ObjectiveTo explore the feasibility and efficacy of hyperbaric oxygen (HBO) therapy combined with mild hypothermi on severe craniocerebral injury (SCI).MethodsAll 80 SCI patients were randomly divided into therapeutic group (52 cases) and control group (28 cases). All patients received general synthesis treatment; while the hyperbaric oxygen combined with mild hypothermia treatment was added to the therapeutic group. Changes of Vm, Vs and PI of middle cerebral artery (MCA) in systolic stage were detected by transcranial-Doppler (TCD) before and after treatment. The plasma level of endothelin (ET) was also tested and prognosis of patients was analyzed.ResultsVm, Vs and PI of MCA in systolic stage improved obviously and ET reduced greatly in therapeutic group compared with those in the control group (P<0.01), and prognosis was also superior to control group.ConclusionHyperbaric oxygen combined with mild hypothermia can improve the consciousness state and prognosis of SCI patients as a result of the relaxation of the cerebral vascular spasm and the reduction of ET, which may contribute to the abatement of the cerebral ischemia and hypoxia.

Objective To investigate the effect of sevoflurane (Sero) preconditioning (Precon) on cardiomyocyte apoptosis following myocardial ischemia-reperfusion (I/R) in rats. Methods Sixty-four adult male SD rats weighing 270-350 g were randomly divided into 4 groups ( n = 16 each): group Ⅰ sham operation (group S); group Ⅱ myocardial I/R; group Ⅲ Sero and group Ⅳ Sevo-Precon + myocardial I/R. The animals were anesthetized with intraperitoneal pentobarbital 50 mg/kg, intubated and mechanically ventilated. PET CO2 was maintained at 35-45 mm Hg. Myocardial I/R was induced by 30 min occlusion of the left anterior descending branch of coronary artery followed by 2 h reperfusion in group Ⅱ and Ⅳ . In group Ⅲ the animals inhaled 2.5 % sevoflurane for 30 min while in group Ⅳ the animals inhaled 2.5% sevoflurane for 30 min at 15 min before myocardial I/R. Eight animals were killed at the end of 2 h reperfusion in each group. The hearts were removed for determination of myocardial infarct size (IS) as a percentage of area at risk (AAR) (IS/AAR) by triphenyl tetrazolium chloride staining. Myocardial apoptosis was detected using TUNEL and apoptosis index (AI) was calculated. Another 4 animals were killed before ischemia and at the end of 2 h reperfusion for determining the expression of Bcl-2 and caspase-3 protein in myocardium by Western blot. Results Sevoflurane preconditioning significantly decreased infarct size and AI in group Ⅳ as compared with group Ⅱ (group I/R). Bcl-2 protein expression was significantly decreased and caspase-3 protein expression was significantly increased after 2 h reperfusion as compared with the expression before ischemia in group I/R (group Ⅱ ). Sevoflurane preconditioning significantly reversed the I/R-induced changes in Bcl-2 and caspase-3 protein expression. Conclusion Sevoflurane preconditioning can attenuate myocardial I/R injury by decreasing myocardial apoptosis.

Ammonium perchlorate (AP), mainly used as solid propellants, was reported to interfere with homeostasis via competitive inhibition of iodide uptake. However, detailed mechanisms remain to be elucidated. In this study, AP was administered at 0, 130, 260 and 520 mg/kg every day to 24 male SD rats for 13 weeks. The concentrations of iodine in urine, serum thyroid hormones levels, total iodine, relative iodine and total protein, and malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) activity in thyroid tissues were measured, respectively. Our results showed that high-dose perchlorate induced a significant increase in urinary iodine and serum thyroid stimulating hormone (TSH), with a decrease of total iodine and relative iodine content. Meanwhile, free thyroxine (FT4) was decreased and CAT activity was remarkably increased. Particularly, the CAT activity was increased in a dose-dependent manner. These results suggested that CAT might be enhanced to promote the synthesis of iodine, resulting in elevated urinary iodine level. Furthermore, these findings suggested that iodine in the urine and CAT activity in the thyroid might be used as biomarkers for exposure to AP, associated with thyroid hormone indicators such as TSH, FT4.

Objective To explore link of change of plasma C-reactive protein (CRP) and atrial fibrillation (AF). Method The hsCRP enzyme-linked immunosorbent assay (ELISA) methods were used to measure plasma CRP levels in 21 patients with lone paroxysmal AF (LPAF) during AF and 7 days after return to sinus rhythm ;28 patients with lone sustained atrial fibrillation(LSAF) and 27 patients with rheumatic heart disease and chronic AF(RHD).Levels of plasma CRP were compared to levels in 32 patients with paroxysmal supraventricular tachycardia(PSVT) and 20 voluntary healthy subjects. Results Patients with LPAF,LPAF and RHD had high levels of CRP when compared with PSVT and the healthy subjects.No significant changes of CRP levels were found between the onset AF patients and those after 7 days of recovery.Patients with lone persistent AF and rheumatic heart disease with persistent AF had higher levels of CRP than those with LPAF,but have no significance.There were positive correlation between the duration of AF and the levels of CRP.But there were no relation with left atrial size on echocardiography,sex and ages. Conclusion These results indicate that elevated CRP levels in AF patients may play an important role in the occurrence and sustainment of AF.
