1Five-year plans, China finance and their consequences显示文摘An important factor influencing corporate finance and economic growth in China lies in its government sponsored industrial policies. Examining China's five-year plans during 1991–2010, we find that state-owned firms in government supported industries enjoy faster growth in initial public offerings and higher offer prices. Further, they enjoy faster growth in loans granted by major national banks. However, this preferential access to capital by state-owned firms appears to be achieved at the expense of non-state-owned firms which are crowded out. Government support induces more investment but also brings more overinvestment, which mainly comes from the non-state sector.Finally, supported industries have higher stock market returns and cash flow growth that dampen when state ownership increases.Donghua Chen Oliver Zhen Li Fu Xin 2017China Journal of Accounting Research2017,,3:76

6Effect of different sources and levels of iron in the diet of sows on iron status in neonatal pigs显示文摘This study was conducted to determine the effects of maternal dietary supplementation of ferrous glycine chelate(Fe-Gly) and ferrous sulfate monohydrate(FeSO_4·H_2O) on the relative organ weight, tissue iron contents, red blood cells(RBC), hemoglobin concentration(HGB) and hematocrit(HCT) in blood, as well as ferritin(Fn), serum iron(SI), and total iron binding capacity(TIBC) in serum of newborn piglets.Forty-five sows(Landrace × Large white, mean parity 3 to 4, no significant differences in BW) were randomly allotted to 9 treatments(n=5 sows/treatment): control(basal diet with no Fe supplementation), the basal diet supplemented with 50, 80, 110 or 140 mg Fe/kg as Fe-Gly, and the basal diet supplemented with 50, 80, 110 or 140 mg Fe/kg as FeSO_4·H_2O.The neonatal piglets(n=45) were used to determine the relative organ weight, tissue iron contents and blood biochemical indices.Compared with the control, the relative weight of spleen and kidney were significantly increased(P < 0.05) in the Fe-Gly groups.The iron contents in liver,spleen, kidney and femur were also found increased(P < 0.05) in the Fe-Gly groups.The RBC(d 1 and 21),HGB(d 1 and 21) and HCT(d 1 and 21) in blood and Fn(d 1) and SI(d 1 and 21) significantly increased(P < 0.05), but the TIBC(d 1 and 21) in serum decreased(P < 0.05) in the Fe-Gly groups.Moreover, the kidney relative weight, iron content in liver, spleen, kidney and femur, RBC(d 1) and HGB(d 21) in blood, and SI(d 1)in the Fe-Gly groups increased(P < 0.05) compared with the FeSO_4·H_2O treatment.Linear and quadratic responses of the kidney relative weight, the iron content in liver, spleen, kidney and femur, RBC(d 1 and 21),HGB(d 1 and 21) and HCT(d 1 and 21) in whole blood, SI(d 1) and TIBC(d 1 and 21) in the Fe-Gly groups were observed(P < 0.05).Linear responses of Fn(d 1 and 21) and SI(d 21) in the Fe-Gly groups, and spleen relative weight, HCT(d 1), Fn(d 1) and TIBC(d 1 and 21) in the FeSO_4·H_2O groups were observed(P < 0.05).These finding suggest that Fe-Gly supplemented at the level of 110 mg/kg in the diet of sows in this experiment is superior to other forms of supplementation, based on HGB concentration, the relative organ weight, tissue iron contents and blood biochemical indices of piglets.Yan Li Weiren Yang Donghua Dong Shuzhen Jiang Zaibin Yang Yuxi Wang 2018Animal Nutrition2018,,2:11
