The identification of the components absorbed in serum of platycosides in total saponins fraction of Platycodonis Radix is great significance, but there are still great challenges. In this study, 8 types of 44 primordial components from Platycodon saponins were firstly identified using the ultra-performance liquid chromatography-linear ion trap electrostatic field orbitrap high resolution mass spectrometry (UPLC-LTQ-Orbitrap-MS) equipped with the software of Compound Discoverer 3.2 and Trace finder 2.1. Then, the platycosides and their deglycosylated metabolites were used as the template molecules to construct the intestinal microbiota mediated method to identify the primary components and the prototypes in serum. As results, 57 components originating from 44 prototypes of platycosides were identified from drug-containing plasma. Those compounds consist of 12 prototypes of platycosides and 45 metabolites, while the prototypes in serum are also deglycosylated metabolites of other platycosides. The results showed that the intestinal microbiota mediated method could be applied to identify the metabolites of platycosides in total saponins fraction of Platycodonis Radix; and reveal the potential existing forms of prototypes of platycosides in plasma; In addition, it could clearly illustrate the one to many and many to one network of the prototypes and metabolites of platycosides. All animal protocols were approved by the Animal Ethics Committee of Jiangxi University of Traditional Chinese Medicine (No.JZLLSC-202100322).

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective:To validate the morphological changes of the parieto-occipital sulcus on the transcalvarial axial plane between 20 and 32 weeks of gestation, simplify grade for assessing fetal parieto-occipital sulcus development, and confirm its clinical feasibility.Methods:This was a cross-sectional study analysis that included 550 cases of normal singleton fetuses between 20 and 32 weeks of gestation, who underwent routine ultrasound examinations at Shenzhen Maternity and Child Healthcare Hospital from September 2019 to June 2022. The morphological changes of the bilateral parieto-occipital sulci on the transcalvarial axial plane were observed. The development of the parieto-occipital sulcus was classified into 6 grades based on the developmental features of angulation, progressive closure, and curvilinear growth: straight or shallow arcuate (Grade 0), shallow and wide V-shaped (Grade 1), deep and narrow V-shaped (Grade 2), Y-shaped (Grade 3), I-shaped (Grade 4), and curvilinear (Grade 5). The gestational age at examination and pregnancy outcomes were recorded. The distribution of gestational weeks for fetuses with different grades of parieto-occipital sulci on the left and right sides was analyzed. The symmetry between bilateral parieto-occipital sulcus gradings within individuals, as well as the inter-observer and intra-observer reliability were assessed using the Weighted Kappa coefficient. The gender differences in asymmetry of parieto-occipital sulci grades between the left and right sides was analyzed. Moreover, a model for predicting the grade of the parieto-occipital sulcus based on gestational week was established.Results:Grade for the left parieto-occipital sulcus was obtained for 549 fetuses, while grade for the right was obtained for 550 fetuses. From 20 to 32 weeks of gestation, the morphology of the fetal parieto-occipital sulcus was divided into Grade 0-5, progressing from low to high with gestational development. Grade 0 showed that the sulcus was not visible or only had a slight arcuate indentation, occurring at 20-22 weeks; Grade 1 presented as a shallow and wide "V" shape with an obtuse angle at the top, appearing from 20 to 27 weeks; Grade 2 was a deep and narrow "V" shape with an acute angle at the top, appearing from 24 to 29 weeks; Grade 3 appeared as a "Y" shape with the top part partially closed and the bottom still open, occurring between 26 to 30 weeks; Grade 4 was a fully closed "I" shape, appearing at 29-32 weeks; Grade 5 presented as a curved shape, indicating the parieto-occipital sulcus was approaching maturity, appearing from 31 to 32 weeks. There was no statistically significant difference in the distribution of gestational weeks for bilateral parieto-occipital sulcus developmental grade ( P>0.05). Bilateral parieto-occipital sulcus grade could be assessed in 549 fetuses, of which 43 cases (7.83%) exhibited grade asymmetry with a one-grade difference between sides; such asymmetry showed no significant difference between male and female genders ( P=0.647). The weighted kappa coefficient analysis results indicated a strong consistency in the development of the parieto-occipital sulci on both sides within individuals, generally demonstrating symmetrical development ( P<0.001). The intra-observer and inter-observer weighted kappa coefficients were 0.92 and 0.75, respectively, with good consistency. Conclusions:Prenatal ultrasound via the transcalvarial axial plane enables a preliminary and rapid assessment of the development of bilateral parieto-occipital sulci, facilitating early evaluation of fetal cortical maturation.

