Aim To investigate the effect of chronic intermittent hypobaric hypoxia ( CIHH) on the paeonol induced vasomotion of isolated rat ’ s thoracic aorta rings and its underlying mechanisms. Methods Spra-gue-Dawlay ( SD ) rats were randomly divided into 2 groups: control group ( CON ) and CIHH treatment group ( CIHH) . CIHH rats were exposed to hypoxia in a hypobaric chamber simulating 5 000 m altitude, 6 hours daily for 28 days. CON rats lived in the same en-vironment as CIHH animals except hypoxia. Organ bath technique was used to observe the effect of pae-onol on isolated thoracic aorta rings of rats. Results There were no significant differences of noradrenaline ( NE )- and KCl-induced contraction in thoracic aorta rings among CIHH and CON rats;CIHH enhanced va-sodilative effects of paeonol on isolated thoracic aorta rings of rats; the vasodilative effects on CIHH rats could be partly decreased by β-receptor blocker prop-ranolol,ATP-sensitive potassium channel ( KATP ) bloc-ker glibenclamide and NO synthase inhibitor L-NAME. Paeonol significantly inhibited NE-induced intracellular and extracellular calcium-dependent contraction in CIHH rats. Paeonol didn ’ t inhibit NE-induced con-traction by intracellular calcium release and its inhibi-tory effect couldn ’ t be blocked by glibenclamide in CON. Vasodilative effects of paeonol couldn ’ t be re-versed by indomethacin, a cyclooxygenase inhibitor, in CIHH and CON rats. Conclusion CIHH significantly enhances vasodilative effects of paeonol on isolated tho-racic aorta rings of rats. Besides promoting the signa-ling pathway of paeonol in CON, CIHH significantly enhances vasodilative effects of paeonol via activating KATP and inhibiting Ca2+ release from sarcoplasmic re-ticulum.

Objective To study the function of vascular endothelial growth factor (VEGF) in type 2 diabetes model rats and its effect on focal cerebral ischemia induced by middle cerebral artery occlusion in these rats. Methods Focal cerebral ischemia was induced by middle cerebral artery occlusion for 6 hours in type 2 diabetes rats and normal control rats.Blood vessels morphology was examined by ink perfusion,infarct size was measured by TTC and expression of VEGF and CD34 were evaluated by immunohistochemistry staining. Results Ink perfusion revealed increased number of small vessels in type 2 diabetes rats. Infarct size was significantly smaller in type 2 diabetes rats ( ( 80. 07 ± 11.21 ) mm3 ) than that in normal controls ((98. 91 ± 14. 86) mm3,t = 2.48,P = 0. 0326). There were more hemorrhage lesions in the ischemic hemisphere in type 2 diabetes rats when comparing with the controls. VEGF and CD34 showed significantly higher expression in type 2 diabetes rats than in normal controls. Conclusions High expression of VEGF and CD34 are found in type 2 diabetes rats after middle cerebral artery occlusion. There is cerebrolvascular remodeling in diabetes rats. While this diabetes-induced remodeling appears to prevent infarct expansion,the changes also increase the risk of hemorrhagic transformation. The latter may result in poor prognosis.

Objective To screen the differentially expressed genes in esophageal squamous cell cancer (ESCC) and normal tissue of esophageal mucosa in Kazakh. Methods RNA was extracted from the ESCC sections in Kazakh patients, and was amplified to obtain cRNA. The gene expression profiles in ESCC and normal tissue of esophageal mucosa were detected by HG-U133 Plus 2.0 gene chip. The results were analyzed by bioinfor-matics. Results One hundred and seventy differentially expressed genes in ESCC and normal tissue of esophageal mucosa were found, with a difference of more than 10 times in expression levels. Of the 170 genes, 39 were up-regulated (signal log ratio > 3 ) and 131 down-regulated (signal log ratio < - 3). These factors such as cell cycle regulation, apoptosis, cytoskeleton; extracellular matrix, intracellular signal transduction, protein translation and synthesis, and immunological functions were correlated with the genes with abnormal expression. Conclusion The use of oligonucleotide microarray accurately and efficiently screen the 170 target genes in ESCC in Kazakh. It is suggested that these genes may be related to the carcinogenesis and development of ESCC in Kazakh.

Objective:To investigate the clinical features of direct and indirect carotid cavernous fistulas (CCFs).Methods:Patients with CCF treated in the Affiliated Hospital of Xuzhou Medical University from January 2010 to August 2020 were enrolled retrospectively. Relevant clinical data were collected, including the main clinical manifestations, neuroimaging features, and treatment methods. The clinical features of direct and indirect CCFs were compared.Results:A total of 31 patients were enrolled in the study, 29 (93.5%) had ocular symptoms, of which conjunctival hyperemia and edema ( n=24, 77.4%), exophthalmos ( n=19, 61.3%) and orbital murmur ( n=18, 58.1%) were most common. There were 23 patients (74.2%) in direct CCF group and 8 (25.8%) in indirect CCF group. The former had more history of head trauma (78.2% vs. 12.5%; P=0.002), more flow volume (high-flow CCFs: 100% vs. 37.5%; P<0.001) and more likely to cause orbital murmur (69.6% vs. 25.0%; P=0.043). Endovascular embolization was safe and effective. The common methods of endovascular embolization were EVAL glue combined with coil embolization ( n=18, 66.7%) and detachable balloon embolization alone ( n=6, 22.2%). Conclusion:Ocular manifestations are most prominent in patients with CCFs. Direct CCF is more common, usually with a history of head trauma, and the clinical and imaging features are more typical. Interventional embolization is the preferred treatment option for patients with CCF.
