AIM: To determine the interactions with response-surface modeling methodologies when sevoflurane (Sevo) and remifentanil (Remi) were administered simultaneously. METHODS: (1) Patients, Study design and drug delivery: Based on parallel slices design, sixty-five patients were randomly assigned to inhale a specific end-tidal concentration of sevoflurane (0.3% to 3.4%), with different level of remifentanil (0-10 ng/mL). The responses to laryngoscopy were observed for each given concentration pair. (2) Pharmacokinetic/pharmacodynamic analysis with response surface mode: The probability of no response (P) was assessed in the modeling process as below. P=(Us+Ur)r/[U50/I(Q)]r+(Us+Ur)r RESULTS AND DISCUSSION: NONMEM estimated average values (RSE%) of the model parameters for laryngoscopy of C50,Sevo, C50,remi, U50, r, Imax and Qmax are 1.71% (12.9), 12.4 ng/mL (19.0), 6.62 (10.6), 1.53 (8.76), 2.31 (8.23), 0.706 (2.46), respectively. The inter-individual variability (CV%) in parameter Imax and inter-occasion variability (S.D.) in this model are 12.7 and 0.0316, respectively. It is concluded that the response-surface modeling approach provided a novel method to study drug-drug interactions.

Objective To evaluate the performance of the remifentanil target-controlled infusion(TCI) system(Minto model) during laparoscopic surgery under inhalation and intravenous anesthesia.Methods A total of 15 patients scheduled for laparoscopic surgery received remifenanil by TCI,and the anesthesia was maintained with inhalation of isoflurane and intermittent intravenous vecuronium.The target remifentanil plasma concentration(Cp) was increased step by step,with the concentration changed at intervals of 30 minutes.The beginning Cp was 3 ng/ml,then increased to 6 ng/ml,9 ng/ml.Blood samples were taken from radial arterial before anesthesia induction and 30 minutes after adjustment of Cp to determine the concentration of remifentanil using high performance liquid chromatography-tandem mass spectrometry(HPLC/MS/MS).The performance of the TCI system was evaluated by median performance error(MDPE),median absolute performance error(MDAPE) and wobble.Results The MDPE,MDAPE and wobble of the remifentanil TCI system were 8.78%,16.11% and 14.55%,respectively.The measured concentrations of remifentanil were positively correlated with Cp(r=0.891,P=0.000).The linear equation was Y∧ =1.1046X+0.1837.Conclusions The remifentanil TCI system with Minto pharmacokinetic model can meet the requirements of clinical anestehesia for Chinese patients within clinical treating concentration.

RESULTS: The content of pachymic acid in Fushen is the highest in different parts and the content of pachymic acid in Guangxi province is the highest in five localities. CONCLUSION: The content of pachymic acid was obviously variable in different parts and this result made the basis of the application of with the different parts of Poria. The content of pachymic acid wasn't obviously variable in different localities.

BACKGROUND: Prevention of implant from inflammation was an effective method to reduce expulsion rate of stainless steel micro-screw implant, and develop new type of antibiotic material.OBJECTIVE: To evaluate the cytotoxicity of a new type of antibiotic stainless steels.METHODS: Metal test samples (antibiotic stainless steel, medical stainless steel, and medial pure titanium) were made into rectangular solids with length of 15 mm × 10 mm × 3 mm. Samples were cleaned with high temperature and high pressure. Alloy leaching liquor was prepared with DMEM culture media according to the ratio betwean surface area and volume of culture solution (3 cm~2/mL). The leaching liquor was maintained in incubator at 37 ℃ for 96 hours, and then degerming was performed using microporous membrane. 6.4% phenol was added, which was considered as the positive control group, and DMEM culture media was considered as the blank control group. Growth of MG63 cells was observed under inverted phase contrast microscope;absorbanca of cells cultured for 24, 48, 72, 96, and 120 hours was detected using MTT test; cytotoxicity of antibiotic stainless steels was evaluated.RESULTS AND CONCLUSION: ① At 24 hours after culture, calls in the positive control group was abnormal; while, cells in other groups were well adherent-grew. ② After 48 hours of culture, with the culture time increased,cytotoxicity was detected out in the positive control group; cells in other groups and blank control groups were normal and grew well. Afew of cells in stainless steels group showed karyopyknosis. ③ The absorbance was the highest of medical pure titanium, and then of antibiotic stainless steel and of medical stainless steel, while there was no significant difference between the three materials. ④ The level of cytotoxicity was grade 0. The results suggested that the antibiotic stainless steel which had the same cytotoxicity grade as medical stainless steel and pure titanium was in line with the requirement of its clinical application.

Objective To assess the effects on volume of uterine and the dominant fibroid by a re-new radiofrequency ablation ( RFA ) on uterine myomas and disemboweling them from uterine after RFA . Methods Three hundred and eight -three patients were treated by RFA and followed up at 1, 3, 6 and 12 months,165 of them by usual RFA , 163 by improved RFA.To them which myomas diameters were >5cm, 55 cases were added by disemboweling the myomas out of the body after one month of improved RFA .But 66 were not disemboweled.The pre-and postoperative uterine and myoma volumes were measured by 3D ul-trasonography .Results The volume of uterine and the dominant fibroid were reduced in usual and im-proved RFA groups , especially in improved group ,but the difference was no significantly ( P >0.05 ) .In the groups of which myomas diameters were >5cm , the median reduction rates of uterine and myoma vol-ume was more significantly in disemboweling group than un -disemboweling one after 3 and 6 months ( P <0.05 , P <0.01 ) .The overall effective rates were 90.90%,93.25%,100%and92.42%respectively in u-sual and improved RFA groups( P >0.05),and in disemboweling and un -disemboweling groups ( P >0.05).But the obvious effective rates have significant difference in disemboweling (81.82%)and un-dis-embowelin(41.94%)group ( P <0.01).Conclusion Disemboweling myomas from uterine after RFA can increase the clinical effects significantly .

Objective To investigate the value of serum soluble leukocyte differentiation antigen 14 subtype (sCD14-ST,presepsin) combined with national early warning score (NEWS) for predicting the prognosis of emergency patients with sepsis.Methods To select 119 patients who came to the emergency department of Beijing Hospital with sepsis from September 2009 to July 2015 as the objects of the study.The serum samples were collected immediately as they came,the presepsin was measured,and the NEWS scorescalculated.Patients were divided into survival group (81 cases) and death group (38 cases) according to the 30-day prognosis,and the value of the presepsin,NEWS score and presepsin + NEWS score in the assessment of prognosis were compared.Results Presepsin and NEWS scores both were higher in the death group than the survival group.Presepsin and NEWS were the independent risk factors of the 30-day mortality of patients with sepsis.Under the ROC curve area (AUC) of presepsin and NEWS were 0.842 and 0.823;the combination of Presepsin and NEWS was 0.906.When presepsin > 927.5 pg / mL and NEWS > 6.5 points,it can significantly improve the efficacy of predicting prognosis.Conclusions Serum presepsin is a good indicator to judge the prognosis of patients with sepsis,and the combination with NEWS can improve the ability to predict the risk of septic death.
