BACKGROUND: There are many studies on the quality of life (QOL) of patients with breast cancer at home and abroad at present. But the effect of antidepressants on the QOL of depressive patients with breast cancer is not clear yet.OBJECTIVE: To investigate the effect of fluoxetine on the QOL of depressive patients with breast cancer.DESIGN: A self-controlled and observational comparative study of taking the patient as the subjects.SETTING: The research institute of medical psychology and psychiatric specialty in two universities and a psychiatric department in a city hospital.PARTICIPANTS: Sixty-three female post-operative patients with breast cancer hospitalized in the First Affiliated Hospital and Second Affiliated Hospital of China Medical University and Dalian Tumor Hospital, with an average age of (50 ± 9) years.INTERVENTIONS: Sity-three depressive patients with breast cancer were treated with fluoxetine for 8 weeks. Treatment emergent symptom scale (TESS) and relative laboratory examinations were used to evaluate the safety of fluoxetine to depression and anxiety of depressive patients with breast cancer. QOL of WHO scale was used to assess the QOL of the patients before and after administration.MAIN OUTCOME MEASURS:①Score of every index of QOL of WHO;②Side effects and adverse effects.RESULTS: The scores of physiology, psychology and independence in QOLafter 8 weeks' administration(16.30 ±2.17, 14.41 ± 1.85, 16. 90 ± 1.53)were significantly higher than those before grouping (13.61 ±2.46,12.98 ± 2.65, 13.65 ± 2.45) ( t = 6.52, P ＜ 0.01; t = 2.41, P＜ 0.05; t= 8.93, P ＜ 0.01 ). No obvious side effect was observed during administration.CONCLUSION: Fluoxetine can significantly improve the QOL of patients with breast cancer and there are fewer side effects during the treatment.

Objective To research the effects of tianeptine and lithium on expression of pCREB in hippocampus of chronic stress depression rats. Methods All the experimental rats were divided by random into : Group of depression,Group of tianeptine,Group of lithium and Group of control. The rats of Group of depression, Group of tianeptine and Group of lithium were applied stress for 21 days,and meanwhile Group of control had no stress. The rats of Group of tianeptine were fed with tianeptine (50 mg/kg) , Group of lithium were fed with lithium (60 mg/kg) , while another groups were fed with normal sodium of the same volume. The ethology examination was performed by using method of open-field and experiment of fluid consumption. The expression of pCREB was detected by Western-blotting method. Results After the chronic stress,the horizontal crossing numbers,the erection times,the modification times and the percentage of sacchar-consumption of the rats of Group of depression were 23.2±23.0;8. 1 ±7.2; 3.6 ±3.5 and (55.4 ±11.7)% respectively, which were less than Group of control (46.0±18.9;20.3±11.3;8.4±2.7 and (68.5 ±8.2)% ; P＜0.01). The horizontal crossing numbers(28. 1 ±23.0) ,the erection times(12. 1 ± 9.4) and the modification times(5.5 ±3.2) of Group of tianeptine are less than those of Group of control (P ＜ 0. 05), but no significant difference compared with Group of depression; the percentage of sacchar-consumption(62.7 ± 10.6) % ,Group of tianeptine was more than Group of depression (P＜ 0.05 ) , but no obvious difference with Group of control. The horizontal crossing numbers, the erection times, the modification times and the percentage of sacchar-consumption of Group of lithium were less than those of Group of control (P ＜ 0.05), more than those of Group of depression but no significant difference (P ＞ 0.05). In Westernblotting method,the level of pCREB in the hippocampus of Group of depression was less than that of Group of control (P＜ 0.01); that of Group of tianeptine was more than that of Group of depression (P ＜ 0.01) but no obvious difference with Group of control; that of Group of lithium was less than that of Group of control (P＜0. 01) and more than Group of depression (P＜0.01). Conclusion Tianeptine could reverse the reduction of expression of pCREB in hippocampus of chronic stress depression rats and lithium partly did it.

