ObjectiveTo explore the mechanism by which Qidan Yifei Tongqiao granules （QDYF） alleviate nasal mucosal remodeling in allergic rhinitis （AR） via the interleukin-33 （IL-33）/growth stimulation expressed gene 2 （ST2）/interleukin-1 receptor accessory protein （IL-1RAP） signaling pathway from the perspective of Qi-replenishing and blood-activating therapy. MethodsFirst， according to the previous network pharmacology results， this study predicted the potential mechanisms of QDYF in treating AR by screening key pathways， components， and targets. Molecular docking was performed via AutoDock and PyMOL 2.5.5. Subsequently， a rat model of ovalbumin （OVA）-induced AR was used for validation through in vivo experiments. Forty-eight rats were assigned into 6 groups： Control， model， low-dose QDYF （QDYF-L， 4.04 g·kg^-1）， medium-dose QDYF （QDYF-M， 8.08 g·kg^-1）， high-dose QDYF （QDYF-H， 16.16 g·kg^-1）， and loratadine （0.9 mg·kg^-1）. After 14 days of intervention， behavioral scores of the rats were observed. The morphological changes of nasal mucosa tissue were observed by hematoxylin-eosin （HE） staining. Masson staining was used to observe collagen fiber deposition in the nasal mucosal tissue and to calculate the collagen volume fraction （CVF）. The expression of E-cadherin （E-cad） in the nasal mucosa tissue was detected by immunofluorescence. The serum levels of helper T cell 2 （Th2） cytokines interleukin-4 （IL-4）， interleukin-5 （IL-5）， and interleukin-13 （IL-13） as well as helper T cell 1 （Th1） cytokines interleukin-2 （IL-2） and interferon-γ （INF-γ） were quantified by enzyme-linked immunosorbent assay （ELISA）. The protein levels of transforming growth factor-beta 1 （TGF-β₁）， IL-33， ST2， and IL-1RAP in the nasal mucosa tissue were determined by Western blot. ResultsIL-33， ST2， and IL-1RAP had strong binding ability with the main active ingredients—wogonin， 7-methoxy-2-methylisoflavone， formononetin， naringenin， stigmasterol， and beta-sitosterol of QDYF， with the binding energy < -4.25 kcal⋅mol^-1（1 cal≈4.184 J）. The results of in vivo experiments showed that compared with the control group， the model group exhibited increased behavioral scores （P<0.05）， aggravated pathological damage of nasal mucosa， increased collagen fiber deposition and CVF （P<0.05）， elevated serum levels of IL-4， IL-5， and IL-13， up-regulated protein levels of TGF-β₁， IL-33， ST2， and IL-1RAP in the nasal mucosa （P<0.05）， down-regulated expression of E-cad， and declined serum levels of IL-2， IFN-γ， and IFN-γ/IL-4 ratio （P<0.05）. Compared with the model group， the QDYF groups and loratadine group showed reduced behavioral scores （P<0.05）， alleviated pathological damage of nasal mucosa， reduced collagen fiber deposition and CVF （P<0.05）， and up-regulated E-cad expression （P<0.05）. Compared with the model group， the QDYF-H group and the loratadine group showed raised levels of INF-γ and IFN-γ/IL-4 ratio （P<0.05）， declined serum levels of IL-4， IL-5， and IL-13， and down-regulated protein levels of TGF-β₁， IL-33， ST2， and IL-1RAP in the nasal mucosa （P<0.05）. In addition， the QDYF-H group exhibited an elevated serum IL-2 level （P<0.05）. The QDYF-M group showed down-regulated protein levels of TGF-β₁， IL-33 and IL-1RAP in the nasal mucosa （P<0.05）. The QDYF-L group demonstrated a down-regulated protein level of ST2 in the nasal mucosa （P<0.05）. ConclusionQDYF may regulate the Th1/Th2 balance through the IL-33/ST2/IL-1RAP signaling pathway， thereby ameliorating nasal mucosal tissue remodeling and alleviating AR.

The scientific interpretation of the theory of medicinal properties of TCM is a research hotspot in the modernization of TCM. It is of great value to clarify the property and degree of cold and heat in Chinese materia medica for guiding clinical precise medication. In recent years, the research on the cold and heat properties of Chinese materia medica has been carried out at the animal, cell and molecular levels. Based on the objective material basis of medicinal properties, from the perspective of biological effects such as thermodynamics and multiomics; with the help of infrared thermal imaging and other technologies for analysis; forming a variety of research models such as "property-structure relationship". Related research has developed from a single material component or index to a new model that tends to integrate multi-source information and multi-dimensional data. However, how to deal with the problems of large sample size, strong redundancy, high heterogeneity, and how to integrate multi-dimensional information are still research difficulties. With its powerful computing and learning ability, machine learning can show good discrimination and prediction ability in the study of cold and hot properties of Chinese materia medica, and play an important role in the study of cold and hot properties of Chinese materia medica. At present, the most widely used algorithms are linear discriminant analysis, Logistic discriminant analysis, support vector machine, decision tree, random forest and so on. The data dimension of the existing research needs to be enriched, the algorithm has room for further optimization, and a more detailed discriminant model of cold and hot properties of Chinese materia medica needs to be established.

