Glaucoma is the first leading cause of irreversible blindness globally. China is one of the major developing countries and has the biggest burden of primary angle closure glaucoma (PACG) in the world. As the aged population grows in China, the amount of patients of PACG and"oecludable angle"will be increased consequently. China is facing a number of barriers in the prevention of glaucomatous blindness such as unbalanced alloeation of heahhcare resources, laek of evidence-based guidelines of glaucoma in accor- dance with Chinese situation, and sequential severe over-treatment. In this article, we reviewed the current mode of the prevention of glaucomatous blindness in China from the point of view of evidenee-based medicine and health economics, and provided several sugges- tions in further researehes and clinical works.

Objective To employ intraoperative discography to determine the injured intervertebral disc segments that can not be identified on the preoperative MRI in patients with cervical spinal cord injury without fracture and dislocation for confirming the responsible segments needing surgical decompression and fusion.Methods The study involved 85 patients with cervical spinal cord injury without fracture and dislocation treated from January 2007 to December 2011,among which sixteen patients had not been identified with the responsible segments by preoperative MRI.The average preoperative Japanese Orthopedic Association (JOA) score was (9.1 ± 1.8) points.There was no obvious fracture or dislocation of the cervical spine on preoperative X-ray film,CT and MRI,but all patients displayed high intense signal in cervical spinal cord on MRI T2 weighted imaging.Besides,MRI revealed hemorrhagic swelling of anterior cervical soft tissue in nine patients and cervical intervertebral disk hernia in all patients.Annulus fibrosus rupture of cervical intervertebral disc with contrast leakage in intraoperative discography of suspected injury segments in all patients under direction of C-arm X-ray machine was set as the injury criterion.The patients with pure ruptured discs received cervical discectomy,interbody fusion and titanium plate fixation.The patients associated with multilevel cervical intervertebral disc hernia or ossification of posterior longitudinal ligament underwent anterior cervical corpectomy,bone graft with titanium cageand titanium plate fixation of ruptured discs.Results Nineteen injured discs were identified eventually by discography,including 2 discs at C3/4,4 at C4/5,8 at C5/6 and 5 at C6/7.Moreover,anterior annulus fibrosus rupture with intact anterior longitudinal ligament was found in 11 patients.The follow-up lasted for (24.4 ± 10.0) months.JOA scores were (13.3 ± 1.5) points and (14.5 ± 1.6) points at two weeks and three months after operation,and (15.1 ± 1.5) points at the last follow-up,indicating a relevant improvement rate of 53％,68％ and 76％ respectively.Mean operation time was 110 minutes and blood loss was 120 ml.Three patients had pain on shoulder and back and one patient had hoarse voice,but all the patients were relieved in two weeks after conservative treatments.No serious complications,such as deep infection,deterioration of neurological dysfunction,vertebral artery injury or internal fixation failure were noticed intra-or post-operatively.Conclusion For the intradiscal rupture that is hard to be determined by the conventional imaging methods,intraoperative discography can be used as an auxiliary method of imaging diagnosis in early surgical determination of responsible segments for cervical spinal cord injury without fracture and dislocation.

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.

Objective To examine plasma levels of protease C1 inhibitor (SERPING1) in adult patients with latent autoimmune diabetes (LADA), and their clinical significance thereof. Methods The levels of SERPING1 were detected and compared between LADA, type 1 diabetes (T1DM), type 2 diabetes (T2DM) and healthy control groups. The correlation between plasma levels of SERPING1 and other clinical indicators such as age, disease course, glycosylated hemoglobin (HbA1c), fasting blood glucose (FPG), 2 h postprandial plasma glucose (2 hPG), fasting c-peptide (FCP) and 2 h postprandi-al C peptide (2 hCP) was analyzed. Multi-factor regression analysis and receiver operating characteristic (ROC) were used to evaluate the predictive effect of SERPING1 in LADA at the early stage. Results The level of SERPING1 was significantly higher in LADA group than that of T2DM group and control group (P < 0.05). There was a negative correlation between SERPING1 and FCP, and a positive correlation between SERPING1 and HbA1c, FPG and 2 hPG (P<0.05). There were no significant correlation between SERPING1 and age, disease course and 2 hCP. FCP was analyzed by regression equation (P<0.05), and which was the main influence factor of the plasma level of SERPING1. The area under the ROC curve (AUC) of SERPING1 was 0.613 (P<0.05), 95%CI 0.514-0.712. The optimal cut-point of SERPING1 for early prediction of LADA was 289.71 mg/L, and the sensitivity and specificity were 69%and 48%respectively. Conclusion SERPING1 combined with other indicators will be useful for identifying LADA from T2DM at the early stage.

Objective To evaluate the feasibility and effectiveness of percutaneous intraductal radiofrequency ablation (RFA) in treating biliary stent stenosis. Methods A total of 43 cases with biliary obstruction caused by biliary stent stenosis were enrolled in this study. Through percutaneous transhepatic pucturing of biliary duct, an EndoHPB catheter was placed in the stenotic site of the biliary stent, which was followed by RFA treatment. After RFA, biliary drainage catheter was reserved. The drainage catheter was removed when angiography confirmed that the stent was patent. Results Cholangiography showed that the biliary stent became patency after RFA in all patients. No procedure-related complications occurred. After RFA, the median patency time of the stenotic biliary stent in survival patients was 107 days (12-180 days). Conclusion The results of this preliminary clinical study indicate that percutaneous intraductal radiofrequency ablation has excellent effect and safety for the treatment of biliary stent stenosis, although more reliable and randomized controlled trials are needed before its effect and safety can be further proved.

Objective To establish rat model of type 2 diabetes through a single subcutaneous injection of lipopolysaccharide which induced chronic inflammation.Methods The male Wistar rats(n = 30)were randomly divided control group (n = 10)and model group (n=20).Model group with LPS (300 μg·kg-1 ·day-1 )subcutaneous injection of eight weeks,rats in control group received isometric stroke-physiological saline solution injection in the same way.The changes in appearance,weight and fasting blood glucose (FBG)of rats were observed every week.At the end of the 8th week,thelevels of tumor necrosis factor a (TNF-α), interleukin-1(IL-1),interleukin-6 (IL-6),monocyte chemotactic protein-1(MCP-1)and fasting insulin(FINS)were measured.Oral glucose tolerance test (OGTT)and insulin release test(IRT)were also performed.The successful rat model was determined by the standards that FBG was ≥11.1 mmol/L.Results Model group rats reached the standard of type 2 diabetes after six weeks of LPS injection.Model group blood sugar is significantly higher than the control group (P <0.05).In addition,model group′s expression level of inflammatory cytokines in serum TNF-α,IL-1,IL-6,MCP-1 and FINS were significantly higher than control group (P <0.05).Oral glucose tolerance test,blood glucose levels higher than normal in model group,the insulin peak is lower than the normal group (P <0.05).Conclusion The success of establishing the animal model of type 2 diabetic rats which were injected of low dose of LPS by subcutaneous may be provide certain help for the etiology of diabetes research.
