ObjectivesTo systematically review the efficacy and safety of the first generation EGFR-TKIs versus pemetrexed as second-line treatment for advanced non-small cell lung cancer (NSCLC).MethodsDatabases including PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM were searched to collect randomized controlled trials (RCTs) about the first generation EGFR-TKIs versus pemetrexed as second-line treatment for advanced NSCLC from inception to June 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 20 RCTs involving 2 242 patients were finally included. The results of meta-analysis showed that: the rate of progression free survival (PFS) in the EGFR-TKI group was superior to the pemetrexed group (HR=0.78, 95%CI 0.58 to 0.99, P<0.000 1) with significant difference. However, there was no significant difference between two groups in complete remission rate (RR=1.81, 95%CI 0.65 to 5.07,P=0.26), partial remission rate (RR=0.93, 95%CI 0.78 to 1.11, P=0.44), stable disease rate (RR=0.92, 95%CI 0.82 to 1.03, P=0.16), progression disease rate (RR=1.09, 95%CI 0.99 to 1.20, P=0.09), overall response rate (RR=0.97, 95%CI 0.72 to 1.30, P=0.84), disease control rate (RR=0.93, 95%CI 0.87 to 1.01, P=0.07) and overall survival rate (HR=0.89, 95%CI 0.74 to 1.04, P<0.572). The incidences of skin rash (RR=12.43, 95%CI 3.98 to 38.84,P<0.01) and diarrhea (RR=3.94, 95%CI 2.32 to 6.70,P<0.01) were significantly higher in the EGFR-TKI group, but the incidences of leukopenia (RR=0.19, 95%CI 0.09 to 0.41,P<0.01 ), anemia (RR=0.40, 95%CI 0.17 to 0.92,P=0.03), thrombocytopenia (RR=0.37, 95%CI 0.14 to 0.97, P=0.04), nausea and vomiting (RR=0.50, 95%CI 0.28 to 0.87, P=0.01), constipation (RR=0.30, 95%CI 0.14 to 0.64, P=0.002) were significant lower in the EGFR-TKI group than that of the pemetrexed group.ConclusionGefitinib shows some superiority to pemetrexed in second-line treatment for NSCLC, and it can be used as the second-line drug for advanced NSCLC. Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo comparatively analyze for the fundus characteristics of acquired immune deficiency syndrome (AIDS) with cytomegalovirus retinitis (CMVR) between first-visit and non-first-visit in ophthalmology.MethodsA retrospective study was performed for 22 patients (41 eyes) diagnosed as CMVR with AIDS by ophthalmology in the Affiliated Municipal Hospital of Xuzhou Medical University from July 2004 to September 2017. The patients were divided into two groups: one with the first-visit in ophthalmology (FVO) and the other with the first-visit in non-ophthalmology (FVNO). All patients underwent visual acuity, intraocular pressure, slit lamp microscope and indirect ophthalmoscope examinations. Thirty-nine eyes of 21 patients with clear refractive media were examined by color fundus photography, of which 5 patients were examined by FFA. Five patients examined by OCT and B-mode ultrasound. The CMVR were characterized as fulminant type or indolent type. All the 22 patients (41 eyes) except 2 patients (4 eyes) accepted highly active antiroviral therapy, and all patients were treated with ganciclovir intravenously. Nine patients (12 eyes) received intravitreal injection of ganciclovir, 7 patients (10 eyes) underwent vitrectomy because of retinal detachment, 6 patients (7 eyes) gave up surgery because of extensive retinal detachment, and the other 12 eyes did not undergo any eye surgery. All patients were followed for 6-58 months (average 23±39 months). The incidences and fundus characteristics of the patients with fulminant or indolent CMVR were compared and analyzed. Between the two groups, the difference of visual acuity and CD4+T cell count at the first vist and the last follow-up were analyzed by a t-test, and the macular involvement and spread of the two groups were compared by a chi-square test.ResultsFulminant CMVR showed dense yellow-white necrotic lesions along the great vessels with or without satellite lesions, while indolent CMVR showed sparse yellow-white granular lesions with a little bleeding. The concomitant signs included frost-like dendritic