Objective To investigate the effect of indigo on inflammatory factors and the aryl hydrocarbon receptor(AhR)/NOD-like receptor thermal protein domain associated protein 3(NLRP3)signaling pathway in lipopolysaccharide(LPS)-induced keratinocytes(HaCaT cells).Methods An LPS-induced HaCaT cell model was established,and experimental groups were set as follows:blank group,model group,indigo group,AhR agonist(2,3,7,8-tetrachlorodibenzo-p-dioxin,TCDD)group,AhR inhibitor(CH-223191)group,and indigo+AhR inhibitor group.The Cell Counting Kit-8(CCK-8)assay was used to detect the effects of different concentrations of indigo,TCDD,and CH-223191 on HaCaT cell viability after 24 hours of intervention.Quantitative real-time PCR(qPCR)was employed to measure the mRNA expression levels of interleukin-1β(IL-1β),nuclear factor kappa B(NF-κB),tumor necrosis factor-α(TNF-α),AhR,cytochrome P450 family 1 subfamily A member 1(CYP1A1),NLRP3,Caspase-1,and apoptosis-associated speck-like protein(ASC)in each group.Western Blot analysis was used to assess changes in the cellular localization of AhR protein expression.Results(1)The IC50 of indigo intervention in HaCaT cells was 118.7 μmol·L-1.Treatment with different concentrations of CH-223191 and TCDD for 24 hours had no significant effect on HaCaT cell viability.(2)Compared with the model group,the indigo group showed decreased mRNA expression levels of IL-1β,NF-κB,NLRP3,and Caspase-1(P＜0.05 or P＜0.000 1),while the mRNA expression levels of AhR and CYP1A1 were significantly increased(P＜0.05 or P＜0.000 1).(3)Compared with the blank group,the indigo group reduced cytoplasmic AhR protein expression and increased nuclear AhR protein expression(P＜0.001 or P＜0.000 1).(4)Compared with the model group,both the indigo group and the AhR agonist group significantly increased AhR mRNA expression levels(P＜0.05),while the AhR inhibitor group decreased AhR and CYP1A1 mRNA expression levels(P＜0.05)and increased IL-1β and NLRP3 mRNA expression levels(P＜0.05).(5)Compared with the AhR inhibitor group,the indigo+AhR inhibitor group showed increased mRNA expression levels of AhR and CYP1A1(P＜0.05)and decreased mRNA expression levels of NLRP3,Caspase-1,and IL-1β(P＜0.05).Conclusion Indigo reduces inflammatory factors in LPS-induced HaCaT cells and participates in inhibiting the occurrence and development of psoriasis by activating AhR to negatively regulate the NLRP3 inflammasome.

Gestational diabetes mellitus(GDM)is closely associated with short-term and long-term adverse outcomes for both mothers and fetuses.In recent years,with the global prevalence of obesity and type 2 diabetes mellitus(T2DM)constantly rising,there is a significant increase in GDM incidence,with notable regional variations.Current challenges in GDM management include insufficient early screening or diagnosis,limited personalized intervention strategies,and poor adherence to long-term follow-up.Key research priorities for the future include optimizing screening methods for high-risk populations,enhancing targeted lifestyle interventions,and establishing effective follow-up and long-term health management systems.In December 2024,the American Diabetes Association(ADA)released the Standards of Care in Diabetes—2025(hereafter referred to as ADA[2025]),providing updated perspectives on the diagnosis and treatment of diabetes mellitus,as well as an overview of the definition,screening and diagnostic criteria,and management strategies for GDM.Based on ADA(2025)and the circumstances of clinical practice in China,we summarized the latest advancements in GDM research,aiming to improve comprehensive management strategies to prevent,delay,and improve adverse outcomes associated with GDM.

Simmering method is one of the traditional processing methods of Chinese materia medica， which has been documented in the herbal literature and medical books of the past dynasties and has a great variety， but at present， there are not many specific varieties of Chinese materia medica involved， and there are few related researches. By reviewing the ancient and modern related information， the authors have organized and analyzed the historical evolution， processing purpose， modern representative Chinese materia medica（processing technology， quality evaluation， pharmacological research） of simmering method. After sorting out， it was found that the simmering method was widely used in ancient times， which was first seen in Huashi Zhongzangjing of the Eastern Han dynasty， and was enriched and developed through the Tang， Song， Jin， Yuan， Ming and Qing dynasties， and entered its heyday in Ming and Qing dynasties along with the economic prosperity and development of the Ming dynasty， involving as many as 159 varieties of Chinese materia medica， and gradually perfecting the processing theory of the simmering method. However， the number of varieties that still use the simmering method in modern times significantly decreased. The main purposes of using simmering method in modern Chinese materia medica are to reduce adverse reactions， moderate medicinal properties， enhance therapeutic effects， remove non-medicinal parts， and facilitate further processing， etc. This paper combed the key information of simmering methods for Chinese materia medica from ancient to modern times， which can provide a literature basis for the clinical application and modern research of simmered products of Chinese materia medica.

