OBJECTIVE To evaluate the cost-effectiveness of lecanemab for early Alzheimer disease （AD） from a whole-society perspective. METHODS Based on data from the Clarity AD study， a global multicenter， randomized， double-blind， placebo-controlled study of lecanemab for early AD， a Markov model was developed according to the disease progression of AD， with a monthly cycle and a time horizon extending to 99% patient mortality. Quality-adjusted life year （QALY） and incremental cost-effectiveness ratio （ICER） were used as outcome indicators， with a willingness-to-pay （WTP） threshold set at twice China’s per capita gross domestic product （GDP） for 2025 （199 330.00 yuan/QALY）. The model simulated the cost-effectiveness of lecanemab plus standard of care （SoC） versus placebo plus SoC for early AD. One-way sensitivity analysis， probabilistic sensitivity analysis， and scenario analysis were employed to test the robustness of the results. RESULTS Compared with placebo plus SoC， the ICER for lecanemab plus SoC was 4 364 711.54 yuan/QALY. One-way sensitivity analysis showed that the hazard ratio for disease progression， the price of lecanemab， body weight， the monthly progression probability of mild cognitive impairment， and the discount rate were key parameters affecting model robustness. Results of the probabilistic sensitivity analysis showed that the probability of lecanemab being cost-effective was 0 at the current WTP threshold. Scenario analysis indicated that a price reduction of at least 94.88% would be required for lecanemab to fall below the WTP threshold. CONCLUSIONS At the current WTP threshold， lecanemab plus SoC is not cost-effective compared with placebo plus SoC for early AD.

Objective:To explore ultrasound technique in relationship between three common abnormal placentas in singleton pregnancy,which included battledore placenta,velamentous placenta and circumvallate placenta,and clinically adverse pregnancy outcome.Methods:A retrospective study was conducted on the case documents of 330 singleton patients with abnormal placenta admitted and confirmed at Beijing Friendship Hospital from January 2020 to December 2024.Based on the morphology of abnormal placenta and the location of the umbilical cord attached to the placenta,they were divided into battledore placenta group(126 cases),velamentous placenta group(139 cases),and circumvallate placenta group(65 cases).Additionally,197 pregnant women with normal placenta who gave birth during the same period were selected as the normal placenta group.The perinatal outcomes of abnormal placenta and normal placenta were compared.Results:The coincidence rates of ultrasound diagnosis for the three abnormal placentas,which included battledore placenta,velamentous placenta and circumvallate placenta,were respectively 40.5%(51/126),46.0%(64/139)and 58.5%(38/65).The proportions of adverse pregnancy outcomes caused by three abnormal placentas were respectively 49.2%,69.8%and 47.7%,and the differences were statistically significant(x2=12.857,53.575,7.258,P<0.005).The quantity of adverse pregnancy outcome caused by velamentous placenta was the largest,which included increase of cesarean section rate,premature birth,fetal growth restriction,placental adhesions,postpartum hemorrhage,and neonatal asphyxia.Conclusion:All three kinds of abnormal placenta can increase the risk of adverse perinatal outcomes.It is important to pay attention to the situation of placenta in ultrasound during pregnancy,so as to make early diagnosis,and guide clinical work to adopt effective measures,which can reduce the occurrence of adverse pregnancy outcomes.

