Immunological alterations and changes in neurotransmission are considered to be crucial in the pathological process of depression. An immune activation including increased production of proinflammatory cytokines has repeatedly been described in depression, which shines a clue for new anti-depression therapy. Immune activation will lead to depression through serotonin and glutamate systems. This paper is attempted to review the immune mediated alterations on serotonin and glutamate systems.

Objective To evaluate 64-MSCT virtual endoscopy in the examination method,displaying ability and clinical application of colon lesions.Methods Compared the results of 49 cases of patients examined with 64-MSCT with that got from Coloscopy,and statistical analysis was conducted.Results A total of 19 cases of adenocarcinoma and 2 cases of colonic diverticula as well as 44 cases of adenomatous polyp were detected.The display rate of polyps was 100％ in which was larger than 10mm,73％ in which was range of 5 ～ 10mm in size and 50％ in which was smaller than 5mm.Conclusion As an relatively noninvasive examination method,64-MSCT virtual endoscopy is concordant with onventional colonoscopy in the aspect of detectable rate and revealing the lesion morphologic and can be used as an important examination measure in the diagnosis for colonic diseases.

Objective To compare the efficacy of three solutions used in the patients who suffered chronic obstructive pulmonary diseases (COPD ) when combined with oral fungal infection,and to find the most suitable one. Methods Using randomized controlled trial method, 98 patients who suffered COPD complicated with fungal infection were randomly divided into three groups. Method 1, using 0.5% povidone for the oral care. Method 2, making 200 million U of nystatin powder dissolved in 2.5% NaHCO3 for the oral care.Method 3, gave oral care with 2.5% NaHCO3 first, then put 200 million U of nystatin powder into 20 ml glycerol and covered the oral spots with them. Three groups were observed in the effect of oral fungal infection and the feedback from patients and nurses. Results In the analysis of the white spots sharply disappeared or pharyngeal swab smear turned negative, method 1 and method 3 had no statistical difference, P>0.05, but method 2 and method 3 had statistical significance, t=3.892, P <0.01; the three groups had no significant difference of feedback from the patients’ oral comfort, P >0.05. The time made solution of method 1 occupied 41.7% of method 3, and the time made solution of method 2 occupied 54.4%of method 3, while there was no statistical significance in total time of three groups (P>0.05). Conclusions The oral care with 0.5% povidone had good effect on the patients who suffered COPD complicated with oral fungal infection,with good comfort,and most nurses saving time. Nystatin powder dissolved in 2.5% NaHCO3 worked later than nystatin powder dissolved in glycerol.

Objective To explore the association between the genetic polymorphism of CYP3A4,CYP2D6 and response to methadone maintenance treatment(MMT)among heroin-dependent patients.Methods Patients undergoing MMT in 6 MMT clinics were randomly selected,information about general socia-demographic characteristics,drug abuse history,and MMT data of patients were collected,genotypes of peripheral blood CYP3A4 and CYP2D6 polymorphic loci were detected.Results A total of 820 patients were enrolled in the study,210 cases were with good response and 610 cases with poor response to MMT.Difference in age between different response groups was statistically significant(P<0.05).Distribution of genotype frequency and allele frequency of CYP3A4 rs2242480 and CYP2D6 rs16947 between good response and poor response groups was not significantly different(both P>0.05).Conclusion The association between CYP3A4 rs2242480,CYP2D6 rs16947 and response to MMT has not yet found in heroin-dependent patients.

