| 1 | Prevalence of minimal hepatic encephalopathy and quality of life evaluations in hospitalized cirrhotic patients in China显示文摘AIM:To investigate the prevalence of minimal hepatic encephalopathy(MHE)and to assess corresponding health-related quality of life(HRQoL)in hospitalized cirrhotic patients in China.METHODS:This multi-center cross-sectional study included 16 teaching hospitals,which were members of 'Hepatobiliary Cooperation Group,Society of Gastroenterology,Chinese Medical Association',from different areas of China carried out between June and October in 2011.All the eligible hospitalized cirrhotic patients(n = 538)were required to complete triplicate number connection tests combined with one digit symbol test for diagnosing MHE.Patients' clinical examination data were complemented by a modified questionnaire assessing HRQoL.Written informed consent was obtained from each patient.RESULTS:Male was predominant(68.6%)in 519 patients who met the criteria of the study,with a mean age of 49.17 ± 11.02 years.The most common cause of liver cirrhosis was chronic hepatitis B(55.9%).The prevalence of MHE was 39.9% and varied by ChildPugh-Classification score(CPC-A:24.8%,CPC-B:39.4% and CPC-C:56.1%,P < 0.01).MHE(P < 0.01)and higher CPC scores(P < 0.01)were associated with a high HRQoL scores(reflecting poorer quality of life).The prevalence of MHE was proportionate to CPC(P = 0.01)and high quality of life scores(P = 0.01).CONCLUSION:Hospitalized cirrhotic patients have a high prevalence of MHE that is proportionate to the degree of liver function and HRQoL impairment. | Ji-Yao Wang Ning-Ping Zhang Bao-Rong Chi Yu-Qing Mi Li-Na Meng Ying-Di Liu Jiang-Bin Wang Hai-Xing Jiang Jin-Hui Yang Yun Xu Xiao Li Jian-Ming Xu Guo Zhang Xin-Min Zhou Yu-Zheng Zhuge De-An Tian Jin Ye Yu-Lan Liu | 2013 | World Journal of Gastroenterology2013,19,30: | 64 |
| 2 | Oral health status in Sichuan Province: findings from the oral health survey of Sichuan, 2015–2016显示文摘To investigate oral health status in the residents of Sichuan Province, southwest China, a cross-sectional study was performed using the latest Oral Health Survey Basic Methods recommended by the World Health Organization. A multistage stratified random cluster-sampling method was used to enroll participants from the following three groups: children aged 3–5 years,adolescents aged 12 years, and people aged 65–74 years. In these three groups, the mean numbers of teeth that were affected by caries were 3.28, 0.86 and 5.13, respectively, resulting in a prevalence of 63.47%, 37.20% and 83.20%, respectively.Relative to the high rate of decayed teeth, the prevalence of fillings was very low in all age groups(0.97%, 7.24% and 5.43%,respectively). In the 12-year-old adolescent group, only 3.61% had good pit and fissure sealing. In addition, the rate of dental fluorosis was 24.80%, and the Community Fluorosis Index value was 0.39. In the elder group, the community periodontal index was2.92. The prevalence in the elderly of having lost at least one tooth was 75.54%. Additionally, 4.44% of these participants were edentulous. The incidence of dental prosthesis was 51.75%, the proportion with a removable partial denture, a fixed denture, full dentures, dental implants and an informal fixed bridge was 21.59%, 11.45%, 4.64%, 0 and 16.67%, respectively. In this study,8.2% of the elderly participants were affected by different types of oral mucosal lesions. Among such lesions, recurrent aphthous ulcers were most prevalent(2.69%) and oral lichen planuses were second(1.6%). The conclusion presented in this survey is that oral diseases, especially dental caries and periodontal disease, are frequent and common in Sichuan province, China. Moreover, the treatment rate is very low, and primary prevention and treatment options are therefore urgently needed in this population. | Wei Yin Ying-Ming Yang Hong Chen Xue Li Zhuo Wang Li Cheng Qiu-Dan Yin Hong-Zhi Fang Wei Fei Fang-Lin Mi Min-Hai Nie Tao Hu Xue-Dong Zhou | 2017 | International Journal of Oral Science2017,9,1: | 30 |
| 3 | Causes associated with recurrent choledocholithiasis following therapeutic endoscopic retrograde cholangiopancreatography: A large sample sized retrospective study显示文摘BACKGROUND Recurrence of primary choledocholithiasis commonly occurs after complete removal of stones by therapeutic endoscopic retrograde cholangiopancreatography(ERCP). The potential causes of the recurrence of choledocholithiasis after ERCP are unclear.AIM To analyze the potential causes of the recurrence of choledocholithiasis after ERCP.METHODS The ERCP database of our medical center for the period between January 2007 and January 2016 was retrospectively reviewed, and information regarding eligible patients who had choledocholithiasis recurrence was collected. A 1:1 case-control study was performed for this investigation. Data including