Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To explore the establishment and effect of short-term training path for prenatal ultrasound diagnosticians in primary hospitals.Methods:A total of 105 trainees from in total 5 batches of the "prenatal ultrasound screening training base" in Chongqing were selected as the research objects, and a combination of multiple teaching methods was used to carry out specialized training for primary prenatal ultrasound screening doctors before and after training. Theoretical examinations and practical operation assessments were performed, and after training, remote image quality control and continuous improvement methods were established for trainees to assess training effectiveness. SPSS 21.0 was used for t test, Wilcoxon test and chi-square test. Results:After training, the results of the theoretical examinations and practical operation examinations of the trainees were higher than those before the training ( P<0.05), and after the completion of the training, the number of trainees who returned to their original units to carry out prenatal ultrasound examination, the average number of prenatal ultrasound examinations per month and the number of referrals to higher prenatal diagnosis centers of each trainee increased significantly ( P<0.05). Conclusion:The establishment of short-term training path for prenatal ultrasound diagnosis can effectively improve the professional theoretical knowledge and practical operation level of prenatal ultrasound doctors in primary hospitals, and greatly solve the problem of technical promotion under the shortage of grassroots hospitals.

Objective:To assess the urethral mobility of normal parous women in China and explore the impacts of related risk factors on it using translabial ultrasound.Methods:Females who met the inclusion criteria in 37 tertiary hospitals from February 2017 to August 2018 were included. All women underwent standardized translabial ultrasound examination and the urethral rotation angle (URA), bladder neck position at maximum Valsalva maneuver (BNP-V) and bladder neck descent (BND) were measured. Questionnaires were used to collect basic information including age, height, weight, body mass index (BMI), past medical history, maternity history, and urinary incontinence related history. Mann-Whitney U test and multiple linear regression analysis were adopted to explore the influences of age, BMI, delivery mode and parity on normal parous women′s urethral mobility. Then, the study subjects were divided into different groups and the corresponding values of URA, BNP-V and BND were compared. Results:Compared with parous women with normal BMI and no history of vaginal delivery, those who were overweight and/or had a history of vaginal delivery were more likely to gain greater URA and BND ( P<0.05). The URA and BND were not significantly different between women with different times of cesarean sections ( P>0.05); while for women with a history of vaginal delivery, these two parameters increased with the increase of the number of transvaginal deliveries ( P<0.05). Conclusions:BMI and vaginal delivery are important risk factors for the urethral mobility of normal parous women. The urethral mobility increases with the increase of BMI and the number of vaginal deliveries.

Objective:To investigate the pathogenic characteristics of viral encephalitis or meningitis in children living in Shijiazhuang city and surrounding areas, and to study the relationship between pathogenic and clinical findings.Methods:A total of 132 cerebrospinal fluid specimens were randomly collected from hospitalized children diagnosed with viral encephalitis or meningitis (January 2018 to December 2018) in the Department of Neurology of Hebei Children′s Hospital in Shijiazhuang city and surrounding areas. The nucleic acids of four viruses in cerebrospinal fluid were detected by real-time quantitative PCR. SPSS 21.0 software was used for statistical analysis.Results:Among the 132 cases, 78 were boys and 54 were girls, with a sex ratio of 1.44∶1. However, in the gender composition of children in each age group, there was no significant difference (χ 2=3.901, P=0.272). Of the 132 children, 121 had signs of fever, 109 had symptoms of headache, 92 had symptoms of vomiting, 17 had abnormal electroencephalogram(EEG), and 15 had abnormal head magnetic resonance imaging(MRI). 132 cerebrospinal fluid specimens were tested for pathogenic pathogens, and 80 of them were successfully detected. There was 1 case of human herpesvirus type I(HHV-I), 2 cases of varicella-zoster virus (VZV) and 77 cases of enterovirus(EV). The age group of 1~3 years′s EV detection rate was 66.67%, it is the highest, but overall, the EV detection rate, there was no significant difference among the four age groups (χ 2=3.147, P=0.369). The detection rate of EV in summer and autumn were 65.52% and 70.83%, respectively, which were significantly higher than those in spring and winter (33.33% and 0.00%), and there was a significant difference (χ 2=22.504, P=0.000). There was no significant difference in the positive rates of fever, headache and vomiting between EV-positive and non-EV-positive children ( P>0.05). There was no significant difference in the incidence of abnormal EEG and abnormal head MRI between EV-positive and non-EV-positive children ( P>0.05). Conclusions:In 2018, EV was the main pathogen of viral encephalitis and meningitis in children in Shijiazhuang city and surrounding areas, and EV detection rate was high in summer and autumn.

