OBJECTIVE: To explore the correlation between the Barthel index score and other factors with the preoperative occurrence of deep vein thrombosis (DVT) in patients undergoing total hip arthroplasty (THA) revision surgery. METHODS: A retrospective analysis was conducted on clinical data from 122 patients who met the inclusion criteria and underwent THA revision surgery between April 2017 and November 2020. Among them, 61 were male and 61 were female, with an age range of 32-85 years (mean, 65.3 years). The reasons for revision included prosthetic joint infection in 7 cases, periprosthetic fracture in 4 cases, prosthetic dislocation in 6 cases, and aseptic loosening in 105 cases. The Barthel index score was 76.4±17.7, with 10 cases classified as level 1, 57 as level 2, 37 as level 3, and 18 as level 4. Univariate analysis was performed on variables such as age, gender, body mass index, Barthel index score, preoperative D-dimer positivity, history of diabetes, hypertension, cancer, cerebral infarction, smoking, and thrombosis in patients with and without preoperative DVT. Furthermore, logistic regression was used to identify risk factors for preoperative DVT in THA revision surgery. The incidence of preoperative DVT was compared among different Barthel index score groups. RESULTS: Preoperative DVT was detected in 11 patients (9.02%), all of whom had intermuscular venous thrombosis. Among them, 1 had prosthetic joint infection, 1 had periprosthetic fracture, 1 had prosthetic dislocation, and 8 had aseptic loosening. Univariate analysis showed significant differences between the two groups in terms of age, gender, and Barthel index score ( P<0.05). logistic regression further revealed that female, age ≥70 years, and Barthel index score<60 were independent risk factors for preoperative DVT in patients undergoing THA revision surgery ( P<0.05). The incidence of preoperative DVT in patients with Barthel index scores of levels 1, 2, 3, and 4 were 0 case (0%), 2 cases (3.5%), 3 cases (8.1%), and 6 cases (33.3%), respectively. A significant correlation was found between Barthel index score classification and the incidence of preoperative DVT in patients undergoing THA revision surgery ( χ ²=10.843， P=0.001). CONCLUSION In patients undergoing THA revision surgery, older age, female, and lower Barthel index scores are associated with higher preoperative DVT incidence. For patients with low preoperative Barthel index scores, preoperative thrombosis screening should be emphasized.

Pyroptosis is a new type of programmed cell death that can efficiently enhance the immune response by inducing cell lysis and inflammation, thereby facilitating tumor immunotherapy. Recently, an increasing number of studies have revealed close relationships between pyroptosis and nanomedicine, which has been regarded as a new strategy for developing nanomedicine-based immunotherapy for highly effective therapy of various cancers. In this review, the development and associated signaling pathways for pyroptosis, including the correlation between pyroptosis and anti-tumor immunity, were first presented. Then, various nanomedicines that induce pyroptosis for tumor therapy, especially immunotherapy, were systematically discussed. Finally, the current challenges and constructive perspectives in this field were proposed.

Atopic dermatitis (AD) is a common chronic inflammatory skin disorder affecting all age groups, especially children, with a prevalence of up to 20% globally. AD remains burdensome and incurable with current therapeutic strategies-ranging from trigger avoidance and skincare to medication-primarily address symptoms rather than disease modification, underscoring the imperative for innovative therapeutic paradigms. RNA-targeted therapies, particularly antisense molecules, have emerged as a transformative approach in precision medicine, with proven clinical success in diseases such as spinal muscular atrophy and familial chylomicronemia syndrome. These therapeutics achieve post-transcriptional regulation unattainable by conventional therapies, enabling direct targeting of messenger RNA (mRNA) and regulatory non-coding RNAs (ncRNAs) implicated in disease pathogenesis. Furthermore, skin is better suited to the antisense modulation due to the relatively easy access to target cells. Numerous studies have explored antisense-based targeting of key drivers in AD progression, yielding promising proof-of-concept results and prompting several early-stage clinical trials. This modality represents a paradigm shift in AD management-one that aligns with the broader revolution in RNA therapeutics reshaping modern medicine. This review critically examines the evolving role of antisense technology in AD, addressing both its mechanistic rationale and the translational challenges that must be overcome to realize its full clinical potential.

