Comparative analysis of serum biochemical indexes of Uygur and Kazak adults of different ages and genders in Xinjiang / 解剖学报

Objective To analyze the changes of serum biochemical indexes with age and gender in Xinjiang Uygur and Kazak populations, and to compare the differences of serum biochemical indexes between Xinjiang Uygur and Kazak populations in gender and age. Methods Totally 511 Xinjiang Uygur and Kazak healthy adults were randomly selected from a hospital in Xinjiang Uygur autonomous region for normal physical examination, including 252 and 259 Xinjiang Uygur and Kazak healthy adults. Serum biochemical indexes were detected by CX-7 automatic biochemical analyzer produced by Beckman, USA, and statistical analysis was conducted by variance analysis, t test, correlation analysis and chi-square test. Results Xinjiang Uygur nationality and Kazak serum biochemical indexes for the male and the female, including glutamic-pyruvic transaminase (GPT), direct bilirubin (DBil), uric acid (UA), creatinine (Cre) and urea (Ure), glucose (Glu), total bilirubin(TBil), cystatin C(Cys-C) increased with the growth of the age, and sex between different age groups were statistically significant (P 0. 05). There were statistically significant differences in Glu, TG, TC, LDL and HDL between Xinjiang Uygur and Kazak people of the same gender and age group (P < 0. 05). Conclusion The serum biochemical indexes of Uygur and Kazak in Xinjiang are different in different ages and genders. The Glu and lipid levels of Uygur nationality in Xinjiang are different from those of Kazak nationality.

Effects of lipopolysaccharides of Bacterium prodigiosum on tumor growth and immunosuppression in mice / 南方医科大学学报

<p><b>OBJECTIVE</b>To observe the effects of lipopolysaccharides of Bacterium prodigiosum (BP-LPS) in inhibiting tumor growth and improving immunosuppression in mice.</p><p><b>METHODS</b>In mice bearing S180 tumor and a mouse model of immunosuppression induced by cyclophosphamide (CTX), the tumor growth, indexes of the immune organs and peripheral white blood cell count were measured after intraperitoneal injection of BP-LPS.</p><p><b>RESULTS</b>Injections of BP-LPS (40 U/kg) for 8 consecutive days resulted in a significant inhibition of the tumor growth in mice bearing S180 tumor (P<0.01), with a dose-dependent increase of the spleen indexes but no obvious changes in the thymus indexes. Intraperitoneal injections of BP-LPS for 7 days inhibited the reduction of peripheral white blood cells and spleen indexes in immunosuppressive mice, but did not produce any significant changes in normal mice.</p><p><b>CONCLUSION</b>BP-LPS can inhibit the tumor growth in tumor-bearing mice and enhance the immune functions of immunosuppressive mice.</p>

Studies on TLC fingerprint of flavonoids in rhizome of Polygonatum odoratum / 中国中药杂志

<p><b>OBJECTIVE</b>To study the thin layer chromatographic (TLC) fingerprint of flavonoid constituents from Polygonatum odoratum, to set up the identification protocol of the herbal and provide scientific information for its quality control.</p><p><b>METHOD</b>The ethanol extracts were separated on silica gel G precoated plate with a mixture of toluene-ethylacetate-formic acid (5:4:1) as the mobile phase. The spots were visualized with ammonia vapor, then were examined under ultraviolet light (365 nm). The plate was scanned at wavelengths of lambdaR = 500 nm, lambdaS = 280 nm.</p><p><b>RESULT</b>A fingerprint of flavonoids of P. odoratum, with 10 specific fluorescent spots while examined under ultraviolet light, was set up.</p><p><b>CONCLUSION</b>The method can be used for quality control of P. odoratum.</p>
