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 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.

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.

Background China is a major coal producer and consumer country in the world. Coal workers' pneumoconiosis (CWP) is a primary factor endangering the occupational health of coal miners. Research on the disease burden of CWP and its changing trend is significant for disease prevention & control and associated policies. Objective To analyze the disease burden of CWP in China from 1990 to 2021 and its changing trend, and predict the disease burden from 2022 to 2035. Methods Using the Global Burden of Disease Study (GBD) database of 2021, numbers ofincident cases, prevalent cases, deaths, and disability-adjusted life years (DALYs) as well as crude and age-standardized rates of CWP in China were retrieved. Linear regression model was used to calculate the estimated annual percentage change (EAPC) of the age-standardized rates. Joinpoint regression model was used to analyze the temporal trend of disease burden and the disease burden of different sexes and age groups, and Bayesian age-period-cohort (BAPC) model was used to forecast the trend of CWP disease burden. Results In 1990, the incident, prevalent, and deaths cases of CWP in China were

Objective:To explore the causes and therapeutic effects of pelvic pain caused by rectal fistula or bladder fistula after comprehensive treatment of cervical cancer and rectal cancer (radiotherapy, surgery, chemotherapy, and other treatments).Methods:A retrospective analysis was conducted on the clinical and pathological data of patients with pelvic tumors admitted to the First People's Hospital of Yinchuan City, Ningxia and the Affiliated Cancer Hospital of Zhengzhou University from June 2016 to June 2022. The causes of persistent pelvic pain in patients after comprehensive treatment was investigated, and the corresponding therapeutic effects after clinical treatment was observed.Results:Thirty-two tumor patients experienced persistent pain after comprehensive treatment, including 22 cases of cervical cancer and 10 cases of rectal cancer. The preoperative pain of the entire group of patients was evaluated using the digital grading method, with a pain score of (7.88±1.31) points. Among the 32 patients, there were 16 cases of rectovaginal fistula or ileovaginal fistula, 9 cases of vesicovaginal fistula, 5 cases of rectoperineal fistula, and 2 cases of vesicovaginorectal fistula. Thirty-two patients were initially treated with medication to relieve pain, and according to the ruptured organs, a fistula was made to the corresponding proximal intestinal canal and renal pelvis to intercept the intestinal contents and urine. However, the pain did not significantly be improved. The pain score of treatment with the above methods for one week was (8.13±1.13) points, and there was no statistically significant difference compared to preoperative treatment ( P=0.417). In the later stage, based on a comprehensive evaluation of whether the tumor had recurred, the value of organ preservation, the benefits of surgery, the balance between survival time and improving quality of life, pathological organ resection or repair was performed. The surgical methods included repair of leaks, local debridement combined with irrigation of proximal intestinal fluid, distal closure of the sigmoid colon combined with proximal ostomy, posterior pelvic organ resection, anterior pelvic organ resection, and total pelvic organ resection. One week after surgery, the patients' pain completely relieved or disappeared, with the pain score of (1.72±1.37) points, which was significantly divergent from the preoperative and initial surgical treatments ( P<0.001). Conclusions:Palliative pyelostomy and proximal enterostomy cannot effectively alleviate persistent pelvic floor pain. The fundamental way to alleviate pain is complete blocking of the inflammatory erosion of the intestinal fluid and urine.

OBJECTIVE:
Anemoside B4 (AB4), the most abundant triterpenoidal saponin isolated from Pulsatilla chinensis, inhibited influenza virus FM1 or Klebsiella pneumoniae-induced pneumonia. However, the anti-SARS-CoV-2 effect of AB4 has not been unraveled. Therefore, this study aimed to determine the antiviral activity and potential mechanism of AB4 in inhibiting human coronavirus SARS-CoV-2 in vivo and in vitro.
METHODS:
The cytotoxicity of AB4 was evaluated using the Cell Counting Kit-8 (CCK8) assay. SARS-CoV-2 infected HEK293T, HPAEpiC, and Vero E6 cells were used for in vitro assays. The antiviral effect of AB4 in vivo was evaluated by SARS-CoV-2-infected hACE2-IRES-luc transgenic mouse model. Furthermore, label-free quantitative proteomics and bioinformatic analysis were performed to explore the potential antiviral mechanism of action of AB4. Type I IFN signaling-associated proteins were assessed using Western blotting or immumohistochemical staining.
RESULTS:
The data showed that AB4 reduced the propagation of SARS-CoV-2 along with the decreased Nucleocapsid protein (N), Spike protein (S), and 3C-like protease (3CLpro) in HEK293T cells. In vivo antiviral activity data revealed that AB4 inhibited viral replication and relieved pneumonia in a SARS-CoV-2 infected mouse model. We further disclosed that the antiviral activity of AB4 was associated with the enhanced interferon (IFN)-β response via the activation of retinoic acid-inducible gene I (RIG-1) like receptor (RLP) pathways. Additionally, label-free quantitative proteomic analyses discovered that 17 proteins were significantly altered by AB4 in the SARS-CoV-2 coronavirus infections cells. These proteins mainly clustered in RNA metabolism.
CONCLUSION
Our results indicated that AB4 inhibited SARS-CoV-2 replication through the RLR pathways and moderated the RNA metabolism, suggesting that it would be a potential lead compound for the development of anti-SARS-CoV-2 drugs.
