Prognostic Value of Preoperative Serum CA 242 in Esophageal Squamous Cell Carcinoma Cases
Feng, Ji-Feng,Huang, Ying,Chen, Qi-Xun Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3
Purpose: Carbohydrate antigen (CA) 242 is inversely related to prognosis in many cancers. However, few data regarding CA 242 in esophageal cancer (EC) are available. The aim of this study was to determine the prognostic value of CA 242 and propose an optimum cut-off point in predicting survival difference in patients with esophageal squamous cell carcinoma (ESCC). Methods: A retrospective analysis was conducted of 192 cases. A receiver operating characteristic (ROC) curve for survival prediction was plotted to verify the optimum cuf-off point. Univariate and multivariate analyses were performed to evaluate prognostic parameters for survival. Results: The positive rate for CA 242 was 7.3% (14/192). The ROC curve for survival prediction gave an optimum cut-off of 2.15 (U/ml). Patients with CA 242 ${\leq}$ 2.15 U/ml had significantly better 5-year survival than patients with CA 242 >2.15 U/ml (45.4% versus 22.6%; P=0.003). Multivariate analysis showed that differentiation (P=0.033), CA 242 (P=0.017), T grade (P=0.004) and N staging (P<0.001) were independent prognostic factors. Conclusions: Preoperative CA 242 is a predictive factor for long-term survival in ESCC, especially in nodal-negative patients. We conclude that 2.15 U/ml may be the optimum cuf-off point for CA 242 in predicting survival in ESCC.

( Chung-feng Huang ),( Pey-fang Wu ),( Ming-lun Yeh ),( Ching-i Huang ),( Po-cheng Liang ),( Cheng-ting Hsu ),( Po-yao Hsu ),( Hung-yin Liu ),( Ying-chou Huang ),( Zu-yau Lin ),( Shinn-cherng Chen ),( 대한간학회 2021 Clinical and Molecular Hepatology(대한간학회지) Vol.27 No.1
Background/Aims: Obstacles exist in facilitating hepatitis C virus (HCV) care cascade. To increase timely and accurate diagnosis, disease awareness and accessibility, in-hospital HCV reflex testing followed by automatic appointments and a late call-back strategy (R.N.A. model) was applied. We aimed to compare the HCV treatment rate of patients treated with this strategy compared to those without. Methods: One hundred and twenty-five anti-HCV seropositive patients who adopted the R.N.A. model in 2020 and another 1,396 controls treated in 2019 were enrolled to compare the gaps in accurate HCV RNA diagnosis to final treatment allocation. Results: The HCV RNA testing rate was significantly higher in patients who received reflex testing than in those without reflex testing (100% vs. 84.8%, P<0.001). When patients were stratified according to the referring outpatient department, a significant improvement in the HCV RNA testing rate was particularly noted in patients from non-hepatology departments (100% vs. 23.3%, P<0.001). The treatment rate in HCV RNA seropositive patients was 83% (83/100) after the adoption of the R.N.A. model, among whom 96.1% and 73.9% of patients were from the hepatology and non-hepatology departments, respectively. Compared to subjects without R.N.A. model application, a significant improvement in the treatment rate was observed for patients from non-hepatology departments (73.9% vs. 27.8%, P=0.001). The application of the R.N.A. model significantly increased the in-hospital HCV treatment uptake from 6.4% to 73.9% for patients from non-hepatology departments (P<0.001). Conclusions: The care cascade increased the treatment uptake and set up a model for enhancing in-hospital HCV elimination. (Clin Mol Hepatol 2021;27:136-143)

Ying Hui,Hao Zeng,Yi Feng,Wenzhou Qin,Peisheng Chen,Lifang Huang,Wenfu Zhong,Liwen Lin,Hui Lv,Xue Qin 한국생물공학회 2021 Biotechnology and Bioprocess Engineering Vol.26 No.3
Purpose: This study aims to explore the differential expression of SFN gene and its regulatory role in different hepatocarcinoma cells, and the impact on hepatocarcinoma. Materials and Methods: High and low SFN expression cells were screened by qRT-PCR and western blotting methods. SFN over expression and interference vectors were constructed. Cell viability was detected by CCK8 kit, cell cycle and apoptosis were detected by flow cytometry. Cell invasion and migration were detected. CCNB1 and CDK1 expression levels were detected by qRT-PCR and Western blotting methods. Results: The high SFN expression BEL7402 cells and the low SFN expression Hep3B cells were screened from Hep3B, HepG2, and BEL7402 cells. The activity of Hep3B cells overexpression vector SFNpcDNA3.1(+) decreased and apoptosis increased, the ratio of G0/G1 decreased and the ratio of S phase increased. The activity of BEL7402 cells transfected with SFN siRNA decreased and apoptosis increased, the ratio of G0/G1 decreased and the ratio of G2/M increased. Interference and overexpression vectors have little effect on the invasion and migration of the two cells. The expression of CDK1 in Hep3B cells decreased significantly, the expression of CDK1 and CCNB1 in BEL7402 cells increased significantly. Conclusions: The differentially expressed SFN gene can regulate the growth of the two hepatocarcinoma cells, high expression of SFN gene can inhibit their growth. The mechanism may be achieved by regulating CCNB1 and CDK1 expression.

