BACKGROUND: To search for an alloxenogeneic bone with good load bearing function and osteoblastic activity for treating bone defects is an important study issue. We have made a comparative study on its biome chanical characteristics and found that there was no significant difference in maximum load stress, maximum pressure as compared with fresh bone of the same size. Clinicians are concerned about the osteoblastic activity and whether the osteoblastic activity can be reserved after human allogenous a cellular bone (HAB) loaded with bone marrow stromal cells (BMSCs). OBJECTIVE: To investigate the experimental effect of HAB loaded with induced BMSCs, and observe the cellular adherence and growth as well as detect its osteoblastic activity. DESIGN: Single sample experiment. SETTING: Second Affiliated Hospital of Harbin Medical University. MATERIALS: This experiment was conducted at the Experimental Center of the Second Affiliated Hospital of Harbin Medical University between January 2003 and August 2004. HAB was obtained from fresh corpse iliac bones (donated voluntarily). METHODS: Connective tissues and cell compounds of the iliac bones were removed by processing with hydroperoxide andether solution and sterilized for preparing HAB. BMSCs from living femoral shaft bone marrow were cultured immediately in ordinary and mineralized medium containing DMEM, fetal bovine serum, dexomethasone, β-glycerophophate and ascor bic acid. Proliferation and differentiation of bone stromal cells were deter mined by detecting the level of alkaline phosphatase (ALP) and osteocalcin (OCN) in the culture medium. Induced bone stromal cells solution was condensed and implanted within HAB scaffold. Cellular osteoblastic activ ity was determined through morphological observation under the light mi croscope and electron microscope as well as biochemical index detection. MAIN OUTCOME MEASURES: ① Detection results of ALP and OCN of BMSCs/HAB composite. ② Histological observation results of BMSCs/ HAB composite. RESULTS: ① Iliac bone block cells were cleaned with good reservation of bone matrix. ② The level of ALP and OCN of MSCs was higher after in ducing for 8 days than that in control group [MSCs after induction: (181.54±40.01) nkat/L, (7.2±1.3) μg/L. There was no method to detect the level in control group, P ＜ 0.05]. ③ BMSCs were adhered and grew well in HAB scaffold. CONCLUSION: HAB loaded with induced BMSCs has an excellent os teogenic function in vitro and shows an effective potential as a good bone tissue engineering material.

Depression is a common emotional disorder that seriously affects people's life and health all over the world. The pathogenesis of depression is complex, and traditional Chinese medicine (TCM) for antidepressants has a good therapeutic effect because of its multi-component, multi-pathway, and multi-target action mode. At present, the anti-depressive mechanism of TCM has not been fully clarified, but it is clear that depression is closely related to metabolic health. Therefore, in order to further explore the anti-depressive mechanism of TCM, this paper proposes research strategies on the anti-depressive mechanism of TCM based on functional metabolomics from the perspective of metabolism, the potential biomarkers of depression are analyzed with the help of multi-omics combined analysis technology, and the functional molecules of TCM for antidepressant are studied. Molecular biology techniques are used to accurately capture the molecular interactions between biomarkers of depression and functional compounds, which identify effective drug targets and further elucidate the biochemical functions and related mechanisms involved in depression metabolic disorders. This paper systematically reviews the research strategies and applications of functional metabolomics in the anti-depressive mechanisms of TCM, expounds on the core value of functional metabolomics, and summarizes the current research status and hot issues of TCM for antidepressants in recent years, providing new methods and new ideas for the study of mechanisms of TCM with the help of functional metabolomics.

Objective This study was performed to investigate the effect of high mobility group box-1 protein (HMGB 1) on immune function of human T lymphocytes in vitro and explore its potential role in cell-mediated immune dysfunction.Methods Fresh blood was obtained from healthy adult volunteers and peripheral blood mononuclear cells (PBMCs) were isolated,then rhHMGB 1 was added to PBMCs.Four-color flow cytometric (FCM) analysis was used for the measurement of intracellular cytokine including interleukin Results (1) Different stimulating time and dosage of rhHMGB 1 did not alter the number of IFN-a positive cells (Th 1).rhHMGB 1 stimulation provoked a dose-dependent and time-dependent increase in Th2 subset and decrease in ratio of Th 1 to Th2.(2) Compared with the untreated cells,when the cells were coincubated with rhHMGB 1 (10-100ng/ml) for 12 hrs,protein release of IL-2 and sIL-2R were significantly up-regulated.At 48 hrs,in contrast,protein production was relatively lower in cells after exposure to 100-1000 ng/ml rhHMGBI.Conclusions These findings demonstrated that HMGB1 has a dual influence on immune functions of human T lymphocytes.

This study sought to investigate the in vivo antiviral effect of amantadine (AM) and biphenyl dimethyl dicarboxylate (DDB) on hepatitis B virus (HBV) in HBV replication mice. HBV replication-competent plasmid was transferred into male BALB/c mice by using hydrodynamics-based in vivo transfection procedure to develop HBV replication mouse model. The model mice were matched by body weigh, age and serum levels of hepatitis B e antigen (HBeAg) and were divided into four groups: AM group, DDB group, AM+DDB group and NS group, with the last one as control, and the mice of each group were administered corresponding agent orally twice a day, in a medication course lasting 3 d. On the third day, the mice were sacrificed 4-6 h after the last oral intake. HBV DNA replication intermediates in liver were analyzed by Southern blot hybridization. The serum hepatitis B surface antigen (HBsAg) and HBeAg were detected by enzyme linked immunosorbent assay (ELISA). Compared to the animals in the control group, HBV DNA replication intermediates in liver and HBsAg and HBeAg in serum from the AM and AM plus DDB group of mice decreased, and there was no difference between these two groups of mice. The levels of HBV DNA intermediate from liver and the serum HBsAg and HBeAg between the control and DDB group, however, were not obviously different. In conclusion, the inhibition effect of AM on HBV was detected, but treatment with DDB for 3 days did not influence the viral replication and expression of HBV in the HBV replication mice.
