Ferroptosis of chondrocytes is a significant contributor to osteoarthritis (OA), for which there is still a lack of safe and effective therapeutic drugs targeting ferroptosis. Here, we screen for anti-ferroptotic drugs in Food and Drug Administration (FDA)-approved drug library via a high-throughput manner in chondrocytes. We identified a group of FDA-approved anti-ferroptotic drugs, among which vitamin K showed the most powerful protective effect. Further study demonstrated that vitamin K effectively inhibited ferroptosis and alleviated the extracellular matrix (ECM) degradation in chondrocytes. Intra-articular injection of vitamin K inhibited ferroptosis and alleviated OA phenotype in destabilization of the medial meniscus (DMM) mouse model. Mechanistically, transcriptome sequencing and knockdown experiments revealed that the anti-ferroptotic effects of vitamin K depended on growth arrest-specific 6 (Gas6). Furthermore, exogenous expression of Gas6 was found to inhibit ferroptosis through the AXL receptor tyrosine kinase (AXL)/phosphatidylinositol 3-kinase (PI3K)/AKT serine/threonine kinase (AKT) axis. Together, we demonstrate that vitamin K inhibits ferroptosis and alleviates OA progression via enhancing Gas6 expression and its downstream pathway of AXL/PI3K/AKT axis, indicating vitamin K as well as Gas6 to serve as a potential therapeutic target for OA and other ferroptosis-related diseases.

Objective To compare the midterm outcomes of the Bentall procedure versus isolated aortic valve replacement(AVR)in patients with bicuspid aortic valve(BAV)complicated with severe stenosis and ascending aortic dilation in order to assess the therapeutic value of these surgical approaches for this complex cardiac condition.Methods A retrospective cohort study was conducted on 96 eligible patients who underwent surgical treatment in our institute between January 2018 and December 2022.According to surgical approaches,they were divided into an AVR group(65 cases)and a Bentall group(31 cases).Demographic features,comorbidities,preoperative status,and echocardiographic parameters were collected in all patients.Propensity score matching(PSM)was applied in a 1:1 ratio to balance baseline characteristics.Perioperative indicators and follow-up data were compared and analyzed between matched cohorts after control of cofounding factors.Results After PSM,25 matched pairs were screened out and analyzed with comparable baseline data(all P>0.05).The Bentall group demonstrated significantly more superior intraoperative effective orifice area(EOA,2.69±0.47 vs 2.35±0.47 cm2,P=0.013)and EOA index(EOAI,1.69±0.30 vs 1.47±0.29 cm2/m2,P=0.010),and obviously longer cardiopulmonary bypass time[190.00(147.00,257.00)vs 101.00(88.50,124.50)min,P<0.01]and aortic cross-clamp time[141.00(120.00,166.00)vs 66.00(55.00,81.50)min,P<0.01]when compared with the AVR group.During a median follow-up of 28 months,the AVR group had notably larger aortic sinus diameter[32.00(30.00,34.00)vs 26.80(26.00,28.00)mm,P<0.01]and ascending aortic diameter[38.00(34.50,42.00)mm vs 26.00(26.00,28.00)mm,P<0.01],with ongoing dilation in the ascending aorta,while the Bentall group maintained stable dimensions.The Bentall group also showed statistically lower peak aortic valve pressure gradients[21.00(15.50,27.00)vs 25.00(19.50,31.00)mmHg,P=0.049].Conclusion Both Bentall procedure and AVR are effective in treatment of BAV complicated with severe stenosis and ascending aortic dilation.But,Bentall procedure offers advantages in hemodynamic optimization and aortic stability.

ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone （TD） regimen in the treatment of newly diagnosed multiple myeloma （NDMM） with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st， 2015 to July 31th， 2019 were retrospectively analyzed， and they were divided into a control group （bortezomib/dexamethasone-containing regimen， 27 cases） and an observation group （cinobufagin tablets combined with TD regimen， 23 cases）. The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate， one-year and two-year overall survival rate， and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow， hemoglobin， β2-microglobulin， lactate dehydrogenase， serum creatinine， blood urea nitrogen， bone pain score， and KPS functional status score （KPS score） before and after treatment. ResultsIn terms of clinical efficacy， there was no statistically significant difference （P＞0.05） in the overall response rate ［the observation group 69.57%（16/23） vs the control group 70.37% （19/27）］ and deep remission rate ［the observation group 56.52% （13/23） vs the control group 55.56% （15/27）］ between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%， and the two-year overall survival rates were 81.8% and 80.9% respectively， with no statistically significant differences between groups （P＞0.05）. During the treatment， no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%， which was lower than 48.15% in the control group （P＜0.01）. After the treatment， the proportion of myeloma plasma cells， β2-microglobulin， serum creatinine level， and bone pain score decreased， while the hemoglobin level and KPS score increased in both groups （P＜0.05 or P＜0.01）. Compared between groups after treatment， the bone pain score of the observation group was lower than that of the control group， while the KPS score was higher than that of the control group （P＜0.05）. ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen， but the former is more helpful in relieving the pain and improving the quality of life， and has better safety.

Purpose/Significance To analyze the technical situation of patent owners in the field of clinical decision support system(CDSS)in China as a whole,so as to provide references for CDSS related technical research.Method/Process Firstly,the CDSS patent data are analyzed from the aspects of application trend,patent disclosure,technology field distribution,etc.,then the patentees are di-vided into different categories,and their technical concerns are analyzed by word frequency and interword vector.Finally,the technology correlation and patent exclusives are analyzed based on the active patentees.Result/Conclusion The number of CDSS patent disclosure shows an overall increasing trend.This field has not formed a technological monopoly in China.Government departments and research in-stitutions should pay attention to the possible financial risks.

Objective To observe the clinical efficacy of Redo-Bentall surgery in the reoperation of aortic root lesions.Methods A retrospective analysis was performed on 46 patients who underwent Redo-Bentall surgery for aortic root lesions in our department from June 2010 to April 2022.They were 35 males and 11 females,at a mean age of 43.37±12.79 years,in 4.96±6.76 years since the last operation.General clinical data in perioperative period and during follow-up were collected and analyzed.Kaplan-Meier survival analysis was used to compare the survival rates of each etiological group.Results There were 9 cases of central end otitis,12 cases of Behset's disease,and 25 cases of other causes.After operation,4 cases(8.70％)experienced cardiac arrest,4 cases(8.70％)renal failure,2 cases(4.35％)gastrointestinal bleeding,2 cases(4.35％)new third-degree atrioventricular block and 2 cases(4.35％)permanent pacemaker placement.In perioperative period,3 cases(6.52％)died in hospital.During a mean follow-up of 5.03±3.27 years after discharge,5 cases(11.63％)were lost to follow-up,1 case died(2.33％),1 case had lacunar infarction(2.33％),and no severe bleeding or embolism complications was observed in the rest patients.The long-term survival rate was significantly lower in the endocarditis group(62.3％)and the Behcet's disease group(70％)than the other etiological groups(80％,P＜0.05).Conclusion The application of Redo-Bentall in the reoperation of aortic root lesions is safe and effective,but the survival rate is quite lower in the patients with infective endocarditis and Behcet's disease.
