Internal limiting membrane ( ILM) peeling is commonly used in the operation of idiopathic macular hole ( IMH ) surgery. The success of ILM peeling has been greatly improved with the assistance of vital dyes. Currently, several kinds of vital dyes such as indocyanine green ( ICG ) , brilliant blue G ( BBG ) are applied in the ILM staining. However, all of the vital dyes have potential toxicity and side effects on the retina. In recent years, many kinds of dyes and staining improved emerge in endlessly. This paper reports the progress in the application of different colorants in the operation of IMH.

Objective To investigate the value of detecting HEART score and HEARTS3 score in risk stratification and prognosis of acute coronary syndrome (ACS) in patients with non-ST segment elevation chest pain in emergency department (ED).Methods Clinical data of case-control retrospective study of 775 patients with non-ST segment elevation chest pain in ED were collected from July 2011 to March 2015.The patients were estimated and risk stratification was made with HEART score and HEARTS3 score.After follow-up visiting by telephone for 30 days,outcomes were found to be ACS and myocardial infarction (MI).And the patients were categorized with score into low,intermediate and high risk groups.The correlation between the ACS and risk score in three groups was analyzed.Comparison of capability of performance in predicting 30-day ACS between the HEART score and HEARTS3 risk score.Statistical analyses were performed using SPSS13.0.Enumeration variables were expressed as percentage.For comparison of predictive value of the two sets of scores,area under the receiver operating curve (auROC) was calculated and compared by Z test.Results There were 92 cases with 30-day ACS.The rate of ACS had a trend of increase with increase in HEART score and HEARTS3 score.The patients with higher scores of HEART and HEARTS3,higher incidence of ACS in 30 days.Especially,the high-risk patients with score≥7 of HEART score and≥8 of HEARTS3 score had higher rate of ACS.And there was significant difference in predicting high-risk patients between two sets of scoring (P ＜ 0.05).The HEARTS3 score outperformed the HEART score as determined by comparison of areas under the ROC curve for MI (0.952 vs 0.813;P =0.028),30-day ACS (0.913 vs.0.815;P =0.034).Conclusions HEART score and HEARTS3 score both can be used to evaluate and perform risk stratification for non-ST segment elevation chest pain patients in ED.But HEARTS3 score can more precisely stratify high-risk patients with chest pain for 30-day ACS.

Objective To investigate the changes of serum apolipoprotein A-I and its clinical significance to acute respiratory infection.Method Totally 44 patients with acute respiratory infection were divided into three groups according to various concentration of Serum apolipoprotein A-I.They were procaleitonin(PCT)＜0.5 ng/ml group,0.5 ng/ml≤PCT＜2 ng/ml group and PCT≥2 ng/ml group.We measured apolipoprotein A-I,C-reactive protein,procalcitonin and albumin within 24 hours after admission.Results With the increase of serumPCT,the production of ApoA-I and albumin were down-regulated,while CRP up-regulated.Conclusions Apolipoprotein A-I has a sound relationship with the acute respiratory infection.It can be used as one of the diagnostic criteria in severe infection patients who have disorders of lipometabolism.

Objective To find out the status of prevention and control of iodine deficiency disorders and evaluate the iodine nutritional status of Jinan residents,to explore appropriate iodine level in drinking water,and to provide a scientific basis for adjustment of intervention strategies.MethodsAccording to the Monitoring Program of the National Iodine Deficiency Disorders (Trial),qualified iodized salt consumption rate,drinking water iodine content and urinary iodine levels of women of childbearing age were determined in iodine deficiency areas from 2003 to 2010.Salt iodine was detected by direct titrimetry,urinary iodine by As-Ce catalytic spectrophotometric assay and iodine in drinking water by cerous sulfate catalytic spectrophotometric method.Results Intake rate of qualified iodized salt was up to 90％ and above from 2003 to 2010,median water iodine was 13.65 μg/L in the 10 counties(cities,districts),of which less than 100 μg/L accounted for 79.82％(4560/5713 ) and ＞ 150 μg/L accounted for 12.73％(727/5713).With the increase of water iodine(0 ～ ＜ 10,10 ～ ＜ 50,50 ～ ＜ 100,100 ～ ＜ 150,150 ～ ＜ 300 and ≥300 μg/L),urinary iodine levels of women of childbearing age increased successively(median 156.56,175.81,267.04,349.00,524.22,583.20 μg/L,respectively,x2 =121.20,P ＜ 0.05),while the ratio of urinary iodine ＜ 100 μg/L was significantly lower.The ratio of urinary iodine between 100 and 300 μg/L was decreased gradually,but the ratio of great than 300 μg/L was gradually increased.ConclusionsIodine deficiency areas in Jinan have reached the standard of elimination of iodine deficiency disorders.We should insist to carry out our measures to suit local conditions,classified guidances and scientific principals of iodine supplementation.

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.

Objective To explore the value of quantitative measurement of carotid intima-media thickness and elasticity for evaluating the degree of coronary heart disease by radio frequency ultrasonography. Methods From February 2011 to June 2012, a total of 142 subjects in cardiovascular internal medicine of the fourth military medical university Tangdu hospital with suspected CAD were enrolled in this study and were divided into non CAD group (n=35), atherosclerosis group in which coronary stenosis rate was less than 50%and no hemodynamic changes were detected (n=33), single artery involved group in which coronary stenosis rate was more than 50% (n=36) and multi-artery involved group in which coronary stenosis rate was more than 50%(n=38) based on the results of the coronary angiography (CAG). Measure the left common carotid artery intima-media thickness (IMT) and blood vessel elasticity index including the left common carotid artery pulse wave velocity (PWV) and stiffness index (β). Receiver operating characteristic (ROC) curves were used to calculate and compare the degrees of coronary heart disease, area under the curve of the left carotid artery elasticity parameters, cut-off value,sensitivity, speciifcity and Youden's index. Results LIMT, LPWV and Lβhad statistical signiifcance differences among four groups (F=3.621, 4.769 and 4.756, all P<0.05). The maximum values of parameter area under ROC curve were all observed in multi-artery involved groups and were 0.759 (LIMT), 0.770 (LPWV) and 0.764 (Lβ). The maximum value of Youden's index of the left common carotid artery intima-media thickness was observed in the coronary atherosclerosis group and was 0.513. The maximum value of Youden's index of the left common carotid artery pulse wave velocity and stiffnessβwere both observed in the multi-artery involved group and were 0.524 and 0.469. For diagnosing multivessel lesions, the sensitivities of LIMT, LPWV and Lβwere 71.0%, 77.4%and 71.0%, and the speciifcities were 73.4%, 74.7%and 75.9%. Conclusions The carotid elastic parameters have better predictive value for multivessel lesions. LPWV and Lβhave higher predictive value for coronary arterial disease than LIMT.
