| 1 | Clinical epidemiology and disease burden of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is defined as the presence of hepatic fat accumulation after the exclusion of other causes of hepatic steatosis, including other causes of liver disease, excessive alcohol consumption, and other conditions that may lead to hepatic steatosis. NAFLD encompasses a broad clinical spectrum ranging from nonalcoholic fatty liver to nonalcoholic steatohepatitis(NASH), advanced fibrosis, cirrhosis, and finally hepatocellular carcinoma(HCC). NAFLD is the most common liver disease in the world and NASH may soon become the most common indication for liver transplantation. Ongoing persistence of obesity with increasing rate of diabetes will increase the prevalence of NAFLD, and as this population ages, many will develop cirrhosis and end-stage liver disease. There has been a general increase in the prevalence of NAFLD, with Asia leading the rise, yet the United States is following closely behind with a rising prevalence from 15% in 2005 to 25% within 5 years. NAFLD is commonly associated with metabolic comorbidities, including obesity, type Ⅱ diabetes, dyslipidemia, and metabolic syndrome. Our understanding of the pathophysiology of NAFLD is constantly evolving. Based on NAFLD subtypes, it has the potential to progress into advanced fibrosis, end-stage liver disease and HCC. The increasing prevalence of NAFLD with advanced fibrosis, is concerning because patients appear toexperience higher liver-related and non-liver-related mortality than the general population. The increased morbidity and mortality, healthcare costs and declining health related quality of life associated with NAFLD makes it a formidable disease, and one that requires more in-depth analysis. | Brandon J Perumpail Muhammad Ali Khan Eric R Yoo George Cholankeril Donghee Kim Aijaz Ahmed | 2017 | World Journal of Gastroenterology2017,23,47: | 70 |
| 2 | Type Ⅰ and type Ⅱ Helicobacter pylori infection status and their impact on gastrin and pepsinogen level in a gastric cancer prevalent area显示文摘BACKGROUND Type I Helicobacter pylori(H.pylori)infection causes severe gastric inflammation and is a predisposing factor for gastric carcinogenesis.However,its infection status in stepwise gastric disease progression in this gastric cancer prevalent area has not been evaluated;it is also not known its impact on commonly used epidemiological gastric cancer risk markers such as gastrin-17(G-17)and pepsinogens(PGs)during clinical practice.AIM To explore the prevalence of type I and type II H.pylori infection status and their impact on G-17 and PG levels in clinical practice.METHODS Thirty-five hundred and seventy-two hospital admitted patients with upper gastrointestinal symptoms were examined,and 523 patients were enrolled in this study.H.pylori infection was confirmed by both 13C-urea breath test and serological assay.Patients were divided into non-atrophic gastritis(NAG),nonatrophic gastritis with erosion(NAGE),chronic atrophic gastritis(CAG),peptic ulcers(PU)and gastric cancer(GC)groups.Their serological G-17,PG I and PG II values and PG I/PG II ratio were also measured.RESULTS A total H.pylori infection rate of 3572 examined patients was 75.9%,the infection rate of 523 enrolled patients was 76.9%,among which type I H.pylori infection accounted for 72.4%(291/402)and type II was 27.6%;88.4%of GC patients were H.pylori positive,and 84.2%of them were type I infection,only 11.6%of GC patients were H.pylori negative.Infection rates of type I H.pylori in NAG,NAGE,CAG,PU and GC groups were 67.9%,62.7%,79.7%,77.6%and 84.2%,respectively.H.pylori infection resulted in significantly higher G-17 and PG II values and decreased PG I/PG II ratio.Both types of H.pylori induced higher G-17 level,but type I strain infection resulted in an increased PG II level and decreased PG I/PG II ratio in NAG,NAGE and CAG groups over uninfected controls.Overall PG I levels showed no difference among all disease groups and in the presence or absence of H.pylori;in stratified analysis,its level was increased in GC and PU patients in H.pylori and type