The survey on the hesitant status of rubella-containing vaccine (RCV) vaccination was conducted among 2 141 women of childbearing age in four provinces, Liaoning, Jiangsu, Zhejiang, and Anhui, from May 2017 to March 2018. Among the 2 141 study participants, a total of 38.21% (818) of women of childbearing age were aware of rubella and 21.25% (455) of women of childbearing age knew about RCV. Among the 455 women of childbearing age who were aware of RCV, 262 (57.58%) were willing to be vaccinated with RCV; 304 women of childbearing age (66.81%) tended to be vaccinated with RCV free of charge. Among the 193 women of childbearing age who did not want to be vaccinated or did not decide whether they preferred to be vaccinated with RCV, no one around them was vaccinated (89, 46.11%) and fear of vaccine safety (70, 36.27%) were the main reasons for hesitation to receive RCV.

The clinical data, laboratory testing, genetic testing results, diagnosis and treatment process of a child with PERCHING syndrome diagnosed and treated in the Department of Neonatology, the Third Affiliated Hospital of Zhengzhou University in June 2022 were retrospectively analyzed, and the relevant literatures were reviewed.The proband mainly presented with dyspnea and feeding difficulties after delivery, facial nevus flammeus, protrusion of eyes, small fissure of eyes, wide nasal root, limited opening of mouth, slightly high palatal arch, special posture, cryptorchid, hypospadias, and high muscle tone of limbs.Magnetic resonance imaging of the brain suggested possible agenesis of corpus callosum.Genetic testing showed complex heterozygous variations in the KLHL7 gene, and the two mutation sites have not been previously reported.A case of PERCHING syndrome caused by the KLHL7 gene mutation in China was reported for the first time, which provided new ideas for the diagnosis and treatment of children with PERCHING syndrome and reliable genetic evidence for family reproduction.
