Objective To explore the effect of pregnancy outcome with cervical cold knife conization in pa -tients with early stage cervical cancer .Methods 23 patients with cold knife conization and 21 patients with radical trachelectomy were collected .The pregnancy outcome and perinatal infants between the two groups were compared . Results The pregnancy rate was 82.6%in the observation group,71.4%in the control group,there was statistically significant difference(χ2 =8.654,P=0.002);the section rate was 37.5% in the observation group,30.8% in the control group,there was statistically significant difference (χ2 =9.645, P =0.000 );10 cases of term delivery (62.5%)and birth weight was(3.27 ±1.15)in the observation group,term delivery(69.2%)and birth weight was (2.81 ±0.96)in the control group,proportion and birth weight were statistically significant differences (χ2 =11.671, P=0.000)(t =9.683,P=0.000);there were statistical significance in the outcome of pregnancy (Fisher P=0.036)and perinatal infants(Fisher P=0.034)among patients with different cervical conization height;the relapse rate was 4.4% in observation group,9.5% in the control group,the relapse rate of the two groups had significant difference(Fisher P =0.039).Conclusion Compared with radical trachelectomy ,patients treated by cold knife conization has high pregnancy rate and high cesarean section rate ,which can influence the outcome of pregnancy and perinatal infants .

Nitric oxide (NO) is a vascular endothelium-derived relaxing factor.NO inhalation therapy is widely used in the field of neonatology.When NO acts as selective pulmonary vasodilation,it can reduce pulmonary arterial pressure and improve oxygenation.When NO serves as a major regulator of cerebral vasomotor factor,it may have physiological and pathological impact in cerebral ischemia-reperfusion injury.So NO has a wide range of applications in persistent pulmonary hypertension of the newborn,bronchopulmonary dysplasia,hypoxia ischemic encephalopathy.With the recently in-depth study of NO,its biological role has more and more clinical attention in the field of neonatology and has broad valid prospects.However,NO has some side effects which still have some controversial aspects of the application in premature,especially in very low birth weight children.The article focused on the mechanism and clinical applications of NO in the neonatal disease.

Objective To investigate the clinical effect of integrated care model in improving the quality of life and enthusiasm of treatment in patients with cardiovascular diseases. Methods 60 patients in department of cardiology adopting integrated care from September 2008 to April 2011 were chosen as the observation group.60 patients with ordinary care were set as the control group.The quality of life and the situation for enthusiasm of treatment were taken for statistical analysis. Results Patients with good quality of life in the observation group was 39 cases (65.00％),more than 21 cases (35.00％) in the control group.Patients obtaining effective treatment result in the observation group was 48 cases (80.00％) and 15 cases (25.00％) in the control group,there was significant difference.It was statistical significant.Adherence to medication,reasonable diet,adequate exercise and proper understanding of disease status in the observation group were significantly better than the control group.
