2Spatiotemporal variations of PM_(2.5) and PM_(10) concentrations between31 Chinese cities and their relationships with SO_2,NO_2,CO and O_3显示文摘The variations of mass concentrations of PM_(2.5),PM_(10),SO_2,NO_2,CO,and O_3 in 31 Chinese provincial capital cities were analyzed based on data from 286 monitoring sites obtained between March 22,2013 and March 31,2014.By comparing the pollutant concentrations over this length of time,the characteristics of the monthly variations of mass concentrations of air pollutants were determined.We used the Pearson correlation coefficient to establish the relationship between PM_(2.5),PM_(10),and the gas pollutants.The results revealed significant differences in the concentration levels of air pollutants and in the variations between the different cities.The Pearson correlation coefficients between PMs and NO_2 and SO_2 were either high or moderate(PM_(2.5) with NO_2:r=0.256-0.688,mean r=0.498;PM_(10) with NO_2:r = 0.169-0.713,mean r = 0.493;PM2.5 with SO_2:r= 0.232-0.693,mean r=0.449;PM_(10) with SO_2:r = 0.131-0.669,mean r=0.403).The correlation between PMs and CO was diverse(PM_(2.5):r = 0.156-0.721,mean r=0.437;PM_(10):r=0.06-0.67,mean r= 0.380).The correlation between PMs and O_3 was either weak or uncorrelated(PM_(2.5):r--0.35 to 0.089,mean r=-0.164;PM_(10):r=-0.279 to 0.078,mean r=-0.127),except in Haikou(PM2.5:r=0.500;PM_(10):r-0.509).Yangyang Xie Bin Zhao Lin Zhang Rong Luo 2015Particuology2015,13,3:56
3Immunohistochemical study on p53,H-rasp21,c-erbB-2 protein and PCNA expression in HCC tissues of Hart and minority ethnic patients显示文摘AIM To find out the difference of humanprimary liver carcinogenesis between Han andminority ethnic patients in Xinjiang.METHODS Expression of p53,c-erbB-2,H-rasp21 protein and proliferating cell nuclearantigen(PCNA)in tumor tissues of 50 patients(Han 38,minority 12)with primary hepaticcarcinoma was detected byimmunohistochemistry(LSAB).RESULTS The positive frequency of p53,c-erbB-2,H-rasp21 and PCNA expression was46.0%(23/50),70.0%(35/50),68.0%(34/50)and 82.0%(41/50)in tumor tissues;4.0%(2/50),22.0%(11/50),64.0%(32/50)and 52.0%(26/ 50)in peritumors respectively and asignificant difference,except for H-rasp21,ofoncogene alteration was found(P<0.05)between tumor and non-tumorous tissues.Combined the three oncogenes alteration,26%(13/50)tumor tissues had positiveimmunoreactivity,but in peritumor and normallivers it was negative.The positive rate of p53,c-erbB-2 and H-rasp21 protein expression was39.5%(15/38),60.5%(23/38)and 39.5%(15/38)in tumors of Han patients;66.7%(8/12),100%(12/12)and 75.0%(9/12)in minoritiesrespectively,with statistical difference (P<0.05).CONCLUSION Overexpression of p53,c-erbB-2and H-rasp21 in human primary liver carcinoma isan important biomarker of genetic alteration.The different frequency of these oncogeneticchanges may reflect some environmental or/andethnic hereditary factors affecting the livercarcinogenesis.The special life style of Han,Uygur,Kazak and Mongolia nationalities inXinjiang may also be related to theetiopathogenesis of this disease.Guo Yue Lin Zhao Lun Chen Cai Mo Lu Ying Li Xiao Jia Ping Rong Huang Department of Laboratory Medicine,Chinese PLA 474 Hospital,Urumqi 830011,Xinjiang Uygur Autonomic Region,China Department of Pathology,the 1st Teaching Hospital,Xinjiang Medical University,Urumqi 830054,Xinjiang Uygur Autonomic Region,China 2000World Journal of Gastroenterology2000,6,2:40
