1Immunological synergistic mechanisms of trans-/cis-stilbene glycosides in Heshouwu-related idiosyncratic liver injury显示文摘Heshouwu is a traditional non-toxic Chinese medicine commonly used in the clinical setting;however,clinical cases of Heshouwu-induced hepatotoxicity have been frequently reported^([1]).Pharmacoepidemiological studies have found that Heshouwu-induced liver injury occurs only in a small fraction of individuals taking the drug;these patients presented with the typ-Lanzhi He Ping Yin Yakun Meng Jinfa Tang Tingting He Ming Niu Yuming Guo Yun Zhu Jing Jing Chunyu Li Zhijie Ma Jiabo Wang Zhaofang Bai Xiaohe Xiao 2017Science Bulletin2017,62,11:29
2Differential expression of serum miR-126,miR-141 and miR-21 as novel biomarkers for early detection of liver metastasis in colorectal cancer显示文摘Objective:MicroRNAs(miRNAs) have potential as diagnostic biomarkers in cancer.Evaluation of the association between miRNA expression patterns and early detection of liver metastasis in colorectal cancer(CRC) has not been reported.Methods:We investigated the expression of metastasis-associated miRs-31,335,206,141,126,200b,200c,21,Let7a,Let7b and Let7c in localized,liver-metastatic and other organ-metastatic CRC(OM-CRC).Expressions of target miRNAs in serum were evaluated in 116 consecutive localized CRC(L-CRC),72 synchronous liver-metastatic CRC(SLM-CRC) and 36 other OM-CRC by quantitative real-time PCR.Results:Seven of 11 tested miRNAs could be detected from serum.Four miRNAs,miR-126,Let-7a,miR-141 and miR-21 were identified as metastasis-associated miRNAs.Compared with L-CRC,significant upregulated expression was observed for miR-141 and miR-21 in SLM-CRC and OM-CRC,down-regulated expression was observed for miR-126 in SLM-CRC and OM-CRC,and up-regulated expression of Let-7a in OM-CRC.The receiver operating characteristic(ROC) curve showed serum miR-126 had a cut-off [log 10 relative quantity(log 10 RQ)=–0.2005] with 77.78% sensitivity and 68.97% specificity with an area under curve(AUC) of 0.7564,miR-141 had a cut-off(log 10 RQ=–0.2285) with 86.11% sensitivity and 76.11% specificity with an AUC of 0.8279,and miR-21 had a cut-off(log 10 RQ=–0.1310) with 73.61% sensitivity and 66.38% specificity with an AUC of 0.7479.Conclusions:We identified liver metastasis-associated miRNAs,suggesting serum miR-126,miR-141 and miR-21 may be novel biomarkers for clinical diagnosis of early stage liver-metastatic CRC.Jie Yin Zhigang Bai Jianning Song Yun Yang Jin Wang Wei Han Jun Zhang Hua Meng Xuemei Ma Yao Yang Tingting Wang Weirong Li Zhongtao Zhang 2014Chinese Journal of Cancer Research2014,26,1:22
3Guidance for the clinical evaluation of traditional Chinese medicine-induced liver injury Issued by China Food and Drug Administration显示文摘1. Introduction Drug-induced liver injury (DILI), defined as liver injury caused by a drug and/or its metabolites, is a common clinical adverse drug reaction1–4. This type of injury can cause acute liver failure and even death in severe cases5.Xiaohe Xiao Jianyuan Tang Yimin Mao Xiuhui Li Jiabo Wang Chenghai Liu Kewei Sun Yong’an Ye Zhengsheng Zou Cheng Peng Ling Yang Yuming Guo Zhaofang Bai Tingting He Jing Jing Fengyi Li Na An 2019Acta Pharmaceutica Sinica B2019,9,3:22
4GSA:Genome Sequence Archive显示文摘With the rapid development of sequencing technologies towards higher throughput and lower cost, sequence data are generated at an unprecedentedly explosive rate. To provide an efficient and easy-to-use platform for managing huge sequence data, here we present Genome Sequence Archive(GSA; http://gffzzdbc7b6aaae734bddh6fbbvfqbfvqk6xov.ffgz.tsg.suse.edu.cn/gsa or http://gffzz4eaf941a184140e3h6fbbvfqbfvqk6xov.ffgz.tsg.suse.edu.cn), a data repository for archiving raw sequence data. In compliance with data standards and structures of the International Nucleotide Sequence Database Collaboration(INSDC), GSA adopts four data objects(Bio Project, Bio Sample,Experiment, and Run) for data organization, accepts raw sequence reads produced by a variety of sequencing platforms, stores both