objective To evaluate the therapeutic efficacy of surgical and nonsurgical treatment and the clinical factors affecting the efficacy in traumatic optic neuropathy. Methods To analyse retrospectively the efficacy of recovery of visual acuity in 40 cases of traumatic optic neuropathy after treatment with transnasal endoscopic sphenoethmoidal optic canal decompression (28 cases) and drug therapy (12 cases). Results No significant difference existed between the therapeutic efficacy of surgery and that of drug therapy in patients with the visual acuity of LP～0.02. In surgery group,the therapeutic efficacy of the patients with visual acuity of LP～0.02 was better than that of the patients with no LP.The therapeutic efficacy of patients with duration shorter than seven days before sutgery is better than that of patients with duration longer than seven days. Conclusions The patients with serious traumatic comperssive optic neuropathy should not be treated with decompressive surgery and should not delay to at most seven days after injury.With or without the visual acuity of light perception of the affected eye surgery is usually an important factor affecting the therapeutic efficacy.

Objective To study the expressions of B7-H1 and PD-1 which are costimulatory molecules in the pathogenesis of chronic hepatitis B (CHB). Methods The heparin anticoagulant blood samples from 11 CHB patients and 16 healthy controls were collected. The expressions of B7-H1 and PD-1 on myloid dendritic cells (mDC) and T lymphocytes in the peripheral blood were analyzed by flow cytometry. The data comparison was done by t test. Results The expressions of B7-H1 on CD3~+ ,CD4~+ , CD8~+ T lymphocytes and mDC in CHB patients were (40. 69± 14. 49)%, (42. 84 ±11. 19)%,(33. 48±14.07)% and (16. 60±4. 04) % , respectively, and those were (14. 66±10. 11) % , (4. 62±3.84)%, (1.89±2.31)% and (0. 49±0. 37)% , respectively in healthy controls. The expressions of B7-H1 on T-lymphocytes and mDC in CHB patients were significantly higher than those in healthy controls, and the differences were significant (t=-2.884,t=-10.894, t=-7.378, t=-13. 182,respectively; all P<0. 05). The expressions of PD-1 on CD3~+ , CD4~+ and CD8~+ T lymphocytes in CHB patients were (12. 45±6. 36)%, (11. 42 ± 6. 20)% and (13. 03± 6. 71) %, respectively, and those were (7. 80±3. 53)%, (7. 12±2. 60)% and (7. 88±3. 74)% , respectively in healthy controls.The expressions of PD-1 on T lymphocytes in CHB patients were significantly higher than those of the healthy controls, the differences were significant (t = -2.323, t =- 2. 355, t =- 2. 439,respectively) all P<0. 05). Conclusion The expressions of B7-H1 and PD-1 on T lymphocytes and mDC in CHB patients are higher than the healthy people.

Objective To guide new nurses to establish positive and correct occupational self-concept, enhance occupational identity and delay job burnout by adding traditional culture education in the standardized training for newly recruited nurses. Methods Randomly selected 56 new nurses of our hospital in recent years as research objects. 28 nurses enrolled in 2013 formed the experimental group and 28 nurses enrolled in 2014 formed the control group. The experimental group focused on nurses themselves. In the 10-month standardized training, 30 class-hour traditional culture education was added and more than 180 times of social practices were conducted; for the control group, only standardized training was carried out. Effects before and after, all subjects were examined occupational self-concept and desert jobs rate after work 2 years. Results The occupational self-concept of the experimental group tended to reach a positive level, which was (33.14±2.15) points, obviously higher than that of the control group, which was only (30.57 ± 3.03) points. Therefore, the difference was statistically significant(t=3.703 4,P<0.01). In terms of dimensions of comprehensive self- concept, employee relationships and communication ability were (4.92 ± 0.50), (6.34 ± 0.54), (5.87 ± 0.44) points in the experimental group and (4.40 ± 0.63), (5.89 ± 0.77),(5.55 ± 0.64) points in the control group, the experimental group had significant improvements (t=3.458 1, 2.561 9, 2.206 4, P<0.01). Comparing the separation rates of the two groups after two years, the difference was not statistically significant (P>0.05). Conclusions Adding traditional culture education in the standardized training for newly recruited nurses plays a positive role in promoting their occupational self-concept.