4China National Medical Products Administration approval summary:anlotinib for the treatment of advanced non-small cell lung cancer after two lines of chemotherapy显示文摘Background:On May 8,2018,the China National Medical Products Administration(NMPA)approved anlotinib,an orally administered anti-angiogenesis inhibitor,for the treatment of patients with advanced non-small cell lung can-cer(NSCLC)who have progressed after treatment with two or more lines of prior systemic chemotherapy.Main body of the abstract:China NMPA reviewed and inspected a regional double-blinded,placebo-controlled,Phase III trial comparing the overall survival(OS)of NSCLC patients between the anlotinib and placebo arms.A total of 437 patients were randomized(2:1)to receive either anlotinib(n=294)or placebo(n=143)once daily on a 2-week on and 1-week off schedule.Patients with epidermal growth factor receptor(EGFR)or activating anaplastic lymphoma kinase(ALK)genomic tumor aberrations should have disease progression on NMPA-approved therapy.Anlotinib is the first NMPA-approved drug for patients with advanced NSCLC who have progressed on at least two lines of prior systemic chemotherapies in China.The approval was based on a statistically and clinically significant improvement in median OS with anlotinib(9.46 months)compared with placebo[6.37 months;hazard ratio(HR])=0.70,95%confidence interval(CI)=0.55-0.89;two-sided log-rank P=0.002].The confirmed objective response rate(ORR)was 9.2%in the anlotinib arm and 0.7%in the placebo arm.The median duration of response(DoR)was 4.83 months,with a 95%CI of 3.31-6.97 months.The toxicity profile of anlotinib was consistent with that of known anti-angiogenesis inhibitors.Common adverse drug reactions(ADRs)in anlotinib-treated patients included hypertension(67.4%),hand-foot syndrome(43.9%),hemoptysis(14.0%),thyroid stimulating hormone(TSH)elevation(46.6%),and corrected QT interval(QTc)prolongation(26.2%).Short conclusion:Anlotinib demonstrated a clinically significant OS prolongation as a novel therapeutic option for advanced or metastatic NSCLC following at least two lines of chemotherapy.Ming Zhou Xiaoyuan Chen Hong Zhang Lin Xia Xin Tong Limin Zou Ruimin Hao Jianhong Pan Xiao Zhao Dongmei Chen Yuanyuan Song Yueli Qi Ling Tang Zhifang Liu Rong Gao Yuankai Shi Zhimin Yang 2019Cancer Communications2019,39,1:35

6Astragalus polysaccharide attenuates rat experimental colitis by inducing regulatory T cells in intestinal Peyer's patches显示文摘AIM: To explore probable mechanism underlying the therapeutic effect of Astragalus polysaccharide(APS) against experimental colitis.METHODS: Thirty-two Sprague-Dawley rats were randomly divided into four groups. Colitis was induced with 2, 4, 6-trinitrobenzene sulfonic acid(TNBS). The rats with colitis were treated with 400 mg/kg of APS for 7 d. The therapeutic effect was evaluated by colonic weight, weight index of the colon, colonic length, and macroscopic and histological scores. The levels of regulatory T(Treg) cells in Peyer's patches were measured by flow cytometry, and cytokines in colonic tissue homogenates were analyzed using enzyme-linked immunosorbent assay. The expression of related orphan receptor-gt(ROR-gt), IL-23 and STAT-5a was measured by Western blot.RESULTS: After 7-d treatment with APS, the weight index of the colon, colonic weight, macroscopical and histological scores were decreased, while the colonic length was increased compared with the model group. The expression of interleukin(IL)-2, IL-6, IL-17, IL-23 and ROR-gt in the colonic tissues was down-regulated, but Treg cells in Peyer's patches, TGF-β and STAT5 a in the colonic tissues were up-regulated.CONCLUSION: APS effectively ameliorates TNBSinduced experimental colitis in rats, probably through restoring the number of Treg cells, and inhibiting IL-17 levels in Peyer's patches.Hai-mei Zhao Yan Wang Xiao-Ying Huang min-fang Huang Rong Xu Hai-Yang Yue Bu-gao Zhou Hong-Yan Huang Qi-meng Sun Duan-Yong Liu 2016World Journal of Gastroenterology2016,22,11:28
