3Research on the slope spectrum of the Loess Plateau显示文摘A new concept dealing with digital analysis of loess terrain,slope spectrum,is presented and discussed in this paper,by introducing its characteristic,represen-tation and extracting method from DEMs. Using 48 geomorphological units in dif-ferent parts of the loess as test areas and 5 m-resolution DEMs as original test data,the quantitative depiction and spatial distribution of slope spectrum in China's Loess Plateau have been studied on the basis of a series of carefully-designed experiments. In addition,initial experiment indicates a strong relationship between the slope spectrum and the loess landform types,displaying a potential importance of the slope spectrum in geomorphological studies. Based on the slope spectrums derived from the 25 m-resolution DEM data in whole loess terrain in northern part of Shaanxi,13 slope spectrum indices were extracted and integrated into a compre-hensive layer with image integration method. Based on that,a series of unsuper-vised classifications was applied in order to make a landform classification in northern Shaanxi Loess Plateau. Experimental results show that the slope spec-trum analysis is an effective method in revealing the macro landform features. A continuous change of slope spectrum from south to north in northern Shaanxi Loess Plateau shows an obvious spatial distribution of different loess landforms. This also proves the great significance of the slope spectrum method in describing the terrain roughness and landform evolution as well as a further understanding on landform genesis and spatial distribution rule of different landforms in the Loess Plateau.TANG GuoAn,LI FaYuan,LIU XueJun,LONG Yi & YANG Xin Key Laboratory of Virtual Geographic Environment,Nanjing Normal University,Ministry of Education,Nanjing 210046,China 2008Science China(Technological Sciences)2008,51,S1:22
4Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure显示文摘AIM:To study the clinical efficacy of traditional Chinese medicine(TCM)intervention'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')for treating liver failure due to chronic hepatitis B.METHODS:We designed the study as a randomized controlled clinical trial.Registration number of Chinese Clinical Trial Registry is Chi CTR-TRC-12002961.A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study.Participants were randomly assigned to the following three groups:(1)a modern medicine control group(MMC group,36patients);(2)a'tonifying qi and detoxification'('TQD')group(72 patients);and(3)a'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')group(36patients).Patients in the MMC group received general internal medicine treatment;patients in the'TQD'group were given a TCM formula'tonifying qi and detoxification'and general internal medicine treatment;patients in the'TTK'group were given a TCM formula of'TTK'and general internal medicine treatment.All participants were treated for 8 wk and then followed at 48 wk following their final treatment.The primaryefficacy end point was the patient fatality rate in each group.Measurements of various virological and biochemical indicators served as secondary endpoints.The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups.RESULTS:At the 48-wk post-treatment time point,the patient fatality rates in the MMC,'TQD',and'TTK'groups were 51.61%,35.38%,and 16.67%,respectively,and the differences between groups were statistically significant(P<0.05).However,there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups(P>0.05).Patients in the'TTK'group had significantly higher levels of serum total bilirubin compared to MMC subjects(339.40μmol/L±270.09μmol/L vs 176.13μmol/L±185.70μmol/L,P=0.014).Serum albumin levels were significantly increased in both the'TQD'group and'TTK'group as compared with the MMC group(31.30 g/L±4.77g/L,30.72 g/L±2.89 g/L vs 28.57 g/L±4.56 g/L,P<0.05).There were no significant differences in levels of alanine transaminase among the three groups(P>0.05).Safety data showed that there was one case of stomachache in the'TQD'group and one case of gastrointestinal side effect in the'TTK'group.CONCLUSION:Treatment with'TTK'improved the survival rates of patients with liver failure due to chronic hepatitis B.Additionally,liver tissue was regenerated and liver function was restored.Han-Min Li Zhi-Hua Ye Jun Zhang Xiang Gao Yan-Ming Chen Xin Yao Jian-Xun Gu Lei Zhan Yang Ji Jian-Liang Xu Ying-He Zeng Fan Yang Lin Xiao Guo-Guang Sheng Wei Xin Qi Long Qing-Jing Zhu Zhao-Hong Shi Lian-Guo Ruan Jia-Yao Yang Chang-Chun Li Hong-Bin Wu Sheng-Duo Chen Xin-La Luo 2014World Journal of Gastroenterology2014,20,48:20
