This case report describes a 68-year-old male patient diagnosed with primary hepatocellular carcinoma (HCC). After receiving Yttrium-90 microsphere selective internal radiation therapy (⁹⁰Y-SIRT), the tumor significantly reduced in size, and tumor markers alpha fetoprotein (AFP) and abnormal prothrombin (PIVKA-Ⅱ) decreased. Postoperative pathological results showed minimal residual tumor cells, indicating that ⁹⁰Y-SIRT has good efficacy and safety in downstaging and conversion of HCC, thereby facilitating subsequent surgical resection.

The implementation of the "Regulations on Organ Donation and Transplantation" (hereinafter referred to as the new "Regulations") and supporting documents has laid a solid foundation for improving the organ donation and transplantation work system in accordance with laws and regulations. In order to better publicize, implement, and carry out the new "Regulations" and supporting documents, and in response to the problems and challenges encountered in actual work, combined with the development of the national human organ donation and transplantation work system and the national work on determination of brain death, this article analyzes and discusses the construction of hospitals' organ donation and transplantation work systems and the systematic multidisciplinary collaboration mechanism for organ donation, as well as several issues that need attention by the ethics committees for organ transplantation. The aim is to provide references for the construction of ethics committees for organ transplantation in China and to promote the continuous and healthy development of China's organ donation and transplantation cause.

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 assess the cost-effectiveness of durvalumab combined with chemotherapy as a first-line treatment for advanced biliary tract cancer from the perspective of the Chinese healthcare system. METHODS Using data from the TOPAZ-1 clinical trial， a three-state Markov model comprising progression-free survival （PFS）， progressive disease （PD） and death was developed， with a cycle length of 21 days and a 10-year time horizon. Patients in the observation group received durvalumab in combination with gemcitabine and cisplatin， whereas those in the control group received placebo plus the same chemotherapy regimen. The evaluation indexes were quality-adjusted life year （QALY） and the incremental cost-effectiveness ratio （ICER）. The willingness-to-pay （WTP） threshold was set at three times the 2024 Chinese per capita gross domestic product （GDP） （287 247 yuan/QALY）. The sensitivity analyses， along with scenario analyses， were performed. RESULTS In the base-case analysis， the ICER of observation group compared to control group was 1 166 344.46 yuan/QALY， far exceeding the WTP threshold， indicating that the regimen was not cost-effective. One-way sensitivity analysis identified the PD state utility， discount rate， cost of durvalumab， and PFS state utility as the main drivers of ICER variation. Probabilistic sensitivity analysis showed that， at the above WTP threshold， the probability of the acceeptance of this regimen was 0， further supporting the robustness of the base-case findings. In the scenario analysis， inclusion of a patient assistance program reduced the ICER to 235 885.16 yuan/ QALY， below the above WTP threshold， suggesting cost-effectiveness under this assistance program. However， when applying a regional WTP threshold set at three times the per capita GDP （158 475 yuan/QALY） of Gansu Province （the province with the lowest GDP in China in 2024）， the ICER remained above the threshold， indicating that the regimen was not cost-effective at the regional level. CONCLUSIONS At current pricing， durvalumab plus chemotherapy as a first-line treatment for advanced biliary tract cancer is not cost-effective in China. Although the introduction of a patient assistance program can substantially reduce the ICER and achieve cost-effectiveness at a WTP threshold set at three times the 2024 per capita GDP of China， due to limited affordability in low-income areas， the program remains not cost-effective.

Objective To investigate an automated pretreatment technology for detecting levels of free silica in workplace dust. Methods An fully automated pretreatment workstation for detecting free silica levels in workplace dust was developed by integrating graphite-controlled digestion temperature, online-controlled dilution of digestion solutions, and filtration endpoint recognition based on monitoring technology, combined with multi-channel synchronous measurements. Results The fully automatic pretreatment workstation was used to digest and filter 14 standard samples of free silica produced by three institutions, and then detected by pyrophosphate method. The result range of high-, medium-, and low-level free silica standard samples detection was 66.5%-84.8%, 40.0%-44.5%, and 2.1%-24.8%, respectively. The mean relative standard deviations were 3.9%, 1.4% and 1.5%. Conclusion The fully automated pretreatment workstation produced results that met relevant requirements. It can effectively replace the manual digestion and filtration steps of the pyrophosphate method to measure free silica levels in workplace dust and enable rapid detection of free silica in dust samples.

