Objective:To investigate the effect of circulating plasma cell(CPC)on the prognosis of multiple myeloma(MM),and to es-tablish and validate a modified CPC-RISS staging system based on CPC and RISS.Methods:A retrospective analysis was performed for the clinical data of 639 treatment-na?ve patients with MM who were treated in Department of Hematology,Xijing Hospital,from January 2006 to June 2023.Peripheral blood smear was used to calculate the percentage of CPC in patients,and the impact of CPC and other related factors on the prognosis of MM patients was analyzed.A CPC-RISS staging system was established based on RISS stage and the percentage of CPC,and the differences in survival and prognosis were analyzed between patients with different stages.Results:Compared with the patients without CPC,detectable CPC was significantly associated with various high-risk factors for MM,and the MM patients with CPC had a lower complete remission rate and shorter overall survival time and progression-free survival time.The modified CPC-RISS staging system was used to classify the patients with MM into four stages,and there were significant differences in median survival time and progression-free survival time between the patients with different stages of MM.Conclusion:The MM pa-tients with the presence of CPC exhibit more aggressive features,worse response to treatment,and a reduction in long-term survival rate.The modified CPC-RISS staging system can effectively predict the prognosis of treatment-na?ve MM patients.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Background and Aims:Papillary thyroid carcinoma(PTC)is the most common endocrine malignancy in China,with cervical lymph node metastasis being a frequent and critical clinical feature that directly affects patient prognosis and recurrence risk.In recent years,with the rapid increase in the prevalence of overweight and obesity in China,the role of body mass index(BMI)in various tumors has attracted growing attention.This study aimed to investigate the association between overweight and cervical LNM in PTC,analyze sex-specific differences and influencing factors,and provide evidence for precise clinical management.Methods:A retrospective analysis was conducted on the clinicopathologic data of 1 445 patients with classical PTC treated at Xiangya Hospital of Central South University between August 2021 and June 2022.Patients were divided into groups based on the presence or absence of lymph node metastasis.Restricted cubic spline analysis explored the nonlinear relationship between BMI and lymph node metastasis risk.Univariate and multivariate Logistic regression analyses were applied to identify independent risk factors.Furthermore,sex-stratified analysis was performed among overweight patients(BMI≥24 kg/m2)to determine sex-specific risk factors for lymph node metastasis.Results:Among all patients,716(49.6%)had lymph node metastasis.Univariate analysis showed that BMI,sex,age,tumor diameter,multifocality,and extrathyroidal extension were significantly associated with cervical lymph node metastasis in PTC patients(all P<0.05).A nonlinear positive correlation was observed between BMI and lymph node metastasis risk,which was more pronounced in male patients.Additionally,BMI was positively correlated with triglyceride levels and negatively correlated with high-density lipoprotein cholesterol.Sex-stratified analysis revealed that in overweight male patients,younger age(OR=0.954),larger tumor diameter(OR=1.085),and multifocality(OR=2.776)were independent risk factors for LNM;in overweight female patients,younger age(OR=0.943)and larger tumor diameter(OR=1.074)were the main influencing factors.Conclusion:Overweight is closely associated with cervical lymph node metastasis in PTC,and the high-risk factors for LNM differ between male and female overweight patients.Young age,larger tumor size,and multifocality in overweight males,and young age and larger tumors in overweight females indicate a higher risk of metastasis.It is recommended that high-risk populations receive enhanced preoperative evaluation and individualized lymph node dissection strategies to achieve precise treatment and improved risk control.

Objective:To evaluate the safety and effectiveness of fuzuloparib for the treatment of ovarian epithelial cancer patients in the real world setting.Methods:A retrospective analysis was conducted on the baseline data of 4 620 ovarian cancer patients who had received fuzuloparib monotherapy or combination therapy. Another 224 ovarian cancer patients who were willing to receive fuzuloparib monotherapy or combination therapy were prospectively enrolled, and their baseline characteristics, drug effectiveness, and safety data were analyzed.Results:(1) Among the 4 620 patients in the retrospective cohort, the median age of patients was 60 years; tumor types: 89.8% (4 149/4 620) had ovarian cancer. Among patients with clearly documented information, the vast majority had a histological type of serous carcinoma (82.9%, 3 770/4 546) and International Federation of Gynecology and Obstetrics (FIGO) staging of Ⅲ-Ⅳ (90.9%, 1 537/1 691). (2) Among the 224 patients in the prospective cohort, the median age of patients was 57 years; tumor types: 83.9% (188/224) had ovarian cancer. Among patients with clearly documented records, the predominant pathologic type was serous carcinoma (91.9%, 193/210), and FIGO stage was Ⅲ-Ⅳ in 79.9% (139/174). (3) Among the 224 prospective patients: 84 patients received first-line fluzoparib maintenance therapy, 92 patients received fluzoparib maintenance therapy after platinum-sensitive recurrence, 23 patients received direct fluzoparib treatment after platinum-sensitive recurrence, 19 patients received direct fluzoparib treatment after platinum-resistant recurrence. The median follow-up durations were 8.5, 8.7, 7.9, and 6.7 months, respectively. The median durations of fluzoparib treatment were 6.7, 4.8, 3.1, and 1.9 months, respectively. The median progression-free survival (PFS) times were not reached during follow-up, 12.6 months, not reached during follow-up, and 4.8 months, respectively. The 1-year PFS rates were 84.1%, 55.0%, 69.8%, and 45.5%, respectively. The remaining 6 patients received other fluzoparib regimens. (4) Among the 224 patients in the prospective dataset, 205 had safety data recorded. Of these, 127 patients (62.0%, 127/205) experienced treatment-related adverse events, with common events including anemia (24.4%, 50/205), thrombocytopenia (21.0%, 43/205), and leukopenia (19.5%, 40/205). Among the 205 patients, 43 (21.0%, 43/205) experienced grade 3 or higher treatment-related adverse events, with common events including anemia (8.3%, 17/205) and thrombocytopenia (8.3%, 17/205).Conclusions:The effectiveness of fuzuloparib in clinical application is generally consistent with other drugs in the same class, with good safety. This study provids new clinical evidence for the treatment of ovarian cancer with fuzuloparib.

Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Peptide-based radiopharmaceuticals targeting integrin α5β1 show promise for precise tumor diagnosis and treatment. However, current peptide-based radioligands that target α5β1 demonstrate inadequate in vivo performance owing to limited tumor retention. The use of PEGylation to enhance the tumor retention of radiopharmaceuticals by prolonging blood circulation time poses a risk of increased blood toxicity. Therefore, a PEGylation strategy that boosts tumor retention while minimizing blood circulation time is urgently needed. Here, we developed a PEGylation-enabled peptide multidisplay platform (PEGibody) for PR_b, an α5β1 targeting peptide. PEGibody generation involved PEGylation and self-assembly. [⁶⁴Cu]QM-2303 PEGibodies displayed spherical nanoparticles ranging from 100 to 200 nm in diameter. Compared with non-PEGylated radioligands, [⁶⁴Cu]QM-2303 demonstrated enhanced tumor retention time due to increased binding affinity and stability. Importantly, the biodistribution analysis confirmed rapid clearance of [⁶⁴Cu]QM-2303 from the bloodstream. Administration of a single dose of [¹⁷⁷Lu]QM-2303 led to robust antitumor efficacy. Furthermore, [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 exhibited low hematological and organ toxicity in both healthy and tumor-bearing mice. Therefore, this study presents a PEGibody-based radiotheranostic approach that enhances tumor retention time and provides long-lasting antitumor effects without prolonging blood circulation lifetime. The PEGibody-based radiopharmaceutical [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 shows great potential for positron emission tomography imaging-guided targeted radionuclide therapy for α5β1-overexpressing tumors.

The activation proteins released by fibroblasts in the tumor microenvironment regulate tumor growth, migration, and treatment response, thereby influencing tumor progression and therapeutic outcomes. Owing to the proliferation and metastasis of tumors, fibroblast activation protein (FAP) is typically highly expressed in the tumor stroma, whereas it is nearly absent in adult normal tissues and benign lesions, making it an attractive target for precision medicine. Radiolabeled agents targeting FAP have the potential for targeted cancer diagnosis and therapy. This comprehensive review aims to describe the evolution of FAPI-based radiopharmaceuticals and their structural optimization. Within its scope, this review summarizes the advances in the use of radiolabeled small molecule inhibitors for tumor imaging and therapy as well as the modification strategies for FAPIs, combined with insights from structure-activity relationships and clinical studies, providing a valuable perspective for radiopharmaceutical clinical development and application.

Triple-negative breast cancer is therapeutically challenging due to the low expression of tumor markers and 'cold' tumor immunosuppressive microenvironment. Here, we present a dual-targeting peptide-drug conjugate (PDC) for tumor inhibition. Our PDC efficiently and selectively delivers cytotoxic Monomethyl Auristatin E (MMAE) into tumor cells via C-X-C chemokine receptor type 4 (CXCR4) and folate receptor 1 (FOLR1) for synergistic inhibition of growth and metastasis. Our results show that the dual-targeting PDC has potent antitumor activity in cultured human cells and several murine transplanted tumor models without apparent toxicity. The combination of dual-targeting PDC and radiotherapy modulates the tumor immunosuppressive microenvironment by increasing CD8⁺ T cell infiltration and attenuating the proportion of myeloid-derived suppressor and regulatory T cells. Therefore, our dual-targeting PDC represents a promising new strategy for cancer therapy that rebalances the immune system and promotes tumor regression.

In October 2024, a 36-year-old female patient with botulinum toxin type A intoxication for 15d was admitted to the Department of Neurology of Northern Jiangsu People’s Hospital. Although type A botulinum antitoxin (BAT) therapy remained effective, the patient developed a serum sickness-like reaction (SSLR) on day 4 of treatment after receiving eight consecutive desensitizing intramuscular injections of BAT. After stopping the injection of the drug and giving intravenous dexamethasone, the patient’s symptoms improved. On the 6th day after stopping the injection of botulinum antitoxin type A, the patient was followed up in the outpatient clinic and the skin symptoms had almost disappeared. This article analyzed the patient’s medical records and explored the association between BAT and SSLR, suggesting that medical personnel should be alert to the risk of adverse reactions when applying antitoxin therapy, and that they should identify and intervene in a timely manner in order to ensure the safety of the medication and therapeutic efficacy of the patients.