I H.pylori-positive groups.CONCLUSION Type I H.pylori infection is the major form of infection in this geographic region,and a very low percentage(11.6%)of GC patients are not infected by H.pylori.Both types of H.pylori induce an increase in G-17 level,while type I H.pylori is the major strain that affects PG I and PG IIs level and PG I/PG II ratio in stepwise chronic gastric disease.The data provide insights into H.pylori infection status and indicate the necessity and urgency for bacteria eradication and disease prevention in clinical practice. | Lin Yuan Jun-Bo Zhao Ying-Lei Zhou Ya-Bin Qi Qiong-Ya Guo Hai-Hui Zhang Muhammad Noman Khan Ling Lan Chang-He Jia Yan-Rui Zhang Song-Ze Ding | 2020 | World Journal of Gastroenterology2020,26,25: | 29 |

| 4 | Biochemical and microbial properties of rhizospheres under maize/ peanut intercropping显示文摘Maize/peanut intercropping system shows the significant yield advantage. Soil microbes play major roles in soil nutrient cycling and were affected by intercropping plants. This experiment was carried out to evaluate the changing of rhizosphere microbial community composition, and the relationship between microbial community and soil enzymatic activities, soil nutrients in maize/peanut intercropping system under the following three treatments: maize(Zea mays L.) and peanut(Arachis hypogaea L.) were intercropped without any separation(NS), by half separation(HS) using a nylon net(50 μm) and complete separation(CS) by using a plastic sheet, respectively. The soil microbial communities were assessed by phospholipid fatty acid(PLFA). We found that soil available nutrients(available nitrogen(Avail N) and available phosphorus(Avail P)) and enzymatic activities(soil urase and phosphomonoesterase) in both crops were improved in NS and HS treatments as compared to CS. Both bacterial and fungal biomasses in both crops were increased in NS followed by HS. Furthermore, Gram-positive bacteria( G+) in maize soils were significant higher in NS and HS than CS, while the Gram-negative(G–) was significant higher in peanut soil. The ratio of normal saturated to monounsaturated PLFAs was significantly higher in rhizosphere of peanut under CS treatment than in any other treatments, which is an indicator of nutrient stress. Redundancy analysis and cluster analysis of PLFA showed rhizospheric microbial community of NS and HS of both plants tended to be consistent. The urase and Avail N were higher in NS and HS of both plants and positively correlated with bacteria, fungi(F) and total PLFAs, while negatively correlated with G+/G– and NS/MS. The findings suggest that belowground interactions in maize/peanut intercropping system play important roles in changing the soil microbial composition and the dominant microbial species, which was closely related with the improving of soil available nutrients(N and P) and enzymatic activities. | LI Qi-song | 2016 | Journal of Integrative Agriculture2016,15,1: | 24 |
| 5 | Crosstalk of liver immune cells and cell death mechanisms in different murine models of liver injury and its clinical relevance显示文摘BACKGROUND: Liver inflammation or hepatitis is a result of pluripotent interactions of cell death molecules, cytokines, chemokines and the resident immune cells collectively called as microenvironment. The interplay of these inflammatory mediators and switching of immune responses during hepatotoxic, viral, drug-induced and immune cell-mediated hepatitis decide the fate of liver pathology. The present review aimed to describe the mechanisms of liver injury, its relevance to human liver pathology and insights for the future therapeutic interventions.DATA SOURCES: The data of mouse hepatic models and relevant human liver diseases presented in this review are systematically collected from Pub Med, Science Direct and the Web of Science databases published in English. RESULTS: The hepatotoxic liver injury in mice induced by the metabolites of CCl4, acetaminophen or alcohol represent necrotic cell death with activation of cytochrome pathway, formation of reactive oxygen species(ROS) and mitochondrial damage. The Fas