Objective:To evaluate the efficacy and safety of limited pars plana vitrectomy(LPPV), pressure-controlled phacoemulsification(PCP), intraocular lens implantation(IOL), and posterior capsulotomy (PC) in treatment of nanophthalmic glaucoma eyes which intraocular pressure(IOP) were still out of control after peripheral iridectomy.Methods:All 24 patients(29 eyes) with nanophthalmic glaucoma whose IOP failed to be reduced after peripheral iridectomy and needed LPPV plus PCP plus IOL plus PC were recruited from July 2017 to April 2021. The age of these patients was(44.6±11.0) years old. Preoperative and postoperative IOP, best corrected visual acuity(BCVA), anterior chamber depth(ACD) and number of glaucoma medications were recorded by chart review and compared by using paired t-test or Wilcoxon signed rank-sum test. P<0.05 was considered as statistical significant. IOP could be controlled in normal range(≥5 mmHg and≤21 mmHg), without both of disease progression and serious complications were regarded as the success criteria of the operation. Surgical success rate was evaluated. Surgery-associated complications were recorded. Results:The average follow-up time was(11.52±12.44) months. After the microsurgery, IOP decreased from(33.12±9.25) mmHg to(14.23±3.44) mmHg( P<0.01); The ACD increased from(1.23±0.46) mm to(2.86±0.62) mm, and the median number of glaucoma medications dropped from 3(3,4) to 3(0,3) at final follow-up visit( P<0.05). There were no significant differences in BCVA( P=0.196) and the degrees of angle closure(AC) ( P=0.478) before and after operation. The total surgical success rate was 86.2%(25/29) at the final follow-up visit. Two eyes suffered from local choroidal detachment which recovered within 2 weeks with medical treatment. Conclusion:LPPV plus PCP plus IOL plus PC is a safe and effective novel surgical procedure in the treatment of nanophthalmic glaucoma patients with uncontrolled IOP after peripheral iridectomy. It could significantly decrease IOP, increase the depth of ACD, reduce the number of glaucoma medications and maintain BCVA. It can be considered as a first choice for the surgical management for patients with a such condition.

Objective:To investigate the prognosis of severe hyperbilirubinemia in full-term infants who met the exchange transfusion criteria and were treated by blood exchange transfusion and phototherapy.Methods:A total of 168 full-term infants with severe hyperbilirubinemia who met the criteria for exchange transfusion and were hospitalized in the Neonatology Department of seven tertiary hospitals in Hebei Province from June 2017 to December 2018 were retrospectively included. According to the treatment protocol, they were divided into two groups: exchange transfusion group (38 cases) and phototherapy group (130 cases). Two independent sample t-test and Chi-square test were used to compare the clinical manifestations and follow-up results between the two groups. Multivariate logistic regression was used to analyze the risk factors for poor prognosis. Results:Neonatal severe hyperbilirubinemia in the exchange transfusion and phototherapy group were both mainly caused by hemolytic disease [42.1%(16/38) and 29.2%(38/130)], sepsis [28.9%(11/38) and 11.5%(15/130)] and early-onset breastfeeding jaundice [15.8%(6/38) and 11.5%(15/130)]. Total serum bilirubin level on admission in the exchange transfusion group was significantly higher than that in the phototherapy group [(531.7±141.3) vs (440.0±67.4) μmol/L, t=3.870, P<0.001]. Moreover, the percentage of patients with mild, moderate and severe acute bilirubin encephalopathy in the exchange transfusion group were higher than those in the phototherapy group [15.8%(6/38) vs 3.8%(5/130), 7.9%(3/38) vs 0.8%(1/130), 13.2%(5/38) vs 0.0%(0/130); χ2=29.119, P<0.001]. Among the 168 patients, 135 were followed up to 18-36 months of age and 12 showed poor prognosis (developmental retardation or hearing impairment) with four in the exchange transfusion group (12.9%, 4/31) and eight in the phototherapy group (7.7%, 8/104). Multivariate logistic regression analysis showed that for full-term infants with severe hyperbilirubinemia who met the exchange transfusion criteria, phototherapy alone without blood exchange transfusion as well as severe ABE were risk factors for poor prognosis ( OR=14.407, 95% CI: 1.101-88.528, P=0.042; OR=16.561, 95% CI: 4.042-67.850, P<0.001). Conclusions:Full-term infants who have severe hyperbilirubinemia and meet the exchange transfusion criteria should be actively treated with blood exchange transfusion, especially for those with severe ABE, so as to improve the prognosis.

Objective: To investigate the effect of lncRNA SBF2-AS1 on epithelial-mesenchymal transition (EMT) of cervical cancer HeLa cell via regulating miR-140-5p/VEGFA (vascular endothelial growth factor A) axis. Methods: After cell culture and transfection, the cells were divided into 5 groups: NC group, miR-140-5p mimic group, miR-140-5p mimic+pcDNA-VEGFA group, si-lncRNA SBF2-AS1+pcDNA-VEGFA group and si-lncRNA SBF2-AS1+miR-140-5p mimic group. The expression level of lncRNA SBF2-AS1 in cervical cancer tissues and cell lines was detected by qPCR. The targeted relationship between lncRNA SBF2-AS1, miR-140-5p and VEGFA was confirmed by Dual luciferase reporter gene assay. The expression levels of VEGFA and EMT-related proteins N-cadherin, Vimentin and E-cadherin in HeLa cells were detected by WB. The invasion and migration of HeLa cells were detected by Transwell. Results: lncRNA SBF2-AS1 was highly expressed in cervical cancer tissues and cell lines (P<0.05 or P<0.01). Dual luciferase reporter gene assay confirmed that lncRNASBF2-AS1 targetedly combined with miR-140-5p and VEGFAwas a target gene of miR-140-5p (P< 0.05). Knockdown of lncRNA SBF2-AS1 inhibited invasion and migration as well as EMT of HeLa cells. Further experiment confirmed that lncRNA SBF2-AS1 up-regulated the expression level of VEGFA via miR-140-5p, thereby promoting invasion, migration and EMT of HeLa cells. Conclusion: lncRNASBF2-AS1 promotes EMT of HeLa cells via miR-140-5p/VEGFAaxis.
