Ultra-long room temperature phosphorescence(URTP) has been increasingly recognized in pure organic luminophor in recent years. Through a simpler molecular design and charge separation-recombination pathway, organic luminophor can achieve even better URTP properties. In this work, we achieved URTP in a system of host-guest doped benzophenone derivatives whose phosphorescence is visible to the naked eye. The differences in the wavelength lifetimes of luminescent emission correspond to different photophysical mechanisms. Through a combination of theoretical calculations and experiments, the host acts as a powerful substrate that restricts the motion of the guest and inhibits the non-radiative transitions of the guest, accompanied by a charge transfer separation-recombination process between the host and the guest, resulting in an URTP phenomenon. Transient absorption results demonstrate the existence of a charge-separated state. The design strategy via charge separation is generic and easy to implement,providing a direction for the future design of doped URTP.

Primary undifferentiated embryonal sarcoma （UES） of the liver, also called malignant mesenchymoma of the liver, is a rare hepatic malignancy. It arises from the mesoderm and comprises more than two types of sarcomas. UES can occur at any site of the body; common sites include the retroperitoneum and the lower extremities. Only a few cases of UES have been reported worldwide.1 In this study, we retrospectively examined the clinical data of 11 patients with UES between January 2000 and November 2011 at the People＇s Liberation Army General Hospital.

Background: The growth of adolescents is affected by economic development and education levels. We investigated the first spermatorrhea age of adolescents in urban area and in rural area of Jiangsu province, China. Methods: The data were obtained through anonymous questionnaire by using cross-sectional methods. From May 2016 to March 2017 in Jiangsu province, China, a total of 2131 Han nationality students were enrolled in cluster. The survey was contained date of birth, age, grade, age of first spermatorrhea and how long ago of the first spermatorrhea, all data were analyzed by Prism 8.0. Results: The questionnaire accounted for response was 97.3%, and the effective rate was 96.3%. The mean age of first spermatorrhea was (13.7 ± 1.5) years old, which included 13.6 ± 1.4 years in urban and 13.9 ± 1.5 years in rural. The first spermatorrhea occurred in the fifth and sixth grade primary school, and 1, 2, 3 grades of junior high school were 3.5%, 13%, 27.4%, 28.5% and 15.1%, respectively. There was 62.3% of first spermatorrhea occurred in summer. The rate of spermatorrhea with natural occurrence accounted for 95.1%, and with active accounted for 4.9%. Conclusions: Compared with rural area, the age of the first spermatorrhea of males in urban area is significant earlier. The adolescent’s first spermatozoa were mostly occurred in summer. The relevant physical and reproductive education should be started from the third grade of primary school. The reproductive health education should be carried out when the youth are 7 years old.
