Effects of dendritic cell-activated and cytokine-induced killer cell therapy on 22 children with acute myeloid leukemia after chemotherapy.

The efficiency of dendritic cell-activated and cytokine-induced killer cell (DC-CIK) therapy on children with acute myeloid leukemia (AML) after chemotherapy was investigated. Mononuclear cells were collected from children achieving complete remission after chemotherapy, cultured in vitro and transfused back into the same patient. Interleukin-2 (IL-2) was injected subcutaneously every other day 10 times at the dose of 1 × 10(6) units.

Beneficial effects of EGb761 and vitamin E on haloperidol-induced vacuous chewing movements in rats: Possible involvement of S100B mechanisms.

Tardive dyskinesia (TD) is a serious side effect induced by the long-term administration of typical antipsychotics. The pathophysiology of TD remains unclear, but experimental evidence suggests that neurodegeneration caused by free radicals may play an important role in TD development. S100B is considered a potential biomarker of structural neural and glial damage.

The effects of high-frequency repetitive transcranial magnetic stimulation (rTMS) on negative symptoms of schizophrenia and the follow-up study.

In this double-blind, randomized controlled study, we assessed the therapeutic effects of high-frequency left dorsolateral prefrontal cortex (DLPFC) repetitive transcranial magnetic stimulation (rTMS) on negative symptoms of schizophrenia. For the study, 117 patients with prominent negative symptoms were randomized to a 20-day course of either active rTMS applied to the left DLPFC (n = 78) or sham rTMS (n = 39). The primary outcome measures were the Positive and Negative Symptom Scale (PANSS) and the Scale for the Assessment of Negative Symptoms (SANS).

Extract of Ginkgo biloba is equivalent to vitamin E in attenuating and preventing vacuous chewing movements in a rat model of tardive dyskinesia.

Free radical-mediated abnormalities may contribute toward the pathogenesis of tardive dyskinesia (TD). Many studies have reported the protective antioxidant and free radical-scavenging activities of extract of Ginkgo biloba (EGb761) against free radical-induced cell damage and dysfunction. This study aimed to compare the efficacy of EGb761 with that of vitamin E for the prevention and treatment of TD in a rat model.

Impaired prepulse inhibition of acoustic startle in Chinese patients with first-episode, medication-naïve schizophrenia.

Background: Patients with schizophrenia have prominent abnormality in information processing that can be observed by measures of prepulse inhibition (PPI) of acoustic startle reflex and PPI deficits have been considered as a candidate endophenotypic marker of schizophrenia. However, there has been little information on PPI and related measures in Chinese patients with schizophrenia. The research was to explore the deficits of acoustic startle reflex that might exist in Chinese patients with schizophrenia.

Ventral medial prefrontal functional connectivity and emotion regulation in chronic schizophrenia: a pilot study.

People with schizophrenia exhibit impaired social cognitive functions, particularly emotion regulation. Abnormal activations of the ventral medial prefrontal cortex (vMPFC) during emotional tasks have been demonstrated in schizophrenia, suggesting its important role in emotion processing in patients. We used the resting-state functional connectivity approach, setting a functionally relevant region, the vMPFC, as a seed region to examine the intrinsic functional interactions and communication between the vMPFC and other brain regions in schizophrenic patients.

Infusions of recipient-derived cytokine-induced killer cells of donor origin eradicated residual disease in a relapsed leukemia patient after allo-hematopoietic stem cell transplantation.

A female patient diagnosed with acute myelocytic leukemia M5a (AML-M5a) relapsed 986 days after her allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from an unrelated male donor with matched human leukocyte antigen (HLA). Three re-induction chemotherapies were administered, and partial remission was achieved. The patient was given repetitive infusion of cytokine-induced killer (CIK) cells expanded from recipient peripheral mononuclear cells of full donor chimerism due to loss of contact of quondam donor for donor lymphocyte infusion (DLI) and rejection of second transplantation.

Effects of risperidone and haloperidol on superoxide dismutase and nitric oxide in schizophrenia.

Oxidative stress may be involved in the pathophysiology of schizophrenia. No double-blind study has compared the effects of typical and atypical antipsychotics on both antioxidant enzyme activity and nitric oxide (NO) levels in schizophrenic patients. Seventy-eight inpatients with chronic schizophrenia were randomly assigned to 12 weeks of treatment with 6 mg/day of risperidone or 20 mg/day of haloperidol using a double-blind design.

[Comparisons of clinical features of chronic aplastic anemia and myelodysplastic syndrome in children].

Objective: This study compared the differences in clinical features between chronic aplastic anemia (CAA) and myelodysplastic syndrome (MDS) in children in order to provide a basis for the differential diagnosis of the two diseases.

Methods: A retrospective study of 23 cases of CAA and 9 cases of MDS from September 2007 to September 2010 was performed. The clinical data including routine blood test results, reticulocyte counts, serum lactate dehydrogenase level, serum ferritin level, cytological examination of bone marrow, bone marrow CD34+ cell counts, bone marrow chromosome and FISH test results were compared between the CAA and MDS groups.

Dysfunction in different phases of working memory in schizophrenia: evidence from ERP recordings.

The present study combined a time-locked paradigm and high-time-resolution event-related potential (ERP) recordings to examine different phases of working memory, including early visual processing and late memory-related processes of encoding, maintenance, and retrieval, in 67 adults with schizophrenia and 46 healthy controls. Alterations in ERP components were correlated with task performance. Patients performed significantly worse in the working memory task than healthy subjects, although all subjects' accuracy exceeded 80%.

