OBJECTIVE From the perspective of China’s health system， to evaluate the economic efficiency of Irinotecan liposome+fluorouracil+calcium folinate+oxaliplatin（NALIRIFOX regimen） versus paclitaxel （albumin-bound） combined with gemcitabine （AG regimen） in the first-line treatment of metastatic pancreatic cancer. METHODS A dynamic Markov model was constructed based on the data from the NAPOLI 3 clinical trial， with a cycle period of 28 days and a simulation time limit of 5 years. Incremental cost-effectiveness ratio （ICER） and quality-adjusted life year （QALY） were used as the model output indicators. The willingness-to-pay （WTP） threshold was set at three times China’s 2024 per capita gross domestic product （GDP）， and a discount rate of 5% was adopted. A cost-utility analysis was conducted to analyze the economic efficiency of the NALIRIFOX regimen compared to the AG regimen. Univariate sensitivity analysis and probabilistic sensitivity analysis were used to evaluate the robustness of the model results， and scenario analysis was conducted by reducing the cost of irinotecan liposome by 60% and 70%. RESULTS The base-case analysis showed that the ICER of the NALIRIFOX regimen was 854 669.96 yuan/QALY compared to the AG regimen， which was greater than the WTP threshold （287 247 yuan/QALY）， indicating that the NALIRIFOX regimen was not economically efficient. The univariate sensitivity analysis results indicated that the discount rate， the cost of irinotecan liposome， the utility value of the progression-free survival state， and the utility value of the disease progression state had a significant impact on the ICER. The probabilistic sensitivity analysis results showed that under the WTP threshold of this study， the NALIRIFOX regimen was not economically efficient compared with the AG regimen. The scenario analysis results indicated that when the price was reduced by 70%， the probability of the NALIRIFOX regimen being economically efficient compared with the AG regimen was 9.60%. CONCLUSIONS From the perspective of China’s health system， when the WTP threshold is set at three times China’s 2024 per capita GDP， the NALIRIFOX regimen is not economically efficient in the first-line treatment of metastatic pancreatic cancer， compared with the AG regimen.

Objective To investigate the effects of icariin on high glucose-induced autophagy and apoptosis of podocytes,and the regulating effects on mammalian target of rapamycin(mTOR)/serine-threonine kinase(Akt)/cyclic adenosine monophosphate response element binding protein(CREB)pathway.Methods The mouse podocytes MPC5 were taken and divided into five groups:normal control group(5.5 mmol·L-1 glucose),high glucose group(30 mmol·L-1 glucose),icariin group(30 mmol·L-1glucose+5 μmol·L-1icariin),GDC-0349 group(30 mmol·L-1glucose+50 μmol·L-1 GDC-0349),icariin+GDC-0349 group(30 mmol·L-1 glucose+5 μmol·L-1 icariin+50 μmol·L-1 GDC-0349).Cultured for 48 hours,the tetramethylazozolium salt method was used to detect the viability of MPC5 cells;acridine orange staining was used to observe the autophagy of MPC5 cells;apoptosis of MPC5 cells was detected by flow cytometry;Western blotting was used to detect the expression of autophagy[microtubule associated protein one light chain 3(LC3)II,LC3Ⅰ,autophagy-related protein(Beclin-1)],apoptosis[Bcl-2 related X protein(Bax),B cell lymphoma-2(Bcl-2)]and mTOR/Akt/CREB pathway-related proteins of MPC5 cells.Results Compared with the normal control group,the cell viability,expression levels of Bcl-2,phosphorylated mTOR(p-mTOR)/mTOR,phosphorylated Akt(p-Akt)/Akt,phosphorylated CREB(p-CREB)/CREB protein of MPC5 cells in the high glucose group were significantly decreased(P＜0.05),the autophagy ability was enhanced,the autophagosome showed orange fluorescence,and the apoptosis rate,LC3Ⅱ/LC3Ⅰ,Beclin-1,Bax protein expression levels were significantly increased(P＜0.05).Compared with the high glucose group,the cell viability,LC3Ⅱ/LC3Ⅰ,Beclin-1,Bcl-2,p-mTOR/mTOR,p-Akt/Akt,p-CREB/CREB protein expression levels of MPC5 cells in icariin group were significantly increased,the autophagy ability was further enhanced,the number of autophagosomes was increased,the autophagosomes showed brick red fluorescence(P＜0.05),the apoptosis rate and Bax protein expression level were significantly decreased(P＜0.05),and the cell viability,LC3Ⅱ/LC3Ⅰ,Beclin-1,Bcl-2,p-mTOR/mTOR,p-Akt/Akt and p-CREB/CREB proteins expression levels of MPC5 cells in GDC-0349 group were significantly decreased,the autophagy ability was weakened,the number of autophagosomes was reduced,the autophagosomes showed orange fluorescence(P＜0.05),and the apoptosis rate and Bax protein expression level were significantly increased(P＜0.05);icariin+GDC-0349 could reverse the effect of icariin on high glucose induced MPC5 cells(P＜0.05).Conclusion Icariin promotes elevated glucose-induced podocyte autophagy and inhibits apoptosis by activating the mTOR/Akt/CREB pathway.

