Decreased Risk of Pneumonia in Stroke Patients Receiving Acupuncture

Chang CC1,2,3, et al.

BACKGROUND: Acupuncture treatment is common among stroke patients, but there is limited information available on whether acupuncture effectively prevents post-stroke pneumonia. The aim of this study was to analyze the differential risk of pneumonia after stroke between patients who did and did not receive acupuncture after discharge.
METHODS: We used the Taiwan National Health Insurance Research Database to conduct a retrospective cohort study using propensity score matched-pairs of new stroke patients in 2000-2004 who did and did not receive acupuncture post-stroke. Both cohorts were followed up until the end of 2009 for new-onset pneumonia. After correcting for immortal time bias, the incidence and adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) of pneumonia associated with acupuncture use were calculated using multivariate Cox proportional hazard models.
RESULTS: Overall, 12557 stroke patients with 12557 paired controls were included in the analysis; pneumonia was diagnosed in 6796 (27.1%). Stroke patients receiving acupuncture had a lower incidence of pneumonia than those without acupuncture (53.4 vs. 58.9 per 1000 person-years), with an adjusted HR of 0.86 (95% CI 0.82-0.90). The association between pneumonia risk and acupuncture use was significant in men (HR 0.92, 95% CI 0.86-0.98) and women (HR 0.79, 95% 0.70-0.82) and was also observed in every age group from 20-79 years.
CONCLUSION: Stroke patients receiving acupuncture had a lower risk of pneumonia than those who did not. Further randomized control studies are needed to validate the protective effect of acupuncture on the risk of pneumonia among stroke patients.

Modulation of Functional Activity and Connectivity by Acupuncture in Patients with Alzheimer Disease as Measured by Resting-State fMRI

Zheng W1, et al.

Acupuncture has been used in the therapy of Alzheimer disease (AD); however, its neural mechanisms are still unclear. The aim of this study is to examine the effect of acupuncture on the functional connectivity in AD by using resting-state functional magnetic resonance imaging (rs-fMRI). Twenty-eight subjects (14 AD and 14 normal controls) participated in this study. The rs-fMRI data were acquired before and after acupuncture stimulation at the acupoints of Tai chong (Liv3) and Hegu (LI4). During the baseline resting state, by using the amplitude of low-frequency fluctuations (ALFF), we found a significantly decreased or increased ALFF in the AD patients relative to the controls. These regions were located in the right superior frontal gyrus (SFG), left postcentral gyrus, subgenual cingulate cortex (SCC), right middle cingulate cortex (MCC), right inferior frontal gyrus (IFG), right hippocampus and the right inferior temporal gyrus (ITG). Then, we selected these brain regions as seeds to investigate whether regional activity and functional connectivity could be modulated by acupuncture in the AD patients. When compared to the pre-acupuncture stage, several of the above regions showed an increased or decreased ALFF after acupuncture in the AD patients. In addition, the functional connectivity between the hippocampus and the precentral gyrus showed enhancement after acupuncture in the AD patients. Finally, there were close correlations between the functional activity, connectivity and clinical performance in the AD patients. The current study confirmed that acupuncture at Tai chong (Liv3) and He gu (LI4) can modulate functional activity and connectivity of specific cognition-related regions in AD patients.

Yangyin Fuzheng Decoction Enhances Anti-Tumor Efficacy of Cisplatin on Lung Cancer

Wei D1, et al.

Traditional Chinese medicine has been widely used in cancer treatment in China. Yangyin Fuzheng Decoction is a traditional Chinese compound medicine, composed of 12 traditional Chinese herbs. This study aimed to investigate anti-tumor activity and the underlying mechanisms of Yangyin Fuzheng Decoction combined with cisplatin in the treatment of lung cancer. We established lung cancer model in C57BL/6 mice injected with mouse Lewis lung cancer cells. Our results demonstrated that Yangyin Fuzheng Decoction treatment increased necrotic area in tumor tissue, and significantly enhanced the recruitment of inflammatory cells into the tumor. In addition, Yangyin Fuzheng Decoction treatment enhanced the anti-tumor efficacy of cisplatin and partially recovered mouse body weight loss caused by cisplatin treatment. Mechanistically, we found that Yangyin Fuzheng Decoction upregulated the expression of pro-apoptotic proteins p53 and Bax and suppressed the expression of anti-apoptotic protein Bcl-2. Combined treatment of Yangyin Fuzheng Decoction and cisplatin further increased p53 and Bax levels and suppressed Bcl-2 level. Taken together, these data suggest that Yangyin Fuzheng Decoction could synergistically enhance the apoptotic signaling in cancer cells during chemotherapy. In addition, it has health improving and immune response enhancing effects. Yangyin Fuzheng Decoction could be a promising adjunct agent for lung cancer chemotherapy.