Objective:To study the stability and morphological changes of the convexity sulci in normal fetuses between 20 and 32 weeks, and to explore the simplified grade for evaluating the convexity sulci development and analyzing its clinical significance.Methods:This study was a cross-sectional analysis. A total of 551 cases of normal singleton pregnancies between 20 and 32 weeks of gestation were retrospectively collected, who underwent routine ultrasound examinations at Shenzhen Maternity and Child Healthcare Hospital from September 2019 to June 2022. The display of the far-field convexity sulci on the transcalvarial axial plane was observed as 0 for not displayed and 1 for displayed.Further, based on the morphology and number of convexity sulci, they were classified into five grades: no sulcus displayed (grade 0), one sulcus (grade 1), two sulci (grade 2), three sulci (grade 3), and four or more sulci (grade 4). The gestational age at examination and pregnancy outcomes were recorded. The distribution characteristics of gestational weeks for each grade of the convexity sulci were analyzed, and the gestational week distribution of the left and right convexity sulci was compared to analyze bilateral symmetry. The Weighted Kappa coefficient was used to analyze inter-observer and intra-observer consistency, and curve regression analysis was employed to establish a model for predicting grade based on gestational weeks.Results:Before 25 weeks of gestation, the convexity of the fetal cranial vertex was completely smooth.The central sulcus consistently appeared after 26 weeks, while the superior frontal sulcus, intraparietal sulcus, postcentral sulcus, and precentral sulcus consistently appeared between 28 and 31 weeks. Among these, the superior frontal sulcus had a lower display rate before 29 weeks. By 32 weeks, all convexity sulci of the cranial vertex should be visible. Three hundred and eleven fetuses were graded for the left, and 240 fetuses were graded for the right. The developmental grade of the convexity sulci increased from Grade 0 to Grade 4 as the gestational age progressed. Grade 0 appeared between 20-26 weeks, grade 1 between 25-28 weeks, grade 2 between 26-28 weeks, grade 3 between 27-30 weeks, and grade 4 between 27-32 weeks. The distribution of grade did not differ significantly between the left and right sides of grade 0, 1, 3 and 4 (all P>0.05), while there was a significant difference in the distribution of gestational age between the convexity sulci of grade 2 ( P<0.05). The Weighted Kappa coefficients for intra-observer and inter-observer consistency were 0.94 and 0.86, respectively, indicating strong consistency. Conclusions:The simplified grade for assessing the development of convexity sulci in normal fetuses on the transcalvarial axial plane via prenatal ultrasound can provide a preliminary evaluation of the maturation of convexity sulci in fetuses between 20 and 32 weeks of gestation.

Objective:To analyze the clinical characteristics and influencing factors of vascular involvement in Beh?et′s Disease (BD) to improve and provideunderstanding of insights for clinicians to better understand this condition.Methods:Clinical data from 220 BD patients admitted to the First Affiliated Hospital of Guangxi Medical University from January 2012 to May 2022 were collected. Clinical manifestations and laboratory findings were compared between BD patients with and without vascular involvement, as well as between those with improved conditions and those with progressive conditions. Binary logistic regression was used to analyze the influencing factors.Results:①The average age of the 220 BD patients was 36.5±15.3 years. Among them, 23 patients (10.5%) had vascular involvement, including 20 males (87.0%).②Compared to BD patients without vascular involvement, those with vascular involvement had significantly higher rates of smoking [6.1%(12/197) vs.34.8%(8/23), χ2=17.19, P<0.001], cardiac involvement [1.5%(3/197) vs. 13.0%(9/23), χ2=6.42, P=0.011], and elevated C-reactive protein(CRP) levels (78.3% vs. 56.3%, χ2=4.08, P=0.043).③ Among BD patients with vascular involvement, 11 cases (47.8%) had venous lesions, and 20 cases (87.0%) had arterial lesions, with 8 cases (34.8%) having both venous and arterial involvement. The most common type of vascular involvement was arterial dilatation (11 cases), mainly aneurysms (10 cases), and deep venous thrombosis of the lower extremities (7 cases).④The 23 BD patients with vascular involvement were followed up for an average of 18.3 months. Among them, 16 patients (69.6%) showed stable improvement, while 7 patients (30.4%) experienced disease progression, including 4 deaths (1 male and 3 females). A total of 91.3% (21/23) of the patients received glucocorticoid therapy. Immunosuppressive therapy was administered to 82.6% (19/23) of the patients, with 65.2% (10/23) receiving with cyclophosphamide and 43.5% receiving with thalidomide. Additionally, 13% (3/23) of the patients were treated with cyclosporine and methotrexate, respectively, and 8.7% (2/23) were treated with received mycophenolate mofetil. Anticoagulant therapy was given to 21.7% (5/23) of the patients, using either warfarin or low molecular weight heparin. Biologic therapy was administered to 17.4% (4/23) of the patients, and surgical intervention was performed in 43.5% (10/23) of the patients. ⑤Binary logistic regression analysis identified male gender [ OR(95% CI)=5.70(1.60, 20.90), P=0.009] as an indepe-ndent risk factor for vascular involvement in BD. Conclusion:The incidence of vascular involvement in BD is 10.5%, with a higher prevalence in males. Arterial involvement is more common than venous involvement, with arterial aneurysms being the most common manifestation. Clinicians should pay attention to CRP and total cholesterol levels in BD patients.

