ABSTRACT
OBJECTIVE@#To observe the effect of ginger-separated moxibustion on fatigue, sleep quality and depression in the patients with chronic fatigue syndrome.@*METHODS@#A total of 62 patients with chronic fatigue syndrome were randomized into an observation group (31 cases, 3 cases dropped off) and a control group (31 cases, 2 cases dropped off). In the control group, the patients had normal diet and proper physical exercise. In the observation group, on the basis of the control group, the ginger-separated moxibustion was added at Zhongwan (CV 12), Shenque (CV 8) and Guanyuan (CV 4), 30 min each time, once every two days, 3 times weekly. Separately, before treatment and after 4 weeks of treatment, the MOS item short form health survey (SF-36), the Pittsburgh sleep quality index (PSQI) scale and the self-rating depression scale (SDS) were adopted to evaluate the degrees of fatigue, sleep quality and depression in the patients of the two groups.@*RESULTS@#In the observation group, the score of each item of SF-36, the score of each item of PSQI and SDS score after treatment were all improved significantly as compared with those before treatment respectively (<0.05, <0.01). In the control group, the scores of overall health, vitality and mental health in SF-36 and the score of sleep time of PSQI after treatment were improved as compared with those before treatment respectively (<0.05). After treatment, the score of each item of SF-36, the scores of sleep quality, sleep time, sleep efficiency and sleep disorders of PSQI, as well as SDS score in the observation group were all better than those in the control group respectively (<0.01, <0.05). The score of SF-36 was relevant to the scores of PSQI and SDS in the patients of chronic fatigue syndrome ( =0.331, <0.05; =-0.706, <0.01). The improvement value of SF-36 score was closely related to the improvement value of SDS score in the observation group ( =-0.657, <0.01).@*CONCLUSION@#The ginger-separated moxibustion effectively relieves fatigue and depression condition and improves sleep quality in the patients with chronic fatigue syndrome. The fatigue condition is relevant with sleep quality and depression condition to a certain extent in the patients.
ABSTRACT
Osteoclast-like cells are known to inhibit arterial calcification. Receptor activator of NF-κB ligand (RANKL) is likely to act as an inducer of osteoclast-like cell differentiation. However, several studies have shown that RANKL promotes arterial calcification rather than inhibiting arterial calcification. The present study was conducted in order to investigate and elucidate this paradox. Firstly, RANKL was added into the media, and the monocyte precursor cells were cultured. Morphological observation and Tartrate resistant acid phosphatase (TRAP) staining were used to assess whether RANKL could induce the monocyte precursor cells to differentiate into osteoclast-like cells. During arterial calcification, in vivo and in vitro expression of RANKL and its inhibitor, osteoprotegerin (OPG), was detected by real-time PCR. The extent of osteoclast-like cell differentiation was also assessed. It was found RANKL could induce osteoclast-like cell differentiation. There was no in vivo or in vitro expression of osteoclast-like cells in the early stage of calcification. At that time, the ratio of RANKL to OPG was very low. In the late stage of calcification, a small amount of osteoclast-like cell expression coincided with a relatively high ratio of RANKL to OPG. According to the results, the ratio of RANKL to OPG was very low during most of the arterial calcification period. This made it possible for OPG to completely inhibit RANKL-induced osteoclast-like cell differentiation. This likely explains why RANKL had the ability to induce osteoclast-like cell differentiation but acted as a promoter of calcification instead.
