| 1 | Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups. | YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng | 2016 | Biomedical and Environmental Sciences2016，29，3： | 18 |
| 2 | Expression of calreticulin is associated with infiltration of T-cells in stage ⅢB colon cancer显示文摘AIM: To investigate the correlation between expression of calreticulin and infiltration of lymphocytes in stage ⅢB colon cancer. METHODS: Sixty-eight pathologically-confirmed speci-mens were obtained from stage ⅢB (T3N1M0) colon cancer patients who underwent radical resection between January 1999 and May 2002 at the Cancer Center of Sun Yat-Sen University, Guangzhou, China. Immuno-histochemical analysis was performed to show infiltration of lymphocytes and expression of calreticulin in colon cancer. Association between calreticulin expression, infiltration of lymphocytes, and 5-year survival rate of patients was assessed. RESULTS: The expression level of calreticulin was lower in cancer nest than in its adjacent normal epithelium since 61.8% (42/68) of the samples were stained with calreticulin in colon cancer. The expression of calreticulin in colon cancer was associated with the infi ltration of CD45RO+ cells rather than with that of CD3+ cells. In addition, the stronger expression of calreticulin and the higher infiltration of CD3+ and CD45RO+ cells in colon cancer were associated with the higher 5-year survival rate of patients. CONCLUSION: Expression of calreticulin is associated with infiltration of T-cells, which implies that a low expression level of molecular marker may represent a new mechanism underlying immune escape in colon cancer. | Rui-Qing Peng, Ya Ding, Xing Zhang, Yi-Xin Zeng, Xiao- Shi Zhang, State Key Laboratory of Oncology in South China, Biotherapy Center, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China Ying-Bo Chen, Zhi-Wei Zhou, State Key Laboratory of Oncology in South China, Department of Gastric and Pancreatic Oncology, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China Rong Zhang, State Key Laboratory of Oncology in South China, Department of Endoscopy, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China Xing-Juan Yu, Yi-Xin Zeng, State Key Laboratory of Oncology in South China, Department of Experimental Research, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China | 2010 | World Journal of Gastroenterology2010，16，19： | 16 |

| 4 | Anti-HBV effect of TAT-HBV targeted ribonuclease显示文摘AIM: To prepare and purify TAT-HBV targeted ribonuclease fusion protein, evaluate its transduction activity and investigate its effect on HBV replication in 2.2.15 cells.METHODS: The prokaryotic expression vector pTAT containing TR gene was used in transforming E. coli BL21(DE3) LysS and TR was expressed with the induction of IPTG. The TAT-TR fusion protein was purified using Ni-NTA-agrose and PD-10 desalting columns, and analyzed by SDSPAGE. Transduction efficiency of TAT-TR was detected with immunofluorescence assay and the concentration of HBeAg in the supernatant of the 2.2.15 cells was determined via solid-phase radioimmunoassay (spRIA). MTT assay was used to detect the cytotoxicity of TAT-TR.RESULTS: The SDS-PAGE showed that the TAT-TR fusion protein was purified successfully, and the purity of TAT-TR was 90 %. The visualization of TAT-TR by immunofiuorescence assay indicated its high efficiency in transducing 2.2.15 cells.RIA result suggests that TAT-TR could inhibit the replication of HBV effectively, it didn′t affect cell growth and had no cytotoxicity.CONCLUSION: TAT-TR possesses a significant anti-HBV activity and the preparation of TAT-TR fusion protein has laid the foundation for the use of TR in the therapeutic trial of HBV infection. | Jin Ding Jun Liu Cai-Fang Xue Wei-Dong Gong Ying-Hui Li Ya Zhao Department of Etiology,Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China | 2003 | World Journal of Gastroenterology2003，9，7： | 12 |
