Objective To investigate the effect of quantifying health education on nurse teaching in cardiovascular department. Methods Totally 98 nursing college students practicing in cardio-vascular department were randomly divided into experimental group and control group . Method of quantifying health education was employed in experiment group while traditional education was used in control group;all patients were guided by health education. After the internship, two ques-tionnaires were used separately to evaluate the health education effects on nurse students and patients. SPSS 17.0 software was used for statistical processing. The measurement data were expressed as x±s; The mean between the groups was compared using t test; the enumeration data between the groups were com-pared using字2 test, the ranked data were compared using rank sum test. α=0.05 was taken as inspec-tion level. Results The health education cognitive scores were higher in experimental group than in control group (P<0.05). The health education ability scores, theoretic test scores, and operation test scores were higher in experimental group than in control group, with statistical differences (t=3.20, 2.10, 2.87; P=0.001, 0.032, 0.004). There were statistical differences in patients' cognition after receiving health education. (Z=13.435, 14.290, 12.901, 12.466, 12.168, 11.350; all P=0.000). Conclusions Quantification of health education can improve health education cognition and ability of nursing students in cardiovascular department, enhance the ef-fectiveness of clinical practice, and help patients master knowledge of health education.

Objective To investigate characteristics of deceleration capacity (DC) and Tp-e/QT value in different age groups of patients with diabetic autonomic neuropathy, and to analyze their influencing factors. Methods A total of 487 subjects were enrolled in this study, and divided into three groups:patients with diabetic autonomic neuropathy (DM+CAN group,n=287), normal glucose tolerance patients with diabetic autonomic neuropathy (CAN group,n=130) and healthy controls (NC group,n=150).Then the DM+CAN group were further divided into three subgroups according to age tertiles:the lowest tertile group (35.0~47.2 years old,n=91),the middle tertile group (47.3~59.6 years old,n=116)and the highest tertile group (59.7~72.0 years old,n=80).All subjects were underwent 24-hour dynamic electrocardiogram recordings.DC and Tp-e/QT values were calculated,and then the correlation between DC and Tp-e/QT with other indicators was analyzed. Results The levels of WC,SBP,BMI,FPG,HbA1c,FIns and HOMA-IR were higher in DM+CAN group than in CAN group and in NC group (P<0.05 or P<0.01).DC increased and Tp-e/QT decreased from DM+CAN group,CAN group to NC group,and the pairwise comparisons were statistically significant (P<0.05 or P<0.01).DM duration,WC,FPG,FIns,HbA1c,HOMA-IR,hypertension and CHD ratio were higher in the highest tertile group and middle tertile group than in the lowest tertile group (P<0.05 or P<0.01).DM duration and FIns were higher in the highest tertile group than in middle tertile group (P<0.05 or P<0.01).RHR and AHR were lower in the highest tertile group than in the lowest tertile group (P<0.05),and there were no statistical significant difference between the middle tertile group and the lowest tertile group (P>0.05).DC increased [(2.90±0.47) vs (4.22±0.41) vs (4.97±0.35) ms],and the Tp-e/QT decreased [(0.23±0.05) vs (0.18±0.03) vs (0.12±0.02)] from the highest tertile group to the lowest tertile group,(P<0.05 or P<0.01),and the pairwise comparisons were statistically significant (P<0.05 or P<0.01).Multiple stepwise regression analysis showed that age,DM duration,WC,FPG,HbA1c,complicated with hypertension and coronary heart disease (CHD) were risk factors for DC and Tp-e/QT values (P<0.05). Conclusion Together with the increased age,DC level is reduced and Tp-e/QT value increased in patients with diabetic autonomic neuropathy.Dynamic electrocardiogram should be considered in patients with advanced age,long DM duration,high level of WC,FPG,HbA1c,and complicated with hypertension and CHD,in order to prevent the occurrence of cardiovascular events effectively.

With the rapid development of general anesthesia technology and the occurrence of new types of inhalation and intravenous anesthetics,safety and comfort requirements of general anesthesia become increas-ingly higher. Therefore,emergence agitation and its adverse consequences gradually receive more and more atten-tion . Thus the etiology and prevention of emergence agitation is an important issue in pediatric anesthesia at pres-ent. In recent years, some achievement has been made in emergence agitation following general anesthesia in children. This article will summarize the related factors,possible mechanisms and prevention strategics of pediat-ric emergence agitation.

Objective To investigate whether intranasal dexmedetomidine prevents the emergency delirium after sevoflurane-based anesthesia (ASA) in children.Methods Ninety children (ASA I,2 to 7years) undergoing elective tonsillectomy with or without adenoidectomy,were randomly divided into group D1 (intranasal dexmedemidine 1.0 μg/kg),group D2 (intranasal dexmedemidine 0.5 μg/kg),and group NS (intranasal normal saline).Anesthesia was induced with sevoflurane (30 min after intranasal administration) and maintained with sevoflurane in 50/50％ O2/N2O.Heart rate (HR),blood pressure (BP),and hemoglobin oxygen saturation (SpO2) were monitored before intranasal administration to 2 hours after extubation.Time of operation and extubation were recorded.Pediatric anesthesia emergence delirium (PAED) scale,Modified Children's Hospital of Eastern Ontario Pain Scale (m-CHEOPS) Pain scale and the adverse effects were observed.Results The PAED scales of group D1 and Group D2 were significantly lower than group NS.No significant differences were found in hemodynamic and respiratory variables,pain scale,time of extubation and adverse effects among three groups.Conclusions Intranasal dexmedetomidine decreased the severity of emergence delirium after sevoflurane-based anesthesia in children without prolonging the time to extubate and affect hemodynamics and respiratory variables.

