OBJECTIVE: To investigate the effectiveness of preemptive analgesia with loxoprofen sodium orally, which was a kind of non-steroid anti-inflammatory drugs, in extractions of mandibular impacted third teeth. METHODS: There were questionnaires about postoperative pain for patients whose mandibular impacted third teeth were extracted from July 2017 to August 2017 in First Clinical Division of Peking University School and Hospital of Stomatology. All the patients did their routine clinical examinations and imaging examinations. After their mandibular impacted third teeth were extracted, the questionnaires were sent to them. The questionnaires were filled in by the patients on their own and returned one week later. There were 120 questionnaires that were sent and 105 questionnaires returned, of which 98 questionnaires were filled in completely. According to the inclusive criteria and exclusion criteria, 66 questionnaires were totally selected in this study. According to the time when the patients took their loxoprofen sodium orally firstly, the patients were divided into 3 groups. The first group was for patients who didn't take loxoprofen sodium during their extractions (non-medicine group). The second group was for patients who took 60 mg loxoprofen sodium 30 min before their extractions (preoperative group). The third group was for patients who took 60 mg loxoprofen sodium 30 min after their extractions (postoperative group). The operation time among the 3 groups was analyzed by Kruskal-Wallis method. The postoperative time points were 2, 4, 12,24 and 48 h after operation. The scores of visual analogue scales (VAS) for postoperative pain in each group at different postoperative time points were analyzed by Friedman method. At each postoperative time point, VAS scores in the different groups were analyzed by Kruskal-Wallis me-thod. The numbers of the patients taking loxoprofen sodium home and drug adverse reactions were also analyzed. RESULTS: The operation time of the 3 groups was 15.0 (5.0,30.0) min and had no significant differences (P=0.848).VAS scores of non-medicine group 2,4, 12,24 and 48 h after operation were 1.75 (0.1,10.0), 6.25 (1.5,10.0), 2.00 (0.1,8.0), 2.00 (0.1,6.0) and 0.5 (0.1,5.5) separately and had significant differences (P<0.001).The VAS score at 4 h after operation was higher than the VAS scores at other time points after operation (P<0.005). Four hours after the operations, the VAS scores of preoperative group [2.0 (0.1,10.0)] and postoperative group [2.0 (0.1,5.0)] were lower significantly than those of non-medicine group [6.25 (1.5,10.0)] (P<0.001).The numbers of the patients taking loxoprofen sodium home were 9(40.9%) in non-medicine group,5(21.8%) in preoperative group and 7(33.3%) in postoperative group. The number of the patients who had drug adverse reactions in preoperative group (n=3,13.0%) and in postoperative group (n=4,19.0%) was less than the number of the patients who had drug adverse reactions in non-medicine group (n=8,36.4%). CONCLUSION There were two protocols of preemptive analgesia with loxoprofen sodium orally in extractions of mandibular impacted third teeth, which were taking 60 mg loxoprofen sodium orally 30 min before the extractions and taking 60 mg loxoprofen sodium orally 30 min after the extractions. Both of the two preemptive analgesia protocols could decrease the postoperative pain significantly.

To compare the pharmacokinetics of syringin, eleutheroside E and isofraxidin after intravenous administration of each monomer and Ciwujia injection. Twenty-four Sprague-Dawley rats were randomly divided into four groups and intravenously administrated with syringin, eleutheroside E, isofraxidin, and Ciwujia injection, respectively. The concentrations of the three components in rat plasma were determined by LC-MS/MS. DAS 2.0 software was applied to calculate the pharmacokinetic parameters while the SPSS 17.0 software was used for statistical analysis. Significant difference (P < 0.05) was found between each monomer and the injection on the main pharmacokinetic parameters such as AUC, CL and t1,/2. Compared with the injection, the group treated with the syringin has obvious decrease in AUC, and increase in CL while the group treated with eleutheroside E has obvious increase in AUC, and decrease in CL The t1/2 of isofraxidin was prolonged in Ciwujia injection. Pharmacokinetic characters of the ingredients in the injection varied greatly from the monomer. Other constituents in the injection may have an impact on the pharmacokinetic profiles of these three components.

OBJECTIVETo compare the efficacy difference in the treatment of senile insomnia among western, medication, acupuncture and the integrated therapy of acupuncture and western medication.

METHODSNinety-eight patients of senile insomnia were randomized into a western medication group (30 cases), an acupuncture group (35 cases) and an integrated acupuncture and medication group (35 cases). In the western medication group, estazolam 1mg was prescribed, taken 30 min before going to bed, oryzanol 20 mg, oral administration, three times a day, for 4 weeks totally. In the acupuncture group, the simple acupuncture therapy was applied at Shenmen (HT 7), Sanyinjiao (SP 6), Anmian (Extra), Baihui (GV 20) and Sishencong (EX-HN 1), as well as the supplementary points selected according to the differentiation. The acupuncture treatment was given once a day, 5 treatments a week, for 4 weeks totally. In the integrated acupuncture and medication group, the western medication was combined with acupuncture. The dosage and usage of western medication were same as those in the western medication group; and acupoints in acupuncture treatment were same as those in the acupuncture group. The treatment lasted for 4 weeks in the three groups. Pittsburgh sleep quality index (PSQI) and clinical efficacy were observed before treatment, after 4 weeks' treatment and in 4 weeks after discontinuity of treatment in the three groups.

RESULTSFour weeks after treatment, the clinical curative rates were 3. 3% (1/30), 21. 2% (7/33) and 25. 7% (9/35) in the western medication group, the acupuncture group and the integrated acupuncture and medicines group separately. The total effective rates were 70. 0%(21/30), 93. 9%(31/33) and 97. 1%(34/35) in the three groups separately. The curative rates and the total effective rates in the integrated acupuncture and medication group and the acupuncture group were higher than those in the western medication group separately (all, P<0. 01). PSQI scores after 4 Weeks' treatment were all improved as compared with those before treatment in the three groups (all P<0. 05). PSQI score in either the integrated acupuncture and medication group or the acupuncture group was lower than that in the western medication group, indicating the significant difference (both P< 0. 05). Four weeks after discontinuity of treatment, the efficacy was stable in the acupuncture group and the integrated acupuncture and medication group. PSQI score did not change as compared with that in the 4th week of treatment. The score in the western medication group ran back, close to that before treatment (P>0. 05). During the treatment, a few patients had dry mouth in the western medication group. The adverse reactions were not discovered in the other two groups.

CONCLUSIONThe integrated therapy of acupuncture and medication achieves the quick efficacy on senile insomnia and rapidly relieves the symptoms, with quite high clinical curative rate and total effective rate obtained. The long-term efficacy is better than that of western medication. The integrated therapy is the first option among the three therapeutic programs.
