OBJECTIVETo study the influence of estradiol on histomorphology of skin flaps with ischemia reperfusion injury.
METHODS48 adult male Wistar rats aged 12-14 weeks old, were randomly divided into control group (group I), ischemia-reperfusion group (group II), saline group (group III), estradiol group (group IV). Superficial epigastric artery axial flap, 3 cm x 6 cm in size, was made in the left lower quadrant abdominal of each rat. Flap model with ischemia-reperfusion injury was established by using the nondestructive micro vascular clamp to clamp the superficial epigastric artery. The general condition of the flap was observed after operation. At 7 days after operation, the survival rate of the flap was detected, the flaps were harvested to receive histology and ultrastructural observation. The neutrophils level of the superficial epigastric vein were tested.
RESULTS7 days after operation, the survival rate of the flap in group IV was significantly higher than that in group II, III (P < 0.05). The neutrophils level in group IV was lower than that in group II, III (P < 0.05). The histological observation showed that the degree of tissue swelling and inflammatory exudation in group IV was more slight than that in group II, III. Presence of high neutrophils density were observed in group II, III, while slight inflammation and necrosis were observed in group IV. In group I, collagen fibers in flap are regularly arranged with no significant necrosis. Oganelles structure disappeared and apoptotic bodies were shown in group II and group III, even the lysosome could be seen in the cell. Collagen fibers in flap are regularly arranged with slight swelling and no obvious ultrastructural necrocytosis was seen in the cell of group IV.
CONCLUSIONThe estradiol can significantly increase flap survival rate by inhibiting neutrophils infiltration and improving the pathological changes of organization structure in flap.

Objective To investigate influencing factors of perioperative myocardial injury in patients undergone percutaneous coronary intervention (PCI). Methods Ninty one patients with coronary heart disease (including stable angina and unstable angina) underwent PCI, the perioperative myocardial injury incidence were observed prospectively by monitoring the preoperative and postoperative high sensitivity troponin protein levels to investigate the influencing factors of perioperative myocardial injury by Logistic regression analysis. Results There were no statistically significance in perioperative myocardial injury incidence (62.5%vs 68.7%, P=0.618) and perioperative myocardial infarction incidence (29.2%vs 20.9%, P=0.411) between stable angina and unstable angina groups . These factors of perioperative myocardial injury in patients undergone PCI by Logistic regression analysis were analysed, and we found that the influencing factors were the application loading dose rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels and total stent length. Conclusion Application loading dose of rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels are related to perioperative myocardial injury reduction, whereas the total length of the stent is associated with an increased occurrence of perioperative myocardial injury.

Objective To investigate the effect of baseline Left-ventricular ejection fraction (LVEF) on the cardiac resynchronization therapy (CRT). Methods A retrospective analysis of patients with heart failure was performed. Fifty-four patients [aged (59.73 ± 11.61)years, 31 males, 23 females] who underwent CRT/CRTD were divided into 2 groups according to LVEF ( group A, LVEF≤ 35%; group B, LVEF > 35% ). NYHA class, LVEF,CRT respond rates and medical adverse event (MAE) due to worsening heart failure were detected at 3 and 12 months post-surgery. Results The score of NYHA class changing wasn′t different between these two group. Compared to group B, LVEF was markedly increased (5.08 ± 2.81)% vs (2.45 ± 1.80)%, P < 0.05;(5.38 ± 2.92)% vs (2.39 ± 3.53)%, P < 0.05)at 3 and 12 months post-surgery. Similarly, group A owned high CRT response rates(66.1% vs 33.9%, P < 0.05; 81.25% vs 47.83%, P < 0.05) at the both two time points. At 12 months post-surgery , LVED decreased and the MAE was similar in all groups. Conclusion Patients with EF≤ 35% have more increases in LVEF and own high CRT response rates post-CRT.

OBJECTIVE:To discuss the countermeasure on the quality improvement of the drug clinical trials in our hospital based on the discovery of key links of the quality of clinical trials. METHODS:Quality results of 14 drug clinical trials in 10 ma-jors from the drug clinical trial institute in our hospital in 2014 were investigated. Referring to the grading and classifying methods of the inspection problems in European Medicines Agency,the key links of occurring problems were analyzed,and the effects of interventions for key links were evaluated. RESULTS:In 2014,totally 125 important and general problems were found,in which, the numbers of problems occurred in case report form filling,informed consent of subjects,enrolling and screening of subjects,in-vestigational products management accounted for 79.20%. The above 4 links were the key links affecting quality of drug clinical tri-als. According to strengthening the training about relevant knowledge of the researchers,improving system and standard operation procedures management,enhancing link quality control,introducing project clinical research coordinator,developing centralized drug management and other interventions,the total numbers of found important and general problems in 2015 and 2016 were 68 and 59,respectively. Compared with 2014,the differences were statistically significant(P<0.05). The numbers of found important problems in 2015 and 2016 were 7 and 4,respectively. Compared with 2014(4 important problems),the differences were not sta-tistically significant (P>0.05). There were no severe problems during 2014-2016. After interventions,numbers of occurring prob-lems in majors with less complex drug clinical trial had obviously declined in 2016. Compared with 2014,the differences were sta-tistically significant (P<0.05). While the major with relatively high complexity of drug clinical trial had no obvious decline in 2016. Compared with 2014,the differences were not statistically significant(P>0.05). CONCLUSIONS:Controlling the key links in drug clinical trial process can obviously reduce the occurrence of general problems while has little effect on the occurrence of im-portant problems. It is different for different majors in undertaking drug clinical trial projects,so as the links and degree of occur-ring problems. It should be distinguished in quality control checking.
