1Resistance of Helicobacter pylori to antibiotics from 2000 to 2009 in Shanghai显示文摘AIM: To investigate the resistance of Helicobacter pylori (H. pylori ) to 6 commonly used antibiotics from 2000 to 2009 in Shanghai. METHODS: A total of 293 H. pylori strains were collected from 2000 to 2009 in Shanghai and tested for their susceptibility to metronidazole, clarithromycin, amoxicillin, furazolidone, levofloxacin and tetracycline using agar dilution. RESULTS: The resistant rates of H. pylori to clarithromycin (8.6%, 9.0% and 20.7%) and levofloxacin (10.3%, 24.0% and 32.5%) increased from 2000 to 2009 in Shanghai. The resistant rate of H. pylori to metronidazole remained stable (40%-50%). Only one strain of H. pylori isolated in 2005 was resistant to tetracycline. All strains were sensitive to amoxicillin and furazolidone.The resistant rate of H. pylori to antibiotics was not related with the sex, age and clinical outcome of patients. CONCLUSION: Resistance of H. pylori to antibiotics plays an important role in making treatment strategies against H. pylori -associated diseases.Qin-Juan Sun Xiao Liang Qing Zheng Wei-Qi Gu WenZhong Liu Shu-Dong Xiao Hong Lu 2010World Journal of Gastroenterology2010,16,40:90
2Changing patterns of colorectal cancer in China over a period of 20 years显示文摘AIM: To determine whether any changes have occurred on the patterns of colorectal cancer in China.METHODS: Data from 21 Chinese articles published from 1980 to 1999, were used to analyze the time trend of colorectal cancer according to the patients' age at diagnosis,sex, the site of the tumor, stage, and the pathology.RESULTS: From 1980s to 1990s, the mean age of the colorectal cancer patients has increased. The percentage of the female patients rose. The distribution of colorectal carcinoma shows a predominance of rectal cancer. However,the proportion of proximal colon cancer (including transverse and ascending colon) increased significantly accompanied by a decline in the percentage of rectal cancer. Similarity in the percentage of distal colon cancer between two decades was revealed. In the 1990s, statistically more Stage B patients were found than those in 1980s. In addition, databases show a significant decrease in the Stage D cases. The proportion of adenocarcinoma increased, but the mucinous adenocarcinoma decreased during two decades.CONCLUSION: These findings indicate that the patternof colorectal cancer in China has been changing. Especially,a proximal shift due to the increasing proportion of ascending and transverse colon cancer has occurred in China.Ming Li Jin Gu 2005World Journal of Gastroenterology2005,11,30:93
3The zircon SHRIMP chronology and trace elementgeochemistry of the Carboniferous volcanic rocksin western Tianshan Mountains显示文摘The genesis of the Carboniferous volcanic rocks in the Dahalajunshan group, mainly consisting of trachytes and trachy-andesites and distributing widely in western Tianshan Mountains, remains to be controversial. It has been proposed to be relevant to “rift” or “plume”. Detailed pe-trology and geochemical data presented in this paper show that these volcanic rocks represent typical continental arc magmatism. The volcanic rocks are mainly trachy-andesitic, and the magma source is enriched in LILE, Th and Pb, and depleted in HFSE and Ce. Trace element geochemical study suggests that the basalts could be modeled by 7%-11% partial melt of garnet lherzolite. The volcanic rocks in the Dahala-junshan group are neither the products of “rift” nor so-called “plume” but represent the continental island arc of the Pa-leo-Southern Tianshan Ocean. The mantle wedge had been modified by the melt generating in subduction zone during a long evolution history of this island arc. The continental crust materials (i.e. mainly sediment on ocean floor) had been added into island arc through melt in subduction zone. Volcanic rocks occurring in different regions might represent magma eruption in different time. The zircon SHRIMP dat-ing indicates that the ages of the basalt varies between 334.0 Ma and 394.9 Ma. The 13 analyses give an average age of 353.7 ±4.5 Ma (MSWD = 1.7). The apparent ages of zircons in trachy-andesite vary between 293.0 Ma and 465.4 Ma. All analyses fall on the U-Pb concordant line and are divided into two groups. 8 analyses produce an average age of 312.8±4.2 Ma (MSWD = 1.7), which represents the crystal-lizing age of zircon rims in trachy-andesite. The acquired two ages (i.e. 354 and 313 Ma) belong to the Early Carboniferous and Late Carboniferous epochs, respectively. Thus, the Da-halajunshan group would be separated into several groups with the accumulation of high-quality age dating and data of trace element and isotopic geochemistry, in our opinion.ZHU Yongfeng ZHANG Lifei GU Libing GUO Xuan ZHOU Jing 2005Chinese Science Bulletin2005,50,19:188

