Objective To study the similarities and differences of personality in patients with body-dysmorphic disorder(BDD),obsessive-compulsive disorder(OCD) and ordinary person.As well as to provide information for clinical therapy. Methods All BDD patients( n =29),OCD controls( n =30) and normal controls( n =30) completed Self Rating Scale of Body Image (SRSBI) and Minnesota Multiphasic Personality Inventory (MMPI). Results Ten clinical scales score of MMPI in BDD were found significant higher than normal controls which including hypochondriasis,depression,hysteria, psychopathic deviate, masculinity-femininity, paranoia,psychasthenia,schizophrenia,and social introversion.Four clinical scales[(68.18±8.70),(65.44±8.73),(61.39±9.37),(60.70±12.88)] were significant higher than OCD controls[(61.09±13.29),(58.82±10.26 ),(56.23±9.58),(50.03±12.63)] which including psychopathic deviate,psychasthenia,schiaophrenia and social introversion( P ＜0.05). But hysteria scale was significant lower than OCD controls( P ＜0.01). Conclusion BDD patients have abnormal personality which is more significant than OCD patients. Significant abnormal personality are likely the psychopathology of BDD from which the clinic symptom produced.

The aim of this study is to determine whether seeded Dacron with autologous venous tissue fragments shows significant 6-keto-prostglandin F 1? (6 K PGF 1? )production after in vivo implantation.The Dacron grafts seeded with autologous venous fragments were implanted into the inferior vene cava(IVC)of the 13 canines as seeded group;and the control group (8 canines),in which grafts were only preclotted with fresh blood. Plasma 6 K PGF 1? and TXB 2 were assessed at different time.All of the specimens explanted at exsanguination were observed with light microscopy and sanning electron microscopy and the amounts of 6 K PGF 1? from the luminal surface were assessed using ridioimmunoassay. The results showed that the total patency rate of the explanted vessels was higher in seeded group (61.5%) than that in control group ( 25% ),and that endothelial cells lined the whole luminal surface of Dacron at the 14th day after operation in seeded group,but thrombus covered the surface of Dacron at the 14th day in control ones. The level of 6 K PGF 1? from plasma and the luminal surface of Dacron grafts in seeded group was higher,but the level of plasma TXB 2 was lower than that in control group. It can be concluded that seeding Dacron with autologous venous fragments makes a new endothelial lining possible at two weeks,and can release more 6 K PGF 1? and thus lead to an improved patency rate of canine IVC reconstructions,so the graft patency might be determined according to the changes of plasma 6 K PGF 1? and TXB 2 level.

Objective To analyze the relationship between serum Th1/Th2 cytokines levels and autoantibodies against thyroid, and explore the role of Th1/Th2 cellular immunity imbalance in the pathogenesis of autoimmune thyroid diseases(AITD). Methods 21 patients with Graves'desease(GD), 18 cases with Hashimoto's thyroiditis(HT), 17 cases with non-toxic nodular goiter(NTNG) and 20 healthy subjects were enrolled in this study. The serum concentrations of their Th1 cytokines (IFN-?,IL-2) and Th2 cytokines (IL-4,IL-10) were assayed by ELISA. The serum levels of their thyrotropin receptor antibodies(TRAb), thyroglobulin antibodies (TGAb) and thyroid peroxidase antibodies(TPOAb) were measured by routine methods. The relationship between the serum Th1, Th2 cytokines levels and serum TRAb, TGAb, TPOAb levels were analyzed. Results The serum levels of IL-4 and IL-10 in patients with GD were significantly higher than those in patients with HT,NTNG and healthy subjects(P

AIM: To investigate atypical protein kinase C(aPKC), extracellular signal regulated kinnase (ERK) regulating NF-E2-related factor 2 (NRF2)-?-gutamylcysteine synthetase (?-GCS) and the effect on lung of rats with chronic obstructive pulmonary disease (COPD). METHODS: The rat COPD model was established by intratracheal instillation of lipopolysaccharide twice and exposure to cigarette smoke daily. The ?-GCS activity was measured. The expression of ?-GCS mRNA in lung tissue was examined by in situ hybridization (ISH) and reverse transcription-polymerase chain reaction (RT-PCR). The protein expressions of p-aPKC?/?, p-ERK, NRF2 and ?-GCS in lung tissue were detected by immunohistochemistry (IH) and Western blotting, respectively. RESULTS: (1) The ?-GCS activity was higher in COPD group than that in control group. (2) The expression of ?-GCS mRNA in the COPD group was stronger than that in control group. ISH showed that the ?-GCS mRNA was expressed in alveolar epithelium and bronchiolar smooth muscle cell in the COPD group. (3) The protein expressions of p-aPKC, p-ERK, NRF2, ?-GCS were significantly higher than those in control group. IH showed that p-aPKC, p-ERK, NRF2, ?-GCS proteins were expressed in alveolar and bronchiolar epithelium in the COPD group. (4) There was a positive correlation between NRF2 and ?-GCS. ?-GCS mRNA, p-aPKC?/?, p-ERK were also positively correlated with NRF2. CONCLUSION: By upregulating the signal transduction of NRF2-?-GCS, the ERK and aPKC?/? may play an important role in the mechanism of COPD formation.

