| 2 | Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control. | Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu | 2021 | Science China(Life Sciences)2021，64，5： | 46 |

| 4 | Effects of large dose of dexamethasone on inflammatory mediators and pancreatic cell apoptosis of rats with severe acute pancreatitis显示文摘AIM: To investigate the influence of high dose of dexamethasone on inflammatory mediators and apoptosis of rats with severe acute pancreatitis (SAP). METHODS: SAP rats were randomly assigned to the model group and treatment group while the normal rats were assigned to the sham operation group. The mortality,ascite volumes,ascites/body weight ratio and pancreas pathological changes of all rats were observed at 3,6 and 12 h after operation. Their contents of amylase and endotoxin in plasma and contents of tumor necrosis factor (TNF-α),phospholipase A2 (PLA2) and IL-6 in serum were also determined. The microarray sections of their pancreatic tissues were prepared,terminal transferase dUTP nick end labeling (TUNEL) staining was performed and apoptotic indexes were calculated. RESULTS: There was no marked difference between treatment group and model group in survival. The contents of amylase and endotoxin in plasma and contents of TNF-α,PLA2 and IL-6 in serum,ascite volumes,ascites/body weight ratio and pancreas pathological scores were all lower in treatment group than in model group to different extents at different time points P < 0.05,58.3 (26.4) ng/L vs 77.535 (42.157) ng/L in TNF-α content,8.00 (2.00) points vs 9.00 (2.00) points in pathological score of pancreas respectively; P < 0.01,0.042 (0.018) EU/mL vs 0.056 (0.0195) EU/mL in endotoxin content,7791 (1863) U/L vs 9195 (1298) U/L in plasma amylase content,1.53 (0.79) vs 2.38 (1.10) in ascites/body weight ratio,8.00 (1.00) points vs 11.00 (1.50) points in pathological score of pancreas; P < 0.001,3.36 (1.56) ng/L vs 5.65 (1.08) ng/L in IL-6 content,4.50 (2.00) vs 7.20 (2.00),4.20 (1.60) vs 6.40 (2.30),3.40 (2.70) vs 7.90 (1.70) in ascite volumes,respectively. The apoptotic indexes of pancreas head and pancreas tail were all higher in treatment group than in model group at 6 h P < 0.01,0.00 (2.00)% vs 0.00 (0.00)%,0.20 (1.80) vs 0.00 (0.00) in apoptosis indexes,respectively. CONCLUSION: The mechanism of dexamethasone treatment in acute pancreatitis is related to its inhibition of inflammatory mediator generation and induction of pancreatic acinar cell apoptosis. | Xi-Ping Zhang Li Chen Qi-Fang Hu Hua Tian Ru-Jun Xu Zhi-Wei Wang Ke-Yi Wang Qi-Hui Cheng Wei Yan Yun Li Qing-Yu Li Qing He Fei Wang | 2007 | World Journal of Gastroenterology2007，13，41： | 29 |
| 5 | Minimal invasive microscopic tooth preparation in esthetic restoration: a specialist consensus显示文摘By removing a part of the structure,the tooth preparation provides restorative space,bonding surface,and finish line for various restorations on abutment.Preparation technique plays critical role in achieving the optimal result of tooth preparation.With successful application of microscope in endodontics for>30 years,there is a full expectation of microscopic dentistry.However,as relatively little progress has been made in the application of microscopic dentistry in prosthodontics,the following assumptions have been proposed:Is it suitable to choose the tooth preparation technique under the naked eye in the microscopic vision?Is there a more accurate preparation technology intended for the microscope?To obtain long-term stable therapeutic effects,is it much easier to achieve maximum tooth preservation and retinal protection and maintain periodontal tissue and oral function health under microscopic vision?Whether the microscopic prosthodontics is a gimmick or a breakthrough in obtaining an ideal tooth preparation should be resolved in microscopic tooth preparation.This article attempts to illustrate the concept,core elements,and indications of microscopic minimally invasive tooth preparation,physiological basis of dental pulp,periodontium and functions involved in tool preparation,position ergonomics and visual basis for dentists,comparison of tooth preparation by naked eyes and a microscope,and comparison of different designs of microscopic minimally invasive tooth preparation techniques.Furthermore,a clinical protocol for microscopic minimally invasive tooth preparation based on target restorative space guide plate has been put forward and new insights on the quantity and shape of microscopic minimally invasive tooth preparation has been provided. | Haiyang Yu Yuwei Zhao Junying Li Tian Luo Jing Gao Hongchen Liu Weicai Liu Feng Liu Ke Zhao Fei Liu Chufan Ma Juergen MSetz Shanshan Liang Lin Fan Shanshan Gao Zhuoli Zhu Jiefei Shen Jian Wang Zhimin Zhu Xuedong Zhou | 2019 | International Journal of Oral Science2019，11，4： | 25 |

