| 1 | 帕博利珠单抗单用或与放疗联用治疗转移性非小细胞肺癌:两个随机试验的汇总分析显示文摘背景放疗可以提高整个机体对免疫治疗的应答。在Ⅱ期PEMBRO-RT研究和Ⅰ/Ⅱ期MDACC研究中,患有转移性非小细胞肺癌(NSCLC)的患者被随机分配入组,接受免疫治疗(帕博利珠单抗)+放疗联合疗法,或免疫治疗单一疗法。当上述2个研究单独分析时,联合疗法组显示出潜在获益。由于每个研究的样本量较小,缓解率和结局并未显示出统计学意义,然而却有显著的临床获益。因此,本研究进行汇总分析,来判断放疗是否会改善转移性NSCLC患者的免疫治疗应答。方法PEMBRO-RT和MDACC研究纳入标准:患者年龄≥18岁,患有转移性NSCLC,且有≥1处未经放疗照射的病灶,以便进行射野外应答监测。PEMBRO-RT研究纳入曾接受过化疗患者,MDACC研究纳入曾接受过治疗或新诊断患者。2个研究中的患者均未接受过免疫治疗。在PEMBRO-RT研究中患者被等比例随机分配入组,并根据吸烟状态进行分层(分为<10年组和≥10年组)。MDACC研究的患者根据放疗计划可行性被等比例随机分配入2个受试组。由于联合治疗组的干预本质,每个研究中的放疗均不适用盲法。在2个研究中,不论是否进行放疗,均静脉滴入帕博利珠单抗(每3周200 mg)。在PEMBRO-RT研究中,在放疗(24 Gy 3次分割照射)结束后1周给予第1剂帕博利珠单抗。在MDACC研究中,在第1次放疗(50 Gy 4次分割照射或45 Gy 15次分割照射)同时给予帕博利珠单抗。仅检测未经照射病灶的应答。本研究的终点为最佳射野外(远隔)应答率(ARR)、最佳射野外疾病控制率(ACR)、12周时ARR、12周时ACR、无进展生存期(PFS)和总生存期(OS)。2个研究的意向治疗(ITT)人群均纳入分析。PEMBRO-RT研究(NCT02492568)和MDACC研究(NCT02444741)均在ClinicalTrials.gov上注册。发现纳入148例患者,76例接受帕博利珠单抗治疗,72例接受帕博利珠单抗+放疗治疗。所有患者随访时间中位数为33个月[四分位距(IQR):32.4~33.6]。148例患者中124例(84%)组织学特征为非鳞癌,111例(75%)患者曾经接受过化疗。组间没有基线特征差异,包括PD-L1表达状态和转移灶体积。最常见的照射部位为肺转移灶(39%,28/72)、胸腔内淋巴结(21%,15/72)和非原发灶(17%,12/72)。帕博利珠单抗组和联合治疗组的最佳ARR分别为19.7%(15/76)和41.7%(30/72),OR=2.96,95%CI:1.42~6.20,P=0.0039;最佳ACR分别为43.4%(33/76)和65.3%(47/72),OR=2.51,95%CI:1.28~4.91,P=0.0071;PFS中位数分别为4.4(IQR:2.9~5.9)和9.0个月(IQR:6.8~11.2),HR=0.67,95%CI:0.45~0.99,P=0.045;OS中位数分别为8.7(IQR:6.4~11.0)和19.2个月(IQR:14.6~23.8),OR=0.67,95%CI:0.54~0.84,P=0.0004。在汇总分析中没有发现新的安全问题。解读帕博利珠单抗免疫疗法+放疗显著提高转移性NSCLC患者的应答和改善治疗结局。这些结果需要在三期临床试验中进行验证。 | 陈大卫(翻译) 于金明(校对) Willemijn S M E Theelen Vivek Verma Brian P Hobbs Heike M U Peulen Joachim G J V Aerts Idris Bahce Anna Larissa N Niemeijer Joe Y Chang Patricia M de Groot Quynh-Nhu Nguyen Nathan I Comeaux George R Simon Ferdinandos Skoulidis Steven H Lin Kewen He Roshal Patel John Heymach Paul Baas James W Welsh | 2021 | 中华肿瘤防治杂志2021,28,24: | 49 |
| 2 | Molecular mechanisms of viral hepatitis induced hepatocellular carcinoma显示文摘Chronic infection with viral hepatitis affects half a billion individuals worldwide and can lead to cirrhosis,cancer,and liver failure.Liver cancer is the third leading cause of cancer-associated mortality,of which hepatocellular carcinoma(HCC)represents 90%of all primary liver cancers.Solid tumors like HCC are complex and have heterogeneous tumor genomic profiles contributing to complexity in diagnosis and management.Chronic infection with hepatitis B virus(HBV),hepatitis delta virus(HDV),and hepatitis C virus(HCV)are the greatest etiological risk factors for HCC.Due to the significant role of chronic viral infection in HCC development,it is important to investigate direct(viral associated)and indirect(immune-associated)mechanisms involved in the pathogenesis of HCC.Common mechanisms used by HBV,HCV,and HDV that drive hepatocarcinogenesis include persistent liver inflammation with an impaired antiviral immune response,immune and viral protein-mediated oxidative stress,and deregulation of cellular signaling pathways by viral proteins.DNA integration to promote genome instability is a feature of HBV infection,and metabolic reprogramming leading to steatosis is driven by HCV infection.The current review aims to provide a brief overview of HBV,HCV and HDV molecular biology,and highlight specific viral-associated oncogenic mechanisms and common molecular pathways deregulated in HCC,and current as well as emerging treatments for HCC. | Simmone D'souza Keith CK Lau Carla S Coffin Trushar R Patel | 2020 | World Journal of Gastroenterology2020,26,38: | 25 |
| 3 | Antidiabetic and in vitro antioxidant potential of Hybanthus enneaspermus(Linn) F.Muell in streptozotocin—induced diabetic rats显示文摘Objective:To evaluate antidiabetic and antioxidant potential of Hybanthus enneaspermus in different models.Methods:The oral glucose tolerance test(OGTT) and normoglycemic effect of alcoholic extract of Hybanthus enneaspermus(AHE) were evaluated at a dose of 125,250 and 500mg/kg p.o.while hypoglycemic activity and effect on body weight were tested at 250 and 500 mg/kg p.o.per day for 21 days in Streptozotocin(STZ) induced diabetic rats.Further,glucose uptake by hemidiaphram was also evaluated.The total polyphenolic and flavonoid were determined and their correlation with various antioxidant assays was also determined.Results:The results showed high level of phenolic