| 2 | Diabetic retinopathy-ocular complications of diabetes mellitus显示文摘In industrialized nations diabetic retinopathy is the most frequent microvascular complication of diabetes mellitus and the most common cause of blindness in the workingage population.In the next 15 years,the number of patients suffering from diabetes mellitus is expected to increase significantly.By the year 2030,about 440 million people in the age-group 20-79 years are estimated to be suffering from diabetes mellitus worldwide(prevalence 7.7%),while in 2010 there were 285 million people with diabetes mellitus(prevalence 6.4%).This accounts for an increase in patients with diabetes in industrializednations by 20% and in developing countries by 69% until the year 2030.Due to the expected rise in diabetic patients,the need for ophthalmic care of patients(i.e.,exams and treatments) will also increase and represents a challenge for eye-care providers.Development of optimized screening programs,which respect available resources of the ophthalmic infrastructure,will become even more important.Main reasons for loss of vision in patients with diabetes mellitus are diabetic macular edema and proliferative diabetic retinopathy.Incidence or progression of these potentially blinding complications can be greatly reduced by adequate control of blood glucose and blood pressure levels.Additionally,regular ophthalmic exams are mandatory for detecting ocular complications and initiating treatments such as laser photocoagulation in case of clinical significant diabetic macular edema or early proliferative diabetic retinopathy.In this way,the risk of blindness can considerably be reduced.In advanced stages of diabetic retinopathy,pars-plana vitrectomy is performed to treat vitreous hemorrhage and tractional retinal detachment.In recent years,the advent of intravitreal medication has improved therapeutic options for patients with advanced diabetic macular edema. | Martin M Nentwich Michael W Ulbig | 2015 | World Journal of Diabetes2015，6，3： | 44 |

| 4 | 为表面的胃肠的瘤的移动的内视镜的 submucosal 解剖: 技术评论显示文摘 Endoscopic submucosal dissection (ESD) is now the most common endoscopic treatment in Japan for intramucosal gastrointestinal neoplasms (non-metastatic). ESD is an invasive endoscopic surgical procedure, requiring extensive knowledge, skill, and specialized equipment. ESD starts with evaluation of the lesion, as accurate assessment of the depth and margin of the lesion is essential. The devices and strategies used in ESD vary, depending on the nature of the lesion. Prior to the procedure, the operator must be knowledgeable about the treatment strategy(ies), the device(s) to use, the electrocautery machine settings, the substances to inject, and other aspects. In addition, the operator must be able to manage complications, should they arise, including immediate recognition of the complication(s) and its treatment. Finally, in case the ESD treatment is not successful, the operator should be prepared to apply alternative treatments. Thus, adequate knowledge and training are essential to successfully perform ESD. | Noriaki Matsui Kazuya Akahoshi Kazuhiko Nakamura Eikichi Ihara Hiroto Kita | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，4： | 34 |

| 6 | 提高肝癌介入治疗的疗效显示文摘由于我国是肝炎大国,肝癌发病率居高不下,每年约10万人死于肝癌,尽管作为肝癌首选治疗方法的手术切除,随着外科技术以及麻醉和护理手段的进步,肝癌的手术适应症不断放宽,手术范围几甚达到解剖学极限,但由于肝癌的特殊病理特点,患者早期常无症状,发现时多至中晚期,能手术切除者仅占10%~15%.而肝移植治疗地位虽已显现,但恐难成为主流.随着20世纪80年代影像医学的迅猛发展,为肝癌局部治疗打开了发展的空间.以血管介入治疗的经皮肝动脉栓塞化疗(transarterial chemoembolization,TACE),非血管介入的经皮无水乙醇注射治疗(percutaneous ethanol injection,PEI)为代表,射频冷冻、激光、微波、高频率聚焦超声等局部治疗方法,已成为多学科处理、多模式联合应用即综合治疗肝癌的重要环节.然而目前所倡导的综合治疗模式在临床实践中却常各自为政,缺乏系统化和规范化,各种治疗手段被盲目扩大化,甚至达到了滥用的程度,本文就提高肝癌介入治疗疗效作一述评. | 樊代明 韩国宏 孟祥杰 | 2006 | 中华消化杂志2006，26，5： | 29 |
| 7 | Prognostic factors for hepatocellular carcinoma recurrence显示文摘The recurrence of hepatocellular carcinoma,the sixth most common neoplasm and the third leading cause of cancer-related mortality worldwide,represents an important clinical problem,since it may occur after both surgical and medical treatment.The recurrence rate involves 2 phases:an early phase and a late phase.The early phase usually occurs within 2 years after resection;it is mainly related to local invasion and intrahepatic metastases and,therefore,to the intrinsic biology of the tumor.On the other hand,the late phase occurs more than 2 years after surgery and is mainly related to de novo tumor formation as a consequence of the carcinogenic cirrhotic environment.Since recent studies have reported that early and late recurrences may have different risk factors,it is clinically