5A review of removal technology for antimony in aqueous solution显示文摘Antimony(Sb)and its compounds,toxic metalloid,have been classified as high-priority pollutants.Increasing Sb released into the water environment by natural processes and anthropogenic activities,which exposure threatens to human health and ecosystems.Therefore,it is of unquestionable importance to remove Sb from polluted water.Keeping in view the extreme importance of this issue,we summarize the source,chemistry,speciation,distribution,toxicity,and polluted situation of Sb about aqueous solution.Then,we provide the recent and common technology to remove Sb,which are based on adsorption,coagulation/flocculation,electrochemical technology,membrane technology,ion exchange,etc.In this review,we focus in detail on the adsorption method,researchers at present have been investigating to discover more advanced,cost-effective,eco-friendly,reusable adsorbents.However,to date the Sb-containing wastewater treatment technologies are not sufficiently developed and most of research have been tested only in controlled lab conditions.Few reports are available that include field studies and applications.We critically analyzed the salient features and removal mechanisms,evaluating benefits and limitations of these technologies,hoping to provide more references for further research.Finally,we considered the Fe-or Mn-based technologies was the most promising technique to remove Sb for field application.Xiaojing Long Xin Wang Xuejun Guo Mengchang He 2020Journal of Environmental Sciences2020,32,4:20

7Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang 2014Biomedical and Environmental Sciences2014,27,5:17
8Downstaging and resection of hepatocellular carcinoma in patients with extrahepatic metastases after stereotactic therapy显示文摘Background:A combination of tyrosine kinase inhibitors(TKIs)and anti-PD-1 antibodies with local regional therapy has elicited yield substantial clinical benefits in patients who have hepatocellular carcinoma(HCC)with extrahepatic metastases.Using this treatment strategy to convert HCC patients with extrahepatic metastases from unresectable to resectable has not yet been reported.Methods:Consecutive hepatocellular carcinoma patients with extrahepatic metastases who received first-line therapy with a combination of TKIs and anti-PD-1 antibodies and at least one local regional therapy were analysed.Results:Nine patients with localized disease who received first-line systemic therapy were enrolled.At baseline,all of them had oligometastatic disease,namely,Barcelona Clinic Liver Cancer stage C(or Chinese Liver Cancer stage IIIB).The most common treatment administered was lenvatinib plus anti-PD-1 antibody and transarterial chemoembolization,and the median time span from systemic therapy to surgery was 3.2(IQR,2.8-6.2)months.Three patients achieved a pathological complete response.Six patients underwent laparoscopic surgery,and the other 3 patients underwent open surgery.After a median follow-up of 10.2(IQR,8.6-20.0)months,7 patients survived without disease recurrence,and 2 experienced tumour recurrence.All patients had any-grade AEs,and 55.6%of the patients experienced grade 3 AEs.Fatigue was the most common AE,followed by elevated aminotransferase levels and hypertension.Conclusions:Stereotactic therapy is a feasible conversion therapy for HCC patients with extrahepatic metastases to become resectable.This is the first study to analyse therapeutic outcomes of patients receiving these therapies for HCC with extrahepatic metastases.Xiaobo Yang Haifeng Xu Bangyou Zuo Xu Yang Jin Bian Junyu Long Dongxu Wang Junwei Zhang Cong Ning Yanyu Wang Ziyu Xun Yunchao Wang Xin Lu Yilei Mao Xinting Sang Haitao Zhao 2021Hepatobiliary Surgery and Nutrition2021,10,4:17

10Laparoscopic vs computerized tomography-guided radiofrequency ablation for large hepatic hemangiomas abutting the diaphragm显示文摘AIM: To compare safety and therapeutic efficacy of laparoscopic radiofrequency(RF) ablation vs computed tomography(CT)-guided RF ablation for large hepatic hemangiomas abutting the diaphragm.METHODS: We retrospectively reviewed our sequential experience of treating 51 large hepatic hemangiomas abutting the diaphragm in 51 patients by CT-guided or laparoscopic RF ablation due to either the presence of symptoms and/or the enlargement of hemangioma.Altogether, 24 hemangiomas were ablated via a CTguided percutaneous approach(CT-guided ablation group), and 27 hemangiomas were treated via a laparoscopic approach(laparoscopic ablation group).RESULTS: The mean diameter of the 51 hemangiomas was 9.6 ± 1.8 cm(range, 6.0-12.0 cm). There was nodifference in the diameter of hemangiomas between the two groups(P > 0.05). RF ablation was performed successfully in all patients. There was no difference in ablation times between groups(P > 0.05). There were 23 thoracic complications in 17 patients: 15(62.5%, 15/24) in the CT-guided ablation group and2(7.4%, 2/27) in the laparoscopic ablation group(P< 0.05). According to the Dindo-Clavien classification,two complications(pleural effusion and diaphragmatic rupture grade Ⅲ) were major in two patients. All others were minor(grade Ⅰ). Both major complications occurred in the CT-guided ablation group. The minor complications were treated successfully with conservative measures, and the two major complications underwent treatment by chest tube drainage and thoracoscopic surgery, respectively. Complete ablation was achieved in 91.7%(22/24) and 96.3%(26/27) in the CT-guided and the laparoscopic ablation groups,respectively(P > 0.05).CONCLUSION: Laparoscopic RF ablation therapy should be used as the first-line treatment option for large hepatic hemangiomas abutting the diaphragm.It avoids thermal injury to the diaphragm and reduces thoracic complications.Jun Gao Jian Kong Xue-Mei Ding Shan Ke Hai-Gang Niu Zong-Hai Xin Chun-Min Ning Shi-Gang Guo Xiao-Long Li Long Zhang Yong-Hong Dong Wen-Bing Sun 2015World Journal of Gastroenterology2015,21,19:16
