Analysis on the Application Effect of Abdominal Acupoint Massage on Feeding Intolerance in Premature Infants.

Objective: Breast milk is the best food for newly born infants because it is more digestible and can relieve infants' gastrointestinal burdens. The purpose of this study was to investigate the application effect of abdominal acupoint massage on feeding intolerance in premature infants. Methods: A total of 50 premature infants with feeding intolerance admitted to our hospital from January 2018 to October 2019 were selected and randomly divided into the control group (n = 25) and the experimental group (n = 25). Among them, the premature infants in the control group received routine therapy, while based on the treatment in the control group, the premature infants in the experimental group were treated with abdominal acupoint massage. After that, the incidence of feeding intolerance, MNA nutritional status score, body mass, development state, length of hospital stay, and response rate were all compared between the two groups to analyze the application effect of abdominal acupoint massage on feeding intolerance in premature infants. Results: The incidence of feeding intolerance of the premature infants in the experimental group was significantly lower than that in the control group, with statistically significant differences (P < 0.05); the MNA nutritional status scores of the premature infants in the experimental group were significantly higher than those in the control group, with statistically significant differences (P < 0.05); the body mass and development state of the premature infants in the experimental group were significantly better than those in the control group, with statistically significant differences (P < 0.05); the length of hospital stay of the premature infants in the experimental group was significantly shorter than that in the control group, with statistically significant differences (P < 0.05); the response rate in the experimental group was significantly higher than that in the control group, with statistically significant differences (P < 0.05). Conclusions: Abdominal acupoint massage therapy can significantly reduce the incidence of feeding intolerance, shorten the length of hospital stay, and improve nutritional status, development state, and response rate in premature infants, with obvious therapeutic effect, which is worthy of application and promotion in clinical practice.

Application Effect of Acupoint Massage on Zusanli on Premature Infants with Feeding Intolerance and Their Clinical Symptoms.

FI is mainly caused by functional disturbance in premature infants, which greatly poses a threat to their growth and development, so a large number of studies on the clinical features of FI should be conducted to provide theoretical support for treatment. The purpose of the study was to investigate the therapeutic effect of acupoint massage on Zusanli on premature infants with feeding intolerance (FI) and their clinical symptoms. A total of 60 premature infants with FI admitted to our hospital over the past two years were selected as the FI group, and another 60 premature infants without FI were selected as the control group. The birthweight and gestational age of the premature infants in the FI group were significantly lower than those in the control group (P < 0.001), whereas there were no significant differences in general information of the premature infants between the two groups (P > 0.05). Vomiting, abdominal distension, and gastric retention are the main clinical symptoms of premature infants with FI, and acupoint massage on Zusanli combined with routine treatment can effectively improve digestive function, relieve clinical symptoms, and shorten treatment time of premature infants with FI, which is worthy of application and promotion in clinical practice.

Prevalence of and factors associated with myopia in primary school students in the Chaoyang District of Beijing, China.

PURPOSE: To determine the prevalence of and risk factors for myopia in primary school children in Chaoyang District, Beijing. METHODS: This cross-sectional prevalence survey was conducted in September to October 2011 in 4 schools randomly chosen from among the 126 primary schools in Chaoyang District. Students were assessed with autorefractometry under cycloplegia and checked with retinoscopy for accuracy. Questionnaires were completed by the students' parents. RESULTS: Myopia was present in 36.7 ± 0.7% of 4249 students aged 5-14 years old. The prevalence of myopia in girls (38.6 ± 1.1%) was significantly higher than in boys (35.0 ± 1.0 %) (p = 0.015) and increased with age (p < 0.001), with the highest prevalence observed in children aged ≥11 years (67.5 ± 1.8%). After adjustment, having a myopic parent (aOR 3.10; 95% CI 2.49-3.86), incorrect reading posture (aOR 2.09; 95% CI 1.75-2.50), reading a book at a distance of <20 cm (aOR 1.60; 95% CI 1.16-2.21), studying at home for >3 h daily (aOR 1.50; 95% CI 1.12-2.01), studying for >1 h continuously (aOR 1.21; 95% CI 1.02-1.45), and reading extracurricular books that utilize a font larger than that used in textbooks (aOR 0.74; 95% CI 0.59-0.94) were all significantly associated with myopia. CONCLUSIONS: The prevalence of myopia among primary school children in Beijing increased with age, and was significantly higher in girls ≥10 years old. Myopia was significantly associated with parental myopia, reading posture, distance between the eyes and the book being read, font size used in extracurricular reading material, time spent studying at home, and the duration of continuous study time.

Study on the third and second-order nonlinear optical properties of GeS(2)-Ga(2)S3-AgCl chalcohalide glasses.

Third-order optical nonlinearities, chi((3)) of GeS(2)-Ga(2)S(3)-AgCl chalcohalide glasses have been studied systematically utilizing the femtosecond time-resolved optical Kerr effect (OKE) technique at 820nm, showing that the value of chi((3)) enhances with increasing atomic ratio of (S+Cl/2)/(Ge+Ga). From the compositional dependence of glass structure by Raman spectra, a strong dependence of chi;(3) upon glass structure has been found, i.e. compared with [Cl(x)S(3-x)Ge(Ga)-Ge(Ga)S(3-x)Cl(x)] ethane-like s.u. as the structural defectiveness, [Ge(Ga)S(4-x)Cl(x)] mixed tetrahedra make greater contribution to the enhancement of chi((3)). The maximum chi(3) among the present glasses is as large as 5.26x10(-13)esu (A1 (80GeS(2)-10Ga(2)S(3-) 10AgCl)), and the nonlinear refractive index (n2) of A1 glass is also up to 4.60x10(-15) cm(2)/W. In addition, using Maker fringe technique, SHG was observed in the representative A1 glass poled by electron beam (25 kV, 25 nA, 15 min), and the second-order optical nonlinear susceptibility is estimated to be greater than 6.1 pm/V. There was no evident structural change detected in the as-prepared and after irradiated A1 glass by the Raman spectra, and maybe only electronic transition and distortion of electron cloud occurred in the glasses. The large third/second-order optical nonlinearities have made these GeS(2)-Ga(2)S(3)-AgCl chalcohalide glasses as promising materials applied in photoelectric fields.