important to recognize these factors in the individual patient as soon as possible.The aim of this review was,therefore,to identify predicting factors for the recurrence of hepatocellularcarcinoma,by means of invasive and non-invasive methods,according to the different therapeutic strategies available.In particular the role of emerging techniques(e.g.,transient elastography)and biological features of hepatocellular carcinoma in predicting recurrence have been discussed.In particular,invasive methods were differentiated from non-invasive ones for research purposes,taking into consideration the emerging role of the genetic signature of hepatocellular carcinoma in order to better allocate treatment strategies and surveillance follow-up in patients with this type of tumor. | Antonio Colecchia Ramona Schiumerini Alessandro Cucchetti Matteo Cescon Martina Taddia Giovanni Marasco Davide Festi | 2014 | World Journal of Gastroenterology2014，20，20： | 28 |
| 8 | Possible link between long-term and short-term water injections and earthquakes in salt mine and shale gas site in Changning,south Sichuan Basin, China显示文摘Late at night on 17 June 2019,a magnitude 6.0 earthquake struck Shuanghe Town and its surrounding area in Changning County,Sichuan,China,becoming the largest earthquake recorded within the southern Sichuan Basin.A series of earthquakes with magnitudes up to 5.6 occurred during a short period after the mainshock,and we thus refer to these earthquakes as the Changning M6 earthquake sequence(or swarm).The mainshock was located very close to a salt mine,into which for^3 decades fresh water had been extensively injected through several wells at a depth of 2.7–3 km.It was also near(within^15 km)the epicenter of the 18 December 2018 M5.7 Xingwen earthquake,which is thought to have been induced by shale gas hydraulic fracturing(HF),prompting questions about the possible involvement of industrial activities in the M6 sequence.Following previous studies,this paper focuses on the relationship between injection and seismicity in the Shuanghe salt field and its adjacent Shangluo shale gas block.Except for a period of serious water loss after the start of cross-well injection in 2005–2006,the frequency of earthquakes shows a slightly increasing tendency.Overall,there is a good correlation between the event rate in the Shuanghe area and the loss of injected water.More than 400 M≥3 earthquakes,including 40 M≥4 and 5 M≥5 events,had been observed by the end of August 2019.Meanwhile,in the Shangluo area,seismicity has increased during drilling and HF operations(mostly in vertical wells)since about 2009,and dramatically since the end of 2014,coincident with the start of systematic HF in the area.The event rate shows a progressively increasing background with some fluctuations,paralleling the increase in HF operations.More than 700 M≥3 earthquakes,including 10 M≥4 and 3 M≥5 in spatially and temporally clustered seismic events,are correlated closely with active fracturing platforms.Well-resolved centroid moment tensor results for M≥4 earthquakes were shown to occur at very shallow depths around shale formations with active HF,in agreement with some of the clusters,which occurred within the coverage area of temporary or new permanent monitoring stations and thus have been precisely located.After the Xingwen M5.7 earthquake,seismic activity in the salt well area increased significantly.The Xingwen earthquake may have created a unidirectional rupture to the NNW,with an end point close to the NW-trending fault of the Shuanghe earthquake.Thus,a fault in the Changning anticline might have terminated the fault rupture of the Xingwen earthquake,possibly giving the Xingwen earthquake a role in promoting the Changning M6 event. | XingLin Lei ZhiWei Wang JinRong Su | 2019 | Earth and Planetary Physics2019，3，6： | 24 |
| 9 | Precision surgery for primary liver cancer显示文摘Liver resection remains the best curative option for primary liver cancer, such as hepatocellular carcinoma(HCC) and intrahepatic cholangiocarcinoma.In particular, in liver resection for HCC, anatomical resection of the tumor-bearing segments is highly recommended to eradicate the intrahepatic metastases spreading through portal venous branches.Anatomical liver resection,including anatomical segmentectomy and subsegmentectomy using the dye-injection method, is technically demanding and requires experience for completion of a precise procedure.The recent development of imaging studies and new computer technologies has allowed for the preoperative design of the operative procedure, intraoperative navigation, and postoperative quality evaluation of the anatomical liver resection.Although these new technologies are related to the progress of artificial intelligence, the actual operative procedure is still performed as human-hand work.A precise anatomical liver resection still requires meticulous exposure of the boundary of hepatic venous tributaries with deep knowledge of liver anatomy and utilization of intraoperative ultrasonography. | Takeshi Takamoto Masatoshi Makuuchi | 2019 | Cancer Biology & Medicine2019，16，3： | 23 |