sequence reads and metadata submitted from all over the world,and makes all these data publicly available to worldwide scientific communities. In the era of big data, GSA is not only an important complement to existing INSDC members by alleviating the increasing burdens of handling sequence data deluge, but also takes the significant responsibility for global big data archive and provides free unrestricted access to all publicly available data in support of research activities throughout the world.Yanqing Wang Fuhai Song Junwei Zhu Sisi Zhang Yadong Yang Tingting Chen Bixia Tang Lili Dong Nan Ding Qian Zhang Zhouxian Bai Xunong Dong Huanxin Chen Mingyuan Sun Shuang Zhai Yubin Sun Lei Yu Li Lan Jingfa Xiao Xiangdong Fang Hongxing Lei Zhang Zhang Wenming Zhao 2017Genomics, Proteomics & Bioinformatics2017,15,1:13
5Antimony oxidation and adsorption by in-situ formed biogenic Mn oxide and Fe–Mn oxides显示文摘Antimony(Sb), which can be toxic at relatively low concentrations, may co-exist with Mn(Ⅱ)and/or Fe(Ⅱ) in some groundwater and surface water bodies. Here we investigated the potential oxidation and adsorption pathways of Sb(Ⅲ and V) species in the presence of Mn(Ⅱ) and Mn-oxidizing bacteria, with or without Fe(Ⅱ). Batch experiments were conducted to determine the oxidation and adsorption characteristics of Sb species in the presence of biogenic Mn oxides(BMOs), which were formed in-situ via the oxidation of Mn(Ⅱ) by a Mn-oxidizing bacterium(Pseudomonas sp. QJX-1). Results indicated that Sb(Ⅲ) ions could be oxidized to Sb(V) ions by BMO, but only Sb(V) originating from Sb(Ⅲ) oxidation was adsorbed effectively by BMO. Introduced Fe(Ⅱ) was chemically oxidized to Fe OOH, the precipitates of which mixed with BMO to form a new compound, biogenic Fe–Mn oxides(BFMO). The BMO part of the BFMO mainly oxidized and the Fe OOH of the BFMO mainly adsorbed the Sb species. In aquatic solutions containing both As(Ⅲ) and Sb(Ⅲ), the BFMO that formed in-situ preferentially oxidized Sb over As but adsorbed As more efficiently. Chemical analysis and reverse transcription real-time polymerase chain reaction revealed that the presence of Fe(Ⅱ), As(Ⅲ) and Sb(Ⅲ) accelerated the oxidation of Mn(Ⅱ) but inhibited the activity of Mn-oxidizing bacteria. These results provide significant insights into the biogeochemical pathways of Sb, Mn(Ⅱ) in aquatic ecosystems, with or without Fe(Ⅱ).Yaohui Bai William A.Jefferson Jinsong Liang Tingting Yang Jiuhui Qu 2017Journal of Environmental Sciences2017,29,4:12
6Landscape of DILI-related adverse drug reaction in China Mainland显示文摘Drug-induced liver injury(DILI)is a type of bizarre adverse drug reaction(ADR)damaging liver(L-ADR)which may lead to substantial hospitalizations and mortality.Due to the general low incidence,detection of L-ADR remains an unsolved public health challenge.Therefore,we used the data of 6.673 million of ADR reports from January 1st,2012 to December 31st,2016 in China National ADR Monitoring System to establish a new database of L-ADR reports for future investigation.Results showed that totally 114,357 ADR reports were retrieved by keywords searching of liver-related injuries from the original heterogeneous system.By cleaning and standardizing the data fields by the dictionary of synonyms and English translation,we resulted 94,593 ADR records reported to liver injury and then created a new database ready for computer mining.The reporting status of L-ADR showed a persistent 1.62-fold change over the past five years.The national population-adjusted reporting numbers of L-ADR manifested an upward trend with age increasing and more evident in men.The annual reporting rate of L-ADR in age group over 80 years old strikingly exceeded the annual DILI incidence rate in general population,despite known underreporting situation in spontaneous ADR reporting system.The percentage of herbal and traditional medicines(H/TM)L-ADR reports in the whole number was 4.5%,while 80.60%of the H/TM reports were new findings.There was great geographical disparity of reported agents,i.e.more