Methods: 113 children with ADHD were tested with IVA-CPT and EEG biofeedback. The sensitivity, specificity, misdiagnosis rate and missed diagnosis rate of these two methods were assessed according to the criteria of DSM-Ⅳ. Results: The sensitivity of IVA-CPT for the diagnosis of children with ADHD was 92.54, the specificity was 76.09%, misdiagnosis rate was 23.911% and missed diagnosis rate was 7.46%. And the sensitivity of EEG biofeedback for the diagnosis of children with ADHD was 83.58%, the specificity was 82.61%, misdiagnosis rate was 17.38 and missed diagnosis rate was 16.42%. Conclusion: Relatively, for diagnosis of children with ADHD, sensitivity is higher and missed diagnosis rate is lower, specificity of EEG biofeedback is higher and misdiagnosis rate is lower .

Objective To investigate the antitumor mechanism of sodium arsenite on human gastric carcinoma cell line SGC-7901 in vitro. Methods MTT assay, light microscopy, electron microscopy, flow cytometry, and immunocytochemical staining were used to analyze the effect of sodium arsenite on biologic behavior of SGC-7901 cells. Results Sodium arsenite (2.50 ～ 40.00 ?mol/L) could inhibit the growth of gastric carcinoma cells, it depended on the duxation and concentration, and its 50% inhibitory concentration(IC50) was 8.69 ?mol/L after 72 hours' treatment. SGC-7901 cells were arrested significantly in G2/M phase treated with sodium arsenite for 48 and 72 hours. SGC-7901 cells presented typical morphologic feature of apoptosis and necrosis after exposure to sodium arsenite. Sodium arsenite up-regulated Caspase-3 protein expression in SGC-7901. Conclusion Sodium arsenite could obviously inhibit the proliferation of SGC-7901 cells, induce cell cycle arrest and apoptosis and necrosis of the cells. its mechanism is possibly associated with inhibition of elimination of ROS and the up-regulated expression of Caspase-3 protein.

Medical psychology and psychiatry is the obligatory courses for five-year and seven-year medical students. With the rapid changes of society and continuous improvement of medical services , it is necessary to adjust and integrate the teaching content of these two courses. Teaching order of some chapters in the teaching syllabus was not helpful for students to understand the teaching content. Some teaching content was repetitive. Part of the self-study content urgently needs to teach with the development of the society and changes in disease spectrum. After the adjustment , the teaching content of the curricu-lum with strong pertinence was clear and coherent. It improved the teaching efficiency and knowledge of students;therefore, the curriculum is widely praised by the students.

Objective To explore the similarities and differences in amplitude of low frequency fluctuation ( ALLF) between patients with first-episode drug-naive schizophrenia and offspring of schizophrenia patients.Methods ALFF values were estimated by measuring the Blood Oxygen Level-Dependent ( BOLD) signal using resting state function-al magnetic resonance imaging ( rs-fMRI) .The fMRI date were acquired from 23 patients with first-episode drug-naive schizophrenia (SZ), 25 offsprings of schizophrenia patients (OS) and 29 age -and gender -matched health controls ( HC) .The ALFF value of each subject was calculated by MATLAB-based DPARSF software.Results Compared with HC, the ALFF values of SZ and OS were significantly different in the left posterior part of the inferior temporal gyrus, left parahippocampal gyrus, left hippocampus, right postcentral gyrus and bilateral precuneus.The ALFF values were not signif-icantly different between these two groups in the aforementioned regions.Compared with OS and HC, the ALFF values of SZ were significantly different in the left anterior part of the inferior temporal gyrus, left temporal pole and bilateral calcarine cortex.But there was no significant difference between OS and HC.Conclusions The brain function is abnormal in pa-tients with early schizophrenia and offspring of schizophrenia patients.The significant difference of ALFF in the left posterior part of the inferior temporal gyrus, left parahippocampal gyrus, left hippocampus, right postcentral gyrus and bilateral pre-cuneus may suggest the heredodiathesis-related brain functional alterations.Significant difference of ALFF in the left ante-rior part of the inferior temporal gyrus and the left temporal pole bilateral calcarine cortex may suggest the disease-related brain alterations.

