To observe the morphology of corneal endothelial cells after femtosecond laser in situ keratomileusis ( Femto-LASlK) .METHODS:From May to September in 2013, 88 eyes of 45 patients with myopia who accepted Femto-LASlK were enrolled in this study. The morphology of central corneal endothelial cells was measured by a non-contact corneal endothelial cell analyzer before, 1mo and 1a after surgery. The number, density, average size, size standard deviation, size coefficient of variation and hexagonality of the corneal endothelial cells were observed. All the measurements were analyzed by statistical analysis.RESULTS: All patients underwent operation smoothly, and no complication was observed during and after surgery;One month after surgery, the endothelial cell density (ECD) was 2815. 34±297. 07/mm2, which had a 2. 64% decrease compared with preparative ECD (t=4. 60, P= 0. 00), there was no statistical significance between ECD measurements of 1mo and 1a after surgery ( P>0. 05 ); One month after surgery, the size standard deviation ( SSD ) was 118. 47 ± 31. 58μm2 , which increased significantly compared with the preoperative SSD(t=-3. 87, P=0. 03), there was no statistical significance between SSD measurements of 1mo and 1a after surgery ( P>0. 05 );After surgery, the number, hexagonality, average size and size coefficient of variation of the corneal endothelial cells didn't change statistically(P>0. 05).CONCLUSlON: ln the early period after Femto-LASlK, the ECD decreased slightly, however this kind of surgery did not have significant harm to the function of corneal endothelial cells, and the surgery didn't cause the progressive loss of corneal endothelial cells.

Objective: To evaluate the clinical therapeutic effect and safety of decitabine in the treatment for adult acute myeloid leukemia (AML). Methods: Clinical information from 15 patients (> 18 years) with adult AML were collected between August 2009 and October 2010. The therapeutic effect and side reactions of decitabine were evaluated. Results: Of the 15 patients, 3 patients achieved complete remission (CR), five patients achieved partial remission (PR). The overall response rate was 53.3%. Of the 12 patients whose cytogenetic evaluation was accessible, one patient (8.3%) achieved complete cytogenetic remission. The median overall survival (OS) was 123 d (27-509 d), the median relapse-free survival (RFS) was 70 d (19-306 d), and the median duration of response was 33 d (11-176 d). The incidence rate of grade IV hematologic toxicity was 93.3%, and the incidence rate of grade III-IV infection was 33.3%. No severe bleeding, nausea and vomiting and liver injury (grade III-IV) were observed. Early death occurred in one patient. Conclusion: Decitabine can effectively treat adult AML with more severe hematologic toxicity, and it is necessary to give active supportive treatment. Copyright© 2011 by TUMOR.

Objective To explore the effect of nitric oxide (NO) on ?-aminobutyric acid B receptor (GABA_BR) subunits during recurrent febrile seizures (FS).Methods Twenty-four Sprague-Dawley rats aged 21 days were randomly divided into 4 groups: control group (37.0 ℃ water,n=8), FS group (45.2 ℃ water,n=8), FS + SNP group (45.2 ℃ water,n=8), FS+L-NMMA group (45.2 ℃ water,n=8). FS rats were induced 10 times in a warm-water bath, once every 2 days. The plasma level of NO was detected by the spectrophotometer. The expressions of GABA_BR subunit mRNA and c-fos gene were examined by in situ hybridization. The expressions of GABA_BR subunit and Fos protein were observed by immunohistochemistry. Results The plasma level of NO increased in FS + SNP group while decreased in FS+L-NMMA group compared with that in FS group. The expressions of GABA_BR_2 were down-regulated in FS+SNP group, while GABA_BR_1 hardly changed compared with those in FS group. In FS+L-NMMA group, both the expression of GABA_BR_2 and GABA_BR_1 up regulated compared with those in FS group. The expressions of c-fos gene and Fos protein were significantly enhanced after recurrent FS. SNP elevated the expressions of c-fos gene and Fos protein, while L-NMMA down regulated the expressions of them.Conclusion NO may play a regulatory role through modulating GABA_BR function in the pathogenesis of recurrent FS.

Psychrotrophs were isolated by using four media from low-temperature sewage of sewage treatment plant in Urumqi, Xinjiang. Totally, 154 strains were obtained including 12 filamentous fungi, 46 yeasts, 6 actinomycetes and 90 bacteria. The results of tolerance tests of the isolates to salt, phenol and SDS, and enzyme producing characters of amylase, proteinase and esterase were shown. Then 60 bacterial strains were chosen for 16S rRNA gene sequencing and analysis. The blasting results showed that the strains were assigned to 13 recognized genera , and the Strain 39 exhibited 96.6% similarity to Acinetobacter lwoffii(DSM2403), indicating that it might be a novel species. These results suggested that there were a lot of psychrotrophs and rich bacterial diversity in low-temperature sewage. In addition, which maybe an important and potential library of microbial resources.

