2Timing of the Wudangshan, Yaolinghe volcanic sequences and mafic sills in South Qinling: U-Pb zircon geochronology and tectonic implication显示文摘The Wudangshan, Yaolinghe volcanic-sedimentary sequences and doleritic-gabbroic sills comprise the largest exposed Precambrian basement in South Qinling. Zircons separated from 5 volcanic-pyroclas- tic samples of the Wudangshan Group, 2 volcanic samples of the Yaolinghe Group and one sample for the mafic sills were used for U-Pb dating by laser ablation-inductively coupled plasma mass spec- trometry (LA-ICPMS). The results reveal that the Wudangshan volcanic sequence was formed at (755±3) Ma (a weighted mean from the 5 samples, MSWD=0.47), whereas the Yaolinghe volcanic suite and the mafic sill were crystallized at (685±5) (2 samples, MSWD=0.36) and (679±3) Ma (MSWD=1.6), respectively, which are equal to each other within analysis errors. These ages are markedly younger than those previously documented for the rocks. The newly obtained ages for the Wudangshan and Yaolinghe Groups are identical to those of the bottom Liantuo and slightly older than those of the Nantuo Forma- tions, respectively, lower strata of the Nanhua (middle to late Neoproterozoic) stratotype section in eastern Three Gorges, Yangtze craton. A range of inherited magmatic zircons was recognized with ages of 830 to 780 Ma, which are typical of Neoprotzrozoic magmatisms recorded along the margins and interior of the Yangtze craton. Thus, there is Neoproterozoic basement comprising 830―780 Ma igne- ous suites in South Qinling; the inherited zircons were detrital sediments derived from the northern margin of the Yangtze craton. Accordingly, it is suggested that the South Qinling is a segment of the Yangtze craton before the Qinling Orogeny.LING WenLi REN BangFang DUAN RuiChun LIU XiaoMing MAO XinWu PENG LianHong LIU ZaoXue CHENG JianPing YANG HongMei 2008Chinese Science Bulletin2008,53,14:44

4Visualization of the complex structure and stress field inside rock by means of 3D printing technology显示文摘Accurate characterization and visualization of the complex inner structure and stress distribution of rocks are of vital significance to solve a variety of underground engineering problems. In this paper, we incorporate several advanced technologies, such as CT scan, three-dimensional(3D) reconstruction, and 3D printing, to produce a physical model representing the natural coal rock that inherently contains complex fractures or joints. We employ 3D frozen stress and photoelastic technologies to characterize and visualize the stress distribution within the fractured rock under uniaxial compression. The 3D printed model presents the fracture structures identical to those of the natural prototype. The mechanical properties of the printed model,including uniaxial compression strength, elastic modulus,and Poisson's ratio, are testified to be similar to those of the prototype coal rock. The frozen stress and photoelastic tests show that the location of stress concentration and the stress gradient around the discontinuous fractures are in good agreement with the numerical predictions of the real coalsample. The proposed method appears to be capable of visually quantifying the influences of discontinuous,irregular fractures on the strength, deformation, and stress concentration of coal rock. The method of incorporating3 D printing and frozen stress technologies shows a promising way to quantify and visualize the complex fracture structures and their influences on 3D stress distribution of underground rocks, which can also be used to verify numerical simulations.Yang Ju Heping Xie Zemin Zheng Jinbo Lu Lingtao Mao Feng Gao Ruidong Peng 2014Chinese Science Bulletin2014,59,36:41
542,573 cases of hepatectomy in China: a multicenter retrospective investigation显示文摘Hepatectomy is currently routinely performed in most hospitals in China. China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma(HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients,81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein(AFP) level, and other 35% had an AFP level lower than 400 ng mL^(-1). In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was(191.7±105.6) min,the blood loss was(546.0±562.8) m L, and blood transfusion was(543.0±1,035.2) m L. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules,tumor thrombosis and high AFP level were risk factors that affect postoperative survival.Binhao Zhang Bixiang Zhang Zhiwei Zhang Zhiyong Huang Yifa Chen Minshan Chen Ping Bie Baogang Peng Liqun Wu Zhiming Wang Bo Li Jia Fan Lunxiu Qin Ping Chen Jingfeng Liu Zhe Tang Jun Niu Xinmin Yin Deyu Li Songqing He Bin Jiang Yilei Mao Weiping Zhou Xiaoping Chen 2018Science China(Life Sciences)2018,61,6:39
