ObjectiveTo investigate the effects of Sanjie Quban prescription （SJQB）-containing serum on the proliferation， apoptosis， migration， and invasion of human keloid fibroblasts （KFs） and to elucidate its underlying mechanism， with a focus on the aryl hydrocarbon receptor （AhR）/cytochrome P450 family 1 subfamily A member 1 （CYP1A1） signaling pathway. MethodsPrimary human KFs were cultured in vitro and assigned to the following groups： control （KFs+blank serum）， asiaticoside （KFs+asiaticoside-containing serum）， SJQB （KFs+SJQB-containing serum）， AhR agonist （KFs+β-naphthoflavone）， AhR inhibitor （KFs+CH223191）， and AhR inhibitor+SJQB （KFs+CH223191+SJQB-containing serum）. The optimal intervention concentrations were determined through the cell counting kit-8 （CCK-8） assay. Cell proliferation， apoptosis， migration， and invasion were evaluated by the EdU assay， flow cytometry， wound healing assay， and Transwell assay， respectively. The expression of transforming growth factor-β₁ （TGF-β₁） and α-smooth muscle actin （α-SMA） was visualized by immunofluorescence. The mRNA and protein levels of AhR， CYP1A1， TGF-β₁， and α-SMA were measured by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. ResultsCompared with the control group， the SJQB， asiaticoside， and AhR agonist groups demonstrated inhibited cell proliferation， migration， and invasion， along with an increased apoptosis rate （P<0.01）. The AhR inhibitor group showed enhanced proliferation， migration， and invasion together with a reduced apoptosis rate in comparison with the AhR agonist group （P<0.01）. The AhR inhibitor+SJQB group exhibited increased proliferation， migration， and invasion as well as decreased apoptosis compared with the SJQB group （P<0.05， P<0.01）. At the molecular level， compared with the control group， the SJQB， asiaticoside， and AhR agonist groups presented upregulated protein and mRNA levels of AhR and CYP1A1 （P<0.05， P<0.01）， while the SJQB and AhR agonist groups showed downregulated TGF-β₁ and α-SMA expression at both protein and mRNA levels （P<0.05， P<0.01）， and the asiaticoside group displayed decreased protein level of TGF-β₁ and mRNA level of α-SMA （P<0.05， P<0.01）. Compared with both the AhR agonist and control groups， the AhR inhibitor group exhibited decreased AhR and CYP1A1 expression but increased TGF-β₁ and α-SMA expression at protein and mRNA levels （P<0.01）. In comparison with the SJQB group， the AhR inhibitor+SJQB group demonstrated reduced AhR and CYP1A1 expression （P<0.01） and elevated TGF-β₁ and α-SMA expression （P<0.05， P<0.01） at both protein and mRNA levels. ConclusionSJQB may activate the AhR/CYP1A1 signaling pathway to downregulate TGF-β₁ and α-SMA expression， thereby suppressing the proliferation， migration， and invasion and inducing the apoptosis of KFs.

OBJECTIVE To investigate the efficacy and safety of ropivacaine in transversus thoracis muscle plane block （TTMP） combined with pecto-intercostal fascial plane block （PIFB） for postoperative analgesia in median sternotomy.METHODS A total of 70 patients who underwent median sternotomy at the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture， from December 2025 to April 2026 were enrolled and randomly divided into the TTMP group （group T， n ＝35） and the TTMP combined with PIFB group （group TP， n ＝35）. Both groups received 40 mL of 0.3% ropivacaine under ultrasound guidance. group TP received bilateral TTMP combined with PIFB， while group T received bilateral TTMP alone. The total consumption of sufentanil within 48 hours postoperatively， analgesic indicators （intraoperative total sufentanil consumption， time to first patient-controlled analgesia pump press， number of effective analgesia pump presses）， recovery indicators （postoperative extubation time， length of ICU stay， time to first flatus， time to postoperative drainage tube removal， total length of hospital stay）， circulatory indicators （heart rate and mean arterial pressure at different time points）， postoperative pain scores [Visual Analog Scale （VAS） scores at rest and during movement at different time points]， and the incidence of adverse reactions （nausea and vomiting， CO 2 retention， delirium， respiratory tract infection） were compared between the two groups.RESULTS One patient in each group withdrew from the study. The total consumption of sufentanil within 48 hours postoperatively， all analgesic indicators， all recovery indicators， and VAS scores at rest and during movement in group TP were significantly better than those in group T （ P ＜0.05）. There were no statistically significant differences in circulatory indicators or the incidence of most adverse reactions between the two groups （ P ＞0.05）， but the incidence of postoperative CO 2 retention in group TP was significantly lower than that in group T （ P ＜0.05）.CONCLUSIONS Compared with TTMP alone， ropivacaine in TTMP combined with PIFB provides effective analgesia， promotes early recovery， and has good safety in patients undergoing median sternotomy.

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.

