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 study the adiponectin mRNA expression in omental adipose tissue of type 2 diabetes. Methods RT-PCR method was used to examine the adiponectin mRNA expression. Fasting levels of BG,TG,TC,HDL-C,LDL-C of all the subjects were checked and their blood pressure,height,weight,waist circumference,hip circumference were measured to calculate BMI,WHR. Results The adiponectin mRNA expression in omental adipose tissue was decreased in diabetes group versus non-diabetes group (P<0.05),and negatively correlated with WC,TG,FBG,WHR(P<0.05). Conclusions Type 2 diabetic patients show lower expression of adiponectin mRNA in omental adipose tissue than that of non-diabetic control.WC,TG,FBG, WHR and course of disease are correlated with adiponectin mRNA expression and insulin resistance

In this paper, 29 endophytes were isolated from different organs and tissues of Lycium barbarum of Ningxia by tablet coating method, 18 of them was fungi, and 11 of them was actinomycetes. The endophytes quantity in the different tissues were leaves > flowers > roots >fruits; The hydroxyl radical scavenging activities of 11 endophytes were investigated by Fenton reaction, and total antioxidant capacities of them were examined by a. total antioxidant capacity test kit; culture features and strain-specific sequence analysis were employed to explore the diversity of the 11 endophytes. The result showed that 5 fungi and 6 actinomycetes that having antioxidant activity could be phylogenetically classified into 3 genera, 3 genera and 3 families, respectively. The total antioxidant capacity and hydroxyl radical scavenging activity of the 11 endophytes showed distinct difference. The antioxidant activity of Aspergillus were stronger, among which total antioxidant capacity of fL1 was (188.5 ± 0.549) U · mL⁻¹ and the IC₅₀ was 0.3 mg · L⁻¹; the IC₅₀ of strain fL1 was 0.42 mg · L⁻¹ and the total antioxidant capacity of fL9 was (113.63 ± 1.021) U · mL⁻¹, all of them were stronger than the positive control Vit C. The experimental results indicated that endophytic fungi of L. barbarum of Ningxia have a great developing and application prospect for the development of antioxidant agent.