or TNF-α induced apoptotic liver injury was dependent on activation of caspases, release of cytochrome c and apoptosome formation. The Con A-hepatitis demonstrated the involvement of TRAIL-dependent necrotic/necroptotic cell death with activation of RIPK1/3. The α-Gal Cer-induced liver injury was mediated by TNF-α. The LPS-induced hepatitis involved TNF-α, Fas/Fas L, and perforin/granzyme cell death pathways. The MHV3 or Poly(I:C) induced liver injury was mediated by natural killer cells and TNF-α signaling. The necrotic ischemia-reperfusion liver injury was mediated byhypoxia, ROS, and pro-inflammatory cytokines; however, necroptotic cell death was found in partial hepatectomy. The crucial role of immune cells and cell death mediators in viral hepatitis(HBV, HCV), drug-induced liver injury, non-alcoholic fatty liver disease and alcoholic liver disease in human were discussed.CONCLUSIONS: The mouse animal models of hepatitis provide a parallel approach for the study of human liver pathology. Blocking or stimulating the pathways associated with liver cell death could unveil the novel therapeutic strategies in the management of liver diseases. | Hilal Ahmad Khan Muhammad Zishan Ahmad Junaid Ali Khan Muhammad Imran Arshad | 2017 | Hepatobiliary & Pancreatic Diseases International2017,16,3: | 24 |
| 6 | 不同雨强、坡度对秸秆覆盖保持水土效果的影响显示文摘利用室内人工模拟降雨试验,研究了4种设计雨强(33,54,94,125mm/h)、3种设计坡度(5°,10°,25°)在覆盖条件下对紫色土坡面初始产流时间、覆盖保水率和保沙率的影响。结果表明:覆盖条件下初始产流时间相比裸地均有一定的滞后效果,且其初始产流的滞后时间随坡度、雨强的增加而减少。当坡度增大至25°,雨强在94mm/h以上时,其滞后时间逐渐趋于稳定,在1.61~2.84min范围内波动。雨强是影响秸秆覆盖保持水土作用的重要因子,与覆盖保水率、保沙率均在0.01水平上呈显著负相关,且在不同坡度条件下均可以用抛物线进行很好的描述。不同坡度条件下,覆盖的保水率随雨强的增加逐渐下降至14.5%,而其保沙率则只下降至92.25%,相比覆盖的保水作用,其保沙作用更加明显。覆盖条件下,坡度对坡面产流及产沙的贡献率均大于50%,坡度对秸秆覆盖保持水土的作用影响很大。坡度对坡面侵蚀的贡献率在裸地和覆盖条件下均随雨强的增加而呈现减小的趋势,且在相同雨强下,坡度的贡献率在覆盖条件下均大于裸地,在大雨强下(94mm/h和125mm/h)差异明显。 | 车明轩 宫渊波 Muhammad Naeem Khan 陈兆利 曾倩 兰依依 | 2016 | 水土保持学报2016,30,2: | 17 |

| 8 | Antibiotic resistance and cagA gene correlation:A looming crisis of Helicobacter pylori显示文摘AIM:To determine antibiotic resistance of Helicobacter pylori(H.pylori) in Pakistan and its correlation with host and pathogen associated factors.METHODS:A total of 178 strains of H.pylori were isolated from gastric biopsies of dyspeptic patients.Susceptibility patterns against first and second-line antibiotics were determined and trends of resistance were analyzed in relation to the sampling period,gastric conditions and cagA gene carriage.The effect of cagA gene on the acquisition of resistance was investigated by mutant selection assay.RESULTS:The observations showed that monoresistant strains were prevalent with rates of 89% for metronidazole,36% for clarithromycin,37% for amoxicillin,18.5% for ofloxacin and 12% for tetracycline.Furthermore,clarithromycin resistance was on the rise from 2005 to 2008(32% vs 38%,P = 0.004) and it is significantly observed in non ulcerative dyspeptic patients compared to gastritis,gastric ulcer and duodenal ulcer cases(53% vs 20%,18% and 19%,P = 0.000).On the contrary,metronidazole and ofloxacin resistance were more common in gastritis and gastric ulcer cases.Distribution analysis and frequencies of resistant mutants in vitro correlated with the absence of cagA gene with metronidazole and ofloxacin resistance.CONCLUSION:The study confirms the alarming levels of antibiotic resistance associated with the degree of gastric inflammation and cagA gene carriage in H.pylori strains. | Adnan Khan Amber Farooqui Hamid Manzoor Syed Shakeel Akhtar Muhammad Saeed Quraishy Shahana Urooj Kazmi | 2012 | World Journal of Gastroenterology2012,18,18: | 15 |