Objective To explore the effectiveness of the diffusion of innovation theory in com-bination with multidisciplinary nursing collaboration in intervention for patients with severe pneumonia complicated by heart failure.Methods A total of 120 patients with severe pneumonia complicated by heart failure admitted between April 2021 and April 2024 were enrolled and randomly divided into observation group(n=60)and control group(n=60)using a random black-and-white ball method.The control group received conventional nursing intervention,while the observation group received an intervention model combining the diffusion of innovations theory with multidisciplinary collaboration on top of the conventional nursing.Rehabilitation outcomes(time to control of pulmonary inflammation,time to resolution of cough and expectoration,length of hospital stay)and post-intervention cardiac function[left ventricular ejection fraction(LVEF),left ventricular end-systolic volume(LVESV)]were compared between the two groups.The Minnesota Living with Heart Failure Questionnaire(MLHFQ)was used to assess quality of life,and the Self-Care Heart Failure Index(SCHFI)was used to evaluate self-care behaviors.Complications were compared between the two groups,and cost-effectiveness was analyzed(patient medical expenses and re-hospitalization rates).Results The observation group had shorter time to resolution of cough and expectoration,control of pulmonary inflammation,and length of hospital stay compared with the control group,with statistically significant differences(P＜0.05).After intervention,LVEF increased in both groups compared with pre-intervention lev-els,and was higher in the observation group than in the control group,with a statistically significant difference(P＜0.05);ESV decreased in both groups compared with pre-intervention levels,and was lower in the observation group than in the control group,with a statistically significant difference(P＜0.05).After intervention,physiological,emotional,and social functioning scores in the MLHFQ decreased in both groups compared with pre-intervention levels,and were lower in the ob-servation group than in the control group,with statistically significant differences(P＜0.05).After intervention,scores for self-care maintenance,self-care management,and self-care confidence in the SCHFI increased in both groups,and were higher in the observation group than in the control group,with statistically significant differences(P＜0.05).There was no statistically significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion The combination of the diffusion of innovations theory and multidisciplinary collaboration nursing model can accelerate the rehabilitation process in patients with severe pneumonia complicated by heart fail-ure,improve their quality of life,and effectively enhance their self-care abilities.

