1Nasopharyngeal carcinoma incidence and mortality in China in 2010显示文摘Nasopharyngeal carcinoma(NPC) is common in South China. Although regional epidemiological data on NPC in China is available, national epidemiological data have been unavailable up to now. The goal of this study was to analyze the NPC incidence and mortality data in some domestic cancer registries, estimate these rates in China in 2010, and provide scientific information that can be harnessed for NPC control and prevention. To accomplish this goal, NPC incidence and mortality data for 2010 were collected from 145 Chinese cancer registries from which data were included in the 2013 National Cancer Registry Annual Report. Such indices as its incident and death numbers, crude rates, age-standardized rates and truncated rates were calculated and analyzed. The incidence and mortality in China and constituent areas were estimated according to the national population in 2010. An estimated 41,503 new cases and 20,058 deaths were attributed to NPC in China in 2010, accounting for 1.34% of all new cancer cases and 1.03% of all cancer-related deaths that year in China. Crude incidence and mortality were 3.16/100,000 and 1.53/100,000, respectively. World age-standardized incidence and mortality were 2.44/100,000 and 1.18/100,000, respectively. Incidence and mortality were higher among males than among females and slightly higher in urban areas than in rural areas. Among seven Chinese administrative regions, NPC incidence and mortality were obviously higher in South China than in other regions and lowest in North China. The male and female age-specific incidence and mortality both rose quickly from age 25-29 years, but peaked at different ages and varied by location. These results demonstrated that NPC incidence and mortality in China especially in South China were at high levels in the world, and suggested that control and prevention efforts should be enhanced.Kuang-Rong Wei Rong-Shou Zheng Si-Wei Zhang Zhi-Heng Liang Zhi-Xiong Ou Wan-Qing Chen 2014Chinese Journal of Cancer2014,33,8:45
2Incidence and mortality of liver cancer in China, 2010显示文摘Liver cancer is a common malignant tumor in China and a major health concern. We aimed to estimate the liver cancer incidence and mortality in China in 2010 using liver cancer data from some Chinese cancer registries and provide reference for liver cancer prevention and treatment. We collected and evaluated the incidence and mortality data of liver cancer in 2010 from 145 cancer registries, which were included in the 2013 Chinese Cancer Registry Annual Report, calculated crude, standardized, and truncated incidences and mortalities, and estimated new liver cancer cases and deaths from liver cancer throughout China and in different regions in 2010 from Chinese practical population. The estimates of new liver cancer cases and deaths were 358,840 and 312,432, respectively, in China in 2010. The crude incidence, age-standardized rate by Chinese standard population(ASR China), and age-standardized rate by world standard population(ASR world) were 27.29/100,000, 21.35/100,000, and 20.87/100,000, respectively; the crude, ASR China, and ASR world mortalities were 23.76/100,000, 18.43/100,000, and 18.04/100,000, respectively. The incidence and mortality were the highest in western regions, higher in rural areas than in urban areas, and higher in males than in females. The age-specific incidence and mortality of liver cancer showed a rapid increase from age 30 and peaked at age 80-84 or 85+. Our results indicated that the 2010 incidence and mortality of liver cancer in China, especially in undeveloped rural areas and western regions, were among high levels worldwide. The strategy for liver cancer prevention and treatment should be strengthened.Kuang-Rong Wei Xia Yu Rong-Shou Zheng Xia-Biao Peng Si-Wei Zhang Ming-Fang Ji Zhi-Heng Liang Zhi-Xiong Ou Wan-Qing Chen 2014Chinese Journal of Cancer2014,33,8:46

5Mechanization technology:The key to sugarcane production in China显示文摘Sugarcane is an important cash crop in southern China now planted on about 1.5 million ha in the main production areas in Guangxi,Zhuang Autonomous Region and Yunnan,Guangdong,and Hainan Provinces.Since the cost of labor in China is increasing rapidly and the price of local sugar is uncompetitive with the product from mechanized international producers,China needs to change its sugarcane production methods from manual work to mechanization in order to catch up with international trends in this global industry.Although a lot of effort in China have gone into sugarcane mechanization since the 1960s,the overall level of mechanization in sugarcane production is still only approximately 30%,which is about 20%lower than