Objective To study the correlation between anatomical measurement and CT measurement of adult occipital thickness so as to provide anatomic evidence for the selection of screw length in occipital-cervical fusion. Methods The occipital thickness was measured on the occipital specimens of 10 normal adults in two ways: direct anatomic measurement and CT measurement. Measurements were made on the basis of the McRac' s line and according to a matrix of 66 points following a grid with one cm spacing. The results of both measurements were statistically analyzed using SPSS 10.0. Results The results of both measurements were highly correlated. The external occipital protuberance was the thickest while the region of cerebellar fossa was the thinnest. The regions two cm lateral to the midline between plane Five and plane Six, one cm lateral to the midline between plane Four and at plane Five, and median between plane Three and plane Four were found to have a thickness of more than eight mm. Conclusions The occipital thickness varies with individuals. CT measurement and direct anatomic measurement are highly correlated. Preoperative CT measurements can be reliable evidence for optimal screw placement before performing occipital-cervical fusions.

Objective To study the effects of norepinephrine (NE) on intracellular reactive oxygen species (ROS) production in cardiac myocytes and receptor pathways involved in ROS production. Methods DCFHDA fluorescent probe was used for the assessment of NE induced intracellular ROS production in cultured cardiac myocytes of the neonatal rats. Myocytes were exposed to NE, NE + prazosin, NE + propranolol, and NE + prazosin + propranolol at different time and doses. The changes of fluorescence intensity in cells were measured by flow cytometry. Results NE increased myocyte ROS production in time and dose dependent manners. NE induced ROS production was partially inhibited by prazosin or propranolol, and completely inhibited by prazosin and propranolol together in myocytes. Conclusion NE can induce intracellular ROS production in cultured cardiac myocytes of the neonatal rats in time and dose dependent manners through the mediation of both ? and ? adrenoceptors.

This study was aimed to compare the function of dendritic cells (DCs) in patients of Y in-Huang syn-drome and Y ang-Huang syndrome from the peripheral blood of HBV related hepatic failure. Jaundice patients of HBV related hepatic failure were divided into two groups, which were the Y ang-Huang syndrome group and Y in-Huang syndrome group. And a healthy control group was also established. The DCs were separated and cultured in vitro from PBMCs in the peripheral blood. Surface molecules such as HLA-DR, CD80, CD86, CD83 and CD1αwere detected by the flow cytometry. And the level of IFN- α and IL-4 in the supernatant of DCs were also de-tected. The expression difference of inflammatory cytokines and immune cells between Y in-Huang and Y ang-Huang syndrome in patients of HBV related hepatic failure were compared. The results showed that compared with healthy people, the expression rate of DCs phenotype such as HLA-DR, CD1α, CD83, CD80, CD86 in patients of HBV related hepatic failure was significantly decreased (P < 0.01); the excreted factor IFN-α had a significant rising (P < 0.01). Compared to Y ang-Huang syndrome group, the expression rate of CD83 and CD86 in the Y in-Huang syndrome group of HBV related hepatic failure patients was significantly reduced (P < 0.01). And the ex-creted factor of IL-4 had a significant rising in Y in-Huang syndrome group (P < 0.01). Compared to the Y in-Huang syndrome group, the excreted factor IFN-α in the Yang-Huang syndrome group had a significant rising (P< 0.01). It was concluded that DCs function of patients with HBV related hepatic failure in both Y in-Huang syn-drome and Y ang-Huang syndrome group showed low immune function. And the immune function of the Y in-Huang syndrome group was lower. There was excessive releasing of inflammatory factors in the Y ang-Huang syn-drome group. And there was enhanced anti-inflammatory cytokine expression in the Y in-Huang group.
