| 2 | Methods for in vitro evaluating antimicrobial activity: A review显示文摘In recent years, there has been a growing interest in researching and developing new antimicrobial agents from various sources to combat microbial resistance. Therefore, a greater attention has been paid to antimicrobial activity screening and evaluating methods. Several bioassays such as disk-diffusion, well diffusion and broth or agar dilution are well known and commonly used, but others such as flow cytofluorometric and bioluminescent methods are not widely used because they require specified equipment and further evaluation for reproducibility and standardization, even if they can provide rapid results of the antimicrobial agent's effects and a better understanding of their impact on the viability and cell damage inflicted to the tested microorganism. In this review article, an exhaustive list of in vitro antimicrobial susceptibility testing methods and detailed information on their advantages and limitations are reported. | mounyr balouiri moulay sadiki saad koraichi ibnsouda | 2016 | Journal of Pharmaceutical Analysis2016，6，2： | 38 |
| 3 | Analysis of pesticide residues in commercially available chenpi using a modified QuEChERS method and GC-MS/MS determination显示文摘To ensure the safety of the commercially available chenpi,a convenient and fast analytical method was developed for the determination of 133 pesticide residues in chenpi using gas chromatography-tandem mass spectrometry(GC-MS/MS).In this study,different extraction solvents,redissolution solvents and adsorbents were tested according to the recovery and purification effect to obtain a modified QuEChERS method.The samples were extracted with acetonitrile.During the clean-up step,octadecyl-modified silica(C18)and graphitized carbon black(GCB)were selected,and aminopropyl(NH2)was used instead of primary secondary amine(PSA)because of its weaker ion exchange capacity which had little effect on the recovery of ditalimfos.Samples were quantified by matrix-matched calibration with internal standards.All pesticides showed good linearity in the respective range,both with values of r2>0.99.The average recoveries of the pesticides spiked samples ranged from 70.0% to 112.2% with the RSDs of 0.2%–14.4%.The modified QuEChERS method was validated and applied to twenty real samples.Five pesticides were found in eight batches,but no pesticide exceeded the maximum residue limits(MRL,MRL reference to European commission). | Shuang Li Peipei Yu Ceng Zhou Ling Tong Dongxiang Li Zhiguo Yu Yunli Zhao | 2020 | Journal of Pharmaceutical Analysis2020，10，1： | 34 |
| 4 | Molecular immune pathogenesis and diagnosis of COVID-19显示文摘Coronavirus disease 2019(COVID-19)is a kind of viral pneumonia which is caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The emergence of SARS-CoV-2 has been marked as the third introduction of a highly pathogenic coronavirus into the human population after the severe acute respiratory syndrome coronavirus(SARS-CoV)and the Middle East respiratory syndrome coro-navirus(MERS-CoV)in the twenty-first century.In this minireview,we provide a brief introduction of the general features of SARS-CoV-2 and discuss current knowledge of molecular immune pathogenesis,diagnosis and treatment of COVID-19 on the base of the present understanding of SARS-CoV and MERS-CoV infections,which may be helpful in offering novel insights and potential therapeutic targets for combating the SARS-CoV-2 infection. | Xiaowei Li Manman Geng Yizhao Peng Liesu Meng Shemin Lu | 2020 | Journal of Pharmaceutical Analysis2020，10，2： | 31 |

| 6 | Structural basis of SARS-CoV-2 3CL^pro and anti-COVID-19 drug discovery from medicinal plants显示文摘The recent pandemic of coronavirus disease 2019(COVID-19)caused by SARS-CoV-2 has raised global health concerns.The viral 3-chymotrypsin-like cysteine protease(3CL^pro)enzyme controls coronavirus replication and is essential for its life cycle.3CL^pro is a proven drug discovery target in the case of severe acute respiratory syndrome coronavirus(SARS-CoV)and Middle East respiratory syndrome coronavirus(MERS-CoV).Recent studies revealed that the genome sequence of SARS-CoV-2 is very similar to that of SARS-CoV.Therefore,herein,we analysed the 3CL^pro sequence,constructed its 3D homology model,and screened it against a medicinal plant library containing 32,297 potential anti-viral phytochemicals/traditional Chinese medicinal compounds.Our analyses revealed that the top nine hits might serve as potential anti-SARS-CoV-2 lead molecules for further optimisation and drug development process to combat COVID-19. | Muhammad Tahir ul Qamar Safar MAlqahtani Mubarak AAlamri Ling-Ling Chen | 2020 | Journal of Pharmaceutical Analysis2020，10，4： | 29 |
