Objective To summarize the clinical characteristics of Foix-Chavany-Marie syndrome.Methods The clinical,electroencephalography and imaging characteristics,as well as etiology,treatment and prognosis of 4 cases of Foix-Chavany-Marie syndrome were retrospectively evaluated,and relevant literature was reviewed to investigate its pathogenesis.Results All the 4 cases presented with hypersalivation,facial diplegia,dysarthria and dysphagia with autonomic-voluntary dissociation.Brain MRI showed bilateral cortical or subcortical lesions in the opercula and perisylvian areas.Three cases were secondary to encephalitis,and 1 case was related to perinatal hypoxic-ischemic encephalopathy.After administration of antiepileptic drugs,they were free of seizures.But all the other symptoms remained.Conclusions Autonomic-voluntary dissociation is a feature of Foix-Chavany-Marie syndrome.Most patients are due to bilateral structural or functional lesions between motor cortices and brain-stem cranial motor nuclei.The prognosis depends on the heterogeneous etiologies,such as encephalitis and cerebrovascular disease.

The spread out agent was chloroform-methanol-ammonia solution(4mol/L)(2∶6∶1). Dual wavelength scanning:strychnine and brucine:?s=254nm,?r=325nm;ephedrine:?s=500nm,?r=440nm.RESULTS:The within-day recoveries of strychnine,brucine and ephedrine were 99.048?2.388,99.532?0.958 and 99.504?0.555;the between-day recoveries were 98.796?1.058,99.58?0.476 and 99.42?0.838;the contents were(1.474?0.047)%,(1.372?0.052)%and(1.506?0.064)%(n=4) respectively.CONCLUSION:This method is stable and reliable and can be used for determination of the contents of this preparation.

【Objective】To observe the influence of temperature and perfusate modifier on in-vitro mass transfer coefficient of microdialysis with sinomenine as a model drug.【Methods】The in-vitro relative recovery(RR) was assayed by HPLC at different temperatures and in perfusate including different concentrations of alcohol,and then the mass transfer coefficient was calculated.【Results】In-vitro RR increased with the temperature and the concentrations of alcohol,so did the mass transfer coefficient.【Conclusion】Temperature and alcohol at different concentrations have an effect on RR and mass transfer coefficient of microdialysis with sinomenine as a model drug.

AIM: The transdermal absorption data of sinomenine patch was fitted by grey model GM(1,1) and compared with other models. METHODS: The transdermal absorption experiment was carried out with Franz diffusion cell and the GM(1,1) was established by accumulation generation operator (AGO). RESULTS: The fitting precision was compared by using mean relative error and grey absolute correlation degree as evaluation criterion. CONCLUSION: The fitting precision of GM(1,1) is as high as acceptable.

AIM: To elevate the stability of the volatile oil in Jiufen Cataplasm (Semen strychni,Herba ephedrae,Oilbanum and Myrrha) with the help of inclusion with ?-Cyclodextrin. METHODS: The quality of the volatile oil in Jiufen Cataplasm before and after stability test was examined by thin layer chromatography and differential thermal analysis and thermogravimetric analysis. RESULTS: The combination of volatile oil and ?-cyclodextrin could form stable inclusion compound that helped constant in before and after inclusion. CONCLUSION: The process of enclosure with ?-CD can keep the active components of the volatile oil in Jiufen Cataplasm.

AIM To study the preparation and stability of sinomenine liposomes. METHODS Taking entrapment efficiency as index, different preparation methods, including thin film dispersion, reverse-phase evaporation, and aether injection were optimized. The leakage rate, the uptake rate and the storage temperature of the liposomes were studied at the same time. RESULTS The entrapment efficiency of reverse-phase evaporation was the lowest as 48.93 % . The entrapment efficiency of thin film dispersion and aether injection were near, as 68.91 T《B》 % and 66.57 % , respectively. CONCLUSION Thin film dispersion has higher entrapment efficiency and low command to the equipment. So it is suitable for the production of sinomenine liposomes on a large scale.

AIM: To study the stability on controlled release pellets of Ginkgolides. METHODS: According to the requirement of stability test of appendix XIXC of China Pharmacopoeia (2000 edition, Part Ⅱ), test for influencing factor, accelerated test and samples kept at room temperature were studied, applying similar factor analysis to appreciate the release stability. RESULTS: All the indexes accorded with the standard. CONCLUSION: Controlled release pellets have a good stability.

Objective: To study the effect of vitamin A deficiency on lipid peroxidation and antioxidation system in rats. [WT5FZ]Methods: According to body weight, 33 Wistar male rats were randomly divided into 3 groups, A (Vitamin A complete deficiency group), B (Vitamin A low grade deficiency group), C (Vitamin A normal control group). The study lasted 84 days. The serum vitamin A, serum, liver and brain SOD activities, blood, liver and brain GSH Px activities, serum, liver and brain MDA were studied. Spin trapping techniques combined with ESR were used to capture and detect free radicals generated in liver. [WT5FZ]Results: In vitamin A completely deficient group and vitamin A low grade deficient group, SOD activities of serum, liver and brain, and the GSH Px activities of blood, liver and brain decreased significantly, while LPO contents of serum, liver and serum increased markedly, and typical free radicals peaks in liver were indicated by ESR spectra. [WT5FZ]Conclusion: Vitamin A deficiency results in decrease of antioxidation capacity and increase of lipid peroxidation.

Objective: To study the releasing rule of Artesunate TDD s (ASTDDs). Methods: To prepare the ASTDDS and determine the content of artesunate, the transdermal experiments are used to study the relation between accumulative releasing ratio or releasing speed and releasing time. Results: The content of artesunate is about 45mg/10cm 2 and the accumulative releasing ratio increases with releasing time, but releasing speed is constant when the releasing speed reached some value. Conclusion: The releasing rule of ASTDDs conforms to Higuchi equation. The ASTDDs can come to durable effect.
