ABSTRACT
Objective@#The study aimed to explore the relationship between childhood maltreatment (CM) and the Big Five personality traits of middle school students, so as to provide scientific evidence for promoting the healthy development of middle school students personality.@*Methods@#A total of 5 724 middle school students from Xuancheng, Hefei and Huaibei of Anhui Province were selected by using a multi stage stratified cluster sampling method to conduct a questionnaire survey, including demographic characteristics, CM experience and Big Five personality traits. Linear regression analysis and canonical correlation analysis were used to explore the associations between CM and the Big Five personality traits.@*Results@#Physical abuse, emotional abuse, sexual abuse, physical neglect, and emotional neglect of middle school students were significantly associated with conscientiousness ( β = -1.71 --2.55) and neuroticism ( β =1.93-3.87) personality traits( P <0.05). Except physical abuse, all other types of CM were significantly associated with extraversion ( β =-1.04--2.32) and agreeableness ( β =-1.07--1.37) personality traits( P <0.05), and only sexual abuse was associated with openness personality trait( β=-0.70, P <0.05). Except for openness personality trait, the relationship between the number of CM experience and the personality traits of middle school students was statistically significant; there was a dose response relationship between the number of CM experiences and the scores of personality traits each dimension( P < 0.05). In the canonical correlation analysis, the canonical correlation coefficient was -0.375( P <0.05). CM experiences were mainly reflected by emotional abuse, emotional neglect and physical neglect (canonical load coefficient was 0.556-0.951). The Big Five personality traits were mainly reflected by neuroticism, conscientiousness and extraversion (canonical load coefficient was -0.702 -0.639).@*Conclusion@#There is a correlation between CM and the personality traits of middle school students, and prevention of CM is of great significance for promoting the healthy development of middle school students personality.
ABSTRACT
Objective To compare and discuss the clinical application effect of the end-to-end anastomosis of pancreatic and intestinal anastomosis,binding type of pancreatic and intestinal anastomosis,end-to side pancreatic duct anastomosis and modified pancreatic duct jejunum anastomosis.Methods Collected pancreatoduodenectomy in 95 cases,the end-to-end pancreatico duodenal sleeve type anastomosis in 23 cases,binding type pancreatic enteric anastomosis in 18 cases,end to side pancreaticojejunostomy anastomosis in 28 cases,improvement of the pancreatic duct jejunum end to side anastomosis in 26 cases,compared with four groups of patients with pancreatic enteric anastomosis time and postoperative complications.Results Anastomosis time:A group (34.0 ± 4.6) min,B group (31.0±5.8) min,C group (32.0 ±6.3) min,D group (14.0 ±4.2) min(P=0.037,P＜0.05).And the incidence rate of postoperative pancreatic fistula,bile leakage,abdominal cavity or digestive tract bleeding had no significant difference (P ＞ 0.05).Improvement of the pancreatic tube jejunum end to side coincident with a low incidence of pancreatic fistula,but different pancreatic enteric anastomosis way pancreatic fistula rate difference was not statistically significant,improvement of the pancreatic duct and jejunum mucosa end side group pancreatic enteric anastomosis anastomosis time significantly shorter in the three groups,the difference was statistically significant (P ＜ 0.05).Conclusion Improvement of pancreatic duct jejunum end to side anastomosis with short operation time,low incidence of pancreatic fistula,and the operation is simple and practical,safe.
ABSTRACT
Objective To investigate the correlation between helicobacter pylori (H.pylori) infection with gastric muco?sa pathologic changes in chronic gastritis. Methods A total of 250 patients with chronic gastritis who came to Tianjin Union Medicine Center from November 2011 to March 2013 were collected in this study. Electronic gastroscope examina?tions, pathology and Urea-14C breath tests were performed in patients. There were 153 cases with chronic atrophic gastritis (CAG group), and 97 cases without chronic atrophic gastritis (non-CAG group). The positive rate of H.pylori was compared between two groups. At the same time the positive rate of H.pylori was compared between different parts of CAG patients. The positive rates of H.pylori were compared between different pathologic features of chronic gastritis (active degree, the de?gree of inflammation, atrophy and intestinal classification). Results The positive rate of H.pylori was higher in CAG pa?tients than that of non-CAG patients (70.6%vs 35%,χ2=30.552). The positive rate of H.pylori was higher in antral and cor?pus atrophy of CAG group than that of antral atrophy (82.6%vs 65.4%,χ2=4.578). With the aggravating activity of gastritis, the inflammation, chronic gastritis, atrophy and intestinal classification, the positive rate of H.pylori was increased (χ2=200.643, 206.715, 73.286, 218.432). Conclusion H.pylori infection is related with chronic gastritis, chronic atrophic gas?tritis. And antral and corpus atrophy CAG is closely related with H.pylori infection.
