Objective To investigate whether fluoxetine has therapeutic effect of clinical score and brain derived neurotrophic factor (BDNF) expression in serum of experimental autoimmune encephalomyelitis (EAE)model. Methods Rats were randomly divided into solvent control group (n=6) ,model control group ( n= 10)and fluoxetine group ( n= 10). The EAE model was prepared by injecting guinea pig spinal cord homogenate subcutaneously. The clinical score was daily measured according to the sign and symptoms of rats in the behavior examination. The serum BDNF level was measured by EL1SA. Results 1. Except for the solvent control group,the first sign of EAE(Piloerection) was detected on 4th day after immunization of rats from both model control group and fluoxetine group,then EAE rats had distal tail weakness on 8th day, and gradually developed into completely tail paralysis and limb paralysis. EAE rats' clinical score reached the peak on 16th day after immunization. 2. The clinical score of fluoxetine group became scientifically lower than model group since 18th day after immunization ( Fluoxetine group :3.27 ± 0. 33; Model control group :4.66 ± 0. 55, P < 0. 05 ). 3. Compared with the model control group,fluoxetine did not significantly increase the expression of serum BDNF in EAE model ( Fluoxetine group:62.27 ± 0.43; Model control group :61.67 ± 0.85, P > 0.05 ). Conclusion Fluoxetine reduced the clinical score of EAE since 18th day after immunization,which indicates fluoxetine could promote the recovery of neurological function in EAE rats. BDNF may not contribute to protective effect of fluoxetine in EAE animal.

OBJECTIVETo observe the effect of Wenyang Huoxue Lishui Recipe (WHLR) containing serum on the expression of cathepsin L (CatL) in puromycin aminonucleoside-induced injury of mouse glomerular podocytes.
METHODSMouse podocyte cells (MPCs) in vitro cultured were divided into the normal control group, the model group, the dexamethasone (DEX) group, 10% WHLR containing serum group, 20% WHLR containing serum group, the vehicle serum control group. MPCs in the normal control group were cultured at 37 degrees C culture solution for 24 h. 45 mg/L puromycin was acted on MPCs in the model group for 24 h. On the basis of puromycin intervention, 1 limol/L DEX was co-incubated in MPCs of the DEX group for 24 h; 10% or 20% WHLR containing serum was co-incubated in MPCs of the 10% WHLR containing serum group and 20% WHLR containing serum group for 24 h. The vehicle serum control group was also set up by incubating with WHLR containing serum alone for 24 h. The expression of CatL and its substrate Synaptopodin in podocytes were detected by cell immunofluorescence staining. FITC-conjugated phalloidin was used to stain F-actin. A cortical F-actin score index (CFS index) was designed to quantify the degree of cytoskeletal reorganization in cultured podocytes.
RESULTSCompared with the normal control group, the expression of synaptopodin significantly decreased and the expression of CatL significantly-increased in the model group. F-actin arranged in disorder, gradually forming pericellular F-actin ring. CFS index was obviously elevated (P < 0.01). Compared with the model group, the epression of synaptopodin increased, the expression of CatL decreased, and CFS index also decreased in the DEX group, 10% WHLR containing serum group, and 20% WHLR containing serum group (P < 0.05, P < 0.01). Compared with the DEX group, the expression of synaptopodin decreased in 10% WHLR containing serum group, CFS index also decreased in 20% WHLR containing serum group (P < 0.05).
CONCLUSIONSWHLR could up-regulate the expression of synaptopodin, down-regulate the expression of CatL, and alleviate cytoskeletal reorganization of F-actin. It was helpful to stabilize the cytoskeleton of F-actin and improve the merging of podocytes.

Objective To investigate the relationship between the root diameter of Angelica sinensis and its early bolting rate, and to decrease the bolting rate. Methods The seedling transplanting of A. sinensis with various root diameters was used to study the bolting rate and yield. Results Bolting plants can be observed in the field at June and the period from June to July is the bolting heyday. The bolting rate was the highest, up to 94.65%, in the treatment of root diameter ≥ 0.86 cm. However, it was only 1.63% in the treatment of root diameter ≤ 0.35 cm on Oct. 2nd. In the treatment of root diameter ≤ 0.35 cm, the seedling rate was only 33.62%, while in the treatment of root diameter ≥ 0.86 cm, the seedling rate was the highest, up to 95.75%, but the harvest seedling number was only 6 395 plant/hm2. In the treatment of root diameter of 0.46—0.55 cm, the harvest seedling number was 68 398 plant/hm2, which was significantly higher than other treatments. The highest yield appeared in the treatment of root diameter in 0.46—0.55 cm of transplanting seedling, the fresh and dry yields of A. sinensis were 5 717.58 kg/hm2 and 1 554.98 kg/hm2, respectively. Conclusion The seedlings with root diameter in the range of 0.46—0.65 cm should be selected to transplant in practice.
