1剖腹产疤痕子宫内膜异位症显示文摘子宫内膜异位症是一常见而又疑难的疾病,尽管一个世纪以前已有描述,但至今仍是临床医生和研究者继续争论的问题。剖腹产腹壁疤痕子宫内膜异位症不多见,文献报告更少。本文报告近5年内证实的5例,并收集1956年以来的文献19篇,共90例疤痕子宫内膜异位症,对其诊断和治疗进行讨论。所收集的疤痕子宫内膜异位症的临床特征类似。年龄范围在21~40岁,疤痕中均有周期性触痛包块。Wolf GC Singh KB 陈韵仙 1990国外医学(妇产科学分册)1990,17,2:82
2运动处方研究进展显示文摘目的本文试图通过对近半个世纪以来运动处方的产生及其发展过程,以及各阶段的特点进行分析和评价,为运动处方、运动康复疗法和机能评定在我国的普及应用提供理论和实践依据。方法采用计算机网络文献和资料收集法,对Medlin via Ovid、PubMed、Sport Discus、CINAHL、CAM、EMbase和EBM Cochrane Databaseof SR 7个数据库进行检索,检索词为exercise prescription、physical tness、exercise therapy、tness assessment、exercise test、randomized,检索时间均从建库至2008年6月。然后对其中的随机和非随机对照研究,以及资料较全者纳入分析讨论。结果共检索到318篇文献,但其中涉及运动处方和机能评定的随机对照试验(RCT)仅有7篇,系统评价和Meta分析各1篇。我们对其中资料较全又有代表性的93篇文献进行了系统分析讨论。结果显示:最早的运动处方和机能评定研究可以追溯到1950年,其发展与运动康复疗法的发展密不可分。二十世纪70年代是运动处方发展的初始期,首先是在身体活动与心血管健康方面提出了运动处方的概念,而后逐步提出了针对个体的运动处方,进而开始把运动处方与体能测试联系在一起讨论。二十世纪80年代运动处方开始进入了全面发展的阶段,开始用体能测试指导运动处方,并使运动处方和机能评定进入实验阶段。二十世纪90年代运动处方开始与多种运动康复疗法相结合,针对多种疾病进行干预和治疗,并与多种体能训练方法相结合指导训练和康复,成为一种主要的非药物治疗手段。进入本世纪以后,运动处方和机能评定的研究得到了全面提高,开始出现非随机对照试验和RCT,一些先进的测试手段和分析方法开始应用于机能评定和运动处方的实施。结论运动处方的发展与运动康复疗法和运动机能评定的发展是密不可分的,机能评定和体能测试是执行和实施运动处方的基础。当今,运动处方已从单一的体育锻炼方法提高到了针对多种疾病的非药物治疗手段。运动处方和机能评定的科学化已从观察性研究、群体研究,开始进入了非随机对照试验和RCT。相对其它生物学科而言,运动处方的RCT研究相对滞后,如何使运动处方获得最大的益处和最低的风险仍是值得研究的问题。步斌 侯乐荣 周学兰 韩海军 李良刚 张超慧 Maria Singh 2010中国循证医学杂志2010,10,12:78
3评估大气细颗粒物暴露引起的全球疾病负担的一个综合风险函数显示文摘[背景]评估由于环境空气中细颗粒物(PM2.5)长期暴露引起的疾病负担,需要了解相对风险度(RR)函数的图形和幅度。然而,在世界上很多观察到高PM2.5环境浓度的地方,都缺乏足够的直接证据确定死亡RR函数的图形。[目的]建立可用于全球PM2.5暴露范围内成人死因的RR函数:缺血性心脏病(IHD)、脑血管疾病(脑卒中)、慢性阻塞性肺病(COPD)和肺癌(LC)。建立急性下呼吸道感染(ALRI)发病的RR函数,用于估算〈5岁的儿童中死亡率和健康生活损失年数。[方法]通过整合现有的来自于环境空气污染(AAP)、二手烟草烟雾、家用固体烹饪用燃料和主动吸烟(AS)等研究的RR信息,拟合综合暴露-反应(IER)模型。采用颗粒物质的吸入剂量,通过转化AS暴露来估计全年PM2.5的暴露当量。在估算全球环境PM2.5浓度的基础上,得出各国的人群归因分数(PAFs)。[结果]与以往负担评估中使用的其他7种模型相比,IER模型是一种优越的RR预测方法。在不同国家中,归因于AAP暴露的PAF百分数各不相同,分别为:IHD,2~41;脑卒中,1~43;COPD,〈1~21;LC,〈1~25;ALRI,〈1~38。[结论]我们建立了一种以细颗粒物为基础的RR模型,它通过整合来自不同类型的燃烧所产生颗粒物排放的RR信息,涵盖全球范围的暴露。当获得新的RR信息时,可以对这个模型进行更新。Richard T.Burnett C.Arden Pope III Majid Ezzati Casey Olives Stephen S.Lim Sumi Mehta Hwashin H.Shin Gitanjali Singh Bryan Hubbell Michael Brauer H.Ross Anderson Kirk R.Smith John R.Balmes Nigel G.Bruce Haidong Kan Francine Laden Annette Prüss-Ustün Michelle C.Turner Susan M.Gapstur W.Ryan Diver Aaron Cohen 何蓉 张伊人 金泰廙 2014环境与职业医学2014,31,11:80
4An insight into the diagnosis and pathogenesis of hepatitis C virus infection显示文摘This review focuses on research findings in the area of diagnosis and pathogenesis of hepatitis C virus(HCV)infection over the last few decades.The information based on published literature provides an update on these two aspects of HCV.HCV infection,previously called blood transmitted non-A,non-B infection,is prevalent globally and poses a serious public health problem worldwide.The diagnosis of HCV infection has evolved from serodetection of non-specific and low avidity anti-HCV antibodies to detection of viral nucleic acid in serum using the polymerase chain reaction(PCR)technique.Current PCR assays detect viral nucleic acid with high accuracy and the exact copy number of viral particles.Moreover,multiplex assays using real-time PCR are available for identification