ObjectiveTo compare the effects of two methods for the treatment of delayed defecation of neonatal meconium. Methods Sixty-seven neonates with delayed defecation of neonatal meconium were divided into experiment group (n=37) and control group (n=30). The former group was managed with abdominal massage followed by glycerol enema and the latter with abdominal massage followed by anus stimulation.Then the groups were compared in terms of the time for initial defecation of meconium,the volume of defecation,exhanstion time for defecation,abdominal distention and vomiting and serum bilirubin within 7 days.Result The treatment group was superior to the control one in terms of time for initial defecation of meconium,the volume of defecation, exhanstion time for defecation (P<0.05) and the incidences of abdominal distention,vomiting and serum bilirubin within 7 days were significantly lower than the control group (P<0.05).Conclusions The method of glycerol enema combined with abdominal massage is more effective for promoting defecation of neonatal meconium than the method of anus stimulation.It can reduce the incidence of abdominal distension,vomiting and pathological jaundice.

Objective To study the effectiveness of subfascial endoscopic communicating branch vein ablation in treating communi cating branch vein insufficiency.Methods Fifty-seven cases of primary lower ext remity vein valve insufficiency complicated by communicating vein insufficiency diagnosed by venography and color duplex were treated with subfascial endoscopic communicating branch vein ablation, and their information was analyzed retrosp ectively.Results Swelling was observed in leg of 7 cases after operation, and disappeared within one week spontaneously. Incision infec tion occurred in 2 cases and skin ambustion happened in 2 cases. Superficial vei n varicosis disappeared in all case, skin pigmentatin declined significantly and ulcers healed in 2-3 weeks.Conclusion Subfascial endoscopic communicating branch vein ablation is an excellent choice in treating communicating branch ve in insufficiency.

Objective To investigate the effects of hyperbaric oxygen on learning and memory ability in rats with a model of VPA autism and on the pyramidal cells in the CA1 region of the hippocampus.Methods An animal model of autism was established in the offspring of Wistar rats which had received a single intraperitoneal injection of sodium valproate at the 12.5th day of pregnancy.A total of 48 male VPA autism model rats were randomly divided into the hyperbaric oxygen group,a high pressure air group,a normal pressure high oxygen group and a normal pressure air group (each group with 12 rats).A normal control group was obtained by injecting physiological saline.The autism model rats of the hyperbaric oxygen group were treated with high pressure oxygen in an animal experiment cabin which was cleaned with pure oxygen for 10 min,pressurized for 15 min,held at 2.0 atmospheres absolute (ATA) for 45 min and then had the pressure relieved over 15 min.For the high pressure air group the cabin was pressurized with air for 15 min,held at 2.0 ATA for 45 min and the pressure was relieved over 15 min.For the normal pressure,high oxygen group the cabin was cleaned for 10 min with pure oxygen,then pure oxygen was supplied for 1 hour with the cabin door open.The normal pressure air group rats were placed in the open cabin with no pressure or additional oxygen.The testing lasted 7 days for 1 hour per day.The normal control group rats were placed in ordinary cages.Learning and memory were evaluated using the Y electric maze test before and after the interventions.Any changes in the pyramidal cells in the CA1 region of the hippocampus were observed after hematoxylin and eosin (HE) staining.Results The average number of tries of the hyperbaric oxygen group after treatment was significantly less than before treatment and memory retention times were increased.The number was also less in the normobaric hyperoxia group and memory retention times again improved.The number of apoptotic cells was reduced and the number of normal form cells in the CA1 region increased after the hyperbaric oxygen intervention.Conclusions The learning and memory abilities of the autistic rats improved after the hyperbaric oxygen intervention.Pyramidal cells in the CA1 region proliferated and the number of apoptotic cell decreased.This may be the mechanism by which hyperbaric oxygen intervention treats autism.

AIM: To find optimium conditions which would be beneficial to the microencapsulation of the citrus oils microcapsules. METHODS: The influenceing factors,such as the kind and concentration of coating material、plasticizer and antiadherent,ratio of volatile oil to coating material were investigated using appearance,encapsulation efficiency and volatile oil loading as evaluation parameters. RESULTS: The microcapsules prepared by optimium conditions were smooth and possessed encapsulation efficiency of 84.50%,volatile oil loading of 28.32%. CONCLUSION: The optimum conditions are chosen reasonably to help increase the stability of volatile oils microcapsules.

AIM: To establish a method of evaluating totally the quality of mandarin oils microcapsules. METHODS: The quality evaluation method of the mandarin oils microcapsules was investigated according to the appearance shape,in-vitro release,compressibility index and microcapsule dissociative film's physical characters research. RESULTS: The method to investigate compressibility index,hydroscopicity and the capability of penetrating oxygen and resisting tension was established. CONCLUSION: These methods can evaluate the quality of essential oils microcapsules rather exactly.

Objective To investigate the influence factors on preparation of citrus volatile oil microcapsules by spray drying technique.Methods The citrus volatile oil microcapsules were prepared by spray drying technique with arabic gum as coating material.The temperature of aeration,injection speed,spray rate of flow,and exhausting volume were observed by single factor and the technical parameters were optimized by uniform design.Results The optimum condition including ratio of drug to coating material(0.9),plasticizer to coationg material(0.15),the temperature of aeration(145 ℃),injection speed(18 mL/min);and spray rate of flow(40 L/h).The microcapsules prepared by optimum conditions were smooth and possessed average encapsulation efficency in 84.50%,average drug loading in 28.32%.Conclusion The optimum conditions are chosen reasonably,which can increase the stability of citrus volatile oil microcapsules significantly.

Plants in Ainsliaea genus, belongs to Compositae family, are traditional Chinese medicine and widely used in folk. These plants contain various types of chemical components, and main components are sesquiterpene lactone and its glycosides. In addition, there are triterpenoids, flavonoids, steroids, phenolic acid, long chain fatty acid and volatile oils. Recently, much attention has been payed to varlous research of A. fragrans. This paper reviewed and summarized the chemical components to provide the theoretical basis for the use of Ainsliaea.
