OBJECTIVE To evaluate the efficacy, safety and economics of calcium channel modulators in the treatment of diabetic peripheral neuropathic pain (DPNP), and provide evidence-based evidence for clinical drug selection and decision-making. METHODS PubMed, Embase, Cochrane Library, CNKI, Wanfang data, VIP net, CBM and official websites of foreign health technology assessment (HTA) institutions were systematically searched to collect HTA reports, systematic review/meta-analyses, and pharmacoeconomic studies of pregabalin, gabapentin, crisugabalin, and mirogabalin for the treatment of DPNP. The timeframe for all searches was from the inception to June 2024. After data extraction and quality assessment, the results of the included studies were analyzed descriptively. RESULTS A total of 16 articles were included, involving 1 HTA report, 7 systematic reviews/meta- analyses, and 8 pharmacoeconomic studies. No studies on crisugabalin were retrieved. Compared with placebo, both pregabalin and mirogabalin reduced end point pain scores and increased the proportion of patients with ≥30% and/or ≥50% reduction in pain scores. Pregabalin also improved patient global impression of change (PGIC). Gabapentin was similar to placebo in reducing end point pain scores and increasing the proportion of patients with ≥30% and/or ≥50% reduction in pain scores, but gabapentin improved PGIC of patients. Compared with pregabalin, mirogabalin was more effective in the treatment of pain. The safety of pregabalin and mirogabalin was similar, and compared with placebo, both pregabalin and mirogabalin increased the risk of common adverse reactions such as dizziness and somnolence. The safety of gabapentin was similar to placebo and duloxetine. Compared with duloxetine, pregabalin and gabapentin were not cost-effective. Compared with gabapentin, pregabalin was cost-effective. Mirogabalin was cost-effective, as compared with placebo and pregabalin. CONCLUSIONS Pregabalin and mirogabalin are effective in the treatment of DPNP, the efficacy of mirogabalin is better than pregabalin, and the safety is similar between them. The economic conclusions vary from country to country, pending a pharmacoeconomic study based on our population.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca2+ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca2+ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.

OBJECTIVE To evaluate the cost-effectiveness of toripalimab combined with paclitaxel (albumin binding type) in the treatment of metastatic or recurrent triple-negative breast cancer (TNBC). METHODS Based on the data of TORCHLIGHT clinical trial, a three-state partitioned survival model including progression-free survival, disease progression, and death was established. The simulation cycle was 21 days, the study duration was 10 years, and the discount rate was 5%. Using quality- adjusted life year (QALY) and cost as output indicators, a cost-effectiveness analysis method was adopted to calculate the incremental cost-effectiveness ratio (ICER) of toripalimab combined with paclitaxel (albumin binding type) versus placebo combined with paclitaxel (albumin binding type). Using three times the per capita gross domestic product (GDP) of China in 2023 as the willingness-to-pay(WTP) threshold(268 074 yuan/QALY), the cost-effectiveness of the above two regimens was evaluated, and the sensitivity analysis was conducted. RESULTS ICER of toripalimab combined with paclitaxel (albumin binding type) versus placebo combined with paclitaxel (albumin binding type) in the treatment of Chinese metastatic or recurrent TNBC patients was 176 347.17 yuan/QALY, which was lower than the WTP threshold set in this study, demonstrating the cost-effectiveness of this regimen. The results of the single-factor sensitivity analysis showed that the parameters such as the cost of toripalimab, discount rate, and utility value of the progression-free survival state had a great impact on the ICER. The results of the probabilistic sensitivity analysis indicated that the results of the basic analysis were robust. CONCLUSIONS When three times the per capita GDP of China in 2023 is used as the WTP threshold, compared with the regimen of placebo combined with paclitaxel (albumin binding type), toripalimab combined with paclitaxel (albumin binding type) is cost-effective in the treatment of metastatic or recurrent TNBC.

OBJECTIVE To evaluate the cost-utility of benmelstobart combined with anlotinib and chemotherapy as first-line treatment for extensive-stage small cell lung cancer (ES-SCLC) from the perspective of China’s healthcare system. METHODS Based on the data from the ETER 701 study, a partitioned survival model was constructed with a cycle of 3 weeks to simulate the total cost, quality-adjusted life years (QALY), and incremental cost-effectiveness ratio (ICER) over 10 years for patients with ES- SCLC treated with benmelstobart plus anlotinib and chemotherapy, or chemotherapy alone. One-way sensitivity analysis and probability sensitivity analysis were performed to verify the robustness of the simulation results. The willingness-to-pay (WTP) threshold was set at 3 times the per capita gross domestic product (GDP) of China in 2023, which amounted to 268 074 yuan/QALY. RESULTS Compared with chemotherapy alone, benmelstobart combined with anlotinib and chemotherapy gained 0.438 QALY more at the cost of 403 505.55 yuan more, with an ICER of 922 031.37 yuan/QALY, which was higher than the WTP threshold set in this study. One-way sensitivity analysis showed that benmelstobart’s cost and utility value of the progression-free survival state had a greater impact on the ICER value; probabilistic sensitivity analysis confirmed the robustness of the model; only when the price of benmelstobart was reduced by 75.4%, the combined regimen would be cost-effective. CONCLUSIONS The first-line treatment of ES-SCLC with benmelstobart combined with anlotinib and chemotherapy is not cost-effective from the perspective of China’s healthcare system at present.

