Yunmen (LU 2) combined with neck-seven-acupoint acupuncture for arm numbness caused by cervical spondylotic radiculopathy: A case report.

RATIONALE: Cervical spondylotic radiculopathy (CSR) is a common sensory, motor, and reflex disorder. Numbness, a common subjective symptom of CSR, lacks objective quantitative indicators and recognized effective treatments, but is also difficult to recover from. We present a case report describing a traditional acupuncture treatment for CSR, utilizing a special acupuncture method and point, namely the Yunmen point. PATIENT CONCERNS: A 40-year-old woman presented with unilateral arm numbness caused by CSR. DIAGNOSES: A diagnosis of CSR was made in the orthopedic department of a local hospital. INTERVENTIONS: We attempted acupuncture at the Yunmen (LU 2) acupoint combined with neck-seven-acupoint under computed tomographic guidance. OUTCOMES: After 10 times treatment sessions, the patient no longer experienced weakness, coldness, or numbness in the affected upper limb. In addition, the stiffness in the neck and shoulders was reduced. On physical examination, the patient's left brachial plexus traction test was negative; reassessment of the CSR-20-point score scale showed a perfect score, and the visual analog scale score was 0. LESSONS: Our report indicates that acupuncture at the LU 2 acupoint combined with neck-seven-acupoint is effective in treating numbness and coldness of the arm, and other neurological symptoms caused by cervical spondylosis. Moreover, with the appropriate acupuncture technique, the risk of acupuncture at the LU 2 acupoint can be minimized.

[Effect of Magnolol on Proliferation and Apoptosis of HL-60 Cells and Its Molecular Mechanism].

OBJECTIVE: To investigate the effect of magnolol on proliferation and apoptosis of HL-60 cells and its mechanism. METHODS: MTT assay was used to measure the proliferation of HL-60 cells after treatment with different concentration of magnolol (5, 10, 20, 40, 80 and 160 µg/ml). The morphological changes of HL-60 cells were examined by light microscopy, and DAPI staining was performed to observe the nuclear morphology of HL-60 cells. The early cell apoptosis was detected by flow cytometry with Annexin V-FITC/PI double-staining. RT-PCR was carried out to examine the mRNA expression of BAX and BCL-2. Western blot was performed to detect the protein expression of caspase family. RESULTS: The magnolol inhibited HL-60 cell proliferation, and the inhibitory rate of cell proliferation increased significantly in a dose- and time- dependent manner (P < 0.05). HL-60 cells became small, even apoptotic bodies appeared after treatment with magnolol. In addition, nuclear condensation or fragmentation could be observed, which is the typical morphological features of apoptosis. When HL-60 cells were treated with 40 µg/ml of magnolol for 24 h, the ratio of early apoptotic cells reached to (11.7 ± 2.4) %, which was significant different from control (1.4 ± 1.1) % (P < 0.05). RT-PCR results showed that treatment of HL-60 cells with magnolol up-regulated the expression of BAX, whereas down-regulated the expression of BCL-2. Western blot results showed that the cleavages of caspase-3, -8 and -9 were significantly enhanced by magnolol. CONCLUSION: The magnolol can significantly inhibit the proliferation of HL-60 cells and induce the apoptosis of HL-60 cells, which may occur through up-regulation of BAX, down-regulation of BCL-2 and the activation of caspases.
