Objective To explore the inter-fraction setup errors and affecting factors from data of daily fan-beam megavoltage computed tomography(MVCT). Methods A total of 37consecutive NPC patients treated with tomotherapy were hospitalized during the period of February 2015 to September 2015. For each patient,one MVCT scan was obtained after conventional positioning ,online correction and tomotherapy delivery daily ,and the scans were put into the planning computed tomography to determine inter-fraction setup errors. The MPTV was calculated with the equation:MPTV=2.5∑+0.7σ(∑:systematic error;σ:random error). Results The average absolute errors of the inter-fraction were(2.102 ± 0.0406)mm,(1.490 ± 0.0348)mm,(1.306 ± 0.335)mm and(1.392 ± 0.0384)° at three dimensions. The total MPTV accounting for inter-error was 3.4675 mm,2.9795 mm,and 2.8885 mm. Gradual increases in both inter-fraction three-dimensional displacement were observed with time and treatment(P < 0.05). Univariate analysis revealed that weight loss and retraction of neck lymph nodes were affecting factors of set-up errors. Conclusions 3 mm margins uniformly expended from clinical target volume to planning target volume may not be suitable. The personalized margin should be adopted for the design of IMRT planning. Displacement increases as a treatment course is prolonged.

Objective To investigate antimicrobial resistance of Escherichia coli (E.coli)and Klebsiella pneumoniae (K.pneumoniae),antimicrobial use density(AUD),as well as relation between antimicrobial resistance and AUD in a ter-tiary first-class hospital.Methods Antimicrobial resistance rates of clinically-isolated E.coli and K.pneumoniae,AUD of carbapenems and quinolones,as well as relation between resistance and AUD in 2013-2015 were statistically analyzed. Results Correlation analysis of antimicrobial resistance of bacteria and AUD showed that the decrease in resistance rate of E.coli to levofloxacin was related to the decrease in the use density of quinolones(r=0.61,P=0.03);increase in resist-ance rate of K.pneumoniae to imipenem was related to the increase in the use density of carbapenems(r=0.78,P<0.01). Conclusion Antimicrobial use is one of the causes of bacterial resistance,management on antimicrobial use needs to be strengthened to reduce the threat of bacterial resistance to human health.

Objective To evaluate the inter-fraction setup error during the treatment with megavoltage computed tomography (MVCT) and provide theoretical basis for clinical target volume-planning target volume (CTV-PTV) margins for nasopharyngeal carcinoma (NPC) patients treated with tomotherapy.Methods Thirty-seven consecutive NPC patients treated with tomotherapy were prospectively enrolled for the study between February 2015 and September 2015.For each patient,one MVCT scan was obtained after conventional positioning,online correction and tomotherapy delivery daily,and the scan was registered to the planning CT to determine inter-fraction setup error.The expanding margin for PTV (MPTV) was calculated with the recipe:MPTV =2.5∑ + 0.76 (∑:systematic error;6:random error).Results The average absolute errors of the inter-fraction were (2.102 ± 0.040 6) mm,(1.490 ± 0.034 8) mm,(1.306 ± 0.335) mm and (1.392 ± 0.038 4) ° in the three dimensions.Gradual increases in both inter-fraction three-dimensional displacement were observed with time and treatment (P ＜ 0.05).The total MPTV ac counting for inter-error were 3.467 5 mm,2.979 5 mm and 2.888 5 mm.Conclusions Tomotherapy irradiation technology personalized MPTV should be adopted for the design of tomotherapy plan.Displacement increased as a function of time.

Colaizzi′s data analysis method was performed to analyze and conclude the theme.Results Eight themes of the application were obtained from the experience of 22 patients:economic difficulties,weak family support,serious treatment side effects,tortile religious faith,incorrect internet information,indifference in combined treatment,complex formalities and complications. Conclusions The affecting factors,such as economic difficulties,are the most frequently endorsed barrier to combined treatment compliance. The management of affecting factors is critically significant to increase patients′ compliance to comprehensive treatment. Medical staff should offer individual economic and medical information as well as emotion supports,and encourage breast cancer patients to actively complete the comprehensive treatment.

