ABSTRACT
Objective:To investigate the efficiency and safety of pneumatic retinopexy for rhegmatogenous retinal detachment (RRD).Methods:A prospective case series study. From January 2020 to December 2021, 27 eyes of 27 RRD patients in Joint Shantou International Eye Center were included. Among them, there were 10 males and 17 females; the mean age was 36.0±11.8 years old. There was recurrent retinal detachment in 4 eyes. Best corrected visual acuity (BCVA) and optical coherence tomography were performed. According to whether the retina was successfully reattached after a single intravitreal injection, the patients were divided into a single operation group and a second operation group. All eyes underwent pneumatic retinopexy, the patients received intravitreal injection of 0.3-0.5 ml 100% C 3F 8. On the next day, laser photocoagulation was performed around the retinal breaks. The mean follow-up time was 15.0±6.0 months. Outcome measures included single operation success rate, the BCVA at the last follow up and complications. The age, gender, extent of retinal detachment, number of retinal breaks, and preoperative and postoperative BCVA of patients in the single operation group and the second operation group were compared using Mann-Whiteney test or Fisher's exact test. Results:Twenty of the 27 eyes (74.1%, 20/27) had retinal reattachment after single operation, 7 of the 27 eyes (25.9%, 7/27) had retinal reattachment after the second operation. Among the 7 eyes, retinal detachment recurrence after operation, retinal detachment recurrence after tear opening, and retinal detachment recurrence with new tears occurred in 1, 4, and 2 eyes, respectively; retinas were all reattached after scleral buckling or vitrectomy. The BCVA was stable and improved in 14 and 13 eyes, respectively. Compared with the single operation group, the retinal detachment in the second operation group was wider and the BCVA before operation was worse, the differences were statistically significant ( Z=-2.842,-2.233; P<0.05). Transient intraocular pressure elevation occurred in 5 eyes; no complications such as infectious endophthalmitis, intraocular hemorrhage and lens damage occurred. Conclusion:Pneumatic retinopexy is safe and effective in the treatment of RRD.
ABSTRACT
Objective To evaluate the effectiveness and safety of modified largeincision manual cataract extraction combined with intraocular lens (IOL) implantation for high myopia with cataract.Methods Twenty-eight patients (32 eyes) of high myopia with cataract underwent modified large-incision manual cataract extraction combined with IOL implantation.The nuclear hardness of 20 eyes were in degree Ⅲ,11 eyes were in degree ⅣV,1 eye was in degree V.The follow-up time was form 2 months to 12 months,the visual acuity,refraction and complications were observed and analyzed,Resuits In 32 eyes,the postoperative best corrected visual acuity (BCVA) was better than pre-operation in 28 eyes,4 eyes had no any improvement,in which the server high myopic fundus disease was found.The preoperative and postoperative BCVA were (1.43 ± 0.73) IogMAR and (0.84 ± 0.71) logMAR,and the sphere equivalent were (-15.33 ± 5.03) D and (-1.86 ± 1.41) D,the differences were statistically significant (all P ＜ 0.05).The intraoperative partial suspensory ligament occurred in 1 eye,iris hemorrhage appeared in 1 eye when extracting the lens nucleus;The postoperative mild corneal edema was seen in 11 eyes,hyphema in 1 eye,temporary high IOP in 1 eye,uveitis in 3 eyes,which disappeared within 1 week after treatment.IOL were implanted into capsular bag except 1 eye for partly broken ciliary zonule.There was no IOL dislocation within the follow-up.Conclusion Modified large-incision manual cataract extraction combined with IOL implantation is safe and effective for high myopia with cataract.
ABSTRACT
Objective: To observe the effect of tripterygium polyglycosid(TP,雷公藤) on airway inflammation and remodeling in rats with asthma.Methods: Forty rats were randomly divided evenly into negative control group,positive control group,normal dose TP group(TPⅠ group) and small dose TP group(TPⅡgroup).The experimental model was induced by ovalbumin sensitization.Number of cells in bronchoalveolar lavage fluid(BALF) was observed by immunocytochemical staining.The expressions of nuclear factor-?B(NF-?B),matrix metalloproteinases-9(MMP-9) and tissue of inhibitor of metalloproteinases-1(TIMP-1) were detected by immunohistochemistry method.Results: Compared with the negative control group,the counts of lymphocyte,neutrophilic leukocyte,macrophage and eosinocyte in BALF were elevated significantly,positive cell percentages of NF-?B, MMP-9 and TIMP-1 in lung tissues increased greatly in positive control group,the differences being significant(all P
