OBJECTIVE To comprehensively analyze the effectiveness， safety and economic value of carfilzomib in the treatment of multiple myeloma （MM）， and provide evidence-based guidance for clinical rational drug use. METHODS A systematic search was performed in PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang， VIP， and relevant health technology assessment （HTA） websites， from database inception to December 31， 2024. Two researchers independently screened studies based on predefined inclusion and exclusion criteria， extracted data， and assessed study quality. Descriptive statistical analyses were conducted. RESULTS A total of 21 studies were included， comprising 7 systematic reviews/meta-analyses， 5 clinical trials， 5 pharmacoeconomic studies， and 4 HTA reports. Effectiveness analysis indicated that， compared with control groups， carfilzomib significantly improved overall response rate and clinical benefit rate （ P ＜0.05）， prolonged progression-free survival， and enhanced patient’s quality of life （ P ＜0.05）， while its impact on overall survival remains to be further confirmed. Safety analysis showed there was no significant difference in the risk of peripheral neuropathy between carfilzomib and controls， while the risks of cardiotoxicity and hypertension were significantly increased （ P ＜0.05）. Economic analysis suggested that carfilzomib regimens demonstrated certain cost-effectiveness in second-line treatment in the U.S. and some European countries. However， its economic value was influenced by drug price， dosing regimen， and regional differences， and it may lack a cost advantage in some countries or in third-line treatment. CONCLUSIONS Carfilzomib shows definite efficacy and generally acceptable safety in the treatment of MM， but cardiotoxicity and hypertension risks require careful monitoring. Given its high treatment cost， pharmacoeconomic studies in the Chinese population are urgently needed.

Objective To investigate the molecular mechanism by which Lichong Xiaozheng Granules(LCXZ)sensitize ovarian cancer to cisplatin(DDP)treatment.Methods LC-MS analysis was used to identify the blood components of LCXZ after its administration in mice via gavage.In a BALB/c mouse model bearing subcutaneous ovarian cancer xenografts,the effects of daily gavage of distilled water(control group),intraperitoneal injection of DDP(5 mg/kg)once a week,or both DDP injection and daily LCXZK gavage(15 g/kg)on tumor growth were evaluated.Histopathological changes in the xenografts and kidneys were assessed with HE staining.RNA-seq was performed to identify the differentially expressed genes followed by KEGG pathway analysis.The changes in mitochondrial ultrastructure and expressions of mitochondrial apoptosis-related were examined with transmission electron microscopy and Western blotting.Results A total of 218 blood-borne components of LCXZ were detected by LC-MS.In the tumor-bearing mice,treatments with DDP and DDP combined with LCXZ redcued the tumor volume by 60.3%and 72.6%compared with that in the control group,respectively.Transcriptomic analysis revealed significantly upregulated ANT3 expression in both the two treatment groups.Molecular docking indicated that the main active components of LCXZ were capable of binding to adenine nucleotide translocator 3(ANT3)with binding energies below-6 kcal/mol.Transmission electron microscopy showed obvious mitochondrial swelling and outer-membrane damage in the tumor cells in DDP-treated mice,and these changes were more pronounced in the combined treatment group.The expression levels of BAX,ANT3,cleaved caspase-3 and cleaved caspase-9 were increased,whereas BCL-2 expression was decreased significantly in the tumor cells in both the DDP and DDP+LCXZ groups.Conclusion LCXZ enhances the therapeutic efficacy of cisplatin against ovarian cancer xenografts in mice by promoting mitochondrial dysfunction and activating apoptotic signaling pathways via upregulating ANT3.

Total knee arthroplasty(TKA)is mainly used for the treatment of advanced knee osteoarthritis.Accurate preoperative planning and rapid prosthesis recognition are essential for smooth operation and postoperative rehabilitation.However,manual prosthesis recognition rely on doctors'experience,easily leading to misdiagnosis or missed diagnosis.Recent years,artificial intelligence(AI)had been integrated with medical imaging,represented by machine learning(ML)and its branch deep learning(DL),and displayed relatively powerful auxiliary functions in TKA.The research status and application progresses of AI combined with imaging in TKA were reviewed in this article.

