Objective To explore the effects of magnesium valprote on behaviors and lipid peroxidation of brain in chronic stress depression mice.Methods 40 male mice were randomly divided into normal control group,model group, amitriptyline control group and magnesium valprote group, and.10 mice each group.Except normal control group,other groups were separated one mouse in each box and exposed to 21 days chronic unpredictable stressors, and the mice of normal control group were fed in a box and stress-free.During the stress, the mice of amitriptyline control group were applied amitriptyline(0.2 mg/10g) by intragastric every day,magnesium valprote group were given intragastrically magnesium valprote (0.8 mg/10g), and the mice of model and normal control group were administrated with normal sodium of the same volume by the same method.On 7th, 14th,21st day, all mice weight were weighed and weight gain was calculated.The ethology examination was performed by using jigglecage connected with Biology Function Experiment System and experiment of sucrose solution consumption after the chronic stress.At the end of experiment, all mice were killed, and then their brains were removed and made into brain homogenate.The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and the content of malondialdehyde(MDA) in brain homogenate were analyzed by spectrophotometry.Results Compared with model group, magnesium valprote group were increased on locomotor activity number(97.50 ± 20.54,302.30± 39.04, t = 31.1432, P ＜ 0.01 ), sucrose solution consumption ( ( 15.30 ± 3.60 ) ml, ( 23.70 ± 4.45 ) ml, t =9.8446, P＜0.01) ,body weight gain(( 10.56 ± 1.53)g,( 12.63 ±2.12)g, t=5.3113, P=0.007) ,the activity of SOD( t =3.8428, P=0.004) ,and GSH-Px( t= 3.4143, P=0.007), but decreased on irritation number( t =17.1370, P ＜ 0.01 ) and the content of MDA( t= 11.0778, P = 0.002).Conclusion Magnesium valprote can ameliorate behavior impairment of chronic stress-induced depression mice, and the observed antidepressant-like effects may be related to inhibition lipid peroxidation of mice brain.

The effects of melittin on the activities of Na+-K+-ATPase and glucose-6-phosphate dehydrogenase (G-6-PD) which are on the membrane of red blood cell (RBC) are chosen as the index of this study. The possible target sites of these effects through enzyme activity determination by spectrophotometry are investigated, and the hemolytic process and the activity change of these two types of enzymes on the RBC membrane are discussed. The results show that the main mode of melittin inhibition to the activity of enzymes on the RBC membrane is the coexistence of adhesion/insertion form and free-state form, and the effect of the former is more stronger than the latter. The K+ binding site of Na+-K+-ATPase is one of the target sites of melittin. The membrane-insertion process of melittin synchronizes with the action of melittin on this enzyme. Melittin slowly inhibits the catalysis of G-6-PD through the action on G-6-P and NADP, and the extent in which melittin forms tetramers isclosely related to the enzyme activity. EDTA inhibits the aggregation of melittin, and interferes with its action on G-6-P. The biochemical mechanisms of melittin effects on the substrate G-6-P and the coenzyme NADP are similar, and the inhibition of melittin is not related to the structure of G-6-PD.

Objective To investigate the changes in the prescriptions of antidepressants for inpatients with psychosis from 2005 to 2008. Methods The prescriptions of antidepressants for all the inpatients with psychosis in Shanghai Mental Health Center were investigated by one day survey on each June 1st from 2005 to 2008. The most common diseases treated with antidepressants, the most commonly used antidepressants, the average dosage of antidepressants and the combination use of antidepressants were analysed. Results The most common diseases treated with antidepressants were affective disorder, schizophrenia and neurosis. The prescription rate of tricyclic antidepressants declined year by year, and that of selective serotonin reuptake inhibitors (SSRIs) fluctuated moderately, while that of antidepressants of newer generation with the other transmitter mechanisms such as venlafaxine, mitrazapine and trazodone increased gradually. Single antidepressant prescription was common, while the combination use of antidepressants accounted for a small portion. Combination use of antidepressants with one psychotropics (antipsychotics, mood stabilizer, sedative hypnotics) was common, while with two were less frequently occurred. Conclusion Prescriptions of antidepressants for patients with psychosis hospitalized in Shanghai Mental Health Center from 2005 to 2008 are relatively safe and reasonable. Antidepressants of newer generation have been widely used in clinics, and SSRIs have been serving as the major antidepressants.

Objective To observe the efficacy of Jieyu Fuwei Powder in the treatment of patients with functional dyspepsia(FD).Methods A total of 66 patients with chronic FD(type of dishar-mony between liver and stomach)from the outpatient clinic of Hai'an Hospital of Traditional Chinese Medicine were randomly divided into two groups,with 33 cases in each group.Control group was treated with domperidone,while treatment group was treated with Jieyu Fuwei Powder.The total ef-fective rate、scores of traditional Chinese medicine syndromes,levels of serum 5-hydroxytryptamine(5-HT),substance P(SP),gastrin(GAS)and motilin(MTL)as well as the incidence of adverse reactions were compared between the two groups.Volunteers from the two groups after treatment(14 cases in the control group and 13 cases in the treatment group)were recruited to receive outpatient gastroscopy and obtain biopsy tissues for histopathological and immunohistochemical analysis of GAS and MTL.Results The total effective rate in the treatment group was 90.91％,which was signifi-cantly higher than 69.70％in the control group(P＜0.05).After treatment,the scores of symptoms such as pain in both sides of the chest,epigastric fullness,upper abdominal discomfort,belching,heartburn and irritability in the treatment group were significantly lower than those in the control group(P＜0.01).After treatment,the levels of serum 5-HT and SP decreased significantly while the lev-els of MTL and GAS increased significantly in both groups,and the levels of serum 5-HT and SP were significantly lower in the treatment group than those in the control group,while the levels of MTL and GAS were significantly higher in the treatment group than those in the control group(P＜0.05 or P＜0.01).The incidence of adverse reactions was 6.06％(2/33)in the treatment group and 9.09％(3/33)in the control group,with no significant difference between two groups(P＞0.05).Hematoxylin an eosin(HE)staining of biopsy tissues showed no significant difference in pathology between the two groups,and immunohistochemical results suggested that the expression level of GAS and MTL in the treatment group was higher than that in the control group.Conclusion Efficacy of Jieyu Fuwei Powder in the treatment of FD differentiated as type of disharmony between liver and stomach is superior to domperidone,and its mechanism may be related to the intervention of brain-gut interaction.