general characteristics of the patients, past medical history, ERCP-related factors,common bile duct(CBD)-related factors, laboratory indicators, and treatment was analyzed by univariate and multivariate logistic regression analysis and KaplanMeier analysisly.RESULTS First recurrence of choledocholithiasis occurred in 477 patients; among these patients, the second and several instance(≥ 3 times) recurrence rates were 19.5%and 44.07%, respectively. The average time to first choledocholithiasis recurrence was 21.65 mo. A total of 477 patients who did not have recurrence were selected as a control group. Multivariate logistic regression analysis showed that age > 65 years(odds ratio [OR] = 1.556; P = 0.018), combined history of choledocholithotomy(OR = 2.458; P < 0.01), endoscopic papillary balloon dilation(OR = 5.679; P = 0.000), endoscopic sphincterotomy(OR = 3.463; P = 0.000), CBD stent implantation(OR = 5.780; P = 0.000), multiple ERCP procedures(≥2; OR =2.75; P = 0.000), stones in the intrahepatic bile duct(OR = 2.308; P = 0.000),periampullary diverticula(OR = 1.627; P < 0.01), choledocholithiasis diameter ≥10 mm(OR = 1.599; P < 0.01), bile duct-duodenal fistula(OR = 2.69; P < 0.05),combined biliary tract infections(OR = 1.057; P < 0.01), and no preoperative antibiotic use(OR = 0.528; P < 0.01) were independent risk factors for the recurrence of choledocholithiasis after ERCP.CONCLUSION Patient age greater than 65 years is an independent risk factor for the development of recurrent choledocholithiasis following ERCP, as is history of biliary surgeries, measures during ERCP, and prevention of postoperative complications. | Feng Deng Mi Zhou Ping-Ping Liu Jun-Bo Hong Guo-Hua Li Xiao-Jiang Zhou You-Xiang Chen | 2019 | World Journal of Clinical Cases2019,7,9: | 26 |
| 4 | Portosplenomesenteric vein thrombosis in patients with early-stage severe acute pancreatitis显示文摘AIM To investigate the incidence and risk factors of portosplenomesenteric vein thrombosis(PSMVT) in the early stage of severe acute pancreatitis(SAP).METHODS Patients with SAP in a tertiary care setting from January 2014 to December 2016 were retrospectively reviewed. All contrast-enhanced computed tomography(CT) studies were reassessed and reviewed. Clinical outcome measures were compared between SAP patients with and without PSMVT in the early stage of the disease. Univariate and multivariate logistic regression analyses were sequentially performed to assess potential risk factors for the development of PSMVT in SAP patients. A receiver operating characteristic(ROC) curve was generated for the qualifying independent risk factors.RESULTS Twenty-five of the one hundred and forty(17.86%) SAP patients developed PSMVT 6.19 ± 2.43 d after acute pancreatitis(AP) onset. PSMVT was confirmed by contrast-enhanced CT. Multivariate stepwise logistic regression analyses showed that Balthazar's CT severity index(CTSI) scores [odds ratio(OR): 2.742; 95% confidence interval(CI): 1.664-4.519; P = 0.000], hypoalbuminemia(serum albumin level < 25 g/L)(OR: 32.573; 95%CI: 2.711-391.353; P = 0.006) and gastrointestinal wall thickening(OR: 4.367, 95%CI: 1.218-15.658; P = 0.024) were independent risk factors for PSMVT developed in patients with SAP. The area under the ROC curve for Balthazar's CTSI scores was 0.777(P = 0.000), the sensitivity was 52%, and the specificity was 93% at a cut-off value of 5.5.CONCLUSION High Balthazar's CTSI scores, hypoalbuminemia and gastrointestinal wall thickening are independent risk factors for PSMVT developed in the early stage of SAP. | Ling Ding Feng Deng Chen Yu Wen-Hua He Liang Xia Mi Zhou Xin Huang Yu-Peng Lei Xiao-Jiang Zhou Yin Zhu Nong-Hua Lu | 2018 | World Journal of Gastroenterology2018,24,35: | 20 |

| 9 | Roasting and leaching behaviors of vanadium and chromium in calcification roasting–acid leaching of high-chromium vanadium slag显示文摘Calcification roasting–acid leaching of high-chromium vanadium slag(HCVS)was conducted to elucidate the roasting and leaching behaviors of vanadium and chromium.The effects of the purity of Ca O,molar ratio between Ca O and V_2O_5(n(Ca O)/n(V_2O_5)),roasting temperature,holding time,and the heating rate used in the oxidation–calcification processes were investigated.The roasting process and mechanism were analyzed by X-ray diffraction(XRD),scanning electron microscopy(SEM),and thermogravimetry–differential scanning calorimetry(TG–DSC).The results show that most of vanadium reacted with Ca O to generate calcium vanadates and transferred into the leaching liquid,whereas almost all of the chromium remained in the leaching residue in the form of(Fe_(0.6)Cr_(0.4))_2O_3.Variation trends of the vanadium and chromium leaching ratios were always opposite because of the competitive reactions of oxidation and calcification between vanadium and chromium with Ca O.Moreover,Ca O was more