| 1 | 健康老年妇女近段股骨骨密度和结构的定量CT研究显示文摘目的采用定量CT(QCT)和双能X线吸收测量(DXA)仪对健康老年妇女近段股骨骨密度(BMD)和骨结构进行研究,并对2种测量方法的结果进行比较。方法对66名65岁以上健康妇女左侧髋关节进行DXA测量,计算出股骨颈和粗隆区BMD;对其双侧近段股骨进行QCT测量,计算出股骨颈、粗隆区和整体股骨ROI的皮质骨、松质骨和总体骨的BMD和体积;并将QCT三维图像模拟DXA的平面投影计算出模拟DXA股骨颈BMD和模拟DXA股骨粗隆区BMD。对所获数据进行配对t检验或非参数秩和检验,并用Pearson法分析DXA和QCT相对应ROI的相关性。结果用QCT可以对股骨近段不同ROI(股骨颈、粗隆区和整体股骨区)及不同骨成分(皮质骨、松质骨和总体骨)的BMD及体积等参数进行精确的定量分析。除右侧股骨颈皮质骨BMD[(0.52±0.04)g/cm^3]、股骨粗隆区皮质骨BMD[(0.49±0.03)g/cm^3]、股骨粗隆区综合骨BMD[(0.22±0.04)g/cm^3]大于左侧相应参数[分别为[(0.51±0.04)、(0.48±0.03)、(0.21±0.04)g/cm^3],差异均有统计学意义(P值均〈0.05),但差别均〈3.3%;而模拟DXA股骨颈BMD、模拟DXA股骨粗隆区BMD、股骨颈皮质骨体积、股骨颈松质骨BMD、股骨颈松质骨体积、股骨颈综合骨BMD、股骨颈综合骨体积、股骨粗隆区皮质骨体积、股骨粗隆区松质骨BMD、股骨粗隆区松质骨体积、股骨粗隆区综合骨体积左侧参数分别为(0.52±0.10)g/cm^2、(0.78±0.13)g/cm^2、5.80cm^3、(0.06±0.03)g/cm^3、(5.19±1.40)cm^3、(0.25±0.04)g/cm^3、15.66cm^3、(21.74±3.43)cm^3、(0.08±0.03)g/cm^3、(34.27±6.09)cm^3、(76.12±11.11)cm^3,右侧分别为(0.52±0.10)g/cm^2、(0.78±0.13)g/cm^2、6.01cm^3、(0.06±0.02)g/cm^3、(5.17±1.27)cm^3、(0.25±0.04)g/cm^3、15.62cm^3、(22.12±3.60)cm^3、(0.09±0.03)g/cm^3、(34.17±5.94)cm^3、(76.53±10.71)cm^3,差异均无统计学意义(P值均〉0.05)。左右两侧近段股骨QcT各相对应参数之间的r值范围在0.656~0.955,均具有相关性(P〈0.05)。QcT模拟DXA股骨颈和粗隆区BMD与真正DXA测量的相应值之间r值分别为0.685和0.855,具有相关性(P〈0.05)。结论利用QCT技术可以对老年妇女近段股骨不同区域和不同成分的BMD和结构进行精确定量分析,QCT是骨质疏松研究中非常有用的测量技术。 | 程晓光 Li Jing 刘霞 王予生 李谨 屈辉 H Genant T Lang | 2009 | 中华放射学杂志2009，43，2： | 8 |
| 2 | Hematological disorders and pulmonary hypertension显示文摘Pulmonary hypertension(PH),a serious disorder with a high morbidity and mortality rate,is known to occur in a number of unrelated systemic diseases.Several hematological disorders such as sickle cell disease,thalassemia and myeloproliferative diseases develop PH which worsens the prognosis.Associated oxidant injury and vascular inflammation cause endothelial damage and dysfunction.Pulmonary vascular endothelial damage/dysfunction is an early event in PH resulting in the loss of vascular reactivity,activation of proliferative and antiapoptotic pathways leading to vascular remodeling,elevated pulmonary artery pressure,right ventricular hypertrophy and premature death.Hemolysis observed in hematological disorders leads to free hemoglobin which rapidly scavenges nitric oxide(NO),limiting its bioavailability,and leading to endothelial dysfunction.In addition,hemolysis releases arginase into the circulation which converts L-arginine to ornithine,thus bypassing NO production.Furthermore,treatments for hematological disorders such as immunosuppressive therapy,splenectomy,bone marrow transplantation,and radiation have been shown to contribute to the development of PH.Recent studies have shown deregulated iron homeostasis in patients with cardiopulmonary diseases including pulmonary arterial hypertension(PAH).Several studies have reported low iron levels in patients with idiopathic PAH,and iron deficiency is an important risk factor.This article reviews PH associated with hematological disorders and its mechanism:and iron homeostasis and its relevance to PH. | Rajamma Mathew Jing Huang Joseph M Wu John T Fallon Michael H Gewitz | 2016 | World Journal of Cardiology2016，8，12： | 6 |
| 3 | Prevalence of amblyopia among preschool children in central south China显示文摘AIM: To determine the prevalence and factors associated with amblyopia among children aged 30-83 mo in central south of China.METHODS: A population-based, cross-sectional study was conducted in children aged 30-83 mo in Changsha(an urban city) and Zhangjiajie(a rural area) in central south of China. Clinical examinations including ocular alignment, ocular motility, visual acuity(VA), prism cover test, cycloplegic refraction, slit lamp examination and fundus examination were performed by trained study ophthalmologists and optometrists. Unilateral amblyopia was defined as a 2-line difference between eyes with VA<20/32 in the worse eye and with coexisting anisometropia [≥1.00 D spherical eutivalent(SE) for hyperopia, ≥3.00 D SE for myopia, and ≥1.50 D for astigmatism], strabismus, or past or present visual axis obstruction. Bilateral amblyopia was defined as VA in both eyes <20/40(≥ 48-month-old) and <20/50(< 48-month-old), with coexisting hyperopia ≥4.00 D SE, myopia ≤-6.00 D SE, and astigmatism ≥2.50 D, or past or present visual axis obstruction.RESULTS: There were 8042 