OBJECTIVE To evaluate the cost-effectiveness of capecitabine metronomic chemotherapy combined with aromatase inhibitor (AI) versus AI monotherapy as first-line treatment for hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer, thereby providing evidence-based support for clinical therapeutic decision- making and healthcare policy formulation. METHODS Based on the MECCA trial, a partitioned survival model was constructed using a 4-week cycle length to simulate outcomes over patients’ lifetime. The model outputs included total costs, quality-adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed to validate the robustness of base-case results, while scenario analyses examined the cost-effectiveness of both treatment strategies under 10-year, 20-year, and lifetime time horizons. RESULTS With the willingness-to-pay (WTP) threshold set at 1 times China’s 2024 per capita gross domestic product (GDP) (95 749 yuan/QALY), patients receiving capecitabine metronomic chemotherapy combined with AI regimen gained incremental utility (0.66 QALYs) while incurring higher costs, with ICER of 27 684.85 yuan/QALY. Results of the one-way sensitivity analysis showed that factors with significant impacts on ICER included the cost discount rate, drug costs of the capecitabine metronomic chemotherapy combined with AI group, utility value in the progression-free survival state, follow-up costs, and treatment costs in the subsequent stablephase. Probabilistic sensitivity analysis indicated that when the WTP threshold ≥49 250 yuan/QALY, the capecitabine metronomic chemotherapy combined with AI regimen had a 100% probability of being cost-effective. Scenario analysis results demonstrated that capecitabine metronomic chemotherapy combined with AI regimen was more cost-effective than the AI alone regimen across 10-year, 20-year, and lifetime study horizons. CONCLUSIONS Under the premise that the WTP threshold is set at 1 times China’s per capita GDP in 2024, capecitabine metronomic chemotherapy combined with AI regimen is more cost-effective than the AI alone regimen as the first-line treatment for HR+/HER2- metastatic breast cancer.

OBJECTIVE To evaluate the cost-effectiveness of sacituzumab tirumotecan (ST) versus chemotherapy treatment physician’s choice (TPC) as second-line and later-line treatment for metastatic triple-negative breast cancer (mTNBC) from the perspective of China’s healthcare system. METHODS A partitioned survival model was constructed based on the OptiTROP-Breast 01 trial, with a cycle length of 4 weeks and a time horizon of 10 years, applying a 5% discount rate. Quality adjusted life year (QALY) and costs were used as outcome measures, and the incremental cost-effectiveness ratio (ICER) of ST versus TPC for second-line and later-line treatment of mTNBC was calculated. Sensitivity analyses were conducted to validate the robustness of the base-case results. RESULTS At a willingness-to-pay threshold (WTP) of 3 times China’s 2024 per capita gross domestic product (GDP) (287 247 yuan/QALY), patients receiving ST gained incremental utility (0.42 QALY) at a higher cost, yielding an ICER of 205 562.07 yuan/QALY, which was lower than WTP, indicating that ST was more cost-effective compared to TPC. One-way sensitivity analysis revealed that key factors influencing the ICER included the utility value of progression-free survival and the price of ST. Probabilistic sensitivity analysis and scenario analysis showed that the base-case results were robust. CONCLUSIONS From the perspective of China’s healthcare system, at a WTP of 3 times China’s per capita GDP, ST is more cost-effective than TPC as second-line and later-line treatment for mTNBC.

Objective:
To analyze the phylogenetic characteristics of VP1 gene of Coxsackievirus A10 (CVA10) isolates from 2004 to 2023, and to understand the genetic evolution and epidemic trends of CVA10, so as to provide references for the prevention and control of hand, foot, and mouth disease.
Methods:
The full-length sequences of the VP1 region of CVA10 isolates were retrieved from the BV-BRC database before December 15, 2024. Gene typing, sequence analysis, evolutionary analysis, and amino acid mutation site analysis were conducted using bioinformatics software.
Results:
A total of 1 253 CVA10 isolates VP1 region nucleotide full-length sequences from 2004 to 2023 were included, with 9 strains from 2004 to 2008, 338 strains from 2009 to 2012, and 906 strains from 2013 to 2023. China had the highest number of CVA10 isolates, with 1 143 strains accounting for 91.22%, and the predominant genotype was C3. Compared to the prototype strain, the nucleotide sequence homology of the VP1 region of CVA10 isolates ranged from 74.94% to 77.63%, while the amino acid sequence homology ranged from 88.59% to 93.62%. The third codon position preferred cytosine and thymine. The top three most abundant amino acids were threonine, alanine, and valine. The average relative synonymous codon usage of 30 amino acid codon groups was greater than 1. The average amino acid substitution entropy value was 0.04, with four amino acid mutation-prone sites identified, and the mutation-prone rate was 1.35%.
Conclusions
From 2004 to 2023, the majority of CVA10 isolates were primarily sourced from China, with genotype C3 being the predominant circulating strain in China. The nucleotide homology between the CVA10 isolates and the prototype strain was relatively low, and mutation-prone sites were identified, indicating that enhanced monitoring of viral variation is necessary.
