Acupuncture for cervical dystonia associated with anxiety and depression: A case report.

BACKGROUND: Cervical dystonia (CD) is a type of muscle tone disorder that usually occurs in the neck muscles. Due to the intermittent or continuous involuntary contraction of the neck muscles, the head and neck are twisted and skewed and some postural abnormalities occur. Long-term abnormal posture or pain can cause negative emotions in patients, which can affect their quality of life. CASE SUMMARY: This case report included a 37-year-old woman who was diagnosed with CD associated with anxiety and depression; the accompanying symptoms were head and neck tilt of approximately 90° to the right and mental abnormality. After two courses of acupuncture treatment, the patient's head and neck can be maintained in a normal position, and the negative emotions can be relieved. CONCLUSION: This case indicates that acupuncture can effectively improve CD and the emotional state and quality of life of patients, making it an effective alternative treatment for the condition.

["Huayu Tongluo" moxibustion improves learning-memory ability and promotes myelin regeneration by regulating Sonic Hedgehog signaling pathway in vascular dementia rats].

OBJECTIVE: To investigate the effect of "Huayu Tongluo" (resolving blood stagnation to dredge meridian-collaterals) moxibustion on remyelination and Sonic Hedgehog (Shh) signaling pathway in the corpus callosum of vascular dementia (VD) rats, so as to explore its mechanisms underlying improvement of VD. METHODS: Male Wistar rats were randomized into sham-operation, model, medication and moxibustion groups, with 12 rats in each group.The VD model was established by bilateral common carotid artery occlusion. Moxibustion was applied to "Shenting"(GV24), "Baihui"(GV20) and "Dazhui"(GV14) for 20 min once a day, 7 d as a treatment course, for 3 courses, with one day's rest between every two courses. Rats of the medication group were treated by gavage of 10 mg/kg of chloromastine solution once a day, and the course of treatment was the same as that of the moxibustion group. The rat's learning-memory ability was assessed by Morris water maze test (escape latency). The neurological deficits were evaluated by using Longa's scale.The mRNA and protein expressions of Shh and Gli1 in the corpus callosum were measured by quantitative real-time fluorescence PCR and Western blot, separately. The ultrastructure of the myelin sheath and myelinated axons was observed under transmission electron microscopy (TCM). RESULTS: Compared with the sham-operation group, the neurologic score and escape latency were significantly increased and prolonged (P<0.01), and the mRNA and protein expression levels of Shh and Gli1 and the number of myelinated axons were obviously decreased in the model group (P<0.01). In comparison with the model group, the escape latency was apparently shortened (P<0.05), while the mRNA and protein expression levels of Shh and Gli1 as well as the number of myelinated axons were strikingly increased in both moxibustion and medication groups (P<0.01). Results of TCM showed that in the model group, the arrangement of myelin coil structures was sparse and fuzzy, and some structures were bulged and disbanded. The oligodendrocytes were irregular, and the number of myelin sheath was rare. These situations were relatively milder in both moxibustion and medication groups. CONCLUSION: "Huayu Tongluo" moxibustion can promote the differentiation and maturation of oligodendrocyte precursor cells after cerebral ischemia by regulating the expressions of Shh and Gli1 in Shh signaling pathway, thus promoting the regeneration of cerebral white matter myelin sheaths in VD rats, which may contribute to improving learning-memory ability.

[Roles of processing and compatibility in antidepression of Sini Powder:a metabonomics study].

The antidepressant mechanism of Sini Powder was investigated by metabonomics based on UHPLC-Q-TOF-MS, and the roles of processing and compatibility in the antidepression of Sini Powder were discussed in the present study. The chronic unpredictable mild stress(CUMS) model of depression was induced in the model group, the Bupleuri Radix group, the Paeoniae Radix Alba group, the herb-pair group(Bupleuri Radix-Paeoniae Radix Alba), the Sini Powder group, and the vinegar-processed Sini Powder group(Bupleuri Radix and Paeoniae Radix Alba were vinegar-processed). After the establishment of the model, the rats in each group were continuously administered with corresponding drugs(ig) at a dose of 9.6 g·kg~(-1) for eight days [the rats in the model group and the normal group(without model induction) received the same volume of normal saline at the same time]. Following the last administration, the differential metabolites were identified to analyze metabolic pathways based on the rat plasma samples collected from each group. A total of sixteen potential biomarkers were identified. The metabolites with significant changes were involved in many biological metabolic pathways, such as amino acid metabolism, pentose phosphate pathway, glycerol phospholipid metabolism, sphingolipid metabolism, and purine metabolism. After drug intervention, some biomarkers returned to normal levels. Further comparisons of processing and compatibility revealed that the vinegar-processed Sini Powder group had the most total metabolic pathways where differential metabolites were returned to normal. Compared with the individual herbs, the herb-pair significantly improved the recovery of differential metabolites in the pentose phosphate and purine metabolic pathways. Compared with the Sini Powder, the vinegar-processed Sini Powder facilitated the recovery of differential metabolites in the arginine biosynthesis, and pyrimidine and pentose phosphate metabolic pathways. As indicated by the results, Sini Powder may interfere with depression by regulating lipid and nucleotide metabolisms. The processing and compatibility of Chinese herbal medicines can potentiate the intervention on depression by regulating nucleotide, energy, and amino acid metabolisms to a certain extent.

[Effect of electroacupuncture preconditioning on neuronal activities in lateral hypothalamus area of myocardial ischemia reperfusion injury rats].

