Objective:To investigate the expression of Toll-like receptors(TLRs)signaling pathway in chronic rhinosinusitis(CRS)with nasal polyps.Method:Gene microarray analysis was used to detect the expression of TLRs signaling pathway in CRS with nasal polyps.Result:Of 19 differentially expressed(two-fold changes),4genes were upregulated and 15 genes were downregulated.Conclusion:The differentially expressed genes in TLRs signaling pathway may exert its effect in the pathogenesis of CRS.In addition,the roles of TLR9 and its agonists need further study.

There are two populations of bacteria to affect the formation of urinary stones in humanity. The first one can promote the formation of urinary stone by increasing urinary pH, decreasing concentration of urinary inhibitors , and damaging the protective urothelial glycosaminoglycan layer. The second inhibit the formation of urinary stones. These bacteria ( mainly the intestinal oxalate degrading bacteria such as Oxalobacter formigenes, lactic acid bacteria, Enterococcus faecalis etc) can decrease urinary oxalate concentration by regulating exogenous oxalate. The problems faced and the developing direction were also indicated.

A? plays a crucial role in Alzheimer's Disease and the soluble A? oligomers have been recognized as the emerging neurotoxins,which ultimately cause memory impairment and neuronal loss through different mechanisms.The development of novel drugs targeting A? oligomers indicates new and promising therapy approaches for AD.The pathological roles as the proximal toxins in AD and the compounds,targeting soluble A? oligomers,which are currently in preclinical and early clinical development,are reviewed.

Objective To evaluate the feasibility of CT staging for esophageal cancer. Methods A retrospective analysis of 304 patients treated,from Jan. 1996 to Dec. 1998 chiefly with radiotherapy(126 conventional radiotherapy,55-65 Gy/27-35 fx/5.5-7.0 w;178 late-course accelerated hyperfractionated radiotherapy ,55-60 Gy/33-36 fx/ 4.5 -5.5 w)complete with CT data before treatment was done. The long survival was compared with pre-therapy CT findings and CT staging. ResultsThe survival rate of stage T1+T2 was very significantly different from those lesion with stage T3,T4(? 2=12.90,P0.05).The survival rates of patients positive for lymph nodes or distant metastasis were lower. Conclusion CT staging is quite optimal for non-operable esophageal cancer in clinical staging,as it is conducive to predict the prognosis.

AIM　The purpose is to construct D-hydantoinase genetic engineering strain for the purpose of the industrial production of D-p-hydroxyphenylglycine. METHODS　D-hydantoinase gene was created from Pseudomonas putida 9801 by PCR technique and inserted into pMD18-T vector. The recombinant plasmid was transformed into several Escherichia coli strains. The positive transformants with D-hydantoinase activity were obtained by the two step screening, digoxigenin DNA labeling in situ hybridization and D-hydantoinase activity assay. RESULTS　The D-hydantoinase activity of the genetic engineering strain E.coli BL21/pMD-dht was 1700 U*L-1 and increased as high as 8 times compared with those of wild-type strain Pseudomonas putida 9801. The subunit molecular weight of recombinant D-hydantoinase was about 53 kDa measured by SDS-PAGE. The amount of the recombinant D-hydantoinase was about 20 percent of total bacterial soluble proteins. CONCLUSION　The genetic engineering strain E.coli BL21/pMD-dht possesses the initial industrial production prospects.

Objective To study the implact of tacrolimus blood concentration (Tac) after renal transplantation on blood lipid and fasting glucose (FBG) in recipients.Method The recipients who regularly given Tac + mycophenolate mofetil + prednisone after renal transplantation were chosen and those had normal preoperative levels of blood lipid and fasting glucose as subjects.The recipients were classied into high concentration group,normal concentration group and low concentration group by comparing Tac blood concentration of different postoperative periods with corresponding normal concentration range.The changes of biochemical indexes such as steady Tac valley blood concentration,blood lipid and FBG were monitored,and the differences in blood lipid and FBG levels at different periods among three concentration groups were compared.Result TG level was significantly higher (P＜0.05),and HDL-C level was significantly lower in high concentration group than in normal and low concentration groups one month after operation (P＜0.05).Three months after operation,TG and FBG levels were significantly higher in high concentration group than in normal and low concentration groups (P＜0.05 and 0.01,respectively).Six months after operation,TC,TG and FBG levels were significantly higher in high concentration group than in normal and low concentration groups (P＜0.05,0.01 and 0.05,respectively).There was no significant difference between normal and low concentration groups in various biochemical indexes at any time point (P＞0.05).Conclusion The higher blood concentration of Tac and the longer used after renal transplantation,the easier it might cause drug-induced hyperlipidemia and diabetes.

Objective To investigate the efficacy of imatinib combining with allogeneic hematopioetic stem cell transplantation or chemotherapy for bcr-abl positive acute lymphoblastic leukemia (ALL). Methods 12 cases were diagnosed on morphology, cytochemistry, immunophenotype and bcr-abl fusion gene. The induction is imatinib (400 mg/d) combining chemotherapy. 8 cases accepted allogeneic hematopoietic stem cell transplantation after complete remission (CR). If bcr-abl became positive, the patient was treated with imatinib (400～600 mg/d). 3 cases were tested with imatinib alternating chemotherapy after cr. Results 11 patients gained CR, CR rate 91.7 %; 5 patients (41.7 %) became bcr-abl negative through 2 courses induction. 3 cases relapsed after transplantation. 2 cases relapsed in imatinib combining chemotherapy group. The median remission interval is 16 months (imatinib combining transplantation group) and 10 months (imatinib combining chemotherapy group) (P <0.01) respectively. The median survival time is 18 months (imatinib combining transplantation group), and the other group (imatinib combining chemotherapy) is 12 months (P <0.01). Conclusion Imatinib combining chemotherapy achieved high CR rate for the bcr-abl positive ALL. Imatinib combining allogeneic hematopoietic stem cell transplantation is superior to imatinib combining chemotherapy for CR patients.