Subject To compare the irradiation-induced injury and clinical efficacy between SIB-IMRT and LB-IMRT for early-stage breast cancer after breast-conserving surgery.Methods:From November 2002 to February 2012, 353 early breast cancer patients who underwent IMRT after breast-preserving surgery at Shandong Cancer Hospital were selected, of whom 218 patients receiving SIB-IMRT and 135 patients receiving LB-IMRT.The prescription dose of the SIB-IMRT group was the ipsilateral breast (PTV b ) 1.8-1.9 Gy, 27-28 times, and concurrent tumor bed (PTV t) 2.15-2.3 Gy, 27-28 times. In the LB-IMRT group, the prescription dose was PTV b 2.0 Gy, 25 times, followed by PTV t boost 2.0 Gy, 5-8 times. Results:The median follow-up time was 92 months. The excellent, good, fair, and poor cosmetic results in the SIB-IMRT and LB-IMRT groups were 10.1% and 12.6%, 85.8% and 80.7%, 3.7% and 5.2%, 0.5%, and 0.7%, respectively ( P=0.731). The 5-year locoregional recurrence rates (LRRs) in the SIB-IMRT and LB-IMRT groups were 3.21% and 5.93% and the 10-year LRRs were 4.13% and 6.67%, respectively ( P=0.209, 0.280). The 3-, 5-, 8-, and 10-year overall survival rate in the SIB-IMRT and LB-IMRT groups were 97.7% and 97.8%, 96.3% and 95.2%, 94.9% and 92.0%, 93.6% and 90.3%, respectively ( P=0.288). The 3-, 5-, 8-, and 10-year disease-free survival in the SIB-IMRT and LB-IMRT groups were 95.4% and 93.8%, 91.8% and 87.7%, 89.9% and 84.1%, 89.0% and 82.1%, respectively ( P=0.160). Conclusion:There is no significant difference in the cosmetic effect, local control rate, and survival rate between SIB-IMRT and LB-IMRT after breast-preserving surgery in patients with early-stage breast cancer. SIB-IMRT is a safe and feasible treatment.

OBJECTIVE: To explore molecular etiology and clinical characteristics of two pedigrees affected with hereditary factor VII(FVII) deficiency. METHODS: The nine exons and flanking sequences of the F7 gene of the probands were amplified by PCR. The amplicons were analyzed by direct sequencing. Suspected mutations were subjected to SWISS-MODEL modeling and analysis of protein structure change by Pymol software and conservation of amino acids across various species. RESULTS: For proband of pedigree 1, the prothrombin time (PT), FVII activity (FVII:C) and FVII antigen (FVII:Ag) were 36.3 s, 3%, 53.56%, respectively. Sequencing revealed a compound heterozygous variants of c.80_81delCT and c.1371G>T(p.Arg439Ser). His son carried a heterozygous c.1371G>T (p.Arg439Ser) variant. For proband of pedigree 2, the PT, FVII:C and FVII:Ag were 22.3 s, 4%, 1.58%, respectively. Sequencing has revealed a compound heterozygous c.278G>T(p.Arg75Met) missense variant in exon 3 and c.1278T>G (p.His408Gln) in exon 9 of the F7 gene. His mother and son both carried a heterozygous c.278G>T(p.Arg75Met) variant. Three-dimensional simulation and homology analysis revealed that the p.Arg439Ser and p.Arg75Met can respectively alter part of hydrogen bonds and two highly conserved amino acids. CONCLUSION Two novel heterozygous missense variants of the F7 gene [c.1371G>T(p.Arg439Ser) and c.278G>T(p.Arg75Met)] probably account for the decrease of factor VII in the two pedigrees.

Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.