6Bile duct injuries associated with laparoscopic and open cholecystectomy: Sixteen-year experience显示文摘AIM: To summarize the experience in diagnosis, management and prevention of iatrogenic bile duct injury (IBDI). METHODS: A total of 210 patients with bile duct injury occurred during cholecystectomy admitted to Hunan Provincial People’s Hospital from March 1990 to March 2006 were included in this study for retrospective analysis. RESULTS: There were 59.5% (103/173) of patients with IBDI resulting from the wrong identification of the anatomy of the Calot’s triangle during cholecystectomy. The diagnosis of IBDI was made on the basis of clinical features, diagnostic abdominocentesis and imaging findings. Abdominal B ultrasonography (BUS) was the most popular way for IBDI with a diagnostic rate of 84.6% (126/149). Magnetic resonance cholangiography (MRC) could reveal the site of injury, the length of injured bile duct and variation of bile duct tree with a diagnostic rate 100% (45/45). According to the site of injury, IBDI could be divided into six types. The most common type (type 3) occurred in 76.7% (161/210) of the patients and was treated with partial resection of the common hepatic duct and common bile duct. One hundred and seventy-six patients were followed up. The mean follow-up time was 3.7 (range 0.25-10) years. Good results were achieved in 87.5% (154/176) of the patients. CONCLUSION: The key to prevention of IBDI is to follow the 'identifying-cutting-identifying' principle during cholecystectomy. Re-operation time and surgical procedure are decided according to the type of IBDI.Jin-Shu Wu Chuang Peng Xian-Hai Mao Pin Lv 2007World Journal of Gastroenterology2007,13,16:32
7Computation of fractal dimension of rock pores based on gray CT images显示文摘The characterization of pore structure in rocks is relevant in determining their various mechanical behaviors. Digital image processing methods integrated with fractal theory were applied to analyze images of rock slices obtained from industry CT, elucidating the characteristics of rock pore structure and the relationship between porosity and fractal dimensions. The gray values of pixels in CT images of rocks provide comprehensive results with respect to the attenuation coefficients of various materials in corresponding rock elements, and these values also reflect the effect of rock porosity at various scales. A segmentation threshold can be determined by inverse analysis based on the pore ratios that are measured experimentally, and subsequently binary images of rock pores can be obtained to study their topological structures. The fractal dimension of rock pore structure increases with an increase in rock pore ratio, and fractal dimensions might differ even if pore ratios are the same. The more complex the structure of a rock, the larger the fractal dimension becomes. The experimental studies have validated that fractal dimension calculated directly from gray CT images of rocks can give an effective complementary parameter to use alongside pore ratios and they can suitably represent the fractal characteristics of rock pores.PENG RuiDong YANG YanCong JU Yang MAO LingTao YANG YongMing 2011Chinese Science Bulletin2011,56,31:25
8U-Pb dating of detrital zircons from the Wudangshan Group in the South Qinling and its geological significance显示文摘U-Pb dating was made by the LA-ICP-MS method for detrital zircons from the Wudangshan volcanic-sedimentary succession in the South Qinling. Samples comprise quartz sandstones of the Wudangshan Group collected from the base of the Yangping For-mation and an upper layer of the Shuangtai Formation overlain its volcanic sequence, and two river-sand collections from the drainage systems cutting across the two formations, respectively. The results show that the Yangping detrital zircons are domi-nated by 830–780 Ma grains with a minor population of ~1.0–0.84 Ga and sporadic grains of ~2.6, ~2.4 and 2.0 Ga, whereas the Shuangtai zircons yield an upper intercept age of 763±33 Ma, identical to the timing of the Wudangshan volcanism within error, with few concordant grains of 1.9 and 0.86 Ga. Age spectra for the two river-sand samples are similar to those of the Yangping and Shuangtai Formations, respectively. It thus suggests that the Wudangshan strata are less than 780 Ma, whereas their major detrital zircon populations of 1.0–0.85 Ga and 830–780 Ma are consistent with timing of the Hannan magmatic activities along the northwestern margin of the South China Block. This suggests a Hannan or adjacent area provenance for the Wudangshan strata. The Wudang area is characterized by rift-related igneous events at ~755 and ~680 Ma, respectively, pointing to a tectono-magmatic history different from the Hannan area. It is inferred that the ~755 Ma magmatism is likely to indicate a separation of the South China Block from the supercontinent Rodinia, while the ~680 Ma event suggests a further split between the South Qinling and some unknown continent.LING WenLi DUAN RuiChun LIU XiaoMing CHENG JianPing MAO XinWu PENG LianHong LIU ZaoXue YANG HongMei REN BangFang 2010Chinese Science Bulletin2010,55,22:24
