| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Contrasting trends of PM2.5 and surface-ozone concentrations in China from 2013 to 2017显示文摘Although much attention has been paid to investigating and controlling air pollution in China,the trends of air-pollutant concentrations on a national scale have remained unclear.Here,we quantitatively investigated the variation of air pollutants in China using long-term comprehensive data sets from 2013 to 2017,during which Chinese government made major efforts to reduce anthropogenic emission in polluted regions.Our results show a significant decreasing trend in the PM2.5 concentration in heavily polluted regions of eastern China,with an annual decrease of〜7%compared with measurements in 2013.The measured decreased concentrations of SO2>NO2 and CO(a proxy for anthropogenic volatile organic compounds)could explain a large fraction of the decreased PM2.5 concentrations in different regions.As a consequence;the heavily polluted days decreased significantly in corresponding regions.Concentrations of organic aerosol;nitrate;sulfate,ammonium and chloride measured in urban Beijing revealed a remarkable reduction from 2013 to 2017;connecting the decreases in aerosol precursors with corresponding chemical components closely.However;surface-ozone concentrations showed increasing trends in most urban stations from 2013 to 2017;which indicates stronger photochemical pollution.The boundary-layer height in capital c让ies of eastern China showed no significant trends over the Beijing-Tianjin-Hebei,Yangtze River Delta and Pearl River Delta regions from 2013 to 2017;which confirmed the reduction in anthropogenic emissions.Our results demonstrated that the Chinese government was successful in the reduction of particulate matter in urban areas from 2013 to 2017,although the ozone concentration has increased significantly;suggesting a more complex mechanism of improving Chinese air quality in the future. | Yonghong Wang Wenkang Gao Shuai Wang Tao Song Zhengyu Gong Dongsheng Ji Lili Wang Zirui Liu Guiqian Tang Yanfeng Huo Shili Tian Jiayun Li Mingge Li Yuan Yang Biwu Chu Tuukka Petaja Veli-Matti Kerminen Hong He Jiming Hao Markku Kulmala Yuesi Wang Yuanhang Zhang | 2020 | National Science Review2020，7，8： | 51 |
| 3 | Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control. | Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu | 2021 | Science China(Life Sciences)2021，64，5： | 46 |
| 4 | Erianin,a novel dibenzyl compound in Dendrobium extract,inhibits lung cancer cell growth and migration via calcium/calmodulin-dependent ferroptosis显示文摘Ferroptosis,a novel form of programmed cell death,is characterized by iron-dependent lipid peroxidation and has been shown to be involved in multiple diseases,including cancer.Stimulating ferroptosis in cancer cells may be a potential strategy for cancer therapy.Therefore,ferroptosis-inducing drugs are attracting more attention for cancer treatment.Here,we showed that erianin,a natural product isolated from Dendrobium chrysotoxum Lindl,exerted its anticancer activity by inducing cell death and inhibiting cell migration in lung cancer cells.Subsequently,we demonstrated for the first time that erianin induced ferroptotic cell death in lung cancer cells,which was accompanied by ROS accumulation,lipid peroxidation,and GSH depletion.The ferroptosis inhibitors Fer-1 and Lip-1 but not Z-VAD-FMK,CQ,or necrostatin-1 rescued erianin-induced cell death,indicating that ferroptosis contributed to erianin-induced cell death.Furthermore,we demonstrated that Ca^(2+)/CaM signaling was a critical mediator of erianin-induced ferroptosis and that blockade of this signaling significantly rescued cell death induced by