Annexin A3（ANXA3）is a member of the membrane associated protein family. It has two subtypes of 36 kDa and 33 kDa. Its gene is located on the fourth chromosome of human. ANXA3, widely expressed in human bone marrow, lung, placenta, prostate and thyroid, is closely related to several biological processes such as exoplasmosis, vascular production, fat cell maturity, and white blood cell migration. Studies have found that ANXA3 is abnormally expressed in various diseases including cancer, cardiovascular disease and inflammation. It can regulate multiple signaling pathways such as JNK, NF-κB, PI3K/AKT, and may become a potential drug target for treatment of related diseases. The structure, functions, the link with diseases and related mechanisms of ANXA3 were summarized in this paper, which could provide reference for ANXA3 related research.

Objective:To establish and internally validate a nomogram model for predicting complicated acute appendicitis (CA).Methods:The clinical data from 663 acute appendicitis patients from the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from October 2015 to October 2022 were retrospectively analyzed. There were 411 males and 252 females, aged ( M (IQR)) 41 (22) years (range: 18 to 84 years). There were 516 cases of CA and 147 cases of uncomplicated acute appendicitis. The minimum absolute contraction and selection operator regression model was used to screen the potential relative factors of CA, and the screened factors were included in the Logistic regression model for multivariate analysis. Software R was used to establish a preoperative CA nomogram prediction model, the receiver operating characteristic curve of the model was drawn, and the value of area under the curve (AUC) was compared to evaluate its identification ability, and the Bootstrap method was used for internal verification. Results:The elderly (age≥60 years) ( OR=2.428, 95% CI: 1.295 to 4.549), abdominal pain time (every rise of 1 hour) ( OR=1.089, 95% CI: 1.072 to 1.107), high fever (body temperature≥39 ℃) ( OR=1.122, 95% CI: 1.078 to 1.168), total bilirubin (every rise of 1 μmol/L) ( OR=2.629, 95% CI: 1.227 to 5.635) were independent relative factors of CA (all P<0.05). The AUC of this model was 0.935 (95% CI: 0.915 to 0.956). After internal verification using the Bootstrap method, the model still had a high discrimination ability (AUC=0.933), and the predicted CA curve was still in good agreement with the actual clinical CA curve. Conclusion:The clinical prediction model based on the elderly (age≥60 years), prolonged abdominal pain time, high fever (body temperature≥39 ℃), and increased total bilirubin can help clinicians effectively identify CA.

Objective:To investigate the characteristic of mild cognitive impairment (MCI) in the adults aged 48 years and over in a coal mine community, and to analyze its associated risk factors.Methods:From July to October 2019, a questionnaire survey for basic information was conducted among 180 middle-aged and elderly adults who met the inclusion criteria in the Datong coal mine community. The cognitive function was evaluated by Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The effects of gender, age, years of education, sleep, living alone, physical exercise, social activities, smoking and drinking status, body mass index and chronic diseases on cognitive level were analyzed by single factor stratification and multiple linear regression.Results:There was no significant difference in the positive rate of MCI screened by MMSE and MoCA in the age groups of 48-<64, 64-<72 and 72-90 (original and corrected P>0.05); The positive rate of MCI in MoCA screening (64.4%, 66.7%, 60.9%) was significantly higher than that in MMSE (35.6%, 45.6%, 28.1%) (all P<0.05); MMSE was positively correlated with MoCA score ( r=0.762, P<0.001). With the increase of age, the scores of memory, execution and visual space detected by MoCA decreased significantly (all P<0.05), while the scores of attention, language and orientation did not change significantly (all P>0.05). Univariate stratification showed that the significant influencing factors of MMSE or MoCA scores were gender, age, years of education and sleep status (all P<0.05). Multiple linear regression analysis showed that gender ( βMMSE=-0.192; βMoCA=-0.140), years of education ( βMMSE=0.209; βMoCA=0.328) and sleep status( βMMSE=-0.162; βMoCA=-0.136) were risk factors affecting MMSE and MoCA scores ( P<0.05). Conclusions:More middle-aged and elderly adults with MCI might be observed in a coal mine community, and the main characteristics of MCI are impaired memory, executive function and visual space. To prevent and reduce the occurrence of dementia, early interventions of MCI should be carried out among the adults with female, old age, low years of education and poor sleep quality.

