Cardiotoxicity induced by antineoplastic agents is an important factor affecting the prognosis of cancer patients. This article systematically summarizes the clinical manifestations of cardiotoxicity caused by chemotherapeutic drugs, molecular targeted cancer therapies, and immunotherapeutic drugs, and identifies the core injury mechanisms, including cardiomyocyte apoptosis, oxidative stress, and mitochondrial dysfunction. In Traditional Chinese Medicine (TCM) theory, anticancer drug-induced cardiotoxicity falls under the category of “heat toxins” characterized by dual deficiency of qi and blood, upward flaming of heart heat, stagnation of the heart vessels, and meridian obstruction induced by phlegm-dampness. Therefore, by reviewing the preventive and therapeutic effects and the underlying mechanisms of tonic medicines, interior heat-clearing medicines, blood-circulating and stasis-resolving medicines, phlegm-transforming, cough-suppressing and panting-relieving medicines, and interior-warming medicines, this paper concludes that TCM prevention and treatment of this condition adheres to the formulation principle of “reinforcing healthy qi, removing toxins, and resolving blood stasis”. Its mechanisms of action—including antioxidation effects, regulation of autophagic balance, antagonism of inflammatory responses, and improvement of microcirculation—are highly consistent with modern medical treatment strategies (e.g., dexrazoxane for inhibiting iron-dependent oxidative stress, statins for anti-inflammatory effects). This study provides theoretical support and practical guidance for the collaborative and precise prevention and treatment of anticancer drug-induced cardiotoxicity through the integration of traditional Chinese and Western medicine.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [¹⁵N₂]-cystine and [¹³C₅]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

Objective:To explore the clinical effect of thin superficial circumflex iliac artery perforator flap with venous superdrainage in treatment of wound in extremities.Methods:Clinical data of 20 patients who were treated from January 2018 to January 2024 in the Department of Burns and Plastic Surgery, Affiliated Hospital of Zunyi Medical University were retrospectively analysed. The soft tissue defects in extremity were reconstructed with thin perforator flaps of superficial iliac circumflex artery with venous superdrainage. There were 13 patients with upper limb defects and 7 with ankle defects. Of the defects, 12 were of trauma, 2 of tumour resection, 3 of scar release surgery and 3 of donor flat harvesting. The defects ranged from 5.0 cm×4.0 cm to 18.0 cm×7.0 cm in size. During the surgery, portable Doppler was used to detect the perforating branches of the superficial rotational iliac artery and design flaps. The flaps were 5.0 cm×5.0 cm to 20.0 cm×7.0 cm in size, including 16 single-lobed flaps, 3 double-lobed flaps and 1 triple-lobed flaps. The flaps were 2-7 mm in thickness, with an average of 4 mm. Based on the distribution of perforators, the flaps carried the superficial helioiliac artery and the accompanying vein, as well as the superficial helioiliac vein. The superficial helioiliac artery and the accompanying vein were anastomosed during the surgery, and the superficial helioiliac vein was anastomosed to the superficial or deep vein of the recipient site for superreflux. The donor sites were all directly sutured and closed. Postoperative follow-up was conducted by visits of outpatient clinic, and via telephone and WeChat interviews. The survival and appearance of the flaps and complications were observed.Results:A total of 22 arteries and 42 veins of the 20 flaps were anastomosed in surgery. All flaps survived. The donor sites were closed in the first stage. No vascular compromise occurred. One patient had early exudate under the flap on the exposed wound of interphalangeal joint, which healed after routine dressing change and drainage. All patients were included in the postoperative follow-up, with a peroid over 5 to 40 months, at 10.8 months in average. The flaps were thin and soft, with good wear resistance and without pigmentation. The healing of donor sites was good except 1 donore site that had early lymphatic leakage, which was cured after compression and drainage. A linear scar left at the donor sites and it was acceptable to the patients.Conclusion:The treatment of defective soft tissue wounds in extremities using thin perforator flap with venous superdrainage of the superficial circumflex iliac artery is safe and feasible. No further flap thinning surgery is required, and there is a reliable clinical effect.

Pancreatic cancer is a kind of highly malignant tumor with a low survival rate and poor prognosis. The effectiveness of gemcitabine as a first-line chemotherapy drug is limited; however, it can activate dendritic cells and improve antigen presentation which increase the sensitivity of tumor cell to immunotherapy. Although immunotherapy has made some advancements in cancer treatment, the therapeutic benefit of programmed cell death receptor 1/programmed death receptor-ligand 1 (PD-1/PD-L1) blockade therapy remains relatively low. The chemokine C-X-C chemokine ligand 12 (CXCL12) contributes to an immunosuppressive tumor microenvironment by recruiting immunosuppressive cells. The receptor C-X-C motif chemokine receptor 4 (CXCR4), highly expressed in various tumors including pancreatic cancer, plays a crucial role in tumor development and progression. In this study, the anti-tumor immune response of human peripheral blood mononuclear cell (hPBMC) was enhanced using the combination of BsNb PX4 (anti-PD-L1&CXCR4 bispecific nanobody) and gemcitabine. In a co-culture system of gemcitabine-pretreated hPBMCs with tumor cells, the BsNb PX4 synergized gemcitabine to improve the cytotoxic activity of hPBMCs against tumor cells. Flow cytometry analysis confirmed increased ratio of CD8⁺ to CD4⁺ T cells in combination treatment. In NOD/SCID mice bearing pancreatic cancer, the combination treatment exhibited more infiltration of CD8⁺ T cells into tumor tissues, contributing to an effective anti-tumor response. This study presents potential new therapies for the treatment of pancreatic cancer. Ethical approval was obtained for collection of hPBMC samples from the Local Ethics Committee of Shanghai Jiao Tong University. All animal experiments were approved by the Animal Ethic Committee of Shanghai Jiao Tong University (authorizing number: A2024246).

