The fragmentation pathways of two taxanes drugs have been studied in positive ion mode by Q-TOF with the advantages of high mass accuracy and high resolution analysis. The [M+H] + ions were observed by ESI-MS, from which the molecular weights were obtained. Using the protonated pseudo-molecular ions [M+H]+ as internal reference compounds, the accurate mass and element composition of the fragment ions were determined. The collision induced dissociation (CID) data of the [M+H] ions provided fragmentation pathways of related compounds. Results showed that the major cleavage pathways of paclitaxel and docetaxel were the same that the cleavage of C-O bond between the side chain and taxol skeleton easily occurred, then stripping of the functional groups on the parent ring. Some common fragments were formed, such as m/z 105.033 7, 291.137 3, 309.148 5, 327.159 7, 387.181 2 and 509.217 4, which would provide a basis for future qualitative and quantitative analysis of taxanes in vitro and in vivo.

Objective To study the effects of drug-containing serum of Ficus Hirta on oxidative damage of spleen lymphocyte due to aging in aged mice; To discuss its mechanism of action.Methods Forty aged mice were randomly divided into control group and high-, medium- and low-dose Ficus Hirta groups. Control group was given 0.9% sodium chloride solution for gavage, while high-, medium- and low-dose Ficus Hirta groups were given 6.6, 4.4, and 2.2 g/kg aqueous extract of Ficus Hirta for gavage. The spleen index was observed for optimum dose in aged mice. The optimum time and dilution of drug-containing serum of Ficus Hirta were confirmed by MTT method in lymphocyte proliferation test. The positive rate of senescent cells, the activity of T-SOD and the contents of MDA and ROS were determined in cellular antioxidant experiment after treated by optimal drug-containing serum for 48 h. Results Compared with the control group, the spleen index was significantly improved in high-, medium- and low-dose Ficus Hirta groups (P<0.05,P<0.01). 20% drug-containing serum of Ficus Hirta cultivated for 48 h had the best effects on lymphocyte proliferation in aged mice. 20% drug-containing serum of Ficus Hirta could significantly decrease the positive rate of senescent cells (P<0.01), improve T-SOD activity and decrease the contents of MDA and ROS (P<0.05,P<0.01).Conclusion The drug-containing serum of Ficus Hirta can improve the proliferative activity of spleen lymphocyte in aged mice and the mechanism of action may be involved in decreasing the positive rate of senescent cells and increasing antioxidant ability of lymphocyte.

Objective To discuss the value of the multi-b-value diffusion weighted imaging (DWI)in diagnosis of liver tuberculosis,abscess and atypical hydatid disease.Methods 23 patients with different liver lesions including abscess in 1 1,tuberculosis in 3 and alveolar hydatid in 9 were scanned with conventional MRI and multi-b-value DWI,and the imaging results were retrospectively analyzed.The ADC1 0b maps with 10 b values,three ADClow ones with low b values of 0 s/mm2 ,50 s/mm2 and 100 s/mm2 ,three ADChigh ones with high b values of 500 s/mm2 ,750 s/mm2 and 1 000 s/mm2 were gotten respectively.The ADCperf value was defined as a difference between ADClow and ADChigh values.Two regions of interest (ROI)with the same size were drawn in the liquefied region and mar-ginal area of the mass.The ADC values of ADClow ,ADChigh ,ADCperf and ADC1 0b maps were calculated and analyzed.Differences in b value and region among the three liver diseases were compared.Results The differences in ADC10b and ADChigh values between atypical liver hydatid and liver abscess in the liquefied region and marginal area were significant (P <0.05);the differences in ADC10b and ADCperf val-ues in the marginal area among liver tuberculosis,abscess and atypical hydatid were significant (P <0.05).The differences in ADCperf value in the liquefied region between thydatid disease and abscess,and in ADChigh value in marginal area between tuberculosis and abscess were not statistically significant (P >0.05).No differences in the ADClow value were found in both areas of three lesions (P >0.05). Conclusion Multi-b-value DWI and ADC maps and ADC values can provide valuable information in diagnosis and differentiation of liver tuberculosis,abscess and atypical hydatid disease.Different ADC values play more important role in the diagnosis of liver diseases.

Objective To assess the results of colonoscopy surveillance in 5 years after polypectomy of non-advanced colorectal adenoma and to identify its risk factors. Methods Patients undergoing colonosco-py and followed up with colonoscopy within 5 years between January 2003 and December 2013 were retro-spectively analyzed.No substance or only small quantity of clear water left in the intestinal tract and colono-scopes accessing ileocecus were regarded as complete examination. The initial colonoscopy was regarded as the baseline colonoscopy. Patients with non-advanced adenomas were assigned to the case group and those without were to the control group. Data of clinical characteristics and colorectal findings were estimated and risk factors were identified. Results A total of 828 patients were included,374 patients in the case group and 454 in the control group on baseline colonoscopy.The case group had a low incidence of advanced adeno-mas at a 1 to 5 years interval when compared with the control group,both with adequate baseline examination [1. 5%(5/ 326)VS 2. 2%(9/ 408),P = 0. 51]. The detection rates of advanced adenomas on follow-up colonoscopy at 1 to 3 years and 3 to 5 years in case group were 1. 7%(3/ 178)and 1. 4%(2/ 148),respec-tively(P>0. 05).Regression analysis showed age≥50 years old and being male were the independent risk factors for advanced adenomas recurrence within 5 years follow-up. No colon cancer was found in 828 patients during the follow-up. Conclusion Surveillance colonoscopy intervals within 5 years is of little benefit to pa-tients who had adequate polypectomy. Too early reexaminations due to concerns about advanced adenomas recurrence can be avoided.

Objective To evaluate whether the functional MRI could be used to reflect the change of angiogenesis after drug treat-ment,and obtain the related semi quantitative and quantitative parameters by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI).Methods The subcutaneous transplantation colorectal cancer were constructed in 20 nude mice,which were treated with Xiaoaifeimi.The transplanted tumor microvascular density,VEGF and PCNA were monitored.The therapeutic effect and MRI monitoring results were evaluated by combining DCE-MRI with the pharmacokinetic model.The semi quantitative and quantitative parameters were obtained for evaluating the effection of medicine.Half of nude mice were sacrificed to obtain the immunohistochem-ical staining.Correlation between pathological findings and parameters were analyzed.Results Compared to the control group,hu-man colon HT-29 cell proliferation rate was significantly decreased (44.87%)(P <0.05),and the apoptosis rate of HT-29 cells was increased 2.45 times (P <0.05)after Uyghur medicine treatment.The correlation between pathological examination and DCE-MRI parameters showed that Ktrans value and Kep were positively correlated with VEGF,MVD and PCNA (P <0.05).Conclusion A good relationship is showed between immunohistochemistry and DCE-MRI quantitative parameters in Uygur drug treating human colon cancer mice.
