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 explore the feasibility of the nested PCR technique to detect the Trichosporon asahii DNA in the blood and liver samples from the murine model of disseminated trichosporonosis.Methods On day 3,7,14 after intravenous inoculation of Trichosporon asahii suspension,blood and liver samples of 30 BALB/c mice were collected.Another ten normal mice serve as control.DNA was amplified by nested PCR,with a pair of primer.Fungal culture was done as control.Results On day 3,7,14 after inoculation,the positive rate of the serum fungal cultivation were 0,20%,0;the positive rate of the serum after nested PCR assay was 80%,90%, 88.9%;the positive rate of liver fungal cultivation were 50%,40%,22.2%;the positive rate of liver after nested PCR assay was 90%,90%,88.9%.There were statistical differences between the positive rate by nested PCR assay and fungal cultivation to check the serum and liver samples on day 3,7,14 after inoculation.The survival mice to the 14~(th) day were too less to make statistical analysis.Conclusion The results suggest that T.asahii DNA assay by nested PCR is more specific,more sensitive,and faster than fungal cultivation.The nested PCR assay could be a potential assay for the diagnosis of disseminated trichosporonosis.

BACKGROUND: Previous studies demonstrated that recombinant human bone morphogenetic pretein-7 (hBMP-7) can effectively promote the synthesis of extracellular matrix, repair of damaged disc matrix, restore of degenerative disc height. It is hoped that BMP-7 can be used to control and reverse the intervertebral disc degeneration. However, because of the short half-life of recombinant protein and low biological activity, it is difficult to maintain BMP-7 high concentrations on degenerative disc. Gene therapy can prevent these defects effectively.OBJECTIVE: To study the effect of hBMP-7 gene transfeotion on biological activity of primary cultured rabbit nucleus pulposus cells in vitro, to determine the feasibility of hBMP-7 gene which will on gene therapy research of intervertebral disc degeneration,and to provide basis for further study.DESIGN, TIME AND SETTING: A randomized and controlled observation was performed at the Institute of Cardiothoracic Surgery of Changhai Hospital from December 2005 to September 2006.MATERIALS: Six healthy New Zealand white rabbits of either gender, averaging 4 weeks old and weighing 500 g, were used in this study, and Ad-hBMP7 was constructed by the Cardiothoracic Surgery Institute of Changhai Hospital.METHODS: After rabbits sacrifice under aseptic condition, the nucleus pulposus was got. After digested with Pronase, type Ⅱcollagenase and type Ⅱ DNAase (4 hours, 37 "(2), the cells were seeded in the Petri dishes and were kept in the incubator. After 7 days and then twice a week, the media were refreshed. The nucleus pulposus cells were infected by adenovirus integrated with hBMP7 gene. The cells which were transfected by adenovirus vector for Lac-Z gene and which were not transfected were adopted as control.MAIN OUTCOME MEASURES: The expression of hBMP-7 was determined by RTopCR and Western blot. The effect of hBMP-7 on cell proliferation was surveyed by MTT. Furthermore, the effect of hBMP-7 gene on synthesis of proteoglycan and type Ⅱcollagen was detected by modified dimethylmethylene blue method and ELISA, respectively.RESULTS: Gene sequencing and PCR showed that hBMP-7 gene was inserted correctly and no mutation happened. The pdmary cultured rabbit nucleus pulposus cells were identical with those reported in literature. After Ad-hBMP7 transduct into the nucleus pulposus cells, high level of hBMP-7 expression was observed and lasted over 3 weeks. Also hBMP-7 gene can promote cell proliferation and synthesis of proteoglycan and type II collagen with significant difference compared with control groups (P < 0.05).CONCLUSION: hBMP-7 gene mediated by adenovirus can be the target gene for the further study on gene therapy of intervertebral disc degeneration.

Objective To investigate the molecular mechanism of Loureirin A mediated anti-hepatic fibrosis by evaluting its effects on proliferation , secretion ofα-smooth muscle actin (α-SMA) and transforming growth factor-beta1 (TGF-β1), and expression of rat hepatic stellate cells in vitro . Methods Primary hepatic stellate cells were isolated and cultured from Sprague-Dawley rats. After activating and inducing primary hepatic stellate cells from qHSC to aHSC, the activated hepatic stellate cells model in vitro was established. Then we observed the morphological changes of static hepatic stellate cells and activated hepatic stellate cells with inverted phase contrast microscope. Cultured hepatic stellate cells were treated with different concentrations of loureirin A and the inhibitory rate of HSCs proliferation was measured by MTT assay. The expression of Frizzled-4 was measured by western blot analysis. The content ofα-SMA and TGF-β1 in the cultured HSCs'supernatant were measured by enzyme-linked immunosorbent assay (ELISA) . Results Loureirin A the proliferation of inhibited activated hepatic stellate cells in a time-dose-dependent manner compared with the control group,IC50=0.30 μg/μL. After loureirinA treatment of the HSCs, western blot analysis showed that Frizzled-4 expression level was obviously lower than control group. Loureirin A also inhibitedα-SMA and TGFβ1 (P<0.05) secretion in the cultured HSCs'supernatant in different degree by the assay of ELISA. Conclusions The molecular mechanism of Loureirin A and Wnt signaling pathway mediated anti-hepatic fibrosis and anti-angiogenesis may involve down-regulation the expression of Frizzled-4, inhibiting the synthesis and secretion ofα-SMA,TGF-β1and the proliferation of HSCs.
