Objective To study the effects ofShenqi YizhiGranules (SQYZ) on learning and memory and content of Aβ1-42 of cerebral tissue in 5XFAD mice with Alzheimer’s disease; To discuss its mechanism on improving learning and memory ability of 5XFAD mice.Methods Four-month-old C57BL?6 wild type mice were randomly divided into NS control group and SQYZ control group, and the 5XFAD mice were randomly divided into model group, SQYZ group and huperzine-A (HupA) group, 15 mice in each group. Each group were given same volume for gavage for 60 d. After treatment, the learning and memory ability were evaluated by nesting test, passive avoidance and Morris water maze test. The senile plaques and content of Aβ1-42, ionized calcium binding adapter molecule 1 and glial fibrillary acidic protein in cerebral cortex and hippocampus were detected by immunohistochemical staining and immunofluorescence, respectively.Results Compared with NS control group, the score of nesting test in model group significantly decreased; the step-through latency in passive avoidance was shortened and the escape latentcy in Morris water maze test was prolonged; the quantity of senile plaques and content of Aβ1-42 increased in cerebral cortex and hippocampus; the activation of glial cells significantly increased. In the SQYZ group, the above-mentioned indexes reached or approached the level of wild type control mice. The difference between SQYZ group and model group was statistically significant (P<0.05,P<0.01).Conclusion SQYZ improved learning and memory ability in 5XFAD mice, which may be related to reduction of senile plaques, inhibition of over activation in glial cells and reduction of content of Aβ1-42 in cerebral cortex and hippocampus.

ObjectiveTo explore the new rehabilitation model of medication combined with education of cerebral palsy.MethodsThe cross-professionals were organized to assess and observe 126 children with cerebral palsy. Then, individual education plan (IEP) combined with medication, family, feeding was made and performed.ResultsAfter educational rehabilitation, the children with cerebral palsy got improvement in intellection, social adaptation, communion aspiration, thinking and etc. They became more cooperated in medical rehabilitation.ConclusionInterdisciplinary cooperation, IEP, participation of parents are the conditions for success of medical rehabilitation combined with education.

Objective To compare the clinical and radiological outcomes between hybrid and total pedicle screw instrumentation in adolescents undergone posterior spinal fusion (PSF) for thoracic scoliosis secondary to Chiari malformation..Methods A total of 75 patients undergone PSF were included and divided into two groups:the all pedicle screw group (Group A,n=44) and the hybrid group (Group B,n=31).Patients were evaluated before surgery,immediately after surgery,and at the 2-year follow-up in radiographic changes in curve magnitude,apical vertebral translation (AVT),apical vertebral rotation (AVR),trunk shift,thoracic kyphosis (TK),lumbar lordosis (LL),and sagittal vertical axis (SVA).These parameters were further analyzed with respect to preoperative TK in both groups.Results After surgery,the average correction of the thoracic curve was 60.2％ and 51.3％ in Group A and B,respectively (t=2.372,P=0.023).The average lumbar curve correction was 61.7％ in Group A,representing a significant increase compared to Group B (51.1％,t=2.431,P=0.020).At the final follow-up,loss of the thoracic curve correction was less in Group A (0.3％) than in Group B (1.7％),however,there was no statistical significance (t=-0.468,P＞0.05).AVT of the thoracic curve improved in Group A from 25.0 mm to 6.9 mm,while in Group B it changed from 24.1 mm to 7.4 mm.For patients with a preoperative TK greater than 40°,the proximal junctional angle was found to be significantly larger in Group A (10.0 degrees versus 4.5 degrees,t=-2.031,P=0.052) by the final follow-up,along with a significantly increased incidence of proximal junctional kyphosis (20％ versus 9％).Conclusion Total pedicle screw instrumentation provided a significantly better correction of the major and minor curves than hybrid constructs for the operative treatment of thoracic scoliosis secondary to Chiari malformation.However,for patients with thoracic hyperkyphosis,all-screw instrumentation had a higher risk of adjacent level proximal kyphosis.

OBJECTIVETo observe the effect of Buyang Huanwu Decoction (BYHWD), a representative formula of qi benefiting blood activating method on aorta Rho associated coiled-coil forming protein serine/threonine kinase (Rhokinase, ROCK) and nuclear transcription factor kappa B (NF-κB) p65 mRNA expressions and levels of blood lipids in atherosclerosis (AS) model rats.

METHODSThe AS rat model was prepared by vitamin D3 and high fat diet. Totally 60 rats were randomly divided into 6 groups, i.e., the normal control group, the model group, the low dose BYHWD group (10 g/kg), the high dose BYHWD group (20 g/kg), the Simvastatin control group (0.6 mg/kg), and the BYHWD prevention group (10 g/kg), 10 in each group. After successful modeling all medication was intervened for 28 days. Expression levels oxidized low density lipoprotein (ox-LDL) were detected by ELISA. Levels of TG, TC, LDL-C, HDL-C were determined by enzyme method. Pathological changes of aortic tissue were observed under light microscope. mRNA expressions of Rho kinase and NF-κB p65 in aorta were detected by real time (RT) PCR.

RESULTSHigh fat diet and peritoneal injection of vitamin D3 could induce AS rat model. Typical atheromatous plaque formed in aorta of AS model rats. Compared with the normal control group, levels of TC, TG, LDL-C, and ox-LDL significantly increased in the model group, but the HDL-C level decreased (P < 0.01). Compared with the model group, levels of TC, TG, LDL-C, and ox-LDL all decreased, but HDL-C increased in low and high dose BYHWD groups, the Simvastatin control group, and the BYHWD prevention group (P < 0.05, P < 0.01). Compared with the low dose BYHWD group, above-mentioned indices were more obviously lowered in the high dose BYHWD group, the Simvastatin control group, and the BYHWD prevention group (P < 0.05). Compared with the normal control group, mRNA expression levels of Rho kinase and NF-κB p65 significantly increased in the model group (P < 0.01). Compared with the model group, mRNA expressions of Rho kinase and NF-κB p65 obviously decreased in low and high dose BYHWD groups, the Simvastatin control group, and the BYHWD prevention group (P < 0.01). Compared with the low dose BYHWD group, the two indicators were more obviously lowered in the high dose BYHWD group, the Simvastatin control group, and the BYHWD prevention group (P < 0.05). But there was no statistical difference in blood lipids levels, mRNA expression levels of Rho kinase or NF-κB p65 among the high dose BYHWD group, the Simvastatin control group, and the BYHWD prevention group (P >0. 05).

CONCLUSIONSBYHWD could down-regulate mRNA expression levels of Rho kinase and NF-κB p65, lower levels of blood lipids, and fight against AS. Suppressing Rho kinase pathway might be one of its mechanisms.

Objective To explore the etiopathogenisis of fungal infections induced by systemic lupus erythematosus (SLE). Methods One hundred and forty-seven SLE patients with fungal infections during 2004-2013 were assigned as experimental group and the same number of SLE patients without infections were randomly selected as control group. Clinical and laboratory documents of these patients were comparatively analyzed. Results The fungal infections in SLE patients affected oral mucosa , lower respiratory tract and skin , and the pathogenic bacteria were mainly candida albicans. The wide application of glucocorticoid, immunosuppressants and antibiotics pushed the rise of incidence of fungal infections in SLE patients significantly. Conclusions The patients′ use of glucocorticoid , immunosuppressants and antibiotics attributes to a higher risk of fungal infections , especially infections by candida albicans. Fungus infection may raise the level of C4.
