China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(04):-
Objective:To optimize the preparation of borneol-?-cyclodextrin inclusion complexes in Zhuyu Hewei Zhitong Capsules,and to establish the metered method of borneol in inclusion complexes.Methods:Orthogonal design was used and inclusion complex yield and inclusion rate of berneol were used as evaluation index to optimize the best preparation craft. The chromatographic conditions were:PEG-20M with 10%,3m??3mm of application concentration was used as stationary liquid phase,FID detector was used at 140℃,betula oil was used as internal standard substance and the sample was dissolved in Colonial spirit by ultrasounding.Results:The best preparation craft were:the weigh ratio of borneol and?-CD was 1:6,the ratio of?-CD and moisture addition was 1:10,reaction time was 30min,the temperature was 30℃.A good linearity was obtained when the concentration of borneol was between 0.7146-4.2878mg/ml(r=0.9999),the average recovery was 101.97%,RSD% was 1.77%.Conclusion:Three batches of tests indicated that the preparation of borneol inclusion complexes was stable and feasible. This assay method of borneol was accurate,sensitive and reproducible.

Objective:To analyze the effects of rational intervention on prophylactic antibiotics use in typeⅠIncision. Methods:A retrospective investigation method was used. Totally 170 cases with typeⅠIncision undergone in the hospital from April to Decem-ber 2013 were selected as the non-intervention group, and 173 cases with typeⅠIncision undergone in the hospital from April to De-cember 2014 were selected as the intervention group. The prophylactic antibiotics use, medication time, drug selection and duration of drug treatment were analyzed. Results:After intervention, the use rate of antibiotics was decreased from 67. 65% to 26. 59%, the ir-rational rate of use time was decreased from 15. 88% to 4. 63%, the irrational rate of treatment course was decreased from 30. 58% to 8. 09%, and the combination rate was declined from 10. 59% to 5. 20%. Conclusion:The rational prophylactic use of antimicrobial in type Ⅰ incision is improved through the intervention, and further efforts are still needed to improve the reasonable use.

Objective To investigate the influence of abnormal lipid metabolism on prognosis and quality of life in patients with severe COPD. Methods 134 patients with severe COPD in our hospital from September 2013 to January 2015 were selected as research objects, and their blood lipid levels were detected. The patients were divided into the normal group (n=61) and the low level group (n=73) according to the test results of lipid levels. 1-year mortality rate was statistically analyzed in both groups , and the WHOQOL-BREF health survey profile was applied to assess quality of life before and after treatment. Results 1-year survival rate in the normal group was 90.16%(55/61), which was higher than 73.97%(54/73) in the low level group (χ2=5.741, P=0.017). As compared with the normal group, the scores on physiological function, environment, social relationship, mental state, spirit / religious / belief, and total quality of lifewere markedly lower in the low level group after treatment (P < 0.05). The correlation analysis showed that plasma levels of TC, TG, and HDL-C were negatively correlated with 1-year mortality rate in patients with severe COPD (P < 0.05) but positively related with all dimensions in quality of life; plasma HDL-C level was positively related with 1-year mortality rate (P < 0.05), but negatively related with all dimensions in quality of life in patients with severe COPD (P < 0.05). Conclusions For patients with severe COPD, abnormal lipid metabolism is closely related with prognosis and quality of life. We should pay attention to nutritional support and control of abnormal lipid metabolism in those patients , leading to improvement of prognosis and quality of life.

AIM: To determine the median effective dose(ED50) of spinal anesthesia 0.75% ropivacaine for cesarean section. METHODS: Thirty-two ASAⅠ-Ⅱ parturients undergoing elective cesarean section delivery with use of combined spinal-epidural anesthesia were enrolled in this study. The initial dose of was 12.8 mg of 0.75% ropivacaine, and the dosing intervals were 98.4% of the preceding dosage. Doses for subsequent parturients were determined by the response of the previous parturient. Successful anesthesia was defined as a loss of sensation to an acupuncture stimulus at the T7 level, full motor blockade within 10 minutes after administration of the local anesthetic, analgesia of incision and the satisfaction of skelaxin evaluated by one operator. ED50 and its 95% confidence interval (CI) was determined with use of Dixon method. RESULTS: Five parturients were rejected out the study because of doubtful anesthsia. According to the rest twenty-seven parturients' data, the ED50 of intrathecal 0.75% ropivacaine was 11.97 mg (95% confidence interval [CI], 11.75-12.19 mg). CONCLUSION: The ED50 of spinal 0.75% ropivacaine for cesarean delivery under the conditions of this study were 11.97 mg.

Objective To evaluate sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia.Methods Seventy ASA Ⅰ children were randomly divided into two groups,35 children in every group.Children in group S were appliedsevoflurane inhalation[the minimum alveolar concentration(MAC)of sevoflurane was 1.0-1.5],children in group PK were applied ketamine inhalation and total venous anesthesia of propofol[80μg/(kg·min)]with ketamine[20μg/(kg·min)].Compared the time of anesthesia induction,tracheal catheter extubation,anesthesia recovery between the two groups.The mean arterial pressure(MAP),heart rate,pulse oxygen saturation(SpO_2)during anesthesia were compared.During 2 days after operation,the adverse effects such as nausea and vomit,lower grade of sleep quality were also compared.Results Compared with group PK,the time of anesthesia induction,tracheal catheter extubation and anesthesia recovery in group S were shorter (P<0.05),the incidence of emergence agitation in group S was higher(20.0%,7/35 vs 2.9%,1/35)(P<0.05).But nausea(17.1%,6/35),vomit(31.4%,11/35)and lower grade of sleep quality(54.3%,19/35)were higher in group PK than those in groups(all 2.9%,1/35)at 1 day after operation(P<0.05).The incidence of lower grade of sleep quality at2 days after operation in group PK(14.3%,5/35)was higher than that in group S(0)(P<0.05).Cardiovascular effects of children,such as MAP and heart rate during the period of tracheal catheter extubation in group S was higher than that in group PK.Conclusion Sevoflurane inhalation and propofol combined with ketamine total venous anesthesia in pediatric laparoscopic surgery of oblique inguinal hernia still has some disadvantages,the anesthesia technology is selected by anesthesia method and medicine combination.

Objective To investigate the effect of metformin ( MET) on learning and memory behavior in HFD-induced insulin-resistant rats.Methods Thirty male Sprague-Dawley (SD) rats were divided into three groups to receive either a normal diet (Control group) or a high-fat diet (two HFD groups) for four weeks(HFD+MET).From two HFD groups, one received vehicle ( HFD group ) alone and other MET administration ( HFD+MET group ) .MET was dissolved in drinking water at a concentration of 2 mg/ml.All rats were subjected to the glucose tolerance test ( GTT) and behavioral tests using the elevated plus maze ( EPM ) , open field test ( OFT ) , Morris water maze ( MWM ) test and the step-through passive avoidance test ( PA) after four-week consecutive MET treatment .Blood samples were collected for determination of glucose. Results MET attenuated the glucose resistant condition and improved cognitive behavior in MWM and PA, vs the HFD group. Conclusion MET can improve the impaired learning and memory behavior in HFD-induced insulin-resistant rats.
