2Opportunities and challenges of the Sponge City construction related to urban water issues in China显示文摘Waterlogging is one of the major water issues in most cities of China and directly restricts their urbanization processes.The construction of Sponge City is an effective approach to solving the urban water issues,particularly for the waterlogging.In this study,both the urban issues emerged at the stage of rapid urbanization in China and the demands as well as problems of Sponge City construction related with the water issues were investigated,and the opportunities and challenges for the Sponge City construction in the future were also proposed.It was found that the current stormwater management focused on the construction of gray infrastructures(e.g.,drainage network and water tank) based on the fast discharge idea,which was costly and hard to catch up with the rapid expansion of city and its impervious surface,while green infrastructures(e.g.,river,lake and wetland)were ignored.Moreover,the current construction of Sponge City was still limited to low impacted development(LID) approach which was concentrated on source control measures without consideration of the critical functions of surrounding landscapes(i.e.,mountain,river,wetland,forest,farmland and lake),while application of the integrated urban water system approach and its supported technologies including municipal engineering,urban hydrology,environmental science,social science and ecoscape were relatively weak and needed to be improved.Besides,the lack of special Sponge City plan and demonstration area was also a considerable problem.In this paper,some perspectives on Good Sponge City Construction were proposed such as the point that idea of urban plan and construction should conform to the integral and systematic view of sustainable urban development.Therefore,both the basic theoretical research and the basic infrastructure construction such as monitoring system,drainage facility and demonstration area should be strengthened,meanwhile,the reformation and innovation in the urban water management system and the education system should also be urgently performed.The study was expected to provide a deeper thinking for the current Sponge City construction in China and to give some of suggestions for the future directions to urban plan and construction,as well as urban hydrology discipline.XIA Jun ZHANG YongYong XIONG LiHua HE Shan WANG LongFeng YU ZhongBo 2017Science China Earth Sciences2017,60,4:65

5Heat-sensitive moxibustion for lumbar disc herniation:a meta-analysis of randomized controlled trials显示文摘OBJECTIVE:To assess the efficacy and safety of heat-sensitive moxibustion in the treatment of lumbar disc herniation(LDH).METHODS:Randomized controlled trials(RCTs) involving heat-sensitive moxibustion in the treatment of LDH were retrieved from the Chinese Biological Medical Literature database(1978-20011),Weipu database(1989-2011),Wanfang digital journal(1998-2011),China National Knowledge Internet(1979-2011),PubMed(1966-2011),EMBASE(1980-2011),and Cochrane Library(Issue 1,2011).Hand-search of the relevant journals from the Library of Jiangxi University of Traditional Chinese Medicine was also adopted for the collection of data.Data were extracted and evaluated by two reviewers independently with a specially designed extraction form.The Cochrane Collaboration's RevMan 5.0.20 software was used for data analyses.RESULTS:A total of 6 trials involving 580 patients were included.Meta-analysis showed that the total effectiveness rate in the heat-sensitive moxibustion group was significantly different when compared with conventional moxibustion [RR=1.19,95% CI [1.06,1.33)] and diclofenac sodium [RR=1.47,95% CI [1.17,1.85)],but similar to that of acupuncture.The cure rate in the heat-sensitive moxibustion group was significantly different when compared with conventional moxibustion [RR=1.58,95% CI(1.04,2.40)] and diclofenac sodium [RR=1.91,95% CI(1.01,3.60)],but similar with that of acupuncture.In terms of the Japanese Orthopaedic Association scores,significant differences were noted in subjective indices,objective indices,and daily life subscales.Two trials reported that there were no adverse events over the duration of treatment.CONCLUSION:Compared with conventional moxibustion,acupuncture,and diclofenac sodium,heat-sensitive moxibustion in the treatment of LDH is superior in efficacy.Further large-scale trials are required to define the role of heat-sensitive moxibustion in the treatment of this disease.Rixin Chen Jun Xiong Zhenhai Chi Bo Zhang 2012Journal of Traditional Chinese Medicine2012,32,3:33
