Evidence of anti-inflammatory effects of Passiflora edulis in an inflammation model

The popular medicine Passiflora edulis has been used as a sedative, tranquilizer, against cutaneous inflammatory diseases and intermittent fever. Most of the pharmacological investigations of Passiflora edulis have been addressed to its Central Nervous System activities, such as anxiolytic, anticonvulsant and sedative actions. Otherwise, there are few reports about the anti-inflammatory activity of the Passiflora species. The aim of this study was to investigate the mechanism of the anti-inflammatory effect of aqueous lyophilized extract obtained from leaves of Passiflora edulis var. flavicarpa Degener (Passifloraceae) in the mouse model of pleurisy induced by carrageenan (Cg), bradykinin, histamine or substance P, observing the effects upon leucocytes migration, myeloperoxidase (MPO), nitric oxide (NO) concentrations and tumor necrosis factor-alpha (TNFalpha) and interleukin-1 beta (IL-1beta) levels. RESULTS: Passiflora edulis (250mg/kg) administered by intraperitoneal route (i.p.) inhibited the leukocyte, neutrophils, myeloperoxidase, nitric oxide, TNFalpha and IL-1beta levels (P<0.01) in the pleurisy induced by carrageenan. Passiflora edulis (250-500mg/kg, i.p.) also inhibited total and differential leukocytes in the pleurisy induced by bradykinin, histamine or substance P (P<0.05). CONCLUSION: Several mechanisms, including the inhibition of pro-inflammatory cytokines (TNFalpha, IL-1beta), enzyme (myeloperoxidase) and mediators (bradykinin, histamine, substance P, nitric oxide) release and/or action, appear to account for Passiflora edulis's actions.

针刺中脘治疗消化性溃疡：多中心随机对照研究

目的:验证针刺中脘穴治疗消化性溃疡的有效性及安全性。方法:入选病例276例,随机分为针刺组与对照组。针刺组138例,选用中脘穴,长针深刺;对照组138例,口服泰胃美,共观察6周,通过临床症状及胃镜疗效两方面进行疗效观察。结果:针刺组对于快速改善胃脘疼痛及食少的症状效果明显优于对照组(P<0·05)。针刺组总有效率为90·6%,对照组总有效率为88·4%,针刺组疗效略优于对照组,但考虑中心效应,组间疗效无差异(P>0·05)。随着时间推移,两组症状均改善明显(P<0·01),但组间疗效无差异(P>0·05);两组胃镜疗效比较无差异(P>0·05)。结论:针刺中脘穴治疗消化性溃疡疗效可靠,值得临床推广应用。     

Contribution of Cardiorespiratory Fitness to the Obesity Paradox

Until recently, cardiorespiratory fitness (CRF) has been overlooked as a potential modifier of the inverse association between obesity and mortality (the so-called obesity paradox), observed in patients with known or suspected cardiovascular (CV) disease. Evidence from five observational cohort studies of 30,104 patients (87% male) with CV disease indicates that CRF significantly alters the obesity paradox. There is general agreement across studies that the obesity paradox persists among patients with low CRF, regardless of whether adiposity is assessed by body mass index, waist circumference, or percentage body fat. However, among patients with high CRF, risk of all-cause mortality is lowest for the overweight category in some, but not all, studies, suggesting that higher levels of fitness may modify the relationship between body fatness and survival in patients manifesting an obesity paradox. Further study is needed to better characterize the joint contribution of CRF and obesity on mortality in diverse populations.     

Insulin sensitivity (Si) assessment in lean and overweight subjects using two different protocols and updated software

Abstract

Background. The standard frequently-sampled intravenous glucose tolerance test (FSIVGTT) is an alternative procedure to the clamp technique for estimating the insulin sensitivity (Si) parameter. The goal of this study was to compare Si in lean and overweight individuals in addition to assessing intra-individual reproducibility using two different protocols and updated software. Methods. FSIVGTT was carried out in 14 lean (BMI ≤ 25 kg/m²) and 14 overweight (BMI>25 kg/m²) subjects using two different protocols; full (29 samples) and short (12 samples). For reproducibility assessment four normal subjects (triplicate on three and twice on one) were recruited to undergo the same procedure at 1-week intervals. Data analysis was performed using COMAL and Minmod Millennium software. Results. Mean Si (10^?4min^?1[pmol/l]^?1) values were significantly different between lean and overweight subjects (p < 0.001) but not between the two protocols using both software packages. For the full and short protocols, Si values were more closely related in lean versus overweight subjects using either COMAL (r = 0.98, p < 0.001), (r = 0.89, p < 0.001) or Minmod Millennium (r = 0.99, p < 0.001), (r = 0.85, p < 0.001) software respectively. The intra-individual reproducibility (%CV) of Si (COMAL) in full versus short protocol was 18.3 ± 11.1% and 13.7 ± 1.9% respectively. Reproducibility values for Si (Minmod Millenium) in full versus short protocols were 14.3 ± 3.8 and 14.9 ± 1.9% respectively. Conclusions. Si can be assessed accurately by a short protocol FSIVGTT in normal individuals. The short protocol may give less acceptable results for insulin sensitivity in individuals who have normal glucose tolerance but high BMI.
