Pulmonary fibrosis is an interstitial lung disease caused by different pathogenic factors. It has the characteristics of high morbidity and poor prognosis, which seriously affects the quality of life of patients. However, its pathogenesis has not yet been fully elucidated. Surfactant protein(SP)-A and SP-D are lipoprotein complexes distributed at the air-liquid interface of alveoli, synthesized and secreted by alveolar type Ⅱ epithelial cells and bronchiolar cells. They are important parts of the innate immune system, which participate in the host defense process through a variety of regulatory methods, and play an important role in regulating cell apoptosis and lung inflammation, promoting the process of epithelial repair and maintaining the stability of alveolar structure. The disorder and mutation of SP-A and SP-D may be the influencing factors of the pathogenesis of pulmonary fibrosis. Serum SP-A and SP-D levels are differentially expressed in patients with pulmonary fibrosis and normal healthy individuals, and are related to the severity of pulmonary fibrosis. They are considered to be a class of biomarkers that sensitively reflect lung epithelial cell damage and can be used in the diagnosis, treatment and prognostic evaluation of pulmonary fibrosis.

Atrial fibrillation is an epidemic in Asia that is increasingly prevalent. Apart from stroke risk stratification and management of anticoagulation, physicians managing this group of patients also need to determine an optimal strategy in terms of rate or rhythm control. With new techniques of catheter ablation to maintain patients in sinus rhythm, patients with atrial fibrillation now have more options for treatment, on top of pharmacological methods. This paper aims to review the current evidence for rate and rhythm control in both general patients and subgroups of interest commonly encountered in clinical practices such as obesity, heart failure and thyroid disease.

Objective To establish a model of cervical spondylosis in rats. Methods Sixty SD rats (four months old) were ran-domly divided into control, muscle imbalance and posterior column instability group, ten rats in each group. Then the degeneration of X-ray film and motion function were evaluated by oblique board test. Results After analyzed the cervical films of control groups, the nature curve still existed, vertebral clearance had no abnormal. No ostensis spurs or ossifies in Luschka joint and joint processes were found. But in mus-cle imbalance and posterior column instability groups, the nature curve was disappeared or stiff, vertebral clearance were stenosis, osteosis spur formed, ossify or sclerosis emerged in Lnschka joint and joint process. Compared with control group in oblique board test, the muscle force decreased in muscle imbalance and posterior column instability group. There were no statistic significant difference between 2 and 4 months of control group, and also no difference in muscle imbalance and posterior column instability group, but there were significant differ-ence in 2 and 4 months of muscle imbalance and posterior column group. Conclusion Not only cervical posterior column instability but also muscle imbalance could result in cervical spendylosis, both muscle force balance and posterior column were important factors in maintaining spine stability.
