Objective To investigate the clinical therapeutic effect of different frequency electroacupuncture on poststroke hemidysesthesia.Methods Sixty patients with poststroke hemidysesthesia were randomly allocated to treatment and control groups, 30 cases each. Both groups received electroacupuncture at the same points. The electroacupuncture frequency was 100 Hz in the treatment group and 1 Hz in the control group. The clinical therapeutic effects were evaluated in the two groups at 30 days after treatment.Results The total efficacy rate and the cure and marked efficacy rate were 93.3 and 80.0, respectively, in the treatment group and 86.0% and 43.3%, respectively, in the control group. There was no significant difference in the total efficacy rate between the two groups (P<0.05).There was a statistically significant difference in the cure and marked efficacy rate between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the limb dysesthesia score in the two groups (P<0.05). There was a statistically significant post-treatment difference in the limb dysesthesia score between the treatment and control groups (P<0.05).Conclusions Electroacupuncture is an effective way to treat poststroke hemidyse- sthesia. High frequency electroacupuncture is more effective than low frequency electroacupuncture.

Objective: To study the development of grip strength and its relationship with body weight, height and body composition in preschool children. Methods: Data was collected from 900 children aged 3-6 years in 4 preschools in Beijing during Sept. to Oct. of 2020. A questionnaire survey (birth weight, dietary and exercise), height, weight, bioelectrical impedance analysis of body composition and dominant hand grip strength tests were conducted. Partial correlational analysis, multivariate linear regression were used for association between grip strength and body composition. Results: The grip strength gradually increased with age, from (5.2±1.7) to (9.3±2.5)kg in boys ( F=57.93, P <0.01), and from (4.3±1.6) to (7.9±2.5)kg in girls ( F=48.77, P <0.01). Grip strength in boys were significant higher than that of girls ( t=6.42, P <0.01). The grip strength increased with weight status in boys ( F=5.35, P <0.01), with highest in obese group, followed by overweight and normal weight group. After adjusted for height, weight and birth weight, as well as maternal education, food consumption during the past week, grip strength in boys was positively correlated with fat free mass, upper limb muscle mass ( r=0.11, 0.09, P <0.05), and negatively correlated with body fat mass ( r=-0.18, P <0.05). Grip strength in girls was negatively correlated with body fat mass, and positively correlated with fat free mass ( r= -0.09, 0.09, P <0.05). Grip strength varied significantly by age, fat free mass and upper muscle mass in boys ( F=66.75, P < 0.01), and by age and fat free mass in girls ( F=150.81, P <0.01). Conclusion The grip strength can partially reflect changes in fat free mass for boys and girls, it also reflect changes in upper limb muscle mass for boys. Increases in fat free mass helps grip strength improvement.

Objective:To explore the status of early essential newborn care (EENC) implementation in four counties in western China.Methods:Based on the 18 counties from "safety newborn project", which was jointly launched by the National Health Commission (NHC) of China and United Nations Children's Fund, one county was randomly selected from Ningxia Hui Autonomous Region, and Guizhou, Sichuan and Qinghai Province, respectively (Longde county, Qinglong county, Tongjiang county, and Tongren county). Then one or two county-level birth facilities were randomly selected from each county for the field investigation from December 2020 to April 2021. Information of EENC core practice implementation was collected through questionnaires for mother-newborn dyads, and interviewees' experiences, attitudes, and needs for EENC implementation were obtained through focus group discussion and in-depth interviews with mothers. SAS 9.4 and NVivo 12.0 were used for quantitative and qualitative data analysis, then the results were integrated.Results:A total of 599 questionnaires for mother-newborn dyads were collected from the four counties, and 45 health staff and 15 mothers were interviewed. The proportion of participants with skin-to-skin contact (SSC) ≥90 min was the highest in Qinglong County, Guizhou Province (90.0%, 95% CI:85.2%-94.8%), followed by Tongjiang County, Sichuan Province (83.6%, 95% CI:77.7%-89.5%). The highest rate of early breastfeeding initiation was observed in Tongren County, Qinghai Province (99.3%, 95% CI:97.8%-100.0%). The positive experience of SSC for mothers were mainly from the promotion of happiness and early breastfeeding. Applied no medicine to the end of the umbilical cord, neonatal routine eye care, and vitamin K 1 administration were successfully promoted in the four counties, which gradually became a norm. However, some respondents still had doubts about SSC and applying no medicine to the end of the umbilical cord. Conclusions:Core practices recommended in EEEC were successfully introduced to the project counties despite concerns about certain practices from some medical staff and mothers. Further dissemination and training for EENC were needed to promote the scale-up of EENC in China.