Objective:To analyze the epidemiological features of respiratory syncytial virus (RSV) infection in Beijing, and monitor the sequence variations in RSV glycoprotein (G) gene and clinical features of infected children.Methods:Respiratory tract specimens were collected from children with acute respiratory infection in the Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 1, 2023 to December 31, 2023. RSV-positive specimens screened by multiple nucleic acid testing were subjected to PCR to amplify the full-length RSV G gene. A phylogenetic tree was constructed after gene sequencing to analyze RSV subtypes and trace G gene variants. Clinical data were retrieved from the medical record system to analyze the clinical features of children with RSV infection in Beijing.Results:A total of 5 489 respiratory specimens were collected from 3 046 male patients and 2 443 female patients. The average age of the patients was 4.36 years. A total of 589 RSV-positive specimens (10.7%, 589/5 489) were detected with 349 from male patients and 240 from female patients. The average age of children with RSV infection was (2.51±2.78) years and the median age was 0.48 years. RSV had been circulating among children in Beijing since March 2023 with two epidemic peaks in May (24.6%, 122/496) and December (18.2%, 126/693). The predominant subtype of RSV in the first half of 2023 was subtype A, but it was replaced by subtype B from November 2023. Phylogenetic analysis revealed a novel G gene of RSV subtype B (RSV-B-BA9-954bp) with a length of 954 bp, which belonged to a new cluster in the phylogenetic tree. The percentage of patients admitted to the Intensive Care Unit (ICU) was higher in children with new variant of RSV subtype B infection than in those with common RSV subtype B infection [44.1% (15/34) vs 25.2% (31/123), χ 2=4.600, P=0.032], while the counts of white blood cells and the levels of C-reactive protein were lower in the children with new variant infection ( P<0.05). Conclusions:RSV has been prevalent among children in Beijing since March 2023 with two epidemic peaks. The predominant A subtype is gradually replaced by to B subtype. A new variant of RSV B G gene (RSV-B-BA9-954bp) is detected among the children.

Objective:To analyze the differentially expressed genes of human respiratory syncytial virus (RSV) subtype A genotype ON1, a predominant genotype in Beijing, after infecting A549 cells using transcriptomic sequencing, and provide potential targets for RSV prevention and treatment.Methods:A local strain (61397-ON1) identified by whole-genome sequencing as ON1 genotype of RSV subtype A was selected to infect A549 cells. Total mRNA was extracted, and the differentially expressed genes in infected and uninfected A549 cells were screened by transcriptomic sequencing. GO analysis and KEGG pathway analysis were performed. Besides, six genes with differential expression ratio greater than two times were randomly selected for qRT-PCR verification.Results:There were 1 632 differentially expressed genes between infected and uninfected A549 cells, of which 807 genes were up-regulated and 825 genes were down-regulated. The differentially expressed genes were mainly involved in immune response-related biological processes such as cytokine response and positive regulation of MAPK cascades, and were enriched in MAPK signaling pathway, NOD-like receptor signaling pathway, p53 signaling pathway, TNF signaling pathway, IL-17 signaling pathway and NF-κB signaling pathway. The results of qRT-PCR for six differentially expressed genes were consistent with the trend of transcriptome data.Conclusions:The differentially expressed genes of RSV A subtype ON1 genotype after infecting A549 cells are mainly involved in cytokine response and immune-related signaling pathways. This study provides basic data for further study of the molecular mechanism of RSV infection and the development of prevention and treatment strategies.

Objective To explore the predictive value of systolic pulmonary artery pressure (SPAP) on autonomic nerve excitation in patients with valvular disease, so as to provide reference for the formulation of clinical intervention plans. Methods The clinical data of patients with valvular disease who received surgical treatment in the General Hospital of Northern Theater Command from August 28, 2020 to February 3, 2021 were prospectively collected. According to the standard deviation of normal-to-normal R-R intervals (SDNN) of the heart rate variability (HRV) of the long-range dynamic electrocardiogram (ECG) 7 days before the operation, the patients were divided into three groups: a sympathetic dominant (SE) group (SDNN≤50 ms), a balance group (50 ms

Objective To evaluate the short-term results of sleeve wrapping technique using remnant aortic wall in modified Bentall procedure. Methods The patients undergoing modified Bentall procedure with the remnant aortic wall as a sleeve to cover the sewing area of composite valved graft and the aortic annulus for proximal hemostasis between March 2021 and March 2022 in Shenzhen Fuwai Hospital were enrolled. Short-term results were assessed by cardiopulmonary bypass time, aortic clamping time, mechanical ventilation time, ICU stay, postoperative hospital stay, effusion drainage on the first postoperative day, left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter (LVEDD), and follow-up results. Results A total of 14 patients were collected, including 12 males and 2 females, with a mean age of 55.33±10.57 years. There was no postoperative or follow-up death. Cardiopulmonary bypass time was 147.90±21.29 min, aortic clamping time was 115.70±15.23 min, mechanical ventilation time was 19.42±8.98 h, ICU stay was 99.08±49.42 h, and postoperative hospital stay was 16.33±2.74 d. Thoracic drainage volume was 333.33±91.98 mL on the first postoperative day. Only 2 patients required blood transfusion (4.5 U and 2 U, respectively). During the follow-up of 6.17±3.69 months, there was no death, no aortic or valve-related complications. There was statistical difference in the LVEDD between preoperation and before discharge after surgery (P＜0.001), and between half a year after surgery and before discharge after surgery (P＜0.001). There was a little decrease of LVEF before discharge after surgery compared with preoperative LVEF, but there was no statistical difference (P=0.219). There was no statistical difference in the LVEF half a year after operation compared with that before operation (P=1.000). Conclusion Sleeve wrapping technique using remnant aortic wall in modified Bentall procedure has good short-term results. This modification may be a simple, effective way in controlling proximal bleeding.