Objective:To evaluate the efficacy and safety of rituximab in pediatric myasthenia gravis (MG).Methods:Case series study. The clinical manifestations, laboratory tests, treatment plans and prognosis of 27 pediatric MG patients treated with rituximab from June 2013 to June 2023 at Children′s Medical Center of Peking University First Hospital were retrospectively collected.Results:There were 5 males and 22 females in 27 MG children. The onset age was 2.1 (1.6, 4.8) years, ranging from 8 months to 11 years. The clinical classification included 20 children (74%) of ocular MG and 7 children (26%) of generalized MG. Seventeen children (63%) had positive MG-related pathogenic antibodies, including 17 children of anti-AchR antibody and 1 of them also had anti-MuSK antibody. Rituximab was used as first-line immunosuppressant in 13 children, second-line immunosuppressant in 13 children and third-line immunosuppressant in 1 child. Immunosuppressants used before rituximab including 8 children of cyclosporine, 3 children of tacrolimus, 1 child of azathioprine, 1 child of mycophenolate mofetil and 1 child of cyclosporine combined with azathioprine. Rituximab was used for at least half a year with a follow-up period of more than 12 months. At the last follow-up after rituximab treatment, all children achieved improved or above, 14 children (52%) achieved complete stable remission, 7 children (26%) achieved pharmacologic remission, 1 child (4%) achieved minimal manifestations, and 5 children (18%) improved. After rituximab treatment, 27 children all could reduce the immunomodulation therapy and shorten the course of glucocorticoid therapy, and 22 children (81%) had stopped the glucocorticoid therapy. Among the 14 children with poor efficacy of other immunosuppressants, rituximab had complete stable remission of 7 children. The most common adverse reaction was respiratory infection (4 children (15%)). Only 2 children had allergic reaction to rituximab and got better after symptomatic treatment.Conclusions:Rituximab has good efficacy and tolerance in pediatric MG. Early application of rituximab can improve the prognosis and shorten the course of glucocorticoid treatment.

Objective:To explore the impact of early postoperative hypocaloric parenteral nutrition on perioperative infectious complications in patients undergoing hepatectomy for primary hepatic carcinoma.Methods:The data of 205 patients who underwent hepatectomy for primary hepatic carcinoma in the Division of Hepatobiliary and Transplantation Surgery at Nanjing Drum Tower Hospital between February 2020 and December 2022 were collected by a single center prospective cohort study. The patients were divided into a hypocaloric group ( n=108) and a normal calorie group ( n=97) based on whether they received hypocaloric parenteral nutrition within 72 hours postoperatively. The influence of early parenteral nutrition caloric on perioperative infectious complications was analyzed. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s) and compared using t-test. Measurement data with skewed distribution were expressed as M( Q1, Q3) and compared using the Wilcoxon rank-sum test. Comparison of categorical data was performed using the chi-square test or Fisher′s exact test. To adjust for confounding factors, patients were grouped for comparison based on whether they experienced infectious complications within the 30-day postoperative follow-up period. Factors that may influence postoperative infectious complications were first analyzed using univariate analysis, and variables with statistical significance were then included in multivariate analysis. Results:A total of 82 patients experiencing infectious complications, resulting in an incidence rate of 40.0%. Patients in the hypocaloric parenteral nutrition group had significantly lower rates of hyperglycemic events (17.6% vs 29.9%, P=0.038) and gastrointestinal reactions (12.0% vs 22.7%, P=0.043) compared to the normal calorie parenteral nutrition group, with no intergroup differences in other nutrition-related complications. Univariate analysis results revealed that hypocaloric parenteral nutrition, hepatocellular carcinoma, malnutrition assessed by the GLIM criteria, open surgery, major hepatectomy, perioperative hyperglycemic events, and the presence of pleural or ascitic fluid were potential influencing factors for the occurrence of infectious complications ( P<0.05). Multivariate analysis results suggested that malnutrition ( OR=2.707, 95% CI: 1.153-6.354, P=0.022), open surgery ( OR=2.103, 95% CI: 1.073-4.122, P=0.030), perioperative hyperglycemic events ( OR=2.630, 95% CI: 1.228-5.631, P=0.013), and the presence of pleural or ascitic fluid ( OR=2.714, 95% CI: 1.388-5.306, P=0.004) were risk factors for perioperative infectious complications in patients undergoing hepatectomy for primary hepatic carcinoma, while early postoperative hypocaloric parenteral nutrition ( OR=0.388, 95% CI: 0.199-0.757, P=0.006) was a protective factor. Conclusion:For patients undergoing hepatectomy for primary hepatic carcinoma, early postoperative hypocaloric parenteral nutrition may reduce the incidence of perioperative infectious complications compared to normal caloric parenteral nutrition, thereby improving patient clinical outcomes.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
