This study established the HPLC fingerprints, characteristic chromatograms, and a multi-component content determination method for Bidens bipinnata and B. biternata. The chemical pattern recognition analysis was then employed to clarify the characteristic indexes of quality differences between the two original plants of Bidentis Herba, providing a reference for establishing the quality standards of Bidentis Herba. HPLC was launched on an Agilent Poroshell 120 EC-C_(18) chromatographic column(4.6 mm×250 mm, 4 μm) by gradient elution with a mobile phase of 0.1% aqueous phosphoric acid-acetonitrile at a flow rate of 0.7 mL·min~(-1), detection wavelength of 270 nm, column temperature of 25 ℃, and an injection volume of 5 μL. The similarity between the fingerprints of 18 batches of Bidentis Herba samples and the common pattern(R) ranged from 0.572 to 0.933. A total of 23 chromatographic peaks were calibrated. Through comparison with the reference substances, six components(neochlorogenic acid, chlorogenic acid, isochlorogenic acid A, isochlorogenic acid B, rutin, and hyperoside) were identified and subjected to quantitative analysis. The characteristic fingerprints of B. bipinnata and B. biternata were calibrated with 20 and 17 characteristic peaks, respectively. Among them, peaks 8, 9, 22, and 23 were the characteristic peaks of B. bipinnata, and peak 7 was the characteristic peak of B. biternata, which can be used to distinguish the two original plants of Bidentis Herba. The relative standard deviation of the content of the above-mentioned six components ranged from 36% to 123%. The cluster analysis, principal component analysis, and orthogonal partial least squares-discriminant analysis(OPLS-DA) classified the 18 batches of Bidentis Herba samples into two categories. Additionally, through the analysis of variable importance in projection(VIP) under OPLS-DA, three characteristic indexes, rutin, isochlorogenic acid A, and isochlorogenic acid B, were identified. The analytical method established in this study can comprehensively evaluate the consistency of Bidentis Herba samples derived from different original plants, specifically identify the differential components between them, and effectively distinguish the two original plants of Bidentis Herba, providing a basis for the differentiation between different original plants and the quality control of Bidentis Herba.

OBJECTIVES: To investigate the risk factors for the occurrence of cardiopulmonary dysfunction following ligation of hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants. METHODS: A retrospective collection of clinical data was conducted on preterm infants with a gestational age of <34 weeks who were admitted to the Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology from January 2018 to August 2024. These infants underwent hsPDA ligation after 1-2 courses of failed ibuprofen treatment. Based on the occurrence of blood pressure changes and oxygenation or ventilation failure postoperatively, the infants were divided into a cardiopulmonary dysfunction group (19 cases) and a non-cardiopulmonary dysfunction group (40 cases). Binary logistic regression analysis was performed to explore risk factors for postoperative cardiopulmonary dysfunction. RESULTS: Binary logistic regression analysis indicated that a faster average weight gain rate preoperatively and low levels of free triiodothyronine (FT₃) within one week before surgery were risk factors for cardiopulmonary dysfunction following hsPDA ligation (P<0.05). Receiver operating characteristic curve analysis showed that an average weight gain rate >11.45 g/(kg·d) and FT₃ levels <2.785 pmol/L within one week before surgery had predictive value for postoperative cardiopulmonary dysfunction (P<0.05). The combination of these two indicators provided the highest predictive value (P<0.05), with an area under the curve of 0.825, a sensitivity of 79%, and a specificity of 75%. CONCLUSIONS An average weight gain rate exceeding 11.45 g/(kg·d) and FT₃ levels below 2.785 pmol/L within one week before surgery are risk factors affecting cardiopulmonary function after hsPDA ligation. Preoperative assessment and intervention should be strengthened to reduce the risk of postoperative complications.

