Expression of Angiopoietin-2 in Lung Tissue of Juvenile SD Rats with Lipopolysaccharide-Induced Acute Lung Injury and the Role of Ulinastatin.

This study aimed to observe the expression of angiopoietin-2 (Ang-2) in the lung tissue of juvenile SD rats with lipopolysaccharide (LPS)-induced acute lung injury (ALI) and to clarify the role of ulinastatin (UTI). Ninety 18-21-day-old juvenile SD male rats were randomly divided into five groups (n = 18). ALI rat model was established by intraperitoneal injection of LPS (LPS 10 mg/kg), while the control group was given the same dose of normal saline.

New AMH cutoff values for warning of decreased ovarian response based on MCL characteristics in young women: a retrospective study using a propensity score-matching analysis.

Background: Menstrual cycle length (MCL) and ovarian response varies widely among women of childbearing age. They are provided with anti-Mu¨llerian hormone (AMH) cutoffs for "normal" and "weakened" ovarian responses, which give an early warning of the onset of decreased ovarian response.

Methods: This was a retrospective study in women aged 21 to 35 years with MCLs of 21-35 days receiving in vitro fertilization (IVF) treatment at Center for Reproductive Medicine from October 2018 to October 2021.

Increasing the Grain Yield and Grain Protein Content of Common Wheat () by Introducing Missense Mutations in the Gene.

Grain yield (GY) and grain protein content (GPC) are important traits for wheat breeding and production; however, they are usually negatively correlated. The gene is the most important domestication gene in cultivated wheat because it influences many traits, including GY and GPC. Allelic variations in the gene may positively affect both GY and GPC.

Adverse obstetric and perinatal outcomes in 2333 singleton pregnancies conceived after different endometrial preparation protocols: a retrospective study in China.

Backgroup: Frozen-thawed embryo transfer is rising worldwide. One adverse effect of programmed frozen embryo transfer (FET) reported in some studies is an increased risk of adverse obstetric and perinatal outcomes. Meanwhile, body mass index (BMI) also has adverse effect on obstetric and perinatal outcomes.

Heterotopic cervical pregnancy: Case report and literature review.

Cervical pregnancy (CP) is a rare form of ectopic pregnancy (EP) in which the embryo implants and grows inside the endocervical canal. Heterotopic cervical pregnancy is an even rare form of EP, in which at least two embryos are simultaneously implanted in different sites and only one in the uterine cavity. Although many treatment approaches are available, the ideal management remains unclear.

[Nutritional support in children with pneumonia on mechanical ventilation by short-peptide enteral nutrition formula].

Objective: To observe the incidence of malnutrition and nutritional risk in children with pneumonia on mechanical ventilation in the pediatric intensive care unit (PICU), and to explore the nutritional support effect of short-peptide enteral nutrition formula.

Methods: A total of 68 children with severe pneumonia who were hospitalized in the PICU from October 2017 to October 2018 and required mechanical ventilation were enrolled for a prospective randomized controlled study. The children were randomly divided into a control group and an experimental group.
