Objective To investigate the angiogenesis effect induced by hone marrow mobilization on the ischemic hindlimbs of diabetic mice.Methods Diabetes mellitus was induced in mice by injection of streptozotocin.To observe the angiogenesis effect in ischemic limbs,unilateral femoral artery and all the side branches were excised and then was given granulocyte-colony stimulating factor (G-CSF) for bone marrow mobilization.Results The level of nitric oxide (NO) in plasma was significantly lowered 8 weeks after establishment of diabetes mellitus.After mobilization for 8 days,CD_(34)~+ cells in peripheral blood of mice were increased significantly [from (0.15?0.05)% to (2.30?0.41 )%],the vascular endothelial growth factor (VEGF) mRNA level of ischemic limb,which was examined with semi-quantitative RT-PCR,became higher in diabetic mice than that in non-diabetic mice.Two weeks following mobilization,the blood perfusion detected by LASER Doppler perfusion scan in the ischemic hindlimbs was significantly higher in the diabetic mice than in that the nondiabetic mice [(76.37?6.10) % vs (18.07?3.40) %,P＜0.05],vWF immunohistochemical staining showed that the density of capillaries was significantly greater in the mobilization group than that in the non- mobilization group [ (26.6?4.8 vs 11.5?2.6 )/per field,P＜0.05 ].Conclusion Diabetes mellitus reduced the modulatory role of the endothelium in mice,but therapeutic angiogenesis induced by bone marrow mobilization could be an effective treatment for ischemic limb disease in diabetic mice.

To investigate the relationship between diabetic macular edema (DME) and serum E-selectin level.
●METHODS: Totally 90 patients with diabetic retinopathy in our hospital from October 2009 to October 2013 were observed. Retrospective analysis of the correlation between macular edema degree and serum soluble E -selectin ( sE - sel ). Ninety patients with diabetic retinopathy were divided into two groups: DME group and non - DME group. The level of sE - sel and microalbuminuria (MA) of two groups were determined and compared.
●RESULTS: There was significant difference in MA, sE-sel levels of groups ( P < 0. 05). The value of diabetic retinopathy patients with sE - sel and MA, FBG were positively correlated ( r = 0. 728, P < 0. 05; r = 0. 651, P <0. 05).
●CONCLUSlON: Elevated levels of sE-sel is a risk factor for diabetic macular edema, and sE-sel was involved in the pathogenesis of diabetic microangiopathy.

OBJECTIVE: To study the antimicrobial effect of 11 kinds of oral Chinese patent medicines and to establish microbial limit test method for them. METHODS: Common method and culture medium dilution method and sticked filter membrane method were used to do the recovery test in order to validate the scientificity and feasibility of established method. RESULTS: Danqi piantan capsule showed strong inhibition effect on Staphylococcus aureus and Bacillus subtilis. Xinshuning tablet, Fuzheng mixture, Shenkangning mixture, Qingshen xiaodu oral liquid had antimicrobial effect on Staphylococcus aureus to some extent. Banlangen granule had antimicrobial effect on Bacillus subtilis. The effect can be eliminated by culture medium dilution method. CONCLUSION: The common method can be used for the microbial limit test of Jiaoou capsule, Zhike ningsou capsule, Rongdanshi granule, Sanjie mingmu capsule, Jiangzhi ruanmai tablet. Dilution method can be used for the microbial limit test of Xinshuning tablet, Fuzheng mixture, Shenkangning mixture, Qingshen xiaodu oral liquid, Banlangen granule, Danqi piantan capsule. The common method is suitable for all kinds of specified microorganisms.

