Analgesic Effect of Moxibustion with Different Temperature on Inflammatory and Neuropathic Pain Mice

Zhou W1,2, et al.

The aim of this study was to determine whether variation of temperature during moxibustion would generate division of analgesic effect. The moxibustion with different temperatures (37C, 42C, 47C, and 52C) was applied to ST36 acupoint for 30 minutes in chronic inflammatory or neuropathic pain mice. The analgesic effect was evaluated by thermal hyperalgesia test in chronic inflammatory pain and by mechanical allodynia in neuropathic pain, respectively. The results indicated that interventions of moxibustion with different temperature caused different analgesic effect on either chronic inflammatory induced by injection of complete Freund's adjuvant (CFA) or neuropathic pain induced by spared nerve injury (SNI). In chronic inflammatory pain, different moxibustion temperature generated different intensity of analgesic effect: the higher the better. In chronic neuropathic pain, stronger analgesic effect was found in moxibustion with temperature 47C or 52C other than 37C and 42C. However, there is no significant difference displayed between moxibustion temperatures 47C and 52C or 37C and 42C. It implies that the temperature should be taken into account for moxibustion treatment to chronic inflammatory or neuropathic pain.

Anticancer Activity of Astragalus Polysaccharide in Human Non-Small Cell Lung Cancer Cells

Wu CY1, et al.

Background: We have reported that Chinese herbs Astragalus polysaccharide (APS) can inhibit nuclear factor kappaB (NF-κB) activity during the development of diabetic nephropathy in mice. NF-κB plays important roles in genesis, growth, development and metastasis of cancer. NF-κB is also involved in the development of treatment resistance in tumors. Here we investigated the antitumor activity of APS in human non-small cell lung cells (A549 and NCI-H358) and the related mechanisms of action.
Methods: The dose-effect and time-effect of antitumor of APS were determined in human lung cancer cell line A549 and NCI-H358. The inhibition effect of APS on the P65 mRNA and protein was detected by reverse transcriptase-PCR (RT-PCR) and Western blot in A549 cells respectively. The inhibition effect of APS on the p50, CyclinD1 and Bcl-xL protein was detected by Western blot in A549 cells respectively. The effect of APS on NF-κB transcription activity was measured with NF-κB luciferase detection. Finally, the nude mice A549 xenograft was introduced to confirm the antitumor activity of APS in vivo.
Results: Cell viability detection results indicated that APS can inhibit the proliferation of human lung cancer cell line A549 and NCI-H358 in the concentration of 20 and 40 mg/mL. NF-κB activator Phorbol 12-myristate13-acetate (PMA) can attenuate the antitumor activity of APS in both cell lines, but NF-κB inhibitor BAY 11-7082 (Bay) can enhance the effect of APS in both cell lines. In vivo APS can delay the growth of A549 xenograft in BALB/C nude mice. APS can down-regulate the expression of P65 mRNA and protein of A549 cells and decrease the expression of p50, CyclinD1 and Bcl-xL protein. The luciferase detection showed that the APS could reduce the P65 transcription activity in A549 cells. PMA can partially alleviate the inhibition activity of P65 transcription activity of APS in A549 cells, and Bay can enhance the down-regulation of the P65 transcription activity induced by APS in A549 cells.
Conclusion: APS has a significant antitumor activity in human lung cancer cells A549 and NCI-H358. NF-κB inhibition may mediate the antitumor effect.

Therapeutic Effect of Chinese Herbal Medicines for Post Stroke Recovery

Han SY1, et al.

BACKGROUND: Stroke is a condition with high morbidity and mortality, and 75% of stroke survivors lose their ability to work. Stroke is a burden to the family and society. The purpose of this study was to evaluate the effectiveness of Chinese herbal patent medicines in the treatment of patients after the acute phase of a stroke.
METHODS: We searched the following databases through August 2016: PubMed, Embase, Cochrane library, China Knowledge Resource Integrated Database (CNKI), China Science Periodical Database (CSPD), and China Biology Medicine disc (CBMdisc) for studies that evaluated Chinese herbal patent medicines for post stroke recovery. A random-effect model was used to pool therapeutic effects of Chinese herbal patent medicines on stroke recovery. Network meta-analysis was used to rank the treatment for each Chinese herbal patent medicine.
RESULTS: In our meta-analysis, we evaluated 28 trials that included 2780 patients. Chinese herbal patent medicines were effective in promoting recovery after stroke (OR, 3.03; 95% CI: 2.53-3.64; P < .001). Chinese herbal patent medicines significantly improved neurological function defect scores when compared with the controls (standard mean difference [SMD], -0.89; 95% CI, -1.44 to -0.35; P = .001). Chinese herbal patent medicines significantly improved the Barthel index (SMD, 0.73; 95% CI, 0.53-0.94; P < .001) and the Fugl-Meyer assessment scores (SMD, 0.60; 95% CI, 0.34-0.86; P < .001). In the network analysis, MLC601, Shuxuetong, and BuchangNaoxintong were most likely to improve stroke recovery in patients without acupuncture. Additionally, Mailuoning, Xuesaitong, BuchangNaoxintong were the patented Chinese herbal medicines most likely to improve stroke recovery when combined with acupuncture.
CONCLUSIONS: Our research suggests that the Chinese herbal patent medicines were effective for stroke recovery. The most effective treatments for stroke recovery were MLC601, Shuxuetong, and BuchangNaoxintong. However, to clarify the specific effective ingredients of Chinese herbal medicines, a well-designed study is warranted.