6Magnetic resonance diffusion tensor imaging following major ozonated autohemotherapy for treatment of acute cerebral infarction显示文摘Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction,but whether major ozonated autohemotherapy affects remote injury remains poorly understood.Here,we assumed that major ozonated autohemotherapy contributes to recovery of clinical function,possibly by reducing remote injury after acute cerebral infarction.Sixty acute cerebral infarction patients aged 30–80 years were equally and randomly allocated to ozone treatment and control groups.Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy(47 mg/L,100 m L ozone) for 10 ± 2 days.Patients in the control group received medical treatment only.National Institutes of Health Stroke Scale score,modified Rankin scale score,and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased,brain function improved,clinical efficiency significantly increased,and no obvious adverse reactions detected in the ozone treatment group compared with the control group.These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury,and additionally,exhibits high safety.Xiao-na Wu Tao Zhang Jun Wang Xiao-yan Liu Zhen-sheng Li Wei Xiang Wei-qing Du Hong-jun Yang Tie-gen Xiong Wen-ting Deng Kai-run Peng Su-yue Pan 2016Neural Regeneration Research2016,11,7:32
7Waist Circumference Reference Values for Screening Cardiovascular Risk Factors in Chinese Children and Adolescents显示文摘Objectives To explore the optimal threshold values of waist circumference(WC)for detecting cardiovascular(CV)risk factors among Chinese children and adolescents.Methods Association of WC with CV risk factors was studied among 65 898 children aged 7-18 years whose data were pooled from nine previous studies in China.CV risk factors in this study included hypertension(blood pressure above 95 percentile levels),dyslipidemia(with one or more of the following three indexes:TG≥1.7 mmol/L,TC≥5.18 mmol/L,and HDL-C≤1.04 mmol/L)and elevated glucose level(fasting plasma glucose ≥5.6 mmol/L).Receive-operating characteristic analysis(ROC)and logistic regression were employed to derive optimal age-and sex-specific waist circumference references for predicting CV risk factors.Results A slight increasing trend of CV risk factors was observed starting from the 75th percentile of waist circumference in the study population,while a remarkable increasing trend occurred from the 90th percentile.The optimal waist circumference thresholds for predicting high blood pressures were at the 75th percentile for both boys and girls,which was at the 90th percentiles for detecting at least two of the above three CV risk factors.In comparison with children with waist circumference below the 75th percentile,the odds ratio of two CV risk factors doubled among children with waist circumference between the 75th and the 90th percentile,and increased by 6 times among children with waist circumference above the 90th percentile.The trend of high blood pressure increasing with waist circumference remained significant after having been stratified by BMI category.Conclusion The 75th and the 90th percentiles of WC are the optimal cut-off points for predicting an increased and a substantially increased risk of CV factors in Chinese children and adolescents,respectively.GUAN-SHENG MA CHENG-YE JI JUN MA JIE MI R1TA YT SLING FENG XIONG WEI-LI YAN XIAO-QI HU YAN-PING LI SONG-M1NG DU HONG-YUN FANG AND J1NG-XIONG JIANG 2010Biomedical and Environmental Sciences2010,23,1:25
