AIM: To investigate the role of angiotensin II (Ang II)and Ang II receptor (Ang II R) in the ischemic injury of kidney.METHODS: The expression of renal Ang II type 1 receptor (AT 1R) gene in renovascular hypertensive rats was detected by reverse transcriptase-polymerase chain reaction (RT-PCR), and levels of Ang II in the kidney and plasma were examined by radioimmunoassay.RESULTS: The study showed that the contents of Ang II in plasma and renal tissue in experimental group were increased signifiantly ( P

Nanobacteria (NB) is a kind of new bacteria with a diameter of 8 0~500 nm. It has specific mineralizing ability. As a active nidus it can attac h, invade and damage the renal epithelium of collecting ducts and papilla, and t hen form apatite which being the center to induce formation of kidney stones. I n the paper, the research progress on nanobateria contained in kidney stones and its role in kidney stones formation were summarized. The simulation in vitro a nd animal models of kidney stones formation induced by nanobateria were discusse d.

OBJECTIVE: To explore the inner quality of two kinds of single decoction solution. METHODS: The methods of HPLC, UV, TLC etc. were used for the qualitative and quantitative analysis. RESULTS: The contents of main components in single decoction solution of herbs in granule form were higher than those in slice form- CONCLUSION: The decocting rate of herbs in granule form is higher. It is worth popularizing.

AIM: To develop a method for determining contents of ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 in Sanxue Mingmu Tablet(Radix et Rhizoma Notoginseng,Pheretima,Herba Leonuri,Rhizoma Imperatae,etc.). METHODS: The contents of ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 were separated by gradient elution on Hypersil ODS C_(18) column(5 ?m ? 4.6 mm?100 mm) as stationary phase;acetonitrile and water as gradient mixed mobile phase;detected at 203 nm wavelength;(25 ?C) of column temperature and 1.0 mL/min of mobile rate. RESULTS: Ginsenoside Rb_1,ginsenoside Rg_1 and notoginsenoside R_1 had good linearities(r=0.999 9;n=6) at the ranges of 1.480 0-14.800 ng;0.372 0-3.720 ng and 1.072 0-10.720 ng.The average recoveries were 98.44%(RSD=0.96%);99.02%(RSD=0.94%);97.95%(RSD=(1.02%)),respectively. CONCLUSION: This method is high in column efficiency and satisfactory for isolation and repeatability,the result is accurate.It can be adopted for quality control of Sanxue Mingmu Tablet.

Objective To determine the influence of stellate ganglion block on myocardial ischemial reperfusion arrhythmia.Methods Sixteen rabbits were divided randomly into two groups : group A(control group), group B (experimental group) was left lateral stellate ganglion blocks. Myocardial ischemia reperfusion model in vivo was carried out routinely. Blood samplies were taken from coronary sinus for the determination of neuropeptide(NPY) and noradrenaline(NE) at the following time point before LAD crossclamping , 5min, 30min after reperfusion.The occurrence of RA was measured in 1～5min during reperfusion.Results The level of plasma NPY and NE were significantly reduced at 5min, 30min after reperfusion (P

OBJECTIVE:To study the stability of Yinzhihuang injection(YZH) mixed with 5% glucose solution,10% glucose solution,glucose in normal saline,normal saline and Ringer's solution.METHODS:After YZH mixed with infusion fluid under room temperature,the contents of baicalin were determined with UV-spectrophotometry at different time periods within 24h,the apperance was observed,the pH values of baicalin were detected and identified by TLC.RESULTS:Under room temperature,after YZH mixed with Ringer's solution,the pH value of baicalin was markedly changed and a lot of white particles appeared;after YZH mixed with GNS,no changes of pH value and content of baicalin were found within 24h.When YZH mixed with other 3 kinds of infusion fluid,there were no changes in pH value and content of baicalin within 2h,however,in mixing with NS,the number of insoluble particles produced was beyond the standard.CONCLUSION:YZH should not be mixed with NS or Ringer's solution but it is compatible with 5%GS,10%GS and GNS,however,it should be mixed with them just before use and used up within 2h.

OBJECTIVE:To set up the quality standard for Xiaoyan San METHODS:Rheum officinale,Flos Lonicerae and Capejasmine were identified by TLC method The contents of emodin and chrysophanol in Xiaoyan San were determined by HPLC RESULTS:The linear range and average recovery of emodin was 21 12～105 6ng/ml(r=0 9 998,n=5) and 98 78%;The linear range and average recovery of chrysophanol were 29 28～146 4ng/ml(r=0 9 998,n=5) and 99 45% respectively CONCLUSION:The method is convenient,accurate and practicable It can be used for quality control in production of Xiaoyan San

OBJECTIVE:To compare the contents of hesperidin in raw Fructus Aurantii Immaturus and its processed products.METHODS:HPLC was used for the quantitative analysis of raw Fructus Aurantii Immaturus and its processed products.RESULTS:The content of hesperidin in vinegar-fried Fructus Aurantii Immaturus was the highest and that in the bran-fried Fructus Aurantii Immaturus was the lowest.CONCLUSION:It is suggested that there exist significant differences in intrinsic quality among various processed products of Fructus Aurantii Immaturus.