vascular sheath, retinal artery occlusion and optic disc edema. Fourteen eyes of 7 patients in FVO group were fulminant, including 2 patients (2 eyes) with retinal artery occlusion and 1 patient (two eyes) with optic disc edema. In FVNO group, there were 27 eyes of 15 patients, including 21 eyes of 13 cases identified as fulminant type and 6 eyes of 4 patients as indolent type. In the fulminant type, there were 4 patients (6 eyes) with frost-like dendritic vascular sheath, 10 patients (12 eyes) with retinal artery occlusion and 4 patients (4 eyes) with optic disc edema. There was no significant difference in initial visual acuity (t=－1.534, P=0.133), but there was a significant difference in visual acuity at the last follow-up (t=－3.420, P=0.001). There was no significant difference in CD4+ T cells between the two groups at the first visit (t=－0.902, P=0.378). The proportions of macular involvement and 3-4 quadrant involvement in FVO group were significantly higher than those in FVNO group (χ2=7.552, 7.865; P=0.006, 0.005).ConclusionFor AIDS patients with CMVR, the first-visit in ophthalmology showed more dense necrotic lesions involving macular and a wider range of lesions than the first-visit in non-ophthalmology.
ObjectiveTo observe and analyze the correlation between macular microvascular parameters and urinary albumin to creatinine ratio (UACR) in patients with type 2 diabetes mellitus (T2DM). MethodsA cross-sectional study. From October 2017 to April 2018, 100 eyes of 100 patients (T2DM) and 27 eyes of 27 healthy controls (the control group) were enrolled in Xuzhou First People’s Hospital. All subjects underwent anterior segment examination via slit-lamp biomicroscopy, dilated fundus examination, 7-field fundus photographs, OCT angiography (OCTA), the fasting glucose test, glycosylated hemoglobin (HbA1c), urinary albumin, urinary creatinine and UACR levels determination. Height and weight measurement were taken for calculating body mass index (BMI). Diabetic retinopathy was ruled out by fundoscopic examinations and 7-field fundus photographs in T2DM patients. According to the UACR, patients in the T2DM group were subdivided into A1 group (UACR< 30 mg/g), A2 group (UACR 30-300 mg/g), and A3 group (UACR>300 mg/g), with 38 cases and 38 eyes respectively , 40 cases with 40 eyes, 22 cases with 22 eyes. A 6 mm×6 mm scanning area centered on the macular fovea were scanned for right eye using a frequency domain OCTA instrument, which were divided into three concentric circles centered on the macular fovea by the software automatically. The foveal zone was defined as a circular area measuring 1 mm in diameter, the parafoveal zone was described as a middle circle area measuring 1-3 mm in diameter, and the perifoveal zone was an outer circle area measuring 3-6 mm in diameter. The vessel density of superficial capillary plexus (SCP) and deep capillary plexus (DCP), foveal avascular area (FAZ) and perimeter (PERIM), non-circularity index (AI) were measured. The correlation between the macular vessel density, FAZ and UACR was analyzed by Spearman correlation analysis. ResultsA1 group, A2 group, A3 group, and normal control group. The macular area SCP and DCP (F=13.722, 5.644), foveal area (F=4.607, 4.719), parafoveal area (H=23.142, F=2.904), the blood flow density of the area around the fovea (F=12.292, H=10.946), the difference was statistically significant (P＜0.05); with the increase of UACR, the blood flow density of each area of SCP and DCP showed a downward trend. The results of correlation analysis showed that the blood flow density of the whole SCP, parafoveal area, and surrounding area of T2DM patients was negatively correlated with UACR (r=－0.376, －0.240, －0.364, －0.347, P＜0.05). There were no correlation among fasting plasma glucose, HbAlc and UACR (r=0.179, 0.085, P＞0.05). There were no correlation among blood flow density in BMI, SCP foveal area, DCP and UACR (|r|＜0.3, P＞0.05). ConclusionThe whole, parafovea and perifovea vessel density values of SCP in T2DM eyes without DR are negatively correlated with UACR.
