Objective To compare the effect between bilevel positive airway pressure (BiPAP) and routine drugs treatment to patients with obstructive sleep apnea hypopnea syndrome ( OSAHS ) complicated with stroke. Methods Twenty-nine patients with OSAHS complicated with stroke were randomly divided into two groups, 15 cases in the treatment group and 14 cases in the control group. Patients in the treatment group were applied BiPAP and routine drugs including degrading intracranial pressure, promoting blood flow, improving microcirculation. BiPAP were maintained for two months and over 10 hours daily. The control group was executed only routine drugs treatment. Results The difference of apnea hyponea index( AHI) and frequency of below 90% O2 saturation during sleep time between pre-therapy and post treatment was significantly higher in the treatment group(36. 8 ± 10. 7 and 105. 3 ± 17. 9) than in the control group (20. 8 ± 8. 1 and 44. 4 ± 24. 3 ) ( P < 0. 01 ) . The difference of lowest nighttime SaO2 between pre- and post-therapy was significantly higher in the treatment group( - 11. 7 ±8. 1)% than in control group(-2. 0 ± 8. 9) % ( P <0. 01). The difference of neurologic impairment score was significantly higher in the treatment group ( 16. 0 ± 2. 6) than in the control group ( 10. 1 ± 3. 6) ( P < 0. 01 ) . As for whole blood viscosity and red blood cell aggregation index,there was no significant difference between pre- and post-therapy(P> 0. 05). Conclusions BiPAP combined with routine drugs can significantly improve sleep anapnea indexs and neurologic impairment scores in patients with OSAHS complicated with stroke than only drug treatment. Blood rheology's indexs could not obtain amelioration in short period.

Objective To study the impact of viral infection on stress protein gene expression and investigate the possibility that heat shock proteins interact with viral components during viral assembly in the brain of suckling mice experimentally infected with Hantaan virus (HV). Methods New born mice less than 72 h of age were inoculated into brain with the 100 LD50 of Hantaan virus (strain 76 118). At the 8th day mice died from brain disease. Brains were prepared for tissue sections and extracts for the experiments. The Hantaan virus infection, HSP70 induction and their co localization in brain of infected suckling mice were demonstrated by immunohistochemical staining and laser scan co focal microscopic double labling. The possible intereaction between HV structural proteins and HSP70 was further analyzed by immunoprecipitation of infected tissue extracts with antibodies to either HSP70 or to viral nuclear capsule proteins HV NP by using SDS PAGE and Western blotting. Results HV infection induced an increased levels of HSP70 expression at the cytoplasma of neurons in the brain of suckling mice HV NP protein proved to be co localized with HSP70. Monoclonal antibody (mAb) to HSP70 could co immunoprecipitate the HV NP, and similarly mAb to HV NP could co immunoprecipitate HSP70 from virus infected tissue extracts, but not from mock infected tissue extracts. Antibody, which recognized one of these two proteins, did not cross react with the other. Thus, the association between HSP70 and HV NP appeared to be specific.Conclusions Hantavirus infection can directly induce HSP70 expression, leading to the formation of HV HSP 70 viral antigen peptide complex which plays some roles in the course of viral infection and replication.

Objective To investigate the effects of simvastatin preconditioning on the pulmonary heme oxygenase-1 (HO-1) expression in rats with lung injury induced by ischemia-reperfusion (I/R) of hind limbs. Methods Forty-eight adult male SD rats weighing 250-300 g were randomly divided into 6 groups ( n = 8 each) : sham operation group (group S) ; I/R group; I/R + simvastatin 1,5, 10 mg/kg groups (S1 , S2, S3 groups) ; simvastatin control group (group SC) . I/R of hind limbs was produced by occlusion of bilateral femoral arteries for 2 h followed by 3 h reperfusion. Croups S1 , S2 , S3 received simvastatin 1, 5, 10 mg/kg respectively via an oro-gastric tube for 3 days before I/R. Group SC received simvastatin 10 mg/kg via an oro-gastric tube for 3 days. Arterial blood samples were taken at 3 h of reperfusion for blood gas analysis and PaO2 and PaCO2 were recorded. The animals were then sacrificed and the lungs removed immediately for pathologic examination and determination of the wet/dry lung weight ratio (W/D ratio), superoxide dismutase (SOD) activity and polymorphonuclear neutrophil (PMN) count . Hie expression of HO-1 mRNA and protein in lung tissues was detected using RT-PCR and Western blot analysis respectively.Results Alveolar edema, localized pulmonary atelectasis and large amount of PMN infiltration were found in I/R group and were ameliorated in S1, S2, S3 groups. Compared with group S, PaO2 and PaCO2 were significantly decreased in I/R group, W/D ratio and PMN count were increased and SOD activity was significantly decreased in I/R, S1 , S2 groups, and expression of HO-1 mRNA and protein was up-regulated in the other five groups ( P < 0.05). PaO2, PaCO2 and SOD activity were significantly increased, W/D ratio and PMN count were significantly decreased, and HO-1 mRNA and protein expression was up-regulated in S1, S2 and S3 groups as compared with I/R group ( P < 0.05 or 0.01). W/D ratio and PMN count were gradually decreased, SOD activity was gradually increased, and HO-1 mRNA and protein expression was gradually up-regulated in S1, S2 and S3 groups. Conclusion Simvastatin preconditioning has protective effect against lung injury induced by I/R of hind limbs in rats through up-regulation of HO-1 expression in the lung tissues and in a dose-dependent manner.

Three bacteria of decomposing lecithin and 4 bacteria of dissolving aptite were incubated for 4 weeks with sand media respectively. Phosphorus in the sand was extracted with distilled water and measured by different methods. It was found that the bacteria have a quite different ability to release P from the materials. Part of the P released became organic phosphorus compounds in microbial tissue. However, a large amount of the P was reserved in microbial cells in a form of phosphates. The direct measurement of P in the extract by molybdenum blue method would underestimate the capacity of the bacteria to release P from the materials. The correct approach was that the sand was fumigated with chloroform and then digested with acid before the measurement by molybdenum blue method.

Objective To evaluate the relationship between ambulatory arterial stiffness index (AASI) and intracranial and extracranial arterial stenosis in 146 patients with ischemic cerebrovascular disease. Methods Degree of intracranial and extracranial arterial stenosis in 146 patients with ischemic cerebrovascular disease was assessed by CT angiography (CTA). Then all patients were divided into 4 groups according to the numbers of branches with stenosis: no stenosis group, 1 branch group, 2 branches group, and 3 and more than 3 branches group. Dynamic blood pressure was monitored to calculate the AASI. Results There was no significant difference of AASI among the extracranial arterial stenosis groups (P=0.614). AASI was positively correlated with the degree of intracranial artery stenosis (r=0.743, P<0.05), and with 3 and more intracranial artery branches stenosis (r=0.797, P<0.05). Conclusion AASI is closely correlated with the degree and numbers of branches of intracranial artery stenosis.