Objective To investigate the role and related mechanism of the soluble guanylate cyclase(sGC)-cGMP-protein kinase G(PKG)signaling pathway in the amelioration of isoproterenol(ISO)-induced cardiac hypertrophy in mice by aqueous extract of Curcuma kwangsiensis root tubers(GYJS).Methods 72 KM male mice were divided randomly into 6 groups:normal,model,propranolol control(40 mg/kg),and GYJS low-(1 g/kg),medium-(2 g/kg),and high-dose(4 g/kg)groups.Mice in the experimental groups were injected subcutaneously with ISO 10 mg/kg on days 1～3 and ISO 5 mg/kg on days 4～14 to establish a mouse cardiac hypertrophy model.4h after each subcutaneous injection of ISO,the mice in each group were administered the corresponding drugs orally for a dosing cycle of 14 days.The hearts were then removed and whole heart and left ventricle weight were measured.Myocardial tissue pathology was observed using hematoxylin and eosin and Masson staining,and sGC subunit beta-1(GUCY1B3)and transforming growth factor(TGF-β1)were detected by immunohistochemistry.Serum lactate dehydrogenase(LDH),creatine kinase(CK),and Nitric Oxide(NO),and myocardial superoxide dismutase(SOD)activity and malondialdehyde(MDA)content were measured using respective kits.Serum cGMP was detected by enzyme-linked immunosorbent assay and quantitative reverse transcription PCR(RT-qPCR),and atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),GUCY1B3,PKG Ⅰ,and phosphodiesterase(PDE)5A mRNA expression levels were also determined by RT-qPCR.Results Compared with the model group,whole heart and left ventricle weights were significantly reduced in mice treated with propranolol or GYJS(P＜0.001 or P＜0.0001)and myocardial hypertrophy and myocardial fibrosis were significantly reversed.All the treatments significantly elevated myocardial expression of GUCY1B3(P＜0.05 or P＜0.01)and significantly reduced expression of TGF-β1(P＜0.05 or P＜0.01).The myocardial damage markers LDH and CK were significantly reduced(P＜0.05 or P＜0.01)while NO and cGMP were significantly elevated(P＜0.05 or P＜0.01),the myocardial oxidative stress indicator MDA was significantly reduced(P＜0.05 or P＜0.01)and SOD activity was significantly increased(P＜0.05 or P＜0.01).mRNA levels of the myocardial hypertrophy markers ANP,BNP,and PDE5A were significantly reduced(P＜0.05,P＜0.01,or P＜0.001)and the mRNA levels of GUCY1B3 and PKG Ⅰ were significantly increased(P＜0.01 or P＜0.001).Conclusions GYJS may improve cardiac hypertrophy by modulating the sGC-cGMP-PKG signaling pathway.

Objective:To systematically assess the effectiveness and safety of acupuncture for spastic hemiplegia after ischemic stroke. Methods:Randomized controlled trials(RCTs)of acupuncture treatment for spastic hemiplegia after ischemic stroke meeting the inclusion criteria in Cochrane Library,Medline,Excerpta Medica Database(EMBASE),PubMed,China National Knowledge Infrastructure(CNKI),SinoMed,Chongqing VIP Database(VIP),and Wanfang Data Knowledge Service Platform(Wanfang)published from each database's inception to February 2023 were retrieved by computer.Two reviewers independently extracted data and evaluated the risk of bias using Cochrane's risk of bias tool.Review Manager 5.4 was used for data analysis.Continuous data were evaluated using mean difference(MD)with a 95%confidence interval(CI),and dichotomous data were analyzed using risk ratio(RR). Results:A total of 24 trials,including 1 970 participants,were included in the study.The meta-analysis of 7 trials showed that compared to the rehabilitation therapy,acupuncture therapy was more effective in improving the simplified Fugl-Meyer assessment score after 1-month treatments[MD=10.52,95%CI(7.81,13.23),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.18,95%CI(11.34,27.02),P<0.001],and the 6-month treatment course resulted in better outcomes than the 1-month course.The meta-analysis of 8 trials showed that acupuncture had a better improvement on the Barthel index score than rehabilitation therapy after 1-month treatments[MD=10.78,95%CI(8.91,12.64),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.94,95%CI(19.02,20.87),P<0.001],and the 6-month course was better than the 1-month course.The meta-analysis of 2 trials showed that the effective rate of the modified Ashworth scale score improvement was more notable in the acupuncture group after 1-month treatments[RR=1.20,95%CI(1.02,1.40),P=0.020].One trial reported no adverse event,and 1 trial reported 3 adverse events without severe influence. Conclusion:Acupuncture might be an effective and safe therapy for spastic hemiplegia after ischemic stroke,but more high-quality,large-sample objectively-evaluated RCTs are needed to validate the conclusion.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

