1Geochemistry and petrogenesis of Jurassic high Sr/low Y granitoids in eastern China: Constrains on crustal thickness显示文摘The Jurassic high Sr/low Y granitoids in eastern China are characterized by high Sr/Y (27-166) and La/Yb (14-66) ratios, low abundance in Y (6-21μg/g) and Yb (0.5-2.0μg/g), comparable with those of adakites defined by Defant et al. Thus, they were recently considered as adakitic rocks by some researchers. Compared with the typical adakites in circum-Pacific margins, however, these high Sr/low Y granitoids have higher K2O (-3.5%) but lower A12O3 (-16.0%) as well as lower Mg#(-38) and δSrN (-1.23) values. Furthermore, they show relatively flat HREE patterns with Y/Yb values of -10 close to the chondritic value. These geochemical characteristics indicate a residue mineral assemblage of hornblende, garnet and plagioclase for these high Sr/low Y granitoids melt. Thus, they were generated by partial melting at 9-13 kbar (30-45 km in depth), similar to the Archaean high-Al TTG rather than the modern adakites. Generation of these high Sr/low Y granitoids cannot be considered as evidence for a thickenedGe, XY Li, XH Chen, ZG Li, WP 2002Chinese Science Bulletin2002,47,11:51
2Role of surgery in colorectal cancer liver metastases显示文摘Colorectal carcinoma(CRC)is the third most common cancer,and approximately 35%-55%of patients with CRC will develop hepatic metastases during the course of their disease.Surgical resection represents the only chance of long-term survival.The goal of surgery should be to resect all metastases with negative histological margins while preserving sufficient functional hepatic parenchyma.Although resection remains the only chance of long-term survival,management strategies should be tailored for each case.For patients with extensive metastatic disease who would otherwise be unresectable,the combination of advances in medical therapy,such as systemic chemotherapy(CTX),and the improvement in surgical techniques for metastatic disease,have enhanced prognosis with prolongation of the median survival rate and cure.The use of portal vein embolization and preoperative CTX may also increase the number of patients suitable for surgical treatment.Despite current treatment options,many patients still experience a recurrence after hepatic resection.More active systemic CTX agents are beingused increasingly as adjuvant therapy either before or after surgery.Local tumor ablative therapies,such as microwave coagulation therapy and radiofrequency ablation therapy,should be considered as an adjunct to hepatic resection,in which resection cannot deal with all of the tumor lesions.Formulation of an individualized plan,which combines surgery with systemic CTX,is a necessary task of the multidisciplinary team.The aim of this paper is to discuss different approaches for patients that are treated due to CRC liver metastasis.?zgür Akgül Erdin? ?etinkaya ?iyar Ers?z Mesut Tez 2014World Journal of Gastroenterology2014,20,20:40

5Effect of harmless acute pancreatitis score, red cell distribution width and neutrophil/lymphocyte ratio on the mortality of patients with nontraumatic acute pancreatitis at the emergency department显示文摘BACKGROUND: Harmless acute pancreatitis score(HAPS), neutrophile/lymphocyte ratio and red blood cell distribution width(RDW) are used to determine the early prognosis of patients diagnosed with nontraumatic acute pancreatitis in the emergency department(ED).METHODS: Patients diagnosed with acute pancreatitis(K 85.9) in the ED according to the ICD10 coding during one year were included in the study. Patients with chronic pancreatitis and those who had missing data in their files were excluded from the study. Patients who did not have computed tomography(CT) in the ED were not included in the study.RESULTS: Ultimately, 322 patients were included in the study. The median age of the patients was 53.1(IQR=36–64). Of the patients, 68.1%(n=226) had etiological causes of the biliary tract. The mortality rate of these patients within the first 48 hours was 4.3%(n=14). In the logistic regression analysis performed by using Balthazar classification, HAPS score, RDW, neutrophile/lymphocyte ratio, age, diabetes mellitus and systolic blood pressure, the only independent variable in determining mortality was assigned as Balthazar classification(OR: 15; 95% CI: 3.5 to 64.4).CONCLUSIONS: HAPS, neutrophile/lymphocyte ratio and RDW were not effective in determining the mortality of nontraumatic acute pancreatitis cases within the first 48 hours. The only independent variable for determining the mortality was Balthazar classifi cation.Bedia Gülen Ertan Sonmez Serpil Yaylaci Mustafa Serinken Cenker Eken Ali Dur Figen Tunali Turkdogan ?zgür S?güt 2015World Journal of Emergency Medicine2015,6,1:13

