Objective To investigate the effects of two sputum aspirations on old critical patients.Methods Sixty elderly critical patients were divided into the experiment group and control group in equal number.The former group received sputum aspiration by oropharynx airpipe and the control group by oronasal airpipe.The two groups were compared in terms of sputum aspiration effect and saturation of blood oxygen.Result The observation group was significantly better than the control group in terms of sputum aspiration effect and saturation of blood oxygen(both P<0.05).Conclusion Sputum aspiration by oropharynx airpipe is effective in the aspiration of secretions from respiratory tract and the reduced effect of saturation of blood oxygen.

Purpose:To improve the diagnostic accuracy of gastric submucosal tumor whose endoscopy was negative. Methods:Six cases of gastric submucosal tumor with “negative” results of endoscopy were analyzed. Results:Before operation 3 were recieved by medicinal management, 5 were diagnosed as malignant tumor by CT, 2 were shown to be tumor by ultrasound. There were 3 gastric lymphoma, 1 gastric adenocarcinoma, 1 gastric Schwannoma and 1 gastric leiomyosarcoma confirmed by postoperational pathologic diagnosis. Conclusions:If suspicion remains in endoscopy diagnosis, procedure should involve careful physical examination, CT, B US, GI and so on to improve the diagnostic accuracy. [

Objective To analyze the variations and influencing factors of hospitalization expenditure of cervical cancer patients among urban employees in Beijing from 2006 to 2010,and to provide evidences for developing reasonable measures of medical expenses control.Methods Based on the hospitalization expenditure data of 1146 cervical cancer cases,the paper probed into the changes of hospitalization age and hospitalization expenditure,and the influencing factors of hospitalization expenditure by means of descriptive analysis and multiple stepwise regression.Results The last 5 years witnessed no significant change in the first hospitalization age of cervical cancer patients,rise of hospitalization age,gradual rise of the hospitalization expenditure per time along with their age groups,as well as a rising trend of the average hospitalization expenses,average drug cost and proportion of average drug cost year by year.Results of the multiple stepwise linear regression showed that days of stay,proportion of drug cost and surgery or not as important influencing factors for hospitalization expenditure.Conclusion Hospitalization expenditure of cervical cancer keeps growing.Against this background,reasonable shortening of the days of stay,reasonable setup of an appropriate proportion of out-of-pocket payment,and reduction of the proportion of drug costs become effective means to reduce hospitalization expenditure.

OBJECTIVE To improve the administrative and controlling quality of hospital acquired infection(HAI),practice all kinds of works of HAI and decrease the incidence rate of it.METHODS We should strengthen leading power,perfect constitution and administration web,make project workable,intensify education of HAI,improve all medical staff administrative consciousness and whole quality of professional people of HAI,reinforce precaution and manipulation,and erect system of informational feedback.RESULTS All kinds of works of HAI were improved and medical staff administrative consciousness of HAI was enhanced through administration,and we could ensure the effects of sterilizing and killing bacteria.CONCLUSIONS We could carry out all kinds of institutions of HAI through administrative system of standard-check-reward and punish.

Presently,studies of onset,development and tumor drug resistance of osteosarcoma were few.Further studies on tumor animal models can provide a promising basis for treating osteosarcoma.Commonly used animal models of osteosarcoma include mouse,rat,rabbit and dog.Organs of rats are similar to human,so does genotype.Dogs can spontaneously develop osteosarcoma,which is similar to human,and are frequently used as spontaneous tumor models.However,there are some differences in biological features,pathogenic mechanism and histology.With the development of studying,there will be more and more new animal models in accordance with human osteosarcoma characteristics.The present study served to review methods of establishing models,characteristics and detailed application of animal models of osteosarcoma.

With the application of gene editing in medical treatment,food engineering,environmental protection,agriculture and forestry,it gives rise to a wide range of potential social risks.Both the advanced aspects and defects of this technology bring complicated social conflicts.It is undoubtedly crucial to coordinate the conflict of interests of all parties,improve the legal system and avoid the harmfulness and blindness of gene editing.Meanwhile,only that the ethical,legal and social concerns are introduced will govern the technical risk as a necessary condition in order to attain a virtuous cycle of technological improvement and social prosperity.

Objective To analyse the effect of hedyotisdiffusa on expressions of apoptosis related protein Fas , caspase3 and caspase7 in Renca renal cell carcinoma of model mice.Methods One hundred and twenty BALB/C male mice were randomly divided into normal control group, model control group, interleukin group, hedyotisdiffusa group, 30 mice in each group, half male and female.Excepted for normal control group , renal cell carcinoma models were established in the other groups , and were given corresponding drug treatment.The tumor size and weight , and the tumor inhibition rate of all mice were observed, and the expression levels of Fas,FasL,caspase3 and caspase7 were detected.Results Compared with model control group, the tumor size and weight were lower , the tumor inhibition rate were higher , the positive expression rates and protein levels of Fas were higher , the positive expression rates and protein levels of FasL were lower, the positive expression rates and expression levels of Caspase3,Caspase7 protein were higher in the mice of interleukin group and hedyotisdiffusa group, all with significant differences ( P<0.05 ).The above indicators in hedyotisdiffusa group were significant improved compared with interleukin group (P<0.05).Conclusion The hedyotisdiffusa can effectively promote the expressions of apoptosis related protein Fas,caspase3 and caspase7 in renal cell carcinoma of model mice, inhibit the expression of FasL protein, improve the tumor suppression rate.

Objective To investigate the influence of early postoperative enteral nutrition on the immunologic function and inci-sion infection in the patients with colorectal cancer .Methods 81 postoperative cases of colorectal cancer were randomly divided into the early parenteral nutrition(41 cases) ,and the early enteral nutrition(40 cases) by the random number table method .The anal ex-haust time ,ambulation time and occurrence situation of incision infection ,etc .were compared between the two groups ,and the im-munological indexes changes were also compared .Results Postoperative anal exhaust time ,bed activity time and the occurrence rate of incision infection in the early enteral nutrition group were significantly lower than those in the early parenteral nutrition group (P<0 .05);Th1/Th2 and lymphocyte count in the early enteral nutrition group were significantly higher than those in the early parenteral nutrition group(P<0 .05) .Conclusion The early postoperative enteral nutrition support in the patients with colorectal cancer can effectively improve the body's immune function and is an ideal method of nutritional support .

Objective To explore the relationship between work engagement and job-person fit among nurses.Methods 465 nurses from five first-class general hospitals in Chengdu were assessed by the Utrecht Work Engagement scale(UWES)and the Areas of Worklife Survey(AWS).Results The mean value of work engagement among nurses was (3.21±1.09).Work engagement and job-person fit were positively related.Regression analysis suggested that job-person fits were significant predictors of nurses'work engagement.Exactly,value fit,workload fit,control fit and fairness fit were effective predictors of vigor.Value fit,fairness fit,reward fit and workload fit were effective predictors of dedication.Value fit,control fit,fairness fit and community fit were effective predictors of absorption.Conclusions The work engagement in nurses was at the moderate level.Job-person fits were powerful predictors of work engagement.Good fit among the six areas of work life can improve the work engagement among nurses.