| 9 | Cirrhosis and its complications:Evidence based treatment显示文摘Cirrhosis results from progressive fibrosis and is the final outcome of all chronic liver disease.It is among the ten leading causes of death in United States.Cirrhosis can result in portal hypertension and/or hepatic dysfunction.Both of these either alone or in combination can lead to many complications,including ascites,varices,hepatic encephalopathy,hepatocellular carcinoma,hepatopulmonary syndrome,and coagulation disorders.Cirrhosis and its complications not only impair quality of life but also decrease survival.Managing patients with cirrhosis can be a challenge and requires an organized and systematic approach.Increasing physicians’knowledge about prevention and treatment of these potential complications is important to improve patient outcomes.A literature search of the published data was performed to provide a comprehensive review regarding the management of cirrhosis and its complications. | Salman Nusrat Muhammad S Khan Javid Fazili Mohammad F Madhoun | 2014 | World Journal of Gastroenterology2014,20,18: | 14 |
| 10 | Thymosin alpha 1:A comprehensive review of the literature显示文摘Thymosin alpha 1 is a peptide naturally occurring in the thymus that has long been recognized for modifying,enhancing,and restoring immune function.Thymosin alpha 1 has been utilized in the treatment of immunocompromised states and malignancies,as an enhancer of vaccine response,and as a means of curbing morbidity and mortality in sepsis and numerous infections.Studies have postulated that thymosin alpha 1 could help improve the outcome in severely ill corona virus disease 2019 patients by repairing damage caused by overactivation of lymphocytic immunity and how thymosin alpha 1 could prevent the excessive activation of T cells.In this review,we discuss key literature on the background knowledge and current clinical uses of thymosin alpha 1.Considering the known biochemical properties including antibacterial and antiviral properties,timehonored applications,and the new promising findings regarding the use of thymosin,we believe that thymosin alpha 1 deserves further investigation into its antiviral properties and possible repurposing as a treatment against severe acute respiratory syndrome coronavirus-2. | Asimina Dominari Donald Hathaway III Krunal Pandav Wanessa Matos Sharmi Biswas Gowry Reddy Sindhu Thevuthasan Muhammad Adnan Khan Anoopa Mathew Sarabjot Singh Makkar Madiha Zaidi Michael Maher Mourad Fahem Renato Beas Valeria Castaneda Trissa Paul John Halpern Diana Baralt | 2020 | World Journal of Virology2020,9,5: | 11 |
| 11 | 25年长期定位不同施肥措施对关中塿土水力学性质的影响显示文摘土壤水力学性质和功能的变化是评价长期施肥是否维持土壤可持续健康发展的重要方面。该研究通过采取'国家黄土肥力与肥料效益监测基地'的表层原状土壤,分析测定了撂荒(LH)、休闲(XX)、不施肥(CK)、单施氮肥(N)、氮磷钾肥(NPK)和有机肥与氮磷钾肥配施(MNPK)6个处理的土壤水分特征曲线、饱和导水率和紧实度等指标,评价了长期定位施肥对土壤基本物理性质和水力学性质的影响。结果表明:1)与CK、N和NPK处理相比,MNPK处理显著提高了土壤有机碳、饱和导水率和孔隙度,而降低了土壤容重和紧实度(P<0.05)。2)不同施肥处理之间的土壤水分特征曲线表现出一定的差异,其土壤持水能力强弱为:XX9μm大孔隙范围内,其次是<0.2μm小孔隙范围,0.2~9μm之间的中孔隙分布较少。综上,MNPK有助于改善土壤结构,提高土壤持水性,降低土壤容重和紧实度,有助于作物生长和高产,是关中地区较为适宜的施肥措施。 | 兰志龙 Muhammad Numan Khan Tanveer Ali Sial 杨学云 赵英 张建国 | 2018 | 农业工程学报2018,34,24: | 10 |
| 12 | Assessment of sunflower germplasm for phytoremediation of lead-polluted soil and production of seed oil and seed meal for human and animal consumption显示文摘Phytoremediation is a valuable technology for mitigating soil contamination in agricultural lands,but phytoremediation without economic revenue is unfeasible for land owners and farmers.The use of crops with high biomass and bioenergy for phytoremediation is a unique strategy to derive supplementary benefits along with remediation activities.Sunflower(Helianthus annuus L.)is a high-biomass crop that can be used for the phytoremediation of polluted lands with additional advantages(biomass and oil).In this study,40 germplasms of sunflower were screened in field conditions for phytoremediation with the possibility for oil and meal production.The study was carried out to the physiological maturity stage.All studied germplasms mopped up substantial concentrations of Pb,with maximum amounts in shoot>root>seed respectively.The phytoextraction efficiency of the germplasm was assessed in terms of the Transfer factor(TF),Metal removal efficiency(MRE)and Metal extraction ratio(MER).Among all assessed criteria,GP.8585 was found to be most appropriate for restoring moderately Pb-contaminated soil accompanied with providing high biomass and high yield production.The Pb content in the oil of GP.8585 was below the Food safety standard of China,with 59.5% oleic acid and 32.1% linoleic acid.Moreover,amino acid analysis in meal illustrated significant differences among essential and nonessential amino acids.Glutamic acid was found in the highest percentage(22.4%),whereas cysteine in the lowest percentage(1.3%).Therefore,its efficient phytoextraction ability and good quality edible oil and meal production makes GP.8585 the most convenient sunflower germplasm for phytoremediation of moderately Pb-contaminated soil,with fringe benefits to farmers and landowners. | Afsheen Zehra Zulfiqar Ali Sahito Wenbin Tong Lin Tang Yasir Hamid Muhammad Bilal Khan Zarina Ali Beena Naqui Xiaoe Yang | 2020 | Journal of Environmental Sciences2020,32,1: | 10 |
