Objective:To explore the feasibility and preliminary efficacy of domestic single-port robotic surgical system in the surgical treatment of thyroid cancer. Methods:Thyroid cancer patients who underwent domestic single-port robotic surgery in the Department of Head and Neck Surgery of Sichuan Cancer Hospital from June 2024 to January 2025 were prospectively included. Clinical data, oncological characteristics, and perioperative indicators were systematically collected. Results:A total of 7 patients were included, including 3 males and 4 females, with an age of （34.57±10.26） years. All procedures were successfully completed without conversion to open surgery. Operative time was（180.00±30.41） minutes. Blood loss was（5.00[15.00 ]）mL. Postoperative drainage volume was （167.86±130.95） mL. The postoperative pathological results were all thyroid papillary carcinoma. There were no system failures, no device-related complications and adverse events were observed during the operation and perioperative period. No tumor recurrence or metastasis was observed during the follow-up period. Conclusion:Preliminary data indicate that the domestic single-port robotic surgical system is safe and feasible for the surgical treatment of thyroid cancer, providing a practical basis for subsequent multi-disease, multi-center, and large-sample studies.

Most cancers are currently incurable, partly due to abnormal post-translational modifications (PTMs). In this study, we initially used multiple myeloma (MM) as a working model and found that SUMOylation activating enzyme subunit 1 (SAE1) promotes the malignancy of MM. Through proteome microarray analysis, SAE1 was identified as a potential target for bioactive colcemid or its derivative colchicine. Elevated levels of SAE1 were associated with poor clinical survival and increased MM proliferation in vitro and in vivo. Additionally, SAE1 directly SUMOylated and upregulated the total protein expression of p27, leading to LLPS-mediated nuclear export of p27. Our study also demonstrated the involvement of SAE1 in other types of cancer cells, and provided the first monomer crystal structure of SAE1 and its key binding model with colchicine. Colchicine also showed promising results in the Patient-Derived Tumor Xenograft (PDX) model. Furthermore, a controlled clinical trial with 56 MM patients demonstrated the clinical efficacy of colchicine. Our findings reveal a novel mechanism by which tumor cells evade p27-induced cellular growth arrest through p27 SUMOylation-mediated nuclear export. SAE1 may serve as a promising therapeutic target, and colchicine may be a potential treatment option for multiple types of cancer in clinical settings.

Objective To investigate the relationship between aspartate aminotransferase-platelet ratio index(APRI)and hepatocellular carcinoma(HCC)recurrence after radiofrequency ablation(RFA),and to construct a nomogram model for predicting the prognosis.Methods The clinical data of a total of 204 patients,whose initial diagnosis was HCC and received RFA at the Wujin Hospital Affiliated to Jiangsu University of China between January 2017 and December 2020,were retrospectively analyzed.The optimal cut-off value of APRI was determined using receiver operating characteristic(ROC)curve.Kaplan-Meier curves were plotted to estimate the recurrence-free survival(RFS)of high-APRI group patients and low-APRI group patients.The independent predictors of HCC recurrence after RFA were identified by using univariate and multivariate Cox regression analysis,and significant variables were selected to construct a nomogram model.The predictive ability of the nomogram model for HCC recurrence was evaluated by the consistency index(C-index)and calibration curves.Results The incidence of HCC recurrence after RFA was 57.4%(117/204),the optimal cut-off value of APRI for predicting HCC recurrence was 0.501,and the area under curve(AUC)value was 0.678(95%CI=0.603-0.752).High-APRI group(≥0.501)had 121 patients and low-APRI group(＜0.501)had 83 patients.High APRI index was significantly correlated with low RFS(χ2=12.929,P＜0.01).The univariate and multivariate Cox regression analysis revealed that the number of tumors(HR=1.541,95%CI=1.039-2.286,P=0.031),maximum tumor diameter(HR=1.461,95%CI=1.011-2.112,P=0.044),serum AFP level(HR=2.286,95%CI=1.576-3.318,P＜0.01)and APRI index(HR=1.873,95%CI=1.257-2.790,P=0.002)were the independent risk factors for HCC recurrence.Based on the above four variables,a nomogram model for predicting HCC recurrence after RFA was constructed,the C-index was 0.769(95%CI=0.676-0.862),and the AUC values for 1-,2-,and 3-year RFS prediction were 0.707,0.719,and 0.707,respectively.The calibration curves showed that a good consistency existed between the predicted probability and actual probability.Conclusion The nomogram model based on APRI and tumor biological characteristics has an excellent predictive ability for HCC recurrence after RFA.(J Intervent Radiol,2024,32:38-43)

