ABSTRACT
Objective:To explore the effect of behavioral training of creative art therapy(CAT) on interpersonal communication in teenagers.Methods:Eighty teenagers were randomly divided into study group( n=40) and control group( n=40).The study group was received the behavioral training of CAT (12 times, each activity lasts for 120 min), and the control group did not take part in the behavioral training of CAT.The two groups were measured with self-esteem scale(SES), shyness scale(SS) and social anxiety scale for children(SASC) before and after behavior training.SPSS 17.0 software was used for statistical analysis, and t-test variance analysis and Mann-Whitney U test were used to compare the differences between groups or within groups. Results:Before and after behavioral training, changes in the SES total score (7.00(5.00, 9.75) vs 1.00(0, 2.00)), the SS total score (7.00(6.00, 12.75) vs 2.00(1.00, 3.00)), the SASC total score (5.00(2.00, 8.75) vs 0(0, 1.00)) and two factor scores (3.00(0.25, 5.00) vs 1.00(0, 1.00), 2.00(1.00, 4.00) vs 0(0, 1.00))in the study group were obviously higher than those in the control group( Z=-7.347, -7.338, -5.841, -4.122 and -5.393, all P<0.05).The score differences of the SASC total score ((7.19±3.82) vs (3.21±3.04)) and two factor scores ((4.00±2.23) vs (1.68±2.05), 3.00 (1.00, 5.00) vs 2.00 (0, 2.00)) of girls were significantly higher than those of boys in the study group ( t=-3.611, -3.398, Z=-2.111, P=0.001, 0.002, 0.035). Conclusion:Behavioral training of CAT can improve teenagers' self-esteem, relieve their shyness and social anxiety, as well as promote their interpersonal communication.
ABSTRACT

ABSTRACT
Objective@#To construct a three-dimensional (3D) finite element model and analyze the biomechanical characteristics during mandibular second molar mesialization using customized lingual appliances and mini-implant.@*Methods@#One adult student volunteer from The First Affiliated Hospital of Zhengzhou University with lower left first molar extraction was selected. After CT scanning, Mimics, Geomagic, ANSYS were employed to develop a 3D finite element model including customized lingual brackets, stainless steel lingual arch wire, buccal buckles, lower dentition, periodontal ligaments and alveolar bone. Four different loading methods (1. the force of 1.470 N loaded at the lingual side only; 2, 3, 4. the forces of 0.490, 0.735 and 0.980 N loaded at both buccal and lingual sides, respectively.) were included. The initial displacements of the lower second molar and stress distribution in the periodontal ligaments were analyzed.@*Results@#More uniform stress distributions in the periodontal membrane of mandibular left second molar were found when the mesial force were loaded at both buccal and lingual sides than the force loaded at lingual side only. More inclination of the second molar was observed when force loaded at both sides than at lingual side only. With the values of the force increased, the mesial inclination potential of the second molar, the initial movement of the second molar and the stress distribution in the periodontal membrane increased. Under the force of 0.735 N at both buccal and lingual sides, mesially inclined initial displacements of the mandibuar second molar were observed and the stress values of von Mises was in the suitable area.@*Conclusions@#Less second molar rotation was found when the force loaded at both buccal and lingual sides than loaded at lingual side only. However, force loaded at both sides would increase the measial inclination potential of the second molar.
