ObjectiveTo assess the predictive value of the bladder deformation index (BDI) in determining upper urinary tract (UUT) damage among patients with neurogenic bladder (NB). MethodsClinical data of 132 NB patients admitted to Beijing Bo'ai Hospital from January, 2015 to December, 2018 were retrospectively analyzed. Patients were divided into UUT damage group and normal UUT group according to the presence or absence of hydronephrosis. The demographics, biochemical parameters and video-urodynamics (VUDS) findings were collected, and BDI was calculated. Receiver operating characteristic (ROC) curves were utilized to evaluate the predictive capability. ResultsThere were 54 patients in UUT damage group and 33 in normal UUT group. The course of disease, creatinine level and BDI were siginificantly different between two groups (P < 0.05), while the area under the curve were 0.686, 0.836 and 0.928, respectively. ConclusionCourse of disease, creatinine level and BDI are associated with UUT damage in NB patients, and BDI demonstrates the highest sensitivity and specificity, which may play a role in diagnosis of UUT damage.

Objective:To investigate the influence of four preoperative CT image characteristics on the outcome of thoracoscopic surgery for chronic tuberculous empyema.Methods:This is a retrospective cohort study. Two hundred and eleven patients of tuberculous empyema who underwent video-assisted thoracic surgery(VATS) decortication at the First Department of Surgery , Wuhan Pulmonary Hospital from June 2020 to June 2023 were retrospectively analyzed. There were 162 male cases and 49 female cases, with an age ( M (IQR)) of 33 (27) years (range: 8 to 76 years). Patients were divided into two groups according to whether low-density lines, mass-patchy density, pleural fusion were observed, and the lesion size. Compare the clinical indicators of two groups of cases. Using the rapeutic efficacy as the dependent variable and four CT features as covariates, cases with cure or improve were included in Logistic regression analysis to calculate OR (95% CI) values. Results:Preoperative chest CT images showed that 127 cases (60.2%) had low-density lines, 102 cases (48.3%) had mass-patchy density, and 88 cases (47.7%) had pleural fusion. The lesions spanned 2 to 11 intercostal spaces, with a median of 7 intercostal spaces. The lesion size was divided into two groups according to <7 intercostal spaces and ≥7 intercostal spaces, with 101 cases (47.9%) and 110 cases (52.1%), respectively. In the intra-group comparison, there were no difference in age, lesion location and pulmonary tuberculosis. In the comparison of gender, except that the proportion of female patients in the group with lesion size <7 intercostal spaces ( χ2=6.064, P=0.010) was higher than ≥7 intercostal spaces, there were no significant difference between other groups. In low-density lines group, there was no difference in the incidence of anemia and hypoproteinemia between the two groups. Compared with the non low-density line group, patients with low-density line group exhibited fewer cases of abnormal elevation in ESR and CRP was lower(all P<0.01), the period of preoperative treatment ( U=7 281.00, P<0.01) was longer than the non low-density line group, while the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration, and therapeutic efficacy were all better than the non low-density line group(all P<0.05). In the comparison between the mass-patchy density group, there were fewer cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP in the without mass-patchy density group(all P<0.05), and the period of preoperative treatmentwas shorter ( U=4 581.50, P=0.026), and the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration and therapeutic effect were better too(all P<0.05). In the grouping comparison of pleural fusion, there were no difference in cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP, and the period of preoperative treatment between the two groups; the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours, postoperative drainage duration, lung re-expansion duration, and therapeutic efficacy of the group without pleural fusion were better than the group with pleural fusion(all P<0.05). The group with <7 intercostal spaces had fewer cases of anemia, hypoproteinemia, abnormal elevation of ESR and CRP (all P<0.05), the period of preoperative treatment was longer ( U=4 295.00, P=0.004), the operation time, intraoperative hemorrhage, postoperative drainage at 72 hours,postoperative drainage duration, lung re-expansion duration and complications were less (all P<0.05), the therapeutic efficacy was better than the group with ≥7 intercostal spaces ( χ2=27.912, P<0.01). The Logistic regression analysis of cured and improved cases showed that mass-patchy density and lesion size were independent risk factors affecting the therapeutic efficacy (all P<0.05). Conclusions:For patients with CT images showing mass-patchy density, pleural fusion, and a large lesion size, the difficulty and risk of surgery may be relatively high.The preoperative CT images can provide objective reference for clinical preoperative evaluation.

