Objective To explore the expression levels of CD33⁺ myeloid-derived suppressor cell (MDSC)-mediated T lymphocyte function and related inflammatory factors secreted by T lymphocyte subsets in patients with cervical cancer, and to analyze their correlation with the treatment efficacy of ¹²⁵I particle implantation combined with arterial chemoembolization, as well as predictive value for treatment outcomes and interaction effects. Methods From January 1st, 2021 to January 1st, 2024, our hospital admitted 152 patients with advanced cervical cancer, who were confirmed by pathological examination. All patients received uterine artery chemoembolization combined with ¹²⁵I particle implantation. The predictive value of CD33⁺MDSC levels for clinical treatment response in cervical cancer was assessed using receiver operating characteristic (ROC) curve analysis. Multivariate logistic regression analysis was performed to evaluate both multiplicative and additive interactions between CD33⁺MDSC and T lymphocytes in predicting clinical treatment failure of cervical cancer. Kaplan Meier method was used to analyze the survival differences between cervical cancer patients with high and low CD33⁺MDSC expression levels. Results Compared with the effective group, patients in the ineffective group had decreased expression levels of CD3⁺ T lymphocyte, CD4⁺ T lymphocyte, interleukin 2 (IL-2) and interferon γ (IFN-γ), while showing increased expression levels of CD33⁺MDSC, CD8⁺ T lymphocyte, IL-4 and IL-6, along with increased tumor necrosis factor α (TNF-α) levels, larger maximum tumor diameters, and a higher incidence of lymph node metastasis. The expression levels of CD33⁺MDSCs demonstrated good predictive performance for treatment efficacy in cervical cancer patients. The high CD33⁺MDSC expression group had a significantly shorter overall survival (OS) than the low CD33⁺MDSC expression group (6.0±1.0 months vs. 12.0±1.2 months; t=33.280). The interaction analysis revealed that CD33⁺MDSCs and CD8⁺ T lymphocytes were highly expressed, while CD3⁺ and CD4⁺ T lymphocytes were lowly expressed, which was associated with an increased risk of clinical treatment failure in cervical cancer patients. Conclusion CD33⁺MDSCs can inhibit CD3⁺ and CD4⁺ T lymphocytes. It can upregulate the expression of CD8⁺ T lymphocytes, form an immunosuppressive microenvironment, and reduce the treatment response rate of ¹²⁵I particle implantation combined with arterial chemoembolization. CD33⁺MDSCs may serve as an independent biomarker for predicting the therapeutic efficacy and poor prognosis.

Surgical methods for varicocele remain controversial. This study intends to evaluate the efficacy and safety of different surgical approaches for treating varicocele through a network meta-analysis (NMA). PubMed, Embase, Cochrane, and Web of Science databases were thoroughly searched. In total, 13 randomized controlled trials (RCTs) and 24 cohort studies were included, covering 9 different surgical methods. Pairwise meta-analysis and NMA were performed by means of random-effects models, and interventions were ranked based on the surface under the cumulative ranking curve (SUCRA). According to the SUCRA, microsurgical subinguinal varicocelectomy (MSV; 91.6%), microsurgical retroperitoneal varicocelectomy (MRV; 78.2%), and microsurgical inguinal varicocelectomy (MIV; 76.7%) demonstrated the highest effectiveness in reducing postoperative recurrence rates. In this study, sclerotherapy embolization (SE; 87.2%), MSV (77.9%), and MIV (67.7%) showed the best results in lowering the risk of hydrocele occurrence. MIV (82.9%), MSV (75.9%), and coil embolization (CE; 58.7%) were notably effective in increasing sperm motility. Moreover, CE (76.7%), subinguinal approach varicocelectomy (SV; 69.2%), and SE (55.7%) were the most effective in increasing sperm count. SE (82.5%), transabdominal laparoscopic varicocelectomy (TLV; 76.5%), and MRV (52.7%) were superior in shortening the length of hospital stay. The incidence rates of adverse events for MRV (0), SE (3.3%), and MIV (4.1%) were notably low. Cluster analyses indicated that MSV was the most effective in the treatment of varicocele. Based on the existing evidence, MSV may represent the optimal choice for varicocele surgery. However, selecting clinical surgical strategies requires consideration of various factors, including patient needs, surgeon experience, and the learning curve.

