Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as ¹³¹I,¹⁷⁷Lu, or ¹⁸F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, ¹⁸F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Oleanolic acid (OA), a pentacyclic triterpenoid, exhibits a broad spectrum of biological activities, including antitumor, antiviral, antibacterial, anti-inflammatory, hepatoprotective, hypoglycemic, and hypolipidemic effects. Since its initial isolation and identification, numerous studies have reported on the structural modifications and pharmacological activities of OA and its derivatives. Despite this, there has been a dearth of comprehensive reviews in the past two decades, leading to challenges in subsequent research on OA. Based on the main biological activities of OA, this paper comprehensively summarized the modification strategies and structure-activity relationships (SARs) of OA and its derivatives to provide valuable reference for future investigations into OA.

Objective:To investigate the clinical efficacy of individualised microvascular decompression (MVD) for trigeminal neuralgia (TN), so as to provide individualised treatment strategies and new thoughts for treatment.Methods:Clinical data of 46 patients who had TN and treated in the Department of Neurosurgery at the First Affiliated Hospital of Anhui Medical University from January 2021 to September 2023 were retrospectively studied. The study consisted of 19 males and 27 females, with an average age of morbidity at (58.3 ± 9.0) years old. Preoperative pain ratings and surgical outcomes were evaluated using the Barrow Neurological Institute (BNI) pain rating scale, and of which 27 patients were rated at BNI grade IV and 19 at grade V before surgery. A posterior trans-sigmoid sinus approach was applied in surgery on all patients, which could be performed in various ways depending on the vascular conditions identified during surgery. Ten patients were treated with microsurgery, 12 with endoscopic surgery and 24 with combined endoscopic surgery and microsurgery. After having identified the responsible vessel(s), a vascular decompression for the affected trigeminal nerve was performed and the nerve decompression was achieved by a polyester pad. Long-term postoperative follow-ups were conducted via telephone interviews or outpatient visits.Results:A total of 46 patients received the microvascular decompression surgery. Among them, 43 cases (93.5%) achieved immediate and complete pain relief of BNI grade I after surgery, and 3 cases (6.5%) achieved partial pain relief of BNI grade Ⅱ. Four patients developed facial numbness and sensory reduction, 2 developed facial paralysis (of House-Brackmann grade Ⅱ of 1 patient and grade Ⅲ of the other), 8 developed pneumocephalus, 4 developed postoperative fever, and 2 developed subcutaneous effusion. After treatment, the pneumocephalus and fever were cured, subcutaneous effusion was disappeared in 1 patient, but remained in the other. The mean follow-up period for the 46 patients was 16.2 (1-33) months. During the follow-up, 2 of the 3 patients of BNI grade Ⅱ immediately after surgery had complete remission to BNI grade Ⅰ and the other had recurrence and aggravation at BNI grade Ⅳ.Conclusion:The complexity of the responsible vessels is one of the important factors to be considered in the microvascular decompression strategy for trigeminal neuralgia. An individualised surgical plan according to a specific vascular condition identified in the surgery, is a best possible or worthiness surgical strategy in the treatment for a TN.

Objective To explore the effect of controlled low central venous pressure(CLCVP)on venous congestion and postoperative acute kidney injury(AKI)in cardiac surgery under cardiopulmonary bypass(CPB).Methods A total of 137 patients scheduled for elective cardiac surgery under general anes-thesia with CPB were selected,including 73 males and 64 females,aged 18 to 70 years,with a BMI of 20 to 28 kg/m2,and ASA physical status Ⅱ or Ⅲ.The patients were randomly assigned into two groups:the controlled low central venous pressure group(group CL,n=68)and the control group(group C,n=69).In group CL,CLCVP was applied by pumping nitroglycerin to reduce CVP to below 10 mmHg after 20 minutes of CPB cessation until the end of surgery.If necessary,norepinephrine was applied to maintain MAP≥65 mmHg.Patients in group C received standardized anesthesia management.Urine samples were collected before anesthesia induction and 12 hours postoperatively to detect the concentration of kidney injury molecule-1(KIM-1).Urine samples were also collected before anesthesia induction and 2 hours postopera-tively to detect the concentration of neutrophil gelatinase-associated lipocalin(NGAL).Cumulative time a-bove 10,12,16,and 20 mmHg and time-weighted average CVP were used to assess venous congestion.The occurrence of postoperative AKI,stage 2 or above AKI,renal replacement therapy(CRRT),postoperative low cardiac output syndrome(LCOS),acute kidney injury following cardiac surgery(AKICS)score when arriving in ICU,in-hospital mortality,ICU stay,and postoperative hospital stay were recorded.Results Compared with group C,the cumulative time of CVP above 10,12,16,and 20 mmHg after CPB in group CL was significantly shorter,and the time-weighted average CVP was significantly lower(P＜0.05).AKI occurred in 9 patients(13.2%)in group CL and 15 patients(21.7%)in group C postoperatively,and there was no significant difference between the two groups.One case(1.5%)of stage 2 or above AKI oc-curred in group CL and 2 patients(2.9%)in group C,with one patient in group C requiring CRRT.Com-pared with group C,the concentrations of KIM-1 at 12 hours postoperatively and NGAL at 2 hours postoper-atively were significantly lower in group CL(P＜0.05).There were no statistically significant differences between the two groups in LCOS,AKICS score,in-hospital mortality,ICU stay,and postoperative hospital stay.Conclusion Controlled low central venous pressure in cardiac surgery under cardiopulmonary bypass can reduce venous congestion and decrease the occurrence of postoperative renal injury,thereby exerting a certain renal protective effect.

Objective:To explore the impact of unpleasant symptoms and their antecedents on the functional performance of patients with chronic obstructive pulmonary disease (COPD) .Methods:From January 2020 to June 2023, convenience sampling was used to select COPD patients admitted to the Respiratory and Intensive Care Unit of Xinxiang Central Hospital as research subjects. The subjects were surveyed using the General Information Questionnaire, Functional Performance Inventory-Short Form (FPI-SF), Memory Symptom Assessment Scale (MSAS), Mishel Uncertainty in Illness Scale (MUIS), Social Support Rating Scale (SSRS), and the General Self-Efficacy Scale (GSES). Global Initiative for Chronic Obstructive Lung Disease (GOLD) grading was used to evaluate subjects' lung function. Pearson correlation was used to explore the correlation between the scores FPI-SF, MSAS, MUIS, SSRS, GSES, and GOLD grading. Structural equation modeling was implemented to explore the impact of unpleasant symptoms and their antecedents on the functional performance of COPD patients.Results:A total of 279 questionnaires were distributed and 276 valid questionnaires were collected, with a valid response rate of 98.92%. Among 276 COPD patients, the scores of FPI-SF, MSAS, MUIS, SSRS, and GSES were (2.08±0.24), (2.08±0.28), (95.41±12.83), (43.94±5.94), and (23.78±4.88), respectively. Functional performance was negatively correlated with unpleasant symptoms, disease uncertainty, and GOLD grading ( r=-0.478, -0.353, -0.574; P<0.05) and positively correlated with social support and self-efficacy ( r=0.451, 0.364; P<0.05). Structural equation modeling showed that GOLD grading, disease uncertainty, and social support indirectly affected functional performance through unpleasant symptoms, while GOLD grading and social support directly affected functional performance, and self-efficacy played a partial mediating role between unpleasant symptoms and functional performance; the above differences were statistically significant ( P<0.05) . Conclusions:The functional performance of COPD patients is poor. Medical and nursing staff can develop comprehensive intervention measures, including physiology, psychology, social environment, and self-efficacy, to improve patients' functional performance.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.
