Purpose: We compared the clinical outcomes of modified procedures for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) based on a risk-reduced strategy with those of classic ALPPS procedures in treating large liver carcinoma. Materials and Methods: Short-term outcomes, increases in future liver remnant (FLR) and functional FLR (FFLR), and overall survival (OS) were compared between 45 consecutive patients treated with modified ALPPS procedures and 34 patients treated with classic ALPPS procedures. Results: Clinical outcomes after the 1st-stage operation markedly improved with the modified procedures. Although the proportions of liver cirrhosis and hepatocellular carcinoma were higher in the modified group, the mortality and incidence of severe complications did not increase. FLR and FFLR hypertrophy at 1 week after the 1st-stage operation were similar in both groups; however, kinetic growth rates in the modified group were lower. OS rates were similar. Conclusion: Modified ALPPS procedures could be safely applied to provide long-term survival for patients with liver cirrhosis without sufficient FLR.

<P><B>Abstract</B></P><P>We compare the electronic structure of a quinonoid zwitterionic type molecule adsorbed on both gold and graphene on copper substrates. This (6<I>Z</I>)-4-(butylamino)-6-(butyliminio)-3-oxocyclohexa-1,4-dien-1-olate, C<SUB>6</SUB>H<SUB>2</SUB>(⋯_NHR)<SUB>2</SUB>(⋯_O)<SUB>2</SUB> where R=<I>n-</I>C<SUB>4</SUB>H<SUB>9</SUB>, film is made of small molecules with a large intrinsic dipole of 10Debyes. We find that the photoemission and inverse photoemission final states are well screened for these dipolar molecules on gold. This is not observed when they are adsorbed on graphene on copper. This weaker screening results in a larger highest occupied molecular orbital to lowest unoccupied molecular orbital gap for the molecules on graphene.</P>

Kong-Fang Wei,Zhi-Guang Wang,Jie Gou,Yan-Bin Sheng,Gen-Ming Jin,Hang Zang,Cun-Feng Yao,Yi-Zhun Ma,Tie-Long Shen 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.6

Multilayers with a structure of Si/[Fe(10 nm)/Cu(10 nm)]5 were deposited on Si(100) substrates and then irradiated at room temperature by using 2-MeV Xe20+. The modifications of the multilayers were characterized using a depth profile analysis of the Auger electron spectroscopy (AES) data and the evolution of crystallite structures of the multilayers were analyzed by using X-ray diffraction (XRD). The AES depth profiles indicated that de-mixing of the Fe and the Cu layers was observed at low ion fluences, but inter-mixing of the Fe and the Cu layers was found at high ion fluences and destroyed the layered structure of the multilayers. The obtained XRD patterns showed that, after irradiation by 2-MeV Xe20+ at 2 × 1016 ions/cm2, the peaks of the multilayers related to a Cu-based fcc solid solution and an Fe-based bcc solid solution phase became visible, which implied that the inter-mixing at the Fe/Cu interface resulted in the formation of new phases. A possible mechanism of modification in the Fe/Cu multilayers induced by ion irradiation is briefly discussed.

Kong, Feng,Han, Xue-Ying,Luan, Yun,Qi, Tong-Gang,Sun, Chao,Wang, Jue,Hou, Hua-Ying,Jiang, Yu-Hua,Zhao, Jing-Jie,Cheng, Guang-Hui Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11

Adenocarcinoma of esophagus (AE) is a complex disease, affected by a variety of genetic and environmental factors. Much evidence has shown that the MutY glycosylase homologue (MUTYH) plays a key role in the pathogenesis of many cancers. However, there have been no reports on influence on AE in the Han Chinese population. The objective of this study was to investigate this issue. A gene-based association study was conducted using three single nucleotide polymorphisms(SNPs) reported in previous studies. The three SNPs (rs3219463, rs3219472, rs3219489) were genotyped in 207 unrelated AE patients and 249 healthy controls in a case-control study using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). The results revealed that the genotype distribution of rs3219472 differed between the case and control groups (OR=1.66,95%CI=1.11-2.48, P=0.012), indicating that an association may exist between MUTYH and AE. These findings support a signifcant role for MUTYH in AE pathogenesis in the Han Chinese population.

Optimal design of a plate-fin heat sink on the hot side of thermoelectric generator module for the recovery of waste heat

In this study, a plate fin heat sink is utilized for a TEG system to recover the waste heat which generated from a bronze ingot casting furnace with an impingement flow direction. Three-dimensional (3D) numerical model for the heat recovery system including the TEG module and the heat sink are developed and solved by using the commercial software ANSYS Icepak 19.2. Both of the effects of convection and radiation are considered. The ideal maximum power output of TEG module is evaluated by one dimensional model based on the temperature distribution of the TEG module which obtained from the 3D numerical simulation. The net power output of the TEG module is obtained by subtracting the pumping power from the ideal power output of the TEG module. The effect of operating parameters (velocity and temperature of waste heat flow) and fin parameters (fin height and numbers) on the heat transfer, TEG power output and efficiency are determined. The obtained conclusions in this research could provide valuable information for the design of an industrial TEG and waste heat recovery system.

