[Objective] To investigate the factors associated with alanine aminotransferase (ALT) abnormalities in multi-ethnic blood donors across five Zang autonomous prefectures in the plateau regions of Qinghai Province, and to provide evidence for ensuring blood safety and formulating screening strategies. [Methods] A retrospective analysis was performed on the ALT abnormal test results of blood donors in the Zang autonomous prefectures of Qinghai from 2022 to 2024. The correlations between ALT levels and factors including gender, age, altitude, and infectious markers were investigated. [Results] The overall ALT unqualified rate among blood donors in this region was 9.01%. Significant differences in ALT levels were observed across genders and age groups (P<0.05). Variations in ALT abnormality rates were also noted among different plateau regions (P<0.05). Overall, ALT values exhibited an increasing trend with rising altitude. The average ALT unqualified rates were 11.19% in Zang donors, 7.96% in Han donors, and 4.79% in donors from other ethnic groups (P<0.05). No statistically significant association was observed between ALT abnormality and the presence of HBV/HCV infectious markers (P>0.05). [Conclusion] In the plateau areas of Qinghai, multi-ethnic blood donors have a relatively high ALT levels and ALT unqualified rates, showing distinct regional characteristics. ALT elevation in voluntary blood donors is related to non-pathological factors such as gender, age, and dietary habits, but not to infectious indicators.

Objective:To recheck the Histoplasma capsulatum and Coccidioides sp. strains of the past by molecular identification and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS). Methods:The phylogenetic relationships among the ten Histoplasma capsulatum isolates and reference strains were analyzed by multilocus sequence typing (MLST). Based on the Coi region, Coccidioides posadasii was distinguished from Coccidioides immitis accurately. MALDI-TOF MS was used to set up the MALDI-TOF MS database of Histoplasma capsulatum and Coccidioides sp. for rapid identification. In addition, hierarchical clustering of spectra was compared with MLST. Results:An unrooted dendrogram constructed with MLST showed that ten individuals of Histoplasma capsulatum were divided into three clades: Eurasia clade, Australia clade and North American class 2 clade, in agreement with the establishment by MALDI-TOF MS cluster analysis. All individuals of Coccidioides sp. were identified as Coccidioides posadasii with Coi region primers. The in-house MALDI-TOF MS database of Histoplasma capsulatum and Coccidioides posadasii was expanded and reached an identified accuracy of 100%. Conclusions:We improve the recognition of Histoplasma capsulatum and Coccidioides posadasii by molecular pathways which shows the major species or clades in Chinese mainland. The in-house MALDI-TOF MS database of Histoplasma capsulatum and Coccidioides posadasii can provide a new efficient way to identify those pathogens rapidly.