cardiovascular and antineoplastic agents were reported in higher socio-demographic index(SDI)regions and more antimicrobials,especially antitubercular agents,were reported in lower SDI regions.In conclusion,this study presented a large-scale,unbiased,unified,and computer-minable L-ADR database for further investigation.Age-,sex-and SDI-related risks of L-ADR incidence warrant to emphasize the precise pharmacovigilance policies within China or other regions in the world.Jiabo Wang Haibo Song Feilin Ge Peng Xiong Jing Jing Tingting He Yuming Guo Zhuo Shi Chao Zhou Zixin Han Yanzhong Han Ming Niu Zhaofang Bai Guangbin Luo Chuanyong Shen Xiaohe Xiao 2022Acta Pharmaceutica Sinica B2022,12,12:12
7Cooperative trajectory optimization for unmanned aerial vehicles in a combat environment显示文摘Dear editor,Unmanned aerial vehicles(UAVs)have been widely used in both civil and military tasks.Owing to the limited payload and economic considerations,however,a single UAV is not capable of carrying out complex tasks,such as large-scale monitoring and surveillance.Therefore,a group of UAVs is usually deployed to perform these tasks.Tingting BAI Daobo WANG 2019Science China(Information Sciences)2019,62,1:7
8Design and Synthesis of Cu@CuS Yolk–Shell Structures with Enhanced Photocatalytic Activity显示文摘Non-spherical Cu@Cu S yolk–shell structures are successfully obtained using Cu_2 O cube templates in a process combining rapid surface sulfidation followed by disproportionation of the Cu_2 O core upon treatment with a hydrochloric acid solution. By employing the above method,Cu@Cu S yolk–shell structures with different morphologies,including octahedral, truncated octahedral, and cuboctahedral shapes, can be synthesized. The void space within the hollow structures provides a unique confined space, where the metallic copper present in the core of a shell can be protected from agglomeration and oxidation. Furthermore,the presence of metal copper in these hollow structurescontributes to improvement in the photocatalytic properties of these materials. The application of these Cu@Cu S structures indeed shows clearly improved photocatalytic performance.Qiuyan Li Fan Wang Linqiang Sun Zhe Jiang Tingting Ye Meng Chen Qiang Bai Chao Wang Xiguang Han 2017Nano-Micro Letters2017,9,3:6
9Helicobacter pylori may participate in the development of inflammatory bowel disease by modulating the intestinal microbiota显示文摘Inflammatory bowel disease(IBD)is a non-specific inflammatory disease of the gastrointestinal(GI)tract that is generally accepted to be closely related to intestinal dysbiosis in the host.GI infections contribute a key role in the pathogenesis of IBD;however,although the results of recent clinical studies have revealed an inverse correlation between Helicobacter pylori(H.pylori)infection and IBD,the exact mechanism underlying the development of IBD remains unclear.H.pylori,as a star microorganism,has been a focus for decades,and recent preclinical and real-world studies have demonstrated that H.pylori not only affects the changes in the gastric microbiota and microenvironment but also influences the intestinal microbiota,indicating a potential correlation with IBD.Detailed analysis revealed that H.pylori infection increased the diversity of the intestinal microbiota,reduced the abundance of Bacteroidetes,augmented the abundance of Firmicutes,and produced short-chain fatty acid-producing bacteria such as Akkermansia.All these factors may decrease vulnerability to IBD.Further studies investigating the H.pylori-intestinal microbiota metabolite axis should be performed to understand the mechanism underlying the development of IBD.Xiaoyin Bai Lingjuan Jiang Gechong Ruan Tingting Liu Hong Yang 2022Chinese Medical Journal2022,,6:5
