Evaluation of sports tourism competitiveness of urban agglomerations in Guangdong-Hong Kong-Macao Greater Bay Area.

In the era of experience economy, sports tourism has been emerged as a new tourism form and consumption hot spot. Evaluation of the competitiveness of sports tourism is helpful to accurately grasp the key competitive factors of sports tourism development and enhance regional sports tourism resource development, market expansion and product upgrading. This study adopted entropy-weight TOPSIS model to construct the index system of sports tourism competitiveness of urban agglomerations and investigated the sports tourism competitiveness of 11 cities in Guangdong-Hong Kong-Macao Greater Bay Area from 2016 to 2020. The obtained results showed that sports tourism development in the Greater Bay Area was unbalanced and obviously different. Guangzhou, Shenzhen and Hong Kong are competitive, Macao is average competitive and Dongguan, Jiangmen, Zhuhai, Foshan, Zhongshan, Huizhou and Zhaoqing are less competitive. Based on evolution trend, sports tourism competitiveness in Guangzhou has always been at the forefront of the Greater Bay Area, while those of Hong Kong and Macao have presented a declining trend. Also, sports tourism competitiveness in inland cities has been continuously enhanced and the development focus of sports tourism in Guangdong-Hong Kong-Macao Greater Bay Area has gradually shifted to mainland. The 11 cities of the Greater Bay Area were classified as strong, average and weak areas on the basis of their sports tourism competitiveness scores. Finally, in terms of the overall situation of Guangdong-Hong Kong-Macao Greater Bay Area and specific conditions of various cities, countermeasures and suggestions have been provided for sports tourism resource development, sports tourism service level, government functional departments, event brand building, enterprise integration, etc.

[A prospective randomized controlled study of the difference between BPPV manual reduction and automatic device reduction].

Objective:To investigate the difference between manual reduction and automatic device reduction in the treatment of benign paroxysmal positional vertigo（BPPV）, and to provide evidence-based medicine for the clinical choice of BPPV treatment. Methods:Two hundred and two BPPV patients who came to the hospital for diagnosis and treatment were collected and divided into two groups by random number table method. Group A had 102 cases for manual reduction, and group B had 100 cases for automatic device reduction. Both groups were given the same medicine-assisted treatment. All patients were followed up 7 to 10 days after reduction treatment. To evaluate the differences in the overall effective rate of treatment, visual analog scale（VAS）, incidence of adverse reactions, treatment time were compared between the two groups. Results:The overall effective rate was 98.03% and 91.00% in group A and group B, respectively, group A was slightly higher than group B（P=0.027）; the difference in VAS scores before and after treatment: group A was 6（4） points, group B was 5（3） , group A is greater than group B（P=0.002）; adverse reaction rates in groups A and B were 4.90% and 8.00%, respectively, group B was slightly higher than group A（P=0.37）; treatment time: group A 6.0（1.0） min in group A and 8.0（2.0） min in group B, group A was significantly shorter than group B（P<0.01）. Conclusion:Both manual and fully automatic device reduction can effectively improve the clinical symptoms of BPPV patients, but for physicians with extensive clinical experience it is recommended to choose manual reduction.