erianin treatment by suppressing ferroptosis.Taken together,our data suggest that the natural product erianin exerts its anticancer effects by inducing Ca^(2+)/CaMdependent ferroptosis and inhibiting cell migration,and erianin will hopefully serve as a prospective compound for lung cancer treatment. | Peng Chen Qibiao Wu Jiao Feng Lili Yan Yitian Sun Shuiping Liu Yu Xiang Mingming Zhang Ting Pan Xiaying Chen Ting Duan Lijuan Zhai Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Xuemeng Han Yicong Li Liuxi Chen Ying Liu Xingxing Huang Ting Jin Wenzheng Zhang Hong Luo Xiaohui Chen Yongqiang Li Qiujie Li Guohua Li Qin Zhang Lvjia Zhuo Zuyi Yang Huifen Tang Tian Xie Xiaoping Ouyang Xinbing Sui | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 42 |
| 5 | The abnormal expression of retinoic acid receptor-β,p53 and Ki67 protein,n normal,premalignant and malignant esophageal tissues显示文摘AIM: Esophageal cancer remains a significant healthiproblem worldwide. It is important to investigate alterationsin expression of retinoic acid receptor-β, p53 and Ki67proteins in esophageal carcinogenesis.METHODS: To find biomarkers for early identification ofesophageal cancer, we analyzed the retinoic acid receptor-j3,p53 protein and the proliferation marker Ki67 in surgicalspecimens of normal, mildly, and severely dysplastic andmalignant esophageal tissues by in situ hybridization ofRNA and immunohistochemistry.RESULTS: RAR-β was expressed in 94.3 %(33/35) of normalmucosae, 67.8 %(19/28) of the mild, 58.1% (18/31) of thesevere ieaions and 53.2 % (116/218) of tumor samples. RAR-β mRNA was expressed in 62.7 % (42/67), 55.1% (43/78) and29.2 % (7/24) of well, moderated and poorly differentiatedSSCs. The p53 and Ki67 proteins were 5.9 % (2/34) of thenormal mucosa. P53 and Ki67 stained positively in 10.7 % (3/28) and 21.4 % (6/28) of mild dysplasia, and 51.6 %(16/31)and 58. 1% (18/31) of severely dysplasia respectively.Samples from esophageal cancer showed no higher levers ofp53 and Ki67 expression than seen in severely dysplasticlesions. There was significant difference of RAR-β、 p53 andKi67 expression between normal mucosa and dysplatictissue or esophageal cancer.CONCLUSION: Loss of RAR-β expression and acctnulation ofp53 and Ki67 proteins may serve as biomarkers for earlyidentification of esophageal cancer in the high-riskpopulations. | Min Xu Sheng-Zu Chen,Department of Nuclear Medcine,Cancer Hospital(Institute),Peking Union Medical College and Chinese Academy of Medical Sciences,Beijing 10002,1,China Yu-Lan Jin Jun Fu Hong Huang Ping Qu Hai-Mei Tian ZhaoYang Liu Wei Zhang,Central Laboratory for Tumor Biology,Cancer Hospital(Institute),Peking Union Medical College and Chinese Academy of Medical Sciences,Beijing 100021,China | 2002 | World Journal of Gastroenterology2002，8，2： | 34 |

| 8 | ZIKA virus isolated from mosquitoes:a field and laboratory investigation in China,2016显示文摘A field investigation of arboviruses was conducted in Dejiang, Guizhou Province in the summer of 2016. A total of 8,795 mosquitoes, belonging to four species of three genera, and 1,300 midges were collected. The mosquito samples were identified on site according to their morphology, and the pooled samples were ground and centrifuged in the laboratory. The supernatant was incubated with mosquito tissue culture cells(C6/36) and mammalian cells(BHK-21) for virus isolation. The results indicated that 40%(3,540/8,795) were Anopheles sinensis, 30%(2,700/8,795) were Culex pipiens quinquefasciatus, and 29%(2,530/8,795)were Armigeres subbalbeatus. Furthermore, a total of eight virus isolates were obtained, and genome sequencing revealed two Zika viruses(ZIKVs) isolated from Culex pipiens quinquefasciatus and