Objective:To comparatively analyze the changes regulation of death attitude and death education needs for undergraduate nursing students in different grades.Methods:From March to June in 2019, 766 undergraduate nursing students from Batch 2015 to Batch 2018 of a medical college were collected in cluster sampling. The investigation was conducted by using the scale of Death Attitude Profile-revised in Chinese version and the scale of death education needs. SPSS 22.0 was used for statistical analysis, LSD test for measurement data, and chi-square test for counting data.Results:There were increasing trends of scores from freshman to junior in dimensions of fear of death, approach-oriented death acceptance and escape-oriented death acceptance ( P < 0.05), and the scores decreased in senior, but without statistical difference compared with junior ( P > 0.05). In neutral death acceptance dimension, the score decreased significantly in the second year ( P = 0.001), and then returned back to the original level in the fourth year. No significantly statistical difference was found in scores of different grades in death escape dimension ( P = 0.038). The score of death education need in the fourth year was the highest ( P < 0.05) and was positively correlated with the score of neutral death acceptance dimension ( P = 0.007). Conclusion:With the increase of school year, nursing students' positive attitude for death demonstrates positive trend, while the level of negative attitude of death are becoming balanced. The fourth year is suggested to be the right time to conduct death education immediately.

Objective To study the effect of chemotherapy on function of islet βcells in patients with breast cancer . Methods One hundred and fifty-six patients with breast cancer who had not received chemotherapy were enrolled from Sep 2012 to Aug 2013 at Chongqing Cancer Institute .One hundred and twenty-three cases completed 2 cycles of chemotherapy;one hundred and twelve cases completed 4 cycles;and, eighty-six cases completed 8 cycles.Height, weight, waist circum-ference(WC), hip circumference(HC) and blood pressure of each patient were measured .Waist-high ratio calculation (WHtR),waist-hip ratio(WHR) and body mass index(BMI) were calculated.All subjects underwent 75 g oral glucose tolerance test(OGTT)and insulin release test before chemotherapy,2 cycles,4 cycles and 8 cycles of chemotherapy, respec-tively.Besides, homeostasis model assessment of insulin resistance index ( HOMA-IR), Matsuda index and pancreatic βcells HOME(HOME-β) were calculated.Results Fasting blood glucose before chemotherapy and after 2 cycles, 4 cycles and 8 cycles of chemotherapy was (4.84 ±0.56), (4.78 ±0.61), (5.02 ±0.56) and (5.96 ±0.52) mmol/L, respec-tively.After therapy, the change in fasting blood glucose after 2 cycles and 4 cycles of chemotherapy was not statistically significant(P>0.05), but was significantly higher after 8 cycles than before therapy(P<0.05).2 h blood glucose before chemotherapy and after 2 cycles, 4 cycles and 8 cycles of chemotherapy was (5.43 ±0.50), (5.66 ±0.58), (8.30 ± 0.66) and (9.65 ±0.80) mmol/L, respectively.With chemotherapy treatment increased , the HOME-IR increased gradu-ally and the sharpest one was after 8 cycles, Matsuda index decreased gradually and the biggest drop was after 4 cycles,and HOME-βdecreased gradually after a transient increase .Conclusion Chemotherapy for breast cancer patients may lead to insulin resistance , pancreatic βcell function decline and the emergence of abnormal glucose tolerance .Four cycles of chemotherapy shoucd be followed by hypoglycemic drugs .

Objective To observe the effects of Jianpi Yangxue Qufeng Formula (JPYXQF) on the AQP3 in mice with chronic eczema, and explore mechanism of action. Methods Fifty healthy male mice were randomly divided into 5 groups, namely normal group, model group, positive medicine group and JPYXQF high and low dose groups. Low-dose DNCB and Sennae Fominm were used to establish mice models of chronic eczema with spleen deficiency. JPYXQF groups were treated by JPYXQF for gavage, while the positive medicine group was treated by levocetirizine hydrochloride for gavage. The expression of AQP3 in mice skin tissue was detected by immunohistochemical method. At the same time, the pathological changes of skin were observed. Results The pathology of mice skin lesion showed that JPYXQF has certain recovery effects on the inflammation injury of skin lesion. Compared with the normal group, expression of AQP3 over expressed in model group. Compared with the model group, the expression of AQP3 in all treatment groups significantly decreased, and the staining intensity decreased. In the model group, the average optical density of AQP3 was significantly higher than that in the normal group (P<0.01). Compared with the model group, the treatment groups can reduce the expression of AQP3 in mice skin tissues (P<0.05). Conclusion JPYXQF can reduce the over expression of AQP3 in skin lesion, which is probably its mechanism for the treatment of chronic eczema.

