Objectives: To observe the effects and the mechanisms of exogenous fatty acids on colorectal cancer cells(LoVo). Methods:The effect of exogenous fatty acids on LoVo cells was determined by 5 diphenyl tetrazolium bromide(MTT) assay.The content of MDA was examined to evaluate the extent of lipid peroxidation. Results:The growth of LoVo cells was inhibited by polyunsaturated fatty acids(PUFAs).The inhibitory effect of saturated fatty acids and monounsaturated fatty acids on LoVo cells was not showed.None of the fatty acids was found to fibroblast cells(HLF).PUFAs caused the significant rising of intracellular MDA content. Conclusions:PUFAs could inhibit the growth of colorectal cancer cells.The strengthening of lipid peroxidation may be one of the mechanisms.

Objectives:To observe the changes in metabolism of fatty acids in breast cancer cells and the effects of inhibiting fatty acid synthase(FAS) on the growth of breast cancer cells. Methods:By RT PCR,the expression of FAS mRNA in breast cancer cell line was examined.The growth inhibition of breast cancer cells by specific FAS inhibitor, cerulenin, was determined by MTT assay.Flow cytometric analysis was used to study the changes of cell cycle. Results:FAS mRNA expression in MCF 7 cells was high.We found that cerulenin caused dose and time dependent inhibition of growth of MCF 7 cells.The growth inhibition of MCF 7 after 48 hours exposure of cerulenin at 2.5,5,10 and 20 mg/L was ( 43.47 ?4.58)%,(62.92?2.68)%,(81.93?0.91)% and (67.7?12.27)%( P

Objective To investigate the effect of excessive fluoride,aluminum on Zn,Fe,Ca,Mg,Cuin rat blood.Methods Forty eight SD rats were randomly divided into 4 groups matched with their weights:control group,high aluminum group,high fluorine group and high fluorine-aluminum group.Aluminum content in their drinking water was 0,90,0,90 mg/L respectively.Fluorine content of their feed was 5.2,5.2,106.0,106.0 mg/kg and aluminum Was 6.8,6.8,19.7,19.7 mg/kg respectively.90 days later,the level of blood Zn,Fe,Ca,Mg, Cu Was detected by the atomic absorption spectrometry.Results Compared among these groups,Zn,Fe,Mg and Cu content of the whole blood had significant difierences(F=46.25,14.74,6.10,2.93,P<0.05),while Ca content of the whole blood did not significantly change(F=2.81.P>0.05).Factorial analysis showed that excessive intake of aluminum could significantly decreased Zn,Fe,Mg content of the blood(F=42.66,5.41,7.04,P<0.05)and excessive intake of fluorine could significantly decreased Zn,Fe,Mg,Cu content of the blood(F=64.50,37.90,9.75,6.74, P<0.05).The coexistence offluorine and Muminum had interaction to the level of Zn(F=31.59,P<0.05)and did not obviously interact with other elements(F=0.91,1.63,1.51.0.00,P>0.05).Compared with the control group [(131.30 ±13.86)μmol/L,(10.24 ±1.02),(1.71 ±0.19)mmol/L,(20.43 ±4.42)μmol/L],Zn content in the high aluminum group[(90.84±9.98)μmol/L]decreased significantly(P<0.05),so did Zn,Fe,Mg content in tlle high fluorine group[(85.85 ±10.92)μmol/L,(8.49 ±0.68),(1.52 ±0.13)mmol/L],the difference being statistically significant(P<0.05)0Zn,Fe,Mg,Cu content in the high fluorine-aluminum group,being(82.82 ±11.00)μmol/L, (8.16±0.45),(1.46±0.09)mmoL/L,(15.69±2.38)μmol/L,respectively,all decreased signitlcarIdy(P<0.05). Compared with the high aluminum group[(9.43±1.09)mmol/L],Fe content of the high fluorine aluminum group[(8.16±0.45)mmol/L]decreased significantly(P<0.05).Conclusions Excessive fluoride can cause blood zn, Fe,Mg,Cu decline,so can excessive aluminum.Combination of excessive fluofine and aiuminum has 8ignificant synergic effect on the level of Zn but have rio influence on Ca.

OBJECTIVETo study the changes in the hippocampal volume in the acute phase after febrile convulsions (FC) in children.

METHODSThe brain MRI was performed on 30 children with FC (15 simple and 15 complex) and 30 normal children (control). The hippocampal volume for both sides was compared between groups.

RESULTSIn the control group, the average volume of the right hippocampus was significantly larger than that of the left side (P<0.05). There was no significant difference in the hippocampal volume between the left and right sides in the FC group. The average volumes of both the left and right hippocampus in the FC group (2.03 + or - 0.25 cm(3) and 2.18 + or - 0.21 cm(3) respectively) were enlarged compared to the control group (1.90 + or - 0.24 cm(3) and 1.97 + or - 0.20 cm(3) respectively) (P<0.05). There was no significant difference in the hippocampal volume between the simple and the complex FC groups.

CONCLUSIONSThe hippocampal volume is enlarged in the acute phase after FC in children. The hippocampal volume in children with simple FC is similar to that in children with complex FC in the acute stage.

Objective:To explore the operative indications, methods, curative effects and clinical prospect of Endovascular Graft Exclusion (EVGE) for descending thoracic aortic dissection (TAD). Methods:Under dynamic supervision of DSA, an EVGE with a stent graft complex of 130 44 mm was performed successfully on a 75 year old man with an aortic dissection (DeBakey ⅢB type). Results:Following the operation, DSA revealed that the intimal tear of the dissection was excluded by the endoluminal stent graft complex and the false lumen disappeared. The postoperative one week and one month, Duplex scan and CTA revealed that the stent graft complex was patent and had an inner diameter of 36 mm, without any migration and torsion. The false lumen of dissection was full of thrombi. The patient was discharged in a week. One month postoperative follow up showed that the patient was recovered to his usual normality. Conclusion:The indications for EVGE are DeBakey ⅢB type aortic dissections with the intimal tear, EVGE is a minus invasive method with a firmly curative effects, its clinical prospect will be very bright.
