BACKGROUND:Several studies have confirmed that bone marrow mesenchymal stem celltransplantation exerts a certain neuroprotective role in cerebral infarction. Edaravone is a novel potent smal-molecule hydroxyl radical scavenger, which play a protective role in the brain by eliminating free radicals and inhibiting nerve celldamage after cerebral infarction. OBJECTIVE:To explore the influence of bone marrow mesenchymal stem cells combined with edaravone on expressions of aquaporin-4, Bcl-2, and brain-derived neurotrophic factor after cerebral infarction in rats. METHODS:Eighty Wistar rats were selected to establish models of cerebral infarction by right middle cerebral artery occlusion, and then randomly divided into control group, bone marrow mesenchymal stem cells group, edaravone group and edaravone+bone marrow mesenchymal stem cells group (combination group). After 6 hours of modeling, rats from these four groups were respectively injected via the tail vein with PBS, bone marrow mesenchymal stem cells, edaravone and edaravone+bone marrow mesenchymal stem cells. After 72 hours, the rats were decapitated to take brain tissues. Consequently, expressions of aquaporin-4, Bcl-2, and brain-derived neurotrophic factor mRNA and protein were determined by RT-PCR and western blot methods. After 12, 24 and 36 hours, TUNEL method was used for the determination of cellapoptosis. RESULTS AND CONCLUSION:The expressions of Bcl-2 and brain-derived neurotrophic factor were higher in the combination group than the other three groups (P<0.05), but the expression of aquaporin-4 was lowest in the combination group (P<0.05). The number of apoptotic cells in the combination group was significantly lower than that in the other three groups. These findings suggest that the combination of bone marrow mesenchymal stem cells and edaravone can improve expressions of Bcl-2 and brain-derived neurotrophic factor in the injured site, and significantly inhibit neuronal apoptosis. Meanwhile, the combination therapy can decrease expression of aquaporin-4 and mitigate cerebral edema, which is superior to bone marrow mesenchymal stem celltransplantation and edaravone alone.

Objective To understand the epidemic situation of common human soil-transmitted nematode infections in Quan-zhou City in 2012,so as to provide the evidence for improving the prevention and control measures. Methods The residents aged above 3 years from 5 townships in 2 counties were investigated to detect the parasite eggs(hookworm,Ascaris lumbricoides,Trich-uris trichura)by Kato-Katz technique. One kindergarten of each county was randomly selected and 228 children were investigated to detect Enterubius vermicularis eggs by the cellophane tape anus test. Results The total hookworm infection rate was 3.60%(69/1919). For the hookworm infection rates,there was no significant difference among different areas and between different genders, but there were significant differences among different age groups and different careers. No Enterubius vermicularis eggs were detect-ed. Conclusion The effect of the prevention and control of Ascaris lumbricoides,Trichuris trichura and Enterubius vermicularis in-fections is remarkable. However,the infection rate of hookworm has a rising trend and the prevention and control of hookworm in-fection should be strengthened.

BACKGROUND: The effect and mechanism of peroxisome proliferator-activated receptor gamma (PPARγ) agonists on transforming growth factor (TGF)-β1-induced fibrotic responses in lung fibroblasts remain unclear, and seldom reported.OBJECTIVE: To study the effects of PPARγ agonists on TGF-β1-induced fibrotic responses in lung fibroblasts, so as to investigate its effects in preventing pulmonary interstitial fibrosis of silicosis. METHODS: The pulmonary alveolar macrophage was prepared with 200 mg/L SiO2 and the supernatants were got. Chinese hamster lung fibroblasts were incubated with the prepared supernatants. Then a cellular model in vitro for studying pulmonary fibrosis induced by SiO2 was developed. Chinese hamster lung fibroblasts were cultured to observe the effects of the PPARγ ligand (15 d-PGJ2) and its agonists (troglitazone and ciglitazone) on the expression of TGF-β1-induced fibronectin. RT-PCR was used to detect the mRNA expression of fibronectin and Western blotting was used to detect the protein expression of fibronectin. RESULTS AND CONCLUSION: (1) The expression of TGF-β1 mRNA showed an effect in a dose- (0-5 μg/L) and time- (0-24 hours) dependent manner. (2) PPARγ ligands and agonists reduced the mRNA and protein expressions of fibronectin. Results suggested that PPARγ agonists can inhibit TGF-β1-induced fibronectin synthesis after stimulation by SiO2 and may play a potential role in preventing pulmonary interstitial fibrosis.
