Objective:To observe the efficacy of enteral nutrition during perioperation in elderly patients with gastrointestinal tumor.Methods:Forty cases with gastrointestinal tumor were randomized into the experimental group(n=20) and the control group(n=20).The experimental group was given nutritional support with Peptison liquid and was maintained for 7 days.The control group was treated with conventional methods.Results:The experimental group had faster recovery of gastrointestinal function as compared with the control group.The nutrition status and cellular immune function were ameliorated markedly in experimental group.Conclusion:The enteral nutrition in elderly patients with gastrointestinal tumor can promote the recovery of gastrointestinal function,ameliorate nutrition status and cellular immune function.

Objective:Deeper studies have been rarely reported on the characteristics and influencing factors of the psychological health of army nurses and on the measures for raising their ability of military stress management. To gain an insight into the psychological state of army nurses in the present military streamlining and to explore its countermeasures. Methods:We investigated the psychological state of 123 army nurses from 6 military hospitals by psychometrical methods and psychological interviews,and analyzed the results. Results:Of the total number of subjects,70.73% scored

Objective To assess the effect of low‐dose aspirin on endometrium after transcervical resection for severe intrau‐terine .Methods Eighty women after transcervical resection and foley balloon for severe intrauterine adhesions were divided into 4 groups randomly .Twenty cases in each group .Group A :fill jiale 3 mg ,3 times/day ,1 consecutive month ;Group B :fill jiale 3 mg ,3 times/day plus aspirin 50 mg ,1 time/day ,1 consecutive month ;Group C :fill jiale 3 mg ,3 times/day ,75 mg of aspirin ,1 time/day ,1 consecutive month ;Group D :fill jiale 3 mg ,3 times/day ,100 mg of aspirin ,1 time/day ,1 month in a row .Endometrial thickness , pattern of endometrium ,the resistance index(RI) and pulsed index (PI) were observed and recorded the menstrual blood volume . The endometrial cavity were performed through hysteroscope after one month .Results First ,all endometrial thickness in group B , C ,D on HCG day were thicker than group A ,there were significant difference(P< 0 .05) ;A‐type endometrium rate of group B ,C , D were higher than that of group A ,however ,RI and PI were lower than that of group A ,there had significant difference compared with group A(P< 0 .05) ;Second ,the menstrual blood volume have been great changed in group B ,C ,D ,there had significant differ‐ence compared with group A(P< 0 .05) ,there were no significant changes between the three group(P> 0 .05) ;Third ,the endome‐trial cavity in group B ,C ,D were recovery well(P< 0 .05) ,there were no significant changes between the three group(P > 0 .05) . Conclusion low‐dose aspirin combined fill jiale can significantly improve the growth of endometrial caused by intrauterine adhe‐sions cutting and recovery .

Objective To explore the epidemiological characteristics and cost structure of hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)in a tertiary comprehensive hospital in Xi'an from 2014 to 2023.Methods The first page information of AECOPD inpatients in a hospital from January 2014 to December 2023 was col-lected(n=6 748),and the distribution of their demographic characteristics and clinical characteristics as well as the composition of hospitalization expenses were retrospectively analyzed,and the structural change degree was used to analyze the structural change of hospitalization expenses in different years.Results AECOPD patients diagnosed and hospitalized accounted for 4.81 ‰ of all hospitalized patients in this institution from 2014-2023,the proportion of AECOPD inpatients showed a continuous downward trend during 10 years(x2=1 083.351,P＜0.001);The distribution of gender,occupation,medical payment meth-ods,and sources of AECOPD inpatients in different years showed statistical differences(P＜0.05);There is a statistical differ-ence in the seasonal distribution of AECOPD inpatients in different years(x2=157.328,P＜0.001);There is a statistical difference in the average length of hospital stay among AECOPD inpatients in different years(x2=83.463,P＜0.001);There were statistically significant differences in the proportion of hospitalizations,admission conditions,comorbidities or complications,history of drug allergies,and readmission plans among AECOPD patients in different years(P＜0.05);There is a statistical difference in the outcomes of hospitalized AECOPD patients in different years(x2=153.367,P＜0.001);The average hospital-ization cost of AECOPD patients gradually increased from 2014-2016,and gradually decreased from 2016-2023(P＜0.01);The hospitalization expenses of AECOPD patients in different years are mainly based on drug expenses and diagnostic expenses;The overall degree of structural change(DSV)of average hospitalization expenses for AECOPD patients from 2014-2022 was 41.62％,with the highest DSV of hospitalization expenses in 2012-2013(22.69％)and the lowest DSV in 2017-2018(4.23％);The proportion of drug expenses in the average hospitalization cost of AECOPD patients continued to decline,while diagnostic expenses,hygiene material expenses,medical service expenses,and nursing expenses showed an overall increasing trend from 2014-2023.Conclusion The proportion and mortality rate of hospitalized AECOPD patients have shown an overall downward trend in the past 10 years;The proportion of hospitalized AECOPD patients in the age group of 70-79 is the highest,mainly distributed in winter;The overall average hospitalization cost over the past 10 years has shown a downward trend,with drug and diagnostic expenses as the main components.Drug expenses have been decreasing year by year,while diagnostic expen-ses have been increasing year by year.This indicates that medical policy reform plays a significant role in optimizing the hospitali-zation cost structure and controlling unreasonable cost growth.
