Objective To investigate the effect of curcumin on Aβ production in swAPP HEK293 cells and its preliminary mechanism.Methods swAPP HEK293 was used as cell model,the effect of curcumin (at different time points and of concentration) on cell viability was accessed by MTT assay.After the cells were treated with non-cytotoxic concentration of 5 μmol/L for different time,ELISA was used to detect Aβ production.The concentration and the time point of the strongest inhibitory effect were selected for the following tests.Real time PCR was employed to analyze miR-153 and APP mRNA expression,and Western blot was used to detect APP protein expression.Results As compared with the control group,curcumin of ≤ 5 μmol/L had no toxicity effect on the cell viability (P > 0.05).Curcumin significantly inhibited Aβ production (P < 0.05).Therefore 5 μmol/L curcumin and 24 h were selected as the best concentration and timc.Curcumin of 5 μmol/L had no obvious impact on APP mRNA expression (P < 0.05),whereas markedly decreased APP protein expression.In addition,miR-153 level in the cells was significantly increased by 5 μmol/L curcumin treatment (P < 0.05).Conclusion Curcumin may inhibit Aβ production through up-rcgulating miR-153 level and reducing APP protein expression in swAPP HEK293 cells.

To explore the application of gene chip technology in the acupuncture research so as to provide evidences for the mechanism of acupuncture for regulating bodies. The literature on the application of gene chip technology in the acupuncture field from 2001 to 2016 was collected in PubMed, Springer, CNKI and WANFANG databases, which was analyzed and summarized. There were some achievements of the technology for acupuncture research, focusing on the five aspects, including the study of the relationship between meridian-point and viscera, the influencing factors of acupuncture effect, the effect and mechanism of acupuncture analgesia, the mechanism of acupuncture anti-aging, the effect and mechanism of acupuncture for diseases of each system. Gene chip technology plays an important role in researching acupuncture mechanism. It is an important technology for genomics study of acupuncture. However, there are also some disadvantages such as high cost, deficient data mining, non-uniform observation objects, deficient professionals, etc. All those need further resolution so as to promote the application of this technology in the acupuncture researching field.

There are various contents about diagnosis and treatment of low back pain in(), which are closely related to meridians and collaterals, forming a complete theoretical system of meridian differentiation for low back pain. Its theory and application are interpreted in this paper from five main aspects, including 18 meridians and collaterals densely distributing in the tendons and bones of the waist, the pathogenesis of low back pain lying in the disorders of the meridianand blood, the nature of low back pain being reflected by the color and shape of meridians and collaterals, the disordered meridians of low back pain being first identified based on syndrome differentiation, the acupuncture prescription being selected according to meridian differentiation. The purpose of this paper is to guide clinical practice, explore the advantages and characteristics of meridian differentiation, and provide theoretical reference and evidence for promoting the standardization of TCM.