content in AHE.AHE also exhibited higher total antioxidant capacity,good reducing power and a significant scavenger of reactive oxygen species like DPPH radical,nitric oxide,hydrogen peroxide and deoxyribose.Furthermore there was a significant increase in the body weight and decrease in the blood glucose level on treatment with the AHE.AHE increased glucose uptake on isolated rat hemi-diaphragm compared to control group.Conclusions:AHE reduce blood glucose level in STZ-induced diabetic model.It does not show significant effect in normoglycemic study but showes significant effect in OGT.AHE has significant antioxidant activity,which may be attributed to high phenolic content. | Patel DK Kumar R Prasad SK Sairam K Hemalatha S | 2011 | Asian Pacific Journal of Tropical Biomedicine2011,1,4: | 22 |
| 4 | Management of pancreaticobiliary disease using a new intra-ductal endoscope:The Texas experience显示文摘AIM:To evaluate a new single-operator mini-endoscope, Spyglass,for its performance,feasibility and safety in the management of pancreaticobiliary disease. METHODS:In a multicenter retrospective analysis of patients undergoing intraductal endoscopy,we evaluated 128 patients(71 men,mean age 57.6 years).Indications were therapeutic(TX)in 72(56%) and diagnostic(DX)in 56(44%). RESULTS:Peroral endoscopy was performed in 121 and percutaneous in seven.TX indications included CBD stones in 41,PD stones in six,and biliary strictures in 25.DX indications included abnormal LFT’s in 15, abnormal imaging in 38 and cholangiocarcinoma staging in three.Visualization of the stone(s)was considered good in 31,fair in six,and poor in four. Advancement of the electrohydraulic lithotripsy probe was not possible in three patients and proper targeting of the lesion was partial in four patients.A holmium laser was used successfully in three patients.Ductal clearance was achieved in 37 patients after one procedure and in four patients after two procedures.Diagnosis of biliary strictures was modified in 20/29 and confirmed to be malignant in 10/23.Of the modified patients,no diagnosis was available in 17.Spyglass demonstrated malignancy in 8/17 and non-malignancy in nine.Suspected pathology by imaging studies and abnormal LFT’s was modified in 43/63(66%).Staging of cholangiocarcinoma demonstrated multicentric cholangiocarcinoma in 2/3.There was no morbidity associated with the use of Spyglass. CONCLUSION:Spyglass Spyscopeis a first generation, single operator miniature endoscope that can evaluate and treat various biliary and pancreatic tract diseases. | Douglas S Fishman Paul R Tarnasky Sandeep N Patel Isaac Raijman | 2009 | World Journal of Gastroenterology2009,15,11: | 22 |
| 5 | Diabetes mellitus:An overview on its pharmacological aspects and reported medicinal plants having antidiabetic activity显示文摘Diabetes mellitus is not a single disease but is a group of metabolic disorders affecting a huge numlier of population in the world.It is mainly characterized by chronic hyperglycemia,resulting from defects in insulin secretion or insulin action.It is predicated that the number of diabetes person in the world could reach upto 366 million by the year 2030.Even though the cases of diabetes are increasing day by day,except insulin and oral hypoglycemic drugs no other way of treatment has been successfully developed so far.Thus,the objective of the present review is to provide an insight over the pathophysiological and etiological aspects of diabetes mellitus along with the remedies available for this metabolic disorder.The review also contains brief idea about diabetes mellitus and the experimental screening model with their relevant mechanism and significance mainly used nowadays.Alloxan and streptozotocin are mainly used for evaluating the antidiabetic activity of a particular drug.This review contain list of medicinal plants which have been tested for their antidiabetic activity in the alloxan induced diabetic rat model.From the available data in the literature,it was found that plant having antidiabetic activity is mainly due to the presence of the secondary metabolite.Thus,the information provided in this review will help the researchers for the development of an alternative methods rather than insidin and oral hypoglycemic agents for the treatment of diabetes niellitus,which will minimize the complication associated with the diabetes and related disorder. | Patel DK Kumar R Laloo D Hemalatha S | 2012 | Asian Pacific Journal of Tropical Biomedicine2012,2,5: | 17 |
