Objective:To understand the infection status and molecular types of rhinovirus (RV) among cases of Acute Respiratory Infections (ARIs) in Luohe City, Henan Province, from 2017 to 2022.Methods:From October 2017 to June 2022, clinical and epidemiological data were collected from 2 270 cases of ARIs at Luohe Central Hospital in Henan Province. Throat swab specimens were obtained from these cases. Real-time quantitative polymerase chain reaction (qPCR) was used to screen for RV-positive specimens. Subsequently, the positive samples were subjected to nested reverse transcription polymerase chain reaction (nested RT-PCR) to amplify the full-length VP1 region. Using the MEGA software, along with 169 RV reference strains recommended by the International Committee on Taxonomy of Viruses, a phylogenetic tree was constructed to determine RV types.Results:Among the 2 270 cases of ARIs, there were 1 283 male cases (56.52%). The median age ( Q 1, Q 3) was 3 (1, 6) years, with the population under 5 years old accounting for 68.59% (1 557/2 270). RV was detected in 137 cases (6.04%), of which 68 cases (49.64%) showed co-detection with other viruses, with the most common being co-detection with enterovirus, accounting for 14.60% (20/137). The RV detection rates in the age groups of 0-4 years, 5-14 years, 15-59 years, and≥60 years were 6.42% (100/1 557), 4.69% (21/448), 3.80% (6/158), and 9.35% (10/107), respectively, with no statistically significant differences ( χ2=5.310, P=0.150). The overall detection rates of RV before (2017-2019) and during (2020-2022) the COVID-19 pandemic showed no statistically significant difference ( χ2=1.823, P=0.177). A total of 109 VP1 sequences were obtained, including 62 types. Among them, RV-A, RV-B, and RV-C had 42, 3, and 17 types respectively. Conclusion:RV is one of the predominant pathogens in ARIs cases in Luohe City, Henan Province, from 2017 to 2022. Multiple types of RV co-circulate without any apparent dominant type.

Background::Dual-energy computed tomography (DECT) is purported to accurately distinguish uric acid stones from non-uric acid stones. However, whether DECT can accurately discriminate ammonium urate stones from uric acid stones remains unknown. Therefore, we aimed to explore whether they can be accurately identified by DECT and to develop a radiomics model to assist in distinguishing them.Methods::This research included two steps. For the first purpose to evaluate the accuracy of DECT in the diagnosis of uric acid stones, 178 urolithiasis patients who underwent preoperative DECT between September 2016 and December 2019 were enrolled. For model construction, 93, 40, and 109 eligible urolithiasis patients treated between February 2013 and October 2022 were assigned to the training, internal validation, and external validation sets, respectively. Radiomics features were extracted from non-contrast CT images, and the least absolute shrinkage and selection operator (LASSO) algorithm was used to develop a radiomics signature. Then, a radiomics model incorporating the radiomics signature and clinical predictors was constructed. The performance of the model (discrimination, calibration, and clinical usefulness) was evaluated.Results::When patients with ammonium urate stones were included in the analysis, the accuracy of DECT in the diagnosis of uric acid stones was significantly decreased. Sixty-two percent of ammonium urate stones were mistakenly diagnosed as uric acid stones by DECT. A radiomics model incorporating the radiomics signature, urine pH value, and urine white blood cell count was constructed. The model achieved good calibration and discrimination {area under the receiver operating characteristic curve (AUC; 95% confidence interval [CI]), 0.944 (0.899–0.989)}, which was internally and externally validated with AUCs of 0.895 (95% CI, 0.796–0.995) and 0.870 (95% CI, 0.769–0.972), respectively. Decision curve analysis revealed the clinical usefulness of the model.Conclusions::DECT cannot accurately differentiate ammonium urate stones from uric acid stones. Our proposed radiomics model can serve as a complementary diagnostic tool for distinguishing them in vivo.

ObjectiveTo determine the antibody levels of varicella-zoster virus （VZV） in healthy individuals aged 1 to 30 years in Songjiang District of Shanghai， and to provide evidence for further development of varicella immunization strategies for healthy population. MethodsSix village committees were selected in Songjiang District through multi-stage stratified random sampling method from July to September 2022. Healthy individuals aged 1 to 30 years old in these villages were recruited and 3‒5 mL of venous blood was collected. Anti-VZV IgG antibody was tested by ELISA. Positive rate of anti-VZV IgG antibody and geometric mean concentration （GMC） were determined. ResultsA total of 315 healthy individuals aged （10.97±8.38） years were included in this study， of which 165 were males aged （11.00±8.52） years and 150 were females aged （10.96±8.25） years. Blood samples were collected and tested for anti-VZV IgG antibody， with the overall positive rate of 55.24% （174/315）. The GMC was calculated to be 99.73 mIU·mL^-1， with the GMC in those tested positive for anti-VZV IgG antibody of 413.11 mIU·mL^-1. The positive rate of anti-VZV IgG antibody and GMCs across age groups ranged between 13.33%‒86.67% and 16.36‒355.14 mIU·mL^-1， respectively. The highest GMC was found in the group of 20‒30 years old （355.14 mIU·mL^-1）， followed by 132.41 mIU·mL^-1 in the group of 5‒ years old and 138.12 mIU·mL^-1 in the group of 15‒ years old. Moreover， the positive rate was 38.47% in the group with 1-dose varicella vaccine and 63.49% in the group with 2 doses， while the GMC were 53.28 mIU·mL^-1 and 130.79 mIU·mL^-1 in these two groups， respectively. Multivariable analysis revealed that occupation was a risk factor associated with anti-VZV IgG antibody （OR=2.540）. Stratified analysis by varicella immunization history showed that among 2-dose vaccination group， time interval since the last dose was a protective factor （OR=0.315）. ConclusionsThe overall positive rate of anti-VZV IgG antibody in healthy population in Songjiang District of Shanghai remains low. The 2-dose varicella vaccination should be strengthened to improve the coverage in susceptible population.

