Objective To observe the effect of heat-producing needling (Shao Shan Huo) and cool-inducing needling (Tou Tian Liang) on the gait cycle after operation for gluteus contracture. Method Sixty-six patients after operation for gluteus contracture were randomized into a treatment group and a control group, 33 in each group. The control group was intervened by rehabilitation, while the treatment group was by acupuncture in addition to the rehabilitation training. The topical points Zhibian (BL 54), Huantiao (GB 30), and Juliao (GB 29) were treated with reducing cool-inducing needling technique; Biguan (ST 31), Futu (ST 32), Zusanli (ST 36), Fenglong (ST 40), Xuehai (SP 10), Diji (SP 8), and Yanglingquan (GB 34) were treated with reinforcing heat-producing needling technique. The motor time parameters were observed before and after intervention.Result After intervention, the supporting phase of the affected side, supporting phase of the healthy side, gait cycle, swinging phase of the affected side, swinging phase of the healthy side, and bilateral supporting phase of the treatment group were significantly different from that of the control group (P<0.05).Conclusion Heat-producing and cool-inducing needling techniques can effectively shorten the gait cycle after operation for gluteus contracture, and can improve the walk function.

Objective To study the influence of artesunate (Akt) on the proliferation and apoptosis of human head and neck squamous cell carcinoma (HNSCC), and to explore its molecular mechanism thereof. Methods The HNSCC cell line,UM-SCC-10A cells, was cultured in vitro. The Inhibitory concentration 50 (IC50) was examined by MTT assay. The cell mor?phological changes were observed under inverted light micro-scope after being interfered by 0, 2.5, 5, 10, 20 and 40μmol/L Akt. Cell cycle changes and apoptosis were measured by flow cytometry. And the expression of cell cycle regulators and apop?totic associated protein were detected by Western blot assay. Results MTT assay demonstrated that Akt significantly inhib?ited the proliferation of UM-SCC-10A cells in dose-dependent manner. After UM-SCC-10A cells were treated with Akt for 48 h, IC50 was 15.01μmol/L. Morphological changes of cell apoptosis such as karyopyknosis and conglomeration were ob?served by Hoechst 33258 staining. Flow cytometry showed that the apoptosis was associated with cell cycle arrest during the G1 phase. Western blot analysis showed that p53 and p21 protein was up-regulated and Cyclin D protein was down-regulat?ed. Furthermore, results revealed that Bcl-2 associated X protein induced by a mitochondrial pathway, cytochrome C and caspase-3 were up-regulated, and Bcl-2 and procaspase-3 were down-regulated. The mitochondrial membrane potential was reduced. Conclusion Artesunate can induce apoptosis of UM-SCC-10A cells via a mitochondrial pathway, which was associated with cell cycle arrest in the G1 phase. As a result, artesunate has an obvious inhibitory effects on proliferation of UM-SCC-10A cells.

Long non-coding RNAs (lncRNAs) are a group of regulatory and non-coding RNA molecules which are longer than 200 nucleotides. They are involved in a variety of biological processes such as cell proliferation, differentiation and apoptosis mainly by regulation of gene expression at various levels, including epigenetics, transcription and post-transcription. The evidence has demonstrated that many lncRNAs are dysregulated and closely related to tumorigenesis, progression and prognosis in gastric cancer. Based on an introduction to lncRNAs and the domestic and foreign research status, this review summarizes the function, regulatory mechanisms, potential diagnostic and therapeutic values of lncRNAs in gastric cancer.
