Objective: To explore the independent risk factors of allogeneic blood transfusion during perioperative period of cytoreductive surgery in patients with ovarian cancer, and to construct a predictive model to facilitate clinical risk assessment and optimize perioperative blood management. Methods: Clinical data of 156 patients who underwent cytoreductive surgery for ovarian cancer in our hospital from January 2020 to December 2025 were retrospectively collected. The patients were divided into transfusion group (n=51) and non-transfusion group (n=105) according to whether they received allogeneic blood transfusion during perioperative period. The 1∶1 propensity score matching (PSM) was used to correct the confounding factors. Independent sample t test or Mann-Whitney U test was used for measurement data, and chisquare test was used for enumeration data. Variables with P<0.05 in univariate analysis were included in binary logistic regression for multivariate analysis to determine independent risk factors. A nomogram model for perioperative allogeneic blood transfusion risk prediction was constructed based on independent risk factors. Bootstrap method (100 samples) was used for internal calibration verification. ROC curve was used to evaluate the discrimination efficiency, and decision curve analysis (DCA) was used to evaluate the clinical net benefit of the model. Results: After propensity matching, the baseline data of the two groups were balanced and comparable. Multivariate logistic regression analysis showed that preoperative prothrombin time (PT) (OR=2.666, 95%CI 1.249~5.693, P=0.011), preoperative hemoglobin (Hb) (OR=0.953, 95%CI 0.923~0.984, P=0.003), intraoperative blood loss (OR=1.004, 95%CI 1.001-1.006, P=0.004), preoperative anemia grade (OR=3.052, 95%CI 1.007-9.252, P=0.049) were independent influencing factors of perioperative allogeneic blood transfusion. The nomogram model based on the above four factors was significant (LR χ =58.617, P<0.001), and the internal calibration curve showed that the predicted probability of the model was in good agreement with the actual probability (mean absolute error=0.042). The area under the ROC curve (AUC) was 0.890, indicating good discrimination efficiency. DCA showed that the clinical net benefit of the model was better than that of the unified transfusion/non-transfusion strategy in the 0-0.45 risk threshold range. Conclusion: Intraoperative blood loss, preoperative PT, preoperative Hb and preoperative anemia grade are independent risk factors for perioperative allogeneic blood transfusion in patients undergoing cytoreductive surgery for ovarian cancer. The nomogram model based on the above factors has good predictive efficacy and clinical hierarchical decision-making value, which can provide reference for clinical implementation of individualized blood management for high-risk patients and reduction of unnecessary blood transfusion rate.

ObjectiveTo explore the possible mechanism of action of Lifei Xiaoji Pill （理肺消积丸， LXP） in the treatment of non small cell lung cancer based on the Warburg effect and the USP47/BACH1 pathway. MethodsFifty C57BL/6 mice were randomly divided into five groups， model group， LXP group， inhibitor group， LXP + inhibitor group， and cisplatin group， with 10 mice in each group. A lung cancer mouse model was established by subcutaneously injecting Lewis cells. On the next day， the model group mice were given 0.2 ml of saline by gavage daily， the LXP group given 240 mg/（kg·d） of LXP solution once a day by gavage， the inhibitor group intraperitoneally injected with P22077 at a dose of 10 mg/（kg·d） every day， the LXP + inhibitor group given both LXP by gavage and P22077 by intraperitoneal injection once a day， and the cisplatin group received 0.5 mg/（kg·d） cisplatin intraperitoneally every other day. All treatments lasted for 14 days. On the day after the last dose， tumor weight and volume were measured， tumor histopathology was examined by HE staining， apoptosis in tumor tissues was detected by TUNEL staining， and proliferation cell nuclear antigen （PCNA） protein levels were detected by immunohistochemistry. Warburg effect indicators， including glucose concentration， lactate content， and adenosine triphosphate （ATP） production in tumor tissues， were measured. Western Blot and qRT-PCR were used to detect the protein and mRNA expression levels of USP47， BACH1， hexokinase 2 （HK2）， and glyceraldehyde 3-phosphate dehydrogenase （GAPDH）. ResultsCompared with the model group， all drug intervention groups showed reduced tumor weight and volume， improved tumor pathology， decreased PCNA positive rate， increased apoptosis rate， and reduced expression levels of USP47， BACH1， and HK2 proteins and mRNA （P＜0.05 or P＜0.01）. Except for lactate content in the cisplatin group， the glucose concentration in tumor tissues of other drug intervention groups increased， while lactate content and ATP production decreased （P＜0.05 or P＜0.01）. Compared with the LXP group， the LXP + inhibitor group showed more significant improvements in these indicators （P＜0.05 or P＜0.01）. Compared with the cisplatin group， the LXP + inhibitor group had lower mRNA expression of HK2 and GAPDH， and lower protein levels of USP47 and HK2 （P＜0.05 or P＜0.01）. Compared with the inhibitor group， the cisplatin group had higher HK2 protein levels， while the LXP + inhibitor group showed lower mRNA expression of BACH1， HK2， and GAPDH （P＜0.05 or P＜0.01）. ConclusionLXP significantly inhibits tumor growth in lung cancer mice， and its mechanism of action may be related to inhibiting the Warburg effect via the USP47/BACH1 pathway.

Thyroid-associated ophthalmopathy (TAO) is the ocular manifestation of thyroid autoimmune dysfunction.Its clinical feathers mainly include eyelid retraction, proptosis, and ocular movement disorders.TAO is the most common orbital diseases.The pathogenesis of TAO has not been fully elucidated, but researchers generally believe that T cells play an important role in the pathogenesis of TAO.In the early stage of TAO development, a large number of T cells are activated and infiltrated into the retroorbital soft tissue.T cells can be divided into CD4 + T cells and CD8 + T cells.CD4 + T cells play a more central role in TAO.CD4 + T cells include Th1, Th2, Treg and recently discovered Th17, Th22 and Tfh cells.In target tissues, the complete activation and later function of T cells largely rely on the costimulatory pathways, there needs to unravel the mechanism of these costimulatory pathways in TAO.This paper reviews the recent research progress of T cells and costimulatory signals required for their activation in the pathogenesis of TAO.

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.
