Myelodysplastic syndrome (MDS), a myeloid tumor derived from the malignant clones of hematopoietic stem cells, has an annually increasing incidence. The contemporary research direction has shifted to analyzing the synergistic effect of immune surveillance collapse and abnormal bone marrow microenvironment in the pathological process of MDS. Against this backdrop, the immune checkpoint molecule TIM3 has emerged as a key target because of its persistently high expression on the surface of important immune cells such as T and NK cells. The abnormal activation of the TIM3 pathway is the mechanism by which solid tumors and hematological malignancies achieve immune escape and is a key hub in the formation of immune exhaustion phenotypes. This work integrates the original discoveries of our team with the latest international progress, systematically demonstrating the bidirectional regulatory network of TIM3 between the malignant clone proliferation of MDS and the immunosuppressive microenvironment. Integrating the evidence from emerging clinical trials allows us to consider the clinical significance of TIM3-targeted blocking for MDS, providing a transformative path to overcome the resistance of traditional treatments and marking a new chapter in the active immune reconstitution of MDS treatment.

With the widespread use of antimicrobial agents, bacterial drug resistance has become an increasingly severe issue, posing significant challenges to global healthcare. Traditional Chinese medicine (TCM) has emerged as a research focus in the field of bacterial resistance due to its broad sources, high safety profile, low toxicity, and antimicrobial mechanisms distinct from those of chemical drugs. Studies have shown that various TCM herbs, such as Scutellaria baicalensis, exert antibacterial effects through multiple pathways, including disrupting the integrity of bacterial cell walls and membranes, inhibiting nucleic acid and protein synthesis, and impairing energy production and metabolism. Additionally, certain TCM herbs, including Scutellaria baicalensis, Coptis chinensis, and Fritillaria thunbergii, can reverse antimicrobial resistance by eliminating resistant plasmids, inhibiting bacterial efflux pump function, and suppressing β-lactamase activity. TCM holds promising potential for antibacterial applications and synergistically reversing antimicrobial resistance, though systematic analyses remain limited. This review summarizes the mechanisms of antibacterial action of TCM and current research on its synergistic use with antimicrobial agents to reverse drug resistance, aiming to provide insights for developing novel TCM-based antimicrobials and addressing bacterial resistance.

Objective:To understand the iodine nutritional status of pregnant women in Beijing, and analyze the influencing factors of thyroid disease.Methods:From 2021 to 2023, a stratified random sampling method was used to select at least 100 pregnant women from each of the 16 administrative districts under the jurisdiction of Beijing each year, using cross-sectional survey. Random urine samples and household salt samples were collected to determine urinary iodine and salt iodine levels, and were analyzed iodine nutritional status. Binary logistic regression model and restricted cubic spline(RCS) model were sued to analyze the influencing factors of thyroid disease in pregnant women (age, residential area, ethnicity, pregnancy, etc.).Results:A total of 4 878 pregnant women were investigated from 2021 to 2023, and the overall median urinary iodine level was 129.11 μg/L, indicating a deficiency in iodine nutrition (< 150 μg/L). There was a statistically significant difference in the urinary iodine levels of pregnant women between different years ( H = 20.22, P < 0.001). There was a statistically significant difference in median urinary iodine levels of pregnant women in different pregnancy stage ( H = 11.57, P = 0.003). The median of salt iodine value was 24.00 mg/kg, and the consumption rate of qualified iodized salt was 75.05% (3 661/4 878). The comparison of salt iodine levels between different years showed statistically significant differences ( H = 14.20, P < 0.001). Binary logistic regression analysis showed that the risk of thyroid disease in urban area was higher than that in suburban area ( OR = 2.01, P < 0.001), while the risk of disease in central government areas was lower ( OR = 0.52, P = 0.044). Compared with late pregnancy, the risk of the disease was lower in the early pregnancy ( OR = 0.60, P = 0.003) and the middle pregnancy ( OR = 0.71, P = 0.046). Supplementing with iodine can reduce the risk of the disease ( OR = 0.48, P < 0.001). The analysis of the RCS model showed that there was a nonlinear dose-response relationship between the risk of thyroid diseases in pregnant women and urinary iodine, with a U-shaped curve and cut-off values of 127.74, 472.66 μg/L. Conclusion:From 2021 to 2023, the iodine nutrition of pregnant women in Beijing is in iodine deficiency state, and factors affecting thyroid disease include residential area, pregnancy, supplementing with iodine, and urinary iodine.

