[Effect of regulating menstruation and promoting pregnancy acupuncture therapy on negative emotion in patients with premature ovarian insufficiency].

OBJECTIVE: To observe the influence of regulating menstruation and promoting pregnancy acupuncture therapy on negative emotions in patients with premature ovarian insufficiency (POI). METHODS: A total of 60 patients with POI were randomly divided into an acupuncture group and a western medication group, 30 cases in each group. The acupuncture group was treated with regulating menstruation and promoting pregnancy acupuncture therapy at Baihui (GV 20), Shenting (GV 24), Guanyuan (CV 4), Sanyinjiao (SP 6), Shenshu (BL 23), Ciliao (BL 32), etc. once a day, 5 times a week for 3 months. The western medication group was treated by oral administration of climen. The drug was given 1 tablet a day for 21 days and was stopped for 1 week as a course. The treatment was required 3 consecutive courses. The self-rating anxiety scale (SAS) score, modified Kupperman index (KI) score, agitated and depressive symptom scores in KI and serum level of follicle stimulating hormone (FSH) before and after treatment were compared between the two groups. RESULTS: After treatment, the SAS scores, KI scores and serum levels of FSH in the two groups and the scores of agitated and depressive symptom in the acupuncture group were lower than those before treatment (P<0.05), and the acupuncture group was lower than the western medication group (P<0.05). CONCLUSION: Regulating menstruation and promoting pregnancy acupuncture therapy can effectively improve the negative emotions of patients with POI and reduce serum level of FSH .

Biochanin A Mitigates Atherosclerosis by Inhibiting Lipid Accumulation and Inflammatory Response.

Biochanin A (BCA), a dietary isoflavone extracted from red clover and cabbage, has been shown to antagonize hypertension and myocardial ischemia/reperfusion injury. However, very little is known about its role in atherogenesis. The aim of this study was to observe the effects of BCA on atherosclerosis and explore the underlying mechanisms. Our results showed that administration of BCA promoted reverse cholesterol transport (RCT), improved plasma lipid profile, and decreased serum proinflammatory cytokine levels and atherosclerotic lesion area in apoE-/- mice fed a Western diet. In THP-1 macrophage-derived foam cells, treatment with BCA upregulated ATP-binding cassette (ABC) transporter A1 (ABCA1) and ABCG1 expression and facilitated subsequent cholesterol efflux and diminished intracellular cholesterol contents by activating the peroxisome proliferator-activated receptor γ (PPARγ)/liver X receptor α (LXRα) and PPARγ/heme oxygenase 1 (HO-1) pathways. BCA also activated these two signaling pathways to inhibit the secretion of proinflammatory cytokines. Taken together, these findings suggest that BCA is protective against atherosclerosis by inhibiting lipid accumulation and inflammatory response through the PPARγ/LXRα and PPARγ/HO-1 pathways. BCA may be an attractive drug for the prevention and treatment of atherosclerotic cardiovascular disease.

[Manual Acupuncture Stimulation Regulates Expression of Receptor Activity-modifying Protein 1 and 5-HT 1 D Receptor Proteins and Genes in Migraine Rats].

OBJECTIVE: To observe the effect of liver-soothing and mental-activity-regulating (LSMAR) needling on the expression of receptor activity-modifying protein 1 (RAMP 1, receptor of calcitonin gene-related peptide), 5-hydroxytryptamine 1 D receptor(5-HT 1 DR) in the spinal trigeminal nucleus (STN) and midbrain in migraine rats, so as to explore its underlying mechanism in relieving migraine. METHODS: A total of 40 male Wistar rats were randomly divided into control, model, LSMAR and conventional needling groups (n=10 rats in each). The migraine model was established by subcutaneous injection of nitroglycerin at the posterior neck. LSMAR was applied to "Baihui" (GV 20), bilateral "Fengchi" (GB 20), "Neiguan" (PC 6) and "Taichong" (LR 3) in the LSMAR group and conventional needling was applied to "Baihui" (GV 20) and bilateral "Fengchi" (GB 20) in the conventional acupuncture group for 30 min, once a day for 8 days before modeling. The expression levels of RAMP 1 and 5-HT 1 DR proteins and mRNAs in the STN and mesencephalon were detected by real-time fluorescent quantitative PCR and Western blot, separately. RESULTS: Compared with the control group, the expression levels of RAMP 1 protein and mRNA in STN and mesencephalon were significantly increased (P<0.05) and those of 5-HT 1 DR protein and mRNA considerably decreased (P<0.05) in the model group. After the acupuncture treatment, the increased levels of RAMP 1 protein and mRNA and the decreased levels of 5-HT 1 DR protein and mRNA in the STN and midbrain were obviously reversed in the LSMAR and conventional needling groups relevant to the model group (P<0.05). The effect of LSMAR needling was significantly superior to that of conventional needling in down-regulating the expression levels of RAMP 1 mRNA and protein in the STN and mesencephalon (P<0.05) and in up-regulating the expression levels of 5-HT 1 DR mRNA and protein in the two brain regions (P<0.05). CONCLUSION: Manual acupuncture stimulation of GV 20, GB 20, etc. can inhibit the expression of RAMP 1 protein and mRNA in the STN and midbrain, and up-regulate the expression of 5-HT 1 DR in the two brain regions of migraine rats, which may be related to its effect in relieving migraine.

