Objective: To investigate the effects of DATS (diallyl trisulfide) on cell proliferation, cell cycle and apoptosis of human osteosarcoma cell line Saos-2, and to explore their potential molecular mechanisms. Methods: Saos-2 cells were treated with 25, 50 and 100 μmol/L DATS for 24, 48, 72, and 96 h. The change of cell morphology was observed under an inverted microscope. The effect of DATS on the proliferation of Saos-2 cells was detected by MTT assay. After treatment with DATS at desired concentrations for various time intervals, the cell cycle and apoptotic rate of Saos-2 cells were analyzed by flow cytometry. The expressions of DATS-sensitive proteins in Saos-2 cells were systematically detected using 2-DE (two-dimensional gel electrophoresis) and mass spectrometry analysis. Results: DATS could inhibit the proliferation of Saos-2 cells in a dose- and time-dependent manner. Moreover, DATS could arrest the cell cycle at phase G0/G1 and induce the apoptosis in a time- and concentrationdependent manner. A total of 27 unique DATS-sensitive proteins, including 18 downregulated proteins and 9 upregulated proteins, were found in Saos-2 cells. Conclusion: DATS can suppress the proliferation of Saos-2 cells by blocking cell cycle progression and inducing apoptosis. The results of proteomics not only suggest the anticarcinogenic mechanism of DATS, but also provide a novel insight into the therapeutic targets for gene therapy of osteosarcoma.

Objective:To observe the curative effects and the influences of Yueanxin injection (YAXI, 悦安欣注射液) on acute cerebral infarction (ACI) and on blood rheology separately. Methods:Sixtytwo cases with ACI were randomly divided into treated group ( n=31) which was treated with YAXI and control group (n=31) which treated with tetrameth ylp yrazine injection (川芎嗪注射液) as control. Once a day for 30 days as a therape utic course to both groups.The curative effects and the changes in blood rheology parameter s were observed.Results:The marked effective rate (74.2%) and total effective rate (96.8%) in treated g roup were significantly superior to those (38.7% and 67.7% respectively) in cont rol group (P<0.05 or P<0.01). The improvements of blood rheology param eters in tr eated group were significantly better than those in control group (P<0.0 5 or P<0.01).Conclusions:The curative effects of YAXI on ACI are sufficient.

Objective To study the epidemiological characteristics of measles in Fuyong Street in order to predict its occurrence and reduce its incidence by establishing preventive and control measures.Methods Epidemiological data in Fuyong Street between 2003 and 2007 were analyzed.Results The result showed that 393 measles cases were reported in the whole street during 2003 and 2007,329 were confirmed by laboratory,and 60 were local cases.The measles annual average incidence was 18.29/100 000.The high incidence period was from March to August and the most measles cases were young adults and infants.30.79% cases had no immunization history and 24.68% cases had immunization history.Conclusions The incidence of measles is kept at a high level.It will go on possibly for half a year or a year.A comprehensive control measures should be thaken to strengthen vaccination program especially for foreign people and to reinforce the surveillance and analysis of epidemic situation in order to avoid the outbreak of the disease.

A simple and convenient procedure for stereoselective synthesis of (Z)-allyl selenides has been developed by a one-pot reaction of diselenides with Baylis-Hillman adducts in the presence of samarium metal-trimethylsilyl chloride under mild conditions. Presumably, the diselenides are cleaved by Sm/TMSCl system to form selenide anions, which then undergo S(N)2' substitution of Baylis-Hillman adducts to produce the (Z)-allyl selenides.

By non-steady method,the effective diffusivity of ferrous sulphate within alginate calcium gel entrapped without bacteria was measured.Meanwhile the oxidation ability of entrapped bacteria was analyzed.Experimental results showed that the effective diffusion coefficient of ferrous sulphate decreased with the increase of alginate concentration,the optimum alginate concentration is 2%(W/V).The effect of calcium chloride on the effective diffusivity was neglectable.The incubation of ferrooxidans would pass through 10 hours,and the diffusion coefficient within gel entrapped Thiobacillus ferrooxidans cells was less remarkably than that of ferrous sulphate without entrapped cells.For the entrapped cells,the absolute oxidation time was shortest and the rate change was fastest with the initial Fe concentration 5g/L.The absolute oxidation time was same when the initial Fe concentration was 8g/L and 10g/L.

Objective To investigate the clinical significance of external obturation with cotton ball in treatment of digestive tract lip shape fistula. Methods A prospevtive randomixed controllde study was conducted in 30 patients with digestive tract lip shape fistula admitted from January 2001 to November 2007,which were divided into experimental group ( 15 patienets) and control griup ( 15 patjients). The control group received traditional fistula mouth continuous drainage,with fastomg or part enteral nutrition and parenteral nutrition. The experimernal group received external obturatiion with cotton ball,with controling spills of oineteatinal fluid and resuming normal eating and activetes, The patients general information, fistuala mouth sixe, volume, weight, albumin, determinstic operation time, postoperative complications, hospital, signficantly reduced fistula, flow, postoperative compared between the two groups. Results Compared with the control group , significantly redced fistula, flow, postoperative complivations and cost, increased wdighe and albumin,as well as shortened operation time and hospital stay were found oin the experimetal grou. Conclusin External obturation with cotton ball is safe effective methde in treatment of digestive tract lip shape fistula, obviusly shortening the course of disease, redcing patients'cost and pain, and rapidly improving patients nutritional status.

Identification accuracy of traditional Chinese medicine is crucial for the traditional Chinese medicine research, production and application. DNA barcoding based on the mitochondrial gene coding for cytochrome c oxidase subunit I (COI), are more and more used for identification of traditional Chinese medicine. Using universal barcoding primers to sequence, we discussed the feasibility of DNA barcoding method for identification commonly-used medicinal snakes (a total of 109 samples belonging to 19 species 15 genera 6 families). The phylogenetic trees using Neighbor-joining were constructed. The results indicated that the mean content of G + C(46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the mean intraspecies genetic distance of Trimeresurus albolabris, Ptyas dhumnades and Lycodon rufozonatus was greater than 2%. Further phylogenetic relationship results suggested that identification of one sample of T. albolabris was erroneous. The identification of some samples of P. dhumnades was also not correct, namely originally P. korros was identified as P. dhumnades. Factors influence on intraspecific genetic distance difference of L. rufozonatus need to be studied further. Therefore, DNA barcoding for identification of medicinal snakes is feasible, and greatly complements the morphological classification method. It is necessary to further study in identification of traditional Chinese medicine.
