ABSTRACT
Objective To evaluate the safety and effectiveness of conscious sedation and intravenous anesthesia used to endoscopic retrograde cholangio pancreatiography (ERCP) in treatment of extrahepatic bile duct stones.Methods A total of 100 cases of extrahepatic bile duct stones patients in treatment of ERCP were encoded by the group order,50 cases of odd used intravenous anesthesia (intravenous anesthesia group),intravenous injection of propofol; 50 cases of even used conscious sedation (conscious sedation group),muscle injection of diazepam and pethidine.Intraoperative reaction (extubation behavior,own postural changes),changes in vital signs,operating time,the success rate of stone and complication were observed in two groups.Results The incidence of intraoperative extubation behavior and own postural changes in conscious sedation group were significantly higher than those in intravenous anesthesia group [24％ (12/50) vs.2％ (1/50),18％ (9/50) vs.0],and the differences were statistically significant (P ＜ 0.01).The heart rate and mean artery pressure in two groups were decreased at 5 minutes after administration than that before operation,and the difference was statistically significant (P ＜ 0.05),but there was no statistical significance at 10 min after entering the mirror and postoperative awake compared with before operation (P ＞ 0.05).Pulse oxygen saturation between two groups had no statistical significance (P ＞0.05).The success rate of stone in two groups were 98％ (49/50).Operating time in intravenous anesthesia group was obviously shorter than that in conscious sedation group [(38.2 ± 6.3) min vs.(49.1 ± 9.9) min] (P ＜ 0.01).The complications between two groups had no statistical significance (P ＞ 0.05).Conclusion Conscious sedation and intravenous anesthesia can be used to ERCP in treatment of extrahepatic bile duct stones,but intravenous anesthesia can obviously reduce patients discomfort,shorten the operation time.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the chemical components in Baishao and Chishao water extracts and investigate their effects on the proliferation of rat thoracic aorta smooth muscle cells in vitro.</p><p><b>METHODS</b>The contents and chemical structures of monomers separated from the water extracts of Baishao and Chishao were analyzed using high-performance liquid chromatography and mass spectroscopy. Rat thoracic aorta smooth muscle cell line A7r5 and its platelet-derived growth factor-BB (PDGF-BB)-induced proliferation model were exposed to different concentrations of Baishao and Chishao water extracts, and the cell viability was analyzed by mitochondrial-dependent reduction of MTT and real-time cell analyzer.</p><p><b>RESULTS</b>The growth of A7r5 cells was significantly stimulated by 300 µg/ml Baishao water extract (P<0.01), but Chishao water extract produced no such effect (P>0.05). In PDGF-BB-induced cell proliferation model, the cell growth was significantly suppressed by 100-500 µg/ml Chishao water extract (P<0.01), while Baishao water extract showed no obvious effect on the cell proliferation (P>0.05).</p><p><b>CONCLUSION</b>Baishao and Chishao water extracts have different chemical components and produce different biological effects.</p>

In this study, an analytical method was developed and used to quantify simultaneously protocatechuic acid, neochlorogenic acid, cryptochlorogenic acid and 1, 3-dicaffeoylquinic acid--four bioactive compounds contained in Fructus Xanthii using UPLC. The contents of four phenolic components of 28 batches of samples collected from different product areas and markets were determined and compared by means of this established method. The mobile phase was composed of methanol and water containing 0.1% phosphoric acid. Chromatography was monitored at dual-wavelengths--220 and 327 nm. Flow rate was 0.4 mL x min(-1) and column temperature was 35 degrees C. The correlation coefficient between concentration and chromatographic peak area of protocatechuic acid, neochlorogenic acid, cryptochlorogenic acid and 1, 3-dicaffeoylquinic acid was over 0.9999 in the range of 0.3570-35.70, 2.500-250.0, 1.060-106.1, 1.010-101.0 microg x mL(-1), respectively. The average recoveries of the four compounds were 97.68%, 99.55%, 97.92% and 100.4%, respectively. In conclusion, the established method can rapidly attain an accurate and reproducible result used to control the quality of Fructus Xanthii.
