Objective To analysis the flash electroretinogram (FERG) of diabeic retionpatby patients. Method 90 cases of DR patients were selected. According to the partial signs and the overall symptoms, the patients can be divided into three syndromes - dry heat by yin deficiency, deficiency of both qi and yin, deficiency of yin and yang. FERG were detected. Result There was close relation between the occurrence and development of DR and the evolution of the syndrome from yin deficiency to yang involved by deficient yin. Retina actional potential will change along with the change of syndrome. Conclusion The retina actional potential which recorded by FERG can be used as an objective criterion of syndrome differentiation, thus we can establish a diagnosis and treatment system of DR.

BACKGROUND:Bone marrow is the main source of mesenchymal stem cells(MSCs)at present,but its application has been limited,because of some reasons such as inconvenience of isolation,and the quantity of cells decreases with human increased age.Umbilical cord as a new source of MSCs has been widespread concerned recently.OBJECTIVE:To explore the approach of isolating and culturing MSCs from Wharton's jelly of human umbilical cord,and the methods of identifying the surface antigens and the differentiation potential.METHODS:MSCs were isolated and amplified via tissue-cultivation,and cultured by FasGrow medium.Morphology of MSCs from Wharton's jelly of human umbilical cord was observed under the optical microscope.Its immunophenotypes were detected using immunohistochemistry.The differentiation of MSCs into the osteoblasts was determined utilizing Gomori calcium-cobalt alkaline phosphatase staining,von Kossa calcium node staining,and tetracyclinefluorescence labeling.The differentiation of MSCs into the adipocytes was detected using oil red O staining.RESULTS AND CONCLUSION:MSCs were easily obtained from Wharton's jelly of human umbilical cord via the proposed approach.The primary cells grew up to 70%-80% confluence after 12-16 days of culture,and meanwhile the undifferentiated state was maintained and proliferation was stabilized after passage.The cell cycle of double increase was about 2 days,and proliferation in vitro reached twenty generation above.Surface antigen analysis showed that CD44,CD105,CD133,MHC-I were positively expressed,while CD34,CD45 were negatively expressed.Experiments of differentiation in vitro indicated that the obtained cells were capable of differentiating into fat,osteoblast and nerve-like cells.

OBJECTIVE To explore the clinical effect of tonsil temperature-controlled bipolar radiofrequency ablation technology in the treatment of snoring and mild-moderate-obstructive sleep apnea hyponea syndrome(OSAHS). METHODS Forty-six patients were selected,of which 17 were snoring and 29 were mild-moderate-obstructive sleep apnea-hyponea syndrome cases. Tonsil temperature-controlled bipolar radiofrequency with varying probes was used for all patients. RESULTS A follow-up of 6～18 months was carried out. 9 of 17 snoring cases resulted in recovery. The procedure was effective in 6 cases and not effective in 2 cases. 15 of 29 OSAHS cases resulted in recovery. The procedure was effective in 10 cases and not effective in 4 cases. Overall successful rate was 86.9 %(40/46). The size of tonsils, apnea hyponea index(AHI),snoring scale and Epworth sleepiness score(ESS)were significantly decrease dafter operation(P

Objective To explore the influence of whole-course individualized nursing intervention on treatment compliance among intractable epilepsy children with ketogenic diet therapy.Methods 80 intractable epilepsy patients with ketogenic diet therapy were divided into the control group and the experimental group with 40 cases in each group.The routine nursing was given to the control group.On basis of routine nursing,whole-course individualized nursing intervention was given to the experimental group.The investigation was carried out before and after intervention in two groups by using self-designed questionnaire.The treatment compliance and therapeutic effect were compared between two groups.Results The treatment compliance and therapeutic effect were significantly alleviated in the experimental group compared with the control group in the third,sixth and twelfth months.Conclusions The whole-course individualized nursing intervention can improve the parental awareness of the disease,enhance their confidence and determination to adhere to the treatment,improve their treatment compliance,thereby improve the effect of treatment.

ObjectiveTo investigate the feasibility and optimal condition of isolation,purification and expansion of mesenchymal stem cells(MSCs) derived from human umbilical cord blood in vtro.MethodsHuman umbilical cord blood(HUCB) was collected from full term deliveries scheduled,all samples were obtained sterilely with 20 U/ml preservative free heparin.The cord mononuclear cells were isolated with lymphocyte separation medium(density 1.077 g/ml),purified and expanded with MesencultTM medium and acidic environment to produce adherent layer.The surface antigen expression of MSCs was detected with flow cytometry.ResultsThe HUCB-derived mononuclear cells,when seeded in specific medium,gave rise to adherent cells,which exhibited either an osteoclast or mesenchymal-like phenotype.After passage 3,these cells were able to be purified and expanded.6.6×105 primary MSCs reached a number of 9.9×10<>sup8 after 10 expanded passage.Flow cytometry showed that MSCs did not express antigens CD34,CD11a and CD11b,but express strongly CD29 and weakly CD71,which was identical to human bone marrow-derived MSCs.ConclusionMSCs in HUCB can be cultured and expanded in vitro,and could be a source of stem cells for experimental and clinical application.