8Efficacy and safety evaluation of icotinib in patients with advanced non-small cell lung cancer显示文摘Objective: To evaluate the efficacy and safety of icotinib hydrochloride in patients with advanced non-small cell lung cancer (NSCLC). Methods: A total of 89 patients with stage ⅢB or IV NSCLC received icotinib at a dose of 125 mg administered 3 times a day. Icotinib treatment was continued until disease progression or development of unacceptable toxicity. Results: A total of 89 patients were assessable. In patients treated with icotinib, the overall response rate (RR) was 36.0% (32/89), and the disease control rate (DCR) was 69.7% (62/89). RR and DCR were significantly improved in patients with adenocarcinoma versus non-adenocarcinoma (P<0.05). The symptom improvement rate was 57.3% (51/89), and the main symptoms improved were cough, pain, chest distress, dyspnea, and Eastern Cooperative Oncology Group performance status. The main toxic effects were rash [30/89 (33.7%)] and diarrhea [15/89 (16.9%)]. The level of toxicity was typically low. Conclusions: The use of icotinib hydrochloride in the treatment of advanced NSCLC is efficacious and safe, and its toxic effects are tolerable.Aiqin Gu Chunlei Shi Liwen Xiong Tianqing Chu Jun Pei Baohui Han 2013Chinese Journal of Cancer Research2013,25,1:22
9Curative effect of heat-sensitive moxibustion on chronic persistent asthma: a multicenter randomized controlled trial显示文摘OBJECTIVE:To compare the curative effects of heat-sensitive moxibustion with conventional drugs on chronic persistent asthma and seek a valuable therapy to replaceWestern Medicine.METHODS:The participants in this multi-center,randomized,and controlled study were randomly divided into two groups:group A(n=144),treated with heat-sensitive moxibustion(50 sessions)and group B(n=144),treated with Seretide(salmeterol50μg/fluticasone 250μg,twice a day).The scores of asthma control test(ACT),forced expiratory volume in 1 second(FEV1),peak expiratory flow(PEF),and attack frequency were measured after 15,30,60,and 90 days of treatment.Patients followed up3 and 6 months after treatment.RESULTS:There was a significant difference(P=0.0002)in the ACT score and lung function between the two groups after 3 months of treatment and(P=0.000 03)during the follow-up visits.In addition,heat-sensitive moxibustion reduced attack frequency in the period from inclusion to the6-month follow-up visit.CONCLUSION:This study shows that heat-sensitive moxibustion may have a comparable curative effect toSeretide(salmeterol/fluticasone)on asthma.Rixin Chen Mingren Chen Jun Xiong Zhenhai Chi B0 Zhang Ning Tian Zhenhua Xu Tangfa Zhang Wanyao Li Wei Zhang Xiaofeng Rong Zhen Wang Gang Sun Baohe Ge Guoxiong Yu Nanchang Song 2013Journal of Traditional Chinese Medicine2013,33,5:20

11Three-dimensional Finite Element Analysis of the Mechanical Properties of Helical Thread Connection显示文摘Conventional analytical and numerical methods for the mechanical properties of helical threads are relied on many assumptions and approximations and thus hardly yield satisfied results. A parameterized 3D finite element model of bolted joints with real helical thread geometry is established and meshed with refined hexahedral elements. The Von Mises plasticity criterion, kinematic hardening rule of materials and interfacial contacts are employed to make it possible for the suggested model be able to approach real assembly conditions. Then, the mechanical properties of bolted joints with different thread pitches, thread numbers and modular ratios are investigated, including the contact pressure distribution at joint interfaces, the axial load distribution and stress concentration in screw threads during the loading and unloading process. Simulation results indicate that the load distribution in screw threads produced by the suggested model agrees well the results from CHEN's photoelastic tests. In addition, an interesting phenomenon is found that tightening the bolt with a large preload first and then adjusting the clamping force by unloading can make the load distribution more uniform and reduce the maximum residual equivalent stress in thread roots by up to 40%. This research provides a simple and practical approach to constructing the 3D finite element model and predicting the mechanical properties of helical thread connection.YANG Guoqing HONG Jun ZHU Linbo LI Baotong XIONG Meihua WANG Fei 2013Chinese Journal of Mechanical Engineering2013,26,3:19
