Objective To investigate the type A behavior, brain-derived neurotrophic factor (BDNF) and hypersensitive C-reactive protein (hs-CRP) levels in serum in patients with post stroke depression (PSD) ,and explore the correlation between them.Methods The HAMD-17 was used to assess the severity of depressive symptoms in patients with stroke (n=116).TABP,Social Support Scale, MMSE, NIHSS,mRS and BI were measured in PSD group(n=36) and non PSD group(NPSD group, n=80);fast blooding samples were analyzed with BDNF and hs-CRP in patients with PSD group, NPSD group and healthy controls (NC group).Results (1) The incidence of acute PSD was 31.03％.(2)The constituent ratio of type A behavior(83.33％ vs 57.50％), CH scores, TH +CH scores were significantly higher in PSD group than NPSD group(P＜0.01).Social Support Scale scores,MMSE scores were significantly lower in PSD group than NPSD group(P＜0.01, P＜0.05).NIHSS scores,mRS scores were significantly higher in PSD group than NPSD group, BI scores were significantly lower(P＜0.01).(3) The levels of serum BDNF,hs-CRP in the PSD group,the NPSD group and the normal control group were respectively (BDNF (617.24(274.98,976.22)) pg/ml, (938.19(615.88,1 714.76)) pg/ml, (4 149.46(1 658.83,7 583.34)) pg/ml);(hs-CRP(6.47(2.66,11.21)) mg/L, 1.77(0.74,6.51) mg/L, (0.86(0.47,1.59)) mg/L).The BDNF levels of PSD group were significantly lower and hs-CRP levels were significantly higher than NPSD group (P＜0.01).(4) The severity of depression was positively correlated with CH,TH+CH scores(r=0.38, P＜0.05;r=0.43, P＜0.01).CH scores were negatively correlated with social support(r=-0.38, P＜0.05),and were positively correlated with hs-CRP levels(r=0.34, P＜0.05).Conclusion In patients with post stroke depression,the BDNF levels decrease and hs-CRP levels increase,but severity of depression and cognitive function are not correlated with BDNF levels.Hostility and competition(CH) are correlated with the increasing hs-CRP levels.Patients with type A behavior, especially high CH scores, have immune system dysfunction and lower social support.Hostility and excessive competition are psychosocial risk factors occurring PSD.

Objective: To study psychosocial factors and immunity of patients with generalized anxiety disorder Method: 30 patients with generalized anxiety disorder (GAD), 25 patients with neurotic depression and 32 normal controls were collected and assessed with LES (life event scale), SCSQ (simplified coping style questionnaire) and EPQ (Eysenck personality questionnaire) The blood level of IL-2, and rates of NK cell and CD3+ cell of them were also measured Result: The number of negative life events and LEU of negative life events of GAD group were higher that of normal controls, but lower than that of neurotic depression group Their total life events were also more than that of normal controls They had less positive coping than normal controls, more negative coping than both normal controls and patients with neurotic depression Their N score of EPQ was higher than that of normal control and had no significant different to that of patients with neurotic depression They also had higher levels of IL-2 than that of the other two groups There was no significant difference in rates of NK cell and CD3+ cell among all three groups The level of IL-2 was negatively correlated to the number of total life events and L score of EPQ, positively correlated to the rate of NK cell Conclusion: Patients with GAD have psychosocial stress in their life, they incline to negative coping, having unstable mood and impaired immune function Psychosocial stress has influence on immunity

