| 1 | 脑缺血后N-myc下游调控基因2保护血脑屏障完整性显示文摘脑缺血后血脑屏障(BBB)的破坏与外周细胞向脑内浸润、病孔损形成与进展、以及临床病程恶化密切相关。目前BBB完整性的调控机制,尤其是在永久性缺血后的调控机制尚未明确。本研究使用小鼠永久性脑缺血模型进行相关研究,结果显示,星形胶质细胞N-myc下游调控基因2(NDRG2)可能是缺血性脑卒中后BBB通透性的调控分子,该分子与分化和应激相关。免疫组化显示,在永久性大脑中动脉闭塞(MCAO)后,NDRG2在星形胶质细胞中的表达显著增加。敲除NDRG2基因,脑梗死体积增加,免疫细胞在缺血同侧大脑半球积聚增加。MCAO后,NDRG2基因敲除小鼠缺血侧皮质的缺血灶内及灶周血管周围区域内的血清蛋白(包括纤维蛋白原和免疫球蛋白)的外渗增强此之,MCAO后NDRG2基因敲除小鼠体内基质金属蛋白酶(MMPs)的表达也显著增加。在细胞培养中,NDRG2-/-星形胶质细胞中MMP-3的表达和分泌增加,这种增加可被腺病毒介导的NDRG2再表达所逆转。综上所述,脑缺血后,星形胶质细胞内的NDRG2可能通过调节MMP的表达,而在BBB通透性的调节和免疫细胞浸润中起到重要作用。 | Takarada-Iemata M Yoshikawa A Ta HM Okitani N Nishiuchi T Aida Y Kamide T Hattori T Ishii H Tamatani T Le TM Roboon J Kitao Y Matsuyama T Nakada M Hori O 聂昊 | 2018 | 神经损伤与功能重建2018,13,4: | 4 |
| 2 | Relationship between skin fold thickness and insulin resistance in the essential hypertensive patients in Vietnam显示文摘Previous studies reported a close relationship between obesity and insulin resistance in the essential hypertensive patients. Objective In this study, we examined the relationship between the skin fold thickness and insulin resistance then developed a formula to estimate the insulin resistance index according to the skin fold thickness in the essential hypertensive patients. Subjects and Methods Medical records of 80 patients (37 males, 43 females) were reviewed and the data were tabulated. Anthropometric indexes (including height, weight, waist circumference, hip circumference, and skins fold thickness at 5 fatty difference points on the Erdheim diagram), fasting plasma glucose and insulin concentration were recorded. The mean age was 57.0±9.2 years. The insulin resistance index was calculated following the Homeostasis Model Assessment (HOMA) formula. Results Compared with the group with BMI<23kg/m2, the group with BMI≥23 kg/m2 had higher fasting insulin concentration (8.85 ± 4.97 pmol/L vs 15.60 ± 8.70 pmol/L, P<0.001 ) and higher insulin resistance index in (2.15±1,24 vs 3.76±2.22, P<0.001). No significant difference in fasting plasma insulin concentration,insulin resistance index between male and female was observed (P>0.05). There was a positive correlation between skin fold thickness and the fasting insulin concentration and insulin resistance index. The skin fold thickness at point A8 had the best coefficient correlated with fasting plasma insulin(r=0.79, P<0.001) and insulin resistance index (r= 0.79, P < 0.001). A formula to estimate the insulin resistance index by skin fold thickness at point A8 as: Insulin resistance index = 0.12 × [skin fold thickness at A8 point (mm)] - 1.Conclusion: In the essential hypertensive patients, the formula to estimate insulin resistance index as 0.12 × [skin fold thickness at A8 point (mm)]-1 may predict accurately the level of insulin resistance. | Toan C Nguyen Khoa TA Pham Quyen TL Do Cuong T Nguyen Diep D Nguyen Vinh G Le Cong D Nguyen | 2005 | Journal of Geriatric Cardiology2005,2,4: | 4 |

| 4 | Surgical stress and cytoskeletal changes in lens epithelial cells following manual and femtosecond laser-assisted capsulotomy显示文摘AIM:To study the effect of mechanical stress on the cytoskeleton in lens epithelial cells following conventional phacoemulsification surgery(CPS)and femtosecond laserassisted cataract surgery(FLACS).METHODS:The cytoskeleton of the epithelial cells of the anterior lens capsules(ALC)removed by CPS and FLACS was examined by immunohistochemistry.Expression of the intermediate filament,glial fibrillary acidic protein(GFAP),and glutamine synthetase(GS)immunoreactivity were detected.In order to map the actin network of cells,fluorescently labeled phalloidin was used.The samples were examined using confocal laser scanning microscopy.RESULTS:GFAP expression was visible in a larger number of the epithelial cells after CPS compared to FLACS.In CPS sample’s epithelial cells,GFAP immunoreactivity indicated robust morphological change.Regarding the actin filaments,the presence of tubular elements connecting epithelial cells,regular actin pattern and marked cortical network after CPS were found.Following FLACS,the actin cytoskeleton of the epithelial cells remained densely structured,and the tubular elements were undetectable,however,the above-mentioned regular actin pattern and the marked cortical network were visible.CONCLUSION:The conventional removal of the ALC induces more robust changes of the cytoskeleton of the lens epithelial cells. | ANDrea Krisztina Sükosd Krisztina Szabadfi Edina Szabó-Meleg Beáta Gáspár Pavel Stodulka Gyorgy SétálóJr Róbert Gábriel Miklós Nyitrai Zsolt Biró Hajnalka Abrahám | 2020 | International Journal of Ophthalmology(English edition)2020,13,6: | 2 |