| 10 | Non-polypoid colorectal neoplasms:Classification,therapy and follow-up显示文摘In the last years,an increasing interest has been raised on non-polypoid colorectal tumors(NPT) and in particular on large flat neoplastic lesions beyond 10 mm tending to grow laterally,called laterally spreading tumors(LST).LSTs and large sessile polyps have a greater frequency of high-grade dysplasia and local invasiveness as compared to pedunculated lesions of the same size and usually represent a technical challenge for the endoscopist in terms of either diagnosis and resection.According to the Paris classification,NPTs are distinguished in slightly elevated(0-Ⅱa,less than 2.5 mm),flat(0-Ⅱb) or slightly depressed(0-Ⅱc).NPTs are usually flat or slightly elevated and tend to spread laterally while in case of depressed lesions,cell proliferation growth progresses in depth in the colonic wall,thus leading to an increased risk of submucosal invasion(SMI) even for smaller neoplasms.NPTs may be frequently missed by inexperienced endoscopists,thus a careful training and precise assessment of all suspected mucosal areas should be performed.Chromoendoscopy or,if possible,narrow-band imaging technique should be considered for the estimation of SMI risk of NPTs,and the characterization of pit pattern and vascular pattern may be useful to predict the risk of SMI and,therefore,to guide the therapeutic decision.Lesions suitable to endoscopic resection are those confined to the mucosa(or superficial layer of submucosa in selected cases) whereas deeper invasion makes endoscopic therapy infeasible.Endoscopic mucosal resection(EMR,piecemeal for LSTs > 20 mm,en bloc for smaller neoplasms) remains the first-line therapy for NPTs,whereas endoscopic submucosal dissection in high-volume centers or surgery should be considered for large LSTs for which en bloc resection is mandatory and cannot be achieved by means of EMR.After piecemeal EMR,follow-up colonoscopy should be performed at 3 mo to assess resection completeness.In case of en bloc resection,surveillance colonoscopy should be scheduled at 3 years for adenomatous lesions ≥ 1 cm,or in presence of villous features or high-grade dysplasia patients(regardless of the size),while less intensive surveillance(colonoscopy at 5-10 years) is needed in case of single(or two) NPT < 1 cm presenting tubular features or low-grade dysplasia at histology. | Antonio Facciorusso Matteo Antonino Marianna Di Maso Michele Barone Nicola Muscatiello | 2015 | World Journal of Gastroenterology2015，21，17： | 20 |
| 11 | Management of small hepatocellular carcinoma in cirrhosis:Focus on portal hypertension显示文摘The incidence of hepatocellular carcinoma(HCC) is rising worldwide being currently the fifth most common cancer and third cause of cancer-related mortality.Early detection of HCC through surveillance programs have enabled the identification of small nodules with higher frequency,and nowadays account for 10%-15% of patients diagnosed in the West and almost 30% in Japan.Patients with small HCC can be candidates for potential curative treatments:liver transplantation,surgical resection and percutaneous ablation,depending on the presence of portal hypertension and co-morbidities.This review will analyze recent advancements in the clinical management of these individuals,focusing on issues related to the role of portal hypertension,the debate between resection and ablative therapies and the future impact of molecular technologies. | Virginia Hernandez-Gea Fanny Turon Annalisa Berzigotti Augusto Villanueva | 2013 | World Journal of Gastroenterology2013，19，8： | 20 |
