The transesterification reaction conditions of lard with methyl acetate with combined use of immobilized lipases as catalysts were conducted. Initially, according to single factorial experiments, the studies on Lipozyme TL IM and Novozym 435 respectively catalyzed transesterification of lard showed that the optimal parameters of transesterification reaction were: the molar ratio of methyl acetate to oil of 14∶1, 40% enzyme added based on oil weight, temperature 50℃. Combined use of Lipozyme TL IM and Novozym 435 was proposed further to improve the catalytic performance by the response surface method (RSM). Herein, a 5-level-3-factor central composite rotated design was employed to evaluate the effects of lipase loading, the proportion of the two lipases and amount of methyl acetate. The optimum conditions were as followings: 40% lipase loading based on oil weight, 50%/50% the proportion of lipases (Novozym 435/Lipozyme TL IM), and the molar ratio of methyl acetate to oil of 14∶1. And under the optimal conditions, the highest biodiesel yield of 97.6% could be attained, which was higher than the biodiesel yield with each single one of the two lipases. The results suggested that the technics of combined use of certain immobilized lipases catalyzed transesterification reaction of lard for biodiesel production with methyl acetate as the acyl acceptor could raise the FAME yield and save the production cost.

Objective To explore clinical value of transvagiTIa ultrasound in diagnosis of cctopie oviductpregnancy.Methods EUB-2000 ultrasound diagnosis meter was used,the vagina probe head frequency is 5～10MHz,after the vagina to the womb,the double-side ovary,the double side oviduct and its periphery organizes to carry on omni-direetionally sweeps looks up.Results Transvagina ultrasound diagnosis ectopic pregnancy center oviduct pot abdomen pregnancy 158 cases,the oviduct canyon department 4 cases,between the oviduct the nature department pregnancy 2 cases,all pass through the cefioseope of our hospital.Coincidence rate was 100%.Conclusion Transvagina ultrasound diagnosis ectopie pregnancy is one of most accurate ultrasound diagnosis methods presendy,suggested various basic units hospital widely develops.

Objective To compare the effect of difierent combinatio of mannitol, furesemide and albumin in reducing intracranial pressure in 451 patients with severe traumatic brain injury (sTBI). Methods A total of 451 patients with an admissiou Glasgow Coma Scale of or less from 5 medical centers were randomly divided into 5 groups, ie, Group A(250 ml 20% mannitol each time as control), Group B(125 ml 20% mannitol each time), Group C(alternate use of 250 ml 20% mannitol each time or 40 mg furosemide), Group D(alternate use of 125 ml 20% mannitol each time and 20 mg furosemide)and Group E(alternate use of 125 ml 20% mannitol and moderate or large dose of albumin). We monitored intracraniai pressure continuously and observed the changes of intracranial pressure, electrolytes, hemato-crit and renal function after use of 5 combinations of mannitol. Furosemide and albumin. Results Man-nitol and furosemide could independently reduce intracranial pressure after 1-3 hours (P<0. 05). Semis mannitol plus furosemide or albumin could more signifieantly reduce intracranial pressure, with statistical difference compared with full dose of mannitol. Semis mannitol and alternate use of mannitol and furose-mide in aspect of intracranial pressure reduction and persistence time(P<0. 05). Alternate use of man-nitol and furosemide begot higher incidence rate of electrolyte abnormality, compared with the other com-binations (P<0. 05). Rebound rate of intracranial pressure was higher in full dose of mannitol than other combinations (P<0. 05). Incidence of renal function abnormality was higher in combination involved al-bumin than alternative use of mannitol and furosemide as well as combination of semis mannitol and furo-semide (P<0. 05). Abnormality of electrolyte and renal function wag reversible. Conclusion The use of 125 ml 20% mannitol each time plus 20 mg furesemide is more reasonable than other combina-tions. Meanwhile, semis mannitol combined with moderate or large dose of albumin has certain advantages too.