YABBY proteins are important transcription factors that regulate morphogenesis and organ development in plants. In order to study the YABBY of strawberry, bioinformatic technique were used to identify the YABBY gene families in Fragaria vesca (diploid) and Fragaria×ananassa (octoploid), and then analyze the sequence characters, phylogeny and collinearity of the family members. The RNA-seq data and the quantitative reverse transcription-polymerase chain reaction (qRT-PCR) technique were used to assay the expression patterns of the family members. A green fluorescent protein (GFP) was fused with FvYABBYs and transiently expressed in tobacco leaf cells for the subcellular localization. As the results, six FvYABBY genes and 26 FxaYABBY genes were identified from F. vesca and F.×ananassa, respectively. The FvYABBY genes were grouped into five clades, and five family members were orthologous with AtYABBY genes of Arabidopsis. In F. vesca, all of the FvYABBYs were basically not expressed not expressed in root and receptacle, while FvYABBY1, FvYABBY2, FvYABBY5 and FvYABBY6 were highly expressed in leaf, shoot, flower and achene. In F.×ananassa, FxaYABBY1, FxaYABBY2, FxaYABBY5 and FxaYABBY6 were expressed in achene, and all FxaYABBY were poorly or not expressed in receptacle. Additionally, under the abiotic stresses of low temperature, high salt and drought, the expression of FvYABBY1, FvYABBY3, FvYABBY4 and FvYABBY6 were down-regulated, FvYABBY5 was up-regulated, and FvYABBY2 was up-regulated and then down-regulated. In tobacco leaf cells, the subcellular localization of FvYABBY proteins were in the nucleus. These results provides a foundation for the functional researches of YABBY gene in strawberry.

SUN gene is a group of key genes regulating plant growth and development. Here, SUN gene families of strawberry were identified from the genome of the diploid Fragaria vesca, and their physicochemical properties, genes structure, evolution and genes expression were also analyzed. Our results showed that there were thirty-one FvSUN genes in F. vesca and the FvSUNs encoded proteins were classified into seven groups, and the members in the same group showed high similarity in gene structures and conservative motifs. The electronic subcellular localization of FvSUNs was mainly in the nucleus. Collinearity analysis showed that the members of FvSUN gene family were mainly expanded by segmental duplication in F. vesca, and Arabidopsis and F. vesca shared twenty-three pairs of orthologous SUN genes. According to the expression pattern in different tissues shown by the transcriptome data of F. vesca, the FvSUNs gene can be divided into three types: (1) expressed in nearly all tissues, (2) hardly expressed in any tissues, and (3) expressed in special tissues. The gene expression pattern of FvSUNs was further verified by quantitative real-time polymerase chain reaction (qRT-PCR). Additionally, the seedlings of F. vesca were treated by different abiotic stresses, and the expression level of 31 FvSUNs genes were assayed by qRT-PCR. The expression of most of the tested genes was induced by cold, high salt or drought stress. Our studies may facilitate revealing the biological function and molecular mechanism of SUN genes in strawberry.

Objective:To explore the mechanism of Shuerjing Capsule in treating primary dysmenorrhea based on molecular docking of network pharmacology and in vivo experiment.Methods:By using TCMSP to screen the active components and targets of Shuerjing Capsule; by using GeneCards and DrungBank databases to retrieve targeted proteins of primary dysmenorrhea, and the intersection targets of drugs and diseases were obtained through Weishengxin online platform; by using Cytoscape 3.9.1 software to produce component-target network of Shuerjing Capsule for the treatment of primary dysmenorrhea; by STRING databases to construct drug-disease target PPI network; by DAVID database to perform GO and KEGG pathway enrichment analysis.The key active components of the drug and the core targets of the disease were obtained with molecular docking. The rats were randomly divided into control group, model group, the low-dose group, medium-dose group and high-dose group of Shujing Capsule (0.15, 0.21, 0.42 g/kg), and ibuprofen group (20 mg/kg), with 10 rats in each group. The animal model of primary dysmenorrhea was established by subcutaneous injection of estradiol benzoate and intervented by drugs. The number of writhing reaction, uterine contractile inhibition rate and uterine index of rats were observed. The expressions of TNF-α, IL-6 and IL-1 in serum and the levels of PTGS2 and VEGFA in uterine tissue were detected by ELISA.Results:A total of 188 active ingredients of Shuerjing Capsule were screened, and 51 targets of Shuerjing Capsule and primary dysmenorrhea were identified. TNF, IL-6, AKT1 and TP53 may be the key targets of Shuerjing Capsule in the treatment of primary dysmenorrhea. A total of 519 GO biological processes and 119 related signaling pathways were obtained, among which estrogen, IL-17, HIF-1 and other signaling pathways were closely related to the treatment of primary dysmenorrhea. The results of molecular docking were good, among which stigmasterol had the strongest binding ability to TP53. The experimental results showed that compared with the model group, the uterine index and the number of torsion were decreased in the low -, medium - and high-dose Shuojing Capsule groups ( P<0.05), the uterine contraction inhibition rate increased ( P<0.05); Serum levels of TNF-α, IL-6 and IL-1 of medium and high dose group decreased ( P<0.05), the levels of PTGS2 and VEGFA in uterine tissues decreased ( P<0.05). Conclusion:Shuerjing Capsule has the effect of anti-inflammatation and improveing hypoxia, which may be related to the inhibition of TNF-α, IL-6 and IL-1 inflammatory factors in serum and the expression of PTGS2 and VEGFA proteins in uterine tissues.