Objective To construct an animal model of dilated cardiomyopathy(DCM)with heart failure toxin syndrome that conforms to the characteristics of traditional Chinese medicine(TCM)syndrome and identify potential biomarkers or intervention targets for DCM with heart failure toxin syndrome.Methods Fifteen male SD rats were divided into a blank control,doxorubicin,or DCM with heart failure toxin syndrome group using a random number table method,with five rats per group.The doxorubicin group received intraperitoneal injection of doxorubicin at a dose of 1.25 mg/kg,administered on the first and fourth days of each week,along with a standard diet.The DCM with heart failure toxin syndrome group,in addition to the doxorubicin treatment,was given 42％white liquor(10 mL/kg)via gavage every other day,along with a 45％high-fat feed and 10％fructose water.The blank control group received intraperitoneal injection of an equivalent volume of phosphate-buffered saline at the same time points as the doxorubicin group,along with a standard diet.The model was established for 10 weeks.At the fourth and tenth weeks of modeling,echocardiography was performed to measure left ventricular ejection fraction(LVEF),fractional shortening(FS),systolic left ventricular posterior wall thickness(LVPWs),diastolic left ventricular posterior wall thickness,systolic left ventricular internal diameter(LVIDs),and diastolic left ventricular internal diameter(LVIDd);macroscopic changes in fur color of the rats were assessed using the red-green-blue colorimetric method.After modeling,the open field test was conducted to evaluate the exercise tolerance of the rats,and the grip strength test was performed to assess changes in forelimb grip strength.Hematoxylin-eosin,Masson,and wheat germ agglutinin staining were used to evaluate pathological changes in cardiac tissue.Bulk RNA sequencing analysis was performed to identify differentially expressed genes(DEGs)in the hearts of rats between the blank control and the DCM with heart failure toxin syndrome groups.Using DCM,the Blue value of rat fur color,and forelimb grip strength as phenotypic traits,weighted gene co-expression network analysis(WGCNA)was performed to screen for characteristic module gene sets(MEs)associated with DCM with heart failure toxin syndrome.Overlapping analysis was performed on DEGs,immune-related gene sets,and MEs,and the intersecting genes were identified as potential biomarkers or intervention targets for DCM with heart failure toxin syndrome.The sensitivity and specificity of these targets were evaluated using receiver operating characteristic(ROC)curve analysis.Results Compared with the blank control group,at the tenth week of modeling,the LVEF,FS,and LVPWs of rats in the doxorubicin group and the DCM with heart failure toxin syndrome group decreased,whereas LVIDs and LVIDd increased,and the movement distance of the open field test and forelimb grip strength were reduced(P＜0.05).At the 10th week of modeling,the Blue value of fur color in the DCM with heart failure toxin syndrome group was significantly lower than that of the blank control and doxorubicin groups(P＜0.05).Compared with the blank control group,rats in the doxorubicin and DCM with heart failure toxin syndrome groups exhibited significant cardiac dilation and increased immune cell infiltration in cardiac tissue,accompanied by collagen deposition and cardiomyocyte hypertrophy.Bulk RNA sequencing identified 2,003 DEGs,including 1,082 downregulated genes and 921 upregulated genes.WGCNA results revealed that the MEturquoise module had the strongest positive correlation with DCM and the strongest negative correlation with the Blue value and forelimb grip strength.The overlapping analysis identified four intersecting genes:bone morphogenetic protein 6(Bmp6),serine-threonine-protein kinase 1(Pak1),proto-oncogene JunD(JunD),and S100 calcium-binding protein A3(S100A3).ROC curve analysis demonstrated that these four genes exhibited high sensitivity and specificity for DCM with heart failure toxin syndrome.Conclusion The rat model constructed by intraperitoneal injection of doxorubicin combined with a high-fat feed,fructose water,and white liquor gavage closely aligns with the characteristics of the DCM with heart failure toxin syndrome.Bmp6,JunD,Pak1,and S100A3 are potential biomarkers or therapeutic targets for DCM heart failure toxin syndrome.

Objective To analyze temporal trends in infectious disease burden among Chinese elderly(≥60 years)using data from the Global Burden of Disease Study(GBD 2021),evaluate age-period-cohort effects on disease burden,predict trends through 2045,and propose evidence-based medication management strategies.Methods We conducted a threefold analysis of infectious disease burden from 1990 to 2021 using Joinpoint regression to identify temporal trends,Age-Period-Cohort(APC)modeling to disentangle epidemiological effects,and Nordpred projections for 2045 disease burden estimates.Results Over 32 years,all infectious disease categories except HIV/AIDS and sexually transmitted infections demonstrated significant declines.Enteric infections showed the most rapid reductions in mortality(AAPC=-7.85,P﹤0.001)and disability-adjusted life year rates(DALYR;AAPC=-7.18,P﹤0.001).We also found a significant decrease in the incidence of tropical diseases and malaria(AAPC=-6.77,P﹤0.001).APC analysis found that the age effect was mostly negative in terms of the annual percentage change in mortality and DALYR for each disease,except for HIV/AIDS,with an overall decline in period risk over time,and a generally higher risk of morbidity and mortality for the early birth cohort,and an overall decline in the risk of each disease as the year of birth progressed,but the risk of HIV/AIDS death and DALY period and cohort risks trended upward.While the overall risk for certain diseases was slightly higher in males compared to females,the trends were largely consistent across both sexes.In terms of projections,the absolute prevalence of respiratory infections and tuberculosis in terms of number of cases and age-standardized rates,and the growth of the disease burden of HIV/AIDS were particularly prominent,making them important health challenges for the future.The burden of disease in the elderly often results in issues such as potential polypharmacy,which must be addressed to improve medication management.Conclusions China has achieved remarkable progress in reducing infectious disease burdens among older adults,though HIV/AIDS and sexually transmitted infections present an escalating public health threat.These findings advocate for enhanced surveillance systems,age-specific prevention strategies,and precision medication protocols to optimize therapeutic outcomes in geriatric populations.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.