| 7 | Casticin-induced apoptosis involves death receptor 5 upregulation in hepatocellular carcinoma cells显示文摘AIM:To investigate the apoptotic activities of casticin in hepatocellular carcinoma(HCC) cells and its molecular mechanisms.METHODS:PLC/PRF/5 and Hep G2 cell lines were cultured in vitro and the inhibitory effect of casticin on the growth of cells was detected by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolim bromide(MTT) assay.The apoptotic cell death was examined using the cell apoptosis enzyme linked immunosorbent assay(ELISA) detection kit,flow cytometry(FCM) after propidium iodide(PI) staining and DNA agarose gel electrophoresis.The caspase activities were measured using ELISA.Reactive oxygen species(ROS) production was evaluated by FCM after dichlorodihydrofluorescein diacetate(DCFH-DA) probe labeling.Intracellular glutathione(GSH) content was measured using a glutathione assay kit.The expression of death receptor(DR)4 and DR5 proteins was analyzed by Western blotting and FCM.RESULTS:Casticin significantly inhibited the growth of human HCC(PLC/PRF/5 and Hep G2) cells in a dosedependent manner(P < 0.05).Casticin increased the percentage of the sub-G1 population in HCC cells in a concentration-dependent manner.The potency of casticin to PLC/PRF/5 cells was higher than that of 5-flurouracil(26.8% ± 4.8% vs 17.4% ± 5.1%) at 10 μmol/L for 24 h.Casticin increased the levels of Histone/DNA fragmentation and the levels of active caspase-3,-8 and-9 in a concentration-dependent manner(P < 0.05).Treatment with 30 μmol/L casticin for 24 h resulted in the formation of a DNA ladder.Casticin reduced the GSH content(P < 0.05),but did not affect the level of intracellular ROS in PLC/PRF/5 and Hep G2 cells.The thiol antioxidants,acetylcysteine(NAC) and GSH restored GSH content and attenuated casticin-induced apoptosis.In contrast,the nonthiol antioxidants,butylated hydroxyanisole and mannitol failed to do so.In the HCC cells treated with casticin for 24 h,DR5 protein level was increased.The expression of DR5 protein induced by casticin was inhibited by NAC.Pretreatment with DR5/Fc chimera protein,a blocking antibody,effectively attenuated the induction of apoptosis by casticin.CONCLUSION:Casticin-induced apoptosis of HCC cells is involved in GSH depletion and DR5 upregulation. | Jun Yang Yun Yang Li Tian Xi-Feng Sheng Fei Liu Jian-Guo Cao | 2011 | World Journal of Gastroenterology2011，17，38： | 21 |
| 8 | Three-dimensional morphometric analysis for hepatectomy of centrally located hepatocellular carcinoma:A pilot study显示文摘AIM: To describe a three-dimensional model(3DM) to accurately reconstruct anatomic relationships of centrally located hepatocellular carcinomas(HCCs).METHODS: From March 2013 to July 2014, reconstructions and visual simulations of centrally located HCCs were performed in 39 patients using a 3D subject-based computed tomography(CT) model with customdeveloped software. CT images were used for the 3D reconstruction of Couinaud's pedicles and hepatic veins, and the calculation of corresponding tumor territories and hepatic segments was performed using Yorktal DMIT software. The respective volume, surgical margin, and simulated virtual resection of tumors were also estimated by this model preoperatively. All patients were treated surgically and the results were retrospectively assessed. Clinical characteristics, imaging data, procedure variables, pathologic features, and postoperative data were recorded and compared to determine the reliability of the model.RESULTS: 3D reconstruction allowed stereoscopic identification of the spatial relationships between physiologic and pathologic structures, and offered quantifiable liver resection proposals based on individualized liver anatomy. The predicted values were consistent with the actual values for tumor mass volume(82.4 ± 109.1 m L vs 84.1 ± 108.9 m L, P = 0.910), surgical margin(10.1 ± 6.2 mm vs 9.1 ± 5.9 mm, P = 0.488), and maximum tumor diameter(4.61 ± 2.16 cm vs 4.53 ± 2.14 cm, P = 0.871). In addition,the number and extent of portal venous ramifications, as well as their relation to hepatic veins, were visualized. Preoperative planning based on simulated resection facilitated complete resection of large tumors located in the confluence of major vessels. And most of the predicted data were correlated with intraoperative findings.CONCLUSION: This 3DM provides quantitative morphometry of tumor masses and a stereo-relationship with adjacent structures, thus providing a promising technique for the management of centrally located HCCs. | Fei Tian Jian-Xiong Wu Wei-Qi Rong Li-Ming Wang Fan Wu Wei-Bo Yu Song-Lin An Fa-Qiang Liu Li Feng Chao Bi Yun-He Liu | 2015 | World Journal of Gastroenterology2015，21，15： | 21 |
