OBJECTIVE To evaluate the cost-utiliby of capivasertib combined with fulvestrant for the second-line treatment of hormone receptor-positive/human epidermal growth factor receptor-2-negative （HR+/HER2－） advanced breast cancer from the perspective of the Chinese healthcare system. METHODS A partitioned survival model was constructed using clinical data from the CAPItello-291 trial. Costs and quality-adjusted life years （QALYs） were used as the output indicators of the model， and the incremental cost-effectiveness ratio （ICER） was used as the evaluation indicator of the model. Using three times the per capita gross domestic product （GDP） of China in 2024 as the willingness-to-pay threshold （WTP）， this study analyzed the cost-utility of capivasertib combined with fulvestrant versus fulvestrant monotherapy in the treatment of HR+/HER2－ advanced breast cancer， and conducted sensitivity analysis and scenario analysis under conditions where the price of capivasertib was reduced by 50%， 60%， 70% and 95%， respectively. RESULTS The results of the basic analysis showed that compared with the fulvestrant monotherapy regimen， the ICER of capivasertib combined with fulvestrant was 843 038.46 yuan/QALY， which was higher than the WTP（287 247 yuan/QALY）. The one-way sensitivity analysis revealed that the top three factors with the most substantial influence on ICER were the utility value in the progression disease state， the price of capivasertib， and the utility value inthe progression free survival state. Probabilistic sensitivity analysis demonstrated the robustness of the basic analysis results. Scenario analysis revealed that even if the price of capivasertib were reduced by 95%， capivasertib combined with fulvestrant did not exhibit cost-effectiveness at the current WTP. CONCLUSION At a WTP of three times China’s GDP per capita in 2024， compared to fulvestrant monotherapy， capivasertib combined with fulvestrant as the second-line treatment for HR+/ HER2－ advanced breast cancer is not cost-effective.

Parkinson's disease(PD)is the second most prevalent neurodegenerative disease and a major cause of movement disorders.Neuroinflammation plays an important role in the pathogenesis of PD.Icilin is a small molecule compound that has been reported to inhibit inflammation.Howev-er,its role in PD has not been reported.This study explored the effects of icilin on motor behavior,nerve damage,microglia activation,and neuroinflammation in MPTP-induced PD Meriones unguic-ulatus by behavioral experiments,immunohistochemistry,Western blot,and fluorescence quantifi-cation.The results showed that Icilin not only ameliorated motor dysfunction and neurological damage in MPTP-induced Meriones unguiculatus,but also inhibited microglia hyperactivation and its mediated neuroinflammation.The present study provides an evidence that icilin attenuates MPTP-induced neurodegenerative lesions in long-pawed gerbils,suggesting that it is a promising candidate for PD.

