BACKGROUND: Electroacupuncture has a good clinical effect on Alzheimer disease, but its mechanism remains unclear.OBJECTIVE: To observe the effect of electroacupuncture on number of synaptic numeric density (Nv), surface density (Sv) and average size of synaptic conjunction and ultrastructure in hippocampal CA3 area of neurons of model rats with Alzheimer disease (AD).DESIGN: Completely randomized grouping and controlled study.SETTING: Department of Traditional Chinese Medicine of Sichuan Provincial People's Hospital; College of Acupuncture & Moxibustion and Massage of Chengdu University of Traditional Chinese Medicine.MATERIALS: A total of 50 male SD rats of 24-month old weighing (480±20) g and 6 male rats of 3-month old weighing (250±15) g were selected in this study. Passage water maze (2.1×1.7×0.6) m3 was made of black glasses with 40 cm deep water and 4 caecums. WQ1002F Hans electrically heated distilling apparatus was used.METHODS: The experiment was carried out at the Grade Ⅲ Animal Experimental Center of Chengdu University of Traditional Chinese Medicine between, September 2002 and June 2003. ① Old SD rats were grouped on the basis of water-maze test results. Firstly, 6 young rats were submitted to water-maze test at 8 days before modeling for 4 continuous days to obtain average escaping latency. Secondly, 50 old rats were accepted in the water-maze test at 4 continuous days before modeling to obtain average escaping latency. A total of 36 rats whose latencies were less than average values plus one standard deviation of young rats were regarded as normal old rats. Among them, 12 rats were randomly divided into control group and sham operation group with 6 in each. Another 24 rats were transected at fornix-fimbria AD modeling. Thirdly, 24 modeling rats were all adopted in the water-maze test at 2 days after modeling. Rats whose latencies were more than average value plus two standard deviation of young rats were chosen as AD model. Twelve AD models were randomly divided into model group and electroacupuncture group with 6 in each.② On the 6th day after modeling, rats in electroacupuncture group were acupunctured at Baihui (Du20) of 0.5 inch in slope, Yongquan (K1),Taixi (K3) and Xuehai(Sp10) of 0.3 inch in depth with No. 30 milli-needle (3.33 cm); Then, electrically heated distilling apparatus was used with successive waves, 20 Hz in frequency and 2-4 V in voltage. Tolerant stress of rats at quiet state was regarded as the standard value (2 mA),the needle was maintained for 30 minutes, and the acupuncture was done once a day for totally 20 successive days. Rats in control group sham operation group (cerebral cortex was exposured at the same site as model rats, and fornix-fimbria was not cut off) and model group were only fixed but treated with nothing. ③ After treatment, ultrastructure in hippocampal CA3 area of rats was observed with transmission electron microscope;synapse numbers and cross-point numbers between synaptic conjunction and test line were counted with stereological technique; stereological parameters, such as numeric density (Nv), area surface (Sv) and average size of synaptic conjunction, which could reflect plastic changes of synaptic form, were calculated at the same time. ④ Differences between every two groups were compared with t test at regular variance and t'test at irregular variance.MAIN OUTCOME MEASURES: Comparisons of numeric density (Nv),surface density (Sv) and average size of synaptic conjunction.RESULTS: A total of 24 old rats were involved in the final analysis with 6 in each group. ① Ultrastructure: Synaptic density of control and sham operation group was higher than that of model group, and average area of synapse was smaller;, synaptic density of electroacupuncture group increased compared with that of model group, and average area of synapse was smaller. ② Numeric density and surface density in hippocampal CA3 area in model and electroacupuncture group were lower than those of control group and sham operation group (P ＜ 0.05). There was no significant difference between sham operation group and control group (P ＞ 0.05), and those of electroacupuncture group were higher than those of model group (P ＜ 0.01). ③ Average size of synaptic conjunction in hippocampal CA3 of model and electroacupuncture group was higher than that of control and sham operation group (P ＜ 0.05). There was no significant difference between sham operation group and control group (P ＞ 0.05), and the value of electroacupuncture group was lower than that of model group (P ＜ 0.01). CONCLUSION: Electrotherapy can repair synaptic form and inhibit synaptic degeneration of hippocampal neurons in AD rats.