12Single-cell transcriptomics reveals regulators underlying immune cell diversity and immune subtypes associated with prognosis in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is an aggressive malignancy with extremely skewed ethnic and geographic distributions.Increasing evidence indicates that targeting the tumor microenvironment(TME)represents a promising therapeutic approach in NPC,highlighting an urgent need to deepen the understanding of the complex NPC TME.Here,we generated single-cell transcriptome profiles for 7581 malignant cells and 40,285 immune cells from fifteen primary NPC tumors and one normal sample.We revealed malignant signatures capturing intratumoral transcriptional heterogeneity and predicting aggressiveness of malignant cells.Diverse immune cell subtypes were identified,including novel subtypes such as CLEC9A^+dendritic cells(DCs).We further revealed transcriptional regulators underlying immune cell diversity,and cell–cell interaction analyses highlighted promising immunotherapeutic targets in NPC.Moreover,we established the immune subtype-specific signatures,and demonstrated that the signatures of macrophages,plasmacytoid dendritic cells(pDCs),CLEC9A^+DCs,natural killer(NK)cells,and plasma cells were significantly associated with improved survival outcomes in NPC.Taken together,our findings represent a unique resource providing in-depth insights into the cellular heterogeneity of NPC TME and highlight potential biomarkers for anticancer treatment and risk stratification,laying a new foundation for precision therapies in NPC.Yu-Pei Chen Jian-Hua Yin Wen-Fei Li Han-Jie Li Dong-Ping Chen Cui-Juan Zhang Jia-Wei Lv Ya-Qin Wang Xiao-Min Li Jun-Yan Li Pan-Pan Zhang Ying-Qin Li Qing-Mei He Xiao-Jing Yang Yuan Lei Ling-Long Tang Guan-Qun Zhou Yan-Ping Mao Chen Wei Ke-Xu Xiong Hong-Bo Zhang Shi-Da Zhu Yong Hou Ying Sun Michael Dean Ido Amit Kui Wu Dong-Ming Kuang Gui-Bo Li Na Liu Jun Ma 2020Cell Research2020,30,11:19

15Overexpression of HMGB1 A-box reduced lipopolysaccharide-induced intestinal inflammation via HMGB1/TLR4 signaling in vitro显示文摘AIM: To investigate the inhibitory effects and mechanism of high mobility group box(HMGB)1 A-box in lipopolysaccharide(LPS)-induced intestinal inflammation.METHODS: Overexpression of HMGB1 A-box in human intestinal epithelial cell lines(SW480 cells) was achieved using the plasmid p EGFP-N1. HMGB1 A-box-overexpressing SW480 cells were stimulated with LPS and co-culturing with human monocyte-like cell lines(THP-1 cells) using a Transwell system, compared with another HMGB1 inhibitor ethyl pyruvate(EP). The m RNA and protein levels of HMGB1/toll-like receptor(TLR) 4 signaling pathways [including HMGB1, TLR4, myeloid differentiation factor88(MYD88), Phosphorylated Nuclear Factor κB(p NF-κB) p65] in the stimulated cells were determined by realtime polymerase chain reaction and Western blotting. The levels of the proinflammatory mediators [including HMGB1, interleukin(IL)-1β, IL-6 and tumor necrosis factor(TNF)-α] in the supernatants of the stimulated cells were determined by ELISA.RESULTS: EP downregulated the m RNA and protein levels of HMGB1, inhibited the TLR4 signaling pathways(TLR4, MYD88 and p NF-κB p65) and reduced the secretion of proinflammatory mediators(HMGB1, IL-1β, IL-6 and TNF-α) in the SW480 and THP-1 cells activated by LPS but not in the unstimulated cells. Activated by LPS, the overexpression of HMGB1 A-box in the SW480 cells also inhibited the HMGB1/TLR4 signaling pathways and reduced the secretion of these proinflammatory mediators in the THP-1 cells but not in the transfected and unstimulated cells. CONCLUSION: HMGB1 A-box, not only EP, can reduce LPS-induced intestinal inflammation through inhibition of the HMGB1/TLR4 signaling pathways.Fu-Cai Wang Jing-Xuan Pei Jun Zhu Nan-Jin Zhou Dong-Sheng Liu Hui-Fang Xiong Xiao-Qun Liu Dong-Jia Lin Yong Xie 2015World Journal of Gastroenterology2015,21,25:16