likely to combine with vanadium,as further confirmed by thermodynamic analysis.When the HCVS with Ca O added in an n(Ca O)/n(V_2O_5)ratio of 0.5 was roasted in an air atmosphere at a heating rate of 10°C/min from room temperature to 950°C and maintained at this temperature for 60 min,the leaching ratios of vanadium and chromium reached91.14%and 0.49%,respectively;thus,efficient extraction of vanadium from HCVS was achieved and the leaching residue could be used as a new raw material for the extraction of chromium.Furthermore,the oxidation and calcification reactions of the spinel phases occurred at 592and 630°C for n(Ca O)/n(V_2O_5)ratios of 0.5 and 5,respectively. | Jing Wen Tao Jiang Mi Zhou Hui-yang Gao Jia-yi Liu Xiang-xin Xue | 2018 | International Journal of Minerals,Metallurgy and Materials2018,25,5: | 14 |
| 10 | The role of maize root size in phosphorus uptake and productivity of maize/faba bean and maize/wheat intercropping systems显示文摘Interspecific root/rhizosphere interactions affect phosphorus (P) uptake and the productivity of maize/faba bean and maize/wheat intercropping systems. The aim of these experiments was to determine whether manipulation of maize root growth could improve the productivity of the two intercropping systems. Two near isogenic maize hybrids (the larger-rooted T149 and smaller-rooted T222) were intercropped with faba bean and wheat, under conditions of high- and low-P availability. The larger-rooted T149 showed greater competitive ability than the smaller-rooted T222 in both maize/faba bean and maize/wheat intercropping systems. The higher competitive ability of T149 improved the productivity of the maize/faba bean intercropping system in P-sufficient conditions. In maize/wheat intercropping systems, root growth, shoot biomass, and P uptake of maize were inhibited by wheat, regardless of the P-supply. Compared with T222, the larger-rooted T149 suffered less in the intercropping systems. The total biomass of the maize/wheat intercropping system was higher for wheat/T149 than for wheat/T222 under low-P conditions. These data suggested that genetic improvement of maize root size could enhance maize growth and its ability to compete for P resources in maize/faba bean and maize/wheat intercropping systems. In addition, depending on the P availability, larger maize roots could increase the productivity of intercropping systems. | ZHANG YiKai CHEN FanJun LI Long CHEN YanHua LIU BingRan ZHOU YuLing YUAN LiXing ZHANG FuSuo MI GuoHua | 2012 | Science China(Life Sciences)2012,55,11: | 13 |

| 14 | Blood perfusion of the contralateral testis evaluated with contrast-enhanced ultrasound in rabbits with unilateral testicular torsion显示文摘The changes of blood perfusion of contralateral testis after unilateral testicular torsion remain controversial.In this study,28 New Zealand white male rabbits were randomly divided into five groups.Group A(n=8),the control group,underwent a sham operation on the unilateral testis without inducing testicular torsion.In groups B,C,and D(n=5 each),unilateral testicular torsion was induced,and,after 3,6 or 24 h,respectively,detorsion was performed.In group E(n=5),permanent unilateral testicular torsion was applied.Contrast-enhanced ultrasound was used to observe the blood perfusion of the contralateral testis at the following stages:pre-torsion(preopration),immediately post-torsion(postopration),pre-detorsion,immediately post-detorsion,and late-stage post-detorsion(6-12 h post-detorsion in groups B-D)or at a similar time point(15-21 h post-torsion in group E).Time-intensity curves were generated,and the following parameters were derived and analyzed:arrival time,time to peak intensity,peak intensity,and half-time of the descending peak intensity.The analysis revealed that blood perfusion of the contralateral testis increased immediately after testicular torsion on the opposite side(P<0.05),which increased with prolonged testicular torsion of the other testis.This research demonstrated that contrast-enhanced ultrasound was valuable in evaluating blood perfusion of the contralateral testis after unilateral testicular torsion. | Lin Chen Wei-Wei Zhan Zhou-Jun Shen Wen-Bin Rui Chen Lv Man Chen Jian-Qiao Zhou Ping Zhou Mi Zhou Ying Zhu | 2009 | Asian Journal of Andrology2009,11,2: | 10 |
