The elements in blood or serum, including calcium, magnesium, copper, zinc, chromium, manganese, nickel, selenium, lead and cadmium were determined in the normal and patients in Nanjing by atomic absorption spectrophotometry. The method used was proved to be reliable being checked by the reference bovine serum and the data obtained in this paper was coincident with those reported by the other authors previously. The relationship between the concentrations of elements and the ages as well as the sexes in the normal was discussed briefly. The concentrations of several of the elements of the patients were significantly different from those of the normal in the same ages.

Initiation of insulin therapy is challenging in the primary care setting without nursing support. Doctors have to prepare their practices to deal with these challenges in order not to delay insulin therapy when needed.

Objective:To investigate the antitumor efficiency of the special cytotoxic T lymphocytes(CTLs) activated by dendritic cells(DCs) pulsed with K-ras (12-Val) antigen.Methods:DCs was generated from PBMC in the presence of granuloceyte/macrophage-colony stimulating factor(GM-CSF),interleukin-4(IL-4)in vitro.DCs were differently sensitized with K-ras mutant pancreatic cancer cell line,K-ras(12-Val) mutant peptide,K-ras(12-Val) mutant peptide with the surface of cationic nanoparticle.Cell surface markers on DCs was measured by flow cytometry.The activation of CTL induced by DCs was detected by ~3H- thymidine incorporation test.The killing effects of CTL to pancreatic cancer was detected by ~(125)I-UdR release test. Production of IL-12 and IFN-γ by DCs and PBMC was detected by ELISA.Results:Compared with DCs pulsed with K-ras(12-Val) mutant peptide and K-ras (12-Val) mutant peptide with the surface of cationic nanoparticle,DCs pulsed with whole tumor antigen could better induce CTLs killing activity(P＜0.05).The DCs with K-ras(12-Val) mutant peptide and K-ras mutant peptide with the surface of cationic nanoparticle could produce specific CTL killing activity aganist pancreatic cancer cell line Patu8988(K-ras+)(P＜0.05),but not SW1990(K-ras-)(P＞0.05). K-ras (12-Val) mutant peptide with the surface of cationic nanoparticle at lower concentrations can be effectively presenting on the surface of DCs than only K-ras (12-Val) mutant peptide.Conclusion:K-ras (12-Val) mutant peptide with cationic carrier can be effectively presenting and expression of DCs and induce CTL specific killing activity aganist pancreatic cancer cell lines with K-ras (12-Val) mutant peptide.

Objective To study the effects of diabetes on hippocampal synaptic plasticity in perforant path-dentate gyrus pathway (PP-DG) in rats. Methods 70 SD rats( 180±20) g were divided into 3 groups at random: control group, type1 diabetes group (DM1)and type2 diabetes group (DM2). After Morris water maze test, 15 rats that showed worse spatial memory ability were selected in each model group to investigate the variation of paired-pulse facilitation (PPF) and the range of synaptic plasticity. Field potentials were recorded in the dentate gyrus of the dorsal hippocampus by stimulating the perforant path. Results Contrast to the control group, diabetic rats' hippocampal LTP were depressed (P<0.05), and type1 diabetic rats' LTP reduced much more. Diabetic rats' PPF ratio was reduced contrast to the control group (P<0.05). Conclusion Type1 and type2 diabetes impaired synaptic plasticity of hippocampal PP-DG pathway in rats, which conformed the results of water maze test.

Objective To investigate the clinical significance of serum amyloid A protein in patients with chronic hepatitis C (HCV) infection. Methods Serum amyloid A (SAA) levels were detected by ELISA in 131 patients with HCV infection and 20 normal controls. The expression of SAA-mRNA in peripheral blood mononuclear cells (PBMC) was detected by RT-PCR from some blood samples of HCV patients and normal controls. Results The SAA levels in the patients with chronic HCV infection were markedly higher than those in normal controls (t = 17. 14, P < 0. 01 ). The expression of SAA-mRNA detected by RT-PCR was closely correlated with concentrations of SAA measured by ELISA ( r = 0.86, P <0.01 ). No correlation was found between SAA expression and serum HCV RNA titers, as well as between SAA and serum ALT in patients with chronic HCV infection. Conclusion SAA levels are increased in patients with chronic HCV infection, which is not correlated with HCV RNA titers and serum ALT levels.
