The Role of Ophiopogonin D in Atherosclerosis: Impact on Lipid Metabolism and Gut Microbiota.

Gut microbiota has been proven to play an important role in many metabolic diseases and cardiovascular disease, particularly atherosclerosis. Ophiopogonin D (OPD), one of the effective compounds in Ophiopogon japonicus, is considered beneficial to metabolic syndrome and cardiovascular diseases. In this study, we have illuminated the effect of OPD in ApoE knockout (ApoE[Formula: see text] mice on the development of atherosclerosis and gut microbiota. To investigate the potential ability of OPD to alleviate atherosclerosis, 24 eight-week-old male ApoE[Formula: see text] mice (C57BL/6 background) were fed a high-fat diet (HFD) for 12 weeks, and 8 male C57BL/6 mice were fed a normal diet, serving as the control group. ApoE[Formula: see text] mice were randomly divided into the model group, OPD group, and simvastatin group ([Formula: see text]= 8). After treatment for 12 consecutive weeks, the results showed that OPD treatment significantly decreased the plaque formation and levels of serum lipid compared with those in the model group. In addition, OPD improved oral glucose tolerance and insulin resistance as well as reducing hepatocyte steatosis. Further analysis revealed that OPD might attenuate atherosclerosis through inhibiting mTOR phosphorylation and the consequent lipid metabolism signaling pathways mediated by SREBP1 and SCD1 in vivo and in vitro. Furthermore, OPD treatment led to significant structural changes in gut microbiota and fecal metabolites in HFD-fed mice and reduced the relative abundance of Erysipelotrichaceae genera associated with cholesterol metabolism. Collectively, these findings illustrate that OPD could significantly protect against atherosclerosis, which might be associated with the moderation of lipid metabolism and alterations in gut microbiota composition and fecal metabolites.

Modulatory effect of International Standard Scalp Acupuncture on brain activation in the elderly as revealed by resting-state fMRI.

The specific mechanisms by which acupuncture affects the central nervous system are unclear. In the International Standard Scalp Acupuncture system, acupuncture needles are applied at the middle line of the vertex, anterior parietal-temporal oblique line, and the posterior parietal-temporal oblique line. We conducted a single-arm prospective clinical trial in which seven healthy elderly volunteers (three men and four women; 50-70 years old) received International Standard Scalp Acupuncture at MS5 (the mid-sagittal line between Baihui (DU20) and Qianding (DU21)), the left MS6 (line joining Sishencong (EX-HN1) and Xuanli (GB6)), and the left MS7 (line joining DU20 and Qubin (GB7)). After acupuncture, resting-state functional magnetic resonance imaging demonstrated changes in the fractional amplitude of low frequency fluctuations and regional homogeneity in various areas, showing remarkable enhancement of regional homogeneity in the bilateral anterior cingulate, left medial frontal gyrus, supramarginal gyrus, right middle frontal gyrus, and inferior frontal gyrus. Functional connectivity based on a seed region at the right middle frontal gyrus (42, 51, 9) decreased at the bilateral medial superior frontal gyrus. Our data preliminarily indicates that the international standard scalp acupuncture in healthy elderly participants specifcally enhances the correlation between the brain regions involved in cognition and implementation of the brain network regulation system and the surrounding adjacent brain regions. The study was approved by the Ethics Committee of the China-Japan Union Hospital at Jilin University, China, on July 18, 2016 (approval No. 2016ks043).

Long-term acupuncture treatment has a multi-targeting regulation on multiple brain regions in rats with Alzheimer's disease: a positron emission tomography study.