that achieved in the other main field crops.Almost all of the sugarcane grown in China is still harvested by hand.In order to summarize past experience and promote the mechanization of sugarcane production in China,this paper reviews the whole process of developing mechanization since 1960s and describes the current state of sugarcane mechanization in China.The research currently being undertaken and the main obstacles to be overcome in developing a mechanized sugarcane production system,are described.The design and testing of sugarcane harvesting machinery and its key components has been a significant research area by some Chinese universities,research institutes,and manufacturing companies in these past decades.This paper reviews that research and outlines the main achievements which have been made in this area.Mechanized harvesting systems for sugarcane,and the appropriate harvesting patterns suitable for different growing conditions applying in China,have also been studied.The paper concludes with some comments on the future directions for progress in China’s mechanization of sugarcane production and some policy suggestions to facilitate the industry's transition.Ou Yinggang Malcolm Wegener Yang Dantong Liu Qingting Zheng Dingke Wang Meimei Liu Haochun 2013International Journal of Agricultural and Biological Engineering2013,6,1:13
6Addition of hepatectomy decreases liver recurrence and leads to long survival in hilar cholangiocarcinoma显示文摘AIM:To evaluate hepatic recurrence and prognostic factors for survival in patients with surgically resected hilar cholangiocarcinoma in a single institution over the last 13 years. METHODS:From 1994 to 2007,all patients with hilar cholangiocarcinoma referred to a surgical clinic were evaluated.Demographic data,tumor characteristics, and outcome were analyzed retrospectively.Outcome was compared in patients who underwent additional liver resection with resection of the tumor. RESULTS:Of the 69 patients submitted to laparotomy for tumor resection,curative resection(R0 resection) was performed in 40 patients,and palliative resection in 29.Thirty-one patients had only duct resection,and 38 patients had combined duct resection with liver resection including 34 total or part caudate lobes. Curative rates with the combined hepatectomy were significantly improved compared with those without additional hepatectomy(27/38 vs 13/31;χ2=5.94,P <0.05).Concomitant liver resection was associated with a decreased incidence of initial recurrence in liver one year after surgery(11/38 vs 23/31;χ2=13.98, P<0.01).The 3-year survival rate after R0 resection was 30.7%and was 10.5%for palliative resection.R0 resection improved the 3-year survival rate(30.7%vs 10.5%;χ2=12.47,P<0.01).CONCLUSION:Hepatectomy,especially including the caudate lobe combined with bile duct resection should be considered standard treatment to cure hilar cholangiocarcinoma.Zheng Shi Ming-Zhi Yang Qing-Liang He Rong-Wen Ou You-Ting Chen 2009World Journal of Gastroenterology2009,15,15:12

8Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12

10Two-dimensional ultrathin MoS2-modified black Ti^3+-TiO2 nanotubes for enhanced photocatalytic water splitting hydrogen production显示文摘Two-dimensional (2D) ultrathin MoS2-modified black Ti^3+-TiO2 nanotubes were fabricated using an electrospinning-hydrothermal treatment-reduction method.Bare TiO2 nanotubes were fabricated via electrospinning.Then,2D MoS2 lamellae were grown on the surface of the nanotubes and Ti^3+/Ov ions were introduced by reduction.The photocatalytic performance of the 2D MoS2/Ti^3+-TiO2 nanotubes was^15 times better than that of TiO2.The HER enhancement of the MoS2/Ti^3+-TiO2 nanotubes can be attributed to the Pt-like behavior of 2D MoS2 and the presence of Ti^3+-ions,which facilitated the quick diffusion of the photogenerated electrons to water,reducing the H2 activation barrier.The presence of Ov ions in the nanotubes and their hollow structure increased their solar utilization.Wei Ou Jiaqi Pan Yanyan Liu Shi Li Hongli Li Weijie Zhao Jingjing Wang Changsheng Song Yingying Zheng Chaorong Li 2020Journal of Energy Chemistry2020,29,4:7
