Objective To observe the clinical efficacy of triple needling and centro-square needling in treating hemifacial spasm. Method Sixty-eight patients with facial spasm were randomized into a treatment group and a control group, 34 in each group. The treatment group was intervened by centro-square needling at topical Ashi points and triple needling at Yifeng (TE 17) on the affected side; the control group was intervened by regular acupuncture. The two groups were treated once a day, 10 times as a treatment course, for 3 courses in total. Cohen Albert grading scale was adopted to evaluate the spasm intensity before and after the intervention, and the clinical efficacies were then compared.Result After intervention, there was a significant difference in comparing the spasm intensity between the two groups (P<0.05). The significant improvement rate was 88.2% in the treatment group versus 50.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Triple needling plus centro-square needling is an effective method in treating hemifacial spasm. This method uses less points, but it produces a high efficacy, strong pertinence, and is easy-to-operate.

Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

Objective To investigate the expression of microRNA-34a (miR-34a) and silent information regulator 1 (SIRT1) in human lens epithelial cells under H2O2-induced oxidative stress.Methods Different concentrations of H2O2 (0 μmol · L-1,100 μ mol· L-1,200 μmol · L-1,300 μmol · L-1,and 400 μmol · L-1) were used to stimulate SRA01/04 cells for 24 hours.Cell viability was measured using cell counting kit-8 (CCK-8) assay.Cell apoptosis was detected by flow cytometry.Expression levels of miR-34a/SIRT1 were measured by RT-PCR.Results CCK-8 assay showed that a certain concentration range of H2O2 had a proliferation inhibition on SRA01/04 cells.There was a dose response relationship between 100 μmol · L-1 and 400 μmol · L-1.Compared with 0 μmol · L-1 H2O2 group,the difference was statistically significant (all P ＜ 0.01).According to flow cytometry results,apoptotic rate of SRA01/04 cells in control group and H2O2(100-300 μmol · L-1) groups were (6.1 ± 1.2)％,(26.3 ± 1.8)％,(32.5 ± 2.2) ％,and (64.7 ± 5.3) ％.Compared with 0 μmol · L-1 H2 O2 group,the differences were statistically significant (all P ＜ 0.01).RT-PCR test results showed that the expression of miR-34a increased significantly in a dose-dependent manner after the SRA01/04 cells treated with different concentrations of H2O2,while SIRT1 expression level was decreased,there were significant differences compared with control group (all P ＜ 0.001).Conclusion There is a significantly increase of miR-34a and decrease of SIRT1 in human lens epithelial cells under the oxidative stress of a certain concentration of H2O2.Down-regulated expression of miR-34a can increase the survival rate of human lens epithelial cells under H2O2-induced oxidative stress.

Objective To observe the clinical effect of Biafine cream to prevent acute irradiation-induced dermal injury. Methods 104 patients who had to accept radiotherapy were randomized into two groups:treatment group(56 cases) was give Biafine cream application since the first radiotherapy session while the other 48 served as control without this medication when general and health education program was given. Results Dermal toxic rate and degree in the treatment group were obviously lower than those of the control group, with the difference between the two groups significant. Conclusions Biafine cream can effectively prevent acute irradiation-induced dermal injury. It can alleviate the patients' suffering and improve their quality of life, so as to ensure uneventful radiotherapy .
