Objective To observe the diameters of macular hole and destroyed boundary line between inner and outer segment (IS/OS) of the photoreceptors and the correlation with the visual acuity in patients with idiopathic macular hole(IMH). Methods The clinical data of 39 eyes (37 patients) with IMH were retrospective analyzed. All the patients had undergone the examinations of visual acuity (Snellen chart), intra-acular pressure, ocular fundus (indirect ophthalmoscope), and Fourier-domain optical coherence tomography (FD-OCT) whose speed was 27 000 A scan/s, area was 6.0 mm×6.0 mm, and the mode was 512×128. The diametres of macular hole and destroyed IS/OS, and the correlations with visual acuity were detected. Results The mean IogMAR was 0.99±0. 44 (ranged from 0. 15 to 2.00), the mean diameter of macular holes was (942.0± 348. 4)μm(ranged from 171 to 1491 μm), and the mean diameter of IS/OS disruption was (1870. 35±673.2) μm(range from 463 to 3176 μm). There was a significant correlation among the diameter of the macular hole, the diameter of the IS/OS disruption, and IogMAR in IMH (P= 0. 038, 0. 002, 0. 000). In eyes with closed macular hole after surgery, the IogMAR and the diameter of the IS/OS disruption had a significant decrease. Conclusion Using FD-OCT the photoreceptor changes can be visualized in vivo. The abnormality in the IS-OS boundary line appears to be involved for a much larger area beyond the macular hole itself, and persists there with small size even after the maeular hole closure surgery.

Objective To investigate the cognition, self-management and quality of life of osteoporosis in elderly patients, and to provide the basic theory for health education in elderly patients with osteoporosis.Methods 565 elderly patients with osteoporosis in our hospital from May 2012 to Mar.2015 were enrolled.The cognition, health beliefs, self-efficacy and quality of life were investigated by questionnaires and analyzed by Microsoft Office Excel 2007.Results 565 osteoporosis patients, the symptom score was (15.6±2.0), and the score was lower in sporting knowledge (4.3 ± 1.8) than in calcium knowledge (5.7 ± 1.5) (t=2.784, P=0.011).Health beliefs score was (139.0±9.6), containing exercise benefits score of (21.5±3.1), exercise barriers score of (13.8±3.9), susceptible score of (19.4±4.2), serious score of (18.8±4.4), health motivation score of (25.0±3.0), calcium intake benefits score of (20.7±3.5) and calcium intake disorder score of (19.8 ± 4.0).Self efficacy score was (63.7 ± 19.4), containing exercise efficacy score of (58.6 ±18.7) and calcium efficacy score of (69.2± 18.5).Quality of life score included the general health (16.5± 2.9 score), social function (5.8 ± 1.3 score), vitality (14.8 ± 3.2 score), mental health (20.7± 4.2 score), physiological function (20.5 ± 4.1 score), physiological role limit (6.3 ± 1.6 score), emotional role limit (5.1 ± 1.3 score) and body pains (4.3 ± 1.8 score).Conclusions The score in cognitive function is low in elderly osteoporosis patients.It's useful to improve elderly osteoporosis awareness and quality of life by carrying out relative education.

0. 05). No significant difference was found in maternal and neonatal complications between the ANCA( + ) and ANCA(－) subgroups in S-PE subjects. But those 4 cases who developed renal function insufficiency patients were ANCA( + ). Conclusions ANCA might be associated with renal diseases in preeclampsia women, and further studies is required to determine whether ANCA is involved with the pathogenesis of preeclampsia.

In recent years, the prevalence of cardiovascular disease (CVD) in China has been increasing year by year, and it has become a major public health concern. The prevention and control of chronic CVD is inseparable from effective early screening. However, due to the imbalance in the level of economic and social development in various parts of China, the universality and accessibility of screening in some areas still need to be improved. The fundus retinal blood vessel is the only vessel in the whole body that can be directly observed. Studies have found that its morphological and functional changes are related to the occurrence and development of many CVD, and it has the potential to become a tool for assessment and prediction. This review intends to introduce the research progress of retinal blood vessels in the evaluation and prediction of cardiovascular disease in recent years.

Objective To explore the changes of etiology and mortality of upper gastrointestinal bleeding (UGIB) in the last 20 years in Guangdong region. Methods A total of 3140 UGIB cases diagnosed in Guangdong General Hospital from January 1990 to October 2009 were analyzed with retrospective analysis. Groups were divided according to admission chronological order and age to analyze the causes of UGIB to get the trend of changes and influencing factors. Results UGIB occurred more in men than in women, the gender ratio was 2. 5∶1. There was no significant change in gender composition between the first and later 10 years. Peptic ulcer bleeding (PUB) was the main cause of UGIB in young and middle-age patients (age<60 years), especially duodenal ulcer (DU)bleeding (45. 0%) , and secondary was acute gastric mucosal lesion ( AGML) (16. 6%). While in elder patients group (age≥60 years), the main cause of UGIB was AGML (40. 5%), the frequency was significantly higher compared with the young and middle-age group (40. 5% vs 16. 6%,P<0. 01).Compared the first 10 years with the later 10 years, the occurrence rate of PUB was overall in downward trend (57. 4% vs 42. 8%, P<0.01), of which DU and compound ulcer(CU) bleeding reduced significantly (DU: 43.8% vs 27.7%, P<0. 01 and CU: 7.7% to 5.5%, P<0. 05). While the incidence of gastric ulcer (GU) (7.4% vs 8. 1% ,P>0. 05) and esophagogastric variceal bleeding (EVB) (11. 7% vs 12. 9%, P>0.05) remained stable. The occurrence of AGML bleeding significantly increased than before (32. 4% vs 18. 8%,P<0. 01), and became one of the most important causes of UGIB. Conclusions PUB is still the most important cause of UGIB in Guangdong region. AGML becomes another important cause of UGIB in elder patients, which may relate to the increasing use of non-steroidal anti-inflammatory drugs (NSAIDs), anti-platelet and antineoplastic medicine.

OBJECTIVETo explore the expression of hepatitis B-virus X gene (HBX) in adenoid cystic carcinoma (ACC) and determine its clinical significance.

METHODSBetween June 2008 and October 2012, in-hospital patients with salivary gland tumors who were treated at the Department of Oral and Maxillofacial Surgery, Affiliated Stomatology Hospital of Kunming Medical University, were enrolled to this study. HBeAb-positive patients were defined as those exposed to hepatitis B virus (HBV) or harboring persistent HBV infection regardless of being HBeAg positive or negative. According to the pathological results, all patients were divided into ACC group and control group. Immunohistochemical staining and polymerase chain reaction (PCR) were used to detect HBX expression in ACC group and control group.

RESULTSHBX expression was mostly detected in the cytoplasm of ACC cells. Minimal HBX expression was detected in the nucleus. HBX expression was significantly higher in ACC than in Warthin's tumor. A significant difference was observed between the two groups.

CONCLUSIONHBX is expressed in ACC and may be associated with the development of ACC. HBX might serve important functions in the carcinogenesis and development of ACC.