| 5 | Skin fold thickness at abdomen:a simple anthropometric measurement may compliment metabolic syndrome definition in patients with normal waist circumference显示文摘Backgroud and Objectives Previous studies have reported that skin fold thickness (SF) strongly correlated with insulin resistance in the metabolic syndrome (MetS). In this study, we developed a MetS definition by SF at A8 point (SFA8) on Erdheim diagram(MetSSFA8) in essential hypertensive patients. Subjects and Methods Medical records of 268 essential hypertensive patients (126males and 122 females) were analyzed, including 210 non-diabetic patients (NDM group) and 58 patients with diabetes (DM group).The mean age was 61.4 ± 9.9 and 59.0 ± 11.0 years, respectively. The control group consisted of 90 non-diabetic, non-hypertensive patients with a mean age of 58.0 ± 11.3 years. The proposed MetSSFA8 definition included SFA8 specific values ( ≥30 mm in female and ≥27 mm in male) and at least two of the following: raised triglyceride levels ( ≥1.7 mmol/L), or specific treatment for this lipid abnormality; raised blood pressure (SBP≥130 mmHg and/or DBP≥85 mmHg), or treatment of previously diagnosed hypertension;reduced HDL-cholesterol (< 1.03 mmol/L in men, <1.29 mmol/L in women), or specific treatment for this lipid abnormality; raised fasting plasma glucose (≥5.6 mmol/l), or previously diagnosed DM. Metabolic Syndrome by the National Cholesterol Education Program and International Diabetes Federation definitions were determined with abdominal obesity defined by Asia-Pacific criteria for waist circumference (NCEPA and IDFA). Results The percentage of MetS as defined by NCEPA, IDFA and MetSSFA8 in NDM group was lower than that of NCEPA, IDFA and MetSSFA8 in DM group [OR=7.7 (95%CI, 2.9-20.2) and 2.5 (95%CI, 1.4-4.8) and 2.7(95%CI, 1.3-5.6), respectively] and higher than that of the control group [OR=53.3 (95%CI, 16.7-170.6), 5.8 (95%CI, 2.6-13.2) and18.8 (95%CI, 7.3-48.7), respectively]. The percentage of MetS by NCEPA, IDFA and MetSSFA8 in males in NDM group was lower than the percentage of MetS by NCEPA, IDFA and MetSSFA8 in females in NDM group (50.8% and 77.9%, P< 0.001; 15,9% and 67.2%, P< 0.001; 60.3% and 73.8%, P <0.05, respectively). In subjects with normal WC or both normal WC and BMI, the percentage of MetS by SFAS was higher than that the percentage of MetS by NCEPA (36.9% and 50.8%, P< 0.05 and 36.0% and 51.0%, P< 0.05).The sensitivity, specificity, false positive rate, positive predictive value, negative predictive value of MetSSFA8 assessed with NCEPA definitions were 0.87, 0.73, 0.27, 0.79 and 0.82, respectively. There was a close agreement between MetSSFA8 and NCEPA (The coefficient of Kapa was 0.60, P< 0.001). Conclusions The MetSSFA8 definition was developed which may be useful in order to define and manage MetS in patients with normal WC or normal weight. | Toan C Nguyen Thai Q Ngo Son V Nguyen Hieu T Luong Khoa TA Pham Cong D Nguyen | 2006 | Journal of Geriatric Cardiology2006,3,2: | 2 |
| 6 | Involvement of serum retinoids and Leiden mutation in patients with esophageal, gastric, liver, pancreatic, and colorectal cancers in Hungary显示文摘AIM: To analyze the serum levels of retinoids and Leiden mutation in patients with esophageal, gastric, liver,pancreatic, and colorectal cancers.METHODS: The changes in serum levels of retinoids (vitamin A, α- and β-carotene, α- and β-cryptoxanthin,zeaxanthin, lutein) and Leiden mutation were measured by high liquid performance chromatography (HPLC)and polymerase chain reaction (PCR) in 107 patients (70 males/37 females) with esophageal (0/8), gastric (16/5), liver (8/7), pancreatic (6/4), and colorectal (30/21including 9 patients suffering from in situ colon cancer)cancer. Fifty-seven healthy subjects (in matched groups)for controls of serum retinoids and 600 healthy blood donors for Leiden mutation were used.RESULTS: The serum levels of vitamin A and zeaxanthin were decreased significantly in all groups of patients with gastrointestinal (GI) tumors except for vitamin A in patients with pancreatic cancer. No changes were obtained in the serum levels of α- and β-carotene,α- and β-cryptoxanthin, zeaxanthin, lutein in patients with GI cancer. The prevalence of Leiden mutation significantly increased in all groups of patients with GI cancer.CONCLUSION: Retinoids (as environmental factors)are decreased significantly with increased prevalence of Leiden mutation (as a genetic factor) in patients before the clinical manifestation of histologically different (planocellular and hepatocellular carcinoma, and adenocarcinoma) GI cancer. | Gyula Mózsik Gy(o|¨)rgy Rumi András D(o|¨)m(o|¨)t(o|¨)r Mária Figler Beáta Gasztonyi El(?)d Papp Alajos Pár Gabriella Pár József Belágyi Zoltán Matus Béla Melegh | 2005 | World Journal of Gastroenterology2005,11,48: | 2 |
