OBJECTIVE:To study the protective effects of sodium magnesium fructose diphosphate(FDPM)on brain damage induced by ischemiareperfusion in rats.METHODS:Rats were subjected to cerebral ischemia-reperfusion induced by inserting a nylon thread into internal carotid artery to block the origin of middle cerebral artery and removing the thread for recirculation.After1h ischemia,FDPM(400mg/kg),fructose-1,6-diphosphate(FDP,400mg/kg)or magnesium sulfate(MgSO 4 ,30mg/kg)was administrated10min after the onset of ischemia.Neurological scale was scored after1h ischemia and after2h,5h and23h recirculation,and infarction area,MDA content and histopathological change of brain tissue were studied after1h ischemia and after23h recirculation.RESULTS:Compared with model group,400mg/kg FDPM decreased neurological scale,diminished infarction area,reduced MDA content and relieved pathomorphological changes of brain tissue subjected to ischemia-reperfusion in rats.These effects were more powerful than those of FDP(400mg/kg)or MgSO 4 (30mg/kg).CONCL_ USION:FDPM(400mg/kg)could markedly prevent rats from brain damage after cerebral ischemia-reperfusion,and its effects were more potent than those of FDP(400mg/kg)or MgSO 4 (30mg/kg).

Background: It is reported that 30% to 80% schizophrenia patients suffered from hypersalivation when taking clozapine. Some investigations of the use of formulas of traditional Chinese medicine (TCM) to treat clozapine-induced hypersalivation suggested their potential treatment effects. In these formulas, Suoquan Pill (SQP) and Wuling Powder (WLP) were suggested to have therapeutic effects in improving clozapine-induced hypersalivation. Methods and design: A prospective, double-blind, randomized, placebo-controlled study will be conducted to test the therapeutic effects of SQP and WLP in relieving hypersalivation in patients taking clozapine. A total of 45 patients will be enrolled into this study with 15 in each treatment group. Patients will receive medication according to their assigned group. Either SQP 10 g per oral dose twice daily, WLP 10 g per oral dose twice daily or placebo powder 10 g per oral dose twice daily will be prescribed to the patients for 8 weeks. The Drooling Severity Scale, Nocturnal Hypersalivation Rating Scale and sialoscintigraphy will be used as the primary outcome measures; the Clinical Global Impressions Severity, the Positive and Negative Syndrome Scale, the Abnormal Involuntary Movement Scale, the Simpson-Angus Scale and the TCM constitutional scale will be used as the secondary outcome measures Discussion: It is hypothesized that SQP and WLP will have a beneficial effect in controlling clozapine-induced hypersalivation symptoms. It may also improve the life quality of psychotic patients by improving their mental status. Trial registration: ClinicalTrials.gov (Identifier: NCT01045720).

Objective To establish a sensitive,valid and rapid high performance liquid chromatography-trap mass spectrometry (HPLC-MS) method for determining carbocisteine concentration in human plasma. Methods Plasma samples were pretreated by 100 mL/L perchloric acid to remove the interference protein. The supernatant was separated by reverse phase HPLC,electrospray MS was used to detect carbocisteine in plasma samples,and selective ion method of multiple reaction modes was used to determine the concentration of carbocisteine. Results The limit of detection was 0.01 ?g/mL and the linear range was 0.2-200.0 ?g/mL. The recovery rate was within the range of 89.2%-105.6%. Conclusion The proposed method could be used to determine carbocisteine in biological samples.
