Objective To study the changes of plasma endothelial microparticles (EMP) in children with Kawasaki disease (KD) and its relation to coronary artery lesions (CAL).Methods The participants in this study were 30 children with KD (24 children with typical KD and 6 cases with incomplete KD).All KD patients met the diagnostic criteria established by the Japanese Kawasaki Disease Research Committee.According to the course of KD,3 phases were divided:the acute phase,the subacute phase and the convalescent phase.We evaluated the presence of CAL using two-dimensional echocardiographic examination,and then the KD children were divided into two groups,including 24 children without CAL and 6 children with CAL.Ten children with fever and rash and 10 healthy children were studied as control.The levels of CD31+/CD42b- EMP were measured by flow cytometry.Results The level of EMP was significantly higher in the acute phase [ (8.18 ± 2.29) ％ ] than those either in the convalescent phase [ (2.77 ± 0.85 ) ％ ] of KD or the healthy children [ ( 1.34 ± 0.38 ) ％ ] (P ＜ 0.01 ).The level of EMP was also significantly higher in the subacute phase [ (5.93 ± 1.05 )％ ] than those either in the convalescent phase of KD or the healthy children (P ＜0.01 ).The level of EMP was higher in the children with fever [ (3.66 ± 1.16) ％ ] than that in the healthy children ( P ＜ 0.05 ).Furthermore,the level of EMP during the acute phase was also higher in KD patients with CAL than in those without CAL(P ＜0.01 ).Conclusion The measurement of EMP may be useful for the early diagnosis of KD and the identification of CAL.

Objective To investigate the impact of obstructive sleep apnea hypopnea syndrome (OSAHS) on development of nonalcoholic fatty liver disease (NAFLD) in the non-obese elderly.Methods A total of 91 non-obese elderly patients were divided into 3 groups,29 cases with mild to moderate SAHS (mild-to-moderate OSAHS group),31 cases with severe OSAHS (severe OSAHS group),30 cases without OSAHS and matched with age,sex and BMI (control group).The changes in NAFLD severity index including serum liver enzyme levels,Type Ⅲ procollagen peptide (PⅢ P)and liver/spleen CT ratio were observed,and the influence factors for the changes were analyzed.Results Serum alanine aminotransferase (ALT),aspartate aminotransferase (AST)ALT/AST ratio and serum PⅢ P levels were significantly higher in severe OSAHS group than in mild-to-moderate OSAHS and the control group(F=25.71,15.15,18.64,respectively,all P＜0.01).There was no significant differences in serum liver enzyme ALT,AST and P Ⅲ P levels between mild-to-moderate OSAHS and the control groups(all P＞0.05),and the ALT/AST ratio was significantly higher in mild-to-moderate OSAHS group than in the control group(P＜0.01).The Liver/spleen CT ratio was significantly lower in OSAHS groups than in control group,while the ratio was lower in severe OSAHS group than in mild-to-moderate OSAHS group(all P＜0.01 or 0.001).Serum PⅢ P level was significantly higher in OSAHS groups than in control group(F=31.46,P＜0.01),while PlⅢ P levels were not significantly different between the mild-to-moderate OSAHS group and the control group(P ＞ 0.05).The correlation analysis showed that the liver/spleen CT ratio in OSAHS group was negatively correlated with AHI(r=-0.785,P＜0.001),but was positively correlated with the lowest oxygen saturation(r=0.517,P=0.001).The ALT/AST ratio and serum P Ⅲ P level in OSAHS patients were positively correlated with AHI (r=0.463,0.770,both P＜0.001),but were negatively correlated with the lowest oxygen saturation (r=-0.395,-0.514,P＜0.01 or 0.001).The multiple regression analysis showed that AHI was the only variable that affected liver/spleen CT ratio and serum P Ⅲ P level in OSAHS patients.Conclusions OSAHS patients in the non-obese elderly are always complicated with NAFLD,characterized by abnormal liver enzymes,hepatic steatosis and fibrosis.The severity of lesion is increased with the deterioration of OSAHS.AHI may play an important role in the development of NAFLD in the non-obese elderly with OSAHS.