children enrolled and 7713 children were screened. The amblyopia prevalence in children aged 30-83 mo was 1.09%(95% confidence interval, 0.86%-1.35%) with no age(P=0.81), gender(P=0.46) or area distribution(P=0.93) differences. Of these, 0.68% were unilateral cases and 0.41% were bilateral cases. Underlying causes included anisometropia(40%), binocular refractive error(36%), strabismus(14%) and deprivation(10%). Hyperopia combined with astigmatism was the frequent refractive error for ametropic and anisometropic amblyopia.CONCLUSION: In this rural and urban Chinese population, 1.09% of children with 30-83 mo of age had amblyopia, a prevalence rate similar to that of many other studies. Anisometropia and refractive error are the most common causes of unilateral and bilateral amblyopia respectively. | Yun-Ping Li Meng-Wen Zhou Susan H Forster Si-Ying Chen Xin Qi Hui-Ming Zhang Jing Luo | 2019 | International Journal of Ophthalmology(English edition)2019，12，5： | 5 |
| 4 | Premotor biomarkers for Parkinson's disease-a promising direction of research显示文摘The second most serious neurodegenerative disease is Parkinson’s disease(PD).Over the past several decades,a strong body of evidence suggests that PD can begin years before the hallmark clinical motor symptoms appear.Biomarkers for PD are urgently needed to differentiate between neurodegenerative disorders,screen novel therapeutics,and predict eventual clinical PD before the onset of symptoms.Some clinical evaluations and neuroimaging techniques have been developed in the last several years with some success in this area.Moreover,other strategies have been utilized to identify biochemical and genetic markers associated with PD leading to the examination of PD progression and pathogenesis in cerebrospinal fluid,blood,or saliva.Finally,interesting results are surfacing from preliminary studies using known PD-associated genetic mutations to assess potential premotor PD biomarkers.The current review highlights recent advances and underscores areas of potential advancement. | Brian R Haas Tessandra H Stewart Jing Zhang | 2012 | Translational Neurodegeneration2012，1，1： | 5 |

| 7 | Docosahexaenoic acid suppresses arachidonic acid-induced proliferation of LS-174T human colon carcinoma cells显示文摘AIM:To investigate the impact of arachidonic acid (AA) and docosahexaenoic acid (DHA) and their combination on colon cancer cell growth.METHODS:The LS-174T colon cancer cell line was used to study the role of the prostaglandin precursor AA and the omega-3 polyunsaturated fatty acid DHA on cell growth. Cell viability was assessed in XTT assays. For analysis of cell cycle and cell death,flow cytometry and DAPI staining were applied. Expression of cyclooxygenase-2 (COX-2),p21 and bcl-2 in cells incubated with AA or DHA was examined by real-time RT-PCR. Prostaglandin E2 (PGE2) generation in the presence of AA and DHA was measured using a PGE2-ELISA.RESULTS:AA increased cell growth,whereas DHAreduced viability of LS 174T cells in a time-and dose-dependent manner. Furthermore,DHA down-regulated mRNA of bcl-2 and up-regulated p21. Interestingly,DHA was able to suppress AA-induced cell proliferation and significantly lowered AA-derived PGE2 formation. DHA also down-regulated COX-2 expression. In addition to the effect on PGE2 formation,DHA directly reduced PGE2-induced cell proliferation in a dose-dependent manner. CONCLUSION:These results suggest that DHA can inhibit the pro-proliferative effect of abundant AA or PGE2. | Piet Habbel Karsten H Weylandt Katja Lichopoj Johannes Nowak Martin Purschke Jing-Dong Wang Cheng-Wei He Daniel C Baumgart Jing X Kang | 2009 | World Journal of Gastroenterology2009，15，9： | 2 |

