BACKGROUND: The application of deacetylated chitin (chitosan, DC) prepared by traditional technique was limited because of its lower degree of deacetylation, impurity and relative lower molecular mass.OBJECTIVE: To improve the traditional technique for extraction and preparation of DC from the rustae f oratosquila oratoria.DESIGN: Contrasting observation.SETTING: Shandong Institute of Biopharmaceutics.MATERIALS: The experiment was carried out in the Shandong Key Laboratory for iopharmaceutics, Shandong Institute of Biopharmaceutics from February 2003 to January 2004. Experimental nstrument: Mettler AE240 electronic analytical balance and ZK-40AB electrothermal vacuum drying oven were rovided by Mettler-Toledo Instruments Co., Ltd. And ShangHai Shuli Instruments Co.,Ltd., respectively. Xperimental materials: oratosquila oratoria was purchased from Jinan aquatic products market.METHODS: ①C as traditionally prepared from chitin by decoloring with strong oxidant and deacetylating with concentrated alkaline liquor under high temperature. Chitin was extracted from crustae of shrimp and crab fter decalcification with diluted acid and deproteinization with diluted base. ②The improved preparation echnique: The crustae of oratosquila oratoria was decalcificated and decolorized with diluted acid, and as deproteinized and decolorized with diluted base at room temperature, and then the chitin was obtained fter the second decalcification and decolorization with diluted acid. The crude DC was obtained from hitin after deacetylation and decolorization with concentrated ase at 55-65 ℃. The crude DC was issolved n diluted acid and filtered. The filtrate was collected, precipitated with dilute base. After filtering, he sediments were retained, washed with water and dried. Then pure DC was obtained.MAIN OUTCOME MEASURES: he comparison between improved technique and traditional technique; Color, dissolvability in diluted cid, ield, degree of deacetylation and dynamic viscosity of DC prepared by different techniques.RESULTS: ①echnique comparison: Compared with traditional technique, the reaction of improved preparation technique as milder, and the deproteinization was at room temperature; it did not need an isolated decolorization;deacetylation was at low temperature, and had a refine process. ②Detection indexes of DC: he yield of DC prepared by improved technique was little lower than that by traditional technique (15%, 7% respectively). The degree of deacetylation and dynamic viscosity were both higher than those by raditional technique (＞ 95%,＜ 70%; ＞ 120mPa·s,＜ 80 mPa·s , respectively). The color was white or lmost white, which was better than that by traditional technique (yellow or gray). The DC could ompletely issolve in dilute acid, and the dissolvability was better than that by traditional technique (dissolved artly in dilute acid).CONCLUSION: Compared with the traditional technique, the improved technique was mpler and the reaction conditions were milder. And also the quality of obtained DC was obviously improved.

Objective To investigate the relation between the expression of toll receptor-4 (TLR-4) and the increase of blood brain barrier (BBB) permeability in the rats with acute pancreatitis.Methods Male Sprague-Dawley rats were randomly divided into 8 groups:control group;acute edematous pancreatitis (AEP) 2 h,6 h groups;acute necrotizing pancreatitis (ANP) 2 h,6 h,12 h,24 h,48 h groups with 8 rats in each group.The BBB permeability,pathological score of pancreas,TLR-4 expression were determined and the relationships between them were analyzed.Results The BBB permeability in control group;acute edematous pancreatitis (AEP) 2 h,6 h groups;ANP 2 h,6 h,12 h,24 h,48 h groups were 1.55±0.29,1.64±0.17,1.69±0.24,1.89±0.12,2.66±0.32,2.91±0.29,2.89±0.69 and 1.84±0.07,respectively;the pathological scores of pancreas were 0,2.38±0.92,3.13±0.64,8.50±1.07,9.75±0.71,10.25±1.28,11.13±1.25 and 10.13±1.13,respectively;there was no significant difference between AEP groups and control group,while there was significant difference between AEP groups and ANP groups (P＜0.05 orP ＜0.01).BBB permeability was correlated with pancreatic injury ( r = 0.626,P ＜0.01).There was no TLR-4 mRNA and protein expression in the control and AEP group,while they were significantly expressed in ANP groups,and the expression were positively related with BBB permeability ( r =0.208,P = 0.027 ).Conclusions BBB permeability was present in the course of ANP.Activation of TLR-4 signal pathway may be involved in the BBB permeability increase caused by ANP.

Objective To observe the sensitivity ofastrocytoma to chemotherapeutic drugs, in order to explore the drug selection using chemosensitivity testing in vitro on astrocytoma. Comparing different WHO grade astrocytoma to chemotherapeutic drugs sensitivity differences,providing the basis data for clinical treatment. Methods The astrocytoma cells were seperated and cultured in vitro from 142 tumor tissues by glioma resection, including 55 cases of low-grade astrocytoma (WHO grade Ⅰ , Ⅱ) and 87 cases of high-grade astrocytoma (WHO grade Ⅲ, Ⅳ). The proliferation inhibition and chemosensitivity of tumor cells to 11 drugs were investigated by using MTT method. Results There were 54.93% (78/142) patients recommended chemotherapeutic drug in 142 cases. The percentage was 41.82%(23/55) in the low-grade astrocytoma, and 63.22% (55/87) in the high-grade astrocytoma respectively. Teniposide,carboplatin,vincristine as the sensitive drugs were similar in different WHO grade astrocytoma. Conclusions The chemosensitivity testing could be used to filtrate sensitive drugs to clinical chemotherapy. The action is more prominent in high-grade astrocytoma than in low-grade astrocytoma. There is no difference in the choice of sensible drugs among different WHO grade astrocytoma.

Systemic lupus erythematosus (SLE) is a multiple organ autoimmune disorder, including the liver, but the possible reason in impairment in the liver is still unclear. Our present study assessed alterations of transcription factor Foxp3(+) regulatory T cells (Tregs) and several other immune molecules [programmed cell death 1 and its ligand (PD1 and PD-L1), and interleukin 10 (IL-10) and transform growth factor β (TGF-β)] in the liver and other major organs of lupus-prone BXSB mice by flow cytometry, real-time quantitative reverse transcription PCR, and enzyme-linked immunosorbent assay. Results showed that both frequency and number of Foxp3(+) Tregs were dramatically reduced in the thymus, spleen and kidney of the BXSB mice (P<0.05), but those in the liver were kept in nearly normal range, when compared to negative control C57BL/6 mice. In comparison to control mice, the mRNA levels of Foxp3, PD1 and PD-L1 were significantly decreased in the kidneys of BXSB mice (P<0.05), but there was no significant difference in the livers of the BXSB mice (P>0.05). Protein levels of IL-10 and TGF-β in serum showed no significant difference between BXSB and C57BL/6 mice, but were significantly increased in the kidneys and livers of BXSB mice as compared with those in C57BL/6 mice (P<0.05). These results suggest that reduced Foxp3(+) Tregs are involved in the pathogenesis of SLE in BXSB mice, and relatively higher number of these cells in the livers than in the other target organs could constitute a protective mechanism against hepatic lesions in lupus-prone mice, which may provide insights into development of new therapeutic approaches in SLE patients.