Objective To explore the clinical and laboratory characteristics of patients with dengue fever(DF)in Guangzhou from July to September in 2006 and to improve the awareness of dengue virus infection for physicians.Methods Clinical data of 277 patients with DF admitted to our hospital in Guangzhou were retrospectively analyzed.Dengue virus was isolated from patients' blood specimens by C6/36 cell culture and typed by reverse transcriptase-polymerase chain reaction(RT-PCR)assay and gene sequencing.Results Age of the 277 patients,148 males and 129 females,averaged 36 years with a standard deviation of 17 years,ranging from 9 months to 78 years.Their most common symptoms included fever(100.0%),skin rash(85.2%),headache(69.3%),myalgia(51.3%),bone soreness (39.0%)and nausea or vomiting(39.4%),and leucopenia and/hromboeytopenia occurred in 75.5% and 62.5% of them,respectively.Elevated alanine aminotransferase(ALT)was found in 59.6%,elevated aspartate aminotransferase(AST)in 81.6%,and hypopotassemia in 53.8% of them.Serum positivity of antibody against dengue virus IgM was 90.6%,which could be detected 3 to 10 days after onset of the illness,with a mean of 6.2 days with a standard deviation of 1.9 days.Cell-cultured virus from 20 patients were identified as typed by RT-PCR and RNA sequence analyses.All patients were clinically classified as typical DF and all of them completely recovered.Conclusions DF during this epidemic in Guangzhou was caused by dengue virus-1,with typical manifestations in all the patients but more damage in the liver.Some patients demonstrated hypopotassemia,but no dengue hemorrhagic fever or dengue shock syndrome was found.All the patients experienced a good prognosis with timely diagnosis and treatment.

In order to observe the nutrition state in the severe multiple trauma patients undergoing adjuvant recombinant human growth hormone (rhGH) nutritional support therapy, 45 patients with severe multiple traumas (ISS>25) were randomly divided into 3 groups. All the 3 groups had been supplied with nitrogen and caloricity according to the need of patients for 16 days. The rhGH therapy started 48 h after surgery and lasted for 14 days in two rhGH-treated groups in which rhGH was 0.2 and 0.4 U/(kg . d) respectively, and the resting group served as control one. The levels of nitrogen balance, prealbumin and safety variables (blood sugar, Na+, TT3 and TT4) were observed and compared among the three groups. The levels of nitrogen balance on the postoperative day (POD) 3 and 5 in the rhGH-treated groups were -1.28+/-3.19, 5.45+/-2.00 and -0.18+/-2.55, 6.11+/-1.60, respectively, which were significantly higher than those in the control group (-5.17+/-1.68 and -1.08+/-3.31, P<0.01). The values of prealbumin on the POD 3 and 5 in the rhGH-treated groups were 180.19+/-27.15, 194.44+/-50.82 and 194.94+/-29.65, 194.11+/-16.17, respectively, which were significantly higher than those in the control group (117.42+/-19.10 and 135.63+/-28.31, P<0.01). There was no significant difference between the rhGH 0.2 U/(kg . d) group and rhGH 0.4 U/(kg . d) group in both of the levels of nitrogen balance and prealbumin. It is concluded that the nutritional support therapy with adjuvant rhGH which starts 48 h after surgery improves the nutrition state of the patients with severe multiple trauma. It is safe for severe multiple trauma patients who accept rhGH at the dose of 0.2 and 0.4 U/(kg . d).

Objective To research the changes of regional gray matter volumes in first-episode, medication naive females with major depressive disorder. Methods Magnetic resonance imaging and voxel-based mor-phometry were used to compare regional gray matter volumes between 14 medication-naive female participants with a first episode of major depressive disorder ( MDD) ( age( 29. 5 ±6.8) years, number of education years(11.4 ± 2. 7) years, duration of iIIness(5.4 ±5. 2 ) months, H AMD score(27.6 ±5.5)) and 14 female healthy comparison participants (HC) (age(29.5 ±6.9)years,number of education years( 12. 2 ±3. 3)years,HAMD score(2. 1 ± 1.9)). Results Volumes of bilateral anterior cingulate cortex ( ACC) and right amygdala were significantly smaller in the MDD group than those in the HC group. Conclusion These results suggest that volume reductions in ACC and amygdala in females with MDD are present at illness onset.