BACKGROUND:Individuals with different vertical facial types have different chin morphologies. For the individuals with different vertical facial types, what is the most beautiful chin morphology?
OBJECTIVE:To evaluate the effects of vertical facial types and chin morphology on facial profile attractiveness.
METHODS:Three beautiful females were selected, including one with high mandibular angle, one with average angle and one with low angle. Their facial profile photographs were taken. A series of new pictures were generated by the smal scale (2 mm per unit) modification of soft tissue chin in the sagittal direction and vertical direction. Raters consisting of 17 orthodontists and 35 laypersons were selected for aesthetic ratings, in order to evaluate the facial profile attractiveness of the individuals with different vertical facial types.
RESULTS AND CONCLUSION:There was no esthetic difference of vertical change in female with high angle;while slightly protrude chin was perceived to be more beautiful than retruded chin. For the female with average angle, lower chin was more attractive than higher chin;slightly protruded chin was beautiful than excessive protruded chin and retruded chin. For the individual with low angle, higher chin was preferred by raters;slightly protruded chin was more beautiful than excessive protruded chin and retruded chin.The results indicate that the effects of vertical facial types and chin morphology to facial profile attractiveness are different. In clinical orthodontic, vertical facial types should be taking into consideration to change the chin morphology of the patents, in order to obtain better profile attractiveness.

BACKGROUND:Preliminary studies of our research group have confirmed that bone morphogenetic protein-4 can stimulate the development of mandible in the growth period, but whether bone morphogenetic protein-4 can interact with bone morphogenetic protein-2 to promote the growth of mandible has not been reported. OBJECTIVE:To detect the expression of bone morphogenetic protein-2 and bone morphogenetic protein-4 in skeletal class II malocclusion during growth peak, and to explore the relationship of the expression of bone morphogenetic protein-2 and bone morphogenetic protein-4 with mandibular growth. METHODS: Patients with skeletal class I malocclusion in growth peak served as group I, and those with skeletal class II malocclusion in growth peak characterized as mandibular retrognathia acted as group II. There were 18 cases in each group. Expression of bone morphogenetic protein-2 and bone morphogenetic protein-4 in serum was detected by real-time fluorescent quantitative PCR. RESULTS AND CONCLUSION:The mRNA expression of bone morphogenetic protein-2 and bone morphogenetic protein-4 in the group II was significantly lower than that in the group I (P < 0.05). In the group II, there was a significant correlation between the expression of bone morphogenetic protein-2 and bone morphogenetic protein-4. These experimental findings confirm that the reduced expression of bone morphogenetic protein-2 and bone morphogenetic protein-4 in skeletal class II malocclusion during growth peak has a certain relationship with mandibular deficiency, and moreover, bone morphogenetic protein-2 interacts with bone morphogenetic protein-4 to promote the growth of mandible.

To set up a new method of detecting bacterial number in situ,NADH fluorescence method based on the fluorescent characteristic of NADH was used.When the concentration of NADH ranged from 10 nmol/L to 0.2 mmol/L,its concentration had a good line relationship to the fluorescence intensity(R2= 0.9905).Separating bacterial cells by centrifugation and extracting NADH with hot Tris-HCl buffer,the re-sult of bacterial count detected with NADH standard plot was 1?104 CFU/mL in an hour.In summary,NADH fluorescence method is rapid,sensitive,simple and reliable to detect total bacterial number.There-fore,the method can be widely applied in the field of food sanitation and safety,environment detection and so on.

Objective To explore the relationship between job burnout feeling and sleep quality in psychiatric female medical staff.Methods 100 female medical staff were randomly selected from two mental hospitals in Wenzhou,and the Pittsburgh sleep quality index was used to evaluate and Maslach burnout inventory;and the relation-ship between sleep quality and job burnout was analyzed.Results Female psychiatric and medical personnel to the personality dimension score was (10.84 ±4.75)points,which was higher than Maslach norm (7.12 ±5.22)points;emotion exhaustion scores of (14.44 ±6.38)points,low achievement sense score of (15.07 ±6.89)points,below the Maslach often die emotion exhaustion scores of (22.19 ±9.53)points and low achievement sense scores (36.54 ± 7.34)points.The differences were statistically significant (t =-12.15,7.84,-31.15,all P <0.01).Job burnout and there were significant correlations between sleep quality and the emotional exhaustion and personification and PQSI seven dimensions and the total score was a positive correlation,low sense of achievement and PQSI total score and negatively correlated with seven dimensions.Conclusion Wenzhou psychiatric female medical staff burnout is significantly higher than the general population,there is a correlation between staff burnout and sleep quality,and the more serious burnout,poorer quality of sleep.Improving the quality of sleep of medical staff is one of the ways to relieve job burnout.
