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 evaluate the clinical efficacy of botulinum toxin type A (BTX-A) combined with sodium hyaluronate solution for facial microdroplet injection in improving facial skin photoaging.Methods:A prospective randomized controlled trial was conducted. From January to July 2024, patients with facial photoaging problems were recruited from the Plastic Surgery Department of the Affiliated Hospital of Xuzhou Medical University and randomly divided into a monotherapy group (sodium hyaluronate solution droplet injection) and a combination therapy group (BTX-A + sodium hyaluronate solution droplet injection) by hierarchical block randomization method. The treatment regimen was 3 months, with one treatment for each month, with a total of 3 treatment. The combination therapy group only used a combination therapy of two drugs (BTX-A 25 U+ 5 ml sodium hyaluronate solution) during the first injection. During the three treatments of the monotherapy group and the second and third treatments of the combination therapy group, 5 ml of sodium hyaluronate solution was injected as the solo ingredient. Follow up was conducted at 1, 2, and 4 months after the last treatment. Serum superoxide dismutase (SOD) activity and malondialdehyde (MDA) levels were detected by test kit. Five skin texture indicators (moisture content, transepidermal water loss rate, elasticity, glossiness, and pH) were evaluated using the German CK skin tester. VISIA skin detector was used for facial two-dimensional photography and skin condition analysis. Clinical efficacy (significant improvement, obvious improvement, improvement, no improvement) and global aesthetic improvement scale (GAIS) scores on a 5-point scale were recorded. Patient satisfaction levels (very satisfied, satisfied, and dissatisfied) were investigated. The data were analyzed using SPSS 27.0 software. Count data was presented as examples and(or) percentages, and analyzed using a chi-square test. Normal distribution measurement data was represented by Mean±SD and analyzed using t-test. Results:A total of 100 patients were included, with 50 cases in each group. There were 17 males and 33 females in the monotherapy group, with an age of (31.3±7.1) years, and there were 5, 14, 29 and 2 patients in the Ⅰ to Ⅳ types of Glogau skin photoaging classification, respectively. There were 15 males and 35 females in the combination therapy group, with an age of (32.1±8.4) years old, and there were 4, 15, 27 and 4 patients in the Ⅰ to Ⅳ types of Glogau skin photoaging classification, respectively. There was no statistically significant difference in gender composition, age, and Glogau skin photoaging classification between the two groups (all P>0.05). One month after the first treatment, both groups showed an increase in SOD activity and a decrease in MDA levels, with more significant changes observed in the combination therapy group ( P<0.01 for both). At the follow-up of 1, 2, and 4 months after the last treatment, the combination therapy group outperformed the monotherapy group in all 5 skin texture indicators (all P<0.05). One month after the last treatment, the total effective rate of the combination therapy group was 76.0% (38/50), which were significantly higher than that of the monotherapy group’s 50.0% (25/50) ( P<0.05); in addition, the combination therapy group showed significant advantages in facial aesthetic GAIS scores, as well as patient satisfaction, with a satisfaction rate of up to 98.0% (49/50), which was higher than the 88.0% (44/50) of the monotherapy group ( P<0.01). Throughout the entire treatment process, neither group experienced serious adverse reactions. Conclusion:Facial microdroplet injection of BTX-A combined with sodium hyaluronate solution effectively improves symptoms of facial skin photoaging, enhancing skin hydration and elasticity, reducing transepidermal water loss, improving skin gloss, regulating skin pH, and enhancing skin antioxidant capacity, ultimately achieving facial skin rejuvenation. This method is safe, effective and holds high clinical relevence and patient satisfaction.

Objective: To explore the expression of collagen type 1 alpha 2 (COL1A2) in cervical cancer and its correlation with immune infiltration. Methods: Bioinformatics techniques were used to analyze the expression of COL1A2 in cervical cancer. Western blot and RT-qPCR were used to detect the expression of COL1A2 in cervical cancer tissues and cell lines. The correlation between the expression of COL1A2 and tumor immune cell infiltration was analyzed by tumor immune estimation resource (TIMER2. 0) . Gene set enrichment analysis (GSEA) was used to analyze the possible mechanism of COL1A2 in cervical cancer. Jaspar database was used to predict the transcrip- tion factors of COL1A2. Western blot and RT-qPCR were used to detect the expression of transcription factors in cervical cancer tissues and cell lines. Results: The expression of COL1A2 was down-regulated in cervical cancer (P < 0. 05) . The expression of COL1A2 was positively correlated with the levels of macrophages and myeloid den- dritic cells (P < 0. 01) . The proportions of 22 types of immune cells were different in different cervical cancer pa- tients. In addition , compared with the high expression group of COL1A2 , the proportion of M0 macrophages , M2 macrophages and resting memory CD4 + T cells increased in the low expression group of COL1A2 , while the propor- tion of CD8 + T cells , activated memory CD4 + T cells , follicular helper T cells , activated NK cells and activated myeloid dendritic cells decreased (P < 0. 05) . GSEA analysis showed that COL1A2 was related to immune-related signaling pathways , including Notch signaling pathway , interleukin-6/janus kinase/signal transducer and activator of transcription 3 (IL6/JAK/STAT3) , Wnt/β-catenin signaling pathway , etc. (P < 0. 01) . Jaspar database pre- dicted that the transcription factor of COL1A2 was paired box protein 5 (PAX5) , and the expression of PAX5 de- creased in cervical cancer (P < 0. 05) . Conclusion COL1A2 is expected to become a potential diagnostic biomar- ker and immunotherapy target for cervical cancer.