7Exploiting Geo-Social Correlations to Improve Pairwise Ranking for Point-of-Interest Recommendation显示文摘Recently, as location-based social network(LBSN) rapidly grow, point-of-interest(POI) recommendation has become an important way to help people locate interesting places. Nowadays, there have been deep studies conducted on the geographical and social influence in the point-of-interest recommendation model based on the rating prediction. The fact is, however, relying solely on the rating fails to reflect the user's preferences very accurately, because the users are most concerned with the list of ranked point-of-interests(POIs) on the actual output of recommender systems. In this paper, we propose a co-pairwise ranking model called Geo-Social Bayesian Personalized Ranking model(GSBPR), which is based on the pairwise ranking with the exploiting geo-social correlations by incorporating the method of ranking learning into the process of POI recommendation. In this model, we develop a novel BPR pairwise ranking assumption by injecting users' geo-social preference. Based on this assumption, the POI recommendation model is reformulated by a three-level joint pairwise ranking model. And the experimental results based on real datasets show that the proposed method in this paper enjoys better recommendation performance compared to other state-of-the-art POI recommendation models.Rong Gao Jing Li Bo Du Xuefei Li Jun Chang Chengfang Song Donghua Liu 2018China Communications2018,15,7:9
8Development and validation of an endoscopic images-based deep learning model for detection with nasopharyngeal malignancies显示文摘Background:Due to the occult anatomic location of the nasopharynx and frequent presence of adenoid hyperpla-sia,the positive rate for malignancy identification during biopsy is low,thus leading to delayed or missed diagnosis for nasopharyngeal malignancies upon initial attempt.Here,we aimed to develop an artificial intelligence tool to detect nasopharyngeal malignancies under endoscopic examination based on deep learning.Methods:An endoscopic images-based nasopharyngeal malignancy detection model(eNPM-DM)consisting of a fully convolutional network based on the inception architecture was developed and fine-tuned using separate training and validation sets for both classification and segmentation.Briefly,a total of 28,966 qualified images were collected.Among these images,27,536 biopsy-proven images from 7951 individuals obtained from January 1st,2008,to December 31st,2016,were split into the training,validation and test sets at a ratio of 7:1:2 using simple randomiza-tion.Additionally,1430 images obtained from January 1st,2017,to March 31st,2017,were used as a prospective test set to compare the performance of the established model against oncologist evaluation.The dice similarity coef-ficient(DSC)was used to evaluate the efficiency of eNPM-DM in automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images,by comparing automatic segmentation with manual segmenta-tion performed by the experts.Results:All images were histopathologically confirmed,and included 5713(19.7%)normal control,19,107(66.0%)nasopharyngeal carcinoma(NPC),335(1.2%)NPC and 3811(13.2%)benign diseases.The eNPM-DM attained an overall accuracy of 88.7%(95%confidence interval(CI)87.8%-89.5%)in detecting malignancies in the test set.In the prospective comparison phase,eNPM-DM outperformed the experts:the overall accuracy was 88.0%(95%CI 86.1%-89.6%)vs.80.5%(95%CI 77.0%-84.0%).The eNPM-DM required less time(40 s vs.110.0±5.8 min)and exhibited encouraging performance in automatic segmentation of nasopharyngeal malignant area from the background,with an average DSC of 0.78±0.24 and 0.75±0.26 in the test and prospective test sets,respectively.Conclusions:The eNPM-DM outperformed oncologist evaluation in diagnostic classification of nasopharyngeal mass into benign versus malignant,and realized automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images.Chaofeng Li Bingzhong Jing Liangru Ke Bin Li Weixiong Xia Caisheng He Chaonan Qian Chong Zhao Haiqiang Mai Mingyuan Chen Kajia Cao Haoyuan Mo Ling Guo Qiuyan Chen Linquan Tang Wenze Qiu Yahui Yu Hu Liang Xinjun Huang Guoying Liu Wangzhong Li Lin Wang Rui Sun Xiong Zou Shanshan Guo Peiyu Huang Donghua Luo Fang Qiu Yishan Wu Yijun Hua Kuiyuan Liu Shuhui Lv Jingjing Miao Yanqun Xiang Ying Sun Xiang Guo Xing Lv 2018Cancer Communications2018,38,1:9

