ObjectiveTo explore the changes in color， odor and chemical components during wine-processing of Chuanxiong Rhizoma（CR）， identify differential markers， and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis（PLS-DA）， principal component analysis（PCA）， discriminant factor analysis（DFA） and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models， and differential components were screened out based on variable importance in the projection（VIP） value1. Then， high performance liquid chromatography（HPLC） was employed to detect the content changes of four components（ferulic acid， senkyunolide I， senkyunolide A and ligustilide） during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L^*（brightness value）， a^*（red-green value） and b^*（yellow-blue value）. Based on chromaticity differences， the color reference ranges were established for moderately processed CR， including L^* of 46.75-48.24， a^* of 5.37-6.07 and b^* of 20.32-21.70. In odor analysis， DFA revealed significant differences among processing stages， and 11 odor markers were identified， with four differential markers（4-hydroxy-3-butylphthalide， isopropyl butyrate， L-limonene and 1-methoxyhexane） based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection， with discrimination accuracy rates of 92.4% and 93.272% for color and odor， respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages， and four differential components were screened out， providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

Objective To screen antidepressant-active compounds from Polygonati Rhizoma and explore their effects and possible mechanisms against depression induced by simulated weightlessness.Methods A systems pharmacology approach was used to screen potential antidepressant-active compounds and their targets from Polygonati Rhizoma.The hindlimb unloading(HLU)rat model was employed for the study.Twenty-four healthy male Sprague-Dawley rats were randomly divided into three groups:control group(administered 0.5%carboxymethylcellulose by gavage),HLU group(hindlimb unloading),and HLU+treatment group(hindlimb unloading+active compound gavage),with 8 rats in each group.After 28 days of hindlimb unloading,depressive-like behaviors in rats were evaluated using the forced swimming test and tail suspension test.Hippocampal morphology was examined with H&E staining,and GO and KEGG enrichment analyses were conducted on the targets of active compounds.Results A total of 38 active compounds were screened from Polygonati Rhizoma,among which apigenin had an oral bioavailability of 23.06%and a drug-likeness score of 0.21.Compound-target network analysis indicated that apigenin had the highest degree and betweenness centrality values,suggesting it might be the key active component with antidepressant potential in Polygonati Rhizoma.In the forced swimming and tail suspension tests,rats in the HLU group showed a significant increase in immobility time compared to the control group,indicating successful establishment of the depression model.However,compared to the HLU group,rats in the HLU plus apigenin group exhibited significantly reduced immobility time.The H&E staining results of hippocampal tissue showed a significant reduction in the number of hippocampal neurons,along with numerous shrunken neurons and small vacuoles in nerve fibers in the HLU group.In contrast,the treatment group exhibited an increased number of hippocampal neurons,with improved cellular morphology.Target enrichment analysis indicated that apigenin targets were mainly involved in the regulation of apoptosis and cancer-related signaling pathways.Conclusion Apigenin significantly improved depressive-like behaviors in rats subjected to hindlimb unloading,and it has a protective effect on hippocampal tissue.It may provide a new natural active compound for the treatment of depression caused by spaceflight-induced weightlessness.

Objective To investigate the effect of hyperglycemia activated CCAAT enhancer binding protein β(C/EBPβ)promoting the expression of thyroid hormone nuclear receptor α1(THα1)on diabetic cardiomyopathy(DCM).Methods Twenty healthy male Wistar rats were randomly divided into diabetes mellitus(DM,n=10)group and DCM(n=10)group.Cardiomyocyte were divided into four groups:DM-cell,glucose intervention(Glu),knockdown C/EBPβ group(cardiomyocyte were transfected with plasmids targeting knockdown C/EBPβ)and si-NC group(cardiomyocyte were transfected with nagetive control sequence of plasmids).HE and Masson staining was performed to detect myocardial injury and collagen deposition.Echocardiography was used to evaluate left ventricular function.The mRNA and protein expression of C/EBP β and THα1 was detected using RT-qPCR,Western blot and immunofluorescence staining in myocardial cells.Apoptosis was analyzed using flow cytometric.Contraction frequency was counted by microscopy.Results Compared to DM group,count of fibroblasts,collagen volume fraction,end-systolic dimension of left ventricular,and the mRNA and protein expression of C/EBPβ and THα1 as well as fluorescence intensity increased(P<0.05);left ventricular ejection fraction and left ventricular fractional shortening(LVFS)decreased in DCM group(P<0.05).The mRNA and protein expression of C/EBPβ and THα1 were higher in the Glu group than in DM-cell group(P<0.05).The percentage of apoptosis,the mRNA and protein expression of THα1 of myocardial cells were lower in the si-C/EBPβ group than in the si-NC group(P<0.05),and LVFS was higher in the si-NC group(P<0.05).Conclusions High glucose regulates C/EBPβ expression,which in turn drives THα1 expression in myocardial tissue,leading to adverse effects on myocardial tissue.Conversely,silencing C/EBPβ downregulates THα1 expression,and exerts a protective effect on cardiomyocytes.

