| 1 | Contemporary crustal movement of continental China obtained by global positioning system(GPS) measurements显示文摘We obtain a unified horizontal velocity field of continental China and vicinity through measurements at 81 GPS stations provided by the National Key Infrastructure Project, Crustal Movement Observation Network of China. The velocity field delineates patterns of movements and deformation of active crustal blocks in continental China under the Eurasia-fixed reference frame. The space-based geodesy also clearly shows for the first time the horizontal movementand deformation of continental China induced by indentation of the Indian plate. The data provide kinematic constraints for simulating dynamic process of continental litho-spheric deformation. | MA Zongjin, CHEN Xinlian, YE Shuhua, LAI Xian, WEI Ziqing, CHEN Junrong, NING Jinsheng, XU Huoze & DING Guoyu1.

| 2 | Progress of Air Pollution Control in China and Its Challenges and Opportunities in the Ecological Civilization Era显示文摘China’s past economic growth has substantially relied on fossil fuels,causing serious air pollution issues.Decoupling economic growth and pollution has become the focus in developing ecological civilization in China.We have analyzed the three-decade progress of air pollution controls in China,highlighting a strategic transformation from emission control toward air quality management.Emission control of sulfur dioxide(SO2)resolved the deteriorating acid rain issue in China in 2007.Since 2013,control actions on multiple precursors and sectors have targeted the reduction of the concentration of fine particulate matter(PM2.5),marking a transition to an air-quality-oriented strategy.Increasing ozone(O3)pollution further requires O3 and PM2.5 integrated control strategies with an emphasis on their complex photochemical interactions.Fundamental improvement of air quality in China,as a key indicator for the success of ecological civilization construction,demands the deep de-carbonization of China’s energy system as well as more synergistic pathways to address air pollution and global climate change simultaneously. | Xi Lu Shaojun Zhang Jia Xing Yunjie Wang Wenhui Chen Dian Ding Ye Wu Shuxiao Wang Lei Duan Jiming Hao | 2020 | Engineering2020，6，12： | 24 |

| 4 | Effect of L-NAME on nitric oxide and gastrointestinal motility alterations in cirrhotic rats显示文摘AIM: To invsstigare the effect of L-NAME on nitric oxide andgastriubtestubal motility alterations in cirrhotic ratsMETHODS: Rats with cirrhosis induced by carbontetrachloride were randomly divided into two groups, one( n= 13) receiving 0. 5 mg@ kg-1 per clay of NG-nitro-L-argininemethyl ester (L-NAME), a nitric oxide synthase inhibitor,for 10 days, whereas the other group ( n = 13) and control( n = 10) rats were administrated the same volume of 9 g@ L-1saline.Half gastric emptying time and 2 h residual rate weremeasured by SPECT, using 99m Tc-DTPA-labeled bariumsuifate as test meal. Gastrointestinal transition time wasrecorded simultaneously. Serum concentration of nitrcoxide (NO) was determined by the kinetic cadmiunreduction and colorimetric methods. ImmunohistochemicalSABC method was used to observe the expression anddistribution of three types of nitric oxide synthase (NOS)isoforms in the mt gastrointestinal tract. Western blot wasused to detect expression of gastrointestinal NOS isoforms.RESULTS: Half gastric emptying time and trans-gastrointestinal time were significantly prolonged( 124.0 ± 26.4min; 33.7± 8.9min;72.1 ± 15.3 min; P<0.01), (12.4±0.5h; 9.5±0.3 h; 8.2±0.8 h; P<0.01), 2h residual rate wasraised in cirrhotic rots than in controls and cirrhotic ratstreated with L-NAME(54.9± 7.6 % ,13.7 ± 3.2 %, 34.9± 10.3%, P< 0.01). Serum concentration of NO was significantlyincreased in cirrhotic rots than in the other groups (8.20 ± 2.48)μmol@L-1, (5.94± 1.07) μmol@L-1 ,and control (5.66± 1.60) tμmol@L-1, P< 0.01. NOS staining intensities which weremainly located in the gastrointestinal tissues were markedlylower in cirrhotic rats than in the controls and cirrhotic ratsafter treated with L- NAME.CONCLUSION: Gastrointestinal motility was remarkablyinhibited in cirrhotic rats, which could he alleviated by