Objective To evaluate the long-tem effect of adaptive servo ventilation (ASV) on patients with chronic heart failure (CHF) and sleep-disordered breathing (SDB). Methods The controlled clinical articles were searched included in PubMed, Cochrane, EMBASE and CBM, CJFD, WangFang Database from Jan. 1970 to Dec. 2015. Included standard: left ventricular ejection fraction (LVEF) ≤55%, apnea hypopnea index (AHI) ≥15/h, follow up period over 4 weeks. After quality assessment (modified Jadad score) and data extraction by two independent reviewers, mete analysis was performed with RevMan 5.3 software. Results Thirteen studies were recruited including 442 cases being followed over 4 weeks [ASV group 233 cases and control group 216 cases (corssover design 7)]. Compared to control group, LVEF increased [weighted mean difference (WMD)=3.72, 95%CI: 1.80-5.64, PP<0.01] and AHI decreased significantly (WMD=–18.63, 95%CI: –26.19-–11.08), the distance walked in 6 minutes increased (WMD=28.72, 95%CI: 2.26-55.18, P=0.03) and plasma N terminal brain natriuretic peptide precursor (NT-pro BNP) decreased significantly (WMD=–744.03, 95%CI: –1262.45-–225.62, P<0.05) in ASV group. Conclusion Over 4 weeks ASV may improve LVEF and AHI, increase 6-min walking distance and decrease NT-pro BNP in patients with CHF and SDB.

In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.

Seeds of Bupleurum chinense cultivar, Zhongchai No. 1, were sowed in plastic pots which used the arable layer soil as the nursery bed and putted in the artificial climate incubator at various temperatures (15, 20, 25, 15-25 degrees C) and light (8,12 h) to germinate, respectively. The lower constant temperature (15 degrees ) and the higher constant temperature (25 "C) were not conducive to the sprouting characteristics of B. chinese. While they were able to enhance root activity to some extent; The seeding growth of B. chinese was significantly better in the variable temperature than correspondence in the constant temperature, significantly. The emergence speed, emergence index, vigor index and root activity of Bupleurum were improved under the 12 h of light-time, but the germination rate was not improved. The sprouting of Bupleurum's seeds could be improved to some extent by soaking with hormone, such as gibberellin, cytokinin, salicylic acid. Gibberellin promoted seeds' sprouting and seedings's root activity of Bupleurum, while salicylic acid increased the root activity of seeding. There is a significant influence of light, temperatures and hormone treatment on the germination of Zhongchai No. 1 seeds, and all three are remarkably interacted; It is beneficial to promote seed germination by the temperature (20 + 5) degrees C, lighting (8 h) and gibberellin concentration (10 x 10(-6)).

Objective To establish a rabbit model of facial skin lifting and to evaluate the skin lifting effects of absorbable soft tissue plastic belt, and to provide experimental basis for clinical application of this plastic belt.Methods 36 Japanese white rabbits were randomly divided into model control group (n=6) and plastic belt lifting group (n=30). The model control group received only facial skin resection surgery, while the plastic belt lifting group had facial skin resection and plastic belt implantation.The changes of rabbit general status, skin lifting effects, performance of plastic belt and pathological changes of subcutaneous tissue after implantation were determined during the 4 weeks after surgery. Results The rabbit skin wound was healed within 3-7 days after surgery without infection.Meanwhile, the plastic belts did not show shifting or rupture, and only whitening around the perforations was observed in the two groups.Compared with the model control group, the MA and MB distances in the plastic belt lifting group were significantly lower ( P<0.01 ) , while the biological tension of plastic belts in the facial skin lifting rabbit models was significantly increased with the extension of time after implantation (P<0.01), and the biological tension was 18.62 N at 4 weeks after transplantation. In addition, the tensile intensities of perforations and plate in the two groups were significantly reduced at 4 weeks postoperatively (P<0.01), the tensile intensity of perforations and plate in the two groups were maintained at 35.07 N and 53.31 N, respectively, and the perforations/plate tensile intensity ratio of the two groups remained unchanged during 4 weeks after transplantation ( P >0.05 ) .Moreover, the molecular weight ( Mw ) , peak molecular weight ( Mp ) , Z molecular weight (Mz) and viscosity were gradually decreased along with the time passing after implantation (P<0.01), and its dispersion Mz/Mw ratio was also gradually decreased from 2 weeks after implantation (P<0.01), and no obvious pathological changes were found after subcutaneous implantation of the plastic belts.Conclusions We have successfully established a facial skin lifting rabbit model, and the plastic belt can obviously lift the facial skin fascia system and keep intact more than 4 weeks in the body.Therefore, this plastic belt can be applied for anti-wrinkle facial soft tissue lifting against the skin damage caused by aging.

MAIN OUTCOME MEASURES: Free running EMG and stimulus triggered EMG, including time, frequency, amplitude, muscle group were observed and recorded simultaneously. Never root functional injury and restoration after surgery were detected.RESULTS: 378 pedicle screws in 74 patients were monitored intraoperatively, and only 3 pedicle screw malposition (2 of L_4, 1 of L_5) was detected and then replaced with the help of C-arm fluoroscopic examination. Myoelectricity appeared when the current intensity was less than 10 mA. The correct rate of implantation was 99.2%. Nerve root impingement was found in two cases during laminectomy for L_5 and S_1 decompression and never root solution, which alerted the surgical team of critical neural structures. Nerve symptoms of the lower limb were aggravated after surgery and restored following 2-4 weeks of conventional treatment. The error injury rate of nerve root was 2.7%. In all reported cases, no irreversible neurological deficit was observed 2-4 weeks after operation.CONCLUSION: Intraoperative EMG monitoring can find improperly placed screws and detect impending nerve root injury promptly. Combined EMG and 3-D imaging modality monitoring is a reliable and practicable method that can be used to protect neural structures during complex lumbosacral surgery.