| 7 | Recent advances and perspectives of nucleic acid detection for coronavirus显示文摘The recent pneumonia outbreak caused by a novel coronavirus(SARS-CoV-2)is posing a great threat to global public health.Therefore,rapid and accurate identification of pathogenic viruses plays a vital role in selecting appropriate treatments,saving people's lives and preventing epidemics.It is important to establish a quick standard diagnostic test for the detection of the infectious disease(COVID-19)to prevent subsequent secondary spread.Polymerase chain reaction(PCR)is regarded as a gold standard test for the molecular diagnosis of viral and bacterial infections with high sensitivity and specificity.Isothermal nucleic acid amplification is considered to be a highly promising candidate method due to its fundamental advantage in quick procedure time at constant temperature without thermocycler opera-tion.A variety of improved or new approaches also have been developed.This review summarizes the currently available detection methods for coronavirus nucleic acid.It is anticipated that this will assist researchers and clinicians in developing better techniques for timely and effective detection of coro-navirus infection. | Minzhe Shen Ying Zhou Jiawei Ye Abdu Ahmed Abdullah AL-maskri Yu Kang Su Zeng Sheng Cai | 2020 | Journal of Pharmaceutical Analysis2020，10，2： | 27 |
| 8 | Comparative analysis of twenty-five compounds in different parts of Astragalus membranaceus var.mongholicus and Astragalus membranaceus by UPLC-MS/MS显示文摘As a traditional Chinese medicine,the root of Astragalus membranaceus var.mongholicus(AMM)or A.membranaceus(AM)has been widely used in China and other Asian countries for thousands of years.Till now,the flavonoids,phenolic acids and saponins are considered as the main active components contributing to their therapeutic effect in these plants.In order to clarify the distribution and contents of these compounds in different organs of these plants,a rapid and sensitive analytical method for simultaneous determination of 25 active compounds including seven types(i.e.dihydroflavones,isoflavane,isoflavones,flavones,pterocarpans,phenolic acid and saponins)within 10 min was established using ultra-pressure liquid chromatography coupled with tandem mass spectrometry(UPLCeMS/MS).Then,the established method was fully validated and successfully applied to the determination of the contents of these analytes in different parts(root,rhizome,stem,leaf and flower)of AMM and AM.The results indicated that the contents of the same type of compounds in two different species plants were significantly different.Moreover,the obvious differences were also found for the distribution and contents of different type of compounds in five organs of the same species.The present study could provide necessary information for the rational development and utilization of AMM and AM resource. | Yuan Li Sheng Guo Yue Zhu Hui Yan Da-Wei Qian Han-Qing Wang Jian-Qiang Yu Jin-Ao Duan | 2019 | Journal of Pharmaceutical Analysis2019，9，6： | 23 |
| 9 | Anti-diabetic activity of quercetin extracted from Phyllanthus emblica L.fruit: In silico and in vivo approaches显示文摘In this study, molecular interactions of the ligands, quercetin, gallic acid, and metformin with various diabetes mellitus-related protein targets, such as glycogen phosphorylase and peroxisome proliferatoractivated receptor gamma, were assessed. It was revealed that quercetin possesses good binding affinity to both targets. Quercetin is a major constituent of methanolic extracts of Phyllanthus emblica fruit. The antihyperglycemic effect of quercetin in streptozotocin(STZ)-induced diabetic rats was examined. The isolated quercetin administered at a dose of 75 mg/kg body weight produced a maximum decrease of14.78% in blood glucose levels in the diabetic rats after 7 days of treatment. Furthermore, quercetin doses of 50 and 75 mg/kg were shown to significantly improve the profiles of triglycerides, high-density lipoprotein, very-low-density lipoprotein, low-density lipoprotein, and total cholesterol at the end of the study in STZ-induced diabetic rats. The administration of quercetin(25, 50, and 75 mg/kg body weight)daily for 28 days in STZ-induced diabetic rats resulted in a significant decrease in blood glucose and urine sugar levels, with a considerable rise in plasma insulin and hemoglobin levels. Therefore, quercetin is a potential drug with antidiabetic and antihyperglycemic action mediated by changes in the levels of glucose, cholesterol, and triglycerides as indicated by in silico and in vivo studies. | Prabhu Srinivasan S.Vijayakumar Swaminathan Kothandaraman Manogar Palani | 2018 | Journal of Pharmaceutical Analysis2018，8，2： | 18 |