16Endoloop ligation after endoscopic mucosal resection using a transparent cap: A novel method to treat small rectal carcinoid tumors显示文摘BACKGROUND Local endoscopic resection is an effective method for the treatment of small rectal carcinoid tumors, but remnant tumor at the margin after resection remains to be an issue.AIM To evaluate the efficacy and safety of resection of small rectal carcinoid tumors by endoloop ligation after cap-endoscopic mucosal resection(LC-EMR) using a transparent cap.METHODS Thirty-four patients with rectal carcinoid tumors of less than 10 mm in diameter were treated by LC-EMR(n = 22) or endoscopic submucosal dissection(ESD)(n =12) between January 2016 and December 2017. Demographic data, complete resection rates, pathologically complete resection rates, operation duration, and postoperative complications were collected. All cases were followed for 6 to 30 mo.RESULTS A total of 22 LC-EMR cases and 12 ESD cases were enrolled. The average age was48.18 ± 12.31 and 46.17 ± 12.57 years old, and the tumor size was 7.23 ± 1.63 mm and 7.50 ± 1.38 mm, respectively, for the LC-EMR and ESD groups. Resection time in the ESD group was longer than that in the LC-EMR group(15.67 ± 2.15 min vs 5.91 ± 0.87 min; P < 0.001). All lesions were completely resected at one time. No perforation or delayed bleeding was observed in either group.Pathologically complete resection(P-CR) rate was 86.36%(19/22) and 91.67%(11/12) in the LC-EMR and ESD groups(P = 0.646), respectively. Two of the three cases with a positive margin in the LC-EMR group received transanal endoscopic microsurgery(TEM) and tumor cells were not identified in the postoperative specimens. The other case with a positive margin chose follow-up without further operation. One case with remnant tumor after ESD received further local ligation treatment. Neither local recurrence nor lymph node metastasis was found during the follow-up period.CONCLUSION LC-EMR appears to be an efficient and simple method for the treatment of small rectal carcinoid tumors, which can effectively avoid margin remnant tumors.Ding-Guo Zhang Su Luo Feng Xiong Zheng-Lei Xu Ying-Xue Li Jun Yao Li-Sheng Wang 2019World Journal of Gastroenterology2019,25,10:15
17Effect of Kuanxiong Aerosol(宽胸气雾剂)on Patients with Angina Pectoris:A Non-inferiority Multi-center Randomized Controlled Trial显示文摘Objective: To evaluate the effect and safety of Kuanxiong Aerosol(宽胸气雾剂, KA) on patients with angina pectoris. Methods: Block randomization was performed to randomly allocate 750 patients into KA(376 cases) and control groups(374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA(0.6 m L per spray). The control group received 1 sublingual nitroglycerin tablet(NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment(1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors influencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society(CCS) classes of angina. Results: The 5-min remission rates in the KA and control groups were not significantly different(94.41% vs. 90.64%, P>0.05). The angina CCS class significantly influenced the rate of remission (95% confidence interval = 0.483–0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSⅠ and Ⅳ subgroups(P>0.05), while they were significantly better for KA in the CCSⅡ and Ⅲ subgroups(P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was significantly lower in the KA group than in the control group for the CCSⅡ and Ⅲ subgroups(9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01). Conclusions: KA is not inferior to NT in the remission of angina. Furthermore, in CCSⅡ and Ⅲ patients, KA is superior to NT, with a lower incidence of adverse reactions.YANG Qiao-ning BAI Rui-na DONG Guo-ju GE Chang-jiang ZHOU Jing-min HUANG Li HE Yan WANG Jun REN Ai-hua HUANG Zhan-quan ZHU Guang-li LU Shu XIONG Shang-quan XIAN Shao-xiang ZHU Zhi-jun SHI Da-zhuo LU Shu-zheng LI Li-zhi CHEN Ke-ji 2018Chinese Journal of Integrative Medicine2018,24,5:15
