Objective To investigate the protective effect of methylene blue (MB) on blood-brain barrier (BBB) injury after focal cere-bral ischemia-reperfusion in rats. Methods 18 male Sprague-Dawley rats were randomly divided into sham-operated group (n=6), model group (n=6) and MB treatment group (n=6). The left middle cerebral arteries were occluded for 1 hour and reperfused. MB was infused intra-venously immediately after reperfusion (3 mg/kg) and again 2 hours post-reperfusion (1.5 mg/kg), while normal saline was administered in the model group. The sham-operated group was treated as same as the model group without occlusion and infusion. HE staining was used to observe the histological injury in the cortex around the infarcted region 47 hours after reperfusion, while albumin immunohistochemistry was used to evaluate the permeability of the BBB, and immunohistochemistry and double immunofluorescence staining were used to exam-ine the expressions of glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP-4). Results HE staining showed that cells and blood ves-sels were not intact in the cortex around the infarcted region in the model group and they were better in the MB treatment group. The expres-sions of the albumin, GFAP and AQP-4 were higher in the model group than in the sham-operated group (P<0.01), and were lower in MB treatment group than in the model group (P<0.05). The double immunofluorescence staining showed the colocalization of GFAP and AQP-4 in the astrocytes. Conclusion MB may ameliorate the BBB disruption induced by focal cerebral ischemia-reperfusion through reducing glio-cyte proliferation and down-regulation of AQP-4 expression in rats.

Objective To explore the expression of aquaporin 4 (AQP4) in primary and secondary cultured rat astrocytes. Methods Rat cortical astrocytes from a newborn (one day) Wistar rat were cultured. Astrocytes were identified with immunofluorescence staining of glial fibrilillary acidic protein (GFAP). The expression of AQP4 was determined with real-time quantitative polymerase chain reaction and immu-nofluorescence staining three, five, seven and nine days of primary culture, and nine days of secondary culture. Results The purity of GFAP-positive cells was more than 95%. The expression of AQP4 mRNA was found three days of primary culture, remained unchanged five days of primary culture (P>0.05), and increased seven and nine days of primary culture (P<0.05). The expression of AQP4 mRNA was not different between nine days of primary culture and nine days of secondary culture (P>0.05). AQP4 immunofluorescence staining showed the same trend of AQP4 mRNA. Conclusion AQP4 may express since three days of primary culture in rat astrocytes in vitro, and increase slowly until nine days of primary culture.

OBJECTIVE:
To observe and analyze the function and morphology of pharyngeal ostium of the eustachian tubes in secretory otitis media and chronic rhinosinusitis in children under direct vision,in order to provide an objective basis for clinical treatments.
METHOD:
Fifty cases of secretory otitis media,50 cases of chronic rhinosinusitis and a control group of 50 cases with hoarseness were examined under video laryngoscope to observe the pharyngeal ostium morphological changes of the eustachian tubes, and their functional statuses were tested by using acoustic impedance instrument. All the data were analyzed by statistical methods.
RESULT:
(1) In the secretory otitis group, the abnomal rate of the pharyngeal ostium of the eustachian tubes was 94% while the chronic rhinosinusitis group was 80%,and between them there was no significant differences (P > 0.05). But both of them had significant differences with the control group (P < 0.05). (2) In the secretory otitis group, the rate of the eustachian tube dysfunction was 70% while the chronic rhinosinusitis group was 26%, and between them there was significant differences (P < 0.05), and both of them have significant differences when compared with the control group (P < 0.05).
CONCLUSION
There are some abnormal points exist in the function and the morphology of the eustachian tube in secretory otitis media and chronic rhinosinusitis in children. Eustachian tube dysfunction played a dominant role in the pathogenesis of secretory otitis media in children rather than the morphological change did compared to the chronic rhinosinusitis in children.

Objective To investigate the expression changes of astrocytic syntrophin in hippocampus from human mesial temporal lobe epilepsy (MTLE). Methods From April, 2015 to July, 2016, 17 cases of hippocampus, collected from temporal lobectomy, were divided into MTLE group (n=13) and non-MTLE group (n=4) according to hematoxylin and eosin staining, glial fibrillary acidic protein and neuronal nu-clei immunohistochemical staining. Immunofluorescence double labeling and immunofluorescence histochemistry were used to observe the expression of syntrophin. Results The proliferation of astrocytes increased and neurons reduced in the hippocampus of MTLE group. Syntro-phin was found in the membrane and foot processes of astrocyte, that was enriched along perivascular astrocyte end-feet domain in non-MTLE group, but lost in MTLE group. While the whole expression of syntrophin was more in MTLE group than in non-MTLE group (t=5.421, P<0.001). Conclusion The distribution of syntrophin in hippocampus astrocytes may be related to the development of MTLE.