10Effectiveness and safety of Chinese herbal medicines for hepatitis B virus-related acute-on-chronic liver failure:study protocol for a multicenter randomized controlled trial显示文摘OBJECTIVE:To conduct a multicenter randomized controlled trial of the efficacy of standardized Chinese herbal medicines(CHMs)against acuteon-chronic liver failure(ACLF)and provide reproducible and high-level evidence for clinical practice.METHODS:This is a prospective,multicenter,centrally randomized controlled trial.Patients diagnosed with hepatitis B virus-related ACLF(n=510)will be allocated to the standard medical therapy or CHM group at a 1∶1 ratio.Two CHMs will be used on the basis of the traditional Chinese medicine syndrome:Liangxue Jiedu granules for excess syndromes and Yiqi Jiedu granules for deficiency syndromes.The primary outcome is transplant-free survival at week 12.The secondary outcomes are(a)transplant-free survival at week 24,(b)liver function as assessed using the model for end-stage liver disease score at week 12,(c)liver function as assessed using the Child-Pugh score at week 12,and(d)the incidence of complications at week 12.DISCUSSION:The effectiveness and safety of CHM formulations will be assessed following treatment for ACLF.TRIAL REGISTRATION:The trial was registered at Clinical Trials.gov(NCT03577938)on June 24,2018.Zhang Ning Zhou Chao Wang Lifu He Tingting Wang Yao Wang Yan Bai Yunfeng Li Jun Xiao Xiaohe Gong Man 2020Journal of Traditional Chinese Medicine2020,40,6:5

12Formation control of quad-rotor UAV via PIO显示文摘In this article, the formation control of quad-rotor unmanned aerial vehicle(UAV) via pigeon inspired optimization(PIO) is designed. The nonlinear mathematical model of the quad-rotor UAV is used by applying algebraic graph theory and matrix analysis. A high order consistent formation control algorithm with fixed control topology is designed by using a position deviation matrix to describe its formation. To control the attitude of quad-rotor UAVs, it is difficult to obtain a set of optimal solutions, and hence a PIO based algorithm with variable weight hybridization is proposed. The algorithm is mainly composed of two parts. First, according to the distance between the particles in the iterative process, the inertia weight is dynamically changed,and the coefficient is adjusted to control the degree of influence on its inertia weight. Second, the overall scenario is designed by using MATLAB based simulations which show that the formation control of the quad-rotor UAV is achieved with the help of PIO.BAI TingTing WANG DaoBo MASOOD Rana Javed 2022Science China(Technological Sciences)2022,65,2:4
13TPGS/hyaluronic acid dual-functionalized PLGA nanoparticles delivered through dissolving microneedles for markedly improved chemo-photothermal combined therapy of superficial tumor显示文摘Nanoparticles(NPs)have shown potential in cancer therapy,while a single administration conferring a satisfactory outcome is still unavailable.To address this issue,the dissolving microneedles(DMNs)were developed to locally deliver functionalized NPs with combined chemotherapy and photothermal therapy(PTT).α-Tocopheryl polyethylene glycol succinate(TPGS)/hyaluronic acid(HA)dualfunctionalized PLGA NPs(HD10 NPs)were fabricated to co-load paclitaxel and indocyanine green.HD10 NPs significantly enhanced the cytotoxicity of low-dose paclitaxel because of active and mitochondrial targeting by HA and TPGS,respectively.PTT could further sensitize tumor cells toward chemotherapy by promoting apoptosis into the advanced period,highly activating caspase 3 enzyme,and significantly reducing the expression of survivin and MMP-9 proteins.Further,the anti-tumor effects of HD10 NPs delivered through different administration routes were conducted on the 4 T1 tumorbearing mice.After a single administration,HD10 NPs delivered with DMNs showed the best antitumor effect when giving chemotherapy alone.As expected,the anti-tumor effect was profoundly enhanced after combined therapy,and complete tumor ablation was achieved in the mice treated with DMNs and intra-tumor injection.Moreover,DMNs showed better safety due to moderate hyperthermia.Therefore,the DMNs along with combined chemo-photothermal therapy provide a viable treatment option for superficial tumors.Tingting Peng Yao Huang Xiaoqian Feng Chune Zhu Shi Yin Xinyi Wang Xuequn Bai Xin Pan Chuanbin Wu 2021Acta Pharmaceutica Sinica B2021,11,10:4