7Prognostic efficacy of inflammation-based markers in patients with curative colorectal cancer resection显示文摘AIM To evaluate the prognostic significance of neutrophilto-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), lymphocyte-to-monocyte ratio(LMR), and prognostic nutritional index(PNI) and other clinicopathological factors in patients undergoing curative resection of colon cancer.METHODS183 patients with histologically proven colorectal cancer who had undergone potentially curative resection between 2010 and 2016 at Ankara Numune Training and Research Hospital were retrospectively analyzed and clinicopathological characteristics included age, sex, tumor type, grade, size and localization, the number of metastatic and total number of lymph nodes removed, vascular and perineural invasion of the tumor, TNM stages, tumor marker levels(CEA, CA19-9, AFP, CA-125, CA15-3), complete blood counts, albumin levels, overall survival(months), NLR, PLR, LMR and PNI ratios were retrospectively reviewed and analyzed from the electronic database. The primary outcome measure was overall survival.RESULTS Regarding overall survival, on univariate analysis the following variables were significantly associated with poor outcome following resection: T-stage(P = 0.037), lymph node invasion(P = 0.037), cancer stage(P = 0.034), CEA(P = 0.042), CA19-9(P = 0.004), and PNI(P = 0.001). To evaluate the independent prognostic value, multivariate Cox proportional hazard analysis to control for other prognostic factors was used. Using cancer-specific death as an end point for NLR, PLR, LMR, PNI and CA19-9 the optimal cut off values were calculated by ROC analysis. Regarding overall survival, on multivariate analysis high CA19-9(HR = 1.001, 95%CI: 1.00-1.002, P = 0.012) and low PNI(HR = 0.938, 95%CI: 0.891-0.987, P = 0.014) were the only variables independently associated with shortened overall survival. Patients with a PNI < 35 had a median OS of 52.25 mo. In contrast, patients with an PNI > 35 had a median OS of 66 mo. Patients with a CA 19-9 < 17 had a median OS of 66 mo and in patients with a CA19-9 > 17 had a median OS of 53.76 mo.CONCLUSION This study shows that decrease in the PNI and increase in CA 19-9 is associated with poor survival in patients with resectable colon cancer.özgür Akgül Erdinc Cetinkaya Metin Yalaza Sabri özden Mesut Tez 2017World Journal of Gastrointestinal Oncology2017,9,7:11
8Determination of global mean sea surface WHU2000 using multi-satellite altimetric data显示文摘In this study, the overall editing criteria for altimetric data are considered and the geophysical correction models is improved. The datum for various altimetric data is also unified and the method of a full-combined crossover adjustment for different altimetric tracks is used to improve the radial orbits of Geosat, ERS-1 and ERS-2 data. In addition, the method for determining mean sea surface (MSS) by using multi-altimetric data is developed. The data used to compute WHU2000 MSS include 7-year Topex/Poseidon data (cycles 11-249), 2-year Geosat ERM data (cycles 1-44), 5-year ERS2 data (cycles 1-52) and all ERS-1 168-day data. The WHU2000 MSS is determined with a grid resolution of 2’×2’ within the ± 82° latitude and its precision is better than 0.05 m. Comparing WHU 2000MSS with 3.75’×3.75’ CLS_SHOM98.2 MSS, 3’×3’ GFZ MSS95A and 3.75’×3.75’ OSU MSS95, as external checks, the corresponding standard deviation (STD) of their differences is 0.090 m, 0.211 m and 0.079 m respectively.Jiang, WP Li, JC Wang, ZG 2002Chinese Science Bulletin2002,47,19:9

