Glioma is the most common form of brain cancer. Despite recent advances in the treatment of solid tumors, there are few effective treatments for malignant gliomas due to its infiltrative nature. It has important significance to improve the treatment of glioma through in-depth understanding the intracerebral metabolic characteristics and pharmacokinetics of chemotherapeutics. Brain microdialysis (B-MD), an effective method to monitor central nervous system anticancer drug disposition, conditions of drugs through the blood-brain barrier, basic pathophysiologic metabolism, bioactive compounds and the changes of neurotransmitter in brain, provides the unique opportunity to allow the simultaneous determination of unbound concentrations of drugs in several tissues, and directly measure gliomas biochemistry continuously. B-MD has been able to monitor the change of brain drugs, metabolites and neurotransmitters, dynamic analysis of the drug concentration and pharmacological effect after administration, pharmacodynamic interaction between drugs, receptor mechanism of drug transport, as well as feedback information of internal environment. B-MD is expected to provide reference for clinical individual chemotherapy of glioma, but also provide powerful tools for the evaluation of new anticancer drugs in vivo. In this review, a comprehensive overview of B-MD for studies on glioma is elucidated with special emphasis on its application to neurochemistry and pharmacokinetic studies.

BACKGROUND:Adipose-derived stem cels are a kind of mesenchyam stem cels with multipotent differentiation capacity, which have more advantages than bone marrow mesenchymal stem cels in tissue engineering research. OBJECTIVE: To establish a method to isolate and purify adipose-derived stem cels from human subcutaneous adipose tissues folowed byin vitro amplification and osteoblastic/adipogenic differentiation.
METHODS: Adipose-derived stem cels were isolated from human subcutaneous adipose tissue and cultured by density gradient centrifugation and adherent culture. Cel morphology and growth features were observed under inverted microscope. Adipose-derived stem cels at passages 2 and 5 were selected for viability measurement using cel counting kit-8 method, and then cel growth curves were drawn. The immunophenotype identification was analyzed by flow cytometry. Passage 5 cels underwent osteoblastic/adipogenic induction to confirm the multi-differentiation potential.
RESULTS AND CONCLUSION: (1) Using density gradient centrifugation and adherent culture method, high-purity human adipose-derived stem cels can be successfuly isolated from human adipose tissues. (2) The growth process of human adipose-derived stem cels includes stagnant phase, logarithmic phase and plateau phase, which meets the growth rhythm of normal cels. Moreover, the population doubling time is shorter. (3). Human adipose-derived stem cels are positive for stem cel-related antigens, with low immunogenicity and the multi-differentiation potential. (4) Labeling human adipose-derived stem cels with DAPI is a simple efficient labeled method, and the labeling rate is high but the cytotoxicity is low

Cell viability of Pichia pastoris was detected by flow cytometry (FCM) with two reagents fluorescein diacetate (FDA) and propidium iodide (PI). Compared with FDA/PI double-stained dot plots and PI single-stained dot plots,the latter could divide dead and living cells into two separate zones,and get the correct proportion. Then PI single-stained method was used to detect the change of cell viability in Pichia patoris fermentation. At glycerol batch and fed-batch phase,little dead cells were detected. At methanol fed-batch phase,cell viability decreased when cell weight increased,and was only 73.8% at 88 h.

The intracellular hepatitis B surface antigen (HBsAg) content per cell was increased by 7.2-fold in the culture with 1.5% dimethyl sulfoxide (DMSO) compared with that in the control without DMSO, while the extracellular HBsAg production and specific productivity were only improved by 70% and 3.2-fold, respectively. Electron microscope has been employed to reveal large dilated structures within recombinant CHO cells in the presence DMSO. The dilated structures have a distribution within whole cytoplasm, and some dilated areas were engulfed in the nucleus. These large, dilated structures were not observed in the control. Immunogold labeling was used to discover the accumulated HBsAg was localized within these dilated areas, and some HBsAg-specific labels were detected in the nucleus membrane, owing to the encroachment of the dilated areas upon nucleus. The result could help to reveal the mechanism of intracellular HBsAg accumulation in the presence of DMSO.

Objective:To analyse the methord and effects of intermaxillary traction(IMT)screws used in the treatment of jaw frac-ture.Methods:In the treatment of 1 68 cases of jaw fracture IMT screws were used for the restoration of normal and stable occlusion. The screw number,position,traction effect and postoperative complications of the treatment were analysed.Results:705 screws were used in 168 patients,4 screws were used in each of 147 cased (88%),6 in 12(7%),5 in 9(5%).336(47.7%)screws were fixed between the roots of first and second premolar,292(41 .4%)between the roots of canine and first premolar,50 (7.1%)be-tween the roots of second premolar and first molar,27(3.8%)between the other tooth roots.Normal postoperative occlusion relation was achived by the use of screws in 92 cases without traction.Occlusion disharmony or deviation was found in 76 cases by the used of screws and was restored to normlal by 1 4-day traction in 71 cases.The total efficiency of the treatment was 97%.Pain of the mucosa surrounding the screws was observed in 23 cases (1 3.7%).Root damage,traction screw loosening and adjacent tooth dislocation were observed in 1 3(1 .8%),1 1 (1 .6%)and 2(0.3%)cases respectively.Conclusion:For the fixation of IMT screws,the posi-tions between tooth root from canine to first molar were most common and safe.The fixation point should be in 5 ~8mm below the gin-gival margin.Use of 4-6 screws can meet treatment need.