Objective:To investigate the immunological mechanism by which grifola frondosa extract improves colonic tissue inflammation in rats with ulcerative colitis(UC)through the sphingosine kinase 1(SPHK1)/sphingosine-1-phosphate(S1P)signaling pathway.Methods:Forty male SD rats were randomly divided into five groups:blank group,model group,sulfasalazine treatment group(SASP group),grifola frondosa extract treatment group(GF group),and sulfasalazine combined with grifola frondosa extract treatment group(SASP+GF group).UC model was established using a 3%dextran sulfate sodium(DSS)free drinking method.After one week,each treatment group received sulfasalazine 0.3 g/(kg·d),grifola frondosa extract 10 mg/(kg·d),and combination of both drugs by gavage.During the experiment,the general condition of the rats was observed,the disease activity index(DAI)score was re-corded and the protein content and positive expression levels of SPHK1,S1P,tumor necrosis factor receptor-associated factor 2(TRAF2)and TNF-α in rat colon tissue were detected by immunohistochemistry.mRNA and protein expression levels of SPHK1,S1P,TRAF2 and TNF-α in rat colon tissue were measured by RT-qPCR and Western blot.Results:Compared with the blank group,the general condition of the model group rats were poor,the DAI score was significantly increased,and the protein positive expres-sion,mRNA and protein expression levels of SPHK1,S1P,TRAF2 and TNF-α in colon tissue were significantly increased(P<0.01).Compared with the model group,the general condition of the rats in each treatment group improved significantly,the DAI score was decreased(P<0.01),and the positive expression of each target protein was significantly reduced(P<0.01),especially in the GF group and SASP+GF group;the mRNA and protein expression levels of SPHK1 and TRAF2 were reduced to varying degrees(P<0.01 or P<0.05),while the mRNA and protein expression levels of S1P and TNF-α only decreased significantly in the GF group and SASP+GF group(P<0.01).Compared with the SASP group,the GF group only showed a decrease in SPHK1 protein expression,TNF-α mRNA,and protein expression levels,while the SASP+GF group showed significant reductions in all targets(P<0.01 or P<0.05).Compared with the GF group,the SASP+GF group showed significant reductions in SPHK1 protein positive expression and content,S1P mRNA expression levels,and TNF-α protein content(P<0.05 or P<0.01).Conclusion:Grifola frondosa extract may alleviate co-lonic tissue inflammation in rats with UC by inhibiting the activation of the SPHK1/S1P pathway,restoring intestinal mucosal barrier function,and improving symptoms of UC.

Objective To study the key genes and immune biomarkers of gout and to explore potential target Chinese medicine,which can provide new directions for the clinical treatment of gout.Methods The gout microarray dataset was downloaded from the GEO database,the differential genes were screened using R software,and Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were performed on these differential genes.The STRING database was applied to analyze the protein interaction network of the differential genes,and the Cytoscape was used to screen the key genes.The protein expression levels of key genes were validated using the ELISA method.Furthermore,the xCell was used to estimate the relative expression and correlation of immune cells in gout.Finally,the significantly enriched immune-related biological processes and key target genes of Chinese medicine were predicted by Coremine Medical database.Results A total of 852 differential gout genes were screened.GO enrichment analysis was mainly enriched in the leukocyte chemotaxis,interleukin-2 production,and regulation of vasculature development;KEGG pathway was mainly enriched in IL-17 signaling pathway,Chemokine signaling pathway,and TNF signaling pathway.Ten key genes,including TNF,IL-6,IL-1β,CXCL8,FOS,and VEGFA etc,were selected.The experimental validation showed that the protein expression levels of key genes were consistent with the expression trends of the chip data.Immune infiltration showed that monocytes,memory B cells,CD8+T-cells and IDC were closely associated with gout.Herbal predictions had identified Ginseng,Panax notoginseng,Scutellaria,Baicalensis,Saururus chinensis,and Salvia miltiorrhiza as potential drugs for the treatment of gout.Conclusion This study identified possible key genes and immune mechanisms contributing to the pathogenesis of gout,and discovered potential targetable traditional Chinese medicine.These key genes and herbs are expected to offer new insights and methods for the treatment of gout.

Objective:Proximal femur tumor resection often leads to hip joint instability and functional loss.Various methods have been clinically applied to repair hip joint soft tissue function,but deficiencies remain.This study aims to evaluate the advantages and disadvantages of the ligament advanced reinforcement system(LARS)tumor tube in assisting soft tissue function reconstruction in patients undergoing tumor type artificial hip replacement surgery. Methods:This study included 85 patients(41 males,44 females)with proximal femoral tumors treated at the Xiangya Bone Tumor Treatment Center from January 2012 to January 2022,aged 10 to 79(38.5±18.2)years.Among them,13 cases had benign aggressive tumors,45 had primary malignant bone tumors,and 27 had bone metastases.Clinical data,imaging data,and intraoperative photos were collected.Patients were followed up and postoperative functional evaluations were conducted using the Musculoskeletal Tumor Society(MSTS)scoring system and Harris hip joint scoring system to assess limb function and hip joint function. Results:Preoperative pathological fractures were present in 37 cases(43.5％),with a lesion length of(9.4±2.9)cm.Among non-metastatic tumor patients,7 experienced postoperative recurrence,including 6 cases of osteosarcoma and 1 case of fibrosarcoma.Pulmonary metastases occurred in 9 osteosarcoma patients.Five patients required reoperation due to postoperative complications,including 3 cases of deep vein thrombosis,1 case of giant cell granuloma,and 1 case of prosthesis infection.Postoperatively,5 patients exhibited Trendelenburg gait,and 6 had leg length discrepancies.The postoperative MSTS score was 26.7±1.4,and the Harris score was 89.6±5.3. Conclusion:The LARS tumor tube can effectively assist in reconstructing the soft tissue function of the hip joint and greatly reduce postoperative complications,making it an effective technical improvement in joint function reconstruction in tumor type artificial hip replacement surgery.
