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 investigate the relationship between serum peroxiredoxin 6(PRDX6)and annexin A1(ANXA1)levels and the severity and prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)compli-cated with type II respiratory failure.Methods A total of 257 patients with AECOPD complicated with type II respiratory failure(respiratory failure group),130 patients with stable COPD(stable COPD group)and 130 healthy subjects(control group)were selected from the Panzhihua University Affiliated Hospital from December 2021 to December 2023.According to the oxygenation index,AECOPD patients with type II respiratory failure were divided into mild respiratory failure group(n=101),moderate respi-ratory failure group(n=80)and severe respiratory failure group(n=76).According to the 28-day prognosis,they were divided into death group(n=62)and survival group(n=195).Serum PRDX6 and ANXA1 levels were detected by enzyme-linked immu-nosorbent assay(ELISA).The correlation between serum PRDX6,ANXA1 levels and oxygenation index in AECOPD patients with type II respiratory failure was analyzed by Spearman correlation coefficient.Multivariate Logistic regression model was used to analyze the influencing factors of poor prognosis in patients with AECOPD complicated with type II respiratory fail-ure,and receiver iperating characteristic(ROC)curve was drawn to evaluate the predictive value of serum PRDX6 and ANXA1.Results The serum PRDX6 level in the respiratory failure group(41.54±4.28 pg/ml)was lower than that in the stable COPD group(61.38±4.94 pg/ml)and the control group(80.65±8.93 pg/ml),and the ANXA1 level(3.35±0.69 μg/L)was higher than that in the stable COPD group(2.13±0.61 μg/L)and the control group(1.03±0.14 μg/L),the differences were statistically sig-nificant(t=-33.894～21.727,all P<0.001).The serum level of PRDX6 in severe respiratory failure group(34.54±5.05 pg/ml)was lower than that in moderate respiratory failure group(43.90±4.72 pg/ml)and mild respiratory failure group(54.28±6.34 pg/ml),the serum level of ANXA1 in severe respiratory failure group(3.94±0.43 μg/L)was higher than that in moderate respi-ratory failure group(3.57±0.46 μg/L)and mild respiratory failure group(2.70±0.43 μg/L),the differences were statistically sig-nificant(t=-19.018～22.338,all P<0.001).Oxygen index was positively correlated with serum PRDX6(r=0.815,P<0.001)and negatively correlated with ANXA1(r=-0.781,P<0.001)in AECOPD patients with type II respiratory failure.The mortality rate of 257 AECOPD patients with type II respiratory failure was 24.12%(62/257)after 28 days of follow-up.Increase forced expi-ratory volume in the first second(FEV1)as a percentage of the predicted value,increased oxygenation index and increased PRDX6 were independent protective factors for the poor prognosis of AECOPD patients with type II respiratory failure(Wald χ2=-0.154,-0.014,-0.173,all P<0.05),increased ANXA1 was an independent risk factor(Wald χ2=0.250,P<0.05).The area un-der the curve of serum PRDX6 and ANXA1 combined to predict the poor prognosis of AECOPD patients with type II respiratory failure was 0.906,which was greater than 0.788 and 0.781 predicted by the two indicators alone,and the differences were statisti-cally significant(Z=4.243,4.224,all P<0.001).Conclusion The decrease of serum PRDX6 level and the increase of ANXA1 level are related to the aggravation and poor prognosis of AECOPD patients with type II respiratory failure.The value of serum PRDX6 combined with ANXA1 in predicting the prognosis of AECOPD patients with type II respiratory failure is high.

