Objective:To construct the inflammation score(IS)and nutrition-immunity score(NIS)for patients with multiple myeloma(MM),and to verify their prognostic stratification effects and significance.Methods:The clinical data of 129 newly diagnosed MM patients admitted to our hospital from August 2011 to September 2022 were retrospectively analyzed.Univariate and multivariate Cox regression analysis of overall survival(OS)were comducted on clinical parameters,including inflammatory indicators such as red blood cell volume distribution width(RDW)and platelet count(PLT),nutritional-immune indicators such as albumin(ALB),absolute lymphocyte count(ALC),and suppressed immunoglobulin count(S-Ig count).To construct IS and NIS for prognosis,X-tile software and multivariate Cox regression analysis were used to verify the prognostic stratification role and significance of IS and NIS.The time-dependent receiver operating characteristic(ROC)curve,C-index curve,calibration curve,and decision curve analysis(DCA)were used to evaluate the discrimination,accuracy,and clinical net benefit of IS and NIS in predicting overall survival(OS),and compared to the international staging system(ISS).Results:IS was constructed based on the scores of RDW and PLT,and NIS was constructed based on the scores of ALB,ALC,and S-Ig count.According to X-tile analysis and multivariate Cox regression analysis,IS and NIS can divide the patients into three risk strata respectively:low,medium and high IS and NIS groups.The differences in OS and hazard ratio(HR)between the low,medium,and high strata were statistically significant(P＜0.05).IS and NIS are both independent prognostic predictors for MM.The area under the ROC curve(AUC)and C index of IS and NIS for predicting 1-to 7-year OS were greater than those of ISS,and both were greater than 0.7.The prediction results of IS and NIS for 1-,3-,and 5-year OS rates were well consistent with the actual observed results.The DC A curves of IS and NIS for predicting 1-,3-,and 5-year OS were higher than that of ISS in a wide range of threshold probability intervals.Conclusion:IS and NIS have independent predictive significance for OS in MM patients.Their predictive discrimination,accuracy,and clinical net benefit are higher and better than ISS,and they may have potential application value in MM prognosis.

Aim To study whether intravenous injec-tion of miR-129-3p mimetic(agomir)can resist bone loss caused by hind limb disuse,and to provide new i-deas for preventing bone loss in microgravity environ-ment.Methods Forty-eight C57BL/6J male mice were randomly divided into the control group(CON),tail suspension model group(TS),tail suspension+miR-129-3p agomir administration group(miRNA)and tail suspension+miR-129-3p negative sequence agomir control group(NC).The miRNA group was given 4 mg·kg-1 miR-129-3p agomir by intravenous injection into the medial canthus twice a week.The NC agomir group were consistent with those in the miR-129-3p agomir group,and the CON and TS groups were given only equal volumes of normal saline.After four weeks,all mice were sacrificed and samples were collected.Micro-CT scan of femur,three-point femur bending test,serum bone metabolism index detection,oxidative stress index detection and osteogenesis-related protein expression analysis in bone tissue were per-formed.Results After four weeks,the number of tra-becular bone in the TS group was significantly re-duced,and Tb.BMD,Tb.Th,Tb.N,Tb.BS/TV and Tb.BV/TV were significantly lower than those in the CON group(P＜0.01).While Tb.Sp TS group was significantly higher than the CON group(P＜0.05),the maximum load and flexural strength of the femur significantly decreased(P＜0.01),the content of ser-um bone formation index PINP was significantly lower than that of the CON group(P＜0.01),and the con-tent of bone resorption index CTX-I was significantly higher than that of the CON group(P＜0.01),the content of serum oxidative damage indexes 8-iso-PGF2α and 8-OHdG significantly increased(P＜0.01),and the expression of osteogenesis-related pro-teins in bone tissue markedly decreased(P＜0.01).However,the increase or decrease of all indexes in miRNA group was significantly lower than that in TS group.Conclusions miR-129-3p mimetic can signifi-cantly reduce bone loss caused by hind limb disuse.This experiment provides a new idea and method for preventing bone loss in microgravity environment.

Objective To investigate the ameliorative effects and mechanisms of six types of tea(green tea,cyan tea,red tea,white tea,black tea and yellow tea)on metabolic disorders in obesity mice induced by high-fat diet(HFD).Methods Four-week-old male C57BL/6J mice were randomly divided into 8 groups with 7 mice per group.An HFD-induced obese mouse model was established,and the mice in control group maintained on standard diet followed by intragastric administration of different teas for 5 weeks.The body weight,liver weight ratio,fasting blood glucose,and lipid profile of the mice were measured to assess glucose and lipid metabolism.Serum inflammatory factors including IL-6,tumor necrosis factor-alpha(TNF-α)and oxidative stress markers[malondialdehyde(MDA)and superoxide dismutase(SOD)were measured.Additionally,liver histopathology and the expression of key glycolipid metabolism-related genes,adenosine monophosphate-activated protein kinase(AMPK)and carnitine palmitoyltransferase 1(CPT-1),were analyzed to explore underlying mechanisms.Results Cyan tea significantly suppressed weight gain,demonstrating superior weight control.White tea markedly reduced fasting blood glucose levels and decreased the area under the curve of oral glucose tolerance test(OGTT)and insulin tolerance test(ITT),indicating synergistic improvements in glucose metabolism and insulin sensitivity.Yellow tea exhibited exceptional anti-inflammatory and antioxidant effects,reducing hepatic IL-6 and MDA while enhancing SOD activity.Green tea activated the lipid oxidation pathway by upregulating AMPK/CPT-1 expression.All kinds of tea significantly attenuated hepatic lipid droplet accumulation.Conclusion All six types of tea alleviated metabolic disorders by reducing hepatic fat content in obesity mice.However,different types of tea exert their unique effects on improving metabolic disorders through differential mechanisms such as glucose metabolism regulation,lipid oxidation,and anti-inflammatory and antioxidant actions.

Bilirubin,as a major endogenous substance in the human body,plays anti-inflammatory,antioxidant,and cytoprotective roles within physiological ranges,serving a critical function in maintaining metabolic balance of endogenous substances.Bilirubin metabolism is a complex physiological process regulated by multiple factors,relying on UGT1A1 enzyme catalysis and transporter protein modulation to sustain substance homeostasis.Based on the theory of traditional Chinese medicine(TCM)channel tropism and the principle of visceral syndrome differentiation,liver-channel-tropic herbs can guide medications to specific viscera and meridians,exerting targeted therapeutic effects.These herbs regulate bilirubin metabolic disorders through multi-target mechanisms,including upregulating UGT1A1 enzyme activity to promote bilirubin conjugation,modulating MRP2/OATP expression to enhance bilirubin transport,attenuating oxidative stress to reduce hepatocyte damage,inhibiting inflammatory cytokines to restore metabolic enzyme activity,activating CAR signaling pathways to regulate bile acid homeostasis.This review summarizes the mechanisms by which TCM regulates bilirubin metabolism,focuses on the role of liver meridian-targeting TCM to provide a basis for its rational clinical use,and studies the effects of liver meridian-targeting TCM on bilirubin metabolism from its core mechanisms to guide its rational use and provide new ideas for the research and development of traditional Chinese medicine.This review summarizes the mechanisms by which TCM regulates bilirubin metabolism,focusing on the actions of herbs that enter the liver meridian.Starting from the core mechanisms,it explores how liver meridian-entering herbs significantly impact bilirubin metabolism.Some of these herbs demonstrate dual-directional regulatory effects on bilirubin metabolism.This understanding guides their rational clinical use,provides novel ideas for TCM research and development,and promotes the modernization of TCM studies.
