Objective To explore the clinical meanings of serum CA19-9 levd in hepatocirrhosis patients. Methods 61 hepatitis B and hepatocirrhosis patients were as treatment group, and 35 normal were as control group. The content of serum CA19-9 was measured by dectrochemistry lighting and the liver function was determined too. According to Child-Pugh liver function integral method,the treatment group was divided into 27 cases of A grade,20 cases of B grade and 14 cases of C grade. Results The serum CA19-9 level in hepatocirrhosis patients was higher than that of normal group significantly(P< 0. 005 ). The serum CA19-9 level decreaed obviously through the treat- ment,thereinto A and B grade fell evidendy in the Child-Pugh liver function integral method( P < 0. 005). C grade was not significantly different(P<0.05 ). The serum CA19-9 levd was positivdy associated with TBiL, ALT and AST of liver function integral method. Conclusion The serum CA19-9 levd of hepatocirrhosis patients is improved in different degrees. And it can be a prognostic target and used to estimate the degree of damage of liver function of hepatocirrhosis patients.

Objective To compare the effect of different stylet angulation and endotracheal tube camber on time to intubation with Tosight?? video laryngoscope.Methods One hundred and twenty patients of 18 to 55 years old,ASA Ⅰ or Ⅱ,with no difficult airway signs and history,were random-ized into three groups with different endotracheal tube bending angle:group A(angle 40°),group B (angle 60°)and group C(angle 80°).For patients in all three groups,after rapid sequence induction, the Tosight?? oral intubation were applied.The Cormack-Lehane grading,glottic exposure time, times of tracheal intubation,hemodynamic response and complications were recorded.Results Tra-cheal intubation with the Tosight were successfully completed for all three groups.The success rate of first time intubation in groups A,B and C were 37 (92.5%),39 (97.5%)and 40(100.0%),respec-tively.3 patients in group A and 1 patient in group B finished the intubation with the second try after the stylet angle was changed.The mean time to glottic exposure had no significant difference in groups A,B and C.The time to complete tracheal intubation in group C was significantly shorter than that in groups A and B (P < 0.05 ).There was no significant hemodynamic changes for all three groups,and no serious complications were detected.Conclusion When the Tosight?? is used for adult endotracheal intubation 40°,60°,80°angled stylets can all well assist endotracheal intubation.Among which 80°angled slylet has obvious advantages in intubation success rate and shortest intubation time.

Objective To compare the intubating conditions between dexmedetomidine and remifentanil when combined with sevoflurane-nitrous oxide (N2O) for anesthesia induction in the pediatric patients.Methods A total of 122 pediatric patients,aged 4-10 yr,of American Society of Anesthesiologists physical status Ⅰ,undergoing elective plastic surgery,were randomly divided into dexmedetomidine group (group D,n =61) and remifentanil group (group R,n=61).Eight percent sevoflurane and 60％ N2O were inhaled for induction of anesthesia,and the fresh gas flow was set at 6 L/min.After disappearance of eyelash reflex,dexmedetomidine 1 μg/kg and remifentanil 1 μg/kg were intravenously injected over 50-60 s in D and R groups,respectively,and 1 min later tracheal intubation was performed.The intubating conditions were graded,and the satisfactory intubating conditions and successful intubation were recorded.The development of adverse cardiovascular reactions and complications such as hyoxemia and laryngospasm before and after intubation and postoperative pharyngodynia was recorded.Results Compared with group D,no significant change was found in the success rate of intubation,rate of satisfactory intubation,intubating condition grade or incidence of postoperative pharyngodynia (P＞ 0.05),and the incidence of hypertension and sinus tachycardia after intubation was significantly increased in group R (P＜0.05).No pediatric patients developed hyoxemia,laryngospasn or sinus tachycardia in two groups.Conclusion When 8％ sevoflurane and 60％ N2O are inhaled for anesthesia induction,combing with dexmedetomidine 1 μg/kg produces better clinical efficacy than combing with remifentanil 1 μg/kg in improving the intubating conditions for pediatric patients.
