RESUMO
Objective@#To investigate the health of deciduous teeth and the effect of deciduous teeth caries on the nutritional status of Tibetan children in kindergartens in Zhag-yab of Tibet, so as to provide a reference for the prevention and treatment of dental caries in local children.@*Methods@#A cross sectional survey was conducted among all Tibetan children aged 3 to 7 years in kindergartens from 13 districts in Zhag yab of Tibet, a total of 1 263 eligible children were included. Oral examination, height, weight measurement and hemoglobin test were performed. The health status of children was evaluated according to WHO diagnostic criteria of dental caries rate, average of decayed missing filled tooth(DMFT), malnutrition and anemia, and the correlation between deciduous teeth caries and nutritional status of children were analyzed.@*Results@#The overall deciduous teeth caries prevalence rate of Tibetan children in Zhag yab kindergarten was 62.6%, and the mean dmft was (4.0±4.6). Aged 3, 4, 5, 6, 7-year-old children s deciduous teeth caries rate were 31.1%, 55.3%, 63.8%, 70.9%, 76.6%, respectively, mean dmft were (1.1±2.0) (2.9±3.4) ( 3.5± 3.3) (5.4±5.4) (5.9±6.6) respectively. The prevalence of deciduous teeth caries and mean dmft increased with age, and the differences among age groups were statistically significant ( χ 2/F=72.17, 33.47, P <0.05). The overall detection rate of malnutrition( 25.4% ), stunting(12.3%), underweight(12.6%), wasting(10.9%) and anemia(29.6%) in caries children were higher than those in children without caries(19.5%, 8.1%, 6.1%, 6.6%, 15.5%), the differences were statistically significant ( χ 2=5.81, 5.49, 13.61 , 6.52, 32.02, P <0.05). Caries children s overweight rate (3.7%) was higher than that of children without caries (3.4%), obesity rate ( 1.3% ) was lower than that of children without caries(1.9%), there was no statistically significant difference ( χ 2=0.07, 0.82, P >0.05).@*Conclusion@#The problem of deciduous teeth caries in kindergartens in Zhag yab is serious, and it is closely related to the occurrence of malnutrition and anemia. The prevention and intervention of dental caries in local children should be strengthened.
RESUMO
Objective:To evaluate the efficacy and safety of traditional Chinese medicine (TCM) in the treatment of post stroke cognitive impairment (PSCI). Method:Seven databases, including CNKI, WanFang, VIP, CBM, PubMed, The Cochrane library and ClinicalTrials.gov, were electronically searched for relevant randomized controlled trials (RCTs) of TCM in the treatment of PSCI. The Cochrane risk of bias assessment tool was used to evaluate the methodological quality of the included studies, descriptive analysis was carried out on the included studies, and the Meta quantitative analysis was carried out with RevMan 5.3 software. Result:A total of 16 RCTs were included with 1 296 participants, and they were assigned to the intervention group (n=649) and the control group (n=647). The results showed that TCM combined with western medicine group and TCM group were better than western medicine group in improving the scores of Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE), Barthel Index (BI), Activity of Daily Living (ADL), Chinese stroke scale (CSS) and National Institutes of Health stroke scale (NIHSS) of PSCI patients, and no serious adverse events were observed. Conclusion:TCM has potential advantages in improving the cognitive function of patients with PSCI, and it also has certain efficacy in improving the daily living ability and neurological impairment symptoms, and no serious adverse events have been observed. Due to the low quality of methodology included in the studies, in order to provide reliable basis for clinical decision-making, high-quality of RCTs are still needed to study the efficacy and safety of TCM for PSCI.