9Progresses on microwave remote sensing of land surface parameters显示文摘Highly accurate observations at various scales on the land surface are urgently needed for the studies of many areas,such as hydrology,meteorology,and agriculture.With the rapid development of remote sensing techniques,remote sensing has had the capacity of monitoring many factors of the Earth's land surface.Especially,the space-borne microwave remote sensing systems have been widely used in the quantitative monitoring of global snow,soil moisture,and vegetation parameters with their all-weather,all-time observation capabilities and their sensitivities to the characteristics of land surface factors.Based on the electromagnetic theories and microwave radiative transfer equations,researchers have achieved great successes in the microwave remote sensing studies for different sensors in recent years.This article has systematically reviewed the progresses on five research areas including microwave theoretical modeling,microwave inversion on soil moisture,snow,vegetation and land surface temperatures.Through the further enrichment of remote sensing datasets and the development of remote sensing theories and inversion techniques,remote sensing including microwave remote sensing will play a more important role in the studies and applications of the Earth systems.SHI JianCheng DU Yang DU JinYang JIANG LingMei CHAI LinNa MAO KeBiao XU Peng NI WenJian XIONG Chuan LIU Qiang LIU ChenZhou GUO Peng CUI Qian LI YunQing CHEN Jing WANG AnQi LUO HeJia WANG YinHui 2012Science China Earth Sciences2012,55,7:24
10Arbuscular Mycorrhizal Fungal Inoculation Enhances Suppression of Cucumber Fusarium Wilt in Greenhouse Soils显示文摘A pot experiment was conducted to study the plant growth and fruit yields of cucumber (Cucumis sativus L.) on a greenhouse soil with or without inoculation of arbuscular mycorrhizal fungi (AMFs) and Fusarium oxysporum f. sp. cucu- merinum under unsterilized conditions. Two AMF inocula were tested: only one AMF strain Glomus caledonium 90036 and an AMF consortium mainly consisting of Glomus spp. and Acaulospora spp. There were four treatments including no inoculation (control), inoculation with F. oxysporum but without mycorrhizae (FO), inoculation with F. oxysporum and G. caledonium (FO+M1), and inoculation with F. oxysporum and the AMF consortium (FO+M2). Cucumber plants were harvested at weeks 3 and 9 after transplanting. Compared with the control, the FO treatment without AMF inoculation had less biomass both at weeks 3 and 9 (P < 0.05) and had higher incidence of Fusarium wilt and produced no cucumber fruit at week 9. Both FO+M1 and FO+M2 treatments had higher mycorrhizal colonization than the treatments which received no AMF inoculation at week 3 (P < 0.05), but only the FO+M2 treatment elevated plant biomass, decreased the incidence of Fusarium wilt, and improved cucumber yields to the same level as the control at week 9. The results indicated that the AMF consortium could suppress Fusarium wilt of cucumber and, therefore, showed potential as a biological control agent in greenhouse agroecosystems.HU Jun-Li LIN Xian-Gui WANG Jun-Hua SHEN Wei-Shou WU Shu PENG Su-Ping MAO Ting-Ting 2010Pedosphere2010,20,5:23

14On-line chatter detection using servo motor current signal in turning显示文摘Chatter often poses limiting factors on the achievable productivity and is very harmful to machining processes. In order to avoid effectively the harm of cutting chatter,a method of cutting state monitoring based on feed motor current signal is proposed for chatter identification before it has been fully developed. A new data analysis technique,the empirical mode decomposition(EMD),is used to decompose motor current signal into many intrinsic mode functions(IMF) . Some IMF's energy and kurtosis regularly change during the development of the chatter. These IMFs can reflect subtle mutations in current signal. Therefore,the energy index and kurtosis index are used for chatter detection based on those IMFs. Acceleration signal of tool as reference is used to compare with the results from current signal. A support vector machine(SVM) is designed for pattern classification based on the feature vector constituted by energy index and kurtosis index. The intelligent chatter detection system composed of the feature extraction and the SVM has an accuracy rate of above 95% for the identification of cutting state after being trained by experimental data. The results show that it is feasible to monitor and predict the emergence of chatter behavior in machining by using motor current signal.LIU HongQil CHEN QmgHa LI Bin MAO XinYong MAO KuanMin PENG FangYu 2011Science China(Technological Sciences)2011,54,12:15
