ABSTRACT
Objective To understand the spatial and temporal distribution characteristics of dengue fever in China from 2011 to 2018, and predict the incidence of dengue fever in China in 2019. Methods Based on the case data of dengue fever in China from 2011 to 2018 in the Chinese Disease Prevention and Control Information System, the trend of dengue fever was described and predicted by using the autoregressive integrated moving average model (ARIMA) with R 3.6.0 software. Based on the data of the incidence of dengue fever in the country, provinces and cities from 2011 to 2016 provided by the national scientific data sharing platform for population and health, global and local spatial autocorrelation analysis was performed using GeoDa 1.12 software to determine the dengue fever hotspots. Results The incidence of dengue fever was 14 302 in 2019, showing no disease outbreaks. The incidence of dengue fever in 2012(Moran’s I=-0.088, P=0.037), 2013(Moran’s I=-0.121, P=0.040) and 2014(Moran’s I=-0.076, P=0.045) showed a global spatial negatively correlaton. In 2016(Moran’s I=0.078, P=0.048), the incidence of dengue fever was positively correlated with global space. The results of local autocorrelation analysis showed that the high incidence of dengue fever was mainly in the southeast coastal areas of China. Conclusions In 2019, the epidemic of dengue fever in China showed no obvious fluctuation trend, and the epidemic situation showed spatial clustering distribution.
ABSTRACT
Objective To explore the effects of traditional exercise therapy, such as Taiji Quan, on motor function of lower limbs in stroke patients.Methods From March, 2014 to March, 2016, 105 stroke patients were divided into control group (n = 35), Qigong group (n = 35) and Taiji group (n = 35). All the patients received routine rehabilitation. In addition, the Taiji group exercised with modified 24 type Taiji Quan, while the Qigong group exercised with Baduanjin. They were assessed with Fugel-Meyer Assessment-lower extremities (FMA-LE), and integral electromyography (iEMG) and co-contraction ratio (CR) of tibialis anterior muscle and gastrocnemius were recorded with surface electromyography, before, four weeks and eight weeks after treatment.Results There were 21 cases in the control group, 23 in the Qigong group and 28 in the Taiji group finishing the exercise. At the end of the 8th week, the score of FMA-LE was more in the Taiji group than in the control group (P ＜0.05). The i EMG of tibialis anterior muscle as dorsiflexsion was more in both the Taiji group and the Qigong group than in the control group (P ＜ 0.05). The CR of tibialis anterior muscle was less in the Taiji group than in both the control group and the Qigong group (P ＜ 0.05).Conclusion Both Taiji Quan and Qigong exercise may promote the activities of muscle of legs in the patients with stroke, while Taiji Quan seems to be better in the coordination between active muscles and antagonistic muscles.
