Efficacy of Intensive Acupuncture Versus Sham Acupuncture in Knee Osteoarthritis

Jian-Feng Tu, et al.

Objective: To assess the efficacy of intensive acupuncture (3 times weekly for 8 weeks) versus sham acupuncture for knee osteoarthritis (OA).
Methods: In this multicenter, randomized, sham-controlled trial, patients with knee OA were randomly assigned to receive electroacupuncture (EA), manual acupuncture (MA), or sham acupuncture (SA) 3 times weekly for 8 weeks. Participants, outcome assessors, and statisticians were blinded with regard to treatment group assignment. The primary outcome measure was response rate, which is the proportion of participants who simultaneously achieved minimal clinically important improvement in pain and function by week 8. The primary analysis was conducted using a Z test for proportions in the modified intent-to-treat population, which included all randomized participants who had =1 post-baseline measurement.
Results: Of the 480 participants recruited in the trial, 442 were evaluated for efficacy. The response rates at week 8 were 60.3% (91 of 151), 58.6% (85 of 145), and 47.3% (69 of 146) in the EA, MA, and SA groups, respectively. The between-group differences were 13.0% (97.5% confidence interval [97.5% CI] 0.2%, 25.9%; P = 0.0234) for EA versus SA and 11.3% (97.5% CI -1.6%, 24.4%; P = 0.0507) for MA versus SA. The response rates in the EA and MA groups were both significantly higher than those in the SA group at weeks 16 and 26.
Conclusion: Among patients with knee OA, intensive EA resulted in less pain and better function at week 8, compared with SA, and these effects persisted though week 26. Intensive MA had no benefit for knee OA at week 8, although it showed benefits during follow-up.

Effects of Acupuncture on Cardiovascular Risks in Patients with Hypertension

Hyejin Jung, et al.

Objectives: The aim of this study was to investigate the effects of acupuncture on major adverse cardiovascular events (MACE), myocardial infarction, stroke and death in hypertensive patients taking anti-hypertensives.
Methods: Using the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC) database, this study identified 59,370 patients taking anti-hypertensives who had been diagnosed with hypertension between 2003 and 2006. They were divided into acupuncture and non-acupuncture groups. The follow-up period ended with the diagnosis of myocardial infarction, stroke or death. After propensity score matching (PSM), there were 18,011 patients each in the non-acupuncture and acupuncture groups. We calculated the incidence rate, hazard ratio (HR) and 95% confidence interval (CI) for MACE, myocardial infarction, stroke and death in patients with hypertension using a stratified Cox proportional hazard model. In addition, secondary outcome analyses for stroke and cardiovascular mortality were performed.
Results: After PSM, the HRs for MACE (0.83, 95% CI 0.80-0.86), all-cause mortality (0.73, 95% CI 0.70-0.76) and myocardial infarction (0.85, 95% CI 0.79-0.92) were significantly lower in the acupuncture group than in the non-acupuncture group. Moreover, the HRs for stroke-related mortality, hemorrhage stroke-related mortality, ischemic stroke-related mortality, ischemic heart disease-related mortality and circulatory system disease-related mortality were significantly lower in the acupuncture group than in the non-acupuncture group.
Conclusion: This observational study with long-term follow-up extends the evidence base in support of the effectiveness of acupuncture for the management of hypertension and potentially reduce the burden of cardiovascular disease.

Anti-inflammatory Property and Functional Substances of Lonicerae Japonicae Caulis

Xiaorong Su, et al.

Ethnopharmacological relevance: Lonicerae Japonicae Caulis, the dried stem and branch of Lonicera japonica Thunb., is a Chinese Materia Medica known as Ren Dong Teng in Chinese with long use history in the traditional Chinese medicine (TCM) prescriptions. Lonicerae Japonicae Caulis possesses heat-clearing and detoxifying functions according to the TCM theory. In recent years, a large amount of experimental and clinical studies proved good anti-inflammatory effects of some heat-clearing and detoxifying herbs. The present study aims to reveal the anti-inflammatory property and functional substances of Lonicerae Japonicae Caulis.
Materials and methods: For anti-inflammatory activity test, LPS-induced RAW 264.7 macrophages, DSS-induced SPF male C57BL/6J mice model, and LPS-induced SPF male ICR mice model were used in vitro and in vivo, respectively. The behavioral changes, organ damage, and the expression of inflammatory factors such as TNT-a and IL-6 mRNA expression were measured for activity evaluation. Lonicerae Japonicae Caulis samples were prepared by solvent extraction and subsequent column chromatography. The main components were identified and determined using UPLC-UV analysis as well as NMR interpretation after purification. To testify the contribution of main components for the anti-inflammatory activity, different samples were also prepared by compound-knockout strategy.
Results: Ethanol extract of Lonicerae Japonicae Caulis could attenuate sickness symptoms in mice such as diarrhea, less activity, and depression. It could also alleviate multiple organ damage, and significantly inhibit the expression of pro-inflammatory factors such as TNF-a, IL-1ß, IL-6 and IFN-? in mice. Furthermore, the isochlorogenic acid-rich and biflavonoid-rich fractions and isochlorogenic acids A and C, and ochnaflavone could significantly down-regulate the mRNA expression of TNF-a and IL-6 in LPS-induced RAW 264.7 macrophages.
Conclusions: Lonicerae Japonicae Caulis possesses anti-inflammatory property. Its isochlorogenic acid-rich and biflavonoid-rich fractions do the major contribution. And their main components, isochlorogenic acids A and C, and ochnaflavone, take main responsibility for the anti-inflammatory property.