11Lichong decoction inhibits micro-angiogenesis by reducing the expressions of hypoxia inducible factor-1αand vascular endothelial growth factor in hysteromyoma mouse model显示文摘OBJECTIVE:To investigate the efficacy of Lichong decoction(LD)from Traditional Chinese Medicine,on micro-angiogenesis in a mouse model of hysteromyoma.METHODS:A mouse model of hysteromyoma was developed by orthotopic intrauterine injection of primary human myoma cells isolated from patients from the Beijing Obstetrics and Gynecology Hospital into CB-17 Scid mice.Mice were administered high-dose LD,low-dose LD,mifepristone or water(control)daily by gavage for 4 weeks.Uterine diameter and coefficient(uterine weight/body weight)were measured.Uterine morphology was assessed by light microscopy(hematoxylin and eosin)and transmission electron microscopy.Serum levels of estradiol,progesterone,follicle-stimulating hormone and luteinizing hormone(LH)were measured by enzyme-linked immunosorbent assay.Uterine protein expression of hypoxia inducible factor(HIF)-1α,CD31 and proliferating cell nuclear antigen(PCNA)was detected by immunohistochemistry.VEGF and HIF-1αm RNAs were quantified by RT-PCR.RESULTS:High-dose LD,low-dose LD and mifepristone reduced uterine diameter and coefficient,and attenuated the morphologic abnormalities associated with hysteromyoma.High-dose LD,low-dose LD and mifepristone inhibited hysteromyoma-induced micro-angiogenesis,as evidenced by a decrease in the number of new microvessels co-immunostaining for CD31 and PCNA(P<0.01).High-dose LD and mifepristone lowered serum levels of estradiol,progesterone and LH(P<0.05).High-dose LD,low-dose LD and mifepristone down-regulated HIF-1αm RNA and protein expressions and VEGF m RNA expression(P<0.01).CONCLUSION:The inhibition of hysteromyoma by LD may involve reductions in HIF-1αand VEGF expression and suppression of micro-angiogenesis.Wang Wenna Zhang Wufang Li Donghua Qian Ruiya Zhu Lijuan Liu Yu Chen Chao 2020Journal of Traditional Chinese Medicine2020,40,6:6
12Freeform OST-HMD system with large exit pupil diameter and vision correction capability显示文摘Compactness and light weight,large exit pupil diameter and distance,small distortion for virtual image,and see-through light paths are pivotal factors to achieve a better,wearable experience of optical see-through headmounted displays(OST-HMDs).In addition,light efficiency of the virtual image light path is an important factor for heat dissipation in HMD devices.This paper presents a new type of OST-HMD optical system that includes three wedge-shaped freeform prisms and two symmetric lenses.Based on a 0.71 in.microdisplay,an OST-HMD prototype with a diagonal field of view(FOV)of 45.3°,an F-number(F/#)of 1.8,an exit pupil size of 12 mm×8 mm,and an eye relief of 18 mm is demonstrated.The maximum value of distortion of the final system is 0.6%and 0.4%for virtual image and see-through light path,respectively.The overall dimension of the optical system per eye is no larger than 30 mm(width)×40 mm(height)×14 mm(thickness),and the weight of the optical module including lenses,holder,and microdisplay is 12.8 g.The light efficiency of the virtual image light path is up to 50%higher than those of other OST-HMD optical solutions.DEWEN CHENG JIAXI DUAN HAILONG CHEN HE WANG DANYANG LI QIWEI WANG QICHAO HOU TONG YANG WEIHONG HOU DONGHUA WANG XIAOYU CHI BIN JIANG YONGTIAN WANG 2022Photonics Research2022,10,1:5
13Pollution level and human health risk assessment of some pesticides and polychlorinated biphenyls in Nantong of Southeast China显示文摘Food consumption is one of the key exposure routes of humans to contaminants.This article evaluated the residue levels of 51 pesticides and 16 polychlorinated biphenyls(PCBs) in selected fish and food items which were commonly consumed in the Nantong area of Jiangsu Province,Southeast China.The 51 pesticides and 16 PCBs were analyzed by highly sensitive gas chromatographytandem mass spectrometry(GC-MS/MS).The results showed that organochlorine pesticides such as dichlorodiphenyltrichloroethanes(DDTs),hexachlorocyclohexanes(HCHs),hexachlorobenzene(HCB) and mirex and other pesticides