Objective:To investigate the impact of Tai Chi on brain network topology in patients with type 2 diabetes mellitus(T2DM)and mild cognitive impairment(MCI).Method:Patients with T2DM and MCI were recruited and randomly assigned to three groups:Tai Chi group(n=33),fitness walking group(n=31),and health education control group(n=35).Cognitive function was as-sessed using the Montreal Cognitive Assessment(MoCA)at baseline and after 24 weeks of intervention.Mag-netic resonance imaging(MRI)and graph theory methods were used to analyze characteristic path length,be-tweenness centrality,and nodal efficiency to evaluate brain network topology.Result:After 24 weeks,the MoCA score of the Tai Chi group significantly improved compared to the con-trol group(P=0.016),but there was no significant difference compared to the fitness walking group.No signif-icant changes in characteristic path length were observed among the three groups.Compared to the control group,the betweenness centrality in the Tai Chi group significantly increased in the right precentral gyrus,right middle temporal gyrus(temporoccipital part),and left angular gyrus.Additionally,the betweenness cen-trality in the bilateral middle temporal gyri(temporoccipital part)was higher in the Tai Chi group than in the fitness walking group.Nodal efficiency in the right supramarginal gyrus(posterior part)significantly increased in the Tai Chi group compared to the control group.Correlation analysis showed that the change in between-ness centrality of the left middle temporal gyrus in the Tai Chi group was positively correlated with the change in MoCA score(r=0.642,P＜0.001),and the nodal efficiency of the right supramarginal gyrus was also positively correlated with the change in MoCA score(r=0.372,P=0.033).Conclusion:This study preliminarily reveals that Tai Chi may improve cognitive function in patients with T2DM and MCI by modulating the local topological properties of brain networks,particularly in the left mid-dle temporal gyrus and right supramarginal gyrus.

OBJECTIVE To provide a reference for the early diagnosis， drug treatment and medication monitoring for patients with Lemierre’s syndrome. METHODS The doctors confirmed the diagnosis of the patient as having Lemierre’s syndrome based on the patient’s condition and the results of metagenomic next-generation sequencing （mNGS）， and the clinical pharmacists participated in the treatment process of the patient. During the treatment process， the clinical pharmacists suggested using piperacillin sodium and tazobactam sodium combined with metronidazole for anti-infective treatment against Fusobacterium necrophorum infection； clinical pharmacists recommend anticoagulant treatment with Enoxaparin sodium injection for left internal jugular vein thrombophlebitis. RESULTS The doctors accepted the suggestion of the clinical pharmacists， and the patient’s condition improved after treatment and was allowed to be discharged with medication. CONCLUSIONS By interpreting the results of mNGS， combined with the patient’s condition， the clinical pharmacists assist doctors in formulating individualized anti-infective and anticoagulant plans for the patient and provide medication monitoring， ensuring the safety and effectiveness of the patient’s medication.

Oral diseases concern almost every individual and are a serious health risk to the popula-tion.The restorative treatment of tooth and jaw defects is an important means to achieve oral function and support the appearance of the contour.Based on the principle of"learning from the nature",Deng Xu-liang's group of Peking University School and Hospital of Stomatology has proposed a new concept of"microstructural biomimetic design and tissue adaptation of tooth/jaw materials"to address the worldwide problems of difficulty in treating dentine hypersensitivity,poor prognosis of restoration of tooth defects,and vertical bone augmentation of alveolar bone after tooth loss.The group has broken through the bottle-neck of multi-stage biomimetic technology from the design of microscopic features to the enhancement of macroscopic effects,and invented key technologies such as crystalline/amorphous multi-level assembly,ion-transportation blocking,and multi-physical properties of the micro-environment reconstruction,etc.The group also pioneered the cationic-hydrogel desensitizer,digital stump and core integrated restora-tions,and developed new crown and bridge restorative materials,gradient functionalisation guided tissue regeneration membrane,and electrically responsive alveolar bone augmentation restorative membranes,etc.These products have established new clinical strategies for tooth/jaw defect repair and achieved inno-vative results.In conclusion,the research results of our group have strongly supported the theoretical im-provement of stomatology,developed the technical system of oral hard tissue restoration,innovated the clinical treatment strategy,and led the progress of the stomatology industry.