This paper aimed to explore the antidepressant effect of the essential oil from Schizonepeta tenuifolia Briq.(EOST) on the treatment of depression and its mechanism by using a combination of network pharmacology and the mouse model of lipopolysaccharide(LPS)-induced depression. The chemical components in EOST were identified using gas chromatography-mass spectrometer(GC-MS), and 12 active components were selected as the study objects. The targets related to EOST were obtained by Traditional Chinese Medicines Systems Pharmacology(TCMSP) and SwissTargetPrediction database. The targets related to depression were screened out through GeneCards, Therapeutic Target Database(TTD), and Online Mendelian Inheritance in Man(OMIM) database. The Venny 2.1 was applied to screen out the common targets of EOST and depression. The targets were imported into Cytoscape 3.7.2 to generate "drug-active component-diease-target" network diagram. The protein-protein interaction(PPI) network was constructed using STRING 11.5 database and Cytoscape 3.7.2, and the core targets were screened out. DAVID 6.8 database was used for Gene Ontology(GO) func-tional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis, and subsequently the enrichment results were visualized through the bioinformatics platform. The mouse model of depression was induced by intraperitoneally injecting with LPS in mice. Before modeling, mice were administrated orally with EOST. The antidepressant effect of EOST was evalua-ted by tail suspension test(TST), forced swimming test(FST), and novelty suppressed feeding test(NSFT) after modeling. The content of interleukin(IL)-1β was determined by enzyme-linked immunosorbent assay(ELISA), and the protein expression levels of IL-1β and pro IL-1β in the hippocampus were determined by Western blot. There were 12 main components and 179 targets in EOAT, of which, 116 targets were related to depression, mainly involved in neuroactive ligand-receptor interaction, calcium signaling pathway, and cyclic adenosine monophosphate(cAMP) signaling pathway. Biological processes such as synaptic signal transduction, G-protein coupled receptor signaling pathway, and chemical synaptic transmission were involved. Molecular functions such as neurotransmitter receptor activity, RNA polymerase Ⅱ transcription factor activity, and heme binding were involved. In mice experiments, the results showed that EOST at 100 mg·kg~(-1) and 50 mg·kg~(-1) significantly shortened the immobility time in TST and FST as well as the feeding latency in NSFT compared with the model group, decreased the levels of serum IL-1β and NO, and reduced the protein expression levels of IL-1β and pro IL-1β in the hippocampus. In conclusion, EOST shows a good antidepressant effect in a multi-component, multi-target, and multi-pathway manner. The mechanism may be attributed to the fact that EOST can down-regulate the protein expression levels of IL-1β and pro IL-1β, decrease the release of inflammatory factors, and reduce neuroinflammation response.

Pyroptosis is a programmed cell death initiated by the activation of caspases, which is involved in the development and progression of several cardiovascular diseases. The gasdermins, a protein family, are key executive proteins in the development of pyroptosis, which increase cell membrane permeability, mediate the release of inflammatory factors, and aggravate the inflammatory injury. Traditional Chinese medicine(TCM)has shown unique therapeutic advantages in cardiovascular diseases with multi-component and multi-target characteristics. Currently, the effective prevention and treatment of cardiovascular diseases based on the theory of pyroptosis become a new research hotspot in this field. Based on the theories of TCM and modern medicine, this study summarized the role of pyroptosis in cardiovascular diseases such as atherosclerosis, myocardial infarction, diabetic cardiomyopathy, hypertension, and myocarditis. The role of TCM, including active monomers, crude extracts, and compound preparations, in cardiovascular protection through the regulation of pyroptosis was also summarized, providing a theoretical basis for the clinical prevention and treatment of cardiovascular diseases by TCM.

The plateau environment is characterized by low oxygen, low air pressure, low temperature, and strong ultraviolet rays, etc. Chronic obstructive pulmonary disease (COPD) is a preventable and treatable chronic lung disease. High altitude environment increases COPD prevalence, clinical manifestation and mortality. The therapeutic window of theophylline drugs for COPD is narrow, and the high altitude environment has an influence on the pharmacokinetics of the drugs. This review summarizes the differences in the prevalence, mortality, clinical manifestation and clinical symptoms of COPD in the plateau and plain, providing a basis for identifying the risk factors of COPD in the plateau areas. The effects of plateau hypoxic environment on the pharmacokinetics of COPD drugs were also discussed. It can provide a rationale for more effective prevention and treatment of COPD at high altitude.
