ObjectiveTo explore the status of social anxiety and study the relationship between social anxiety and self-consciousness,self-esteem among primary students.MethodsUsing stratified randomization sampling method,568 primary students in grade 4 ～ 6 were investigated with social anxiety scale for children( SASC ),self-consciousness scale for children(PHCSS) and self-esteem scale(SES).Results①The score of SASC in the group of primary students was obviously higher than that of Chinese norm (P＜0.01).②The SASC and negative evaluation scores in the female were higher than the male (P ＜ 0.05 ),the negative evaluation scores in the sixth grade (3.22 ± 2.82) was higher than the fifth grade (2.53 ± 2.76,P ＜ 0.01 ) and fourth grade ( 2.54 ± 2.68,P＜ 0.05 ).The primary students in migrant workers elementary school,the single parent family and the relatively low income family had higher social anxiety scores than others(P＜0.05 ).③The SASC and two major factors were significantly negative correlated with the self-consciousness and each subscale( r =-0.202 ～ -0.511,P ＜ 0.01 ),and positive correlated with the self-esteem( r =0.282,0.270,0.305,P ＜ 0.01 ).④)The anxiety and gregariousness had significant prediction function of 25.5％ on negative evaluation,and 28.2％ on SASC,anxiety,gregariousness,intelligence and school situation had significant prediction function of 20.4％ on social avoidance and distress.ConclusionsPrimary students in grade 4 ～ 6 existed social anxiety.There are significant differences for their level of anxiety in different gender,grade,elementary school,family structure,monthly income.And social anxiety is closely related to self-consciousness and self-esteem.

Objective To explore the association between monoamine oxidase A (MAOA) variable number tandem repeat (VNTR) polymorphism and panic disorder,and then to compare panic disorder(PD) severity patient with different MAOA VNTR genotypes.Methods The structured clinical interview for the diagnostic and statistical manual of mental disorders fourth edition (DSM-Ⅳ) Axis I Disorders (SCID-1) was administered by a trained clinical psychiatrist,135 patients with PD and 195 healthy controls were recruited.MAOA-VNTR polymorphism were measured by fluorescent tags amplification product length polymorphism technology,Chi-square test was used to compare the distribution difference between each genotype and the allele frequency distribution.Results ①Whether male or female,there was no statistically significant difference between case group and healthy control group in the genotype and allele frequencies of MAOA-VN-TR polymorphism (x2=1.574,1.894,3.588;all P＜0.05).② There was no statistically significant difference between genotypes and panic disorder severity in the male with panic disorder ((14.46± 3.53),(14.15 ± 4.02);t=-0.247,P＞0.05).③)However,there was significant difference between genotypes and panic disorder severity in the female with panic disorder((13.15±3.47),(16.57±4.34),(15.27±4.91);F=4.222,P＜ 0.05).MAOA VNTR-L/L carriers experienced more serious panic (16.57 ± 4.34) than the patient with MAOA VNTR-H/H (13.15±3.47) (P＜0.01) by LSD multiple test.Conclusion No association between MAOA-VNTR polymorphism and panic disorder is found in Chinese Han population,but low activity homozygous genotype may be related to the severity of panic disorder in female patient with panic disorder.

Objective To explore the mediating effects of security on the severity of panic disorder and life events.Methods Security Questionnaire(SQ),life event scale(LES)were used to investigate 97 cases of patients with panic disorder and 108 cases of normal control group. The severity of panic disorder was assessed by panic disorder severity scale(PDSS).And the correlation and hierarchical regression analy-sis were used.Results ①The panic disorder patients' positive life stimulation(7.95±6.00)were less than that the normal control group's(18.06± 13.60),negative life stimulation and total life events stimulation ((36.64±29.98),(44.59±31.24))were higher than that of the normal control group(respectively(10.19± 7.89),(28.25±14.51)),the differences were statistically significant(all P<0.05).Panic disorder patients' interpersonal security certainty in control and total score(respectively(18.89 ± 8.66),(17.88 ± 7.58), (36.76±13.47))were lower than that the normal control group(respectively(26.64±9.33),(24.34±8.33), (50.98±15.31)),the differences were statistically significant(all P<0.01).②Severity of panic disorder and positive life events were negatively related to positive events,the total score of security,interpersonal securi-ty,certainty in control(r=-0.262--0.392);severity of panic disorder were positively related to the negative life stimulation and total life event(r=0.346,0.280)(all P<0.01).③Security played a partial mediating role between the negative life events and the severity of panic disorder(beta value decreased from 0.346 to 0.253).Conclusion The patients with panic disorder have more negative life events,lower security.And negative life events and lower security are related to the severity of panic disorder.And security plays a partial mediating effect between the negative life events and the severity of panic disorder.

Objective To understand the serum gonadal hormone level of female patients with panic disorder(PD),and to analyze its relationship with the disease severity.Methods The chemiluminescence method was adopted to detect serum gonadal hormone level in 57 female patients with panic disorder and 74 healthy subjects,the panic disorder severity scale (PDSS),Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD) were simultaneously used to conduct the investigation.Results The serum pituitary prolactin (PRL) level in the female patients with PD had lower level was higher than that in the control group,the difference was statistically significant (P＜0.05);the luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels were lower than those in the control group(P＜0.05).The difference of the serum testosterone,estradiol and progesterone levels between the female patients with panic disorder and control group was not statistically significant (P＞0.05).The correlation analysis found that serum T level in the female patients with PD was negatively correlated with the disease severity of panic disorder,HAMD total score,retardation factor and sleep disorder factor (P＜0.05).Serum LH and FSH were positively correlated with the anxiety somatic factor of HAMA (P＜0.05).Serum FSH level was positively correlated with anxiety somatization and the sleep disorder factor of HAMD (P＜0.05).Conclusion The disorder of gonadal hormone levels may exist in the female patients with PD,and the serum T level is correlated with the PD severity and depressive symptoms.