Objective To prepare and characterize nanoparticles in-loaded one-way release-controlled chitosan membrane,and to explore the release-controlled rule of the film in vitro.Methods The chitosan nanoparticles were prepared by inverse crosslinking-emulsion method.The one-way release-controlled membrane was prepared by a casting method.Transmission electron microscope (TEM) was used to evaluate the morphological properties and particle size analyzer was used to analyze particle size distribution.The morphology of the membrane was inspected through scanning electron microscope (SEM).MTT assay was applied to determine the biological safety of chitosan nanoparticles.The distribution of the nanoparticles was observed by fluorescence microscope.The in vitro release studies were adopted to evaluate the release-controlled rule.Results The four kinds of nanoparticles had spherical shapes and uniform particle size.The size of the hyaluronic acid-coated chitosan nanoparticle was (255.40±39.10) nm.Hyaluronic acid-coated chitosan nanoparticles showed the best property of sustained release and biocompatibility.The membrane had a loose inner layer and a dense outer layer,and the distribution of the nanoparticles was uniform in the inner layer of the membrane.The release of protein from membrane was unidirectional and the membrane displayed good controlled release property.Conclusions The nanoparticles in-loaded one-way release-controlled chitosan membrane presents good one-way sustained release performance.It is potentially useful in delivery system of growth factors.

Objective To assess the effects of different doses of oxycodone hydrochloride on spontaneous breathing and consciousness level of patients,so as to provide theoretical basis for its clinical application.Sixty patients undergoing elective surgery were randomly divided into 3 groups:0.05 mg · kg-1 oxycodone group (group P1),0.1 mg· kg-1 oxycodone group (group P2),0.2 mg· kg-1 oxycodone group (group P3).Changes of respiratory rate (RR),end tidal carbon dioxide partial pressure (PETCO2),saturation of blood oxygen (SpO2) and bispectral index (BIS) were recorded in patients before injection (t0) and 1-15 min after injection (once per min);the Observer's Assessment of Alertness/Sedation Scale (OAA/S) were recorded.At the same time,the adverse reactions were observed after drug injection in each group.Results In 10 min after injection there were no significant differences in the RR,SpO2,PETCO2,BIS and OAA/S in group P1 as compared with those before injection (P＞0.05).The patients had no respiratory depression in group P1.In group P2,RR had a significant decrease (P＜0.05),BIS had decreased but were greater than 85;there were no significant differences in the SpO2,PETCO2 and OAA/S (P＞0.05).The P2 group had 3 cases with respiratory frequency＜10 per min,but SpO2 were all greater than 94％.In group P3,There were significant differences in the RR,SpO2,PETCO2,BIS and OAA/S (P＜0.05).The P3 group had 12 cases of respiratory frequency ＜10 per min,at the same time there were 8 patients with SpO2 less than 94％.With the increasing dose,the frequency of respiratory inhibition increased,and there were statistical differences (P＜ 0.05).In 15 min after injection,RR,SpO2,PETCO2,BIS and OAA/S were not significantly different in group P1 and P2 as compared with those before injection (P＞0.05).In group P3,RR was significantly different after injection (P＜0.05).There were no significant differences in the SpO2,PETCO2,BIS and OAA/S in group P3 after injection (P＞0.05).No patients complained with chest wall stiffness,nausea and vomiting,cough and other adverse reactions in group P 1 and P2.In group P3,three patients had nausea 5 min after injection,two patients complained of chest skin itching but no skin flushing.Conclusion With the increasing dose,effect of oxycodone hydrochloride on breathing and consciousness level of patients gradually increased.Injection of oxycodone hydrochloride 0.05 mg · kg-1 had no obvious effect on breathing and consciousness.After injection of oxycodone hydrochloride 0.1 and 0.2 mg · kg-1 for 5 to 10 min,respiration inhibition and sedative effect were the most obvious.Fifteen min after injection,the 0.1 mg · kg-1 dose group recovered to the level before,the respiratory rate of the 0.2 mg · kg-1 dose group was still lower than that before the injection.