Hepatolenticular degeneration， also known as Wilson disease （WD）， is a hereditary disease caused by mutations in the ATP7B gene， leading to copper metabolism disorders. Gene mutations result in impaired synthesis of copper-binding protein， and abnormal excretion of copper through bile leads to pathological deposition of copper in various organs， ultimately causing multi-organ damage. The insidious onset and low specificity of symptoms make it difficult to diagnose this disease. On the basis of existing studies and the theory of latent toxin， this paper proposes that latent toxin in kidney collaterals is the main pathogenesis of renal injury in WD. It is pointed out that health Qi deficiency and latent pathogen are the premises for the occurrence of this disease， and the transformation of latent pathogen into toxin is the ley pathological process. Toxin damaging kidney collaterals is the ultimate result. According to the pathogenesis， this paper proposes the treatment principle of reinforcing healthy Qi and resolving toxin and treatment based on syndrome differentiation. This review provides new ideas for the diagnosis and treatment of renal injury in WD with traditional Chinese medicine.

ObjectiveTo observe the clinical efficacy of Gandouling decoction combined with neuromuscular electrical stimulation （NMES） in the treatment of dysphagia in Wilson disease （WD） with combined phlegm and stasis. MethodsA total of 80 WD patients with dysphagia due to combined phlegm and stasis treated in the Department of Encephalopathy， the First Affiliated Hospital of Anhui University of Chinese Medicine were randomized into a control group and an observation group， with 40 patients in each group. In addition， 40 healthy volunteers were recruited as the normal group. The control group was treated with basic copper drainage combined with NMES. The observation group was treated with Gandouling Decoction on the basis of the therapy in the control group. Each course of treatment lasted for 8 days， and the patients were treated for a total of 4 courses. All subjects underwent video fluoroscopic swallowing study （VFSS） before and after treatment. During the examination， contrast agents with 4 different characters were used for the swallowing action， and the passing time was recorded. The TCM syndrome score， water swallow test score， standard swallowing assessment （SSA） score， and 24-h urinary copper level before and after treatment were analyzed. ResultsWhen performing VFSS， the passing time of contrast agents of different characters in the oral stage was longer in the WD group than in the normal group （P<0.01）， while it had no significant difference in the pharyngeal stage. After treatment， the passing time in the oral stage shortened in the control and observation groups （P<0.01）， and the observation group outperformed the control group （P<0.01）. After treatment， both the control and observation groups showed declines in TCM syndrome score and SSA score （P<0.01） and an increase in water swallow test score （P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.01）. In addition， the treatment in the control and observation groups elevated the 24-h urinary copper level （P<0.01）， and the elevation in the observation group was more obvious than that in the control group （P<0.01）. Neither group showed obvious adverse reaction. ConclusionGandouling decoction combined with NMES can significantly ameliorate dysphagia in WD patients with the syndrome of combined phlegm and stasis regarding the TCM syndrome score， water swallow test score， and SSA score， demonstrating definite clinical efficacy and high safety.

ObjectiveTo investigate the effects of different fermentation methods and times on the fungal flora and chemical composition of Aurantii Fructus， in order to obtain the optimal fermentation conditions and flora structure， and to ensure the stability and controllability of the fermented varieties. MethodsScanning electron microscopy was used to observe and analyze the colony characteristics on the surface of Aurantii Fructus under different fermentation conditions. Internal transcribed spacer 2（ITS2） high-throughput sequencing， combined with fungal community diversity analysis and fungal community structure analysis， were used to obtain the fungal flora microbial categories of Aurantii Fructus under the conditions of traditional pressure-shelf fermentation and non-pressure-shelf natural fermentation for 7， 14， 21 d（numbered Y1-Y3 for the former， and numbered F1-F3 for the latter）， respectively. At the same time， the chemical components in the fermentation process were detected by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）， combined with principal component analysis（PCA）， partial least squares-discriminant analysis（PLS-DA） and compound retention time， parent ions， characteristic fragment ions and other information， the differential compounds between the different fermentation samples were screened and identified. ResultsThe analysis of fungal community diversity showed that the dominant flora did not change at different fermentation time points in the traditional pressure-shelf fermentation method， while in the non-pressure-shelf natural fermentation method， there was a significant difference with the fermentation process， and at the genus level， the dominant genus of samples Y1， Y2， Y3 and F2 was Aspergillus， while the dominant genera of samples F1 and F3 were both Rhizopus. This indicated that the microbial growth environment provided by the traditional fermentation method was more stable， and the microbial community structure was more stable， which was more conducive to the stable and controllable fermentation process and fermented products. A total of 155 compounds were identified by compositional analysis， including 70 flavonoids， 38 coumarins， 10 alkaloids， 34 organic acids and 3 other compounds. After fermentation， two new components of ribalinine and pranferin were produced. Different fermentation conditions also brought about differences in chemical composition， multivariate statistical analysis obtained 26 differential compounds under two different fermentation methods， mainly including flavonoids， organic acids and coumarins. Comprehensively， the microbial community structure of samples fermented by the traditional pressure-shelf method of Aurantii Fructus for 14 d was stable， the species richness was high and the overall content of differential compounds was high， which was the optimal processing condition. ConclusionCompared with non-pressure-shelf natural fermentation， the traditional method has obvious advantages in terms of the stability of the microbial community structure and the content of chemical compounds， and the optimal condition is 14 days of fermentation. This study is helpful to promote the quality stability and fermentation bioavailability of fermented products of Aurantii Fructus， as well as to provide an experimental basis for the further improvement of the quality control methods of this variety.
