Pentacam scheimpflug system utilize the principle of Scheimpflug to image the anterior eye segment.It equips with an automatically rotating Scheimpflug camera to perform a complete measurement of the anterior segment.A precise analysis of the corneal thickness,corneal topography,anterior chamber and crystalline lens are carried out during the operation.These data then provide the basis for a three-dimensional model of the complete anterior segment.The Pentacam scheimpflug system offers a wide range of functions in refractive surgery,keratoconus analysis,glaucoma screening and phacoemulsification.The newest progression in the application of the Pentacam in anterior ocular segment photography were reviewed.

Objective To investigate the correlation between glucose variability and coronary stenosis in type 2 diabetes mellitus (T2DM) combined with coronary heart disease (CHD) patients.Methods Eighty patients with T2DM who had undergone coronary angiography were selected.According to the result of coronary angiography,the patients were divided into 2 groups:48 T2DM combined with CHD patients as CHD group,and 32 T2DM combined without CHD patients as control group.All patients underwent continuous glucose monitoring (CGM) for 72 h,and the mean blood glucose (MBG),standard deviation of blood glucose (SDBG),daily mean amplitude of glycemic excursion (MAGE),absolute means of daily differences (MODD),largest amplitude of blood glucose excursion (LAGE) and mean postprandial glucose excursion (MPPGE) were computed.The risk factor of coronary stenosis (using Gensini score) was analyzed.Results The LAGE,SDBG,MAGE,MPPGE,MODD in CHD group were significantly higher than those in control group:(11.4 ± 3.6) mmol/L vs.(8.2 ± 1.9) mmol/L,(3.4 ± 1.4) mmol/L vs.(1.9 ± 0.6) mmol/L,(7.1 ± 2.7) mmol/L vs.(4.8 ± 1.4) mmol/L,(6.6 ± 1.8) mmol/L vs.(4.6 ± 1.5) mmol/L,(3.3 ± 1.2) mmol/L vs.(2.5 ± 0.9) mmol/L,and there were statistical differences (P ＜ 0.05).There was no statistical difference in MBG between CHD group and control group:(10.2 ± 2.8) mmol/L vs.(9.3 ± 2.2) mmol/L,P ＞ 0.05.The Pearson correlation analysis result showed that the MPPGE,MODD and LAGE had positive correlation with Gensini score (r =0.509,0.357 and 0.338;P ＜ 0.05);and the LVEF had negative correlation with Gensini score (r =-0.372,P ＜ 0.05).Conclusions Glucose variability in patients with T2DM combined with CHD is markedly enhanced.MPPGE,MODD and IAGE are positively correlated with the severity of coronary stenosis.

Epidemic surveillance is critical to infectious disease prevention and control .This article describes the evolution and current situation of epidemic surveillance in PLA , systematically analyzes major problems with epidemic surveillance , including incomplete surveillance , simplistic surveillance methods , outdated surveillance technology , inefficient disease diagnosis , poor epidemic prediction , and administrative interference in epidemic reporting .Ways to enhance epidemic surveillance are described here , such as carrying out comprehensive surveillance , and expanding the contents of surveillance , strengthening active surveillance , optimizing surveillance methods , speeding up informatization construction , innovating surveillance technology ,improving disease diagnosis technology , enhancing the ability of epidemic recognition,carrying out the prediction research ,improving the ability of early warning ,perfecting the system construction , and strengthening the awareness of infectious disease reporting .