Armigeres subbalbeatus, respectively; three Japanese encephalitis viruses(JEVs) isolated from Culex pipiens quinquefasciatus; two Banna viruses(BAVs) isolated from Culex pipiens quinquefasciatus and Anopheles sinensis, respectively; and one densovirus(DNV) isolated from Culex pipiens quinquefasciatus.The ZIKVs isolated from the Culex pipiens quinquefasciatus and Armigeres subbalbeatus mosquitoes represent the first ZIKV isolates in China's Mainland. This discovery presents new challenges for the prevention and control of ZIKV in China, and prompts international cooperation on this global issue. | Shihong Fu Song Song Hong Liu Yuanyuan Li Xiaolong Li Xiaoyan Gao Ziqian Xu Guoping Liu Dingming Wang Zhenzao Tian Jingzhu Zhou Ying He Wenwen Lei Huanyu Wang Bin Wang Xiaoqing Lu Guodong Liang | 2017 | Science China(Life Sciences)2017，60，12： | 25 |

| 11 | Effects of magnolol and honokiol derived from traditional Chinese herbal remedies on gastrointestinal movement显示文摘AIM: To study the effects of magnolol and honokiol on isolated smooth muscle of gastrointestinal tract and their relationship with Ca2+, and on the gastric emptying and the intestinal propulsive activity in mice.METHODS: Routine experimental methods using isolated gastric fundus strips of rats and isolated ileum segments of guinea pigs were adopted to measure the smooth muscle tension. The effects of magnolol 10-3, 10-4, 10-5 mol/L, and honokiol 10-4, 10-5, 10-6 mol/L on the contractility of gastric fundus strips of rats and ileum of guinea pigs induced by acetylcholine (Ach) and 5-hydroxytryptamine (5-HT)was assessed respectively. The method using nuclein and pigment methylene blue was adopted to measure the gastric retention rate of nuclein and the intestinal propulsive ratio of a nutritional semi-solid meal for assessing the effect of magnolol and honokiol (0.5, 2, 20 mg/kg) on gastric emptying and intestinal propulsion.RESULTS: Magnolol and honokiol significantly inhibited the contractility of isolated gastric fundus strips of rats treated with Ach or 5-HT and isolated ileum guinea pigs treated with Ach or CaCl2, and both of them behaved as non-competitive muscarinic antagonists. Magnolol and honokiol inhibited the contraction induced by Ach in Ca2+-free medium and extracellular Ca2+-dependent contraction induced by Ach. Each group of magnolol and honokiol experiments significantly decreased the residual rate of nuclein in the stomach and increased the intestinal propulsive ratio in mice.CONCLUSION: The inhibitory effect of magnolol and honokiol on contractility of the smooth muscles of isolated gastric fundus strips of rats and isolated ileum of guinea pigs is associated with a calcium-antagonistic effect.Magnolol and honokiol can improve the gastric emptying of a semi-solid meal and intestinal propulsive activity in mice. | Wei-Wei Zhang Yan Li Xue-Qing Wang Feng Tian Hong Cao Min-Wei Wang Qi-Shi Sun | 2005 | World Journal of Gastroenterology2005，11，28： | 22 |
| 12 | A multi-center study of hemodynamic characteristics exhibited by children with unexplained syncope显示文摘Background Syncope is common in children and adolescents,with 15% estimated to have had at least one syncopal episode by age 18.In recent years,an increasing number of children,especially girls at their school age,have developed unexplained syncope.The mechanism of an unexplained syncope exhibited by children is incompletely studied;the association between different hemodynamic patterns and clinical features is also not clear.The aim of the study was to investigate the hemodynamic patterns of children with unexplained syncope and to examine the clinical relevance.Methods Two hundred and eight children [87 boys,121 girls,aged 3-19 