ObjectiveTo investigate the hypersensitive C-reactive protein(hs-CRP),level in serum and the heart rate variability(HRV) in patients with dysthymic disorder,and explore the possible psychological and physiological mechanisms.MethodsPHI and short-term HRV were measured in 42 patients with dysthymic disorder( DD group),33 patients with major depressive disorder ( MD group)and 30 heathy controls( NC group),fasting blood samples were also analyzed with high-sensitivity C-reactive protein (hs-CRP).Results ( 1 ) DD group gained higher score in the somatization,anxiety,psychopathic deviate and hypomania than the MD group(P＜0.05 or P ＜ 0.01 ).(2)The standard deviation of differences between the consecutive RR intervals (SDNN),the percentage value of consecutive RR intervals that differ more than 50 ms(PNN50) and the high frequency band(HF) of DD group were lower significantly than MD and NC groups,the low frequency band(LF),and the ratio of LF to HF power(LF/HF) and hs-CRP level were higher than other two groups (P ＜ 0.05 or P＜0.01 ).(3)The somatization and anxiety were correlated with SDNN,the very low frequency band(VLF),LF and hs-CRP level ( r=-0.27,-0.29,r=0.38,0.33,r=0.41,0.31,r=0.34,0.23,P＜0.05 or P＜0.01).(4)The hs-CRP level in serum were correlated with SDNN,the root mean square of successive RR intervals (RMSSD),the standard deviation of differences between the consecutive RR intervals ( SDSD),VLF,LF,HF and LF/HF ( r =- 0.47,- 0.45,- 0.45,0.26,0.46,-0.51,0.10,P ＜ 0.05 or P ＜ 0.01 ).ConclusionThe patients with dysthymic disorder have significant somatization and anxiety,the personality character was mainly resulting in reducing HRV,which is related with the increasing serum hs-CRP level.

Objective:To study the effect of repeated transient ischemic attacks(TIAs)on cumulative injury of cognitive function.Methods:The cognitive condition of 42 patients with repeated TIAs were assessed after each TIA using the event related potential,modified version of Wisconsin card sorting test,trail making test,digit span task,and verbal fluency test.The cognitive condition was compared and analyzed after different attack times.Results:There were significant differences among the cognitive condition after different attack times,latency and amplitude of P300,and detection rate of mild cognitive impairment.With the increase of the attack times,cognitive impairment aggravated gradually,and the detection rate of mild cognitive impairment increased gradually.Conclusions:Repeated TIAs have cumulative injury on cognitive function.The prevention and treatment of cerebral ischemia may become an important approach in decreasing cognitive impairment.

Objective: To study the relationship between immune function and psychosocial factors of patients with malignant tumors Method:37 inpatients with malignant tumors were collected They had no chemotherapy or radiotherapy in the past month and without history of immune disease or medication influencing immune system 37 inpatients of internal department without tumor were collected as control All subjects completed EPQ, SCL-90, SAS, SDS, LES, SSRS and DSQ Researchers assessed their mood with HAMA and HAMD, and their immune function by measuring serum IgG, IgA, IgM, C 3, C 4, CH50 and sub-groups of lymphocyte Results:Study group had lower IgM and less CD 16 + than control The level of IgM was associated with course of disease, educational level, gender, personality, defense style, negative life events and social support The level of CD 3 + was associated with depression in addition to other factors mentioned above Conclusion: Patients with malignant tumors have immune dysfunction, which associated with psychosocial factors such as negative life events, social support and depression

Objective To investigate the value of MR 3D CUBE T2WI sequence in displaying anatomical structure of knee joint.Methods Sixty cases of knee joints (30 cases in lesion group and 30 cases in control group) were scanned with conventional 2D and 3D CUBE T2WI sequence by HDXt 3.0T superconducting magnetic resonance of GE Signa imaging system and hased-array coil.The meniscus,articular cartilage,anterior and posterior cruciate ligaments demonstrated by two sequences were evaluated as excellent,good and poor grade,the results were comparatively analyzed by statistics.Results 3D CUBE T2WI was superior to conventional 2D sequence in displaying of articular cartilage,anterior and posterior cruciate ligaments,and inferior to conventional 2D sequence in displaying of meniscus(all P =0.000).When we put excellent and good levels of image quality as according with diagnostic requirement.The satisfaction rate demonstrating anterior and posterior cruciate ligaments by 3D CUBE T2WI sequence in lesion and control group were 100％,articular cartilage was 93.33％ in control group and 90.00％ in lesion group,while the meniscus was 30.00％ in control group and 33.33％ in lesion group.Conclusion MR 3D CUBE T2WI sequence is a sensitive technique in demonstrating ligaments and articular cartilage of knee joint,but it was inferior to conventional 2D sequence in displaying of meniscus.We should adopt it according to clinical diagnosis.