The patient, a 20-day-old male, was admitted due to respiratory distress that had persisted for 20 days after birth. The main clinical manifestations included gradually worsening respiratory distress and edema. The patient received treatment including mechanical ventilation and diuretics. Echocardiography indicated cardiomegaly, pulmonary hypertension, and heart failure. A comprehensive systemic examination revealed a significant blowing vascular murmur upon auscultation over the anterior fontanelle and bilateral temporal regions. Further imaging studies including cranial magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance venography showed marked dilation of the superior sagittal sinus, transverse sinus, and sigmoid sinus, leading to a definitive diagnosis of dural arteriovenous fistula. After a multidisciplinary consultation, the patient underwent cerebral angiography and partial embolization of the left parietal arteriovenous fistula. Postoperatively, the patient was treated with positive inotropes, diuretics, and fluid restriction. Ultimately, the patient was weaned off the ventilator and discharged in improved condition. This article reports a case of neonatal dural arteriovenous fistula presenting with respiratory distress and discusses the multidisciplinary approach to managing this condition, which aids in early disease recognition and guides clinical decision-making.

OBJECTIVE: To investigate the effect of innovative perioperative pain management on prostate cancer patients with hematuria undergoing prostatic artery embolization (PAE). METHODS: A total of 60 patients undergoing PAE in the Interventional Therapy Department of General Hospital of Eastern Theater Command from May 2024 to January 2025 were selected by convenience sampling method and randomly divided into the intervention group and the control group, with 30 patients in each group. The control group received traditional pain management of nursing. An innovative perioperative pain management was performed in intervention group including preoperative "body-mind-pain" holistic assessment and preparation, intraoperative humanistic care and real-time support, postoperative multimodal analgesia and rehabilitation, dynamic monitoring and closed-loop feedback. The pain degree after 6 hours, 1 day, 3 days and 1 week of the operation, and the quality of life after 1 week of operation, as well as nursing satisfaction at discharge were compared between the two groups. RESULTS: The VAS scores of the intervention group were significantly lower than those of the control group after 6 hours, 1 day, 3 days and 1 week of operation (P<0.05). One week after the operation, the quality of life in the observation group was higher than that of the control group significantly (P<0.05). The nursing satisfaction of the observation group was significantly higher than that of the control group at discharge(P<0.05). CONCLUSION The application of innovative perioperative pain management can alleviate pain of patients with PAE, which improves the quality of life and nursing satisfaction of patients, and is conducive to the rehabilitation of patients.

Retained products of conception (RPOC) represent a common pregnancy-related condition that may lead to complications such as abnormal uterine bleeding, infection, secondary arteriovenous fistula, intrauterine adhesions, and infertility. Currently, the main clinical treatments for RPOC include surgical intervention, medical therapy, and expectant management, sometimes supplemented by high-intensity focused ultrasound or uterine artery embolization when necessary. However, no standardized treatment guidelines exist. Medical and expectant management may help some patients avoid or reduce the need for surgery, though these approaches often involve a prolonged disease course. While surgery yields rapid results, patients with large lesions may require multiple procedures, increasing the risk of endometrial damage and intrauterine adhesions. There is still a lack of robust evidence-based guidance for selecting the optimal or individualized treatment approach. This review explores recent advances in the management of RPOC, with an emphasis on strategies that effectively preserve the endometrium, safeguard fertility, and support more precise, minimally invasive, and efficient personalized treatment.

Bronchial artery embolization (BAE) plays a crucial role in the treatment of hemoptysis, and its efficacy and safety have been proved. Although BAE is widely used in the treatment of hemoptysis, there is currently no standardized procedure for BAE, and there are significant differences between institutions and operators. To achieve standardization and normalization of the BAE in the treatment of hemoptysis, the Chinese College of Interventionalists (CCI) proposed this expert consensus, which is based on existing evidence and combined with clinical practice in China. This expert consensus is about patient selection, preoperative preparation, intraoperative procedures, postoperative management, efficacy evaluation and follow-up. After multiple rounds of discussion, this "expert consensus on the bronchial artery embolization in the treatment of hemoptysis" was proposed.

