Objective To explore the correlation between changes in spleen volume and stiffness before and after transjugular intrahepatic portosystemic shunt (TIPS) and the occurrence of hepatic encephalopathy. Methods A retrospective study was conducted on 104 patients who underwent TIPS in the Department of Interventional Therapy, Zhongshan Hospital, Fudan University, from January 1, 2023 to July 30, 2024. Spleen volume and stiffness were measured before and after surgery. Patients were divided into the overt hepatic encephalopathy (OHE) group and the non-OHE group. Univariate and multivariate logistic regression analyses were used to identify factors correlated with OHE after TIPS. The predictive values of the related factors of OHE were evaluated using receiver operating characteristic (ROC) curves. Results OHE occurred in 34 patients (32.69%). Compared with the non-OHE group, the OHE group had a smaller percentage reduction in spleen volume after TIPS (P＜0.001), but there was no statistically significant difference in the percentage reduction in spleen stiffness between the two groups. Multivariate logistic regression analysis revealed that the percentage reduction in spleen volume was correlated with postoperative OHE (OR＝0.90, P＜0.001). ROC analysis showed that the area under the curve (AUC) for spleen volume reduction percentage in predicting postoperative OHE was 0.773, superior to spontaneous portosystemic shunt (SPSS; Z＝2.088, P＝0.037). Conclusions Reduction in spleen volume after TIPS may be a protective factor against hepatic encephalopathy, while changes in spleen stiffness were not found to be correlated with its occurrence.

Aerosol removal using flame-retardant atomized fixatives, as a major means of aerosol control, has achieved remarkable results in the field of nuclear facility decommissioning and decontamination. Traditional atomized fixatives for aerosol removal have deficiencies in high-temperature resistance and flame retardancy, rendering them inadequate for operational scenarios involving high temperatures and flammability encountered during nuclear decommissioning. This paper investigates the current development of flame-retardant atomized fixatives for aerosol removal both domestically and internationally and presents a preliminary exploration of this technology. The experiments showed that atomized fixatives modified with flame-retardant properties not only maintained excellent aerosol capture efficiency, but also exhibited significantly improved flame-retardant performance. This confirmed the technical feasibility of the proposed approach. Finally, suggestions and reflections are proposed for the development of this technology and its application in nuclear facility decommissioning.

Objective: To investigate the status and associated factors of sports supplement usage among grade 9 students, so as to provide a scientific basis for targeted supervision and health education regarding sports supplement usage among junior high school students. Methods: From June to September 2025, a stratified cluster random sampling method was used to select 2 261 grade 9 students from 10 provinces (autonomous regions, municipalities) in China. A questionnaire survey was conducted on their sports supplement usage and related factors. The Chi square test was used to compare the usage rates of sports supplements among different groups of students, and binary Logistic regression analysis was employed to investigate the related factors of sports supplement usage among grade 9 students. Results: Totally 59.7% of the grade 9 students used sports supplements. The usage rate (62.5%) was higher among boys than girls (56.3%), higher among students from rural areas and towns/counties (66.5%, 66.2%) than those from urban districts (52.9%), higher among boarding students (65.2%) than non resident students (54.3%), higher among students whose parents occupations were businessmen and workers (fathers: 65.0%, 63.7%; mothers: 63.6%, 61.1%) than those whose parents were farmers and civil servants (fathers: 57.5%, 54.1%; mothers: 58.8%, 55.7%), higher among students with a monthly family income of 5 000- 10 000 yuan (66.3%) than those in other income groups, and higher among students in the high score zone for the entrance physical examination to senior high school (67.7%) than those in the medium and low score zones ( 56.3% , 56.5%) ( χ 2=8.99, 42.21, 27.98, 20.55, 8.20, 22.74, 24.70, respectively, all P <0.05). Binary Logistic regression analysis showed that boys ( OR =1.26), those from rural areas ( OR =1.59), boarding students ( OR =1.36), those with a monthly family income of 5 000- 10 000 yuan ( OR =1.41), and those in the high score zone for entrance physical examination to senior high school ( OR =1.34) were more likely to use sports supplements during the entrance physical examination to senior high school; the probability of sports supplement usage was lower among students whose fathers were civil servants ( OR =0.74) (all P <0.05). Conclusions The usage of sports supplements is relatively common among grade 9 students. Intervention measures should be targeted at specific populations to reduce the risk of misuse.

