Objective To evaluate comprehensively the effect of vibratory sputum ejectionmachine on patients by comparing the volume of vibratory sputum ejection machine and the traditional back percussion sputum expectoration.Methods Searching thoroughly Chinese Journal Full-text Database(CJFD),VIP CJFD,Wanfang Periodical Database,collecting the clinical randomized controlled trials of domestic vibratory sputum ejection machine and traditional back percussion sputum expectoration and employing RevMan5.0 processing software for statistical analysis.Results Vibration expectoration instrument is better than the traditional back percussion sputum expectoration.Conclusions Vibratory sputum ejection machine can increase the amount of expectoration drainage in patients and reduce pulmonary infection.

Objective To determine serum vascular endothelial growth factor (s-VEGF) and serum endostatin (s-endostatin) levels in patients with colorectal cancer after preoperative regional intraarterial chemotherapy (PRAC). Methods Peripheral venous blood was sampled preoperatively and postoperatively, and was assayed for VEGF and endostatin by ELISA. Results Patients' preoperative level of s-VEGF and s-endostatin elevated significantly, which was in close correlation with Dukes' stage. The level of s-VEGF and s-endostatin before chemotherapy elevated significantly compared with that on day 7 after chemotherapy and on postoperational day 1 and 14 after operation. In patients undergoing palliative resection, only the level of s-endostatin before chemotherapy was significantly higher than that on day 1 after operation. Conclusions PRAC, inhibiting angiogenesis, is of antitumor effect, the decrease of s-endostatin after chemotherapy may suggest the combination of chemotherapy and antiangiogenesis for a better antitumor effect.

Objective To evaluate the curative effect of compound nutrient assisted phototherapy on neonatal jaundice.Methods Neonatologists at seven hospitals participated in the study.A total of three hundred and twenty full-term newborns with high indirect bilirubin admitted to hospital from September 2017 to January 2018 were selected.One hundred and sixty-six cases in the observation group,and one hundred and fifty-four cases in the control group,all enrolled neonates were given single-sided,conventional intensity phototherapy.Observation group took compound nutrient at the same time.The average gestational age,age,birth weight of two groups before treatment were not significantly different.Serum total biilirubin,indirect bidirubin,liver function (ALT,AST) and phototherapy time were monitored before treatment and 3 days after treatment.Results The serum total bilirubin in the observation group was significantly lower than that of the control group after 3 days of treatment[(196.7 ± 57.2) μmol/L vs (216.5 ± 54.6) μmol/L],(t=3.17,P＜0.01).The indirect bilirubin in the observation group was significantly lower than that of the control group after 3 days of treatment [(176.3 ± 54.3) μmol/L vs (197.2 ± 52.9) μmol/L],(t=3.50,P＜0.01).The time of phototherapy of the children in the observation group was significantly shorter than that of the control group[(19.8 ± 14.4)d vs (22.9 ± 13.3) d],(t =2.00,P ＜ 0.01).Rash,fever,bronze disease,spilled milk,vomiting,abdominal distention,diarrhea,constipation,liver damage etc.were no significant difference the observation group and the control group(P ＞ 0.05).Conclusion Compound nutrients had good efficacy and safety in adjuvant phototherapy for neonatal high indirect bidirubin.

The reflective ability of nursing staff has been paid more and more attention, nurses' reflection can promote professional competence development, which also can improve clinical practice ability, knowledge expansion ability and innovation ability. Therefore this article reviews the current situation on nurses′ reflection, the assessment tools, the modes, forms, methods and types, future prospects of clinical nurses reflective practice, in order to provide reference and basis for the relevant research on the reflection practice of clinical nursing staff in China.
