OBJECTIVETo investigate the effect of aluminum chloride on dissociated Ca(2+) in hippocampus neuron cells in mice and the relationship to the learning and memory.

METHODSMale ICR mice in the three intoxicated groups were administered with the double distilled water containing AlCl(3) (10, 50, 300 mg.kg(-1).d(-1)) while those in the control group were administered with the double distilled water for 100 days. The methods of behavior toxicology such as Morris swim maze were used for studying the effect of aluminum chloride on the changes of learning and memory in mice. With calcium sensitive fluorescence indicator Fura-2 as the fluorescent probe, the influence of the subchronic exposure to Al on the dissociated Ca(2+) in hippocampus neuron cells was observed.

RESULTSThe dissociated Ca(2+) in hippocampus neuron cells in the middle dosage group and the high dosage group [(412.25 +/- 53.20), (467.37 +/- 32.85) times] was lower than those in the control group [(293.91 +/- 32.21) times] respectively (P < 0.01), and correlated positively with the dose and dissociated Ca(2+) (r = 0.861, P < 0.01). Compared with the control group, the latent period was lengthened (P < 0.05) in the middle dosage and the high dosage group.

CONCLUSIONThe subchronic exposure to AlCl(3) in mice affects the dissociated Ca(2+) in hippocampus neuron cells. The increase of dissociated Ca(2+) in hippocampus neuron cells may be correlated with the disfunction of cognition in the aluminium intoxicated mice.

OBJECTIVETo investigate the factors upgrading the International Society of Urological Pathology (ISUP) Gleason score using the specimens from preoperative prostatic biopsy and radical prostatectomy.

METHODSA total of 164 patients diagnosed with prostate cancer by biopsy underwent radical prostatectomy. We retrospectively analyzed their age, prostate volume, preoperative PSA level, PSA density (PSAD) , the time interval between biopsy and surgery, the number of positive punctures, positive surgical margin, seminal vesicle invasion, lymphatic invasion, and Gleason scores from biopsy and prostatectomy. We also determined the predictors of Gleason score upgrading by logistic regression analysis.

RESULTSOf the 164 cases analyzed, 95 (57.93% ) showed a consistency between the Gleason score of preoperative prostatic biopsy and that after radical prostatectomy, 55 (33.54% ) increased and 14 (8.52%) decreased after prostatectomy as compared with preoperative biopsy. The prostate volume (P < 0.01) and biopsy score (P < 0.05) were independent predictors of Gleason score upgrading. The risk of Gleason score upgrading was 27 times higher in the patients with the prostate volume ≤ 25 ml and 9 times higher in the 25-40 ml group than in the > 60 ml group (P < 0.05).

CONCLUSIONLow Gleason score of biopsy (≤ 6) and small prostate volume (≤ 40 ml) may be the predictors of Gleason score upgrading after radical prostatectomy.

OBJECTIVETo investigate the effect of herba schizonepetae volatile oil (STO) on the activity of 5-lipoxygenase (5-LO), so as to elucidate its mechanisms of anti-inflammatory action which is related to the arachidonic acid (AA) metabolism.

METHODThoracic cavity leukocytes from the pleurisy model rat induced by injecting 1%-carrageenan into the pleural cavity were collected. Then 0. 4 mL cell suspension including 2 x 10(7) cells per millilitre were used as the reaction system in vitro. STO in different concentrations (final concentration 0.011, 0.022, 0.043, 0.087, 0.179, 0.255, 0.364 g x L(-1)), zileuton (final concentration 0.625 x 10(-3) g x L(-1)), and DMSO in the same volume were added into the reaction tube respectively. The reaction tubes were incubated at 37 degrees C for 20 min and CaCl2 (final concentration 2 mmol x L(-1)), MgCl2 (final concentration 0.5 mmol x L(-1)), exogenous AA (final concentration 200 micromol x L(-1)) and A23187 (final concentration 5 micromol x L(-1)) were added in turns during this period. The reaction tubes were mixed and continuously incubated at 37 degrees C for 30 min. After terminating reaction by adding methanol, the metabolites of 5-LO, leukotriene B4 (LTB4) and 5-hydroxy-6, 8, 11, 14-eicosatetraenoic acid (5-HETE), were extracted, separated and detected by means of RP-HPLC.

RESULTCompared with control group, STO significantly inhibited the biosynthesis of LTB4 and 5-HETE at final concentration between 0. 022 g x L(-1) and 0.364 g x L(-1) (P < 0.05 or 0.001) in dose dependence manner, and its IC50 value was 0.124 g x L(-1) and 0.142 g x L(-1) for LTB4 and 5-HETE, respectively.

CONCLUSIONSTO can inhibited the activity of 5-LO, which is an important enzyme of AA metabolism, in rat thoracic cavity leukocytes in a dose-dependent manner in vitro. It is suggested that the mechanism of anti-inflammatory action of STO is related to its inhibiting the activity of 5-LO and decreasing the level of major inflammatory mediators LTB4.

Hepatitis B virus (HBV)-induced liver failure is an emergent liver disease leading to high mortality. The severity of liver failure may be reflected by the profile of some metabolites. This study assessed the potential of using metabolites as biomarkers for liver failure by identifying metabolites with good discriminative performance for its phenotype. The serum samples from 24 HBV-induced liver failure patients and 23 healthy volunteers were collected and analyzed by gas chromatography-mass spectrometry (GC-MS) to generate metabolite profiles. The 24 patients were further grouped into two classes according to the severity of liver failure. Twenty-five commensal peaks in all metabolite profiles were extracted, and the relative area values of these peaks were used as features for each sample. Three algorithms, F-test, k-nearest neighbor (KNN) and fuzzy support vector machine (FSVM) combined with exhaustive search (ES), were employed to identify a subset of metabolites (biomarkers) that best predict liver failure. Based on the achieved experimental dataset, 93.62% predictive accuracy by 6 features was selected with FSVM-ES and three key metabolites, glyceric acid, cis-aconitic acid and citric acid, are identified as potential diagnostic biomarkers.
