Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising anti-cancer agent. However, emergence of drug resistance limits its potential use. Plumbagin is a natural quinonoid compound isolated from plant. In this study, induced apoptosis effect of the combined treatment with plumbagin and TRAIL on human melanoma A375 cell line was examined and possible mechanism was investigated. The cells were divided into four groups: control group, plumbagin group (plumbagin, 5 or 10 mumol/L), TRAIL group (TRAIL, 30 ng/mL) and plumbagin+TRAIL group (combined treatment group). The apoptosis, and the expression of DR4 and DR5 were detected by flow cytometry. The activities of caspase-8 and caspase-3 were determined by colorimetric assay. The results showed that the apoptosis rate was 8.3% in TRAIL group, 10.35%-16.94% in plumbagin group and 52.39%-65.39% in combined treatment group, respectively, with the difference being significant between combined treatment group and plumbagin or TRAIL group (P<0.05 for each). Moreover, plumbagin alone could markedly up-regulate DR5 mRNA and protein expression, and slightly increase DR4 mRNA and protein expression. Treatment of human melanoma A375 cells with plumbagin resulted in the activation of Caspase-3, but not Caspase-8. These results suggest that plumbagin might be useful for TRAIL-based treatment for melanoma.

OBJECTIVETo study the short- and long-term effects of multi-glycosides of tripterygium wilfordii (GTWon) the histological structures of testes in pubertal rats and possible mechanisms.

METHODSForty-eight 5-week-old male Sprague-Dawley rats were randomly intragastrically administered with low-does GTW(6 g/kg daily)and high-does GTW (12 mg/kg daily) or 1% sodium carboxymethylcellulose (6 mL/kg, control group) for four weeks. The testes were sampled for detecting histological structures and c-kit expression by immunohistochemistry 24 hrs and four weeks after drug discontinuance.

RESULTSThe number of spermatogenic cells and the expression of c-kit in testes were reduced in the two GTW treatment groups 24 hrs and 4 weeks after drug discontinuance compared with those in the control group(P<0.05). Four weeks after drug discontinuance atrophy and interstitial edema of seminiferous epitheliumin in testes were observed, and the testis weight and the expression of c-kit in testes were reduced in the high-does GTW group compared with those in the control group (P<0.01). There were no significant differences in the parameters observed between the low-dose GTW and the control group 4 weeks after drug discontinuance.

CONCLUSIONSGTW has adverse effects on testes in a dose-dependent manner in puberty rats. Low-dose GTW may cause reversible short-term injuries to testis tissues. The damage of the interstitial tissue of testes induced by high-dose GTW may be one of the causes of long-term injuries of testes.

Objective To explore the differences in the strength of the nodes in the brain white matter weighted networks between the male patients with paranoid schizophrenia and male healthy controls, and to analysis the integrity of the white matter fiber tracts that connected to the different brain regions and its relationship with the course of disease. Methods Diffusion tensor imaging (DTI) data were obtained from 25 male patients with paranoid schizophrenia and 26 male healthy controls. The whole brain was parcellated into 90 regions by using the anatomical label map. Tractography was performed in the whole brain of each subject to reconstruct white matter tracts using the FACT algorithm. The brain white matter weighted networks were then constructed using the complex network theory. Results The strength of the nodes in the networks of schizophrenia significantly decreased in the right thalamus (P=0.03, corrected) and the right hes?chl gyrus (P=0.04, corrected). Negative correlation was found between the strength of the right thalamus and the course of disease (r=-0.45, P=0.03). Conclusion The integrity of the white matter fiber tracts connected to the thalamus and tem?poral lobes in the male paranoid schizophrenia is impaired. The lesion of fiber tracts connected to the thalamus is related with the course of disease.