| 11 | Applications of HPLC/MS in the analysis of traditional Chinese medicines显示文摘In China,traditional Chinese medicines(TCMs)have been used in clinical applications for thousands of years.The successful hyphenation of high-performance liquid chromatography(HPLC)and mass spectrometry(MS)has been applied widely in TCMs and biological samples analysis.Undoubtedly,HPLC/MS technique has facilitated the understanding of the treatment mechanism of TCMs.We reviewed more than 350 published papers within the last 5 years on HPLC/MS in the analysis of TCMs.The present review focused on the applications of HPLC/MS in the component analysis,metabolites analysis,and pharmacokinetics of TCMs etc.50% of the literature is related to the component analysis of TCMs,which show that this field is the most popular type of research.In the metabolites analysis,HPLC coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry has been demonstrated to be the powerful tool for the characterization of structural features and fragmentation behavior patterns.This paper presented a brief overview of the applications of HPLC/MS in the analysis of TCMs.HPLC/MS in the fingerprint analysis is reviewed elsewhere. | Miao Li Xiao- Fang Hou Jie Zhang Si-Cen Wang Qiang Fu Lang- Chong He | 2011 | Journal of Pharmaceutical Analysis2011，1，2： | 17 |
| 12 | Quality analysis of commercial samples of Ziziphi spinosae semen(suanzaoren) by means of chromatographic fingerprinting assisted by principal component analysis显示文摘Due to the scarcity of resources of Ziziphi spinosae semen(ZSS), many inferior goods and even adulterants are generally found in medicine markets. To strengthen the quality control, HPLC fingerprint common pattern established in this paper showed three main bioactive compounds in one chromatogram simultaneously. Principal component analysis based on DAD signals could discriminate adulterants and inferiorities. Principal component analysis indicated that all samples could be mainly regrouped into two main clusters according to the first principal component(PC1, redefined as Vicenin II)and the second principal component(PC2, redefined as zizyphusine). PC1 and PC2 could explain 91.42%of the variance. Content of zizyphusine fluctuated more greatly than that of spinosin, and this result was also confirmed by the HPTLC result. Samples with low content of jujubosides and two common adulterants could not be used equivalently with authenticated ones in clinic, while one reference standard extract could substitute the crude drug in pharmaceutical production. Giving special consideration to the well-known bioactive saponins but with low response by end absorption, a fast and cheap HPTLC methodfor quality control of ZSS was developed and the result obtained was commensurate well with that of HPLC analysis. Samples having similar fingerprints to HPTLC common pattern targeting at saponins could be regarded as authenticated ones. This work provided a faster and cheaper way for quality control of ZSS and laid foundation for establishing a more effective quality control method for ZSS. | Shuai Sun Hailing Liu Shunjun Xu Yuzhen Yan Peishan Xie | 2014 | Journal of Pharmaceutical Analysis2014，4，3： | 17 |