Objective:To investigate the diagnostic value of lung ultrasound in hospitalized children with community-acquired pneumonia (CAP).Methods:In the cross-sectional study, a total of 422 children with CAP who were hospitalized in the Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University, from February 2021 to August 2022 and completed lung ultrasound examination within 48 hours after admission were enrolled. The clinical characteristics, lung ultrasound and chest CT were collected. The patients were divided into two groups according to the signs of pneumonia indicated by chest CT, and the signs of lung ultrasound with diagnostic value were screened according to the signs of pneumonia indicated by chest CT by least absolute shrinkage and selection operator (Lasso) regression. According to severity of the disease, the children were divided into the severe group and the mild group, and the differences of lung ultrasound signs between the two groups were compared. Kruskal-Wallis test, Fisher′s exact test was selected for comparison between groups. Random forest classifier wes used to evaluate the value of lung ultrasound in the diagnosis of CAP and prediction of severe pneumonia in children. The receiver operating characteristic curve was used to evaluate the prediction effect. Use DeLong test to compare the area under the curve.Results:Among the 422 cases of CAP, there were 258 males and 164 females, and the age of onset was 2.8 (1.3, 4.3) years. The confluent B-line, consolidation and pleural effusion detected by lung ultrasound were 309 cases (73.2%), 232 cases (55.0%) and 16 cases (3.8%), respectively, and the size of consolidation was 3.0 (0, 11.0) mm. One hundred and ten children (26.1%) with CAP completed chest CT. There were 90 cases with signs of pneumonia in chest CT and 20 cases without signs of pneumonia. Lasso was used for feature selection.Lung consolidation ( OR=2.46), bilateral lung consolidation ( OR=1.16) and confluent B-line ( OR=1.34) were the main index. With random forest classifier, the accuracy of models using full variables and Lasso-selected variables were 0.79 (95% CI 0.70-0.86) and 0.79 (95% CI 0.70-0.86), the sensitivity were 0.81 and 0.81, and the specificity were 0.75 and 0.70, and the area under curve were 0.87 (95% CI 0.81-0.94, P<0.001) and 0.84 (95% CI 0.76-0.91, P<0.001), respectively. There were 97 cases in severe group and 325 cases in mild group. Compared with the mild group, the detection rate of consolidation, multiple consolidation, the size of consolidation and the size of consolidation was adjusted by body surface area (consolidation size/body surface area) in severe group were higher (66 cases (68.0%) vs. 166 cases (51.1%), 42 cases (43.3%) vs. 93 cases (28.6%), 8.0 (0, 17.0) vs. 1.0 (0, 9.0) mm, 12.5 (0, 24.6) vs. 2.1 (0, 17.6), χ2=8.59, 9.98, Z=14.40, 12.79, all P<0.05). Using lung ultrasound lung consolidation size and consolidation size/body surface area to predict the severe CAP, the optimal cut-off value were 6.7 mm and 10.2, the accuracy was 0.80 (95% CI 0.75-0.83) and 0.89 (95% CI 0.86-0.92), the sensitivity was 0.99 and 0.99, the specificity was 0.14 and 0.56, respectively, and the area under the curve was 0.66 (95% CI 0.60-0.72, P<0.001) and 0.76 (95% CI 0.70-0.83, P<0.001), respectively. The area under the curve of consolidation size/body surface area was higher than that of consolidation size ( Z=5.50, P<0.001). Conclusions:Consolidation and confluent B-line, are important index for lung ultrasound diagnosis of CAP in children. The actual consolidation size adjusted by body surface area is superior to the size of consolidation in predicting severe CAP.

Objective:To compare the in vitro susceptibility of fluconazole-resistant Candida albicans strains from superficial and deep infections to 8 antifungal drugs, and to compare drug resistance mutations in these strains. Methods:According to the Clinical and Laboratory Standards Institute (CLSI) protocol M27-A4, 26 deep infection-derived and 33 superficial infection-derived drug-resistant Candida albicans strains were tested for in vitro susceptibility to 8 antifungal drugs (fluconazole, voriconazole, itraconazole, posaconazole, amphotericin B, fluorocytosine, terbinafine, and micafungin) alone or in combination. DNA was extracted from all drug-resistant strains, and mutations in 3 drug resistance genes, including ERG3, ERG11 and FUR1, were detected by PCR. Normally distributed measurement data with homogeneous variance were compared between two groups by using two-independent-sample t test, non-normally distributed measurement data with non-homogeneous variance were compared using Mann-Whitney U test, and enumeration data were compared using chi-square test. Results:The minimum inhibitory concentrations (MICs) of fluconazole, itraconazole, voriconazole, posaconazole and fluorocytosine all significantly differed between the superficial infection group and deep infection group (all P < 0.05) , while there was no significant difference in the MIC of amphotericin B or micafungin between the two groups (both P > 0.05) . The MIC of terbinafine was >64 μg/ml in 96.6% of the above strains, so could not be compared between groups. As combination drug susceptibility testing revealed, the combination of terbinafine with azoles (fluconazole, voriconazole, itraconazole or posaconazole) showed synergistic inhibitory effects against 15 Candida albicans strains (7 strains from deep infections, 8 strains from superficial infections) , with fractional inhibitory concentration (FIC) indices being 0.033 to 0.187; no marked synergistic effect was observed in the combinations between fluorocytosine and azoles, between fluorocytosine and amphotericin B, or between amphotericin B and fluconazole, with the FIC indices being 0.56 to 1.125. The missense mutation V351A in the ERG3 gene was identified in all the 33 (100%) superficial infection-derived strains, as well as in 13 (50%) deep infection-derived strains, and the mutation A353T in the ERG3 gene was identified in 4 (15%) deep infection-derived strains; as for the ERG11 gene, missense mutations identified in the superficial infection-derived strains included I437V (32 strains, 97%) , Y132H (23 strains, 70%) , T123I (16 strains, 48%) , K128T (6 strains, 18%) , D116E (5 strains, 15%) , A114S (4 strains, 12%) , E266D (2 strains, 6%) , G448E (2 strains, 6%) , and G465S (2 strains, 6%) , while missense mutations identified in the deep infection-derived strains included I437V (23 strains, 88%) , E266D (13 strains, 50%) , E260G (5 strains, 19%) , and V488I (4 strains, 15%) ; the missense mutation R101C in the FUR1 gene was identified in 11 (33%) superficial infection-derived strains, but not identified in deep infection-derived strains. Conclusion:The drug susceptibility and drug resistance mutations differed to some extent between superficial infection- and deep infection-derived fluconazole-resistant Candida albicans strains.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

