AIM: To investigate the association between cycloxygenase-2 (COX-2) expression and VEGF intervention as well as the inhibitory effect of Meloxicam on the cultured human pterygium fibroblasts (HPF).METHODS: Expression of COX-2 was measured by immunohistochemistry in the cultured HPF from twenty excised pterygium cases. Expression of COX-2 in HPF was measured by Western blot following the treatment of vascular endothelial growth factor (VEGF) at the different concentrations. In addition, the effect of Meloxicam on proliferation of HPF was studied by adding the different concentrations into the cultured HPF plates by Mono-nuclear cell direct cytotoxicity (MTT) reduction assay.RESULTS: COX-2 expression was present in the cultured HPF. The level of the expression increased following VEGF treatment. The proliferation of the cultured HPF decreased following addition of the different concentrations of Meloxicam (from 75μ mol/L to 300μ mol/L) and the magnitude of the inhibition was dose-time dependent.CONCLUSION: COX-2 levels in the cultured HPF werepositively associated with VEGF stimulation and Meloxicam was inhibitory to HPF proliferation.

BACKGROUND: It has been reported tbat there are rich expressions of serotonin transporter (5-HTT) in the cortical and limbic regions related to emotion and behavior in cerebrum. Regulation of the intensity and persistence of serotonergic nerve response can change the serotonergic neurotransmission, meanwhile, 5-HTT is also an important target for selective serotonin reuptake inhibitors (SSRIs).OBJECTIVE: To observe whether there is a correlation of 5-HTT gene polymorphism with plasma level of 5-HT and the clinical response of SSRIs in the population of Nanjing area.DESIGN: A case-control observation.SETTING: Department of Psychiatry, Brain Hospital of Nanjing Medical University.PARTICIPANTS: Totally 132 inpatients with depression in the Department of Psychiatry, Brain Hospital of Nanjing Medical University and 100 volunteer healthy blood donors were taken as the observational subjects between January 2001 and December 2003.METHODS: The genotype was analyzed with polymerase chain reaction (PCR) polymorphism analysis in the patients with depression and healthy subjects; plasma level of 5-HT was analyzed with high performance liquid chromatography-electrical chemistry detector (HPLC-ECD); and the clinical response to the antidepressants were assessed with Hamilton depression rating scale (HAMD).MAIN OUTCOME MEASURES: The analytical results of 5-HTT genotype frequency and allele frequency in both groups, and the relationship between 5-HTT genotype and plasma level of 5-HT before and after SSRIs treatment were observed.RESULTS: Blood samples were collected from all the 132 patients with depression and 100 normal healthy subjects, and they all finished the scale test and entered the analysis of results. ① There were no significant differences between the depression group and normal control group in the 5-HTT gene genotype frequencies (LL: 24.2%, LS: 44.7%, SS31.1%; LL:29.0%, LS: 47.0%, SS: 24.0%, x2=1.405 8, P ＞ 0.05) and allelefrequencies (L:46.59%, S: 53.41%; L: 52.5%, S: 47.5%, x2=0.696 2, P ＞ 0.05). ② The total score of HAMD had significant differences before treatment among the depressive patients of different genotypes (F=6.48, P=0.002 1). After 4-week treatment of SSRIs antidepressants, the total score of HAMD was significantly decreased, and there was significant difference in the decrease of score (F=3.38, P= 0.037). ③ The plasma level of 5-HT had significant differences before treatment among the depressive patients of different genotypes (F=5.38,P= 0.005 7). After 4-week treatment of SSRIs antidepressants, the plasma level of 5-HT was increased, and the increased level was significantly different among different genotypes (F=23.55, P ＜ 0.01).CONCLUSION: The 5-HTT polymorphism may be not associated with the attack of depression, but with the severity of depression and the clinical responses of SSRIs in the population of Nanjing area, and the genotype in this area may become a reference index for the realization of individualized treatment in patients with depression.

BACKGROUND: Monoamine hypothesis has been demonstrated by researches. However, the correlation between the metabolite of plasma monoamine neurotransmitter and anti-depression treatment in patients with depression has less been reported.OBJECTIVE: To study the effect of different drugs on metabolite of plaama monoamine neurotransmitter, and the correlation between the metabolite of plasma monoamine neurotransmitter and anti-depression treatment in patients with depression.DESIGN: Case controlled study.SETTING: Neurological Department and Brain Institute of Nanjing Medical University.PARTICIPANTS: Forty patients with depression hospitalized in Nanjing Brain Hospital (depression group) were diagnosed with the second revised edition of China classification of mental diseases(CCMD-2) and the tenth edition of International classification of diseases. And the total score of Hanmilton rating scale for depression(HAMD) was more than 17. Healthy voluntary blood donators in the control group were from Nanjing Municipal Central Blood Station( n = 20).INTERVENTIONS: Antidepressant was used in the depression for 4 weeks: fluoxetine 20 mg per day; 5-serotonin selective reuptake inhibitor (SSRI) paroxetine 20 mg per day; venlafaxime 50- 100 mg per day;5-serotonin and morepinephrine selective reuptake inhibitor(SNRI) fluvoxamine 50-100 mg per day. High performance liquid chromatograpy(HPLC)was used to measure the level of metabolite of plasma monoamine neurotransmitter in patients with depression before and 42 week after treatment, and the HAMD was used to evaluate clinical effect of the patients.MAIN OUTCOME MEASURES: The levels of metabolites of plasma monoamine neurotransmitters in patients with depression: 5-hydroxyindoleace tic acid(5-HIAA), 3-methoxy-4-hydroxyphenylglycol(MHPG) and homovani llic acid(HVA) were measured before and 4th week after treatment.RESULTS: The levels of 5-HIAA, MHPG and HVA of the metabolites of plasma monoamine neurotransmitters in patients with depression before treatment [ (20.3±14.6), (124.8±103.6), (54.7±32.1) μg/L] were all lower than those in the normal control group[ (39.5±28.4), (334.5 ±107.3), (88.5±37.2) μg/L], with statistically significant differences (P＜0.05). After SSRI treatment, the 5-HIAA content[ (37.1±21.9)μg/L]was significantly increased as compared with that before treatment, whose difference indicated significant meaning ( P＜0.05), but the differences in MHPG and HVA had no significant meaning as compared with those before treatment(P＞0.05) . After SNRI treatment, 5-HIAA and MHPG contents [(35.4±25.2 ), (291.2±120.4) μg/L] both were significantly increased, which indicated significant difference as compared with those before treatment( P＜0.05); but HVA level had no significant changes.CONCLUSION:'The peripheral neurotransmitter metabolites in plasma can reflect their states in brain. The change of neurotransmitter metabolite in plasma can be regarded as an important reference index for the evaluation of depression.

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.

METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.

RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).

CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.
