| 1 | NKX6.3 protects against gastric mucosal atrophy by downregulatingβ-amyloid production显示文摘BACKGROUND Atrophic gastritis is characterized by loss of appropriate glands and reduction in gastric secretory function due to chronic inflammatory processes in gastric mucosa. Moreover, atrophic gastritis is considered as a precancerous condition of gastric cancer. However, little is known about the molecular mechanism underlying gastric mucosal atrophy and its contribution to gastric carcinogenesis.Thus, we hypothesized that transcription factor NKX6.3 might be involved in maintaining gastric epithelial homeostasis by regulating amyloid β(Aβ)production.AIM To determine whether NKX6.3 might protect against gastric mucosal atrophy by regulating Aβ production.METHODS We identified NKX6.3 depletion induced cell death by cell count and Western blot assay. Production and mechanism of Aβ oligomer were analyzed by enzymelinked immunosorbent assay, Western blot, immunoprecipitation, real-timequantitative polymerase chain reaction and immunofluorescence analysis. We further validated the correlation between expression of NKX6.3, Helicobacter pylori CagA, Aβ oligomer, apolipoprotein E(ApoE), and β-secretase 1(Bace1) in 55 gastric mucosae.RESULTS NKX6.3 depletion increased both adherent and floating cell populations in HFE-145 cells. Expression levels of cleaved caspase-3,-9, and poly ADP ribose polymerase were elevated in floating HFE-145^(shNKX6.3) cells. NKX6.3 depletion produced Aβ peptide oligomers, and increased expression of ApoE, amyloid precursor protein, Aβ, Bace1, low-density lipoprotein receptor, nicastrin, high mobility group box1, and receptor for advanced glycosylation end product proteins. In immunoprecipitation assay, γ-secretase complex was stably formed only in HFE-145^(shNKX6.3) cells. In gastric mucosae with atrophy, expression of Aβpeptide oligomer, ApoE, and Bace1 was detected and inversely correlated with NKX6.3 expression. Treatment with recombinant Aβ 1-42 produced Aβoligomeric forms and decreased cell viability in HFE-145^(shNKX6.3) cells. Additionally,NKX6.3 depletion increased expression of inflammatory cytokines and cyclooxygenase-2.CONCLUSION NKX6.3 inhibits gastric mucosal atrophy by regulating Aβ accumulation and inflammatory reaction in gastric epithelial cells. | Jung Hwan Yoon Yeon Soo Lee Olga Kim Hassan Ashktorab Duane T Smoot Suk Woo Nam Won Sang Park | 2019 | World Journal of Gastroenterology2019,25,3: | 6 |

| 3 | Histone deacetylase inhibitor pre-treatment enhances the efficacy of DNA-interacting chemotherapeutic drugs in gastric cancer显示文摘BACKGROUND The prognosis of gastric cancer continues to remain poor,and epigenetic drugs like histone deacetylase inhibitors(HDACi)have been envisaged as potential therapeutic agents.Nevertheless,clinical trials are facing issues with toxicity and efficacy against solid tumors,which may be partly due to the lack of patient stratification for effective treatments.To study the need of patient stratification before HDACi treatment,and the efficacy of pre-treatment of HDACi as a chemotherapeutic drug sensitizer.METHODS The expression activity of class 1 HDACs and histone acetylation was examined in human gastric cancer cells and tissues.The potential combinatorial regime of HDACi and chemotherapy drugs was defined on the basis of observed drug binding assays,chromatin remodeling and cell death.RESULTS In the present study,the data suggest that the differential increase in HDAC activity and the expression of class 1 HDACs are associated with hypoacetylation of histone proteins in tumors compared to normal adjacent mucosa tissue samples of gastric cancer.The data highlights for the first time that pretreatment of HDACi results in an increased amount of DNA-bound drugs associated with enhanced histone acetylation,chromatin relaxation and cell cycle arrest.Fraction-affected plots and combination index-based analysis show that pre-HDACi chemo drug combinatorial regimes,including valproic acid with cisplatin or oxaliplatin and trichostatin A with epirubicin,exhibit synergism with maximum cytotoxic potential due to higher cell death at low combined doses in gastric cancer cell lines.CONCLUSION Expression or activity of class 1 HDACs among gastric cancer patients present an effective approach for patient stratification.Furthermore,HDACi therapy in pretreatment regimes is more effective with chemotherapy drugs,and may aid in predicting individual patient prognosis. | Ramchandra Vigay Amnekar Shafqat Ali Khan Mudasir Rashid Bharat Khade Rahul Thorat Poonam Gera Shailesh V Shrikhande Duane T Smoot Hassan Ashktorab Sanjay Gupta | 2020 | World Journal of Gastroenterology2020,26,6: | 3 |

| 6 | 儿童心脏移植后的体外膜肺氧合支持:单中心队列研究显示文摘目的体外膜肺氧合(extracorporeal membrane oxygenation,ECMO)用于心脏切开术后低心排患儿,但较少用于心脏移植后。本文总结了心脏移植后接受ECMO支持患儿的预后特点。设计单中心回顾性研究。场所大型儿童心脏转诊中心。对象1995至2016年所有接受心脏移植且插管行ECMO支持的患儿。干预措施主要预后指标为ECMO后12个月的病死率。根据早期移植失败(心脏移植后ECMO≤7 d)和晚期移植失败,分析患儿的特点及与预后的相关性。测量方法和主要结果研究期间共进行了246例心脏移植手术,其中44例患儿进行了50次ECMO。心脏移植至ECMO的中位时间为1 d(0 d~11.7年),其中28例患儿早期移植失败[1(0~2)d],20例晚期移植失败患儿共行22次ECMO[中位时间0.8年(8 d~11.7年)],其中4例患儿之前因早期移植失败亦接受过ECMO支持。26例(59%)患儿存活至出院,24例(55%)患儿ECMO后12个月仍存活,晚期移植失败患儿的存活率较低(40%比67%,P=0.02)。12个月病死率的独立危险因素包括先天性心脏病、较高的肺血管阻力指数别体表面积值(>2.2 Woods U/m^(2))和较高的肌酐值。高群体反应性抗体水平仅与晚期移植失败组12个月病死率有关。结论ECMO可有效地用于抢救心脏移植后移植功能障碍的患儿,但其早期病死率较高。与12个月内病死率相关的因素包括先天性心脏病、肾功能不全、肺血管阻力指数别体表面积值升高;在心脏移植后晚期ECMO支持患儿还包括高HLA致敏性。 | Nair AG Sleeper LA Smoot LB 方伯梁(译) 钱素云(校) | 2021 | 中国小儿急救医学2021,28,2: | 2 |