years,mean(11.66±2.72) years] were selectively recruited from May 2000 to April 2006 when they presented syncope as their main complaint at the Multi-center Network for Childhood Syncope in Beijing,Hunan Province,Hubei Province,and Shanghai of China.All of the patients underwent head-up tilt tests;data were analyzed using SPSS version 10.0 for Windows.Continuous variables were expressed as the mean±standard deviation.Dichotomous variables were compared through a χ2 test.A value of P<0.05(two sided) was regarded as statistically significant.Results The age distribution of children with syncope was approximately normal.Head-up tilt tests was positive in 155 children,and the incidence of positive response of the baseline head-up tilt test for diagnosing unexplained syncope was 50.48%.The sensitivity value and diagnostic value of sublingual nitroglycerin head-up tilt test were both 74.52%.The hemodynamic pattern was normal in 53 children.The 155 children,who were positive in head-up tilt tests,showed signs of postural orthostatic tachycardia syndrome(60,28.8%),the vasoinhibitory pattern(72,34.6%),the cardioinhibitory pattern(5,2.4%),and the mixed pattern(18,8.7%).The gender distribution between the two age groups(age < 12 years vs age ≥ 12 years) was not different(P>0.05).The distribution of hemodynamic patterns between the children of the two age groups(age < 12 years vs age ≥ 12 years),and the children with different complaints(dizziness vs syncope) was significantly different(P<0.05),while the distribution between the children of different sexes and different lasting time of syncope(≤ 5 minutes vs> 5 minutes) was not significantly different(P>0.05).Different hemodynamic patterns were differentiated by differing syncope inducements,presymptoms,and complicated symptoms during and after syncope.Conclusion The tested girls were more prone when compared with the boys to have unexplained syncope,and the peak age was around twelve years old.The incidence of positive response of head-up tilt tests was also relatively higher for the girls.The distribution of hemodynamic patterns for different ages was different.For children with unexplained syncope,we should use head-up tilttests to distinguish the hemodynamic patterns in order to adopt rational therapeutic measures. | CHEN Li YANG Yuan-yuan WANG Cheng WANG Hong-wei TIAN Hong ZHANG Qing-you CHEN Jian-jun WANG Yu-li KANG Yi-long TANG Chao-shu DU Jun-bao | 2006 | Chinese Medical Journal2006，，24： | 23 |
| 13 | Temperature variation of a thermionic cathode during electron emission显示文摘It is necessary to know the actual temperature of a thermionic cathode that works as the electron source in a microwave tube. It has been found that the temperature of the cathode drops markedly during the thermionic emission. For example, the temperature could fall by about 30oC under a current density of 2.92 A/cm2. Using the molecular thermodynamics, the dependence of the cathode temperature on the emission current density has been obtained. It has been theoretically pointed out that several factors, such as heating model and temperature coefficient of resis-tance of heater, can influence the cathode temperature. These theoretical conclu-sions were supported by the experimental results. | LIU YanWen TIAN Hong HAN Yong XU ZhenYing MENG MingFeng ZHANG HongLai | 2008 | Science China(Technological Sciences)2008，51，9： | 22 |

