ObjectiveTo investigate the inhibitory effects and mechanisms of Yupingfeng San （YPFS） on high-mobility group box protein 1 （HMGB1）-induced angiogenesis in liver cancer. MethodsAn orthotopic liver cancer model was established in 30 C57BL/6 mice. The mice were randomly divided into a model group， YPFS low-， medium-， and high-dose groups （20， 30， 40 g·kg^-1， respectively）， a positive control group （sorafenib， 10 mg·kg^-1）， and a normal control group. After 14 days of medication， tumor and adjacent tissues were harvested. Tumor inhibition rates were calculated based on tumor weight. Microvascular density was determined via immunohistochemistry. HMGB1 and vascular endothelial growth factor （VEGF） expression levels were determined using immunofluorescence. An HMGB1-induced human umbilical vein endothelial cell （HUVEC） proliferation model was established， and cell proliferation was evaluated by a methylthiazolyldiphenyl-tetrazolium bromide （MTT） assay. HUVECs were randomly divided into a blank group， a model group （HMGB1 800 μg·L^-1）， along with YPFS low-， medium-， and high-dose groups （HMGB1 800 μg·L^-1 + YPFS 10， 30， 50 g·L^-1， respectively）. HUVEC migration ability was evaluated via a scratch assay and a Trans well chamber assay. Tube formation ability was detected by a tube formation assay. Microvascular sprouting ability was evaluated by an aortic ring assay. Furthermore， RAGE/MEK1/2/ERK1/2 pathway-related protein expression in HUVECs was measured using Western blot （WB）. ResultsCompared with the model group， all three doses of YPFS significantly reduced tumor weight in mice with orthotopic liver cancer （P<0.01）， with inhibition rates of 31.49% ± 8.27%， 49.60% ± 3.77%， and 56.81% ± 9.70%， respectively. Also， YPFS significantly decreased microvascular density in tumor and adjacent tissues （P<0.05）， as well as VEGF and HMGB1 expression levels （P<0.01）. Compared with the blank group， HMGB1 promoted HUVEC proliferation， migration， tube formation， and microvascular sprouting in aortic rings （P<0.05）. After YPFS administration， the HMGB1-induced proliferation rate， migration rate， number of tube formations， and microvascular sprouting in aortic rings were significantly reduced compared with the model group （P<0.01）. Additionally， YPFS downregulated receptor for advanced glycation end products （RAGE）， mitogen-activated protein kinase kinase 1/2 （MEK1/2）， phosphorylated MEK1/2 （p-MEK1/2）， extracellular signal-regulated kinase 1/2 （ERK1/2）， and phosphorylated ERK1/2 （p-ERK1/2） protein expression in HMGB1-induced HUVECs （P<0.01）. ConclusionYPFS exerts anti-angiogenic effects against HMGB1 induction by suppressing the RAGE/MEK/ERK signaling pathway， thereby inhibiting liver cancer tumor growth.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To investigate relationship between IL-17/IL-23 immunoinflammatory axis and chronic heart failure(CHF)and clinical prognosis.Methods:A total of 112 patients with CHF in Chengde Central Hospital from January 2020 to Septem-ber 2021 were selected as observation group,and another 112 patients admitted to same period for healthy physical examination were selected as control group.Serum IL-17 and IL-23 levels of two groups were compared,relationship between serum IL-17 and IL-23 levels and degree of disease were analyzed;clinical data,serum IL-17 and IL-23 levels of patients with different prognosis were compared,relationship between serum IL-17 and IL-23 levels and clinical prognosis of CHF patients were analyzed.Predictive value of serum IL-17 and IL-23 levels on clinical prognosis of CHF patients was evaluated,and predictive value of each prediction scheme was compared.Results:Serum IL-17 and IL-23 levels were higher in observation group than control group(P<0.05);serum IL-17 and IL-23 levels of CHF patients were positively correlated with NYHA classification(P<0.05).Serum IL-17 and IL-23 levels were higher in patients with poor prognosis than in those with good prognosis(P<0.05).Serum IL-17 and IL-23 were independently associated with clinical prognosis of CHF patients,and the higher the serum IL-17 and IL-23 levels,the greater risk of poor clinical prognosis of CHF patients.AUC of serum IL-17 and IL-23 levels for predicting clinical prognosis of CHF patients were 0.787 and 0.726,respectively,and combined predicted AUC was 0.918(P<0.001);combined predicted AUC of serum IL-17 and IL-23 was significantly higher than single index(P<0.05).Conclusion:IL-17 and IL-23 levels in IL-17/IL-23 immunoinflammatory axis of CHF patients are significantly elevated and involve in disease occurence and development,whose clinical detection can help predict clinical prognosis of CHF.

