Objective To study the influence of preoperative nutritional status for postoperative recovery effect of patients with colorectal cancer. Methods Selected 395 patients with colorectal cancer from Feb 2008 to Jan 2009, evaluated their preoperative nutritional status by NRS-2002, and then divided them into three groups according to the NRS-2002 values. Compared the indexes which indicated postoperative recovery effect among the three groups. Results The nutritional risk level were related with the time of postoperative pulled out the catheter and plasma drainage, the time of consumption, exhaust and defecation and the length of hospital stay. There was no significant correlation between the nutrition risk score and the time of pulled out the stomach robe and getting out of bed. Conclusions There were some influence of preoperative nutritional status on postoperative recovery effect of patients with colorectal cancer, nurses should emphases the preoperative nutrition evaluation and then carry out related nutritional support and associated nursing cares.

Objective To explore the prevalence of health literacy in China in 2011-2013.Methods The eligible studies were identified by searching China National Knowledge Infrastructure (CNKI),Chinese BioMedical Literature Database (CBM),VIP Database for Chinese Technical Periodicals (VIP),Wanfang database,PubMed and Embase.The Meta-analysis was applied with Stata 12.0 software.Subgroup analysis and sensitivity analysis were performed to test the robust of the results.Results A total of 28 studies,including 53 308 residents,were finally included in the review.Meta-analysis revealed the prevalence of health literacy in China to be 16％ (95％CI 15％-16％),and the prevalence of health concepts and knowledge was 25％ (95％CI 25％-26％),and healthy lifestyles and behaviors was 13％ (95％CI 12％-14％),and health skills was 32％ (95％CI 31％-32％).Conclusions The health literacy levels of residents showed a rising trend.There were differences between rural and urban health literacy levels and different regions.Rural residents' health literacy level increased more significantly than that of the city.Due to limited kinds of methods,more scientific and effective methods were needed to evaluate the health literacy.

Investigators selected students who had finished physiology course using the second edition of textbook for long-term medical program.A questionnaire about its content organizations as well as overall compiling condition was designed.Investigators collected the feedback information from the 94 available questionnaires.Meanwhile,some contributive suggestions were provided for the compiling of the whole series of long-term medical program textbooks.

【Objective】 To explore the clinical value of thromboelas-tography, coagulation four items and platelet count in guiding platelet transfusion in critically ill patients. 【Methods】 A total of 188 critically ill patients in Intensive Care Unit of our hospital from January 2020 to January 2022 were selected as subjects, and were divided into study group(n=89) and the control(n=99) according to the presence of bleeding symptoms. T-test was used for comparative analysis between the two groups. Spearman was used to analyze the correlation between TEG, coagulation four items and platelet count, and binary Logistic regression analysis was used to predict the influential factors of bleeding in critically ill patients, ROC curve was used to analyze the guiding value of the above-mentioned indexes for platelet transfusion. 【Results】 1) K and PT values in the study group, above the normal range, were significantly higher than those in the control, while the Angle value, MA value, CI value, FIB value and platelet count were significantly lower than those of the control, among which MA value, CI value and platelet count were below the normal range. 2) TEG, coagulation four items and platelet count were correlated. MA and CI values were positively correlated with platelet count, instead, R and K values were negatively correlated. R value was positively correlated with PT and APTT, CI value, on the contrary, was negatively correlated, K value was positively correlated with PT, while Angle value and MA value were negatively correlated. 3) Binary Logistic regression analysis showed that decreased MA value and decreased platelet count were independent risk factors for predicting bleeding in critically ill patients(P<0.05). 4) ROC curve analysis showed that the areas under ROC curve corresponding to Angle value, MA value, CI value, FIB value and platelet count were 0.866, 0.932, 0.9, 0.838 and 0.987(P<0.05). The sensitivity was highest in platelet count and lowest in FIB. The specificity was highest in MA and lowest in Angle. Compared with the single index, the area under the curve of the combined index(K value, MA value, CI value, PT value and platelet count) was 0.995(P<0.05), Yoden index 0.944, sensitivity 100%, specificity 93.3%, all higher than the individual index. 【Conclusion】 Thromboelas-tography combined with coagulation four items and platelet count can be used to accurately predict the critically ill patients with bleeding risk. To guide clinical platelets transfusion, the combined use of indexes, including K value, MA, CI value, PT and platelet count, is superior to separate use of them as the former showed better sensitivity and specificity, demonstrating a good clinical value.

Objective: To analyze the epidemiological history, clinical manifestations, treatment and the short-term prognosis of 31 cases of 2019 novel coronavirus(2019-nCoV) infection in children from six provinces (autonomous region) in northern China. Methods: A retrospective analysis of the epidemiological history, clinical symptoms, signs, laboratory examinations, chest imaging, treatment and the short-term prognosis of 31 cases of 2019-nCoV was conducted. The patients were diagnosed between January 25th, 2020 and February 21st, 2020 in 21 hospitals in 17 cities of six provinces(autonomous region) of Shaanxi, Gansu, Ningxia, Hebei, Henan and Shandong. Results: The age of the 31 children with 2019-nCoV infection was 7 years and 1 month (6 months -17 years). Nine cases (29%) were imported cases. Other 21 cases (68%) had contact with confirmed infected adults. One case (3%) had contact with asymptomatic returnees from Wuhan. Among the 31 children, 28 patients (90%) were family cluster cases. The clinical types were asymptomatic type in 4 cases (13%), mild type in 13 cases (42%), and common type in 14 cases (45%). No severe or critical type existed. The most common symptom was fever (n=20, 65%), including 1 case of high fever, 9 cases of moderate fever, 10 cases of low fever. Fever lasted from 1 day to 9 days. The fever of fifteen cases lasted for ≤3 d, while in other 5 cases lasted > 3 d. Other symptoms included cough (n=14, 45%), fatigue (n=3, 10%) and diarrhea (n=3, 9%). Pharyngalgia, runny nose, dizziness, headache and vomiting were rare. In the early stage, the total leukocytes count in peripheral blood decreased in 2 cases (6%), the lymphocytes count decreased in 2 cases (6%), and the platelet count increased in 2 cases (6%).Elevation of C-reactive protein (10%, 3/30), erythrocyte sedimentation rate(19%,4/21), procalcitonin(4%,1/28), liver enzyme(22%, 6/27) and muscle enzyme (15%, 4/27) occurred in different proportions. Renal function and blood glucose were normal. There were abnormal chest CT changes in 14 cases, including 9 cases with patchy ground glass opacities and nodules, mostly located in the lower lobe of both lungs near the pleural area. After receiving supportive treatment, the viral nucleic acid turned negative in 25 cases within 7-23 days. Among them, 24 children (77%) recovered and were discharged from hospital. No death occurred. Conclusions In this case series, 2019-nCoV infections in children from six provinces (autonomous region) in northern China are mainly caused by close family contact. Clinical types are asymptomatic, mild and common types. Clinical manifestations and laboratory examination results are nonspecific. Close contact history of epidemiology, nucleic acid detection and chest imaging are important bases for diagnosis. After general treatment, the short-term prognosis is good.