L-NAME. Nitric oxide may play an important role in theinhibition of gastrointestinal motility in cirrhotic rats. | Xin Wang Zong-You Zhang Mei Lan Ji-Yan Miao Xue-Gang Guo Yong-Quan Shi Yan-Qiu Zhao Jie Ding Kai-Cun Wu Dai-Ming Fan,Institute of Digestive disease,Xijing Hospital,Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China Yue-Xia Zhong,Emergency Department,Tangdu Hospital,Fourth Military Medical University,Xi’an 710038,Shaanxi Province,China Ju Lu,Class EE 87,Department of Electronic Engineering,Tsinghua University,Beijing 100084,China Bo-Rong Pan,Oncology Center,Xijing Hospital,Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China | 2002 | World Journal of Gastroenterology2002，8，2： | 19 |

| 6 | Effect of Qingfei Mixture (清肺合剂) on Pediatric Mycoplasma Pneumoniae Pneumonia with Phlegm Heat Obstructing Fei (Lung) Syndrome显示文摘Objective: To explore the effect and mechanism of Qingfei Mixture(清肺合剂), a Chinese medicine, in treating mycoplasma pneumonia(MP) in MP patients and rat model. Methods: A total of 46 MP children with phlegm heat obstructing Fei(Lung) syndrome were randomly assigned to two groups by the method of random number table, with 23 children in each group. The control group was treated with intravenous infusion of azithromycin; the treatment group received intravenous infusion of azithromycin and oral administration of Qingfei Mixture. The treatment course was 7 days. Major symptoms and minor symptoms were observed and scored before and after treatments. A rat model of MP was also established. A total of 120 wistar rats were randomly divided into 5 groups: a normal group, infection group, Qingfei Mixture treatment group, azithromycin treatment group, and Qingfei Mixture + azithromycin treatment group. Each group contained 24 rats, from which every 6 were euthanatized 1, 3, 7 and 14 days after infection. MP DNA in pulmonary tissue homogenates was detected using real-time fluorescence quantitative polymerase chain reaction. Pathology was assessed after hematoxylin(HE) staining and lung tissue pathology scores were determined in pulmonary tissue. Transmission electron microscopic detection and electronic image analysis were performed on lung tissue 3 days after infection. Interleukin(IL)-17 was detected in serum using enzymelinked immunosorbent assay(ELISA) 7 days after infection. Results: In the clinical study, both control and the treatment group showed improved results on removing symptoms of phlegm heat syndrome compared to the control group(P<0.05). In animal experiments, On the 7th day after MP infection, as detected by electron microscopy, the pulmonary capillary basement membranes of the azithromycin + Qingfei Mixture treatment group were much thinner than those of the azithromycin or Qingfei mixture treatment groups(P<0.05). The level of serum IL-17 in the azithromycin + Qingfei Mixture treatment group was lower than that in the azithromycin or Qingfei Mixture groups(P<0.01). Conclusion: Both Qingfei Mixture and azithromycin have therapeutic effects on mycoplasma pneumoniae pneumonia, but the combination of both agents had the greatest effect. | YANG Ai-jun XI Kun YAO Yan-qing DING Ying-xue YANG Li-jun CUI Hong | 2017 | Chinese Journal of Integrative Medicine2017，23，9： | 15 |
| 7 | Detecting soil salinity with arid fraction integrated index and salinity index in feature space using Landsat TM imagery显示文摘Modeling soil salinity in an arid salt-affected ecosystem is a difficult task when using remote sensing data because of the complicated soil context(vegetation cover,moisture,surface roughness,and organic matter)and the weak spectral features of salinized soil.Therefore,an index such as the salinity index(SI)that only uses soil spectra may not detect soil salinity effectively and quantitatively.The use of vegetation reflectance as an indirect indicator can avoid limitations associated with the direct use of soil reflectance.The normalized difference vegetation index(NDVI),as the most common vegetation index,was found to be responsive to salinity but may not be available for retrieving sparse vegetation due to its sensitivity to background soil in arid areas.Therefore,the arid fraction integrated