Objective To explore the effect of the synthetic rehabilitation therapy for the stroke patients with cognitive deficits,and the improvement of the patients'motor function and independent living ability.Methods The synthetic rehabilitation therapy was carried out in 136 stroke patients with cognitive deficits.The synthetic rehabilitation therapy including :acupuncture,hyperbaric oxygen therapy ,cognitive training and physical therapy etc.The patients'cognitive function,motor function and independent living ability were evaluated and analyzed statistically before and after the treatment.Results the patients'cognitive function,motor function and independent living ability are significantly higher after the treatment (P＜0.01).Conduston The synthetic rehabilitation therapy can significantly improve the cognitive function of the patients with cognitive deficits,and it can improve their motor function and independent living ability.

Objective:To analyze the current situation and requirements of education for health technicians in maternal and child health care institutions, and put forward feasible strategies and measures to improve the comprehensive quality and professional level of the talent team of maternal and child health care institutions.Methods:Questionnaire survey was carried out on education needs of health technical staff of 11 maternal and child health care hospitals in 4 provinces (regions), and provincial, municipal and district-level medical institutions. The survey results were recorded by Epidata 3.1. SPSS 22.0 software was used for statistical analysis.Results:A total of 1 678 questionnaires were included in the analysis. A total of 1 313 people received training, accounting for 78.2%. The main reason for not receiving training was that the unit didn't arrange (180 people), accounting for 49.3%(180/365). There were 779 people who had more than 3 days of training, accounting for 59.3%. There were 384 people who were trained in superior general hospitals, accounting for 29.2%, and 268 people were trained in superior maternal and child health institutions, accounting for 20.4%. There were 837 people who learned the content of new professional progress, accounting for 50.8%(837/1 648). According to the interview, there were still some requirements for thematic training, further education, online learning, continuing education and standardized training.Conclusion:Maternal and child health care institutions have accelerated the construction of professional personnel, intensified training, and thoroughly implemented health personnel training programs, established a long-term mechanism, increased funding, improved training content, ensured the quality of training, and made a good job in hierarchical training to meet the learning needs of personnel at all levels. This is of great significance for strengthening the technical personnel of maternal and child health care institutions and improving their service capacity.

Allergic rhinitis(AR)is a type Ⅰ allergic reaction,which mediated by immunoglobulin E immediately when an individual with a special constitution is exposed to a same allergen for second time,whose pathogenesis has not been clarified yet,and closely related to genes,immune cells and cytokines.Pathogenesis of AR become more deeper and more accurate due to rapid develop-ment of molecular biology and second-generation gene sequencing technology.Current studies have found that miR-155 and transcrip-tion factor GATA3 have important regulatory effects on occurrence and development of AR,then affect dominant differentiation of CD4+T lymphocytes and proliferation of ILC2.This article discusses and reviews pathogenesis of AR,which mainly focuses on miR-155/GATA3 pathway and effects of related upstream genes and downstream regulatory substances.

【Objective】 To analyze the demographic characteristics of whole blood donors who responded to blood donation initiatives launched by our blood center, so as to formulate an efficient recruitment strategy and provide scientific reference for solving seasonal, structural and acute blood supply tensions in this region. 【Methods】 Such characteristics as age, gender, household registration, occupation, blood type, education level, number of blood donations, blood donation location and recruitment method of 21 934 whole blood donors who responded to donation appointments issued by our blood center during January 2019 to June 2020 were analyzed, and the corresponding recruitment strategy in this region was established. 【Results】 39.79% of respondents were 36~45 years old, 69.61% were males, 70.49% were non-local permanent residents, and 62.96% were with education background from junior high school to high school. Workers accounted for 36.57%, 400 mL-donation accounted for 56.87%, the percentage of blood type O reached 42.18%, and blood donors with 2~5 donations accounted for 70.27%. The proportion of blood donors from Songshan Lake area(23.46%) ranked the highest, and that from Shuixiang area the lowest (3.26%). 76.42% of donation recruitment were issued via SMS. 【Conclusion】 Blood donors 36~45 years old, with 2~5 donations, donated 400 mL blood, non-local registered male, ordinary employees with the education level of junior high school, technical secondary school or high school should firstly be considered. The targeted areas are the Songshan Lake area, the main urban area coastal areas and southeastern Dongguan near Shenzhen.The corresponding recruitment strategies should be adjusted based on needs and emergency level.

【Objective】 To explore the effects of periodontitis on the brains of Alzheimer’s disease (AD) mice and the effects of N-acetyl-L-cysteine (NAC) on the periodontium and the brain of AD mice with experimental chronic periodontitis (CP). 【Methods】 Ten wild-type C57 mice were in the blank control group (Group C57), and another 40 3-month-old APP/PS1 transgenic mice were randomly divided into four groups: AD+CP group, AD+CP+NAC group, AD+NAC group, and AD group. The periodontitis model was established in mice in AD+CP group and AD+CP+NAC group by silk ligation. At the same time, mice in AD+CP+NAC group and AD+NAC group were injected with NAC (200 mg/kg). The height of alveolar bone loss was detected after 3 weeks, and the cell morphology of the hippocampus was observed. We determined the expression levels of NLRP3 inflammasome and amyloid-β (Aβ) in the hippocampus as well as the expression levels of interleukin (IL)-1β and IL-18 in the hippocampus and gums by ELISA. 【Results】 Compared with AD group, the height of alveolar bone loss in AD+CP group was higher (P<0.05), and the expression levels of IL-18 in the gum and IL-1β and NLRP3 in the hippocampus were increased significantly (P<0.05). In addition, compared with AD+CP group, the height of alveolar bone loss in AD+CP+NAC group was reduced significantly (P<0.05), the expression levels of IL-1β and IL-18 in the gum were reduced significantly (P<0.05) as well as the expression levels of IL-1β and Aβ in the hippocampus were reduced significantly (P<0.05). Compared with C57 group, the neurons in the hippocampus of AD+CP group were more loose and disordered, and the activation of microglia was increased, while the disarrangement of cells in AD+CP+NAC group was less than that in AD+CP group. 【Conclusion】 Periodontitis can aggravate brain inflammation in AD mice. NAC can effectively reduce alveolar bone resorption in AD mice caused by periodontitis as well as reduce the levels of inflammatory factors in the gum and hippocampus. NAC can effectively reduce the alveolar bone absorption of AD mice caused by periodontitis, reduce the level of inflammatory factors in the gingiva and hippocampus, and reduce the damage of nerve cells in the hippocampus.