| 13 | A holistic strategy for quality and safety control of traditional Chinese medicines by the “iVarious” standard system显示文摘An effective quality control system is the key to ensuring the quality, safety and efficacy of traditional Chinese medicines(TCMs). However, the current quality standard research lacks top-level design and systematic design,mostly based on specific technologies or evaluation methods. To resolve the challenges and questions of quality control of TCMs, a brand-new quality standard system, named 'iVarious', was proposed. The system comprises eight elements in a modular format. Meaning of every element was specifically illustrated via corresponding research instances. Furthermore, frankincense study was taken as an example for demonstrating standards and research process, based on the 'i Various' system. This system highlighted a holistic strategy for effectiveness,security, integrity and systematization of quality and safety control standards of TCMs. The establishment of'i Various' integrates multi-disciplinary technologies and progressive methods, basis elements and key points of standard construction. The system provides a novel idea and technological demonstration for regulation establishment of TCMs quality standards. | Anzhen Chen Lei Sun Hang Yuan Aiying Wu Jingguang Lu Shuangcheng Ma | 2017 | Journal of Pharmaceutical Analysis2017，7，5： | 16 |
| 14 | Determination of fluoroquinolones, sulfonamides, and tetracyclines multiresidues simultaneously in porcine tissue by MSPD and HPLC-DAD显示文摘An efficient method is provided to detect simultaneously some important veterinary drugs from different classes in highly complex animal tissue matrix. This method using matrix solid-phase dispersion (MSPD) and high performance liquid chromatography (HPLC) with diode array detection (DAD) is developed to effectively determine two fiuoroquinolones (enoxacin and lomefioxacin), two sulfonamides (sulfanilamide and sulfamethoxazole) and one tetracycline (tetracycline) simultaneously in porcine tissues. In the process, MSPD methodology was used to treat samples, washed by n-hexane to remove lipid, eluted the analytes with acetonitrile-dichloromethane (1:1, v/v). Solvent acetonitrile and solvent acetic acid (0.1%) were combined in a gradient. HPLC-DAD analysis of the tissue samples was performed within 15 min at a fiow rate of 1.0 mL/min. The results showed that a recovery at 0.1, 0.5 and 1.0 mg/g fortification levels ranged from 80.6% to 99.2% with satisfactory relative standard deviations (RSDs) (below 6.1%, nfi3) and the limits of quantitation (LOQ) ranged from 7 mg/kg to 34 mg/kg in porcine tissues. Utilization of the method in successfully simultaneous analysis of porcine tissue incurred with veterinary drug multiresidues is described. | Hu Yu, Hui Mu, Ying-Mei Hu Chemistry Department of Science School, Xi’an Jiaotong University, Xi’an 710049, China | 2012 | Journal of Pharmaceutical Analysis2012，2，1： | 15 |

| 16 | ON THE DEGREE OF APPROXIMATION BY WAVELET EXPANSIONS显示文摘In this paper we estimate the degree of approximation of wavelet expansions. Our result shows that the degree has the exponential decay for function f(x) ∈ L2 continuous in a finite interval (a,b) which is much superior to those of approximation by polynomial operators and by expansions of classical orthogonal series. | Sun Xiehua (China Institute of Metrology, China) | 1998 | Analysis in Theory and Applications1998，14，1： | 15 |
| 17 | Research advances in the detection of miRNA显示文摘MicroRNAs (miRNAs) are a family of endogenous, small (approximately 22 nucleotides in length), noncoding, functional RNAs. With the development of molecular biology, the research of miRNA biological function has attracted significant interest, as abnormal miRNA expression is identified to contribute to serious human diseases such as cancers. Traditional methods for miRNA detection do not meet current demands. In particular, nanomaterial-based methods, nucleic acid amplification-based methods such as rolling circle amplification (RCA), loop-mediated isothermal amplification (LAMP), strand-displacement amplification (SDA) and some enzyme-free amplifications have been employed widely for the highly sensitive detection of miRNA. MiRNA functional research and clinical diagnostics have been accelerated by these new techniques. Herein, we summarize and discuss the recent progress in the development of miRNA detection methods and new applications. This review will provide guidelines for the development of follow-up miRNA detection methods with high sensitivity and specificity, and applicability to disease diagnosis and therapy. | Jiawei Ye Mingcheng Xu Xueke Tian Sheng Cai Su Zeng | 2019 | Journal of Pharmaceutical Analysis2019，9，4： | 15 |
