Objective:To evaluate the safety of neoadjuvant therapy with pembrolizumab combined with 5-fluorouracil (5-FU) and cisplatin in patients with advanced temporal bone squamous cell carcinoma (TBSCC), and its impact on tumor response rate and disease-free survival (DFS).Methods:This prospective, single-arm, open-label clinical study enrolled patients with advanced (Stage Ⅲ/Ⅳ) TBSCC from Sun Yat-sen Memorial Hospital. Patients received 2-3 cycles of neoadjuvant therapy with pembrolizumab, 5-FU, and cisplatin, followed by definitive surgery. Postoperatively, patients received 6 cycles of pembrolizumab combined with radiotherapy. The primary endpoint was the 2-year disease-free survival (DFS) rate. Secondary endpoints included objective response rate (ORR) and safety indicators. Survival analysis was performed using the Kaplan-Meier method. Adverse events (AE) were assessed using the National Cancer Institute′s Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Statistical analyses were conducted using SPSS software, version 22.0.Results:From August 2021 to April 2024, 16 patients with advanced TBSCC were enrolled (13 males and 3 females), with a median age of 54 years and a median follow-up time of 2.32 years. Following neoadjuvant therapy, the objective response rate (ORR) was 64.3% (9/14), and the disease control rate (DCR) was 92.9% (13/14). The 2-year DFS rate was 86.6%. Common treatment-related adverse events (TRAE) included leukopenia (56.3%, 9/16), nausea and vomiting (50.0%, 8/16), diarrhea, oral mucositis, and elevated liver function tests (25.0%, 4/16). One patient (6.25%) experienced a grade 3 adverse event.Conclusion:Neoadjuvant pembrolizumab-chemotherapy significantly enhances objective response rate and disease-free survival in advanced TBSCC.

Plant-derived bioactive peptides have become a research hotspot in the fields of food and medicine due to their high source safety,easy absorption and utilization by the human body,and potential edible and medicinal value.Bioactive peptides can be classified into antihypertensive,hypoglycemic,hypolipidemic,anticancer,antioxidant,antimicrobial,and anti-inflammatory peptides according to their functions.Among these,antihypertensive,hypoglycemic,and hypolipidemic peptides are collectively referred to as cardiovascular active peptides,which can be used for the treatment and prevention of cardiovascular diseases and have an important role in the development of modem biomedicine.This review focused on the preparation methods,separation,purification,and identification techniques of bioactive peptides,as well as their mechanisms of action and applications in regulating cardiovascular diseases,aiming to provide a reference for further development and application of plant-derived cardiovascular peptides.

Objective:To explore drug detoxification motivation in methamphetamine-dependent female youth and its relationship with time perspective,perceived social support and emotion regulation strategies.Methods:To-tally 200 methamphetamine-dependent female youths under compulsory isolation were assessed with the Drug De-toxification Motivation Scale,Zimbardo Time Perspective Inventory-Chinese(ZTPI-C),Emotion Regulation Scale(ERS),and Perceived Social Support Scale(PSSS).Results:Multiple linear regression analysis showed that drug detoxification motivation scores were positively correlated with the scores of ERS reevaluation and expression inhi-bition,PSSS family support scores and level of education(β=0.24,0.16,0.20,0.16).Conclusion:Time perspec-tive,perceived social support and emotion regulation strategies are closely related to drug detoxification motivation in methamphetamine-dependent female youth.

Objective:To investigate the clinical features and risk factors of second asparaginase-associated pancreatitis (AAP) in children with acute lymphoblastic leukemia (ALL).Methods:In this case-control study, the clinical data of ALL children who were diagnosed with pancreatitis and received asparaginase chemotherapy at Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine from November 2013 to November 2023 were retrospectively analyzed.Multivariate Logistic regression was used to determine independent risk factors for the occurrence of second AAP.Results:A total of 78 children with AAP were included, of whom 32 were re-exposed to asparaginase.Ten of the 32 cases (31.25%) suffered second AAP, and they were rated at intermediate risk, with an age of (8.26±0.87) years.The number of asparaginase re-exposures before second AAP was (2.10±0.99) times.Second AAP developed during the intensification period in 2 cases and during the re-induction period in 8 cases.There were 3 cases (30.00%) of Grade 1 pancreatitis and 7 cases (70.00%) of Grade 2 pancreatitis.No patient died of second AAP.Two patients (20.00%) experienced AAP-related long-term complications, including chronic pancreatitis and insulin-dependent diabetes mellitus.After 2 children with no clinical data related to the first AAP were excluded, 30 re-exposed children were divided into a control group (22 cases) and a case group (8 cases) according to the presence or absence of second AAP.The univariate analysis showed that there were significant differences in activated partial thromboplastin time (APTT)[(29.80±5.25) s vs.(38.47±1.42) s, t=-0.45, P=0.023] and total bilirubin (TBIL)[18.40 (11.00, 25.53) μmol/L vs.24.30 (19.93, 46.48) μmol/L, Z=-0.32, P=0.020] between the 2 groups.The further multivariate Logistic regression analysis showed that after adjusting for age and immunophenotype, TBIL ( HR=1.115, P=0.048) was an independent risk factor for second AAP.Comparisons of the prognosis revealed that there were no significant differences in long-term complications ( P=0.168) and final survival ( P=0.716) between children with only once AAP (68 cases) and those with second AAP (10 cases). Conclusions:Second AAP mostly occurs after the second dose of asparaginase, and the re-induction period is the peak period of incidence of second AAP.Hyperbilirubinemia may be a risk factor of second AAP.Compared with once AAP, second AAP does not increase the mortality and the incidence of AAP-related long-term complications.
