Purpose: Since 1995, the Korean Gastric Cancer Association (KGCA) has been periodically conducting nationwide surveys on patients with surgically treated gastric cancer. This study details the results of the survey conducted in 2023. Materials and Methods: The survey was conducted from March to December 2024 using a standardized case report form. Data were collected on 86 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. The results of the 2023 survey were compared with those of previous surveys. Results: Data from 12,751 cases were collected from 66 institutions. The mean patient age was 64.6 years, and the proportion of patients aged ≥71 years increased from 9.1% in 1995 to 31.7% in 2023. The proportion of upper-third tumors slightly decreased to 16.8% compared to 20.9% in 2019. Early gastric cancer accounted for 63.1% of cases in 2023.Regarding operative procedures, a totally laparoscopic approach was most frequently applied (63.2%) in 2023, while robotic gastrectomy steadily increased to 9.5% from 2.1% in 2014.The most common anastomotic method was the Billroth II procedure (48.8%) after distal gastrectomy and double-tract reconstruction (51.9%) after proximal gastrectomy in 2023.However, the proportion of esophago-gastrostomy with anti-reflux procedures increased to 30.9%. The rates of post-operative mortality and overall complications were 1.0% and 15.3%, respectively. Conclusions The results of the 2023 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for future gastric cancer research.

OBJECTIVE: To observe the clinical efficacy of Fu's subcutaneous needling based on "multi-joint muscle spiral balance chain" theory for cervical vertigo (CV) and its effect on blood flow velocity of vertebral artery. METHODS: A total of 60 patients with CV were randomized into a Fu's subcutaneous needling group and a medication group, 30 cases in each one. In the Fu's subcutaneous needling group, Fu's subcutaneous needling was delivered at Dazhui (GV14), the flexible tube was retained for 5 min after sweeping manipulation, and the treatment was given once every other day, 3 times a week for 3 weeks. In the medication group, betahistine mesylate tablet and diclofenac sodium dual-release enteric capsule were taken orally for continuous 3 weeks. Before treatment, after treatment, and in follow-up of one month after treatment completion, the scores of dizziness handicap inventory (DHI) and visual analogue scale (VAS) were observed; before and after treatment, the blood flow velocity of vertebral artery was measured by transcranial Doppler, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment and in follow-up, each item scores and total scores of DHI were decreased compared with those before treatment in the two groups (P<0.05); the VAS scores after treatment in the two groups, as well as the VAS score in follow-up of the Fu's subcutaneous needling group, were decreased compared with those before treatment (P<0.05). In the Fu's subcutaneous needling group, after treatment and in follow-up, the physical scores and the total scores of DHI, and the VAS scores were lower than those in the medication group (P<0.05); in follow-up, the emotional and functional scores of DHI were lower than those in the medication group (P<0.05). After treatment, the mean blood flow velocity (Vm) of the left vertebral artery (LVA) and the right vertebral artery (RVA) was increased compared with that before treatment in the two groups (P<0.05), and the Vm of LVA and RVA in the Fu's subcutaneous needling group was higher than that in the medication group (P<0.05). The total effective rate was 100.0% (30/30) in the Fu's subcutaneous needling group, which was superior to 73.3% (22/30) in the medication group (P<0.05). CONCLUSION Fu's subcutaneous needling based on the "multi-joint muscle spiral balance chain" theory can effectively alleviate the vertigo and neck pain, and improve the blood flow velocity of vertebral artery in CV patients, and has a long-term therapeutic effect.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

ObjectiveTo explore the mechanism of Cangxi Tongbi capsules （CXTB） in regulating the p38 mitogen-activated protein kinase （p38 MAPK）/NOD-like receptor protein 3 （NLRP3）/cysteine protease-1 （Caspase-1） signaling pathway to inhibit pyroptosis of cartilage cells in knee osteoarthritis （KOA）. MethodSixty male SD rats were randomly divided into a sham operation group， a model group， low， medium， and high dose CXTB groups， and a positive control group， with 10 rats per group. The modified Hulth method was employed to establish a rat model of KOA. According to their respective assignments， rats were administered CXTB （0.25， 0.5， 1.0 g·kg^-1） and Celecoxib （24 mg·kg^-1） by gavage. The sham operation and model groups were given an equivalent volume of physiological saline. Treatment was performed once daily for 28 days. Micro-computed tomography （Micro-CT） was used to assess bone volume/total volume （BV/TV） and trabecular separation （Tb.Sp）. Joint degeneration was evaluated through hematoxylin-eosin （HE） staining， safranin-fast green （SO） staining， and Osteoarthritis Research Society International （OARSI） scoring. Western blot analysis was conducted to measure the expression levels of p38 MAPK， phosphorylated p38 MAPK （p-p38 MAPK）， NLRP3， Caspase-1， and gasdermin D （GSDMD） proteins. Real-time PCR was used to assess mRNA expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD genes. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum concentrations of inflammatory cytokines including tumor necrosis factor-alpha （TNF-α）， interleukin-1 beta （IL-1β）， and interleukin-18 （IL-18）. After knee replacement surgery， cartilage tissue was analyzed using Western blot to assess the protein expression levels of p38 MAPK， p-p38 MAPK， NLRP3， Caspase-1， and GSDMD， and Real-time PCR was used to evaluate gene expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD. ResultMicro-CT analysis revealed significant narrowing of the joint space and increased bone spur formation in KOA rats compared with the sham operation group， with a decrease in BV/TV ratio and an increase in Tb.Sp value （P<0.01）. Serum levels of TNF-α， IL-1β， and IL-18 were elevated （P<0.01）. The protein expression levels of p-p38 MAPK， NLRP3， Caspase-1， and GSDMD in cartilage were significantly increased （P<0.01）， and the mRNA expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD were also enhanced （P<0.01）. Significant differences in protein expression of p-p38 MAPK， NLRP3， Caspase-1， and GSDMD were observed between normal and diseased cartilage tissues after knee replacement surgery （P<0.05）， and the gene expression of p38 MAPK， NLRP3， Caspase-1， and GSDMD were also significantly different （P<0.01）. HE and SO staining showed roughened joint surfaces， reduced cartilage thickness， and disordered cellular arrangement in KOA rats. OARSI scores were significantly higher （P<0.01）. Compared with the model group， treatment with low， medium， and high concentrations of CXTB resulted in increased BV/TV ratios and decreased Tb.Sp values in the knee joints of rats （P<0.01）. HE and SO staining indicated a trend towards smoother joint surfaces and reduced OARSI scores （P<0.01）. The protein expression levels of p-p38 MAPK， NLRP3， Caspase-1， and GSDMD were notably decreased （P<0.05）， as were the mRNA expression levels of p38 MAPK， NLRP3， Caspase-1， and GSDMD （P<0.01）. Additionally， serum concentrations of TNF-α， IL-1β， and IL-18 were significantly reduced （P<0.01）. ConclusionCXTB intervention may alleviate knee joint degeneration in KOA rats and inhibit the expression of inflammatory factors and pyroptosis of cartilage cells， thereby protecting cartilage. The underlying mechanism may involve modulation of the p38 MAPK/NLRP3/Caspase-1 signaling pathway.