Objective To explore the effects of combined exercise program ( fun game + rope skip-ping + figure running) on executive function ( EF) in primary students with Chinese learning difficulties. Methods Fifty-four Chinese learning disabled students were selected and randomly divided into experimen-tal group and control group. Three tasks ( the Flanker task,the 1-back task and the More-odd shifting task) were used to measure pupil’ s EF ( inhibition,updating,shifting) . Results ( 1) Compared with the control group,the primary students with Chinese learning difficulties in experimental group showed a significant en-hancement in executive function (F(1,43)=9.45, P<0.01). (2) The positive effects of 10 weeks combined ex-ercise program on executive function in primary students with Chinese learning difficulties were different. Specifically,a beneficial effect on updating(F(1,43)= 11.37, P<0.01) was got,but there were no significant effects on inhibition (F(1,43)=1.52, P>0.05) and shifting(F(1,43)=2.57, P>0.05). Conclusion The effect of combined exercise program ( fun game+rope skipping+figure running) plays a positive role in promoting updating function of primary school students with Chinese learning difficulties.

Objective To investigate the expression of CD44V6 in thyroid neoplasms and its significance. Methods The expression of CD44V6 in paraffin-embeded thyoid carcinoma tissue from 100 patients (50 with lymph node metastasis,50 without) and 20 patients with thyroid adenoma was measured by immunohistochemistry staining. Results Positive expression of CD44V6 in the group of thyoid carcinoma was 72%, significantly higher than the group of thyroid adenoma.Positive expression of CD44V6 in the group of thyoid carcinoma with lymph node involvement was 90%,significantly higher than the group of thyoid carcinoma without lymph node involvement.In patients with different pathological grade,different clinical stage and different survival time, the positive expression of CD44V6 was significantly different. Conclusions The results suggest that CD44V6 can be regarded as an valuable molecular markers to distinguish benign thyroid tumor from malignant tumor, to predict lymph node metastasis and prognosis.

AIM: To investigate the expression of PPARγ and Nrf2/γ-GCS-h in inflammatory cells in bronchoalveolar lavage fluid(BALF) of guinea pig with bronchial asthma of acute episode, and to explore the roles of PPARγ on Nrf2/γ-GCS-h expression. METHODS: Forty adult male guinea pigs were randomly divided into 4 groups (10 guinea pigs in each group): control group (group A), asthmatic group (group B), dexamethasone treatment group (group C) and rogridone treatment group (group D). The asthmatic model was established by an ovalbumin challenge method. BALF was collected, and the total cell count and the proportion of the inflammatory cells were measured. After centrifugation, the concentrations of ROS and MDA in the clear supernatant were detected. The methods of in situ hybridization and immunohistochemistry were used for detecting the expression of PPARγ and Nrf2/γ-GCS-h at mRNA and protein levels. RESULTS: The proportion of eosinophils (EOS) in BALF in group B was significantly higher than that in groups A, C and D (P<0.01). The concentrations of ROS and MDA in BALF of group B was the highest. The difference of ROS and MDA was statistically significant (all P<0.05) as compared to the control. The results of immunohistochemistry and in situ hybridization indicated that the A value was the lowest in group B as compared to that in groups A, C and D (all P<0.01). In group B, the positive correlations were observed between PPARγ and Nrf2/γ-GCS-h, between γ-GCS-h and Nrf2. A negative correlation between the proportion of EOS in BALF and the expression of PPARγ and Nrf2/γ-GCS-h was also observed (all P<0.05). CONCLUSION: In acute asthmatic models induced by ovalbumin, the expression of PPARγ and Nrf2/γ-GCS-h is decreased, and PPARγ may up-regulate the expression of Nrf2/γ-GCS-h to inhibit the inflammatory and oxidative reactions, indicating a new way for prevention and treatment of bronchial asthma.
