Objective To investigate the effects of simvastatin on the expression of lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) induced by oxidized low-density lipoprotein (ox-LDL) or Glucose in U937 macrophages, and explore the role of NF-κB in modulating of LOX-1 expression. Methods U937 macrophages were treated with PMA to induce differentiation, which were co-cultured with 50 mg/L ox-LDL or/and 25 mmol/L glucose. Pyrrolidine dithiocarbamate (PDTC) and simvastatin (1 μmol/L or 10 μmol/L) were used to treat cells. The expression of LOX-1 protein and NF-κB ac- tivity were detected by enzyme-linked immunosorbent assay technology. The expression of LOX-1 mRNA was measured by RT-PCR. Results The expression of LOX-1 was up regulated by ox-LDL, glucose and combination of both. The inhibitor of NF-κB PDTC suppressed this up-regulation. Simvastatin suppressed the expression of LOX-1 induced by ox-LDL, and showed a significant effect in the higher concentration. There was no significant effect of simvastatin on the expression of LOX-1 induced by glucose. The variation of NF-κB activity was similar to that of LOX-1 expression. Conclusion Simvas- tatin suppressed the expression of LOX-1 induced by ox-LDL, while no significant effect on the expression of LOX-1 in- duced by glucose. The expression and regulation of LOX-1 were related with NF-κB pathway.

Objective To explore the value of sonogram index scoring system in the prenatal diagnosis of trisomy 18 syndrome.Methods Neonates who had prenatal sonographic screening in our tertiary center were followed up from January 2004 to December 2009.The fetuses who were suspected with abnormalities received karyotype analysis.All fetuses were divided into case group ( trisomy 18 group) and the control group (non-trisomy 18 group).The latter group was constituted of fetuses with trisomy 21,trisomy 13,other chromosomal abnormalitis and fetuses with normal karyotype.Logistic regression analysis was done to decide the individual sonographic features of trisomy 18.A score was assigned for ultrasound markers according to their likelihood ratios for trisomy 18 syndrome.A score of 3 was assigned for the sonographic features with likelihood ratio over 200,2 for those with likelihood ratio between 100 and 200,and 1 for those with likelihood ratio less than 100.The diagnostic efficacy of the ultrasound index scoring system was evaluated by diagnostic test.The optimal cutoff value was determined by receiver operating characteristic (ROC) curve.Results The study group included 59 fetuses with trisomy 18.And 26 486 fetuses did not have trisomy 18 syndrome,including 93 fetuses with trismoy 21,19 fetuses with trisomy 13,134 fetuses with other chromosomal abnormalities,3739 fetuses with normal karyotype and 22 501 fetuses with normal appearance after birth.Two or more structural defects were observed in each trisomy 18 fetus.The highest incidence of sonogram abnormalities was extremities abnormalities (85％,50/59 ),followed by cardiac defects (83％,49/59) and central nervous system (CNS) malformations (75％,44/59).Overlapping fingers,ventricular septal defect and strawberry-shaped skull were the most common abnormalities in extremities abnormalities,cardiac defects and CNS malformations,respectively.Logistic regression identified 16 markers,including choroid plexus cyst,strawberry-shaped skull,enlarged cisterua magna,holoprosencephaly,low-set ears,ventricular septal defect,hypoplastic left heart syndrome,etc.Different scores were assigned according to the likelihood ratios of these markers.In trisomy 18 group,fetuses with the sonographic score of 1,4,9,10 to 16 were 2％ ( 1/59),9％ (5/59),10％ (6/59) and 32％ (19/59) respectively,whereas in non-trisomy 18 group they were 2.549％ (675/26 486),0.215％ (57/26 486),0.004％ ( 1/26 486) and zero,respectively.When a score of 4 was used as the cutoff value for diagnosing fetal trisomy 18,the sensitivity and specificity were 0.966 and 0.997,respectively.The area under ROC curve was 0.999.Conclusions The ultrasound index scoring system may help to quantify the ultrasound features and has a good diagnostic value for fetal trisomy 18 syndrome.The cutoff value of 4 has the best diagnostic efficacy.

