Plants of the Isodon genus are an important source of terpenoids， with their constituents exhibiting rich structural diversity and remarkable biological activities （such as anticancer， antimicrobial， and anti-inflammatory properties）， demonstrating significant potential in the field of immunomodulation. This review summarizes recent advances in the immunomodulatory mechanisms， development and application of terpenoid compounds from the Isodon genus. It has been found that these compounds can modulate key inflammatory signaling pathways， such as nuclear factor-kappa B （NF-κB） and mitogen-activated protein kinases （MAPKs）， thereby blocking the cascade amplification of inflammatory factors， alleviating chronic inflammatory responses， and correcting immune dysregulation. Additionally， they can influence the polarization direction of macrophages and dynamically regulate the balance among different functional subsets of T cells， restoring immune homeostasis. Their clinical translation faces multiple challenges， including poor druggability， a lack of systematic safety data， the absence of precise pharmacodynamic biomarkers， complexities in clinical trial design， and unclear industrialization pathways.

Objective To analyze the correlation between inflammation,nutritional indicators and hy-poproteinemia in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Meth-ods The clinical data of patients with AECOPD admitted to the Department of Respiratory and Critical Care Medicine of the First Affiliated Hospital of Xiamen University from January 2020 to September 2022 were ret-rospectively analyzed,and the patients were divided into the hypoproteinemia group(n=73)and the non-hy-poproteinemia group(n=141)according to whether the serum albumin(ALB)was lower than 35 g/L.The clinical data,inflammatory indicators and nutritional indicators of the two groups were compared,Spearman correlation analysis was performed,and binary logistic regression analysis was performed to analyze the influ-encing factors of patients with AECOPD complicated with hypoproteinemia.Results There were statistically significant differences in age,length of hospital stay,and body weight between the two groups(P＜0.05).There were no significant differences in gender,number of hospitalizations in the past 1 year,height,diabetes,hypertension and proportion of coronary heart disease(P＞0.05).Compared with the non-hypoproteinemia group,the hypoproteinemia group had longer hospital stays and higher levels of C-reactive protein,neutrophil/albumin ratio(NAR),neutrophil to lymphocyte ratio(NLR),platelet-lymphocyte ratio(PLR),and systemic immunoinflammatory index(SII).The prognostic nutritional index(PNI),body mass index(BMI),hemoglo-bin and total protein levels were lower,and the difference was statistically significant(P＜0.05).Body weight,BMI,hemoglobin,total protein,PNI and AECOPD patients with hypoproteinemia were negatively cor-related(P＜0.05),while age,length of hospital stay,C-reactive protein,NAR,NLR,PLR,SII and AECOPD patients with hypoproteinemia were positively correlated(P＜0.05).Binary logistic regression analysis showed that PNI,SII and NLR were the influencing factors of hypoproteinemia in AECOPD patients.Conclusion In clinical practice,attention should be paid to and timely correction of hypoproteinemia in pa-tients with AECOPD,improvement of inflammatory indicators and nutritional status of patients,and preven-tion of acute exacerbation.

Cartilage tissue engineering offers a promising therapeutic approach for auricular, tracheal, and joint reconstruction. However, implanted engineered cartilage currently faces challenges such as host immune rejection and inflammatory reactions, which can lead to deformities and fibrosis, compromising long-term maintenance of shape and function. Effectively modulating immune and inflammatory responses is crucial for advancing the clinical application of engineered cartilage. This article reviewed relevant literature to analyze the mechanisms of inflammatory responses occurring after the implantation of tissue-engineered cartilage, and summarized the types and surface characteristics of biomaterials, providing a reference for the design of biomaterials in cartilage tissue engineering.

