Objective:To evaluate the feasibility of transjugular transcatheter tricuspid valve replacement (TTVR) using the LuX-Valve Plus system (Ningbo Jenscare Scientific, China) for the treatment of severe tricuspid regurgitation in real-world clinical settings.Methods:This prospective study enrolled 81 patients with severe ricuspid regurgitation (≥3+) who underwent TTVR with the LuX-Valve Plus system at the Department of Cardiology, West China Hospital of Sichuan University between May 2022 and March 2024. Among them, 44 patients were from a compassionate-use study, and 37 were from two premarket clinical trials. Baseline clinical data, preprocedural imaging, procedural outcomes, and postprocedural follow-up data were collected. The primary endpoint events included device success, procedural success, and 30 d composite adverse events.Results:The age of the cohort was (74.5±7.8) years, with 54 females (67%). Device success and procedural success rates were both 90% (73/81). Post-procedural tricuspid regurgitation improved, with a 6% (5/81) incidence of moderate-to-severe paravalvular leakage. The rate of permanent pacemaker implantation was 12% (10/81), of which 5% (4/81) had pre-existing indications for pacemaker implantation. Major bleeding events occurred in 10% (8/81) of patients, and the 30 d composite endpoint rate was 25% (20/81).Conclusion:TTVR using the LuX-Valve Plus system demonstrates promising feasibility for high-risk surgical patients with severe tricuspid regurgitation, effectively reducing or eliminating regurgitation with acceptable safety. However, challenges remain in reducing risks of major adverse events, including permanent pacemaker implantation and severe bleeding.

Objective:To explore the correlation between serum nidogen-2 (NID-2) and thoracic aortic calcification in patients with chronic kidney disease (CKD), and construct a risk prediction model based on NID-2 to evaluate its value in predicting the risk of the severe thoracic aortic calcification and cardiovascular and cerebrovascular events in CKD patients.Methods:It was a prospective cohort study. Patients with CKD at stage 3 to 5D in the Zhongda Hospital Affiliated to Southeast University from January 2022 to January 2023 were enrolled. Syngo.via software was used to evaluate the volume of thoracic aortic calcification, and enzyme-linked immunosorbent assay was employed to determine the level of serum NID-2. According to the volume of thoracic aortic calcification, the patients were divided into three groups: no calcification group, mild calcification group and severe calcification group. The top 25% of the patients were defined as no or mild calcification group, and the latter 75% were defined as severe calcification group. The follow-up period was one year. During the follow-up period, cardiovascular and cerebrovascular events, as well as all-cause death among the enrolled patients were recorded. Logistic regression analysis was used to screen the influencing factors of thoracic aortic calcification. Based on the results of logistic regression analysis, a nomogram prediction model was constructed. The receiver operating characteristic curve (ROC curve), calibration curve, and decision curve were employed to evaluate the discrimination, calibration and clinical practicality of the nomogram model.Results:A total of 132 patients were included, with 91 males (68.94%) and age of (56.51±16.37) years. There were 60 CKD 3-5 stage patients (non-dialysis, 45.45%) and 72 CKD 5D patients (dialysis, 54.55%). Serum ND-2 levels differed significantly among healthy individuals, dialysis patients and non-dialysis patients ( H=70.651, P<0.001). There was no statistically significant difference in serum NID-2 level between the no or mild calcification group and the severe calcification group in dialysis patients ( Z=350.00, P=0.426). The serum NID-2 level in the severe calcification group was significantly higher than that in the no or mild calcification group in non-dialysis patients ( Z=242.00, P=0.019). In non-dialysis patients, there was a statistically significant correlation between serum NID-2 level and volume of thoracic aortic calcification ( r=0.40, P<0.001). In dialysis patients, there was no statistically significant correlation between serum NID-2 level and volume of each segment of thoracic aortic calcification (all P>0.05). The univariate logistic regression analysis showed that, age, hemoglobin, serum albumin, estimated glomerular filtration rate, NID-2, hypertension, type 2 diabetes mellitus and cerebral infarction were correlated factors of thoracic aortic calcification in non-dialysis patients (all P<0.05). Multivariate logistic regression analysis showed that age ( OR=1.22, 95% CI 1.08-1.50, P=0.010) was an independent correlated factor of thoracic aortic calcification in non-dialysis patients. The above related variables of univariate logistic regression analysis were incorporated into a nomogram to construct a predictive model for severe vascular calcification in non-dialysis patients, yielding an AUC of 0.94 (95% CI 0.89-0.99) in ROC curve, with a sensitivity of 83% and a specificity of 95%. A nomogram model based on above variables for predicting cardiovascular and cerebrovascular events in non-dialysis patients demonstrated an AUC of 0.95 (95% CI 0.90-1.00) in ROC curve, with a sensitivity of 95% and a specificity of 87%. Conclusions:In non-dialysis patients, serum NID-2 level in the severe calcification group is significantly higher than that in the no or mild calcification group. The serum NID-2 is a related factor of thoracic aortic calcification and cardiovascular and cerebrovascular events in non-dialysis patients. The nomogram prediction model constructed by combining NID-2 with age, hemoglobin, serum albumin, estimated glomerular filtration rate, hypertension, type 2 diabetes mellitus and cerebral infarction has a high predictive value for the risk of thoracic aortic calcification as well as cardiovascular and cerebrovascular events in non-dialysis patients.