15Significant value of 18F-FDG-PET/CT in diagnosing small cervical lymph node metastases in patients with nasopharyngeal carcinoma treated with intensity-modulated radiotherapy显示文摘Background: Little is known about the nature of metaistasis to small cervical lymph nodes(SCLNS) in the patients with nasopharyngeal carcinoma(NPC)examined by using 18-fluoro-2-deoxy-glucose(^(18)F-FDG) positron emission tomography/computed tomography(PET/CT).The present study aimed to evaluate the diagnostic values of PET/CT in identifying metastasis in SCLNs in NPC patients.Methods: Magnetic resonance images(MRI) and PET/CT scans for 470 patients with newly diagnosed, non-distant metastatic NPC were analyzed. Metastatic rates of SCLNs were defined by the positive number of SCLNs on PET/CT scans and total number of SCLNs on MRI scans. Receiver operating characteristic curve was applied to compare PET/CT-determined stage with MRI-determined stage.Results: In total, 2082 SCLNs were identified, with 808(38.8%) ≥ 5 and < 6 mm in diameter(group A), 526(25.3%)≥ 6 and < 7 mm in diameter(group B),374(18.0%)≥ 7 and < 8 mm in diameter(group C), 237(11.4%) ≥8 and<9 mm in diameter(group D),and 137(6.5%) ≥ 9 and <10 mm in diameter(group E).The overall metastatic rates examined by using PET/CT for groups A, B,C,D, and E were 3.5%, 8.0%, 31.3%, 60.0%, and 83.9%, respectively(P< 0.001). In level IV/Vb, the metastatic rate for nodes ≥ 8 mm was 84.6%. PET/CT examination resulted in modification of N category and overall stage for 135(28.7%) and 46(9.8%) patients, respectively. The areas under curve of MRIdetermined and PET/CT-determined overall stage were 0.659 and 0.704 for predicting overall survival, 0.661 and 0.711 for predicting distant metastasis-free survival, and 0.636 and 0.663 for predicting disease-free survival.Conclusions: PET/CT was more effective than MRI in identifying metastatic SCLNs, and the radiologic diagnostic criteria for metastatic lymph nodes in level IV/Vb should be re-defined.Hao Peng Lei Chen Ling-Long Tang Wen-Fei Li Yan-Ping Mao Rui Guo Yuan Zhang Li-Zhi Liu Li Tian Xu Zhang Xiao-Ping Lin Ying Guo Ying Sun Jun Ma 2017Chinese Journal of Cancer2017,36,12:14
16Altered oral microbiota in chronic hepatitis B patients with different tongue coatings显示文摘AIM To elucidate tongue coating microbiota and metabolic differences in chronic hepatitis B(CHB) patients with yellow or white tongue coatings.METHODS Tongue coating samples were collected from 53 CHBpatients(28 CHB yellow tongue coating patients and 25 CHB white tongue coating patients) and 22 healthy controls.Microbial DNA was extracted from the tongue samples,and the bacterial 16 S ribosomal RNA gene V3 region was amplified from all samples and sequenced with the Ion Torrent PGM^(TM)sequencing platform according to the standard protocols.The metabolites in the tongue coatings were evaluated using a liquid chromatographymass spectrometry(LC-MS) platform.Statistical analyses were then performed.RESULTS The relative compositions of the tongue coating microbiotas and metabolites in the CHB patients were significantly different from those of the healthy controls,but the tongue coating microbiota abundances and diversity levels were not significantly different.Compared with the CHB white tongue coating patients,the CHB yellow tongue coating patients had higher hepatitis B viral DNA(HBV-DNA) titers(median 21210 vs 500,respectively,P = 0.03) and a significantly lower level of Bacteroidetes(20.14% vs 27.93%,respectively,P = 0.013) and higher level of Proteobacteria(25.99% vs 18.17%,respectively,P = 0.045) in the microbial compositions at the phylum level.The inferred metagenomic pathways enriched in the CHB yellow tongue coating patients were mainly those involved in amino acid metabolism,which was consistent with the metabolic disorder.The abundances of bacteria from Bacteroidales at the order level were higher in the CHB white tongue coating patients(19.2% vs 27.22%,respectively,P = 0.011),whereas Neisseriales were enriched in the yellow tongue coating patients(21.85% vs 13.83%,respectively,P = 0.029).At the family level,the abundance of Neisseriaceae in the yellow tongue patients was positively correlated with the HBV-DNA level but negatively correlated with the S-adenosyl-L-methionine level.CONCLUSION This research illustrates specific clinical features and bacterial structures in CHB patients with different tongue coatings,which facilitates understanding of the traditional tongue diagnosis.Yu Zhao Yu-Feng Mao Yi-Shuang Tang Ming-Zhu Ni Qiao-Hong Liu Yan Wang Qin Feng Jing-Hua Peng Yi-Yang Hu 2018World Journal of Gastroenterology2018,24,30:13
