Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

Compared with acute pancreatitis caused by other factors， hyperlipidemic acute pancreatitis often has a higher rate of severe conditions， greater difficulties in predicting prognosis， and a more complex and unclear pathogenesis. At present， the pathogenesis of hyperlipidemic acute pancreatitis may be associated with the elevation of serum free fatty acids， but the lipid-lowering treatment regimens do not reduce the incidence rate of this disease. Recent studies have further confirmed that pancreatic duct hypertension is an important pathogenesis of acute pancreatitis. The latest research advances have shown that hyperlipidemia can lead to pancreatic duct obstruction by causing pancreatic duct hyperplasia， forming protein embolism at the biliary-pancreatic junction， and damaging the secretory function of the pancreatic duct， while pancreatic duct obstruction can in turn cause pancreatic duct obstruction. This article reviews the latest research advances in hyperlipidemia in causing pancreatic duct obstruction and emphasizes that pancreatic duct hypertension is one of the important pathogeneses of hyperlipidemic acute pancreatitis， which will provide new ideas for exploring the pathogenesis of hyperlipidemic acute pancreatitis.

Objectives:To assess the effectiveness and safety of ivabradine for the treatment of chronic heart failure in the context of the new quadruple combination. Methods:Clinical data of 656 chronic heart failure patients hospitalized in Nanjing Drum Tower Hospital from March 2021 to June 2022 were retrospectively collected,and the patients were divided into control group(n=361)and observation group(n=295)according to ivabradine use,and both groups were treated with the new quadruple drug therapy.Propensity score matching was performed,268 patients in the observation group and 268 patients in the control group were successfully matched.The effectiveness(primary endpoint was the composite endpoint of cardiovascular death and rehospitalisation for worsening heart failure within 1 year of discharge;secondary endpoints were rehospitalisation for worsening heart failure,all-cause rehospitalisation,cardiovascular death,and all-cause death)and safety outcome measures(including bradycardia,atrial fibrillation,blurred vision,renal impairment,and hypertension)were compared between the two groups at 1 year after treatment. Results:After matching,there were no statistically significant differences at baseline characteristics between the two groups.Kaplan-Meier survival curve showed that the occurrence rates of primary endpoints(P=0.031),readmission for worsening heart failure(P=0.020),and all-cause readmission(P=0.036)were lower in the observation group than in the control group.Multivariate Cox proportional hazard regression analysis showed that the occurrence rates of primary endpoint events(P=0.045)and readmission for heart failure worsening(P=0.028)were lower in the observation group than in the control group. Conclusions:The ivabradine use on top of the new quadruple therapy regimen in patients with chronic heart failure is beneficial to improve one-year prognosis with favorable safety profile.

Objective:To explore the effective indicators that can predict the poor prognosis of neonates with congenital heart disease after surgery.Methods:178 cases of neonatal congenital heart disease were retrospectively analyzed. According to the outcome, they were divided into normal prognosis group (132 cases) and poor prognosis group (46 cases).Results:15 (8.4%) patients died in hospital. There were statistical differences between the two groups in terms of whether PGE and vasoactive drugs were needed before surgery, preoperative respiratory support mode, blood lactate level from anesthesia induction to 24 h after surgery, VIS and VVR scores, whether delayed sternal closure or peritoneal dialysis were needed ( P<0.05). Logistic regression analysis showed that elevated lactate levels and VVR scores on 24 h after surgery were independent risk factors for death or other poor postoperative prognosis in neonates ( P<0.05). Conclusion:The levels of lactate and VVR scores in 24 h after operation are sensitive indicators for monitoring the severity of the condition, guiding treatment and judging prognosis of neonatal congenital heart disease surgery.

Objective:To investigate the correlation factors of complete clinical response in idiopathic inflammatory myopathies(IIMs)patients receiving conventional treatment.Methods:Patients diagnosed with IIMs hospitalized in Peking University People's Hospital from January 2000 to June 2023 were in-cluded.The correlation factors of complete clinical response to conventional treatment were identified by analyzing the clinical characteristics,laboratory features,peripheral blood lymphocytes,immunological indicators,and therapeutic drugs.Results:Among the 635 patients included,518 patients finished the follow-up,with an average time of 36.8 months.The total complete clinical response rate of IIMs was 50.0％(259/518).The complete clinical response rate of dermatomyositis(DM),anti-synthetase syn-drome(ASS)and immune-mediated necrotizing myopathy(IMNM)were 53.5％,48.9％and 39.0％,respectively.Fever(P=0.002)and rapid progressive interstitial lung disease(RP-ILD)(P=0.014)were observed much more frequently in non-complete clinical response group than in complete clinical re-sponse group.The aspartate transaminase(AST),lactate dehydrogenase(LDH),D-dimer,erythrocyte sedimentation rate(ESR),C-reaction protein(CRP)and serum ferritin were significantly higher in non-complete clinical response group as compared with complete clinical response group.As for the treat-ment,the percentage of glucocorticoid received and intravenous immunoglobin(IVIG)were significantly higher in non-complete clinical response group than in complete clinical response group.Risk factor analysis showed that IMNM subtype(P=0.007),interstitial lung disease(ILD)(P=0.001),eleva-ted AST(P=0.012),elevated serum ferritin(P=0.016)and decreased count of CD4+T cells in peripheral blood(P=0.004)might be the risk factors for IIMs non-complete clinical response.Conclu-sion:The total complete clinical response rate of IIMs is low,especially for IMNM subtype.More effec-tive intervention should be administered to patients with ILD,elevated AST,elevated serum ferritin or decreased count of CD4+T cells at disease onset.

