Aim To investigate the neuroprotective effect of acteoside against rotenone-induced cell damage in SH-SY5Y cells and the effect of acteoside on the expression of Parkinson disease (PD)-related proteins Parkin and ?-Synuclein(?-Syn), and to discover the underlying molecular mechanism of neuroprotection by acteoside. Methods The activity of lactate dehydrogenase(LDH) was measured by spectroscopy. Expressions of Parkin and ?-Syn were studied using Western blot analysis, and the distribution of ?-Syn was analyzed using immunofluorescence technique. Results ① Acteoside (10, 20 or 40 mg?L-1) pretreatment for 6 h markedly reduced the release of LDH induced by 0.5 ?mol ?L-1 rotenone; ② Treatment with 0.5 ?mol?L-1 rotenone for 48 h led to significant Parkin cleavage and increased formation of ?-Syn protein dimer; ③ Pretreatment of SH-SY5Y cells with acteoside (10, 20 or 40 mg?L-1) for 6 h markedly reduced the cleavage of Parkin induced by 0.5 ?mol?L-1 rotenone in a concentration-dependent manner, inhibited the aggregation of ?-Syn and decreased ?-Syn-positive SH-SY5Y cells. Conclusion These findings suggest that pretreatment of acteoside has a potent neuroprotective effect against rotenone-induced SH-SY5Y cells damage and its mechanism might involve in reducing the cleavage of Parkin and inhibitng ?-Syn expression induced by rotenone.

Functional multineuron calcium imaging(fMCI)is an optical recording technique to monitor neuron population action potentials in the spatiotemporal pattern by recording calcium signal changes in neurons.The review describes the technology of fMCI and its application prospect in neuropharmacology research.fMCI provides a kind of powerful tool to analyze various functions of brain and to research some central nervous system drug mechanism based on neural network.

Memory disorders is the commonest cognitive impairment of people with traumatic brain injury, cerebral vascular disease, senile dementia and so on. Recently researchers at home and abroad used different rehabilitation training methods to treat the memory disorders in patients with brain injury, and has made some progress. This study reviewed the methods and efficacy of recent rehabilitation about memory disorders, and discussed the optimum rehabilitation programs.

Objective To investigate the clinical efficacy of target fire red-hot needling in treating articular deformity due to rheumatoid arthritis.Methods Ninety-six rheumatoid arthritis patients with articular swelling and deformity were randomly allocated to treatment and control groups, 48 cases each. The treatment group received target scattered fire red-hot needling and the control group, conventional acupuncture. After two courses of treatment, pre-/post-treatment changes in the self-reported pain score, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and immunoglobulins (IgA, IgG and IgM) were observed in the two groups and the clinical therapeutic effects were compared between the two groups. Results The total efficacy rate was 89.6% in the treatment group and 50.0% in the control group; there was a statistically significant difference between the two groups (P<0.01). There were statistically significant pre-/post-treatment differences in ESR, CRP, IgA, IgG and IgM in the treatment groups (P<0.05). There were statistically significant pre-/post-treatment differences in ESR, CRP, and IgG in the treatment groups (P<0.05). There were statistically significant post-treatment differences in ESR, CRP, IgA, IgG and IgM in the treatment and control groups (P<0.05).Conclusion Target fire red-hot needling is an effective way to treat articular deformity due to rheumatoid arthritis.

Objective To investigate the expression pattern of STIL in gastric cancer and effect of silencing STIL on biological behaviors of SGC-7901 cell line.Methods The expression of STIL at mRNA and protein level were detected by qPCR and Western Blot,respectively.SiRNA against STIL was constructed and transfected into SGC-7901 cell line.The effect of Si-STIL on cell proliferation,cloning ability,cycle distribution and apoptosis was detected by MTT,colony-forming assay and flow cytometry,respectively.Results STIL was aberrantly expressed in gastric cancer compared with that in paratumor tissues.Downregulation of STIL level,inhibition of proliferation and cloning ability,increasing apoptosis and blocked cell cycle at S phase were observed after SGC-7901 cell line was treated with Si-STIL.Conclusion STIL was overexpressed in gastric cancer.STIL gene silencing effectively inhibited cell growth,transition of metaphase and promoted apoptosis of SGC-7901 cell line.

28.5 ?mol/L) and liver function. Results Among 1275 women, 102 were diagnosed with ICP giving an incidence of 8.0%. The incidence was significantly higher during 33 to 36 weeks (18.80%, P

Objective To explore the value of the square for intracranial puncture orientation applying in the intracranial hematoma microinvasive craniopuncture scavenging technique. Methods Fifty-one patients with hypertensive cerebral hemorrhage were randomly enrolled into the orientation square group( n=27)and the CT orientation routine group (n=24). The puncture point was fixed by certain wayin each group. Both groups received the same intracranial hematoma microinvasive craniopuncture scavenging technique. The punctural precision,the time spended for puncture orientation and the curative effect in two group were observed and compared. Results The deflected rate(18.5%)of the orientation square group was lower than that routine group significantly(50.0%)(P

Objective To evaluate the effectiveness of allergen specific immunotherapy (SIT) in the treatment of allergic rhinitis. Methods A total of 132 patients with seasonal ragweed allergic rhinitis were enrolled in this study. The patients were randomly divided into two groups. SIT group, in which 68 patients were treated with ragweed SIT for six months before July for 3 years. ST (symptomatic therapy) group, in which 64 patients were treated with ST during seasonal symptomatic period. The healthy control group included 40 subjects. The levels of serum total IgE (tIgE), specific IgE (sIgE), ECP, IgG and IL-4, IL-5, IFN-? were measured, and eosinophil numbers were counted. The symptom score, lung-function test and skin prick test were performed before and after the treatment. Results The elevated levels of tIgE, ECP, IL-4, IL-5 in the sera and eosinophil counts in peripheral blood of the patients were significantly reduced, whereas the levels of IgG and IFN-? were increased following SIT. The levels of serum sIgE were not changed in both SIT and ST groups. 30.88% of the patients were clinically cured, the effective rate was 41.18%, the improvement rate was 20.59% after SIT, and only in 7.39% of patients there was no clinical improvement. In 16.18% of patients there were mild side effects to SIT. In the ST group, there was on change in all the laboratory results and clinical symptoms, and 25% of the patients developed asthma. Conclusion SIT was able to improve the symptoms and laboratory results of the patients with allergic rhinitis. The results indicated that SIT may be an effective and safe therapy for patients with allergic rhinitis.