This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material， covering aspects such as nomenclature， origin， geographical distribution， harvesting and processing methods， quality assessment， therapeutic effects and indications， by consulting ancient herbal texts， medical compendia， and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty， with Zhuli being the standard name used throughout history， alongside aliases like Zhuzhi， Zhuyou and Huoquan. Historically， the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis（Danzhu）， although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou（present-day Chengdu and surrounding areas in Sichuan） and the Wuling region（between present-day Hunan， Guangdong， Guangxi and Jiangxi provinces）， while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally， Bambusae Succus was harvested from bamboo that had grown for exactly one year， today， it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation， whereas modern industrial production employs dry distillation， reflux extraction， and percolation. In terms of quality evaluation， ancient texts considered a sweet taste to be superior， while today， clarity and transparency are prioritized. Historically， Bambusae Succus was characterized as sweet and cold nature， targeting the lung and stomach meridians， with uses evolving from clearing heat and resolving phlegm to nourishing Yin， moistening dryness， and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet， bitter， and cold in nature， affecting the heart， liver， and lung meridians， with functions including clearing heat， resolving phlegm， and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion， lung heat with phlegm congestion， convulsions， epilepsy， excessive phlegm in febrile diseases， high fever with thirst， irritability during pregnancy， and tetanus， with more clearly defined applications. Based on the results of the research， it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus， the one-year-old Phyllostachys nigra var. Henonis， which has been highly praised throughout history， should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore， in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste， and reasonable modern quality control standards should be established.

Objective: To examine the application of multi-disciplinary treatment (MDT) in the diagnosis and management of recurrence and metastasis of adenoid cystic carcinoma (ACC) of the palate, as well as the treatment of concurrent massive palatal bleeding. This article aimed to provide references for the diagnosis and treatment of patients with advanced oral cancer, along with strategies for managing massive hemorrhage. Methods: This article reported on the MDT process for a patient diagnosed with ACC of the left upper palate, who experienced skull base recurrence and lung metastasis following surgery and radiotherapy. The case was further complicated by massive palatal hemorrhage. Additionally, the article analyzed patients with ACC recurrence and significant hemorrhage in the context of relevant literature. The patient was a 36-year-old female with ACC located in the left palate, initially diagnosed at clinical stage T3N0M0 in 2013. She underwent an extensive resection of the palatal lesion, followed by radioactive 125I seed implantation, which was guided by a radiotherapy planning system (TPS) and a digital guide. The patient was monitored for four years post-surgery, during which no signs of tumor recurrence were observed. However, at the fifth year of follow-up, the patient developed recurrence with lung metastasis, classified as T4N0M1. Following a multidisciplinary consultation involving the oral and maxillofacial surgery, radiotherapy, medical oncology, and thoracic surgery, the patient underwent a procedure comprising left subtotal maxillary resection, autologous free flap transplantation, and thoracoscopic resection of pulmonary metastases. After surgery, the patient received 60 Gy of radiotherapy and was orally administered Anlotinib hydrochloride capsules to suppress tumor growth. After 31 months of follow-up, the patient reported experiencing slight bleeding in the mouth. A craniomaxillofacial CT scan revealed that the tumor had grown aggressively, resulting in destruction of the skull base. Consequently, the patient was admitted to the hospital. On the second day of admission, she experienced a sudden episode of oral bleeding. Despite the application of pressure, the bleeding continued unabated. An emergency tracheotomy was performed to relieve the obstruction of the patient’s respiratory tract, and a red blood cell suspension was transfused to address the hemorrhagic shock. Following an urgent consultation with the vascular interventional surgery department, super-selective embolization was promptly employed to effectively halt the bleeding and achieve rapid vascular occlusion. An individualized treatment plan was developed under MDT, incorporating postoperative radiotherapy, targeted therapies, and immunotherapy to manage the tumor. Results: Through the MDT model, the patient successfully achieved emergency hemostasis, and normal vital signs were restored. With the addition of radiotherapy and immune-targeted drug treatment, tumor progression was effectively controlled, leading to an improved quality of life for the patient, who successfully survived for 129 months with the tumor by July 2024. A review of the relevant literature indicated that MDT offered significant advantages in the management of adenoid cystic carcinoma. In selecting surgical methods, the team administering MDT could comprehensively evaluate factors such as the patient’s age, physical condition, tumor location, size, and extent of invasion to develop a personalized treatment plan. Radical surgical resection was a common treatment option for ACC. Postoperative tissue defects could be restored to their corresponding functions and aesthetic appearance through autologous tissue reconstruction, utilizing techniques such as peroneal myocutaneous flaps or iliac myocutaneous flaps, or by the implantation of artificial materials. In complex cases involving positive margins, recurrence, and metastasis, the MDT model employed interdisciplinary collaboration to devise a comprehensive treatment plan that may have included re-operation, radiotherapy, and chemotherapy, with the aim of minimizing the risk of ACC recurrence and controlling distant metastasis. Massive bleeding resulting from advanced oral cancer presented a complex medical challenge, influenced by various risk factors such as tumor type, metastasis, treatment options, and the patient’s overall condition. Early identification of bleeding risks, along with strategies to mitigate the adverse effects of bleeding on disease progression—through supportive care, medical treatment, surgical intervention, and interventional therapy—could significantly enhance patients’ quality of life. Conclusion The MDT model can provide comprehensive, precise, and personalized treatment plans for patients with advanced oral cancer and massive hemorrhage and improve the effectiveness of treatment strategies.