Isolated axillary recurrence(AR)after breast cancer surgery is one of the critical factors influencing patients'prognosis.With advancements in diagnostic and therapeutic techniques,the clinical understanding of AR has progressively deepened.However,due to the low incidence of AR,systematic studies on its clinical features remain limited.High-quality clinical trials,such as ACOSOG Z0011 and AMAROS,have demonstrated that in patients with varying statuses of sentinel lymph node,axillary lymph node dissection(ALND)and sentinel lymph node dissection(SLND)provide comparable control of AR.In recent years,the trend towards de-escalation axillary surgery has advanced the development of less invasive techniques such as targeted axillary lymph node dissection.The SOUND trial further confirmed the safety and feasibility of omitting axillary surgery in patients with tumors≤2 cm.In addition,a series of clinical studies have identified a variety of potential high-risk factors,including patient age,number of positive lymph nodes,high Ki-67 proliferation,extranodal extension,and axillary soft tissue infiltration.However,there is no broad consensus regarding the association of these factors with AR.This review comprehensively summarized the clinical characteristics,risk factors and personalized management strategies of AR,with an emphasis on the impact of different axillary surgical approaches,radiotherapy and systemic therapy on the AR risk.In addition,more high-quality clinical studies are urgently needed to further clarify prognostic factors and optimize individualized treatment strategies,so as to provide more precise management for patients.

Objective To explore the effect of moxibustion on bone metabolism and the mechanism of bone protection,the effect of moxibustion,a traditional Chinese treatment in patients with rheumatoid arthritis(RA),especially the levels of two biomarkers,interleukin 35(IL-35)and β-catenin in the serum of rheumatoid arthritis patients were investigated.Methods A total of 72 RA patients were randomly assigned equally to the treatment group(36 cases)and 36 patients each of the control group(36 cases).The control group was intervened with standardized Western medicine treatment.For the treatment group,moxibustion intervened on Zusanli,Shenshu,and Ashi acupoints three times a week for 5-week treatment,with the remaining treatments being the same as the control group.The clinical symptom-related scores,routine clinical test indicators,and serum IL-35,β-catenin,BMP-2,IL-1β contents of RA patients before and after treatment were compared between the two groups.Results After treatment,VAS score,DAS28 score,morning stiffness score and BMP-2,β-catenin and IL-1β in serum in 2 groups significantly decreased(P<0.01),while IL-35 content in treatment group significantly increased(P<0.01).VAS score,DAS28 score,morning stiffness score and BMP-2,β-catenin and IL-1β in serum showed the obvious advantage of the treatment group over the control group(P<0.05),but the two groups(P>0.05)have no significant discrepancy in serum IL-35 content.For the treatment group,the improvement values of morning stiffness score and joint swelling number were positively correlated with the improvement values of BMP-2 and β-catenin in serum(P<0.01,P<0.05,r>0).The improvement of serum IL-35 was negatively correlated with the improvement of DAS28 score in the treatment group(P<0.05,r<0).Conclusion On the basis of conventional western medicine treatment,moxibustion may inhibit the levels of IL-35 and IL-1β in serum of RA patients,regulate the Wnt/β-catenin signaling pathway,regulate the levels of β-catenin and BMP-2,reduce the inflammatory response of RA,regulate bone metabolism,and achieve the purpose of bone protection.Thus,bone and joint teratogenesis or disability in RA patients was prevented and delayed.

