RESUMO
Objective To evaluate the effects of acupuncture combined with lifestyle modification for essential hypertension by Meta-analysis. Methods Clinical randomized controlled trial literature about acupuncture combined with lifestyle modification for essential hypertension in CNKI, WanFang Data, CBM, VIP, PubMed, Embase, and Web of Science since establishment to February 20, 2017 were retrieved. Data extraction and quality assessment of studies were conducted by two researchers independently, and the Meta-analysis was performed by the software of RevMan5.3. Results 5 articles involving 467 patients were included. The results of Meta-analysis showed that acupuncture combined with lifestyle modification had more significant effect than lifestyle modification alone in lowing SBP [SMD=-1.52(-2.40,-0.64)], in lowing DBP [SMD=-1.02(-2.01,-0.03)], total effective rates [RR=1.27(1.13, 1.43)]. Conclusion Compared with lifestyle modification alone, acupuncture combined with lifestyle modification have significant effects for patients with essential hypertension, but because of the fewer studies included, bigger heterogeneity between studies and the lower quality of included studies still exist, the results should be further verified, and clinical applications should be treated with caution.
RESUMO
<p><b>BACKGROUND</b>To evaluate whether serotonin (5-HT), 5-HT2A receptor (5-HT2AR), and 5-HT transporter (serotonin transporter [SERT]) are associated with different disease states of depression, myocardial infarction (MI) and MI co-exist with depression in Sprague-Dawley rats.</p><p><b>METHODS</b>After established the animal model of four groups include control, depression, MI and MI with depression, we measured 5-HT, 5-HT2AR and SERT from serum and platelet lysate.</p><p><b>RESULTS</b>The serum concentration of 5-HT in depression rats decreased significantly compared with the control group (303.25 ± 9.99 vs. 352.98 ± 13.73; P = 0.000), while that in MI group increased (381.78 ± 14.17 vs. 352.98 ± 13.73; P = 0.000). However, the depression + MI group had no change compared with control group (360.62 ± 11.40 vs. 352.98 ± 13.73; P = 0.036). The changes of the platelet concentration of 5-HT in the depression, MI, and depression + MI group were different from that of serum. The levels of 5-HT in above three groups were lower than that in the control group (380.40 ± 17.90, 387.75 ± 22.28, 246.40 ± 18.99 vs. 500.29 ± 20.91; P = 0.000). The platelet lysate concentration of 5-HT2AR increased in depression group, MI group, and depression + MI group compared with the control group (370.75 ± 14.75, 393.47 ± 15.73, 446.66 ± 18.86 vs. 273.66 ± 16.90; P = 0.000). The serum and platelet concentration of SERT in the depression group, MI group and depression + MI group were all increased compared with the control group (527.51 ± 28.32, 602.02 ± 23.32, 734.76 ± 29.59 vs. 490.56 ± 16.90; P = 0.047, P = 0.000, P = 0.000 in each and 906.38 ± 51.84, 897.33 ± 60.34, 1030.17 ± 58.73 vs. 708.62 ± 51.15; P = 0.000 in each).</p><p><b>CONCLUSIONS</b>The concentration of 5-HT2AR in platelet lysate and SERT in serum and platelet may be involved in the pathway of MI with depression. Further studies should examine whether elevated 5-HT2AR and SERT may contribute to the biomarker in MI patients with depression.</p>
