Meta Analysis
A systematic review of integrated traditional Chinese and Western medicine for managing irritable bowel syndrome.
Traditional Chinese medicine (TCM) has been commonly used by Chinese practitioners to treat irritable bowel syndrome (IBS). However, the effectiveness of combining TCM with Western medicine in managing IBS has not been evaluated systematically. In this study, we evaluated the clinical effectiveness of combining TCM and Western medicine in the treatment of IBS via meta-analyses. ⋯ These results demonstrated that treating IBS with integrated traditional Chinese and Western medicines showed better effectiveness than conventional Western medicine alone. Although due to the quality of the included studies, our results might possess a high risk of bias. TCM, particularly Chinese proprietary medicine, with the benefits of low-cost, easy to use, and good palatability, would be an attractive option to be used in conjunction with conventional Western medicine to manage IBS patients.

Reductions in neurotrophic factors are implicated in synaptic dysfunction in the central nervous system, but exogenous neurotrophic factors with potential effects on neuritic regeneration and synaptic reconstruction could offer therapeutic and preventive strategies for treating memory-related neurological disorders. In an earlier effort to identify natural neurotrophic agents, we found that the ethanol extract of the edible marine alga Undaria pinnatifida (UPE) had promising effects on the neuritogenesis of cultured hippocampal neurons. ⋯ It was found that UPE triggered significant increase in numbers of dendritic filopodia and spines, promoted the formation of excitatory and inhibitory synapses, and potentiated synaptic transmission by increasing the sizes of reserve vesicle pools at presynaptic terminals. These findings indicate a substantial role for UPE in the morphological and functional maturation of neurons and suggest that UPE is a possible therapeutic preventative measure and treatment for neurodegenerative diseases, such as those involving cognitive disorders and memory impairments.

Spiranthes sinensis is an east Asian wild orchid used in Chinese folk medicine. In this study, an ethyl acetate fraction from S. sinensis(SSE) was found to suppress the production of LPS-stimulated inflammatory mediators in RAW264.7 cells and BALB/c mice. SSE inhibited the production of pro-inflammatory mediators such as nitric oxide (NO), prostaglandin E2 (PGE2), tumo necrosis factor-α (TNF-α), IL-1β, and IL-6 in LPS-stimulated RAW264.7 cells. ⋯ In vivo, we demonstrated that SSE attenuated the levels of pro-inflammatory mediators (NO, TNF-α, IL-1β, and IL-6), ALT, and AST in the serum of LPS-stimulated BALB/c mice. Western blotting revealed that SSE enhanced HO-1 expression in lung and liver tissue after LPS injection in mice. These results suggest that the anti-inflammatory properties of SSE involve the suppression of iNOS, mPGES-1, and inflammatory mediators by inducing the HO-1 pathway in LPS-stimulated RAW264.7 cells and BALB/c mice.

Review Meta Analysis
The Effects of Qigong for Adults with Chronic Pain: Systematic Review and Meta-Analysis.
A systematic review was conducted to evaluate the effectiveness of qigong as a treatment for chronic pain. Five electronic databases were searched from their date of establishment until July 2014. The review included 10 randomized clinical trials (RCTs) that compared the impacts of qigong on chronic pain with waiting list or placebo or general care. ⋯ This study showed that internal qigong generated benefits on treating some chronic pain with significant differences. External qigong showed nonsignificant differences in treating chronic pain. Higher quality randomized clinical trials with scientific rigor are needed to establish the effectiveness of qigong in reducing chronic pain.

Butein is a polyphenol, one of the compounds of chalcones, which are flavonoids that are widely biosynthesized in plants, and exhibits different pharmacological activities. Plants containing butein have been used in Chinese traditional medicine. Recently, it has been reported that butein suppresses proliferation and triggers apoptosis in various human cancer cells in vitro and in vivo. ⋯ In addition, butein also down-regulated the expressions of the inhibitor of apoptosis (IAP) proteins, XIAP, survivin, CIAP-1, and CIAP-2. This indicates that the inhibition of IAP proteins was also involved in butein-induced apoptosis. The results of our study suggest that butein may be a promising anticancer agent in treating ovarian cancer.