7Possible early Neoproterozoic magmatism associated with slab window in the Pingshui segment of the Jiangshan-Shaoxing suture zone: Evidence from zircon LA-ICP-MS U-Pb geochronology and geochemistry显示文摘We report here geochemical data, U-Pb zircon ages, and Hf isotopes for the high-Mg diorites (HMDs), Nb-enriched basaltic porphyrys (NEBPs) and plagiogranites (PLAGs) in the Pingshui segment of the Jiangshan-Shaoxing suture zone. The HMDs are characterized by high Mg# (>60), high Na and LREE contents, depletion of HREE and HFSE, and pronounced positive εNd(t) values of 7.0 to 7.7, similar to some adakitic high-Mg andesites. The NEBPs are relatively Na-rich (Na2O/K2O>6) and display high abundances of P2O5 (~1.00%), TiO2 (~3.08%) and HFSE (e.g., Nb=9.53-10.27 ppm). Their Nd isotopic compositions (εNd(t)=6.8-8.0) are comparable to those of the HMDs. The PLAGs are metaluminous (A/CNK=0.84-0.89) and sodic (Na2O/K2O>10). Their depletion in HFSE (e.g., Nb, Ta) is consistent with 'SSZ-type' plagiogranite. Zircon LA-ICP-MS U-Pb dating yields an age of 932±7 Ma for the HMD, 916±6 Ma for the NEBP, and 902±5 Ma for the PLAG, respectively, indicating that they were products of early Neoproterozoic magmatism. The PLAGs exhibit relatively high zircon Hf isotopes and positive εHf(t) values of 11.0 to 16.2, consistent with their Nd isotopic data (εNd(t)=7.5-8.4). Such features are similar to those of oceanic plagiogranites in ophiolites and distinct from those of crust-derived granites. The PLAGs were most likely derived from partial melting of subducted oceanic crust in an active continental margin. Considering these results in the context of the regional geology, we suggest that a slab window in the subducting oceanic crust between the Yangtze Block and Cathaysia Block was possibly the principal cause for the unique arc magmatism in the area. The upwelling asthenosphere below the slab window may have provided significant thermodynamic conditions.CHEN ZhiHong GUO KunYi DONG YongGuan CHEN Rong LI LongMing LIANG YiHong LI ChunHai YU XiMing ZHAO Ling XING GuangFu 2009Science China Earth Sciences2009,52,7:26
8Microvessel density is a prognostic marker of human gastric cancer显示文摘AIM: To investigate whether microvessel density (MVD) is related with prognosis in gastric cancer patients, and the expression of cyclooxygenase-2 (COX-2) and vessel endothelial growth factor (VEGF) so as to determine the possible role of COX-2 and VEGF in gastric cancer angiogenesis.METHODS: Forty-seven formalin-fixed paraffin-embedded tissue samples of gastric cancer were evaluated for COX-2, VEGF by immunohitochemical staining. To assess tumor angiogenesis, MVD was determined by immunohitochemical staining of endothelial protein factor Ⅷ-related antigen. The relationship among COX-2 and VEGF expression, MVD, and clinicopathologic parameters was analyzed. RESULTS: Among the 67 samples, high MVD was significantly associated with lymph node metastasis and poor survival. Multivariate survival analysis showed that MVD value and lymph node metastasis were independent prognostic factors. The expression rate of COX-2 and VEGF was significantly higher than that of the adjacent tissues. COX-2 and VEGF expression in gastric cancer was significantly correlated with tumor differentiation and depth of invasion, but not with survival. The mean MVD value of COX-2 or VEGF positive tumors was higher than that of COX-2 or VEGF negative tumors. A significant correlation was found between the expressions of COX-2and VEGF. CONCLUSION: MVD may be one of the important prognostic factors for gastric cancer patients. COX-2 and VEGF may play an important role in tumor progression by stimulating angiogenesis. VEGF might play a main role in the COX-2 angiogenic pathway. The inhibition of angiogenesis or COX-2, VEGF activity may have an important therapeutic benefit in the control of gastric cancer.Hong-Chuan Zhao Rong Qin Xiao-Xin Chen Xia Sheng Ji-Feng Wu Dao-Bin Wang Gui-Hua Chen 2006World Journal of Gastroenterology2006,12,47:25