[Objective] To compare next generation sequencing (NGS) library construction technology between probe hybridization capture and amplicon methods, and analyze the influencing factors of HLA genotyping resolution level and its prospects in clinical applications. [Methods] A total of 207 clinical samples with known typing results and samples from the proficiency testing plan were selected. The conformity rate of HLA genotyping results, allele coverage and typing data analysis indicators were confirmed, and the effects of two library construction methods on the level of HLA genotyping discrimination were compared. [Results] The concordance rate of 207 samples with the feedback results of PT or prior well-characterized HLA genotypes was 100%. Among them, 91 samples were captured using hybridization probe capture method. Compared with the original amplicon method, the hybridization probe capture method can distinguish the alleles of DRB1 and DPB1 that cannot be determined in 13 samples. The allelic imbalance of DRB1, DPA1, and DQB1 loci in 6 samples was resolved. Three samples were found to have missed detection of alleles at the DQA1 and DQB1 loci. [Conclusion] The performance indicators of hybridization probe capture and amplicon performance confirmation meet the requirements of clinical detection of HLA genotyping, which provides an experimental method and basis for clinical application.

Objective:To observe the clinical effect of comprehensive reconstruction of grades Ⅰ-Ⅱ thumb and finger defects with hallux osteo-onychocutaneous flaps of great toe.Methods:This is a retrospective study. From June 2020 to December 2023, comprehensive reconstruction surgery for Grade Ⅰ-Ⅱ digital defect were performed with hallux osteo-onychocutaneous flaps of great toe for 3 thumbs and 7 fingers in 9 patients in the Department of Hand and Microsurgery of Baoji Third Hospital. Causes of digital injury were: 4 of machine crush, 3 of electric saw cut, 1 of door crush, and 1 of electrical burn. There were 6 grade I digital defects (beyond the nail root) and 4 grade Ⅱ defects (last segment of digit). The defects of the digits were reconstructed by taking references of the shape and structure of the contralateral normal thumbs and fingers. Then the hallux osteo-onychocutaneous flaps of great toe were designed and harvested accordingly from the left and right great toes. Donor sites were covered by skin grafting or local dressing change. One patient was treated in emergency surgery, 6 in sub-emergency surgery and 2 in elective surgery. Integrated perioperative patient management was provided to all of the patients. Postoperative follow-ups were conducted through the visit of outpatient clinic, telephone calls or WeChat interviews. Flap survival, appearance and sensation recovery were evaluated according to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association.Results:Vascular insufficiency of 1 digit occurred in surgery, and relieved by local treatment with lidocaine and warm saline. All 10 digits successfully survived, and all donor sites healed spontaneously. The postoperative follow-up period was 10 to 30 months, with an average of 18 months. One transferred nail was found in poor appearance (not flat), the rest of the reconstructed digits were good in appearance and function. The nail, finger print and fine sensation (TPD 5~8 mm), as well as digital flexion, extension, grasping and opposition of the reconstructed digits were all good. According to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association, at the last follow-up visit, 5 digits were in excellent, 4 in good and 1 in fair.Conclusion:The comprehensive reconstruction of grades Ⅰ-Ⅱ digital defects with hallux osteo-onychocutaneous flap of great toe is an ideal surgical technique that can reconstruct the nail, finger print and sensation of a digit, with good postoperative function as well as an aesthetic and realistic appearance.
