BACKGROUND Recurrence is the major challenge facing endoscopic submucosal dissection(ESD)-based treatment therapies for early gastric cancer(EGC).Urgent development of simple and easy surveillance approaches will enhance clinical treatment of the disease.AIM To explore the role of computed tomography(CT)recurrence in evaluating EGC after ESD treatment.METHODS We retrospectively recruited patients from our endoscopy department,between January 2002 and December 2015,and analyzed their basic characteristics,including symptoms,CT results,and results of endoscopy with biopsy,among others.RESULTS Among a total of 2150 patients EGC patients surveyed,1362 met our inclusion and exclusion criteria and were therefore enrolled in our study.The cohort’s sensitivity of CT for recurrent GC and specificity were 44.22%and 43.86%,respectively,with negative and positive predictive values of 40.15%(275/685)and 48.01%(325/677),respectively.The area under the curve of arterial and venous CT values for recurrent EGC were 0.545,and 0.604,respectively.Receiver operating characteristic curve revealed no statistically significant differences between arterial and venous CT values for recurrent EGC.CONCLUSION Enhanced CT has superior diagnostic efficacy,but less accuracy,compared to gold standard techniques in patients with recurrent EGC.

目的比较产NDM-1和产KPC-2耐碳青霉烯类肺炎克雷伯菌(CRKP)的临床及分子流行病学特征。方法回顾性分析2017—2020年某儿童医院非重复儿童住院患者临床分离的CRKP,查阅菌株来源患者的病历资料获得患者的基本临床特征。对CRKP进行药敏试验及多位点序列分型(MLST)分析,比较产NDM-1和产KPC-2的CRKP临床及分子流行病学特征。结果2017—2020年共收集164株CRKP菌株,其中96株携带bla NDM-1,68株携带bla KPC-2,产NDM-1的CRKP主要分布在新生儿科室,产KPC-2的CRKP以非新生儿科室居多,两组在标本来源、患者年龄、科室分布和预后情况方面比较,差异均有统计学意义(均P<0.05);产NDM-1的CRKP菌株以ST 17型和ST 278型为主,分别为40.63%、18.75%;而产KPC-2的CRKP菌株以ST 11为主,达73.53%。产KPC-2的CRKP分离株对头孢吡肟、氨曲南、亚胺培南、阿米卡星、庆大霉素、呋喃妥因和磷霉素的耐药率均高于产NDM-1的CRKP分离株,差异均有统计学意义(均P<0.05)。结论产NDM-1和产KPC-2的CRKP菌株在临床及分子流行病学方面均存在差异,产KPC-2的CRKP菌株表现出更严重的耐药性,感染KPC-2 CRKP的患者预后较差,应引起临床和感控的重视。

基于含氟聚合物的强氧化及含氟量高的特性,以聚偏二氟乙烯(PVDF)为代表,通过电泳技术,采用石胆酸(LCA)作为表面活性剂,制备了PVDF/Al/CuO有机/无机杂化含能薄膜,并对其组分、结构、形貌及含能特性进行了系统的表征。结果表明:PVDF电泳沉积过程中石胆酸的最佳添加剂量为3mL(1wt%);当PVDF添加量为2wt%时,PVDF/Al/CuO复合薄膜的燃烧性能最好,热释放能量达3924J/g,远远高于Al/CuO的热释放能量。产生上述实验结果的主要原因是PVDF本身具有氧化特性,能够与铝发生化学反应,释放热量;此外,PVDF热分解产生的氟能够腐蚀铝表面的钝化膜,进而释放活性铝,极大提升了Al/CuO体系的能量释放效果。

3D bioprinting has the capability to create 3D cellular constructs with the desired shape using a layer-by-layer approach.Inkjet 3D bioprinting,as a key component of 3D bioprinting,relies on the deposition of cell-laden droplets to create native-like tissues/organs which are envisioned to be transplantable into human body for replacing damaged ones.Benefiting from its superiorities such as high printing resolution and deposition accuracy,inkjet 3D bioprinting has been widely applied to various areas,including,but not limited to,tissue engineering and drug screening in pharmaceutics.Even though inkjet 3D bioprinting has proved its feasibility and versatility in various fields,the current applications of inkjet 3D bioprinting are still limited by the printing technique and material selection.This review,which specifically focuses on inkjet 3D bioprinting,firstly summarizes the techniques,materials,and applications of inkjet 3D bioprinting in tissue engineering and drug screening,subsequently discusses the major challenges that inkjet 3D bioprinting is facing,and lastly summarizes potential solutions to those challenges.

Thermite films are typical energetic materials(EMs)and have great value in initiating explosive devices.However,research in thermite film preparation is far behind that of research in thermite powders.Electrophoretic deposition(EPD)is an emerging,rapid coating method for film fabrication,including of energetic composite films.In this work,a polytetrafluoroethylene(PTFE)/Al/CuO organic-inorganic hybrid energetic film was successfully obtained using the above method for the first time.The addition of lithocholic acid as a surfactant into the electroplating suspension enabled PTFE to be charged.The combustion and energy release were analyzed by means of a high-speed camera and differential scanning calorimetery(DSC).It was found that the combustion process and energy release of PTFE/Al/CuO were much better than that of Al/CuO.The main reason for the excellent combustion performance of the hybrid PTFE/Al/CuO system was that the oxidability of PTFE accelerated the redox reaction between Al and CuO.The prepared PTFE/Al/CuO film was also employed as ignition material to fire a B-KNO_3 explosive successfully,indicating considerable potential for use as an ignition material in micro-ignitors.This study sheds light on the preparation of fluoropolymer-containing organic-inorganic hybrid energetic films by one-step electrophoretic deposition.

Abstract L2 VOcabulary Knowledge Acquisition: A Cross-sectional Study on WOrd Meaning ＆ Collocation Base on a vocabulary knowledge framework put fomrd by Richards and Nation, the present study investigates the develoPment of the dePth of vocabulary Anowledge. This study investigates how Chinese EFL learners at three different EFL Proficiency levels acquire 2 tyPes of vocabulary knoWedge, name1y meanng and collocation, both recePtively and productively 75 Chinese EFL university learners were testCd on their recePtive and productive mastery of the 2 tyPes of vocabulary knowledge fOr each of the 8 high frequency words we chose as the test words. The following findings were obtained in the present study f l) generally sPeaking, the subjects’ total vocabulary kno\viedge highly correlates with their EFL proficiency levels both receptively and productively, suggesting a concurrent development in the dePth of vocabulary knowledge. 2) the subjects’ vocabulary Anowledge, on the Whole, correlates with their vocabulary size. Howevef, this does not suggeSt that a langr vocabulary size necessarily ends up with a deePer vocabulary knowledge. 3) there is a wide gaP between the subjects’ recePtive knowledge and productive knowIedge of the two tyPes of vocabulary knowledge, which may be due to both cognitive aspects and outside input in EFL leaming. 4) meaning Anowledge increases quickiy at low proficiency level While collocation knowledge develop faster at higher proficiency levels.