| 15 | Matrix metalloproteinases contribute to kidney fibrosis in chronic kidney diseases显示文摘Matrix metalloproteinases(MMPs) are members of the neutral proteinase family. They were previously thought to be anti-fibrotic because of their ability to degrade and remodel of extracellular matrix. However, recent studies have shown that MMPs are implicated in initiation and progression of kidney fibrosis through tubular cell epithelial–mesenchymal transition(EMT) as well as activation of resident fibroblasts, endothelial-mesenchymal transition(Endo MT) and pericyte-myofibroblast transdifferentiation. Interstitial macrophage infiltration has also been shown to correlate with the severity of kidney fibrosis in various chronic kidney diseases. MMPs secreted by macrophages, especially MMP-9, hasbeen shown by us to be profibrotic by induction of tubular cells EMT. EMT is mainly induced by transforming growth factor-β(TGF-β). However, MMP-9 was found by us and others to be up-regulated by TGF-β1 in kidney tubular epithelial cells and secreted by activated macrophages, resulting in EMT and ultimately kidney fibrosis. Therefore, MMP-9 may serve as a potential therapeutic target to prevent kidney fibrosis in chronic kidney disease. This review, by a particular focus on EMT, seeks to provide a comprehensive understanding of MMPs, especially MMP-9, in kidney fibrosis. | Hong Zhao Yanting Dong Xinrui Tian Thian Kui Tan Zhuola Liu Ye Zhao Yun Zhang David CH Harris Guoping Zheng | 2013 | World Journal of Nephrology2013，2，3： | 21 |
| 16 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |

| 18 | Interaction of hepatitis C virus envelope glycoprotein E2 with the large extracellular loop of tupaia CD81显示文摘AIM: To further analyze the interaction of tupaia CD81 with hepatitis C virus (HCV) envelope protein E2. METHODS: A tupaia CD81 large extracellular loop (CD81 LEL), which binds to HCV E2 protein, was cloned and expressed as a GST-fusion protein, and interaction of HCV E2 protein with a tupaia CD81 LEL was evaluated by enzyme-linked immunosorbent assay (EIA). RESULTS: Although tupaia and human CD81 LEL differed in 6 amino acid changes, tupaia CD81 LEL was strongly recognized by anti-CD81 antibodies against human CD81 LEL conformation-dependent epitopes. Investigating LEL CD81-E2 interactions by EIA, we demonstrated that binding of tupaia CD81 LEL GST fusion protein to recombinant HCV E2 protein was markedly reduced compared to binding of human CD81 LEL GST fusion protein to recombinant HCV E2 protein. CONCLUSION: These data suggest that the structural differences in-between the tupaia and human CD81 may alter the interaction of the large extracellular loop with HCV envelope glycoprotein E2. These findings may be important for the understanding of the mechanisms of binding and entry of HCV to PTHs. | Zhan-Fei Tian Hong Shen Xi-Hua Fu Yi-Chun Chen Hubert E Blum Thomas F Baumert Xi-Ping Zhao | 2009 | World Journal of Gastroenterology2009，15，2： | 16 |
| 19 | Effects of long-term,low-dose sex hormone replacement therapy on hippocampus and cognition of postmenopausal women of different apoE genotypes显示文摘瞄准:学习效果长期,体积和在带 apolipoprotein E ( apoE )的绝经后的女人的马头鱼尾的怪兽的生物化学的变化上的低剂量的性荷尔蒙代替治疗( HRT )基因 epsilon 3 或 epsilon 4 .Methods :使用 HRT 的低剂量超过 4 年了的 83 个绝经后的女人作为 HRT 组被选择,并且当控制 group.ApoE 等位基因被 PCR.Magnetic 回声成像分析,有匹配的年龄和教育的 99postmenopausal 女人被注册被执行决定 brainhippocampus.Proton 的卷磁性的回声光谱学被用来在 apoE epsilon 在前面的 cingulate 外皮和马头鱼尾的怪兽检测生物化学的变化 4 并且 epsilon 3 个搬运人。六普通认知测试被用来做认知 function.Results 的全面评估: 有 4 个搬运人显示出的 apoE epsilon 的分析控制组的马头鱼尾的怪兽的卷是比 HRT 组的那些显著地低的。生物化学的分析证明有 N-acetylaspartate (NAA )/total 肌酸(tCr ) 和 myoinositol (mI ) 的减少的增加在在 HRT 的 4 个搬运人组织的 apoE epsilon 的马头鱼尾的怪兽的 /tCr,与控制组相比。为 apoEepsilon 3 个搬运人, HRT 组的最少的广场工具(LSMEAN ) 比控制 group.Conclusion 的高: 这研究证明长期的、低剂量 HRT 可能为在脆弱的绝经后的女人减少广告开发的风险是有益的。同时, HRT 能增加 apoE epsilon 的 LSMEAN 3 个搬运人。 | Yun YUE Ling HU Qin-jie TIAN Jing-mei JIANG Yi-long DONG Zheng-yu JIN yu-hang CHENG Xia HONG Qin-sheng GE Ping-ping ZUO | 2007 | Acta Pharmacologica Sinica2007，28，8： | 15 |