11Separate lateral parametrial lymph node dissection improves detection rate of parametrial lymph node metastasis in early-stage cervical cancer: 10-year clinical evaluation in a single center in China显示文摘Objective: To investigate the clinical significance of separate lateral parametrial lymph node dissection(LPLND) in improving parametrial lymph node(PLN) and its metastasis detection rate during radical hysterectomy for early-stage cervical cancer.Methods: From July 2007 to August 2017, 2,695 patients with cervical cancer in stage IB1-IIA2 underwent radical hysterectomy were included. Of these patients, 368 underwent separate dissection of PLNs using the LPLND method, and 2,327 patients underwent conventional radical hysterectomy(CRH). We compared the surgical parameters, PLN detection rate and PLN metastasis rate between the two groups.Results: Compared with CRH group, the rate of laparoscopic surgery was higher(60.3% vs. 15.9%, P<0.001),and the blood transfusion rate was lower(19.0% vs. 29.0%, P<0.001) in the LPLND group. PLNs were detected in 356 cases(96.7%) in the LPLND group, and 270 cases(11.6%) in the CRH group(P<0.001), respectively. The number of PLNs detected in the LPLND group was higher than that in the CRH group(median 3 vs. 1, P<0.001).The PLN metastases were detected in 25 cases(6.8%) in the LPLND group, and 18 cases(0.8%) in the CRH group(P<0.001), respectively. In multivariable analysis, LPLND is an independent factor not only for PLN detection [odds ratio(OR)=228.999, 95% confidence interval(95% CI): 124.661-420.664;P<0.001], but also for PLN metastasis identification(OR=10.867, 95% CI: 5.381-21.946;P<0.001).Conclusions: LPLND is feasible and safe. The surgical method significantly improves the detection rate of PLN and avoids omission of PLN metastasis during radical hysterectomy for early-stage cervical cancer.Dan Zhao Bin Li Shan Zheng Zhengjie Ou Yanan Zhang Yating Wang Shuanghuan Liu Gongyi Zhang Guangwen Yuan 2020Chinese Journal of Cancer Research2020,32,6:7

15Efficient and stable non-doped deep-blue organic light emitting diode based on an anthracene derivative显示文摘A new anthracene derivative 9,10-bis[3,5-di(4-tert-butylphenyl)phenyl]anthracene (BPPA) was synthesized via Suzuki coupling reaction and characterized by 1H NMR spectrum,mass spectrum,and elemental analysis.BPPA exhibits deep-blue emission both in solution and in solid thin film.This compound has a non-planar structure that results in high thermal stability and the phenomenon of polymorphism.The non-doped device based on this material shows stable deep-blue emission with the 1931 Commission international de I'Eclairage (CIE) coordinate of (0.15,0.05) under different applied voltages.The device exhibits the maximum external quantum efficiency of 2.2% at 14.9 mA/cm2 with luminance of 105 cd/m2.WANG ZhiQiang ZHENG CaiJun LIU Heng OU XueMei ZHANG XiaoHong 2011Science China Chemistry2011,54,4:5
16Desmoglein 2(DSG2) Is A Receptor of Human Adenovirus Type 55 Causing Adult Severe Community-Acquired Pneumonia显示文摘Human adenovirus type 55(HAdV-B55) is a re-emergent acute respiratory disease pathogen that causes adult communityacquired pneumonia(CAP). Previous studies have shown that the receptor of HAdV-B14, which genome is highly similar with HAdV-B55, is human Desmoglein 2(DSG2). However, whether the receptor of HAdV-B55 is DSG2 is undetermined because there are three amino acid mutations in the fiber gene between HAdV-B14 and HAdV-B55. Here, firstly we found the 3T3 cells, a mouse embryo fibroblast rodent cell line which does not express human DSG2, were able to be infected by HAdV-B55 after transfected with pcDNA3.1-DSG2, while normal 3T3 cells were still unsusceptible to HAdV-B55 infection. Next, A549 cells with h DSG2 knock-down by siRNA were hard to be infected by HAdV-B3/-B14/-B55, while the control siRNA group was still able to be infected by all these types of HAdVs. Finally, immunofluorescence confocal microscopy indicated visually that Cy3-conjugated HAdV-B55 viruses entered A549 cells by binding to DSG2 protein.Therefore, DSG2 is a major receptor of HAdV-B55 causing adult CAP. Our finding is important for better understanding of interactions between adenoviruses and host cells and may shed light on the development of new drugs that can interfere with these processes as well as for the development of potent prophylactic vaccines.Jing Zhang Kui Ma Xiangyu Wang Yinbo Jiang Shan Zhao Junxian Ou Wendong Lan Wenyi Guan Xiaowei Wu Heping Zheng Bin Yang Chengsong Wan Wei Zhao Jianguo Wu Qiwei Zhang 2021Virologica Sinica2021,36,6:4
17Deposition of sandstorms in a vegetation-covered sand dune in Ejin Oasis and its characteristics显示文摘“Ejin Section” found in a typical vegetation-covered sand dune in Ejin Oasis was investigated. In this study, 263 samples were taken from the section for grain-size analysis, 25 for chemical analysis, 11 for 14C dating and 6 for scanning electron microscope (SEM). The results of the study indicate that 3 types of the sediments in the section can be identified, YS, LS and ST. YS, homogeneous yellow-brown dune sands, is equal to those of inland deserts, LS, loess-like sandy soils, is the same as the sandy loess in the middle Yellow River and modern falling dusts, and ST, sandy sediments interbeded with the deadwood and defoliation of Tamarix spp, represents the depositional process of the section interrupted by abrupt changes in climate. The Ejin Section has recorded the repeated dust-storms or sandstorms since 2500 yr BP and the peak periods of the dust-storms or sandstorms revealed by the section are consistent with the records of “dust rains” in historical literatures, indicating that the change of climate is a key factor to increase sandstorms or dust-storms, whereas, “artificial” factor may only be an accelerating one for desertification.WENXiaohao LI Baosheng WANG Wei LI Sen OU Xianjiao ZHENG Yanming 2006Journal of Geographical Sciences2006,16,4:3