With the rapid development of mobile internet technology, mobile health application (mHealth APP) are increasingly widely used in the field of health management and have been proven to play an important role in the management of chronic diseases. Solid organ transplant recipients face complex health management needs after surgery, including postoperative follow-up, medication management, prevention and treatment of complications and comorbidities, and lifestyle adjustment. mHealth APP can provide solid organ transplant recipients with convenient self-management tools. Although some progress has been made in this field, there are still many challenges, such as insufficient user experience, technological dependence, and data security risks. Therefore, this article discusses the development process, main functions and current application status of mHealth APP, and analyzes its advantages in improving the self-management ability of solid organ transplant recipients, promoting doctor-patient communication and reducing the incidence of complications. At the same time, based on the practical experience of author’s team in developing the “TransMate” mHealth APP, we propose the directions that mHealth APPs should focus on in the future, in order to provide more effective support and services for the health management of solid organ transplant recipients.

Objective To observe the value of multi-sequence magnetic resonance imaging(MRI)radiomics in predicting the efficacy of concurrent chemoradiotherapy(CCRT)in locally advanced cervical squamous cell carcinoma(CSCC)patients.Methods Clinical data of 100 CSCC patients underwent CCRT treatment were selected.In order to better validate the performance of the model,patients were randomly divided into the training set(70 cases)and the validation set(30 cases)in a 7∶3 ratio.According to the efficacy criteria for solid tumors,patients were divided into the complete response(CR)group(n=16)and the partial response(PR)group(n=14).Examination images of cross-sectional DWI,T2WI and enhanced T1WI were collected from all patients before treatment.ITK-SNAP software package combined with three sequences were used to outline ROI,and the open source software PyRadiomics was used to extract image omics features.For MRI omics features,the minimum redundancy maximum correlation(mRMR)algorithm was used to analyze and screen out the first 30 main features,and then the minimum absolute contraction and selection method(Lasso)based on 10-fold cross-validation was used to reduce dimensionality to screen the non-zero coefficient features.According to the weighting coefficient of Lasso-Logistic regression model in the training set,patient omics labels were calculated.Logistic regression analysis was used to construct a prediction model based on DWI,T2WI and T1WI sequence prediction models and multiple sequenomics labels.Receiver operating characteristic(ROC)curves evaluated the predictive value of each omics model for CCRT treatment in patients with locally advanced CSCC.Results There were 38 cases in the CR group and 32 cases in the PR group in the training set.There were 16 cases in the CR group and 14 cases in the PR group in the validation set.There were no significant differences in patient age,FIGO stage,differentiation degree,maximum lesion diameter and menstrual status between the CR group and the PR group in the training and validation sets.A total of 851 imaging features were extracted from the ROI target area.After the first 30 features were retained by mRMR algorithm,3 CR-related features were selected from the 851 imaging omics features of each individual sequence by Lasso algorithm and 10-fold cross-validation.Eight CR related features were selected from 2 553 features after the combination of the three sequences.ROC curve results showed that in the training set and validation set,the AUC of multiple sequences combined to predict the therapeutic effect of CCRT in patients with locally advanced CSCC was 0.971 and 0.946,respectively,which was higher than that of T1WI,T2WI and DWI single sequence prediction(training set Z=2.683,2.046,2.817,P＜0.05;verification set Z=2.075,2.117,2.005,P＜0.05).Conclusion The multi sequence MRI radiomics model has high predictive value for the efficacy of CCRT treatment in locally advanced CSCC patients.