ABSTRACT
Objective:To evaluate dental and skeletal changes following slow maxillary expansion with quad helix using Cone-Beam computer tomography (CBCT).Methods:13 patients(5males and 8 females,mean age 14.38 ±2.22 years)requiring maxillary ex-pansion as a part of their comprehensive orthodontic treatment were included.Each patient had CBCT images taken pre-(T1 )and post-(T2)maxillary expansion with quad helix.Changes of the distances between bilateral canines,first premolars,second premo-lars,first molars,the width of basal bone and palatal suture were measured.paired t-test results were analyzed using SPSS 17.0 soft-ware.Results:The distances between the 4 bilateral teeth increased by (2.47 ±1.05)mm,(2.97 ±1.90)mm,(2.79 ±1.21) mm and (3.15 ±1.15)mm,the apical distances decreased by (1.19 ±0.40)mm,(2.12 ±0.68)mm,(2.02 ±0.65)mm and (1.34 ±0.63)mm,respectively.The inclination of the first molars were decreased by (4.45 ±2.86)°and (4.02 ±1.45)°on the left and right side respectively.The width of basal bone and palatal suture increased by (2.37 ±0.96)mm and (1.21 ±0.50)mm respectively,the differences between T1 and T2 were all statistically different(P <0.001).Conclusion:Quad helix expands maxil-lary arch by greater dental changes than by skeletal changes.
ABSTRACT
Objective:To explore the effects of double circumferential fibrotomy(CF)in the improvement of periodontal attachment of the teeth with periodontal disease.Methods:22 migrated incisors of 4 adults were randomly assigned to one-time CF group (T1 )and double CF group(T2)by center line.Periapical intraoral radiographic examination was performed using paralleling technique at pre-and post-leveling-alignment stage of the teeth.Root length,crown-root ratio and the distance of CEJ-AC were measured.The periodontal in-dicators were also recorded during the orthodontic treatment.Data were statistically analysed by comparative t-test.Results:CEJ-AC and crown root ratio reduction was greater in T2 group than those in T1 group(P 0.05).Conclusion:Double circumferential fibrotomy can improve periodontal attachment, reasonable orthodontic force does not lead to remarkable root resorption of the periodontitis inflicted teeth.
ABSTRACT
Objective:To analysis the relationship of cephalometric measurements from intercuspal position(before and after treat-ment)and retruded contact position(before treatment).Methods:18 cases with Class III malocclusion were treated using MBT straight wire appliance technique,all the incisal relationships could be edge-to-edge when the mandible was retruded,X-ray films of intercus-pal position and retruded contact position before treatment and intercuspal position after treatment were taken.The cephalometric meas-urements were statistically analysed by ANOVA.Results:After 25 months treatment the anterior crossbite were corrected in all cases. The molar relationship were class Ⅰ.The measurements of SNB,ANB,MP-FH,MP-SN,U1-SN,L1-MP,Y-axis angle and ANS-Me were significantly changed.Conclusion:After the treatment of Class III malocclusion by MBT straight wire appliance,the sagittal and vertical mandibular location can be between intercuspal position and retruded contact position of pretreatment,and it is more close to the retruded contact position.
ABSTRACT
Objective To produce an experimental information for the safety assessment of Vero cells during subculture. Methods Passage and freeze on Vero cells, and Vero cells in different passages in vitro and in vivo tumorigenicity were tested. The protein expression of different Vero cell passages was analyzed. Results Vero cells passaged to p270 and 14 cell banks were developed and stored for future evaluation. In vitro and in vivo tumorigenicity Lest results of Vero cells in different passages were negative. Conclusion Although the tumorigenicity test results in vitro and in vivo process were negative, the protein expression of more than p200 Vero cells were changed, which produced the experimental reference for the safety evaluation of the process during the Vero cell passage.
ABSTRACT
Objective To investigate the correlation between the severity of coronary artery disease with se-rum bilirubin and left ventricular cardiac function. Methods Two hundred and six patients underwent blood bio-chemical ,color-echocardiography and angiography of coronary artery. The patients were divided into 4 ordinal groups according to the Gensini score indicating the severity of coronary artery disease. Results There were significant differences in total bilirubin(TBIL), left atrial dimension (LAD), left ventricular dimension (LVD) and left ventric-ular ejection fraction (LVEF) between the four groups(P<0.05 or P<0.01). The Spearman correlation coefficent between Gensini's scores and LAD, LVD were 0.280 (P=0.000) and 0.176 (P=0.011), respectively. The Spearman correlation coefficient between Gemini's scores and TBIL, LVEF were -0.541 (P<0.000) and -0.222 (P=0.001), respectively. The multiple linear regression between the Gensini's score and parameters showed that TBIL and LVD were independently correlated with the Gensini scores (P=0.000 and P=0.002, respec-tively). Conclusions TBIL and LVD were independently correlated with Gensini's score. LVEF was negatively cor-related with the severity of coronary disease and is a useful predictor for the severity of coronary atherosclerotic heart disease.
