  • Review on Diagnosis and Treatment of Giant Coronary Artery Aneurysm

    The diameter of the giant coronary artery aneurysm is at least 4 times bigger than that of the normal coronary artery and 2-3 times bigger than that of the normal coronary artery aneurysm. Giant coronary artery aneurysm is rare in clinic with a reported morbidity which is less than 0.3%. Just like ordinary coronary artery aneurysm, coronary artery atherosclerosis is the main cause of the giant coronary artery aneurysm. Most giant coronary artery aneurysms are asymptomatic, but some patients may have heart-related clinical emergency in short term and may have thrombosis which can lead to embolism and fistula which can cause rupture in long term. Surgical treatment is the first chioce for giant coronary artery aneurysm now. However, the interventional therapy will also be an important way to treat the disease in the future. In this article, we review the diagnosis, clinical manifestation, treatment and other aspects of giant coronary artery aneurysm as follows.

  • Atrial Tachyarrhythmias after Cardiac Surgery: Incidence, Risk Factors, and Therapy

    Atrial tachyarrhythmias is a known complication after cardiac surgery and represents a major cause of morbidity, increased length of hospital stay, and economic costs. Atrial fibrillation is the most common heart rhythm disorder. And it is often associated with other atrial tachyarrhythmias, such as atrial flutter (AFlu), premature atrial complexes, and multifocal atrial tachycardia. Postoperative atrial fibrillation is often self-limiting, but it may require anticoagulation therapy and either a rate or rhythm control strategy. We provide a complete and updated review about mechanisms, risk factors, and treatment strategies for the main atrial tachyarrhythmias (atrial fibrillation).

  • Effects of Laparoscopic Resection on Systemic Stress Responses in Colorectal Cancer Patients

    ObjectiveTo investigate the systemic stress responses after laparoscopic resection in colorectal cancer patients.MethodsSixty patients were randomized into the laparoscopic resection group (30 cases) and open resection group (30 cases) from October 2001 to September 2002 in our hospital.Analgesic dosages, recovery time of intestinal peristalsis, postoperative temperatures, C reactive protein(CRP), IL6 and white blood cell (WBC) counts were recorded after operation. ResultsThe changes of postoperative temperatures and WBC counts showed no significant difference between two groups.But in the laparoscopic resection group, the recovery time of intestinal peristalsis, postoperative analgesic dosages, CRP and IL6 significantly decreased (P<0.01,P<0.05).ConclusionCompared with traditional open resection, laparoscopic resection of colorectal cancer can diminish the systemic stress responses and decrease the injury to patients.

  • The Alteration of Plasma Calcitonin Gene Related Peptide Level During Thrombolytic Therapy in Patients with Iliofemoral Venous Thrombosis

    ObjectiveTo probe plasma calcitonin gene related peptide (CGRP) levels during thrombolytic therapy in patients with iliofemoral venous thrombosis in order to investigate its regularity of the alteration and its clinical significance.MethodsFifty patients with acute iliofemoral venous thrombosis and 30 patients with chronic iliofemoral venous thrombosis were given urokinase and prostaglandin E1 from veins for 15 days. The CGRP levels were determined by radioimmunoassay before treatment and on the 6th hour, 1st day, 3rd day, 7th day, 14th day, 30th day after treatment.ResultsThe plasma CGRP levels were increased in patients with acute iliofemoral venous thrombosis compared with the contrast ones. The CGRP levels in serious group was lower than those in mild group. However, the CGRP levels of 30 chronic patients and 12 patients who received the second course of thrombolysis as on effective were not different from those of contrast ones. The plasma CGRP levels were increased at the 6th hour,reached the peak at the 3th day and returned to normal at the 14th day after thrombolytic therapy in acute group which just consistent with the therapeutic effectiveness.ConclusionIt is helpful to judge whether the thrombolytic therapy is effective and the illness has come to chronic stage according to the levels of plasma CGRP in patients with iliofemoral venous thrombosis.

  • Objective Monitoring of Neonatal Nosocomial Infection and Analysis of Antibiotic Resistance

    ObjectiveTo explore the risk factors for neonatal nosocomial infection and the pathogen resistance, in order to provide the basis for hospital infection control. MethodsSurveillance of hospital infection in newborns hospitalized for more than 48 hours were carried out from January to December 2012, and the risk factors for hospital infection were analyzed. ResultsThere were 54 newborn cases with neonatal nosocomial infection, and the infection rate of newborns was 1.25%. The major infection sites were respiratory tract (66.7%), gastrointestinal tract (18.5%), skin and soft tissues (9.2%). Birth weight (χ2Trend=126.88, P<0.001), hospitalization days (χ2Trend=106.89, P<0.001), invasive operation (χ2=5.338, P=0.021) were the major risk factors. A total of 54 strains of pathogenic bacteria were isolated from 54 newborn cases with neonatal nosocomial infection. Twenty-three strains of gram-positive bacteria accounted for 42.6%, which were generally resistant to penicillin and large ring lactone class antibiotic drugs. Thirty-one strains of gram-negative bacteria accounted for 57.4%, which were mainly resistant to the three generations of cephalosporins. ConclusionThe hospital infection rate of newborns is low. Birth weight, hospitalization days and invasive operation are the major risk factors for neonatal nosocomial infection.

  • Influence of Genders on Activity of Nuclear Factor-Kappa B in Lungs in Endotoxemic Rats

    Objective To investigate influence of genders on the activity of nuclear factor-kappa B (NF-κB) in lungs of endotoxemic rats. Methods Twenty female and 20 male Wistar rats were randomly divided into four groups as follow: female control group (n=10), male control group (n=10), male endotoxemic group (n=10), and female endotoxemic group (n=10). The endotoxemic rats model was made by injecting lipopolysaccharide (5 mg/kg) into the abdominal cavity. Tissue samples were collected from the lungs in different groups and electrophoresis mobility shift assay was used to measure the activity of NF-κB. The levels of serum TNF-α and estrogen were measured at the same time. Results There was no significant difference between the activities of NF-κB in male and female control groups (1.33±0.24 vs 1.47±0.40), and there was also no significant difference between other items in these groups as well (Pgt;0.05). Yet, the activity of NF-κB (female: 12.10±2.89; male: 19.53±2.12) and the level of TNF-α 〔female: (4.10±0.72) ng/ml; male: (6.37±1.29) ng/ml〕 were significantly increased after injection of lipopolysaccharide (Plt;0.01), and the indices in female group were significantly lower than those in male group (Plt;0.01). Correlation analysis showed that there was a positive relation between the activity of NF-κB in lungs and the level of TNF-α (female: r=0.921 1, P=0.013; male: r=0.907 2, P=0.017), and there was a negative correlation between the activity of NF-κB and the level of estrogen (female: r=-0.887 5, P=0.017; male: r=0.872 3, P=0.022) in both male endotoxemic group and female endotoxemic group (Plt;0.05). Conclusion Gender may be one of the factors that influence the activity of NF-κB in the lungs of endotoxemic rats. While  on the other hand, endogenous estrogen may protect the lungs of endotoxemic rats from injury by inhibiting the activity of NF-κB.