| 13 | Update on the applications and limitations of alpha-fetoprotein for hepatocellular carcinoma显示文摘Alpha-fetoprotein(AFP)is an oncofetal glycoprotein that has been used as a tumor marker for hepatocellular carcinoma(HCC)in combination with ultrasound and other imaging modalities.Its utility is limited because of both low sensitivity and specificity,and discrepancies among the different methods of measurements.Moreover,its accuracy varies according to patient characteristics and the AFP cut-off values used.Combination of AFP with novel biomarkers such as AFP-L3,Golgi specific membrane protein(GP73)and des-gamma-carboxyprothrombin significantly improved its accuracy in detecting HCC.Increased AFP level could also signify severity of hepatic destruction and subsequent regeneration and is commonly observed in patients with acute and chronic liver conditions and cirrhosis.Hereditary and other non-hepatic disorders can also cause AFP elevation. | Hira Hanif Mukarram Jamat Ali Ammu T Susheela Iman Waheed Khan Maria Alejandra Luna-Cuadros Muzammil Muhammad Khan Daryl Tan-Yeung Lau | 2022 | World Journal of Gastroenterology2022,28,2: | 9 |

| 15 | Adsorptive removal of phosphate by the bimetallic hydroxide nanocomposites embedded in pomegranate peel显示文摘This study aimed to fabricate new and effective material for the efficiency of phosphate adsorption.Two types of adsorbent materials,the zirconium hydroxides embedded in pomegranate peel(Zr/Peel)and zirconium-lanthanum hydroxides embedded in pomegranate peel(Zr-La/Peel)were developed.Scanning electronic microscopy(SEM),x-ray photoelectron spectroscopy(XPS)and x-ray diffraction(XRD)were evaluated to give insight into the physicochemical properties of these adsorbents.Zr-La/Peel exceeded the adsorption efficiency of Zr/Peel adsorbents in batch adsorption experiments at the same pH level.The peel as a host can strive to have a strong'shielding effect'to increase the steadiness of the entrenched Zr and La elements.La and Zr are hydroxide metals that emit many hydrogen ions during the hydrolysis reaction,which contribute to protonation and electrostatic attraction.The highest adsorption capacity of La-Zr/Peel for phosphate was calculated to be40.21 mg/g,and pseudo second-order equation is very well fitted for kinetic adsorption.Phosphate adsorption efficiency was reduced by an increase of pH.With the background of coexisting Cl-,little effect on adsorption efficiency was observed,while adsorption capacities were reduced by almost 20-30%with the coexistence of SO42-,NO3-and humic acid(HA). | Muhammad Akram Xing Xu Baoyu Gao Qinyan Yue Shang Yanan Rizwan Khan Muhammad Ali Inam | 2020 | Journal of Environmental Sciences2020,32,5: | 8 |

| 17 | Correlation of transient elastography with hepatic venous pressure gradient in patients with cirrhotic portal hypertension: A study of 326 patients from India显示文摘AIM To study the diagnostic accuracy of transient elastography(TE) for detecting clinically significant portal hypertension(CSPH) in Indian patients with cirrhotic portal hypertension.METHODS This retrospective study was conducted at the Institute of Liver, Gastroenterology, and Panceatico-Biliary Sciences, Sir Ganga Ram Hospital, New Delhi, on consecutive patients with cirrhosis greater than 15 years of age who underwent hepatic venous pressure gradient(HVPG) and TE from July 2011 to May 2016. Correlation between HVPG and TE was analyzed using the Spearman's correlation test. Receiver operating characteristic ( ROC) curves were prepared for determining