267 newly-diagnosed patients with type 2 diabetes were divided into normoalbuminuria group [group N-UAlb, urinary albumin to creatinine ratio (UACR)<30 mg/g, n=103], microalbuminuria group(group M-UAlb, UACR 30~300 mg/g, n=88 ) , and macroalbuminuria group ( group L-UAlb, UACR>300 mg/g, n=76). The control group(group NC) consisted of 114 healthy individuals. Serum betatrophin, adiponectin(APN), and interleukin-1β( IL-1β) levels were determined with ELISA methods and the parameters of body mass index (BMI), estimated glomerular filtration rate(eGFR), HbA1C, fasting plasma glucose(FPG), OGTT 2h plasma glucose(2hPG), fasting insulin(FINS), OGTT 2h postprandial insulin(2hPINS), fasting C-peptide(FCP), homeostasis model assessment insulin resistant index(HOMA-IR), and blood lipid were collected. Compared with group NC, the serum betatrophin levels in patients with type 2 diabetes were obviously increased. In patients with type 2 diabetes, betatrophin levels increased along with the increase of UACR and there were significant differences in betatrophin among the three groups(P<0. 01). Betatrophin positively correlated with UACR, HbA1C, FPG, 2hPG, FINS, 2hPINS, HOMA-IR, TC, LDL-C, and TG( r were 0. 785, 0. 225, 0. 136, 0. 241, 0. 386, 0. 223, 0. 411, 0.216,0.193,and0.298,allP<0.05),and betatrophin were also positively correlated with APN and IL-1β(rwere 0. 643 and 0. 710, both P<0. 01). Stepwise multiple regression analysis showed that UACR, HbA1C, FINS, and TG were independent relevant factors affecting betatrophin levels.

Objective To investigate the effect of visceral fat area (VFA) on perioperative related indi-cators and short-term prognosis of patients with colorectal cancer (CRC).Methods Clinical data of 102 pa-tients who underwent laparoscopic radical surgery for CRC in the First Affiliated Hospital of Baotou Medical College from September 2020 to August 2023 were retrospectively analyzed.All patients underwent preopera-tive abdominal CT examination,and the transverse CT images at the level of the third lumbar vertebra (L3) were selected.VFA was measured using Slice-O-Matic software,and patients were divided into the high VFA group (VFA≥100 cm2) and the low VFA group (VFA<100 cm2) based on the measurement results.Clinical data,patho-logical data,surgical data,postoperative complications,and perioperative coagulation and inflammation indicators were collected.Results Compared with the low VFA group,the high VFA group had higher BMI,longer hospital stay,greater intraoperative blood loss,and fewer lymph node dissections (P<0.05).The WBC and PCT lev-els before and after surgery in the high VFA group were higher than those in the low VFA group (P<0.05). Compared with preoperative levels,WBC,C-reactive protein (CRP),PCT,plasma prothrombin time (PT), plasma fibrinogen (FIB),and international standardized ratio (INR) increased and PLT decreased in both groups after surgery,the differences were statistically significance (P<0.05);Compared with preoperative conditions,the activated partial prothrombin time (APTT) in the high VFA group and the thrombin time (TT) decreased in the low VFA group decreased after surgery,the differences were statistically significant (P<0.05).The total incidence of postoperative complications (21.2％) and the incidence of incision compli-cations (15.4％) in the high VFA group were higher than that in the low VFA group (4.0％,2.0％),the differences were statistically significant (P<0.05).Conclusion Colorectal cancer patients with high VFA during the perioperative period exhibit higher levels of inflammation indicators and poorer prognosis.

Objective:To investigate how medical students process Western medicine(WM)terms vs.traditional Chinese medicine(TCM)terms and how this is impacted by analogical priming from the perspective of cognitive neuroscience.Methods:The experiments were designed as a 2(TCM terms vs.WM terms)x 2(correct terms vs.incorrect terms)x 2(analogical priming task vs.non-priming task)scheme.A total of 26 medical stu-dents completed a non-priming judgment task and an analogical priming judgment task on medical terms.During the tasks,the participants were asked to make correct/incorrect judgments on WM terms and TCM terms,and their behavioral data and event-related potentials(ERPs)were recorded.Results:Behaviorally,the response speed and accuracy of WM terms were higher than those of TCM terms(both P＜.001),indicating a prominent concreteness effect.Analogical priming shortened the response time to medical terms(P＜.001),and the response time to TCM terms was shortened more significantly(P=.001).For ERPs,WM terms induced a larger P200(an early positive ERP component),a smaller N400(a negative ERP component),and a higher late positive ERP component,indicating supe-riority of attention adjustment,smaller-scale semantic activation,and a higher cost of late semantic analysis and integration.However,the analogical priming eliminated the difference between WM and TCM terms in P200 and N400 while maintaining it in the LPC.This suggests that WM terms are sensitive to analogical attention adjustment,and TCM terms are susceptible to analogical semantic integration.Conclusion:Our findings suggest that WM and TCM disease behavior terms may initially differ in concreteness or the use of a verbal-linguistic system.Analogy is more conducive to understanding TCM terms.This research provides important neuroscientific evidence of the difference in thinking between TCM and WM.