14Solvent-and metal-directed lanthanide-organic frameworks based on pamoic acid:observation of slow magnetization relaxation,magnetocaloric effect and luminescent sensing显示文摘Two types of lanthanide coordination polymers, namely, [Ln(PA)(NO_3)(DMA)_3]_n(Ln=Gd(1), Dy(2), Eu(3), Tb(4))(type I), and {[Ln_2(PA)_3(DMF)_4]·2DMF}(Ln=Eu(5), Tb(6))(type II)(PA=Pamoic acid, DMA=dimethylacetamide,DMF=N,N-dimethylformamide), have been synthesized by the reaction of Ln(NO_3)_3·6H_2O with pamoic acid through layer diffusion method. These complexes were characterized by single crystal X-ray diffraction, infrared spectroscopy(IR),thermogravimetric analysis(TGA), fluorescence and magnetic measurements. Solvents and lanthanide atoms in the reaction play an important role in controlling different structures. Type I demonstrated 1-D linear chain structure connected by Ln atoms and PA ligands. Type II exhibited non-interpenetrating 3-D 6-connected 4_36^(12) nets based on binuclear [Ln_2(CO_2)_6(DMF)_4] cores.Magnetic properties of complexes 1–4 were investigated in details. Complex 1 shows significant magnetocaloric effect with–ΔS_m=20.37 J kg^(–1) K^(–1) at 3.0 K and 7 T. Complex 2 exhibits slow relaxation of the magnetization. Complexes 3–6 exhibit both ligand- and metal-centered fluorescent properties. Complex 6 demonstrates fluorescent sensing of DMF and Cu^(2+) ion.Suna Wang Ranran Ma Zhiwei Chen Yunwu Li Tingting Cao Changhui Zhou Junfeng Bai 2016Science China Chemistry2016,59,8:3
15Simulated photo-degradation of dissolved organic matter in lakes revealed by three-dimensional excitation-emission matrix with regional integration and parallel factor analysis显示文摘Simulated photo-degradation of fluorescent dissolved organic matter(FDOM) in Lake Baihua(BH) and Lake Hongfeng(HF) was investigated with three-dimensional excitationemission matrix(3 DEEM) fluorescence combined with the fluorescence regional integration(FRI),parallel factor(PARAFAC) analysis,and multi-order kinetic models.In the FRI analysis,fulvic-like and humic-like materials were the main constituents for both BH-FDOM and HF-FDOM.Four individual components were identified by use of PARAFAC analysis as humic-like components(C1),fulvic-like components(C2),protein-like components(C3) and unidentified components(C4).The maximum 3 DEEM fluorescence intensity of PARAFAC components C1-C3 decreased by about 60%,70% and 90%,respectively after photo-degradation.The multi-order kinetic model was acceptable to represent the photo-degradation of FDOM with correlation coefficient(Radj2)(0.963-0.998).The photo-degradation rate constants(kn) showed differences of three orders of magnitude,from 1.09 × 10-6 to 4.02 × 10-4 min-1,and half-life of multi-order model(T1/2n)ranged from 5.26 to 64.01 min.The decreased values of fluorescence index(FI) and biogenic index(BI),the fact that of percent fluorescence response parameter of Region I(PⅠ,n) showed the greatest change ratio,followed by percent fluorescence response parameter of Region II(PⅡ,n,while the largest decrease ratio was found for C3 components,and the lowest T1/2n was observed for C3,indicated preferential degradation of protein-like materials/components derived from biological sources during photodegradation.This research on the degradation of FDOM by 3 DEEM/FRI-PARAFAC would be beneficial to understanding the photo-degradation of FD OM in natural environments and accurately predicting the environmental behaviors of contaminants in the presence of FDOM.Jin Zhang Fanhao Song Tingting Li Kefu Xie Huiying Yao Baoshan Xing Zhongyu Li Yingchen Bai 2020Journal of Environmental Sciences2020,32,4:3
