The method of under--water weighing was used to measure the body composition of seventeen rhythmicgymnasts and four ordinary women. The average fat percentage was found to be 19. 0% in the gymoasts and26. 4% in the non--gytnnasts. The fat oercentage in the body composition of an athlete is not directly proportional to her body weight.It is inversely proportional to her training level. Therefore, in evaluating the physical condition of an athlete,her fat percentage must be taken into account. An artistic gymnast who is reducing bodyweight shows a negative energy belance of 50. 5% and insuffi-cient intake of protein and vitamins. Reduction of bodyweight should therefore be carried out under medicalsupervision.

Objective To construct and implement theSTARnurse training model, and discuss its application effect and the problems that should be paid attention to, and to provide operational cases and practical basis for nursing clinical education. Methods Through literature review and expert consultation, the framework and content of STAR nurse training model were set up and implemented. The questionnaire survey and semi structured in-depth interviews were conducted among the nurses in the hospital to evaluate the effect of improving the nurses′self-directed learning ability. Results After the implementation of the project, the scores of the three dimensions of self-management, desire for study and self-control were (3.67±0.57), (4.05±0.54), (3.99±0.50) points, which were higher than (3.55±0.49), (3.71± 0.52), (3.53±0.42) points before implementation. The difference was statistically significant (P<0.05 or 0.01). The semi structured in-depth interviews showed that all the nurses believed that STAR nurse training model could promote independent learning and stimulate interest in learning. 14 nurses thought it was beneficial for the nurses to find the problems. Conclusions STAR nurse training model can create a favorable learning environment for nurses, and stimulate the learning motivation. It plays a positive role in improving nurses′ability of self-directed learning.

Objective: To explore the nursing experience of growth hormone provocative test in pediatric clinic. Methods: Five thousand and thirty-six children with short stature or slowing growth received combined simultaneous Levodopa Pyridostigmine stimulation test from June 2008 to October 2018 in the Child Growth Center of the First Affiliated Hospital of SUN Yat-sen University. Comprehensive nursing intervention was conducted to ensure the test carry through successfully before, during and after the test. Results: All children completed the five collections in the 120-minute growth hormone provocative test without cannula obstruction and blurt out. Some (986 out of 5 036 children, 19.58%) had different degrees of adverse reactions including nausea, vomiting, abdominal pain, sweating, salivation, dizziness, pallor, etc., most of which disappeared or alleviated after nursing, except 11 patients (0.22%) needed atropine muscular injection and 3 of whom needed intravenous fluids to release the marked symptoms. Conclusion Combined simultaneous Levodopa Pyridostigmine stimulation test is safe and practicable in pediatric clinics with nursing experience.

Objective To investigate the changes in serum HP and ADMA levels in patients with ACI and the correlation of their levels with recanalization after venous thrombolysis and poor prognosis.Methods A total of 260 ACI patients undergoing venous thrombolysis in our hospital from January 2020 to March 2023 were retrospectively recruited,and were categorized into reper-fusion group(n=196)and non-reperfusion group(n=64)based on the efficacy of thrombolysis.After a 90-day follow-up,they were further divided into good prognosis group(n=159)and poor prognosis group(n=101)according to the results of a modified Rankin scale.Serum levels of HP and ADMA at admission were compared between the two groups.Logistic regression analysis was used to analyze the risk factors for non-reperfusion and poor prognosis in ACI patients.ROC curve analysis was performed to evaluate the predictive value of serum HP and ADMA levels for non-reperfusion and the diagnostic efficiency for poor prognosis in ACI patients.Results The non-reperfusion group exhibited notably elevated serum HP and ADMA levels than the reperfusion group(2.10±0.21 g/Lvs1.29±0.31 g/L,1.68±0.19 μmol/L vs 0.69±0.11 μmol/L,P＜0.01).HP and ADMA were identified as significant risk factors for uncanalization after treatment(P＜0.01).The AUC value of their combination in diagnosing uncanalization after venous thrombolys-is was 0.869(95％CI:0.830-0.908).Furthermore,significantly higher serum levels of HP and ADMA were observed in the poor prognosis group than the good prognosis group(2.27±0.19 g/L vs 1.15±0.34 g/L,1.72±0.21 μmol/L vs 0.64±0.10 μmol/L,P＜0.01).HP and ADMA were also recognized as influencing factors for poor prognosis in 90 d after treatment(P＜0.01).The AUC value was 0.816(95％CI:0.768-0.865)when their combination was used to predict poor prognosis in 90 d after treatment.Conclusion HP and ADMA are highly expressed in the se-rum of ACI patients with failed venous thrombolysis and poor prognosis.Their combined detec-tion can effectively predict both uncanalization and poor prognosis.