Objective:To investigate the predictive value of neutrophil-lymphocyte ratio (NLR) for Trousseau’s syndrome (TS) in patients with acute multiple cerebral infarctions (AMCI).Methods:The patients with AMCI in Suzhou Kowloon Hospital, Shanghai Jiaotong University School of Medicine from July 2013 to March 2022 were retrospectively enrolled. The demographic and baseline clinical data of patients with TS and those without TS were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of TS-AMCI, and receiver operating characteristic (ROC) curve was used to evaluate the predictive value of NLR for TS-AMCI. Results:A total of 59 patients with AMCI were enrolled, including 43 males and 16 females, aged 64.9±14.0 years. There were 16 patients in the TS-AMCI group and 43 in the non-TS-AMCI group. The proportions of patients with diabetes mellitus, hypertension and previous stroke or transient ischemic attack in the TS-AMCI group were significantly lower than those in the non-TS-AMCI group (all P<0.05), while the proportion of patients with ischemic heart disease were significantly higher than that in the non-TS-AMCI group ( P<0.05). The proportion of patients with bilateral infarction in the TS-AMCI group was significantly higher than that in the non-TS-AMCI group ( P<0.001). The D-dimer, NLR, white blood cell count, neutrophil count, monocyte count, percentage of neutrophils, total cholesterol and low-density lipoprotein cholesterol in the TS-AMCI group were significantly higher than those in the non-TS-AMCI group (all P<0.001), while the lymphocyte count, lymphocyte percentage, red blood cell count, hemoglobin and hematocrit were significantly lower than those in the non-TS-AMCI group (all P<0.001). Multivariate logistic regression analysis showed that high NLR was an independent predictor of TS-AMCI (odds ratio [ OR] 2.897, 95% confidence interval [ CI] 1.270-6.527; P=0.011), while high hemoglobin was independently negatively correlated with TS-AMCI ( OR 0.839, 95% CI 0.723-0.975; P=0.022). ROC curve analysis showed that the area under the curve of NLR for predicting TS-AMCI was 0.929 (95% CI 0.831-0.979; P<0.001). When the NLR cutoff value was 4.01, the corresponding Youden index was 0.744. At this time, the sensitivity and specificity were 100% and 74.42% respectively. Conclusion:NLR has high predictive value for TS-AMCI.

Acute respiratory tract infection is the most common infectious disease in children, which seriously threatens children′s health.Rapid and accurate etiological diagnosis is of great significance for the clinical treatment and control of these diseases.Pathogen nucleic acid test was applied and became the main method of respiratory tract infection diagnosis for its high sensitivity and specificity.To regulate the application of pathogen nucleic acid amplification test in respiratory tract infection in children, improve the diagnosis level, expert consensus on nucleic acid amplification test of respiratory pathogens in children was prepared to guide the application and promote pathogens diagnosis ability.