| 15 | Loss of microRNAs in thymus perturbs invariant NKT cell development and function显示文摘microRNAs(miRNAs)are small noncoding RNAs that mediate RNA interference to suppress protein expression at the translational level.Accumulated evidence indicates that miRNAs play critical roles in various biological processes and disease development,including autoimmune diseases.Invariant natural killer T(iNKT)cells are an unusual CD1d-restricted subset of thymus-derived T cells that are potent regulators of diverse immune responses.Our previous studies with the mouse model of bone marrow-specific Dicer deletion suggest the involvement of Dicer-dependent miRNAs in the development and function of iNKT cells.In the present study,to further dissect the functional levels of Dicer-dependent miRNAs in regulating iNKT cell development,we generated a mouse model with the Dicer deletion in the thymus.Our data indicate that lack of miRNAs following the deletion of Dicer in the thymus severely interrupted the development and maturation of iNKT cells in the thymus and significantly decreased the number of iNKT cells in the peripheral immune organs.miRNA-deficient peripheral iNKT cells display profound defects in activation and cytokine production upon a-galactosylceramide(a-GalCer)stimulation.Our results demonstrate a critical role of the miRNA-dependent pathway in the thymus in the regulation of iNKT cell development and function. | Kook-Heon Seo Li Zhou Dongmei Meng Jianrui Xu Zhong Dong Qing-Sheng Mi | 2010 | Cellular & Molecular Immunology2010,7,6: | 9 |
| 16 | Numerical and experimental research on different inlet configurations of high speed centrifugal compressor显示文摘Three different inlet configurations,including a original straight pipe and two bend pipes with different axial length,for a high speed low mass flow centrifugal compressor were modeled with whole blade passages and simulated unsteadily by 3D viscous Navier-Stokes equations.The performance disparities of compressor stage were tested and verified by experiments in which dynamic pressure data acquisition of internal flow field was performed.As the result shows,the choke point decreases to lower mass flow rate due to the distortion caused by bend-pipe inlet and is aggravated as the rotation speed increases.The distortion effect spreads circumferentially in impeller and makes the flow structure varied.The longer axial distance bent inlet leads to larger radial distortion and heavy blockage at mid-span under large mass flow mainly causes compressor choke margin nar-rowed.Bend pipe distortion brings an impact up to diffuser on unsteady pressure pulsation caused by blades sweep and the impact appears more powerful when it is closer to volute tongue. | LI Du YANG Ce ZHOU Mi ZHU ZhiFu WANG Hang | 2012 | Science China(Technological Sciences)2012,55,1: | 9 |
| 17 | Role of the nucleus tractus solitarii in the protection of pre-moxibustion on gastric mucosal lesions显示文摘Previous studies have shown that somatic sensation by acupuncture and visceral nociceptive stimulation can converge in the nucleus tractus solitarii where neurons integrate signals impacting on the function of organs. To explore the role of the nucleus tractus solitarii in the protective mechanism of pre-moxibustion on gastric mucosa, nucleus tractus solitarii were damaged in rats and pre-moxibustion treatment at the Zusanli(ST36) point followed. The gastric mucosa was then damaged by the anhydrous ethanol lavage method. Morphological observations, enzyme linked immunosorbent assays, and western immunoblot analyses showed that gastric mucosa surface lesion and the infiltration of inflammatory cells were significantly ameliorated after pre-moxibustion treatment. Furthermore, the gastric mucosal damage index and somatostatin level were reduced, and epidermal growth factor content in the gastric mucosa and heat-shock protein-70 expression were increased. These results were reversed by damage to the nucleus tractus solitarii. These findings suggest that moxibustion pretreatment at the Zusanli point is protective against acute gastric mucosa injury, and nucleus tractus solitarii damage inhibits these responses. Therefore, the nucleus tractus solitarii may be an important area for regulating the signal transduction of the protective effect of pre-moxibustion on gastric mucosa. | Liang Peng Mi Liu Xiaorong Chang Zhou Yang Shouxiang Yi Jie Yan Yan Peng | 2014 | Neural Regeneration Research2014,9,2: | 9 |
| 18 | Endophytes and their role in phytoremediation显示文摘Many endophytes have been found to be resistant to heavy metals and/or capable of degrading organic contaminants,and endophyte-assisted phytoremediation has been documented as a promising technology for in situ remediation of contaminated soils.During the phytoremediation of heavy metals,the heavy-metal-resistant endophytes can enhance plant growth,decrease metal phytotoxicity,and affect metal translocation and accumulation in plants.For the phytoremediation of organic contaminants,endophytes can produce various enzymes to degrade organic contaminants and reduce both the phytotoxicity and evapotranspiration of volatile contaminants.This paper reviews the diversity of contaminant-resistant/degrading endophytes and their role in phytoremediation and discusses some issues that have been raised surrounding this area of research. | Hai-Yan Li Da-Qiao Wei Mi Shen Zuo-Ping Zhou | 2012 | Fungal Diversity2012,,3: | 8 |