Objective To explore the epidemiological status of abnormal glucose metabolism and its influential factors among middle and aged population with hypertension in Chengdu area. Methods In 2008, after adopting the methods of stratified cluster sampling, the authors investigated 4685 subjects of the middle and aged population between the age of 40-79 in Chengdu urban and rural area by checking blood pressure and oral glucose tolerance test (OGTY). Patients with previously known diabetes mellitus (DM) were only asked to perform fasting glucose and to carry out a questionnaire. Comparison of the prevalence rates of abnormal glucose metabolism in hypertensive and non-hypertensive subjects was carried out. The prevalence rates of isolated impaired glucose tolerance (I-IGT) and isolated postprandial hyperglycemia (IPH) among middle and aged subjects with hypertension were acquired and the influential factors of abnormal glucose metabolism among middle and aged subjects with hypertension were analyzed. Results The prevalence rate of abnormal glucose metabolism in the hypertensive subjects was obviously higher than that in the non-hypertensive subjects; without using OGTT, 72.9% of the pre-diubetic and 54. 4% of the new diagnosed DM patients would remain undiagnosed if fasting plasma glucose detection was used alone. Age, diabetic history of first degree relatives ,overweight or obesity were the risk factors for the development of abnormal glucose metabolism among middle and aged male subjects with hypertension in Chengdu area. Exercise training and high education level were the protective factors. Age, diabetic history of first degree relatives,abdominal obesity and hypertriglyceridemia were the risk factors for the development of abnormal glucose metabolism among middle and aged female subjects with hypertension in Chengdu area. Conclusions More than 50% of middle and aged subjects with hypertension in Chengdu area has accompanying abnormal glucose metabolism. OGTT easily discloses the abnormal status and should be a routine procedure in the diagnosis of pre-diabetes or DM in such population. Appropriate exercise, learning diabetes-related knowledge to take reasonable lifestyle, and intervention of metabolic factors such as overweight or obesity are advised. Abdominal obesity and hypertriglyceridemia play important roles in leading to abnormal glucose metabolism among middle and aged population with hypertension.

Objective To investigate the correlation and clinical significance between serum uric acid (SUA) levels and insulin resistance in type 2 diabetes(T2DM) with non-alcoholic fatty liver disease (NAFLD). Methods There were 54 T2DM patients with NAFLD in combined group ,50 cases in simple T2DM group and 37 cases in healthy group.The clinical parameters,SUA and insulin resistance (IR) levels were determined and compared among the three groups.The correlations among NAFLD,SUA levels and IR were analyzed.Results The SUA levels and IR index ( HOMA-IR) of the combined group were higher than those of the other two groups ( SUA:F=9.77,P=0.00;IR:H=122.13,P=0.00).The studies showed that NAFLD was positively correlated with SUA , TG,HOMA-IR(r =0.323,P =0.00;r =0.294,P =0.00;r =0.331,P=0.00).Logistic regression analysis revealed that IR,SUA and TG were the risk factors for T2DM with NAFLD(B=0.852,0.012,0.707).Conclusion The increase of SUA is independent risk factor for T 2DM with NAFLD,so to control SUA and improve insulin sensitivity can help to prevent the development of T 2DM with NAFLD.

Objective:To explore the status quo of self-learning readiness of in-service nurses in self-taught examination and its correlation with general self-efficacy.Methods:Convenience sampling method was conducted with nurses who studied in the self-taught nursing examination of a university from a university in Sichuan Province from March to May 2020. General information questionnaire, Chinese version of Self-regulated Learning Readiness Scale for Nursing Education (SLDRS) and General Self-Efficacy Scale (GSES) were used to investigate the research. SPSS 24.0 was used to analyze the scores, multiple linear stepwise regression analysis was used to analyze the influencing factors, and Pearson correlation analysis was used to analyze the correlation between self-learning readiness and general self-efficacy. A total of 468 questionnaires were collected and 455 were valid.Results:The total scores of 455 nurses were (147.93±18.07) points, and the overall average scores were (3.70±0.45) points. Multiple linear stepwise regression analysis showed that the desire to continue to study for postgraduate students, the times of face-to-face classes in each subject, the preference for nursing major, aimlessness and satisfaction with the forms of assistance were the important influencing factors of autonomous learning readiness ( P<0.05). There is a positive correlation between self-learning readiness and general self-efficacy ( r=0.551, P<0.05). Conclusion:The self-learning readiness of nurses for self-taught examination is at a medium level. Their self-learning ability may be improved by encouraging them to carry out career planning, improving their professional identity and self-efficacy, and choosing teaching methods that are more suitable for in-service staff.

OBJECTIVETo observe the effect of activation of Notch1 signaling pathway by Notch intracellular domain (NICD) plasmid transfection on pancreatic cancer cell proliferation and explore the underlying mechanism.

METHODSThe transfection rates were observed under microscope with fluorescence stimulation, and mRNA expression levels of Hes1 were detected by real-time PCR. Cell proliferation changes were evaluated by CCK-8 after NICD and control plasmid transfection in pancreatic cancer cells. Caspase 3 activity was examined using a caspase 3 detection kit.

RESULTSThe transfection rates of NICD plasmid were up to 80% by fluorescence stimulation observation. Hes1 expression was significantly increased after NICD plasmid transfection, suggesting the activation of Notch1 signaling pathway. NICD plasmid transfection significantly promoted cancer cell proliferation compared to control plasmid transfeciton. The activities of caspase 3 were obviously decreased after NICD plasmid transfection in 3 pancreatic cancer cell lines.

CONCLUSIONActivation of Notch1 signaling pathway by NICD plasmid transfection can promote the proliferation of pancreatic cancer cells by inhibiting the apoptosis pathway.
