ABSTRACT
Objective To construct and apply a comprehensive information platform for the prevention and control of birth defects based on three-level prevention and control in the birth-age population of Yueyang City, aiming to improve the effectiveness of intervention and reduce the impact of birth defects on the fetus. Methods A retrospective analysis was used to study the married population of childbearing age in Yueyang from January 2017 to December 2019, all of whom were included in the comprehensive information platform for the prevention and control of birth defects based on the three-tier prevention and control. Observed indicators include birth defects I, II and III prevention and control and intervention effectiveness. Results (1) Effectiveness of prevention and control at the first level in each year: After continuous intervention, the education rate, marriage test rate and folic acid distribution in Yueyang city increased year by year, while the incidence of birth defects decreased year by year (P<0.05). (2) Effect of secondary prevention and control in each year: After continuous intervention, the serum screening rate, ultrasound diagnosis rate and amniotic fluid culture rate in Yueyang city increased year by year, while the birth defect rate decreased year by year (P<0.05). (3) Effectiveness of three levels of prevention and control in each year: After continuous intervention, the screening rate of newborns in Yueyang city increased year by year (P<0.05); and the disability rate of CH and PKU was 0% in three years. Conclusions The adoption of a three-level comprehensive prevention and control information platform in the prevention and control of birth defects has the advantages of safe, efficient and stable application, which is conducive to promoting the active conduct of prenatal examinations by pregnant women, enhancing the effectiveness of health education and improving the quality of health care during pregnancy, thereby effectively reducing the incidence, birth and disability rates of children with birth defects and achieving satisfactory graded application results. Accordingly, it is recommended that priority be given to the selection of a three-tier integrated information platform for prevention and control, depending on the actual situation.
ABSTRACT
As a commonly used traditional Chinese medicine,Stellaria dichotoma var. lanceolata has a medicinal history of several hundred years, and been included in the Pharmacopoeia of the People's Republic of China. With a sweet fact and mild war nature, it enters liver and stomach meridians. With effects in clearing deficient heat and eliminating fever in infantile malnu, it has been used to treat such diseases as Yin deficiency fever, consumptive fever due to Yin deficiency and infantile chancre fever, and taken as the raw materials of Wuji Baifeng Wan and other traditional Chinese medicine preparations. In recent years,there have been increasing demands for S. dichotoma var. lanceolata from people. However, its wild resources have been over-excavated for a long time,leading to a serious shortage of wild strains. Furthermore, the quality of artificial S. dichotoma var. lanceolata medicine is far different from that of wild cultivars. Meanwhile,pesticide residues and excessive metal standards due to the irrational use of pesticides and chemical fertilizers in the production process, as well as the large number of counterfeits in the market seriously impact the quality,efficacy and drug safety of S. dichotoma var. lanceolata medicine. Therefore, the non-polluted production technology of S. dichotoma var. lanceolata is of great significance. The non-polluted production technology would be an effective mode for promoting the sound development of S. dichotoma var. lanceolata industry in the future and the key to solve the issues. This article summarizes the environment of suitable production area,plantation method, comprehensive soil improvement, field management and rational fertilization technology. It also proposes that the prevention and control of pollution-free safflower pests and diseases should follow the principle of giving priority to comprehensive prevention. The pollution-free and technical regulation system of S.dichotoma var. lanceolata cultivars is built to produce excellent,high-quality and non-polluted production with low content of pesticide residues and heavy metals,and promote the healthy and sustainable development of the global S.dichotoma var. lanceolata industry.
