Objective To investigate the changes of cerebral regional glucose metabolism and regional homogeneity (ReHo) and their relation in patients with major depression disorder (MDD) using 18F-FDG PET/CT and functional MRI (fMRI).Methods A total of 18 MDD patients (6 males,12 females,age:(33.00±7.59) years) and 17 healthy controls (6 males,11 females,age:(34.59±8.96) years) underwent 18F-FDG PET/CT and fMRI.The changes of glucose metabolism on PET and ReHo on fMRI were analyzed individually by SPM and ReHo fMRI 1.0 software.Pearson correlation analysis was used.Results Compared with the glucose metabolism of control subjects,those of MDD patients decreased in the bilateral superior,middle and inferior frontal gyri,bilateral superior and middle temporal gyri,bilateral anterior cingulate cortices,bilateral putamina and caudate nuclei and the left pallidum.Meanwhile the glucose metabolism increased in the bilateral hippocampi and the left thalamus.The ReHo in MDD patients decreased in bilateral superior and middle frontal gyri,left pallidum,bilateral putamina,left anterior cingulate cortex,whereas increased ReHo was found in right hippocampus and right thalamus.The SUV of bilateral superior,middle and inferior frontal gyri,bilateral superior and middle temporal gyri,bilateral putamina,left caudate,left pallidum,left anterior cingulate cortex,bilateral hippocampi and bilateral thalami were correlated with ReHo (r =0.51-0.83,all P＜0.05).However,no correlation was found between the SUV and ReHo in right caudate and anterior cingulate cortex (r=0.41,0.37; both P＞0.05).Conclusion There may be relative characteristic models of abnormal cerebral metabolism and cerebral dysfunction impairment in MDD patients,and the changes of cerebral regional glucose metabolism may be correlated with the changes of ReHo.

Objective To evaluate the protective effects of tea polyphenols against the destruction of melanocytes by CD8+ T cells from vitiligo patients.Methods Skin tissue was resected from the margin of vitiligo lesions followed by the isolation and culture of CD8+ T lymphocytes,and from the normal skin of vitiligo patients followed by the isolation and culture of melanocytes.Flow cytometry was carried out to evaluate the purity of CD8+ T cells.The melanocytes were cocultured with the CD8 + T cells at different ratios followed by the evaluation of killing effect of CD8+ T cells.Various concentrations (200 and 400 μg/ml) of tea polyphenols were added into the co-culture system of CD8+ T cells and melanocytes at a ratio of 5 ∶ 1 followed by an additional culture of 48 hours.Then,flow cytometry was performed to detect the apoptosis in melanocytes in the coculture system.Results CD8+ T lymphocytes were successfully obtained from the marginal area of vitiligo lesions with a purity of more than 90％,which highly expressed the antigens CD137 and CD69.The coculture with CD8+ T cells markedly accelerated the apoptosis in melanocytes,while the accelerative effect was inhibited by tea polyphenols of 200 and 400 μg/ml.Conclusions The CD8+ T cells infiltrating the edge of vitiligo lesions display a potential destructive effect on autologous melanocytes from vitiligo patients,and tea polyphenols have a protective effect against the destruction of melanocytes by CD8+ T cells.

Objective To investigate the infection sites,the offending species,diagnosis and prognosis of deep fungal infections (DFI) in patients with systemic lupus erythcmatosus (SLE).Methods Fifty-one patients with fungal infections in 1466 SLE patients admitted to Peking Union Medical College (PUMC) Hospital from 2000 to 2006 were reviewed retrospectively.Results Candida albicans was ranked the first pathogen,followed by ncoformans and Aspergillus species.The infection sites were lungs,cerebral meninges and blood in the order of prevalence.The overall mortality was 20%(10/51).Aspergillasis carried the highest mortality which couht be as high as 80%.Hypoproteinemia,multiple focus of fungal infections,Aspergillasis and fungemia might he the independent risk factor for mortality.Conclusion Candida albicans is the most frequent species of fungal infections in SLE patients.Iungs are the most prevalent location of infection.Earlier diagnosis is important.Special attention should be paid to aspergillasis.