5大型浅水湖泊沉积物内源营养盐释放模式及其估算方法——以太湖为例显示文摘在新的野外调查和室内试验基础上,完善了有关大型浅水湖泊沉积物内源营养盐释放的模式,并在此基础上提出了太湖内源释放的估算方法。通过在太湖开展室内释放模拟实验和风浪期间底泥悬浮及上覆水中营养盐浓度变化的野外观测,提出了静态与动态二种浅水湖泊内源释放模式。静态情况下,营养盐主要通过浓度梯度扩散从沉积物进入上覆水,其释放强度受控于沉积物~水界面的温度,氧化还原环境及营养盐浓度差;动态条件下,沉积物由于动力扰动而发生悬浮,沉积物中溶解性及颗粒态的营养盐随着沉积物的悬浮而释放。虽然动态情况下总的营养盐释放较静态条件下大,但由于湍流导致水体及水土界面充氧,铁,锰等金属元素因氧化而吸附溶解性营养盐(特别是活性磷SRP)的能力增强,所以动力扰动仅引起总的营养盐释放,而不一定导致溶解性营养盐的释放。因此,在动态条件下,营养盐总释放量受控于动力扰动强度,底泥可悬浮量及沉积物中的营养盐含量;对于可溶性的营养盐,特别是SRP,其释放还受控于动力复氧的强度,沉积物中铁的含量及沉积物间隙水与上覆水中营养盐的浓度差。在此基础上,分别估算了静态和动态二种情况下沉积物内源释放量。根据实验室模拟结果,静态条件下太湖全湖一年NH_4^+-N释放量达1万吨左右,PO_4^(3-)-P释放量达900 t左右;结合太湖2001年的风场观测记录,把太湖野外风浪过程分为风平浪静,小风浪,大风浪三种情况,分别占全年总日数的12%,82%,6%在“风平浪静”条件下,其释放量根据实验室的静态释放试验来估算,而“小风浪”和“大风浪”条件下,其释放量则根据室内水槽试验得到的释放通量来估算。结果显示太湖全年释放量为总氮8.1万吨,总磷为2.1万吨;分别为外源氮磷年输入量的2-6倍。秦伯强 朱广伟 张路 罗潋葱 高光 Gu Binghe 2005中国科学:地球科学2005,39,S2:113

11Clinical observation of salvianolic acid B in treatment of liver fibrosis in chronic hepatitis B显示文摘AIM: To evaluate the clinical efficacy of salvianolic acidB (SA-B) on liver fibrosis in chronic hepatitis B.METHODS: Sixty patients with definite diagnosis of liverfibrosis with hepatitis B were included in the trial.Interferon-γ (IFN-γ) was used as control drug. Thepatients took orally SA-B tablets or received muscularinjection of IFN-γ in the double blind randomized test,The complete course lasted 6 months. The histologicalchanges of liver biopsy specimen before and after thetreatment were the main evidence in evaluation, incombination with the results of contents of serum HA,LN, Ⅳ-C, P-Ⅲ-P, liver ultrasound imaging, andsymptoms and signs.RESULTS: Reverse rate of fibrotic stage was 36.67 % inSA-B group and 30.0 % in IFN-γgroup. Inflammatoryalleviating rate was 40.0 % in SA-B group and 36.67 %in IFN-γ group. The average content of HA and Ⅳ-Cwas significantly lower than that before treatment. Theabnormal rate also decreased remarkably. Overallanalysis of 4 serological fibrotic markers showedsignificant improvement in SA-B group as comparedwith the IFN-γgroup. Score of liver ultrasound imagingwas lower in SA-B group than in IFN-γgroup (HA 36.7 %vs80 %,Ⅳ-C 3.3 % vs23.2 %). Before the treatment,ALT AST activity and total bilirubin content of patientswho had regression of fibrosis after oral administrationof SA-B, were significantly lower than those of patientswho had aggravation of fibrosis after oraladministration of SA-B. IFN-γ showed certain sideeffects (fever and transient decrease of leukocytes,occurrence rates were 50 % and 3.23 %), but SA-Bshowed no side effects.CONCLUSION: SA-B could effectively reverse liverfibrosis in chronic hepatitis B. SA-B was better than IFN-γ in reduction of serum HA content, overall decrease of4 serum fibrotic markers, and decrease of ultrasoundimaging score. Liver fibrosis in chronic hepatitis B withslight liver injury was more suitable to SA-B in anti-fibrotic treatment. SA-B showed no obvious side effects.Ping Liu Yi-Yang Hu Cheng Liu Hui-Ming Xue Zhi-Qiang Xu Lie-Ming Xu Cheng-Hai Liu Hong-Tu Gu Shanghai University of Traditional Chinese Medicine,Shanghai 200032,China Da-Yuan Zhu Shanghai Institute of Metaria Medica,Chinese Academy of Sciences,Shanghai 200031,China Zhi-Qing Zhang the 4~(th) Hualyin City Hospital,Hualan City,223000,JiangSu Province,China 2002World Journal of Gastroenterology2002,8,4:85
12Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang 2020Chinese Medical Journal2020,,9:99