18Regional homogeneity on resting state fMRI in patients with tinnitus显示文摘Objective:To study central functional network connections and their alterations in tinnitus patients using fMRI.Methods:Regional homogeneity(ReHo) values on fMRI were obtained from 18 tinnitus patients and 20 age and gender-matched control subjects.ReHo values were compared between tinnitus patients and control subjects to evaluate functional network connection differences.Results:Tinnitus patients showed increased ReHo values in gyrus frontalis inferior and decreased ReHo values in the anterior lobe of cerebellum in comparison with the controls.Analysis of functional network connection from the gyrus frontalis interior shows stronger connections to the middle brain(FWE,P < 0.001) and right ventral striatum(FEW,P < 0.05,small volume correction).Conclusions:The fMRI results indicate that both auditory and non-auditory centers play important roles in tinnitus.Functional connections among the auditory cortex,thalamus,medial temporal gyrus,parahippocampal gyrus and insula may be an underlying cause for the development of tinnitus.Haidi Yang Yiqing Zheng Yongkang Ou Xiayin Huang 2014Journal of Otology2014,9,4:3
19Differential Responses to UVB Irradiation in Human Keratinocytes and Epidermoid Carcinoma Cells显示文摘Objective To examine UVB-induced responses in normal human keratinocytes (HaCaT) and epidermoid carcinoma cells (A431) at the cellular and molecular level, and investigated the protective effect of salidroside. Methods Cells irradiated by UVB at various dosage and their viability was assessed by MTT assays, cell cycle was analysed by flow cytometry. The expression of NF-κB, BCL-2, and CDK6 after 50 J/m 2 UVB irradiation were detected by RT-PCR and western blotting. Results Our results confirmed greater tolerance of A341 cells to UVB-induced damage such as cell viability and cell cycle arrest, which was accompanied by differential expression changes in NF-κB, BCL-2, and CDK6. UVB exposure resulted in HaCaT cells undergoing G 1 -S phase arrest. When treated with salidroside, HaCaT survival was significantly enhanced following exposure to UVB, suggesting great therapeutic potential for this compound. Conclusion Taken together, our study suggests that A431 respond differently to UVB than normal HaCaT cells, and supports a role for NF-κB, CDK6, and BCL-2 in UVB-induced cell G 1 -S phase arrest. Furthermore, salidroside can effectively protect HaCaT from UVB irradiation.ZHOU Mei Juan ZHENG Li GUO Ling LIU Wei Ling LV Chao JIANG Li Hong OU Cheng Shan DING Zhen Hua 2012Biomedical and Environmental Sciences2012,25,5:2
20Revised Super-long Down-regulation Protocol Improves the Outcome of Infertile Patients with Repeated Implantation Failure in IVF/ICSI-ET显示文摘Objective To investigate the outcome of revised super-long down-regulation protocol(RSDP) for in vitro fertilization / intracytoplasmic sperm injection-embryo transfer(IVF/ICSI-ET) in the special infertile patients with repeated implantation failure(RIF).Methods Patients with RIF were divided into RSDP group and routine long downregulation protocol(RLDP) group. In RSDP group, gonadotropin releasing hormone agonist(GnRHa) was injected intramuscularly by 2.5 mg in mid-luteal phase for the first time and 1.25 mg after 28 d; gonadotropin(Gn) was started 14 d later after the second GnRHa dose. IVF/ICSI-ET was performed according to the routine procedure. The clinical outcomes of RSDP group were compared with those of RLDP group.Results In RSDP group, the number of retrieved oocytes and valid embryos was significantly lower(P<0.05); there were no significant differences about fertilization rate(P>0.05); both good-quality embryo rate and implantation rate were significantly increased(P<0.005); clinical pregnancy rate was obviously improved(P<0.05), as compared with RLDP group.Conclusion RSDP can improve the IVF outcomes significantly in RIF patients.Min-feng SHI Tie ZHOU Ying WANG Guang-hua CHEN Ming ZHU Jun OU Hui DU Tao-fei YAN Di SONG Ju-fen ZHENG Hui-qin ZHANG Ning HUI Ying-hao SUN 2014Journal of Reproduction and Contraception2014,25,2:2