index(AFII)was created as supported by the spectral mixture analysis(SMA),which is more appropriate for analyzing variations in vegetation cover(particularly halophytes)than NDVI in the study area.Using soil and vegetation separately for detecting salinity perhaps is not feasible.Then,we developed a new and operational model,the soil salinity detecting model(SDM)that combines AFII and SI to quantitatively estimate the salt content in the surface soil.SDMs,including SDM1 and SDM2,were constructed through analyzing the spatial characteristics of soils with different salinization degree by integrating AFII and SI using a scatterplot.The SDMs were then compared to the combined spectral response index(COSRI)from field measurements with respect to the soil salt content.The results indicate that the SDM values are highly correlated with soil salinity,in contrast to the performance of COSRI.Strong exponential relationships were observed between soil salinity and SDMs(R2>0.86,RMSE<6.86)compared to COSRI(R2=0.71,RMSE=16.21).These results suggest that the feature space related to biophysical properties combined with AFII and SI can effectively provide information on soil salinity. | Fei WANG Xi CHEN GePing LUO JianLi DING XianFeng CHEN | 2013 | Journal of Arid Land2013，5，3： | 14 |
| 8 | 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 |

| 10 | Comparative investigation on high-speed grinding of TiCp/Ti–6Al–4V particulate reinforced titanium matrix composites with single-layer electroplated and brazed CBN wheels显示文摘In order to develop the high-efficiency and precision machining technique of Ti Cp/Ti–6Al–4V particulate reinforced titanium matrix composites(PTMCs), high-speed grinding experiments were conducted using the single-layer electroplated cubic boron nitride(CBN) wheel and brazed CBN wheel, respectively. The comparative grinding performance was studied in terms of grinding force, grinding temperature, grinding-induced surface features and defects. The results display that the grinding forces and grinding temperature obtained with the brazed CBN wheel are always lower than those with the electroplated CBN wheel. Though the voids and microcracks are the dominant grinding-induced surface defects, the brazed CBN wheel produces less surface defects compared to the electroplated wheel according to the statistical analysis results. The maximum materials removal rate with the brazed CBN wheel is much higher than that with the electroplated one. All above indicate that the single-layer brazed CBN super-abrasive wheel is more suitable for high-speed grinding of PTMCs than the electroplated counterpart. | Li Zheng Ding Wenfeng Shen Long Xi Xinxin Fu Yucan | 2016 | Chinese Journal of Aeronautics2016，29，5： | 11 |
| 11 | Effect of Integrated Chinese and Western Medicine Therapy on Severe Hand, Foot and Mouth Disease: A Prospective, Randomized, Controlled Trial显示文摘Objective: To evaluate the efficacy and safety of Chinese medicine(CM) plus Western medicine(WM) in the treatment of pediatric patients with severe hand, foot and mouth disease(HFMD) by conducting a prospective, controlled, and randomized trial. Methods: A total of 451 pediatric patients with severe HFMD were randomly assigned to receive WM therapy alone(224 cases, WM therapy group) or CM [Reduning Injection(热毒宁注射液) or Xiyanping Injection(喜炎平注射液)] plus WM therapy(227 cases, CM plus WM therapy group) for 7–10 days, according to a web-based randomization system. The primary outcome was fever clearance time, which was presented as temperature decreased half-life time. The secondary outcomes included the rate of rash/herpes disappearance within 120 h, as well as the rate for cough, runny nose, lethargy and weakness, agitation or irritability, and vomiting clearance within 120 h. The drug-related adverse events were also recorded. Results: The temperature decreased half-life time was 40.4 h in the WM therapy group, significantly longer than 27.2 h in the CM plus WM therapy group(P<0.01). Moreover, the rate for rash/herpes disappearance within 120 h was 43.6%(99/227) in the CM plus WM therapy group, significantly higher than 29.5%(66/224) in the WM therapy group(P<0.01). In addition, the rate for