Objective To analyze the diagnosis cases of occupational benzene poisoning in gas station industry, and to explore the application of GC-MS technology in occupational disease diagnosis.   Methods The epidemiological method was used to describe and analyze the occupational disease diagnosis of 15 gas station workers , and qualitative screening of occupational hazard factors was performed by GC-MS.   Results All the 15 workers had more than one year's occupation history of oil refueling and unloading.  The clinical manifestations were consistent with the characteristics of chronic benzene poisoning in diagnosis of occupational benzene poisoning.  However, due to lack of evidence of occupational exposure to benzene and incomplete diagnostic data, occupational chronic benzene poisoning was not diagnosed. GC-MS technology was used to screen the occupational hazard factors in the gas station workplace, and benzene, n-pentane, n-hexane and so on were found.  Conclusion GC-MS is recommended for qualitative screening of organic solvents such as benzene when diagnosing occupational diseases for gas station workers , so as to accurately identify occupational hazard factors in workplaces and provide reliable basis for diagnosis of occupational diseases.

OBJECTIVE To evaluate the cost-effectiveness of finerenone combined with standard treatment regimen in the treatment of diabetic nephropathy （DN）. METHODS From the perspective of healthcare service providers， a Markov model was established to simulate the dynamic changes of each stage in DN patients who received finerenone combined with the standard treatment regimen or the standard treatment regimen alone based on the phase Ⅲ clinical trial study of finerenone for DN. Markov model was used to perform the cost-effectiveness of long-term effects and the costs of the two therapies with a simulation cycle of 4 months， a simulation period of 15 years and an annual discount rate of 5%. At the same time， one-way sensitivity analysis and probability sensitivity analysis were performed， and the stability of the results was validated. RESULTS Accumulative cost of the standard treatment regimen was 579 329.54 yuan， and the accumulative utility was 8.052 4 quality-adjusted life year （QALYs）； the accumulative cost of finerenone combined with the standard treatment regimen was 332 520.61 yuan， and the accumulative utility was 8.187 4 QALYs. Finerenone combined with the standard treatment regimen was more cost-effective. The results of one-way sensitivity analysis showed that dialysis status utility value， DN stage 3 utility value and DN stage 4 utility value had a great influence on the incremental cost-effectiveness ratio， but did not affect the robustness of the model. The results of probability sensitivity analysis showed that finerenone combined with the standard treatment regimen was more cost-effective with 100% probability. CONCLUSIONS For DN patients， finerenone combined with the standard treatment regimen is more cost-effective as an absolute advantage option.

OBJECTIVE To evaluate the cost-effectiveness of finerenone combined with standard of care （SoC） in the treatment of heart failure with mildly reduced ejection fraction （HFmrEF） or preserved ejection fraction （HFpEF）. METHODS Based on a phase Ⅲ clinical trial， a Markov model was constructed from the perspective of China’s healthcare system to compare the treatment outcomes of finerenone combined with SoC regimen versus SoC regimen alone in the treatment of different cardiac functional statuses of HFmrEF/HFpEF. Using quality-adjusted life year （QALY） as the health output index， 3 times China’s per capita GDP in 2023 as the willingness-to-pay （WTP） threshold， a simulation was conducted with a 3-month cycle length and a 10- year time horizon， incorporating an annual discount rate of 5%. The dynamic changes across various stages of HFmrEF/HFpEF treated with finerenone combined with SoC versus SoC alone were simulated to evaluate the long-term effectiveness and costs of the two treatment strategies. Additionally， one-way sensitivity analysis and probabilistic sensitivity analysis were performed， to test the robustness of the results. RESULTS The incremental cost-effectiveness ratio （ICER） of the finerenone combined with SoC regimen versus SoC regimen alone was 179 504.75 yuan/QALY， which was below the WTP threshold set in this study， indicating that the finerenone combined with SoC regimen possessed certain economic advantages. The results of one-way sensitivity analysis showed that the utility value of NYHA Ⅱ status， the drug price of finerenone， the discount rate， and the probability of hospital transfer for both groups had a great influence on ICER， but did not affect the robustness of the model. The probabilistic sensitivity analysis also confirmed the robustness of the model. CONCLUSIONS Under the WTP threshold set in this study， finerenone combined with SoC is cost-effective in the treatment of HFmrEF/HFpEF， compared with the SoC regimen.

OBJECTIVE To provide references for the clinical safe use of axitinib. METHODS Adverse drug event （ADE） data for axitinib were collected from the US FDA Adverse Event Reporting System （FAERS） database from the first quarter of 2012 to the fourth quarter of 2022. The data were mined and analyzed by utilizing the ratio-of-reporting-ratio （ROR） method and comprehensive standard method of the United Kingdom’s Medicines and Healthcare Products Regulatory Agency （MHRA） of proportional imbalance measurement. RESULTS A total of 13 962 reports of axitinib-related ADEs were obtained， with patients’ age concentrated in 65-85 years （43.25%）， gender predominantly male （65.23%）， country of reporting predominantly US （60.01%）， and serious ADE outcomes mostly hospitalization or prolonged hospitalization （31.51%）. A total of 172 ADE risk signals were detected， involving 18 system and organ classifications （SOC）， mainly systemic diseases and various reactions at the site of administration （3 749 cases， 30.84%） and gastrointestinal system diseases （2 067 cases， 17.00%）. ADE risk signals that occurred more frequently were generally consistent with the drug instruction， such as diarrhea， fatigue， and hypertension； new ADE risk signals requiring clinical attention were death， immune-mediated nephritis， and PT signals contained in the SOC of various benign， malignant， and tumors of undetermined nature （including cysts and polyps）. CONCLUSIONS For ADEs that occur frequently with axitinib and are already contained in the drug instruction （e.g. hypertension， diarrhea）， they should be adequately evaluated before administration， especially for patients with combined use of immune checkpoint inhibitors and patients with underlying hypertension； for ADEs with stronger signals and newer ADEs （e. g. death， disease progression， tumor progression）， the patient’s disease progression should be closely monitored during the treatment period for potentially fatal ADEs； for its rare ADEs （e. g.immune-mediated nephritis， scrotal ulcer， non-infectious encephalitis）， clinical validation should be further strengthened.