11Moxibustion combined with acupuncture increases tight junction protein expression in Crohn's disease patients显示文摘AIM:To investigate the effect of herb-partitioned moxibustion combined with acupuncture on the expression of intestinal epithelial tight junction(TJ) proteins.METHODS:Sixty patients diagnosed with mild to moderate Crohn’s disease(CD)were allocated into the herb-partitioned moxibustion combined with acupuncture(HMA)group(n=30)or the mesalazine(MESA)group(n=30)using a parallel control method.There were 2 sets of acupoints used alternately for HMA treatment.The following points were included in Set A:ST25(Tianshu),RN6(Qihai),and RN9(Shuifen)for herb-partitioned moxibustion and ST36(Zusanli),ST37(Shangjuxu),LI11(Quchi),and LI4(Hegu)for acupuncture.The points for Set B included BL23(Shenshu)and BL25(Dachangshu)for herb-partitioned moxibustion and EX-B2 of T6-T1(Jiajixue)fo r acupuncture.The patients received the same treatment6 times a week for 12 consecutive weeks.The MESA group received 1 g of mesalazine enteric coated tablets4 times daily for 12 consecutive weeks.Intestinaltissues were stained and examined to compare the morphological and ultrastructural changes before and after the treatment session.Immunohistochemistry and in situ hybridization assays were used to detect the expression of intestinal epithelial TJ proteins zonula occludens-1(ZO-1),occludin,and claudin-1.The m RNA levels were also evaluated.RESULTS:After the treatment,both herb-partitioned moxibustion combined with acupuncture and mesalazine improved intestinal morphology and ultrastructure of CD patients;the patients treated with HMA showed better improvement.HMA significantly increased the expression of ZO-1(P=0.000),occludin(P=0.021),and claudin-1(P=0.016).MESA significantly increased the expression of ZO-1(P=0.016)and occludin(P=0.026).However,there was no significant increase in the expression of claudin-1(P=0.935).There was no statistically significant difference between the two groups for the expression of occludin and claudin-1(P>0.05).The HMA group showed a significant improvement in ZO-1 expression compared to the MESA group(2333.34±352.51 vs 2160.38±307.08,P=0.047).HMA significantly increased the expression of ZO-1 m RNA(P=0.000),occludin m RNA(P=0.017),and claudin-1 m RNA(P=0.017).MESA significantly increased the expression of ZO-1 m RNA(P=0.000),occludin m RNA(P=0.042),and claudin-1 m RNA(P=0.041).There was no statistically significant difference between the two groups in the expression of occludin and claudin-1 m RNA(P>0.05).However,the HMA group showed a significant improvement in ZO-1 m RNA expression compared with the MESA group(2378.17±308.77 vs 2200.56±281.88,P=0.023).CONCLUSION:HMA can repair intestinal epithelial barrier lesions and relieve inflammation by upregulating the expression of TJ proteins and their m RNAs.Hai-Xia Shang An-Qi Wang Chun-Hui Bao Huan-Gan Wu Wei-Feng Chen Lu-Yi Wu Rong Ji Ji-Meng Zhao Yin Shi 2015World Journal of Gastroenterology2015,21,16:23
12Hypoglycemic and Hypolipidemic Effects of Lycium barbarum Polysaccharide in Diabetic Rats显示文摘Objective To study the antidiabetic effects and the underlying molecular mechanisms of Lycium barbarum polysaccharide(LBP) and its DEAE cellulose elution fraction LBP-IV in diabetic rats induced by high fat diet(HFD) and streptozotocin(STZ). Methods After ig administration of LBP-IV [50, 100, and 200 mg/(kg·d)] and LBP [100 mg/(kg·d)] once daily for consecutive 4 weeks to diabetic rats, the glucose and lipids in blood, m RNA expression of phosphoenolpyruvate carboxykinase(PEPCK), sterol regulatory element binding-protein-1c(SREBP-1c), and fatty acid synthase(FAS) in liver were determined. Results Ig administration of LBP and LBP-IV significantly decreased the levels of blood glucose, Hb A1 c, TC, TG, and LDL-C, as well as the hepatic m RNA expression of PEPCK, SREBP-1c, and FAS, whereas significantly increased the oral glucose tolerance of diabetic rats. Conclusion The findings suggest that the antidiabetic effects of LBP and LBP-IV are associated with the decreased hepatic m RNA expression of PEPCK, SREBP-1c, and FAS in HFD-STZ induced diabetic rats.Rong Zhao Rui Jin Yong Chen Feng-mei Han 2015Chinese Herbal Medicines2015,7,4:22
