Objective:To observe the effect of breastfeeding on the incidence of retinopathy of prematurity (ROP).Methods:A retrospective clinical study. From June 2017 to December 2019, 1256 eyes of 628 premature infants who were born in Ningbo Women and Children's Hospital and were screened for ROP were included in the study. Among them, there were in 325 males (650 eyes) and 303 females (606 eyes). According to the feeding situation, premature infants were divided into breastfeeding (research) group and formula feeding (control) group, with 390 cases of 780 eyes and 238 cases of 476 eyes, respectively. The changes in the retina of the fundus of the two groups of premature infants during the observation period were compared. The qualitative data comparison between groups was performed by the χ2 test; the quantitative data comparison was performed by the two independent sample t test. Results:The sex ratio of premature infants in the study group and control group ( χ2=0.217), birth weight ( t=0.728), gestational age at birth ( t=0.351), Apgar score at birth ( t=0.816), oxygen inhalation time ( t=0.427), were compared with the length of stay in the neonatal intensive care unit ( t=1.580), the difference was not statistically significant ( P>0.05). Among the 390 cases in the study group, 108 cases (27.7%, 108/390) and 282 cases (72.3%, 282/390) were with or without ROP, respectively; in the 238 cases in the control group, 86 (36.1%, 86/238) were with ROP, 152 (63.9%, 152/238) cases were without ROP. There was a statistically significant difference in the incidence of ROP between the two groups ( χ2=4.934, P=0.026). Among the 108 cases of ROP in the study group, 50 (12.8%, 50/108), 35 (9.0%, 35/108), 23 (5.9%, 23/108) cases were in stage 1, 2 and 3, respectively. Among the 86 ROP cases in the control group, stages 1, 2 and 3 were 25 (10.5%, 25/86), 40 (16.8%, 40/86), and 21 (8.8%, 21/86), respectively. In the comparison of ROP staging between the two groups, the difference in stage 1 was not statistically significant ( χ2=0.754, P>0.05), and the difference in stage 2 and above was statistically significant ( χ2=11.400, P<0.05). Conclusion:Breastfeeding may reduce the incidence and severity of ROP.

Aim To explore new ways for developing anticancer drugs by the separation of pigment from Fu-sarium species JN158 ( Fusarium sp JN158 ) , the iden-tification of its structure, the screening of anticancer components and the study of its partial mechanism. Methods Pigment separation was done by HPLC, structural analysis by UV, IR, NMR, the screening of anticancer activity by MTT. Western blot was used to analyze the protein expression of CyclinD1, NF-κB, VEGF in tumor cells. Results The results showed that the pigment from Fusarium produced a total of six different peaks, of which peak Ⅵ was the anthocya-nins. Its molecular weight is about 382, molecular for-mula is C17 H18 O10 . According to investigation, this pig-ment was probably a new compound, which could in-hibit the proliferation of MCF-7 cells markedly ( IC50:0.011mmol·L-1 ,P<0.05;the control medicine ube-nimex IC50:10 mmol · L-1 ) in a concentration-de-pendent manner, and had no effect on human umbilical cord intravenous endotheliocyte ( HUVEC ) . The influ-ence on the gene expression of CyclinD1, NF-κB, VEGF in MCF-7 cells varied with the concentration of this compound. The Western blot results showed that VI pigment compound inhibited CyclinD1, NF-κB, VEGF gene expression (P<0.05 or 0. 01),compared with the control group. Conclusion The Ⅵ pigment compound from Fusarium sp JN158 could inhibit MCF-7 proliferation by inhibiting CyclinD1, NF-κB, VEGF gene expression. The compound may be a promising compound against breast cancer.