Objective To explore the role of histone H3 acetylation modification of brain derived neurotrophic factor (BDNF) in the pathogenesis of Alzheimer's disease (AD).Methods 2 months and 8 months SAMP8 mice were used as AD model.Morris water maze was used to detect the impairment of learning and memory.Western blot was used to detect BDNF protein expression in the hippocampus,and chromatin immunoprecipitation (CHIP) was applied to study the changes of histone H3 acetylation in different BDNF promoters.Results The results of water maze test showed that the time across the target quadrant in 8 months SAMP8 mice(0.9±0.4) was significant declined compared with that of 2 months SAMP8 mice(3.7 ± ±0.9) and 8 months SAMR1 mice (3.3±0.6)(all P＜0.05).Meanwhile,compared with 2 months SAMP8 mice ((23.9±4.0) s) and 8 months SAMR1 mice ((21.5± 2.3) s),target quadrant time in the 8 months SAMP8 mice((11.7±2.8) s) was also significantly reduced(both P＜0.05).The western blot showed the expression of BDNF in the hippocampus of 8 months SAMP8 mice was significantly decreased compared with that of 2 months SAMP8 mice and 8 months SAMR1 mice(P＜0.05).Lastly,CHIP assays showed that histone H3 acetylation of BDNF exon Ⅳ and Ⅵ in the hippocampus of 8 months SAMP8 mice were remarkably decreased(P＜0.05) compared with that of 2 months SAMP8 mice and 8 months SAMR1 mice.There was no significant change of histone H3 acetylation of BDNF exon Ⅰ and Ⅲ among all groups(P＞0.05).Conclusion Histone H3 acetylation of BDNF exon Ⅳ and Ⅵ is reduced during the development of AD,which may be the mechanism underlying the impairment of learning and memory in AD.

Objective To investigate the role of bladder interstitial cells of Cajal(ICCs) in regulating the excitability of detrusor myocytes.Methods 1)Ultrastructural connection between ICCs and detrusor myocytes was detected by transmission electron microscope(TEM).2) Fluorescence redistribution after photobleaching(FRAP) was carried out to detect the intercellular communication between detrusor myocytes and its neighboring ICCs.Results 1)Gap junction between the 2 kinds of cells was confirmed by TEM.2)After target detrusor myocyte was photobleached,fluorescence intensity in detrusor myocytes was recovered gradually.In the meantime,fluorescence intensity in the ICCs neighboring to the target detrusor myocyte was decreased.This indicates a signal transmission from the neighboring ICCs to the target detrusor myocyte.Conclusion Structural connection is seen between ICCs and detrusor myocytes.Excitability signals might be transferred from ICCs to detrusor myocyte.

Objective To study the clinic effect and safety of MEAD chemotherapy regimen for adult patients with relapsed or refractory acute lymphocyte leukemia. Methods Between July 2006 and July 2009,twenty-two adult patients with relapsed or refractory acute lymphocyte leukemia received MEAD regimen (mitoxantrone 6 mg/d dl-3 iv drip,cytarabine 100 mg/d dl-5 iv drip,etoposide 100 mg/d dl-5 iv drip,dexmethasone 10 mg/d dl-8 iv drip). Results The complete remission (CR) rate of adult patients with relapsed or refractory acute lymphocyte leukemia was 31.8 %,the partial remission(PR) rate was 22.7 % and the overall response (OR) rate 54.5 %. The cumulitive CR rate was 50.0 %,and the PR rate 40.9 % after two times MEAD chemotherapy regimen. The main adverse effect was different level of myelosuppression,and other toxicity of vital organ was mild. Conclusion MEAD regimen is effective and can be tolerated for adult patients with relapsed or refractory acute lymphocyte leukemia,and its side effect is mild.

Objective To investigate correlation between aspirin resistance(AR) and inflammatory factors. Methods One hundred and ten patients with coronary heart disease took aspirin 0.1 mg/d for 14 days.It was detected platelet aggregation function induced with adenosine disphosphate (ADP) and arachidonic acid (AA), and investigated correlation between AR and inflammatory factors. Interleukin-1? (IL-1?),interleukin-6 (IL-6) and high sensitive C-reaction protein (hs-CRP) levels. Results IL-6 level of patients with AR was significantly higher than that of aspirin sensitive (AS) patients. The other two index were not different between the two groups. Conclusion IL-6 levels could be used as predictor.