Objective:To investigate the diagnostic value of plasma cytokines such as interleukin (IL)-2, IL-6 and interferon (IFN)-γ in non-Hodgkin lymphoma (NHL).Methods:A retrospective case-control study was conducted. A total of 48 NHL patients admitted to the Second Affiliated Hospital of Xuzhou Medical University between January 2020 and December 2022 were selected as NHL group, and another 34 healthy people who underwent physical examimation during the same period were selected as the healthy control group. The levels of IL-2, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor (TNF) - α and IFN-γ in the plasma of patients at first admission and healthy subjects during physical examination were detected by using flow cytometry. The differences in general data and all cytokines levels of both groups were compared. The collinearity stepwise screening was made in 7 cytokines levels, and the screened variables were included in multivariate binary logistic regression model. Plasma cytokines with independent effects on the pathogenesis of NHL were screened. Taking local biopsy, histopathological examination or immunohistochemical examination as the gold standard, the receiver operating characteristic (ROC) curves of individual and combined diagnosis of NHL based on the selected cytokines were drawn to judge the diagnostic effect of all indicators on NHL.Results:There were 32 males (66.7%) and 16 females (33.3%) in NHL group, with the median age [ M ( Q1, Q3)] of 56.50 (45.75, 67.50) years; there were 28 males (82.4%) and 6 females (17.6%) in the healthy control group, with the median age of 52.00 (47.50, 55.50) years. There were no statistically significant differences in age and gender composition between the 2 groups (all P > 0.05). The levels of IL-2 [1.44 (1.36, 1.85) pg/ml vs. 1.19 (0.86, 1.68) pg/ml] and TNF-α [3.46 (2.68, 4.06) pg/ml vs. 2.23 (1.52, 3.46) pg/ml] in NHL group were higher than those in the healthy control group, and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in IL-4, IL-6, IL-10, IL-17, IFN-γ levels (all P > 0.05). According to collinear stepwise screening of independent variables, IL-4 and TNF-α were excluded from 7 cytokines, and the other 5 cytokines were included in multivariate logistic regression model, and the result showed that the decreased level of IL-2 ( OR = 0.20, 95% CI: 0.08-0.53, P = 0.001) and the increased levels of IL-6 ( OR = 1.18, 95% CI: 1.04-1.33, P = 0.009) and IFN-γ ( OR = 1.26, 95% CI: 1.08-1.46, P = 0.003) were independent risk factors for the onset of NHL. The results showed that the area under the curve of IL-2, IL-6, IFN-γ and the combination of 3 indexes for the diagnosis of NHL was 0.760 (95% CI: 0.651-0.870), 0.595 (95% CI: 0.468-0.722), 0.508 (95% CI: 0.373-0.642), 0.847 (95% CI: 0.763-0.930), and the optimal cut-off value of the combination of 3 indexes was 0.730 which was calculated by logistic regression model formula; the corresponding sensitivity and specificity were 70.2% and 94.1%, respectively. Conclusions:The decreased level of IL-2 and increased levels of IL-6 and IFN-γ at initial diagnosis are risk factors for the onset of NHL. The combined detection of the 3 indexes shows a good value in the diagnosis of NHL.

Objective:To investigate the clinical efficacy and safety of the triplet regimen of flumatinib, venetoclax (VEN) and azacitidine (AZA) for Philadelphia chromosome-positive (Ph +) mixed-phenotype acute leukemia (MPAL). Methods:The clinical data of 2 Ph + MPAL patients treated with triplet regimen of flumatinib, VEN and AZA who were admitted to the Institute of Hematology & Blood Diseases Hospital of Chinese Academy of Medical Sciences & Peking Union Medical College in February and March 2023 were retrospectively analyzed, and the relevant literature was reviewed. Results:Patient 1 was a 56-year-old female, and patient 2 was a 59-year-old male. Both patients were diagnosed with Ph + B cell/myeloid (B/My) MPAL. After the first course of induction chemotherapy with the triplet regimen, patient 1 achieved hematological complete remission (HCR), complete cytogenetic remission (CCyR) and major molecular response (MMR), and patient 2 achieved HCR and CCyR. During the entire treatment process, the adverse reactions of two patients were mainly fever and ≥ grade 3 hematological adverse reactions, which were relieved after the use of antibiotics and intermittent infusion of blood products. When the patient achieved HCR and received consolidation treatment with the same regimen, the adverse reactions were mild. Conclusions:The triplet regimen of flumatinib, VEN and AZA is safe and effective for the treatment of Ph + MPAL, and is a new induction therapy option for such patients.

