| 6 | Reactive capillary hemangiomas: a novel dermatologic toxicity following anti-PD-1 treatment with SHR-1210显示文摘Objective: SHR-1210 is a new and promising anti-PD-1 agent for solid tumors. During the phase I study of SHR-1210, we encountered a novel but prevalent immune-related dermatologic toxicity: reactive capillary hemangiomas(RCHs). Thus we tried to summarize the features of RCHs and estimate their relationship with tumor response.Methods: This prospective observational study systematically enrolled 98 patients with advanced solid tumors from April 27th,2016 to June 8th, 2017 in the context of the phase I clinical study of SHR-1210. This report focused on the skin toxicities. Patients underwent entire skin inspection every two weeks while taking medication. The clinical course of RCHs was recorded and their association with tumor response was estimated. The data cut-off date was November 15th, 2017.Results: After a median follow-up of 242(range, 29–567) days, RCHs were observed in 85.7%(84/98) of patients on cutaneous/mucosal surfaces; 84.5%(71/84) of the RCHs were evaluated as grade 1 adverse events. No grade 3 or 4 RCHs were observed. The time of onset of RCHs was dose dependent and shortest in the 400 mg-dose cohort(P < 0.001). Spontaneous and complete regression of RCHs was observed both during and after treatment. The objective response rate of tumors for patients with RCHs was 28.9%(24/83). However, no responders were observed among the patients without RCHs.Conclusions: RCHs were prevalent but manageable during treatment with SHR-1210. It might add to the expanding literature regarding immune-related dermatologic adverse events. | Xuelian Chen Lanying Ma Xi Wang Hongnan Mo Dawei Wu Bo Lan Dong Qu Hongtu Zhang Jing Huang Binghe Xu | 2019 | Cancer Biology & Medicine2019,16,1: | 53 |

| 9 | Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants. | Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He | 2021 | National Science Review2021,8,2: | 47 |
| 10 | Molecular cloning and functional characterization of a DREB1/CBF-like gene (GhDREB1L) from cotton显示文摘The transcription factors DREB1s/CBFs play important roles in the regulation of plant resistance to environmental stresses and are quite useful for generating transgenic plants tolerant to these stresses. In the present work, a cDNA encoding DREB1/CBF-like protein (GhDREB1L) from cotton was isolated, and its sequence features, DNA binding preference, and expression patterns of the transcripts were also characterized. GhDREB1L contained one conserved AP2/ERF domain and its amino acid sequence was similar to the DREB1/CBF group of the DREB family from other plants. The DNA-binding domain of GhDREB1L was successfully expressed as a fusion protein in Escherichia coli BL21 (DE3) and purified by Ni-NTA affinity chromatography. Electrophoretic mobility shift assay revealed that the purified GhDREB1L fusion protein had a specific binding activity with the previously characterized DRE ele-ment (core sequence, ACCGAC) and also with the DRE-like sequence (core sequence, GCCGAC) in the promoter of the dehydration-responsive late embryogenesis-abundant gene LEA D113. Semi-quantita- tive RT-PCR showed that GhDREB1L was induced in the cotton cotyledons by low temperature, as well as drought and NaCl treatments. These results suggested that the novel cotton GhDREB1L might play an important role in response to low temperature as well as drought and high salinity through binding to the DRE cis-element. | HUANG Bo, JIN LongGuo & LIU JinYuan Laboratory of Molecular Biology and Protein Science Laboratory of the Ministry of Education, Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing 100084, China | 2007 | Science China(Life Sciences)2007,50,1: | 35 |
| 11 | 42,573 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 | 2018 | Science China(Life Sciences)2018,61,6: | 39 |
