Objective:To evaluate the feasibility of measurement and characteristics of intraocular lens (IOL) tilt using the swept-source optical coherence tomography (SS-OCT) biometer (IOLMaster 700) and to explore its potentially relevant parameters.Methods:A cross-sectional study was conducted.Two hundred and forty-two eyes (119 right eyes, 123 left eyes) of 185 patients after phacoemulsification and IOL implantation were included in Beijing Tongren Hospital from July to September 2018.The IOL position, angle κ, angle α, corneal curvature, anterior chamber depth (ACD), pupil diameter (PD), and axial length (AL) were obtained by IOLMaster 700, and the IOL tilt direction and magnitude were calculated.The within-subject standard deviation and intraclass correlation coefficient were used to evaluate the repeatability of three IOL tilt measurements.Binocular symmetry of IOL tilt and the correlation between IOL tilt and different influencing factors were evaluated by Pearson linear correlation analysis or Spearman rank correlation analysis.Influencing factors for IOL tilt were assessed by multiple linear regression analysis.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.TRECKY2018-049). Patients were informed of the purpose and methods of this study and signed the written informed consent.Results:The repeatability of IOL tilt measurements was excellent with a within-subject standard deviation of 5.16° for IOL tilt direction and 0.13° for IOL tilt magnitude.IOL tilt was mirror symmetric in both eyes.The IOL tilt direction in right eyes ranged from -89.60° to 87.53° with a mean of (18.85±29.65)°, and the tilt magnitude ranged from 1.32° to 7.05° with a mean of (4.16±1.26)°.The IOL tilt direction in left eyes ranged from -84.30° to 89.44° with a mean of (21.17±32.38)°, and the tilt magnitude ranged from 0.58° to 7.40° with a mean of (3.80±1.31)°.There were moderate and weak positive correlations of IOL tilt direction and tilt magnitude between both eyes ( r=0.473, P<0.001; r=0.335, P=0.011). IOL tilt magnitude was weakly positively correlated with angle α and IOL diopter ( rs=0.272, P=0.003; r=0.285, P=0.002), and was weakly negatively correlated with ACD, PD and AL ( r=-0.303, P=0.001; r=-0.233, P=0.011; rs=-0.331, P<0.001). In backward stepwise regression analysis, the regression equation of IOL tilt magnitude, angle α, ACD, PD, AL and IOL diopter in multiple linear regression analysis was as follows: IOL tilt magnitude=10.503+ 1.456×angle α-0.532×ACD-0.196×AL ( R2=0.400; F=8.588, P<0.001). Conclusions:The SS-OCT biometer can be an effective method to assess IOL tilt.IOL tilt is mirror symmetric between the right eyes and left eyes.

Objective:To discuss the characteristics of ultrasound diagnosis of optic disc capillary hemangioma.Methods:The study analyzed retrospectively 7 cases of optic disc capillary hemangioma diagnosed in the Beijing Tongren Hospital from 2015 to 2018. The size, morphology, internal echo, and secondary changes of the lesion were analyzed during ultrasound examination.Color Doppler flow imaging was used to check the blood flow in the lesion.Results:Pre-optic disc occupying lesions could be detected in the ultrasound images of the 7 cases. Lesion size: average base diameters (5.39±1.90)mm×(4.79±1.28)mm, average height (3.61±1.37)mm. Lesion morphology: 5 cases were round, and 2 cases were irregular. Echo within the lesion: 3 cases had medium echo inside the lesion, and 4 cases had high echo inside the lesion. Internal echo characteristics: 5 cases had uniform echo, and 2 cases had uneven echo. Secondary changes: 6 cases had secondary retinal detachment and vitreous opacity, and 1 cases was accompanied by retinal hemangioma in other parts. In all cases, blood flow signals could be detected inside the space-occupying lesions, which were in the form of branches, stripes or spots, and the blood flow spectrum showed a parallel spectrum of arteries and veins.Conclusions:Ultrasound examination of optic disc capillary hemangioma has certain characteristics, which can provide a valuable follow-up basis for clinical diagnosis.

