Objective The aim of this study was to screen and verify the proteins interacting with Vimentin,investigate the regulatory relationship between FABP5 and candidate proteins,and further explore the mechanism of FABP5 in hepatocellular carcinoma.Methods Immunoprecipitation combined with tandem mass spectrometry(IP-MS)was used to screen the proteins that bind to FABP5.The binding relationship between FABP5 and candi-date interacting proteins was verified from the exogenous and endogenous levels by Co-immune precipitation assay(Co-IP).RT-qPCR,Western blot and immunofluorescence were used to observe the effect of knockdown FABP5 on the transcription and translation of Vimentin in HCC cells.The effect of overexpressing FABP5 on the cytoskeleton of HCC cell was observed by phalloidin staining.Results 336 potential target proteins that bind to FABP5 were identi-fied through IP-MS.Based on literature,five candidate proteins related to tumors were selected,namely PRDX1,PRSS3,PKM,HSP90AA1,and Vimentin.The binding relationship between FABP5 and Vimentin protein was con-firmed through both exogenous and endogenous Co-IP.Knockdown FABP5 has no significant effect on the expression of Vimentin mRNA,but it can inhibit the expression of Vimentin protein,and overexpression of FABP5 can affect the cytoskeleton of HCC cell.Conclusions FABP5 promotes the migration and invasion of HCC cells by the regula-tion of Vimentin and the influence of cytoskeletal remodeling,and thus it is expected to be a potential target for anti-HCC and provide new ideas for the treatment of HCC.

Objective To investigate the changes in interleukin-34 (IL-34)levels in serum and bronchoalveolar lavage fluid (BALF) of patients with severe pneumonia and their prognostic value. Methods A total of 66 patients with severe pneumonia (severe pneumonia group), 35 patients with non-severe pneumonia (non-severe pneumonia group), and 27 healthy adults (control group) were enrolled. The severe pneumonia group was further divided into survival group of 38 patients and non-survival group of 28 patients based on 28-day survival. Clinical data of all subjects were analyzed. Receiver operating characteristic (ROC) curves were plotted to assess the predictive power of serum IL-34 and relative IL-34 gene expression in BALF for 28-day mortality in patients with severe pneumonia, as well as the predictive power of serum IL-34 for severe pneumonia. Kaplan-Meier survival curves were plotted, and the Log-rank test was used to compare cumulative survival rates. Cox regression analysis was conducted to explore risk factors for 28-day mortality in patients with severe pneumonia. Pearson correlation analysis was used to assess the correlation between serum IL-34 levels and relative IL-34 gene expression in BALF of patients with severe pneumonia. Results Serum IL-34 levels were higher in the severe pneumonia group than those in the non-severe pneumonia group, and were higher in the non-severe pneumonia group than in the control group (P < 0.05). Serum IL-34 levels and relative IL-34 gene expression in BALF were higher in the non-survival group than in the survival group (P < 0.05). ROC curve analysis showed that the areas under the curve for predicting 28-day mortality in patients with severe pneumonia were 0.908 for serum IL-34 levels and 0.878 for relative IL-34 gene expression in BALF. The optimal cutoff value for serum IL-34 levels in predicting severe pneumonia was 129.9 pg/mL. Multivariate Cox regression analysis showed that increased serum IL-34 levels and increased relative IL-34 gene expression in BALF were independent risk factors for 28-day mortality in patients with severe pneumonia (P < 0.05). The Kaplan-Meier survival analysis results indicate that, with a cutoff value of 129.9 pg/mL, patients with severe pneumonia who had high serum levels of IL-34 exhibited a lower cumulative survival rate compared to those with low IL-34 level(Log-rank P < 0.001). Conclusion Serum IL-34 levels are significantly increased in patients with severe pneumonia, and relative IL-34 gene expression in BALF is positively correlated with serum IL-34 levels. Both can be used as indicators for predicting the prognosis of 28-day mortality in patients with severe pneumonia.

Objective To investigate the application of artificial intelligence-based follow-up plan for patients after percutaneous coronary intervention(PCI).Methods The follow-up plan of artificial intelligence after PCI was constructed through literature review and expert correspondence consultation.A total of 82 patients with coronary heart disease who underwent PCI in the Second Affiliated Hospital of Nanchang University from October 2022 to November 2023 were selected and divided into intervention group and control group according to random number table method,with 41 cases in each group.The control group was given routine nursing program,and the intervention group was added artificial intelligence-based follow-up program on the basis of control group.The incidence of major adverse cardiovascular event(MACE)within 6 months,30 days readmission rate,medication compliance and satisfaction score were compared between two groups.Results The incidence of MACE within 6 months and 30 days readmission rate in intervention group were significantly lower than those in control group(P＜0.05).After 6 months of intervention,Morisky scale score and satisfaction score of patients in two groups were significantly higher than before intervention(P＜0.05),and Morisky scale score and satisfaction score of patients in intervention group were significantly higher than those in control group(P＜0.05).Conclusion Follow-up program based on artificial intelligence technology can reduce the incidence of MACE and 30 days readmission rate of patients after PCI.

During PVC-V the rotation and twist degree is further reduced ,and the time sequence altered , accompanied with significantly decreased LVEF .

