National labor and delivery survey and the study of labor patterns in Chinese women. ZHANG Jun*，ZHANG Jin-wen*，LIU Ming，HUA Jing，SHI Qi，LI Sheng-hui，QI Hong-bo，DUAN Tao. 2016, 32(8): 719-722.  DOI: 10.7504/fk2016070103 Abstract ( )   Abstract:Two nationwide multicenter studies are currently being conducted，the national labor and delivery survey and the study of labor patterns in Chinese women. The purposes of these studies are as follows：（1） to describe the contemporary situation of obstetric complications and cesarean delivery in China，and to identify the main factors contributing to cesarean delivery;（2） to describe the contemporary labor patterns of Chinese women in order to provide evidence for proposing the partogram of China;（3） to explore the optimal timing for cesarean section when labor is prolonged or arrested. We will state the purposes, actual measures and the significance of the the national labor and delivery survey and the study of labor patterns in Chinese women.

Review on the latent phase of labor. LIU Xing-hui，HE Guo-lin. 2016, 32(8): 722-725.  DOI: 10.7504/fk2016070104 Abstract ( )   Abstract:The latent phase of labor is an important part of the birth process，and its definition has had a major change now.The extended duration of the latent phase is to reduce obstetric intervention and to lower the rate of intrapartum cesarean delivery.Admission timing is closely related to intrapartum cesarean section rate，and the timing of admission is very important.

Timing of delivery of women with maternal-fetal complications. LI Jun-nan，QI Hong-bo. 2016, 32(8): 726-730.  DOI: 10.7504/fk2016070105 Abstract ( )   Abstract:The timing of deliveries is the optimal outcome for the mother，baby，or both，due to conditions that result in worse outcomes if pregnancy is allowed to continue.When complicated pregnancy occurs，most mothers fail to labor; therefore，prior to the decision to induce labor，the optimal delivery timing is not only the key factor for the perinatal outcome，but also the clinical representation of obstetrical precision medicine.Time of delivery is neither static nor rigid.The maternal and child safety is our first concern.Individualized optimum methods and timing of delivery should be planned.The most suitable is the best.These conditions may be categorized as fetal issues （fetal growth restriction，twin pregnancy），maternal and obstetrical issues （hypertension in pregnancy，diabetes mellitus in pregnancy，prelabor rupture of membrane，prior stillbirth-unexplained），placental and uterine issues （placenta previa，placenta accreta/increta/percreta，prior classical cesarean，prior myomectomy，uterine rupture）.This paper summarized the delivery timing for these conditions.

Labor management and intervention. LIU Ming. 2016, 32(8): 730-734.  DOI: 10.7504/fk2016070106 Abstract ( )   Abstract: With significant change in contemporary obstetric population peculiarity and current obstetric interventions, the utility of traditional labor curve has been greatly challenged. In recent years, a series of labor studies have been reported by Zhang et al. Based on these contemporary data, several organizations have renewed labor curve. However, Zhang examined the labor patterns retrospectively according to labor data in the United States, so further research should be evaluated in Chinese women. Clinicians are now most concerned about how to predict and manage labor progression before the Chinese labor curve is confirmed.

Timing and mode of delivery in patients with hypertensive disorders of pregnancy. GENG Li，HU Yan-xin，MA Run-mei. 2016, 32(8): 734-738.  DOI: 10.7504/fk2016070107 Abstract ( )   Abstract: Hypertensive disorders of pregnancy （HDP） is a unique clinical syndrome with multiple organ damages after 20th weeks of gestational age.Although termination of pregnancy is the most effective management option for the mother，the appropriate timing and mode of delivery is most important to improve maternal and neonatal outcomes.We hereby reviewed the related literatures together with our own experiences to address the keypoints of the issues.

Operative vaginal delivery. XU Huan，LI Xiao-tian. 2016, 32(8): 738-741.  DOI: 10.7504/fk2016070108 Abstract ( )   Abstract: Operative vaginal delivery refers to a delivery in which the operator uses forceps or a vacuum device to extract the fetus from the vagina.The number of forceps deliveries is falling possibly due to the lack of experience and competence in obstetricians.The purpose of this paper is to discuss the indication，skill，complication and choice operative mode of the operative vaginal delivery.

Prevention and management of shoulder dystocia. LIU Qun-ying*，WANG Xie-tong*. 2016, 32(8): 745-748.  DOI: 10.7504/fk2016070110 Abstract ( )   Abstract: Shoulder dystocia is an unpredictable obstetrical event of high risk.The incidence of shoulder dystocia is 0.2%～3.0%. It has high perinatal mortality and morbidity.Fetal brachial plexus injury （BPI） is the most common fetal complication occurring in 4%～40% of cases.Obstetricians should be aware of the existing risk factors，always being alert to the possibility of shoulder dystocia in all labors.Optimal management of shoulder dystocia requires appropriate management at the time it occurs.This article reviews the current evidence regarding the possible prediction，prevention and management of shoulder dystocia.

Vaginal birth after cesarean delivery. LI Bo-ya, YANG Hui-xia. 2016, 32(8): 748-753.  DOI: 10.7504/fk2016070111 Abstract ( )   Abstract: Vaginal birth after cesarean delivery is always a controversy，especially after the implementation of the two-child policy. There is a consensus that planned VBAC is a clinically safe choice for the majority of women with a single previous lower segment caesarean delivery. This article provides evidence-based recommendations for the antenatal and intrapartum management of women undergoing VBAC.

Prevention of neonate birth injury. ZHANG Li-wen*，GU Hang. 2016, 32(8): 753-756.  DOI: 10.7504/fk2016070112 Abstract ( )   Abstract: Neonatal birth injury is defined as an impairment of the neonate's body function or structure caused by physical forces or other adverse events at birth. Birth injury can occur in any parts of the neonate's body.Most injuries are minor and self-limited problems with a good prognosis.However，a small portion of the injuries have severe sequelae that may result in mortality.Prevention must be emphasized to prevent any potential injuries.Birth injury must be identified timely，and a specialist must be asked for to provide an urgent treatment for the neonates.
