The mature seeds and excised embryos of Dalbergia odorifera were used as materials to study the effect of moisture content on their survival, as well as the effect of rapid freezing and vitrification freezing method on seeds and in vitro embryos cryopreservation. The results showed that the germination rate and vigor decreased from 82.67%, 85% to 18.35%, 25% respectively, when the seed moisture content decreased from 15.04% to 8.14%; and the germination rate decreased from 82.67% to 37.50%, 25.37% respectively by vitrification freezing method and rapid freezing method, when the seed moisture content decreased from 15.04% to 9.37%. Among all the moisture content gradient, 12.35% moisture reached the maximal germination rate, which were 63.58% and 50.45% respectively by vitrification freezing and rapid freezing; and when the embryo moisture content was 26.32%, the germination rate decreased from 95.67% to 58.31% and 33.82% respectively by vitrification freezing and rapid freezing. And when the moisture content was in the range of 14.17% -21.34%, the germination rate was a bit of decrease. The experiment results showed that the optimum conditions of seed cryopreservation were: moisture content 12.35%, vitrification freezing; and the optimum conditions of in vitro embryo cryopreservation were: moisture 15.04%, vitrification freezing. In conclusion, the effects of moisture content on germination rate after cryopreservation in D. odorifera seeds and embryo were significant, and vitrification freezing method is much better than rapid freezing method.

Objective To observe the effects of hyperbaric oxygen combined with rehabilitation training on the motor ability of ischemic stroke patients.Methods Eighty ischemic stroke patients were randomly divided into a treatment group and a control group,with 40 cases in each group.The control group was treated with Bobath' s approach,while the treatment group was treated with Bobath's methods supplemented by hyperbaric oxygen therapy.The United States National Institutes of Health Stroke Scale (NIHSS),the Fugl-Meyer motor assessment scale (FMA) (lower part) and each patient's maximum walking speed (MWS) were used to evaluate the patients before,and after 8 weeks of treatment.Results After treatment the average NIHSS score,FMA score and MWS were 4.17 ± 1.4％,31.2 ± 3.3 and 54,.3 ± 16.2 m/min,respectively,in the treatment group.The control group' s results were 6.81 ± 1.2％,26.2 ± 2.2 and 45.6 ± 18.3 m/min.The intra-group differences in evaluation results before and after treatment were statistically significant in both groups.An inter-group comparison showed that the treatment group performed significantly better after treatment than the control group in terms of FMA and MWS.After treatment,the treatment group showed significantly better walking performance in terms of cadence,stride length,step length on the affected side,gait cycle and double support duration.Conclusion Hyperbaric oxygen can make rehabilitation training more effective in improving the neurologic deficits,motor function and walking ability of hemiplegic stroke survivors.

Objective To evaluate the effect of early continuous renal replacement therapy(CRRT)on patients with acute kidney injury(AKI)induced by severe sepsis. Methods A prospective study was conducted. 160 patients with AKI induced by severe sepsis admitted to intensive care unit(ICU)of Qingyuan People's Hospital between October 2009 and June 2013 were enrolled. According to the starting time of CRRT,the patients were randomly divided into two groups:an earl y treatment group and a regular treatment group(each,80 cases). All patients were treated in accordance with the principle of the cluster of severe sepsis. In early treatment group,the patents began to receive CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment over 6 hours,but the curative effect was not ideal. In the regular treatment group,the patients began to apply CRRT when the amount of urine output was<0.5 mL?kg-1?h-1 and had taken continuous conventional treatment persistently over 24 hours or difficultly corrected acidosis or heart failure developed. The changes in urine output,creatinine,saturation of blood oxygen,and albumin,and 28-day survival rate,length of ICU stay,time of organ support were measured and compared between the two groups to evaluate the therapeutic significance of the early CRRT. Results The mean length of ICU stay(day:6.5±1.7 vs. 8.2±1.6),length of organ support(day:5.3±1.8 vs. 6.0±1.4),the recovery time of urine amount(day:3.4±0.9 vs. 4.8±0.5)in early treatment group were significantly shorter than those in regular treatment group(all P<0.01);recovery ratio of urine in 1 week in early treatment group was significantly higher than that in regular treatment group(46.2%vs. 28.8%,P<0.05). The creatinine recovery ratio in 1 week in early treatment group was lower than that in regular treatment group(55.0%vs 78.8%),but there was no statistically significant difference(P>0.05). Early treatment group and regular treatment groups of creatinine recovery time were similar(day:5.1±1.3 vs. 5.2±1.2). 28-day survival rate in early treatment group was higher than that in regular treatment group(41.2%vs. 35.0%),but there was no statistically significant difference(P>0.05). Conclusion It is found that there is no evidence to suggest that early CRRT may improve the prognosis of the patients with AKI induced by severe sepsis,but it may be in favor of shortening the time of urine recovery,length of stay in ICU,length of organ support and length of dialysis.

