ObjectiveTo establish a geographical origin identification model for Foeniculi Fructus from Haiyuan, providing a new technical reference for the protection of Haiyuan's geo-authentic medicinal materials and its designation as a national geographical indication agricultural product. MethodsSamples of Foeniculi Fructus were collected from eight producing areas, including Minqin (Gansu), Bozhou (Anhui), Qingdao (Shandong), Dezhou (Shandong), Urumqi (Xinjiang), Nujiang (Yunnan), Gutuo (Inner Mongolia), and Haiyuan (Ningxia). Gas chromatography-ion mobility spectrometry (GC-IMS) was used to detect the volatile organic compounds (VOCs) in samples from these geographic origins. VOCs were qualitatively analyzed through dual matching with the National Institute of Standards and Technology (NIST) mass spectral database and the IMS drift time database. Using the Reporter module and Gallery Plot visualization tools within the LAV analytical platform, VOC fingerprint profiles characterizing geographic origins were constructed. A non-targeted analytical strategy was adopted, and 97 VOCs detected via GC-IMS were subjected to principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) based on their differential distribution patterns to construct an origin identification model for Foeniculi Fructus from Haiyuan region. Key discriminative markers were screened using variable importance in projection (VIP) values greater than 1. ResultsA total of 97 VOCs were identified, including alcohols, aldehydes, ketones, esters, organic acids, terpenoids, ethers, alkenes, and benzenes. The PLS-DA model, based on VOCs data obtained by GC-IMS, effectively distinguished Foeniculi Fructus in Haiyuan region from those of other origins. During cross-validation, the model achieved a prediction parameter (Q2) of 0.976 and a goodness-of-fit parameter (R2) of 0.936, with no overfitting observed in permutation testing. Twelve key flavor markers with VIP > 1 were identified as characteristic indicators of Haiyuan origin. ConclusionA stable and highly predictive origin identification model for Foeniculi Fructus from Haiyuan was successfully established using GC-IMS technology, PLS-DA, and VIP-based marker screening. This model provides a novel technical strategy for accurately distinguishing Foeniculi Fructus in Haiyuan region from other regional varieties and offers new technical support for its protection as a geo-authentic medicinal material and a nationally designated geographical indication agricultural product in China.

Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules, such as limonene, linalool, linalool acetate, geraniol, and citronellol. These chemicals have been extensively studied and shown to have a variety of functions, including reducing anxiety, relieving depression, promoting sleep, and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled, they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier, thereby exerting effects on the central nervous system. Currently, the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However, the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances, including plant extracts and natural small molecule compounds, in antibacterial and antiviral fields and the regulation of nervous system activity. As a result, a deeper understanding of aromatherapy was achieved. At the same time, the potential of these aromatic substances for drug development was thoroughly explored, providing important references and insights for possible future drug research and application.

Myocardial infarction is one of the major diseases that seriously threaten human health. In the clinical treatment of myocardial infarction, there are unpredictable complications, and most patients will suffer a severe cardiac function decline due to excessive loss of myocardia and formation of scar tissue, eventually progressing to heart failure or even death. With rapid development of biological materials, they as an important part of tissue repair and regeneration research, have become a hot spot in the research and development of cardiovascular repair materials. Among them, decellularized extracellular matrix (dECM) materials, a class of natural materials with good histocompatibility, low immunogenicity, and suitable cell growth and metabolism characteristics, have been applied in clinical or preclinical cardiovascular tissue engineering or regenerative medicine. In this review, the application progress of dECM materials in tissue engineering, including the dECM preparation of 3D printed bioink, electrospinning, matrix hydrogel, and myocardial patch, in myocardial infarction treatment was summarized, and prospects and current challenges in the treatment of myocardial infarction were discussed.

Objective:To investigate the clinical value of ultrasound-guided thoracic paravertebral block (TPVB) combined with bronchial blocker (BB) placement in thoracoscopic surgery.Methods:A randomized controlled study was conducted involving 60 patients scheduled for thoracoscopic surgery at The First Affiliated Hospital of Xiamen University from November to December 2023. These patients were classified as American Society of Anesthesiologists (ASA) I-II. They were divided into an observation group (BB placement) and a control group (double-lumen bronchial blocker placement) using the random number table method, with 30 patients in each group. Preoperatively, TPVB was performed under ultrasound guidance. After the induction of general anesthesia, a single-lumen tracheal tube was inserted, followed by the placement of a BB in the observation group, while a corresponding type of double-lumen bronchial tube was inserted in the control group. A fiberoptic bronchoscope was used for positioning and fixation in both groups, and anesthesia was maintained with intravenous anesthesia. The following parameters were assessed in each group: positioning time for intubation; number of cases with tube displacement; number of cases of postoperative pharyngeal pain; hemodynamic parameters [mean arterial pressure (MAP) and heart rate (HR)] before and after intubation; and blood gas analysis [partial pressure of oxygen (PaO 2) and carbon dioxide (PaCO 2)]. Additionally, the surgical field exposure score and the dosages of propofol and remifentanil administered during surgery were recorded. Levels of inflammatory markers [interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF) -α, and TNF-β] and Visual Analog Scale scores for pain at rest and during cough, recorded at 2, 4, 8, 10, 12, and 24 hours postoperatively were compared between the two groups. Results:The total amounts of propofol [(569.7 ± 29.2) mg] and remifentanil [(289.3 ± 46.3) μg] in the observation group were significantly lower than those in the control group [(612.6 ± 28.7) mg, (361.7 ± 40.6) μg, t = 5.74, 6.44, both P = 0.001]. The recovery time in the observation group [(31.8 ± 11.4) minutes] was significantly shorter than that in the control group [(37.5 ± 10.1) minutes, t = 2.10, P = 0.040]. There was no significant difference in positioning time for intubation between observation and control groups [(67 ± 13) seconds vs. (80 ± 36) seconds, t = 1.86, P = 0.068). There was no significant difference in percentage of cases who underwent tube displacement after intubation between observation and control group [23.3% (7/30) vs. 16.7% (5/30), χ2 = 0.58, P = 0.445]. The incidence of postoperative pharyngeal pain in the observation group was significantly lower than that in the control group [10.0% (3/30) vs. 33.3% (10/30), χ2 = 5.02, P = 0.025). There were no statistically significant differences between the two groups in terms of number of cases with tube displacement, hemodynamic parameters, blood gas analysis, inflammatory markers, surgical field exposure, and postoperative Visual Analog Scale scores between the two groups (all P > 0.05). Conclusion:Ultrasound-guided TPVB combined with BB placement during thoracoscopic surgery can reduce airway injury compared with the use of a double-lumen bronchial tube. It provides adequate sedation and analgesia during the procedure, facilitates rapid awakening, promotes early recovery of spontaneous breathing, and has fewer adverse reactions, making it worthy of clinical promotion.