of HCV-genotypes and their isotypes.In contrast to previous methods,the newly developed assays are not only fast and eco-nomic,but also resolve the problem of the window period as well as differentiate present from past infection.HCV is a non-cytopathic virus,thus,its pathogenesis is regulated by host immunity and metabolic changes including oxidative stress,insulin resistance and hepatic steatosis.Both innate and adaptive immunity play an important role in HCV pathogenesis.Cytotoxic lymphocytes demonstrate crucial activity during viral eradication or viral persistence and are influenced by viral proteins,HCV-quasispecies and several metabolic factors regulating liver metabolism.HCV pathogenesis is a very complex phenomenon and requires further study to determine the other factors involved.Mohammad Irshad Dhananjay Singh Mankotia Khushboo Irshad 2013World Journal of Gastroenterology2013,19,44:52
5Zn、Cd单一及复合污染对黑麦草根分泌物及根际Zn、Cd形态的影响显示文摘采用根袋土培试验,研究了锌、镉单一及复合污染对重金属富集植物黑麦草生长、锌镉积累、根分泌物及根际Zn、Cd形态的影响.结果表明,锌镉共存下(8 mmol/kg Zn+2 mmol/kg Cd),黑麦草对锌、镉的吸收为协同效应;仅镉污染时(2 mmol/kg Cd),镉对植株吸收锌为抑制效应.黑麦草吸收的锌、镉主要集中在地上部,以锌、镉复合污染时植株地上部对锌、镉的富集量最大,分别达到3 108.72、73.97 mg/kg,具有作为土壤重金属锌、镉污染植物修复材料的潜力.根际的松结合态锌、镉(交换态、碳酸盐结合态和铁锰结合态)含量大于其非根际的松结合态锌、镉含量.Cd污染和Zn、Cd复合污染的根际和非根际土壤镉形态均以交换态>碳酸盐结合态>铁锰结合态>残渣态>有机结合态.Zn污染及Zn、Cd复合污染根际和非根际土壤各锌形态以铁锰结合态>碳酸盐结合态>残渣态>有机结合态>交换态,而Cd污染的根际和非根际的锌形态则以残渣态>铁锰结合态>有机结合态>碳酸盐结合态>交换态.Zn、Cd污染促进了黑麦草根系氨基酸的分泌,降低了根际土壤的pH值,以Zn、Cd复合污染根际土壤氨基酸总量最大,分别为对照、Zn和Cd污染的1.95、1.54和1.40倍,根际土壤的pH值最低(5.18).根际氨基酸含量在重金属胁迫下明显增加,可能与黑麦草适应重金属胁迫有关.根际pH值高于非根际是根际Zn、Cd有效性大于非根际的重要原因.徐卫红 王宏信 刘怀 熊治庭 Balwant Singh 2007环境科学2007,28,9:56

7Treatment options for alcoholic and non-alcoholic fatty liver disease: A review显示文摘Alcoholic liver disease(ALD)and non-alcoholic fatty liver disease(NAFLD)are serious health problems worldwide.These two diseases have similar pathological spectra,ranging from simple steatosis to hepatitis to cirrhosis and hepatocellular carcinoma.Although most people with excessive alcohol or calorie intake display abnormal fat accumulation in the liver(simple steatosis),a small percentage develops progressive liver disease.Despite extensive research on understanding the pathophysiology of both these diseases there are still no targeted therapies available.The treatment for ALD remains as it was 50 years ago:abstinence,nutritional support and corticosteroids(or pentoxifylline as an alternative if steroids are contraindicated).As for NAFLD,the treatment modality is mainly directed toward weight loss and co-morbidity management.Therefore,new pathophysiology directed therapies are urgently needed.However,the involvement of several inter-related pathways in the pathogenesis of these diseases suggests that a single therapeutic agent is unlikely to be an effective treatment strategy.Hence,a combination therapy towards multiple targets would eventually be required.In this review,we delineate the treatment options in ALD and NAFLD,including various new targeted therapies that are currently under investigation.We hope that soon we will be having an effective multi-therapeutic regimen for each disease.Sukhpreet Singh Natalia A Osna Kusum K Kharbanda 2017World Journal of Gastroenterology2017,23,36:45