[Expression and clinical significance of COX-2 and BCL-2 in distal transitional mucosa adjacent to rectal carcinoma].

Objective: To investigate the expression of COX-2 and BCL-2 in transitional mucosa adjacent to rectal carcinoma, and to determine whether precursor event exists in the transitional mucosa.

Methods: Mucin histochemical method (HID/AB) was used to determine the distal mucosa 2 cm away from rectal carcinoma in 54 patients with rectal cancer. Immunohistochemical method was employed to detect the expression of BCL-2 and COX-2 in the rectal cancer specimen, transitional mucosa (TM), non-transitional mucosa (NTM), and 20 cases of normal rectal mucosa.

Extract of Ginkgo biloba treatment for tardive dyskinesia in schizophrenia: a randomized, double-blind, placebo-controlled trial.

Objective: Free radicals may be involved in the pathogenesis of tardive dyskinesia (TD). Extract of Ginkgo biloba (EGb) is a potent antioxidant possessing free radical-scavenging activities. The aim of the study was to evaluate the efficacy of EGb-761, a standardized extract given in capsule form, in treating TD in schizophrenia patients.

[The establishment of an animal model of gut-brain interaction in irritable bowel syndrome for the evaluation of visceral sensation, motility and psychological behavior.].

Objective: To develop a gut-brain interaction animal model of IBS which combines multiple factors including behavior, visceral sensation and motility.

Methods: Setting up a multifactor interactional animal model (chronic acute combining stress model, CACS) based on a chronic unpredictable mild stress model of depression (CUMS) while combined with wrap restraint stress (WRS), changes of some indexes were recorded including motility (granules of defecating, time of defecating), visceral sensitivity (spontaneous contraction of abdominal striated muscles) and behavior/mind (sucrose consumption, body weight). G protein subunits were measured by Western blot in both hippocampus and prefrontal cortex simultaneously.

[Therapeutic effects of a combination of high-dose immunoglobulin and cyclosporine A in children with aplastic anemia].

Objective: To evaluate the therapeutic effects of a combined immunotherapy, high-dose immunoglobulin (HDIG) plus cyclosporine A (CsA) plus prednisone (P), in children with aplastic anemia (AA) and to explore the association of peripheral blood lymphocyte subsets, peripheral blood cells and marrow CD34+ cells with therapeutic effects in AA.

Methods: The clinical data of 46 children with AA and who received the combined immunotherapy of HDIG + CsA + P were retrospectively studied.

Results: Of the 46 children with AA, 31 (67.

Superoxide dismutase and cytokines in chronic patients with schizophrenia: association with psychopathology and response to antipsychotics.

Objective: Both schizophrenia and oxidative stress have been associated with immune system abnormalities in interleukin-2 and -6 (IL-2; IL-6) and increases in superoxide dismutase (SOD) activity. These abnormalities may improve during antipsychotic drug treatment that reduces symptoms in schizophrenic patients.

Materials And Methods: Subjects included 30 healthy controls (HC) and 78 schizophrenic (SCH) in-patients who were randomly assigned to 12 weeks of double-blind treatment with risperidone 6 mg/day or haloperidol 20 mg/day.

Therapeutic effectiveness of the ALL-XH-99 protocol for childhood acute lymphoblastic leukemia.

Objective: The ALL-XH-99 protocol for the treatment of childhood acute lymphoblastic leukemia (ALL) has been performed in the Union Hospital for 10 years. This study aimed to evaluate the therapeutic effectiveness of the protocol for childhood ALL and to investigate the prognostic factors for childhood ALL.

Methods: This is a retrospective study.

BDNF levels and genotype are associated with antipsychotic-induced weight gain in patients with chronic schizophrenia.

Recent evidence suggests that centrally released brain-derived neurotrophic factor (BDNF) modulates eating behavior and metabolism that is responsible for body weight fluctuation. BDNF also may play an important role in the therapeutic action of antipsychotic medications. We investigated whether the Val66Met polymorphism of the BDNF gene affected weight gain after long-term antipsychotic treatment in schizophrenia.

[Relationship between tardive dyskinesia and the polymorphism of superoxide dismutase val9Ala and efficacy of Chaihu Taoren Capsules on it].

Objective: To investigate the relationship between efficacy of Chaihu Taoren Decoction (CTD) and the polymorphism of valine-alanine missense mutation of 9th codan (Val9Ala, T1183C) of superoxide dismutase (SOD) in patients with tardive dyskinesia (TD).

Methods: Severity of TD was assessed by abnormal involuntary movement scale (AIMS), and the psychologic symptoms were rated by the positive and negative symptoms scale (PANSS). The sample size consisted of 119 patients with TD assigned to the TD group, 129 patients of chronic schizophrenia with the general condition matched strictly with that of the enrolled TD patients assigned to the non-TD group, and 148 healthy persons assigned to the normal group.

Disrupted antioxidant enzyme activity and elevated lipid peroxidation products in schizophrenic patients with tardive dyskinesia.

Background: Free radical-mediated pathology has been implicated in the development of tardive dyskinesia (TD). Antioxidant defense system alterations and increased lipid peroxidation have been postulated as a possible mechanism for neuronal damage associated with TD. However, the relationship between antioxidant enzymes, lipid peroxidation products, and the severity of TD symptoms has not been determined within a single patient group.