Background and objective Lung cancer is the most common type of cancer,accounting for more than half of all cancer cases,with lung adenocarcinoma(LUAD)representing over half of lung cancer patients.Currently,the 5-year survival rate for metastatic LUAD patients remains low and there is an urgent need for new biomarkers as targets for targeted therapy.Go-Ichi-Ni-San 1(GINS1),an important member of the GINS family,is closely related to the occurrence and devel-opment of human malignant tumors.This study aims to explore the role of GINS1 in glycolysis,proliferation,and metastasis of LUAD cells and the related molecular mechanisms.Methods The expression of GINS1 was analysed using bioinformatics between LUAD patients and healthy controls.The expression levels of GINS1 in LUAD and adjacent tissues were detected by immunohistochemistry and Western blot.Western blot and real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)were used to detect the expression of GINS1 in LUAD cell lines A549,SK-LU-1,Calu-3,H1299 and BEAS-2B.Stably knockdown GINS1 in A549 cells and its negative control cell line,as well as stably overexpress GINS1 in H1299 cells and its negative control cell line,were constructed by lentiviral transduction.Colony formation test was used to detect cell proliferation.Scratch test was used to detect cell migration.Transwell test was used to detect cell invasion,and the test kits were used to detect glucose consumption and lactate production.The expression levels of glycolysis-related proteins,Notch signaling pathway proteins and phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/AKT/mTOR)signaling pathway proteins were detected by Western blot.The Notch receptor agonist Jagged1 was added to cells from the shGINS1-A549 group and the Notch receptor inhibitor LY3039478 was added to cells from the GINS1-OE-H1299 group for the regression assay.Results The expression of GINS1 was up-regulated in LUAD patients,tissues and cell lines,and corre-lated with overall survival(P＜0.05).Knockdown of GINS1 significantly inhibited the proliferation,migration and invasion of A549 cells(P＜0.05),while overexpression of GINS1 significantly enhanced the proliferation,migration and invasion of H1299 cells(P＜0.05).Furthermore,knockdown of GINS1 resulted in reduced glucose consumption,reduced lactate production,and reduced expression levels of glycolytic-related proteins in A549 cells(P＜0.05);overexpression of GINS1 enhanced glycolytic level in H1299 cells(P＜0.05).The expression levels of Notch1,Notch3,phosphorylated-PI3K(p-PI3K),phosphorylated-AKT(p-AKT)and phosphorylated-mTORC1(Ser2448)[p-mTORC1(Ser2448)]in A549 cells were significantly decreased by GINS1 knockdown(P＜0.05),while the expression levels of P13K,AKT,mTOR and p-mTORC2(Ser2481)were not significantly changed(P＞0.05).Overexpression of GINS1 increased the levels of Notch1,Notch3 and PI3K/AKT/mTORC1 pathway phosphorylated proteins in H1299 cells(P＜0.05).Jagged1 significantly reversed the inhibition of glycolysis,prolif-eration and metastasis induced by GINS1 knockdown in A549 cells(P＜0.05),and LY3039478 significantly inhibited the en-hancement of glycolysis,proliferation and metastasis induced by GINS1 overexpression in H1299 cells(P＜0.05).Conclusion The expression of GINS1 enhances the expression of Notch1 and Notch3 receptors,and then phosphorylates and activates the downstream PI3K/AKT/mTORC1 signaling pathway to enhance the glycolysis,proliferation and metastasis of LUAD cells.

BACKGROUND:Research on foot and ankle proprioception is crucial for the rehabilitation of chronic ankle instability and geriatric diseases as well as for the improvement of body posture control and motor performance.Previous studies have often studied the sensory evaluation of the foot and ankle joints separately,which has limitations for a comprehensive understanding of their sensory function. OBJECTIVE:The foot and ankle complex is the only part in direct contact with the support surface,and plays an important role in the collective sensory feedback and regulation and balance control.By combing the existing investigation and research of foot and ankle ontology,the measurement and evaluation methods of the sensation of the foot and ankle complex are combed,in order to pave the way and provide the theoretical basis for future related studies. METHODS:Chinese terms"(foot OR foot ankle OR ankle)AND(sensation OR proprioception)"and English terms"(foot OR ankle)AND(feel OR proprioception)"were used as the keywords for retrieving relevant literature in the Web of Science,PubMed,and CNKI.We understood the basic concepts,current status and scope of research on the foot and ankle,summarized and evaluated the proprioceptive evaluation methods of the foot and ankle,and finally included 57 papers for further review. RESULTS AND CONCLUSION:The evaluation of foot and ankle complex sensation was mainly divided into sensory evaluation of the foot and proprioceptive evaluation of the ankle joint.The sensory evaluation of the foot mainly describes the sensation of the skin and the sensory feedback under the intervention conditions.The methods mainly include the pressure sensory threshold test,the two-point discrimination test of the foot(planar and plantar),and the duration test of skin vibration sensation.Ankle joint proprioception evaluation focuses on the description of joint position,motion range,force value and functional performance.The methods are mainly divided into static joint angle reset test,motion minimum threshold test,force perception reproduction test and dynamic balance,speed and walking ability tests.The report of quantitative results is generally expressed by"an error,"which is generally divided into absolute error,relative error,constant error,etc.To conclude,the foot and ankle complex has specific sensory capabilities,including foot sensation and ankle proprioception,which affect the quality of life and athletic performance of humans.Weakness of both foot sensation and ankle proprioception is associated with reduced human balance,and the combined measurements of the two can comprehensively and effectively evaluate foot and ankle function.The combination of foot and ankle sensory measures is selected according to different research needs and various influencing factors such as environment,emotion and reporting style are fully considered,to improve the validity of measurement and evaluation.
