Objective:To explore the method of sequential sector scan with 2D ultrasound through oral fissure (SSTOF) and its utilization in the cleft palate screening.Methods:Based on features of oral anatomy and ultrasonic beam, SSTOF was designed to screen cleft palate and the accuracy had been verified using specimens of aborted fetuses. This study recruited 7 154 women with singleton pregnancy who were screened for fetal malformations during 20-28 gestational weeks in the First Affiliated Hospital of Anhui Medical University from May 2020 to October 2020. In medical addition to routine screening, these subjects also underwent SSTOF to further verify its feasibility and imaging performance. Follow-up was performed by telephone and medical record review.Results:Clear images of the upper palate were acquired in five specimens of induced fetuses using SSTOF. Except for 56 cases lost to follow-up, a total of 7 098 fetuses were finally enrolled, of which 6 885 acquired satisfactory images using SSTOF, 213 did not due to inappropriate position, with a success image rate of 97%. SSTOF found cleft palate in 31cases, which were all confirmed after birth or induction, noting an accuracy rate of 100%.Conclusion:Sequential sector scan through oral fissure has a high clinical value on cleft palate screening in the second trimester with advantages of clear image, easy operation, and access to section views.

Objective To discuss the effect of mind map combined with physical care in the prevention and treatment of stroke for elderly patients with hypertensionin community.Methods A total of 100 cases of elderly patients with hypertension from March to September 2015 who met the inclusion criteria were included in the study. According to random numbers generated by the computer, patients were randomly divided into intervention group and control group, 50 cases respectively. The two groups were followed up routinely. Patients in the intervention group were guided by the mind map combined with physical care. The mind map was made and designed to assess the patient's constitution. Individualized health guidance was developed according to the patient's physique identification. The intervention time was 24 weeks. The self-management behavior,systolic blood pressure, diastolic blood pressure, biased syndrome, and stroke morbidity before and after the intervention were compared between the two groups.Results Before the intervention, there were no significant differences in self-management behavior, systolic blood pressure, diastolic blood pressure, biased syndrome and stroke morbidity between the two groups (P>0.05). After the intervention, dietetic adjust and nursing, sports health, emotion transfer, daily life transfer, regularly blood pressure checking in the intervention group were significantly better than those in the control group; and the scores of self-management behavior increased compared with those before the intervention; BMI, systolic blood pressure, diastolic blood pressure, and biased syndrome score were significantly lower than those in the control group and before the intervention; Control rate of blood pressure was 78% in the intervention group, which was significantly higher than that in the control group (46%) (P<0.05). The incidence of stroke was 20% in the intervention group, which was lower than that in the control group (40%), with no statistically significant difference between the two groups (P>0.05). Conclusions Mind map combined with physical care can improve the self-management behavior of patients with hypertension in the community, and reduce diastolic blood pressure, systolic blood pressure and biased syndrome. However, the effect in the prevention of stroke requires further investigations.
