Objective To investigate the incidence,influencing factors and clinical features of ischemic hepatitis.Methods Changes of serum transaminase and lactate dehydrogenase in patients with shock and respiratory failure were recorded in our hospital.Ischemic hepatitis was identified according to diagnosis guidelines,and its incidence was counted.Clinical data of patients with ischemic hepatitis were recorded.Results There were 53 cases diagnosed as ischemic hepatitis in 317 severe patients,including hemorrhagic shock,heart failure,respiratory failure,et al.The incidence was high in elderly patients aged over 70 years and male.Levels of alanine aminotransferase (ALT),AST and lactic dehydrogenase (LDH) were significantly increased 1-3 days after shock and respiratory failure,then reached to peak value 1-5 days [averaged (3.35±0.89) days] after shock and respiratory failure.Serum ALT was 869-4354 U/L,AST was 773-4833U/L and LDH was 1021-2662 U/L.Total bilirubin level was increased in 16 cases and the total bilirubin was 14-54 μmol/L.AST was declined to a point within 2 times the upper limit of normal range after 9-16 days,averaged (13± 1.6) days.Elevated transaminase level had no correlation with sex,age and pre-existing liver diseases.The time of enzyme changes had no correlation with sex but age and liver diseases.Patients aged ≥ 70 years had later AST peak and the recovery time was longer than younger patients (P＜0.01).Conclusions Ischemic hepatitis occurs mainly in men and elderly people.But advanced age and underlying liver diseases can affect the recovery time of transaminase in patients with ischemic hepatitis.

Objective To summarize the nursing experience on nosocomial infection in elderly patients with intra-aortic balloon pump (IABP) after coronary artery bypass grafting. Methods The clinical data of elderly patients who underwent coronary artery bypass grafting with application of IABP from April 2006 to February 2009 were retrospectively collected and analyzed. Results 29 patients suffered nosocomial infection in all 111 cases. The hospital mortality was much higher among patients with nosocomial infection than in patients without nosocomial infection (19 cases vs 11 cases). 87 positive strains were separated from 29 patients with nosocomial infection, which included 47 strains of gram-negative bacterial, 23 strains of gram-positive bacterial and 17 strains of fungi. Conclusions The nosocomial infection was one of the risk factors for hospital mortality in elderly patients with intra-aortic balloon pump after coronary artery bypass grafting. It is important to take effective nursing strategies to prevent the postoperative nosocomial infection in this population.

Purpose To detect the expression of FOXO3 in lung cancer specimens and lung cancer stem cell, for diagnosis and treat-ment of lung cancer. Methods Immunohistochemistry, semi-quantitative PCR and Western blot were used to detect FOXO3 protein expression in clinical specimens of lung cancer. PCR and Western blot verified FOXO3 mRNA and protein expression of lung cancer cells. Results Immunohistochemistry showed that the FOXO3 was significantly lower expressed in lung cancer tissues and the corre-sponding lung cancer stem cells;Detection of FOXO3 mRNA and protein by RT-PCR and Western blot showed both had significantly lower expression;as progression of the disease, there was a clear decreasing trend, in which negative expression rate of FOXO3 protein accounted for 66. 7% in all patients;at the same times, the rate of the expression gradually decreased with loss of differentiation and metastasis of the tumor. Conclusions FOXO3 shows low expression in lung tissue and lung cancer stem cells, while it is closely relat-ed to the degree of malignancy and lung cancer metastasis, which may be a new target for the treatment.
