Recently,the incidence of Alzheimer's disease has been significantly increasing.However,the pathogenesis of Alzheimer's disease remains unknown.It is presumed that insulin and insulin receptor may be involved in the pathogenesis of Alzheimer's disease.The relationship between insulin and cerebral glucose metabolism,the relationship between insulin,insulin receptor,insulin resistance and pathogenesis of Alzheimer's disease as well as the possible mechanism are reviewed in this paper,and the progress of treatment of AD is also described.

AIM: To elucidate the effects of platelet-activating factor (PAF) on eosinophil activation and the action of dexamethasone or theophylline during this process. METHODS: Eosinophils (EOS) from the peripheral blood of normal subjects were isolated. The hypodense eosinopil (HE) and normodense eosinophil (NE) were studied with electron microscopy. The effects of PAF on eosinophil activation and the action of dexamethasone or theophylline during the above process were measured. RESULTS: Hypodense eosinophil had significantly smaller individual granules than normodense eosinophil had. PAF induced eosinophil peroxidase release, and generated. Eosinophils incubated with 10~(-8) mmol/L PAF and 10~(-5) mmol/L dexamethasone released (101.17?10.32) mg/L eosinophil peroxidase (P

BACKGROUND: Based on the characteristics of cartilage tissue, such as consisting of single type of cells, the cartilage cells or chondrocyte, absence of blood vessel, rather low consumption level of oxygen and nutrition, low level of allo-immunocompetence and simple function in vivo, it seems to be easy for cartilage cell lines to be established for tissue and cell transplantation. We want to set up a cell line with the purpose of current use in tissue engineering in vitro. It will provide the basis for artificial tissue and organ that will become to be standardized and yielded in batch.OBJECTIVE: To explore the potential stimulatory effects of basic fibroblast growth factor(bFGF) and insulin on the proliferation and differentiation in primary culture mice chondrocytes in vitro. The effect and application of the cell factors will be evaluated for tissue engineering.DESIGN: A grouping controlled and repeated trial was conducted with the cells as the subjects.SETTING: Key laboratory of tissue transplantation and immunology of a college.MATERIAIS: The experiment was completed in the Key Laboratory of Tissue Transplantation and Immunology of the Ministry of Education, Jinan University from November 2002 to May 2003. Cultured cartilage cells at random were obtained as the study objects.METHODS: Mice cartilage cells were cultured in medium at the minimum concentrations of serum. The effects of different concentration of bFGF and insulin on the proliferation and differentiation in mice cartilage cells were observed with WST1 and immunofluorescence staining.MAIN OUTCOME MEASURES: Primary results: ① Effect of bFGF on proliferation of primary cultured mice cartilage cells. ② Effect of insulin on proliferation of primary cultured mice cartilage cells. Secondary results:morphological observation of cartilage cells RESULTS: Primary cultured mice cartilage cells were cultured in medium at the minimum concentration of serum(4 g/L fatal bovine serum). It was found that bFGF and insulin might play an important role on the proliferation and growth of mice cartilage cells in a dose-dependent manner. In addition, morphological observation of cartilage cells showed that both bFGF and insulin not only promoted the proliferation of the cells but also enhanced the matrix secretion of cartilage cells.CONCLUSION: Both bFGF and insulin can stimulate the proliferation of cartilage cells in vitro.

Objective To explore clinical practice value of Disease Severity Evaluation Scale (DSAS), and divide patient's nursing level according to the results of DSAS. Methods The assessment group was set up for evaluation of the scale, DSAS was used to determine the nursing level of 3 713 hospitalized patients (age > 18 years old) from 17 clinical departments, from April to May 2014. Results Nursing level determined by DSAS was compared with the standard nursing level, kappa coefficient was 0.72, P < 0.05, suggesting that the consistency was better. According to the kappa coefficient, 17 clinical departments could be divided into three categories, namely the applicability of DSAS were different in different departments. Conclusions DSAS can be used as a objective basis for division of nursing level and has a certain clinical significance. But in order to make it guide clinical work better, scoring system with department characteristic should be developed on the basis of DSAS.

