| 1 | Reversibility of minimal hepatic encephalopathy following liver transplantation in Egyptian cirrhotic patients显示文摘AIM To evaluate the reversibility of minimal hepatic encephalopathy(MHE) following liver transplantation(LT) in Egyptian cirrhotic patients. METHODS This prospective study included twenty patients with biopsy-proven liver cirrhosis listed for LT and twenty ageand sex-matched healthy control subjects. All underwent neuro-psychiatric examination, laboratory investigations, radiological studies and psychometric tests including trail making test A(TMT A), TMT B, digit symbol test and serial dotting test. The psychometric hepatic encephalopathy score(PHES) was calculated for patients to diagnose MHE. Psychometric tests were repeated six months following LT in the cirrhotic patient group. RESULTS Before LT, psychometric tests showed highly significant deficits in cirrhotic patients in comparison to controls(P < 0.001). There was a statistically significant improvement in test values in the patient group after LT; however, their values were still significantly worse than those of the controls(P < 0.001). The PHES detected MHE in 16 patients(80%) before LT with a median value of -7 ± 3.5. The median PHES value was significantly improved following LT, reaching-4.5 ± 5(P < 0.001), and the number of patients with MHE decreased to 11(55%). The pre-transplant model for end-stage liver disease(MELD) score ≥ 15 was significantly related to the presence of post-transplant MHE(P = 0.005). More patients in whom reversal of MHE was observed had a pre-transplant MELD score < 15.CONCLUSION Reversal of MHE in cirrhotic patients could be achieved by LT, especially in those with a MELD score < 15. | Mahmoud A Osman Moataz M Sayed Khaled A Mansour Shereen A Saleh Wesam A Ibrahim Sara M Abdelhakam Mohamed Bahaa Wael A Yousry Hosam S Elbaz Reginia N Mikhail Azza M Hassan Ehab H Elsayed Dalia A Mahmoud | 2016 | World Journal of Hepatology2016，8，30： | 11 |
| 2 | 用于固态照明的Mn^4+离子光谱学显示文摘Mn^4+离子激活的荧光粉在固态照明领域作为红光发射的热点载体正日益受到关注。我们针对当前研究热度撰写了Mn^4+离子光谱学的回顾,并在回顾中聚焦了许多对红色荧光粉商业研制有价值的重要基础研究点。这些研究点涵盖了如何理解自由和晶场状态下Mn^4+离子的能级结构以及Mn^4+发射波长对基质的依赖关系。此外,我们就如何实验调控Mn^4+离子掺杂型荧光粉的发射波长和发光强度给出了许多实际可行的建议。更为重要的是,我们收集并讨论了100多种荧光粉基质中Mn^4+离子光谱学参数,对它们的理解将会为未来Mn^4+掺杂型红色荧光粉的实验开发奠定基础。 | BRIK Mikhail G 马崇庚 SRIVASTAVA Alok M PIASECKI Michal | 2020 | 发光学报2020，41，9： | 11 |
| 3 | Neurohumoral,cardiac and inflammatory markers in the evaluation of heart failure severity and progression显示文摘Heart failure is common in adult population,accounting for substantial morbidity and mortality worldwide.The main risk factors for heart failure are coronary artery disease,hypertension,obesity,diabetes mellitus,chronic pulmonary diseases,family history of cardiovascular diseases,cardiotoxic therapy.The main factor associated with poor outcome of these patients is constant progression of heart failure.In the current review we present evidence on the role of established and candidate neurohumoral biomarkers for heart failure progression management and diagnostics.A growing number of biomarkers have been proposed as potentially useful in heart failure patients,but not one of them still resembles the characteristics of the'ideal biomarker.'A single marker will hardly perform well for screening,diagnostic,prognostic,and therapeutic management purposes.Moreover,the pathophysiological and clinical significance of biomarkers may depend on the presentation,stage,and severity of the disease.The authors cover main classification of heart failure phenotypes,based on the measurement of left ventricular ejection fraction,including heart failure with preserved ejection fraction,heart failure with reduced ejection fraction,and the recently proposed category heart failure with mid-range ejection fraction.One could envisage specific sets of biomarker with different performances in heart failure progression with different left ventricular ejection fraction especially as concerns prediction of the future course of the disease and of left ventricular adverse/reverse remodeling.This article is intended to provide an overview of basic and additional mechanisms of heart failure progression will contribute to a more comprehensive knowledge of the disease pathogenesis. | Ekaterina A Polyakova Evgeny N Mikhaylov Dmitry L Sonin Yuri V Cheburkin Mikhail M Galagudza | 2021 | Journal of Geriatric Cardiology2021，18，1： | 4 |
| 4 | Effect of intra-abdominal pressure on respiratory function in patients undergoing ventral hernia repair显示文摘AIM: To determine the influence of intra-abdominal pressure(IAP) on respiratory function after surgical repair of ventral hernia and to compare two different methods of IAP measurement during the perioperative period. METHODS: Thirty adult patients after elective repair of ventral hernia were enrolled into this prospective study.IAP monitoring was performed via both a balloontipped nasogastric probe [intragastric pressure(IGP), Ci MON, Pulsion Medical Systems, Munich, Germany] and a urinary catheter [intrabladder pressure(IBP), Uno Meter Abdo-Pressure Kit, Uno Medical, Denmark] on five consecutive stages:(1) after tracheal intubation(AI);(2) after ventral hernia repair;(3) at the end of surgery;(4) during spontaneous breathing trial through the endotracheal tube; and(5) at 1 h after tracheal extubation. The patients were in the complete supine position during all study stages.RESULTS: The IAP(measured via both techniques) increased on average by 12% during surgery compared to AI(P < 0.02) and by 43% during spontaneous breathing through the endotracheal tube(P < 0.01). In parallel, the gradient between РаСО2 and Et CO2 [Р(а-et)CO2] rose significantly, reaching a maximum during the spontaneous breathing trial. The PаO2/Fi O2 decreased by 30% one hour after tracheal extubation(P = 0.02). The dynamic compliance of respiratory system reduced intraoperatively by 15%-20%(P < 0.025). At all stages, we observed a significant correlation between IGP and IBP(r = 0.65-0.81, P < 0.01) with a mean bias varying from-0.19 mm Hg(2SD 7.25 mm Hg) to-1.06 mm Hg(2SD 8.04 mm Hg) depending on the study stage. Taking all paired measurements together(n = 133), the median IGP was 8.0(5.5-11.0) mm Hg and the median IBP was 8.8(5.8-13.1) mm Hg. The overall r2 value( n = 30) was 0.76(P < 0.0001). Bland and Altman analysis showed an overall bias for the mean values per patient of 0.6 mm Hg(2SD 4.2 mm Hg) with percentage error of 45.6%. Looking at changes in IAP between the different study stages, we found an excellent concordance coefficient of 94.9% comparing IBP and IGP( n = 117).CONCLUSION: During ventral hernia repair, the IAP rise is accompanied by changes in Р(а-et)CO2 and PаO2/Fi O2-ratio. Estimation of IAP via IGP or IBP demonstrated excellent concordance. | Konstantin M Gaidukov Elena N Raibuzhis Ayyaz Hussain Alexey Y Teterin Alexey A Smetkin Vsevolod V Kuzkov Manu LNG Malbrain Mikhail Y Kirov | 2013 | World Journal of Critical Care Medicine2013，2，2： | 2 |