8A scientometric review of biochar research in the past 20 years(1998-2018)显示文摘Biochar is the carbon-rich product obtained from the thermochemical conversion of biomass under oxygen-limited conditions.Biochar has attained extensive attention due to its agronomical and environmental benefits in agro-ecosystems.This work adopts the scientometric analysis method to assess the development trends of biochar research based on the literature data retrieved from the Web of Science over the period of 1998-2018.By analysing the basic characteristics of 6934 publications,we found that the number of publications grew rapidly since 2010.Based on a keyword analysis,it is concluded that scholars have had a fundamental recognition of biochar and preliminarily found that biochar application had agronomic and environmental benefits during the period of 1998-2010.The clustering results of keywords in documents published during 2011-2015 showed that the main research hotspots were“biochar production”,“biochar and global climate change”,“soil quality and plant growth”,“organic pollutants removal”,and“heavy metals immobilization”.While in 2016-2018,beside these five main research hotspots,“biochar and composting”topic had also received greater attention,indicating that biochar utilization in organic solid waste composting is the current research hotspot.Moreover,updated reactors(e.g.,microwave reactor,fixed-bed reactor,screw-feeding reactor,bubbling fluidized bed reactor,etc.)or technologies(e.g.,solar pyrolysis,Thermo-Catalytic Reforming process,liquefaction technology,etc.)applied for efficient energy production and modified biochar for environmental remediation have been extensively studied recently.The findings may help the new researchers to seize the research frontier in the biochar field.Ping Wu Syed Tahir Ata-Ul-Karim Bhupinder Pal Singh Hailong Wang Tongliang Wu Cun Liu Guodong Fang Dongmei Zhou Yujun Wang Wenfu Chen 2019Biochar2019,1,1:36
9Targeting the PI3K/Akt signaling pathway in gastric carcinoma: A reality for personalized medicine?显示文摘Frequent activation of phosphatidylinositol-3 kinases(PI3K)/Akt/m TOR signaling pathway in gastric cancer(GC) is gaining immense popularity with identification of mutations and/or amplifications of PIK3 CA gene or loss of function of PTEN,a tumor suppressor protein,to name a few; both playing a crucial role in regulating this pathway. These aberrations result in dysregulation of this pathway eventually leading to gastric oncogenesis,hence,there is a need for targeted therapy for more effective anticancer treatment. Several inhibitors are currently in either preclinical or clinical stages for treatment of solid tumors like GC. With so many inhibitors under development,further studies on predictive biomarkers are needed to measure the specificity of any therapeutic intervention. Herein,we review the common dysregulation of PI3K/Akt/m TOR pathway in GC and the various types of single or dual pathway inhibitors under development that might have a superior role in GC treatment. We also summarize the recent developments in identification of predictive biomarkers and propose use of predictive biomarkers to facilitate more personalized cancer therapy with effective PI3K/Akt/m TOR pathway inhibition.Shikha Satendra Singh Wei Ney Yap Frank Arfuso Shreya Kar Chao Wang Wanpei Cai Arunasalam M Dharmarajan Gautam Sethi Alan Prem Kumar 2015World Journal of Gastroenterology2015,21,43:36