11Radiofrequency ablation for hepatic hemangiomas: A consensus from a Chinese panel of experts显示文摘Recent studies have shown that radiofrequency(RF) ablation therapy is a safe, feasible, and effective procedure for hepatic hemangiomas, even huge hepatic hemangiomas. RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.Jun Gao Rui-Fang Fan Jia-Yin Yang Yan Cui Jian-Song Ji Kuan-Sheng Ma Xiao-Long Li Long Zhang Chong-Liang Xu Xin-Liang Kong Shan Ke Xue-Mei Ding Shao-Hong Wang Meng-Meng Yang Jin-Jin Song Bo Zhai Chun-Ming Nin Shi-Gang Guo Zong-Hai Xin Jun Lu Yong-Hong Dong Hua-Qiang Zhu Wen-Bing Sun 2017World Journal of Gastroenterology2017,23,39:15

13Performance analysis of ghost imaging lidar in background light environment显示文摘The effect of background light on the imaging quality of three typical ghost imaging(GI) lidar systems(namely narrow pulsed GI lidar, heterodyne GI lidar, and pulse-compression GI lidar via coherent detection) is investigated. By computing the signal-to-noise ratio(SNR) of fluctuation-correlation GI, our analytical results, which are backed up by numerical simulations, demonstrate that pulse-compression GI lidar via coherent detection has the strongest capacity against background light, whereas the reconstruction quality of narrow pulsed GI lidar is the most vulnerable to background light. The relationship between the peak SNR of the reconstruction image andσ(namely, the signal power to background power ratio) for the three GI lidar systems is also presented, and theresults accord with the curve of SNR-σ.CHENJIN DENG LONG PAN CHENGLONG WANG XIN GAO WENLIN GONG SHENSHENG HAN 2017Photonics Research2017,5,5:13

19Current advances in orthodontic pain显示文摘Orthodontic pain is an inflammatory pain that is initiated by orthodontic force-induced vascular occlusion followed by a cascade of inflammatory responses, including vascular changes, the recruitment of inflammatory and immune cells, and the release of neurogenic and pro-inflammatory mediators. Ultimately, endogenous analgesic mechanisms check the inflammatory response and the sensation of pain subsides. The orthodontic pain signal, once received by periodontal sensory endings, reaches the sensory cortex for pain perception through three-order neurons: the trigeminal neuron at the trigeminal ganglia, the trigeminal nucleus caudalis at the medulla oblongata and the ventroposterior nucleus at the thalamus. Many brain areas participate in the emotion,cognition and memory of orthodontic pain, including the insular cortex, amygdala, hippocampus, locus coeruleus and hypothalamus. A built-in analgesic neural pathway—periaqueductal grey and dorsal raphe—has an important role in alleviating orthodontic pain. Currently, several treatment modalities have been applied for the relief of orthodontic pain, including pharmacological, mechanical and behavioural approaches and low-level laser therapy. The effectiveness of nonsteroidal antiinflammatory drugs for pain relief has been validated, but its effects on tooth movement are controversial. However, more studies are needed to verify the effectiveness of other modalities. Furthermore, gene therapy is a novel, viable and promising modality for alleviating orthodontic pain in the future.Hu Long Yan Wang Fan Jian Li-Na Liao Xin Yang Wen-Li Lai 2016International Journal of Oral Science2016,8,2:11
20Grey GM(1,1) Model with Function-Transfer Method for Wear Trend Prediction and its Application显示文摘Trend forecasting is an important aspect in fault diagnosis and work state supervision. The principle, where Grey theory is applied in fault forecasting, is that the forecast system is considered as a Grey system; the existing known information is used to infer the unknown information’s character, state and development trend in a fault pattern, and to make possible forecasting and decisions for future development. It involves the whitenization of a Grey process. But the traditional equal time interval Grey GM (1,1) model requires equal interval data and needs to bring about accumulating addition generation and reversion calculations. Its calculation is very complex. However, the non equal interval Grey GM (1,1) model decreases the condition of the primitive data when establishing a model, but its requirement is still higher and the data were pre processed. The abrasion primitive data of plant could not always satisfy these modeling requirements. Therefore, it establishes a division method suited for general data modeling and estimating parameters of GM (1,1), the standard error coefficient that was applied to judge accuracy height of the model was put forward; further, the function transform to forecast plant abrasion trend and assess GM (1,1) parameter was established. These two models need not pre process the primitive data. It is not only suited for equal interval data modeling, but also for non equal interval data modeling. Its calculation is simple and convenient to use. The oil spectrum analysis acted as an example. The two GM (1,1) models put forward in this paper and the new information model and its comprehensive usage were investigated. The example shows that the two models are simple and practical, and worth expanding and applying in plant fault diagnosis.LUO You xin 1 , PENG Zhu 2 , ZHANG Long ting 1 , GUO Hui xin 1 , CAI An hui 1 1Department of Mechanical Engineering, Changde Teachers University, Changde 415003, P.R.