AIM:Hepatotoxicity of Brucea javani-ca picryl with broad-spectrum anticancer effect in nude mice based on hepatic drug metabolizing en-zyme CYP450 activity.METHODS:Fifty-six nude mice were randomly divided into blank group,Bru-cea javanica low-dose group(2 mg/kg),Brucea ja-vanica high-dose group(4 mg/kg),and cisplatin group(2 mg/kg),with 14 mice in each group.The blank group was injected with the same amount of normal saline every 3 days for 6 weeks.Calculate the mortality rate of nude mice in each group,ob-serve the general growth state of nude mice,re-cord the weight change of nude mice before and af-ter administration,weigh and record the liver weight after taking materials,and calculate the liv-er coefficient(liver weight/weight mass×100％),ob-serve and record the liver color and morphology.Hematoxylin-eosin(HE)staining was used to ob-serve the pathological changes of liver tissue.De-tection of alanine aminotransferase(ALT),aspar-tate aminotransferase(AST),lactate dehydrogenase(LDH),alkaline phosphatase(AKP)and albumin(ALB)levels in serum of nude mice by ELISA.Real-time PCR and Western blot were used to detect the mRNA and protein expression levels of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6 and CYP2C9,which were key enzymes of drug metabolism in nude mice liver.RESULTS:Compared with the blank group,the mortality rate of nude mice in the low-dose Brucea javanica bitter alcohol group was 0,the growth state was good,the diet,movement,and mental state were normal,the weight change and liver coefficient ratio were consistent,the liver color was ruddy,the liver lobule morphology was complete under the microscope,the structure was clear,the liver cells were arranged regularly,and there was no inflammatory cell infiltration.There was no significant difference in the content of ALT,AST,LDH,AKP,and ALB.There was no significant difference in the mRNA and protein expression of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6,and CYP2C9(all P＞0.05).Compared with the blank group,the mortality rate of nude mice in the high-dose group of Brucea javanica bitter alcohol was 14.3％,the growth state was slightly poor,the diet,movement,and mental state were reduced,the weight growth was slow,the liver coefficient ratio was increased,the liver color was reddish brown,some liver lobule boundaries were unclear,a small number of liver cells were loosely arranged,the contents of ALT,AST,LDH,AKP,and ALB were signif-icantly increased,the mRNA levels of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6,and CYP2C9 were significantly reduced,and the protein expres-sions of CYP2E1,CYP3A11,CYP1A2,and CYP2D6 were significantly reduced(all P＜0.05 or P＜0.01),but there was no statistical difference in the mRNA and protein expression of CYP2C19,and the pro-tein expression of CYP2C9(P＞0.05).Compared with the blank group,the mortality rate of nude mice in the cisplatin group was 35.7％,the growth state was poor,the diet,action,and mental state were low,the weight gain was less,the liver coefficient ratio was significantly increased,the liver color was dark red,the liver sinusoids and central veins were congested,the hepatocytes were disordered,the nuclei were consolidated and contracted,and the arrangement was loose,the contents of ALT,AST,LDH,AKP,and ALB were significantly increased,and the mRNA and protein expressions of CYP2E1,CYP3A11,CYP2C19,CYP1A2,CYP2D6,and CYP2C9 were significantly reduced(all P＜0.05 or P＜0.01).CONCLUSION:The dose of Brucea javanica bitter alcohol is correlated with hepatotoxicity to nude mice.High doses of Brucea javanica bitter alcohol have hepatotoxicity to nude mice,which may be re-lated to reducing serum levels of ALT,AST,LDH,AKP,and ALB,inhibiting the expression of multiple subtypes of enzymes in the key enzyme CYP450 of liver drug metabolism,and then reducing the me-tabolism of toxic substances.

Objective:With the aggravation of population aging, the burden of malignant tumors in the elderly population is becoming more and more heavy. This study aims to analyze the incidence and mortality of malignant tumors in the elderly population in Hebei Province in the past decade.Methods:The incidence and mortality data of malignant tumors in people aged ≥60 years old in 38 cancer registration areas in Hebei Province from 2011 to 2020 were collected, and the incidence and mortality were analyzed by gender, urban and rural areas, and age groups. The age standardized rates were calculated using the 2000 Chinese population census and Segi′s world population. The trend of incidence and mortality was analyzed using the Joinpoint model and the average annual percent change (AAPC).Results:From 2011 to 2020, 216 200 new cases of malignant tumors were reported in the elderly population in the cancer registration areas of Hebei Province, and 170 700 deaths were reported. The peak ages of incident cases number for males and females were 65-69 years old and 60-64 years old, respectively. The crude incidence rate of malignant tumors in the elderly was 905.42/10 5, and the crude mortality rate was 714.96/10 5. In general, the incidence and mortality in rural areas were higher than those in urban areas, and the incidence and mortality in males were higher than those in females. The peak ages of incidence and mortality were 80-84 years old and 85+ years old, respectively. From 2011 to 2020, lung cancer, gastric cancer, esophageal cancer, female breast cancer, and colorectal cancer were the main malignant tumors of incidence rate in the elderly population in Hebei Province, and lung cancer, gastric cancer, liver cancer, esophageal cancer, and colorectal cancer were the main malignant tumors in the mortality rate. From 2011 to 2020, the incidence and mortality of malignant tumors in the elderly population in Hebei Province showed a decreasing trend, and AAPC for the age-standardized incidence and mortality were -4.69% and -5.53%, respectively. The rank of incidence and mortality rate of each cancer had changed, but the top two were still lung cancer and stomach cancer. Conclusions:The incidence and mortality of cancer in the elderly population in Hebei province have decreased, but the burden is still heavy. Lung cancer and stomach cancer are still the focus of prevention and treatment in the elderly population in Hebei province.

