Objective To investigate the feasibility and applicability of free airbags,free fixed totally extraperitoneal laparoscopic inguinal hernia repair (TEP) treatment of inguinal hernia.Methods In Baotou Medical College,Department of General Surgery,the First Affiliated Hospital,the 40 cases of patients confirmed with inguinal hernia surgery were choosed from Jan.2010 to Dec.2012 as the observed object,depending on the surgical methods.Divided the cases into the TEP group and the open surgery group to observe statistics including postoperative pain,extent of gastrointestinal function recovery time,the time of bedside movement,the number of days of hospitalization,the incidence of postoperative complications,hospital fees indicators.Results The operation time of TEP group was about 20 minutes longer than the open group and the difference was statistically significant (P ＜ 0.05).Compared with the open group,TEP group' s postoperative pain was milder,postoperative feeding time,the time of bedside movement and postoperative exhaust time were earlier,hospital stays were shoter,incidence of postoperative complications was lower,the differences were statistically significant (P ＜ 0.05).The difference was not statistically significant in hospital costs(P ＞ 0.05).Conclusion TEP inguinal hernia greater advantages compared with traditional open surgery,may be appropriate to carry out in my area.

OBJECTIVE:To establish a method for the content determination of saccharide in polysaccharides containing galact-uronic acid based on phenol-sulfuric acid method combined with correction factor method. METHODS:The determination condi-tion of phenol-sulfuric acid was optimized. A series of standard curves were drawn with glacturonic aid-glucose mixed control with different mass ratio. The content of saccharide in Codonopsis pilosula polysaccharides CPP1b samples containing galacturonic acid was determined. According to regression equation of galacturonic acid-glucose ratio of 0-100%,the correction factor was calculated by using C. pilosula polysaccharides CPP1b as the reference polysaccharide,and the results of content determination of saccharide were corrected. The rationality of this method was verified by using mixed monosaccharide control with same composition as C. pi-losula polysaccharides CPP1b. RESULTS:The correction factor of C. pilosula polysaccharide CPP1b to glucose was 3.33;in vali-dation test,the content of saccharide in mixed monosaccharide control with same composition as C. pilosula polysaccharides CPP1b was 103.47%. RSDs of precision and stability tests was <1%. The recoveries ranged 93.52%-107.35%(RSD=5.09%,n=6). CONCLUSIONS:The established method can accurately determine the content of saccharide in C. pilosula polysaccharides CPP1b containing galacturonic acid.

ObjectiveTo explore the relationship among the aggressive behavior,hostile attribution bias and childhood trauma in schizophrenic patients.Methods 135 schizophrenic patients were tested with Modified Overt Aggression Scale (MOAS),the Chinese-version of the Ambiguous Intentions Hostility Questionnaire (AIHQ-C) and Childhood Trauma Questionnaire (CTQ).According to the score of the MOAS,the patients were divided into the aggressive group ( n =58 ) and the non-aggressive group ( n =77 ).The hostile attribution bias and the childhood trauma were compared between the two groups,and correlation and hierarchical regression analysis were used to investigate the relationships of the variables.ResultsCompared with the non-aggressive patients,the aggressive patients had significantly higher AIHQ-C total hostility bias score (6.27 ± 1.20 vs 5.90 ± 0.97,P ＜0.05 ),total blame bias score (8.04 ± 1.97 vs 6.91 ± 2.10,P ＜ 0.01 ) and total aggression bias score ( 6.17 ±1.02 vs 5.59 ± 1.04,P ＜ 0.01 ).Correlation analysis showed that the MOAS score,AIHQ scores and the total score of CTQ were significantly positively correlated with each other ( r =0.171 ～ 0.350,P ＜ 0.05 ～0.01 ).Regression analysis indicated the hostile attribution bias directly predicted the aggressive behavior( β =0.342,P ＜0.05) and completely mediated the relationship between the childhood trauma and the aggressive behavior.ConclusionThe aggressive behavior in schizophrenic patients is associated with the experience of childhood trauma and the attribution style.The childhood trauma indirectly influences the aggressive behavior by the mediating of the hostile attribution bias.
