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 investigate the association between nighttime sleep duration, physical activity and disability among the elderly, so as to provide the basis for reduce the risk of disability and promote healthy aging. Methods: Based on the 2020 database of China Health and Retirement Longitudinal Study (CHARLS), demographic information, lifestyle behaviors, chronic diseases and nighttime sleep duration were collected from people aged 60 years and older. Physical activity level was evaluated using the International Physical Activity Questionnaire-Short. Disability status was measured using the basic Activities of Daily Living (ADL) scale. Association between nighttime sleep duration, physical activity and disability among the elderly were analyzed using multivariable logistic regression model. Results: Totally 11 126 elderly participants were enrolled, with 5 423 males (48.74%) and 5 703 females (51.26%). The mean age was (69.92±7.08) years. Among them, 6 838 individuals (61.46%) had a nighttime sleep duration of <7 hours, and 2 247 individuals (20.20%) had a physical activity level of <600 MET-min/week. A total of 3 213 individuals were identified as having disability, with a detection rate of 28.88%. Multivariable logistic regression analysis showed that, after adjusting for age, gender, marital status, education level, residence, smoking, alcohol consumption, and multimorbidity of chronic diseases, compared with a nighttime sleep duration of 7-8 hours, those with <7 hours (OR=1.535, 95%CI: 1.386-1.700) and >8 hours (OR=1.186, 95%CI: 1.003-1.402) had an increased risk of disability by 53.5% and 18.6%, respectively. Compared with a physical activity level of ≥600 MET-min/week, those with <600 MET-min/week (OR=2.106, 95%CI: 1.901-2.335) had an increased risk of disability by 110.6%. Compared with those who had a nighttime sleep duration of 7-8 hours and a physical activity level of ≥600 MET-min/week, the elderly with a nighttime sleep duration of <7 hours and a physical activity level of <600 MET-min/week (OR=3.299, 95%CI: 2.831-3.843), a nighttime sleep duration of >8 hours and a physical activity level of <600 MET-min/week (OR=2.566, 95%CI: 1.954-3.369), a nighttime sleep duration of 7-8 hours and a physical activity level of <600 MET-min/week (OR=1.911, 95%CI: 1.564-2.334), and a nighttime sleep duration of <7 hours and a physical activity level of ≥600 MET-min/week (OR=1.503, 95%CI: 1.334-1.692) had an increased risk of disability by 229.9%, 156.6%, 91.1%, and 50.3%, respectively. Conclusion Short or long nighttime sleep duration and low physical activity levels can increase the risk of disability in the elderly.

Lateral organ boundaries (LOB) domain (LBD) genes encode a family of transcription factors ubiquitous in higher plants, playing crucial roles in the growth, development, and stress responses. Hippophae rhamnoides, known for its drought, cold, and saline-alkali tolerance, offers significant economic benefits and ecological values. Utilizing the whole genome data and bioinformatics approaches, this study identified and analyzed the LBD gene family in H. rhamnoides. Additionally, we examined the expression pattern of HrLBD genes by integrating the transcriptome data from male and female flower buds in development. Eleven LBD genes were identified in H. rhamnoides, and these genes were distributed on five chromosomes. The HrLBD proteins showed the lengths ranging from 159 aa to 302 aa, the molecular weights between 18 249.91 Da and 33 202.01 Da, and the subcellular localization in the nucleus or chloroplasts. LBD protein domains and gene structures were highly conserved, featuring similar motifs. The phylogenetic analysis of HrLBD genes and the LBD genes in Arabidopsis thaliana and Hordeum vulgare revealed that HrLBD genes falled into two major categories: Class Ⅰ and Class Ⅱ. The transcriptome data and RT-qPCR showed that HrLBD genes were highly expressed in male flower buds, with up-regulated expression levels throughout bud development, indicating a role in the specific stage of male flower bud development. This study lays a theoretical foundation for exploring the roles of HrLBD genes in the growth, development, and sex differentiation of H. rhamnoides flower buds.

OBJECTIVE To optimize the rivaroxaban dosing regimen for anticoagulation in patients with different renal function levels. METHODS The administration regimen was determined based on the drug instructions for rivaroxaban and the actual medication situation of the patient. The target concentration range and the subsection interval were established using rivaroxaban blood minimum concentration for patients from Hebei General Hospital and reference range of rivaroxaban laboratory monitoring concentration recommended by International Council for Standardization in Hematology. The probability of different dosing regimens in each target concentration range was investigated with Monte Carlo simulation using Oracle Crystal Ball software （V11.1.2.4）. RESULTS A total of 97 patients with non-valvular atrial fibrillation were enrolled and the minimum concentration of rivaroxaban was tested 125 times with a median trough concentration of 32.2 ng/mL； a total of 121 patients with venous thrombosis were enrolled and the minimum concentration was tested 159 times with a median minimum concentration of 31.0 ng/mL. The reference range for steady-state minimum concentration in patients with non-valvular atrial fibrillation was 12-137 and 3-153 ng/mL， while the reference range for steady-state minimum concentration in patients with venous thrombosis was 6-239 and 3-224 ng/mL. Monte Carlo simulation results showed that in patients with non-valvular atrial fibrillation， the optimal rivaroxaban dosing regimen for patients with glomerular filtration rate （eGFR） 0-30 mL/min was 5 mg once daily； for patients with eGFR＞30-60 mL/min， the optimal dosing regimen was 10-20 mg once daily or 5 mg twice daily； for patients with eGFR＞60-90 mL/min， the optimal dosing regimen was 15-30 mg once daily or 5-10 mg twice daily； for patients with eGFR＞90-120 mL/min， the optimal dosing regimen was 25-30 mg once daily or 5-15 mg twice daily. For patients with venous thrombosis， it is not recommended to use rivaroxaban more than 5 mg once daily for patients with eGFR 0-30 mL/min； the optimal dosing regimens of rivaroxaban were 5 mg once daily for patients with eGFR＞30-60 mL/min， 25- 30 mg once daily or 5-15 mg twice daily for patients with eGFR＞60-90 mL/min， 10-15 mg twice daily for patients with eGFR＞ 90-120 mL/min. CONCLUSIONS Rivaroxaban should be selected carefully as the anticoagulants for patients with severe renal function impairment. Rivaroxaban possesses a wide reference range in the minimum concentration and considerable individual variability. The dosage and frequency of rivaroxaban can be personalized through the Monte Carlo simulation method， taking into account patients’ renal function.

Tafamidis is a selective stabilizer for transthyretin （TTR）， used for the treatment of transthyretin amyloidosis with cardiomyopathy （ATTR-CM） and transthyretin amyloidosis with polyneuropathy （ATTR-PN）. This article provides a review of the basic information and clinical studies on the efficacy and safety of tafamidis. It is found that tafamidis slows down or prevents the progression of TTR amyloidosis by inhibiting the dissociation of TTR tetramers. Multiple clinical studies have shown that tafamidis has good efficacy and safety， significantly reducing all-cause mortality and cardiovascular-related hospitalization rates in patients with amyloidosis， and delaying disease progression. Although tafamidis treatment may have certain limitations， it is still a key drug for the treatment of TTR amyloidosis， and the first drug approved for the treatment of ATTR-CM.
