Objective:To investigate the expression of CXCL9 in oral submucous fibrosis (OSF) as well as oral lichen planus (OLP) and its role in the inflammatory and immunological reaction. Methods:The expression of CXCL9 was examined in 66 OSF specimens,17 OLP specimens and 10 normal buccal mucosa tissues by immunohistochemistry,and the protein level of CXCL9 were detected by Western blotting.Results:43 (65.2%) cases of OSF and 16 (94.1%) cases of OLP showed positive immunoreactivity for CXCL9 in the cytoplasm of inflammatory cells and endothelial cells. All normal buccal mucosa tissues stained negative for CXCL9. The expression levels of CXCL9 in OLP and OSF were significantly higher than that of normal controls,and the expression level in OLP was significantly higher than in OSF(?2= 4.20,P

AIM: To analyze the reasons of low vision and blindness in elderly patients and the application of optical aids in rehabilitation.METHODS: Totally 87 elderly patients which had 74 cases of low vision,13 cases of blind,including 53 males and 34 females.Routine internal and external eye examinations should be performed,and special removal examinations should be performed if necessary.Both refractive correction,and try with far and near optical aids,check after wearing a typoscope distant and near vision,distant vision ≥0.05 out the blindness,distant vision ≥0.3 out the disability.Near vision ≥ 0.5 was valid,<0.5 was invalid.RESULTS: Among 87 elderly patients with low vision,high myopia was the leading cause of blindness,followed by macular degeneration,cataracts,glaucoma and diabetic retinopathy.The visual acuity after refractive correction increased ≥ 2 lines in 62 cases (71%),visual acuity was not correct or corrected for ≤ 1 of 25 cases (29%).With aids,far visual was ≥0.3 of the 70 cases (80%),≥0.05 in 10 cases (11%),<0.05 in 7 cases (8%),residue removal rate of 92%.With reading glasses near and near visual acuity was >0.5 effective in 60 cases (69%),<0.5 ineffective in 27 cases (31%).Typoscope was often used in 58 cases,not often used 18 cases,11 cases rarely used or give up.CONCLUSION: High myopia is the leading cause of low vision and blindness in the elderly,followed by macular degeneration.The application of visual aids is still reliable and economical and effective treatment method,patients should be encouraged to use visual aids to improve the utilization rate of aids,so as to improve the quality of life of patients.

OBJECTIVETo explore the effect and mechanism of cinnabaris and realgar in promoting awake effect of endotoxin- induced brain injury rat applied with Angong Niuhuang Wan.

METHODNormal rats implanted cortical electrode in advance were divided into 6 groups: control, model, the Angong Niuhuang Wan (AGNH, 0.4, 0.2 g · kg(-1)), the Angong Niuhuang Wan without cinnabaris and realgar (QZX-AGNH, 0.32, 0.16 g · kg(-1)). Rats in the control and model groups were given distilled water. After three days of intragastric administration, the brain injury model was injected with endotoxin through tail vein. Then trace electro-corticogram (EcoG) 1-6 h after LPS injection, and compare the power and relative power of beta (β) and delta-waves (δ) at 6 h of these groups. The content of acetylcholine (Ach) and the affinity of M-receptor (M-R) in cortex and brainstem were detected by alkaline hydroxylamine colorimetric method and radioactive ligand binding assay, respectively.

RESULTAGNH (0.4, 0.2 g · kg(-1)) could increase the power and relative power of β and AGNH (0.4 g · kg(-1)) showed better action on brain electrical activation. QZX-AGNH showed weak effect on it. AGNH (0.4 g · kg(-1)) could increase the affinity of M-R in cortex and the content of Ach in brainstem. The action of QZX-AGNH was not obvious.

CONCLUSIONIn endotoxin-induced brain injury rats, AGNH can raise the cholinergic system function of cortex, and strengthen the uplink of cortex activation of brainstem cholinergic system, improve the level of cortical activity and enhance the activation of EcoG to promote the body's awakening. QZX-AGNH show weak effect. Cinnabaris and realgar play an important role in promoting awake effect in endotoxin-induced brain injury applied with Angong Niuhuang Wan. The mechanism may be related to cortical and brainstem cholinergic system function.

Objective To evaluate the intensity-modulated radiation therapy(IMRT)for the whole pelvis in the treatment for cervix cancer with the method of ionization chamber verification and fluence map verification.Methods IMRT plan was designed with Pinnacle 7.0 inversed treatment planning system,and the planning parameter was copied to the solid water phantom.The dose of the reference points in the phantom was calibrated with ionization chamber,and compared with those in IMRT plan.Then the gantry angle was set as 0 degree.The solid water phantom was irradiated with film,and the actual fluence maps were obtained 2cm below the phantom surface,and then the delivered films were compared with those fluence maps in plan.Results The error percentage at 4 points was less than 3% in absolute dose calibration,at 2 points was less than 5%,at another 2 points was less than 5%,at 1 point was over 10%,and at another 1 point was over 15%.It was found that the last two calibrated points were set in a region with a high dose gradient,resulting in high error.In fact they were impertinent.So another two points were chosen in uniformity area of dose distribution.The percentage of error were both less than 3%.The fluence maps between films and plan were consistent.Conclusion It is feasible to evaluate IMRT plan for whole pelvis in the treatment of cervix cancer with the method of ionization chamber verification and fluence map verification.The results can meet the clinical requirement.