| 18 | Comparative pharmacokinetics of six major compounds in normal and insomnia rats after oral administration of Ziziphi Spinosae Semen aqueous extract显示文摘Ziziphi Spinosae Semen(ZSS),a traditional Chinese medicine,is used in clinics for the treatment of insomnia in China and other Asian countries.Herein,we described for the first time a comparative pharmacokinetics study of the six major compounds of ZSS in normal control(NC)and para-chlorophenylalanine(PCPA)-induced insomnia model(IM)rats that were orally administered the aqueous extract of ZSS.An ultra-high-performance liquid chromatography coupled with quadrupole orbitrap mass(UHPLC-Q-Orbitrap-MS)method was developed and validated for the simultaneous determination of coclaurine,magnoflorine,spinosin,6000-feruloylspinosin,jujuboside A(JuA),and jujuboside B(JuB)in ZSS in rat plasma.The established approach was successfully applied to a comparative pharmacokinetic study.The systemic exposures of spinosin and 6000-feruloylspinosin were decreased in the IM group compared to the NC group,while plasma clearance(CL)was significantly increased.The Tmax values of JuA and JuB in IM rats were significantly lower than those in NC rats.The T1/2 of JuA in the IM group was significantly accelerated.The pharmacokinetic parameters of coclaurine and magnoflorine were not evidently affected between the two groups.These results indicate that the pathological state of insomnia altered the plasma pharmacokinetics of spinosin,6000-feruloylspinosin,JuA,and JuB in the ZSS aqueous extract,providing an experimental basis for the role of ZSS in insomnia treatment.The comparative pharmacokinetics-based UHPLC-Q-Orbitrap-MS using full-scan mode can therefore provide a reliable and suitable means for the screening of potentially effective substances applied as quality markers of ZSS. | Chenhui Du Yan Yan Chenxi Shen Xiaofang Cui Xiangping Pei Xuemei Qin | 2020 | Journal of Pharmaceutical Analysis2020，10，4： | 14 |
| 19 | Quantitative computed tomography analysis for stratifying the severity of Coronavirus Disease 2019显示文摘To examine the feasibility of using a computer tool for stratifying the severity of Coronavirus Disease 2019(COVID-19)based on computed tomography(CT)images.We retrospectively examined 44 confirmed COVID-19 cases.All cases were evaluated separately by radiologists(visually)and through an in-house computer software.The degree of lesions was visually scored by the radiologist,as follows,for each of the 5 lung lobes:0,no lesion present;1,<1/3 involvement;2,>1/3 and<2/3 involvement;and 3,>2/3 involvement.Lesion density was assessed based on the proportion of ground-glass opacity(GGO),consolidation and fibrosis of the lesions.The parameters obtained using the computer tool included lung volume(mL),lesion volume(mL),lesion percentage(%),and mean lesion density(HU)of the whole lung,right lung,left lung,and each lobe.The scores obtained by the radiologists and quantitative results generated by the computer software were tested for correlation.A Chi-square test was used to test the consistency of radiologist-and computer-derived lesion percentage in the right/left lung,upper/lower lobe,and each of the 5 lobes.The results showed a strong to moderate correlation between lesion percentage scores obtained by radiologists and the computer software(r ranged from 0.7679 to 0.8373,P<0.05),and a moderate correlation between the proportion of GGO and mean lesion density(r=-0.5894,P<0.05),and proportion of consolidation and mean lesion density(r=0.6282,P<0.05).Computer-aided quantification showed a statistical significant higher lesion percentage for lower lobes than that assessed by the radiologists(x^2=8.160,P=0.004).Our experiments demonstrated that the computer tool could reliably and accurately assess the severity and distribution of pneumonia on CT scans. | Cong Shen Nan Yu Shubo Cai Jie Zhou Jiexin Sheng Kang Liu Heping Zhou Youmin Guo Gang Niu | 2020 | Journal of Pharmaceutical Analysis2020，10，2： | 13 |
| 20 | THE CURL IN SEVEN DIMENSIONAL SPACE AND ITS APPLICATIONS显示文摘In higher dimensional spaces Rn(n>3) the usual curl does not have the properties as in R3. In this paper, we established the natural concept of curl in R7 via octonion O. We prove that there exists the curl in Rn if and only if n=3, 7. Some applications are presented, such as the new phenmenon of the differential forms in R7 whcih is different from the ordinary de Rham cohomology and Hodge theory, grad-curl-div type Dirac oper ator in R6, seven dimensional Maxwell equations and Navier-Stokes equations.Supported by the National Natural Science Foundation Of | Lizhong Peng (1) Lei Yang (1) | 1999 | Analysis in Theory and Applications1999，15，3： | 12 |