Objective Verify the improvement effect of rhomboid intercostal and sub-serratus plane block on the quality of early postoperative recovery in patients undergoing thoracoscopic radical resection of lung cancer;Comparison of the differences in the effect of regional block at different timing on improving the quality of early postoperative recovery.Methods A total of 75 patients,aged 18 to 75 years,with ASA gradeⅠ-Ⅱ,who were scheduled to undergo thoracoscopic radical resection of lung cancer from January 2022 to January 2023 were selected.Randomly divided into three groups:blank control group(Group C),preoperative block group(PR group),and postoperative block group(PO group).The PR group and the PO group received ultrasound guided rhomboid intercostal and sub-serratus plane block in the preoperative anesthesia preparation room and postoperative anesthesia recovery room,respectively,with a dosage of 0.375％ropivacaine 30ml.Evaluate the postoperative recovery quality of patients at 24 and 48 hours using the postoperative recovery quality rating scale(QoR-40)scoring scale.Record numeric rating scale(NRS)pain scores in resting and active states at 0.5h,1h,2h,4h,8h,12h,24h,and 48h after surgery.Record the consumption of opioid drugs during and after surgery,the effective number of postoperative patient-controlled intravenous analgesia(PCIA)compressions,and the incidence of nausea and vomiting.Results Compared with Group C,the consumption of opioids during surgery in the PR group was significantly reduced.The QoR-40 score at 24 hours after surgery was significantly higher in the PR and PO groups.Significant reduction in NRS scores between 1-8 hours of rest and 1-12 hours of activity after surgery,and the effective times of PCIA compressions and opioid consumption were significantly reduced(P<0.05).Compared with the PR group,the PO group consumed more opioids during surgery and had a higher NRS score at 0.5 hours after surgery(P<0.05).There was no significant difference in postoperative QoR-40 scores,PCIA effective compressions,and opioid consumption;There was no statistically significant difference in the incidence of postoperative nausea and vomiting among the three groups.Conclusion Rhomboid intercostal and sub-serratus plane block can improve the early recovery quality of patients undergoing thoracoscopic radical resection of lung cancer,reduce the postoperative pain level of patients,and reduce the amount of opioids used in perioperative period,and its effectiveness has nothing to do with the blocking time.

Objective By analyzing the means of donor maintenance from the perspective of intensive care medicine,the difference of clinical indicators before and after donor treatment is obtained,summarizing the treatment experience and effect of clinical maintenance of donor donors,and providing more clinical evidence for the maintenance and treatment of organ donation donors.Methods A retrospective analysis was performed on 76 organ donors collected from the Department of Intensive Care Medicine,Army Medical Center,Chinese People's Liberation Army from January 2014 to December 2021,collected donor maintenance treatment,including mechanical ventilation,continuous renal replacement therapy(CRRT)treatment,enteral nutrition and parenteral nutrition,enteral and parenteral nutrition,plasma exchange,at the same time,the paired t test was used to compare the organ function before and after treatment.Results The lung,liver and kidney of 76 donors were evaluated before and after treatment to determine the number of eligible donors.The difference between the number of eligible donors of kidney and liver before and after treatment was statistically significant(P<0.05).There was no significant difference in lung evaluation(P>0.05).Conclusion Timely and effective organ support therapy for organ transplantation donors is beneficial to the recovery of organ function and improve the utilization rate of organ.