13Application of nonlinear chemical fingerprinting to identification,evaluation and clinical use of Glycyrrhiza显示文摘Nonlinear chemical fingerprinting is a new technique for analyzing traditional Chinese medicines (TCMs). We developed such a method and applied it to Glycyrrhiza, a significant TCM. Nonlinear chemical fingerprints were obtained for Glycyrrhiza from four different production areas, and for 14 other TCMs with similar induction time. The calculation of their similarities was based on similarity system theory. Using intuitive visual comparison of the data and the similarity calculation results, Glycyrrhiza was discriminated from the 14 other TCMs. There was a linear relationship between the content of active TCM components and the induction time. This was used to compare the content of active components in Glycyrrhiza from the four different production areas, and establish an equivalent-dose relationship for these four samples. This method provides a new tool for discrimination and evaluation of Glycyrrhiza, and a dosage reference for clinical application of Glycyrrhiza from the four regions studied.FANG XuanQi ZHANG TaiMing ZHAO Zhe XIANG FengQin LIANG YiZeng WANG Mei ZHU Rong CHEN Su QIAO JunXi 2010Chinese Science Bulletin2010,55,26:20
14BMI, WC, WHtR, VFI and BFI: Which Indictor is the Most Efficient Screening Index on Type 2 Diabetes in Chinese Community Population显示文摘Objective Obesity is a major risk factor for type 2 diabetes, many indexes can be used to describes obesity and predict diabetes. This research attempts to identify the best indicator of obesity to screening diabetes in Chinese population. Methods A cross-sectional data of 8121 subjects aged 35-60 years were included in this research belongs to the Diabetes Appropriate Technology Intervention Study. Anthropometric indicators including body weight, height, waist circumferences (WC), body fat index (BFI) and visceral fat index (VFI) and blood biochemical indicators after an overnight fast [fasting blood glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triacylglycerol] were measured. BMI (body mass index) and Weight to Height Ratio was calculated. Results Subjects with obesity had a higher risk of physician diagnosed diabetes (OR=2.50, 95% CI 1.83-3.43), new diagnosed diabetes (OR=4.23, 95% CI 2.91-6.15) and pre-diabetes (OR=1.75, 95% CI 1.31-2.34) compared to those with normal Body mass index (BMI). There was a significant trend of increased risk of all diabetes status with increased waist circumference (WC). The waist-to-height ratio (WHtR) yielded the most significant association with new diagnosed diabetes and physician diagnosed diabetes than other indices. Conclusion Central obesity is significantly correlated with diabetes. VFI was most correlated with pre-diabetes while WHtR is an efficient screening index than BMI and WC in Chinese community diabetes screening.MI Sheng Quan YIN Peng HU Nan LI Jian Hong CHEN Xiao Rong CHEN Bo YAN Liu Xia ZHAO Wen Hua 2013Biomedical and Environmental Sciences2013,26,6:20
15Degradation of sulfadiazine antibiotics by water falling film dielectric barrier discharge显示文摘A new water falling film dielectric barrier discharge was applied to the degradation of sulfadiazine in the aqueous solution. The various parameters that affect the degradation of sulfadiazine and the proposed evolutionary process were investigated. The results indicated that the inner concentrations of 10 mg/L sulfadiazine can be all removed within 30 min. The optimum pH value was 9.10 and both strong acidic and alkaline solution conditions were not suitable for the degradation. The degradation of sulfadiazine can be enhanced by the addition of hydrogen radical scavengers, but be inhibited by adding hydroxyl radical scavengers. The water falling film dielectric barrier discharge was rather ineffective in mineralization, because of the intermediates were recalcitrant to be degraded. The existence of Fe2+and CCl4 in the liquid phase can promote the degradation and mineralization of sulfadiazine. It was found that the degradation of SDZ was enhanced by CCl4 was mainly because of the increase of OH due to the reaction of CCl4 with H that reduce the chances of their recombination with OH. Based on the 8 intermediate products identified by LC–MS, the proposed evolution of the degradation process was investigated.Shao-Peng Rong Ya-Bing Sun Ze-Hua Zhao 2014Chinese Chemical Letters2014,25,1:18