Objective To explore a reliable method of 70% hepatectomy model in liver fibrosis mice. Methods Sixty-six C57BL6 mice were randomly devided into control group (n=6), the traditional group (n=30, ligation and removal liver lobe) and improved group (n=30, removal of liver lobe after blocking blood flow). Those 60 mice were induced liver fibrosis firstly, then randomly divided into six mice in each group, and were sacrificed at preoperative, 12, 24, 48 and 72 hours after liver resection. Liver tissues and blood samples were collected. The survival rate and incidence of complications were recorded and compared between two groups. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured to observe the liver injury after 70%hepatectomy. The ratio of liver weight to body weight and the expression of proliferating cell nuclear antigen (PCNA) were also measured to observe the difference of liver regeneration between the two groups. Results (1) Compared to the pathological control group, liver fibrosis model was established successfully in both traditional group and improved group, which can be used in 70%hepatectomy. So the follow-up experiment can be undertook timely. (2) Compared to traditional group, the survival rate was improved significantly in improved group (96.67%vs. 73.33%), and the incidence of complications was significantly lower (P<0.05). (3) The ALT and AST levels were higher 12 h and 24 h after operation in traditional group than those of improved group (P<0.05), while ALT and AST levels were increased first 12 h after operation and then decreased in both groups (P<0.05). (4) The liver/body weight ratio showed a decreasing trend 12 h after hepatectomy in two groups. The expression of PCNA increased at the beginning of postoperative, and reached its peak at 48 h (P<0.05). However, there was no significant difference at each time point between the two groups. Conclusion By blocking blood flow to establish 70% hepatectomy model in liver fibrosis mice, we can significantly improve the success rate of the model, and reduce the incidence of complications.

Objective:To understand the medication safety events about cephalosporin in our hospital in order to provide evidence for the better medication safety of cephalosporin. Methods:Adverse drug reaction ( ADR) reports, medication error ( ME) reports and drug quality problem records about cephalosporin in our hospital were collected and the critical indicators in the reports were analyzed. Re-sults:The ADR reports selected in our hospital were mainly reported by pharmacists. More males were involved in the related patients, and young adults were in the majority. Second and third-generation cephalosporin were the major drugs used in the reports. The damages in skin and its appendages were the major damages in organs. The ME reports selected in our hospital were totally reported by pharma-cists. Errors in frequency and dose of drug administration were the most common, and the main causes were lack of knowledge and train-ing. No serious quality problem in cephalosporin was found in our hospital, and the inner and outer packaging in damaged conditions was the most common problems in our records. Conclusion:Cephalosporin as one widely used antibacterial agent is considered safe and effec-tive. Because of its large amount of application, cephalosporin should be paid more attention by health care professionals. MEs should be avoided as far as possible. ADRs should be treated timely and properly in order to decrease medical disputes. More attention should be paid to ensure security of drug use for patients.

Objectives To analyze the relationship between phosphorylation of serine-3 of cofilin1 and Taxol resistance of ovarian cancer and to evaluate the prognostic value of cofilin1 phosphorylation in estimating ovarian cancer survival using clinical samples.Methods Wild type (WT) plasmids with over-expression of wild cofilin1,S3L plasmids with over-expression of cofilin1 and inhibited phosphorylation at serine-3,and siRNA-C plasmids with down-regulation of cofilin1 were constructed using molecular biology techniques.After the SKOV3 and SK-TR30 cell-lines were transfected with these plasmids,changes in biological characteristics and drug resistance after instant transfection were compared.Fifty-one elderly female patients with microscopically confirmed ovarian cancer,who had received chemotherapy with Taxol and cis-platinum (TC)after surgery,including 30 chemo-sensitive and 21 chemo-resistant cases,were recruited in this study.Immunohistochemical methods were used to detect the expression of cofilinl and phosphorylated cofilin in tissue sections from the two groups.Progression free survival(PFS)was analyzed.Results Compared with the control group,the proportion of cells increased at the G0/G1 phase(P=0.034)and decreased at the S phase (P=0.031),and the apoptosis rate decreased(P=0.020),in SKOV3 cells with high expression of cofilin1.However,these characteristics disappeared when the wild type was replaced with the inactive mutant S3L.When cofilin1 expression was down-regulated in SK-TR30 cells,the proportion of cells at the G0/G1 phase decreased(P=0.020).The expression of cofilin1 was detected in 56.7 ％ (17/30)and 57.1％ (12/21),respectively,sections of ovarian tumor tissues of the chemo-sensitive and chemoresistant groups,and there was no statistic difference (x2=0.332,P =0.943)between the two groups.The expression of phosphorylated cofilin was much higher in the chemo-resistant group (85.7％ or 18/21)than in the chemo-sensitive group (53.3％ or 16/30),and the difference was statistically significant(x2=5.829,P=0.016).The higher expression of phosphorylated cofilin was also correlated with shorter PFS(x2 =21.440,P＜0.01,95％ CI:0.068-0.883),especially in the chemo-sensitive group.Conclusions Serine-3 phosphorylation status of cofilin 1 is associated with paclitaxel resistance in ovarian cancer,but the underlying mechanisms of regulation need further investigation.