OBJECTIVE: To investigate the association between ABO blood types and gestational diabetes mellitus (GDM) risk. METHODS: A prospective birth cohort study was conducted. ABO blood types were determined using the slide method. GDM diagnosis was based on a 75-g, 2-h oral glucose tolerance test (OGTT) according to the criteria of the International Association of Diabetes and Pregnancy Study Groups. Logistic regression was applied to calculate the odds ratios ( ORs) and 95% confidence intervals ( CIs) between ABO blood types and GDM risk. RESULTS: A total of 30,740 pregnant women with a mean age of 31.81 years were enrolled in this study. The ABO blood types distribution was: type O (30.99%), type A (26.58%), type B (32.20%), and type AB (10.23%). GDM was identified in 14.44% of participants. Using blood type O as a reference, GDM risk was not significantly higher for types A ( OR = 1.05) or B ( OR = 1.04). However, women with type AB had a 19% increased risk of GDM ( OR = 1.19, 95% CI = 1.05-1.34; P < 0.05), even after adjusting for various factors. This increased risk for type AB was consistent across subgroup and sensitivity analyses. CONCLUSION The ABO blood types may influence GDM risk, with type AB associated with a higher risk. Incorporating it-either as a single risk factor or in combination with other known factors-could help identify individuals at risk for GDM before or during early pregnancy.

CD200 and its receptor CD200R constitute an endogenous inhibitory signal. The binding of CD200 and CD200R can regulate the immune response to pathogenic stimuli, which has received much attention in recent years. It has been found that CD200-CD200R is involved in the regulation of many kinds of pathological inflammation, including autoimmune diseases, cardiac cerebrovascular disease, infection and tumor. This paper reviews the protein structure, distribution, expression, biological function of CD200-CD200R and the correlation with diseases, and analyses the current status and development ideas of CD200-CD200R as drug targets. It aims to provide theoretical support for new drug research and development based on this target.

ObjectiveCoronavirus is a class of long-standing pathogens, which are enveloped single-stranded positive-sense RNA viruses. The genome all encodes 4 structural proteins: spike protein (S), nucleocapsid protein (N), membrane protein (M), and envelope protein (E). The nucleocapsid protein (NP) serves as a key structural component of coronaviruses, playing a vital function in the viral life cycle. NP acts as an RNA-binding protein, with a critical role in identifying specific sequences within the viral genome RNA, facilitating the formation of ribonucleoprotein (RNP) complexes with viral RNA to stabilize the viral genome and contribute to viral particles assembly. The NP consists of two primary structural domains, the N-terminal domain (NTD) and the C-terminal domain (CTD). The NTD is primarily responsible for RNA binding, whereas the CTD is involved in polymerization. The N protein demonstrated to trigger the host immune response and to modulate the cell cycle of infected cells by interacting with host proteins. The NP, one of the most abundant protein in coronaviruses, is essential in understanding the pathogenic mechanism of coronaviruses through its interaction with host factors, which response for determining the virus pathogenicity. HCoV-229E is a widely distributed coronavirus that typically causes mild upper respiratory tract diseases, accounting for a significant portion of common cold cases. However, its pathogenicity is notably lower compared to other coronaviruses like MERS-CoV, SARS-CoV, and SARS-CoV-2. The exact molecular mechanism behind remains unexplained, and how HCoV-229E N protein influences virus replication, host antiviral immunity, and pathogenesis need to be further explored. MethodsProximity labeling-mass spectrometry technique and bioinformatics analysis were used to screen for potential host factors interacting with the NP of human coronavirus 229E (HCoV-229E). In this study, a recombinant adenovirus Ad-V5-NP^HCoV-229E-TurboID was constructed to express the fusion protein of HCoV-229E NP and biotin ligase (TurboID). A549 cells were infected with the Ad-V5-NP^HCoV-229E-TurboID. After 30 min biotin treatment, NP interacting proteins were labeled with biotin by biotin ligase, and subsequently isolated with streptavidin cross-linked magnetic beads. The potential interacting proteins were identified using label-free proteomic mass spectrometry and further validated through immunoprecipitation and immunofluorescence assays. ResultsWe identified a total of 584 potential interacting proteins. Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis highlighted the enrichment of glycogen synthase kinase (GSK)3A and GSK3B in the glycolysis/gluconeogenesis pathway, indicating HCoV-229E NP connection to diabetes through aberrant activity. Moreover, SARS-CoV-2 infection can exacerbate hyperglycemia and metabolic dysregulation in diabetic individuals by activating the ACE2 receptor. Moreover, SARS-CoV-2 was observed to cause potentially harm to pancreatic β‑cells and leading to insulin deficiency, which not only worsens the condition of diabetic patients but also raises the possibility of new-onset diabetes in non-diabetic individuals. We demonstrated that GSK3A and GSK3B interacted with NP of HCoV-229E, suggesting that the NP may engage in various coronavirus pathogenic processes by interacting with GSK3. ConclusionThese findings suggest that proximity labeling-mass spectrometry technique is a valuable tool for identifying virus-host interaction factors, and lay the foundation for future investigations into the mechanisms underlying coronavirus replication, proliferation, and pathogenesis.