16Association between Ambient Air Pollution and Hospital Emergency Admissions for Respiratory and Cardiovascular Diseases in Beijing: a Time Series Study显示文摘Objective To investigate the association between ambient air pollution and hospital emergency admissions in Beijing. Methods In this study, a semi-parametric generalized additive model(GAM) was used to evaluate the specific influences of air pollutants(PM10, SO2, and NO2) on hospital emergency admissions with different lag structures from 2009 to 2011, the sex and age specific influences of air pollution and the modifying effect of seasons on air pollution to analyze the possible interaction. Results It was found that a 10 μg/m3 increase in concentration of PM10 at lag 03 day, SO2 and NO2 at lag 0 day were associated with an increase of 0.88%, 0.76%, and 1.82% respectively in overall emergency admissions. A 10 μg/m3 increase in concentration of PM10, SO2 and NO2 at lag 5 day were associated with an increase of 1.39%, 1.56%, and 1.18% respectively in cardiovascular disease emergency admissions. For lag 02, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 were associated with 1.72%, 1.34%, and 2.57% increases respectively in respiratory disease emergency admissions. Conclusion This study further confirmed that short-term exposure to ambient air pollution was associated with increased risk of hospital emergency admissions in Beijing.ZHANG Ying WANG Shi Gong MA Yu Xia SHANG Ke Zheng CHENG Yi Fan LI Xu NING Gui Cai ZHAO Wen Jing LI Nai Rong 2015Biomedical and Environmental Sciences2015,28,5:18
17An Integrated Analysis of Risk Factors of Cognitive Impairment in Patients with Severe Carotid Artery Stenosis显示文摘Objective To investigate cognitive dysfunction in patients with carotid artery stenosis(CAS) and potential risk factors related to cognitive-especially memory-dysfunction. Methods Forty-seven patients with carotid artery stenosis were recruited into our study cohort. The Mini-Mental State Examination(MMSE) and the Montreal Cognitive Assessment(MoCA) were adopted to assess cognitive function, the Wechsler Memory Scale(WMS) to assess memory function, high-resolution MRI and enhanced ultrasound to evaluate carotid plaques, and computed tomography perfusion(CTP) imaging to evaluate intracranial blood perfusion. Single-factor analysis and multiple-factor regression analysis were used to analyze potential risk factors of cognitive impairment. Results Mini-Mental State Examination test results showed that 22 patients had cognitive impairment, and MoCA test results showed that 10 patients had cognitive impairment. Analysis of various risk factors indicated that the average memory quotient of female patients was higher than that of males(P = 0.024). The cognitive and memory performance of those with an educational background above high school were significantly better than those of participants with high school or lower(P = 0.045). Patients with abnormal intracranial perfusion performed worse on the MMSE test(P = 0.024), and their WMS scores were significantly lower(P = 0.007). The MMSE scores and the memory quotients were significantly lower in patients with a history of cerebral infarction(MMSE, P = 0.047, memory quotient score, P = 0.018). Conclusion A history of cerebral infarction and abnormal cerebral perfusion are associated with decline in overall cognitive function and memory in patients with carotid stenosis. Being female and having an educational background above high school may be protective factors in the development of cognitive dysfunction.LUO Ru Tao WANG Pei Jiong DENG Xiao Feng ZHOU Shu Jie ZHAO Meng QIAN Jing ZHANG Dong WANG Rong ZHANG Yan 2018Biomedical and Environmental Sciences2018,31,11:17