cough, lethargy and weakness, agitation or irritability disappearance within 120 h was 32.6%(74/227) in the CM plus WM therapy group, significantly higher than 19.2%(43/224) in the WM therapy group(P<0.01). No drug-related adverse events were observed during the course of the study. Conclusions: The combined CM and WM therapy achieved a better therapeutic efficacy in treating severe HFMD than the WM therapy alone. Reduning or Xiyanping Injections may become an important complementary therapy to WM for relieving the symptoms of severe HFMD. | LI Xiu-hui LI Shuang-jie XU Yi WEI Dan SHI Qing-sheng ZHU Qing-xiong YANG Tong DING Jian-bo TIAN Yi-mei HUANG Ji-han WANG Kun WEN Tao ZHANG Xi | 2017 | Chinese Journal of Integrative Medicine2017，23，12： | 10 |

| 14 | Epidemiology,clinical and laboratory characteristics of currently alive HIV-1 infected former blood donors naive to antiretroviral therapy in Anhui Province,China显示文摘Background Unregulated commercial blood/plasma collection among farmers occurred between 1992 and 1995 in central China and caused the second major epidemic of human immunodeficiency virus type 1 (HIV-1) infection in China. It is important to characterize HIV-1-infected former blood donors and to study characteristics associated with disease progression for future clinical intervention and vaccine development. Methods A cross-sectional study was performed on HIV-1-infected former blood donors (FBDs) and age-matched HIV-seronegative local residents. Demographic, epidemiologic, clinical and key laboratory data were collected from all study participants. Both unadjusted and adjusted multivariate linear regressions were employed to analyze the association of the decrease of CD4+ T-cell counts with other characteristics. Results Two hundred and ninety-four HIV-1-infected FBDs and 59 age-matched HIV-seronegative local residents were enrolled in this study. The unregulated blood/plasma collection occurred more than a decade (10.8 -12.8 years) ago, which caused the rapid spread of HIV-1 infection and the high prevalence of co-infection with hepatitis C virus (HCV, 89.5%); hepatitis B virus (HBV) co-infection was observed in only 11 HIV+participants (3.7%). Deterioration in both clinical manifestation and laboratory parameters and increase of viral loads were observed in parallel with the decrease of CD4+ T-cell counts. The decrease of total lymphocyte counts (P<0.001) and hemoglobin levels (P<0.001) and the appearance of dermatosis (P=0.03) were observed in parallel with the decrease of CD4+ T-cell counts whereas viral loads (P<0.001) and CD8+ T-cell counts (P=0.01) were inverselyassociated with CD4+ T-cell counts. Conclusions Co-infection with HCV but not HBV is highly prevalent among HIV-1-infected FBDs. CD4+ T-cell counts is a reliable indicator for disease progression among FBDs. Total lymphocyte counts, hemoglobin level and appearance of dermatosis were positively associated with CD8+ T-cell counts and viral loads were inversely associated with the decreased CD4+ T-cell counts. | XU Jian-qing WANG Jian-jun HAN Li-feng XU Chen RUAN Yu-hua XU Zhen-hou CHEN Xi LIU Zhen-dong WANG Jun SU Bing DING Xin-ping GAO Bing GU Yong-bin CAO Xiao-yun XING Hui HONG Kun-xue PENG Hong ZHAO Quan-bi YUAN Lin FENG Yi ZHANG Gui-yun MA Li-ying WU Lan SHAO Yi-ming | 2006 | Chinese Medical Journal2006，，23： | 9 |
| 15 | Highly expressed BMP9/GDF2 in postnatal mouse liver and lungs may account for its pleiotropic effects on stem cell differentiation,angiogenesis,tumor growth and metabolism显示文摘Bone morphogenetic protein 9(BMP9)(or GDF2)was originally identified from fetal mouse liver cDNA libraries.Emerging evidence indicates BMP9 exerts diverse and pleiotropic functions during postnatal development and in maintaining tissue homeostasis.However,the expression landscape of BMP9 signaling during development and/or in adult tissues remains to be analyzed.Here,we conducted a comprehensive analysis of the expression landscape of BMP9 and its signaling mediators in postnatal mice.By analyzing mouse ENCODE transcriptome datasets we found Bmp9 was highly expressed in the liver and detectable in embryonic brain,adult lungs and adult placenta.We next conducted a comprehensive