10Role of the renin angiotensin system in diabetic nephropathy显示文摘Diabetic nephropathy has been the cause of lot of mor bidity and mortality in the diabetic population.The renin angiotensin system(RAS) is considered to be involved in most of the pathological processes that result in diabetic nephropathy.This system has var ious subsystems which contribute to the disease pat ho logy.One of these involves angiotensin Ⅱ(Ang Ⅱ) which shows in c reased activity during diabetic nephropathy.This causes hypertrophy of various renal cells and has a pres sor effect on arteriolar smooth muscle resulting in increas ed vascular pressure.Ang Ⅱ also induces inflamm ation,apoptosis,cell growth,migration and differentiation.Monocyte chemoattractant protein-1 production responsible for renal f ibrosis is also regulated by RAS.Polymorphism of angiotensin converting enzym e(ACE) and Angiotensinogen has been shown to have effects on RAS.Available treatment modalities have proven effective in controlling the progression of nephropathy.Various drugs(based on antagonism of RAS) are currently in the market and others are still under trial.Amongst the approved drugs,ACE inhibitors and ang iot ensin receptor blockers(ARBs) are widely used in clinical practice.ARBs are shown to be superior to ACE inhibitors in terms of reducing proteinuria but the combined role of ARBs with ACE inhibitors in diabetic nephropathy is under debate.Tanuj Chawla Deepika Sharma Archana Singh 2010World Journal of Diabetes2010,1,5:34
11A comparative review of HLA associations with hepatitis Band C viral infections across global populations显示文摘Hepatitis B (HBV) and hepatitis C (HCV) viral infection or co-infection leads to risk of development of chronic infection, cirrhosis and hepatocellular carcinoma (HCC). Immigration and globalization have added to the challenges of public health concerns regarding chronic HBV and HCV infections worldwide. The aim of this study is to review existing global literature across ethnic populations on HBV and HCV related human leukocyte antigen (HLA) associations in relation to susceptibility, viral persistence and treatment. Extensive literature search was conducted to explore the HLA associations in HBV and HCV infections reported across global populations over the past decade to understand the knowledge status, weaknesses and strengths of this information in different ethnic populations. HLA DR13 is consistently associated with HBV clearance globally. HLADRB1*11/*12 alleles and DQB1*0301 are associated with HBV persistence but with HCV clearance worldwide. Consistent association of DRB1*03 and *07 is observed with HCV susceptibility