| 1 | Staging accuracy of esophageal cancer by endoscopic ultrasound:A meta-analysis and systematic review显示文摘AIM: To evaluate the accuracy of endoscopic ultrasound (EUS) in the staging of esophageal cancer. METHODS: Only EUS studies confirmed by surgery were selected. Articles were searched in Medline and Pubmed. Two reviewers independently searched and extracted data. Meta-analysis of the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios, and diagnostic odds ratio. Pooling was conducted by both the Mantel-Haenszel method (fixed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran’s Q test based upon inverse variance weights. RESULTS: Forty-nine studies (n = 2558) which met the inclusion criteria were included in this analysis. Pooled sensitivity and specificity of EUS to diagnose T1 was 81.6% (95% CI: 77.8-84.9) and 99.4% (95% CI: 99.0-99.7), respectively. To diagnose T4, EUS had a pooled sensitivity of 92.4% (95% CI: 89.2-95.0) and specificity of 97.4% (95% CI: 96.6-98.0). With Fine Needle Aspiration (FNA), sensitivity of EUS to diagnose N stage improved from 84.7% (95% CI: 82.9-86.4) to 96.7% (95% CI: 92.4-98.9). The P value for the χ2 test of heterogeneity for all pooled estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity in accurately diagnosing the TN stage of esophageal cancer. EUS performs better with advanced (T4) than early (T1) disease. FNA substantially improves the sensitivity and specificity of EUS in evaluating N stage disease. EUS should be strongly considered for staging esophageal cancer. | Srinivas R Puli Jyotsna BK Reddy Matthew L Bechtold Daphne Antillon Jamal A Ibdah Mainor R Antillon | 2008 | World Journal of Gastroenterology2008，14，10： | 55 |
| 2 | How good is endoscopic ultrasound for TNM staging of gastric cancers? A meta-analysis and systematic review显示文摘AIM: To evaluate the accuracy of endoscopic ultrasound (EUS) for staging of gastric cancers. METHODS: Only EUS studies confirmed by surgery were selected. Only studies from which a 2 × 2 table could be constructed for true positive, false negative, false positive and true negative values were included. Articles were searched in Medline, Pubmed, Ovid journals, Cumulative index for nursing & allied health literature, International pharmaceutical abstracts, old Medline, Medline nonindexed citations, and Cochrane control trial registry. Two reviewers independently searched and extracted data. The differences were resolved by mutual agreement. 2 × 2 tables were constructed with the data extracted from each study. Meta-analysis for the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specifi city, likelihood ratios, and diagnostic odds ratio. Pooling was conducted by both the Mantel-Haenszel method (fi xed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran's Q test based upon inverse variance weights. RESULTS: Initial search identified 1620 reference articles and of these, 376 relevant articles were selected and reviewed. Twenty-two studies (n = 1896) which met the inclusion criteria were included in this analysis. Pooled sensitivity of T1 was 88.1% (95% CI: 84.5-91.1) and T2 was 82.3% (95% CI: 78.2-86.0). For T3, pooled sensitivity was 89.7% (95% CI: 87.1-92.0). T4 hada pooled sensitivity of 99.2% (95% CI: 97.1-99.9). For nodal staging, the pooled sensitivity for N1 was 58.2% (95% CI: 53.5-62.8) and N2 was 64.9% (95% CI: 60.8-68.8). Pooled sensitivity to diagnose distant metastasis was 73.2% (95% CI: 63.2-81.7). The P for chi-squared heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION: EUS results are more accurate with advanced disease than early disease. If EUS diagnoses advanced disease, such as T4 disease, the patient is 500 times more likely to have true anatomic stage of T4 disease. | Srinivas Reddy Puli Jyotsna Batapati Krishna Reddy Matthew L Bechtold Mainor R Antillon Jamal A Ibdah | 2008 | World Journal of Gastroenterology2008，14，25： | 33 |

| 4 | Endoscopic ultrasound:It’s accuracy in evaluating mediastinal lymphadenopathy? A meta-analysis and systematic review显示文摘AIM:To evaluate the accuracy of endoscopic ultrasound (EUS), EUS-fine needle aspiration (FNA) in evaluating mediastinal lymphadenopathy. METHODS:Only EUS and EUS-FNA studies confirmed by surgery or with appropriate follow-up were selected. Articles were searched in Medline, Pubmed, and Cochrane control trial registry. Only studies from which a 2 × 2 table could be constructed for true positive, false negative, false positive and true negative values were included. Two reviewers independently searched and extracted data. The differences were resolved by mutual agreement. Meta-analysis for the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios, and diagnostic odds ratios. Pooling was conducted by both Mantel-Haenszel method (fixed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran’s Q test based upon inverse variance weights. RESULTS:Data was extracted from 76 studies (n = 9310) which met the inclusion criteria. Of these, 44 studies used EUS alone and 32 studies used EUS-FNA. FNA improved the sensitivity of EUS from 84.7% (95% CI:82.9-86.4) to 88.0% (95% CI:85.8-90.0). With FNA, the specificity of EUS improved from 84.6% (95% CI:83.2-85.9) to 96.4% (95% CI:95.3-97.4). The P forchi-squared heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION:EUS is highly sensitive and specific for the evaluation of mediastinal lymphadenopathy and FNA substantially improves this. EUS with FNA should be the diagnostic test of choice for evaluating mediastinal lymphadenopathy. | Srinivas R Puli Jyotsna Batapati Krishna Reddy Matthew L Bechtold Jamal A Ibdah Daphne Antillon Shailender Singh Mojtaba Olyaee Mainor R Antillon | 2008 | World Journal of Gastroenterology2008，14，19： | 10 |