Objective To explore the differences of macrostructural and microstructural and their correlations in brain white matter (WM) between left-and right-handed adults.Methods Structural magnetic resonance imaging (sMRI) and diffusion tensor imaging (DTI) were performed on twenty-three left-handed (LH) and thirty-two right-handed (RH) healthy subjects.The WM volume,fractional anisotropy (FA) and mean diffusivity (MD) were mearsured and compared between the two groups by using the voxel-based morphometry (VBM) and voxel-based analysis (VBA) methods.Results (1) LH adults showed lower WM volume than RH adults in bilateral splenium of corpus callosum (SC) (Left:x=-15,y=-57,z =13.5,t=-5.160;Right:x=18,y=-42,z=12,t=-3.654;P＜0.001).Compared with the RH adults,the FA values in WM of the left postcentral gyrus (PoCG) (x =-24,y =-46,z =54) and the above left insula (INS) (x =-36,y =-12,z =20) increased (P＜ 0.001),as well as the average FA values,the average length and number of streamlines in WM tracts increased (P＜0.05) in LH adults.Compared with the RH adults,the MD values in the right HIP (x=24,y=-34,z=-2) decreased(P＜0.001),as well as the average MD values decreased,and the average length in WM tracts increased (P＜0.05) in LH adults.(2)There was positive correlation between FA and the volume of right splenium of corpus callosum in LH and RH adults (LH:r=0.716,RH:r=0.471,P＜0.05).There was negative correlation between FA and MD in the left PoCG (LH:r=-0.769,RH:r=-0.841),left INS (LH:r=-0.775,RH:r=-0.744) and right HIP (LH:r=-0.842,RH:r=-0.742) in LH and RH adults (all P＜0.05).Conclusion There are differences in both macrostructure and microstructure of white matter in several brain regions and WM tracts between left-handed and right-handed people,and correlations between these measures were also observed.

Objectives:To investigate the predictive effect of regional homogeneity (ReHo) from resting-state functional magnetic resonance imaging (rs-fMRI) in acute phase on memory function of chronic phage in ischemic stroke patients and the effects of residual learning (REL) on the predictive performance of machine learning models.Methods:From June 2019 to June 2021, rs-fMRI data of one-week after stroke (acute phase) were collected from 35 first-time ischemic stroke patients, and their memory scores were assessed by the Rey auditory verbal learning test (RAVLT) at 6 months after stroke (chronic phase). Using ReHo from rs-fMRI data in acute phase of ischemic stroke patients, the support vector regression (SVR) and the REL-based SVR (REL-SVR) were constructed to predict the patients’ memory scores at 6 months after stroke, and the performance of the two models was compared using Pearson correlation coefficient.Results:Based on the ReHo from acute phase, the correlation coefficient between the predicted values and the true scores from the SVR model was r=0.524, P=0.001, while the correlation coefficient obtained by the REL-SVR model was r=0.671, P<0.001. Brain regions with relatively higher weights such as Temporal_Pole_Mid_R (weight value: 1.03), Temporal_Mid_R(weight value: 1.03), Temporal_Inf_R (weight value: 1.03), Occipital_Mid_R (weight value: 0.57), Frontal_Mid_L (weight value: 0.32), Frontal_Sup_Medial_L (weight value: 0.53), SupraMarginal_L (weight value: 1.54), Calcarine_L (weight value: 0.65), Lingual_L (weight value: 0.58), Cuneus_L (weight value: 0.65), Precuneus_L (weight value: 0.83), cerebellum(weight value>1.0) made larger contributions to the prediction model. Conclusions:ReHo in the acute-phase can effectively predict memory in the chronic phase of ischemic stroke patients. Furthermore, REL can improve the performance of the traditional SVR model and achieve higher predictive accuracy.

