The level of CD4~+ CD25~+ regulatory T cells was assayed in the peripheral blood from the patients with Graves' disease (GD) by floweytometry.CD4~+ CD25~+ regulatory T cells as a kind of non-specific immune cells appear to have no relationship with thyroid function,however,their lowered number in early GD patients suggests that they seem to play an essential role in the pathogenesis of GD.

Objective:To observe the acoustic characteristics of glottal stops produced by patients with cleft palate.Methods:Twenty boys with cleft palate who were judged to be glottal-stop-producers and 20 normal peers were included. In their own way, all the children were asked to produce following sounds: /iu/ /pai/ /t′u/, /s/ /k′/ /p′u/ /t′u/, /tA/ /ku/ and /i/ /k′u/ /ti/ /suan/. Then the speech spectroanalysis and the comparison were performed by one investigator.Results:The acoustic characteristics of glottal stops changed a lot when they substitute or accompany with different oral stops, which included the emergence of spikes, changes of voice onset time, the formant transitions and spetroanalysis of spikes. Conclusion:The acoustic changes of glottal stops are complicated. Every single aspects of acoustic analysis should be considered in the identification of the acoustic characteristics.

OBJECTIVETo investigate the correlation between articulation, velopharyngeal function, and surgical age by comparing the changes in articulation after velopharyngeal closure is performed. This study is also conducted to investigate the influencing factors of omission change between pre- and post-operation.

METHODSA total of 48 patients, including 18 males and 30 females, mean age (13.3 ± 5.8) years, with non-syndromic cleft lips and palates were selected from January 2011 to December 2011. Their speech data and articulation between pre- and post-operation were retrospectively analyzed using non-parametric tests. Correlation study was performed to analyze the influencing factors of the changes in articulation. P < 0.05 was considered statistically significant.

RESULTSThe difference in articulation after velopharyngeal closure occurred was significant (Z = -3.796, P = 0.000). A negative correlation between the ratio of post-operative normal articulation and surgical age (R = -0.487, P = 0.000) was observed. The change in omission was positively correlated with surgical age (R = 0.589, P = 0.000) and gender (R = 0.404, P = 0.047). By comparison, the change in omission was negatively correlated with follow-up time (R = -0.235, P = 0.040).

CONCLUSIONArticulation and intelligibility are significantly improved after velopharyngeal closure is performed. These parameters are negatively correlated with surgical age to some extent. In addition, the change in omission is positively correlated with surgical age and gender, whereas the change in omission is negatively correlated with follow-up time.

OBJECTIVETo determine the factors affecting post-operative velopharyngeal function of cleft palate patients aged over two years old.

METHODSThe data on 245 patients, including first visit case records and those in the database, were searched and recorded. Post-operative velopharyngeal function and clinical features, such as cleft ratio, adequate ratio, diagnosis, operative age and method, were analyzed retrospectively.

RESULTSCleft ratio and adequate ratio in the velopharyngeal competence (VPC) group were not statistically different from those in the velopharyngeal incompetence (VPI) group. The difference in VPC rate in different age groups and diagnosis was not significant. The post-operative VPC rates under different methods were significantly different.

CONCLUSIONThe current therapeutic schedule for patients younger than two years old is inappropriate for patients older than two years old. Cleft ratio is not the main factor affecting postoperative velopharygeal function. Sommerlad-Levator Veli Palatini reconstructional operation combined with sphincter pharyngoplasty can obviously improve the velopharyngeal function of patients aged 2 years old and up. This method should be applied in primary palatoplasty.

Objective: To investigate the prevalence of hypertension among primary and middle school students living in Suzhou City, Jiangsu Province, so as to provide insights into comprehensive hypertension control among children and adolescents. Methods: Primary and middle school students at ages of 7 to 17 years were recruited for a questionnaire survey in Suzhou City using the stratified cluster random sampling method from September to December, 2020, and the height and body weight were measured. Blood pressure was measured at three separate clinic visits according to the national criteria Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years ( WS/T 610-2018 ), and the detection of elevated blood pressure was estimated at three separate visits. In addition, factors affecting elevated blood pressure were identified. Results: A total of 3 713 students were enrolled, including 1 924 boys ( 51.82% ) and 1 789 girls ( 48.18% ). The detection of elevated blood pressure was 13.63%, 5.36%, and 3.37% at three separate visits, respectively, and the prevalence of hypertension ( elevated blood pressure at all three visits ) was 3.37%. The detection rates of elevated blood pressure were all higher at three visits ( 16.90%, 8.40%, and 5.26% ) among students at ages of 12 to 17 years than among students at ages of 7 to 11 years ( 9.65%, 1.67%, and 1.07%, P<0.05 ). The detection of elevated blood pressure was significantly higher in boys ( 15.23% ) than in girls (11.91%) at the first visit ( P<0.05 ), while no significant differences were seen at the second or third visit ( P>0.05 ). In addition, higher detection rates of elevated blood pressure were seen in obese ( 27.62%, 11.51%, and 7.06% ) and overweight students ( 17.45%, 6.95%, and 4.85% ) than in students with normal weight ( 9.44%, 3.54%, and 2.15% ) at all three visits, and greater detection rates of elevated blood pressure were found in obese students than in overweight students at the first and second visits ( P<0.017 ). Conclusions The prevalence of hypertension was 3.37% based on three separate visits among primary and middle school students in Suzhou City. Measurement of blood pressure at three separate visits within different days is effective to reduce the false positive rate of hypertension and decrease misdiagnosis among children and adolescents.