16Rhubarb-based Chinese herbal formulae for hepatic encephalopa-thy:a systematic review and Meta-analysis显示文摘OBJECTIVE: To evaluate the effectiveness and safety of rhubarb-based Chinese herbal formulae(RCHF), which are widely used to treat hepatic encephalopathy(HE) in China.METHODS: Nine online databases were searched from inception to November 22, 2016. Eligible studies were randomized controlled trials of Traditional Chinese Medicine(TCM) treatment for adult patients(≥ 18 years old) with HE. Outcomes such as mortality rate, clinical response rate, blood ammonia level, and alanine aminotransferase were evaluated between TCM group and control group.RESULTS: Thirty studies involving 2661 HE patients were analyzed. Most studies used RCHF treatment.Compared with conventional treatment as usual,lactulose, and vinegar, RCHF were associated with significant improvement in clinical response rate[risk ratio(RR) = 1.33, 95% confidence interval(CI) =1.25, 1.43, I2= 0%; RR = 1.26, 95% CI = 1.14, 1.38, I2=22%; and RR = 1.19, 95% CI = 1.06, 1.33, I2= 0%, respectively] and significant reductions in levels of blood ammonia and alanine aminotransferase. Only minor RCHF-associated adverse events, such as abdominal pain(0.3%), anal tenesmus(0.3%), and diarrhea(2.3%), were reported, and there were no significant differences in these events between the treatment group and the three types of control group.CONCLUSION: The findings suggest that RCHF may be an alternative treatment option for HE patients. More rigorous multicenter studies with larger samples and longer observational periods are needed to confirm these findings.Zhang Ning Zhou Shuangnan Xiao Xiaohe Wanq Zhen Bai Yunfeng He Tingting Zhou Chao Wang Yao Kun Zhou Wang Zhongxia Liu Bing Larry J.Prokop Matthew C.Hernandez Li Jun Gong Man 2017Journal of Traditional Chinese Medicine2017,37,6:3
17Clinical characteristics of 96 patients with drug-induced acute liver failure:a comparison between Traditional Chinese and Western Medicine显示文摘OBJECTIVE: To compare the causes, clinical symptoms, laboratory test results, and prognosis in patients with acute liver failure(ALF) induced by traditional Chinese medicines(TCM) and by Western Medicines(WM).METHODS: The medical histories of patients who were diagnosed with drug-induced ALF(DALF)(n =96) after hospitalization in the 302 Military Hospital between January 2010 and December 2015 were retrospectively examined.RESULTS: Fifty-eight of the 96 DALF patients(60.4%) had a hepatocellular pattern of DALF, 16 patients(16.7%) had a cholestatic pattern, and 22 patients(22.9%) had a mixed pattern. DALF resolved in 24 patients(25.0%). Twenty-five patients(26.0%)developed chronic liver injury, 43 patients(44.8%)died, and 4 patients(4.2%) underwent liver transplantation. There were 42 ALF patients(43.8%) who received WM, and 32 ALF patients(33.3%) who received TCM. TCM-induced ALF patients had a higher average age [42.4 ± 18.4) vs(33.5 ± 17.9) years,P = 0.04] and higher creatinine and urine nitrogen levels [(155.2 ± 108.8) vs(97.5 ± 130.4) mmol/L, P =0.047;(9.1 ± 7.7) vs(4.3 ± 5.0) mmol/L, P = 0.002, respectively]. Patients with TCM-induced ALF exhibited an increased risk of renal injury [odds ratio(OR),3.75; 95% confidence interval(CI), 1.330-10.577].The 14 patients with TCM-induced ALF who died exhibited higher creatinine levels than the 18 patients with TCM-induced ALF patients who survived[(218.7 ± 111.6) vs(105.8 ± 78.4) mmol/L, P =0.002]. They were also more likely to exhibit ascites(85.7% vs 44.4%, P = 0.017) and hepatorenal syndrome(78.6% vs 22.2%, P = 0.002).CONCLUSION: TCM-induced ALF was more likely to be accompanied by renal injury than was WM-induced ALF, especially in TCM-induced ALF patients who died.He Tingting Zhu Yun Wang Jiabo Gong Man Wang Ruilin Niu Ming Jing Jing Wang Lifu Wang Zhongxia Zhang Ning Bai Zhaofang Bai Yunfeng Li Yonggang Xiao Xiaohe 2017Journal of Traditional Chinese Medicine2017,37,3:3