| 5 | Chloroquine enhances the cytotoxicity of topotecan by inhibiting autophagy in lung cancer cells显示文摘Although the anti-malaria drug chloroquine(CQ) has been shown to enhance chemotherapy and radiation sensitivity in clinical trials,the potential mechanisms underlying this enhancement are still unclear.Here,we examined the relevant mechanisms by which the multipotent CQ enhanced the cytotoxicity of topotecan(TPT).The lung cancer cell line A549 was treated with TPT alone or TPT combined with CQ at non-cytotoxic concentrations.Cell viability was assessed using the MTT assay.The percentage of apoptotic cells and the presence of a side population of cells were both determined by flow cytometry.Autophagy and the expression of Bcl-2 family proteins were examined by Western blotting.The accumulation of YFP-LC3 dots and the formation of acidic vesicular organelles were examined by confocal microscopy.CQ sensitized A549 cells to TPT and enhanced TPT-induced apoptosis in a Bcl-2 family protein-independent fashion.CQ inhibited TPT-induced autophagy,which modified the cytotoxicity of TPT.However,CQ failed to modify the transfer of TPT across the cytoplasmic membrane and did not increase lysosomal permeability.This study showed that CQ at non-cytotoxic concentrations potentiated the cytotoxicity of TPT by interfering with autophagy,implying that CQ has significant potential as a chemotherapeutic enhancer. | Yao Wang Rui-Qing Peng Dan-Dan Li Ya Ding Xiao-Qi Wu Yi-Xin Zeng Xiao-Feng Zhu Xiao-Shi Zhang | 2011 | Chinese Journal of Cancer2011，30，10： | 11 |

| 7 | Pseudocapacitive materials for electrochemical capacitors:from rational synthesis to capacitance optimization显示文摘Among various energy-storage devices,electrochemical capacitors(ECs) are prominent power provision but show relatively low energy density.One way to increase the energy density of ECs is to move from carbon-based electric double-layer capacitors to pseudocapacitors,which manifest much higher capacitance.However,compared with carbon materials,the pseudocapacitive electrodes sufer from high resistance for electron and/or ion transfer,signiicantly restricting their capacity,rate capability and cyclability.Rational design of electrode materials ofers opportunities to optimize their electrochemical performance,leading to devices with high energy density while maintaining high power density.his paper reviews the diferent approaches of electrodes striving to advance the energy and power density of ECs. | Jie Wang Shengyang Dong Bing Ding Ya Wang Xiaodong Hao Hui Dou Yongyao Xia Xiaogang Zhang | 2017 | National Science Review2017，4，1： | 7 |
| 8 | Potential predictors for mental stress-induced myocardial ischemia in patients with coronary artery disease显示文摘Background: Mental stress-induced myocardial ischemia (MSIMI) is closely associated with adverse cardiac events in patients with coronary artery disease (CAD) and we aimed to determine whether biomarkers and blood pressure could be potential predictors of MSIMI. Methods: This study enrolled 82 patients with documented CAD between June 1, 2017 and November 9, 2017. Patient blood samples were obtained at resting period and at the end of mental arithmetic. Then, patients were assigned to MSIMI positive group and MSIMI negative group. The main statistical methods included linear regression, receiver operating characteristic (ROC) curves, and logistic regression. Results: Patients with CAD with MSIMI had significantly greater median resting N-terminal pro-brain natriuretic peptide (NT-proBNP, 141.02 [45.85–202.76] pg/mL vs. 57.95 [27.06–117.64] pg/mL;Z =-2.23, P = 0.03) and mean systolic blood pressure (SBP)(145.56 ± 16.87 mmHg vs. 134.92 ± 18.16 mmHg, Z =-2.13, P = 0.04) when compared with those without MSIMI. After 5-min mental stress task, those who developed MSIMI presented higher elevation of median post-stressor high sensitivity cardiac troponin I (hs-cTnI, 0.020 [0.009–0.100] ng/mL vs. 0.009 [0.009–0.010] ng/mL;Z =-2.45, P = 0.01), post-stressor NT-proBNP (138.96 [39.93–201.56] pg/mL vs. 61.55 [25.66–86.50] pg/mL;Z =-2.15, P = 0.03) compared with those without MSIMI. Using the ROC curves, and after the adjustment for basic characteristics, the multiple logistic regression analysis showed that patients presenting a post-stressor hs-cTnI ≥ 0.015 ng/mL had seven-fold increase in the risk of developing MSIMI (odds