Objective:Type H blood vessels are a subtype of bone-specific microvessels(CD31hiEmcnhi)that play an important regulatory role in the coupling of angiogenesis and osteogenesis.Despite reports on the distinct roles of type H and L vessels under physiological and pathological bone conditions,their genetic differences remain to be elucidated.This study aims to construct a competitive endogenous RNA(ceRNA)network of key gene for differencial expression(DE)in type H and L vascular endothelial cells(ECs)through integrated bioinformatic methods. Methods:We downloaded relevant raw data from the ArrayExpress and the Gene Expression Omnibus(GEO)database and used the Limma R-Bioconductor package to screen for DE lncRNAs,DE miRNAs,and DE mRNAs between type H and L vascular ECs.A total ceRNA network was constructed based on their interactions,followed by refinement using protein-protein interaction(PPI)networks to select upregulated and downregulated key genes.Enrichment analysis was performed on these key genes.Random validation was conducted using flow cytometry and real-time RT-PCR. Results:A total of 1 761 DE mRNAs,187 DE lncRNAs,and 159 DE miRNAs were identified,and a comprehensive ceRNA network was constructed based on their interactions.Six upregulated(Itga5,Kdr,Tjp1,Pecam1,Cdh5,and Ptk2)and 2 downregulated(Csf1r and Il10)key genes were selected via PPI network to construct a subnetwork of ceRNAs related to these key genes.Upregulated key genes were mainly enriched in negative regulation of angiogenesis and vascular apoptosis.Results from flow cytometry and real-time RT-PCR were consistent with bioinformatics analysis. Conclusion:This study proposes a ceRNA network associated with upregulated and downregulated type H and L vascular ECs based on selected key genes,providing new insights into the regulatory mechanisms of type H and L vascular ECs in bone metabolism.

Objective:To compare the clinical efficacy of robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Medical Journal Full-text Database, PubMed, Web of Science and ScienceDirect were searched for literature on robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures. The search time was from the establishment of each database to March 2023. Meta-analysis was performed on the included literature. The random-effects model was used when the heterogeneity between groups was large, and the fixed-effects model was used when the heterogeneity between groups was small.Results:A total of 15 studies were included in the meta-analysis, including 465 patients in the robot-assisted group and 396 patients in the fluoroscopy-assisted group. Meta-analysis showed that the number of fluoroscopies [ SMD=-3.12, 95% CI (-4.34, -1.89), P<0.001], the number of guide pin adjustments [ SMD=-3.75, 95% CI (-6.77, -0.72), P=0.015], intraoperative blood loss [ SMD=-0.83, 95% CI (-1.18, -0.49), P<0.001], and operative time [ SMD=-2.59, 95% CI (-4.11, -1.08), P<0.001] were smaller than those in the fluoroscopy-assisted group. The rate of excellent screw implantation [ OR=10.13, 95% CI (3.67,27.98), P<0.001] of the robot-assisted was larger than the fluoroscopy-assisted group. There was no significant difference in Majeed functional score [ SMD=0.28, 95% CI (-0.0003, 0.55), P=0.050] and fracture healing time [ SMD=-0.14, 95% CI (-0.46, 0.17), P=0.367] between the two groups. Conclusion:Robot-assisted percutaneous sacroiliac screw fixation for posterior pelvic ring fractures has the advantages of less fluoroscopy, less guide pin adjustment, less intraoperative blood loss, shorter operation time, and higher rate of excellent screw position. However, there is no difference in Majeed score and fracture healing time between robot-assisted percutaneous sacroiliac screw fixation and fluoroscopy-assisted percutaneous sacroiliac screw fixation.