the utility of TE in predicting various stages of portal hypertension. The best cut-off value of TE forthe diagnosis of CSPH was obtained using the Youden index.RESULTS The study included 326 patients [median age 52(range 16-90) years; 81% males]. The most common etiology of cirrhosis was cryptogenic(45%) followed by alcohol(34%). The median HVPG was 16.0(range 1.5 to 30.5) mm Hg. Eighty-five percent of patients had CSPH. A significant positive correlation was noted between TE and HVPG(rho 0.361, P < 0.001). The area under ROC curve for TE in predicting CSPH was 0.740(95%CI: 0.662-0.818)(P < 0.01). A cut-off value of TE of 21.6 k Pa best predicted CSPH with a positive predictive value(PPV) of 93%.CONCLUSION TE has a fair positive correlation with HVPG; thus, TE can be used as a non-invasive modality to assess the degree of portal hypertension. A cut-off TE value of 21.6 k Pa identifies CSPH with a PPV of 93%. | Ashish Kumar Noor Muhammad Khan Shrihari Anil Anikhindi Praveen Sharma Naresh Bansal Vikas Singla Anil Arora | 2017 | World Journal of Gastroenterology2017,23,4: | 8 |

| 19 | Vegetation-environment relationships in the forests of Chitral district Hindukush range of Pakistan显示文摘We investigated the composition of plant communities to quantify their relationships with environmental parameters in the Chitral Hindukush range of Pakistan. We sampled tree vegetation using the Point Centered Quarter (PCQ) method while understory vegetation was sampled in 1.5-m circular quadrats. Cedrus deodara is the national symbol of Pakistan and was dominant in the sampled communities. Because environmental variables determine vegetation types, we analyzed and evaluated edaphic and topographic factors. DCA-Ordination showed the major gradient as an amalgam of elevation (p<0.05) and slope (p<0.01) as the topographic factors correlated with species distribution. Soil variables were the factors of environmental significance along DCA axes. However, among these factors, Mg2+ , K + and N2+ contributed not more than 0.054% 0.20% and 0.073%, respectively, to variation along the first ordination axis. We conclude that the principal reason for weak or no correlation with many edaphic variables was the anthropogenic disturbance of vegetation. The understory vegetation was composed of perennial herbs in most communities and was most dense under the tree canopy. The understory vegetation strongly regulates tree seedling growth and regeneration patterns. We recommend further study of the understory vegetation using permanent plots to aid development of forest regeneration strategies. | Nasrullah Khan Syed Shahid Shaukat Moinuddin Ahmed Muhammad Faheem Siddiqui | 2013 | Journal of Forestry Research2013,24,2: | 8 |
| 20 | Recognition of motor imagery tasks for BCI using CSP and chaotic PSO twin SVM显示文摘Accurate modeling and recognition of the brain activity patterns for reliable communication and interaction are still a challenging task for the motor imagery(MI) brain-computer interface(BCI) system. In this paper, we propose a common spatial pattern(CSP) and chaotic particle swarm optimization(CPSO) twin support vector machine(TWSVM) scheme for classification of MI electroencephalography(EEG). The self-adaptive artifact removal and CSP were used to obtain the most distinguishable features. To improve the recognition results, CPSO was employed to tune the hyper-parameters of the TWSVM classifier. The usefulness of the proposed method was evaluated using the BCI competition IV-IIa dataset. The experimental results showed that the mean recognition accuracy of our proposed method was increased by 5.35%, 4.33%, 0.78%, 1.45%, and 9.26% compared with the CPSO support vector machine(SVM), particle swarm optimization(PSO) TWSVM, linear discriminant analysis(LDA), back propagation(BP) and probabilistic neural network(PNN), respectively. Furthermore, it achieved a faster or comparable central processing unit(CPU) running time over the traditional SVM methods. | Li Duan Zhang Hongxin Muhammad Saad Khan Mi Fang | 2017 | The Journal of China Universities of Posts and Telecommunications2017,24,3: | 7 |
