Objective To compare the efficacy of using“distal acupoints only”vs.“local acupoints mainly combined with distal acupoints”in cases of acute low back pain(ALBP).Methods A total of 102 eligible patients aged 18–65 years with ALBP lasting less than 6 weeks will be randomized in a 1:1 ratio to the distal acupoints only group(DPOg)and the local acupoints mainly combined with the distal acupoints group(LPMg).During a 4-week treatment period,patients in the DPOg will receive acupuncture at distal acupoints only(Houxi[SI 3]and yaotongxue[EX-UE 7])twice a week,while those in the LPMg group will receive acupuncture at local acupoints(mainly Shenshu[BL 23]and Dachangshu[BL 25])combined with distal points(Weizh.ng[BL 40]).The patients in both groups will be evaluated at every session of treatment,and the follow-up will be performed for 3 *** primary outcome measure will be the change in ALBP intensity,assessed using visual analogue scale scores before and after *** secondary outcome measure will be the evaluation of functional disability using the Oswestry Disability *** This study compares the DPOg and LPMg to explore the feasibility of the DPOg in the treatment of ALBP.

A mechanism for the catalytically growth of vapor grown fibrous carbon (VgfC) preparing from the floating catalyst method has been proposed, in which liquid diffusion-determined diffusion of carbon atoms through catalyst particles is described mathematically, and the physical and chemical properties of the catalyst particles during the growth process are taken into account. from the model the growth rate and grown length of VgfC are calculated theoretically which coincides with the experimental data; and the necessity of reducing gas such as hydrogen in preparing VgfC is explained as to reduce fe3C, which acts as intermediate catalyst shown by the model. fe3C formed on the surface of gamma-fe will stop the growth of carbon fiber if they can not be reduced at once. Additionally, the growth temperature and diameter of VgfC are also discussed in the paper.

There is growing recognition that neutrophils play an important role in cancer initiation, progression and metastasis. Although they are typically characterized as short-lived effector cells, neutrophils have been shown to acquire immunosuppressive and pro-tumorigenic functions that promote tumor progression and escape. As such, inhibition of their function or depletion of neutrophils are being explored as potential cancer therapies. However, growing evidence of neutrophil diversification in cancer and their potential anti-tumor roles raise many unresolved questions. Here, we review recent advances that address the definition,origin and function of neutrophils in cancer, and elaborate on obstacles that make the study of neutrophils challenging. We envision that this review will provide the groundwork for focused design of therapeutics that will specifically target "tumorreprogrammed" neutrophils while sparing normal neutrophils to improve patient outcomes.