Denosumab, a human monoclonal antibody, is used for the prevention of malignant tumor-related bone events and the treatment of osteoporosis with high fracture risk. Since its approval in China in 2019, denosumab-related osteonecrosis of the jaw (DRONJ) has attracted increasing attention. DRONJ, similar to bisphosphonate-related osteonecrosis of the jaw, often occurs after tooth extraction and manifests as exposed bone necrosis, purulent discharge, facial swelling and pain, severely impacting patients′ quality of life. However, the perioperative management strategies for DRONJ differ from those for bisphosphonate-related osteonecrosis of the jaw. This article summarizes the perioperative management strategies for high-risk DRONJ patients from aspects such as oral hygiene care, antibiotic use, drug discontinuation during the perioperative period, and surgical strategy selection, aiming to provide guidance for oral surgeons in managing tooth extraction in denosumab-treated patients.

The rational use of medical consumables in clinical practice is of great significance for improving medical quality and controlling medical costs. In June 2023, a tertiary hospital established a management organization system, formulated a list of key monitored medical consumables, built supporting information system and database, and established a warning mechanism, to explore the rationality evaluation path for clinical use of medical consumables through in-depth analysis of the entire hospital-department-disease-surgical procedure. This evaluation path achieved good results. Taking absorbable hemostatic gauze as an example, through implementing this evaluation path, problems with the clinical use of this consumable were promptly identified, and targeted improvements were made. After rectification, the number of absorbable hemostatic gauze used in the third quarter of 2023 (209.0 pieces) had decreased compared to the second quarter of the same year (254.0 pieces), and clinical use was more reasonable and standardized. This evaluation path achieved refined control over key monitored medical consumables, which could provide references for other hospitals to carry out the management of clinical rational use of medical consumables.

ObjectiveTo study the differences in volatile oil content of bran-processed Atractylodes lancea and its standard decoction concentrate and freeze-dried powder， as well as the differences in the types and contents of chemical components in volatile oil， and to clarify the quality value transmitting. MethodTen batches of A. lancea rhizoma were collected and prepared into raw products and bran-processed products of A. lancea， standard decoction concentrate and freeze-dried powder of bran-processed A. lancea in order to extract the volatile oil， and the transfer rate of volatile oil in each sample was calculated. Quantitative analysis of the main chemical components（β-eudesmol， atractylon， atractylodin） in each volatile oil was performed by gas chromatography（GC） on the HP-5 quartz capillary column（0.32 mm×30 m， 0.25 μm） with a flame ionization detector（FID）， a split ratio of 10∶1 and a temperature program（initial temperature at 80 ℃， hold for 1 min， rise to 150 ℃ at 10 ℃·min^-1， hold for 10 min， rise to 155 ℃ at 0.5 ℃·min^-1， hold for 5 min， rise to 240 ℃ at 8.5 ℃·min^-1， hold for 8 min）. Cluster analysis and principal component analysis（PCA） were used to explore the overall differences in types and contents of chemical components between the standard decoction concentrate and freeze-dried powder. ResultThe transfer rates of volatile oil in the bran-processed products， standard decoction concentrate and freeze-dried powder were 70.51%， 1.57% and 40.90%， respectively. The average transfer rates of β-eudesmol， atractylon and atractylodin in the volatile oil of bran-processed A. lancea were 58.45%， 48.49% and 55.64%， respectively. In the standard decoction concentrate， only β-eudesmol and atractylodin were detected， and their average transfer rates were 0.22% and 0.10%， respectively. And only β-eudesmol was detected in the freeze-dried powder with the average transfer rate of 8.37%. The results of cluster analysis and PCA showed that there are obvious differences in the types and contents of chemical components between the standard decoction concentrate and freeze-dried powder. ConclusionThe quality value transmitting between bran-processed A. lancea and its standard decoction concentrate and freeze-dried powder is stable， and if the freeze-dried powder is selected as the reference material of dispensing granules， appropriate amount of volatile oil should be added back to make it consistent with the quality of the standard decoction concentrate.

As a novel and promising antitumor target, AXL plays an important role in tumor growth, metastasis, immunosuppression and drug resistance of various malignancies, which has attracted extensive research interest in recent years. In this study, by employing the structure-based drug design and bioisosterism strategies, we designed and synthesized in total 54 novel AXL inhibitors featuring a fused-pyrazolone carboxamide scaffold, of which up to 20 compounds exhibited excellent AXL kinase and BaF3/TEL-AXL cell viability inhibitions. Notably, compound 59 showed a desirable AXL kinase inhibitory activity (IC₅₀: 3.5 nmol/L) as well as good kinase selectivity, and it effectively blocked the cellular AXL signaling. In turn, compound 59 could potently inhibit BaF3/TEL-AXL cell viability (IC₅₀: 1.5 nmol/L) and significantly suppress GAS6/AXL-mediated cancer cell invasion, migration and wound healing at the nanomolar level. More importantly, compound 59 oral administration showed good pharmacokinetic profile and in vivo antitumor efficiency, in which we observed significant AXL phosphorylation suppression, and its antitumor efficacy at 20 mg/kg (qd) was comparable to that of BGB324 at 50 mg/kg (bid), the most advanced AXL inhibitor. Taken together, this work provided a valuable lead compound as a potential AXL inhibitor for the further antitumor drug development.