There is a substantial unmet need for treatments in the field of pediatric rare diseases, and investigator initiated trial(IIT) provide a critical pathway for testing and developing new drugs or treatment strategies. However, healthcare institutions, when conducting such research, must address compliance risks related to project approval, contract management, data protection, and conflict of interest management. This study aims to analyze the particularities and challenges of IIT in pediatric rare diseases, review relevant regulations and regulatory requirements, and provide healthcare institutions with a reference framework for compliance risk management to maximize the benefits of IIT. Based on literature review, analysis of laws and regulations, practical work experience, and frameworks from other institutions, we summarize the unique aspects of pediatric rare disease IIT in terms of participant characteristics, innovative technologies, and organizational structures.On this basis, targeted compliance management recommendations are proposed, which include establishing a risk rating and full-cycle risk monitoring mechanism, a consent and ethical review mechanism tailored to pediatric participants, a robust contract management mechanism, a comprehensive data security management mechanism, and a multidisciplinary team and multi-channel compensation mechanism. The study concludes that healthcare institutions, funders, and other collaborating entities should implement compliance management in line with the characteristics of IIT to ensure the safety and effectiveness of research and facilitate innovation and development in the treatment of pediatric rare diseases.

Objective To explore the regulatory effect of moderate intensity aerobic exercise on glu-cose and lipid metabolism disordersafter immune stimulation in high-fat diet induced insulin resistance(IR)mice by inducing tolerance of trained immunity.Methods Eighteen of 70 male C57BL/6 male mice were randomly selected as the control group(CON group),while the remaining mice were subjected to high-fat diet intervention(HFD group)for 8 weeks.After modeling,six of the CON group and HFD group were measured their glucose and lipid metabolism and inflammation levels.The remaining mice in the HFD group were randomly divided into HFD sedentary group(HS group)and HFD exer-cise group(HE group),each of 16.The HE groups underwent a daily 60-minute running on a hori-zontal treadmill at 12 m/min,5 days a week for 8 weeks.After that,the CON,HS and HE groups were randomly divided into an immune stimulation group(lipopolysaccharides,LPS group)and a con-trol group(phosphate buffered saline,PBS group),with 6 in CON-PBS and CON-LPS groups,and 8 in HS-PBS,HS-LPS,HE-PBS and HE-LPS groups.The LPS group received intraperitoneal injec-tion of LPS as an immune stimulus,and were taken samples 24 hours after intervention.During the intervention period,the body weight,food intake,fasting blood glucose(FBG),glucose tolerance,and insulin tolerance were tested for all groups.Then,the serum blood lipid level was tested.More-over,the levels of tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1β)and interleukin-10(IL-10)in serum were detected by using the enzyme-linked immunosorbent assay,while the protein expression of IL-1β,IL-10,induciblenitricoxidesynthase(iNOS)andarginase-1(Arg-1)were measured by using Western Blot.Results(1)After 8 weeks of high-fat diet intervention,compared with the CON group,there was a significant increase in the body weight,food intake,and FBG,the level of TNF-α and IL-1β in serum and expressions of IL-1β and iNOS in liver,skeletal muscle and adipose tissue,but a significant decrease in glucose and insulin tolerance,the level of anti-in-flammatory factor IL-10,as well as IL-10 and Arg-1 in liver and Arg-1 in adipose tissues in group HFD(P<0.01,P<0.05).(2)After 8 weeks of diet intervention,the body weight of group HS-PBS was still significantly higher than group CON-PBS(P<0.01).However,no significant differences were found between group CON-PBS and HS-PBS in other indicators(P>0.05).After LPS intervention,the food intake of both CON-LPS and HS-LPS groups was significantly lower than the corresponding PBS group(P<0.05).However,the levels of FBG,TG,TC,LDL-C,TNF-α and IL-1β in serum,IL-1β and iNOS in liver and adipose tissues,and iNOS in skeletal muscles of group HS-LPS were signif-icantly higher compared with group HS-PBS and CON-LPS(P<0.05).Meanwhile,the levels of IL-10 in serum,skeletal muscles and adipose tissues,and Arg-1 in skeletal muscles and adipose tissues of group HS-LPS decreased significantly compared with group HS-PBS and CON-LPS(P<0.05).(3)Af-ter simultaneous aerobic exercise intervention,there were no significant differences between group HE-LPS and HE-PBS in FBG,TC,LDL-C,TNF-α,IL-1β and IL-10 in serum,as well as IL-1β,iN-OS and IL-10 in the liver,skeletal muscles and adipose tissues(P>0.05).Moreover,thelevels of FBG,TG,TC,TNF-α,IL-1β in serum,and IL-1β and iNOS in the liver,skeletal muscle and adi-pose tissue decreased significantly in group HE-LPS compared with group HS-LPS(P<0.05).Howev-er,the levels of IL-10 in the serum and liver,and IL-10 and Arg-1 in skeletal muscles and adi-pose tissues increased significantly in group HE-LPS compared with group HS-LPS(P<0.05).Conclu-sion Eight-week aerobic exercise can effectively relieve the glucose and lipid metabolism disorder after immune stimulation in IR mice,which may be related to the stimulation of immunologic tolerance in innate immune cells,thereby reducing the excessive inflammatory response caused by secondary im-mune stimulation.