including chlorpyrifos,pyrethroid pesticides,metolachlor,pyridaben and trifluralin were frequently detected in the samples,which was consistent with the accumulation level and characteristics of these toxic chemicals in human adipose tissue of people living in Nantong.Meanwhile,correlation of the residue level of toxic chemicals with their physical chemical properties and historic use pattern in Nantong area was observed.Combined with dietary survey results at the same sampling locations,human health risk assessment of ingestion through the dietary route was performed.The results suggested that the non-cancer risks of the chemicals investigated can be considered negligible in the Nantong area,however,the cancer risks from lifetime dietary exposure to DDTs and HCB have exceeded the acceptable levels.Na Wang Li Yi Lili Shi Deyang Kong Daoji Cai Donghua Wang Zhengjun Shan 2012Journal of Environmental Sciences2012,24,10:5
14Macroeconomic control,political costs and earnings management:Evidence from Chinese listed real estate companies显示文摘Firms in China have faced high political costs during China's economic transition,because they are affected by macroeconomic policies.However,research to date has offered no consistent conclusions on the relationship between political costs and earnings management in China.This study tests whether real estate firms attempt to decrease earnings during periods of macroeconomic control,using variables related to the national real estate market as proxies for political costs.We find that political costs are negatively related to earnings management in listed real estate firms.In addition,we find that non-state-owned enterprises utilized more income-decreasing accruals during this period.Our results are consistent with the political costs hypothesis.Donghua Chen Jieying Li Shangkun Liang Guojun Wang 2011China Journal of Accounting Research2011,,3:5
15Evaluation of angiosome-targeted infrapopliteal endovascular revascularization in critical diabetic limb ischemia显示文摘Objective To evaluate the rates of wound healing and limb preservation following angiosome-targeted infrapopliteal endovascular revascularization in the treatment of diabetic limb ischemia. Methods We performed a retrospective analysis of data gathered from 102 infrapopliteal angioplasty cases(60 males and 42 females; mean age, 72 ± 11 years) with Fontaine IV ischemia(ankle-brachial index, ABI: 0.16 ± 0.06). Forty-seven angioplasties were performed based on the angiosome concept(direct revascularization, DR), while 55 did not incorporate the angiosome concept(indirect revascularization, IR). The curative effects of angioplasty were assessed by postoperative determinations of ABI performed every 3 months during clinical follow-up visits conducted to assess healing of the ischemic wound. Amputation and death events were recorded throughout the study. Results All 102 patients were successfully revascularized without complications, and during a mean follow-up period of 18 ± 11 months, the mean postoperative ABI improved to 0.84 ± 0.10. The postoperative 6 and 12 month healing rates in the DR group were 85.1% and 93.5%, respectively, while the limb-salvage rates were 100% and 93.5%, respectively. The postoperative 6 and 12 month healing rates in the IR group were 60% and 76.4%, respectively, while the limb-salvage rates were 90.1%, and 85.5%, respectively. Conclusion Angiosome-based Infrapopliteal angioplasty was associated with better wound healing and higher rates of limb salvage in cases of critical diabetic foot ischemia. Revascularization should be provided to patients who have undergone indirect perfusion of the ischemic angiosome, as acceptable rates of limb salvage are obtained.Donghua Ji Tao Zhang Cheng Li Yongsheng Liu Feng Wang 2018Journal of Interventional Medicine2018,1,3:4

