RESUMO
OBJECTIVE: To explore the levels of adiponectin (APN), interleukin-1ß (IL-1ß), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in first episode drug naÑve schizophrenics and further examine the role of adipocytokines in schizophrenia. METHODS: Ninety-six normal weight schizophrenics and 22 overweight/obese ones from First Affiliated Hospital, Zhengzhou University and 60 healthy controls were enrolled. Serum levels of IL-1ß, IL-6, TNF-α and APN were measured with enzyme linked immunosorbent assay (ELISA). RESULTS: Serum levels of IL-1ß, IL-6 and TNF-α in normal weight schizophrenics (54 ± 13, 34 ± 12, 48 ± 18) pg/ml and overweight/obese schizophrenics (71 ± 21, 40 ± 12, 53 ± 18) pg/ml were significantly higher than those in the controls (23 ± 16, 16 ± 7, 32 ± 15) pg/ml (P < 0.05). Serum levels of IL-1ß and IL-6 in overweight/obese schizophrenics were significantly higher than those in normal weight schizophrenics (P < 0.05). Serum level of adiponectin in normal weight schizophrenics was significantly higher than that in control group [(12 ± 4) vs (9 ± 4) pg/ml, P < 0.05]. CONCLUSION: The serum levels of APN, IL-1ß, IL-6 and TNF-α increase in first episode drug naÑve schizophrenics. It suggests that an inflammatory response mediated by adipocytokines. APN may play a pro-inflammatory role in schizophrenia.

OBJECTIVE: To explore the changes in serum protein levels of schizophrenics before and after treatment of risperidone and identify the potential markers of diagnosis, treatment and drug side effects of schizophrenia. METHODS: Eighty first-episode schizophrenics without other concurrent diseases and with positive and negative symptom scale (PANSS) score greater than or equal to 60 were recruited. And 15 of them were measured by proteomics. Different serum levels of proteins were obtained from these patients and were separated by two-dimensional electrophoresis (2-DE) before and after a single risperidone treatment for 8 weeks. These proteins were then identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and peptide mass fingerprinting. Enzyme-linked immunosorbent assay (ELISA) was used to verify the results. RESULTS: Almost 1400 spots were detected by 2-DE in each gel. Of these proteins, 23 protein spots showed significant differences in abundance before and after risperidone treatment. After MALDI-TOF peptide mass fingerprinting, 9 up-regulated proteins and 8 down-regulated proteins were validated after treatment. Of these proteins, the schizophrenics showed a significantly higher content of apolipoprotein A-1 (APOA-1) than those before treatment and haptoglobin (HP) protein was down-regulated after treatment. The results of ELISA were parallel with those of proteomic (P < 0.01). CONCLUSION: The serum proteins correlated with blood glucose and lipid metabolism are altered in schizophrenia after treatment of risperidone. A clinician should monitor the side effects of antipsychotic drugs according to the changes of serum proteins.

Little research has been done on the effects of hyperbaric oxygen (HBO) on depression and anxiety after spinal cord injury (SCI). The aim of this study was to investigate the effects of HBO on psychological problems and never function, especially on depression and anxiety in the patients with incomplete SCI (ISCI).Sixty patients with ISCI combined with depression and anxiety were randomly divided into HBO group (20 cases), psychotherapy group (20 cases), and conventional rehabilitation control group (20 cases). All patients received routine rehabilitation therapy. However, in HBO group and psychotherapy group, patients also received HBO and psychotherapy, respectively. These therapies lasted for a total of 8 weeks (once a day and 6 days per week). Before and after 8 weeks of treatment, depression and anxiety, nerve function, and activities of daily living were, respectively, evaluated according to Hamilton Depression (HAMD) scale, Hamilton Anxiety (HAMA) scale, American Spinal Injury Association score, and functional independence measure score in all patients.After 8 weeks of treatment, HAMD score was significantly lower in both HBO group and psychotherapy group than in control group (all Pâ<â.05), but there was no statistical difference in HAMD score between HBO group and psychotherapy group (Pâ>â.05). HAMA score was significantly lower in HBO group than in control group (Pâ<â.05), but there was no statistical difference in HAMA score between HBO group and psychotherapy group, and between psychotherapy group and control group (all Pâ>â.05). After 8 weeks of treatment, American Spinal Injury Association and functional independence measure scores were significantly higher in HBO group than in both psychological and control groups, and also higher in psychotherapy group than in control group (all Pâ<â.05).The effects of HBO on depression and anxiety are similar to that of psychotherapy. HBO can significantly improve nerve function and activities of daily living in the patients with ISCI, which either psychotherapy or routine rehabilitation therapy can not substitute.
