Objective: To study the influence of personality on the occurrence of dental trauma of school-aged children. Methods:The school-aged children with dental trauma who came to visit our department were randomly recruited. The Eysenck Personality Scale was used to test the subjects who met the inclusion criteria. Results: 306 children were included in the study. There was a statistically significant association between personality type and the number of traumatic teeth (P ＜ 0. 05) and the number of traumatic teeth in children with extroversion was higher than that of children with neutrality or introversion (P ＜ 0. 05) . Conclusion: Extroverted personality is a significant correlation factor affecting the severity of dental trauma in children, and it is of great significance to provide scientific guidance and warning for them to prevent tooth trauma.

OBJECTIVETo evaluate the efficacy and safety of 4 treatment options for HBeAg-positive chronic hepatitis B (CHB) patients following a suboptimal response to 24-week interferon monotherapy.

METHODSThe data of 193 HBeAg-positive CHB patients with suboptimal response to 24-week interferon monotherapy were collected from Nanfang Hospital between September, 2010 and January, 2013. According to the subsequent treatments, the patients were divided into group A with additional entecavir or adefovir, group B with further interferon monotherapy, group C with conversion to NAs therapy, and group D with direct therapy withdrawal, and the biochemical and virological results at weeks 24, 48 and 72 were analyzed in the 4 groups.

RESULTSAt week 48, the HBV DNA negative rates and serum alanine aminotransferase (ALT) normalization rates were both significantly higher in group A and C than in group B (P<0.05); in group A, ETV therapy subgroup had a significantly higher HBV DNA negative rate than ADV therapy subgroup at week 48 (90.3% vs 59.5%, Χ=8.255, P=0.004). At week 72, 39.7%(27/68) of the patients in group A achieved HBeAg seroconversion, a rate significantly higher than those in groups B (Χ=4.238, P=0.040) and C (Χ=7.681, P=0.006); the HBV DNA negative rate and ALT normalization rate in group A were 85.3%(58/68) and 86.8%(59/68), respectively, both significantly higher than those in group B (Χ=23.018, P<0.001; Χ=5.987, P=0.014) but comparable to those in group C (P>0.05). In the two subgroups in group A, the HBV DNA negative rate and HBeAg seroconversion rate were both significantly higher in ETV subgroup (Χ=9.823, P=0.002; Χ=5.450, P=0.020). In group D, all the patients remained HBeAg-positive with abnormal ALT levels and high level of HBV DNA.

CONCLUSIONFor HBeAg-positive CHB patients with suboptimal response to 24-week interferon monotherapy, combined treatment with NAs (especially ETV) and extension of the treatment course can significantly improve the HBeAg seroconversion rates, HBV DNA negative rates, and ALT normalization rates.

Objective To investigate the distribution of anxiety and depression disorders in patients of carotid artery stenosis (CAS),and the relationship between symptoms of cerebral infarction and the severity of anxiety and depression.Methods We used Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale(SDS) created by William W.K.Zung to evaluate the anxiety and depression disorders associated with CAS in 93 patients hospitalized at the Department of Vascular Surgery,and 146 hospitalized varicose veins patients as acontrols.Results The scales of CAS are significantly higher than the control group(SAS:32 ± 8 vs 29 ± 7,P ＜ 0.001 ; SDS:42 ± 14 vs 35 ± 11,P ＜ 0.001),within-group analysis of CAS shows that there is no statistical difference between symptomatic group and non-symptomatic group (SAS:32 ±8 vs 32 ± 7,P =0.780; SDS:41 ± 14 vs 42 ± 14,P =0.830),or between infarction group and non-infaction group (SAS:31 ± 8 vs 33 ± 8,P =0.147; SDS:39 ± 14 vs 43 ± 13,P =0.241).Conclusions CAS can cause anxiety and depression disorders,and the disorders are not related to symptoms of cerebral ischemia and cerebral infarction.

Objective To investigate the level of chemotactic factors(CXCL5 and CXCL8)in hepatic fibrosis and cirrhosis tissue.Methods Hepatic tissues were obtained from 9 patients with hepatic hemangioma (hepatic hemangioma group),10 patients with liver fibrosis(liver fibrosis group)and 11 patients with liver cirrhosis(1iver cirrhosis group)at Nanfang Hospital from May 2008 to May 2009.The contents of CXCL5 and CXCL8 in hepatic tissue were assayed by ELISA.All data were analyzed by one-way ANOVA,Pearson rank correlation or Spearman correlation.Results The contents of CXCL5 and CXCL8 were(0.8±0.7)ng/g and(6.2±3.7)ng/g in hepatic hemangioma group,(2.0±2.0)ng/g and(11.6±3.5)ng/g in liver fibrosis group and (17.1±4.8)ng/g and(12.3±3.9)ng/g in liver cirrhosis group,with significant difference among the 3 groups (F=60.050,7.690,P＜0.05).The expression of CXCL5 was correlated with the content of alanine aminotransferase(ALT),aspartate aminotransferase(AST)and prothrombin time(PT)(r=0.502,0.468,0.523,P＜0.05):the expression of CXCL8 was correlated with the content of ALT,AST.total bilirubin and PT(r=0.477,0.504,0.537,0.431,P＜0.05).Conclusions With the aggravation of hepatic fibrosis,the contents of CXCL5 and CXCL8 are increased with different patterns.The changes of CXCL5 and CXCL8 are related with the injury of liver,but the changes of CXCL5 and CXCL8 do not correspond with the degree of the injury of liver.