Objective In order to improve the diagnosis accuracy , 18F-FDG PET/CT results of 169 cases of lung lesions were analyzed. Methods The data of 169 pathological diagnosed patients were collected. SPSS 18.0 was used for the data analysis. Results In 169 cases, 122 cases were proved malignant by patholog-ical diagnosis, in which 110 cases were correctly diagnosed by PET/CT. 47 cases were proved benign by patho-logical diagnosis, in which 15 cases were correctly diagnosed by PET/CT. The sensitivity was 90.2%, specificity was 31.9%, and the accuracy was 74.0%. Conclusion In order to improve the accuracy rate of PET/CT exam-ination and reduce the existence of false positive cases and false positive cases , we should estimate SUV (max) objectively and diagnose according to the size of the lesion , clinical history and laboratory results.

ObjectiveTo investigate the clinical application of tacrulimus (TAC, FK506) in children with primary nephrotic syndrome (NS). MethodsSixty-five primary NS children received routine or decreased-dosage glucocorticosteroid according to clinical NS types after hospitalization. At the same time, TAC was given orally with the dosage of 0.1 to 0.15 mg/kg, once every 12 hours, for 6 to 24 months. And the serum concentration of TAC was monitored during the course. ResultsAfter the treatment of TAC for 1 to 2 months, 65 patients were recovered with gradually reduced urinary protein, rapidly increased serum albumin, and improvement of cholesterol and triglycerides. Total remission rate was 83.1% and onset time was 7 to 54 days. Twelve cases experienced recurrence. Increased CD4, as well as 3/3 or 3/1 TAC genotype, indicated higher remission rate. Various pathological types had different remission rates or ratio, which were as follows: minimal change nephropathy (96.4%), mesangial proliferative glomendonephritis (90.0%), membranous nephropathy (2/3), membranous proliferative glomerulonephritis (3/5), focal segmental glomerulosclerosis (4/9). The patients would recover in the course of treatment under the conditions of TAC initial dose as 0.1 to 0.15 mg /kg per 12 hours and controlled serum concentration as 5 to 10 g/L. During the treatment, 12 cases appeared gastrointestinal symptoms, mainly as anorexia, nausea and vomiting, 1 abdominal pain, 2 headache, 1 tremor, 1 paresthesia, 3 insomnia, 4 transient increased Scr, 8 slightly increased NAG, 6 increased C3 and α-2 macroglobulin. The symptoms disappeared within one week or after stopping TAC. ConclusionsTAC is effective in primary NS children, even with abnormal liver function or tuberculosis infection. TAC can also be a substitute to cyclosporine A.

Objective To observe the clinical efficacy of cerebral palsy children with liver strong spleen weak syndrome treated with integrated traditional Chinese medicine therapy. Methods Eighty cerebral palsy children with liver strong spleen weak syndrome were divided into treatment group (40 cases) and control group (40 cases). Patients in control group were treated with conventional therapy (including exercise therapy, occupational therapy, guidance education, physical factors, and psychological therapy), and patients in treatment group were treated with integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) additionally. Three months were set for a course of treatment, and the whole treatment lasted for a total of four courses. TCM clinical symptoms were scored every six months, muscle tone (MAS), gross motor function (GMFM), and daily life activity ability (MBI) were evaluated every three months for both groups. Results There were significant differences in the total scores of TCM clinical symptom, MAS, GMFM, and MBI at different treatment time points in the two groups, compared with that before treatment (P<0.01). There were significant differences in the total scores of clinical symptom for Chinese medicine, MAS, GMFM, and MBI at different treatment time points for treatment group, compared with that of control group (P<0.05). Conclusion Integrated traditional Chinese medicine therapy (acupuncture and traditional Chinese medicine medicated bath) for cerebral palsy children on the basis of western medicine therapy can more effectively improve function and life quality of children patients.
