Serial analysis of gene expression (SAGE) is a powerful high-throughput experimental technique that allows rapid, quantitative analysis of global gene expression in eukaryotic organisms. A short sequence taq (10~14 bp),which is defined by an anchoring enzyme site at a fixed distance from polyA tail, contains sufficient information to iden-tify mRNA transcript from which it originates. The taqs are ligated to obtain concatemers that are cloned into a plasmid vector for sequencing. The identification and abundance of mRNA can be observed through bioinformatics and statistical analysis of a given tag. SAGE is not only applied in obtaining global profile of gene expression in a given cell or tissue, but also help identify a set of specific genes to the cellular conditions by comparing the profiles constructed for a pair of cells that are kept at different conditions. This review covers a general introduction of SAGE, its protocol, meth-odological evolution and applications in parasite biology.

Objective To investigate the effect of psychological intervention combined with gliclazide and sitagliptin on the treatment of poorly obese obese patients with type 2 diabetes mellitus. Methods 96 obese patients with type 2 diabetes mellitus who had poor control of blood glucose after insulin treatment were randomly divided into control group and experimental group,48 cases in each groups. Gliclazide and sitagliptin (FBG), glycosylated hemoglobin (HbA1c), 2h postprandial blood glucose (2hPG), fasting insulin (FIns) were measured before and after 15 weeks of treatment in the control group. situation. Results FBG, HbA1c, 2hPG and FIns were significantly lower in the experimental group than in the control group (P<0.05). Conclusion The combination of gliclazide and sitagliptin on the treatment of poorly obese type 2 diabetes mellitus with insulin treatment can significantly reduce the blood glucose level of patients and promote it.

Objective To discuss the relationship between various T lymphocyte subsets apoptosis and disease progression in chronic antiretroviral-naive HIV/AIDS patients. Methods Thirty-six chronic antiretrovi-ral-naive HIV-infected individuals as well as 16 healthy HIV-negative controls were performed in this study. Ac-cording to the CD4~+ T cell counts, all the patients were divided three groups: < 200/μl, 200-350/μl and > 350/μl. After the peripheral blood mononuclear cells(PBMC) were isolated, T lymphocyte subpopulations were determined by the expression of CD45RO and CD27, and the apoptosis of different T cell subsets were measured by Annexin V staining, then analyzed by flow cytometry. To investigate whether the apoptosis of T cells varied with the culture time in vitro, 4 healthy controls and 4 patients were chosen as subjects, and the lev-els of cell apoptosis were analyzed at the culture time points of 0, 3, 6, 12, 24 h. Results (1)The percenta-ges of the AnnexinV expression on CD4~+ and CD8~+ T cells and all the subsets in HIV/AIDS patients were sig-nificantly higher than that in the healthy controls (P<0.05), but there were no significant differences among the three HIV-infected patient groups(P>0.05). (2) No significant correlations were observed between the levels of apoptosis of all the T cells and subsets and total CD4~+ T cell counts(P>0.05) ,nor with the HIV viral load (P>0.05). (3)As the culture time prolonged in vitro, the levels of apoptosis and necrosis of CD4~6 T cells in HIV/AIDS patients were significantly higher than those in the healthy conlrols, and the CD4~+ T cells were more susceptible to apoptosis and necrosis compared with CD8~+ T cells. Conclusion The levels of T cell apoptosis in HIV/AIDS patients was significantly higher than those in the healthy controls, at the same time, CD4~+ T cells were more susceptible to apoptosis and necrosis compared with CD8~+ T cells, but no correlation was found between the T cell apoptsis and disease progression.

Hot-melt extrusion was applied to prepare mesoporous silica/ethylcellulose mini-matrix for sustained release, and fenofibrate was used as a model drug, ethylcellulose and xanthan gum were chosen as sustained-release agent and releasing moderator, respectively. This novel matrix obtained the controlled release ability by combining mesoporous silica drug delivery system and hot-melt extrusion technology. And mesoporous silica particle (SBA-15) was chosen as drug carrier to increase the dissolution rate of fenofibrate in this martix. Scanning electron microscope, transmission electron microscope, small angle X-ray powder diffraction and N2 adsorption-desorption were introduced to determine the particle morphology, particle size and pore structure of the synthesized SBA-15. The results showed that SBA-15 had a very high Brunauer-Emmett-Teller specific surface area, a narrow pore size distribution, large pore volume and a ordered two-dimensional hexagonal structure of p6mm symmetry. Differential scanning calorimetry and X-ray powder diffraction results demonstrated that fenofibrate dispersed in an amorphous state inside the pores of the mesoporous silica which contributed to the improvement in the dissolution rate. The drug release of mini-matrices was influenced by ethylcellulose viscosity grades and xanthan gum concentration, which increased with the increasing of xanthan gum concentration and decreasing of ethylcellulose viscosity. Mini-matrix containing 22% xanthan gum exhibited a good sustained release performance, and the drug release behavior followed the first-order kinetics.

Objective To investigate the effect of taurine transporter in the process of protection of brain edema in rats with severe traumatic head injury. Methods A total of 24 Male Sprague-Dawley rats were randomly divided into 4 groups. Except the control rats (Group Sham), all other three groups were subjected to lateral fluid percussion head injury. The TBI (Traumatic brain injury) models (Group TBI) and surgical control rats (Group Sham) were injected with saline through caudal vein after surgery, while the Taurine prevention and Taurine treatment models (Group Pre Tau and Group Tau) were injected with 120 g/L taurine solution before or after surgeries respectively. Water content in each brain, mRNA and protein expres?sion of aquaporin 4 and taurine transporter in the injured rat brain hemispheres were all evaluated over the time course of the study (7 d) in each group. Results Compared with rats in Group Sham, water content in each brain increase, mRNA tran?scription and protein expression of AQP4 were both up regulated but the mRNA transcription and protein expression of TauT were both down-regulated in rats in TBI group. Compared with rats in TBI group, brain water content, mRNA transcription and protein expression of AQP4 all decrease while mRNA transcription and protein expression of TauT all increase in rats in Pre tau and Tau groups. There is no statistical difference of TauT expression between rats in pre-tau group and Tau group. Conclusion Taurine exert its neuron protection role through draining water content from brain and down regulating expres?sion of AQP4 but rising expression of TauT after TBI.

Objective To study the effect of the levels of serum gonadal hormone and plasma calcitonin gene-related peptide(CGRP) on the hot flushes symptom of perimenopausal women. Methods 65 perimenopausal women (35 with hot flushes and 30 without hot flushes) and 25 healthy fertile women were enrolled. The subjects were analyzed for serum estradiol (E2), follicle-stimulating hormone (FSH) ,luteinizing hormone (LH) and plasma calcitonin gene-related peptide (CGRP). Results. ① There were no significant differences of the E2 levels between the perimenopausal women with and without hot flushes (P>0.05). The levels of FSH and LH were significantly higher in the women with hot flushes than women without hot flushes and fertile women(P<0.05),② The levels of plasma CGRP were significantly higher in the women with hot flushes than women without hot flushes (P<0.05), and significantly lower than fertile women,③The levels of plasma CGRP were significantly higher in severe hot flu-shes group than that in the mild hot flushes group and moderate hot flushes group(P<0.05), the severity of hot flu-shes was positively related to the level of plasma CGRP(rs=0.823, P<0.01), but there was no relationship be-tween serum E2 and the severity of hot flushes (P>0.05). Conclusion The occurrence of perimenopansal hot flu-shes might be closely related to the decline and fluctuation of serum E2,increase of FSH and LH and the concentra-tion variety of plasma CGRP.