13Urine products of bone breakdown as markers of bone resorption and clinical usefulness of urinary hydroxyproline:an overview显示文摘Purpose The purpose of this study is to review the urine products of bone breakdown as markers of bone resorption and usefulness of urinary hydroxyproline. Data Related researches published in 1985 -2000 were systematically reviewed. Results Bone markers could be used for early diagnosis of bone metabolic diseases. Biochemical markers of bone resorption that reflect osteoclast activity and/or collagen degradation provide a new and potentially important clinical tool for the assessment and monitoring of bone metabolism. Assessment of bone resorption can be achieved with measurement of urinary hydroxylysine glycosides, urinary excretion of the collagen pyridinium cross-links, urinary excretion of type I collagen telopeptide breakdown products (cross-linked telopeptides) and urinary hydroxyproline. Conclusion Urinary hydroxyproline has been in use as a marker of bone resorption, but it lacks sensitivity and specificity. It is a modified aminoacid that is a metabolic product of collagen breakdown.Hydroxyproline may be released either free or with fragments of the collagen molecule attached during bone resorption, and it is also liberated by the breakdown of complement and nonskeletal collagen.Baris Simsek zgülKaracaer inci Karaca 2004Chinese Medical Journal2004,17,2:3
14Noncontrast-enhanced MRI-based Noninvasive Score for Portal Hypertension(CHESS1802):An International Multicenter Study显示文摘Background and Aims:This study aimed to determine the performance of the non-invasive score using noncontrastenhanced MRI(CHESS-DIS score)for detecting portal hy-pertension in cirrhosis.Methods:In this international multicenter,diagnostic study(ClinicalTrials.gov,NCT03766880),patients with cirrhosis who had hepatic venous pressure gradient(HVPG)measurement and noncontrast-enhanced MRI were prospectively recruited from four university hospitals in China(n=4)and Turkey(n=1)between December 2018 and April 2019.A cohort of patients was retrospectively recruited from a university hospital in Italy between March 2015 and November 2017.After segmentation of the liver on fat-suppressed T1-weighted MRI maps,CHESS-DIS score was calculated automatically by an in-house developed code based on the quantification of liver surface nodularity.Results:A total of 149 patients were included,of which 124 were from four Chinese hospitals(training cohort)and 25 were from two international hospitals(validation cohort).A positive correlation between CHESS-DIS score and HVPG was found with the correlation coefficients of 0.36(p<0.0001)and 0.55(p<0.01)for the training and validation cohorts,respectively.The area under the receiver operating characteristic curve of CHESS-DIS score in detection of clinically significant portal hypertension(CSPH)was 0.81 and 0.9 in the training and validation cohorts,respectively.The intra-class correlation coefficients for assessing the inter-and intra-observer agreement were 0.846 and 0.841,respectively.Conclusions:A non-invasive score using noncontrast-enhanced MRI was developed and proved to be significantly correlated with invasive HVPG.Besides,this score could be used to detect CSPH in patients with cirrhosis.Yanna Liu Tianyu Tang NecatiÖrmeci Yifei Huang Jitao Wang Xiaoguo Li Zhiwei Li Weimin An Dengxiang Liu Chunqing Zhang Changchun Liu Jinqiang Liu Chuan Liu Guangchuan Wang Cristina Mosconi Alberta Cappelli Antonio Bruno Seray Akçalar EmrecanÇelebioğlu EvrenÜstüner Sadık Bilgiç Zeynep Ellik ÖzgünÖmer Asiller Lei Li Haijun Zhang Ning Kang Dan Xu Ruiling He Yan Wang Yang Bu Ye Gu Shenghong Ju Rita Golfieri Xiaolong Qi 2021Journal of Clinical and Translational Hepatology2021,9,6:3
15Magneto-rheological elastomer (MRE) based composite structures for micro-vibration control显示文摘Magneto-rheological elastomers (MREs) are used to construct composite structures for micro-vibration control of equipment under stochastic support-motion excitations.The dynamic behavior of MREs as a smart viscoelastic material is characterized by a complex modulus dependent on vibration frequency and controllable by external magnetic fields.Frequency-domain solution methods for stochastic micro-vibration response analysis of the MRE-based structural systems are developed to derive the system frequency-response function matrices and the expressions of the velocity response spectrum.With these equations, the root-mean-square (RMS) velocity responses in terms of the one-third octave frequency band spectrum can be calculated.Further, the optimization problem of the complex moduli of the MRE cores is defined by minimizing the velocity response spectra and the RMS velocity responses through altering the applied magnetic fields.Simulation results illustrate the influences of MRE parameters on the RMS velocity responses and the high response reduction capacities of the MRE-based structures.In addition, the developed frequency-domain analysis methods are applicable to sandwich beam structures with arbitrary cores characterized by complex shear moduli under stochastic excitations described by power spectral density functions, and are valid for a wide frequency range.YQ Ni ZG Ying ZH Chen 2010Earthquake Engineering and Engineering Vibration2010,9,3:2

