It is consistent of the central monitoring server software, the Internet Explorer in the client PC, and a physiological signal collector. The server software can accept two client's request of data transfer, and real-time monitor several patients through Internet. The client uses the B/S mode, and just need to install an ActiveX control. The only thing users should to do is opening the Intemet Explorer, from which the waveform and signals are shown and transferred. The system extends the central monitoring service from hospital to the community, and is benefit for patient's long-term observation and cutting fees. Additionally, it can be a new solution of network based health care devices.

Objective To explore the key signaling pathways and molecules of bone sialoprotein (BSP) to promote proliferation and differentiation of preosteoclasts RAW264.7. Methods RAW264.7 cells were treated with BSP and the inhibitors of signaling pathway molecules. MTS and TRAP staining kits were used to evaluate the effects of proliferation and differentiation. The activity assay kits of Calcineurin, AKT, JNK, ERK and p38 were used to detect their activities. Results Inhibiting ERK and p38 can inhibit cell proliferation induced by BSP significantly, while inhibiting AKT, Calcineurin and PI3K can reduce the role of promoting the differentiation by BSP. With increasing treatment time of BSP, the activity of Calcineurin in RAW264.7 cells increased. Furthermore, the activity of AKT was maximum at 48 h after treated with BSP, while the activity of JNK, ERK and p38 were maximum at 24 h after treated with BSP. Conclusions BSP mainly regulates the ERK and p38 of MAPK pathway to promote RAW264.7 cell proliferation, and regulates AKT, PI3K and Calcineurin pathways to promote RAW264.7 cell differentiation.

AIM:To evaluate the effect of curcumin on impaired learning-memory ability and the expression of high mobility group box protein 1 ( HMGB1 ) and c-Jun N-terminal kinase ( JNK ) in a rat model of Alzheimer disease (AD).METHODS:Male Sprague-Dawley rats, weighing 250~270 g, were randomly divided into 4 groups (n=9):blank control group (group A), model group (group B), curcumin treatment group (group C, curcumin injected intraper-itoneally at 100 mg· kg-1· d-1 for 6 consecutive days) and solvent control group (group D).The rats of AD model were induced by injection of ibotenic acid into the nucleus basalis of Meynert ( NBM) bilaterally.All rats were trained in Morris maze to assess the ability of learning and memory .The expression of HMGB1 and JNK in the hippocampus was detected by the methods of immunohistochemistry and Western blotting .RESULTS:Compared with group A , the average escape laten-cy (AEL) in groups B and D were obviously longer (P<0.05), while AEL in group C in the 5th and 6th days were signif-icantly shorter (P<0.05).The releases of HMGB1 in the CA1 and CA3 areas in groups B and D from the nucleus were a-bundant.Compared with groups B and D , HMGB1 in hippocampal CA1 and CA3 areas in group C secreted out of the nu-cleus decreased obviously (P<0.05).No significant difference of the release of HMGB1 between group A and group C was observed (P>0.05).No significant difference in the expression of HMGB1 in the hippocampus among the 4 groups was found (P>0.05).However, compared with groups B and D , the expression of JNK in group C was decreased obvi-ously (P<0.05).CONCLUSION: Curcumin significantly improves the learning and memory ability of AD rats .The probable mechanisms may be related to inhibiting the release of HMGB 1 from the nucleus of hippocampal neurons and de-creasing the expression of JNK in the hippocampus .