OBJECTIVE: To observe the effect of electroacupuncture (EA) preconditioning of "Shenmen" (HT7)-"Tongli" (HT5) segment of the Heart Meridian on neuronal electrical activities of lateral hypothalamus area (LHA) in rats with myocardial ischemia reperfusion injury (MIRI), so as to investigate its possible mechanism underlying improvement of MIRI. METHODS: Twenty-four SD rats were randomly divided into sham, model, EA and damage + EA (D+EA) groups, with 6 rats in each group. The MIRI model was established by occlusion of the anterior descending branch (ADB) of the left coronary artery for 30 min, followed by reperfusion for 2 h. In the sham operation group, the ADB was only threaded beneath the artery without ligation. EA (2 Hz, 1 V) was applied to bilateral HT7-HT5 for 20 min, once daily for 7 days. In the D+EA group, FN was injected with 0.4 µL of 1 g/L kainic acid solution. Electrocardiogram (ECG) of the neck-thoracic lead was recorded by using PowerLab. The electrical activities of the LHA region were recorded by the implanted microelectrode array (2×4) and Plexon multi-channel acquisition system. Cluster analysis of neuronal signals was carried out by Offline Sorter software. The discharge waveforms, autocorrelation and cross-correlation of neuronal activities were analyzed by using Neuro Explorer software. RESULTS: Compared with the sham group, the ECG-ST height was significantly increased (P<0.05), the discharge frequency of pyramidal neurons was significantly reduced (P<0.01), while the discharge frequency of interneurons was increased (P<0.01) in the model group. After EA treatment, the ECG-ST height was significantly decreased (P<0.05), the discharge frequency of pyramidal neurons was significantly increased (P<0.01) relevant to the model group. In comparison with the EA group, the ECG-ST height in the D+EA group was significantly elevated (P<0.05), whereas the discharge frequency of pyramidal neurons was significantly decreased (P<0.01). The discharge frequency of interneurons was kept increasing after MIRI. Real-time spectrum analysis showed that the local field potential spectrum energy of the EA group was significantly lower than that of the model group and the D+EA group. CONCLUSION: EA preconditioning of Heart Meridian can significantly increase the discharge frequency of LHA excitatory pyramidal neurons and reduce the energy of the local field potential spectrum, which maybe one of the important mechanisms of EA in anti -MIRI.

[Effect of electroacupuncture preconditioning on the contents of dopamine and 5-hydroxytryptamine in lateral hypothalamus area and cerebellar fastigial nucleus of rats with myocardial ischemia-reperfusion injury].

OBJECTIVE: To observe the effect of electroacupuncture (EA) preconditioning at heart meridian acupoints on the contents of dopamine (DA) and 5-hydroxytryptamine (5-HT) in lateral hypothalamus area (LHA) and cerebellar fastigial nucleus (FN) in the rats with acute myocardial ischemia-reperfusion injury (MIRI), and explore the role and mechanism of LHA and FN in the effect of EA at heart meridian acupoints against acute MIRI. METHODS: Sixty SD rats were randomly divided into a sham-operation group, a model group, an EA heart meridian group and an EA lung meridian group, 12 rats in each group, as well as an LHA plus heart meridian group (damage of bilateral LHA) and an FN plus heart meridian group (damage of bilateral FN), 6 rats in each one. Three days after nucleus destruction, EA was applied to "Shenmen" (HT 7) and "Tongli" (HT 5) in the EA heart meridian group, the LHA plus heart meridian group and the FN plus heart meridian group and EA was applied to "Taiyuan" (LU 9) and "Lieque" (LU 7) in the EA lung meridian group, with 1 V in stimulating voltage and 2 Hz in frequency, lasting 20 minutes each time, once a day, for consecutively 7 days before model replication. Except in the sham-operation group, MIRI rat models were duplicated by ligation of the left anterior descending branch of the coronary artery in the rest groups. Using Power lab physiological recorder, ST segment displacement value was recorded before modeling, 30 min after ligation and 120 min after reperfusion separately. The high performance liquid chromatography-electrochemical detection and analysis system was adopted to determine the contents of DA and 5-HT in LHA and FN dialysate after rat modeling in each group. RESULTS: In comparison of ST segment displacement value 30 min after ligation and 120 min after reperfusion among groups, the value in the model group was higher than that in the sham-operation group (P<0.01), those in the EA heart meridian group, the LHA plus heart meridian group, the FN plus heart meridian group and the EA lung meridian group were lower than those in the model group successively (P<0.01) and those in the EA heart meridian group were lower than those in the EA lung meridian group, the LHA plus heart meridian group and the FN plus heart meridian group successively (P<0.01). The contents of DA and 5-HT in FN and LHA in the model group were lower than those in the sham-operation group (P<0.01). Except in the groups with nucleus lesions, the contents of DA and 5-HT in FN and LHA of each intervention group were higher than those in the model group (P<0.01), the contents of DA and 5-HT in FN in the EA heart meridian group were higher than those in the EA lung meridian group and the LHA plus heart meridian group (P<0.01) and the content of 5-HT in LHA was higher than those in the EA lung meridian group and the FN plus heart meridian group (P<0.01) separately, the content of DA in LHA was higher than that in the EA lung meridian group (P<0.01). CONCLUSION: EA preconditioning at heart meridian acupoints can effectively alleviate myocardial injury in acute MIRI rats, during which, DA and 5-HT in LHA and FN may be the important material basis.
