Objective: To explore the molecular biological mechanism of acupuncture in intervening visual deprivation.
Methods: Forty-eight 2-week old Wistar rats were randomly divided into a normal group, a model group, and 6 acupuncture groups (group C1: acupuncture at the unaffected side in early stage; group C2: acupuncture at the affected side in early stage; group D1: acupuncture at the unaffected side in mid-stage; group D2: acupuncture at the affected side in mid-stage; group E1: acupuncture at the unaffected side in late stage; group E2: acupuncture at the affected side in late stage) by the random number table, 6 rats in each group. Rats in the normal group didn’t receive any interventions. The rat model of deprivation amblyopia was established by unilateral eyelid suture in the model group and each acupuncture group. After successful modeling, rats in model group didn’t receive any treatments; rats in the acupuncture groups received acupuncture intervention which began respectively on the 3rd, 12th and 21st day after modeling. Pattern visual evoked potential (P-VEP) and N-methy D-aspartatreceptor-1 (NMDAR1) mRNA expression in visual cortex area 17 were detected at the end of acupuncture intervention in each group.
Results: After the intervention, the P-VEP waveform was significantly changed, with a significantly delayed P100 value (P<0.01) and significantly decreased amplitude of N45-P100 in the model group versus the normal group (P<0.01); the P-VEP waveform was significantly improved, with obviously earlier P100 (P<0.01) and increased amplitude of N45-P100 (P<0.05) in each acupuncture group versus the model group. The improvement effect of acupuncture on the P-VEP waveform in group C1 and C2 was more significant than that in group D1, D2, E1 and E2. The expression of NMDAR1 mRNA of the rat visual cortex area 17 in the model group was significantly lower than that in the normal group (P<0.01); and the expression of NMDAR1 mRNA in the visual cortex area 17 of each acupuncture group was significantly higher than that in the model group (P<0.05); the effect of acupuncture on NMDAR1 mRNA expression in group C1 and C2 was more significant than that in group D1, D2, E1 and E2; and the effect of acupuncture on NMDAR1 mRNA expression was better in group C2 than in group C1 (P<0.05); there was no significant difference in the expression of NMDAR1 mRNA between group D1 and D2, neither between E1 and E2 (P>0.05).
Conclusion: P-VEP waveform is abnormal and NMDAR1 mRNA expression in visual cortex area 17 is decreased in rats with monocularly-deprived amblyopia. Acupuncture in the sensitive period can significantly regulate the abnormal P-VEP waveform and the down-regulate the NMDAR1 mRNA expression of the visual cortex of rats with monocularly-deprived amblyopia. Early treatment in the sensitive period should be the key to obtaining the curative effect.

Objective To assess the therapeutic efficacy of trigger points (TrPs) combined with acupoints by acupuncture for subjective tinnitus (ST);To discuss the correlation of TrPs acupuncture inactivation and the releasing of symptom. Methods Sixty patients with ST were randomly divided into trial group and control group, 30 cases in each group. Those in trial group were acupunctured by TrPs combined with acupoints, and those in control group received regular acupuncture treatment. The scores of tinnitus severity assessment were available for effect evaluation after 3 treatment course. The size and tenderness degree of TrPs contraction knots were checked, and TrPs local thermal infrared spectrum was compared by infrared camera. Results The post-treatment tinnitus severity scores had significant difference compared with pre-therapy in each group (P<0.01). The total effective percentage of trial group with 93.33%(28/30) was obviously higher than control group with 86.67%(26/30) (P<0.05). The post-treatment and pre-therapy contraction knots size, tenderness and temperature difference of TrPs within trial groups had a very significant difference (P<0.01), and difference of tenderness and temperature of patients’ TrPs had a positive correlation with the difference of tinnitus severity scores before and after treatment (P<0.01). The contraction knots area of TrPs had not significant correlation with the difference of tinnitus severity scores (P>0.05). Conclusion TrPs combined with acupoints by acupuncture for ST patients are better than conventional acupoints in improving clinical symptoms. The deactivation of TrPs is closely related to tinnitus symptoms, therefore, temperature and tenderness of TrPs can be employed to assist in the diagnosis, or evaluated the tinnitus severity and therapeutic efficacy.

Objective: To investigate the electrophysiological mechanism of acupuncture for the visual cortex plasticity during the sensitive period. Methods: Fifty 2-week-old Wistar rats were randomly divided into a blank control group, a model group, an early-stage acupuncture group, a middle-stage acupuncture group and a late-stage acupuncture group, 10 rats in each group. Monocular deprivation amblyopia models were prepared in rats except those in the blank control group by unilateral eyelid suture. After successful modeling, no treatment was applied to the rats in the model group. Rats in each acupuncture group were treated with acupuncture at bilateral Jingming (BL 1), Cuanzhu (BL 2), Fengchi (GB 20) and Guangming (GB 37), started from the 3rd day, 12th day or 21st day after modeling separately, once a day, for a total of 9 d treatment. The neuronal discharge frequency and action potential inter-spike interval (ISI) in the rat visual cortex area 17 of each group were measured by multi-channel microelectrode array nerve signal technique. Results: The discharge number of neurons in the visual cortex of the model group was significantly lower than that in the blank control group (P<0.05). After treatment, the discharge numbers in the early-stage acupuncture group and the middle-stage acupuncture group were significantly higher than that in the model group (P<0.05). There was no significant difference in the discharge numbers between the late-stage acupuncture group and the model group (P>0.05). The discharge number in the middle-stage acupuncture group was lower than that in the early-stage acupuncture group (P<0.05), and the discharge number of the late-stage acupuncture group was lower than that in the middle-stage acupuncture group (P<0.05). The ISI sequences of the visual cortex neurons were mainly distributed under 0.3 s in the blank control group, under 15 s in the model group, under 1 s in the early-stage acupuncture group, under 4 s in the middle-stage acupuncture group, and under 10 s in the late-stage acupuncture group, divergent in each group. Conclusion: The neuronal coding appears abnormality in the visual cortex area 17 of monocular deprivation rats, indicating that there is a plasticity change in the visual cortex neurons during the sensitive period. Acupuncture has a significant effect on the abnormal neural coding. The therapeutic efficacy is closely related to the stage to start the treatment. Early stage treatment in the sensitive period is the key to achieving the good efficacy.