Objective To explore the effect of propagating and educating (planning, doing, checking, and acting) circulation combined with neuronavigation system on improving surgical coordination at perioperative nursing in patients with pituitary tumors. Methods One hundred and sixteen patients with pituitary tumors, admitted to and accepted neuronavigation assisted microsurgery in our hospitals from August 2016 to August 2018, were chosen in our study; these patients were randomly divided into experimental group and control group (n=58). Patients from the control group accepted traditional perioperative propagating and educating circulation, while patients from the experimental group accepted perioperative propagating and educating (planning, doing, checking, and acting [PDCA]) circulation. Awareness rate of surgical preparation knowledge, self-rating anxiety scale (SAS) scores, degrees of operation coordination, length of hospital stays, hospitalization cost and postoperative complications were compared between the two groups. Results As compared with patients in the control group, patients in the experimental group had significantly higher knowledge of surgical preparation, statistically lower SAS scores and statistically lower proportion of patients with poor surgical coordination (P<0.05). As compared with those in the control group, the hospitalization cost, length of hospital stays and incidence of surgical complications (5.1％ vs. 12.1％) in the experimental group were statistically decreased (P<0.05). Conclusions PDCA circulation combined with neuronavigation system can be used as a kind of brand-new education mode for patients with pituitary adenomas. As compared with traditional perioperative mode, the new mode can significantly improve the awareness rate of surgical preparation knowledge, relieve anxiety level, improve cooperation degree, and reduce the postoperative complications, length of hospital stays, and hospital expenses, which means great clinical significance.

Objective To investigate the left ventricular (LV) torsion parameters of type B WolffParkinson-White syndrome (B-WPW) and to explore alternation of the left ventricular motion pattern in patients with B-WPW.Methods Thirty-eight patients with B-WPW were studied.And 40 volunteers were selected as control.Two-dimensional speckle tracking imaging (2D-STI) was used to acquire left ventricular torsion parameters,including peak value and time to peak value of LV twist,LV apex rotation,and LV base rotation.Apical-basal rotation delay (RDA-B) was calculated.Biplane Simpson method was used to measure LV end-diastolic volume (LVEDV),end-systolic volume (LVESV) and ejection fraction (LVEF).All above parameters were measured in patients with B-WPW before (B-WPW-B group) and after (B-WPW-A group) radiofrequency catheter ablation and in control group.The QRS width of lead Ⅱ was recorded,and the relationships between all above parameters with the RDA-B or QRS width were analyzed.Results Compared with the contrd group,in patients with B-WPW,the peak value of LV apex rotation (RotA),LV base rotation (RotB) and LV twist (TwistLV) were lower(LV base was more obvious than LV apex)(P ＜0.05),the time to RotB (TTPB) was shorter (P =0.004),RDAB was longer(P =0.002),the left ventricular enlarged and the QRS prolonged (P =0.000).After radiofrequency catheter ablation,the left ventricular torsion parameters in patients with B-WPW recovered significantly(P ＜0.05),but still lower than those in the control group(P ＜0.05).Conclusions The left ventricular motion pattern of patients with B-WPW alters,including the changes of peak value and time to peak value in LV apex rotation,LV base rotation and LV twist,as well as LV myocardium dyssynchrony.The motion pattern of LV in patients with B-WPW is improved in acute stage after radiofrequency catheter ablation but not yet recover totally.

Objective To explore the association of NH2-terminal pro-B-type natriuretic peptide ( NT-proBNP) with the risk of type 2 diabetes.Methods One hundred and twenty-six impaired glucose regulation( IGR) participants from Diabetic Identification Center of Tianjin Metabolic Diseases Hospital were included.NT-proBNP was measured in plasma samples collected from participants at baseline condition.Results At baseline, NT-proBNP was inversely associated with body mass index, waist circumference, fasting glucose, insulin and low-density lipoprotein-cholesterol( LDL-C) levels.During a follow-up of 2 years, 51 participants reported a new diagnosis of diabetes from OGTT.Baseline quartiles of NT-proBNP were inversely associated with diabetes risk, even after multivariable adjustment.Theadjustedrelativerisksfordiabeteswere1.0(reference),0.83(95%CI0.74-0.96),0.78(95%CI 0.68-0.90), 0.74 (95%CI 0.64-0.87) for the 1st, 2nd, 3rd, and 4th quartiles of baseline NT-proBNP, respectively ( P<0.01 ) .Conclus ion In IGRpopulation , lowlevels of NT-proBNP were associated with a significantly increased risk of type 2 diabetes.

Objective To compare the left ventricular function parameters of patients with sick sinus syndrome ( SSS ) and DDD pacemaker implantation during atrioventricular conduction ( AVC ) and right ventricular apex pacing ( RVAP ) mode . Methods Forty‐six consecutive patients with SSS who had undergone DDD pacemaker implantation were studied . Fifty volunteers were included as control group . Changing from AVC to RVAP mode ,the acute effect on echocardiographic parameters ,including LVEF , parameters of aortic/pulmonary artery pulse wave Doppler ,and parameters of left ventricular twist by speckle tracking imaging were measured respectively . Pacemaker implantation duration and cumulative ventricular pacing proportion ( Cum% VP) were recorded . The relationships of pacemaker parameter and above left ventricular function parameters were analyzed . Results Compared with control group ,values of peak rotation in LV apex and LV twist were significantly lower during AVC and RVAP mode . The value of peak rotation in LV base showed no significant difference between three groups .Apical‐basal rotation delay during RVAP was significantly longer than those during AVC and in control group respectively ( P <0 .05) . LVEF during RVAP decreased statistically ( P< 0 .05 ) ,but showed no difference during AVC , compared with the control group . The peak LV twist related positively with LVEF ,and negatively with Cum% VP . Conclusions RVA pacing decreases left ventricular function , which is independent of asynchrony contraction patterns caused by pacing . LVEF ,apical rotation and LV twist are more sensitive to demonstrate the LV dysfunction in patients with pacemaker implantation . LV twist related negatively with Cum% VP .
