[Values of fractional exhaled nitric oxide in the diagnosis of chronic cough].
To evaluate the diagnostic value of fractional exhaled nitric oxide (FeNO) in the diagnosis of chronic cough. ⋯ There are significant differences between the FeNO levels of different causes of chronic cough. A marked elevation of FeNO level helps to make a final diagnosis of CVA or EB. FeNO test is useful for making the diagnosis and differential diagnosis of chronic cough in clinic practices.

[Percentages and functions of natural killer cell subsets in peripheral blood of patients with severe aplastic anemia].
To analyze the percentage and functional changes of natural killer (NK) cell subsets in peripheral blood of severe aplastic anemia (SAA) patients before and after immunosuppressive therapy (IST) so as to evaluate the relationships between these changes and hematopoietic functions and explore the role of NK cells in the pathogenesis of SAA. ⋯ The lowered percentage of NK CD56(bright), CD56(dim) cells and a higher expression of perforin may cause the over-function of T lymphocytes and thus lead to hematopoietic failure in SAA.

[Preventive effects of ischemic postconditioning and penehyclidine hydrochloride on gastric against ischemia-reperfusion injury in rats].
To investigate the protective effects of ischemic postconditioning and penehyclidine hydrochloride on gastric injury induced by ischemia-reperfusion of lower limb in rats. ⋯ The combination of ischemia postconditioning and postconditioning with penehyclidine hydrochloride can protect the gastric from ischemia-reperfusion injury induced by ischemia reperfusion of the lower limbs in rats, the main mechanism may be reducing post-ischemic oxidative damage, inflammatory reaction, amelio-rating microcirculatory and cellular energy metabolism et al. Additionally, this study found that the protective effects of penehyclidine hydrochloride on gastric injury induced by ischemia reperfusion of the lower limbs, were better than ischemic postconditioning, and the mechanism might be related to its anti-inflammatory effect, antioxidant action and prevention of cell injury et al.

[Early, middle and long-term clinical outcomes of coronary artery bypass grafting for left main coronary stenosis].
To evaluate the early, middle and long-term clinical outcomes of coronary artery bypass grafting (CABG) for a special subset of left main coronary stenosis (LMS). ⋯ The CABG procedure for LMS carries a relative high mortality. However preoperative statin therapy may offer such protective effects as lowering the all-cause mortality rate and reducing the prevalence of new atrial fibrillation or flutter and disabling stroke.

[Management of femoral neck fracture post total knee arthroplasty].
To investigate the risk factors, management and prognosis of femoral neck fracture post total knee arthroplasty (TKA). ⋯ Femoral neck fracture following TKA is usually caused by a low-energy injury. Osteoporosis is one of its high-risk factors. Knee instability is associated with ipsilateral femoral neck fracture. Clinically it can be treated by internal fixation or hip arthroplasty. And internal fixation of femoral neck fracture frequently induces femoral head necrosis. And femoral head replacement is applicable.
