Object To explore the difference of explicit and implicit depression stereotypes for people with major depressive disorder, social public, psychiatrists and nurses.Methods 61 major depressive disorder patients(MDD) ,55 social public people(SPP) and 56 psychiatrists and nurses(PN) were enrolled.All participants were measured by explicit depression stereotype evaluations and implicit association tests.Results There was significantly difference on the positive explicit stereotype scores about depressive stereotypes (DS) among the MDD (2.31±1.60) ,SPP(2.43±1.55) and PN(3.12±1.58)(F=23.22, P=0.00).LSD test showed significantly difference on the positive explicit stereotype scores about DS between the MDD and PN,with the similar to the SPP and the PN(P＜0.05).There was significantly difference on the negative explicit stereotype scores about DS among the MDD(4.09±2.22), SPP (3.97±2.01) and PN (3.23± 1.64) (F=30.16, P=0.00).LSD test showed significantly difference on the negative explicit stereotype scores about DS between the MDD and PN,with the similar to the SPP and the PN (P＜ 0.05).There was no significantly difference on the implicit stereotype scores about DS among the MDD,SPP and PN(F=2.03, P=0.12).Conclusion The MDD,SPP and PN show negative impicit stereotype about DS.However,the PN shows positive explicit stereotype about DS.

Objective To investigate the relationship between of the serum homocysteine (Hcy) level and the occurrence and severity of diseased coronary arteries in patients. Methods The total serum Hcy content was determined in sixty-seven patients with diseased coronary arteries and forty-three normal subjects. They were all subjected to coronary artery angiography for evaluation. Using the Gensini's scoring system the degree of severity of of pathology the coronary arteries were assessed. Other risk factors were analyzed in addition to Hcy and Gemini's scores. Results The total serum level of Hcy in patients with diseased coronary artery was significantly higher compared with the normal controls (P

Background and purpose:Thyroglobulin antibody (TgAb) is often positive in papillary thyroid carcinoma (PTC) patients. This study aimed to investigate the effect of TgAb on radioiodine ablation efficacy in PTC patients.Methods:A total number of 329 PTC patients with no distant metastasis were included and classified into 2 groups[G1 group (>115 U/mL,n=84) and G2 group (<115 U/mL,n=245)], G2 group was further divided into 2 subgroups[S1 (>40 U/mL,n=31) and S2 (<40 U/mL,n=214)], before131I ablation. The median follow-up time was 24 months after a total or subtotal thyroidectomy and subsequent131I ablation. The efficacy in terms of131I ablation success rates (IBR) between two groups were compared and the influencing factors were analyzed according to criteria posed by 2015 American Thyroid Association Guidelines, then the effect of131I dose on IBR was also explored.Results:Female and younger age were more prevalent in patients with high TgAb (P<0.05). The G1 group presented lower IBR over the G2 group (35.7%vs 72.7%,P=0.000). Moreover, S1 group also presented lower IBR over S2 group (54.8%vs 75.2%,P=0.017), indicating the adverse effect from high titer TgAb on IBR. No matter high or low dose, the G1 group presented lower IBR (34.1%vs 71.9%, 37.2%vs 73.2%;P=0.000). However, IBR did not differ in G1 or G2 group either with high or low dose131I (P>0.05). TgAb was the only adverse indicator correlating with IBR in multi-logistic regression analysis (P=0.018).Conclusion:TgAb could negatively affect131I ablation efficacy, while increasing the dose of131I failed to improve the success rate in such cases.

Objective To evaluate the application of the flurescence-guided resection in gliomas surgery. The value and the advantages of this system for glioma resection was assessed, points for attention of application were discussed. Method 14 patients with gliomas in different region of the brain were performed flurescence-guided resection by using high-dose fluorescein sodium . Results Of our cases, according to the imaging data, total lesion removals were achieved in 11 patients (78.6%). The clinical status of all patients showed improvement without complication after surgery, the time of surgery and the days in hospital were both shortened than those of routine method of surgery. Conclusion The flurescence- guided resection is reliable and does accurate location in surgical treatment for gliomas. It increases rate of total lesion removal of glioma without injuring the adjacent functions.

131 I-metabolizing genes are markers for differentiation of thyroid carcinoma.The loss or down-regulation of these genes represents progression of dedifferentiation,which results in low 131 I uptake and suggests a poor prognosis.The mechanism of dedifferentiation of DTC is important for treatment.This article reviews the mechanism of dedifferentiation from 131I radiation damage,gene mutation,tumor markers and protein.

