With building up a clinical modification system model by upgrading the standard disease classification system architecture,to collect those huge amount of diagnosis names and codes in use,based on the model to screen and coordinate the relation of them,the tenth revision of the International Classification of Disease Clinical Modification of Beijing is implemented.This standard has been successfully applied for two years in all those secondary and above level hospitals in Beijing.It could well support the work of deploying Diagnosis Related Groups in Beijing and support not only those traditional applications of disease classification but also those new and advance requirements of information processing.

Objective To evaluate the accuracy of remifentanil target-controlled infusion (TCI) system in children.Methods Thirty ASA Ⅰ patients, aged 3-12 yr, weighing 10-40 kg, scheduled for elective ear-nosethroat or urological surgery, were randomly divided into 2 groups with 15 patients in each group:2 ng/ml remifentanil group (group Ⅰ) and 4 ng/ml remifentanil group (group Ⅱ). Anesthesia was induced with iv injection of propofol 2 mg/kg and TCI of remifentanil. Remifentanil was administered with a specific TCI system incorporating the pharmacokinetic parameters of Minto.The target plasma concentrations of remifentanil were set at 2 or 4 ng/ml. Tracheal intubation was facilitated with vecuronium 0.1 mg/kg after the children lost consciousness. The children were mechanically ventilated.Anesthesia was maintained with TCI of remifentanil, iv infusion of propofol and intermittent iv boluses of vecuronium. The target plasma concentration of remifentanil remained unchanged and bispectral index value was maintained at 45-65 or auditory evoked potentials index value ＜ 30 by adusting the infusion rate of propofol.Arterial blood samples were taken at 5, 10, 20, 30, 40, 50 and 60 min after TCI remifentanil was stared for determination of blood remifentanil concentrations by high performance liquid chromatography. Median prediction performance error (MDPE),median absolute performance error (MDAPE) and wobble of remifentanil TCI system were calculated. Results The measured concentrations of remifentanil were significantly higher than the target plasma concentrations in both groups (P＜0.05). The MDPE, MDAPE and wobble were 20.0% , 30.0% and 25.0% respectively in group Ⅰ , and 17.5%, 17.5% and 12.5% respectively in group Ⅱ . TheMDAPE and wobble were significantly decreased in group Ⅱ compared with group Ⅰ(P＜0.05).Conclusion When remifentanil is administered using a specific TCI system incorporating the pharmacokinetic parameters of Minto in children of 3-12 years old, the accuracy is not high.

Objective To evaluate the accuracy of remifentanil target-controlled infusion (TCI) system in children.Methods Thirty ASA Ⅰ patients (aged 3-12 years and weighing 10-40 kg) scheduled for elective ear-nose-throat or urological surgery were randomly divided into two groups (n =15 each):2 ng/ml remifentanil group (group Ⅰ) and 4 ng/ml remifentanil group (group Ⅱ).Anesthesia was induced with intravenous injection of propofol 2 mg/kg and TCI of remifentanil.Remifentanil was administered with a specific TCI system incorporating the pharmacokinetic parameters of Minto.The target plasma concentration of remifentanil was set at 2 or 4 ng/ml.Tracheal intubation was facilitated with vecuronium 0.1 mg/kg after the children lost consciousness.The children were mechanically ventilated.Anesthesia was maintained with TCI of remifentanil,intravenous infusion of propofol and intermittent intravenous injection of boluses of vecuronium.The target plasma concentration of remifentanil remained unchanged and bispectraI index value was maintained at 45-65 or auditory evoked potentials index value ＜ 30 through adjusting the infusion rate of propofol.Arterial blood samples were taken at 5,10,20,30,40,50 and 60 minutes after TCI of remifentanil was started for determination of blood remifentanil concentrations by high performance liquid chromatography.Median prediction performance error (MDPE),median absolute performance error (MDAPE) and wobble of remifentanil TCI system were calculated.Results The measured concentrations of remifentanil were significantly higher than the target plasma concentrations jn both groups (P ＜ 0.05).The MDPE,MDAPE and wobble were 20.0％,30.0％ and 25.0％ respectively in group Ⅰ,and 17.5％,17.5％ and 12.5％ respectively in group Ⅱ.The MDAPE and wobble were significantly decreased in group Ⅱ compared with group Ⅰ (P ＜ 0.05).Conclusion When remifentanil is administered using a specific TCI system incorporating the pharmacokinetic parameters of Minto in children of 3-12 years old,the accuracy is not high.