Objective: To investigate the clinical features and change trend of patients with acute coronary syndrome(ACS) undergoing emergent percutaneous coronary intervention(PCI). Methods: In this retrospective study, we retrieved all medical records of 4 907 ACS patients who underwent emergent PCI in Fuwai hospital from January 1,2010 to December 31,2016. We analyzed the clinical features and change trend in these patients. According to clinical diagnosis, patients were grouped as ST-elevated myocardial infarction(STEMI) group (3 719 cases) and NSTE-ACS group (patients with non-STEMI and unstable angina, 1 188 cases). Results: The ACS patients were aged (59.5±11.8) years old. There were 3 772 males and 1 135 females. The annual number of ACS patients underwent emergent PCI increased from 412 patients in 2010 to 1 067 patients in 2016. The number of NSTE-ACS patients increased from 11.4% (47/412) in 2010 to 26.5% (283/1 067) in 2016. Compared with STEMI group, patients in NSTE-ACS group were significantly older ((61.2±10.9) years old vs. (58.9±12.1) years old,P<0.01).The percent of female patients (30.1% (358/1 188) vs. 20.9% (777/3 719), P < 0.01), history of hypertension (69.1% (821/1 188) vs. 60.4% (2 248/3 719,P <0.01), previous PCI (25.8% (307/1 188) vs. 12.4% (461/3 719), P <0.01), and previous coronary artery bypass grafting (3.0% (36/1 188) vs. 1.0% (37/3 719), P <0.01) were all significantly higher in NSTE-ACS group than in STEMI group. On the other hand, NSTE-ACS patients presented less chronic renal failure (2.9% (35/1 188) vs. 4.3% (173/3 719), P <0.05) and hepatic dysfunction (8.5% (101/1 188) vs. 13.3% (495/3 719), P<0.01) as compared to ACS patients. In coronary angiography, NSTE-ACS patients had a higher prevalence of left-main disease (14.0% (166/1 188) vs. 7.8% (291/3 719), P<0.012 5) and triple vessel disease (47.8% (568/1 188) vs. 43.5% (1 619/3 719), P<0.012 5). There were no differences in prevalence of diabetes mellitus (31.9% (1 187/3 719) vs. 34.8% (414/1 188),P>0.05) and acute renal failure (0.1% (38/3 719) vs. 0.6% (7/1 188),P>0.05) between STEMI group and NSTE-ACS group. Conclusions This single center retrospective analysis reveals that there is an increasing trend of NSTE-ACS patients from 2010 to 2016. Furthermore, there are more high-risk clinical characteristics in NSTE-ACS patients than in STEMI patients.

Introduction::Observational studies have revealed an association between waist circumference (WC) and atrial fibrillation (AF). However, it is difficult to infer a causal relationship from observational studies because the observed associations could be confounded by unknown risk factors. Therefore, the causal role of WC in AF is unclear. This study was designed to investigate the causal association between WC and AF using a two-sample Mendelian randomization (MR) analysis.Methods::In our two-sample MR analysis, the genetic variation used as an instrumental variable for MR was acquired from a genome-wide association study (GWAS) of WC (42 single nucleotide polymorphisms with a genetic significance of P <5 × 10 –8). The data of WC (from the Genetic Investigation of ANthropometric Traits consortium, containing 232,101 participants) and the data of AF (from the European Bioinformatics Institute database, containing 55,114 AF cases and 482,295 controls) were used to assess the causal role of WC on AF. Three different approaches (inverse variance weighted [IVW], MR–Egger, and weighted median regression) were used to ensure that our results more reliable. Results::All three MR analyses provided evidence of a positive causal association between high WC and AF. High WC was suggested to increase the risk of AF based on the IVW method (odds ratio [OR] = 1.43, 95% confidence interval [CI], 1.30–1.58, P = 2.51 × 10 -13). The results of MR–Egger and weighted median regression exhibited similar trends (MR–Egger OR = 1.40 [95% CI, 1.08–1.81], P = 1.61 × 10 -2; weighted median OR = 1.39 [95% CI, 1.21–1.61], P = 1.62 × 10 -6). MR–Egger intercepts and funnel plots showed no directional pleiotropic effects between high WC and AF. Conclusions::Our findings suggest that greater WC is associated with an increased risk of AF. Taking measures to reduce WC may help prevent the occurrence of AF.

The sufficiency of hard and soft tissue at the implant site is the guarantee of long-term function, health and the appearance of implant denture. Problem of soft tissue recession at the implant site has always been bothering dentists. Traditional methods for augmentation of soft tissue such as gingival transplantation have disadvantages of instability of the increased soft-tissue and more trauma. Lately the methods that base on tissue engineering to increase the soft tissue of peri-implant sites have drawn great attention. This review focuses on the current methods of peri-implant restoration through tissue engineering, seed cells, biological scaffolds and cytokines.

A systematic characterization of the similarities and differences among different methods for detecting structural brain abnormalities in schizophrenia, such as voxel-based morphometry (VBM), tensor-based morphometry (TBM), and projection-based thickness (PBT), is important for understanding the brain pathology in schizophrenia and for developing effective biomarkers for a diagnosis of schizophrenia. However, such studies are still lacking. Here, we performed VBM, TBM, and PBT analyses on T1-weighted brain MR images acquired from 116 patients with schizophrenia and 116 healthy controls. We found that, although all methods detected wide-spread structural changes, different methods captured different information - only 10.35% of the grey matter changes in cortex were detected by all three methods, and VBM only detected 11.36% of the white matter changes detected by TBM. Further, pattern classification between patients and controls revealed that combining different measures improved the classification accuracy (81.9%), indicating that fusion of different structural measures serves as a better neuroimaging marker for the objective diagnosis of schizophrenia.
