[ ABSTRACT] AIM:To study the effect of interleukin-1β( IL-1β) on neuron activation during the process of me-dial temporal lobe epilepsy ( MTLE ) .METHODS: IL-1β, rapamycin [ an inhibitor of mammalian target of rapamycin (mTOR)]and lentiviral transfection to knockdown PI3K-p85 were used to pre-treat the neurons.The protein levels of PI3K-p85, p-Akt, p-p70S6K and MAP2 were detected and the relationship among the tested cytokines was analyzed.The neuron endocytosis was observed in each group.RESULTS:IL-1βincreased the protein levels of PI3K-p85, p-Akt and p-p70S6K, up-regulated the expression of PI3K-p85 binding with IL-1RI in the neurons, and increased the neuron endocyto-sis compared with control group (P<0.05) .These processes were inhibited by rapamycin and silence of PI3K-p85 (P<0.05).Inhibition of the PI3K-p85 binding to IL-1RI decreased the protein levels of p-Akt, p-p70S6K and MAP2 which were increased by IL-1βstimulation (P<0.05).CONCLUSION: IL-1βactivates PI3K-p85 by binding with IL-1RI to promote the activation and proliferation of neuron synapses via PI3K/Akt/mTOR signaling pathway, which might be one of the mechanisms in MTLE chronic progress.

This study examined the effect of insulin on the expression of very low density lipoprotein receptor (VLDLR) subtypes of SGC7901 cells and discussed its biological implication. In vitro, moderately or poorly-differentiated human gastric adenocarcinoma cell line SGC7901 was incubated with insulin for different lengths of time, and then the expression of protein and RNA level in VLDLR subtypes were detected by Western blotting and real-time PCR, respectively. The results showed that, at certain time interval, insulin could down-regulate expression of type I VLDLR and up-regulate the expression of type II VLDLR in SGC7901 cells, at both protein and RNA level. We are led to conclude that insulin serves as a regulator in maintaining the balance between glucose and lipid metabolism in vivo, possibly through its effect on the differential expression of VLDLR subtypes.

To get high cell density,pH-stat fermentations of L.casei Zhang were carried out in the medium optimized previously under different cultural conditions.The influences of neutralizing agents,the concen-tration of buffer salts and glucose in the medium,pH,aeration and fed batch fermentation on the growth of L.casei Zhang were investigated.Based on the values of maximum specific growth rate,biomass and viable cells count in different cultural conditions,the optimal growth condition was regarded as follows:Glucose level of the medium was 80 g/L ～100 g/L;The pH was kept constant at 5.9 with aqua ammonia and anae-robic condition was kept by sparged with nitrogen periodically;The temperature was set at 37?C and cul-tured for 10 h ～12 h.The biomass and viable cells' number of L.casei Zhang under this culture conditions were 7 g/L and 3.5?1010 CFU/mL respectively,and were 7 times as high as that before optimized,which can meet the requirements of probiotics.

Conclusion A favorable clinical outcome can be achieved by titanium alloy steel artificial rib reconstruction of chest wall.

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.