ratio [OR]: 7.09;95% confidence interval [CI]: 1.65–30.48;P = 0.009), a rest NT-proBNP ≥ 80.51 pg/mL had nearly eight-fold increase (OR: 7.85;95% CI: 1.51–40.82;P = 0.014), a post-stressor NT-proBNP ≥ 98.80 pg/mL had 35-fold increase (OR: 34.96;95% CI: 3.72– 328.50;P = 0.002), a rest SBP ≥ 129.50 mmHg had 11-fold increase (OR: 11.42;95% CI: 1.21–108.17;P = 0.034). Conclusions: The present study shows that CAD patients with higher hs-cTnI level, and/or greater NT-proBNP and/or SBP are at higher risk of suffering from MSIMI when compared with those without MSIMI, indicating that hs-cTnI, NT-proBNP, SBP might be potential predictors of MSIMI. | Mei-Yan Liu Ya Yang Li-Jun Zhang Li-Hong Pu Dong-Fang He Jian-Yang Liu Adam Hafeez Yu-Chuan Ding Huan Ma Qing-Shan Geng | 2019 | Chinese Medical Journal2019，，12： | 7 |

| 10 | The Lyman-alpha Solar Telescope(LST) for the ASO-S mission——Ⅱ. design of LST显示文摘As one of the three payloads for the Advanced Space-based Solar Observatory(ASO-S)mission,the Lyman-alpha(Lyα)Solar Telescope(LST)is composed of three instruments:a Solar Corona Imager(SCI),a LyαSolar Disk Imager(SDI)and a full-disk White-light Solar Telescope(WST).When working in-orbit,LST will simultaneously perform high-resolution imaging observations of all regions from the solar disk to the inner corona up to 2.5 R⊙(R⊙stands for the mean solar radius)with a spatial resolution of 4.8′′and 1.2′′for coronal and disk observations,respectively,and a temporal resolution of 30–120 s and 1–120 s for coronal and disk observations,respectively.The maximum exposure time can be up to20 s due to precise pointing and image stabilization function.Among the three telescopes of LST,SCI is a dual-waveband coronagraph simultaneously and independently observing the inner corona in the HI Lyα(121.6±10 nm)line and white light(WL)(700±40 nm)wavebands by using a narrowband Lyαbeam splitter and has a field of view(FOV)from 1.1 to 2.5 R⊙.The stray-light suppression level can attain<10^-6 B⊙(B⊙is the mean brightness of the solar disk)at 1.1 R⊙and≤5×10^-8 B⊙at 2.5 R⊙.SDI and WST are solar disk imagers working in the Lyαline and 360.0 nm wavebands,respectively,which adopt an off-axis two-mirror reflective structure with an FOV up to 1.2 R⊙,covering the inner coronal edge area and relating to coronal imaging.We present the up-to-date design for the LST payload. | Bo Chen Hui Li Ke-Fei Song Quan-Feng Guo Pei-Jie Zhang Ling-Ping He Shuang Dai Xiao-Dong Wang Hai-Feng Wang Chun-Long Liu Hong-Ji Zhang Guang Zhang Yunqi Wang Shi-Jie Liu Hong-Xin Zhang Lei Liu Shi-Lei Mao Yang Liu Jia-Hao Peng Peng Wang Liang Sun Yang Liu Zhen-Wei Han Yan-Long Wang Kun Wu Guang-Xing Ding Peng Zhou Xin Zheng Ming-Yi Xia Qing-Wen Wu Jin-Jiang Xie Ya Chen Shu-Mei Song Hong Wang Bo Zhu Chang-Bo Chu Wen-Gang Yang Li Feng Yu Huang Wei-Qun Gan Ying Li Jing-Wei Li Lei Lu Jian-Chao Xue Bei-Li Ying Ming-Zhe Sun Cheng Zhu Wei-Min Bao Lei Deng Zeng-Shan Yin | 2019 | Research in Astronomy and Astrophysics2019，19，11： | 6 |
| 11 | Inhibition of HBV targeted ribonuclease enhanced by introduction of linker显示文摘AIM: To construct human eosinophil-derived neurotoxin (hEDN) and HBV core protein (HBVc) eukaryotic fusion expression vector with a linker (Gly4 Ser)3 between them to optimize the molecule folding, which will be used to inhibit HBV replication in vitro.METHODS: Previously constructed pcDNA3. 1(-)/TR was used as a template. Linker sequence was synthesized and annealed to form dslinker, and cloned into pcDNA3.1(-)/TR to produce plasmid pcDNA3.1(-)/HBc-linker. Then the hEDN fragment was PCR amplified and inserted into pcDNA3.1(-)/HBc-linker to form pcDNA3.1(-)/TNL in which the effector molecule and the target molecule were separated by a linker sequence. pcDNA3.1(-)/TNL expression was identified by indirect immunofluorescence staining. Radioimmunoassay was used to analyse anti-HBV activity of pcDNA3.1(-)/TNL.Meanwhile, metabolism of cells was evaluated by NTT colorimetry.RESULTS: hEDN and HBVc eukaryotic fusion expression vector with a linker (Gly4Ser)3 between them was successfully constructed. pcDNA3.1(-)/TNL was expressed in HepG2.2.15 cells efficiently. A significant decrease of HBsAg concentration from pcDNA3.1(-)/TNL transfectant was observed compared to pcDNA3. 1(-)/TR (P=0.036, P<0.05).MTT assay suggested that there were no significant differences between groups (P=0.08, P>0.05).CONCLUSION: Linker introduction enhances the inhibitory effect of HBV targeted ribonuclease significantly. | Wei-Dong Gong Jun Liu Jin Ding Ya Zhao Ying-Hui Li Cai-Fang Xue Department of Pathogenic Organisms,Fourth Military Medical University,Xi’an 710033,Shaanxi Province,China | 2003 | World Journal of Gastroenterology2003，9，7： | 6 |