Objective:To explore the status quo of the readiness of evidence-based nursing practice for the maintenance and removal of children's central venous catheter (CVC) in 6 domestic medical institutions Pediatric Intensive Care Unit (PICU), analyze the obstacles faced by the application of CVC maintenance and removal evidence in PICU, so as to provide basis for formulating reform strategies.Methods:This study was a cross-sectional survey. In December 2019, 169 nurses from PICU of 6 medical institutions in Shanghai, Guangzhou, Shenzhen, Hangzhou, Xiamen and Hefei were selected by convenience sampling for investigation. The General Information Questionnaire and Clinic Readiness to Evidence-based Nursing Assessment (CREBNA) were used to evaluate the readiness of clinical nurses to evidence, organizational environment and promoting factors in the process of evidence-based practice. A total of 169 questionnaires were issued, and 169 valid questionnaires were recovered, with a valid recovery rate of 100%.Results:A total of 169 nurses were investigated in 6 evidence application sites. The total score of the multi center CREBNA was (136.96±15.33), which was 88.36% of the full score. The scores of the three dimensions were as follows: organizational environment (40.31±4.45), evidence dimension (53.43±6.14), and promoting factors (43.22±5.81). Four of the last five items in the score ranking were from the promoting factor, and the low score items in four places were all from the promoting factor.Conclusions:The best practice project of children's CVC maintenance in PICU is feasible. However, there are still some deficiencies in the preparation of various evidence application sites, especially in the promoting factors, which should be constantly improved to further promote and maintain the implementation of change.

Chronic critical illness (CCI) refers to a group of critically ill patients who survive the acute phase of intensive care, but with persistent organ dysfunction, thus entering a chronic period of continuous dependence on life support system, and still need to stay in intensive care unit (ICU) for a long time. Persistent inflammatory response-immunosuppression-catabolic syndrome (PICS) is the main pathophysiological feature of CCI. Three factors interact to form a vicious circle, leading to poor prognosis. Nutritional support therapy is a key link in the comprehensive treatment of CCI. Enteral nutrition (EN) should be started as soon as possible if conditions permit. If EN can not be implemented, temporary or transitional parenteral nutrition (PN) should be used, and EN should be added gradually in time. At the same time, the amount of PN should be gradually reduced. When EN meets more than 60% of patients’ energy and protein requirements, PN can be considered to be discontinued. The main strategies and functions of CCI nutritional support therapy are as follows: strengthening high protein supply to correct negative nitrogen balance and inhibit catabolism, selecting branched chain amino acids (BCAA) to promote anabolism, using immunomodulators (arginine, ω3 polyunsaturated fatty acids) to improve immune suppression and inflammatory response, supplementing micronutrients (vitamins and trace elements) to counteract the decrease in intake and the increase in consumption, and adding probiotics to maintain the intestinal microecological balance, and so on. Reasonable nutritional support therapy not only improve malnutrition of CCI patients, but also help to reduce complications, thus speeding up rehabilitation, improving prognosis, shortening ICU hospitalization time, and even reducing mortality.