Objective To observe the application value with color Doppler flow imaging (CDFI) in the detection ofmacular diseases in senile cataract.Methods A cross-sectional descriptive study.From December 1 to December 30,2017,720 senile cataract patients (1380 eyes) diagnosed in Beijing Tongren Eye Center were included in this study.There were 330 males (629 eyes) and 390 females (751 eyes),with the mean age of 70.35 ± 19.05 years.There were 716 right eyes and 664 left eyes,with the visual acuity 0.05-0.8.The fundus of all the patients can be observed.All patients were examined by OCT using Cirrus HD-Model 5000 produced by German Carl Zeiss company and CDFI using MyLab90 color Doppler ultrasound system produced by ESAOTE S.P.A.Comparing the detection rate of macular lesions between the two methods by using X2 test.Using statistical methods to evaluate diagnostic tests,a crosstabulation was made to compare the consistency of frequency-domain OCT and CDFI in the diagnosis of macular lesions.Logistic regression analysis of correlation between detection of CDFI macular lesions and central foveal thickness (CFT),average thickness (AT),with or without macular anterior membrane,retinal folds,retinal cystoid edema,hard exudation,macular hole or lamellar macular hole,superficial detachment of neuroepithelium,detachment of pigment epithelium,vitreous macular traction.Results Two hundreds and thirty-nine eyes (17.3％) showed macular disease by OCT,and 161 eyes (11.7％) showed the abnormal echo in the macular region by CDFI.The detection rate of the macular disease between two methods were statistically significant (χ2=851.661,P＜ 0.001),however,the consistency was well (r=0.766,P=0.000).Logistic analysis showed that the detection rate of macular lesions was related to retinal folds,cysts in retina and CFT (r=1.396,1.041,0.12;P＜0.01).Conclusion CDFI can effectively detect macular lesions that affect the visual prognosis of senile cataract patients.

Objective:To compare the agreement of biometric parameters measured by a new swept-source optical coherence tomography IOLMaster 700 and a new Scheimpflug imaging combined with partial coherence interferometry biometer Pentacam AXL in cataractous eyes.Methods:A cross-sectional study was performed.A total of 146 eyes from 76 cataract patients were enrolled in Beijing Tongren Eye Center from 2 to 11 in January 2018, including 69 eyes in 36 males and 77 eyes in 40 females, the age ranged from 35 to 88 years, the mean age was (64.52±11.36) years.Axial length (AL), mean keratometry (Km), anterior chamber depth (ACD), central corneal thickness (CCT) and white-to-white (WTW) were measured with IOLMaster 700 and Pentacam AXL, respectively.The differences and correlations of the biometry parameters between the two devices were assessed.Bland-Altman method was used to evaluate the agreement of these parameters between the two devices and the 95% limits of agreement was calculated.This study adhered to the tenets of the Declaration of Helsinki and was approved by an Ethics Committee of Beijing Tongren Hospital (TRECKY2018-049).Results:The mean values of the AL measured by IOLMaster 700 and Pentacam AXL were (24.03±1.72)mm and (23.98±1.73)mm, Km were (44.04±1.71)D and (43.88±1.72)D, ACD were (3.24±0.47)mm and (3.28±0.47)mm, WTW were (11.82±0.51)mm and (11.49±0.49)mm, respectively.Compared with the values in Pentacam AXL, the AL, Km and WTW were larger while ACD was smaller in IOLMaster 700 with significant differences ( t=18.06, 8.94, 23.83, -15.36, all at P<0.01). The mean CCT values from the IOLMaster 700 and Pentacam AXL were (534.18±30.12)μm and (533.42±28.71)μm, respectively, with no significant difference ( t=1.04, P=0.30). The AL, Km, ACD, CCT and WTW from IOLMaster 700 were highly correlated with those from Pentacam AXL ( r=0.999, 0.992, 0.998, 0.956, 0.942; all at P<0.01). The Bland Altman analysis showed that the 95% limits of agreement of AL, Km, ACD, CCT and WTW were-0.02-0.11 mm, -0.27-0.59 D, -0.10-0.02 mm, -16.5-18.1 μm and 0.00-0.67 mm. Conclusions:IOLMaster 700 and Pentacam AXL have good agreements and narrow 95% limits of agreement in the measurements of AL, ACD, CCT, which can be clinically interchangeable.The 95% limits of agreement of WTW and Km are out of the clinically acceptable range, so the WTW and Km measured by the two devices are not interchangeable.