Objective To find a new source to produce hESC lines.Methods D3 embryos with low morphological scores were cultured to blastocyst stage.Trophectoderm cells were separated from the ICMs by immunosurgery and isolated ICMs were cultured for 5-8 days on mitomycin-treated mouse embryonic fibroblasts(MEFs).Colonies derived from the ICMs were passed every 4-7 days and evaluated for cell surface markers including AKP,OCT-4,SSEA-4,SSEA-1,TRA-1-60,TRA-1-81,differentiation potentials and karyotypes.Results A total of 19 blastocysts were obtained from 130 embryos(quality score

Objective To investigate personality characteristics and its correlation with academic performance of vocational nursing students.Methods 153 nursing students were asked to filled out the questionnaire of Chinese College Student Personality Scale(CCSPS).The results were analyzed by 13.0 SPSS.Results Nursing students concentrated in the middle-up level in all the seven dimensions of the T-norm.The mean of directness,sensation and amiability were higer than the T-norm; The mean of tenaciousness and altruian were lower than the T-norm; There were different levels of correlation between academic performance and the four dimensions including directness,tenaciousness,rigorousness and amiability(P＜0.05).Finally only the dimension of rigorousness entered into the regression equation of academic performance.Conclusion Vocational nursing students tend to have ordinary personalities.The dimension of rigorousness is the major factor influencing vocational nursing students' academic performance.So it should be targeted to promote vocational nursing students' personality perfection.

It is important to pay more attention to students’ basic skills training and their comprehensive abilities cultivating in microbiology experiment teaching. Explorations and reforms in enforcing the students’ base and cultivating their abilities were carried out in order to improve teaching quality and train specialized talents with high quality.

Objective To explore the role of plasminogen activator inhibitor-1(PAI-1)in development of progressive fibrosis via the inhibition of extracellular matrix degradation,and to reveal the contributive role of PAI-1 in muscular dystrophy(MD).Methods Expression and cellular localization of PAI-1 protein were examined in frozen muscle specimens obtained via biopsy from 5 patients with duchenne muscular dystrophy(DMD),3 patients with becker muscular dystrophy(BMD),9 patients with congenital muscular dystrophy(CMD) and 4 cases with normal muscle by immunohistochemistry,double immunofluorescence and Western-blot analysis.Results PAI-1 was positive only in vascular endothelial cells of normal muscle.Both immunohistochemistry and Western-blot analysis showed that PAI-1 expression distinctly increased in most dystrophic muscles of MD than that in normal muscles.Double immunolabeling revealed that PAI-1 strongly expressed in cytoplasm and nuclei of regenerating muscle fibers,macrophages,macrophage infiltrating necrotic fibers.Some activated fibroblasts in endomysium and perimysium of DMD and CMD muscles were positive for PAI-1.Conclusions The functional consequence of overexpression of PAI-1 in dystrophic muscles is unknown but the elevated local expression of PAI-1 in diseased muscles of MD and their distinct distribution pattern provide evidence that PAI-1 participate in pathogenesis of MD.

Objective To explore the curative efficacy of astragalus injection on blood lipids and bone mineral density in patients with hemiplegia after ischemic stroke. Methods From January, 2014 to June, 2015, 116 patients with hemiplegia after ischemic stroke were col-lected and radomly divided into control group (n=54) and observation group (n=62). The control group received acupuncture based on con-ventional treatments, while the observation group received astragalus injection in addition. National Institutes of Health Stroke Scale (NI-HSS) and Ability of Daily Living Scale (ADL) were used to assess the neurologic impairment and the ability of daily living. The curative ef-ficacy and the levels of blood lipids and bone mineral density were observed. Results Compared with the control group, the curative efficien-cy increased (χ2=3.960, P<0.05). The score of NIHSS decreased (t=3.490, P=0.001), and the score of ADL increased (t=2.820, P=0.006). The levels of total cholesterol, triglyceride, low density lipoprotein cholesterol significantly decreased (t>4.190, P<0.001), however, the lev-el of high density lipoprotein cholesterol did not change (P>0.05). The densities in forearm, femur and Ward's area in the hemiplegia side in-creased (t>2.060, P<0.05). Conclusion Astragalus injection is effective on hemiplegia after ischemic stroke, which can increase the curative efficacy, alleviate the neurologic impairment, promote the ability of daily living, improve the blood lipids and increase the bone mineral den-sity.