17The epigallocatechin gallate derivative Y_6 reverses drug resistance mediated by the ABCB1 transporter both in vitro and in vivo显示文摘Previously, we reported that Y_6, a new epigallocatechin gallate derivative, is efficacious in reversing doxorubicin(DOX)–mediated resistance in hepatocellular carcinoma BEL-7404/DOX cells. In this study, we evaluated the efficacy of Y_6 in reversing drug resistance both in vitro and in vivo by determining its effect on the adenosine triphosphate-binding cassette protein B1 transporter(ABCB1 or P-glycoprotein, P-gp). Our results showed that Y_6 significantly sensitized cells overexpressing the ABCB1 transporter to anticancer drugs that are ABCB1 substrates. Y_6 significantly stimulated the adenosine triphosphatase activity of ABCB1. Furthermore, Y_6 exhibited a higher docking score as compared with epigallocatechin gallate inside the transmembrane domain of ABCB1. In addition, in the nude mousetumor xenograft model, Y_6(110 mg/kg, intragastric administration), in combination with doxorubicin(2 mg/kg, intraperitoneal injection), significantly inhibited the growth of BEL-7404/DOX cell xenograft tumors, compared to equivalent epigallocatechin gallate. In conclusion, Y_6 significantly reversed ABCB1-mediated multidrug resistance and its mechanisms of action may result from its competitive inhibition of the ABCB1 drug efflux function.Yan Wen Ruiqiang Zhao Pranav Gupta Yingfang Fan Yunkai Zhang Zhenguang Huang Xiaohui Li Yuangang Su Lijuan Liao Yu-An Xie Donghua Yang Zhe-Sheng Chen Gang Liang 2019Acta Pharmaceutica Sinica B2019,9,2:3

20Eutrophication Evaluation of Water Body at Huailai Section of the Yongding River显示文摘In order to understand the water pollution characteristics in Huailai section of the Yongding River,the monitoring from November of 2016 to October of 2017 was conducted. 6 sampling points were selected for monitoring 6 indicators,and the temporal-spatial variation characteristics of nitrogen and phosphorus in the river were explored. Moreover,the ratio of nitrogen to phosphorus and an exponential universal formula of power function in logarithmic form were used to analyze temporal-spatial variation rules of nitrogen and phosphorus in water,assess the degree of eutrophication,and analyze eutrophication risk. The results showed that water pollution in Huailai section of the Yongding River was more serious. TN was13. 25 times of concentration limit of class III water in the dividing of surface water environment function area in the ' 13 thFive-year' Development Planning' of National Environmental Protection Standard. ON and NO-3-N were the main forms of TN,while mean value of TP was 0. 64 mg/L,and each index had the characteristics of agricultural non-point source pollution. The temporal-spatial distribution characteristics of nitrogen and phosphorus in the water body was obvious. At the time scale,the concentrations of nitrogen and phosphorus in the water body showed seasonal variation; at the space scale,the distribution of nitrogen and phosphorus in the water body was similar. The annual average ratio of nitrogen and phosphorus in Huailai section of the Yongding River was 32. 78,and the phytoplankton was in the overall state of phosphorus limitation. During the flat water period,phosphorus was the limiting nutrient element,and the ratio of nitrogen and phosphorus in the dry period and the abundant water period was suitable for the growth and reproduction of algae. The temporal-spatial variation of water body in Huailai section of the Yongding River was mostly in the ' eutrophication' stage. The maximum EI value was 228. 11 in dry season,and the lowest was 213. 06 in flood season,while it was218. 30 in flat water period. The fluvial dynamics process in Huailai section of the Yongding River was good,and the flow pattern of the river was continuous. The flow velocity of the main stream was 0. 43-1. 45 m/s,which was much larger than that of the algal bloom. The risk of cyanobacteria blooms in the main stream was low.Zhao Jianguo Li Hongbo Liu Cunqi Li Xiaoyu Chen Xinyong Yan Donghua Luo Ning 2018Meteorological and Environmental Research2018,9,6:3
