ABSTRACT
AIM: To assess the astigmatism-correcting efficiency and clinical effects of cataract phacoemulsification combined with bifocal Toric intraocular lens(IOL)implantation. METHODS: Retrospective analysis. The clinical data of 46 patients(46 eyes)with cataract complicated with regular corneal astigmatism by the treatment of cataract phacoemulsification and bifocal Toric IOL implantation in our hospital from August 2020 to September 2021 were included. The patients were followed up for 3mo after operation, and the changes of uncorrected distant visual acuity(UDVA), uncorrected near visual acuity(UNVA), best corrected distant visual acuity(BCDVA), best corrected near visual acuity(BCNVA)and astigmatism before and 1, 3mo after operation were evaluated. The IOL axial rotation was measured and calculated, and a questionnaire was conducted to investigate the necessity of using glasses at different distances and overall satisfaction.RESULTS:After operation at 1 and 3mo, there were significant differences in UDVA, BCDVA, UNVA and BCNVA compared with those before operation(all P<0.001), and there was no significant difference in UDVA, BCDVA, UNVA and BCNVA at 1mo after operation and 3mo after operation(all P>0.0167). At 3mo after operation, 46 eyes(100%)of UDVA reached 0.20(LogMAR), 40 eyes(87.0%)of UNVA reached 0.20(LogMAR). Astigmatism vector analysis showed that the mean preoperative corneal astigmatism in this group was 1.88±0.70D, and the centroid value was 0.61D@177°±1.93D, the mean residual astigmatism at 3mo postoperatively was 0.33±0.30D, and the centroid value was 0.03D@34°±0.45D. After operation at 3mo, the axial rotation of IOL was 3°(0°, 5°). Only 5 eyes(11%)required some degree of refractive correction for near or intermediate distances. 83%(38 eyes)were satisfied or very satisfied with the surgical results CONCLUSION: The implantation of bifocal Toric IOL during cataract surgery could effectively correct corneal regular astigmatism, improve uncorrected distance and near vision, and had high patient satisfaction.
ABSTRACT
OBJECTIVE@#To analyse the clinical and laboratory characteristics of antinuclear antibody (ANA) positive rheumatoid arthritis (RA) patients.@*METHODS@#The clinical and laboratory data of 428 RA cases from Department of of Rheumatology and Immunology Peking University Third Hospital from Jan 2013 to Dec 2018 were collected and used to analyse characters between ANA positive group and ANA negative group. T test was used for the quantitative data in accordance with normal distribution. Wilcoxon rank sum test was used for the quantitative data of non normal distribution. The qualitative data were analyzed by chi square test. But while 1≤theoretical frequency < 5, chi square test of corrected four grid table was used. And Fisher exact probability method was used when theoretical frequency < 1.@*RESULTS@#The number of ANA positive group was 231 (54%). The female rate was obviously higher in ANA positive group (82.7% vs. 63.5%, χ2=20.355, P < 0.01). The rate of metatarsophalangeal joints (MTPJs) involvement was lower in ANA positive group (22.1%) than in ANA negative group (33.0) (χ2=6.414, P < 0.05). The incidence of secondary Sjögren's syndrome (sSS) was much higher in ANA positive group(19.5% vs. 4.1%, χ2=23.300, P < 0.01). The positivity of rheumatoid factor (RF), as well as the positivity of anti-cyclic citrullinated peptide(CCP) antibody was much higher in ANA positive group (77.1% vs. 53.8%, χ2=25.743, P < 0.01, 74.9% vs. 59.4%, χ2=11.694, P < 0.01, respectively). The levels of immunoglobulin G (IgG) and immunoglobulin M (IgM) of ANA positive group were higher [(15.1±5.1) g/L vs. (13.8±5.3) g/L, t=2.359, P < 0.05, 1.25 (0.92) g/L vs. 1.05 (0.65) g/L, Z=-3.449, P < 0.01, respectively]. But the levels of hemoglobin (Hb) and platelet (PLT) was lower in ANA positive group[(109.64±17.98) vs. (114.47±18.48) g/L, t=-2.734, P < 0.01; (266.4×109±104.6×109) vs. (295.9×109±100.1×109) /L, t=-2.970, P < 0.01, respectively].@*CONCLUSION@#The incidence of sSS was obviously higher in ANA positive group than in ANA negative group. Serum IgG of ANA positive group was higher, but Hb and PLT were lower.

To observe the effect of autologous stem cell transplantation in diabetic retinopathy. ●METHODS:Totally 58 cases (116 eyes) who underwent autologous stem cell transplantation were confirmed as no diabetic retinopathy (18 eyes), mild non-proliferative diabetic retinopathy (NPDR) (41 eyes), mid-level NPDR (51 eyes); severe NPDR (6 eyes) by ophthalmoscope directly or indirectly and fluorescence fundus angiography (FFA ). Follow - up was 6 - 12mo, the changes of retinopathy were observed. ●RESULTS: The total effective rate of vision and retinopathy was 84. 4%, 76. 7%. The results of severe NPDR was statistically worse than the other groups ( P ●CONCLUSlON: The stable blood glucose level and improved pancreatic function after autologous stem cell transplantation might be helpful in diabetic retinopathy, the long effects need to be researched further.