Hemoptysis is a serious medical emergency associated with high mortality rates. Notably, it poses significant therapeutic challenges owing to the complexities in rapidly identifying the bleeding site and underlying cause. In severe cases, it can lead to death by asphyxia, thus necessitating prompt intervention. Bronchoscopy-guided endobronchial balloon occlusion (EBBO) is a vital procedure for blocking the bleeding bronchus, allowing time for subsequent embolization of the responsible vessel and definitive treatment. While traditional techniques for EBBO are intricate and demanding, recent advancements in balloon technology, along with procedural refinements, have simplified the process, reduced operation times, and enhanced medical staff proficiency. Nevertheless, a lack of standardized protocols and technical guidelines has hindered the widespread adoption of this technique in China. Accordingly, the Internal Medicine of Chinese Medical Association convened a group of experts to develop the "Expert consensus on endobronchial balloon occlusion in the treatment of hemoptysis (2025 edition)" to standardize this procedure. This consensus, grounded in evidence-based medicine and clinical practice both domestically and internationally, covers seven essential elements: treatment strategies, equipment, indications and contraindications, preoperative preparation, technical procedures and specifications, integration with other therapeutic techniques, efficacy assessment, and follow-up. By offering comprehensive guidance, the consensus aims to standardize and promote the use of EBBO for hemoptysis management in China.

OBJECTIVE: To investigate the safety and effectiveness of balloon occlusion and intra-sac thrombin injection in the endovascular repair of ruptured abdominal aortic aneurysm. METHODS: From October 2019 to October 2022, the clinical data of 16 patients with rAAA treated with balloon occlusion technique and intra-sac thrombin injection combined with EVAR were retrospectively analyzed, including 13 males and 3 females, aged 42-85 years, with a median age of 70.5 years. The time of preoperative first aid (from hospital arrival to operation start), average operation time, stay in intensive care unit (ICU), average hospitalization time, success rate of surgical treatment, perioperative (30 d) mortality rate, incidence of complications, the maximum diameter and volume change of the aneurysm were observed and recorded. RESULTS: Among the 16 patients with ruptured abdominal aortic aneurysm, the technical success rate was 100.0% (16/16). One patient died of multiple organ dysfunction 6 hours after operation. The success rate of surgical treatment was 93.8% (15/16). The preoperative first aid time was (53.3±6.2) min, the average operation time was (89.9±17.1) min, the stay in the intensive care unit (ICU) was (1.7±0.8) d, and the average hospitalization time was (7.8±1.3) d. The intraoperative balloon occlusion time was (32.4±4.1) min. The postoperative renal function of all the patients had no significant deterioration compared with that preoperative. Abdominal compartment syndrome (ACS) occurred in 1 patient after operation, which improved after CT puncture and drainage. The median follow-up time was 36 months. During the follow-up period, 1 patient died of acute myocardial infarction 2 years after operation, and the remaining 14 patients survived. Among the 14 follow-up patients, 1 type Ⅱ endoleak occurred, and no other types of endoleak occurred. By the end of the follow-up, the maximum diameter of the aneurysm sac in 14 patients was significantly lower than that before operation [(44.6±8.0) mm vs.(66.0±15.5) mm, P < 0.001], and in 12 patients with CTA, the volume of the aneurysm sac was significantly shrunk than that before operation [(311.7±170.3) mm³ vs. (168.6±68.1) mm³, P < 0.05]. CONCLUSION Balloon occlusion during endovascular repair is safe and effective in the treatment of ruptured abdominal aortic aneurysm; intraoperative thrombin injection of the aneurysm sac can significantly reduce the incidence of intraoperative and postoperative abdominal compartment syndrome and endoleak and, to a certain extent, improve the success rate of treatment.

Objective:To investigate the clinical effect of plasma resection of juvenile nasopharyngeal angiofibroma（JNA） under nasal endoscope. Methods:The clinical data of 12 cases with JNA treated in the Department of Otorhinolaryngology and head and neck surgery of the 940th Hospital from 2015.01 to 2020.01 were analyzed retrospectively. All of them were young males. Imaging examination, digital subtraction angiography（DSA） and selective blood supply artery embolization were performed before operation, and then plasma was used to remove the tumor under nasal endoscope. The patients were followed up for at least 30 months. During the follow-up, the nasal cavity was observed under nasal endoscope and the tumor recurrence was observed by imaging examination. Results:In 12 cases, the vision was clear, the amount of bleeding was less, the operation time was within 2 h, and the postoperative recovery time was short. 12 cases were followed up and no tumor recurrence was found by nasal endoscopy and imaging examination. Conclusion:Selective external carotid artery embolization before operation and plasma resection of JNA under nasal endoscope during operation is a safe and effective treatment, which can effectively improve the cure rate and reduce the recurrence rate.