| 12 | Review of risk factors for human echinococcosis prevalence on the Qinghai-Tibet Plateau, China: a prospective for control options显示文摘Objective: Echinococcosis is a major parasitic zoonosis of public health importance in western China. In 2004, the Chinese Ministry of Health estimated that 380,000 people had the disease in the region. The Qinghai-Tibet Plateau is highly co-endemic with both alveolar echinococcosis (AE) and cystic echinococcosis (CE). In the past years, the Chinese government has been increasing the financial support to control the diseases in this region. Therefore, it is very important to identify the significant risk factors of the diseases by reviewing studies done in the region in the past decade to help policymakers design appropriate control strategies. Review: Selection criteria for which literature to review were firstly defined. Medline, CNKI (China National Knowledge Infrastructure), and Google Scholar were systematically searched for literature published between January 2000 and July 2011. Significant risk factors found by single factor and/or multiple factors analysis were listed, counted, and summarized. Literature was examined to check the comparability of the data;age and sex specific prevalence with same data structures were merged and used for further analysis. A variety of assumed social, economical, behavioral, and ecological risk factors were studied on the Plateau. Those most at risk were Tibetan herdsmen, the old and female in particular. By analyzing merged comparable data, it was found that females had a significant higher prevalence, and a positive linearity relationship existed between echinococcosis prevalence and increasing age. In terms of behavioral risk factors, playing with dogs was mostly correlated with CE and/or AE prevalence. In terms of hygiene, employing ground water as the drinking water source was significantly correlated with CE and AE prevalence. For definitive hosts, dog related factors were most frequently identified with prevalence of CE or/and AE;fox was a potential risk factor for AE prevalence only. Overgrazing and deforestation were significant for AE prevalence only. Conclusion: Tibetan herdsmen communities were at the highest risk of echinococcosis prevalence and should be the focus of echinococcosis control. Deworming both owned and stray dogs should be a major measure for controlling echinococcosis;treatment of wild definitive hosts should also be considered for AE endemic areas. Health education activities should be in concert with the local people's education backgrounds and languages in order to be able to improve behaviors. Further researches are needed to clarify the importance of wild hosts for AE/CE prevalence, the extent and range of the impacts of ecologic changes (overgrazing and deforestation) on the AE prevalence, and risk factors in Tibet. | Qian Wang Yan Huang Liang Huang Wenjie Yu Wei He Bo Zhong Wei Li Xiangman Zeng Dominique A Vuitton Patrick Giraudoux Philip S Craig Weiping Wu | 2014 | Infectious Diseases of Poverty2014,3,1: | 35 |
| 13 | Phase II clinical trial using camrelizumab combined with apatinib and chemotherapy as the first-line treatment of advanced esophageal squamous cell carcinoma显示文摘Background:Effective therapeutic options are limited for patients with advanced esophageal squamous cell carcinoma(ESCC).The incorporation of an immune checkpoint inhibitor and a molecular anti-angiogenic agent into the commonly adopted chemotherapy may produce synergistic effects.Therefore,we aimed to investigate the efficacy and safety of camrelizumab plus apatinib combined with chemotherapy as the first-line treatment of advanced ESCC.Methods:In this single-arm prospective phase II trial,patients with unresectable locally advanced or recurrent/metastatic ESCC received camrelizumab 200 mg,liposomal paclitaxel 150 