| 12 | Clinical trials on corticosteroids for diabetic macular edema显示文摘Diabetic macular edema(DME)is a common cause of visual impairment in diabetic patients.It is caused by an increase in the permeability of the perifoveal capillaries and a disruption of the blood retinal-barrier.The pathogenesis of DME is multifactorial.Several therapeutic modalities have been proposed for the treatment of DME.Corticosteroid treatments have emerged as an alternative therapy for persistent DME or refractory to conventional laser photocoagulation and other modalities,due to anti-inflammatory,anti-vascular endothelial growth factor and anti-proliferative effects.Many studies have demonstrated the beneficial therapeutic effect of corticosteroids with improvement to both retinal thickness and visual acuity in short-term on the treatment of DME.Peribulbar and intravitreal injections have been used to deliver steroids for DME with frequent injections due to the chronic and recurrent nature of the disease.Steroid-related side effects include elevated intraocular pressure,cataract,and injection related complications such as endophthalmitis,vitreous hemorrhage,and retinal detachment particularly with intravitreal steroid injections.In order to reduce the risks,complications and frequent dosing of intravitreal steroids,intravitreal implants have been developed recently to provide sustained release of corticosteroids and reduce repeated intravitreal injections for the management of DME. | Hassan A Al Dhibi J Fernando Arevalo | 2013 | World Journal of Diabetes2013，4，6： | 17 |
| 13 | Effects of Honghua preserved amniotic membrane on scar healing in experimental glaucoma surgery显示文摘AIM:To investigate the efficacy and safety of Honghua preserved amniotic membrane(AM)for preventing scar formation of the filtering bleb in a rabbit model of glaucoma trabeculectomy surgery.METHODS:Totally 36 rabbits(36 eyes)were randomly divided into 3 groups:the experimental group(ocular trabeculectomy in combination with Honghua preserved AM transplantation),the control group(ocular trabeculectomy surgery in combination with AM implantation),and the blank group(single trabeculectomy).Clinical observations[including intraocular pressure(IOP),filtering blebs and complications],MassonTrichrome staining,real-time quantitative reverse transcription-polymerase chain reaction(real-time PCR),Western blot were performed on different time points(D1,D7,D14,D21 and D56)after the surgery.RESULTS:After operated for 14d,there were statistically significant differences in the filtering blebs compared to the situation before operation(P<0.05),whereas no statistically difference on that among three groups(P>0.05).After 21d,the IOP of experimental group was lowest(P<0.05).There was significant difference between control group and blank group(P<0.05).On postoperative D14,the mean number of fibroblasts in the experimental group was significantlylower(40.6±10.2)compared to those in the control group(54.4±10.8)and blank group(68.2±11.6)(P<0.05,respectively).The mean numbers of the macrophage in the experimental and control groups were respcitively significantly lower versus the blank group(P<0.05,P<0.05,respectively).Compared to that in blank group,the level of transforming growth factor-β(TGF-β1)expression in sclera and conjunctival areas was reduced in the experimental and control groups on protein and mRNA level(P<0.05),but not significant difference between these two groups(P>0.05).CONCLUSION:The trabeculectory surgery with Honghua preserved AM can control IOP,sustain the functional filtration bleb,inhibit the proliferation of fibroblasts and open the filtrating pathway on the rabbit glaucoma models. | Yi Shao Yao Yu Qiu-Ping Liu Jing-Ming Li Fei Dong Xin Huang Chong-Gang Pei Ping Tu Hen-Hui Li Gui-Ping Gao | 2014 | International Journal of Ophthalmology(English edition)2014，7，2： | 16 |
| 14 | Current status in the treatment options for esophageal achalasia显示文摘Recent advances in the treatment of achalasia include the use of high-resolution manometry to predict the outcome of patients and the introduction of peroral endoscopic myotomy(POEM).The first multicenter randomized,controlled,2-year follow-up study conducted by the European Achalasia Trial group indicated that laparoscopic Heller myotomy(LHM)was not superior to pneumatic dilations(PD).Publications on the long-term success of laparoscopic surgery continue to emerge.In addition,laparoscopic single-site surgery is applicable to advanced laparoscopic operations such as LHM and anterior fundoplication.The optimal treatment option is an ongoing matter of debate.In this review,we provide an update of the current progress in the treatment of esophageal achalasia.Unless new conclusive data prove otherwise,LHM is considered the most durable treatment for achalasia at the expense of increased reflux-associated complications.However,PD is the first choice for non-surgical treatment and is more costeffective.Repeated PD according to an'on-demand'strategy based on symptom recurrence can achieve long-term remission.Decision making should be based on clinical evidence that identifies a subcategory of patients who would benefit from specific treatment options.POEM has shown promise but its long-term efficacy and safety need to be assessed further. | Seng-Kee Chuah Chien-Hua Chiu Wei-Chen Tai Jyong-Hong Lee Hung-I Lu Chi-Sin Changchien Ping-Huei Tseng Keng-Liang Wu | 2013 | World Journal of Gastroenterology2013，19，33： | 15 |