Objective:To explore the effects of individualized exercise prescription in critically ill patients during enteral nutrition.Methods:From January to August 2018, we selected 120 critically ill patients admitted to the General Surgery Intensive Care Unit (ICU) of General Hospital of Eastern Theater Command. According to admission time, patients were divided into control group and observation group, with 60 cases in each group. Control group used the conventional chest physical therapy, exercise program for passive and active functional exercise of limbs. Observation group implemented the individualized exercise prescription to implement functional exercise orders. After daily rounds, doctors and nurses assessed the condition of the day by combining patient's basic condition and prescribed the individualized exercise prescription, including functional exercise items, requirements, dosages and frequency, performed by a full-time nurse. We compared the muscle strength of patients between two groups with the MRC scores, and observed the intolerance, number of interruptions of enteral nutrition feeding and the ICU hospitalization time during enteral nutrition between two groups.Results:After 168 hours and 366 hours, the differences of MRC scores between two groups were significant ( P<0.05) . After 14 days of intervention, the serum total protein, hemoglobin and body mass index (BMI) of observation group were higher than those of control group also with statistical differences ( P<0.05) . The number of cases of abdominal distension, gastric retention, the total number of intolerance and the number of feeding interruptions during enteral nutrition in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . The ICU hospitalization time of patients of observation group and control group were (25.28±5.42) d and (27.94±5.65) d respectively also with a statistical difference ( P<0.05) . Conclusions:The individualized exercise prescription functional exercise intervention strategies is beneficial for critically ill patients to improve muscle strength, nutritional indicators, avoid rapid decline in BMI, reduce feeding intolerance and the number of feeding interruptions, ensure continuous implementation of enteral nutrition, and shorten patients' ICU hospitalization time so as to promote accelerated recovery of patients.

Objective To explore the effect of the blood purification combined with early enteral nutrition on the accelerating rehabilitation in critical patients in surgery .Methods Two hundred and thirty-nine critical patients in ICU were chosen , and the patients from June 2011 to May 2012 were divided into the control group ( n=118 ) , and from June 2012 to May 2013 were divided into the observation group ( n=121 ) .The control group received the enteral nutrition after the recovery of intestinal function , and bedside continuous blood purification ( CBP) on the occurrence of acute kidney injury .The observation group received the early enteral nutrition and the routine CBP 24-48 h after the ICU .The therapeutic effect was compared between two groups . Results The level of albumin in the observation group was (34.33 ±4.85)g/L before the treatment, and was (39.72 ±4.72)g/L after the treatment, and the difference was statistically significant (t =-9.219,P <0.01).The level of albumin in the control group was (34.86 ±4.70) g/L before the treatment, and was (34.04 ±4.62) g/L after the treatment, and the difference was not statistically significant (t =1.957,P >0.05).The difference was found in the level of albumin after the treatment between two groups (t=-9.397, P<0.01).The times of hospitalization in ICU, mechanical ventilation and the CBP treatment in the observation group were respectively (17.68 ±2.96) d, (8.49 ±2.35) d, (78.13 ±12.72) h, and were lower than (18.83 ±3.46)d, (9.48 ±2.86) d, (126.50 ±19.56) h in the control group, and the differences were statistically significant (t=2.768, 2.163, 22.602, respectively;P<0.05).Conclusions Application of the blood purification combined with early enteral nutrition in the critical patients in surgery can effectively improve their nutritional index , and reduce the loss of albumin , and shorten the times of mechanical ventilation and hospitalization in ICU , and accelerate the rehabilitation .

Objective:To explore the influences of abdominal pressure monitoring in different positions on patients with abdominal hypertension.Methods:From January to June 2019, convenience sampling was used to select 100 critical ill patients with abdominal hypertension who were admitted to the Intensive Care Unit of General Surgery of the General Hospital of Eastern Theater Command as the research object. The abdominal pressure was monitored by indirectly measuring the bladder pressure. We measured the abdominal pressure when patients were in stable condition and in 30° lying position, 45° lying position as well as the supine position respectively, recorded the single measurement data of the patient's abdominal pressure in different positions, and performed another position measurement rest for 15 minutes after changing the position.Results:The abdominal pressures measured in 100 critical ill patients with abdominal hypertension in the supine position, 30° lying position and 45° lying position were (19.18±3.95) , (23.40±3.87) and (28.17±3.60) mmHg (1 mmHg=0.133kPa) respectively, and the difference was statistically significant ( P<0.01) . The abdominal pressure monitored in the supine position was lower than those in the 30° lying position and 45° lying position, the difference was statistically significant (supine position vs. 30° lying position, P<0.01; supine position vs. 45° lying position, P<0.01) . The abdominal pressure monitored in the 30 ° lying position and 45 ° lying position was higher than that in the supine position by one to two levels. With the increase of the bed head elevation angle, the abdominal pressure value is getting higher and higher, regardless of the level of abdominal pressure in critical ill patients with abdominal hypertension. Conclusions:The abdominal pressure monitoring in actual positions can reflect the true situation of the patient well, and can provide a relatively true and reliable monitoring data for clinical nursing decision-making.
