This article is aimed to provide a method for the simultaneous analysis of five heavy metals, including Cu, As, Pb, Cd, and Hg, in Chuanxiong Rhizoma and Gastrodiae Rhizoma through ICP-MS. Five heavy metals were determined by an inductively coupled plasma-mass spectrometry method after microwave-assisted digestion. The linear correlation coefficients were all better than 0.999. The lowest limits of quantification for all target elements were 0.003 0.134 ug·L-1, while the recovery values ranged from 80.04% 118.34%. This method was accurate, convenient, rapid, and highly sensitive, and can be applied to determine five heavy metals, including Cu, As, Pb, Cd, and Hg in Chuanxiong Rhizoma and Gastrodiae Rhizoma.

ABSTRACT:The virulence genes ,hemolytic and antibiotic resistance characteristics from 19 isolated Streptococcus suis se‐rotype 2 in Anhui Province were investigated in this study .The PCR method was developed for detecting cps2J ,mrp ,ep f and sly gene;the plate method and micro‐ELISA were developed for detecting the hemolytic type and hemolytic titer ;the K‐B method was developed for detecting antibiotic resistance of 25 kinds of antibiotics .Results showed that there were 11 strains with the dominant virulence genotype of cps2J+ /mrp+ /ep f+ /sly+ accounting for 57 .9% .All strains were α‐hemolysis orβ‐hemolysis ,with hemolytic titer of 1∶4 to 1∶128 .Strains sensitive to rifapentine ,ceftazidime ,florfenicol and cefazolin was existed in high frequency with the sensitive rates for 84 .2% ,and the resistance to doxycycline ,tetracycline ,bacitracin and sul‐famethoxazole was existed in high frequency with the resistance rates for 82 .9% .The multi‐antibiogram typing was doxycyc‐line ,tetracycline ,bacitracin and sulfamethoxazole account for 63 .2% .In conclusion ,the distribution of virulence genes of S .suis 2 Anhui isolates was similar with that of domestic reported strains ,and there was some differences with that of over‐seas reported strains .CPS ,MRP ,EPF and SLY are important virulence factors and the incompleteness of sly gene had no effect to its haemolyticus .The multi‐antibiotic resistance of S .suis 2 Anhui isolates was serious .There is difference for anti‐biogram typing between S .suis 2 Anhui isolates and those in other areas .

Objective To investigate the antimicrobial resistance profile of the clinical isolates collected from selected hospitals across China. Methods Twenty-nine general hospitals and five children's hospitals were involved in this program. Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems. Results were interpreted according to CLSI 2017 breakpoints. Results A total of 190 610 clinical isolates were collected from January to December 2017, of which gram negative organisms accounted for 70.8％ (134 951/190 610) and gram positive cocci 29.2％ (55 649/190 610). The prevalence of methicillin-resistant strains was 35.3％ in S. aureus (MRSA) and 80.3％ in coagulase negative Staphylococcus (MRCNS) on average. MR strains showed much higher resistance rates to most of the other antimicrobial agents than MS strains. However, 91.6％ of MRSA strains were still susceptible to trimethoprim-sulfamethoxazole, while 86.2％ of MRCNS strains were susceptible to rifampin. No staphylococcal strains were found resistant to vancomycin. E. faecalis strains showed much lower resistance rates to most of the drugs tested (except chloramphenicol) than E. faecium. Vancomycin-resistant Enterococcus (VRE) was identified in both E. faecalis and E. faecium. The identified VRE strains were mainly vanA, vanB or vanM type based on phenotype or genotype. The proportion of PSSP or PRSP strains in the non-meningitis S.pneumoniae strains isolated from children decreased but the proportion of PISP strains increased when compared to the data of 2016. Enterobacteriaceae strains were still highly susceptible to carbapenems. Overall, less than 10％ of these strains (excluding Klebsiella spp.) were resistant to carbapenems. The prevalence of imipenem-resistant K. pneumoniae increased from 3.0％ in 2005 to 20.9％ in 2017, and meropenem-resistant K. pneumoniae increased from 2.9％ in 2005 to 24.0％ in 2017, more than 8-fold increase. About 66.7％ and 69.3％ of Acinetobacter (A. baumannii accounts for 91.5％) strains were resistant to imipenem and meropenem, respectively. Compared with the data of year 2016, P. aeruginosa strains showed decreasing resistance rate to carbapenems. Conclusions Bacterial resistance is still on the rise. It is necessary to strengthen hospital infection control and stewardship of antimicrobial agents. The communication between laboratorians and clinicians should be further improved in addition to surveillance of bacterial resistance.