| 15 | Separation of chalcopyrite and pyrite from a copper tailing by ammonium humate显示文摘Copper tailings constitute a large proportion of mine wastes. Some of the copper tailings can be recycled to recover valuable minerals. In this paper, a copper tailing was studied through the chemical analysis method, Xray diffraction and scanning electron microscope-energy dispersive spectrum. It turned out that chalcopyrite(Cu) and pyrite(S) were the main recoverable minerals in the tailing. In order to separate chalcopyrite from pyrite in low pulp pH, ammonium humate(AH) was singled out as the effective regulator. The depression mechanism of AH on the flotation of pyrite was proved by FTIR spectrum and XPS spectrum, demonstrating that there was a chemical adsorption between AH and pyrite. By Response Surface Methodology(RSM), the interaction between AH, pulp pH and iso-butyl ethionine(Z200) was discussed. It was illustrated that the optimal dosage of AH was 1678 g·t^(-1) involving both the recovery of Cu and S. The point prediction by RSM and the closed-circuit flotation displayed that the qualified Cu concentrate and S concentrate could be obtained from the copper tailing.The study indicated that AH was a promising pyrite depressor in the low pulp pH from copper tailings. | Cuicui Lü Yongliang Wang Peng Qian Ya Liu Guoyan Fu Jian Ding Shufeng Ye Yuanfa Chen | 2018 | Chinese Journal of Chemical Engineering2018，26，9： | 5 |
| 16 | Di(2-ethylhexyl) phthalate Disorders Lipid Metabolism via TYK2/STAT1 and Autophagy in Rats显示文摘Objective Previous studies have indicated that the plasticizer di(2-ethylhexyl) phthalate(DEHP) affects lipid accumulation;however, its underlying mechanism remains unclear. We aim to clarify the effect of DEHP on lipid metabolism and the role of TYK2/STAT1 and autophagy. Methods In total, 160 Wistar rats were exposed to DEHP [0, 5, 50, 500 mg/(kg·d)] for 8 weeks. Lipid levels, as well as mRNA and protein levels of TYK2, STAT1, PPARγ, AOX, FAS, LPL, and LC3 were detected. Results The results indicate that DEHP exposure may lead to increased weight gain and altered serum lipids. We observed that DEHP exposure affected liver parenchyma and increased the volume or number of fat cells. In adipose tissue, decreased TYK2 and STAT1 promoted the expression of PPARγ and FAS. The mRNA and protein expression of LC3 in 50 and 500 mg/(kg·d) groups was increased significantly. In the liver, TYK2 and STAT1 increased compensatorily;however, the expression of FAS and AOX increased, while LPL expression decreased. Joint exposure to both a high-fat diet and DEHP led to complete disorder of lipid metabolism. Conclusion It is suggested that DEHP induces lipid metabolism disorder by regulating TYK2/STAT1. Autophagy may play a potential role in this process as well. High-fat diet, in combination with DEHP exposure, may jointly have an effect on lipid metabolism disorder. | ZHANG Yue Zhu ZHANG Zhao Ming ZHOU Li Ting ZHU Jian ZHANG Xiao Han QI Wen DING Shuang XU Qi HAN Xu ZHAO Ya Ming SONG Xin Yue ZHAO Tian Yang YE Lin | 2019 | Biomedical and Environmental Sciences2019，32，6： | 4 |

