Objective To investigate the effects of force on mechanical stability of FLNa-Ig21/αⅡbβ3-CT complex and the regulation mechanism.Methods The FLNa-Ig21/αⅡbβ3-CT crystal structures were taken from the PDB database.The stability of the complexes in a physiological environment as well as the unfolding path and mechanical stability induced by mechanical forces were analyzed using equilibrium and steered molecular dynamics simulations.Results During the equilibration,the survival rate of most salt bridge and hydrogen bonds was below 0.5,and the interactions between FLNa-Ig21 and αⅡbβ3-CT was relatively weak.During stretching at a constant velocity,the complex could withstand a tensile force of 70-380 pN,and its mechanical strength depended on the force-induced dissociation path.Under a constant force of 0-60 pN,the complexes exhibited a slipping-bond trend,and the force increase facilitated the breakage of the R995-D723 salt bridge and the activation of αⅡbβ3 integrin.Conclusions The force-induced allostery of αⅡbβ3-MP enhanced the complex mechanical strength and delayed FLNa-Ig21 dissociation from αⅡbβ3-CT.After breaking through the 20 pN threshold,force positively regulated the activation of αⅡbβ3 integrin.These results provide insights into the molecular mechanism of αⅡbβ3 activation and the development of related targeted drugs.

Objective To analyze the characteristics of time in range(TIR)and its relationship with oxidative stress(OS)and insulin resistance status(HOMA-IR)in patients with type 2 diabetes mellitus(T2DM)and sleep apnea-hypopnea syndrome(OSAHS).Methods According to apnea-hypopnea index(AHI),165 T2DM in patients were divided into simple T2DM group(AHI<5 times/h,n=43),T2DM combine OSAHS mild group(OSAHS-G,5≤AHI<15 times/h,n=51),T2DM combined OSAHS moderate group(OSAHS-M,15≤AHI≤30 times/h,n=40)and T2DM combine OSAHS severe group(OSAHS-S,AHI>30 times/h,n=31).TIR was calculated by dynamic blood glucose monitoring.Superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and other indexes were detected and analyzed.Results Compared with simple T2DM group,the levels of HOMA-IR,8-iso-PGF2a and Ox-LDL were higher in T2DM combined OSAHS-G,OSAHS-M or OSAHS-S group,while the levels of TIR,SOD and GSH-Px were lower(P<0.05).Pearson correlation analysis showed that TIR was positively correlated with the levels of SOD and GSH-Px(P<0.05 or P<0.01),and negatively correlated with the levels of 8-iso-PGF2a,Ox-LDL,HbA1c,HOMA-IR and the severity of OSAHS(P<0.01).Logistic regression analysis showed that TIR,SOD and GSH-Px were protective factors for severe OSAHS in T2DM patients,while 8-iso-PGE2a and Ox-LDL were the risk factors for severe OSAHS.Conclusions The glucose level fluctuates greatly in patients with T2DM and OSAHS.Insulin resistance and oxidative stress are factors that affect the normalization of TIR.

Patients with bicuspid aortic valve (BAV) are characterized by asymmetric anatomy, severe calcification and combined aortic dilatation. Compared with tricuspid aortic valve stenosis patients, patients with BAV stenosis confront with greater surgical risks in transcatheter aortic valve replacement (TAVR), including paravalvular leak, aortic valve rupture, coronary artery obstruction, atrioventricular block and so on. However, with the advent of new generation of prosthetic valves and optimization of surgical strategies, several studies have shown that TAVR is safe and effective in the treatment of BAV stenosis. Therefore, we aim to provide an overview of the use of TAVR in patients with BAV stenosis.

