2. Synthesis of 1-(1H-1, 2, 4-triazole-1-yl)-2-(2, 4-difluoro-phenyl)-3-(N-cyclopropyl-N-substituted amino)-2-propanols and its antifungal activity
Academic Journal of Second Military Medical University 2010;29(11):1380-1383
Objective: To study the antifungal activity of triazole alcohols by introduction of cyclopropyl as side chain. Methods: Ten title compounds were synthesized and characterized by 1 HNMR,MS spectra and element analysis. The MICs of the compounds were determined by in vitro test in 8 fungus strains. Results: The title compounds exhibited potent antifungal activities against 8 strains,especially for the deep infection ones. Some compounds had MIC80 values less than 0.125 μg · ml-1 against Candida albicans, showing an activity 4 time higher than that of fluconzole. Conclusion: The title compounds with cyclopropyl and alky substituents have antifungal activities,and the antifungal activity decreases as the alkyl side chains getting longer.

Objective To have knowledge of the exact cause of massive osteolysis. Methods Hair of patients from Xinjiang province was collected and 14 trace elements were determined by inductively coupled plasma mass spectrometryICP-MS. Results Trace elements imbalance in the body of patients was disturbed. Chromium and zinc which are benefit to the growth of the bones were only 0.5 ?g/g and 40 ?g/g respectively that were much lower compared with the healthy persons cadmium was much higher than the limit level in healthy person. Moreover the quantity and ratio of potassium and sodium in the patients were obvious abnormal. Conclusion According to the result of the present paper may be the environmental and dietary factors play an important role in pathogenesis of this disease.

Tanshinones, the main bioactive compounds of Salvia miltiorrhiza, are the diterpenoid pigments, multiple genes were proved to be involved in their biosynthesis in plants. CYP76AH1 is the initial P450 gene in the tanshinones biosynthetic pathway, its function has been validated by yeast expression and in vitroenzymatic reaction. In order to clarify the function of CYP76AH1 in vivo, in this study, we constructedthe RNA interference of CYP7AH1 in S. miltiorrhiza hairy root. The RNA interference vector with a hairpin structure was constructed using the Gateway technology, and then the interference fragment was integrated into the genome of S. miltiorrhiza mediated by Agrobacterium rhizogenes. Several highly CYP76AH1 interference S. miltiorrhiza hairy roots were obtained for further analysis.

Astragalus adsurgens seed is one of the most common adulterants of Astragali Complanati Semen in the market, whose morphological characteristics are very similar with A. complanatus seeds (Astragali Complanati Semen). Many identification methods have been reported, such as morphological identification, fluorescence method, ultraviolet spectrophotometry, TLC, HPLC, protein electrophoresis and so on, but there's no much about microscopic identification. In the present study, the morphological characteristics and microscopic characteristics of these two seeds were investigated, which could provide scientific evidence for the identification and classification of Astragali Complanati Semen. Our results showed that these two seeds were slightly different in the color and the appearance, but significantly different in the microstructure of the seed coat and the hilum, and the distribution of fat droplets in the cotyledon cells. So these microscopic characteristics can be applied for the identification of Astragali Complanati Semen.

OBJECTIVETo explore the efficacy of Tuina for postpartum lactation and work out a optimal protocol involved.
METHODSWith a randomized, controlled and clinical method, 84 primiparas were divided into a Tuina group and a control group. While patients in the control group received rooming-in conventional managements, those in the Tuina group were additionally treated with Tuina, including local manipulations on breasts combined with acupoint manipulations. The colostrum-time, lactation quantity and prolactin were observed to make the comparisons between two groups.
RESULTSThe scores of lactation quantity after 1th, 2nd, 3rd of the treatment were 1.660 +/- 0.785, 2.530 +/- 1.030, 2.880 +/- 1.171 in Tuina group and 1.270 +/- 0.533, 1.460 +/- 0.811, 1.500 +/- 0.583 in control group respectively, where there were significant differences in each time stage between two groups (all P < 0.001). The time of colostrum was (21.6 6 +/- 10.508) h in the Tuina group and (22.5 +/- 9.762) h in the control group, in which the difference was not statistically significant (P > 0.05). The levels of prolactin (314.35 +/- 110.37) ng/mL and (321.56 +/- 109.61) ng/mL in Tuina group, (385.78 +/- 85.19) ng/mL and (340.12 +/- 103.10) ng/mL in control group before and after treatment, there were no significant differences (both P > 0.05).
CONCLUSIONPostpartum Tuina on breasts could increase the quantity of lactation and delay the decreasing of the levels of prolactin, which contributes primiparas to lactate more and sooner.