In this study, the effective substance group and molecular mechanism of Rhei Radix et Rhizoma-Persicae Semen combination (RRR-PS) in activating blood circulation and dispelling blood stasis were investigated by integrating efficacy experiments, network pharmacology and HPLC. The rat model of blood stasis syndrome was established, and the blood rheology index and coagulation four comprehensive evaluation were carried out. The results showed that compared with the model group, the whole blood viscosity, erythrocyte sedimentation rate and erythrocyte aggregation index of the rats in the RRR-PS group were significantly callback (P < 0.01). Network pharmacology found that RRR-PS combination exerted the effect of activating blood circulation and dispelling blood stasis by acting on calmodulin-1 (CALM1), nitric oxide synthase-2 (NOS2), glucocorticoid receptor (NR3C1) and other targets, regulating platelet activation, peroxisome proliferator-activated receptor (PPAR), vascular endothelial growth factor A (VEGF) and other signaling pathways, and found key components: sennoside B, (+)-catechin, emodin, physcion, rhein, aloe-emodin, chrysophanol, gallic acid. HPLC was used to explore the dissolution rate of key components. The results showed that the contents of catechin, emodin, chrysophanol and physcion were significantly increased after RRR-PS combination (P < 0.01). In summary, RRR-PS has a significant effect on promoting blood circulation and removing blood stasis, and its mechanism of action is related to promoting angiogenesis, anti-coagulation, anti-thrombosis and anti-inflammation. The efficacy is related to the change of solvent system and the large dissolution of catechin, emodin, chrysophanol and physcion after the RRR-PS combination. The results of the study can further provide a reference for the follow-up study on the active substances and mechanism of the RRR-PS combination. Animal experiments have been approved by the Experimental Animal Committee of Shaanxi University of Traditional Chinese Medicine (No. SUCMDL20210309002).

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor (TSHR) gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype–phenotype relationships for most TSHR variants associated with CH remain unexplored. We aimed to identify TSHR variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between TSHR genotypes and clinical phenotypes. Methods: In total, 367 patients with CH were recruited for TSHR variant screening using whole-exome sequencing. The effects of the variants were evaluated by in-silico programs such as SIFT and polyphen2. Furthermore, these variants were transfected into 293T cells to detect their Gs/cyclic AMP and Gq/11 signaling activity. Results: Among the 367 patients with CH, 17 TSHR variants, including three novel variants, were identified in 45 patients, and 18 patients carried biallelic TSHR variants. In vitro experiments showed that 10 variants were associated with Gs/cyclic AMP and Gq/11 signaling pathway impairment to varying degrees. Patients with TSHR biallelic variants had lower serum TSH levels and higher free triiodothyronine and thyroxine levels at diagnosis than those with DUOX2 biallelic variants. Conclusions We found a high frequency of TSHR variants in Chinese patients with CH (12.3%), and 4.9% of cases were caused by TSHR biallelic variants. Ten variants were identified as loss-of-function variants. The data suggest that the clinical phenotype of CH patients caused by TSHR biallelic variants is relatively mild. Our study expands the TSHR variant spectrum and provides further evidence for the elucidation of the genetic etiology of CH.