Objective:To explore psychosocial factors of depressed elderly patients. Methods:33 elderly people with the first episode of depression diagnosed according to CCMD-3, and elderly healthy people were investigated with EPQ, SSRS (social support rating scale), LES (life event scale) and MMSE (mini mental state examination). Results:The rates of psychiatric family history, somatic diseases, risk factors for vascular disease and long-term difficulties were significantly higher in the depressive group than in control group. The score of MMSE was significantly lower in depressive group than in control group. The scores of negative life events and problems in social intercourse were significantly higher in depressive group than in control group. There were lower score of social support and its utility in the depressive group than in control group. The score of neuroticism was significantly higher in the depressive group. Most depressive elderly patients had the personality of neuroticism.Conclusion:Chronic stress, high neuroticism and severe cognitive impairment are important risk factors for depression in late life.[

Objective To investigate the value of CARE Dose 4D technique in decreasing radiation dose and improving image quality of multi-slice spiral CT in adult chest scanning.Methods 100patients of chest CT scanning were equally divided into study group and control group randomly.CARE Dose 4D Technique was used in study group.Effective mAs value,volume CT dose index (CTDIvol) and dose length product (DLP) were displayed automatically in machine while chest scanning; those values and actual mAs value of every image were recorded respectively.The image quality at apex of lung,lower edge of aorta arch,middle area of left atrium and base of lung on every image of 400 images was judged and classified as three level (excellent,good,poor) by two deputy chief physicians with double blind method,the image noise at corresponding parts was measured.Results While setting 80 mAs for quality reference mAs,the effective mAs value in study group most decreased 44 mAs than control group with an average decrease of 9.60( 12.0% ) ,CTDIvol with 4.75 mGy with an average decrease of 0.95 mC y( 11.0% ) ,DLP 99.50% in study group,with 98.0% in control group.But it was higher at apex of lung and base of lung,lower at middle area of left atrium,and similar at lower edge of aorta arch in study group than contrast group.The image noise were lower at apex of lung and base of lung in study group than control group (t =6.299 and 2.332,all P ＜ 0.05 ) ,higher at middle area of left atrium in study group than control group (t=3.078,P ＜0.05) and similar at lower edge of aorta arch in study group than control group (t =1.191,P ＞0.05).Conclusions CARE Dose 4D technique provides a function regulated mAs real-time on line,it not only raises utilization rate of radiation and decreases radiation dose,but also promises and increases image quality in chest CT scanning,and has some clinical significance.

Objective To observe the clinical effect of oral use and acupoint application of Chinese herbal medicine with the actions of strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting in treating pregnant pernicious vomiting. Methods One hundred and twenty-two spleen-stomach deficiency pregnant pernicious vomiting cases were randomly divided into observation group ( N=63) and control group (N=59). At the end of the trial, 2 cases of the control group dropped out, and the total case number was 57 in the control group. Both groups were treated with intravenous infusion, dietary care, daily life and emotional nursing, and oral use of Chinese herbal medicine with the actions of strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting. Additionally, the observation group was given acupoint application of herbs for strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting. The treatment was performed once a day, 4 days constituted one treatment course, and the treatment lasted two continuous courses. The improvement of vomiting, therapeutic effect and the safety were compared between the two groups after treatment. Results ( 1) The total effective rate was 96.8%in the observation group and was 71.9%in the control group, the difference being significant (P<0.01). (2) The time for stopping vomiting in the observation group was significantly less than that in control group (P<0.01). (3) During the treatment, no obvious adverse reaction was found in the two groups. Conclusion Acupoint application of herbs for strengthening spleen and regulating stomach, lowering rebellious Qi to stop vomiting has obvious synergistic effect on the clinical efficiency of spleen-stomach deficiency pregnant pernicious vomiting treated by oral use of herbal medicine, intravenous infusion, dietary care, and daily life and emotional nursing.
