Objective To investigate the frequency of lesions detection in patients with cerebral infarction (CI) with SPECT/CT. To investigate fluctuation of regional cerebral blood flow (rCBF) and its relationship with clinical symptoms. Methods Sixty-seven CI patients without cerebellar lesion were randomly selected. The rCBF in the regions of interest (ROI) was examined by SPECT/CT, which was collected from the frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, basal ganglia and cerebellum. The rCBF index was calculated. The association between fluctuation of rCBF index and clinical symptoms of patients was explored. Results There were 251 positive regions in all viewing regions , the total positive rate was 31.2%. The left side was 38.1%, while the right side was 24.4% (χ2=17.522,P < 0.01). In normal group, there were no statistical difference of average rCBF between two halves (P > 0.05). However, the average rCBF on the left parietal lobe was lower (P < 0.01). The average rCBF in the abnormal group was lower than that in ipsilateral normal group (P < 0.01). The average rCBF index in the abnormal group was higher (P < 0.01). In normal group , the average rCBF on the frontal lobe and parietal lobe was low , but the average rCBF on the thalamus and basal ganglia was high (P < 0.01). In abnormal group, there were no statistical difference in the average rCBF (P >0.05). rCBF≥0.7 is a clinical sign of abnormal ROI. Conclusion 30% of ROI of CI patients have lesions and the positive rate of the left side was higher. The biological rCBF values of all lobes were different. Therefore, rCBF index could be used to reflect whether the ROI is normal. rCBF≥0.7 could be used as a sign to quantitatively assess abnormal ROI in clinical practice.

AIM:To investigate the effects of nodosin extracted from Chinese traditional medicine on the pro-liferation of HepG2 cells cultured in vitro and to detect the protein expression of Bcl-2 and Bax in HepG2 cells.METH-ODS:HepG2 cells were treated with different concentrations (1.25, 2.5, 5, 10 and 20 μmol/L) of nodosin for 24 h. The morphological changes of HepG2 cells were observed under inverted microscope.The inhibitory rates of HepG2 cell growth were detected by MTT assay.The apoptotic rates and the protein expression of Bcl-2 and Bax were analyzed by flow cytometry.RESULTS:Shrunken and suspended HepG2 cells increased with the increases in the concentrations of nodo-sin.The apoptotic rates and the expression of Bax increased with the increases in the doses of nodosin, while the expression of Bcl-2 decreased.CONCLUSION:Nodosin inhibits the growth of HepG2 cells in a dose-dependent manner.The inhibi-tion of HepG2 cell growth is induced by decreasing Bcl-2 and increasing Bax, thus promoting cell apoptosis.