qPCR analysis of RNAs isolated from major mouse tissues/organs at various ages.We found that Bmp9 was highly expressed in the liver and lung tissues of young adult mice,but decreased in older mice.Interestingly,Bmp9 was only expressed at low to modest levels in developing bones.BMP9-associated TGFβ/BMPR type I receptor Alk1 was highly expressed in the adult lungs.Furthermore,the feedback inhibitor Smads Smad6 and Smad7 were widely expressed in mouse postnatal tissues.However,the BMP signaling antagonist noggin was highly expressed in fat and heart in the older age groups,as well as in kidney,liver and lungs in a biphasic fashion.Thus,our findings indicate that the circulating BMP9 produced in liver and lungs may account for its pleiotropic effects on postnatal tissues/organs although possible roles of BMP9 signaling in liver and lungs remain to be fully understood. | Wei Liu Zhongliang Deng Zongyue Zeng Jiaming Fan Yixiao Feng Xi Wang Daigui Cao Bo Zhang Lijuan Yang Bin Liu Mikhail Pakvasa William Wagstaff Xiaoxing Wu Huaxiu Luo Jing Zhang Meng Zhang Fang He Yukun Mao Huiming Ding Yongtao Zhang Changchun Niu Rex C.Haydon Hue H.Luu Jennifer Moriatis Wolf Michael J.Lee Wei Huang Tong-Chuan He Yulong Zou | 2020 | Genes & Diseases2020，7，2： | 9 |
| 16 | Assessment of the sources and transformations of nitrogen in a plain river network region using a stable isotope approach显示文摘The great spatial and temporal variability in hydrological conditions and nitrogen(N)processing introduces large uncertainties to the identification of N sources and quantifying N cycles in plain river network regions. By combining isotopic data with chemical and hydrologic measurements, we determined the relative importance of N sources and biogeochemical N processes in the Taige River in the East Plain Region of China. The river was polluted more seriously by anthropogenic inputs in winter than in summer. Manure and urban sewage effluent were the main nitrate(NO-3) sources, with the nitrification of N-containing organic materials serving as another important source of NO-3. In the downstream, with minor variations in hydrological conditions, nitrification played a more important role than assimilation for the decreasing ammonium(NH+4-N) concentrations.The N isotopic enrichment factors(ε) during NH+4utilization ranged from- 13.88‰ in March to- 29.00‰ in July. The ratio of the increase in δ18O and δ15N of river NO-3in the downstream was 1.04 in January and 0.92 in March. This ratio indicated that NO-3assimilation by phytoplankton was responsible for the increasing δ15N and δ18O values of NO-3in winter. The relationships between δ15N of particulate organic nitrogen and isotopic compositions of dissolved inorganic nitrogen indicated that the phytoplankton in the Taige River probably utilized NH+4preferentially and mainly in summer, while in winter, NO-3assimilation by phytoplankton was dominant. | Jingtao Ding Beidou Xi Qigong Xu Jing Su Shouliang Huo Hongliang Liu Yijun Yu Yanbo Zhang | 2015 | Journal of Environmental Sciences2015，27，4： | 9 |
| 17 | Thyroid function reference ranges during pregnancy in a large Chinese population and comparison with current guidelines显示文摘Background: A correct thyroid function reference range is important for the accurate diagnosis of thyroid disease during pregnancy. However, there is no consensus on whether thyroid function reference ranges in Chinese population should follow the America Thyroid Association (ATA) guidelines. This study aimed to establish a thyroid function reference range more suited to the Chinese population by evaluating the current thyroid function reference range in pregnant Chinese women and comparing it to the ATA guidelines. Methods: A total of 52,027 pregnant women were enrolled from January 2013 to December 2016. Thyroid stimulating hormone (TSH), free thyroxine (FT4), and thyroid peroxidase antibody (TPOAb) levels were tested during the first and third trimesters of pregnancy. Reference ranges of TSH and FT4 were established from the 2.5th and 97.5th percentiles of the TPOAb-negative population of women. The Mann-Whitney U test was used to compare thyroid hormones between the TPOAb-positive and TPOAbnegative