RESUMEN
Objective:To evaluate the value of shear wave elastography (SWE) and salivary gland ultrasound scoring(SGUS) system in the diagnosis of salivary glands lesions in patients with Sj?gren′s syndrome(SS) and to compare the diagnostic efficiency of the two methods.Methods:From June 2019 to November 2020, Fifty-eight patients with suspected SS were selected from the Affiliated Changzhou No.2 People′s Hospital of Nanjing Medical University. According to the 2002 American-European Consensus Group classification standard, the enrolled patients were divided into two groups: SS group (47 cases) and non-SS group(11 cases). According to symptom duration, SS group was divided into the ≤5 years group (29 cases) and the >5 years group (18 cases). Meanwhile, 40 healthy volunteers were enrolled in this study as normal control group. The diagnostic value of salivary gland ultrasound scoring system and Young′s modulus in SS were analyzed.Results:The differences in Young′s modulus of parotid gland and submandibular gland between SS group and non-SS group (or control group) were statistically significant (all P<0.05). The ultrasound score of SS group was significantly higher than that of non-SS group and control group (all P<0.05). SGUS and Young′s modulus were not significantly different between different course groups (all P>0.05). The areas under ROC curve of the mean Young′s value in parotid and submandibular gland and the SGUS were 0.801, 0.829 and 0.676, respectively. The comparison of the area under the curve between the Young′s modulus of the parotid and submandibular glands and the ultrasound score was statistically significant (all P<0.05). Conclusions:SWE and Ultrasonography scoring system have certain value in the diagnosis of salivary gland lesions in SS, and can provide important reference information for clinical diagnosis from different perspectives. The diagnostic efficiency of SWE for salivary glands lesions in patients with SS is better than that of SGUS scoring system.
RESUMEN
Objective To evaluate the macular visual function of patients with myopic choroidal neovascularization (MCNV) before and after intravitreal injection of conbercept.Methods A prospective,uncontrolled and non-randomized study.From April 2017 to April 2018,21 eyes of 21 patients diagnosed as MCNV in Shanxi Eye Hospital and treated with intravitreal injection of conbercept were included in this study.There were 9 males (9 eyes,42.86％) and 12 females (12 eyes,57.14％),with the mean age of 35.1 ± 13.2 years.The mean diopter was-11.30 ± 2.35 D and the mean axial length was 28.93 ± 5.68 mm.All patients were treated with intravitreal injection of conbercept 0.05 ml (1+PRN).Regular follow-up was performed before and after treatment,and BCVA and MAIA micro-field examination were performed at each follow-up.BCVA,macular integrity index (MI),mean sensitivity (MS) and fixation status changes before and after treatment were comparatively analyzed.The fixation status was divided into three types:stable fixation,relatively unstable fixation,and unstable fixation.The paired-sample t-test was used to compare BCVA,MI and MS before and after treatment.The x2 test was used to compare the fixation status before and after treatment.Results During the observation period,the average number of injections was 3.5.The logMAR BCVA of the eyes before treatment and at 1,3,and 6 months after treatment were 0.87±0.32,0.68±0.23,0.52±0.17,and 0.61 ±0.57,respectively;MI were 89.38 ± 21.34,88.87 ± 17.91,70.59 ± 30.02,and 86.76 ± 15.09,respectively;MS were 15.32 ± 7.19,21.35 ± 8.89,23.98 ± 11.12,22.32 ± 9.04 dB,respectively.Compared with before treatment,BCVA (t=15.32,18.65,17.38;P＜0.01) and MS (t=4.08,3.50,4.26;P＜0.01) were significantly increased in the eyes 1,3,and 6 months after treatment.There was no significant difference in the MI of the eyes before treatment and at 1,3,and 6 months after treatment (t=0.60,2.42,2.58;P＞0.05).Before treatment and at 1,3,and 6 months after treatment,the proportion of stable fixation were 28.57％,38.10％,38.10％,33.33％;the proportion of relatively unstable fixation were 47.62％,47.62％,52.38％,57.14％ and the proportion of unstable fixation were 23.81％,14.28％,9.52％,9.52％,respectively.The proportion of stable fixation and relatively unstable fixation at 1,3 and 6 months after treatment were higher than that before treatment,but the difference was not statistically significant (x2=1.82,1.24,1.69;P＞0.05).Conclusion BCVA and MS are significantly increased in patients with MCNV after intravitreal injection of conbercept.
RESUMEN
Objective@#To analyze the microvessel density (MVD) and lymph node metastasis in the papillary thyroid carcinoma (PTC) with punctate or sheet calcification.@*Methods@#Fifty PTC patients in the Affiliated Hospital of Yangzhou University from May 2015 to October 2017 were retrospectively enrolled in this study. All of the 50 PTC patients were divided into punctate calcification group (38 cases) and sheet calcification group (12 cases) according to the different features of pathological calcification in microscope examination. For the two groups, the central and peripheral zone MVD and the lymph node metastasis of each PTC nodule were compared.@*Results@#For PTC nodules of punctate calcification group, the mean central and peripheral zone MVD were (51±7)/HP and (64±8)/HP, respectively. For those of sheet calcification group, which were (35±5)/HP and (49±6)/HP, respectively. The mean MVD in both central and peripheral zone of PTC nodules of punctate calcification group were significantly higher than those of the sheet calcification group (t values were 10.183 and 12.406, both P < 0.05). The neck Ⅵ area lymph node metastasis rates of the punctate and sheet calcification groups were 42.1% (16/38) and 8.3% (1/12), respectively. The lymph node metastasis rate of the punctate calcification group was significantly higher than that of the sheet calcification group (χ 2 = 4.635, P < 0.05).@*Conclusion@#PTC nodules with different type of pathological calcification may have different invasion and metastasis, and PTC with punctate calcification is more likely to undergo local metastasis than PTC with sheet calcification.
RESUMEN
Objective To evaluate the role of ultrasound biomicroscopy(UBM) as a method for assessing the zonules after eye blunt trauma,in order to help the selection of the surgical technique and improve the outcomes of traumatic cataract surgery.Methods Two hundred and seven eyes with eye blunt trauma were examed using UBM with a 50 MHz transducer.The degree and extent of the zonular defects were recorded.All patients also had the slit-lamp examination before the UBM.Results Examined using UBM,zonular defects were identified in 67 of 207 eyes(32.4%).Zonular abnormalities include broken zonules and stretched zonules.Forty-six eyes(68.7%) had broken zonules,15 eyes(22.4%) had stretched zonules,6 eyes(9.0%) had both broken and stretched zonules.The extent of broken zonules ranged from under one quadrant to 360?.Increased lenticular sphericity and ciliary body flattening were seen in the area of zonular defects on UBM.Examined using slit-lamp,35 of 207 eyes(16.9%) had phacodonesis and iridodonesis.Conclusions UBM is an effective method for identifying zonular defects in patients with anterior segment trauma.Diagnosing zonular defects preoperatively is of helpful in surgical planning and reduce complications.
