Objective To evaluate the effects of different doses of dexmedetomidine administered intranasally on the median effective target plasma concentration (EC50) of propofol inhibiting responses to laryngeal mask airway (LMA) insertion in the pediatric patients.Methods American Society of Anesthesiologists physical status Ⅰ or Ⅱ pediatric patients of both sexes,aged 1-3 yr,with body mass index of 20-26 kg/m2,scheduled for elective surgery under general anesthesia,were divided into 3 groups using a random number table:control group (group C),dexmedetomidine 1 μg/kg group (group D1) and dexmnedetomidine 2 μg/kg group (group D2).At 20 min before induction of anesthesia,dexmedetomidine 1 and 2 μg/kg (diluted to 1 ml in normal saline) were intranasally administered in D1 and D2 groups,respectively,and the equal volume of normal saline was intranasally administered in group C.Children were separated from their parents at 20 min after intranasal administration and admitted to the operating room.The target plasma concentration of propofol was determined by modified Dixon's up-and-down method.The initial target plasma concentration of propofol was set at 5.4 μg/ml.The target plasma concentration of propofol was increased/decreased by 10% in the next patient according to the response to LMA insertion,and the ratio between the two successive concentrations was 1.1.Patients' sedation status and LMA acceptance were evaluated when patients were separated from their parents.Patient's satisfaction with sedation and with LMA acceptance was recorded.Probit analysis was used to calculate the EC50 of propofol inhibiting responses to LMA insertion.Results Compared with group C,the satisfactory rates of sedation and LMA acceptance were significantly increased,and EC50 of propofol inhibiting responses to LMA insertion was decreased in D1 and D2 groups (P<0.05).Compared with group D1,the satisfactory rates of sedation and LMA acceptance were significantly increased,and the EC50 of propofol inhibiting responses to LMA insertion was decreased in group D2 (P<0.05).Conclusion Dexmedetomidine 1 and 2 μg/kg administered intranasally both can decrease the EC50 of propofol inhibiting responses to LMA insertion in the pediatric patients,and 2 μg/kg produces better efficacy.

The in-vitro fertilization and embryo transfer technique has been widely applied in human insemination. The rate of successful insemination is gradual y rising, and the in-vitro fertilization directly determine the insemination outcome.
OBJECTIVE:To evaluate the difference between the two common using insemination methods, microdrop and open, in in-vitro fertilization and embryo development.
METHODS:A randomized study was conducted to compare microdrop and open insemination methods among non-male factor patients undergoing in-vitro fertilization and embryo transfer. A total of 1 175 cases were enrol ed in the research. There were 573 cases in the microdrop group, and 602 cases in open insemination group. The fertilization rate and embryo development in the two groups were compared.
RESULTS AND CONCLUSION:The fertilization failure rate [total fertilization failure rate+low fertilization rate (<25%oocytes fertilized)] in the microdrop insemination group was higher than in the open insemination group (11.9%, 3.3%, P<0.001), while the good quality embryo rate and pregnancy rate did not differ significantly between the two groups (al P>0.05). The open insemination method is a simple insemination method with a lower fertilization failure rate. As the fertilization is a highly complicated process involving many extrinsic and intrinsic factors, further study is needed to confirm the effects of the two insemination methods on in-vitro fertilization outcome.

AIM: To examine the relation between serum concentrations of interleukin-18, interleukin-10, interleukin-6 and acute coronary syndrome (ACS). METHODS: Serum concentrations of IL-18, IL-10, IL-6 were measured in 17 patients with acute myocardial infarction (AMI), 30 patients with unstable angina pectoris (UAP), 15 patients with stable angina pectoris (SAP) and 20 controls by enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA).The relation between IL-18, IL-6 and IL-10 was compared. RESULTS: Serum concentrations of IL-18, IL-6 were significantly increased in the AMI and UAP groups in comparison with the SAP and control groups. Conversely, serum concentrations of IL-10 were significantly decreased in the AMI and UAP groups in comparison with the SAP and control groups. The correlation of concentrations of IL-18 and IL-6 had no significance; but the levels of IL-18 and IL-6 were negatively correlated with IL-10. CONCLUSION: Serum IL-18, IL-6 concentrations increase while serum IL-10 concentration decreases in patients with acute coronary syndromes. The inflammatory imbalance between IL-18, IL-6 and IL-10 may play an important role in the instability of atherosclerotic plaque.