OBJECTIVE: To compare the effectiveness of single-stage vascularized lymph node transfer (VLNT) combined with lymphaticovenular anastomosis (LVA) and liposuction (LS) (3L) versus LVA combined with LS (2L) for the treatment of moderate-to-late stage upper limb lymphedema following breast cancer surgery. METHODS: A retrospective analysis was conducted on the clinical data of 16 patients with moderate-to-late stage upper limb lymphedema after breast cancer surgery, treated between June 2022 and June 2024, who met the selection criteria. Patients were divided into 3L group (n=7) and 2L group (n=9) based on the surgical approach. There was no significant difference (P>0.05) in baseline data between the groups, including age, body mass index, duration of edema, volume of liposuction, International Society of Lymphology (ISL) stage, preoperative affected limb volume, preoperative circumferences of the affected limb at 12 levels (from 4 cm distal to the wrist to 42 cm proximal to the wrist), preoperative Lymphoedema Quality of Life (LYMQoL) score, and frequency of cellulitis episodes. The 2L group underwent LS on the upper arm and proximal forearm and LVA on the middle and distal forearm. The 3L group received additional VLNT in the axilla, with the groin serving as the donor site. Outcomes were assessed included the change in affected limb volume at 12 months postoperatively, and comparisons of limb circumferences, LYMQoL score, and frequency of cellulitis episodes between preoperative and 12-month postoperative. Ultrasound evaluation was performed at 12 months in the 3L group to assess lymph node viability. RESULTS: Both groups were followed up 12-20 months, with an average of 15.13 months. There was no significant difference in the follow-up time between the groups (t=-1.115, P=0.284). All surgical incisions healed by first intention. No adverse events, such as flap infection or necrosis, occurred in the 3L group. At 12 months after operation, ultrasound confirmed good viability of the transferred lymph nodes in the 3L group. Palpation revealed significant improvement in skin fibrosis and improved skin softness in both groups. Affected limb volume significantly decreased in both groups postoperatively (P<0.05). The reduction in limb volume significantly greater in the 3L group compared to the 2L group (P<0.05). Circumferences at all 12 measured levels significantly decreased in both groups compared to preoperative values (P<0.05). The reduction in circumference at all 12 levels was better in the 3L group than in the 2L group, with significant differences observed at 7 levels (8, 12, 16, 30, 34, 38, and 42 cm) proximal to the wrist (P<0.05). Both groups showed significant improvement in the frequency of cellulitis episodes and LYMQoL scores postoperatively (P<0.05). While the improvement in LYMQoL scores at 12 months did not differ significantly between groups (P>0.05), the reduction in cellulitis episodes was significantly greater in the 3L group compared to the 2L group (P<0.05). CONCLUSION The combination of VLNT+LVA+LS provides more durable and comprehensive outcomes for moderate-to-late stage upper limb lymphedema after breast cancer surgery compared to LVA+LS, offering an improved therapeutic solution for patients.

OBJECTIVE: To investigate the clinical characteristics, treatment and prognosis of adult AML patients with NUP98::HOXA9 fusion gene. METHODS: From May 2017 to October 2023， among 2 113 AML patients who visited the Hematology Department of our hospital, patients with NUP98 rearrangements were screened. The clinical characteristics, chromosome karyotypes, immunophenotypes, gene mutations, treatment efficacy and prognosis of the patients with NUP98::HOXA9 positive were analyzed. RESULTS: Among the 2 113 AML patients, there were 18 cases with NUP98 rearrangement, including 14 NUP98::HOXA9 positive cases, with a detection rate of 0.66% (14/2 113). The median age of the NUP98::HOXA9 positive patients was 42.5 (23-64) years old. The most common chromosome karyotype was t(7; 11)(p15; p15). The immunophenotypes of all patients expressed CD13, CD33, CD117 and CD38, and most patients expressed CD34 and cMPO, while only a few expressed HLA-DR. Second-generation sequencing (NGS) was performed to detect genetic mutations associated with leukemia in all 14 patients, and the genes exhibiting a high frequency of mutation were WT1 (10/14), TET2 (7/14), and FLT3-ITD (6/14). Additionally, mutations were also observed in KRAS/NRAS, IDH1, and KIT. Of the 13 patients who received treatment, 9 achieved complete remission (CR), and all 3 patients who received azacytidine(AZA)+ venetoclax (VEN) regimen achieved CR after the first course of treatment. Within this cohort, 6 patients were classified as relapsed/refractory (6/13). 4 patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), of which two achieved long-term survival. The median follow-up time was 12 (2.1-65.0) months, while the median overall survival (OS) and relapse-free survival (RFS) were recorded as 11.4 months and 9.6 months, respectively. CONCLUSION The most common type of NUP98 rearrangement in adults AML patients is NUP98::HOXA9 , which is often accompanied by somatic mutations in WT1, TET2, and FLT3-ITD. These patients are prone to relapse, have short survival time, and generally face poor prognoses. Hopefully, utilization of the AZA+VEN regimen is anticipated to enhance the rate of induced remission in the patients, and some patients may prolong their survival through allo-HSCT. However, more effective treatment methods are still needed to improve the overall prognosis of these patients.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.