17Relationship between β-amyloid protein 1-42, thyroid hormone levels and the risk of cognitive impairment after ischemic stroke显示文摘BACKGROUND Post-stroke cognitive impairment(PSCI)is not only a common consequence of stroke but also an important factor for adverse prognosis of patients.Biochemical indicators such as blood lipids and blood pressure are affected by many factors,and the ability of evaluating the progress of patients with PSCI is insufficient.Therefore,it is necessary to find sensitive markers for predicting the progress of patients and avoiding PSCI.Recent studies have shown thatβ-amyloid protein 1-42(Aβ1-42)and thyroid hormone levels are closely related to PSCI,which may be the influencing factors of PSCI,but there are few related studies.AIM To investigate the relationship between serum levels of Aβand thyroid hormones in acute stage and PSCI and its predicted value.METHODS A total of 195 patients with acute cerebral infarction confirmed from June 2016 to January 2018 were enrolled in this study.Baseline data and serological indicators were recorded to assess cognitive function of patients.All patients were followed up for 1 year.Their cognitive functions were evaluated within 1 wk,3 mo,6 mo and 1 yr after stroke.At the end of follow-up,the patients were divided into PSCI and non-PSCI according to Montreal cognitive assessment score,and the relationship between biochemical indexes and the progression of PSCI was explored.RESULTS Compared with patients with non-PSCI,the levels of Aβ1-42,triiodothyronine(T3)and free thyroxin were lower in the patients with PSCI.Repeated measures analysis of variance showed that the overall content of Aβ1-42 and T3 in PSCI was also lower than that of the non-PSCI patients.Further analysis revealed that Aβ1-42(r=0.348),T3(r=0.273)and free thyroxin(r=0.214)were positively correlated with disease progression(P<0.05),suggesting that these indicators have the potential to predict disease progression and outcome.Cox regression analysis showed that Aβ1-42 and T3 were important factors of PSCI.Then stratified analysis showed that the lower the Aβ1-42 and T3,the higher risk of PSCI in patients who were aged over 70,female and illiterate.CONCLUSION Aβ1-42 and T3 have the ability to predict the progression of PSCI,which is expected to be applied clinically to reduce the incidence of PSCI and improve the quality of life of patients.Lei Mao Xiao-Han Chen Jian-Hua Zhuang Peng Li Yi-Xin Xu Yu-Chen Zhao Yue-Jin Ma Bin He You Yin 2020World Journal of Clinical Cases2020,8,1:13

20Activity of the Lenglongling fault system and seismotectonics of the 2016 MS6.4 Menyuan earthquake显示文摘The MS6.4 Menyuan earthquake occurred on the northern side of the Lenglongling fault(LLLF) in the mid-western of the Qilian-Haiyuan fault zone on January 21, 2016. The earthquake epicenter was distant from the Minle-Damaying and Huangcheng-Shuangta faults, eastern of the Northern Qilian Shan fault zone. A near northwest-striking rupture plane intersects the two faults at a certain angle. The focal mechanism solution shows that this was a thrust-type earthquake, slightly different from the strike-slip movement with a thrust component of the LLLF. Field geological mapping, tectonic geomorphology analysis, trench excavation and 14 C dating reveal that(1) the LLLF has been obviously active since the Holocene, and may behave with characteristic slip behavior and produce M_W7.3–7.5 earthquakes;(2) the LLLF appears as a flower structure in terms of structure style, and dips NNE at a steep angle; and(3) the most recent earthquake event occurred after 1815–1065 a BP. An associated fault, the Northern Lenglongling fault(NLLLF), is located at the northwestern end of the LLLF. Consequently, the NLLLF was continually subject to tectonic pushing effects from the left-lateral shear at the end of the LLLF, and, accordingly, it bent and rotated outward tectonically.Subsequently, the fault deviated from the dominant rupture azimuth and activity weakened. In the late Quaternary, it behaved as a thrust fault with no obvious deformation at the surface. This is indicated by the arc shape, with a micro-protrusion northeastward,and no geologic or geomorphic signs of surface rupturing since the late Quaternary. However, such faults could still rupture at depth, producing moderate-strong earthquakes. The geometric and kinematic properties of the NLLLF are in good agreement with the occurrence and kinematic properties of nodal plane 2, and with the distribution characteristics of the aftershocks and seismic intensity. Therefore, the NLLLF is a more suitable seismogenic structure for the MS 6.4 Menyuan earthquake. In addition, the thrust movement of the NLLLF accommodates subsequent movement of the LLLF. During the historical evolution of the NLLLF,the LLLF and the NLLLF have affected the local topography through tectonic uplift.GUO Peng HAN ZhuJun AN YanFen JIANG WenLiang MAO ZeBin FENG Wei 2017Science China Earth Sciences2017,60,5:13
