Osteoarthritis is a highly prevalent progressive joint disease that still requires an optimal therapeutic approach. Intermittent fasting is an attractive dieting strategy for improving health. Here this study shows that intermittent fasting potently relieves medial meniscus (DMM)‐ or natural aging‐induced osteoarthritic phenotypes. Osteocytes, the most abundant bone cells, secrete excess neuropeptide Y (NPY) during osteoarthritis, and this alteration can be altered by intermittent fasting. Both NPY and the NPY‐abundant culture medium of osteocytes (OCY‐CM) from osteoarthritic mice possess pro‐inflammatory, pro‐osteoclastic, and pro‐neurite outgrowth effects, while OCY‐CM from the intermittent fasting‐treated osteoarthritic mice fails to induce significant stimulatory effects on inflammation, osteoclast formation, and neurite outgrowth. Depletion of osteocyte NPY significantly attenuates DMM‐induced osteoarthritis and abolishes the benefits of intermittent fasting on osteoarthritis. This study suggests that osteocyte NPY is a key contributing factor in the pathogenesis of osteoarthritis and intermittent fasting represents a promising nonpharmacological antiosteoarthritis method by targeting osteocyte NPY.

Background: To provide evidence that the Chinese herbal medicine (CHM) PSORI-CM01 combined with Western medicine reduces the relapse rate of psoriasis vulgaris (PV), we plan to conduct a large-scale randomized control trial (RCT). In order to improve and perfect the RCT, this pilot study was designed to determine the feasibility and the potential of a modified protocol for the full-scale RCT.Methods: Eligible patients with psoriasis vulgaris (PV) were enrolled into a randomized comparison in which all subjects received topical sequential therapy and PSORI-CM01 or placebo for 12 weeks. The primary outcome measure was the relapse rate. Treatment response was computed from Psoriasis Area and Severity Index (PASI), body surface area (BSA), and Dermatology Life Quality Index (DLQI). The secondary outcome measures included time to relapse, time to onset, rebound rate, PASI score, pruritus scores on the Visual Analog Scale (VAS), BSA, DLQI and SF-36 (short form health survey), and incidence of serious adverse events (SAEs).Results: Six of 7 (86 %) subjects reached the PASI-50 in the CHM group compared with nine of 10 (90 %) in the placebo group during the treatment period. Among the subjects who reached PASI-50, one out of six subjects (17 %) relapsed in the CHM group during the treatment period compared with six out of nine patients in the placebo group (67 %). No subjects met the rebound criteria. Changes to baseline in the PASI scores were not significantly different between the two groups (t = 1.764, P = 0.098).Conclusion: Oral PSORI-CM01 combined with topical sequential treatment showed a smaller recurrence rate (P = 0.118) than placebo combined with the same topical therapy for moderate-to-severe PV in this pilot study.Trial Registration: Chinese Clinical Trial Registry ( http://www.chictr.org.cn/searchproj.aspx ) ChiCTR-TRC-13003233 ; date of registration: 15 April 2013.

Objective: To develop quality of life questionnaire of Chinese medicine for postoperative patients with colorectal cancer (QLQ-CMPPCC), thus comprehensively and objectively evaluating the clinical efficacy of Chinese medicine and pharmacy in treating postoperative patients with colorectal cancer (CC)., Methods: The theoretical structure model of the questionnaire was addressed in combined with basic theories of Chinese medicine according to the principle of WHO quality of life (QOL). The primary questionnaire was developed using methods of structuralization policy making after we extensively retrieve various universal and specific questionnaires for CC cancer patients at home and abroad. The 205 CC patients were tested by questionnaire. The items were screened using experts grading method, item selection analysis, dispersion trends of standard deviation, t-test, correlation coefficient method, factor analysis,and Cronbach's alpha., Results: The QLQ-CMPPCC was developed containing four domains of physical, psychological, independence, and social functions, involving 20 aspects and 54 items. Of them, non-fistula patients answered 43 items and fistula patients answered 46 items. One item covered the general QOL evaluation., Conclusions: QLQ-CMPPCC showed Chinese medical features. It comprehensively reflected the connotation of QOL for postoperative CC patients. It could be taken as a tool for evaluating Chinese medical efficacy for postoperative CC patients.

Objective: Based on the 2002 WHO health survey data, to explore the latent relationship among self-reported health level, the actual level of health, the social demographic characteristics and the risk factors, and to analyze the influence of the various surveillance indicators on self-reported health and the degree that the self-reported health explained the actual level of health., Methods: Field tests for various components of the World health survey were conducted in nine countries during 2002, including India, Brazil, Burkina, Hungary, Nepal, Russia, Spain, Tunisia, and Vietnam (29 971). The survey questionnaire included a self-assessment component and anchoring vignette component. The self-assessment component data was adjusted and eliminated the affect of "cut-point bias" by using the anchoring vignette component data, and then was used to build the structural equation model on the relationship among self-reported health level, actual health level, social demographic characteristics and the risk factors., Results: In the final structural equation model, "the actual level of health" = 0.80 × "the self-reported health level" + (-0.04) × "the social demographic characteristics" + (-0.08) × "the risk factors" (R(2) = 0.66), and "the self-reported health level" = (-0.70) × "the social demographic characteristics" + 0.10 × "the risk factors" (R(2) = 0.55). The standardized total effect of self-reported health to the actual level of health was 0.80, and that of the social demographic characteristics to the self-reported health and the actual level of health were -0.70 and -0.60, respectively. And the 16 items of self-reported health consisted of 8 dimensions; and sorted by the power of impact to the actual health level, they were mobility, pain and discomfort, sleep, cognition, feelings, self-care ability, visual capacity and interpersonal activities., Conclusion: There were significant linear correlation relationship between the actual level of health and the self-reported health, as well as between the self-reported health and the social demographic characteristics. And the self-reported 16 items used by the 2002 WHO health survey played an important role in the health evaluation of population.
