Objective To observe the clinical effect of maintenance chemotherapy by pemetrexed in advanced non-small-cell lung cancer. Methods 60 patients with advanced non-small-cell lung cancer (stage Ⅲb~ Ⅳ) were randomly divided into observation group and control group , all the patients showed complete or partial remission after receiving 4 cycles of induction chemotherapy. Observation group was given pemetrexed maintenance (500 mg/m2 on days 1 every 21 days) until first disease progression, control group was given best supportive care . Progression free survival ( PFS ) , overall survival ( OS ) and adverse reaction were observed . Results PFS and OS of observation group were significantly higher than control group, PFS was (7.3 ± 1.20) vs (3.5 ± 1.13) months, OS was (12.2 ± 1.14) vs (7.1 ± 1.23) months, the difference was statistically significant. The main side effects were fatigue and leucopenia which were tolerable. Conclusion Maintenance therapy with peme-trexed following initial therapy was feasible, and extended the PFS and OS, and shows a favorable toxicity profile.

Objective To assess the value of ultrasonic elastography in the diagnosis of special type breast cancers. Methods Routine ultrasonograms, color Doppler flow images and elasticity images of 13 patients with special type breast cancer confirmed surgical pathologically were retrospectively analyzed. Results The score of mucinous carcinoma, inflammatory breast cancer (1 patient), lactation breast cancer, invasive micropapillary carcinoma, tubular carcinoma and invasive lobular carcinoma (2 patients) were 4-5. The score of 1 patient of invasive lobular carcinoma was 1 and 1 patient of lactation breast cancer was 3. The characteristics of color Doppler flow imaging of majority patients were varies, while no obvious lesion was observed in Paget's disease. Conclusion Ultrasonic elastography is helpful to the diagnosis of inflammatory breast cancer, lactation breast cancer, invasive micropapillary carcinoma of the breast, papillary carcinoma and tubular carcinoma of the breast. Early diagnosis of Paget's disease still depends on pathology.

Objective To investigate the preventive effect of health education on prevention of vaginitis among Guangzhou ’ s career women.Methods 479 career women with confirmed diagnosis of vaginitis in 2013 were cured and followed up for 1 year.Pa-tient were divided into Control Group (n=202) and Observation Group (n=277) according to whether accompanied the health edu-cation on prevention of vagnnitis.The recurrence rate of vaginitis during the 1 -year follow -up was compared between the two groups.Results In Control Group, 192 patients (95.05%) finished the follow -up, and in Observation Group, 260 patients (93.86%) finished the follow-up, there was not statistical difference in accomplishment ratio of follow -up (p>0.05).The recur-rence of rate of vaginitis was statistical higher in Control Group (72/192, 37.50%) than that in Observation Group (64/260, 24.62%) (P<0.05).Conclusion Health education could reduce the recurrence rate of vaginitis significantly.

Objective To study the effect of post-hospital nursing intervention on blood pressure and medication compliance of hypertensive patients.Methods One hundred hypertensive patients were divided into the observation group and the control group in equal number by the random digits table.Those in the control returned regularly for consultations and took medicine under doctor’s supervision and those in the observation group received out-of-hospital nursing intervention apart from the nursing done to the controls. The blood pressure and medicine-taking compliance were assessed in 6 months.Result The observation group was significantly better than the control one in terms of blood pressure and medicine-taking compliance(both P<0.05).Conclusion The post-hospital systematic nursing intervention may help to control the blood pressure of hypertensive patients and enhance their medicine-taking compliance so as to improve the curative effect.