Objective To investigate the dermoscopic features of palmoplantar melanocytic lesions.Methods The dermoscopic images of palmoplantar melanocytic lesions that underwent examination in the Department of Dermatology in Peking University First Hospital from September 2009 to October 2011,were retrospectively analyzed.Results Totally,155 benign acral melanocytic lesions in 121 patients and 23 acral melanomas in 22 patients were analysed in this study.Among the benign acral melanocytic lesions,the parallel furrow pattern and its variations (34.2％) were the most common,followed by the fibrillar pattern (22.6％).Two benign lesions (1.3％) showed a parallel ridge pattern.Of 23 melanoma lesions,12 (52.2％) exhibited parallel ridge pattern,and 14 (60.9％) showed irregular diffuse pigmentation that was present in all of the invasive melanoma lesions.The fibrillar pattern,as a common benign acral dermoscopic pattern,was also present in 39.1％ of melanoma specimens.Conclusions Dermoscopy is valuable to some extent in the differential diagnosis of benign melanocytic nevi and malignant melanoma in palmoplantar region,and may facilitate the secreening for early melanoma.

OBJECTIVE To evaluate the antibacterial activities of cefoperazone combined with sulbactam against Gram negative bacteria,and compare with other antimicrobial agents.METHODS The antibacterial activities of 10 frequently used antibiotics against 1 670 strains of clinical isolated Gram negative bacteria were studied by using agar dilution methods according to the NCCLS 2002.RESULTS The results showed imipenem was the most active tested against Enterobacteriaceae such as Escherichia coli and Klebsiella pneumoniae,followed by cefoperazone-(sulbactam),which had similar activities as imipenem against the non-fermentative strains such as Pseudononas aeruginosa,and Acinetobacter spp,but cefoperazone-(sulbactam) had higher susceptibility to imipenem-(resistant) Stenotrophomonas maltophilia.CONCLUSIONS Cefoperazone-sulbactam has good and broad spectrum(antibacterial) activities especially against Gram negative(bacteria,) and is expected to have a bright prospect in the treatment of severe hospital infections induced by Gram negative bacteria.

The perinatal risk factors of transient hypothyroxinemia(TH) in premature very-low-birth-weight infants (VLBWI) was investigated by longitudinally assessing thyroid hormones concentrations during their early life after birth and analyzing the relationship to perinatal factors. The serum TT4 concentration on day 7 was (61.03±24.19)nmol/L and the incidence of TH was 12. 05% (n= 10). Pulmonary surfactant support ( OR = 14.25, 95% CI2. 61-70. 07), ventilation support ( OR = 13. 76,95% CI 2. 55-68. 05) , dopamine support ( OR = 9.45, 95% CI 2. 26-39. 5 ) , and gestational age less than 30 weeks ( OR = 5. 78,95% CI 1. 36-24. 49) were perinatal risk factors for TH of premature VLBWI.

Objective To investigate the effects of inhalation of isoflurane at different time points on hypoxic-ischemic brain injury in neonatal rats.Methods One hundred and eighty 7-day-old Sprague-Dawley rats,weighing 12-16 g,were randomly divided into 6 groups (n =30 each):sham operation group (group Ⅰ),cerebral hypoxia/ischemia (H/I) group (group Ⅱ),and inhalation of isoflurane at different time point groups (groups Ⅲ-Ⅵ).Brain ischemia was induced by double ligation of left common carotid artery followed by inhalation of 8 ％ O2 + 92 ％ N2 for 2 h at 37 ℃.In groups Ⅲ,Ⅳ,Ⅴ and Ⅵ 1.5 ％ isoflurane was inhaled for 30 min starting from 0,3,6,12 h after H/I respectively,while the rats were exposed to 30％ O2 and 70％ N2 only in groups Ⅰ and Ⅱ.The survival rate at 7 days after H/I was recorded.The animals were sacrificed at 7 days after H/I.The brains were removed and the right and left cerebral hemispheres (CH) were weighed separately.The ratio between left/right CH was calculated.The density of normal neurons in ventral posterior inferior thalamic nucleus and posterior cingulate cortex in left and right CH were measured and the ratio of the density of normal neurons in the left to right CH was calculated.Results Compared with group Ⅰ,the weight of left cerebral hemisphere,ratio between left/right CH,and ratio of the density of normal neurons in the left to right CH were significantly decreased in other five groups (P ＜ 0.05).Compared with group Ⅱ,the weight of left cerebral hemisphere,ratio between left/right CH,and ratio of the density of normal neurons in the left to right CH were significantly increased in groups Ⅲ,Ⅳand Ⅴ (P ＜ 0.05).There were no significant differences in the indices nentioned above among groups Ⅲ,Ⅳand Ⅴ (P ＞ 0.05).There was no significant difference in the survival rate among groups Ⅱ-Ⅵ (P ＞ 0.05).Conclusion Inhalation of 1.5％ isoflurane for 30 min within 6 h after cerebral H/I can reduce the cerebral injury in neonatal rats.