| 15 | Protective effect of Danhong injection in patients with acute myocardial infarction at a high risk of no-reflow during primary percutaneous coronary intervention显示文摘Objective To observe the effect of Danhong injection(DI)in patients with acute ST-segment elevation myocardial infarction(STEMI)at a high risk of no-reflow(NR)during primary percutaneous coronary intervention(PCI).Methods Patients were placed in a DI group and control group.The DI group was given DI and the control group was given physiologic saline.The administration lasted 4 to 6 days in both groups after PCI.Cardiac magnetic resonance(CMR)was carried out during the perioperative period(7±2 days).The primary endpoint of the study was myocardial infarct size(IS)imaged on delayed-enhancement CMR.The secondary endpoint was major adverse cardiac events observed 6 months after PCI.Results In total,160 high-risk NR patients were enrolled,and 110 patients completed the CMR examination.According to postoperative CMR,the Myocardial Salvage Index and left ventricular ejection fraction were higher in the DI group(0.57±0.13 vs.0.48±0.17,P<0.01;49.3%±6.9%vs.46.2%±7.7%,P=0.03,respectively),whereas the IS was lower(19.7%±5.6%vs.22.2%±6.5%,P=0.04),compared with that in the control group.These differences were observed to be significant.After 6 months,the prevalence of major adverse cardiac events in the DI group decreased compared with that in the control group,but the differences were not observed to be significant(P>0.05).Conclusion The application of DI can reduce the myocardial infarct size in STEMI patients at a high risk of NR during primary PCI. | Qi YOU Jing WANG Wei DONG Feng TIAN Hong-Xu LIU Jing JING Yun-Dai CHEN | 2019 | Journal of Geriatric Cardiology2019，16，5： | 15 |
| 16 | Portal vein embolization by fine needle ethanol injection :experimental and clinicalstudies显示文摘AIM To improve the technique of intraportal embolization (PVE) therapy, a new embolic method, was devised and the safety, effectiveness and feasibility were evaluated. METHODS PVE with intraportal ethanol injection via a fine needle was performed in 28 normal dogs, 22 SD rats, and 24 cirrhotic SD rats. After PVE, portography, histological and functional alteration of the liver were evaluated in dogs and rats, and the changes in portal hemodynamics as well as hepatic anatomy were observed in rats. In the clinical study, PVE by ethanol injection was performed in 61 patients with hepatocellular carcinoma under the guidance of portoechography with intraportal injection of CO 2. The effect of PVE was evaluated by ultrasonography and laparotomy. RESULTS The effectiveness and toxicity were dependent on the dose of ethanol. In the dogs, 0 25*!mg/*!kg of ethanol caused incomplete embolization with least liver damage, while 1 0*!mg/*!kg induced complete embolization with a high mortality of 57 1% (4/*!7) due to respiratory arrest. The dose of 0 5*!mg/*!kg resulted in complete embolization with slight toxicity to the liver. In the rats, the survival rate was 100% in normal group but 40 9% in cirrhotic models after ethanol injection by dose of 0 05*!mg/*!100*!g . PVE for cirrhotic rats with 0 03*!mg/*!100*!g of ethanol induced satisfactory embolization with significant hypertrophy in nonembolized lobes, and only slight damage to the hepatic parenchyma, and transient alteration in liver function, portal pressure and portal flow. In the clinical study, 12 cases with reverse portal flow were excluded judged by portoechography. Satisfactory embolization was gained in 90 2% (55/*!61) of the remaining patients determined by ultrasonography and surgery. All cases ran an uneventful postembolization course with no aberrant embolization. CONCLUSION PVE with intraportal ethanol injection of appropriate dosage via a fine needle is safe and effective and has several advantages comparing with transcatheter method. Portoechography is a mandatory approach for the prevention of aberrant embolization. | Lu MD Chen JW Xie XY Liang LJ Huang JF | 1999 | World Journal of Gastroenterology1999，5，6： | 15 |