groups. Results: We obtained that the TSH reference ranges were 0.03 to 3.52 mU/L and 0.39 to 3.67 mU/L, and the FT4 reference ranges were 11.7 to 19.7 pmol/L and 9.1 to 14.4pmol/L, in the firstand third trimester, respectively. If we used the 2011 ATA criteria about 7.0% and 4.0% pregnant women would be over diagnosed in first and third trimester, respectively, compared with local population thyroid hormone reference. When we compared our local criteria with the new 2017 ATA criteria, about 1.2% and 0.8% pregnant women would have a missed diagnosis in first and third trimester, respectively. Conclusions: Based on our data, which is in line with the current ATA guidelines, a population-based thyroid function reference range would be the first choice for diagnosis of thyroid disease during pregnancy in China. In case such population-based thyroid function reference ranges are unavailable in the east of China, our reference ranges can be adopted, if the same assay is used. | Xi Yang Yu Meng Yong Zhang Chen Zhang Fei Guo Shuai Yang Rong Ding Jian-Xia Fan | 2019 | Chinese Medical Journal2019，，5： | 9 |

The ScFvs DNA was ligated into the phagmid vector pCANTAB5E and the ligated sample was transformed into competent E. Coli TG1. The transformed cells were infected with M13K07 helper phage to form MG7 recombinant phage antibody library. The volume and recombinant rate of the library were evaluated by means of bacterial colony count and restriction analysis. After two rounds of panning with gastric cancer cell line KATOⅢ of highly expressing MG7binding antigen, the phage clones displaying ScFv of the antibody were selected by ELISA from the enriched phage clones. The antigen-binding affinity of the positive clone was detected by competition ELISA. HB2151 E. Coli was transfected with the positive phage clone demonstrated by competition ELISA for production of a soluble form of the MG7 ScFv. ELISA assay was used to detect the antigenbinding affinity of the soluble MG7 ScFv. Finally, the relative molecular mass of soluble MG7 ScFv was measured by SDS-PAGE.RESULTS The VH, VL and ScFv DNAs were about 340bp,320bp and 750bp, respectively. The volume of the library was up to 2 × 106 and 8 of 11 random clones were recombinants. Two phage clones could strongly compete with the original MG7 antibody for binding to the antigen expressed on KATO Ⅲ cells. Within 2 strong positive phage clones, the soluble MG7 ScFv from one clone was found to have the binding activity with KATO Ⅲ cells.SDS-PAGE showed that the relative molecular weight of soluble MG7 ScFv was 32.CONCLUSION The MG7 ScFv was successfully produced by phage antibody technology, which may be useful for broadening the scope of application of the antibody. | Zhao-Cai Yu Jie Ding Yong-Zhan Nie Dai-Ming Fan Xue-Yong Zhang Department of Gastroenterology,Xijing Hospital,Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China | 2001 | World Journal of Gastroenterology2001，7，4： | 9 |
| 19 | Prevention and control of HIV/AIDS in China:lessons from the past three decades显示文摘In the past 37 years,human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS)has undergone various major transmission routes in China,with the world most complex co-circulating HIV-1 subtypes,even the prevalence is still low.In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection,China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing,which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection.China has been providing free antiretroviral therapy(ART)since 2003,which covered>80%of the identified patients and achieved a viral suppression rate of 91%.To bend the curve of increasing the disease burden of HIV and finally end the epidemic,China should consider constraining HIV spread through sexual transmission,narrowing the gaps in identifying HIV cases,and the long-term effectiveness and safety of ART in the future. | Jun-Jie Xu Meng-Jie Han Yong-Jun Jiang Hai-Bo Ding Xi Li Xiao-Xu Han Fan Lv Qing-Feng Chen Zi-Ning Zhang Hua-Lu Cui Wen-Qing Geng Jing Zhang Qi Wang Jing Kang Xiao-Lin Li Hong Sun Ya-Jing Fu Ming-Hui An Qing-Hai Hu Zhen-Xing Chu Ying-Jie Liu Hong Shang | 2021 | Chinese Medical Journal2021，，23： | 9 |