| 11 | Quality control measures for lowering the seroconversion rate of hemodialysis patients with hepatitis B or C virus显示文摘BACKGROUND: Hemodialysis (HD) patients are at high risk of infection by hepatitis B virus (HBV) or hepatitis C virus (HCV). The present study was designed to determine the impact of quality control measures on the prevention of transmission of blood-borne viruses. METHODS: A total of 6182 adult maintenance HD patients from all HD units in Zhejiang Province were recruited on January 1, 2007. The baseline demographic and clinical characteristics were recorded and all patients were followed up until death or survival at 4 years later. The Quality Control Standards of Hemodialysis were gradually implemented in HD units. The HBV or HCV seroconversion rates of the recruited patients were calculated and compared every year during the observation period. RESULTS: The prevalence of HBV was 8.3% at the beginning of the study, and 6.6% for HCV. With the implementation of the HD quality control measures, the HBV seroconversion rate tended to decrease year by year (χ 2 =6.620, P=0.085), and the HCV seroconversion rate decreased significantly (χ 2 =10.41, P=0.015). Compared with the data in 2007, the HBV seroconversion rate (χ 2 =4.204, P=0.040, relative risk ratio 0.393, 95% CI 0.156-0.991) and the HCV seroconversion rate (χ 2 =7.373, P=0.007, relative risk ratio 0.386, 95% CI 0.189-0.787) decreased significantly in 2010. CONCLUSION: Quality control measures for HD decreased the seroconversion rates of HBV or HCV in HD patients, showing that updated quality control measures reduce the risk for transmission of blood-borne viruses in the HD population. | Jing Yuan,Yi Yang, Fei Han, Ping Zhang, Xiao-Ying Du, Hua Jiang and Jiang-Hua Chen The Kidney Disease Center, First Affiliated Hospital, Zhejiang University School of Medicine (Yuan J, Yang Y, Han F, Zhang P, Du XY, Jiang H and Chen JH) and Hemodialysis Quality Control Center of Zhejiang Province (Yuan J, Zhang P, Du XY and Chen JH), Hangzhou 310003, China | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，3： | 2 |

| 14 | Enhanced caveolin-1 expression in smooth muscle cells: Possible prelude to neointima formation显示文摘AIM: To study the genesis of neointima formation in pulmonary hypertension(PH), we investigated the role of caveolin-1 and related proteins. METHODS: Male Sprague Dawley rats were given monocrotaline(M, 40 mg/kg) or subjected to hypobaric hypoxia(H) to induce PH. Another group was given M and subjected to H to accelerate the disease process(M + H). Right ventricular systolic pressure, right ventricular hypertrophy, lung histology for medial hypertrophy and the presence of neointimal lesions were examined at 2 and 4 wk. The expression of caveolin-1 and its regulatory protein peroxisome proliferator-activated receptor(PPAR) γ, caveolin-2, proliferative and antiapoptotic factors(PY-STAT3, p-Erk, Bcl-x L), endothelial nitric oxide synthase(e NOS) and heat shock protein(HSP) 90 in the lungs were analyzed, and the results from M + H group were compared with the controls, M and H groups. Double immunofluorescence technique was used to identify the localization of caveolin-1 in pulmonary arteries in rat lungs and in human PH lung tissue. RESULTS: In the M + H group, PH was more severe compared with M or H group. In the 4 wk M+H group, several arteries with reduced caveolin-1 expression in endothelial layer coupled with an increased expression in smooth muscle cells(SMC), exhibited neointimal lesions. Neointima was present only in the arteries exhibiting enhanced caveolin-1 expression in SMC. Lung tissue obtained from patients with PH also revealed neointimal lesions only in the arteries exhibiting endothelial caveolin-1 loss accompanied by an increased caveolin-1 expression in SMC. Reduction in e NOS and HSP90 expression was present in the M groups(2 and 4 wk), but not in the M + H groups. In both M groups and in the M + H group at 2 wk, endothelial caveolin-1 loss was accompanied by an increase in PPARγ expression. In the M + H group at 4 wk, increase in caveolin-1 expression was accompanied by a reduction in the PPARγ expression. In the H group, there was neither a loss of endothelial caveolin-1, eNOS or HSP 90, nor an increase in SMC caveolin-1 expression; or any alteration in PPARγ expression. Proliferative pathways were activated in all experimental groups. CONCLUSION: Enhanced caveolin-1 expression in SMC follows extensive endothelial caveolin-1 loss with subsequent neointima formation. Increased caveolin-1 expression in SMC, thus, may be a prelude to neointima formation. | Jing Huang John H Wolk Michael H Gewitz James E Loyd James West Eric D Austin Rajamma Mathew | 2015 | World Journal of Cardiology2015，7，10： | 2 |