The acute effect of acupuncture on Alzheimer's disease, i.e., on brain activation during treatment, has been reported. However, the effect of long-term acupuncture on brain activation in Alzheimer's disease is unclear. Therefore, in this study, we performed long-term needling at Zusanli (ST36) or a sham point (1.5 mm lateral to ST36) in a rat Alzheimer's disease model, for 30 minutes, once per day, for 30 days. The rats underwent 18F-fluorodeoxyglucose positron emission tomography scanning. Positron emission tomography images were processed with SPM2. The brain areas activated after needling at ST36 included the left hippocampus, the left orbital cortex, the left infralimbic cortex, the left olfactory cortex, the left cerebellum and the left pons. In the sham-point group, the activated regions were similar to those in the ST36 group. However, the ST36 group showed greater activation in the cerebellum and pons than the sham-point group. These findings suggest that long-term acupuncture treatment has targeted regulatory effects on multiple brain regions in rats with Alzheimer's disease.

Rapid Onset of the Effects of Combined Selective Serotonin Reuptake Inhibitors and Electroacupuncture on Primary Depression: A Meta-Analysis.

OBJECTIVES: To evaluate the efficacy and safety of combined selective serotonin reuptake inhibitors (SSRIs) and electroacupuncture therapies for the early treatment of primary depression. METHODS: Randomized controlled trials (RCTs) were analyzed to compare therapy combining SSRIs and electroacupuncture to SSRI therapy alone. The RCTs were identified by searching, among others, PubMed, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Chongqing VIP database for Chinese Technical Periodicals, WANFANG DATA, and the Chinese Biological Medical Literature Database. Scores from Self-Rated Depression Scale (SDS), the Hamilton Depression Scale (HAMD), the Side Effect Rating Scale (SERS), and the Treatment Emergent Symptom Scale (TESS) were analyzed and coded by two independent investigators and used to evaluate the safety and efficacy of treatment. Statistical analyses were performed using RevMan 5.2 software. RESULTS: Six RCTs were analyzed. The meta-analysis revealed that the combined therapy of SSRIs and electroacupuncture were associated with superior scores on the HAMD, SDS, and SERS measures compared with SSRIs alone after 1-4 weeks of treatment: HAMD scores, mean difference (MD)(1 week), 2.32 (95% confidence interval [CI](1 week), 1.47-3.16, p(1 week)<0.00001); MD(2 weeks), 2.65 (95% CI(2 weeks), 1.81- 3.50, p(2 weeks)<0.00001); MD(4 weeks), 2.70 (95% CI(4 weeks), 1.90-3.51, p(4 weeks)<0.00001); SDS scores: MD(1 week), 3.13 (95% CI(1 week), 1.22-5.03, p(1 week) = 0.001); MD(2 weeks), 4.05 (95% CI(2 weeks), 0.22-7.87, p(2 weeks) = 0.04); MD(4 weeks), 5.02 (95% CI(4 weeks), 1.61-8.43, p(4 weeks) = 0.004); SERS scores: MD(2 weeks), 2.20 (95% CI(2 weeks), 1.43-2.96, p(2 weeks)<0.00001); MD(4 weeks), 2.12 (95% CI(4 weeks), 1.42-2.83, p(4 weeks)<0.00001). However, two of the aforementioned outcomes were rated as medium quality because of heterogeneity, as assessed using the Grading of Recommendations Assessment, Development and Evaluation system. CONCLUSIONS: The available evidence suggests that the early treatment of primary depression using both SSRI and electroacupuncture therapies is more efficient than treatments with SSRIs alone and leads to a better and earlier control of depressive symptoms.

Lateralisation of cerebral response to active acupuncture in patients with unilateral ischaemic stroke: an fMRI study.