The clinical utilization of doxorubicin (Dox) in various malignancies is restrained by its major adverse effect: irreversible cardiomyopathy. Extensive studies have been done to explore the prevention of Dox cardiomyopathy. Currently, ferroptosis has been shown to participate in the incidence and development of Dox cardiomyopathy. Sorting Nexin 3 (SNX3), the retromer-associated cargo binding protein with important physiological functions, was identified as a potent therapeutic target for cardiac hypertrophy in our previous study. However, few study has shown whether SNX3 plays a critical role in Dox-induced cardiomyopathy. In this study, a decreased level of SNX3 in Dox-induced cardiomyopathy was observed. Cardiac-specific Snx3 knockout (Snx3-cKO) significantly alleviated cardiomyopathy by downregulating Dox-induced ferroptosis significantly. SNX3 was further demonstrated to exacerbate Dox-induced cardiomyopathy via induction of ferroptosis in vivo and in vitro, and cardiac-specific Snx3 transgenic (Snx3-cTg) mice were more susceptible to Dox-induced ferroptosis and cardiomyopathy. Mechanistically, SNX3 facilitated the recycling of transferrin 1 receptor (TFRC) via direct interaction, disrupting iron homeostasis, increasing the accumulation of iron, triggering ferroptosis, and eventually exacerbating Dox-induced cardiomyopathy. Overall, these findings established a direct SNX3-TFRC-ferroptosis positive regulatory axis in Dox-induced cardiomyopathy and suggested that targeting SNX3 provided a new effective therapeutic strategy for Dox-induced cardiomyopathy through TFRC-dependent ferroptosis.

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine and metabolic disease, and its pathogenesis is closely related to inflammation, insulin resistance, and metabolic disorders. Bilirubin is the final product of the destruction and degradation of senescent red blood cells in the body. In addition, bilirubin can be not only used to evaluate liver function damage and cytotoxicity, but also can anti-inflammatory, antioxidant, alleviate metabolic disorders, etc. Recently, studies have found a certain correlation between low levels of bilirubin and PCOS: the level of bilirubin in patients with PCOS is low, and the anti-inflammatory and antioxidant properties of bilirubin may play a protective role in the pathogenesis of PCOS.

Objective:To investigate the efficacy of Xiaoshuan Changrong Capsules combined with donepezil hydrochloride in the treatment of patients with vascular dementia and their effects on serum cytokines and oxidative stress. Methods:A total of 102 patients with vascular dementia who received treatment in Hangzhou Seventh People's Hospital, China between January 2019 and January 2021 were included in this study. They were randomly divided into control and observation groups, with 51 patients per group. The control group was treated by oral donepezil hydrochloride. The observation group was given oral Xiaoshuan Changrong Capsules combined with oral donepezil hydrochloride. All patients were treated for 12 weeks. Efficacy was compared between the two groups. The Clinical Dementia Rating score, the Mini-Mental State Examination score, and serum levels of interleukin 6, insulin-like growth factor-1, tumor necrosis factor-α, superoxide dismutase and malondialdehyde were compared between before and after treatment. Results:Total response rate in the observation group was significantly higher than that in the control group [90.20% (46/51) vs. 70.59% (36/51), χ 2 = 6.22, P < 0.05]. At 12 weeks after treatment, the Clinical Dementia Rating score in the observation group was significantly lower than that in the control group [(1.34 ± 0.27) points vs. (1.89 ± 0.31) points, t = 9.55, P < 0.05]. At 12 weeks after treatment, the Mini-Mental State Examination score in the observation group was significantly higher than that in the control group [(25.45 ± 1.98) points vs. (22.32 ± 2.10) points, t = 7.74, P < 0.05]. At 12 weeks after treatment, interleukin-6, insulin-like growth factor-1, and tumor necrosis factor-α levels in the observation group were (31.28 ± 7.35) ng/L, (0.34 ± 0.08) ng/L and (9.46 ± 2.27) ng/L, respectively, which were significantly lower than those in the control group [(46.43 ± 6.28) ng/L, (0.48 ± 0.07) ng/L, (20.98 ± 3.56) ng/L, t = 11.19, 9.40, 19.48, all P < 0.05]. At 12 weeks after treatment, superoxide dismutase in the observation group was significantly higher than that in the control group [(98.91 ± 7.25) U/L vs. (86.59 ± 5.63) U/L, t = 9.58, P < 0.05] . At 12 weeks after treatment, malondialdehyde in the observation group was significantly lower than that in the control group [(3.25 ± 0.50) mmol/L vs. (4.81 ± 0.35) mmol/L, t = 18.25, P < 0.05]. Conclusion:Xiaoshuan Changrong Capsules combined with donepezil hydrochloride is highly effective on vascular dementia. It can reduce cellular inflammatory response and improve oxidative stress response. This study is of great innovation and science.
