Objective: To study the affection of Diallyl trisulfide on cultured human colon carcinoma cell line HT-29 and its mechanism. Methods: The viability of cells after various treatments were determined using the method of MTT. Flow cytometry were used to analyze the change of cell cycle and Bcl-2, Bax levels. Results: The proliferation of human colon carcinoma HT-29 cells were inhibited by Diallyl trisulfide. The inhibition was associated with dose and time dependence. Flow cytometry results showed that: 1) When cells were treated with Diallyl trisulfide at the concentration of 10 ?g/mL for 12 h and 24 h, the percentage of G0/G1 phase cells was decreased and that of G2/M phase cells was significantly increased compared with those in the control group.2) Diallyl trisulfide down regulated Bcl expression, while up-regulated bax expression. Conclusions: It was suggested that Diallyl trisulfide inhibited HT29 cell proliferation. And these were associated with arrest of cell cycles and down regulation of Bcl2/Bax ratio.

Objective Aliginic sodium diester(ASD) liposome was prepared and its aggregation stability was evaluated.Methods ASD liposome was made by reverse phase evaporating method from egg yolk lecithin,compared with blank liposome,the size distributions and mean particle diameters of ASD liposome and blank liposome were measured respectively before and after 40 hours heating under 37℃.Results Under the condition of n(PC)∶n(CHOL) = 1∶1,the mean size diameter of ASD liposome was 4.24?m.The mean size diameter of ASD liposome changed only 0.26?m after cultivation,however,the value of blank liposome was 1.35?m.Conclusion ASD loaded in the liposome enhanced the physical stability of the liposome.

Objective To evaluate the value of prenatal ultrasound in the interrupted aortic arch (IAA), and analyze the reasons of misdiagnosis and improve diagnostic ratio of this kind of defects. Methods Ultrasonic characteristics were analyzed in 16 fetuses with aortic arch anomalies, which were compared with ultrasound image and autopsy results of the normal fetus. The relativity of fetal IAA and abnormal chromosome was also analyzed. Results Among the 16 cases, 15 cases were confirmed by anatomy and the accuracy of ultrasound diagnosis was 94% (15/16), of which one case was serious constriction of aortic arch, one case was error type, three cases were obtained explicit type due to unsatisfactory results of prenatal ultrasound. The coincidence rate of ultrasonic type was 73% (11/15). All of the corrected diagnosed cases were detected with ventricular septal, of which 5 cases were detected with complete endocardial cushion defect, 9 cases were found extra cardiac malformations. Among the 7 karyotype check cases, 3 cases were diagnosed with Trisomy 18, 1 case Trisomy 13, while the rest 3 cases normal. The incidence rate of Trisomy 18 was 43 % (3/7). Conclusions Prenatal ultrasound shows a high accuracy in diagnosing fetal interrupted aortic arch (IAA ), but there’s a need to be improved in explicit typing. It is difficult to identify fetal interrupted aortic arch (IAA) and serious constriction of aortic arch (COA). The incidence rate of Trisomy 18 in the abnormal chromosome of fetal IAA is high.

Objective To investigate the in vitro susceptibility of Minocycline and polymycin B against clinical islates of pan-drug resistant Acinetobacter baumanii ,to provide laboratory support for clinical treatment for drug selection.Methods The susceptible test of Minocycline and polymycin against 39 isolates of pan-drug resistant Acinetobacter baumanii were determined by K-B meth-od.Results 38 strains of pan-resistant Acinetobacter baumanii were sensitive to polymyxin B,sensitive rate was 97.4%,20 strains sensitive to minocycline,the sensitivity rate was 51.3%.polymyxin B sensitivity was more sensitive than Minocycline (P < 0.05). Conclusion Polymycin B had strong activit ies against pan-drug resistant Acinetobacter baumanii .
