| 1 | Simple method of measuring ocular rotation in supine position during small incision lenticule extraction显示文摘AIM:To introduce a novel measurement method of static cyclotorsion in small incision lenticule extraction(SMILE)and to investigate the effect of preoperative parameters on cyclotorsion and the effect of cyclotorsion on postoperative outcomes.METHODS:The medical records of 242 patients and 484 eyes who under went SMILE surger y were retrospectively reviewed.Preoperative intraocular pressure,refractive error,and corneal thickness were investigated.Refractive values and visual acuity were measured at 1d,1,3,and 6mo.Ocular cyclotorsion in the supine position was measured by calculating the location and angle of the incision site of the cornea in the anterior slit photograph taken after surgery.RESULTS:Of the total 484 eyes in 242 patients,preopera tive means phericale quivalent(SE)was-4.10±1.64 D,and the mean astigmatism was-0.82±0.74 D.Uncorrected distance visual acuity(UCVA)and SE improved significantly after the surgery.Moreover,219(45.2%)eyes had excyclotorsion,235(48.6%)eyes had incyclotorsion,and 30(6.2%)eyes had no torsion.The right eyes tended to be excyclotorted,and the left eyes tended to be incyclotorted(P<0.01).The mean cyclotorsion was 1.18°±3.69°,and the mean absolute value of cyclotorsion was 3.14°±2.26°.The range of cyclotorsion was 0.5°–11.4°.It was found that the smaller the preoperative sphere,the higher the amount of cyclotorsion(r=0.11,P=0.016).There was no significant association between the amount of cyclotorsion and preoperative astigmatism.There was no correlation between sex,preoperative corneal thickness,preoperative intraocular pressure,amount of cyclotorsion,and direction of cyclotorsion.The ratio of right eye excyclotorsion and left eye incyclotorsion on 1d was higher than that at 1,3,and 6mo(all P<0.01).There was no difference between the 1,3,and 6mo results in the right and left eyes(P=0.15,P=0.16,respectively).CONCLUSION:The newly devised ocular cyclotorsion measurement method can be used to evaluate ocular cyclotorsion after SMILE.Preoperative SE is associated with the amount of cyclotorsion,however,cyclotorsion doesn't have a significant effect on the results of SMILE surgery. | Jiho Song Hwanho Lee Moon Sun Jung Jae-hyung Kim | 2022 | International Journal of Ophthalmology(English edition)2022，15，8： | 1 |
| 4 | Plant-based,adjuvant-free,potent multivalent vaccines for avian influenza virus via Lactococcus surface display显示文摘Influenza epidemics frequently and unpredictably break out all over the world,and seriously affect the breeding industry and human activity.Inactivated and live attenuated viruses have been used as protective vaccines but exhibit high risks for biosafety.Subunit vaccines enjoy high biosafety and specificity but have a few weak points compared to inactivated virus or live attenuated virus vaccines,especially in low immunogenicity.In this study,we developed a new subunit vaccine platform for a potent,adjuvant-free,and multivalent vaccination.The ectodomains of hemagglutinins(HAs)of influenza viruses were expressed in plants as trimers(tHAs)to mimic their native forms.tHAs in plant extracts were directly used without purification for binding to inactivated Lactococcus(iLact)to produce iLact-tHAs,an antigen-carrying bacteria-like particle(BLP).tHAs BLP showed strong immune responses in mice and chickens without adjuvants.Moreover,simultaneous injection of two different antigens by two different formulas,t^(HAH5N6+H9N2) BLP or a combination of t^(HAH5N6) BLP and t^(HAH9N2) BLP,led to strong immune responses to both antigens.Based on these results,we propose combinations of plant-based antigen production and BLP-based delivery as a highly potent and cost-effective platform for multivalent vaccination for subunit vaccines. | Shi-Jian Song Gyeong-Im Shin Jinyong Noh Jiho Lee Deok-Hwan Kim Gyeongryul Ryu Gyeongik Ahn Hyungmin Jeon Hai-Ping Diao Youngmin Park Min Gab Kim Woe-Yeon Kim Young-Jin Kim Eun-Ju Sohn Chang Seon Song Inhwan Hwang | 2021 | Journal of Integrative Plant Biology2021，63，8： | 0 |
