BACKGROUND:Our previous study has already manifested that Chinese medicine Xiaokening can effectively prevent and treat the early diabetic nephropathy. OBJECTIVE:To compare the effect of rhein and archen on the apoptosis of mesangial cells of rats cultured with high glucose. METHODS:Mesangial cells were stimulated by different concentrations of rhein and archen (20, 40 and 80 μmol/L). Morphology of apoptotic cells was observed by hematoxylin-eosin staining. Karyon apoptosis was examined by fluorescence staining of DAPI. cellapoptosis rate was detected by flow cytometry. RESULTS AND CONCLUSION:The outcome of hematoxylin-eosin staining and DAPI staining indicated that the effect of rhein was much stronger than that of archen on the apoptosis of mesangial cells in the rats cultured with high glucose. Comparison of the apoptosis rate also indicated that the rhein had a stronger effect on the earlier and the later stage apoptotic rate of mesangial cells than archen. Both rhein and archen with different concentrations can induce apoptosis of mesangial cells, but the effect of rhein is much stronger.

OBJECTIVETo explore the effect of drug-containing serum of Chinese herbal compounds [Xiongshao Capsule (XS, for activating blood) and Huanglian Capsule (HL, for dispelling toxin)] on tumor necrosis factor-alpha (TNF-alpha)-induced adherence between human umbilical vein endothelial cells (HUVECs) and polymorphonuclear neutrophils (PMN), inflammatory reaction and expression of related proteins in mitogen-activated protein kinase (MAPK) pathway.
METHODSThirty-two rats were randomly divided into four groups (8 in each group) using random digit table: the blank control group treated with distilled water, the test group I treated with Chinese herbal compound of XS (0.135 g/kg), the test group II treated with Chinese herbal compound of HL (0.135 g/kg), and the test group Ill treated with Chinese herbal compound of XS (0.135 g/kg) and HL (0.135 g/kg). All medication was given by gastrogavage once a day for a week. Rats' blood serum was harvested 1 h after the last administration to prepare drug-containing serum. HUVECs were exposed to TNF-alpha (100 ng/mL) to induce cell injury model and incubated with corresponding drug-containing serum (10%) for 24 h. Normal rats' serum was given to cells in the blank control group and the model group, while XC + HL containing serum was given to cells in the rest 3 groups. The adherence of HUVECs and PMN cells was detected by using rose bengal strain. Levels of E-selectin, intercellular adhesion molecule-1 (ICAM-1), and interleukin-1beta (IL-1P) in the supernatant of cultured HU-VECs were determined by ELISA. Protein expressions of mitogen-activated protein kinases p38 (p38MAPK) and extracellular signal-regulated kinase 1/2 (ERK 12) were determined by Western blot.
RESULTSCompared with the blank control group, HUVECs were seriously injured; PMN adherence amount significantly increased; levels of E-selectin, ICAM-1, and IL-1beta increased; expression levels of p-p38MAPK and p-ERK 1/2 in the supernatant of HUVECs significantly increased in the model group (all P < 0.01). Compared with the model group, HUVECs-PMN adherence amount decreased (P < 0.05); levels of E-selectin, ICAM-1, and IL-1 beta in the supernatant of HUVECs decreased (P < 0.01, P < 0.05); expression levels of p-p38MAPK and p-ERK 1/2 of endothelial cells decreased in the test group I, II, and III (P < 0.01).
CONCLUSIONSDrug-containing serums of activating blood, activating blood and dispelling toxin could attenuate TNF-alpha induced injury of HUVECs, inhibit HUVECs-PMN adherence and the release of adhesion factors. Its mechanism might be involved with protein phosphorylation of p38MAPK and ERK 1/2 in the MAPK pathway.

AIM: To investigate the expression of osteopontin (OPN) and CD44 in human renal proximal tubular epithelial cells stimulated by human serum albumin (HSA). METHODS: Proximal tubular epithelial HK-2 cells were stimulated by HSA at different concentrations for different time, then OPN mRNA production was detected by RT-PCR, and OPN protein was detected by Western blotting. The expression of OPN and CD44 in HK-2 cells after stimulation for 24 h or 48 h were detected by immunofluorescence with confocal laser scanning microscope. RESULTS: Osteopontin mRNA in HK-2 cells showed a highest expression at 3 h and 48 h after HSA stimulation. However, the expression of OPN protein in HK-2 cells reached the maximum at 24 h after HSA stimulation. OPN mRNA and protein showed a strong dose-dependence relation with the concentration of HSA. HSA also stimulated HK-2 cells to express CD44 protein, the fluorescence of CD44 was most prominent at 48 h after HSA stimulation. CONCLUSION: HSA stimulates human renal proximal tubular epithelial cells to express OPN and CD44.

Aim To investigate the effect of polysac-charide of Cistanche deserticola ( CDPS) on the impro-ving ability of synaptic plasticity in memory acquisition impairment model mice induced by scopolamine. Methods The KM mice were randomly divided into six groups:scopolamine group, control group, CDPS-treated (25, 50, 100 mg·kg-1 ) group and donepezil group. Memory acquisition impairment model in mice was established with i. p. scopolamine (4 mg·kg-1 ) only once, and orally administered CDPS (25, 50, or 100 mg · kg-1 ) daily for 6 weeks before scopolamine injection. Experimental groups were subjected to step-down test and Morris water maze test. Western blot and RT-PCR analysis were used to examine the expression of GAP-43 , SYP and PSD-95 . Transmission electron
microscope was used to observe the change of synaptic number and structures. Results CDPS (25,50,100 mg·kg-1 ) could shorten the incubation period of mice in the water maze test. Control group and CDPS-treated group swam longer in Q3 than scopolamine group. Mo-reover, CDPS (50,100 mg·kg-1 ) could significantly reduce the error times and extend the incubation period in the step-down test. The results of Western blot and RT-PCR showed that CDPS significantly improved the expression of GAP-43 at the dose of 25 ,50 mg · kg-1 and SYP at the dose of 25,50, 100 mg·kg-1 in hip-pocampus of mice. However, the biochemical assays did not reveal a significant difference in the basal hipp-ocampal levels of the PSD-95 . The ultra-thin speci-mens of hippocampus showed that the number of syn-
apse was increased in CDPS-treated group. Conclu-sions Scopolamine can induce the learning and mem-ory deficits in mice to make related protein expression abnormalities in hippocampus mice, thus this causes the change of synaptic plasticity, which leads to a change in the ability of learning and memory. And CDPS can improve the expression of SYP and GAP-43 ,
increase number of synapses, recover synaptic plastici-ty, and improve the ability of learning and memory in mice.