Objective:To establish a prediction method of diopter based on sequence of ocular biological parameters.Methods:A stratified random cluster sampling method was used to extract the dataset. The dataset consisted of data collected from January 2022 to January 2023 by the Eye & ENT Hospital, Fudan University, from children aged 5 to 13 years in 2 key schools and 2 general schools of Yangpu District, Shanghai. Children’s ocular biological parameters, including sex, age, diopter, axial length, corneal curvature, and anterior chamber depth were collected. The slope of the optimally fitted straight line was calculated using the least squares method. The least square-back propagation (BP) neural network model was established by combining baseline data and the pre-processed rate of the change of ocular biological parameters. The dataset was divided into the training set and the validation set according to the ratio of 8:2 for five-fold cross-validation. The model performance was evaluated by using the mean absolute error (MAE), mean squared error (MSE), root mean square error (RMSE), correlation coefficient R, and coefficient of determination R2. Results:The optimal performances of R2, R, RMSE, MAE, and MSE of the least square-BP neural network model were 0.96, 0.981 9, 0.214 2, 0.139 9 D, 0.045 9, respectively. The regression equation between the predicted value and the true value of the diopter was y=0.97 x+ 0.014 8, R2=0.97, with good correlation. In the internal verification, MAE values of the diopter at three, six, nine, and twelve months of follow-up were 0.110 1, 0.136 0, 0.153 7, and 0.184 8 D, respectively, which achieved clinically acceptable performance (less than 0.25 D). In the external validation, the errors were less than 0.25 D at all ages. Conclusions:A prediction method of diopter based on sequence of ocular biological parameters was successfully developed.

ObjectiveTo explore the possible mechanism of Bushen Huoxue Formula （补肾活血方， BHF） in the treatment of Parkinson's disease （PD） from the the perspective of intestinal flora. MethodsSeventy-two male C57/BL6J mice were randomly divided into blank group， model group， Madopar group and low-， medium- and high-dose BHF groups， with 12 mice in each group. The mice in the blank group were intraperitoneally injected with 10 ml/kg of normal saline， and those in the other groups were intraperitoneally injected with 30 mg/kg of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine （MPTP） at a concentration of 3 mg/ml to induce PD mice model， both once a day for 7 consecutive days. After successful modeling， the low-， medium-， and high-dose BHF groups were given 7.5， 15， and 30 g/（kg·d） of BHF by gavage， respectively， while the Madopar group was given 112.5 mg/（kg ·d） of Domedopar tablets by gavage， and the blank group and the model group were given 15 ml/（kg·d） of distilled water， all once a day for 14 consecutive days. The rod climbing test， rotating rod test， grip strength test and weight-bearing swimming test were used to evaluate the behavioral indicators of mice. Western blotting was used to measure the protein expression levels of Toll-like receptor （TLR）/nuclear factor kappa B （NF-κB） pathway inflammatory factors in the mouse ileum， including Toll-like receptor 2 （TLR2）， Toll-like receptor 4 （TLR4）， NF-κB， tumor necrosis factor α （TNF-α）， interleukin 6 （IL-6）， and interleukin 17 （IL- 17）. 16S rRNA high-throughput sequencing was used to analyze changes in mouse intestinal flora. ResultsCompared to those in the blank group， the mice in the model group had longer bottoming time when climbing the pole， reduced grip strength， shortened rotary pole duration and swimming duration， and increased protein expression levels of TLR2， TLR4， NF-κB， TNF-α， and IL-6 in the ileal tissue （P＜0.01）. Compared to the model group， the Madopar group and the low-， medium- and high-dose BHF groups had shortened bottoming time of the climbing pole and increased grip strength； the Madopar group and the high-dose BHF group had prolonged rotary pole duration， and reduced protein expressions of TLR2， TLR4， NF-κB， TNF-α， IL-6， and IL-17 levels； and only the high-dose BHF group had prolonged swimming duration （P＜0.05 or P＜0.01）. Compared to those in the low-dose BHF group， the bottoming time of the climbing pole were shorter in the moderate- and high-dose groups （P＜0.05 or P＜0.01）， and the grip strength increased while the protein