Objective To investigate the effect of Miao medicine Jinwu Jiangu decoction containing serum freeze-dried powder on levels of IL-17,ACT1 and TRAF6 in human rheumatoid arthritis fibroblast like synoviocytes (RA-HFLS).Methods Rabbits were randomly divided into blank control group (recieving normal saline of the same volume),Jinwu Jiangu decoction high-dose,medium-dose and low-dose group (intragastrically administrated with Jinwu Jiangu decoction at doses of 14.4,4.8 and 2.4 g·kg-1,respectively),tripterygium glycosides group and prednisone group (treated with human equivalent dosage).RA-HFLS primary cell model was established in the experiment.ELISA method was used to detect effect of lyophilized powder on IL-17 secretion.Expression of ACT1,TRAF6 mRNA was detected by RT-PCR.Results Compared with the blank control gorup,IL-17 in the supernatant of each medication administration group was significantly decreased (all P<0.01),and it was decreased most significantly in Jinwu Jiangu decoction high-dose and medium-dose group.IL-17 was down-regulated more significantly in high-dose group than that in tripterygium glycosides group (P<0.01).Compared with the blank control group,TRAF6 and ACT1 mRNA expression level of each medication administration group were significantly decreased (all P<0.01),and in the high-dose group that were decreased most significantly,but not significantly different as compared with tripterygium glycosides group and prednisone group (P>0.05).Conclusion Freeze-dried powder of Jinwu Jiangu decoction can decrease the secretion of IL-17 and down-regulate expression of ACT1,TRAF6 with RA-HFLS.

Objective To investigate the risk factors for inflammatory complications after radical gastrectomy for gastric cancer and construct a nomogram model for risk prediction. Methods The clinical data of 402 patients with primary gastric cancer who underwent radical gastrectomy were retrospectively analyzed. All patients underwent preoperative Nutritional Risk Screening 2002 (NRS2002) score, Patient-Generated Subjective Global Assessment (PG-SGA) grading, Lumbar 3 Skeletal Muscle Index (L3-SMI) assessment, and serological index testing. Univariate analysis was used to screen for influencing factors of postoperative inflammatory complications of gastric cancer, and multivariate Logistic regression analysis was conducted to determine independent risk factors. A nomogram model for predicting postoperative inflammatory complications after radical gastrectomy was constructed based on the results of multivariate Logistic regression analysis, and the predictive performance of the model was evaluated using the receiver operating characteristic (ROC) curve and calibration curve. Results Univariate analysis revealed that age, TNM stage, body mass index, preoperative hemoglobin, preoperative albumin, preoperative globulin, NRS2002 score, PG-SGA grade, and L3-SMI were influencing factors of postoperative inflammatory complications in patients undergoing radical gastrectomy (P < 0.05). Multivariate Logistic regression analysis showed that age ≤60 years, preoperative hemoglobin ≤130 g/L(male) or ≤115 g/L(female), TNM staging of Ⅳ stage, NRS2002 score≥3, and L3-SMI ≤52.4 cm²/m²(male) or ≤38.5 cm²/m²(female) were independent risk factors for postoperative inflammatory complications in gastric cancer patients (P < 0.05). A nomogram model was constructed based on age, preoperative hemoglobin, TNM stage, and NRS2002 score. The ROC curve showed that the area under the curve of the nomogram model was 0.930, with sensitivity and specificity of 93.2% and 89.2%, respectively. The calibration curve demonstrated good consistency between the predicted probability of inflammatory complications and the actual outcomes. Conclusion Age≤60 years, low preoperative hemoglobin, TNM staging of Ⅳ stage, NRS2002 score ≥3, and low L3-SMI are independent risk factors for postoperative inflammatory complications in gastric cancer patients. The nomogram model constructed based on age, preoperative hemoglobin, TNM stage, and NRS2002 score can accurately predict postoperative inflammatory complications after gastrectomy for gastric cancer.

Objective To construct the rheumatoid arthritis fibroblast-like synoviocytes(RAFLS)model,and to investigate the effects of usnic acid on the inflammatory pathway of high-mobility group protein B1(HMGB1)/receptor for activated glycation end products(RAGE)and the expression levels of vascular en-dothelial growth factor(VEGF),interleukin(IL)-6 and IL-1β.Methods The patients with RA undergoing joint replacement surgery in the orthopedic department of the Second Affiliated Hospital of Guizhou Universi-ty of Traditional Chinese Medicine were selected and the synovial tissues were obtained during operation.The cells were divided into the blank control group(fetal calf serum),solvent control group(fetal calf serum+10％hydroxypropyl betacyclodextrin),usnic acid high dose group(usnic acid 50 μg/mL),usnic acid middle dose group(usnic acid 10 μg/mL),usnic acid low dose group(usnic acid 2.5 μg/mL)and hydroxychloroquine group(hydroxychloroquine 50 mmol/L).The cell proliferation after different concentrations of usnic acid treatment was detected by MTT,the HMGB1 and RAGE protein expression in cells of each group was detec-ted by Western blot,and the expression levels of HMGB1,VEGF,IL-6 and IL-1β were detected by ELISA.Re-sults Compared with the blank control group,the proportions of cellular apoptosis in the usnic acid high,middle and low doses groups and hydroxychloroquine group were increased(P＜0.05);the expression levels of HMGB1 and RAGE protein in the usnic acid high,middle and low doses groups and hydroxychloroquine group were significantly decreased(P＜0.05),the expression levels of HMGB1,VEGF,IL-6 and IL-1β were decreased(P＜0.05);compared with the hydroxychloroquine group,the cellular apoptosis proportions of the usnic acid high,middle and low doses groups were decreased(P＜0.05),the HMGB1 protein expression level in the usnic acid low dose group was significantly increased(P＜005),the RAGE protein expression level in the the usnic acid middle amd low doses groups was significantly increased(P＜0.05).Conclusion Usnic acid alleviates the inflammatory reaction of synoviocytes possibly by regulating HMGB1/RAGE inflammatory pathway and VEGF,IL-6 and IL-1β inflammatory factors expression levels.