and non-responsiveness to HBV vaccination across the population. HLA DR13 is protective for vertical HBV and HCV transmission in Chinese and Italian neonates, but different alleles are associated with their susceptibility in these populations. HLA class Ⅰmolecule interactions with Killer cell immunoglobulin like receptors (KIR) of natural killer (NK) cells modulate HCV infection outcome via regulating immune regulatory cells and molecules. HLA associations with HBV vaccination, interferon therapy in HBV and HCV, and with extra hepatic manifestations of viral hepatitis are also discussed. Systematic studies in compliance with global regulatory standards are required to identify the HLA specific viral epitope, stage specific T cell populations interacting with different HLA alleles during disease progression and viral clearance of chronic HBV or HCV infections among different ethnic populations. These studies would facilitate stage specific therapeutic strategies for clearance of HBV and HCV infections or co-infections across global populations and aid in identification of HBV-HCV combined vaccine. HLA associations of chronic HBV or HCV development with confounding host factors including alcohol, drug abuse, insulin resistance, age and gender are lacking and warrant detailed investigation across global populations.Rashmi Singh Rashmi Kaul Anil Kaul Khalid Khan 2007World Journal of Gastroenterology2007,13,12:31
12Estimation of As and Cu Contamination in Agricultural Soils Around a Mining Area by Reflectance Spectroscopy:A Case Study显示文摘Concentrations of Iron (Fe), As, and Cu in soil samples from the fields near the Baoshan Mine in Hunan Province, China, were analyzed and soil spectral reflectance was measured with an ASD FieldSpec FR spectroradiometer (Analytical Spectral Devices, Inc., USA) under laboratory condition. Partial least square regression (PLSR) models were constructed for predicting soil metal concentrations. The data pre-processing methods, first and second derivatives (FD and SD), baseline correction (BC), standard normal variate (SNV), multiplicative scatter correction (MSC), and continuum removal (CR), were used for the spectral reflectance data pretreatments. Then, the prediction results were evaluated by relative root mean square error (RRMSE) and coefficients of determination (R 2 ). According to the criteria of minimal RRMSE and maximal R 2 , the PLSR models with the FD pretreatment (RRMSE = 0.24, R 2 = 0.61), SNV pretreatment (RRMSE = 0.08, R 2 = 0.78), and BC-pretreatment (RRMSE = 0.20, R 2 = 0.41) were considered as the final models for predicting As, Fe, and Cu, respectively. Wavebands at around 460, 1 400, 1 900, and 2 200 nm were selected as important spectral variables to construct final models. In conclusion, concentrations of heavy metals in contaminated soils could be indirectly assessed by soil spectra according to the correlation between the spectrally featureless components and Fe; therefore, spectral reflectance would be an alternative tool for monitoring soil heavy metals contamination.REN Hong-Yan ZHUANG Da-Fang A.