Objective:This study aims to explore the job preferences of county-level Centers for Disease Control and Prevention(CDC)personnel and to provide a basis for the development of effective incentive mechanisms.Methods:This study used a combination of stratified sampling and latent class sampling to investigate 1 809 respondents from 56 county-level CDCs in Shandong Province,Hubei Province,and Guizhou Province.Data were analysed using a mixed logit model and a latent class model,and willingness to pay was calculated.Results:The results of the mixed logit model showed that,all attributes and their levels had a significant influence(P<0.05),with establishment being the most important motivating factor(β=2.249).In the latent class model,respondents were divided into three categories.The main differences between the three classes were the choice of exit options and differences in preferences for job attributes.Conclusion:County-level CDC personnel preferred jobs with higher incomes,very good benefit levels,establishment,low workload,better recognition and respect from the public,more opportunities for career advancement,and abundant training opportunities.It is recommended that the total number of establishment should be rationally controlled and dynamically adjusted to balance the differences between working conditions within and outside the establishment;that a comprehensive approach should be adopted to improve both hygiene and motivation factors;and that different incentives should be adopted for different categories of CDC staff. Those who are willing to make a change should be provided with more opportunities for training and career advancement.

Objective:To investigate the role of YTHDF2 in cervical lesions and its potential molecular mechanism.Methods:Gene expression data of cervical tissue were obtained from the GEO database to analyze the expression of YTHDF2 mRNA and perform pathway enrichment analysis. Patients with cervical lesions diagnosed by thinprep cytologic test in Gynecological Outpatient Department of Maternal and Child Health Hospital in Jiexiu, Shanxi Province, were selected as the research subjects. Data of cervical lesions and cervical exfoliated cells were collected. HPV infection status was detected by flow-through hybridization, and the expression of YTHDF2 mRNA was detected by reverse transcription real-time polymerase chain reaction. The expression of YTHDF2 in cervical lesions and the mediating role of HPV infection in the relationship between YTHDF2 and squamous intraepithelial lesion (SIL) were evaluated. YTHDF2-related genes were screened from multiple datasets in the GEO and ENCORI databases, and their expression, immune infiltration, and survival analysis were performed to assess the association between YTHDF2 and prognosis. Results:Compared with normal cervical tissue, YTHDF2 was highly expressed in cervical lesion tissue ( P<0.05). A total of 3 672 differentially expressed genes were screened from the dataset GSE49339. Gene Ontology analysis showed that YTHDF2 was mainly involved in transcription regulation. Kyoto Encyclopedia of Genes and Genomes analysis showed that YTHDF2 might be related to HPV infection and other signaling pathways. In the mediation analysis, χ2 test results showed that the expression level of YTHDF2 was significantly different among groups ( χ2=22.47, P<0.001). Trend χ2 test further showed that the expression level of YTHDF2 was upregulated with the degree of cervical precancerous lesions (trend χ2=10.26, P=0.001). Multivariate logistic regression analysis indicated that high YTHDF2 expression increased the risk of low-grade squamous intraepithelial lesions ( OR=3.15, 95% CI: 1.93-5.15) and high-grade squamous intraepithelial lesions ( OR=1.85, 95% CI: 1.01-3.39). Mediation effect analysis revealed a partial mediating effect of HPV infection between YTHDF2 and SIL, accounting for 32.02% of the total effect. Twelve YTHDF2 related genes were screened by the intersection of multiple datasets. The immune infiltration analysis results showed that YTHDF2 and related genes KLF4, E2F3 and HOXC6 were associated with immune infiltration (all P<0.05). Multivariate Cox proportional hazard regression model analysis showed that low expression of KLF4 ( HR=0.53, 95% CI: 0.30-0.94) and high expression of RHOB ( HR=1.80, 95% CI: 1.04-3.13) were risk factors for the prognosis of cervical cancer. Conclusion:YTHDF2 is highly expressed in cervical lesions and may have been involved in the regulation of HPV infection-related pathways and its downstream related genes are related to immune infiltration and prognosis of cervical cancer, providing a theoretical basis for the study of mechanisms related to cervical lesions.
