Objective To evaluate the influence of successful revascularization by percutaneous coronary intervention(PCI)on heart function of patients with heart dysfunction combined with chronic total occlusion(CTO).Methods The clinical data of 272 patients with heart dysfunction combined with CTO were analyzed.The patients were divided into PCI success group(246 cases)and PCI failure group(26 cases)respectively according to the results of PCI.Six months after PCI,the patients underwent cardiac ultrasound examination to compare the heart function between the two groups.Results Cardiac ultrasound examination was successfully performed in 229 patients in PCI success group and 24 patients in PCI failure group at 6 months after PCI.The left ventricular ejection fraction(LVEF)and left ventricular end-diastolic volume index(LVEDVI)showed no significant difference in PCI failure group at 6 months after PCI compared with that before PCI(P＞0.05).In PCI success group,LVEF and LVEDVI were significantly increased at 6 months after PCI compared with that before PCI and compared with that in PCI failure group at 6 months after PCI[(51±5)％ vs.(43±6)％ and(45±2)％,(77±13)ml/m2 vs.(86±12)ml/m2 and(86±10)ml/m2,P＜0.05].The cardiac functional grading in PCI failure group had no significant difference compared with that before PCI(P＞0.05),but in PCI success group it had significant difference compared with that before PCI and compared with that in PCI failure group at 6 months after PCI(P＜0.05).Conclusion Successful revascularization by PCI can improve heart function in patients with heart dysfunction combined with CTO.

Objective To evaluate the relationship between emergence agitation (EA) during recovery from general anesthesia and postoperative cognitive dysfunction (POCD).Methods Two hundred and eighty ASA Ⅰ or Ⅱ patients,aged 18-70 yr,weighing 52-80 kg,undergoing elective surgery,were included.Anesthesia was induced with midazolam,fentanyl,propofol and cisatracurium.The patients were tracheal intubated and mechanically ventilated.Anesthesia was maintained with remifentanil,propofol and cisatracurium.EA was assessed at 15-40 min after extubation by using Post-operative Quality Recovery Scale and the cognitive function was assessed at day 1 before operation and days 1-7 after operation.Patients were divided into POCD or nonPOCD group according to the occurrence of POCD.The general data of patients,preoperative complications and types of surgery were recorded.If there was significant difference between the 2 groups,the factor was analyzed using multi-factor logistic regression to select the risk factor for incidence of POCD.Results The incidence of POCD was 40.7 ％.The results of logistic regression analysis showed that the dangerous degree of the risk factors for POCD in order from high to low were emergence agitation,duration of anesthesia and age.Conclusion EA during recovery from general anesthesia is an independent risk factor for POCD.

Objective: to examine the relationship between emotional states and skin conductance response during lie- detection and to provide evidence for improvement of lie- detection technique. Methods: 38 university students participat- ed in the study. They were provided with antisocial behavior materials that elicited different levels of emotional arousal. Results: Significant difference in skin conductance response was observed with the high emotionality items eliciting the highest skin conductance response. Conclusion: Under a certain level of pressure, individuals’emotional state has direct impact on skin conductance. High emotionality questions are better for detecting lies and honesty than low emotionality questions. In addition to lying, the questions themselves have direct impact on subjects’emotional responses, which in turn lead to skin conductance response. When cues for emotionality are obvious, related events tend to receive greater at- tention by subjects and thus lead to special skin conductance response.

Objective To establish the model of myocardial infarction by ligation of the left anterior descending branch in rats.Method Adult inbred strain Wistar rats were randomly divided into sham group(n=6) and model groups(n=79).Model of myocardial infarction were established by ligation of the left anterior descending branch.The electrocardiogram(ECG),HE staining tissue sections,and heart function of the rats were compared in the two groups.Results Rats in the model group had showed special changes of ST-T and Q wave in ECG,show serious necrosis of myocytes and proliferation of fibrous tissue compared with rats in the sham group.The left ventricular systolic pressure(LVSP),left ventricular develop pressure(LVDP),?dp/dt_(max),heart rate(HR) were significantly decreased in the rats of model group than those of the sham group(P

Objective To investigate the pattern of plasma kisspeptin levels in normal female during various pubertal Tanner stages and the girls with idiopathic central precocious puberty(ICPP) or with premature thelarche(PT), and to evaluate the significance of detecting plasma kisspeptin levels as a new criterion for early differentiation between ICPP and PT.Methods Each study group of normal pubertal females with Tanner stage Ⅰ to Ⅴ comprised 16 to 19 individuals.The levels of plasma kisspeptin were also detected in girls with ICPP(n= 10)or PT(n = 12).The plasma kisspeptin levels were detected by enzyme-linked immunosorbent assay (ELISA).Results The level of kisspeptin was significantly higher in ICPP group than in that of PT group [(1.73±0.23 vs1.43±0.29) ng/ml, P＜0.05].Among the normal pubertal females, the level of kisspeptin decreased gradually from Tanner stage Ⅱ to Tanner stage Ⅴ, being highest in Tanner stage Ⅱ [(1.73±0.22) ag/ml] ,lower in stage Ⅳ and Ⅴ than in stage Ⅰ and Ⅲ (P＜0.01).Conclusions Plasma kisspeptin level was the highest during Tanner stage Ⅱ in normal female pubertal development.It is significant to detect plasma kisspeptin level for the differential diagnosis of ICPP and PT.