13China Stroke Statistics 2019:A Report From the National Center for Healthcare Quality Management in Neurological Diseases,China National Clinical Research Center for Neurological Diseases,the Chinese Stroke Association,National Center for Chronic and Non-communicable Disease Control and Prevention,Chinese Center for Disease Control and Prevention and Institute for Global Neuroscience and Stroke Collaborations显示文摘China faces the greatest challenge from stroke in the world.The death rate for cerebrovascular diseases in China was 149.49 per 100000,accounting for 1.57 million deaths in 2018.It ranked third among the leading causes of death behind malignant tumours and heart disease.The age-standardised prevalence and incidence of stroke in 2013 were 1114.8 per 100000 population and 246.8 per 100000 person-years,respectively.According to the Global Burden of Disease Study 2017,the years of life lost(YLLs)per 100000 population for stroke increased by 14.6%;YLLs due to stroke rose from third highest among all causes in 1990 to the highest in 2017.The absolute numbers and rates per 100000 population for all-age disability-adjusted life years(DALYs)for stroke increased substantially between 1990 and 2017,and stroke was the leading cause of all-age DALYs in 2017.The main contributors to cerebrovascular diseases include behavioural risk factors(smoking and alcohol use)and pre-existing conditions(hypertension,diabetes mellitus,dyslipidaemia and atrial fibrillation(AF)).The most prevalent risk factors among stroke survivors were hypertension(63.0%-84.2%)and smoking(31.7%-47.6%).The least prevalent was AF(2.7%-7.4%).The prevalences for major risk factors for stroke are high and most have increased over time.Based on the latest national epidemiological data,26.6%of adults aged≥15 years(307.6 million adults)smoked tobacco products.For those aged≥18 years,age-adjusted prevalence of hypertension was 25.2%;adjusted prevalence of hypercholesterolaemia was 5.8%;and the standardised prevalence of diabetes was 10.9%.For those aged≥40 years,the standardised prevalence of AF was 2.31%.Data from the Hospital Quality Monitoring System showed that 3010204 inpatients with stroke were admitted to 1853 tertiary care hospitals during 2018.Of those,2466785(81.9%)were ischaemic strokes(ISs);447609(14.9%)were intracerebral haemorrhages(ICHs);and 95810(3.2%)were subarachnoid haemorrhages(SAHs).The average age of patients admitted was 66 years old,and nearly 60%were male.A total of 1555(0.1%),2774(0.6%)and 1347(1.4%)paediatric strokes(age<18 years)were identified among IS,ICH and SAH,respectively.Over one-third(1063892(35.3%))of the patients were covered by urban resident basic medical insurance,followed by urban employee basic medical insurance(699513(23.2%))and new rural cooperative medical schema(489361(16.3%)).The leading risk factor was hypertension(67.4%for IS,77.2%for ICH and 49.1%for SAH),and the leading comorbidity was pneumonia or pulmonary infection(10.1%for IS,31.4%for ICH and 25.2%for SAH).In-hospital death/discharge against medical advice rate was 8.3%for stroke inpatients,ranging from 5.8%for IS to 19.5%for ICH.The median and IQR of length of stay was 10.0(7.0-14.0)days,ranging from 10.0(7.0-13.0)in IS to 14.0(8.0-22.0)in SAH.Data from the Chinese Stroke Center Alliance demonstrated that the composite scores of guideline-recommended key performance indicators for patients with IS,ICH and SAH were 0.77±0.21,0.72±0.28 and 0.59±0.32,respectively.Yong-Jun Wang Zi-Xiao Li Hong-Qiu Gu Yi Zhai Yong Jiang Xing-Quan Zhao Yi-Long Wang Xin Yang Chun-Juan Wang Xia Meng Hao Li Li-Ping Liu Jing Jing Jing Wu An-Ding Xu Qiang Dong David Wang Ji-Zong Zhao On behalf of China Stroke Statistics 2019 Writing Committee 2020Stroke & Vascular Neurology2020,5,3:181

17Zircon SHRIMP Dating for the Weiya Pluton, Eastern Tianshan: Its Geological Implications显示文摘The timing of the emplacement of the Weiya pluton remains controversial due to the absence of systematic and precise dating. This paper reports zircon SHRIMP U-Pb dating of different lithologic phases in the Weiya pluton, and discusses the genesis and tectonic environment. The ages of gabbro, quartz syenite, diorite porphyrite and fine-grained granite are 236?6 Ma, 246?6 Ma, 233?8 Ma and 237?8 Ma, respectively. All these phases were formed in early-middle Indosinian (Triassic) in a post-orogenic environment. In addition to underplating, intraplating of mantle-derived magmas is also a substantial mechanism for magma generation and vertical accretion of the continental crust. Granitoid rocks are important products of vertical continental accretion as underplating evolves gradually to intraplating. The existence of post-orogenic Indosinian granites shows that the middle Tianshan orogenic belt underwent an important tectonic conversion from the Paleo-Asian ocean subduction-collision system to the Paleo-Tethys ocean regime.ZHANG Zunzhong GU Lianxing WU Changzhi LI Weiqiang XI Aihua WANG Shuo 2005Acta Geologica Sinica(English Edition)2005,79,4:53