Cutaneous melanoma is a malignant skin cancer with a poor prognosis.However,re-cent advances in immune checkpoint blockade and targeted therapy have significantly improved outcomes in advanced-stage resectable melanoma,which have made neoadjuvant therapy a viable option for melanoma patients.Currently,several relevant clinical trials on neoadjuvant therapy have achieved significant results.This paper reviews the recent advances in neoadjuvant therapy for cutaneous melanoma,focusing on the selection of neoadjuvant therapy,subsequent surgical considerations after neoadjuvant therapy,prognostic indicators,and baseline biomarkers.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the efficacy of different types of neoadjuvant therapy for esophageal cancer.Methods:The clinical data of 542 patients with esophageal squamous cell carcinoma (ESCC) who received neoadjuvant therapy in Anyang Tumor Hospital of Science and Technology from January 2015 to May 2022 were retrospectively analyzed. These patients, consisting of 198 females and 344 males, with 289 cases aging ≤ 65 and 253 cases aging >65, were divided into a neoadjuvant chemoradiotherapy (NCRT) group (137 cases), a neoadjuvant chemotherapy (NCT) group (241 cases), and a neoadjuvant immunotherapy plus chemotherapy (NICT) group (164 cases). In this study, primary endpoints included major pathological response (MPR) and pathologic complete response (pCR) rates, and secondary endpoints comprised overall survival (OS), progression-free survival (PFS), and safety. Survival analysis was performed using the Kaplan-Meier method, and inter-group comparisons were made using the Log-rank test. Furthermore, prognostic factors were analyzed based on the Cox proportional hazards regression model.Results:The NCRT, NCT, and NICT groups exhibited MPR and pCR rates of 66.4% (91/137) and 35.3% (85/241), 63.4% (104/164) and 35.8% (49/137), and 6.6% (16/241) and 31.1% (51/164), respectively ( χ2=1.67, P < 0.001). These groups displayed 1-, 2-, and 3-year OS rates of 89.8%, 85.9%, and 91.9%; 82.3%, 71.4%, and 81.5%; and 72.3%, 61.4%, and 77.8%, respectively, with significant differences ( χ2=9.20, P < 0.01). Furthermore, they exhibited 1-, 2-, and 3-year PFS rates of 81.5%, 75.9%, and 80.1%; 67.9%, 61.0%, and 65.5%; and 66.6%, 53.5%, and 65.3%, respectively, with significant differences ( χ2=4.62, P < 0.05). Multivariate analysis showed that therapeutic modality, T stage, and N stage were independent prognostic factors for OS ( P < 0.05). Additionally, there was no difference in adverse reactions and postoperative complications among the three groups. Conclusions:Compared to NCT, NICT and NCRT feature higher pCR and MPR rates, along with more survival benefits. Therefore, neoadjuvant immunotherapy has the potential to serve as a preoperative therapeutic modality for esophageal cancer, yet large-scale randomized controlled trials are still required for confirmation.

Objective:To evaluate the efficacy and safety of immunotherapy with or without radiotherapy in the treatment of recurrent or metastatic esophageal squamous cell carcinoma (R/M ESCC).Methods:A retrospective analysis was conducted on the data of 75 patients with R/M ESCC treated with sintilimab at Anyang Tumor Hospital from January 2020 to October 2021. The patients were divided into the radiotherapy (RT) group ( n=37) and non-radiotherapy (NRT) group ( n=38) based on whether they received radiotherapy. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and adverse effects were compared between two groups. Count data were expressed as composition ratios and analyzed using Chi-square test or Fisher's exact test. Survival analysis was performed using Kaplan-Meier method and log-rank test. Results:There was no statistically significant difference in ORR and DCR between the RT and NRT groups (70% vs. 61%, P=0.375; 95% vs. 89%, P=0.414). However, the complete response (CR) rate in the RT group was higher compared to that in the NRT group (19% vs. 3%, P=0.022). The median follow-up duration was 25.4 months. There was no statistically significant difference in the median PFS and OS between the RT and NRT groups (13.8 months vs. 9.9 months, P=0.221; 20.2 months vs. 18.9 months, P=0.214). Subgroup analysis demonstrated that among patients with recurrence or metastasis confined to local and / or ≤3 distant lymph nodes, there was no statistically significant difference in the median PFS between the RT and NRT groups (15.1 months vs. 8.4 months, P=0.115), but the median OS in the RT group was better than that in the NRT group (not reached vs. 12.3 months, P=0.036). Compared to the NRT group, besides an increase in grade 1-2 pneumonitis (41% vs. 18%, P=0.035), no significant increase in treatment-related toxicity was observed in the RT group. Conclusion:Immunotherapy combined with radiotherapy is safe in patients with R/M ESCC, and shows survival benefit in patients with recurrence or metastasis confined to local and / or ≤3 distant lymph nodes.

OBJECTIVE To systematically evaluate the efficacy and safety of intrawound vancomycin powder for preventing surgical site infections in total knee and total hip arthroplasty. METHODS Computer retrieval of PubMed, Embase, Web of Science, the Cochrane Library, CNKI, Wanfang Database, Chinese Biomedical Literature Database, The clinical research about intrawound vancomycin in total knee arthroplasty(TKA) and total hip arthroplasty(THA) for the prevention of surgical site infections were screened. The quality of included studies was assessed using the Cochrane risk bias assessment tool and the Newcastle-Ottawa Scale. Meta-analysis was performed using RevMan 5.4 software. RESULTS Finally, 20 literature were included, including 1 prospective randomized controlled trial, 2 prospective cohort study, and 17 retrospective cohort study, with a total of 34900 patients. Meta-analysis showed that interventional group had a decreased tolal rate of prosthetic joint infection(PJI)[OR=0.44, 95%CI(0.35−0.56), P<0.000 01] and superficial infection[OR=0.27, 95%CI(0.19−0.41), P<0.000 01]compared with control group. Subgroup analysis showed that TKA and THA, primary and revision patients who received intrawound vancomycin had lower rates of PJI, the differences were statistical significance(P<0.05). Meta-analysis of 11 studies reported adverse reaction suggested that the total rate of adverse reactions in the intervention group(7.68%) was higher than that in the control group(5.68%) with significant differences[OR=1.47, 95%CI(1.14−1.89), P=0.003)]. CONCLUSION The current literature suggests that intrawound vancomycin can decrease the rate of PJI and superficial infection in primary and revision TKA and THA , however, it may increase risk of aseptic wound complications and other adverse reaction.