18A New Ootype of Dinosaur Egg (Faveoloolithidae: Duovallumoolithus shangdanensis oogen, et oosp. nov.) from the Late Cretaceous in the Shangdan Basin, Shaanxi Province, China显示文摘A new ootype collected from the Upper Cretaceous Lijiacun Formation in the Shangdan Basin,Shaanxi Province is described in this paper. Based on general external shape, size, eggshell thickness and honeycomb-like eggshell microstructure, eggs are referable to the oofamily Faveoloolithidae. Compared with other members of Faveoloolithidae, specimens described in this paper show special characteristics:adjacent pores are usually separated by two eggshell units between which often develop interspaces;columnar eggshell units are relatively closely arranged in radial view. According to these characteristics,we erect a new oogenus and a new oospecies: Duovallumoolithus shangdanensis oogen. et oosp. nov. The new discovery expands the diversity of Faveoloolithidae.ZHENG Tingting BAI Yi WANG Qiang ZHU Xufeng FANG Kaiyong YAO Yuan ZHAO Yongqiang WANG Xiaolin 2018Acta Geologica Sinica(English Edition)2018,92,3:2
19Facile fabrication of a biocompatible composite gel with sustained release of aspirin for bone regeneration显示文摘Hydrogels are extracellular-matrix-like biomimetic materials that have wide biomedical applications in tissue engineering and drug delivery.However,most hydrogels cannot simultaneously fulfill the mechanical and cell compatibility requirements.In the present study,we prepared a semi-interpenetrating network composite gel(CG)by incorporating short chain chitosan(CS)into a covalent tetra-armed poly(ethylene glycol)network.In addition to satisfying physicochemical,mechanics,biocompatibility,and cell affinity requirements,this CG easily encapsulated acetylsalicylic acid(ASA)via electrostatic interactions and chain entanglement,achieving sustained release for over 14 days and thus promoting periodontal ligament stem cell(PDLSC)proliferation and osteogenic differentiation.In vivo studies corroborated the capacity of PDLSCs and ASA-laden CG to enhance new bone regeneration in situ using a mouse calvarial bone defect model.This might be attributed to PDLSCs and host mesenchymal stem cells expressing monocyte chemoattractant protein-1,which upregulated M2 macrophage recruitment and polarization in situ,indicating its appealing potential in bone tissue engineering.Yunfan Zhang Xueyu Dou Lingyun Zhang Hufei Wang Ting Zhang Rushui Bai Qiannan Sun Xing Wang Tingting Yu Decheng Wu Bing Han Xuliang Deng 2022Bioactive Materials2022,7,5:2
20Asari Radix et Rhizoma consumption lacks relevance for hepatocellular carcinoma in patients:A retrospective cohort study显示文摘Objective:Although some studies have linked Asari Radix et Rhizoma(Asari Radix)administration to hepatocellular carcinoma(HCC),few studies have examined the association between the development of HCC and use of Asari Radix among patients in China's Mainland.This study aimed to evaluate the realworld association between Asari Radix and HCC in patients to strengthen the understanding of Asari Radix safety.Methods:A retrospective cohort study among hepatitis B virus(HBV)-monoinfected patients and nonHBV-monoinfected patients were performed.Patients over 18 years of age were eligible for inclusion.Prescription records of inpatients and outpatients were inquired to distinguish Asari Radix users and nonusers.The risk of developing HCC among Asari Radix users and nonusers in the HBV cohort and the non-HBV cohort was analyzed.Results:There were 49500 HBV and 133148 non-HBV patients involved in the two cohorts.Among HBV patients(2901 users;46599 nonusers),the prevalence of HCC in Asari Radix users was lower than that in nonusers(145.70 vs.265.43 per 105).Among non-HBV patients(5042 users;128106 nonusers),the prevalence of HCC in Asari Radix users was lower than that in nonusers(81.62 vs.134.11 per 105).None of the hazard ratios(HRs)of Asari Radix exposure ranging from 1 g to 200 g in the two cohorts showed correlation between Asari Radix exposure and hepatocarcinogenesis.Conclusion:An obvious irrelevancy was found between the consumption of Asari Radix and HCC development both in patients with and in those without HBV infection.Use of Asari Radix under 200 g appears safe in terms of HCC risk in the Chinese population;further prospective studies are needed to confirm our results.Zhi-e Fang Yuming Guo Zhilei Wang Tingting He Jiabo Wang Zhaofang Bai Xiaohe Xiao 2022Chinese Herbal Medicines2022,14,3:2
