Acupuncture ameliorates negative emotion in PCOS patients: a randomized controlled trial / 中国针灸

OBJECTIVE@#To evaluate the effectiveness and possible mechanism of acupuncture treatment for negative emotion in patients with polycystic ovary syndrome (PCOS).@*METHODS@#A total of 40 PCOS patients were randomly divided into an observation group and a control group, 20 cases in each one. Both groups received lifestyle interventions (exercise and diet guidance) on the 5th day of menstruation. On the basis of above treatment, the patients in the observation group received acupuncture at Guanyuan (CV 4), Zhongwan (CV 12), Guilai (ST 29), Futu (ST 32), Liangqiu (ST 34), Sanyinjiao (SP 6), Zusanli (ST 36), Hegu (LI 4), Shenmen (HT 7), Baihui (GV 20) as the main acupoints, and connected the electroacupuncture (continuous wave, 2 Hz, 30 min), once every other day, 3 times a week. The treatment for 1 month was as one course and 4 courses were required totally in both groups. Before and after treatment, the body mass index (BMI), ferriman-gallway (F-G) score, self-rating anxiety scale (SAS) score, self-rating depression scale (SDS) score, PCOS health-related quality of life questionnaire (PCOSQ) score were observed, meanwhile, serum sex hormone, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E), progestin (P), prolactin (PRL), testosterone (T), sex hormone-binding globulin (SHBG) and free androgen index (FAI) levels, and serumβ-endorphin levels were detected.@*RESULTS@#Compared with before treatment, the BMI, F-G score, SAS score, SDS score and serum FAI level were decreased and the PCOSQ score and the levels of serum SHBG andβ-endorphin were increased in the observation group after treatment (all <0.05). Compared with before treatment, the SDS score was decreased in the control group after treatment (<0.05). Compared with the control group, the F-G score, SDS score, SAS score, and serum FAI level were lower, and the PCOSQ score and serumβ-endorphin level were higher in the observation group after treatment (all <0.05).@*CONCLUSION@#Applying acupuncture to the treatment of patients with PCOS can effectively relieve anxiety and depression, and the mechanism may be related to the regulation on the levels of serumβ-endorphin and androgen.

Protective Effect of Norcantharidin on Collagen-Induced Arthritis Rats / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effect of norcantharidin (NCTD) on collagen-induced arthritis (CIA) rats.</p><p><b>METHODS</b>Sixty Sprague-Dawley(SD) rats were randomly divided into 6 groups (n=10): normal group, CIA model group(model group), NCTD low-dose group [1.35 mg/(kg•d)], NCTD middle-dose group [2.7 mg/(kg•d)], NCTD high-dose group [5.4 mg/(kg•d)] and methotrexate (MTX) group [1.8 mg/(kg/w)]. Anesthetized rats were sacrificed by luxation of cervical vertebra after 4 weeks of administration. The arthritis scores were evaluated twice a week. The pathological changes in the ankle joints of rats were observed by hematoxylin-eosin (H&E) staining. The serum levels of interleukin (IL) 1β, IL-6, tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), IL-17 and transform growth factor (TGF) β were detected by enzyme linked immunosorbent assay (ELISA). The mRNA expression of retinoid-related orphan nuclear receptorγt (RORγt) and forkhead box P3 (Foxp3) in peripheral blood lymphocytes were confirmed by real-time polymerase chain reaction.</p><p><b>RESULTS</b>MTX and high-dose NCTD not only decreased the arthritis scores but also alleviated the pathological changes in CIA rats' ankle joints compared with the model group (P<0.05 or P<0.01). All doses of NCTD significantly inhibited the serum levels of IL-6, IL-17 and TNF-α in CIA rats (P<0.05). Only middle- and high-dose of NCTD prominently decreased serum IL-1β and TGF-β levels of CIA rats (P<0.05). However, NCTD has no effect on vascular endothelial growth factor (VEGF) level in CIA rats. The Foxp3 mRNA expression in all NCTD groups were increased significantly than in the model group (P<0.05). The mRNA expression of RORγt in NCTD high-dose group was decreased apparently in comparison with the model group (P<0.05).</p><p><b>CONCLUSIONS</b>NCTD showed therapeutic effect on CIA rats by inhibition of cytokines and regulation of Th17/Treg cells.</p>

Effect of electroacupuncture stimulation on expression of angiotensinogen, angiotensin II type 1 receptor, endothelin-1, and endothelin a receptor mRNA in spontaneously hypertensive rat aorta / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effect of electroacupuncture (EA) stimulation on the expressions of angiotensinogen (AGT), angiotensin II type 1 receptor (AT1R), endothelin-1 (ET1), and endothelin A receptor (ETAR) mRNA in spontaneously hypertensive rat (SHR) aorta.</p><p><b>METHODS</b>Eighteen male SHRs were randomly divided into three groups, an SHR group, an SHR Baihui (DU 20) and Zusanli (ST 36) acupoint (SHR-AP) group, and an SHR non-acupoint (SHR-NAP) group, with 6 rats in each group. Six Wistar rats were used as a control. Rats in the SHR-AP group were stimulated by DU 20 and ST 36 acupoints, both of which were connected with EA. EA was handled one time every Monday, Wednesday and Friday, for total 24 times (8 weeks). SHRNAP rats were acupointed at a 15°angle flat into 0.5 cm to two points, which were 1 and 2 cm from rail tip separately. EA parameters were the same as the SHR-AP rats. SHR control rats and Wistar rats were fixed without EA. Real-time quantitative polymerase chain reaction (PCR) was used to measure AGT, AT1R, ET1, and ETAR mRNA expression in rat aorta.</p><p><b>RESULTS</b>EA stimulation significantly reduced rat aorta vascular AGT, ET1, ETAR and AT1R mRNA expressions in the SHR-AP and SHR-NAP groups (P <0.01). Among these four genes, AT1R mRNA expression was significantly lower in the SHR-AP than in the SHR-NAP group (P <0.01).</p><p><b>CONCLUSION</b>EA could reduce the AT1R mRNA expression in SHR-AP rat aorta, indicating a potential mechanism for the hypotensive effects of EA.</p>
