Salsola collina is widely distributed in droughty and semi-droughty area, which is used as a kind of folk remedy in traditional Chinese medicine for treatment of hypertension. The study is on the chemical constituents of this herb from its aerial parts to obtain its active constituents. Dried and crushed aerial parts of this herb were extracted three times with 95% EtOH at reflux. The ethanol extracts were combined and concentrated under reduced pressure at 70 ℃ to yield residue, which was suspended in water and successively partitioned with light petroleum, chloroform and n-butanol. The chloroform and n-butanol fractions were treated by various chromatographic techniques, such as silica gel, C18 reversed-phase silica gel and macroporous resin column chromatography. Compounds were elucidated by their physicochemical properties and spectroscopic analysis. In the course of our study on searching biological active components from this herb, a new alkaloid together with three known alkaloids were isolated and identified as N-transferuloyl-3-methyldopamine (1), 3-[4-(β-D-glucopyranosyloxy)-3- methoxyphenyl]-N-[2-(4-hydroxyl-3-methoxyphenyl)ethyl]-2-propenamide (2), salsoline A (3), salsoline B (4). Compound 4 is a new compound and named as salsoline B, while compound 2 was obtained in Salsola collina for the first time.

Objective To evaluate the diagnostic evaluation of isotropic scanning and Lung Care soft- ware in solitary pulmonary nodules,and to improve the diagnostic accuracy.Methods 52 patients suffered from SPN were included in our study.Two experts in CT analyzed the films.First,they read the axial images and made diagnosis.Then isotropic scanning and lung care software approaches were used on 16 spiral CT and another analysis were made again.The results were compared with pathological diagnosis respectively. Results Spiculated sign,lobulated sign,vessel convergence were found more on isotropic scanning approach, that had significant difference with axial images analysis(P

Objective To study the relationship between renal morphology and renal function,and to assess the value of CT as a criterion to grade renal function.Methods Enhancement CT were performed in 89 patients with no local renal disease whose split renal glomerular filtration rates(GFR)were measured by renal dynamic imaging with ~(99)Tc~m-DTPA.The 178 kidneys were divided into normal renal function,mild and severe renal impairment groups according to renal function.Differences between three groups respect to the mean thickness of renal cortex and parenchyma were assessed by ANOVA.Using Pearson's correlation test,the correlation between the renal cortex,parenchyma thicknesses and renal GFR were examined.The value of CT in predicting renal function was assessed by using ROC analysis.Results The renal cortex thicknesses of normal renal function,mild and severe renal impairment groups were(5.9?1.1),(4.6? 1.1),and(3.3?1.0)mm respectively,and the renal parenchyma thicknesses were(26.3?4.2), (21.3?4.6),(16.2?4.6)mm.There were significant differences of renal cortex,parenchyma thicknesses between 3 groups(cortex F=54.78,P

Objective To compare the effects of every-other-day dose simvastatin administration with that of daily therapy of same dose.Methods This was a randomized,prospective,nonblinded clinical trial.The 186 patients with high low-density lipoproteim cholesterol(LDL-C) and/or high total cholesterol (TC),triglycerides (TG),low high-density lipoprotein cholesterol(HDL-C)was studied.All patients were randomized into two groups.The every-other-day do- sing group recerived 20mg of simvastatin in alternate-day and daily dosing group received 20mg of simvastatin every day.Before and after 6 weeks,12 weeks of treatment,serum lipoprotein,Live function tests and ereatine kinase con centra- tion and so on were drawn and bad-side effect were studies.Results The two groups significantly reduce LDL-C,TC, TG and a little increased HDL-C compared with baseline.No stalistically significant differences existed between the two groups in percentage in decrease in lipoprotain at 6 weeks,12 weeks compared with baseline.The bad-side effect in the two groups also had not a singnificant different.Conclusion The every-other-day dose of simvastatin have similar effi- cacious and safe to daily dosing in patients with hyperlipidemia and some cost savings.It can take a primary prevention to coronary heart disease in patients with relatively low-risk hyperlipidemia.

Objective To upregulate Notch signaling in cancer cells by overexpression of active part of Notch1 and to examine the proliferation of the cells. Methods Four cancer cell lines were infected with retrovirus recombined with sequence encoding active part of Notch1.CBF-1 reporter plasmid was used to detect Notch signaling and proliferation assay was carried out by MTS method.Cell cycle analysis was synchronously conducted. Results The overexpression of the active part of Notch1 induced upregulation of Notch signaling,led to growth inhibition in Hela and HepG2 cell lines and growth boost in BGC-823 cell lines,while had no effect on Chang cell lines. Conclusion The upregulation of Notch signaling can exert various effects on different cancer cell lines which is critical to the gene therapy for cancers.

Objective To discuss the relationship between thickness of RNFL and visual field, and its application in forensic identification. Methods Using the GDxVCC and Octopus automatic perimeter to check on 52 optic nerve lesion cases. The data is grouped according to valid value of visual field (Group1- severe injury group, Group2-minor injury group, Group3- slight and following slight injury group) , calculated for the averaged RNFL thickness, and analyzed by ANOVA. Meanwhile, the correlation between RNFL thickness and visual field indices(effective value of visual field, MD, MS, sLV) was analyzed with Pearson's correlation and described in scattered plot. Results Group 1 to 3 average RNFL thickness was 60.9036±9.53514μm, 53.6474±15.45306μm, 36.3±8.45695μm accordingly. Through ANOVA we can see that differences wer significant between every group. The valid value of visual field and MS were positively with the average RNFL thickness with a correlation of 0.543, 0.400, respectively(P<0.05). The MD and sLV were negatively correlated with the average RNFL thickness with correlation -0.450、-0.440, respectively(P<0.05). Linear relationship between the average RNFL thickness and effective value of visual field, MD, MS, sLV were Y=0.967X+19.508, Y=0.095X-10.858, Y=0.175X+9.187, Y=-0.205X+20.215accordingly. Nonlinear relationship between the average RNFL thickness and effective value of visual field, MD, MS, sLV were Y=-0.037X2+5.208X-93.795, Y=0.010X2-1.325X+50.111, Y=-0.008X2+1.103X-15.606, Y=0.004X2 -0.520X+22.232. Conclusion RNFL thickness measurement is expected to be an objective assessment in visual field, a new morphological methods.