BACKGROUND: Studies have found that chondroitin sulfate proteoglycans degradation with chondroitinase canpromote the migration of Müller cells on the retina, but whether it could promote the migration of adipose-derivedmesenchymal stem cells in retinal degeneration rats is unclear.OBJECTIVE: To investigate the effect of chondroitin sulfate proteoglycans degradation with chondroitinase on adipose-derived mesenchymal stem cell treatment for retinal degeneration in rats.METHODS: Human adipose-derived mesenchymal stem cells were isolated and cultured. A retinal degeneration ratmodel was established followed by administration of adipose-derived mesenchymal stem cells+chondroitinase into thesubretinal space. The migration of adipose-derived mesenchymal stem cells and retinal cell apoptosis in rats aftertransplantation were observed.RESULTS AND CONCLUSION: The human adipose-derived mesenchymal stem cells could be successfully cultured.The labeling rate of BrdU to the human adipose-derived mesenchymal stem cells was more than 90.0%. At 7 days aftermodeling, the outer nuclear layer of the retina was collapsed, and a large amount of photoreceptor cells were dissected.The outer nuclear layer was attached to the Bruch''s membrane, and the retina was arched. The central retina andperipheral retina were damaged. In normal rats, the retinal layers were clear, and the photoreceptor cells arrangedregularly; and the retinal pigment epithelium was complete. The migration rate of adipose-derived mesenchymal stemcells in adipose-derived mesenchymal stem cells+chondroitinase group was higher than that in adipose-derivedmesenchymal stem cells group (P < 0.05). There was no significant difference in the apoptotic rate of retinal cellsbetween the two groups (P > 0.05). These experimental findings show that chondroitin sulfate proteoglycans degradationwith chondroitinase can enhance the migration ability of human adipose-derived mesenchymal stem cells on the retina.

BACKGROUND:Neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine can induce the clinical, biochemical and pathological characteristics similar to those observed in primary Parkinson’s disease. OBJECTIVE:To observe the effects of repetitive transcranial magnetic stimulation on the proliferation of endogenous neural stem cells of Parkinson’s disease model mice and the mood change.
METHODS:A total of 72 male C57BL/6J mice were randomly divided into four groups:normal saline group, Parkinson’s disease model group (model group), sham-repetitive transcranial magnetic stimulation group (sham group) and repetitive transcranial magnetic stimulation group. The mice received 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine injection×4 to establish acute Parkinson’s disease models. The mice in the normal saline group were injected the same volume saline. And 24 hours after the last injection of 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine, the mice in the repetitive transcranial magnetic stimulation group received five trains of repetitive transcranial magnetic stimulation, 1 Hz for 25 seconds, at an intensity of 1 Tesla daily for 1, 3, 7 consecutive days. Sham group mice were not exposed to the magnetic field. No treatment was performed in the mice of model group. The mood change was evaluated using the elevated-plus maze testing before and after repetitive transcranial magnetic stimulation treatment. The change in expression of nestin in the subventricular zone was observed by using immunohistochemical technique.
RESULTS AND CONCLUSION:(1) Elevated-plus maze testing:There was no statistical significance about percentage of opening arm time accounting for total time among groups and at different time points in each group, but after stimulation, the percentage of opening arm time accounting for total time showed a declined tendency. (2) The results of nestin immunohistochemical staining:Compared to the normal saline group, the number of nestin-positive cells of the model group was increased at days 3 and 7, and there was no statistical significance in the number of nestin-positive cells between model group and sham group;Compared to the sham group and model group, the number of nestin-positive cells of repetitive transcranial magnetic stimulation group were evidently increased;The proliferation of endogenous neural stem cells was time-dependent, endogenous neural stem cells exhibited outward migration gradual y along the certain way, and some cells were able to migrate to the corpus cal osum at day 3, and even to the cerebral cortex at day 7. Repetitive transcranial magnetic stimulation can promote the endogenous neural stem cells in a time-depended manner.
