Nearly half a century,an increasing number of studies have found that the puberty of human being is at early trends.Puberty is the process of physical changes involving reproductive system maturation and the acquisition of fertility,by the combination effects of nervous system,endocrine system and the environment.Pubertal timing is a relative concept and the process of pubertal development can be shown as early,timely or relatively late as compared with a reference group.This article mainly focuses on related influencing factors of pubertal timing including genetic factor,childhood obesity,growth pattern (intrauterine growth retardation,catchup growth,adiposity rebound),psychosocial stress (poor family emotional environment,father absence,international adoption),environmental endocrine disrupting chemicals with their mechanism and significance.The exploration of relevant risk factors of early puberty can provide scientific evidence for formulating relevant policies and targeted prevention.

In coloreetal cancer,there are multiple abnormally expressed microRNA (miRNA),suggesting that the miRNA may be involved in tumor development process.Recently,more and more evidence shows that miRNA are more stable in the blood,compared with mRNA,which makes circulating miRNA are helpful to become the non-invasive tumor marker for the diagnosis,treatment and prognosis evaluation in coloreetal cancer.

Objective To investigate the analgesic effect of epidural labor analgesia with contin-uous background infusion and its impact on obstetric outcome.Methods This was a retrospective co-hort study.In the two months of march 2014 and march 201 5,503 nulliparas women who had re-ceived epidural analgesia for labor were enrolled and assigned to two different study groups according to their analgesic protocol.Two hundred and fifty-eight nulliparas in group C received only patient-controlled analgesia while two hundred and forty-five nulliparas in group P received patient-controlled analgesia with continuous background infusion.The basic and perinatal data of all enrolled nulliparas women were collected and analyzed to compare the analgesic effect and the impact on obstetric risk of two different analgesic protocol.Results The NRS pain score during the second labor stage was lower in group P [3 (3-4)scores vs.5 (4-5)scores](P <0.001).The second stage prolonged [50 (29-82) min vs.38 (24-62)min](P =0.001)and intrapartum hemorrhage increased [200 (100-250)ml vs. 1 50 (100-200)ml](P =0.003)in group P.There were no significant differences between the two groups with regard to the delivery mode (P =0.656)and the morbidity of postpartum hemorrhage (9.8% vs.10.9%,P =0.697).Analgesic protocol with background infusion was not associated with postpartum hemorrhage,instrumental delivery risk and cesarean risk.Conclusion Epidural labor an-algesia with continuous background infusion provided more effective analgesia in nulliparas,without additional obstetric risk.

Infiltrated immune cells and cytokines in the tumor microenvironment may play different functions that appear tightly related to clinical outcomes.Radiotherapy mainly kills tumor cells through radiobio-logical effect,meanwhile it can indirectly change tumor immunologic microenvironment,and has a local or dis-tant anti-tumor immunological effect cooperatively.Animal experiments and clinical trials of radiotherapy com-bined with immunotherapy display well applied prospects,but the mode of radiotherapy in combined treatment needs further research.
