ABSTRACT
@#Abstract: Objective To analyze the vaccination status of SARS-CoV-2 in children, and explore the relationship between SARS-CoV-2 vaccination and COVID-19 in children. Methods A retrospective study was conducted to analyze the clinical data of 335 cases of SARS-CoV-2 Omicron variant infection from February 15, 2022 to March 18, 2022 in Shenzhen Third People's Hospital. Results Among 335 children with SARS-CoV-2 infection, 174(51.9%) cases were vaccinated with the SARS-CoV-2 vaccine; 33(31.4%) cases were vaccinated in the 3-<6 years old group; 141(61.3%) cases were vaccinated in the 6-<14 years old group. There was a statistically significant difference in the proportion of SARS-CoV-2 vaccination between the 6-<14 years old group and the 3-<6 years old group (χ2=26.1, P<0.05). In the study cohort, 3-<6 years old group and 6-<14 years old group, there was no significant difference in the incidence of COVID-19 in the vaccinated group compared with the unvaccinated group (P>0.05). In the study cohort, the proportion of confirmed cases of 1 dose of SARS-CoV-2 vaccine and 2 doses or more of SARS-CoV-2 vaccine was 89.5% (68 cases) and 77.6% (76 cases), respectively; in the 6~<14 years old group, the proportion of confirmed cases of 1 dose of SARS-CoV-2 vaccine and 2 doses or more of SARS-CoV-2 vaccine was 90.0% (54 cases) and 76.5% (62 cases), respectively; the differences were statistically significant (χ2=4.264, P<0.05; χ2=4.279，P<0.05). The IgG levels of 18.28 (6.61, 55.2) AU/mL and 58.3 (25.85, 131.41) AU/mL in the study cohort who were vaccinated for 1 dose, 2 doses and more, respectively; the IgG levels of 20.13 (8.33, 44.33) AU/mL and 56.57 (25.85, 150.07) AU/mL in the 6~<14 years old group who were vaccinated for 1 dose, 2 doses and more, respectively; and the differences were statistically significant (Z=-4.37, P<0.05; Z=-3.96, P<0.05). Conclusions Children who received 2 doses of SARS-CoV-2 vaccine have a lower incidence of COVID-19 and higher levels of SARS-CoV-2 antibodies compared with who received 1 dose . It is recommended that children are advised to be vaccinated against the COVID-19.
ABSTRACT
Objective@#To investigate the effect of exercise intervention on sleep quality of female college students with anxiety, and to further explore the mediating effect of negative emotions in this association.@*Methods@#Seventy female college students were randomly divided into experimental group (34 patients) and control group(36 patients). The experimental group received eight-week aerobic exercise and yoga training. The control group received no training. Sleep Quality Scale, Negative Emotion Scale and Anxiety Self-rating Scale were used to assess the level of sleep and negative emotion before and after exercise intervention.@*Results@#After exercise intervention, sleep quality (4.31±1.26), anxiety (36.41±7.32) and negative emotion (2.37±0.50) in the experimental group significantly improved(P<0.01), no similar changes were found in the control group(P<0.05). By examining the mediating effects, negative emotions played a partial mediating role in the association between exercise and sleep quality(t=6.77, P<0.01).@*Conclusion@#Exercise intervention significantly improved the quality of sleep and negative emotion among female college students with anxiety. Negative emotions play a partial role in the positive effect of exercise on sleep quality.
ABSTRACT
OBJECTIVE@#To explore the effect of acupuncture at the "reflection points" of affected side on the peripheral facial paralysis in acute phase.@*METHODS@#Ninety patients with peripheral facial paralysis in acute phase were randomly divided into a reflection group (group A), a conventional acupuncture group (group B) and a physiotherapy group (group C), 30 cases in each group. The same basic medication were given in all three groups. In the group A, acupuncture at "reflection points" of the affected side and local acupoints in acute phase, such as Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Xiaguan (ST 7), Yangbai (GB 14), Taiyang (EX-HN 5), etc. were applied. The electroacupuncture was added in the stationary phase, and Zusanli (ST 36) was added in the recovery phase. In the group B, acupuncture at Yifeng (TE 17) of the affected side in acute phase and local acupoints, such as Dicang (ST 4), Jiache (ST 6), Quanliao (SI 18), Xiaguan (ST 7), Yangbai (GB 14), Taiyang (EX-HN 5), etc. were applied. The electroacupuncture was added in the stationary phase, and Zusanli (ST 36) was added in the recovery phase. In the group C, ultrashort wave on Yifeng (TE 17) of the affected side in acute phase was applied, and the treatment in the stationary phase and the recovery phase was the same as the group B. The treatment was given once every day, 5 times as one course for 4 courses. The House-Brackmann (H-B) grading scale, facial disability index scale, the symptom and physical score integral scale were used to score before and after treatment, and the clinical effects of the three groups were compared.@*RESULTS@#After treatment, the functional grade of H-B facial nerve was better than that before treatment in the three groups (0.05). After treatment, the course of treatment required to reflect the healing in the group A was shorter than that in the group B and the group C (0.05). The scores of symptoms and signs in the three groups were lower than those before treatment (0.05). H-B facial nerve function grading scale and facial disability index (FDI) scale were used as the evaluation criteria, the curative rate was 66.7% (20/30) in the group A, 50.0% (15/30) in the group B and 46.7% (14/30) in the group C, the curative rate in the group A was better than the other two groups (<0.05). The curative and markedly effective rate in the group A was 83.3% (25/30), 70.0% (21/30) in the group B and 63.3% (19/30) in the group C, the curative and markedly effective rate in the group A was better than the other two groups (<0.05). The scores of symptoms and signs were used as the evaluation criteria, the curative rate was 66.7% (20/30) in the group A, 50.0% (15/30) in the group B, and 46.7% (14/30) in the group C. The curative rate in the group A was better than the other two groups (<0.05).@*CONCLUSION@#Compared with general acupuncture and physiotherapy, acupuncture at the "reflection points" of the affected side on the peripheral facial paralysis in acute phase could shorten the course of treatment and improve the curative effect.