Objective:To preliminarily establish a sample clot warning model for coagulation screening tests using 5 machine learning methods.Methods:This cross-sectional study collected 7 401 routine screening test samples from Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, from January 1st, 2015, to August 18th, 2024, including 4 786 clotted (positive) and 2 615 qualified (negative) samples for model development. The dataset was divided into Dataset 1 and Dataset 2 based on a reagent change for APTT in December 2018, with separate models developed for each. An additional 2 493 samples (October 31st to November 8th, 2024) were used to evaluate consistency between the model and manual assessment, while 23 200 samples (October 17th to December 31st, 2024) were used for assessing real-world predictive performance. Five machine learning algorithms were employed to develop the clot prediction model: logistic regression (LR), random forest (RF), extreme gradient boosting (XGBoost), naive bayes (NB), and artificial neural network (ANN), with the ANN model constructed using two different hidden layer and neuron parameter settings. Model selection was based on AUC, accuracy, sensitivity, specificity, F1-score, PPV, and NPV, with the optimal model integrated into the LIS for validation.Results:Among the six models using 5 machine learning algorithms, XGBoost demonstrated the highest performance (AUC=0.961, sensitivity=0.945, F1-score=0.934) and robustness to reagent changes ( Z=-1.333, P=0.113). When deployed, the differences between the model's predictions and manual pre-judgment were statistically significant ( Z=-5.289 to 8.933, all P<0.01). The predictive efficacy indices AUC (95% CI), sensitivity, specificity, and accuracy of the XGBoost model deployed in real-world operation of the LIS were 0.939 (0.918—0.960), 0.958, 0.921, and 0.921 respectively. Conclusion:In this study, a clot warning model for coagulation screening samples was established based on the XGBoost algorithm, and its prediction efficacy is good, providing a foundation for intelligent pre-analytical quality control for coagulation screening tests.

Adverse childhood experiences (ACEs) refer to traumatic events such as abuse and neglect experienced before the age of 18 years, which have negative impacts on an individual's physical and mental health. Studies have shown that ACEs not only increase the risk of health-harming behaviors such as smoking and alcohol abuse, but are also risk factors for depression and anxiety. The influence of ACEs on depression and anxiety exhibits type-specificity, cumulative effects, and temporal dynamics. The impact of ACE types on depression and anxiety varies across populations and genders, a dose-response relationship exists between the number of ACEs and depression/anxiety, and the phase, trajectory, and frequency of ACEs also significantly influence depression and anxiety. This article collected literature on ACEs and depression/anxiety from January 1995 to June 2024 by searching the CNKI and PubMed databases. It provides a comprehensive review of the associations between different ACEs types, quantities, categories, timing, trajectories, frequencies, and the risks of depression and anxiety, while also exploring the underlying mechanisms of these associations. The findings aim to offer references for the prevention and intervention of ACEs and the improvement of mental health.

Cold tumors have a poor response to tumor immunotherapy due to low immune cell infiltration and the ability to evade immune attacks. Converting cold tumors into hot tumors can enhance the clinical effectiveness of anti-tumor immunotherapy. High-intensity focused ultrasound (HIFU) as a non-invasive treatment can damage tumors through mechanical effects, but there is a lack of research on its cytotoxic mechanisms at the cellular level and its role in inducing anti-immune responses. In this study, the role of HIFU in triggering tumor ferroptosis by disrupting the GSH/GSSG balance through mechanochemical action and the associated anti-tumor immune priming effect were investigated. The use of a nano-enhancer loaded with PFOB combined with HIFU could enhance ferroptosis in triple-negative breast cancer at a specific stage of tumor growth (UTGR = 0) while promoting the conversion of a cold tumor into a hot tumor, thereby improving the immune response. Overall, this provides valuable guidance for the clinical application of HIFU in tumor immunotherapy.