| 19 | Tetrandrine inhibits proliferation of colon cancer cells by BMP9/PTEN/PI3K/AKT signaling显示文摘Despite advances in screening and treatment,colon cancer remains one of the leading causes of cancer-related death.Finding novel and useful drug treatment targets is also an urgent need for clinical applications.Tetrandrine(Tet)is extracted from the Chinese medicinal herbal medicine,which is a well-known calcium blocker with a variety of pharmacological activities,including anti-cancer.In this study,we recruited cell viability assay,flow cytometry analysis,cloning formation to confirm that Tet can inhibit the proliferation of SW620 cells,and induce apoptosis.Mechanically,we confirmed that Tet up-regulates the mRNA and protein level of BMP9 in SW620 cells.Over-expression BMP9 enhances the anticancer effects of Tet in SW620 cells,but these effects can be partly reversed by silencing BMP9.Also,Tet reduces phosphorylation of Aktl/2/3 in SW620 cells,which could be elevated by overexpressed BMP9 and impaired by silencing BMP9.Furthermore,we demonstrated that Tet reduces phosphorylated PTEN,which can be promoted by overexpressed BMP9,analogously also be attenuated through silencing BMP9.Finally,we introduced a xenograft tumor model to investigate the anti-proliferative effect of Tet,further to explore the effects of BMP9 and PTEN in SW620 cells.Our findings suggested that the anti-cancer activity of Tet in SW620 cells may be mediated partly by up-regulating BMP9,followed by inactivation PI3K/Akt through up-regulating PTEN at least. | Ya Zhou Li Mu Xiao-Lu Liu Qin Li Li-Xuan Ding Hong-Chuan Chen Ying Hu Fu-Shu Li Wen-Juan Sun Bai-Cheng He Ke Wu | 2021 | Genes & Diseases2021，8，3： | 4 |
| 20 | Serum semaphorin 4C as a diagnostic biomarker in breast cancer:A multicenter retrospective study显示文摘Background:To date,there is no approved blood-based biomarker for breast cancer detection.Herein,we aimed to assess semaphorin 4C(SEMA4C),a pivotal protein involved in breast cancer progression,as a serum diagnostic biomarker.Methods:We included 6,213 consecutive inpatients from Tongji Hospital,Qilu Hospital,and Hubei Cancer Hospital.Training cohort and two validation cohorts were introduced for diagnostic exploration and validation.A pan-cancer cohort was used to independently explore the diagnostic potential of SEMA4C among solid tumors.Breast cancer patients who underwent mass excision prior to modified radical mastectomy were also analyzed.We hypothesized that increased pretreatment serum SEMA4C levels,measured using optimized in-house enzymelinked immunosorbent assay kits,could detect breast cancer.The endpoints were diagnostic performance,including area under the receiver operating characteristic curve(AUC),sensitivity,and specificity.Post-surgery pathological diagnosis was the reference standard and breast cancer staging followed the TNM classification.There was no restriction on disease stage for eligibilities.Results:We included 2667 inpatients with breast lesions,2378 patients with other solid tumors,and 1168 healthy participants.Specifically,118 patients with breast cancer were diagnosed with stage 0(5.71%),620 with stage I(30.00%),966 with stage II(46.73%),217 with stage III(10.50%),and 8 with stage IV(0.39%).Patients with breast cancer had significantly higher serum SEMA4C levels than benign breast tumor patients and normal controls(P<0.001).Elevated serum SEMA4C levels had AUC of 0.920(95%confidence interval[CI]:0.900–0.941)and 0.932(95%CI:0.911–0.953)for breast cancer detection in the two validation cohorts.The AUCs for detecting early-stage breast cancer(n=366)and ductal carcinoma in situ(n=85)were 0.931(95%CI:0.916–0.946)and 0.879(95%CI:0.832–0.925),respectively.Serum SEMA4C levels significantly decreased after surgery,and the reduction was more striking after modified radical mastectomy,compared with mass excision(P<0.001).The positive rate of enhanced serum SEMA4C levels was 84.77%for breast cancer and below 20.75%for the other 14 solid tumors.Conclusions:Serum SEMA4C demonstrated promising potential as a candidate biomarker for breast cancer diagnosis.However,validation in prospective settings and by other study groups is warranted. | Ya Wang Long Qiao Jie Yang Xiong Li Yaqi Duan Jiahao Liu Shaoqi Chen Huayi Li Dan Liu Tian Fang Jingjing Ma Xiaoting Li Fei Ye Junxiang Wan Juncheng Wei Qin Xu Ensong Guo Ping Jin Mingfu Wu Lin Zhang Yun Xia Yaqun Wu Jun Shao Yaojun Feng Qing Zhang Zongyuan Yang Gang Chen Qinghua Zhang Xingrui Li Shixuan Wang Junbo Hu Xiaoyun Wang Mona P.Tan Kazuaki Takabe Beihua Kong Qifeng Yang Ding Ma Qinglei Gao | 2021 | Cancer Communications2021，41，12： | 3 |