Chronic kidney disease(CKD)is a chronic disease characterized by renal structural damage and dysfunction.At present,there is still a lack of effective therapeutic drugs and prevention and treatment methods for CKD in clinical practice.More and more studies have shown that necroptosis,as a new type of programmed cell death,plays a vital role in the onset and progression of CKD.Targeting key molecules in the necroptosis pathway,such as RIPK1,RIPK3 and MLKL,the development of small molecule inhibitors has become an emerging strategy for the treatment of CKD,and has shown significant potential to pro-tect the kidneys and alleviate renal fibrosis in a variety of in vitro and in vivo models.Therefore,this article summarizes the re-search progress of the mechanism of necroptosis in recent years,and focuses on the potential role of necroptosis in the pathogene-sis of CKD and the therapeutic potential of targeting this path-way,providing a new perspective and research direction for the prevention and treatment of CKD in the future.

Objective:To analyze the human immunodeficiency virus (HIV) screening status and the resulting residual risk (RR) among blood donors across 17 provincial blood centers in China.Methods:This study used a cross-sectional study. Data on HIV infection markers per 100 000 first-time donors (FD) and repeat donors (RD) from January 2015 to December 2024 were extracted from the National Blood Establishment Performance Comparison Information Management System. Questionnaires were used to collect each center′s HIV screening strategy, algorithm, serological test (ST) kit manufacturers, gray-zone setting for ST, and nucleic acid test (NAT) modality, method, and platform. The incidence-window-period model was used to calculate the residual risk for first-time donors (RR FD), repeat donors (RR RD), and total donors (RR TD) at each center. Horizontal and vertical analysis of RR FD, RR RD, and RR TD across centers and years were performed. Results:All 17 centers applied the same HIV screening strategy which was two rounds of ST followed by one round of NAT. Eight of them operated a single screening algorithm, six employed two algorithms and three used three. Eleven centers used both imported and domestic ST kits, five relied on domestic ST kits only, and one used imported ST kits only, while four centers never set a grey zone for ST throughout the decade. For NAT modalities, eight centers adopted both individual nucleic acid test (ID-NAT) and minipool nucleic acid test (MP-NAT), eight used MP-NAT only and one used ID-NAT only. Seven centers combined transcription mediated amplification (TMA) and polymerase chain reaction (PCR), nine used PCR only and one used TMA only, and fourteen centers ran both imported and domestic NAT systems, two used imported systems only and one used a domestic system only. Over the ten-year period, the mean RR FD across the centers ranged from 2.22 to 12.33 per 10 6 person-years, RR RD from 0.83 to 3.29 per 10 6 person-years and RR TD from 1.59 to 9.29 per 10 6 person-years, with center Z4 consistently showing the lowest values for all three metrics and center U4 recording the highest RR FD and RR TD, while center D2 had the highest RR RD. In 2024 compared with 2015, eleven centers achieved a lower RR FD and ten centers achieved lower RR RD and RR TD. The RR FD and RR TD of centers W2 and U4 displayed pronounced fluctuations and an upward trend in recent years. Conclusions:The 17 provincial blood centers maintain consistent HIV screening strategies, while demonstrating variations in screening algorithm, ST kit manufacturers, NAT modalities, methods, and platform. And the RR FD, RR RD, and RR TD differ across centers. Although most centers show declining trend in RR over the ten-year period, some centers exhibite data fluctuations with a rising trend, suggesting potential for further optimization of HIV screening protocols.