mg/m2,and nedaplatin 50 mg/m2 on day 1,and apatinib 250 mg on days 1-14.The treatments were repeated every 14 days for up to 9 cycles,followed by maintenance therapy with camrelizumab and apatinib.The primary endpoint was objective response rate(ORR)according to the Response Evaluation Criteria in Solid Tumors(version 1.1).Secondary endpoints included disease control rate(DCR),progression-free survival(PFS),overall survival(OS),and safety.Results:We enrolled 30 patients between August 7,2018 and February 23,2019.The median follow-up was 24.98 months(95%confidence interval[CI]:23.05-26.16 months).The centrally assessed ORR was 80.0%(95%CI:61.4%-92.3%),with a median duration of response of 9.77 months(range:1.54 to 24.82+months).The DCR reached 96.7%(95%CI:82.8%-99.9%).The median PFS was 6.85 months(95%CI:4.46-14.20 months),and the median OS was 19.43 months(95%CI:9.93 months–not reached).The most common grade 3-4 treatmentrelated adverse events(AEs)were leukopenia(83.3%),neutropenia(60.0%),and increased aspartate aminotransferase level(26.7%).Treatment-related serious AEs included febrile neutropenia,leukopenia,and anorexia in one patient(3.3%),and single cases of increased blood bilirubin level(3.3%)and toxic epidermal necrolysis(3.3%).No treatment-related deaths occurred.Conclusions:Camrelizumab plus apatinib combined with liposomal paclitaxel and nedaplatin as first-line treatment demonstrated feasible anti-tumor activity and manageable safety in patients with advanced ESCC.Randomized trials to evaluate this new combination strategy are warranted.Trial registration:This trial was registered on July 27,2018,at ClinicalTrials.gov(identifier:NCT03603756). | Bo Zhang Ling Qi Xi Wang Jianping Xu Yun Liu Lan Mu Xingyuan Wang Lidan Bai Jing Huang | 2020 | Cancer Communications2020,40,12: | 38 |
| 14 | Baicalin prevents LPS-induced activation of TLR4/NF-κB p65 pathway and inflammation in mice via inhibiting the expression of CD14显示文摘Previous studies have shown that baicalin,an active ingredient of the Chinese traditional medicine Huangqin,attenuates LPS-induced inflammation by inhibiting the activation of TLR4/NF-κBp65 pathway,but how it affects this pathway is unknown.It has been shown that CD14 binds directly to LPS and plays an important role in sensitizing the cells to minute quantities of LPS via chaperoning LPS molecules to the TLR4/MD-2 signaling complex.In the present study we investigated the role of CD14 in the anti-inflammatory effects of baicalin in vitro and in vivo.Exposure to LPS(1μg/mL)induced inflammatory responses in RAW264.7 cells,evidenced by marked increases in the expression of MHC II molecules and the secretion of NO and IL-6,and by activation of MyD88/NF-κB p65 signaling pathway,as well as the expression of CD14 and TLR4.These changes were dose-dependently attenuated by pretreatment baicalin(12.5–50μM),but not by baicalin post-treatment.In RAW264.7 cells without LPS stimulation,baicalin dose-dependently inhibit the protein and mRNA expression of CD14,but not TLR4.In RAW264.7 cells with CD14 knockdown,baicalin pretreatment did not prevent inflammatory responses and activation of MyD88/NF-κB p65 pathway induced by high concentrations(1000μg/mL)of LPS.Furthermore,baicalin pretreatment also inhibited the expression of CD14 and activation of MyD88/NF-κB p65 pathway in LPS-induced hepatocyte-derived HepG2 cells and intestinal epithelial-derived HT-29 cells.In mice with intraperitoneal injection of LPS and in DSS-induced UC mice,oral administration of baicalin exerted protective effects by inhibition of CD14 expression and inflammation.Taken together,we demonstrate that baicalin pretreatment prevents LPS-induced inflammation in RAW264.7 cells in CD14-dependent manner.This study supports the therapeutic use of baicalin in preventing the progression of LPS-induced inflammatory diseases. | Ya-jun Fu Bo Xu Shao-wei Huang Xia Luo Xiang-liang Deng Shuang Luo Chang Liu Qing Wang Jin-yan Chen Lian Zhou | 2021 | Acta Pharmacologica Sinica2021,42,1: | 31 |
