Objecteve To study the relation between the enhanced CT image parameters and metastasis, type of peripheral lung cancer. Methods The enhanced CT image parameters of 138 peripheral lung cancers confirmed by pathology were analyed retrospectively. Both plane scan and contrast-enhanced CT were performed in all the patients, and boundary CT value of each lung cancer was measured. Results Contrast-enhanced CT showed that peripheral lung cancer had big and bent peripheral vessels, and the peripheral density of tumor mass was correlated with its metastasis. The frequency of adenocarcinoma metastasis was higher than that of squamous carcinoma. Conclusion Contrast-enhanced CT was helpful for predicting the latent possibility of peripheral lung cancer metastasis.

Objective To observe the international obstetric services model to reduce the incidence of hypoxic ischemic encephalopathy( HIE) in natural childbirth neonatal. Methods A total of 360 maternals from February 2012 to May 2014 were selected, according to production inspection manual number, odd as the study group and even as the control group, 180 cases in each group. The study group adopts the scheme of new international obstetrics service mode, the control group used traditional obstetric services model. Rate of maternal natural childbirth, maternal satisfaction and incidence of HIE were compared between the two groups. Results The rate of childbirth maternal natural and satisfaction of the observation group were 88. 5%, 96. 0%, which were significantly higher than that of the control group (χ2 =6. 632, 4. 114,P<0. 05). Incidence of HIE in the observation group was 4. 19%, which was significantly lower than 10. 14% in the control group, the difference was statistically significant (χ2 =4. 267,P <0. 05). Conclusions International obstetric service mode can reduce the incidence of HIE in natural childbirth neonatal, which has a high value of popularization.