AIM: To observe effect of the iris location to femtosecond - combined wavefront guided LASIK for myopia and astigmatism.?METHODS:The patients with astigmatism >1. 0D during the same time and followed up for 1a were selected. A total of 129 eyes in 67 patients were treated under iris location with femtosecond-combined wavefront guided LASIK ( experimental group) and 161 eyes in 82 cases with femtosecond-combined wavefront guided LASIK ( control group) . Laser cutting went with the same laser machine. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) , and wavefront aberration between the two groups were compared at 1, 3, 6mo and 1a after surgery.?RESULTS:At 1 and 3mo after surgery, the number of patients with better postoperative UCVA than preoperative BCVA between the two group showed a statistically significant difference (χ2=6. 423, P=0. 011,χ2=14. 431, P=0. 01 ); at 1d and 1mo after surgery, the residual astigmatism showed a statistically significant difference between two groups (t=1. 98, P<0. 05; t=2. 23, P<0. 05). At 3, 6mo and 1a after surgery, the differences on the change of residual astigmatism between the two groups weren’t significant ( P > 0. 05 ). At 6mo and 1a after surgery, the differences on UCVA between the two groups weren’t significant ( P > 0. 05 ). Until 1a after surgery, the root mean square ( RMS ) of high order wavefront aberration of the two groups, spherical aberration and coma aberration ( COMA ) were all enhanced compared to before surgery(P<0. 05). At 1, 3mo after surgery, the RMS showed a statistically significant difference between two groups (P<0. 05). At 1, 3, 6mo, 1a after surgery, the increase of COMA in experimental group was significantly lower than that in control group (P<0. 05).? CONCLUSION: Iris location technology applied in femtosecond - combined wavefront guided LASIK for myopia and astigmatism, can make the vision recovery faster, the RMS of high order and COMA increase less, the residual astigmatism less, show better and more stable treatment effect.

AIM:To contrast analysis of postoperative variation of corneal posterior surface heights after Femtosecond LASlK ( FS - LASlK ) and small incision lenticule extraction ( SMlLE) for high myopia.
●METHODS: Sixty-seven cases of high myopic patients (132 eyes) operated with laser corneal refractive in our hospital from May to Dec. in 2015 (-6. 00D≤spherical equivalent degree≤-10. 00D) were selected and divided into FS-LASlK group and SMlLE group. The thickness of corneal flaps at FS-LASlK and the thickness of map at SMlLE were designed to be 110μm. Corneal posterior surface heights were examined by Pentacam at preoperation, postoperative 3 and 6mo after FS-LASlK and SMlLE operation. Surface height changes after preoperative, postoperative 3 and 6mo were compared by measuring Pentacam corneal analysis system.
●RESULTS: Six months after operation, the FS-LASlK posterior corneal surface height was 6. 47 ± 1. 65mm, significantly higher than 5. 20 ± 1. 32mm before operation. SMlLE posterior corneal surface height was 6. 40 ± 1. 33mm, significantly higher than 5. 18 ± 1. 25mm before operation, the differences were statistically significant( P<0. 05). Six month after surgery, two methods of corneal surface height variation obtained was 1. 29 ± 1. 28mm and 1. 22 ± 0. 89mm, there was no significant difference ( P>0. 05).
●CONCLUSION:After FS-LASlK and SMlLE, the corneal posterior surface is protrusive. FS - LASlK is slightly obvious than SMlLE in early period. The stability of the posterior surface is better after SMlLE.