Objective To investigate the gestational weight gain and quality of life in women with gestational diabetes mellitus(GDM) who used Free-Style Libre Flash Glucose Monitoring System. Methods From August of 2017 to January of 2019, the GDM patients diagnosed in the Department of Endocrinology in 3 ClassⅢ Grade A hospitals in Guangzhou were selected and divided into the observation group(n=39) and control group(n=43) according to their glucose monitoring willingness. The Free-Style Libre Flash Glucose Monitoring System was used for the observation group(sensor changed every 14 days) combined with the fingertip blood glucose monitor, it was necessary to monitor fingertip blood glucose contrast when hypoglycemia was identified by sensors. Pregnant women at other monitoring points could selectively monitor fasting and postprandial blood glucose. In the control group, after assigned into the group patients only monitored their fingertip blood glucose(at lease 2 times/d, including fasting and 2h postprandial blood glucose). The two groups were all instructed by self-management on diet, exercise etc according to the result of blood glucose monitor, the Wechat management was included to instruct them of the daily life diary recording method. World Health Organization-5 Well-Being Index (WHO-5) was adopted at the beginning of the study and the second week of follow-up to investigate the well-being index score of the patients in the two groups; at the end of pregnancy, the average perinatal blood sugar level, incidence of hypoglycemia events and the eligible rate of weight gain in different BMI patients were recorded. Results At the 2nd week, the score of well-being index in the observation group was higher than that in the control group with statistical significance(P=0.037).There was no statistically significant difference in fasting and 2 h postprandial glucose between the two groups (P＞0.05). There was no significant difference in blood sugar control (fasting and 2 hours after meal) between the two groups (P＞0.05), but the detection rate of hypoglycemia in the group using Free-style Libre glucose monitoring system was higher than that in the control group (P=0.042). By the end of pregnancy, stratified analysis showed that the qualified rate of weight gain in the observation group with BMI between 18.5 and 24.9 kg/m2 before pregnancy was higher than that in the control group with statistical significance(P=0.035). Conclusions The use of Free- Style Libre Flash Glucose Monitoring System in GDM patients makes gestational weight control more reasonable and painless, and improves the well-being index of patients.

Objective To compare the diagnostic value of contrast-enhanced ultrasound (CEUS) and contrast-enhanced helical computed tomography (CECT) for hepatocellular carcinoma (HCC) with liver cirrhosis. Methods Two hundreds and forty-one focal liver lesions in 207 patients with Hepatitis B virus (HBV) cirrhosis were detected with CEUS and CECT, respectively. Pathological results were used asgold standardto compare the two methods. Diagnostic results of the two methods were compared with pathological results. Differences were assessed using the McNemar test, and the Kappa test was used for consistency evaluation. Results (1) For 113 liver lesions that were ≤2 cm, the number of HCC lesions was 63, and the number of benign lesions was 50. There were no significant differences in results of CEUS and CECT compared with that of the gold standard of McNemar test results (P = 0.824, P = 0.082). Consistency of the Kappa test results of CEUS and CECT in comparison with the gold standard was general (Kappa = 0.643, Kappa = 0.421). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of HCC diagnosed by CEUS were higher than those of CECT. The rate of arterial enhancement was better for CEUS [87.30% (55/63)] than that for CECT [69.84%(44/63),χ2=5.704, P=0.017]. (2) For 128 liver lesions that were>2 cm, the number of HCC lesions was 77, and the number of benign lesions was 51. There were no significant differences in the diagnostic results between McNemar test and CEUS and CECT tests (P = 0.481, P = 0.167). Consistency of the Kappa test results of CEUS and CECT and gold standard was general (Kappa = 0.710, Kappa = 0.697). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of HCC were not different between two diagnostic methods. The rate of arterial enhancement was 89.61%(69/77) for CEUS and 85.71%(66/77) for CECT, and there was no significant difference between the two groups (χ2=0.540, P=0.462). Conclusion For HCC≤2 cm, the diagnostic performance of CEUS is better than that of CECT. For HCC>2 cm, the diagnostic performance is similar for the two diagnostic methods.

Posttraumatic stress disorder (PTSD) refers to the sudden, threatening or catastrophic life events leading to delay and long-term persistence of mental disorders. Hippocampus, amygdala, prefrontal cortex and hypothalamus-pituitary-adrenal axis (HPA) may be involved in PTSD, but the exact pathogenesis is not entirely clear. Traditional Chinese Medicine, including Chinese herbs, acupuncture and emotion-thought therapy, are considered as the main methods for PTSD, which may play a role in neuroprotection, adjustment of learn-ing-memory, anti-stress, adjusting HPA, etc.