OBJECTIVE: Acupuncture is beneficial in treating stroke neuropsychiatric symptoms. The present study aimed to identify functional brain response to active acupuncture in patients with unilateral ischaemic stroke using functional MRI (fMRI). METHODS: A total of 10 patients aged 47-65 years with left hemispheric ischaemic stroke received single-session manual acupuncture at the TE5 point of the affected (right) forearm. A 6-min tactile control procedure in which an acupuncture needle tip was alternately touched and removed from the skin at the acupuncture point for 30 s each was performed first, followed by active acupuncture in a blocking paradigm consisting of six 30-s twist blocks of rotation interspersed between six 30-s blocks of rest. A whole brain scan was simultaneously conducted on a 3.0-T imager. Activated and deactivated brain regions during tactile stimulation and active acupuncture relative to rest were obtained via group analysis. RESULTS: Compared to tactile stimulation, needling with twist manipulation modulated many more widespread brain areas. All the brain areas activated and deactivated by active acupuncture relative to tactile stimulation were distributed in the primary sensorimotor and medial frontal cortex of the unaffected, but not the affected hemisphere. CONCLUSIONS: Active acupuncture results in lateralisation of functional cerebral response to the contralateral unaffected hemisphere in patients with unilateral stroke. This lateralisation may represent an effect of acupuncture in enhancing a compensatory process by redistributing functions into the intact cortex, particularly in the unaffected hemisphere.

[Effects of pomegranate flowers polyphenols on liver PON expression of diabetes combining non-alcoholic fat liver diseases rats].

To investigate the protective effects and possible mechanism of pomegranate flowers polyphenols (PFP) on liver function of rats with diabetes combining non-alcoholic fat liver diseases, diabetes combining nonalcoholic fat liver disease model rats were established with high calorie feeding and small dose intraperitoneal injection of streptozotocin (STZ). Model rats were randomly divided into: model group, metformin group, pomegranate flowers polyphenols low, medium and high dose group (75, 150 and 300 mg x kg(-1)). After four weeks treatment, the levels of FPG, blood fat profiles and serum insulin, ALT, AST levels, SOD and MDA in the liver and serum separately were analyzed with biochemical methods. Paraoxonase (PON1 and PON3) mRNA and protein expression in liver were checked by RT-PCR and immunohistochemical method. Pathological changes of the liver were observed. FPG, IRI, non-HDL-C and transaminase significantly reduced and HDL-C raised in the each PFP dose group; Furthermore, compared with model group, fat drops in liver cells significantly reduced, antioxidant ability enhanced, PON1 mRNA and protein expression level in liver increased significantly. The protective effects of PFP against diabetes combining non-alcoholic fat liver diseases rats might through the increase liver PON1 mRNA and protein expression further enhanced the body antioxidant capacity and reduced IRI so as to ameliorate the rat hepatic steatosis.

A 6-week randomized controlled trial with 4-week follow-up of acupuncture combined with paroxetine in patients with major depressive disorder.

Acupuncture possesses the antidepressant potential. In this 6-week randomized controlled trial with 4-week follow-up, 160 patients with major depressive disorder (MDD) were randomly assigned to paroxetine (PRX) alone (n = 48) or combined with 18 sessions of manual acupuncture (MA, n = 54) or electrical acupuncture (EA, n = 58). Treatment outcomes were measured mainly using the 17-item Hamilton Depression Rating Scale (HAMD-17), Self-rating Depression Scale (SDS), clinical response and remission rates. Average PRX dose taken and proportion of patients who required an increased PRX dose due to symptom aggravation were also obtained. Both additional MA and EA produced a significantly greater reduction from baseline in score on HAMD-17 and SDS at most measure points from week 1 through week 6 compared to PRX alone. The clinical response was markedly greater in MA (69.8%) and EA (69.6%) groups than the group treated with PRX alone (41.7%, P = 0.004). The proportion of patients who required an increase dose of PRX due to symptom aggravation was significantly lower with MA (5.7%) and EA (8.9%) than PRX alone (22.9%, P = 0.019). At 4 weeks follow-up after completion of acupuncture treatment, patients with EA, but not MA, continued to show significantly greater clinical improvement. Incidence of adverse events was not different in the three groups. Our study indicates that acupuncture can accelerate the clinical response to selective serotonin reuptake inhibitors (SSRIs) and prevent the aggravation of depression. Electrical acupuncture may have a long-lasting enhancement of the antidepressant effects (Trial Registration: ChiCTR-TRC-08000278).
