To establish a method for the determination of the content of total flavones and the quality control of Runchang Ningshen Extract. [Methods & Results]With rutin as control,the optimal concentration of Runchang Ningshen Extract was obtained by refluxing for three times with 70% ethanol.Ultraviolet spectrophotometry was used.The regression equation was induced at detecting wavelength being 511nm and with sodium nitrite and aluminium nitrate as color developing agent.There was a good linearity (r=0 9999)in the range of 8 ?g.The average recovery of total flavones was 94 63%(RSD=2 58%,n=5).[Conclusion]This method is simple and reproducible and can serve as the standard for controlling the quality of Runchang Ningshen Extract.

117 guinea pigs were divided into groups, receiving 1mg, 5mg, 50mg and 100mg Vit C per os daily respectively in 2-4 weeks. There were conducted four experiments: (1) the effect of different vitamin C levels on the cold tolerance and adaptation in guinea pigs; (2) effect of large dose of vitemin C on sudden and long time exposure to cold: (3) the action of vitamin C, in large dose and short time in combination with hormones, on cold tolerance of guinea pigs; (4) effect of large dose of vitamin C on the myocardial enzyme activity, during the process of cold adaptation. Rectal temperature, body weight, weight and vitamin C contents of adrenal glands, the excretion of urinary 17-Ketostero'ids, activity of myocardial succinic dehydrogenase and cytochrom C oxidase were observed. The results revealed that large dose of Vitamin C per os might lessen the lowering of rectal temperature and body weight after exposure to cold; promote the activities of myocardial enzymes. Better results were obtained with combination of vitamin C with cortisones. It was noted that large dose of vitamin C apparently increased and accelerated the tolerance and adaptation of organisms to cold.

The dietary composition of inhabitants of the endemic and nonendemic areas, the epidemics of Keshan disease, and its clinical examinations from 14 counties in Heilongjiang, Hebei, Shanxi, Shantong, Shanxi, Sichuan, Yunnan and Xizhang provinces were investigated.The results revealed: (1) There were differences of the dietary sources between endemic and non-endemic inhabitants (difference of water-soil conditions); (2) The composition of diet between inhabitants of endemic and non-endemic areas were different; (3) There were differences of dietary composition of the inhabitants between peak year of incidence and ordinary year in endemic districts. The less the variety of diet the higher the incidence of the disease; the greater the variety of diet, the lower its incidence. The decrease of the incidence was closely related to the improvement of dietary conditions in endemic area.

Basic fibroblast growth factor(bFGF) is one of the most important factors for wounds healing.BFGF promotes healing of bone fracture by regulating cell proliferation and differentiation of bone tissues,increasing local bone density,and accelerating local angiogenesis.With the progression of bFGF research,more and more attention will be paid to bone repair function of bFGF in bone tissue engineering.

Statins not only can help lower cholesterol,but also has certain effect for the treatment of malignant tumor.Its possible antitumor mechanisms include inducing apoptosis and differentiation,inhibiting tumor cell proliferation,reducing the invasion and metastasis of tumor cells,combined sensitization and chemical prevention effect.

ObjectiveTo study the diagnosis and therapy of circumcaval ureter.MethodsFifteen cases of circumcaval ureter were studied retrospectively.The cardinal symptoms include discomfort over the back and loins,nephrocolic and bloody urine.The diagnosis mainly depends on IVU and retrograde urography.12 patients underwent ureteroureterostomy,2 ureteropyeloneostomy and 1 nephrectomy.ResultsAll the patients have been follewed up from 1 to 15 years by IVU and ultrasonography,and no nephrohydrosis or stenosis of the anastomosis site has been noted.All the patients have been free from any complaints.ConclusionsIVU and retrograde urography are the cardinal means for the diagnosis of circumcaval ureter,and operation is indicated in order to improve the renal function.It is important to choose a proper time and an adequate surgical technique.

Th17 lymphocytes have been recently identified as a novel subset of CD4+ cells. It has been defined that IL-17,the main product of Th17, plays an important role in immunity against parasitic infection. There is a two-way influence between Th17 and cytokine network: on one hand Th17 consummates cytokine network, on the other hand many cytokines regulate Th17's activity in parasitic infection. In the anti-parasitic infection process, Th17 cells protect host or promote inflammation, even cause immune pathogenesis in different cases, which comprise host's immune state, the burden of parasitic infection, as well as the treatment.

Objective To compare the specificity and sensitivity of antibodies against cell membrane associated DNA (cmDNA)、 nucleosome (AnuA)、 double stranded DNA (dsDNA)、 deoxyribonucleoprotein (DNP) and antinuclear antibodies (ANA) in systemic lupus erythematosus (SLE). To analyze the relationship between these auto-antibodies in SLE. Methods One hundred and twenty five SLE patients and 118 other rheumatic diseases patients were studied. The latter included primary Sj?觟gren syndrome, ploymyositis, dermatomyositis, rheumatoid arthritis, osteoarthritis and systemic sclerosis. Indirect immunofluorescence was used to measure the anti-cmDNA antibodies and ANA. The enzyme-linked immunosorbent assay (ELISA) was used to measure the AnuA. Anti-DNP antibodies were detected by latex agglutination text and anti-dsDNA antibodies were detected by colloidal gold-technique. Results The seropositive rates of AnuA、 anti-cmDNA、 DNP、 dsDNA antibodies and ANA were 68%、 38.4%、 51.2%、 49.6% and 95.2% respectively in SLE patients. They were much higher than those of control groups (P

Hoechst 33342 is a kind of fluorescent dye used for evaluating the cell cycle and apoptosis in a variety of benign and malignant cell lines,such as BC3H-1 monocytes,HI-60 cells,HT-144 melanoma cells and hepatoma cells.The inhibitor of topoisomerase I,the alternation of TATA box binding protein.the intraeellular accumulation of E2F-l protein and the mitochondrial dysfunction may play an important roles in the apoptosis pathway indueed bv Hoechst 33342.