Background Porcine fibrin sealant kit has been widely used in surgery for clotting and woundssealing.It is thought to be a substitution for inert gas and silicone oil in vitrectomy.But whether it produce toxic effect on retina or not after intravitreal injection is still studying.Objective This study aimed to investigate the retinal toxicity of porcine fibrin sealant kit following intraocular application.Methods Vitrectomy was performed on bilateral eyes of 15 pigmented rabbits.Porcine fibrin sealant kit of 0.5 ml was intravitreally injected in the lateral eyes of the rabbits as the experimental group,and equal volume of BSS was used at the same way in contralateral eye as control group.The inflammatory response of eye was observed under the slit lamp and ophthalmoscopy in 1 day,3,7,15,30 days after injection.Schi(o)tz tonometer was used to measure intraocular pressure(IOP) in 1 day,3,7 days,and retinal function was evaluated by electroretinogram (ERG) before operation and 30 days after operation.B-ultrasonic examination was carried out 30 days after surgery.Animals were sacrificed and eyeballs were obtained for retinal histopathological and ultrastructural examination in 30 days after operation.Results Complications appeared in 7 eyes of the experimental group,including cataract in 3 eyes,proliferation vitreoretinopathy and retinal detachment in 5 eyes,endophthalmitis in 1 eye,however,the cataract in 2 eyes and retina injury in 2 eyes were found in 15 control eyes.On the 30 days after injection,no inflammation was found in the 8 eyes without complication in the experimental group and 11 eyes in the control group.The IOP change was insignificant in different groups and various time points (Fgroup =0.008,P =0.929 ;Ftime =3.600 P =0.075).No significant difference was found in a-wave amplitude between groups and various time points(Fgroup =0.728,P =0.405 ; Ftime =0.516,P =0.482),and so was the b-wave amplitude (Fgroup =0.222,P =0.644 ; Ftime =0.057,P =0.814).On the 30th day after operation,arrangement of the retina was regular and no tissue edema and inflammatory cell infiltration were seen in both groups under the light microscope.Transmission electron microscope revealed that the ultrastructures of retinal cells,photoreceptor and retinal pigment cell were normal with the clear subcellular organelle,intact cellular membrane structure and mitochondria in both groups.Conclusions Domestic porcine fibrin sealant kit does not produce toxic effect on retina after intravitreal injection in rabbit.

Objective: To observe the clinical efficacy of acupuncture plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and analyze the effects on lower limb motor function, intelligence development level, immune function and cerebral hemodynamics.Methods: A total of 42 children with spastic cerebral palsy were selected as the observation objects, and enrolled into the observation group. Another 42 cases treated in the same period were selected as the control group. Both groups received MOTOmed intelligent motor training, and the observation group was given additional acupuncture therapy, and the control group was given additional conventional rehabilitation treatment. After 2 consecutive treatment courses, the psychomotor development index (PDI) and mental development index (MDI) of Children's Developmental Center of China (CDCC) scale, the scores of gross motor function measure (GMFM) scale and modified Ashworth scale (MAS), and the changes in CD3+, CD4+, CD8+ and CD4+/CD8+ were observed. The peak systolic velocity (PSV) and mean flow velocity (MFV) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) were observed and measured. The clinical efficacy was evaluated. Results: Compared with the same group before treatment, the scores of GMFM, PDI and MDI, levels of CD3+, CD4+ and CD4+/CD8+, PSV and MFV levels of ACA, MCA and PCA in both groups were significantly increased after treatment (all P<0.05), while the CD8+ level had no significant change (both P>0.05). After treatment, the total effective rate of lower limb spasm in the observation group was 90.5％, significantly higher than 71.4％ in the control group (P<0.05). The scores of GMFM, PDI and MDI, the levels of CD3+ and CD4+, PSV and MFV, and the levels of ACA, MCA and PCA in the observation group were all significantly higher than those in the control group (all P<0.05). There were no significant differences in the CD8+ level and CD4+/CD8+ between the groups (all P>0.05). Conclusion: Acupuncture plus MOTOmed intelligent motor training has a better clinical efficacy than conventional rehabilitation plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and is also superior in improving lower limb motor function and the level of intellectual development. And the mechanism may be related to the improvement of cerebral hemodynamics.
