Object To understand pollen life of Cistanche deserticola Y.C.Ma in natural conditions. Methods To determine pollen viability of C. deserticola in natural state by pollen germination method in vitro.Results The optimum conditions of C. deserticolapollen germination are pollens in primary flowering time and a culture medium with 0.6% agar + 10% sucrose + 0.1% boric acid, cultured in 25 ℃, which is benefit to pollen germination and pollen tube growth; low temperature (4 ℃) is benefit to pollen short-dated storage and can prolong pollen life. Conclusion The study provides a theoretical basis for conserving better seed resources and artificial cultivating by pollen of C. deserticola.

ObjectiveTo study the relationship between the antitumor immunoreaction and the cell apoptosis in esophageal carcinoma.MethodsThe IL-1β converting enzyme, Fas and FasL protein were labeled by LSAB immunohistochemistric method in 46 cases of esophageal carcinoma, of which 13 cases were labeled by TdT mediated dUTP nick end labeling (TUNEL).ResultsThe positive rates of ICE, Fas and FasL proteins in the cancer nests were 78.26%, 60.87% and 47.83%. The expression of ICE protein was related to the histological grading of the cancer.Conclusions The expression of Fas, FasL protein may be related to the immunological escape of the cancer cell; the expression of ICE was related to the histological grading of the cancer.

Objective To study the effect of evidence-based nursing in patients with cerebral apoplexy in ICU by blind bedside spiral nasointestinal tube application.Methods To choose between September 2016 and September 2017 in our hospital ICU were 140 cases of patients with cerebral apoplexy as analysis object,randomly divided into two groups,two groups all use bedside blind spiral nose long intestinal tube technology,the control group using conventional nursing method for nursing,observation group using evidence-based nursing intervention,compared two groups of a success rate of catheter,accident to take off the tube (unscheduled decannulation rate),reflux hiccups,vomiting incidence of aspiration and patient satisfaction.Results The success rate of catheterization in the observation group was higher than that in the control group,and the incidence of accidental catheterization was lower than that in the control group.The incidence of reflux hiccup and vomiting aspiration was significantly lower than that in the control group,and the patient satisfaction was higher than that in the control group (all P＜0.05).Conclusion For patients with cerebral apoplexy in the ICU bed of blind plug spiral nasal bowel technology combined evidence-based nursing intervention,clinical effect is remarkable,improve the success rate of catheter,reduces the surprise success rate of tube,unscheduled tube drawing number,reduces the incidence of reflux hiccups,vomiting aspiration,improve patient satisfaction and quality of life.
