Objective:To observe the influence of sevoflurane and propofol anesthesia on hemodynamics in laparoscopic cholecys-tectomy. Methods:Totally 98 patients with laparoscopic cholecystectomy were randomly divided into P group and S group. P group was with propofol for anesthesia, and S group was with sevoflurane for anesthesia. Before anesthesia, 2min after intubation, 10 min af-ter intubation, 5min and 30min after pneumoperitoneum, and after the surgery, the levels of blood glucose and cortisol, and hemody-namic changes in the two groups were observed, and the incidence of adverse reactions was also studied. Results:2 min and 10 min af-ter the anesthesia, the blood glucose levels in the two groups were significantly lower than those before the anesthesia(P<0.05 or 0. 01), while 30 min after pneumoperitoneum and after the operation, the blood glucose levels were increased(P<0. 01). The blood glucose levels in S group after the operation were much lower than those in P group (P<0. 01). 2 min after intubation, cortisol was decreased in the two groups (P<0. 05 or 0. 01). 5 min after pneumoperitoneum and after the operation, cortisol levels were higher than those before the anesthesia in P group(P<0. 01), and 5 min and 30 min after pneumoperitoneum and after the operation, cortisol levels in S group were lower than those in P group (P<0. 01). HR and SPO2 showed no significant changes in the two groups during the whole process (P>0. 05). 2 min and 10 min after intubation, SBP in the two groups was decreased (P<0. 01), and 5 min and 30 min after pneumoperitoneum, there was notable difference in SBP between the groups (P<0. 01). 2 min and 10 min after intuba-tion, DBP was decreased in the two groups (P<0. 01), and the difference was significant between the groups (P<0. 01). 5 min and 30 min after pneumoperitoneum, DBP in P group had notable difference with that in S group (P<0. 05). The incidence of adverse re-actions in the two groups showed no significant difference (P>0. 05). Conclusion: Sevoflurane anesthesia in laparoscopic cholecys-tectomy can keep stable hemodynamics in the patients, and the anesthetic effect is better than propofol.

Objective:To study the effect of priming technique combined with time limit on shortening the onset time of cisatra-curium besilate. Methods:Totally 112 adult patients undergoing selective operation with general anesthesia were randomly divided into group A, B and C. Fentanyl with the dose of 4 μg·kg-1 and propofol with the dose of 2 mg·kg-1 were used in the three groups as the inducing agents. Group A was first with intravenous injection of cisatracurium besilate 20 μg·kg-1 , and 3 minutes later, the in-ducing agents and cisatracurium besilate with the dose of 80 μg·kg-1 were respectively injected. Group B was first with intravenous injection of cisatracurium besilate with the dose of l00 μg·kg-1 , and 1. 5 minutes later, the inducing agents were injected. Group C was respectively injected with the inducing drugs and cisatracurium besilate with the dose of l00 μg·kg-1 . The T1 percentage before the induction, the time of 90% and 100% inhibition of muscle twitching, the rating of trachea cannula and adverse drug reactions in the three groups were observed and compared. Results:There was no significant difference in the excellent rate of trachea cannula a-mong the three groups (P>0. 05). Compared with group A and B, group C showed no T1 suppression before the induction, while group B with T1 of (9. 8 ± 2. 6) was higher than group A with T1 of (3. 2 ± 1. 5) (P<0. 01). The time of 90% and 100% inhibition of muscle twitching in group C was the longest (P<0. 01), and the incidence of adverse drug reactions in group C was also the highest (P<0. 05). Conclusion:The application of priming principle and time limit can effectively shorten the onset time of cisatracurium be-silate with significant effect and high safety.

Objective:To study the perioral soft tissue characteristics of the subjects with ClassⅡDivisionⅠand various vertical pat-terns. Methods:Lateral cephalograms of 90 adults ( half men, half women) were divided into 3 groups based on GoGn-SN angle:low angle, normal angle and high angle(n=30). The perioral soft tissues were measured and compared for the determination of the vertical skeletal variables influencing soft tissue characteristics. Results: The subjects with low angle showed significantly smaller values than those with high angle for basic lower lip thickness and lower lip length(P<0. 05). Most measurements of soft tissue thickness were greater in men than in women in all groups, especially for basic upper lip thickness and upper lower lip thickness(P<0. 05). Conclu-sion:Orthodontists need to pay more attention to the differences of perioral soft tissue in the subjects with various vertical patters to ob-tain balance of the facial harmony in orthodontic treatment.

Polysaccharides with multiple biological activities are usually considered as one of the major bioactive compounds in Chinese medicines (CMs). At present, the development of drug and functional foods related to polysaccharides have attracted a great deal of attention due to their great potential effects and diverse action mechanisms. However, quality control of polysaccharides is the bottleneck and a challenge due to their complexity and chemical diversity. Actually, the bioactivities of polysaccharides are closely related to their molecular structures. In order to ensure their safety and efficacy, the development of novel approaches based on the molecular structures for the improvement of quality control of polysaccharides is significantly important. Therefore, in this article, the relationship between biological activities and chemical structures, as well as the action mechanisms of polysaccharides from CMs were summarized first. Furthermore, saccharide mapping, a novel strategy for quality control of bioactive polysaccharides from CMs, was introduced and the application and perspectives were also discussed.
