The association between rotavirus diarrhea in children and atmospheric pressure in Guangzhou City from 2012 to 2020 / 中国学校卫生

Objective@#To explore the relative risks of rotavirus diarrhea after exposure to different levels of atmospheric pressure in children in Guangzhou City, so as to provide reference for improving public awareness of high atmospheric pressure exposure.@*Methods@#The study used the China Notifiable Communicable Diseases Network System and China Meteorological Science Data Sharing Service Network to collect meteorological data and data relating to daily cases of rotavirus diarrhea in children at Guangzhou Women and Children s Medical Center from 2012 to 2020. The association between rotavirus diarrhea and atmospheric pressure was analyzed using distributed lag non linear models (DLNM). The relative risks of different sex and age sub groups exposed to different atmospheric pressures were also evaluated.@*Results@#A total of 18 587 cases of rotavirus diarrhea were reported from 2012 to 2020, among which 11 662 cases (62.7%) were boys, and 12 582 cases (67.7%) were children aged 6 to 24 months old, which represented the highest proportion. The results of the DLNM showed that the relative risk of rotavirus diarrhea was the highest on the day of exposure to extreme high atmospheric pressure ( RR =1.50, 95% CI =1.24-1.82, P <0.05) and the effect could last for 28 days. Risk of rotavirus diarrhea was low for exposure to low pressure within 2 weeks ( P <0.05). During extremely high atmospheric pressure weather, RR was higher in girls ( RR =3.31, 95% CI =1.46-7.49， P <0.05) than that in boys ( RR =1.98, 95% CI =0.96-4.07， P >0.05). Among different age sub groups, RR was the highest in children aged 24 to 60 months after exposure to the highest level of atmospheric pressure exposure ( RR =3.36, 95% CI =1.27-8.89, P <0.05).@*Conclusion@#In Guangzhou, exposure to high pressure increases the risk of rotavirus diarrhea in children. In the future, public awareness should be raised regarding the risk after exposure to high atmospheric pressure.

Effects of low power laser irradiation in nasal cavity on cerebral blood flow perfusion of patients with brain infarction / 中华物理医学与康复杂志

Objective To study the effects of low power laser irradiation in nasal cavity on cerebral blood flow and cerebral function in patients with brain infarction. Methods Thirty-nine patients with cerebral infarction were divided into a intravenous laser irradiation group and a laser irradiation in nasal cavity group. For the group of intravenous irradiation (ILIB group,18 cases), the patients lay on the bed with their heads fixed and were treated with intravenous laser irradiation for 30 min. Both before and after the therapy they received a SPECT cerebral perfusion imaging separately. For the group of laser irradiation in nasal cavity (LINC group,21 cases), the patients received laser irradiation in nasal cavity for 30 min and also SPECT cerebral perfusion imaging tests both before and after therapy. BFCR% model was used to quantify the blood flow of the focal and mirror regions. Results SPECT showed that there was significant improvement in perfusion of the entire brain and cerebral function in both ILIB and LINC groups after 30 minutes of treatment,each compared to those before treatment; the changes in the focal rCBF and cerebral function were much more obvious (P0.05). BFCR% in focal region was significantly higher than that in mirror region (P0.05). Conclusion Low power laser irradiation in nasal cavity can improve the focal rCBF and cerebral function of the patients with brain infarction, which is similar to that of the ILIB.
