Résumé
This paper reported a pair of twin babies who were diagnosed as monochorionic (MC) twins (MC) in the first-trimester ultrasound scan after in vitro fertilization.Fluorescence in situ hybridization and chromosomal karyotype analysis of amniotic fluid that was randomly collected from one of the twins were performed in the second trimester,but no abnormality was detected.Chromosome karyotype analysis of peripheral blood of the twins at the age of two days and three years showed that both were chi 47,XY,+21/46,XX.And the single nucleotide polymorphism microarray analysis of oral mucosa cells of the twins at three years old showed that the boy was 47,XY,+21 and the girl was 46,XX.Therefore,we confirmed that they are MC dizygotic twins presenting with blood chimerism but no tissue chimerism.Simply the boy presented with facial features of Down syndrome.
Résumé
Objective To investigate the influence of cognitive training on patients with Alzheimer's disease. Methods 30 patients received cognitive function training based upon drug treat-ment. Patients were assessed with mini- mental state examination (MMSE) and functional independence measure(FIM) before and after treatment, the results went through t test. Results After training, cog-nitive function and self- care ability after treatment greatly alleviated compared with those before train-ing. Conclusions Cognitive training can improve cognitive function and self- care ability of patients with Alzheimer's disease and facilitate their life quality.
Résumé
Objective To compare the influence of the continuous airway humidification with microp-ump and the discontinuous dripping technique on patients. Methods Randomized grouping method was adopted, 25 cases with tracheotomy in the observation group used continuous airway humidification with micro-pump, 24 cases in the control group used dripping technique via airway for airway humidification. The two groups were compared retrospectively. Results The oxygen saturation rate in the observation group increased compared with that of the control group, sputum callus formation, irritating cough, airway bleeding and pul-monary infection was significantly lower than those of the control group. Condusious The effect of continu-ous airway humidification with micro- pump is superior to the traditional method of inconsistent endotracheal dripping, the former can also decrease nursing workload of airway humidification.