Objective:To explore the expression of peptidyl prolyl cis-trans isomerase (Pin1) activity in peripheral blood of patients with rheumatoid arthritis (RA) and the value and correlation of T helper cell 17/regulatory cells (Th17/Treg) cells, and to analyze the effect and influence of all-transretinoic acid (ATRA) on it.Methods:① Comparing the difference of Pin1 expression and absolute counts of Th17 and Treg between RA patients before and after treatment and healthy control group, Kruskal-Wallis rank sum test was used for analysis. ② To analyze the correlation between the expression of Pin1 and its general data, activity indicators [such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score 28 joints (DAS28) scores], Th17, Treg and some cytokines in RA patients, and to use Pearson and Spearman correlation tests. ③ To analyze the difference of Pin1 expression and Th17/Treg in peripheral blood of RA patients treated with low-dose all-trans retinoic acid (10 mg twice a week) and traditional immunosuppressants such as hydroxychloroquine for 3 months respectively. Mann-Whitney U test was used for comparison between the two groups, and the difference was statistically significant with ( P<0.05). Results:① The activity of Pin1 in peripheral blood of the newly treated group of RA was [13.62(9.16, 19.42)] higher than that of the healthy control group [8.97(7.62, 11.45)]( Z=42.82 , P<0.05), and Th17 was [18.28(12.76, 24.08)] higher than that of the healthy control group [6.04(4.96, 4.96)]( Z=48.83 , P<0.05). Treg [11.06(5.31, 21.87). It was lower than that of healthy control group [40.41(24.33, 48.52)]( Z=42.21 , P<0.05). ② the activity of Pin1 in peripheral blood of RA patients was positively correlated with CRP, the number of involved joints, DAS28 score, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) ( r=0.396, P<0.05; r=0.683, P<0.05; r=0.466, P<0.05; r=0.315, P<0.05; r=0.416, P<0.05). ③ Compared with the newly treated RA group, the activity of Pin1 [6.94(5.96, 8.77), Z=42.82 , P<0.05] and Th17 7.38 decreased [7.38(3.85, 11.21), Z=48.83 , P<0.05], while Treg [40.41 (17.77, 33.47)] increased ( Z=42.21 , P<0.05). ④ Compared with the traditional medicine group, Treg [28.9(21.73, 37.36)] was higher in the retinoic acid group, and the difference was statistically significant ( Z=-2.683 , P<0.05). The activity of Pin1 was [6.23(5.58, 8.75)], but there was no statistical significance ( Z=-1.622 , P=0.104). Conclusion:Pin1 in peripheral blood of RA patients is over-expressed. Th17 is increased and Treg is decreased. ATRA combined with other traditional drugs can reduce Pin1 activity, promote Treg growth and improve disease activity of RApatients to a certain extent.

Objective:To evaluate the effects of supra-arch branches bypass on cerebral oxygen saturation and hemodynamics in patients with Stanford type B aortic dissection.Methods:From January to December 2018, consecutive 27 patients with Stanford type B aortic dissection were enrolled in the study. All patients received hybrid treatment, including supra-arch branches bypass(right axillary artery-left common carotid artery-left subclavian artery) and thoracic endovascular aortic repaire(TEVAR). All the operations were performed by the same surgical team. The left and right cerebral oxygen saturation were measured after anesthesia(T1), left carotid artery occlusion(T2) and after operation(T3); peak systolic velocity(PSV) and resistance index(RI) of left and right carotid arteries were measured before(t1) and after operation(t2).Results:The left cerebral oxygen saturation was 0.62 ±0.01, 0.54±0.01 and 0.62±0.01 at T1, T2 and T3, respectively. There was significant difference between T2 and T1 and T3( P=0.002, P=0.001), but there was no significant difference between T1 and T3. The PSV of left carotid artery at t1 and t2 were(0.91±0.11)m/s and(0.76±0.09)m/s respectively, with no significant difference( P= 0.191). The RI of left carotid artery at t1 and t2 were 0.83±0.06 and 0.93±0.13 respectively, with no significant difference( P= 0.575). Conclusion:If one side of carotid artery was blocked for a short time during supra-arch branches bypass, the cerebral oxygen saturation would be decreased temporarily, but the changes of cerebral oxygen metabolism could be completely restored after operation. However, the hemodynamics of carotid artery would not change significantly. In the hybrid treatment strategy for the patients with aortic dissection Stanford type B, blocking bilateral carotid arteries can be avoided. Making the right axillary artery-left common carotid artery-left subclavian artery shunt is a safe and effective choice.

Objective: To assess the accuracy and application value of type III portable monitor (III PM) of sleep apnea (SA) for in-hospital patients with cardiovascular disease (CVD). Methods: A total of 101 CVD patients received sleep apnea monitoring by both type II polysomnography ( II PSG) and III PM were enrolled to compare the apnea-hypopnea index (AHI) measured by 2 instruments. AHI was assigned into 4 grades: Normal (AHI<5), Mild grade (5≤AHI<15), Moderate grade (15≤AHI<30) and Severe grade (AHI≥30). Kendall correlation coefficient and Kappa value were calculated, pair wise t test was conducted in relevant patients. Results: II PSG and III PM measured AHI were (18.0±16.6) events/h and (18.6±17.4) events/h, P>0.05. Kendall correlation coefficient for 4 AHI grades was 0.701, P<0.01 which assumed strong correlation; Kappa value of consistency was 0.493, P<0.01 which assumed medium strong correlation. Using AHI≥15 as cut-off point, Kappa coefficient for the consistency between II PSG and III PM was 0.679, P<0.05, which meant high consistency. Taking II PSG as standard and AHI≥15 as cut-off point, the AUC of III PM measured AHI was 0.918 with the specificity at 80.4% and sensitivity at 87.3%. The best diagnosing cut-off value of III PM was AHI=15.70, at this point, the maximum Youden's index was obtained as 0.695. Conclusion: Using AHI≥15 as standard, III PM and II PSG had the favorable consistency and accuracy for monitoring the severity of SA for in-hospital patients with cardiovascular disease. AHI=15.7 was the best cut-off point of III PM in diagnosing moderate and severe SA in relevant patients.
