Objective: To learn the characteristics of varicella breakthrough cases aged under 14 years in Haizhu District, Guangzhou City and the effects of vaccination on incidence of breakthrough cases, so as to provide the basis for improving varicella vaccination strategy. Methods: Data of varicella cases aged under 14 years and vaccination in Haizhu District were collected through Chinese Disease Prevention and Control Information System and Guangdong Provincial Vaccination and Vaccine Circulation Management Information System from 2015 to 2022. Temporal distribution, population distribution and vaccination history of varicella breakthrough cases were descriptively analyzed. Effects of primary immunization age and inoculation interval on breakthrough interval were analyzed using least square method fitting bi-cubic functional equation. Results: A total of 4 008 varicella breakthrough cases aged under 14 years were reported in Haizhu District from 2015 to 2022, accounting for 29.16% of all varicella cases. There were mainly 1-dose breakthrough cases, with 3 607 cases accounting for 90.00%. The proportion of 1-dose breakthrough cases showed a downward trend, while the proportion of 2-dose breakthrough cases showed an upward trend (both P<0.05). The epidemics peaked from March to May and from November to January, with a male-to-female ratio of 1.41︰1. The age of onset was mainly at 4 to 6 years, with 1 189 cases accounting for 29.67%. The primary immunization age was mainly ranged from 12 to <24 months, with 2 662 cases accounting for 66.42%. Vaccination of the second dose was concentrated at the age of 48 to <60 months, with 136 cases accounting for 33.92%. The breakthrough interval was relatively long among cases with primary immunization age at 12 to <36 months and inoculation interval within 45 months, with a median breakthrough interval of 25.24 (interquartile range, 20.00) months. Primary immunization age and inoculation interval were negatively correlated with breakthrough interval (P<0.05). Conclusions The varicella breakthrough cases aged under 14 years in Haizhu District from 2015 to 2022 were mainly occurred at the beginning of the new term, with a high incidence among preschool children. It is recommended that children receive the first dose of varicella vaccine within 36 months of age and booster within 45 months of interval.

Objective To observe the regulation of Panx1 on ATP/IP3 signaling pathway and its mechanism during cisplatin-induced apoptosis of lung adenocarcinoma cells. Methods Human lung adenocarcinoma cell line A549 was used as the research object and carbenoxolone (CBX) was used as a drug interference tool. A549 cells were divided into normal control group, the CBX group, the cisplatin (DDP) group and the CBX+DDP group. MTT assay and Annexin V/PI assay were used to detect the survival and apoptosis rates of A549 cells. The relative concentrations of extracellular adenosine triphosphate (ATP) and intracellular inositol triphosphate (IP3) were measured by Chemiluminescence and ELISA. Results Compared with DDP group, the cell survival rate of CBX+DDP group increased, while the early and late apoptotic rates and the release concentration of extracellular ATP and intracellular IP3 decreased (all P < 0.01). Conclusion Panx1 can increase the sensitivity of lung adenocarcinoma cells to cisplatin by regulating the ATP/IP3 signaling pathway.

Objective To evaluate the influences of susceptibility interpretation of Escherichia coli,Klebsiella pneumonia and Proteus mirabilis in China mainland according to the old and new ceftazidime,cefotaxime and ceftriaxone breakpoints in CLSI M100-S20 and CLSI M100-S19. Methods First, We analyzed the antibacterial susceptibility results of the three bacteria by agar dilution method in the SEANIR surveillance item, which were collected from 15 national hospitals between the year of 2005 and 2007 and excluded the AmpC enzyme positive isolates according to the PGR-DNA sequencing method and/or the antibacterial susceptibility phenotype. ESBL phenotype was confirmed by the CLSI phenotypic confirmatory test. Antibacterial susceptibility of the total 2733 Escherichia coli, Klebsiella pneumonia, Proteus mirabilis isolates was retrospectively analyzed by WHONET 5. 4 software according to the breakpoints of the CLSI M100-S19 (S19) and CLSI M100-S20 (S20). Second, 207 isolates of Peking Union Medical College Hospital with the results of both agar dilution method and disk diffusion method were performed by recurrent analysis. Then we observed the inter-method agreement through the scatter diagram according to the breakpoints of S19 and S20. Results First, as to the ESBL positive Escherichia coli, Klebsiella pneumonia and Proteus mirabili.s, the resistant rate of cefotaxime increased from 65.2% , 55.5%, 14. 6% under S19 (64 μg/ml) to 99. 7%, 96. 2% , 93. 8% under S20 (4 μg/ml). The susceptibility rates decreased from 6. 0%, 11.5%, 33.3% under S19 (8 μg/ml) to 0%, 0. 2%, 0% under S20 ( 1 μg/ml). Ceftriaxone had the same trend as cefotaxime. Though ceftazidime was more active than cefotaxime and ceftriaxone, as to the ESBL positive Escherichia coli and Klebsiella pneumonia, the resistant rates slightly increased from 30. 3%,43. 2% under S19 (32 μg/ml) to42.0%, 56. 0% under S20 (16 μg/ml). The susceptibility rates slightly decreased from 58. 1%, 44. 1% under S19 (8 μg/ml) to 44. 7%, 28.0% under S20 (4 μg/ml). Second,as to the ESBL negative Escherichia coli, Klebsiella pneumonia and Proteus mirabilis, all the susceptibility rates of ceftazidime, cefotaxime and ceftriaxone were between 99. 2%-100. 0%, the resistant rate were between 0%-0. 4%. Third, the S20 MIC breakpoints had a good correspondence with the ESBL phenotype.Fourth, according to the recurrent analysis of MIC testing and disk dilution method, r value was 0. 67,0. 79, 0. 77 for ceftazidime, cefotaxime and ceftriaxone, respectively, and all P value were under 0. 01. The intermethod rates of S19 and S20 were both acceptable. Conclusions If the cefotaxime and ceftriaxone S20 new breakpoints were used, the concordance of antibacterial susceptibility results and ESBL phenotype would increase greatly. The clinician could select proper antibiotics according to the antibacterial susceptibility results and clinical symptoms. It is no longer necessary to edit results for cephalosporins, aztreonam, or penicillins from susceptible to resistant. However, until laboratories implement the new interpretive criteria,ESBL testing should be performed as described in Supplemental Table 2A-S1. The relationship between the new breakpoints of ceftazidime and clinical outcomes need to be further evaluated.