Objective To compare the analgesia effects of Oxycodone hydrochloride with Sufentanil in laparoscopic cholecystectomy (LC) anesthesia induction. Method Sixty patients scheduled for elective LC, ASAⅠ or Ⅱ , were randomly divided into two groups (30 in each): Oxycodone group (group O) and Sufentanil group (Group S). Induction of anesthesia: group O: Propofol 1.0 ~ 2.0 mg/kg, Oxycodone 0.3 mg/kg, Vecuronium 0.1 mg/kg. Group S: Propofol 1.0 ~ 2.0 mg/kg, Sufentanil 0.3 μg/kg and Vecuronium 0.1 mg/kg. The value of HR, SBP, DBP of the two groups were recorded in the operation room (T0), after anesthesia induction (T1), 1 min after insertion laryngeal mask (T2), the instant of pneumoperitoneum establishment (T3), separation of the gallbladder (T4), the time of wake up (T5), leave the recovery room (T6). The numeric pain rating scale (NRS) were recorded at T4, T5, 4 hours later (T7), 8 hours later (T8), one day later (T9). Then recorded the wake time and additional analgetic cases. Recorded the adverse reactions. Results The average HR, SBP and DBP fluctuations in the two groups were not more than 20.0 % of the basal values. There was no significant difference in wake time between the two groups. There were 11 cases of patients, the NRS>4, in Sufentanil group requires additional analgesics after they wake up, more than Oxycodone group (P = 0.040). The NRS score was lower in Oxycodone group than group S in T5, T7, T8, T9, but they had no statistically significant difference. There was no significant difference in adverse reactions between the two groups. Conclusion 0.3 mg/kg Oxycodone and 0.3 μg/kg Sufentanil for anesthesia induction of LC, the anesthesia and analgesia effect is good, can satisfy the clinical anesthesia and postoperative analgesic requirements. The analgesic effect of 0.3 mg/kg Oxycodone may be comparable or better than 0.3 μg/kg Sufentanil.

Objective To study whether the organs besides digestive system of musca domestica Ⅲ instar larvae have the capability of produceing musca β-glucosidase.Methods Tissues of malpighian tubules,trachea,epiploon and body wall of musca domestica Ⅲ instar lar-vae were dissected under anatomic microscope,and the expression of β-glucosidase gene in these dissected tissues were detected by reverse transcription PCR.And the tissue localization of β-glucosidase mRNA was further identified by in situ hybridization.Moreover,anti-cellulase was used to determinate the tissue distribution with immunohistochemical staining.The relative mRNA expression levels of musca domesticaβ-glucosidase gene in these organs were tested by real-time quantitative PCR.Results The reverse transcription PCR showed that the ampli-fication products of β-glucosidase gene were observed in tissues of malpighian tubules,trachea and body wall.β-glucosidase mRNA was shown in the epithelium cells of malpighian tubules,trachea and body wall by in situ hybridization,and it was almost the same in the results of im-munohistochemical staining.The real-time quantitative PCR showed that the relative expression quantity of β-glucosidase gene in malpighian tubules and body wall were higher than that in foregut,while it was lower in itrachea than that in foregut.And it was of statistical difference in gene expression level of β-glucosidase among these organs (P <0.05).Conclusion Malpighian tubules,trachea and body wall of musca domestica Ⅲ instar larvae have the function of secreting β-glucosidase.Combining with the characteristics of secreting β-glucosidase in most organs of digestive system,it may provide a new biological method for the prevention and treatment of human diseases transmitted by musca domestica with the use of taget gene β-glucosidase.

Objective To investigate the effects of laporoscopic resection applied to colorectal cancer patients on metabolism. Methods According to patients' choice of operation, either laparoscopic-assisted (n = 22, experimental group) or open(n = 27, control group) resection of colorectal cancer was performed. The levels of electrolyte were assayed preoperatively, postoperatively and on the time of 24 hours after opera-tion. Rseults There was no significant difference in the level of electrolyte before operation between the two groups (P > 0. 05). Compared with the preoperative period, the level of serum potassium in the both groups were significantly increased after operation(P < 0. 05), and 24 hours later, the levels of electrolyte was not significantly different in both the two groups (P > 0. 05). During the postoperative period, the level of serum potassium in the experimental group was lower than the control group(P <0. 05), while the level of HCO_3~- was higher than the control group(P <0. 05), and there were no significant differences in the level of serum sodium, chloride and calcium between the two groups(P > 0. 05). Conclusions Laparoscopic-assisted re-section of colorectal cancer gives lower levels of stress responses compared to open surgery. However, it shows higher effect on the level of HCO_3~- , and must be paid more attention during operative and postopera-tive period.

Objective To study emptying of gallbladder in children with functional dyspepsia(FD),and to investigate correlation of their helicobacter pylori(Hp) status and gallbladder emptying rate.Methods Sixty children with FD were studied,including 30 Hp-ne-(gative) and 30 Hp-positive children.Thirty Hp-positive children received triple eradication therapy 1 week.After 4 weeks,the Hp tests were taken again,27 children became Hp-negative,and the others were still positive eliminated from the study.The difference between the above groups in gallbladder volumes before breakfast and postprandial gallbladder emptying rate were compared.Results The gallbladder volumes before breakfast were bigger and the emptying rate of postprandial gallbladder of children with FD were lower than those of normal controls(P0.05).Conclusions Delayed emptying of gallbladder may cause FD in children.Hp infection isn′t associated with the gallbladder emptying rate.