| 15 | Precise orbit determination for geostationary satellites with multiple tracking techniques显示文摘A new precise orbit determination (POD) strategy based on the combination of satellite laser ranging (SLR) and C-band transfer ranging for geostationary satellites (GEO) is presented.Two approaches to calibrate ranging biases of the C-band ranging system are proposed,namely the two tracking system co-location comparison and the combined POD method,with calibration accuracies estimated to be 0.5 ns and 1 ns respectively.Using data from a C-band tracking network in China,POD experiments indicate that meter-level POD accuracy is achievable for GEO.Root-mean-square (RMS) of the post-fit C-band ranging data is about 0.205 m.The radial component errors of POD are evaluated with SLR data from a station in Beijing,with residual RMS of 0.133 m.Orbital overlapping experiments show the total orbit error is a few meters.Computations of SLR residuals also suggest that for 2-hour prediction,the predicted radial error is about 0.373 m. | GUO Rui HU XiaoGong TANG Bo HUANG Yong LIU Li CHENG LiuCheng HE Feng | 2010 | Chinese Science Bulletin2010,55,8: | 24 |

| 17 | Breast cancer development and progression:Risk factors,cancer stem cells,signaling pathways,genomics,and molecular pathogenesis显示文摘As the most commonly occurring cancer in women worldwide,breast cancer poses a formidable public health challenge on a global scale.Breast cancer consists of a group of biologically and molecularly heterogeneous diseases originated from the breast.While the risk factors associated with this cancer varies with respect to other cancers,genetic predisposition,most notably mutations in BRCA1 or BRCA2 gene,is an important causative factor for this malignancy.Breast cancers can begin in different areas of the breast,such as the ducts,the lobules,or the tissue in between.Within the large group of diverse breast carcinomas,there are various denoted types of breast cancer based on their invasiveness relative to the primary tumor sites.It is important to distinguish between the various subtypes because they have different prognoses and treatment implications.As there are remarkable parallels between normal development and breast cancer progression at the molecular level,it has been postulated that breast cancer may be derived from mammary cancer stem cells.Normal breast development and mammary stem cells are regulated by several signaling pathways,such as estrogen receptors(ERs),HER2,and Wnt/b-catenin signaling pathways,which control stem cell proliferation,cell death,cell differentiation,and cell motility.Furthermore,emerging evidence indicates that epigenetic regulations and noncoding RNAs may play important roles in breast cancer development and may contribute to the heterogeneity and metastatic aspects of breast cancer,especially for triple-negative breast cancer.This review provides a comprehensive survey of the molecular,cellular and genetic aspects of breast cancer. | Yixiao Feng Mia Spezia Shifeng Huang Chengfu Yuan Zongyue Zeng Linghuan Zhang Xiaojuan Ji Wei Liu Bo Huang Wenping Luo Bo Liu Yan Lei Scott Du Akhila Vuppalapati Hue H.Luu Rex C.Haydon Tong-Chuan He Guosheng Ren | 2018 | Genes & Diseases2018,5,2: | 24 |