| 17 | Solvent de binding of water soluble binder in powder injection moulding显示文摘The solvent debinding of water soluble binder in powder injection moulding (MIM) was investigated systematically, including the effects of solvent types, temperature and the thickness of green parts on the solvent debinding rate. After studying the debinding of a green part with a thickness of 4.26 mm, it was found that, the debinding rate of polyethylene glycol(PEG) in water and alcohol was high initially, and then decreased; however, it would increase with temperature increasing. At room temperature, the dissolution rate of PEG in water was higher than that in alcohol, but the latter would be much faster with temperature increasing because the debinding activation energy in alcohol was 51.44 kJ·mol -1 ·K -1 , much higher than 24.23 kJ·mol -1 ·K -1 in water. With a green part thickness larger than 4.26 mm, the debinding was controlled by diffusion; but with that smaller than 2.36 mm, the debinding was controlled by both dissolution and diffusion. | Li Songlin(李松林) Huang Baiyun(黄伯云) Qu Xuanhui(曲选辉) Li Yimin(李益民) | 1999 | 中国有色金属学会会刊:英文版1999，9，3： | 14 |
| 18 | Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD. | Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao | 2018 | Bone Research2018，6，3： | 13 |
| 19 | Solutions for submucosal injection: What to choose and how to do it显示文摘During the past decades, endoscopic resection techniques have gradually improved and gained more importance for the management of premalignant lesions and early cancers. These endoscopic resection techniques can be divided in 3 major groups: snare polipectomy, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD). The use of submucosal injection is essential for the majority of EMR techniques and is an integral part of ESD,whereas during polipectomy it is not crucial in most cases except to prevent bleeding in large polyps and/or those with large stalks as an alternative to mechanical methods. Injection provides a lifting up effect of the lesion separating it from the muscular layer, thereby reducing thermal injury and the risk of perforation and bleeding while also facilitating en-bloc resection by improving technical feasibility. With this work, we aim to review the most common endoscopic resection techniques and the importance of submucosal injection in each one of them. For that, we present some of the most commonly used submucosal injection solutions, taking into account their advantages and disadvantages. We also discuss, based on current recommendations and our own experience, how and when to preform submucosal injection, depending on lesions features and endoscopic resection technique that′s being used, to assure complete resection and to prevent associated adverse events. Finally, we also present and discuss some new proposed submucosal injection solutions,endoscopic resection techniques and devices that may have a major impact on the future of therapeutic endoscopy. | Rui Castro Diogo Libanio Inês Pita Mário Dinis-Ribeiro | 2019 | World Journal of Gastroenterology2019，25，7： | 13 |
| 20 | In vivo theranostics with near-infraredemitting carbon dots—highly efficient photothermal therapy based on passive targeting after intravenous administration显示文摘Carbon dots that exhibit near-infrared fluorescence(NIR CDs)are considered emerging nanomaterials for advanced biomedical applications with low toxicity and superior photostability and targeting compared to currently used photoluminescence agents.Despite progress in the synthesis of NIR CDs,there remains a key obstacle to using them as an in vivo theranostic agent.This work demonstrates that the newly developed sulfur and nitrogen codoped NIR CDs are highly efficient in photothermal therapy(PTT)in mouse models(conversion efficiency of 59%)and can be readily visualized by photoluminescence and photoacoustic imaging.The real theranostic potential of NIR CDs is enhanced by their unique biodistribution and targeting.Contrary to all other nanomaterials that have been tested in biomedicine,they are excreted through the body’s renal filtration system.Moreover,after intravenous injection,NIR CDs are accumulated in tumor tissue via passive targeting,without any active species such as antibodies.Due to their accumulation in tumor tissue without the need for intratumor injection,high photothermal conversion,excellent optical and photoacoustic imaging performance,and renal excretion,the developed CDs are suitable for transfer to clinical biomedical practice. | Xin Bao Ye Yuan Jingqin Chen Bohan Zhang Di Li Ding Zhou Pengtao Jing Guiying Xu Yingli Wang Kateřina Holá Dezhen Shen Changfeng Wu Liang Song Chengbo Liu Radek Zbořil Songnan Qu | 2018 | Light(Science & Applications)2018，7，1： | 13 |