Objective To investigate the risk factors for unplanned readmission within 30 days after discharge in cirrhotic patients with esophagogastric variceal bleeding undergoing transjugular intrahepatic portosystemic shunt(TIPS),and to construct a nomogram predictive model.Methods A total of 241 cirrhotic patients who underwent TIPS due to esophagogastric variceal bleeding in Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2020 to June 2023 were enrolled as subjects,and unplanned readmission within 30 days was analyzed.According to the presence or absence of unplanned readmission,they were divided into readmission group with 36 patients and non-readmission group with 198 patients,and related clinical data were collected from all patients.The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.A logistic regression analysis was used to identify independent risk factors for unplanned readmission.A nomogram prediction model was constructed,and the receiver operating characteristic(ROC)curve was plotted to assess its discriminatory ability for unplanned readmission;the calibration curve was plotted to evaluate the consistency of the nomogram model in predicting unplanned readmission;the ResourceSelection package of R language was used for the Hosmer-Lemeshow goodness-of-fit test to evaluate the degree of fitting of the mode;the decision curve analysis was used to investigate the practicality of the model.Results Age(odds ratio[OR]=2.664,95%confidence interval[CI]:1.139-6.233,P<0.05),CTP score(OR=1.655,95%CI:1.098-2.495,P<0.05),and blood ammonia(OR=1.032,95%CI:1.016-1.048,P<0.05)were independent risk factors for unplanned readmission within 30 days after discharge in the patients undergoing TIPS.The multivariate analysis showed that for the nomogram predictive model constructed in this study,repeated sampling for 1 000 times using the Bootstrap method was performed for internal validation,and the area under the ROC curve was 0.773,which was significantly higher than that of age(0.582),CTP score(0.675),and blood ammonia(0.641).The calibration curve showed good consistency between the probability of unplanned readmission predicted by the nomogram model and the actual probability,and the Hosmer-Lemeshow goodness-of-fit test showed good degree of fitting(c2=5.647 3,P=0.686 7).Conclusion Age,CTP score,and blood ammonia are independent risk factors for unplanned readmission within 30 days after TIPS,and the nomogram prediction model constructed based on these factors can help to predict the risk of unplanned readmission in TIPS patients and provide an accurate decision-making basis for early prevention.

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 epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

From October 2021 to February 2023, we retrospectively analyzed the clinical and laboratory data of six patients (three male and three female, median age: 54 years, age range: 29-73 years) with mast cell leukemia (MCL) diagnosed in the First Affiliated Hospital of Soochow University (The Mastocytosis Collaborative Network of China). All patients had acute MCL, with at least one C-finding present. The main clinical presentations were hypoalbuminemia ( n=4), fatigue ( n=3), fever ( n=2), abdominal discomfort ( n=2), osteolytic lesions ( n=2), dizziness ( n=1), skin flushing ( n=1), and weight loss ( n=1). Splenomegaly and lymphadenopathy were noted in six and three patients, respectively. Six patients were strongly positive for CD117, five were positive for CD30 and CD25, and four were positive for CD2. Four patients had a normal karyotype and two patients had an abnormal karyotype. Gene mutations were detected in 4/6 cases. The median serum tryptase level was 24.9 (range: 20.1-171.9) μg/L. Two patients were treated with venetoclax and azacitidine for induction (one patient achieved partial remission by combination with afatinib, while there was no remission after combination with dasatinib in the other patient). Two patients did not achieve complete remission despite treatment with cladribine and imatinib, respectively. One patient treated with interferon combined with glucocorticoids was lost to follow-up, and one patient abandoned treatment. The follow-up time ranged from 1.1 to 21.7 months. Three patients died and two survived. Overall, MCL is a rare subtype of systemic mastocytosis with heterogeneous clinical course, and these patients have poor outcome. A better understanding of the clinical characteristics, treatment, and prognosis of MCL is urgently needed.