Objective:To investigate the early and mid-term outcomes of aortic endovascular remodeling device (AERD) for Stanford type A aortic dissection (TAAD) in type Ⅱhybrid surgery, and to evaluate its clinical efficacy.Methods:46 patients with TAAD, including 14 females and 32 males, participated in the single-center clinical trial of West China Hospital of Sichuan University and underwent type II hybrid surgery (Bentall / ascending aorta replacement + AERD implantation) from February 2021 to October 2023. The safety and efficacy of AERD in type Ⅱ hybrid surgery for TAAD were estimated by clinical indicators (postoperative mortality, cardiovascular and cerebrovascular accidents, paraplegia, ischemia), and blood flow condition (volume of the true and false lumen, and suprachial branches).Results:Three patients (6.52%) died during the follow-up period, and the operation-related mortality was 4.35% (2/46). The remaining 43 patients were followed up for an average of (25.53±9.60) months. There were two cases (4.35%) of stroke after the operation, and paraplegia, acute renal insufficiency, and other severe complications were not noticed. The blood flow of the superior branch of the aortic arch was unobstructed, and there was no significant difference in the blood flow of the branch before the operation and at each follow-up time point. Compared to the pre-operation, the true lumen volume of the stent part increased by 59.0% and the false lumen volume decreased by 82.4%.Conclusion:AERD is a safe and effective alternative in type II hybrid surgery for acute TAAD, which is helpful in improving perioperative and short- and long-term survival rates and clinical outcomes.

Objective:To analyzed the 3-year follow-up results in a single center to evaluate the mid-term clinical efficacy of aortic endovascular remodeling device(AERD).Methods:From January 2019 to June 2019, 18 patients with residual aortic dissection after proximal repair of acute aortic dissection were treated with AERD in our heart center of West China Hospital of Sichuan University. They were followed up for 3 years after surgery and underwent vascular enhanced CT review. The primary outcome of our study included all-cause mortality and stent-related mortality. Secondary outcome included branch patency rate, reoperation rate and the incidence of serious adverse events. Morphological measures assessed the effectiveness of AERD in treating residual distal dissection.Results:17 patients completed the 3-year follow-up, and 1 was lost to follow-up. There was no stent-related death, branch artery occlusion, or new serious adverse events. 12 patients completed vascular enhanced CT review, the true lumen was significantly expanded and the false lumen was reduced considerably at 3-year follow-up, true lumen volume, (52.39±22.32)cm 3 vs. (74.34±14.64) cm 3( P<0.01), false lumen volume(50.42±25.44) cm 3 vs. (32.32±31.75)cm 3( P<0.01). Increased true lumen diameter and area ( P<0.001) and decreased false lumen diameter( P<0.001) were significantly different from those before operation, especially in the level below the renal artery and 5 cm below the renal artery. Conclusion:The mid-term effect of AERD in treating distal residual dissection is satisfactory, and it promoted positive distal aorta remodeling with safety and effectiveness.

OBJECTIVE: To report on the clinical characteristics of a family of short-rib polydactyly syndrome type III and its pathogenic variants. METHODS: Muscle samples from the the third fetus was collected after the induction of labor, and peripheral blood samples of its parents and grandparents were also collected. Whole exome sequencing (WES) was carried out for the pedigree. Candidate variants were verified by Sanger sequencing of the family. RESULTS: The proband was found to harbor a c.9819+1G>A variant and a c.4625C>A variant of the DYNC2H1 gene, which were respectively inherited from its mother and father. Sanger sequencing verified that the family has fit the autosomal recessive inheritance. CONCLUSION The c.9819+1G>A and c.4625C>A variants of the DYNC2H1 gene probably underlay the short-rib polydactyly syndrome type 3 in the proband.

As for the treatment of microtia, the status quo is as follows. The ear reconstruction with autologous costal cartilage has been generally accepted as the therapeutic strategy for type Ⅲ/Ⅳ patients with only small ear lobe remaining or complete absence of auricle, and the outcomes are improved steadily with the advances in technology; but for type Ⅰ/Ⅱ patients with larger remnant ear, there is insufficient evidence to be able to support any specific treatment methods as the potential unified approach for surgeons to choose from. Non-surgical treatment with appliance wearing may play an auxiliary role in the treatment of microtia, which is worthy of further research. The authors proposed a serialized treatment system based on their clinical practice and literature review. It is expected to be helpful for the treatment of microtia.

Autologous costal cartilage is the best material for auricle reconstruction due to its superior biomechanical properties and histocompatibility. However, costal cartilage harvest inevitably lead to the damage of the donor site. By conducting a comprehensive search for relevant literatures, the authors reviewed the donor site complications of autologous costal cartilage ear reconstruction, including thoracic deformity, pneumothorax, scar and pain, as well as the corresponding prevention and treatment methods, hoping to provide reference for the clinical application of autologous costal cartilage ear reconstruction.