| 9 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |

RESULTS: The renal pathological changes were milder in treated group than in model group. The survival at 12 h and renal apoptotic indexes at 6 h were significantly (P < 0.05) higher in treated group than in model group [66.67% vs 100%; 0.00 (0.02)% and 0.00 (0.04)% vs 0.00 (0.00)%, respectively]. The serum CREA content was markedly lower in octreotide-treated group than in model group at 3 h and 6 h (P < 0.01, 29.200 ± 5.710 μmol/L vs 38.400 ± 11.344 μmol/L; P < 0.05, 33.533 ± 10.106 μmol/L vs 45.154 ± 17.435 μmol/L, respectively). The expression level of renal Bax protein was not significantly different between model group and treated groups at all time points. The expression level of renal Bcl-2 protein was lower in Baicalin-treated group than in model group at 6 h [P < 0.001, 0.00 (0.00) grade score vs 3.00 (3.00) grade score]. The Bcl-2 expression level was lower in octreotide-treated group than in model group at 6 h and 12 h [P < 0.05, 0.00 (0.00) grade score vs 3.00 (3.00) grade score; 0.00 (0.00) grade score vs 0.00 (1.25) grade score, respectively]. The serum NO contents were lower in treated groups than in model group at 3 h and 12 h [P < 0.05, 57.50 (22.50) and 52.50 (15.00) μmol/L vs 65.00 (7.50) μmol/L; P < 0.01, 57.50 (27.50) and 45.00 (12.50) μmol/L vs 74.10 (26.15) μmol/L, respectively]. The plasma endotoxin content and serum BUN content (at 6 h and 12 h) were lower in treated groups than in model group. The contents of IL-6, ET-1, TNF-α (at 6 h) and PLA2 (at 6 h and 12 h) were lower in treated groups than in model group [P < 0.001, 3.031 (0.870) and 2.646 (1.373) pg/mL vs 5.437 (1.025) pg/mL; 2.882 (1.392) and 3.076 (1.205) pg/mL vs 6.817 (0.810) pg/mL; 2.832 (0.597) and 2.462 (1.353) pg/mL vs 5.356 (0.747) pg/mL; 16.226 (3.174) and 14.855 (5.747) pg/mL vs 25.625 (7.973) pg/mL; 18.625 (5.780) and 15.185 (1.761) pg/mL vs 24.725 (3.759) pg/mL; 65.10 (27.51) and 47.60 (16.50) pg/mL vs 92.15 (23.12) pg/mL; 67.91 ± 20.61 and 66.86 ± 22.10 U/mL, 63.13 ± 26.31 and 53.63 ± 12.28 U/mL vs 101.46 ± 14.67 and 105.33 ± 18.10 U/mL, respectively]. CONCLUSION: Both Baicalin and octreotide can protect the kidney of rats with severe acute pancreatitis. The therapeutic mechanisms of Baicalin and octreotide might be related to their inhibition of inflammatory mediators and induction of apoptosis. Baicalin might be a promising therapeutic tool for severe acute pancreatitis. | Xi-Ping Zhang Hua Tian Yue-Hong Lai Li Chen Ling Zhang Qi-Hui Cheng Wei Yan Yun Li Qing-Yu Li Qing He Fei Wang | 2007 | World Journal of Gastroenterology2007，13，38： | 17 |

| 13 | Mutational analysis of the SDD sequence motif of a PRRSV RNA-dependent RNA polymerase显示文摘The subgenomic mRNA transcription and genomic replication of the porcine reproductive and respiratory syndrome virus (PRRSV) are directed by the viral replicase. The replicase is expressed in the form of two polyproteins and is subsequently processed into smaller nonstructural proteins (nsps). nsp9, containing the viral replicase, has characteristic sequence motifs conserved among the RNA-dependent RNA polymerases (RdRp) of positive-strand (PS) RNA viruses. To test whether the conserved SDD motif can tolerate other conserved motifs of RNA viruses and the influence of every residue on RdRp catalytic activity, many amino acids substitutions were introduced into it. Only one nsp9 substitution, of serine by glycine (S3050G), could rescue mutant viruses. The rescued virus was genetically stable. Alteration of either aspartate residue was not tolerated, destroyed the polymerase activity, and abolished virus transcription, but did not eliminate virus replication. We also found that the SDD motif was essentially invariant for the signature sequence of PRRSV RdRp. It could not accommodate other conserved motifs found in other RNA viral polymerases, except the GDD motif, which is conserved in all the other PS RNA viruses. These findings indicated that nidoviruses are evolutionarily related to other PS RNA viruses. Our studies support the idea that the two aspartate residues of the SDD motif are critical and essential for PRRSV transcription and represent a sequence variant of the GDD motif in PS RNA viruses. | ZHOU Yan ZHENG HaiHong GAO Fei TIAN DeBin YUAN ShiShan | 2011 | Science China(Life Sciences)2011，54，9： | 15 |
