To elucidate the signal transduction mechanism of systemic inflammatory response syndrome induced by LPS,Western blot analysis was used to assay the protein expression and phosphorylation levels of ERK, JNK,and p38 MAPK in murine KC which were stimulated by LPS. It was found that LPS treatment resulted in no significant change in their protein expression, but a rapid transient increase in their phosphorylation levels, which peaked at 30, 45,and 20 minutes,respectively; The values returned to mear baseline within 2 hours. Kinase phosphorylation levels of these three MAPKs induced by LPS were found to be dose dependent in a range of 10 pg/ml to 100ng/ml. No phosphorylation was observed in unstimulated cells. Among them, p38 MAPK shoned fastest and highest phosphorylation levels. The results show that LPS can markedly activate ERK, JNK,and p38 MAPK in KC, and p38 MAPK may play a more important role in LPS induced kupffer cell activation than ERR and JNK.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Objective To study the effect of fosinopril on the expression of NADPH oxidase subunit p22phox mRNA and the extracellular matrix (ECM) accumulation in the kidneys of rats with diabetes mellitus . Methods Diabetic rats induced by streptozotocin were randomly divided into control group(DM group) and fosinopril group (fosinopril 10 mg'kg-1·d-1) (DM+Fosin group) and treated for 12 weeks . Expression of p22phox mRNA of NADPH oxidase in kidneys was measured by RT-PCR . The expression of fibroneetin was studied by immunohistochemistry and matrix metalloproteinases 9 activity was detected by Zymography . Meanwhile, the kidney hypertrophy index, serum creatinine level and 24-hour urinary protein excretion were evaluated . Results The expression level of p22phox mRNA in the kidneys of DM+Fosin group rats was decreased by 45% than that of DM group at week 4 (P<0 .05) . At week 8 fosinopril significantly decreased the expression of glomerular and tubulointerstitial fibronectin by 52,5% and 42 .9% respectively (P<0 .05), while increased MMP-9 activity by 29 .6% (P<0 .05) compared with DM group . Fosinopril significantly decreased 24-hour urinary protein excretion of diabetic rats from week 8 . Serum creatinine level, 24-hour urinary protein excretion and kidney hypertrophy index were significantly decreased by 35 .9%, 50 .2% and 17 .2% in rats of DM+Fosin group than those of DM group at week 12 (P<0 .05) . Fosinopril did not affect blood sugar significantly . Conclusion Fosinopril has beneficial effect on diabetic nephropathy partly through inhibiting the expression of NADPH oxidase p22 phox mRNA .

Hypoxia-inducible factor(HIF) is an important transcript factor in sensing the concentration of O2 in cell and regulating the adaptation to hypoxia.HIF is consist of two subunits called ? and ? with ? as an oxygen-sensitive unit and ? as a constitutively expressed unit.The activity of HIF is regulated by both pVHL/proteasomal destruction system and non pVHL/proteasomal destruction system.Because the brain is the most oxygen-sensitive organ,use of HIF may be a potential application in treating cerebral ischemia disease.Yet HIF is reported to have both neuroprotective and proapoptotic functions in cerebral ischemia,which makes the application of HIF more complicated.This review will discuss the possible function and mechanism of HIF in cerebral ischemia,and the possible application of HIF to clinic.