| 5 | Self-Healing Concrete with Crystalline Admixture——A Review显示文摘The scope of the present paper is to understand the effects of crystalline admixture on the selfhealing capacity of the cementitious composites. Previous studies were examined and a conclusion was drawn to the effect that different additives to crystalline admixture tend to improve self-healing of concrete for larger cracks. It is recommended that initial treatment with chemical admixture can stimulate and heal further cracks and it has the better repeatability trend in mixing with the concretes and mechanical recovery is possible even under repetitive preloading. Effective self-healing with chemical admixtures even under open-air exposure, leads to study the importance of a service ability design parameter including the maximum allowable crack width by repeatability analysis as a function of the exposure with the concept of sealable crack width. | A Ravitheja Dr T Chandra Sekhara Reddy Dr C Sashidhar | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，5： | 6 |
| 6 | Fundus changes in pregnancy induced hypertension显示文摘AIM: To determine the prevalence of retinal changes in pregnancy induced hypertension (PIH) and any association between the retinal changes and blood pressure, proteinuria, and severity of the disease. METHODS: All the patients admitted with diagnosis of PIH were included in this study. Age, race, gravida, gestation period, blood pressure, and proteinuria were noted from the case records. After taking history for any eye symptoms, fundus examination was done after dilating the pupils with direct ophthalmoscope in the ward itself. All the findings were noted on a data sheet, and were analyzed using SPSS programme. RESULTS: A total of 78 patients of PIH were examined. Majority (75.6%) were Malays. The mean age of patients was 30.2 years (range 21-45 years). The gestation period ranged from 25 weeks to 41 weeks; 34 (43.5%) were primi gravida. Thirty (38.4%) patients had mild preeclampsia, 46 (59%) had severe preeclampsia and 2(2.5%) had eclampsia. Retinal changes (hypertensive retinopathy) were noted in 46 (59%) patients --- grade I in 41 (52.6%) and grade II in 5 (6.4%). Haemorrhages or exudates or retinal detachment were not seen in any patient. There was statistically significant positive association of retinal changes and blood pressure (P =0.001), proteinuria (P =0.018) and severity of the PIH (P =0.024). CONCLUSION: Retinal changes (grade I and II hypertensive retinopathy) were seen in 59% of patients with PIH and they were significantly associated with blood pressure, proteinuria and severity of the disease. Fundus examination helps in assessing the severity of PIH. | Sagili Chandrasekhara Reddy Sivalingam Nalliah Sheila Rani a/pKovil George Tham Seng Who | 2012 | International Journal of Ophthalmology(English edition)2012，5，6： | 3 |
| 7 | Ceftazidime resistance in Burkholderia pseudomallei:First report from India显示文摘Melioidosis,a disease of public health importance in Southeast Asia and Northern Australia,of late has shown an increasing trend in India,particularly Southern India.We describe a ease of a 39-year-old diabetic patient with left elbow septic arthritis,multiple liver,splenic abscesses, pneumonia,pleural effusion,followed by sepsis syndrome.Blood cultures and culture of the joint aspirate yielded pure growth of Burkholderia psettdomallei(B.pesudomallei),sensitive to carbapenem,co-trimoxazole and resistant to ceftazidime.The patient was successfully treated with imipenem- cilastin.He was discharged on co-trimoxazole to complete the 24 weeks course and follow-up has continued to date.The patient continues to remain asymptomatic.The case re-emphasizes the need to monitor the trend of B.pseudomallei in India,particularly the development of ceftazidime resistance,which incidentally is the drug of choice. | Bijayini Behera TLVD Prasad Babu A Kamalesh Gangadhar Reddy | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，4： | 3 |