| 6 | An overview on antidiabetic medicinal plants having insulin mimetic property显示文摘Diabetes mellitus is one of the common metabolic disorders acquiring around 2.8%of the world's population and is anticipated to cross 5.4%by the year 2025.Since long back herbal medicines have been the highly esteemed source of medicine therefore,they have become a growing part of modern,high-tech medicine.In view of the above aspects the present review provides profiles of plants(65 species) with hypoglycaemic properties,available through literature source from various database with proper categorization according to the parts used,mode of reduction in blood glucose(insulinomimetic or insulin secretagugues activity) and active phyloconsliluents having insulin mimetics activity.From the review it was suggested that,plant showing hypoglycemic potential mainly belongs to the family Leguminoseae,Lamiaceae,Liliaceae,Cucurbitaceae, Asteraceae,Moraceae,Rosaceae and Araliaceae.The most active plants are Allium sativum. Gymnema sylvestre,Citrullus colocynthis,Trigonella foenum greacum,Momordica charantia and Ficuts bengalensis.The review describes some new bioactive drugs and isolated compounds from plants such as roseoside,epigallocatechin gallate,beta-pyrazol-1-ylalanine,cinchonain Ib,leucocyandin 3-O-beta-d-galactosyl cellobioside,leucopelargonidin-3- O-alpha-L rhamuoside,glycyrrhetinic acid,dehydrotrametenolic acid,strictinin,isostrictinin,pedunculagin, epicatechin and christinin-A showing significant insulinomimetic and antidiabetic activity with more efficacy than conventional hypoglycaemic agents.Thus,from the review majorly,the antidiabetic activity of medicinal plants is attributed to the presence of polyphenols,flavonoida, terpenoids,coumarins and other constituents which show reduction in blood glucose levels.The review also discusses the management aspect of diabetes mellitus using these plants and their active principles. | Patel DK Prasad SK Kumar R Hemalatha S | 2012 | Asian Pacific Journal of Tropical Biomedicine2012,2,4: | 15 |

| 10 | Coagonist of glucagon-like peptide-1 and glucagon receptors ameliorates kidney injury in murine models of obesity and diabetes mellitus显示文摘AIM To investigate the role of glucagon-like peptide-1(GLP-1)/glucagon receptors coagonist on renal dysfunction associated with diabetes and obesity. METHODS Chronic high-fat diet fed C57 BL/6 J mice, streptozotocintreated high-fat diet fed C57 BL/6 J mice and diabeticC57 BLKS/J db/db mice were used as models of diabetes-induced renal dysfunction. The streptozotocintreated high-fat diet fed mice and db/db mice were treated with the GLP-1 and glucagon receptors coagonist(Aib2 C24 Chimera2, 150 μg/kg, sc) for twelve weeks, while in chronic high-fat diet fed mice, coagonist(Aib2 C24 Chimera2, 150 μg/kg, sc) treatment was continued for forty weeks. Kidney function, histology, fibrosis, inflammation, and plasma biochemistry were assessed at the end of the treatment. RESULTS Coagonist treatment decreased body weight, plasma lipids, insulin resistance, creatinine, blood urea nitrogen, urinary albumin excretion rate and renal lipids. In kidney, expression of lipogenic genes(SREBP-1 C, FAS, and SCD-1) was decreased, and expression of genes involved in β-oxidation(CPT-1 and PPAR-α) was increased due to coagonist treatment. In plasma, coagonist treatment increased adiponectin and FGF21 and decreased IL-6 and TNF-?. Coagonist treatment reduced expression of inflammatory(TNF-α, MCP-1, and MMP-9) and pro-fibrotic(TGF-β, COL1 A1, and α-SMA) genes and also improved histological derangement in renal tissue.CONCLUSION Coagonist of GLP-1 and glucagon receptors alleviated diabetes and obesity-induced renal dysfunction by reducing glucose intolerance, obesity, and hyperlipidemia. | Vishal J Patel Amit A Joharapurkar Samadhan G Kshirsagar Brijesh K Sutariya Maulik S Patel Hiren M Patel Dheerendra K Pandey Rajesh H Bahekar Mukul R Jain | 2018 | World Journal of Diabetes2018,9,6: | 5 |