ABSTRACT
Objective To discuss the significance of ventricular rate for patients with persistent atrial fibrillation and to provide theoretical evidence for how to prevent patients of atrial fibrillation from complications such as cerebral embolism and left ventricular dysfunction, and so on. Methods Patients with persistent atrial fibrillation for more than 1 year were divided into cerebral embolism group and non-cerebral embolism group,30 patients per group. The data of patients in both groups were collected and compared, including general clinical characteristics, prothrombin time international standard ratio (PT-INR), the highest, lowest and average ventricular rate detected by Holter monitor system, left atria diameter and left ventricular ejecting fraction measured by echocardiography. Results There was no significant difference between two groups about general clinical characteristics, left atria diameter and PT-INR. The highest,lowest and average ventricular rate were much higher in patients of cerebral embolism group than those in non-cerebral embolism group. However, left ventricular ejecting fraction was much lower in embolism group. Conclusions It is critical to control heart rate for patients of persistent atrial fibrillation to prevent cerebral embolism and left ventricular dysfunction.
ABSTRACT
BACKGROUND: The rehabilitation treatment for acute myocardial infarction has started since 1980' s, but it has not been popularized yet in municipal hospitals due to limited conditions.OBJECTIVE: To probe into the possibility of 3-week rehabilitation intervention in patients with acute myocardial infarction implemented in municipal hospitals.DESIGN: Controlled retrospective analysis was designed.SETTING: Department of Cardiology of YingKou Center Hospital.PARTICIPANTS: Sixty cases of acute myocardial infarction were collected in Department of Cardiology of Center Hospital in Yingkou City in 1996 and they were taken as experimental group. Totally 58 cases of acute myocardial infarction hospitalized in 1986 were taken as the control. In experimental group, 44 cases were males and 16 cases females, aged varied from 34 to 79 years; of which, 45 cases were diagnosed as cardiac dysfunction and cardiac arrhythmia. The situation in the control was near basically to that in experimental group. During the intervention, in experimental group, 10 cases presented chest oppression, 3 cases were afraid to accept the intervention; but by monitoring and explanation, all of those accomplished the experiment.METHODS: In the control, only rational clinical management was given. In experimental group, at the same time of clinical management implemented,the rehabilitation treatment for 3 weeks was carried out for patients with acute myocardial infarction, aiming to earlier movement, earlier getting up, earlier discharge. The rehabilitation procedure stood by gradually increased exercise amount and individualization and it was adjusted according to age, situation of sickness and psychological state, etc. For instance, if the signs of over-endurance presented, the exercise would stop temporarily or the exercise intensity be reduced.MAIN OUTCOME MEASURES: Comparisons of exercise endurance, recovery time of exercise and hospitalizing time in 3 weeks of two groups.RESULTS: The patients in experimental group all accomplished 3-week rehabilitation intervention. In experimental group, the cases, in which, the exercise endurance was up to 5 to 6 equivalents 3 weeks after acute myocardial infarction, were more than the control (78%, 12%, P ＜ 0.05). The cases that were able to go up-down stairs were more than the control(83%, 7%, P＜ 0.05) . The cases hospitalized ＜ 3 weeks were more than the control (78%, 10%, P ＜0.05).CONCLUSION: It is practical and safe to carry on rehabilitation procedure for acute myocardial infarction in municipal hospital. Rehabilitation exercise at the early stage accelerates remarkably the recovery of acute myocardial infarction.