Objective:To evaluate the feasibility of the screw and plate for clival fixation using a transoral expanded approaches.Methods:The transoral expanded approaches were performed on craniocervical segment specimens obtained from 7 subjects, including transoral approach (TO), transoral with soft (TOP) or hard (TOHP) palate split, mandibulotomy (MO) and mandibuloglossotomy (MLO). The distribution and thickness of soft tissue, the configuration of the vertebral arteries, the distance between the midline and the vertebral arteries, the exposed area of the clivus and cervical spine, and the range of screw angle (the angle between the line from the lower incisor or the central base of the mandible to the exposed area of the clivus and the tangent line of the clivus) were evaluated.Results:The thickness of the soft tissue on the posterior pharyngeal wall above the clival pharyngeal nodules was 3.5±0.6 mm. That on the anterior C 1-C 5 vertebrae was 5.0±0.5 mm. The distances from the bilateral vertebral arteries to the midline was 19.5±1.2 mm at C 1, 2, 14.6±2.7 mm at C 2, 3, 14.0±2.7 mm at C 3, 4, and 13.9±2.7 mm at C 4, 5. For the TO approach, the longitudinal diameter of the exposed clivus was 8.3±3.0 mm. The distance from the lower incisor to the superior margin of the exposed clivus, the lower margin of the exposed clivus, the anterior arch of C 1, the vertebral body of C 2 and C 3 were 104.7±4.3 mm, 99.2±6.8 mm, 81.4±4.3 mm, 75.1±4.0 mm and 68.7±6.5 mm, respectively. Six specimens were exposed to the C 3, while one was exposed to the C 2. For the TOP approach, the longitudinal diameter of the exposed clivus was 18.5±4.8 mm. The distance from the lower incisor to the superior margin of the exposed clivus and the pharyngeal nodules were 107.9±6.7 mm and 104.8±6.7 mm, respectively. For the TOHP approach, the longitudinal diameter of the exposed clivus was 26.3±1.8 mm (the clival length) with distance from the lower incisor to the superior margin of the clivus 112.4±12.6 mm. For the MO/MLO approach, the entire clivus was exposed. The distance from the central base of the mandible to the superior and inferior margin of the exposed clivus and the pharyngeal nodules were 141.8±15.7 mm, 131.0±9.9 mm and 120.5±8.2 mm, respectively. The inferior margin of the exposed cervical vertebra was C 5, 6. The rate of the clival screw placement through anterior occipitocervical fixation using TO, TOP, TOHP, MO and MLO was 0%, 71% (5/7), 86% (6/7), and 100%, respectively. The screw angle was 99.0°±1.8°, 92.6°±7.7°, 92.6°±7.7°, 75.1°±7.7°, and 75.1°±7.7°, respectively. Conclusion:Occipitocervical fixation with clival screw and plate could be conducted in most cases via TOP and TOHP approaches. However, in some cases with small split-mouth or mouth opening limited, smaller clival screw angle caused by basilar impression or basilar invagination, requiring fixation and reconstruction of the lower cervical spine, and the MO/MLO approaches could be still required to achieve the fixation.

Objective:To develop a specialized clival-cervical plate fixation (CCPF) for anterior surgery to treat craniovertebral instability, and to compare it with a posterior occipitocervical fixation (POCF) in biomechanical validation.Methods:Based on the measurement of 40 adult dry bones and 30 volunteers CT images, the clival-cervical plate was designed and manufactured. 8 cadaveric specimens (occiput-C 3) were tested in five conditions including the intact status, the intact+CCPF status, the injury status, the injury+CCPF status, and the injury+POCF status. Specimens were applied a pure moment of 1.5 N·m in flexion, extension, lateral bending, and axial rotation. Calculating and comparing the range of motion (ROM) and neutral zone (NZ) for the occiput to C 2. The effects of different fixation methods on the distribution of ROMs at the occipitocervical region were compared. Results:The injury+CCPF status constrained ROMs to 1.7° in flexion ( q=4.68, P=0.055) , 1.2° in extension ( q=0.39, P=0.9922) , 2.8° in lateral bending ( q=1.25, P=0.814) , and 4.3° in axial rotation ( q=5.08, P=0.035) , resulted in larger ROM in axial rotation but similar ROMs in other directions ( P>0.05) when compared with the injury+POCF status. There were no significant differences between the above two fixation methods in flexion-extension ( q=1.94, P=0.554) , lateral bending ( q=1.79, P=0.611) and axial rotation ( q=2.14, P=0.478) for the NZs. For the flexion, extension,lateral bendingand axial rotation direction, the proportion of the C 1, 2 ROM to the overall ROM was 28%, 25%, 34% and 56% respectively in the injury+CCPF status, and it was 59%, 53%, 42% and 71% respectively in the injury+POCF status. Conclusion:CCPF is a biomechanically effective alternative or supplemental method of POCF for the craniocervical instability.