The strain rate effects on the interaction between a Mode I matrix crack and an inclined elliptic matrix-inclusion interface under dynamic tensile loadings were investigated numerically, and the results are in agreement with previous experimental data. It is found, for a given material system, that there are the first and the second critical strain rates, by which three kinds of the subsequent crack growth patterns can be classified in turn with the increasing strain rate, namely, the crack deflection, the double crack mode and the perpendicular crack penetration. Moreover, such a crack deflection/penetration behavior is found to be dependent on the relative interfacial strength, the inclined angle and the inclusion size. In addition, it is shown that the so-called strain rate effect on the dynamic strength of granule composites can be induced directly from the structural dynamic response of materials, not be entirely an intrinsic material property.

Objectives. Reactive oxygen species in the stria vascularis (SV) of the cochlea may be involved in the pathogenesis of sen-sorineural hearing loss. However, the effects of oxidative stress on SV endothelial cells (SV-ECs) remain largely un-known, and no feasible in vitro cell culture model exists for the functional study of SV-ECs. Methods. We isolated primary SV-ECs from the SV of neonatal mice. The apoptosis-reducing effects of fibronectin in SV-ECs cultured with serum-free medium were determined using β-galactosidase staining and flow cytometry. SV-ECsincubated in serum-free medium were treated with various H2O2 concentrations to evaluate the effects of H2O2 ontheir viability. The secretome of SV-ECs treated with or without H2O2 (100 μM or 500 μM) was analyzed using high-resolution mass spectrometry. The function of the SV-EC secretome was evaluated by a macrophage assay. Results. We successfully isolated and characterized the SV-ECs. Treatment with H2O2 at concentrations up to 500 μM for2 hours and further incubation with serum-free medium in plates precoated with fibronectin showed no significanteffect on apoptosis. Compared to the control SV-ECs, the amount of differential proteins in the secretome of SV-ECsstimulated with 500 μM H2O2 was much higher than in those treated with 100 μM H2O2. Kyoto Encyclopedia ofGenes and Genomes and Gene Ontology analyses suggested that the proteins differentially expressed in SV-ECstreated with 500 μM H2O2 were involved in the regulation of multiple signaling pathways and cellular processes. Thesecretome of H2O2-stimulated SV-ECs exhibited significant pro-inflammatory effects on macrophages. Conclusion. We successfully established an in vitro serum-free culture method, identified the differential proteins releasedby oxidative stress-induced ECs and their functions, and revealed the pro-inflammatory effects of the secretome ofH2O2-stimulated SV-ECs. Therefore, SV-ECs might elicit immunoregulatory effects on bystander cells in the microen-vironment of oxidative stress-induced cochlea, especially cochlear macrophages.

Baicalin attenuates TNBS-induced colitis in rats by modulating the Th17/Treg paradigm
Ying Zou,Shi-Xue Dai,Hong-Gang Chi,Tao Li,Zhi-Wei He,Jian Wang,Cai-Guo Ye,Guo-Liang Huang,Bing Zhao,Wen-Yang Li,Zheng Wan,Jin-Shan Feng,Xue-Bao Zheng 대한약학회 2015 Archives of Pharmacal Research Vol.38 No.10
Baicalin, a flavonoid, has a wide range ofpharmacological properties, including immunomodulation. The objective of this study was to investigate the effect ofbaicalin on the balance of T helper 17 (Th17) and regulatoryT (Treg) cells in a colitis model. The rat colitis modelwas induced by 2,4,6-trinitrobenzene sulfonic acid(TNBS). Baicalin (10 ml/kg, each) or mesalazine (positivecontrol) was then administered orally for 7 days. Inflammatoryand immunological responses were evaluated bypathology, enzyme-linked immunosorbent assay, real-timepolymerase chain reaction, western blot analysis, and flowcytometry. Our study showed that baicalin not only significantlyattenuated TNBS-induced colitis by reducing thedisease activity index as well as macroscopic and microscopicscores, but it also improved the weight loss andshortening of the colon. Baicalin treatment also induced asignificant decrease in the levels of inflammatory mediators,including the myeloperoxidase activity, the levels oftumor necrosis factor a, IL-1b, and Th1-related cytokinesIL-12 and IFN-c. Furthermore, the beneficial effects ofbaicalin seem to be associated with regulation of the Th17and Treg paradigm. We found that administration ofbaicalin significantly downregulated the number of Th17cells and the levels of Th17-related cytokines (IL-17 andIL-6) and retinoic acid receptor-related orphan receptor ct. In contrast, there was an increase in Treg cells numbers,Treg-related cytokines transforming growth factor-b andIL-10, and forkhead box P3. Our results suggest that theanti-inflammatory effect of baicalin may be linked tomodulation of the balance between Th17 and Treg cells inTNBS-induced ulcerative colitis.

Graphite-based selectorless RRAM: improvable intrinsic nonlinearity for array applications
Chen, Ying-Chen,Hu, Szu-Tung,Lin, Chih-Yang,Fowler, Burt,Huang, Hui-Chun,Lin, Chao-Cheng,Kim, Sungjun,Chang, Yao-Feng,Lee, Jack C. The Royal Society of Chemistry 2018 Nanoscale Vol.10 No.33
<P>Selectorless graphite-based resistive random-access memory (RRAM) has been demonstrated by utilizing the intrinsic nonlinear resistive switching (RS) characteristics, without an additional selector or transistor for low-power RRAM array application. The low effective dielectric constant value (<I>k</I>) layer of graphite or graphite oxide is utilized, which is beneficial in suppressing sneak-path currents in the crossbar RRAM array. The tail-bits with low nonlinearity can be manipulated by the positive voltage pulse, which in turn can alleviate variability and reliability issues. Our results provide additional insights for built-in nonlinearity in 1<I>R</I>-only selectorless RRAMs, which are applicable to the low-power memory array, ultrahigh density storage, and in-memory neuromorphic computational configurations.</P>