18Effect of sodium tungstate on visual evoked potentials in diabetic rats显示文摘AIM: To evaluate the effect of sodium tungstate on visual evoked potentials(VEPs) in diabetic rats.· METHODS: Wistar rats were randomly divided into three groups as normal control, diabetic control and diabetic rats treated with sodium tungstate. Diabetes was induced by single intraperitoneal injection of streptozotocin(50 mg/kg). Sodium tungstate [40 mg/(kg·d)]was administered for 12 wk and then VEPs were recorded.Additionally, thiobarbituric acid reactive substance(TBARS) levels were measured in brain tissues.·RESULTS: The latencies of P1, N1, P2, N2 and P3 waves were significantly prolonged in diabetic rats compared with control group. Diabetes mellitus caused an increase in the lipid peroxidation process that was accompanied by changes in VEPs. However, prolonged latencies of VEPs for all components returned to control levels in sodium tungstate-treated group. The treatment of sodium tungstate significantly decreased brain TBARS levels and depleted the prolonged latencies of VEP components compared with diabetic control group.· CONCLUSION: Sodium tungstate shows protective effects on visual pathway in diabetic rats, and it can be worthy of further study for potential use.Mehmet Bulut Bariszgür Dnmez Nihai ztürk Gksum Basaranlar Ceren Kencebay Manas Narin Derin Semir zdemir 2016International Journal of Ophthalmology(English edition)2016,9,5:2

20Laser in situ keratomileusis in adult patients with anisometropic amblyopia显示文摘AIM: To evaluate the increase in corrected distance visual acuity (CDVA) after laser in situ keratomileusis (LASIK) in adults with anisometropic amblyopia. · METHODS: The medical records of consecutive patients diagnosed with anisometropic amblyopia at the time of refractive evaluation who underwent LASIK were retrospectively reviewed. Patients with at least a two-line difference of visual acuity (VA) between the eyes with a spherical refractive error difference of at least 3.00 diopters (D) or an astigmatic difference of at least 2.00D were included. Patients with any other possible reason for amblyopia other than anisometropia or those who had undergone previous amblyopia treatment were excluded. Amblyopic eyes with myopia or myopic astigmatism were considered as group 1, hypermetropia or hypermetropic astigmatism constituted group 2, and mixed astigmatism patients comprised group 3. Uncorrected distance visual acuity (UDVA), subjective manifest refraction, and CDVA were analyzed at 1 week and 1 month, 3, and 6 months. ·RESULTS: The study included 57 eyes of 57 patients. There were 33 eyes in group 1, 12 eyes in group 2, and 12 eyes in group 3. The preoperative mean values for spherical equivalent of subjective manifest refraction (SE) in groups 1, 2, and 3 were (-4.66±1.97)D, (4.40±1.00)D, and (0.15±1.05)D, respectively. Mean CDVA improved 0.1 log units (1 line LogMAR) at 6 months (P <0.05). Sixteen eyes (28%) exhibited an improvement in CDVA in week 1. Fourteen eyes (25% ) experienced two or more lines of CDVA improvement at month 6. There were no statistically significant differences among the groups in terms of CDVA (P >0.05). Moreover, age, the amount ofpreoperative refractive error, and the levels of preoperative corrected and UDVA had no effect on postoperative CDVA improvement (P >0.05). · CONCLUSION: Correction of refractive errors with LASIK produced significant CDVA improvement in adult patients with anisometropic amblyopia and no previous amblyopia treatment.Alper Agca Engin Bilge zgühan kkes Baz Ercüment Bozkurt Abdullah Ozkaya Dilek Yasa Ahmet Demirok 2013International Journal of Ophthalmology(English edition)2013,6,3:2