[Purpose]To analyze the incidence,mortality and disease burden of malignant tumors in the cancer registration areas of Hebei Province in 2020.[Methods]The incidence and mortality data of cancer in 2020 were collected from the cancer registries of Hebei Province,and the quality of data was evaluated.The crude incidence(mortality)rate,age-specific incidence(mortality)rates and age-standardized incidence(mortality)rates by Chinese standard population(ASIRC/ASMRC)and world standard population(ASIRW/ASMRW)were calculated and analyzed.The disability-ad-justed life years(DALY)were calculated and analyzed according to the Excel disease burden cal-culation template recommended by the World Health Organization(WHO).[Results]In 2020,the crude incidence rate,ASIRC,ASIRW of malignant tumors in the cancer registration areas of Hebei Province were 229.36/105,147.06/105 and 143.74/105,respectively.The incidence rate in men was higher than that in women.The incidence rates in urban and rural areas were 230.26/105 and 228.84/105,and the age-standardized incidence rates reached a peak in the age group of 80～84 years old.The crude mortality rate,ASMRC,ASMRW were 146.38/105,85.33/105 and 84.79/105,respectively.The mortality rate in men was higher than that in women.The age-standardized mor-tality rate rose with age,reaching a peak in the age group of 85+years old,and the crude mortality rates in urban and rural areas were 143.82/105 and 147.84/105,respectively.The DALY of ma-lignant tumors in the cancer registration areas of Hebei Province were 345 030 person-years,reaching a maximum in the age group of 45～59 years old,with a DALY rate of 15.00/103,and the highest in the age group of 70～79 years old.Lung cancer had the heaviest disease burden,with DALY of 83 684 person-years,accounting for 24.25％of all malignant tumors,followed by stomach,liver,female breast,and colorectal cancers.The DALY in urban and rural areas were 122 062 and 222 993 person-years,respectively,and the trends in DALY rates were basically stable.[Conclusion]The disease burden of malignant tumors in Hebei Province is relatively heavy,cancer prevention and control should be further strengthened and focused on urban men and the elderly to reduce disease burden of malignant tumors in the future.

Enhanced recovery after surgery (ERAS) is a series of perioperative optimization measures based on evidence-based medicine aimed at achieving rapid recovery. Existing studies have shown that ERAS can effectively reduce surgical stress, decrease the incidence of complications, shorten hospital stays, save medical costs, and improve patient satisfaction. Although lung transplantation techniques have become increasingly mature, lung transplant recipients still have a high incidence of complications during perioperative period. To further improve the perioperative survival rate of lung transplant recipients, introducing ERAS concept into the perioperative management strategy of lung transplantation is of great significance for reducing incidence of perioperative complications, promoting rapid recovery and long-term survival of lung transplant recipients. This article discusses the advances in application of ERAS concept in the perioperative management of lung transplantation, aiming to provide references for optimizing the perioperative management of lung transplant recipients and reducing perioperative complications.

Alcoholic liver disease(ALD), a major cause of chronic liver disease worldwide, poses a serious threat to human health. Despite the availability of various drugs for treating ALD, their efficacy is often uncertain, necessitating the search for new therapeutic approaches. Traditional Chinese medicine polysaccharides have garnered increasing attention in recent years due to their versatility, high efficiency, and low side effects, and they have demonstrated significant potential in preventing and treating ALD. Emerging studies have suggested that these polysaccharides exert their therapeutic effects through multiple mechanisms, including the inhibition of oxidative stress and the regulation of lipid metabolism, gut microbiota, and programmed cell death. This review summarizes the recent research progress in the pharmacological effects and regulatory mechanisms of traditional Chinese medicine polysaccharides in treating ALD, aiming to provide a scientific basis and theoretical support for their application in the prevention and treatment of ALD.
