OBJECTIVE To provide direction and reference for the adjustment of the discount rate （DR） in China’s pharmacoeconomic guidelines. METHODS Search was conducted on the official websites of the International Society for Pharmacoeconomics and Outcomes Research， health technology assessment agencies in various countries/regions， as well as relevant websites of other upper-middle-income or high-income countries/regions. The recommended DR， adjustment trends， and setting rationales in pharmacoeconomic evaluation guidelines across different countries/regions were then summarized and compared. Based on theoretical derivation and literature analysis， the effects of different DR on the incremental cost-effectiveness ratio （ICER） were examined. RESULTS & CONCLUSIONS Among the 40 included guidelines， the base-case DR ranged from 1.5% to 5%， with 5% being the most common value； the range for sensitivity analysis was 0 to 12%. Thirty-six countries/regions applied the same DR to both costs and health outcomes， while in the Netherlands， Belgium， Poland and Czech Republic， DR for costs was higher than for health outcomes. In recent years， Korea， France and Ireland had lowered their DR in response to economic changes， whereas the Netherlands and Czech Republic had raised their DR for cost. The setting of the DR was primarily based on the public project investment interest rate or referred to recommendations from internationally authoritative institutions and other relevant guidelines. The direction and magnitude of the impact of different DR on the ICER largely depended on the distribution of costs and health outcomes between the intervention and reference measure. The setting and adjustment of DR were closely associated with the economic environment. Based on international experience, the DR in China can be lowered by 0.5% to 1.5%， and localized empirical research can be conducted using internationally common estimation methods.

Objective To discuss the morphological characteristics of three types of clinically rare cerebral aneurysms and arterial bifurcations.Methods A total of 17 patients with clinically rare cerebral aneurysms,including anterior cerebral artery-pericallosal artery aneurysms(ACA-PA aneurysms,n=8),internal carotid artery-anterior choroidal artery bifurcation aneurysms(ICA-AChA aneurysms,n=5)and vertebral artery-posterior inferior cerebellar artery bifurcation aneurysms(VA-PICA aneurysms,n=4),who received treatment in the Shijiazhuang People's Hospital between January 2017 and April 2020 were enrolled in this study.The clinical baseline data were recorded,and the morphological parameters of the aneurysms were determined.The bifurcation angle,small lateral angle and large lateral angle were defined as φ1,φ2 and φ3,respectively.D1,S1 and T1 represented the diameter,cross-sectional area and tortuosity of the main blood vessel,respectively.D2,S2 and T2 were defined as the corresponding parameters of the branch vessel forming small lateral angle with the main vessel.D3,S3 and T3 were the corresponding morphological parameters of the contralateral branch vessel.Results All of the ICA-AChA and VA-PICA bifurcation aneurysms were type D aneurysms and oriented towards the small lateral angle.Six ACA-PA bifurcation aneurysms were type C aneurysm,and 5 of them were oriented toward the small lateral angle.The S2 and φ2 of the ACA-PA and ICA-AChA bifurcations harboring aneurysms were significantly smaller than S3 and φ3(P＜0.05),while T2 was remarkably largerthan T3(P＜0.05).The VA-PICA bifurcations also showed a similar manifestations.Conclusion These three types of clinically rare cerebral aneurysms are mostly oriented towards the small lateral angle,and the diameter and cross-section area of the branch forming small lateral angle with parent artery were smaller than those of the contralateral branch vessel,while the tortuosity was greater than that of the contralateral branch.

Objective: To explore the causal relationship between adolescent school connectedness and the co-occurrence with health risk behaviors among junior high school students, so as to provide the reference for reducing the occurrence of adolescents health risk behaviors among junior high school students. Methods: A total of 924 students from two junior high schools in Jishou City were selected by the convenience sampling and cluster sampling methods, and two follow up surveys were conducted at 6 month intervals in April (T1) and October (T2) of 2023 using the Adolescent Health Risk Behavior Questionnaire and the School Connection Scale. The scores of the co-occurrence of school connectedness and health risk behaviors among junior high school students were compared by different survey periods and genders using the t-test, and cross lagged analyses were performed using Mplus 8.3 software. Results: School connectedness scores among junior high school students in T1 and T2 surveys were (38.86±7.46) (37.87± 7.71 ) and co-occurrence of health risk behaviors scores were (1.64±0.68) (1.83±0.53), respectively, and the differences between the scores of the 2 surveys were statistically significant ( t=4.24, -4.14, P <0.05). The correlation between school connectedness and co-occurrence of health risk behaviors were statistically significant in both surveys ( r =-0.46 to -0.33, P <0.05). Cross lagged analyses showed that school connectedness in T1 negatively predicted the co-occurrence of health risk behaviors in T2 ( β =-0.08), and the co-occurrence of health risk behaviors in T1 negatively predicted the school connectedness in T2 ( β =-0.15) ( P <0.05). Conclusions There is a longitudinal causal relationship between school connectedness and co-occurrence of health risk behaviors among junior high school students. School connectedness should be improved through various ways to reduce the co-occurrence of health risk behaviors.

Objective: To provide the mechanism-based pharmacotherapy of the Huatan Qushi formula (HTQS formula), for the health management and treatment of non-alcoholic fatty liver disease (NAFLD). Methods: A rat model of NAFLD was employed to examine the efficacy and safety of the HTQS formula. In vivo active components and potential mechanisms of the HTQS formula were identified using UPLC‒MS/MS combined with network pharmacology. The influence of the HTQS formula on the dominating proteins in PI3K/Akt pathway was validated in vivo using western blot. Finally, 16S rRNA sequencing of the gut microbiome was conducted followed by targeted metabolomics detecting fecal short-chain fatty acids (SCFAs) and bile acids to determine the impact of the HTQS formula on gut microbiota. Results: The HTQS formula reduced weight gain and hepatic steatosis in NAFLD rats and decreased serum total cholesterol (TC), triglycerides, blood glucose, and insulin resistance (IR) without causing liver or kidney injury. We detected 28 components using UPLC‒MS/MS and identified 439 shared targets between NAFLD and the HTQS formula. Primarily, we focused on the PI3K/Akt signaling pathway based on protein‒protein interaction network analysis. We validated that the HTQS formula inhibited liver steatosis and inflammation by increasing the phosphorylation levels of PI3K, AKT, P27, GSK3β in the PI3K/Akt signaling pathway. 16S rRNA sequencing revealed that the HTQS formula reduced the abundance of the genus Family_XIII_AD3011_group, which was positively correlated with IR and taurodeoxycholic acid. In addition, Lachnospiraceae_UCG_010 inversely correlated with TC and five bile acids, which could be essential to the therapeutic effect of the HTQS formula against NAFLD. Conclusions The HTQS formula proved to be an effective pharmacotherapy for NAFLD without causing liver or kidney injury. Multiple potent components of the HTQS formula could alleviate liver steatosis and lipid metabolism disorder by modulating the PI3K/Akt signaling pathway and restoring gut microbiota composition.
