Journal of Zhejiang Chinese Medical University 2017;41(4):271-273,277
[Objective] To explore the mechanism of acupuncture at Zusanli point(ST36) in the treatment of functional gastrointestinal disorders(FGIDs). [Methods] A total of 40 Wistar rats were randomized into normal(n=10),model(n=10), Zusanli point(ST36),non-acupuncture point(n=10). FGIDs model was established by exerting the factors of cold-constraint stimulation and hunger disorder synthesis . And the content of rats serum and stomach tissue Gastrin (GAS) and Motilin(MTL) was observed by radioimmuno-assay. [ Results] Compared with the normal group, the content of rats serum and stomach tissue GAS and MTL of the model group was significantly reduced(P<0.01);Compared with the model group, the content of rats serum and stomach tissue GAS and MTL of ST36 group was significantly ascended(P<0.01);Compared with the non-acupuncture point group, the content of rats serum and stomach tissue GAS and MTL of ST36 group had statistically significant differences(P<0.01). [Conclusion] Acupuncture at ST36 had obvious improvement in FGIDs, its mechanism was closely related to GAS and MTL.

Chinese Journal of Anesthesiology 2013;(1):40-42
Objective To evaluate the effects of different types of extracorporeal circuits (ECCs) on the concentrations of sufentanil in the priming solution.Methods The experiment was performed in three groups (n =6 each).Two types of ECCs were used:Xi-jing type 90 oxygenator (group Ⅰ) and Termo Capiox SX18 membrane oxygenator (group Ⅱ),while in control group (group Ⅲ) a glass container was used.The ECC and glass container were filled with the priming solution (succinylated gelatin 1000 ml + lactated Ringer' s solution 1000 ml).Sufentanil 15 μg (concentration 7.5 ng/ml) was then added to the priming solution.The priming solution was circulated in the closed ECC or stirred in the glass container.The concentration of sufentanil in the priming solution was determined by gas chromatography-mass spectrometry at 3,5,10,20,30,40,50,60,70,80 and 90 min after addition of sufentanil.Results The concentration of sufentanil in the priming solution was significantly decreased at the different time points in groups Ⅰ and Ⅱ as compared with group Ⅲ (P < 0.05).The concentration of sufentanil in the priming solution was significantly lower at each time point in group Ⅰ than in group Ⅱ (P <0.05).Conclusion Both the two types of ECCs can absorb sufentanil and the adsorption of Xi-jing type 90 oxygenator is stronger than that of Termo Capiox SX18 membrane oxygenator.

Objective To modify gas chromatography-mass spectrometry (GC-MS) for determination of plasma sufentanil concentrations.Methods Fentanyl was used as the internal standard.The plasma samples were extracted with ethyl acetate and petroleum ether.An HP-5MS capillary column was used.The initial temperature of the column was set at 130 ℃,and the final temperature was 320 ℃.The injector port temperature was set at 290 ℃,and the interface temperature was 300 ℃.The carrier gas was high purity helium (purity 99.999%) with a constant flow rate of 1 ml/min.The injection volume was 1 μl with splitless injection.The MS conditions were as follows:EI source,ion source temperature 230 ℃,four-pole temperature 150 ℃,electron bombardment energy 70 eV,multiply voltage 2112 V,selective ion monitoring mode,solvent delay 7 min.The characteristic ions of sufentanil and fentanyl were obtained in 8.20-8.40 min and 7.60-7.80 min,respectively,according to the characteristic ion curve of sufentanil and fentanyl.Results The standard curve of sufentanil had good linear relationship in the range of 0.02-10.00 ng/ml and the equation was Y =0.1625X + 0.0316,R2 =0.9987.The extraction recovery was more than 80%,intra-day and inter-day determinations were less than 8%,and the limit of detection was 0.02 ng/ml.Conclusion When modified GC-MS is applied to determine the concentrations of sufentanil in plasma,not only the determination is sensitive and accurate,but also the procedures are simplified,and it is more suitable for the pharmacological research of sufentanil.
5.Hydroxyapatite orbital implant drilling procedure:a follow-up study of 68 cases
Chinese Journal of Medical Aesthetics and Cosmetology 2001;0(04):-
Objective To evaluate the middle and long term effects of the two-stage procedures of drilling for hydroxyapatite orbital implant and inserting a motility peg, and to investigate the pathogenesis and treatment of the various complications during the procedure. Methods This retospective study included 68 patients who had underwent the drilling of the hydroxyapatite and motility peg placement for over 3 years. Mean age at operation was 30.7 years (range from 17~60 years). All patients were placed plastic peg. Information recorded included pre-and post-operative facial appearance, motility of the artificial eye, conjunctival sac discharge and other complications. Results No secondary infection occured in 36~72 months of follow up. All patients felt that there had been an improvement in the motility of their artificial eye. And their cosmetic appearance was acceptable. The most frequent complication encountered was discharge from conjunctiva sac, which occurred in 31 patients. Extrusion of the motility peg was found in 6 patients. 5 patients had exuberant granulation in conjunctiva sac. Conclusion Drilling of the hydroxyapatite implant improves both the appearance and the motility of the artificial eye. Complications are minor and can be easily prevented and treated. The vascularization of HA sphere with good motility should be drilled at relatively larger conjunctival sac in the patients who can cooperate under local anesthesia.

Objective To investigate the role of glucagon peptide-1(GLP-1) in blood pressure variability (BPV) in diabetic hypertensive patients. Methods A total of 120 diabetic hypertensive patients were included in this study. GLP-1 was used for the treatment. The values of body mass index (BMI), fasting blood glucose, glycosylated hemoglobin, creatine and 24-hour ambulatory blood pressure (BP) monitoring were detected before and after treatment with GLP-1 for six months. The clinical indices were compared before and after treatment. Results The values of fasting blood glucose (mmol/L:7.12± 0.64 vs 9.19±2.78), glycosylated hemoglobin (%:7.00±0.14 vs 8.28±1.32) and BMI (kg/m2:19.30±3.24 vs 24.5±4.53 ) were de-creased to the normal level after GLP-1 treatment for six months (P<0.05). There were significant decrease in the 24-h sys-tolic BP (mmHg:135.02 ± 16.57 vs 139.52 ± 15.60), daytime systolic BP (mmHg:132.5 ± 14.6 vs 136.44 ± 14.24), 24-h systolic BP variability (mmHg:12.20 ± 1.44 vs 12.73 ± 1.66), daytime systolic BP variability (mmHg:11.11 ± 1.48 vs 11.74 ± 1.52 ), and daytime diastolic BP variability (mmHg:7.03±1.42 vs 7.43±1.45) after GLP-1 treatment for six months (P<0.05). Conclu-sion GLP-1 can decrease BPV in diabetic hypertensive patients.
