Objective To reseach the time point of the highest percentage of neural precursor cells derived from adipose stromal cells (ADSCs) in vitro, and to observe the ultrastructure features of neural precursor cells. Methods Used the β-mercaptoethanol to induce ADSCs to differentiate into neural precursor cells and neuron-like cells. The morphology of the uninductedcells and inducted cells were observed with inverted phase contrast microscope. The expression of nestin which was the marker of neural precursor cell in each group was detected using immunofluorescence staining method. The ultrastructural feature of cells which was induced for 3 hours were observed. Results The highest ratio of positive expression of nestin was 3 hours following induction,with the ratio ( 86.25 ± 4.82) %. There were many protuberance on the cell membrane under transmission electron microscopy.There were plenty of organelles in the neural precursor cells. The neural precursor cells had a large size nucleus,large nucleoplasmic index, much extended chromatin,and less condensed chromatin. The nucleus had double-layer nuclear envelope, more nuclear pore on the nuclear envelope. Conclusion The time point of the highest percentage of neural precursor cells derived from ADSCs is 3 hours,and the ultrastructral feature of induced neural precursor cells confirm that cells at this time point are in a state of split active period.

Objective To induce adult adult adipose-derived stem cells(ADSCs) in vitro to differentiate into neuronal-like cells,and to analyze the features of their cell morphology and ultrastructure. Methods Adipose stromal cells were obtained and amplified in vitro. Then make use of chemical induction to induce them. Observed ADSC and differentiation of cells in morphology and ultrastructure under inverted microscope and transmission electron microscopy. Immunocytochemistry to detection of Nestin, Neuron Specific Endolase( NSE) ,and glial fibrillary acidic protein(GFAP) expression in cells. Used Real-time PCR to detection of Nestin,GFAP gene mRNA expression before and after induction in ADSC. To observe the morphology and ultrastructure of the cells prior to and after induction under microscope and electron microscope. Results The morphology of ADSC was similar to fibroblasts ,and could be amplified stability within 10 passages in vitro. Some of the cells induced display a typical astrocyte-like cells in ultrastructure. Followed neuronal induction,astrocyte-like cells began to stain brightly for CFAP, Nestin. GFAP stained in both the cytoplasm and nuclei of astrocyte-like cells, but Nestin only stained in the cytoplasm. The peak positive expression rate within 14d following neuronal induction. The rate of positive expression cells was( 14.4 ± 3. 6) % for Nestin, (87. 3 ± 5. 3 ) % for GFAP. Then two kinds of protein expression remained the similar rate. The average relative concentration of GFAP and Nestin gene mRNA have significant statistical difference between ADSC and differented cells analyzed by Real-time PCR (P<0.05).The peak concentration of GFAP was within 20 d after induction,and GFAP was within 14 d after induction. Conclusion In the cytoplasm of adult adipose-derived cells possess Nestin genetic material,which is the marker of neural stem cell. The differential astrocyte-like cells have the typical morphology, ultrastructure and GFAP phenotype of mature astrocytes.

OBJECTIVE:To understand the public cognitive status about the adverse drug reaction(ADR),and provide refer-ence for improving the ADR reporting system. METHODS:Field to fill out and recycling questionnaire on the spot were conducted to investigate the cognition of ADR about 1 379 people from the Pearl River Delta,Eastern,Western and Northern region of Guangdong Province,and analyze related influential factors. RESULTS:Totally 1 500 questionnaires were sent out and 1 379 were effective with effective rate of 91.9%. Among the respondents,931(67.5%)could correctly answer the question of ADR concept, the correct rate showed lowest in the people lived in Northern region and with no less than 40 years old and low education;only 36.1% could correctly know the cause of ADR;only 388 (28.1%) knew the individuals can report ADR;723 (52.4%) thought hospital should be held responsible for ADR;once the ADR appeared,62.2% of respondents would choose to report to the hospi-tal. The main causes of discourage individual report of ADR were due to less know about where,how and which relevant depart-ments could report,and the report way was not convenient and the procedures were cumbersome. CONCLUSIONS:The public awareness of the ADR concept is not high and the enthusiasm of report is relatively low. Therefore,the propaganda of public aware-ness of ADR should be strengthened to encourage the public to participate in the ADR report actively,and broaden the channels of ADR personal report.

AIM: To investigate the change of myopic choroidal neovascularization treated by ranibizumab and evaluate their value in monitoring the effect of anti-vascular endothelial growth factor ( VEGF) therapy. ·METHODS: The study enrolled 30 patients ( 30 eyes ) diagnosed with myopic choroidal neovascularization. All affected eyes were treated with intravitreal ranibizumab 0. 05mL ( 10mg/mL ). Best corrected visual acuity ( BCVA ) , non-contact tonometer, ophthalmoscope, fundus fluorescein angiograph ( FFA ) and OCTA were evaluated monthly until 6mo. The changes of BCVA and central macular thickness ( CMT) were compared at 1, 3 and 6mo after treatment. ·RESULTS:All patients received an average of 1. 70±0. 65 injections. BCVA was 0. 96 ± 0. 17 ( LogMAR ) before therapy, and BCVA 1, 3 and 6mo after treatment respectively improved by 0. 23 ± 0. 09, 0. 34 ± 0. 07, 0. 38 ± 0. 11. The differences were significant ( t=5. 461, 8. 191, 8. 894; P<0. 05 ). Mean CMT decreased form 281. 07 ± 13. 72μm to 261. 33 ± 13. 13μm, 243. 47 ± 16. 65μm, 234. 73 ± 17. 52μm respectively 1, 3 and 6mo after treatment, showing significant differences (t=12. 007, 13. 360, 9. 531;P<0. 05). OCTA revealed a progressively smaller vascular lesion and reduction in capillary density. · CONCLUSION: Intravitreal ranibizumab for CNV secondary to pathologic myopia is effective and safe;OCTA is a noninvasive and time-saving new technology, and it also is a promising tool for clinicians to make preliminary diagnosis and assess treatment efficacy in the follow-up visits.

BACKGROUND: Several studies have confirmed that activation of intervertebral disc enzymes is closely related to matrix degradation. Matrix metalloproteinase and tissue inhibitor of metalloproteinase have been shown to exert important roles in the process of extracellular matrix degeneration in intervertebrel disk. Besides these two enzyme systems, whether other proteeses that exhibit degrading effects on extracellular matrix are involved in the intervertebral disk degeneration remains poorly understood.OBJECTIVE: To detect the cathepsin K expression in normal and degenerated human intervertebrel disc cells and investigate the correlation between cathepsin K and intervertebral disc degeneration.METHODS: Cathepsin K expression was detected in intervertebral disc tissue from 30 patients with lumbar intervertebral disc protrusion using immunohistochemistry SP method and ELISA. At the same time, the intervertebral disc tissue from 15 healthy adult cadavers and/or spine fracture patients was taken as control, Cathepsin K protein expression in normal and degenerated human intervertebral disc tissues were compared.RESULTS AND CONCLUSION: Cathepsin K expression was observed in normal and degenerated intervertebral disc tissues.The expression level was significantly higher in degenerated tissue than normal tissue (P ＜ 0.05). These findings demonstrate that Cathepsin K possibly participates in the intervertebral disc degeneration.
