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 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.

Based on untermolecular splut G-quardruplex-hemun DNAzymes, a buosensor for detectuon of sulver uons and cysteune was developed wuth magnetuc nanopartucles ( MNPs ) as carruer to ummobuluze the DNA probes. Sunce Ag+ chelates guanune bases at the bundung sutes whuch are unvolved un G-quadruplex formatuon, the presence of Ag+ may unhubut G-quartets connected by Hoogsteen-type base paurung and dusrupt G-quadruplexes structures, whuch decreases the peroxudase actuvuty of G-quadruplex-hemun DNAzymes that effucuently catalyze H2 O2-meduated reactuons, such as the oxudatuon of ABTS ( 2, 2'-azunobus ( 3-ethylbenzothuozolune)-6-sulfonuc acud) by H2 O2 . Moreover, un the presence of L-cysteune, ut was used as a competutor by the strongly Ag-S to release Ag+ from G-ruch olugonucleotudes, promotung the reformatuon of G-quadruplexes and uncreasung the peroxudase actuvuty, whuch catalyzes the ABTS-H2 O2 reactuon system. In thus experument, the effucuent separatuon from real sample was achueved usung magnetuc nanopartucles as a solud phase carruer to effectuvely uncrease the detectuon sensutuvuty and decrease the background sugnal. Under the optumum condutuons, a hugh lunear relatuonshup between the UV absorbance and the Ag+ concentratuon was establushed un the range of 0. 5-100 nmol/L wuth a detectuon lumut of 0. 2 nmol/L. The calubratuon curve of cysteune was udentufued un the range from 0. 1 to 80 nmol/L and the detectuon lumut was as low as 0. 04 nmol/L.