13Anti-tumor activity of wogonin, an extract from Scutellaria baicalensis, through regulating different signaling pathways显示文摘Wogonin is a plant flavonoid compound extracted from Scutellaria baicalensis(Huang-Qin or Chinese skullcap) and has been studied thoroughly by many researchers till date for its anti-viral, anti-oxidant, anti-cancerous and neuro-protective properties. Numerous experiments conducted in vitro and in vivo have demonstrated wogonin's excellent tumor inhibitory properties. The anticancer mechanism of wogonin has been ascribed to modulation of various cell signaling pathways, including serine-threonine kinase Akt(also known as protein kinase B) and AMP-activated protein kinase(AMPK) pathways, p53-dependent/independent apoptosis, and inhibition of telomerase activity. Furthermore, wogonin also decreases DNA adduct formation with a carcinogenic compound 2-Aminofluorene and inhibits growth of drug resistant malignant cells and their migration and metastasis, without any side effects. Recently, newly synthesized wogonin derivatives have been developed with impressive anti-tumor activity. This review is the succinct appraisal of the pertinent articles on the mechanisms of anti-tumor properties of wogonin. We also summarize the potential of wogonin and its derivatives used alone or as an adjunct therapy for cancer treatment. Furthermore, pharmacokinetics and side effects of wogonin and its analogues have also been discussed.Do Luong Huynh Neelesh Sharma Amit Kumar Singh Simrinder Singh Sodhi ZHANG Jiao-Jiao Raj Kumar Mongre Mrinmoy Ghosh Nameun Kim Yang Ho Park Dong Kee Jeong 2017Chinese Journal of Natural Medicines2017,15,1:32
14Frozen shoulder:A systematic review of therapeutic options显示文摘Frozen shoulder is a common disease which causes significant morbidity. Despite over a hundred years of treating this condition the definition, diagnosis, pathology and most efficacious treatments are still largely unclear. This systematic review of current treatments for frozen shoulder reviews the evidence base behind physiotherapy, both oral and intra articular steroid, hydrodilatation, manipulation under anaesthesia and arthroscopic capsular release. Key areas in which future research could be directed are identified, in particular with regard to the increasing role of arthroscopic capsular release as a treatment.Harpal Singh Uppal Jonathan Peter Evans Christopher Smith 2015World Journal of Orthopedics2015,6,2:33

16Anterior resection for rectal carcinoma-risk factors for anastomotic leaks and strictures显示文摘AIM:To determine the incidence and factors responsible for anastomotic leaks and stricture following anterior resection(AR)and its subsequent management.METHODS:Retrospective analysis of data from 108 patients with rectal carcinoma who underwent AR or low anterior resection(LAR)to identify the various preoperative,operative,and post operative factors that might have influence on anastomotic leaks and strictures.RESULTS:There were 68 males and 40 females with an average of 47 years(range 21-75 years).The median distance of the tumor from the anal verge was 8 cm(range 3-15 cm).Sixty(55.6%)patients underwent handsewn anastomosis and 48(44.4%)were stapled.The median operating time was 3.5 h(range2.0-7.5 h).Sixteen(14.6%)patients had an anastomotic leak.Among these,11 patients required reexploration and five were managed expectantly.The anastomotic leak rate was similar in patients with and without diverting stoma(8/60,13.4%with stoma and 8/48;16.7%without stoma).In 15(13.9%)patients,resection margins were positive for malignancy.Ninteen(17.6%)patients developed anastomotic strictures at a median duration of 8 mo(range 3-20 mo).Among these,15 patients were successfully managed with per-anal dilatation.On multivariate analysis,advance age(>60 years)was the only risk factor for anastomotic leak(P=0.004).On the other hand,anastomotic leak(P=0.00),mucin positive tumor(P =0.021),and lower rectal growth(P=0.011)were found as risk factors for the development of an anastomotic stricture.CONCLUSION:Advance age is a risk factor for an anastomotic leak.An anastomotic leak,a mucin-secreting tumor,and lower rectal growth predispose patients to develop anastomotic strictures.Ashok Kumar Ram Daga Paari Vijayaragavan Anand Prakash Rajneesh Kumar Singh Anu Behari Vinay K Kapoor Rajan Saxena 2011World Journal of Gastroenterology2011,17,11:28