| 18 | Effect of N Fertilizers on Root Growth and Endogenous Hormones in Strawberry显示文摘Endogenous hormones play an important role in the growth and development of roots. The objective of this research was to study the effect of four types of N fertilizers on the root growth of strawberry (Fragaria ananassa Duchesne) and the endogenous enzymes of indole-3-acetic acid (IAA), abscisic acid (ABA), and isopentenyl adenosine (iPA) in its roots and leaves using enzyme-linked immunosorbent assay. Application of all types of N fertilizers significantly depressed (P ≤ 0.05) root growth at 20 d after transplanting. Application of organic-inorganic fertilizer (OIF) as basal fertilizer had a significant negative effect (P ≤ 0.05) on root growth. The application of OIF and urea lowered the lateral root frequency in strawberry plants at 60 d (P ≤ 0.05) compared with the application of two organic fertilizers (OFA and OFB) and the control (CK). With the fertilizer treatments, there were the same concentrations of IAA and ABA in both roots and leaves at the initial growth stage (20 d), lower levels of IAA and ABA at the later stage (60 d), and higher iPA levels at all seedling stages as compared to those of CK. Thus, changes in the concentrations of endogenous phytohormones in strawberry plants could be responsible for the morphological changes of roots due to fertilization. | WANG Bo LAI Tao HUANG Qi-Wei YANG Xing-Ming SHEN Qi-Rong | 2009 | Pedosphere2009,19,1: | 22 |
| 19 | Occurrence and Fate of Antibiotics in the Aqueous Environment and Their Removal by Constructed Wetlands in China: A review显示文摘Overuse of antibiotics has become a serious ecological problem worldwide.There is growing concern that antibiotics are losing their effectiveness due to an increased antibiotic resistance in bacteria.During the last twenty years,consumption of antibiotics has increased rapidly in China,which has been cited as one of the world's worst abusers of antibiotics.This review summarizes the current state of antibiotic contamination in China's three major rivers(the Yangtze River,Yellow River,and Pearl River) and illustrates the occurrence and fate of antibiotics in conventional municipal wastewater treatment plants(WWTPs).The analytical data indicate that traditional WWTPs cannot completely remove these concerned pharmaceuticals,as seen in the large difference between the distribution coefficient(K_d) and the uneven removal efficiency of various types of antibiotics.Although constructed wetlands(CWs)offer a potential way to remove these antibiotics from water supplies,knowledge of their mechanisms is limited.There are four main factors affecting the performance of CWs used for the treatment of antibiotics in water supplies,the types and configurations of CWs,hydraulic load rates,substrates,and plants and microorganisms.Further researches focusing on these factors are needed to improve the removal efficiency of antibiotics in CWs. | GUAN Yidong WANG Bo GAO Yongxia LIU Wen ZHAO Xiaoli HUANG Xiaofeng YU Jianghuai | 2017 | Pedosphere2017,27,1: | 22 |
| 20 | Activation of aldehyde dehydrogenase 2 slows down the progression of atherosclerosis via attenuation of ER stress and apoptosis in smooth muscle cells显示文摘(ALDH2 ) 醛脱氢酶 2 是在醛的新陈代谢的关键 mitochondrial 酶并且可以为象心脏的肥大,心失败,心肌的 I/R 损害,灌注,心律不齐,冠的心疾病和动脉粥样硬化那样的条件有有益的心血管的效果。在这研究,我们在动脉粥样硬化和内在的机制的前进调查了 ALDH2 的角色,与 endoplasmic 蜂窝胃的一个焦点(嗯) 应力。临床的研究与冠的心疾病在 248 个病人被执行。病人根据他们的 ALDH2 遗传型被划分成二个组。基线临床的特征和冠的 angiography 被记录,并且冠的动脉 Gensini 分数是计算的。4-hydroxy-2-nonenal (4-HNE ) 的浆液层次被检测。临床的学习表明变异的 ALDH2 遗传型是为冠的心疾病的一个独立风险因素。ALDH2 基因多型性仔细与动脉粥样硬化和冠的动脉狭窄的严厉被联系。4-HNE 的浆液层次比在有野类型的 ALDH2 遗传型的病人在有变异的 ALDH2 遗传型的病人是显著地更高的。作为一在里面动脉粥样硬化的 vitro 模型,老鼠光滑的肌肉房间( SMC )与 oxygenized 被对待低密度的脂蛋白( ox-LDL )它显著地提高了层次嗯标记调整葡萄糖的 protein78 ( GRP78 ),蛋白质 kinase 象R一样嗯 kinase (津贴), phosphorylated 真核细胞的翻译开始因素子单元( p-eIF2 ),激活的抄写 factor-4 ( ATF-4 ), CEBP 相应蛋白质(砍)和在房间的 4-HNE 。所有 ox-LDL-induced 回答显著地面对 Alda-1 (激活代理人的 ALDH2 ) 被稀释,并且面对 daidzin (一个 ALDH2 禁止者) 加重了。而且,有 ALDH2 使活跃之物 Alda-1 的预告的处理显著地减少了 ox-LDL-induced apoptosis。同样, ALDH2 的 overexpression 保护了 SMC 免于 ox-LDL-induced 嗯应力象一样嗯导致压力的 apoptosis。这些调查结果建议 ALDH2 可以经由变细减缓动脉粥样硬化的前进嗯在光滑的肌肉房间的应力和 apoptosis。 | Mei-yan YANG Ya-bin WANG Bo HAN Bo YANG Yu-wei QIANG Yan ZHANG Zhao WANG Xu HUANG Jie LIU Yun-dai CHEN Jun REN Feng CAO Yong XU | 2018 | Acta Pharmacologica Sinica2018,39,1: | 22 |
