Analysis of anesthetic effect of dexmedetomidine in femoral shaft fracture surgery.

To investigate the effect of dexmedetomidine (DEX) on hemodynamics and recovery period after femoral shaft fracture surgery. Fifty-two patients, aged 3 to 7 years, who underwent femoral shaft fracture reduction surgery in our hospital in 2019 were randomly divided into the experimental group (n = 26) and the control group (n = 26). Both groups were given routine propofol combined with remifentanil by intravenous anesthesia.

Clinical implications of plasma Nogo-A levels in patients with coronary heart disease.

Introduction: Nogo-A is an important neurite growth-regulatory protein in the adult and developing nervous system. Recently, increasing evidence has shown that Nogo-A plays important roles in cardiac development and may act as a potential indicator for heart failure. In addition, increased oxidative stress has been found in individuals with cardiovascular diseases.

[Comparison of ultrasound and nerve stimulation techniques for brachial plexus block for regional hemodynamic changes of upper extremity].

Objective: To compare ultrasound guidance versus nerve stimulator guidance supraclavicular brachial plexus block for regional hemodynamic changes of upper extremity.

Methods: Sixty ASA I-II patients scheduled for upper extremity operation were randomly assigned to receive a supraclavicular brachial plexus block guided by either ultrasound (U group, n = 30) or nerve stimulation (N group, n = 30).20 ml mixture of equal volumes of 2% lidocaine and 0.

Influence of granulocyte colony-stimulating factor on cardiac function in patients with acute myocardial infarction and leukopenia after revascularization.

Background: Granulocyte colony-stimulating factor (G-CSF) seems to improve cardiac function and perfusion when used systemically through mobilization of stem cells into peripheral blood, but results of previous clinical trials remain controversial. This study was designed to investigate safety and efficacy of subcutaneous injection of G-CSF on left ventricular function in patients with impaired left ventricular function after ST-segment elevation myocardial infarction (STEMI).

Methods: Thirty-three patients (22 men; age, (68.

[Changes of serum hepatocyte growth factor before and after percutaneous coronary intervention in patients with unstable angina pectoris and significance there].

Objective: To investigate the effect of unfitrate heparin (UFH) and low molecular weight heparin (LMWH) on the expression of serum hepatocyte growth factor (HGF) during percutaneous coronary intervention (PCI).

Methods: Seventy patients with chronic unstable angina pectoris were divided into 2 groups: PCI group (n = 49, with at least one main coronary artery branch with stenosis > or = 70%) and non-PCI group (n = 21, with the main coronary artery branch with stenosis < 70%). UFH was used at the beginning of coronary angiography in both groups and LMWH was used after PCI only in the PCI group.

Relationship between hs-CRP, proMMP-1, TIMP-1 and coronary plaque morphology: intravascular ultrasound study.

Background: Rupture of unstable plaque with subsequent thrombus formation is the common pathophysiological substrate of the acute coronary syndrome (ACS). It is of potential significance to explore the blood indexes predicting plaque characteristics. Little studies have focused on this field.