Objective To investigate the role of homologous genes absent from the wings of drosophila melanogaster(Notch)signaling pathway in the imbalance of helper T cells 1(Th1)and helper T cells 2(Th2)and the intervention mechanism of Qizhi Zhoufei Granule in chronic obstructive pulmonary disease(COPD).Methods Ten of seventy Wistar rats were selected as the blank control group,and the other rats were established by cigarette smoking combined(CS)with tracheal infusion of lipopolysaccharide(LPS).The COPD model was established by randomly selecting 3 rats in the control group and the model group to verify the success of the model.At the end of modeling,gavage administration was performed.The rats in the model group were randomly divided into model control group,positive control group(67.5 μg·kg-1)and Qizhi Zhoufei Granule high,medium and low treatment group(3.24,1.62,0.81 g·kg-1).Each group was treated with normal saline,dexamethasone acetate suspension and Qizhi Zhoufei Granule suspension at high,medium and low doses.The rats in the blank control group were given the same volume of normal saline as the model control group.After modeling with 28 days and treatment with 28 days,peak inspiratory flow(PIF)and peak expiratory flow(PEF)were detected by the animal lung function test system.Rats were killed to extract lungs,spleen,serum and bronchoalveolar lavage fluid(BALF),hematoxylin-eosin(HE)staining was used to evaluate the pathological changes of lung tissues.The level of tumor necrosis factor-α(TNF-α)in serum and BALF was determined by enzyme-linked immunosorbent assay(ELISA).Flow cytometry was used to detect Th1/Th2 cells in spleen.Immunohistochemistry(IHC)and western blot were used to detect Notch1,Hes1 and Hey1 protein levels in lung tissues.Real-time fluorescence quantitative polymerase chain reaction(Real-Time PCR)was used to detect Notch1,Hes1 and Hey1 gene expression levels in lung tissues.Result Compared with the blank control group,the lung function of the model control group was significantly decreased(P<0.05),inflammatory cell infiltration and bronchial structure destruction occurred in the lung tissue,TNF-α content in serum and BALF increased significantly(P<0.05),the percentage of spleen Th1 cells was significantly decreased(P<0.05),and the percentage of Th2 cells was significantly increased(P<0.05),the protein and mRNA expressions of Notch1,Hes1 and Hey1 in lung tissues were significantly increased(P<0.05),the differences were statistically significant;Compared with the model control group,the lung function of rats in each administration group was significantly increased(P<0.05),the pathological injury of lung tissue was alleviated,TNF-α content in serum and BALF decreased significantly(P<0.05),the percentage of spleen Th1 cells was significantly increased(P<0.05),the percentage of Th2 cells was significantly decreased(P<0.05),the lung tissue of Notch1,Hes1,Hey1 protein and mRNA expression were significantly decreased(P<0.05),the differences were statistically significant.Conclusion Qizhi Zhoufei Granule regulate Th1/Th2 balance by inhibiting Notch signaling pathway,thereby improving pulmonary function and pathological injury,and affecting immune function in COPD rats.

BACKGROUND:Osteoporosis is a disease in which bone density and structure are destroyed and fractures are caused by increased bone fragility,leading to high clinical disability and mortality rates. OBJECTIVE:To review the research progress in the role of bone immunity in physiological and pathological processes related to bone metabolism,providing ideas for the research and clinical application of bone immunity in bone diseases. METHODS:The first author searched PubMed and CNKI databases in November 2022 for relevant literature using the keywords of"osteoimmunology,immuno-skeletal interface,bone metabolism,skeletal metabolism,lymphocyte,immune factor"in English and Chinese,respectively.The time range of retrieval was mainly from January 2010 to November 2022,and a small number of classical long-term literatures were included.After reading the topic and abstract for preliminary screening and excluding repetitive studies,low-quality journals and unrelated literature,81 documents were finally included for review. RESULTS AND CONCLUSION:Osteoimmunology refers to that bone and immune cells share the same microenvironment and interact with each other to jointly perform the"bone immune system,"which includes all cells in the bone marrow.Immuno-skeletal interface has protective effects on bone under physiological conditions,but it may lead to bone destruction under pathological conditions.Osteoprotegerin is mainly derived from B cells and can inhibit osteoclast metabolism.However,when the body is in an inflammatory state,T cells and B cells work together to promote bone resorption.In addition,interleukin-1,interleukin-6 and tumor necrosis factor-α regulate the expression of receptor activator of nuclear factor-κB ligand in vivo and affect bone metabolism.In most clinical diseases(such as rheumatoid arthritis,estrogen deficiency,HIV infection,and hyperparathyroidism),the immuno-skeletal interface interacts with the bone immune system,resulting in the regulation of bone metabolism.In terms of clinical prospect,the interaction between bone immunity and bone metabolism should be studied in order to propose new strategies for therapeutic intervention to reduce the risk of fracture.