17A Review on Pharmacological and Analytical Aspects of Naringenin显示文摘Flavonoids are a widely distributed group of phytochemicals having benzo-pyrone nucleus, and more than 4,000 different flavonoids have been described and categorized into flavonols, flavones, flavanones, isoflavones, catechins and anthocyanidins. Flavonoids occurs naturally in fruits, vegetables, nuts, and beverages such as coffee, tea, and red wine, as well as in medical herbs. Flavonoids are responsible for the different colors of plant parts and are important constituents of the human diet. Flavanoids have different pharmacological activities, such as antioxidant, anti-allergic, antibacterial, anti-inflammatory, antimutagenic and anticancer activity. Naringenin belongs to the flavanones and is mainly found in fruits(grapefruit and oranges) and vegetables. Pharmacologically, it has anticancer, antimutagenic, anti-inflammatory, antioxidant, antiproliferative and antiatherogenic activities. Naringenin is used for the treatments of osteoporosis, cancer and cardiovascular diseases, and showed lipid-lowering and insulin-like properties. In the present review, detailed pharmacological and analytical aspects of naringenin have been presented, which revealed the impressive pharmacological profile and the possible usefulness in the treatment of different types of diseases in the future. The information provided in this communication will act as an important source for development of effective medicines for the treatment of various disorders.Kanika Patel Gireesh Kumar Singh Dinesh Kumar Patel 2018Chinese Journal of Integrative Medicine2018,24,7:28
18Detection of plant leaf diseases using image segmentation and soft computing techniques显示文摘Agricultural productivity is something on which economy highly depends.This is the one of the reasons that disease detection in plants plays an important role in agriculture field,as having disease in plants are quite natural.If proper care is not taken in this area then it causes serious effects on plants and due to which respective product quality,quantity or productivity is affected.For instance a disease named little leaf disease is a hazardous disease found in pine trees in United States.Detection of plant disease through some automatic technique is beneficial as it reduces a large work of monitoring in big farms of crops,and at very early stage itself it detects the symptoms of diseases i.e.when they appear on plant leaves.This paper presents an algorithm for image segmentation technique which is used for automatic detection and classification of plant leaf diseases.It also covers survey on different diseases classification techniques that can be used for plant leaf disease detection.Image segmentation,which is an important aspect for disease detection in plant leaf disease,is done by using genetic algorithm.Vijai Singh A.K.Misra 2017Information Processing in Agriculture2017,4,1:28
19APACHE II、BISAP、Ranson评分和改良CTSI对急性胰腺炎严重程度(基于Atlanta 2012分类)预测价值的比较显示文摘目的:本研究前瞻性比较了急性生理和慢性健康状况评分(APACHEⅡ)、急性胰腺炎严重程度床边指数(BISAP)、Ranson评分与改良CT严重度指数(CTSI)这四种方法,评估印度北部一家三甲医院急性胰腺炎患者疾病严重程度(基于Atlanta 2012分类)的准确性。方法:前瞻性纳入2015年3月至2016年9月间我院收治的50例急性胰腺炎患者,对所有入组病例进行APACHEⅡ、BISAP和Ranson评分,并基于胰腺对比增加CT进行改良CTSI评估。基于受试者工作特征(ROC)曲线评估这些评分系统预测急性胰腺炎严重程度的最佳阈值和曲线下面积(AUC),并对这些评分系统的预测价值进行前瞻性比较。结果:50例急性胰腺炎患者中14例被评估为重症急性胰腺炎。15例患者出现胰腺坏死,14例出现持续器官功能衰竭,14例需要收治重症监护室(ICU)。改良CTSI对重症急性胰腺炎、胰腺坏死、器官衰竭、入住ICU的预测价值均为最高,其AUC分别为0.919、0.993、0.893和0.993。APACHEⅡ对重症急性胰腺炎和器官衰竭的预测价值均仅次于改良CTSI,其AUC分别为0.934和0.931。APACHEⅡ对胰腺坏死、器官衰竭、入住ICU的预测具有较高的敏感性(分别为93.33%、92.86%和92.31%)和阴性预测值(分别为96.15%、96.15%和95.83%)。结论:APACHEⅡ是预测急性胰腺炎严重程度的一项有效的评估系统,有助于筛选出病情危重、需要早期复苏和尽快转诊上级医院的急性胰腺炎患者,尤其在一些医疗资源匮乏的发展中国家。Anubhav Harshit Kumar Mahavir Singh Griwan 2018Gastroenterology Report2018,6,2:27
