Randomized controlled trials of acupuncture and moxibustion for post-stroke constipation: a meta analysis / 中国针灸

The clinical efficacy of acupuncture and moxibustion for post-stroke constipation was systematically reviewed. By computerized and manual retrieval of clinical research literature regarding acupuncture and moxibustion for post-stroke constipation, the randomized control trials (RCTs) that met the inclusive criteria were collected. Cochrane systematic review method was used and Revmen 5.2 software was adopted to perform this Meta analysis. Totally 8 articles were included, involving 610 cases of post-stroke constipation. As a result, the total effective rate and cured rate of acupuncture and moxibustion for post-stroke constipation were significantly superior to those of the control group [total effective rate: OR = 2.10, 95% CI (1.25, 3.54), Z = 2.78, P = 0.005; cured rate: OR = 2.37, 95% CI (1.57, 3.58), Z = 4.10, P < 0.0001]. This result indicated that acupuncture was effective for post-stroke constipation and had some advantages compared with other therapies. But the quality of included RCTs was low, and high-quality, large-sample and multi-center RCTs were needed to perform further verification.

The role of third-party tolerogenic dendritic cells in the prevention of acute graft-versus-host-disease following allogeneic bone marrow transplantation in mice / 中华血液学杂志

<p><b>OBJECTIVE</b>To explore the biological characteristic of third-party-derived tolerogenic DC(tDC) and the influence of third-party-derived tDC on acute graft-versus-host-disease (aGVHD) following allogeneic bone marrow transplantation (allo-BMT) in mice.</p><p><b>METHODS</b>tDC from bone marrow cells of D1 mice was cultured with low doses of GM-CSF, IL-10 and TGF-β1D1. The phenotype, expression of cytokines and function associated molecules were identified with FACS and RT-PCR. Mixed lymphocyte reaction was applied to analyze the influence of third-party-derived tDC on allo-CD4(+)T cells proliferation in vitro. Different doses of D1-tDC were adoptive transferred in the aGVHD model in allogeneic BMT which B6 mice as donors and D2 mice as recipients. Survival time, clinical GVHD score and the levels of Th1/2 cytokines in serum were monitored after allo-BMT using the aGVHD model as control.</p><p><b>RESULTS</b>tDC expressed lower levels of MHC II and co-stimulatory molecules, such as CD80, CD86 and CD40, even when stimulated by LPS. The results by RT-PCR indicated that tDC expressed low levels of IL-12p40 and high levels of immunosuppressive molecules, such as IL-10, TGF-β, Fas Ligand, indoleamine 2, 3-dioxygenase (IDO) and arginase. In the allogeneic MLR, third-party tDC suppressed allo-CD4(+)T cells proliferation, which was relative to the dose of tDC. In the B6→D2 mouse model, all aGVHD mice died within 18 days. Remarkably, if 10(4) third-party tDC were transferred, 60% mice survived at least 60 days. When the doses of tDC were reduced to 10(3) cells, only 20% of mice survived day 60, and when increased tDC to 10(5), all of the mice died within day 37 after allo-BMT. The cytokine levels in serum indicated that 10(4) tDC-treated mice secreted in vivo high level of IL-10 21d after BMT (P < 0.05), the levels of IL-10 in 10(3), 10(4) and 10(5) tDC-treated mice were (114.23 ± 7.78), (646.18 ± 212.02), (121.97 ± 10.47) ng/L, respectively.</p><p><b>CONCLUSION</b>Third-party tDC could suppress allo-CD4(+)T cells proliferation in vitro and prevent aGVHD in allogeneic BMT mode, which may be mediated by modulating tolerogenic cytokines secretion, such as IL-10. And this effect was associated with the dose of tDC. Adoptive therapy by transfusing third-party tDC cultured with low doses of GM-CSF, IL-10 and TGF-β1 could significantly prolong the survival of recipients and prevent aGVHD in allogeneic BMT.</p>

<p><b>OBJECTIVE</b>To explore the best intervention time of acupuncture and moxibustion for peripheral facial palsy (Bell's palsy) and the clinical advantage program of selective treatment with acupuncture and moxibustion.</p><p><b>METHODS</b>Multi-central large-sample randomized controlled trial was carried out. Nine hundreds cases of Bell's palsy were randomized into 5 treatment groups, named selective filiform needle group (group A), selective acupuncture + moxibustion group (group B), selective acupuncture + electroacupuncture (group C), selective acupuncture + line-up needling on muscle region of meridian group (group D) and non-selective filiform needle group (group E). Four sessions of treatment were required in each group. Separately, during the enrollment, after 4 sessions of treatment, in 1 month and 3 months of follow-up after treatment, House-Brackmann Scale, Facial Disability Index Scale and Degree of Facial Nerve Paralysis (NFNP) were adopted for efficacy assessment. And the efficacy systematic analysis was provided in view of the intervention time and nerve localization of disease separately.</p><p><b>RESULTS</b>The curative rates of intervention in acute stage and resting stage were 50.1% (223/445) and 52.1% (162/311), which were superior to recovery stage (25.9%, 35/135) separately. There were no statistical significant differences in efficacy in comparison among 5 treatment programs at the same stage (all P > 0.05). The efficacy of intervention of group A and group E in acute stage was superior to that in recovery stage (both P < 0.01). The difference was significant statistically between the efficacy on the localization above chorda tympani nerve and that on the localization below the nerve in group D (P < 0.01). The efficacy on the localization below chorda tympani nerve was superior to the localization above the nerve.</p><p><b>CONCLUSION</b>The best intervention time for the treatment of Bell's palsy is in acute stage and resting stage, meaning 1 to 3 weeks after occurrence. All of the 5 treatment programs are advantageous to Bell's palsy. In the condition of the limited medical sources, the simple filiform needle therapy is recommended in acute stage. For the patients with the disorder above chorda tympani nerve, the line-up needling on muscle region of meridian is not recommended.</p>
