Effect of Chitosan-assisted Combination of Laparoscope and Hysteroscope on the Levels of IFN-γ and ICAM-1 in Treatment of Infertility Caused by Obstruction of Fallopian Tubes.

This experiment was carried out to investigate the effect of combined treatment of tubal obstruction infertility with deacetylated chitosan and two microscopes on the levels of IFN-γ and ICAM-1. In this study, 100 infertile patients with fallopian tube obstruction who were treated in Jiangbei District Hospital of traditional Chinese medicine from January to August 2019 were divided into two groups according to the alternating grouping method, group A (50 cases) received combined surgery, and Group B (50 cases) received combined surgery and chitosan. The curative effect and postoperative pelvic adhesion of the two groups were analyzed, and the levels of IFN-γ, ICAM-1 and IL6(IL-6), laminin (LN), Transforming growth factor beta 1(TGF-ß1) and fibronectin (FN) were observed before and after treatment. Results showed that the total effective rate of Group B was higher than that of Group A (92. 00% vs 76. 00%). The incidence of pelvic adhesion was lower in Group A (4. 00% vs 16. 00%) (P < 0.05). The levels of IFN-γ, ICAM-1, IL-6, LN, FN and TGF-ß1 in Group B were significantly lower than those in group A (P < 0.05). In conclusion, the treatment of tubal obstruction infertility with combined deacetylated chitosan and biendoscopy is effective, which can reduce the levels of IFN-γ and ICAM-1, improve the expression of adhesion-related factors and reduce the occurrence of pelvic adhesion.

Efficacy of 20G or 25G three-channel vitrectomy for idiopathic macular epiretinal membrane / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To explore the curative effect of 20G and 25G three-channel pars plana vitrectomy in the treatment of idiopathic macular epiretinal membrane,and to provide a theoretical basis for the minimally invasive treatment of idiopathic macular epiretinal membrane.METHODS:Medical records were retrospectively analyzed to explore curative effect.From January 2014 to December 2016,60 patients (60 eyes) with idiopathic macular pucker in our hospital for eye treatment were selected.They were grouped according to different operation way,in 28 patients (28 eyes) using three-channel 20G pars plana vitrectomy as the control group,32 patients (32 eyes) with 25G no-suture conjunctival vitrectomy as observation group.Two groups of patients were evaluated at 3mo after treatment for visual acuity,OCT examination,comfort,and we recorded the operation time,complications and recurrence.RESULTS:The operating time of observation group was 18-25min,average 20±2.15min,the control group was 22-35min,28 ± 2.07min on average,the difference was statistically significant (P＜0.05).At the time of the last follow-up,visual acuity of two groups improved compared with preoperative,without vision decrease.In observation group vision improved in 69％,significantly higher than that of control group (50％),difference was statistically significant (x2 =7.287,P＜ 0.05).Preoperative intraocular pressure of two groups was not significantly different.intraocular pressure of two group at postoperative 1d reduced compared with preoperative (Ftime =31.34,P＜0.01;Fgr.up =17.43,P＜0.01).There was no statistically significant difference at 7d and 1mo compared with preoperative (P＞0.05).Preoperative OCT on macular thickness of the two groups had no statistically significant difference.At 7d,1 and 3mo after treatment,epiretinal membranes disappeared in all patients,and the macular thickness reduced,the macular edema relieved (P＜ 0.05).At postoperative 3mo,two groups of patients were found no recurrence of epiretinal membranes.At 7d,1 and 3mo after treatment,differences between the two groups on macular thickness had no statistical significance.At postoperative 1d,in the control group there were foreign body sensation,swelling,and tears,pain and discomfort,20 patients with eye conjunctival congestion,edema,conjunctival suture to cause discomfort,the symptoms relieved after treatment.In observation group,12 patients with mild conjunctival congestion and edema,dotted hemorrhage at the wound in 4 eyes,5 eyes appeared lower intraocular pressure (6-8mmHg).without special treatment,Postoperative bleeding and edema stopped at 7d,intraocular pressure returned to normal.Patients of observation group did not have foreign body sensation,swelling and discomfort symptoms.At the time of the last follow-up,in the two groups,no iatrogenic retinal detachment,cataract,endophthalmitis and other serious complications occurred.CONCLUSION:The 20G of three-channel pars plana vitrectomy and 25G the no-suture conjunctival vitrectomy are equal for idiopathic macular epiretinal membrane,25G vitrectomy operation time is short with better patient comfort.