| 8 | Budd-Chiari syndrome:A single-center experience显示文摘AIM:To investigate challenges,risk factors,prognostic indicators,and treatment outcomes associated with Budd-Chiari syndrome(BCS)at a tertiary care center.METHODS:A retrospective cohort study was conducted at the University of Pennsylvania in patients with a diagnosis of BCS or hepatic vein thrombosis.All patients receiving care at the University of Pennsylvania,and who had at least 2 clinical encounters in the University of Pennsylvania Health system from January1,2008 to September 10,2013 were eligible for study inclusion.Data were extracted from the electronic medical record of each patient,and recorded in a secure Research Electronic Data Capture database.Logistic regression analyses were applied to identify predictors of outcome of liver transplant(LT)or death.RESULTS:Between January 1,2008 and September10,2013,forty-seven patients were identified.Median age was 42.4 years.Thirty-one(66.0%)were women.A majority were Caucasian(68.1%).At diagnosis,43(91.5%)patients had ascites,27(57.4%)patients had a hematologic disorder associated with a hypercoagulable state and 26(55.3%)had cirrhosis.Forty(85.1%)patients were on anticoagulation(AC),30(63.8%)of whom were maintained on warfarin.Two patients(4.3%)underwent thrombolytic therapy.A transjugular intrahepatic portosystemic shunt(TIPS)was placed in21(44.7%)patients,19(90.5%)of whom were also on AC.Twenty-one(44.7%)received AC alone.Over a median of 974 d,8(17.0%)patients received LT,and10(21.3%)died.The median time from listing to death was 26 mo[interquartile range(IQR)=16,65)].TIPS with AC was utilized more frequently in younger patients(P=0.02).Age,cirrhosis and chronic kidney disease(CKD)were significant predictors of LT or death.CONCLUSION:AC alone was employed as frequently as TIPS with AC,though the latter was used more frequently in younger patients with polycythemia vera.There were no significant differences in treatment outcome regardless of the therapeutic intervention employed.Significant predictors of poor prognosis included age,cirrhosis and CKD. | Tanya M Pavri Alan Herbst Rajender Reddy Kimberly A Forde | 2014 | World Journal of Gastroenterology2014，20，43： | 2 |
| 9 | Influence of Rotational Speed on Microstructure and Mechanical Properties of Dissimilar Metal AISI 304-AISI 4140 Continuous Drive Friction Welds显示文摘Fundamental investigation of continuous drive friction welding of austenitic stainless steel (AISI 304) and low alloy steel (AISI 4140) is described. The emphasis is made on the influence of rotational speed on the microstructure and mechanical properties such as hardness, tensile strength, notch tensile strength and impact toughness of the dissimilar joints. Hardness profiles across the weld show the interface is harder than the respective parent metals. In general, maximum peak hardness is observed on the stainless steel side, while other peak hardness is on the low alloy steel side. A trough in hardness distribution in between the peaks is located on the low alloy steel side. Peak hardness on the stainless steel and low alloy steel side close to the interface increases with a decrease in rotational speed. All transverse tensile joints fractured on stainless steel side near the interface. Notch tensile strength and impact toughness increase with increase in rotational speed up to 1 500 r/min and decrease thereafter. The mechanism of influence of rotational speed for the observed trends is discussed in the torque, displacement characteristics, heat generation, microstructure, fractography and mechanical properties. | G Subhash Chander G Madhusudhan Reddy A Venugopal Rao | 2012 | Journal of Iron and Steel Research(International)2012，19，10： | 2 |
| 10 | Dynamic Fracture Toughness of Armour Grade Quenched and Tempered Steel Joints Fabricated Using Low Hydrogen Ferritic Fillers显示文摘The armour grade quenched and tempered steel joints fabricated using low hydrogen ferritic steel (LHF) filler exhibited superior joint efficiency owing to preferential ferrite microstructure in the welds and also they offered required resistance to HIC. However, the combat vehicles used in military operations will be required to operate under a wide range of road conditions ranging from first class to cross country. Structural components in combat vehicles are subjected to dynamic loading with high strain rates during operation. Stress loadings within the vehicle hull of these vehicles are expected to fluctuate considerably and structural cracking especially in welds during the service life of these vehicles can lead to catastrophic failures. Under these conditions, fracture behaviour of high strain rate sensitive structural steels can be better understood by dynamic fracture toughness (K1d). Hence, an attempt was made to study dynamic fracture toughness of the armour grade quenched and tempered steel and their welds fabricated using LHF consumables. The experimental results indicate that the K1d values of the joints fabricated by shielded metal arc welding (SMAW) are higher than those of the joints fabricated using flux cored arc welding (FCAW) process. | G Magudeeswaran V Balasubramanian S Sathyanarayanan G Madhusudhan Reddy A Moitra S Venugopal G Sasikala | 2010 | Journal of Iron and Steel Research(International)2010，17，5： | 2 |