expression levels of TLR2， TLR4 and IL-17 decreased in the high-dose group （P＜0.05 or P＜0.01）. The intestinal flora results showed significant differences between the blank group and the model group in the Dominance index， Pielou_e index， Shannon index， and Simpson index （P＜0.05 or P＜0.01）. Compared to those of the model group， the Shannon index， Chao1 index， and Observed_otus index of the Madopar group， as well as the Chao1 index， Observed_otus index， Dominance index， Pielou_e index， Shannon index， and Simpson index of the high-dose BHF group all showed significantly statistical differences （P＜0.05 or P＜0.01）. At the phylum level， the relative abundance categories of bacterial phyla with statistically significant differences in each group included Proteobacteria， Bacteroidetes， and Firmicutes （P＜0.05 or P＜0.01）. At the genus level， the relative abundance categories of bacterial genera with statistically significant diffe-rences among each group included Muribaculaceae， Akkermansia， and Helicobacter pylori （P＜0.05 or P＜0.01）. ConclusionThe possible mechanism of BHF in treating PD may be to reconstruct the disordered intestinal flora structure and improve the inflammatory response.

Objective To explore the effect of aerobic exercise on renal function abnormalities and mitochondrial oxidative stress of obese rats.Methods Ninety 5-week male Sprague-Dawley rats were randomly divided into a normal diet group(CON,n=10)and a high-fat diet group(n=80).The latter group was on high-fat diet for 8 weeks to induce obesity with renal function abnormality.After success-ful modelling,40 rats were chosen and randomly divided into a high-fat diet control group(HFD)and three groups of high-fat diet+aerobic exercise with different intensities(40%VO2max,60%VO2max,and 80%VO2max),each of 10.All exercise groups underwent daily 60-min aerobic exercise on treadmill,5 days per week for 4 weeks.After the intervention,their body weight,body length,perirenal and epi-didymal fat weights were measured,and morphometric indices including fat-body ratio and Lee's in-dex were calculated.Moreover,such biochemical indicators of renal function as serum creatinine(SCr),serum cystatin C and urinary microalbumin(mALB)were tested.Meanwhile,the pathological changes of the kidney were observed using hematoxylin eosin(HE)staining and Periodic acid-Schiff(PAS)staining,while the ultrastructural changes of the kidney and mitochondria were observed using the transmission electron microscopy.Moreover,the levels of superoxide dismutase(SOD),malondialde-hyde(MDA),and mitochondrial membrane potential in mitochondria were evaluated using ELISA kits.Results After 4 weeks of intervention,the average SCr,serum cystatin C,and mALB levels in the HFD group increased significantly compared with the CON group(P<0.05).Moreover,the average SCr levels of all exercise groups were significantly lower than the HFD group(P<0.05),with the average serum cystatin C and mALB levels of the 60%VO2max and 80%VO2max groups significantly lower than the HFD group(P<0.05).Meanwhile,the renal tubular epithelial cells in the HFD group showed mod-erate degeneration and increased glomerulosclerosis index(GSI)(P<0.05)and the degree of glomerular hypertrophy in each exercise group was significantly lower than the HFD group,with the renal tubules of the 60%VO2max group showing a clearer contour and decreased GSI(P<0.05).What's more,com-pared with the CON group,the number of swollen mitochondria in the HFD group increased,but the mitochondria damage of the 60%VO2max group relieved significantly compared with the HFD group.The renal mitochondrial MDA levels in the CON group increased significantly compared with the HFD group(P<0.05),and those of the exercise groups were significantly lower than the HFD group(P<0.05),with the most significant decrease in the 40%VO2max group(P<0.05).Moreover,the average renal mito-chondrial SOD and membrane potential levels in the HFD group decreased significantly compared with the CON group(P<0.05),while those in the 40%and the 60%VO2max groups were significantly higher than the HFD group(P<0.05).Conclusion Moderate to low intensity aerobic exercise can relieve renal dysfunction of obese rats by lowering the level of oxidative stress in renal mitochondria,mainly down-regulating such renal function biochemical indicators as SCr,serum cystatin C,and mALB,as well as alleviating the degree of renal tissue damage.

