Objective To evaluate the significance of ultrasonography in diagnosis and differentiation of morning glory syndrome. Methods Ultrasonography,CT and fundus fluorescein angiography(FFA) features were retrospectively analyzed in 6 cases of morning glory syndrome.Results Ultrasonography, CT and FFA characters of morning glory syndrome were as follow: on the B-type ultrasonogram, the dark area of vitreous cavity extended to the posterior pole and optic papilla, projecting to the basal part of muscle cones, thus the posterior part of vitreous cavity looked like a converted bottleneck. Sometimes the light ribbon of retinal detachment can also be seen. On the A-type ultrasonogram, both vitreous cavity and bottleneck showed no ultrasonic echo and acted as an equable baseline without any evident wave crest. The attachment spot of optic nerve of eye turned thin and vitreous body protruded to the posterior wall of eyeball with spherical shape on CT imaging. In the earlier period of FFA, hypofluorescence appeared on the optic disc; then ,the abnormal arteriae and vein around the optic papilla were diplayed clearly; In the later period, optic discs were dyed with fluorescein. Conclusions Ultrasonography, CT and FFA showed imageological features of morning glory syndrome from different aspects, which was helpful for differentiating similar diseases such as optic disc coloboma. Especially, ultrasonography was considered as a more safe and reliable imageological method than other imageological methods in precisely diagnosing and differentiating morning glory syndrome and superior to the traditional fundus check which gives no integrity.

Characters of one Candida intermedia yeast strain which isolated from nature can produce ethanol from xylose-fermenting been systemic studied. In conditions 28?C, 120 r/min, 72 h, it can produce 6.480 g/L ethanol from 7% xylose and 43.70% theoretical production of ethanol from 3% xylose. It can produce up to 21.225 g/L ethanol when incubation time prolong to 156 h from 8% xylose. It also can ferment 13% glucose produce 47.647 g/L ethanol and reach 76.90% of theoretical ethanol production, respectively. Compared to CK, ethanol productivity can be improved 9.91% when add 8% xylose in three times as 3%, 2% and 3%, respectively. Glucose can be first utilized in the mixture sugar medium. When the ratio of xylose vs. glucose is 3:1in mixture sugar, the productivity of ethanol can be improving 25%.

Objective To analyze the effects of different age and gender on the efficacy and pharmacokinetics of the target controlled infusion of atracurium besylate on liver dysfunction.Methods 160 case of patients with liver dysfunction and undergoing elective general anesthesia operation were divided into four groups according to their age and gender, 40 cases in each group:group A (age≥65 years old, male), group B (age≥65 years old, female), group C (age<65 years old, male), group D (age<65 years old, female).The patients received one-time double dose ED95 atracurium besylate, pharmacodynamic indexes and pharmacokinetic parameters were compared.Results The four groups of patients with block onset time, block maintenance time, clinical duration of T25%, in vivo role time T95%, muscle relaxation recovery index were compared, the difference was not statistically significant.The preoperative and postoperative 24h, four groups of patients with liver function ( alanine aminotransferase, aspartate aminotransferase, albumin, bilirubin) and renal function ( creatinine, urea nitrogen) were compared, the difference was not statistically significant.There was no significant difference between the four groups in the plasma concentrations of the substance to be measured, the peak time, the area under the curve and the elimination half lives.Conclusion For the patients with liver dysfunction, the target controlled infusion of atracurium besylate in general anesthesia operation, gender and age were not considered.

Objective To investigate the anti-proliferation mechanisms of Phenethyl isothiocyanate (PEITC)in human lung cancer cells line NCI-H446. Methods Human lung cancer cell line NCI-H446 was cultured in vitro,and treated with 10,30,50μmol/L PEITC for 24 h respectively. Cell viability and apoptosis were analyzed by methylthiazolyldiphenyl-tetrazolium bromide (MTT)assay and flow cytometry,respectively. Phosphorylation of Akt,activation of caspase-3 and caspase-9 in NCI-H446 cells,and production of cytochrome C in cytoplasm were detected by Western blot. Expression of phosphatase and tensin homologue (PTEN)was detected by real-time PCR. Results PEITC significantly reduced NCI-H446 cells proliferation in dose-dependent manner (P<0.05 ),and apoptosis was also inducted after PEITC administration. PEITC also markedly induced expression of caspase-3 and caspase-9,as compared with control group. And the level of cytochrome C in the cytoplasm was also increased after treatment with PEITC.Furthermore,PEITC treatment significantly increased the mRNA level of PTEN in NCI-H446 cells. Conclusion PEITC may be used as a potential anti-lung cancer agent by regulationg PI3K/AKT pathway and increasing PETN expression.
