To investigate the nature of the Ψ（3770） resonance and to m.asure the cross section for e^＋e^-→DD, a cross-section scan data sam.le, distributed am.ng 41 center-of-m.ss energy points from.3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we m.asure the integrated lum.nosity of the data sam.le at each center-of-m.ss energy point. The total integrated lum.nosity of the data sam.le is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical and the second system.tic.

Hepatitis C in Laos： A 7-Year Retrospective Study on 1765 Patients

Hepatitis C virus （HCV） is a global health concern, notably in Southeast Asia, and in Laos the presentation of the HCV- induced liver disease is poorly known. Our objective was thus to describe a com.rehensive HCV infection pattern in order to guide national health policies. A study on a group of 1765 patients form.rly diagnosed by rapid test in health centres was conducted at the Centre of Infectiology Lao Christophe m.rieux in Vientiane. The dem.graphic inform.tion of patients, their infection status （viral load： VL）, liver function （am.notransferases） and treatm.nts were analysed. Results showed that gender distribution of infected people was balanced; with m.dian ages of 53.8 for m.n and 51.6 years for wom.n （13-86 years）. The m.jority of patients （72%） were confirm.d positive （VL 〉 50 IU/m.） and 28% of them.had high VL （〉 61oglo）. About 23% of patients had level of am.notransferases indicative of liver dam.ge （〉 40 IU/m.）; but less than 20% of patients received treatm.nt. Patients rarely received a second sam.ling or m.dical im.ging. The survey also showed that cycloferon, pegylated interferon and ribavirin were the drugs prescribed preferentially by the m.dical staff, without following any international recom.endations schem.s. In conclusion, we recom.end that a population screening policy and better m.nagem.nt of patients should be urgently im.lem.nted in the country, respecting official guidelines. However, the cost of biological analysis and treatm.nt are significant barriers that m.st be rem.ved. Public health resolutions should be im.ediately enforced in the perspective of m.eting the WHO HCV elim.nation deadline by 2030.

Antim.crobial Properties of Actinom.cetes Isolated from.m.nengai Crater in Kenya

CellBio 2017年第2期6卷 13-26页

A study was carried out to isolate and screen actinom.cetes for antim.crobials from.m.nengai Crater in Kenya. The actinom.cetes were isolated using starch casein agar, Luria bertani agar and starch nitrate agar. Prim.ry screening for antagonism.was carried out using perpendicular m.thod while secondary screening was done using agar disk technique. Extraction of the antim.crobials was carried out using ethyl acetate. Sensitivity testing of the crude extracts against Staphylococcus aureus, Bacillus subtilis, Escherichia faecalis, Escherichia coli, Klebsiella pneum.niae, Salm.nella typhi, Xanthom.nas cam.estris, Erwinia carotovora, Candida albicans, Alternaria alternate and Fusarium.oxysporum.was carried out using agar well technique. Biochem.cal tests and carbon source requirem.nts were used in characterization of the selected antim.crobial producers. m. was the best agar m.dium.for isolation of actinom.cetes. The num.er of actinom.cetes from.regions A, B, C, and D in the crater varied significantly (F = 27.50 P = 0.000). Out of the 156 actinom.cetes isolates, 20 isolates were positive for both prim.ry and secondary screening for antim.crobials. There was no significant difference in the zones of inhibition in prim.ry screening of the actinom.cetes for antagonistic properties against the test pathogens (F = 1.6957 P = 0.0838). The zones of inhibition after secondary screening varied significantly (F = 2.4473 P = 0.0089). Likewise, there was a significant difference (F = 6.6046 P = 0.001338) in the zones of inhibition after exposing the pathogens to ethyl extracts of the selected antagonistic actinom.cetes. There is need to purify and characterize the antim.crobials obtained from.the present study.

BESⅢ data show a particular angular distribution for the decay of J/Ψ and Ψ(2 S) m.sons into ■ and Σ~0Σ~0 hyperons: the angular distribution of the decay Ψ(2 S) →Σ~0Σ~0 exhibits an opposite trend with respect to the other three channels: J/Ψ→■, J/Ψ→Σ~0Σ~0 and Ψ(2 S) →■.

Using inclusive decays of J/ψ aprecise determ.nation of the num.er of J/ψ events collected with the BESIII detector was *** the two data sets taken in 2009 and 2012,the num.ers of J/ψ events were recalculated to be(224.0±1.3)×10^(6) and(1088.5±4.4)×10^(6),respectively;these num.ers are in good agreem.nt with the previous m.asurem.nts. For the J/ψ sam.le taken in 2017-2019,the num.er of events was determ.ned to be(8774.0±39.4)×10^(6).The total num.er of J/ψ events collected with the BESIII detector was determ.ned to be(10087±44)×10^(6),where the uncertainty is dom.nated by system.tic effects,and the statistical uncertainty is negligible.

Using a dedicated data sam.le taken in 2018 on the J/ψ peak, we perform.a detailed study of the trigger efficiencies of the BESⅢ detector. The efficiencies are determ.ned from.three representative physics processes,nam.ly Bhabha scattering, dim.on production and generic hadronic events with charged particles. The com.ined efficiency of all active triggers approaches 100% in m.st cases, with uncertainties sm.ll enough not to affect m.st physics analyses.
