Objective To compare success rate of intubation and safety of two types of video laryngoscopes during anesthesia in uvulopalatopharyngoplasty surgery (UPPP) for obstructive sleep apnea syndrome (OSAS) patients. Methods UPPP surgery were operated to 60 patients between January and October of 2013 and those patients were randomly divided into McGrath MAC video laryngoscope group (M group), GlideScope video laryngoscope (G group), and SHUCMAN direct la-ryngoscopy (S group), with 20 patients per group. Mallampati classification scores, Cormack-Lehane grade, intubation suc-cess rate, pre-intubation vs post-intubation heart rate and blood pressure changes were recorded and compared. Results Mallampati classification scores were not significantly different between these three groups, and Cormack-Lehane grade be-tween M group and G group were also not statistically different. M and G group had distinct advantages in Cormack-Lehane grade, success rate in intubation, heart rate, blood pressure at completion of intubation (T3) and 1 minute after intubation (T4), and the differences are statistically significant (P < 0.05). Blood pressure changes were stabler in G group than M group. Conclusion The two video laryngoscopes used in anesthesia intubation during UPPP surgery can both effectively re-veal the structure of the throat, but also work with high success rate and safety. What’s more, in this study the McGrath MAC video laryngoscope was shown to be superior to GlideScope video laryngoscope.

Objective To study the biomarker panel of superficial bladder transitional cell carcinoma(SBTCC)and analyze the biological pathway in tumorigenesis by Shotgun proteomics strategy.Methods Normal urothelium cells and cancer cells were harvested by laser capture microdissection from clinical specimen and the proteomic expression profile was identified by two-dimensional liquid chromatography tandem mass spectrometry.The isoelectric point,molecular weight,grand average of hydropathicity,transmembrane helices were analyzed by using proteomics tools.Gene ontology was used to comment the identified proteins.The pathway analysis was performed by ArrayTrack software,and visualized by GenMAPP.Results There were 440 and 218 proteins expressed in cancer cells and normal cells respectively,among them 388 proteins were differerntially expressed.All the database about identified proteins was deposited in an accessible form to researchers at http://www.Proteome-SBTCC.org.cn and http://www.Proteome-NHTE.org.cn.There were 267(68.8%)differentially expressed proteins which had GO biological process comments.The biological pathwavs of these proteins included MAPK signaling pathway,focal adhesion,oxidative phosphorylation,ECMreceptor interaction,etc.Conclusion Shotgun strategy proteomies database of normal transitional epithelium and SBTCC is successfully constructed.And the basis for the understanding of cell biology and discovery of biomarker panel for SBTCC iS provided.

Immobilization conditions of Candida tropicalis to be absorbed in polyurethane foam carrier materials were studied on the xylitol production from corn hemicellulosic hydrolysate. Optimum batch-fermentation conditions were as follows: inoculum amount, 7% (volume ratio); polyurethane foam quantity, 1.0 g/100 mL; 30?C; initial pH, 6.0. Shaking speed was divided into two-phase to accommodate the dissolved oxygen, with 200 r/min at 0~24 h and 150 r/min at 24 h~46 h. The immobilized cells on polyurethane foam carrier have high density and good resistance to inhibitors in the hydrolysates. Average xylitol yield and volumetric productivity of polyurethane foam immobilized fermentation were much higher than the fermentation without immobilization. Corn cob hydrolysates can be directly biotransformed to xylitol without decoloration or ion-exchange treatment. This process can effectively reduce production costs, and it shows broad prospects of applications. Average xylitol yield was 67.6% and xylitol volumetric productivity was 1.92 g/(L?h).

Objective To evaluate the reasons for intrathecal administration of vincristine,the characteristics of patients with nerve damage,and the effective rescue measures and outcome prognosis.Methods Electronic literature databases,English and Chinese Paper Documents databases,and Network Engine were searched for Case Reports of inadvertent intrathecal injection of vincristine.SPSS 15.0 was used for statistical analysis.Results Analysis of 32 cases report showed that the intrathecal injection of vincristine in patients had adverse outcome.Of these cases 25 led to death,and survival of cases was associated with lower limb paralysis or quadriplegia.Fatalities appeared due to a progressively ascending myeloencephalopathy.Early recognition and immediate treatment with CSF drainage appeared to be the only intervention that had improved patients' survival.The survival curves of different surgical treatments,whether or not to use folic acid treatment,whether or not to use glutamate treatment,whether or not to use pyridoxinetreatment,was a significant difference.Conclusions Timely ventriculo-lumbar washout,using folic acid treatment and glutamate treatment appear critical.It is difficult to obtain satisfactory clinical outcome,so the key lies in the implementation of effective preventive measures.