[Effect of Manual Acupuncture Preconditioning on Behavior and Contents of Serum CGRP, SP, IL-1 ß and TNF-α Levels in Migraine Rats].

OBJECTIVE: To observe the effect of liver-soothing and mental-activity-regulating (LSMAR) needling on behavior reactions and contents of serum calcitonin gene-related peptide (CGRP), substance P (SP), interleukin-1 ß (IL-1 ß) and tumor necrosis factor-α (TNF-α) in migraine rats, so as to explore its mechanism underlying relief of migraine. METHODS: Thirty-two male Wistar rats were randomly divided into control, model, LSMAR needling and conventional needling groups (n=8 rats in each). The migraine model was established by hypodermic injection of glyceryl trinitrate (5 mg/kg) at the napex. Acupuncture preconditioning was conducted once daily for 8 days before modeling. Acupuncture needles were inserted into "Baihui" (GV 20), and bilateral "Fengchi" (GB 20), "Neiguan" (PC 6) and "Taichong" (LR 3), manipulated for a while and retained for 30 min. The rats' behavioral changes (times of head scratching, tail-biting, cage-crawling, and to- and fro-movement in 30 min) were scored (one symptom = one point) before modeling, after modeling, and after intervention. The concentrations of CGRP, SP, IL-1 ß, TNF-α in serum were assayed by enzyme-linked immunosorbent assay (ELISA). RESULTS: After modeling, the behavioral scores were significantly increased in the migraine model rats relevant to the control group (P<0.05). Whereas after the treatment, the behavior scores were considerably decreased during 60-90 min and 120-150 min of the measuring period in both LSMAR and conventional needling groups compared with the model group (P<0.05). The concentrations of CGRP, SP, IL-1 ß and TNF-α were significantly higher in the model group than in the control group (P<0.05), and notably lower in both LSMAR and conventional needling groups than in the model group (P<0.05). The therapeutic effect of LSMAR was markedly superior to that of conventional needling in down-regulating the concentrations of CGRP, SP, IL-1 ß and TNF-α (P<0.05). CONCLUSION: Acupuncture preconditioning can effectively relieve pain in migraine rats possibly by decreasing the concentrations of CGRP, SP, IL-1 ß and TNF-α in the peripheral blood, and the therapeutic effect of LSMAR is evidently superior to that of conventional needling.

[Study on "Hegu (LI 4) regulates face and mouth" based on palmomental reflex].

OBJECTIVE: To explore the correlation between hand and face-mouth, so as to provide nerve reflex basis for the theory "Hegu (LI 4) regulates face and mouth". METHODS: Seven hundred and sixty-three participants who met the inclusive criteria were divided into different age groups. The skin around participants' thenar eminence was gently scraped to be observed whether there was an involuntary movement around the face or mouth, which was palmomental reflex. The results of palmomental reflex were recorded. RESULTS: The total occurrence rate of palmomental reflex was 46.26%. For those who were 0 to 1 years old, the palmomental reflex was all positive; for those who were 21 to 36 years old, the positive rate was 20.45%, which was the lowest; for those who were 65 to 85 years old, more than half of them were positive. The majority of those who were 0 to 2 years old were bilateral positive palmomental reflex, while the majority of those who were 65 to 85 years old were unilateral positive palmomental reflex. CONCLUSION: There is a certain connection between hand and face-mouth. The occurrence rate of palmomental reflex changes from high to low over age increasing, and then changes from low to high with the aging, presenting a "high-low-high" U-shaped curve, which is possible related to the growth and recession of nervous system.

[Overview of researches on the underlying mechanism of that "Hegu (LI 4) is indicated for orofacial disorders"].

It has been well documented in Chinese acupuncture medicine that "Hegu (LI 4) is indicated for orofacial problems". In the present paper, the authors analyze their correlation from the learning of modern medicine and results of recent experimental studies instead of traditional meridian theory of acupuncturology. The afferent nerve fibers from the LI 4 region and the orofacial part ascend to the spinal cord, nucleus of solitary tract, reticular formation, thalamus and the cerebral cortex, respectively, and overlap in the thalamus, cerebral cortex, etc. Under the circumstances, the interaction and functional integration of the afferent signals from LI 4 acupoint and the orofacial region may occur in the central nervous system. In addition, many relevant neuroactive substances (for example, serotonin, substance P, enkephalin, y-aminobutyric acid, glycine, calcitonin gene-related peptide, etc.) released from the sensory and motor neurons in the corresponding cerebral regions may constitute part of the substantial basis of that "Hegu (LI 4) is indicated for many orofacial disorders".