Antitumorigenic and antiangiogenic efficacy of apatinib in liver cancer evaluated by multimodality molecular imaging

Jie Tian,Qian Liang,Lingxin Kong,Yang Du,Xu Zhu 생화학분자생물학회 2019 Experimental and molecular medicine Vol.51 No.-

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related mortality worldwide. Sorafenib is the standard first-line treatment for advanced HCC, but its efficacy is limited. Apatinib is a small-molecule tyrosine kinase inhibitor that has shown promising antitumor effects in gastric and non-small cell lung cancers in clinical trials, but there have been only a few studies reporting its anti-HCC effects in vitro and in HCC xenograft models. Hence, our present study systemically investigated and compared the antitumorigenic and antiangiogenic efficacy of apatinib and sorafenib in HCC in vitro and in vivo using multimodality molecular imaging, including bioluminescence imaging (BLI), bioluminescence tomography (BLT), fluorescence molecular imaging (FMI), and computed tomography angiography (CTA). Moreover, the safety and side effects of the two drugs were systemically evaluated. We found that apatinib showed a comparable therapeutic efficacy to sorafenib for the inhibition of HCC. The drug safety evaluation revealed that both of these drugs caused hypertension and mild liver and kidney damage. Sorafenib caused diarrhea, rash, and weight loss in mice, but these effects were not observed in mice treated with apatinib. In conclusion, apatinib has similar antitumorigenic and antiangiogenic efficacy as sorafenib in HCC with less toxicity. These findings may provide preclinical evidence supporting the potential application of apatinib for the treatment of HCC patients.

Damage monitoring of variable cross-section region in a column-drilled shaft assembly using smart aggregates

Jie Tan,Mahadi Masud,Xiaoming Qin,Cheng Yuan,Qingzhao Kong,Y.L.Mo 국제구조공학회 2021 Smart Structures and Systems, An International Jou Vol.28 No.5

Pier column, as the most critical load-bearing member of bridge, can bear multiple loads including axial forces,shear forces, bending moments, etc. The varied cross section at the column interface and bearing platform or drilled shaft leads to harmful stress concentration that can potentially compromise the structural integrity. In order to improve the ductility of bridge structure, a pier column is often designed with a variable cross-section region to dissipate energy through plastic deformation. For better understanding the health condition of pier column in its service life, it is of great significance to obtain the damage severity information in the variable cross-section region. This study utilizes an active sensing method enabled by distributed Lead Zirconate Titanate (PZT)-based Smart Aggregate (SA) sensors to monitor the damage initiation and development near the bottom of a pier column. Crack damage in variable cross-section region functions as a stress relief that attenuates propagating stress wave energy between SA pairs. Both the numerical and experimental results show that the reduction ratio of the stress wave energy is consistent with the crack development, thus validating the reliability of the investigated approach. SA-based technology can be used as a potential tool to provide early warning of damage in variable cross-section region of bridge structures.

Purpose: The European Organization for Research and Treatment of Cancer quality of life (QOL) questionnaires (QLQ-C30, QLQ-OG25, and QLQ-STO22) are widely used for the assessment of gastric cancer patients. This study aimed to use these questionnaires to evaluate QOL in postgastrectomy patients. Methods: We prospectively evaluated 106 patients with distal gastrectomy (DG), 57 with pylorus-preserving gastrectomy (PPG), and 117 with total gastrectomy (TG). Body weight and QOL questionnaires were evaluated preoperatively and postoperatively (at 3 weeks, and 3, 6, and 12 months). Results: TG patients had significantly more weight loss than DG/PPG patients. Compared with DG, patients after PPG had less dyspnea (P = 0.008) and trouble with coughing (P = 0.049), but more severe symptoms of insomnia (P = 0.037) and reflux (P = 0.030) at postoperative 12 months. Compared with DG/PPG, TG was associated with worse body image, dysphagia, eating, and taste in both OG25 and STO22. Moreover, OG25 revealed worse QOL in the TG group with respect to odynophagia, eating with others, choked when swallowing, trouble talking, and weight loss. The QOL of patients who received chemotherapy was worse than those in the chemo-free group in both physical functioning and symptoms such as nausea/vomiting, appetite loss, and trouble with taste; however, these side effects would soon disappear after finishing chemotherapy. Conclusion: PPG was similar to DG in terms of postoperative QOL and maintaining body weight, while TG was always inferior to both DG and PPG. Adjuvant chemotherapy can affect both body weight and QOL despite being reversible.
