Objective To determine the ED50 of remifentanil needed for tracheal intubation without neuromuscular relaxant in children when combined with sevoflurane inhalation.Methods Twenty-five ASA Ⅰ or Ⅱ children of both sexes,aged 4-9 yr,scheduled for elective surgery under general anesthesia were enrolled in this study.Anesthesia was induced with inhalation of 5% sevoflurane in 100% oxygen and PETCOM2was maintained at 30-35 mm Hg.Remifentanil was injected intravenously over 30 s after 3 min inhalation of sevoflurane.Tracheal intubation was performed 90 s after the completion of remifentanil injection.The experiment was performed using the modified Dixon's up-and-down method.The initial dose of remifentanil was set at 1.2 μg/kg and the ratio between two successive doses was 1.2.Intubation conditions were assessed by a blinded observer using Viby-Mogensen scale.If the conditions were not good,roenronium 0.3 mg/kg was then injected intravenously to facilitate intubation.The ED50 of remifentanil and 95% confidence interval (95% CI) were calculated.Results The ED50 of remifentanil combined with inhalation of scvoflurane required for successful intubation was 0.68 μg/kg in the absence of neuromuscular relaxant,and 95% CI was 0.65-0.71 μg/kg.Conclusion The ED50 of remifentanil required for tracheal intubatiun without neuromuscular relaxant drug is 0.68 μg/kg (95% CI 0.65-0.71 μg/kg) when combined with 5% sevoflurane inhalation in children.

"Vessels Collateral Theory", as the inherit and development of "blood vessels" in Huangdi Neijing, is a systematic system by integrating severe vascular diseases. In this article, by taking cardiovascular diseases (CVD) as a cut-in point, roles of "minute collateral-microvascular" lesions in the occurrence and development of CVD were further explored. The interventional effect of collateral-unblocking medicines under the guidance of Vessels Collateral Theory was also in-depth explored, hoping to leading Chinese medical prevention and treatment of CVD.

The volatile components of roots and stems of Zanthoxylum nitidum were investigated by supercritical fluid carbon dioxide extraction (SFE-CO2) and gas chromatography-mass spectrometry(GC-MS). Thirty-one and fifty-one compounds were identified in the supercritical extracts from roots and stems of Z. nitidum, respectively, and total twenty-seven compounds were the common constituents. Among them, the major constituents in root and stem supercritical extracts were spathulenol (18.49 and 26.18%), n-hexadecanoic acid (14.24% and 12.79%), ar-tumerone (6.95% and 8.88%), oleic acid (8.39% and 5.71%) and hexanoic acid (4.39% and 7.78%). The in-vitro MTT assay showed that the volatile components of roots and stems of Z. nitidum did not exhibited any cytotoxic activity against human cancer Huh-7 and normal IEC-6 cells. These results indicated the same nature of the volatile constituents in the root and stem of Z. nitidum. This investigation may provide further evidence for expansion of medicinal parts of Z. nitidum.

Objective To evaluate the reliability of Amsterdam Preoperative Anxiety and Information Scale (APAIS) score in evaluating the preoperative anxiety of Chinese people.Methods One hundred sixty Chinese patients of both sexes, aged 18-60 yr, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, scheduled for elective surgery, were enrolled.Preoperative anxiety of the patients was assessed with APAIS score and Spielberger's State-Anxiety Inventory (S-AI) questionnaire during the preoperative interview.Cronbach's alpha of total anxiety and need for information scores was calculated.Four thresholds of total anxiety score in identifying preoperative severe anxiety was set as 10, 11, 12 and 13.S-AI questionnaire was considered as the standard, and the correlation between total anxiety score and S-AI questionaire was tested.Results The Cronbach's alpha of total anxiety and need for information scores was 0.84 and 0.71, respectively.When the threshold of total anxiety score in identifying preoperative severe anxiety was 12, the total anxiety score was highly correlated with S-AI questionnaire, the Kappa value was 0.62, 95％ confidence interval was 0.46-0.78, the sensitivity was 0.71, the specificity was 0.90, and the positive predictive value was 0.78.Conclusion APAIS score can be used to assess the preoperative anxiety of Chinese people.

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.

METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.

RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.

CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.

Objective Application of the second metatarpophalangeal joint by traction prolong trans- plant repair the defects in the metacarpophalangeal joint,reconstruct the function of it.Methods By means of the apparatus to prolong finger in advance,then transplant the second metatarpophalangeal joint to recon- struct metacarpophalangeal joint for seven cases of obsolete defects in the metacarpophalangeal joint.Results The average of finger prolong was 2.6 cm,consultation from 1 to 4 years.average 2.5 years,thai the trans- plant joints have all survived and osteal concrescence.Through the criterion Chinese Medical Association,good rate was 85.7%. Conclusion It' s a good method to repair obsolete defects in the metacarpophalangeal joint by transplant traction prolong of the second metatarpophalangeal joint.

Objective To investigate the relationship between expression of active form of caspase-3 and cell cycle in Fas-mediated apoptosis of B lymphocytoma cell line MML-1. Methods MML-1 cells were incubated with agonistic anti-Fas antibody for different time,and cell apoptosis was induced.Cell apoptotic rates were analysed by flow cytometry,and sensitivity of MML-1 cells to apoptosis was determined.The expression of active form of caspase-3 was analysed by double staining with PI-Triton X and FITC-active caspase-3.Cyclin A,B_1 and E were selected as cell cycle markers for S,G_2/M and G_1 phase of MML-1 cells,and the expression of active form of caspase-3 was detected by flow cytometry. Results The cell apoptotic rate reached 56% after induction by Fas for 6 h.After induction by Fas for 4 h,the active form of caspase-3 was mainly expressed in cells of G_1 phase,while rarely in cells of S and G_2/M phase.Cells with negative cyclin A and B_1 and positive cyclin E expressed active form of caspase-3. Conclusion The expression of active form of caspase-3 in MML-1 cells mediated by Fas might be cell cycle dependent.Cells entering into late G_1 and early S phase first express active form of caspase-3,and their sensitivity to Fas-mediated apoptosis is the highest.

Objective We examined the Grp78, ERK1/2 and phospho-ERK1/2 expressions in hepatocellular carcinoma(HCC) tissue samples in vitro, we interfered the expression of Grp78 in SMMC-7721 cells to explore whether Grp78 is involved in ERK1/2 signal pathway. Methods The Grp78, ERK1/2 and phospho-ERK1/2 expressions were detected by immunohistochemistry and confirmed by Western blotting in 47 HCC tissue samples. The Grp78 expression in SMMC-7721 cells was interfered by plasmid transfection and siRNA, ERK1/2 phosphorylation and expression were determined by Western blotting. Results The Grp78 expression was significantly correlated with ERK1/2 and phospho-ERK1/2 in HCC tissue samples. Overexpression of Grp78 promoted ERK1/2 phosphorylation in SMMC-7721 cells and the increased ERK1/2 phosphorylation was inhibited by Grp78 knockdown. Conclusion Grp78 is involved in the regulation of ERK1/2 signal pathway and might be a potential target for the comprehensive therapy of HCC.
