ABSTRACT
Objectives To provide scientific basis for the quality control of different species of Baishouwu by establishing the HPLC fingerprint of domestic of Baishouwu and determining the main active components of acetophenones. Methods HPLC-DAD method was used to determine the HPLC fingerprints of domestic of Baishouwu. Then, the content of 4 kinds of acetophenones in Baishouwu was determined. The column was Diamonsil C18（250mm×4.6mm, 5μm）with the mobile phase of methanol and 0.1% phosphoric acid at a flow rate of 1.0 ml/min. The detection wavelength of p-Hydroxyl acetophenone, baishouwu benzophenone, 2',4'-Dihydroxy acetophenone was set at 260 nm and 2',5'-Dihydroxy acetophenone at 280 nm respectively. Results The similarity and cluster analysis in HPLC fingerprint showed that the constituents were significantly different among C. bungei, C. auriculatum and C. wilfordii. The content of total acetophenones in C. wilfordii was significantly higher than that in other localities of C. auriculatum and C. bungei. Conclusions Acetophenone could be used as the evaluation index to evaluate the quality of Baishouwu in different origins. The content of total acetophenone in C. wilfordii is the highest, which could be used as the best quality resource of Baishouwu.
ABSTRACT
A set of comprehensive chemical experiments was designed for the second-year undergraduate majoring in pharmacy which contained synthesis,refinement,structural identification and appraisal analysis and assaying in phenobarbital.The purpose of the experiment was to improve the comprehensive strength,the ability of investigation and operation.The paper mainly discusses the design and application of the comprehensive experiment in the phenobarbital for pharmacy and Chinese medicine majors from the following aspects including design idea,teaching plan,effectiveness and popularization.
ABSTRACT
Objective To discuss the anesthetic effect of iv injection with propofol for pediatric orchiopexy.Methods Totally 80 children who needed orchiopexy were selected,and were divided into two groups randomly.The control group (39 cases) were iv given propofol and ketamine for anesthesia.The observation group (41 cases) were iv given propofol,ketamine,and remifentanil.The anesthetic effect of propofol for pediatric orchiopexy was evaluated by HR,MAP,SpO2,recovery time,dosage of propofol and ketamine,and postoperative adverse reaction.Results Before the injection and injection for 5 min,there was no statistical significance on MAP,HR,and SpO2 between two groups.Pulling the testicles,the MAP and HR in observation group were lower than those in control group (P ＜ 0.05).There was no statistical significance on SpO2.The recovery time of observation group was shorter than that of control group (P ＜ 0.05).And the dosages of propofol and ketamine in observation group were also less than those in control group (P ＜ 0.05).There was no statistical significance on postoperative adverse reaction between two groups.Conclusion The iv anesthesia with propofol has a good anesthetic effect on the pediatric orchiopexy.The anesthesia is stable and has little effect on vital signs,rapid postoperative recovery without increasing adverse reaction,which is worthy of clinical use.