| 14 | Effects of warming and clipping on plant and soil properties of an alpine meadow in the Qinghai-Tibetan Plateau, China显示文摘Climate warming and livestock grazing are known to have great influences on alpine ecosystems like those of the Qinghai-Tibetan Plateau(QTP) in China. However, it is lacking of studies on the effects of warming and grazing on plant and soil properties in these alpine ecosystems. In this study, we reported the related research from manipulative experiment in 2010–2012 in the QTP. The aim of this study was to investigate the individual and combined effects of warming and clipping on plant and soil properties in the alpine meadow ecosystem. Infrared radiators were used to simulate climate warming starting in July 2010, while clipping was performed once in October 2011 to simulate the local livestock grazing. The experiment was designed as a randomized block consisting of five replications and four treatments: control(CK), warming(W), clipping(C) and warming+clipping combination(WC). The plant and soil properties were investigated in the growing season of the alpine meadow in 2012. The results showed that W and WC treatments significantly decreased relative humidity at 20-cm height above ground as well as significantly increases air temperature at the same height, surface temperature, and soil temperature at the depth of 0–30 cm. However, the C treatment did not significantly decrease soil moisture and soil temperature at the depth of 0–60 cm. Relative to CK, vegetation height and species number increased significantly in W and WC treatment, respectively, while vegetation aboveground biomass decreased significantly in C treatment in the early growing season. However, vegetation cover, species diversity, belowground biomass and soil properties at the depth of 0–30 cm did not differ significantly in W, C and WC treatments. Soil moisture increased at the depth of 40–100 cm in W and WC treatments, while belowground biomass, soil activated carbon, organic carbon and total nitrogen increased in the 30–50 cm soil layer in W, C and WC treatments. Although the initial responses of plant and soil properties to experimental warming and clipping were slow and weak, the drought induced by the downward shift of soil moisture in the upper soil layers may induce plant belowground biomass to transfer to the deeper soil layers. This movement would modify the distributions of soil activated carbon, organic carbon and total nitrogen. However, long-term data collection is needed to further explain this interesting phenomenon. | Man Hou XU Fei PENG Quan Gang YOU Jian GUO Xia Fei TIAN Min LIU Xian XUE | 2015 | Journal of Arid Land2015，7，2： | 14 |
| 15 | Celastrol induces ferroptosis in activated HSCs to ameliorate hepatic fibrosis via targeting peroxiredoxins and HO-1显示文摘Ferroptosis is a form of regulated cell death, characterized by excessive membrane lipid peroxidation in an iron-and ROS-dependent manner. Celastrol, a natural bioactive triterpenoid extracted from Tripterygium wilfordii, shows effective anti-fibrotic and anti-inflammatory activities in multiple hepatic diseases. However, the exact molecular mechanisms of action and the direct protein targets of celastrol in the treatment of liver fibrosis remain largely elusive. Here, we discover that celastrol exerts anti-fibrotic effects via promoting the production of reactive oxygen species(ROS) and inducing ferroptosis in activated hepatic stellate cells(HSCs). By using activity-based protein profiling(ABPP) in combination with bio-orthogonal click chemistry reaction and cellular thermal shift assay(CETSA), we show that celastrol directly binds to peroxiredoxins(PRDXs), including PRDX1, PRDX2, PRDX4 and PRDX6,through the active cysteine sites, and inhibits their anti-oxidant activities. Celastrol also targets to heme oxygenase 1(HO-1) and upregulates its expression in activated-HSCs. Knockdown of PRDX1, PRDX2,PRDX4, PRDX6 or HO-1 in HSCs, to varying extent, elevated cellular ROS levels and induced ferroptosis. Taken together, our findings reveal the direct protein targets and molecular mechanisms via which celastrol ameliorates hepatic fibrosis, thus supporting the further development of celastrol as a promising therapeutic agent for liver fibrosis. | Piao Luo Dandan Liu Qian Zhang Fan Yang Yin-Kwan Wong Fei Xia Junzhe Zhang Jiayun Chen Ya Tian Chuanbin Yang Lingyun Dai Han-Ming Shen Jigang Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 14 |
