Objective To explore the physiological and psychosocial risk factors of the patients with somatoform disorders and to provide references for clinical psychological intervention.Methods Totally 60 patients with somatoform disorder and 60 normal controls were tested with biochemical analyzer,electrocardiogram machine,electroencephalogram machine,computed tomographic scanner,general situation questionnaire,minnesota multiphasic personality inventory(MMPI),toronto alexithymia scale(TAS),life event scale(LES),defense style questionnaire(DSQ) and social support rating scale(SSRS) to explore the physiological and psychosocial risk factors of the patients with somatoform disorders.Results The score of immature defense styles of the study group(4.04±0.89) were higher than those in the control group(3.43 ± 0.65)with significant difference (P＜0.05).The total and factor scores of TAS of study group((86.20±11.15),(21.12±3.28),(26.08±3.86),(18.21±4.69),(23.44±5.60)) were higher than control group((65.00±10.12),(12.43±5.18),(15.64±5.57),(15.56±3.16),(18.71 ±4.30)) with significant difference (P＜0.05).The MMPI scale scores of Hs (hypochondriasis),D (depression),Hy (hysteria),Men-Nancy (Mf),Paranoid (Pa),Psychotic (Pt) were higher in patients with somatoform disorder ((72.79± 10.50),(68.46±13.63),(79.03±12.12),(51.72±7.74),(57.98±10.60),(54.98±8.83)) than those in normal controls((51.66±10.11),(47.96±9.42),(51.47±11.90),(43.66±8.77),(47.67±6.69),(47.48±8.67)) with significant difference(P＜0.05).The total life event score and the negative life event score of LES of the study group ((89.66±68.60),(82.65±65.16)) were higher than those in the control group((56.00±56.79),(39.14± 46.05)) with significant difference (P＜ 0.05).Multiple factors logistic regression analysis showed immature defense styles,higher alexithymia score,higher negative life event score,higher HS,D,Hy of MMPI may increase the risk of somatoform disorders(OR=6.84,9.12,5.83,2.69,1.81,11.20,P＜0.01).Conclusion Patients with somatoform disorder are almost in normal physiological condition.They have the personality characteristics and significant alexithymia.Their social support are almost normal,but they have more negative life events and their defense styles are almost immature.

Objective To determine the effects of maternal rats exposed to chronic unpredictable stress before pregnancy on the behavior and neurobiology of the mother and their offspring.Methods Two-month Virgin female Sprague-Dawley(SD) rats were applied to study.Females were housed with sexually experienced males (ratio 3:1) for propagation after 21-day chronic unpredictable stress.The behaviors of rats and their two-month-offspring were tested.The two-month rats were injected intraperitoneally with BrdU,then the brains were removed and 20 μm frozen sections were used to detect the neurogenesis of hippocampus.Results 1.Open field test:after lactation,CUS + Pre group ((720.52 ± 238.99) cm),CUS group ((995.62 ± 191.77) cm),CON group ((464.95 ±210.11)cm) and CON + Pre group((740.76 ± 281.48)cm) had statistic difference in total distance(P ＜ 0.05).The total distance((1281.10 ±247.89)cm) and border distance((1153.20 ±238.19)cm) in female two-monthprogeny were higher than these in male two-month-progeny ((1074.70 ± 263.35) cm,(957.28 ± 82.94) cm) in CUS + Pre group (P ＜ 0.05).2.Sucrose consumption test:after lactation,the sucrose intake ((13.00 ± 3.46) g)and sucrose consumption percentage((87.00 ±9.01)％) in CUS + Pre group were higher than that in CUS group ((8.13 ± 3.36) g,(79.06 ± 6.45) ％,P ＜ 0.05).The sucrose intake ((12.43 ± 3.31) g) and sucrose consumption percentage((86.90 ± 5.80)％) in CON group were higher than that in CUS group ((8.13 ± 3.36) g,(79.06 ± 6.45) ％,P ＜ 0.05).The sucrose intake ((14.71 ± 4.39) g) and sucrose consumption percentage ((91.54 ± 1.89) ％) in CON + Pre group were significantly higher than those in CUS group ((8.13 ± 3.36) g,(79.06 ± 6.45) ％) (P ＜ 0.01).3.Immunohistochemistry:there was no statistic difference on the new neuron in dentate gyrus of hippocampus in both female and male two-month-progeny of CUS group and CON group((1.18 ±0.37) cells,(1.24 ± 0.41) cells,(1.38 ± 0.47) cells,(1.41 ± 0.35) cells) (P ＞ 0.05).Conclusion The 21d CUS before pregnancy induce the anxiety-like behavior and depressive-like behavior in maternal rats,and lactation can attenuate influence of stress to protect maternal rats.There is no effect on the behavior and cell proliferation of hippocampus in adult progeny by chronic unpredictable stress exposure before pregnancy.However,there is the difference of anxiety-like behavior in both female and male two-month-progeny.
