| 1 | Autologous CD34^+ and CD133^+ stem cells transplantation in patients with end stage liver disease显示文摘AIM:To assess the utility of an autologous CD34 + and CD133 + stem cells infusion as a possible therapeutic modality in patients with end-stage liver diseases.METHODS:One hundred and forty patients with endstage liver diseases were randomized into two groups.Group 1,comprising 90 patients,received granulocyte colony stimulating factor for five days followed by autologous CD34 + and CD133 + stem cell infusion in the portal vein.Group 2,comprising 50 patients,received regular liver treatment only and served as a control group.RESULTS:Near normalization of liver enzymes and improvement in synthetic function were observed in 54.5% of the group 1 patients;13.6% of the patients showed stable states in the infused group.None of the patients in the control group showed improvement.No adverse effects were noted.CONCLUSION:Our data showed that a CD34 + and CD133 + stem cells infusion can be used as supportive treatment for end-stage liver disease with satisfactory tolerability. | Hosny Salama Abdel-Rahman N Zekri Abeer A Bahnassy Eman Medhat Hanan A Halim Ola S Ahmed Ghada Mohamed Sheren A Al Alim Ghada M Sherif | 2010 | World Journal of Gastroenterology2010，16，42： | 16 |
| 2 | 柴油乳化液喷雾闪急沸腾与微爆现象的激光阴影试验研究(英文)显示文摘在常压定容室内,应用ND:YAG激光阴影法、高分辨率CCD照相机和粒径分析软件,对不同含水量的柴油乳化液雾油滴的闪急沸腾与微爆现象以及油滴粒径分布进行了试验测量与变参数对比分析,探讨了在130℃温度条件下,乳化油含水量对乳化油喷雾液滴闪急沸腾和微爆的影响,揭示了微爆效应在喷雾雾化和液滴碎化中的作用机理。试验结果表明,包覆于油中的水相颗粒受热闪急沸腾所形成的高压蒸气团冲破无水边界层是导致油滴发生微爆和进一步破碎分裂的首要原因;微爆现象随乳化油含水量的增高而趋强;喷雾索特平均直径(SMD)的细化率随乳化油含水量和喷雾贯穿距的增加而增大,且乳化油含水量对喷雾SMD细化率的影响程度也随喷雾贯穿距的增加更加显著。 | MEDHAT Elkelawy 张煜盛 Alm El-Din Hagar 余敬周 El Zahaby A M El Shenawy E A Khalil A | 2009 | 内燃机学报2009，27，4： | 3 |

| 9 | Digestive system involvement and clinical outcomes among COVID-19 patients:A retrospective cohort study from Qatar显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)caused by the severe acute respiratory syndrome coronavirus 2 virus most commonly presents with respiratory symptoms.While gastrointestinal(GI)manifestations either at presentation or during hospitalization are also common,their impact on clinical outcomes is controversial.Some studies have described worse outcomes in COVID-19 patients with GI symptoms,while others have shown either no association or a protective effect.There is a need for consistent standards to describe GI symptoms in COVID-19 patients and to assess their effect on clinical outcomes,including mortality and disease severity.AIM To investigate the prevalence of GI symptoms in hospitalized COVID-19 patients and their correlation with disease severity and clinical outcomes.METHODS We retrospectively reviewed 601 consecutive adult COVID-19 patients requiring hospitalization between May 1-15,2020.GI symptoms were recorded at admission and during hospitalization.Demographic,clinical,laboratory,and treatment data were retrieved.Clinical outcomes included all-cause mortality,disease severity at presentation,need for intensive care unit(ICU)admission,development of acute respiratory distress syndrome,and need for mechanical ventilation.Multivariate logistic regression model was used to identify independent predictors of the adverse outcomes.RESULTS The prevalence of any GI symptom at admission was 27.1%and during hospitalization was 19.8%.The most common symptoms were nausea(98 patients),diarrhea(76 patients),vomiting(73 patients),and epigastric pain or discomfort(69 patients).There was no difference in the mortality between the two groups(6.21%vs 5.5%,P=0.7).Patients with GI symptoms were more likely to have severe disease at presentation(33.13%vs 22.5%,P<0.001)and prolonged hospital stay(15 d vs 14 d,P=0.04).There was no difference in other clinical outcomes,including ICU admission,development of acute respiratory distress syndrome,or need for mechanical ventilation.Drugs associated with the development of GI symptoms during hospitalization were ribavirin(diarrhea 26.37%P<0.001,anorexia 17.58%,P=0.02),hydroxychloroquine(vomiting 28.52%,P=0.009)and lopinavir/ritonavir(nausea 32.65%P=0.049,vomiting 31.47%P=0.004,and epigastric pain 12.65%P=0.048).In the multivariate regression analysis,age>65 years was associated with increased mortality risk[odds ratio(OR)7.53,confidence interval(CI):3.09-18.29,P<0.001],ICU admission(OR:1.79,CI:1.13-2.83,P=0.012),and need for mechanical ventilation(OR:1.89,CI:1.94-2.99,P=0.007).Hypertension was an independent risk factor for ICU admission(OR:1.82,CI:1.17-2.84,P=0.008)and need for mechanical ventilation(OR:1.66,CI:1.05-2.62,P=0.028).CONCLUSION Patients with GI symptoms are more likely to have severe disease at presentation;however,mortality and disease progression is not different between the two groups. | Muhammad Umair Khan Kamran Mushtaq Deema Hussam Alsoub Phool Iqbal Fateen Ata Hammad Shabir Chaudhry Fatima Iqbal Girisha Balaraju Muna A Al Maslamani Betsy Varughese Rajvir Singh Khalid Al Ejji Saad Al Kaabi Yasser Medhat Kamel Adeel Ajwad Butt | 2021 | World Journal of Gastroenterology2021，27，46： | 1 |