18Blending Scheduling under Uncertainty Based on Particle Swarm Optimization Algorithm显示文摘Blending is an important unit operation in process industry. Blending scheduling is nonlinear optimiza- tion problem with constraints. It is difficult to obtain optimum solution by other general optimization methods. Particle swarm optimization (PSO) algorithm is developed for nonlinear optimization problems with both contin- uous and discrete variables. In order to obtain a global optimum solution quickly, PSO algorithm is applied to solve the problem of blending scheduling under uncertainty. The calculation results based on an example of gasoline blending agree satisfactory with the ideal values, which illustrates that the PSO algorithm is valid and effective in solving the blending scheduling problem.ZHAO Xiaoqiang(赵小强) RONG Gang(荣冈) 2005Chinese Journal of Chemical Engineering2005,13,4:16
19Recurrent gain-of-function USP8 mutations in Cushing's disease显示文摘库欣的疾病,引起过量皮质醇生产的也已知的同样促肾上腺皮质的荷尔蒙(ACTH )-secreting 垂体腺瘤(舞步) ,占多达 85%corticotrophin 依赖的库欣的症候群盒子。然而,在这疾病的基因改变是不清楚的。这里,我们执行了从 12 秘密 ACTH 舞步导出并且匹配血样品的 DNA 定序的 whole-exome,它在候选人基因揭示了体的变化的三种类型, USP8 (编码 ubiquitin 特定的朊酶 8 ) ,专门在 exon 14 在 12 秘密 ACTH 舞步中的 8 个。我们进一步评估了体的 USP8 变化在另外由定序的 Sanger 的 258 舞步。进一步定序指向在 108 秘密 ACTH 舞步(62.04%) 中的 67 个识别了 USP8 变体的 17 种类型的一个总数。然而,任何一个都没在舞步的另外的类型这些变化被检测(n = 150 ) 。这些变化在 USP8 的 14-3-3 绑定主题以内聚集并且破坏在 USP8 和 14-3-3 蛋白质之间的相互作用,导致保护 EGFR 免受 lysosomal 降级的伤害的一个提高的能力。因此,有 EGFR 表示,提高的 EGFR 蛋白质丰富和 mRNA 表示的更高的发生 POMC 铺平的变异的 USP8 显示的舞步,它编码 ACTH 的先锋。有变异的 USP8 的舞步在尺寸是显著地更小的并且比野类型的舞步有更高的 ACTH 生产。在里面通过手术 resected 主要变异 USP8 的肿瘤房间, USP8 击倒或堵住的 EGFR 有效地稀释 ACTH 分泌物。一起拿,体的 gain-of-function USP8 变化是普通的并且在库欣的疾病贡献 ACTH 生产过剩。USP8 或 EGFR 的抑制为对待变异 USP8 的 corticotrophin 腺瘤是有希望的。我们的学习在库欣的疾病加亮潜在地功能的变异的基因并且提供卓见进这疾病的治疗学。Zeng-Yi Ma Zhi-Jian Song Jian-Hua Chen Yong-Fei Wang Shi-Qi Li Liang-Fu Zhou Ying Mao Yi-Ming Li Rong-Gui Hu Zhao-Yun Zhang Hong-Ying Ye Ming Shen Xue-Fei Shou Zhi-Qiang Li Hong Peng Qing-Zhong Wang Dai-Zhan Zhou Xiao-Lan Qin Jue Ji Jie Zheng Hong Chen Yin Wang Dao-Ying Geng Wei-Jun Tang Chao-Wei Fu Zhi-Feng Shi Yi-Chao Zhang Zhao Ye Wen-Qiang He Qi-Lin Zhang Qi-Sheng Tang Rong Xie Jia-Wei Shen Zu-Jia Wen Juan Zhou Tao Wang Shan Huang Hui-Jia Qiu Ni-Dan Qiao Yi Zhang Li Pan Wei-Min Bao Ying-Chao Liu Chuan-Xin Huang Yong-Yong Shi Yao Zhao 2015Cell Research2015,25,3:16
20Determining method,conditional factors,traits and applications of nonlinear chemical fingerprint by using dissipative components in samples显示文摘The thermodynamic systems and dynamic model suitable for determining the nonlinear chemical fingerprints of samples were analyzed.The results indicated that the damp nonlinear chemical reactions in close systems away from the equilibrium and open systems without the complementarity of the dissipation substances have important significance for the throng characterization and whole content analysis of chemical components in samples.Various factors influencing on nonlinear chemical fingerprint,such as reactant species and their concentrations,electrode types,temperature,stir rate,the sort,dosage and granularity of the sample,etc.were amply researched by a nonlinear chemistry reaction,namely,damp B-Z oscillation which used acetone and glucose as the main dissipative substances.In addition,the quantitative information on the whole of chemical components in samples and the traits and applications of the fingerprint were investigated.The method and its important conditions for determining nonlinear chemistry fingerprint used in distinguishing and evaluating complex samples were successfully put forward.ZHANG TaiMing ZHAO Zhe FANG XuanQi QIAO JunXi XIANG FengQin ZHU Rong LIANG YiZeng DING Feng 2012Science China Chemistry2012,55,2:16