Objective To investigate the correlation between quantitative parameters derived from iodine overlay images and the monochromatic images of dual‐energy CT and the differentiation degree of laryngeal and hypopharyngeal squamous cell carcinoma(LHSCC). Methods Retrospective analysis of clinical and imaging data of eighty patients with different differentiation degree of LHSCC who underwent dual‐energy CT enhanced scan in the arterial and venous phase from March 2016 to January 2017 (20, 42 and 18 patients with well, moderately and poorly differentiation, respectively) was performed.Among them, twenty‐eight cases were stage T1, twenty‐four cases were stage T2, twenty cases were stage T3 and eight cases were stage T4. All patients were not treated with radiotherapy and chemotherapy before operation. Iodine overlay images and the monochromatic images of arterial and venous phases were acquired from Syngo MultiModality Workplace dual‐energy post‐processing software of Siemens, respectively. The mean iodine concentration (IC), standardized iodine concentration (SIC), and the slope of spectral curve(λ) of different differentiation degrees of LHSCC were calculated and compared. The correlation between quantitative parameters of LHSCC and its differentiation degree was performed by Spearman rank sum test. One‐way analysis of variance was used to compare the quantitative parameters of different differentiation degree of LHSCC. Receiver operating characteristic (ROC) curve was used for analyzing diagnostic efficiency. Results The IC, SIC, and λ in the arterial phase, and IC in the venous phase correlated positively with differentiation degree in LHSCC (r=0.258, 0.350, 0.262 and 0.275, respectively; P<0.05) in this group. The IC, SIC, and λ of poorly differentiated LHSCC in the arterial phase [(3.13 ± 0.54) mg/ml, (0.38±0.10), (5.40±0.92)] were higher than those of well differentiated LHSCC [(2.38±1.02) mg/ml, (0.25± 0.09) and (4.19 ± 1.18); t=2.73, 3.36 and 2.75 respectively; P<0.05] and moderately differentiated LHSCC [(2.56±0.85) mg/ml, (0.28±0.16) and (4.56±1.41); t=2.38, 3.06 and 2.21, P<0.05]. IC of poorly differentiated LHSCC in the venous phase [(2.59 ± 0.62) mg/ml] was significantly higher than that of well differentiated LHSCC [(1.96±0.56) mg/ml,t=2.45,P<0.05] and moderately differentiated [(2.02±0.93) mg/ml,t=2.56,P<0.05] LHSCC. There was no significant difference in the SIC and λ between different differentiation degrees of LHSCC (P>0.05) in the venous phase. The standardized iodine concentration in the arterial phase was the best in distinguishing poorly and moderately differentiated LHSCC, and poorly and well differentiated LHSCC with the area under the receiver operating curve 0.77 and 0.81, respectively, the sensitivity 88.2% and 70.0%, respectively, and the specificity 69.0% and 70.0%, respectively. Conclusions Quantitative parameters derived from dual‐energy CT might be useful in the evaluation of different differentiated degrees of LHSCC. In addition, the standardized iodine concentration of LHSCC in the arterial phase was the best in the estimation of different differentiated degrees of LHSCC.

Objective To investigate the effect of ear massage on blood pressure and sleep quality of hypertensive patients . Methods Two hundred and ninety-eight elderly hypertensive patients were nursed on the basis of conventional therapy. One hundred and forty-eight patients randomly selected were set as the experiment group, where they were given intervention of ear massage. Another one hundred and fifty patients were set as the control group and treated with conventional interventions. The two groups were compared in terms of blood pressure (systolic and diastolic blood pressure) after nursing interventions and the sleep quality (by Pittsburgh sleep quality index, PSQI). Result After intervention, the diastolic and systolic blood pressure values in the experiment group were both significantly decreased than before intervention (P<0.05) and the quality of sleep was significantly lower than that before intervention (P<0.05). Conclusion Ear massage can be effective in regulating blood pressure in elderly hypertensive patients and improving their quality of sleep.

Objective To investigate the effects of nursing intervention combined with preventive medication on adverse reactions during fundus fluorescence angiography ( FFA ) . Methods From January 2012 to 2014, a total of 2 840 patients, who underwent FFA at the Second Hospital of Hebei Medical University for the first time, were randomly assigned to nursing intervention group, preventive medication group, combination group and control group, then we compared the type and ratio of adverse reactions to figure out the most efficient measurement. Results The ratio of systematic anaphylaxis reaction and adverse reaction of digestive system and adverse reactions of nervous system were 1. 5%,1. 4% and 1. 3% in the combination group, that both were lower than these in nursing intervention group, preventive medication group and control group (χ2 =82. 747, 8.128, 7.626,respectively;P <0. 05). Conclusions The combination of nursing intervention and preventive medication can efficiently minimize the occurrence of adverse reactions during FFA.
