteins, and β subunit is of great signiifcance to enhance soybean protein quality and processing property. F2 segregated ...population and residual heterozygous lines (RHL) derived from the cross between Yangyandou (low level of β subunit) and Zhonghuang 13 (normal level of β subunit) were used for mapping of β subunit content. Our results showed that β subunit content was controlled by a single dominant locus,qBSC-1(β subunit content), which was mapped to a region of 11.9 cM on chromosome 20 in F2 population of 85 individuals. This region was narrowed down to 2.5 cM between BARCSOYSSR_20_0997 and BARCSOYSSR_20_0910 in RHL with a larger population size of 246 individuals. There were 48 predicted genes withinqBSC-1 region based on the reference genome (Glyma 1.0, Williams 82), including the two copies of β subunit coding geneCG4. An InDel marker developed from a thymine (TT) insertion in one copy ofCG4promoter region in Yangyandou cosegregrated with BARCSOYSSR_20_0975 withinqBSC-1 region, suggesting that this InDel marker maybe useful for marker-assisted selection (MAS).
Hepatic epithelioid hemangioendothelioma (HEHE) is an extremely rare malignancy of vascular origin. When most patients with HEHE are diagnosed, they have a diffuse nodular phenotype, which is usually ...unresectable. A single nodular phenotype is found in only a small proportion (13%) of patients, and most are reported to be located in the right lobe of the liver. Although the prognosis of HEHE is considered more favorable than that of other hepatic malignant tumors, the 5-year survival rate is reported to be 64% after treatment. Herein, we present an unusual case of resectable HEHE of a single nodular type in the left lobe of the liver. The patient survived 15 years without recurrence after the multimodal treatment of radical resection and postoperative chemotherapy with thalidomide. The aim of the present study is to emphasize that multimodal treatment of radical resection followed by chemotherapy with thalidomide may achieve a relatively good survival outcome in patients with resectable HEHE of a single nodular type.