Objective:To evaluate the biochemical and structural changes of apatinib in patients with progressive radioactive iodine-re-fractory differentiated thyroid cancer (RAIR-DTC). Methods:The participants (n=10) were followed up since March 2016. Treatment ef-fect was evaluated in using both biochemical [thyroglobulin (Tg) and thyroglobulin antibody (Tg-Ab)] and structural responses (target lesions, TL). Adverse events were also recorded over time. Results:The median follow-up was 7.9 months. The Tg level declined rapid-ly within 6 weeks after apatinib treatment, and the average decline ranged from 60%to 90%, indicating the immediate biochemical re-sponse of apatinib in progressive RAIR-DTC. The Tg level tended to stabilize thereafter. However, the Tg level rebounded by 4%–135%when withdrawal was performed for 3–14 days. The number of TLs decreased rapidly within 8 weeks, and the average decreased ranged from 40%to 60%, indicating the presence of rapid structural responses. Thereafter, the number of TLs continued to stabilize. TLs, in contrast to Tg, were not significantly affected by drug withdrawal. The rate of change in Tg (Tgvn) was positively correlated with the rate of change in TL (TLvn) [TLvn=0.17×Tgvn+0.50 (r=0.56, P<0.05)]. The apatinib dose was adjusted due to adverse events, which could be relieved after 3 to 14 days of withdrawal. Apatinib can effectively control the disease even at a reduced dose of 250 mg/d. Conclusion:Apatinib treatment showed a fast and sustainable biochemical and structural responses. Tg could be regarded as an objec-tive indicator. Tgvn is positively correlated with TLvn, and the response of Tg is more sensitive than that of TLs.

Objective To investigate the relationships among cerebellar mutism (CM), relapsed medulloblastoma (MB) and the primary tumor location.MethodsA retrospective analysis was conducted in 114 children over 3 years old with MB from November 2011 to April 2015.ResultsThe median onset age was 84.7 months (36.4 to 184.7 months) in 114 children with MB (77 boys and 37 girls), of whom there were 48 cases of recurrence. There were twenty two cases of CM and the overall incidence of CM was 19.3% (22/114). The incidence of CM was 19.7% (13/66) in non-recurrent cases and 18.8% (9/48) in recur-rent cases, and there was no signiifcant difference between two groups (P=0.899). The incidence of CM was 17.6% (9/51) in cas-es with primary tumor in the fourth ventricle, 7.1% (1/14) in cases with primary tumor in the cerebellar vermis, 21.4% (3/14) in cases with primary tumor in both fourth ventricle and cerebellar vermis, 45.5% (5/11) in cases with primary tumor in fourth ven-tricle and other parts of the brain, and 50.0% (4/8) in cases with primary tumor in cerebellar vermis and other parts of the brain. No CM incidence was observed in cases with primary tumor in central nerve system except for the fourth ventricle and cerebellar vermis. The incidence of CM between the cases with fourth ventricle/cerebellar vermis involvement and those without fourth ventricle/ cerebellar vermis involvement had signiifcant difference (P=0.039). ConclusionsThere is no relationship between CM and relapsed MB. Children with MB whose primary tumor is located in the fourth ventricle and/or the cerebellar vermis is susceptible to CM.

Objective To study HRCT appearances,clinic value and pathological fundament of the pulmonary honeycombing.Methods 60 patients including three groups with pulmonary honeycombing underwent HRCT scan.The comparative study of HRCT-pathology was done in 6 pulmonary postmortems with honeycombing.Results On HRCT images,honeycombing cysts were round-like with air inside,the cyst walls included remains of pulmonary inherent components and hyperplastic fibrotic tissue in pathology.The diameter of cysts was small,58 cases of them belonged to small group(90.6%).The distribution of lesions was mainly at lower(47cases,71.9%)and peripheral lung zone(52cases,81.3%),but there were differences in different type of the diseases.The cysts might become larger and it is impossible to recovery.Conclusion The honeycombing cysts appear as cystic cavities arranging as multiple layers,the cystic walls consist of different tissues in pathology,that are the manifestations of the end-stage of pulmonary fibrosis.HRCT appearances in different patients in three groups were different.

Objective To investigate the distribution of ideal cardiovascular health status in Chinese health checkup population. Methods Subjects were enrolled from a health checkup population coming to the PLA health management center from Sept 2009 to Mar 2016. Modified with China's specifications, lifestyle and checkup data were collected and analyzed according to the American ideal cardiovascular health standard. Results A total of 37664 people were included in the study, of whom 72.88%were male and 27.12%were female. Comprehensive analysis showed that, among 7 health indicators including smoking, physical activity, diet, fasting blood glucose, blood pressure, total cholesterol and body mass index, there were only 43 subjects (0.11%) whose lifestyle reached the ideal cardiovascular health status, 11 subjects were in the poor cardiovascular health status, accounting for 0.03%. The rest of the subjects were in the intermediate levels of cardiovascular health status. There was a large gap between the daily diet intake and the dietary recommendation, and there was also a large gap between the actual level physical activity and the ideal level of physical activity recommended by related guidelines, indicating that unhealthy diet and inadequate physical activity are two bottleneck factors. Dairy product intake has the lowest satisfaction ratio, followed by vegetable and fruit intake. Most subjects (94.10%) showed insufficient physical activity. The percentage of three status of cardiovascular health among young, middle-aged and elderly subjects differed significantly (χ2=1200, P=0.000), and presented an increasing trend of ideal cardiovascular health and a declining trend of poor cardiovascular health status with age from youth to middle age, to the elderly, which reflected insufficient physical activity especially among the young people, and then the middle-aged. Meanwhile, the proportion of ideal cardiovascular health in men was higher than that in women. Conclusion The rate of ideal cardiovascular health is relatively low in the study population, unhealthy diet and inadequate physical activity are two bottleneck factors. Encouraging people to develop good eating and exercise habits might be the most effective method to improve population's ideal cardiovascular health status.