Complex tumors of the maxillofacial region are difficult and risky to operate due to the complex anatomical structure and the proximity of multiple important neurovascular vessels,which is a great challenge for surgeons.Traditional single-mode imaging often requires physicians to synthesize different image features for analysis,and this kind of detached diagnosis brings great inconvenience to clinical practice.In recent years,with the increasing application of digital technology in the treatment of maxillofacial tumors,it is pos-sible to display the tumor site,invasion range and its relationship with neurovascularity in a more three-dimensional and intuitive way,which greatly reduces the risk of surgery.In this paper,we focus on the clinical application of multimodal medical image fusion technol-ogy in complex maxillofacial tumors and its joint application with digital surgical technologies such as rapid prototyping technology,mixed reality technology,surgical navigation,surgical robotics,artificial intelligence,etc.,to give an overview and outlook.

Objective To investigate the anatomical characteristics of the right top pulmonary vein(RTPV),a rare variant pulmonary vein displayed on chest CT,and its clinical significance in thoracoscopic right lung surgery.Methods The clinical data from 27 patients who underwent thoracoscopic right lung surgery were collected.Of these,24 patients were diagnosed with RTPV by preoperative chest CT.The anatomical characteristics were analyzed in combination with three-dimensional reconstruction.Three cases were diagnosed with RTPV based on preoperative chest CT after abnormal veins behind the intermediate bronchus were identified during surgery.Results Of the 27 patients of RTPV,22 cases drained blood from the posterior segment of the right upper lobe(S2),4 cases drained blood from both the S2 and S6a,and 1 case drained blood from both the S2 and S1a.After crossing behind the intermediate bronchus,13 cases returned blood to the lower pulmonary vein,5 cases returned blood to V6,7 cases returned blood to the left atrium,and 2 cases returned blood to the root of the upper pulmonary vein.The vascular diameter of the RTPV was(5.1±1.7)mm.All 27 patients successfully completed thoracoscopic surgery without massive hemorrhage caused by accidental injury to the PTRV.The intraoperative anatomy corresponded to the preoperative chest CT and three-dimensional reconstruction.The intraoperative bleeding volume was(44.6±43.7)mL,and there was no massive hemorrhage caused by accidental injury to the RTPV.Nine patients underwent right lower lobectomy,and four patients had the RTPV preserved,with no postoperative hemoptysis.Five patients underwent RTPV transection,of which two experienced transient hemoptysis following surgery with no serious complications.Conclusion Chest thin-section CT can be applied to diagnose RTPV.Preoperative identification via CT is crucial to avoid massive hemorrhage resulting from accidental injury during thoracoscopic surgery of the right lung.RTPV can be preserved as appropriate in patients undergoing right lower lobectomy.

Oocyte maturation disorders and fertilization failures are caused by a variety of factors, including complex factors such as chromosomal abnormalities and poor oocyte quality. With the widespread use of high-throughput sequencing technology, more and more genetic mutations have been found to be associated with oocyte maturation and fertilization process in infertile patients. This paper summarizes and discusses 11 key genes ( TRIP13, TBPL2, LHX8, PATL2, TUBB8, CDC20, WEE2, ZP, ASTL, JUNO and CD9) related to oocyte maturation and fertilization-related disorders in females, providing a basis for research on the prevention of diseases associated with oocyte maturation blockage and fertilization failure and the development of targeted therapies.