Objective To retrospectively analyze the effects of nerve block anesthesia versus general anesthesia on intertrochanteric fracture in the elderly. Methods The 104 elderly inpatients undergoing closed reduction and intramedullary nailing for the treatment of femoral intertrochanteric fractures were recruited into this study at Department of Orthopedics ,Xiangya Hospital ,Central South University from January 2015 to June 2017.Medical records were collected and analyzed by SPSS 16.0 or GraphPad Prism 6.0 software. Results A total of 104 patients were divided into general anesthesia group(n= 48 )and nerve block anesthesia group (n= 56 ). There was no statistical difference in the demographic characteristics between the two groups. The changes in heart rate ,maximum changes of systolic/diastolic blood pressures ,and infusion volume during surgery were lower in the nerve block anesthesia group than in the general anesthesia group [(12.7 ± 7.3)vs. (18.1 ± 7.8)beats/min ,(22.5 ± 8.8/12.2 ± 7.5)mmHg vs. (34.3 ± 7.9/21.6 ± 6.6)mmHg ,(792.9 ± 387.0)ml vs. (1 083.0 ± 445.5)ml ,respectively ,t=3.64 ,7.14 ,6.73 ,5.16 ,all P＜0.01]. There was no statistically significant difference between two groups in other perioperative data and the number of deaths at three months and one year after surgery. Conclusions As compared with the general anesthesia ,the nerve block anesthesia has less effects on the heart rate ,less maximum changes of systolic and diastolic blood pressures ,and less infusion volume during surgery ,and has no significant increase in postoperative mortality ,which is safe and worthy of further promotion.

OBJECTIVE: To assess the association between myeloperoxidase (MPO) gene polymorphism and coronary artery disease (CAD). METHODS: Several databases were used to retrieve relevant literature up to March 2013 by keywords. A Meta-analysis was performed by Stata12.0 software to estimate the pooled odds ratio (OR) and the 95% confidence interval (CI). Heterogeneity among studies was tested and sensitivity analysis was applied. Publication bias was examined using Begg's funnel plot and Egger's linear regression test. RESULTS: A total of 17 studies were included in this Meta-analysis. For MPO -463 G/A polymorphism, the pooled OR of A allele vs G allele was 0.58 [95% CI (0.47-0.72)] and the pooled OR of genotypes AA+AG vs GG was 0.58 [95% CI (0.46-0.72)]. In subgroup analysis of study population, AA and AG genotypes were significantly associated with CAD in Asians but not in Europeans. The MPO -463 G/A polymorphism in the stable angina pectoris subgroup was evaluated in 3 studies and the pooled OR of A allele vs G allele and genotypes AA+AG vs GG for proven CAD was 0.45 [95% CI (0.15-1.37)] and 0.57 [95% CI (0.19- 1.65)]. For MPO -129 A/G gene polymorphism, the pooled OR of genotype GG vs AA+AG was 0.91 [95% CI (0.74-1.10)]. CONCLUSION A allele of MPO -463 G/A gene is associated with decreased risk of CAD except in the Europeans. There is no association between MPO -129 A/G gene polymorphisms and CAD risk.

Objective A link between homocysteine (Hcy) and left ventricular ejection fraction(LVEF) emerged from re-cent studies but was yet not explored specifically in type 2 diabetic patients. This study aimed to assess the relationship between LVEF and Hcy in type 2 diabetic patients. Methods A total of 72 type 2 diabetic patients were selected for this study and were divided into two groups (40 examples with coronary heart disease, 32 examples without coronary heart disease) javascript:Serum Hcy,glycosylated hemoglobin,cholesterol(TC) and triglyceride(TG) were analyzed.LVEF was assessed by echocardiography. Results There was no difference in systolic blood pressure, diastolic blood pressure, glycosylated hemoglobin,total cholesterol and triglyceride in two groups of patients (P>0.05);The serum Hcy was obvi-ously higher in type 2 diabetic patients with coronary heart disease compared to those without (P<0.05);Factors signifi-cantly associated with a LVEF<55%were serum Hcy OR=1.211(95%CI 1.041~1.408) in type 2 diabetic patients with coronary heart disease.The serum Hcy had significant negatively correlation with LVEF (r=-0.706,P=0.000) in type 2 diabetic patients with coronary heart disease. Conclusion This study highlights an inverse relationship between Hcy and LVEF in type 2 diabetic patients with coronary artery disease.The serum Hcy is a risk factor associated with a LVEF<55%.
