Objective:To investigate the efficacy of auricular acupoint bean-embedding therapy in the treatment of residual dizziness after successful reduction of benign paroxysmal positional vertigo (BPPV) and its effect on skin sympathetic response.Methods:A total of 110 patients with residual dizziness after successful reduction of BPPV who were admitted to Wenzhou Hospital of Traditional Chinese Medicine from January 2019 to May 2021 were included in this study. They were randomly divided into control and study groups, with 55 patients in each group. Patients in the control group were treated with drugs, and those in the study group were treated with auricular acupoint bean-embedding therapy. Before and after treatment, dizziness handicap inventory (DHI) score, activities-specific balance confidence (ABC) score, and Hamilton Anxiety Scale (HAMA) score were compared between the two groups. The latency and amplitude of sympathetic skin response (SSR) were measured.Results:After 15 days of treatment, DHI scores of all dimensions in the study group were significantly lower than those in the control group ( t = 16.13-20.62, all P < 0.05). ABC score in the study group was significantly higher than that in the control group [(87.90 ± 6.01) points vs. (80.55 ± 8.73) points, t = 3.10, P < 0.05). HAMA score in the study group was significantly lower than that in the control group [(7.85 ± 1.06) points vs. (13.30 ± 2.49) points, t = 8.43, P < 0.001]. The initial latency value of SSR in the study group was significantly higher than that in the control group [(1.95 ± 0.27) ms vs. (1.67 ± 0.21) ms, and the amplitude of SSR in the study group was significantly lower than that in the control group [(1.49 ± 0.15) mV vs. (1.70 ± 0.22) mV, t = 4.73, 4.04, both P < 0.001]. The incidence of adverse reactions in the study group was significantly lower than that in the control group [0.0% (0/55) vs. 10.9% (6/55), χ2 = 4.40, P < 0.05]. Conclusion:Auricular acupoint bean-embedding therapy can effectively alleviate the symptoms of dizziness after successful reduction of BPPV, improve patient's psychological status and autonomic nerve function, which is worthy of clinical promotion.

Objective:To investigate the clinical efficacy of cognitive and behavioral therapy assisted by five-tone therapy for insomnia in sub-healthy people based on digital polysomnography observation.Methods:The clinical data of 70 sub-healthy people with insomnia who received treatment in Wenzhou Hospital of Traditional Chinese Medicine, Zhejiang University of Traditional Chinese Medicine from June 2019 to June 2021 were retrospectively analyzed. These patients were divided into a control group and an observation group ( n = 35 per group) according to different treatment methods. The control group was treated with cognitive and behavioral therapy, while the observation group was treated with cognitive and behavioral therapy assisted by five-tone therapy. Clinical efficacy, syndrome score, sleep quality, quality of life, and digital polysomnography index levels were compared between the two groups. Results:After 4 weeks of treatment, the total effective rate in the observation group was 97% (29/35), which was significantly higher than 83% (34/35) in the control group ( χ2 = 8.77, P = 0.012). The syndrome score in the observation group was (3.26 ± 2.12) points, which was significantly lower than (6.00 ± 1.68) points in the control group ( t = 5.99, P < 0.001). The Pittsburgh Sleep Quality Index score in the observation group was (3.46 ± 2.36) points, which was significantly lower than (5.60 ± 3.35) points in the control group ( t = 3.09, P = 0.003). The WHOQOL-BREF score in the observation group was (67.00 ± 5.26) points, which was significantly higher than (61.54 ± 4.63) points in the control group ( t = 4.61, P < 0.001). Total sleep time, sleep efficiency, and sleep latency in the observation group were superior to those in the control group ( t = 4.56, 5.57, 3.96, all P < 0.05). Conclusion:Cognitive and behavioral therapy assisted by five-tone therapy can markedly reduce insomnia severity and improve the quality of life in sub-healthy people with insomnia. The evaluation of insomnia status based on digital polysomnography indicators can effectively objectively evaluate the causes of insomnia, which is of great significance for guiding clinical treatment.

Objective:To investigate the clinical value of three-dimensional arterial spin marker imaging(3D-ASL) for evaluating collateral circulation compensatory status in patients with cerebral infarction.Methods:A total of 24 patients with cerebral infarction who were treated at Wenzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang University of Chinese Medicine from September 2017 to January 2019 were examined by 1.5-T high-field MR scanner.The changes of cerebral blood flow(CBF) between the infarcted area and the contralateral normal area were compared when the labeled delay time(PLD)=1.5s and PLD=2.5s, and the patients were divided into the group with strong collateral circulation compensation and the group with weak collateral circulation compensation according to the difference in lesion area measured by 3D-ASL(PLD=1.5s and 2.5s). The changes of national institutes of health stroke scale(NIHSS) score and Bathel index at admission and 15 days after admission were compared.Results:3D-ASL measurement of PLD=1.5s showed that the CBF value in the infarcted area was (33.70±20.83)mL/(100g×min), which was significantly lower than that in the contralateral normal area(PLD=1.5s)[(49.93±13.13)mL/(100g×min)]( t=3.229, P<0.05). When PLD=2.5s, ASL measurement results showed that the CBF value in the infarcted area increased significantly[(58.26±23.50)mL/(100g×min) vs.(33.70±20.83)mL/(100g×min)]( t=3.831, P<0.05), and the CBF value in the contralateral normal area also increased significantly[(68.29±14.03)mL/(100g×min) vs.(49.93±13.13)mL/(100g×min)]( t=4.681, P<0.05). At this time, the CBF value in the infarcted area was still significantly lower than that in the contralateral normal area[(58.26±23.50)mL/(100g×min) vs.(68.29±14.03)mL/(100g×min)]( t=1.795, P<0.05). On the day of admission, the BI index of patients in the weak collateral circulation compensation group(12 cases) was significantly higher than that in the strong collateral circulation compensation group(12 cases)[(90.42±10.50) vs.(67.92±27.57)]( t=2.642, P<0.05), and the NIHSS score was significantly lower than that in the strong collateral circulation compensation group[(1.25±1.01) vs.(3.83±3.62)]( t=2.378, P<0.05). After 15 d of admission, there were no significant differences in BI index and NIHSS score between the two groups(all P>0.05). Conclusion:3D-ASL with different delay time can effectively and intuitively reflect collateral circulation compensation of patients with cerebral infarction, and it has very important reference value for the evaluation of patients' disease and the formulation of clinical treatment plan.