Objective To observe the effect of different exercises on relieving renal dysfunction in-duced by obesity,and explore their regulatory roles in mitochondrial biogenesis and mitophagy in this process.Methods Male Sprague-Dawley rats aged 5 weeks were selected as the experimental subjects.Among them,8 were randomly selected as normal diet quiet control group(NC group),while the rest were on high-fat diet to establish obesity-induced renal dysfunction.After successful modeling,they were randomly divided into a high-fat diet sedentary control group(HC group),an aerobic exercise group(AT group),a resistance training group(RT group),and a combined exercise group(AT+RT group),each of eight.The AT group underwent daily 60-minute aerobic exercise on a treadmill with an intensity of 55％-65％ of the maximum oxygen uptake,5 days/week,the RT group performed pro-gressive load resistance training using a ladder climbing method,3 days/week,8 sets/day,while the AT+RT group underwent aerobic and resistance exercise alternatingly,5 days/week,for 8 weeks suc-cessively.At the end of the intervention,24-hour urine samples were collected to test the microalbu-minuria(MAU),blood samples were taken to measure lipid profile,serum creatinine(SCR),and cys-tatin C(CysC).Moreover,epididymal and perirenal fat were weighed and recorded,and kidney tissues were examined the mitochondrial membrane potential.Meanwhile,hematoxylin and eosin staining was used to observe pathological changes in the kidney,and Western blotting was conducted to detect the protein expression levels of peroxisome proliferator-activated receptor gamma coactivator 1 alpha(PGC-1α),mitochondrial transcription factor A (Tfam),Bcl-2-interacting myosin like coiled-coil protein(Be-clin1),PTEN-induced kinase1 (PINK1),and Parkinson disease kinase(Parkin) in kidney tissues.Re-sults After 8-week exercise,the body weight in the AT,RT,and AT+RT groups was significantly low-er than the HC group(P<0.01).The Lee's index in the AT and RT groups was significantly lower than the HC group(P<0.01,P<0.05),and the adiposity ratio in the RT group was lower than the lat-ter(P<0.01).Moreover,the MAU level in the HC group was significantly higher than the other four groups(P<0.05).In addition,serum triglycerides(TG) and total cholesterol(TC) levels in the AT,RT,and AT+RT groups were significantly lower than the HC group(P<0.01,P<0.05),and the low-density lipoprotein cholesterol(LDL-C) level in the AT group was also significantly lower than the latter group (P<0.05).Meanwhile,SCR levels in the AT,RT,and AT+RT groups were significantly lower than the HC group(P<0.05,P<0.01),with the lowest SCR levels in the RT group and CysC levels in the AT and AT+RT groups significantly lower than the HC group(P<0.05).Besides,the glomerular area of the HC group was significantly larger than all the other groups(P<0.01).(6) The mitochondrial membrane potential of kidney cells was highest in the NC group,followed by the HC group,with that of the AT+RT group significantly lower than the NC group(P<0.01).Compared with the HC group,the expression levels of PGC-1α and Tfam protein were significantly higher in the AT,RT,and AT+RT groups(P<0.01) and that of Beclin1 protein was significantly higher in the AT group(P<0.05),while the expression levels of Parkin protein in the AT and RT groups were significantly high-er than the NC group(P<0.05).Conclusion Aerobic training,resistance training,or a combination of both interventions over 8 weeks can effectively reduce fat and weight,relieving the renal dysfunction in obese rats.Resistance training has a significant effect on delaying weight gain and reducing TG and SCR,while aerobic exercise effectively lowers LDL-C and CysC levels.All forms of exercise can en-hance the expression levels of key proteins associated with mitochondrial biogenesis,with aerobic exer-cise demonstrating a more pronounced intervention effect in upregulating the expression of mitophagy proteins.