18Inhibition of hepatitis B virus by oxymatrine in vivo显示文摘AIM To investigate the anti-HBV effect ofoxymatrine (oxy) in vivo.METHODS HBV transgenic mice were producedby micro-injection of a 4.2kb fragmentcontaining the complete HBV genomes.Expression level of HBsAg and HBcAg in thetransgenic mice liver was determined byimmunohistochemical assay.RESULTS Four groups (6 mice in each group)were injected intraperitoneally with oxy at thedosage of 100,200, and 300 mg/kg or with salineonce a day for 30 days. Both HBsAg and HBcAgwere positive in livers of all the six mice in thecontrol group (injected with saline), and werepositive in livers of two mice in 100 mg/kg groupand 300mg/kg group. In 200mg/kg group,HBsAg and HBcAg were negative in livers of allthe six mice. Based on the results, 200 mg/kg isthe ideal dosage to explore the effect of oxy atdifferent time points. According to the oxytreatment time, mice were divided into fourgroups: 10 d, 20 d, 30 d and 60 d (4 mice in eachgroup). Each mouse underwent liver biopsy twoweeks before the treatment of oxy. Down-regulation of HBsAg and HBcAg appeared aftertreatment of oxymatrine for 10 d and 20 d, Dane-like particles disappeared after the treatment ofoxy for 20d under electron microscopy,however, the expression level of HBsAg andHBcAg returned to normal 60 d later after oxytreatment.CONCLUSION oxymatrine can reduce thecontents of HBsAg and HBcAg in transgenic miceliver, longer treatment time and larger dosagedo not yield better effects.Xiao Song Chen1 Guo Jun Wang1 Xiong Cai1 Hong Yu Yu2 Yi Ping Hu3 1Department of Infectious Diseases, Changzheng Hospital, the Second Military Medical University, Shanghai 200003, China2Department of Pathology, 3Department of Cell Biology, Department of Basic Medicine, the Second Military Medical University, Shanghai 200433, China 2001World Journal of Gastroenterology2001,7,1:13
19Stretching and imaging studies of single DNA molecules显示文摘DNA molecules were stretched on silanized mica surface with the molecular combing technique, and detected with fluorescence microscopy and atomic force microscopy. Meantime, DNA molecules were stretched with a modified dynamic molecular combing technique and studied with atomic force microscopy. The results indicate that, compared with the dynamic molecular combing technique, the modified dynamic molecular combing technique has advantages of less-sample demand and less contamination to sample; as compared with the molecular combing technique, it has better aligning effect and reproducibility. Combination of this kind of DNA molecular manipulating technique with the single DNA molecule detecting technique by atomic force microscopy and fluorescence microscopy will play an important role in the basic research of molecular dynamics and the application of gene research.ZHANG Yi CHEN Shengfu OUYANG Zhenqian HU Jun XIONG Qihua LI Bin HUANG Yibo LI Minqian JIN Chengzhi 2000Chinese Science Bulletin2000,45,15:13
20Measurement of wireless pressure sensors fabricated in high temperature co-fired ceramic MEMS technology显示文摘High temperature co-fired ceramics(HTCCs) have wide applications with stable mechanical properties,but they have not yet been used to fabricate sensors.By introducing the wireless telemetric sensor system and ceramic structure embedding a pressure-deformable cavity,the designed sensors made from HTCC materials(zirconia and 96% alumina) are fabricated,and their capacities for the pressure measurement are tested using a wireless interrogation method.Using the fabricated sensor,a study is conducted to measure the atmospheric pressure in a sealed vessel.The experimental sensitivity of the device is 2 Hz/Pa of zirconia and 1.08 Hz/Pa of alumina below 0.5 MPa with a readout distance of 2.5 cm.The described sensor technology can be applied for monitoring of atmospheric pressure to evaluate important component parameters in harsh environments.Ji-jun XIONG Shi-jun ZHENG Ying-ping HONG Jun LI Ying-lin WANG Wei WANG Qiu-lin TAN 2013Journal of Zhejiang University-Science C(Computers and Electronics)2013,14,4:13
