Objective: ①To detect the concentrations of interleukin 1?(IL 1?) and prostaglandin E 2 (PGE 2) in periapical exudates in the patients with acute or chronic periapical periodontitis; ② To examine their correlations with clinical and radiographic findings of the involved teeth.Methods: The volume of periapical exudates was quantified using the standard paper point sampling method; the concentration of IL 1? and PGE 2 was detected using enzyme linked immunosorbent assay(ELISA) or radioimmunoassay(RIA) in 40 cases with acute and in 40 with chronic periapical periodentitis. Results: ①The volume(?l) of the exudates in the cases with acute periapical periodontitis and chronic were 27.10?15.70 and 3.12?2.88( P

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.

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.

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.

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.

Objective To investigate the dosage and safety of insulin aspart in continuous subcutaneous insulin infusion plus oral antidiabetic drugs for the treatment of hyperglycemia in elderly hip fracture.Methods Patients with hip fracture and hyperglycemia who required insulin pump therapy were divided into 2 groups according to age:elderly group (patients aged over 65 years,n=42) and non-elderly group (patients aged under 65 years,n=43).All patients were treated with insulin aspart in continuous subcutaneous insulin infusion plus oral antidiabetic drugs combined with diet therapy.Dosages of aspart insulin and adverse effects were compared between the two groups.Results There were no significant differences in basic aspart dosage and additional premeal dosage between elderly and non-elderly groups [(0.29±0.09) IU/kg vs.(0.30±0.07) IU /kg,(0.27±0.09) IU/kg vs.(0.27±0.07) IU/kg,both P>0.05].The incidences of hypoglycemia with and without symptoms in elderly versus non-elderly groups were 4.8% vs.4.7% and 14.3% vs.18.6%,which had no significant differences between the two groups (P>0.05).Hypoglycemia accompanied by consciousness disorders,allergy,nonhealing and slow healing wounds were not found in the two groups.The ratio of oral antidiabetic drugs including metformin,glimepiride,and glycosidase inhibitor had no differences between the two groups.Conclusions Aspart insulin in continuous subcutaneous insulin infusion is effective and safe in the treatment of acute severe hyperglycemia in elderly patients with hip fractures when combined with diet therapy and oral antidiabetic drugs.

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.
