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.

OBJECTIVE:
To analyze the clinical characteristics and risk factors of patients with oral bleeding.
METHODS:
A retrospective study was performed on patients with oral bleeding in the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2019 to December 2022. The distribution of the patients ' gender, age, cause of bleeding, systemic condition, treatment methods and risk factors of hemostasis methods, and number of visits were analyzed.
RESULTS:
A total of 4 764 patients with oral bleeding were enrolled, including 2 660 males (55.84%) and 2 104 females (44.16%), with an average age of 40.7 years. The most common causes of oral bleeding were bleeding after tooth extraction (3 080 cases, 64.65%), followed by gingival bleeding (1 386 cases, 29.09%), bleeding after outpatient surgery (194 cases, 4.07%), maxillofacial mass bleeding (33 cases, 0.69%), postoperative bleeding of inpatient (24 cases, 0.50%), and bleeding from other causes (47 cases, 0.99%). Simple hemostatic methods were applied in 1 867 cases (39.19%) while 2 897 cases (60.81%) used complex methods, among which iodine strip tamponade and suture were the most commonly used methods of hemostasis. Logistic regression analysis showed that the male patients had a higher proportion of complex methods than the female patients; gingival bleeding were often stopped by simple hemostatic methods while complex methods were more likely to be applied in the patients with bleeding after tooth extraction. The patients with hypertension and coagulation disorders were more likely to visit the hospital for repeated bleeding. Gender and age did not affect the number of visits.
CONCLUSION
Oral bleeding was one of the common diseases in oral emergency. The common causes were bleeding after tooth extraction and gingival bleeding. Most patients could be treated by compression, local suture and packing of iodine strips while some cases with severe bleeding needed further treatment to stop bleeding. A minority of patients with oral bleeding could induce systemic complications, which should be paid full attention by clinicians.

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.

8.Expert consensus on the bronchial artery embolization in the treatment of hemoptysis.
Chinese Journal of Internal Medicine 2025;64(3):191-199
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.

9.Expert consensus on endobronchial balloon occlusion in the treatment of hemoptysis (2025 edition).
Chinese Journal of Internal Medicine 2025;64(11):1055-1064
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.

10.Progress in application of medical absorbable haemostatic materials for haemostasis in orthopaedic surgery.
Chinese Journal of Reparative and Reconstructive Surgery 2024;38(11):1421-1426
OBJECTIVE:
The application progress of medical absorbable haemostatic material (MAHM) in hemostasis during orthoapedic surgery was reviewed, in order to provide reference for clinical hemostasis program.
METHODS:
The domestic and foreign literature on the application of MAHM for hemostasis in orthopedic surgery was extensively reviewed and summarized.
RESULTS:
According to biocompatibility, MAHM can be divided into oxidized cellulose/oxidized regenerated cellulose materials, chitosan and its derivatives materials, starch materials, collagen and gelatin materials, and fibrin glue materials, etc., which can effectively reduce blood loss when used in orthopedic surgery for hemostasis. Each hemostatic material has different coagulation mechanism and suitable population. Oxidized cellulose/oxidized regenerated cellulose, chitosan and its derivatives, starch hemostatic material mainly stops bleeding by stimulating blood vessel contraction and gathering blood cells, which is suitable for people with abnormal coagulation function. Collagen, gelatin and fibrin glue hemostatic materials mainly affect the physiological coagulation mechanism of the human body to stop bleeding, suitable for people with normal coagulation function.
CONCLUSION
Reasonable selection of MAHM can effectively reduce perioperative blood loss and reduce the risk of postoperative complications, but at present, single hemostatic material can not meet clinical needs, and a new composite hemostatic material with higher hemostatic efficiency needs to be developed.
