Objective To investigate the role of oxidative stress in type 2 diabetes patients with macrovascular complications. Methods Serum levels of 8-hydroxy-deoxygnan osine (8-OHdG) and hemoglobin Alc (HbAlc) in 32 cases of type 2 diabetic patients with macrovascular complications and 46 cases of patients without complications were determined. 8-OHdG was detected by enzyme linked immu-nosorbent assay (ELISA). Results The level of 8-OHdG (2.93±1.37) ng/mL in type 2 diabetic patients with macrovascular complica-tions was higher than those without complications, whose 8-OHdG level was (2.67±1.30)ng/mL, but the difference was not significant(P>0.05). Compared with all kinds of macrovascular complications in patients, the 8-OHdG levels were increased, but the difference were not significant (P>0.05). Compared with patients without complications, the duration and age of the patients with macrovascular compli-cations also increased significantly (P<0.05), but the HbAlc levels were not statistical difference between them (P>0.05). Spearman regression analysis showed that 8-OHdG level was positively correlated with the duration (r=0.33, P<0.05), while the age and HbAlc level had no obvious correlation (P>0.05). Conclusion The role of oxidative stress may not be the important reason in type 2 diabetes with macrovascular complications, but the duration and age of the patients may be closely related with the disease.

Objective To investigate the clinical value of procalcitonin (PCT) levels in bacteria identification in intensive care unit (ICU) patients with bloodstream infection.Methods There were 540 cases of patients with bloodstream infection in our ICU between December 2007 and December 2013.The PCT levels and bacteria were identified.The application effectiveness of PCT levels in the bacteria identification was studied.Results The G+ bacteria infection rate was 49.63％ (268/540),G-bacteria infection rate was 38.52％ (208/540),and the fungal infection rate was 11.85％ (64/540).The patients of G-bacteria had significant difference with G + bacteria and fungal infection (P ＜ 0.05).The PCT average and positive rate of G-bacteria were significantly higher than G + bacteria and fungi group (P ＜ 0.05),respectively.G+ bacteria and fungi infection did not have significant difference (P ＞ 0.05).When PCT ＞ 2.04 ng/ml,the sensitivity and specificity that applying serum PCT level to identify the between G-and G+ bacteria were 82.18％ and 76.09％,respectively.When PCT ＞3.16 ng/ml,the sensitivity and specificity that applying serum PCT level to identify the between G-and fungus bacteria were 59.42％ and 65.73％,respectively.Conclusions The identification between G-bacteria and G + bacteria,fungi with applying PCT level in bloodstream infections had high accuracy.When the PCT levels was greater than 2.04 ng/ml,the occurrence of G-bacteria was greater risk of infection.The accuracy of PCT level identifying the G + bacteria and fungi was poor.

OBJECTIVETo study therapeutic effects between hook plate fixation and modified Weaver-Dunn surgery for the treatment of acromioclavicular joint dislocation.

METHODSForty patients with fresh acromioclavicular joint dislocations of type III according to Rockwood classification were reviewed. All the patients were divided into two groups: hook plate fixation group and modified surgery group. There were 20 patients in hook plate fixation group, including 13 males and 7 females, with an average age of (37.45 +/- 14.29) years old; 12 patients had injuries in the left and 8 patients had injuries in the right; preoperative Constant-Murley score was 40.75 +/- 10.40. And there were 20 patients in modified surgery group,including 11 males and 9 females, with an average age of (41.65 +/- 14.83) years old; 11 patients had injuries in the left and 9 patients had injuries in the right; preoperative Constant-Murley score was 42.75 +/- 8.18. The Lazzcano standard, Constant-Murley score and imaging changes were used to evaluate shoulder joint function before and after surgery.

RESULTSAll the patients were followed up,and the duration ranged from 7 to 32 months,with an average of 24 months. According to Lazzcano evaluation, 16 patients got an excellent result,3 good and 1 poor in modified surgery group with no re-dislocation, and 1 patient had pain more than middle degree; while in hook plate fixation group, 9 patients got an excellent result, 7 good and 4 poor, 1 patient had re-dislocation, and 3 patients got pain more than middle degree. The therapeutic effects of modified surgery group were better than those of hook plate fixation group. Constant-Murley scores:preoperative 42.75 +/- 8.18 vs 93.40 +/- 4.04 at the latest follow-up in modified surgery group; preoperative 40.75 +/- 10.40 vs postoperative 88.40 +/- 4.81 and 92.05 +/- 4.49 at the latest follow-up in hook plate fixation group. The postoperative scores all improved compared to preoperative scores in two groups. And there was no statistical difference of scores at the latest follow-up between two groups.

CONCLUSIONThe surgery of allograft tendon transplantation combined with anchor fixation to strengthen coracoclavicular ligament, as well as part transposition of acromiocoracoid ligament and resection at the distal part of clavicle may got safety fixation and less postoperative complications compared with hook plate internal fixation.