| 16 | Hybrid Model of Molten Steel Temperature Prediction Based on Ladle Heat Status and Artificial Neural Network显示文摘Aiming at the characteristics of the practical steelmaking process,a hybrid model based on ladle heat status and artificial neural network has been proposed to predict molten steel temperature.The hybrid model could overcome the difficulty of accurate prediction using a single mathematical model,and solve the problem of lacking the consideration of the influence of ladle heat status on the steel temperature in an intelligent model.By using the hybrid model method,forward and backward prediction models for molten steel temperature in steelmaking process are established and are used in a steelmaking plant.The forward model,starting from the end-point of BOF,predicts the temperature in argon-blowing station,starting temperature in LF,end temperature in LF and tundish temperature forwards,with the production process evolving.The backward model,starting from the required tundish temperature,calculates target end temperature in LF,target starting temperature in LF,target temperature in argon-blowing station and target BOF end-point temperature backwards.Actual application results show that the models have better prediction accuracy and are satisfying for the process of practical production. | Fei HE Dong-feng HE An-jun XU Hong-bing WANG Nai-yuan TIAN | 2014 | Journal of Iron and Steel Research(International)2014，21，2： | 14 |
| 17 | Sol-gel preparation and characterization of Co_3O_4 nanocrystals显示文摘A new citrate acid-hydrazine sol-gel route for preparation of Co3O4 nanoparticles has been developed. Co3O4 nanoparticles with different particle-sizes and morphology were prepared at different heat-treatment temperatures and the pure cubic nanocrystals of Co3O4 were obtained at 600℃. The synthesis process was monitored by infrared spectroscopy (IR), thermal gravimetric and differential thermal analysis (TG-DTA). The structure and morphology of Co3O4 nanocrystals were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and X-ray-photoelectron spectroscopy (XPS). The infrared absorption bands blueshifted with particle size decreasing, which could be attributed to increasing surface effect. XPS results showed that predominant species at surface layers of Co3O4 nanocrystals are octahedral Co (Ⅲ). | Jinzhang Gao, Yanchun Zhao, Wu Yang, Jianniao Tian, Fei Guan. and Yongjun MaChemistry and Chemical Engineering College, Northwest Normal University, Lanzhou 730070, China | 2003 | Journal of University of Science and Technology Beijing2003，10，1： | 13 |
| 18 | Seroepidemiological Investigation of Lyme Disease and Human Granulocytic Anaplasmosis among People Living in Forest Areas of Eight Provinces in China显示文摘Objective Lyme disease and Human granulocytic anaplasmosis are tick‐borne diseases caused by Borrelia burgdorferi and Anaplasma phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum. Methods Forest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay (IFA). Results Seroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces (the exception being the Miyun area in Beijing). The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks. Conclusion We conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces. | HAO Qin GENG Zhen HOU Xue Xia TIAN Zhen YANG Xiu Jun JIANG Wei Jia SHI Yan ZHAN Zhi Fei LI Guo Hua YU De Shan WANG Hua Yong XU Jian Guo WAN Kang Lin | 2013 | Biomedical and Environmental Sciences2013，26，3： | 13 |

| 20 | Clinical practice guidelines for diagnosis and treatment of patients with non-puerperal mastitis: Chinese Society of Breast Surgery (CSBrS) practice guideline 2021显示文摘The term non-puerperal mastitis(NPM)refers to a group of benign breast diseases of unknown cause that occur in non-puerperal women.The main pathological types are periductal mastitis(PDM)and granulomatous lobular mastitis(GLM).The main clinical manifestations of NPM are breast masses and breast abscesses.Associated fistulas,sinuses,or ulcers can form in the later stages;these tend to be persistent and to fail to heal.The natural course of these conditions is about 9 to 12 months and they frequently recur.There is currently no standard treatment.To help clinicians to make the correct diagnosis and formulate an appropriate treatment plan,the Chinese Society of Breast Surgery has reviewed published reports and conducted discussions between experts to determine the key issues to be included in clinical practice guidelines for NPM.This group has also studied the grading of recommendations assessment,development,and evaluation system,evaluated the relevant evidence,and formulated the following clinical practice guidelines(2021 version)for the diagnosis and treatment of NPM,the aim being to provide a reference standard for breast clinicians. | Fei Zhou Xing-Chen Shang Xing-Song Tian Zhi-Gang Yu | 2021 | Chinese Medical Journal2021，，15： | 12 |
