The abnormal accumulation of neutrophil extracellular traps （NETs） can promote the initiation and progression of pancreatic cancer， which is considered a potential therapeutic target for this disease. The Miraculous Pivot·Inquiry About Statement （《灵枢·口问》） have recorded the concept of "defensive qi stagnation". Based on the recognition that the function of defensive qi is similar to the immune function of neutrophils， and combining traditional Chinese medicine theory with clinical practice， it is proposed that the abnormal accumulation of NETs may be a pathological product of "defensive qi stagnation"， with the spleen being the critical site of pathology. Further exploring the application strategy of cleaning spleen and restoring defensive qi method in pancreatic cancer treatment， it is proposed to employ three approaches such as dredging method to eliminate spleen stagnation and inhibit pancreatic cancer proliferation， cleaning method to remove spleen dampness and suppress the inflammatory micro-environment， and tonifying method to strengthen Weiqi and to improve the immune microenvironment， which aims to provide new insights for the clinical treatment of pancreatic cancer with traditional Chinese medicine.

Objective To study the changes of lipid peroxidation and antioxidant capacity in patients with hypercholesterolemia.Methods A total of 100 patients with elevated cholesterol treated in the People's Hospital of Qitaihe from January to May 2024 were included in hypercholesterolemia group,and another 80 people with normal blood lipid in the hospital during the same period were included in control group.Malondialdehyde(MDA),glutathione(GSH),glutathione reductase(GR)and total antioxidant capacity(TAC)were determined in all subjects.Results The levels of total cholesterol,low density lipoprotein-cholesterol and MDA in hypercholesterolemia group were significantly higher than those in control group,while the levels of GSH,GR and TAC were significantly lower than those in control group(P＜0.05).Conclusion Patients with hypercholesterolemia have severe lipid peroxidation,which may cause vascular endothelial cell damage.

Objective:To analyze research trends, hotspots, and international collaboration in temporomandibular disorders (TMD) from 2010 to 2024 using bibliometric methods.Methods:A total of 4 368 articles published between January 2010 to December 2024 were retrieved from PubMed using the search strategy temporomandibular disorders[MeSH Terms] OR temporomandibular joint disorders[Title/Abstract]. The R package"bibliometrix" was employed to analyze publication statistics, author collaboration networks, and keyword co-occurrence.Results:The annual publication volume in the TMD field increased 3.4-fold from 2010 to 2024, with an average annual output of 291.2 articles. MANFREDINI DANIELE was identified as the most prolific author (74 articles). The Journal of Oral Rehabilitation ranked first in terms of publication quantity (454 articles). The University of S?o Paulo (Brazil) emerged as the leading contributor, followed by Sichuan University (China) globally. Research hotspots predominantly focused on the DC/TMD diagnostic criteria and pain mechanisms. Analysis of international collaboration networks revealed that core authors (e.g., Lobbezoo F, Manfredini D) have driven advancements in the field through multidisciplinary collaboration (dentistry+psychology+medical imaging). The high-frequency occurrence of the imaging keyword "magnetic resonance imaging (MRI)" underscores its pivotal role in diagnosing disc displacement. Chinese institutions (Sichuan University, Peking University) ranked second globally in research output; however, interdisciplinary international collaboration remained limited, with multiple-country publications (MCP) accounting for only 13.0%. Conclusions:TMD research demonstrates interdisciplinary integration, highlighting the need for future emphasis on Asian population studies and innovative diagnostic/therapeutic technologies.

Objective:To summarize the clinical and related characteristics of hospitalized patients with pemphigus, and to analyze their correlations with systemic inflammatory and serological indicators.Methods:A retrospective analysis was conducted on the clinical data from pemphigus patients hospitalized in the Department of Dermatology, Wuhan No.1 Hospital from January 2021 to December 2023. Spearman correlation analysis was performed to assess the correlations between the Pemphigus Disease Area Index (PDAI) scores and systemic immune-inflammation index (SII) , pan-immune-inflammation value (PIV) , serum albumin levels, anti-desmoglein 1/3 (Dsg-1/3) antibody levels, and C-reactive protein (CRP) levels. Linear regression models were used to evaluate the associations of systemic inflammatory and serological indicators with the length of hospital stay and treatment costs. Logistic regression analysis was conducted to analyze the effect of these indicators on the risk of infection in pemphigus patients.Results:A total of 235 pemphigus patients were included (112 males and 123 females) , with ages of 58.12 ± 16.47 years. Among them, 73 patients (31.06%) had pemphigus alone, while 162 (68.94%) had comorbidities including tumors, infections, or hypoalbuminemia. PDAI scores showed significantly positive correlations with SII, PIV, and CRP levels ( r = 0.62, 0.58, 0.50, respectively, all P<0.001) . According to PDAI scores, 164 cases (69.79%) were classified as mild pemphigus, 57 (24.26%) as moderate pemphigus, and 14 (5.96%) as severe pemphigus; compared with the patients with mild pemphigus, those with moderate-to-severe pemphigus had significantly increased SII, PIV, anti-Dsg-1 antibody and CRP levels, but significantly decreased serum albumin levels (all P < 0.05) . Among the 235 patients, 213 were diagnosed with pemphigus vulgaris, 9 with pemphigus erythematosus, 10 with pemphigus foliaceus, and 3 with paraneoplastic pemphigus; serum albumin levels and anti-Dsg-1/3 antibody levels differed significantly among patients with different subtypes of pemphigus (all P < 0.05) . The serum albumin level was significantly associated with the length of hospital stay and treatment costs ( β [95% CI]: -0.729 [-0.946 - -0.512], -0.266 [-0.362 - -0.171], respectively, both P < 0.001) ; furthermore, the serum albumin level was identified as a relevant factor for infections in pemphigus patients ( OR = 0.938, 95% CI: 0.883 - 0.995, P = 0.036) . Conclusion:SII, PIV, CRP, serum albumin, and anti-Dsg-1 antibody levels could reflect the severity of pemphigus to some extent, and the serum albumin level was significantly associated with comorbid infections, length of hospital stay, and treatment costs in hospitalized patients with pemphigus.
