Aim: To study the antiviral effect of Chinese medicine jiaweisinisan (JWSNS) on hepatitis B virus (HBV) infection in transgenic mice (TGM).
Methods: Twenty two 6-8 wk old HBV TGM in the third generation were divided into TGM control group and TGM treated group randomly. The normal control group included ten normal BC 57L/6 mice at the same age. The mice in treated group were administrated with JWSNS at the concentration of 4 g/mL and the dosage of 50 g/kg per d for 30 d, while the mice in TGM control group and normal control group were administrated with normal saline at the same dosage and the same time. Polymerase chain reaction (PCR) was used to assess the contents of HBV DNA in serum of HBV TGM before and after treatments, whereas blot hybridization was utilized to measure the contents of HBV DNA in the liver of both HBV TGM and normal BC 57L/6 mice.
Results: The levels of serum HBV DNA in TGM treated group were remarkably decreased after the treatment of JWSNS (7.662+/-0.78 vs 5.22+/-3.14, P < 0.05), while there was no obvious change after administration of normal saline in TGM control group (7.125+/-4.26 vs 8.932+/-5.12, P > 0.05). The OD values of HBV DNA in the livers of the mice in TGM treated group were significantly lower than those of TGM control group (0.274+/-0.096 vs 0.432+/-0.119, P < 0.01).
Conclusion: JWSNS exerts suppressive effects on HBV DNA in the serum and liver of TGM.

Importance: Access to appropriate postpartum care is essential for improving maternal health outcomes and promoting maternal health equity.
Objective: To analyze the impact of the Nurse-Family Partnership (NFP) home visiting program on use of routine and emergency postpartum care.
Design, Setting, And Participants: This study was a secondary analysis of a randomized clinical trial that enrolled eligible participants between 2016 and 2020 to receive NFP or usual care from a South Carolina Medicaid program.

Importance: Injuries from firearms and motor vehicle crashes (MVCs) are the leading causes of death among US children and youths aged 0 to 19 years. Examining the intersections of age group, sex, race, and ethnicity is essential to focus prevention efforts.
Objective: To examine firearm and motor vehicle fatality rates by population subgroups and analyze changes over time.

Chronic exposure to prenatal stress can impair neurogenesis and lead to irreversible cognitive and neuropsychiatric abnormalities in offspring. The retina is part of the nervous system; however, the impacts of prenatal stress on retinal neurogenesis and visual function remain unclear. This study examined how elevated prenatal glucocorticoid levels differentially affect retinal development in the offspring of pregnant mice exposed to chronic unpredictable mild stress (CUMS).

To investigate the association of NANOG polymorphisms with oral leukoplakia. In this case-control study, 68 cases of oral leukoplakia, and 21 of normal oral mucosa (control) were submitted to genotyping of tagSNPs polymorphisms: rs877716 and rs10845877 in NANOG, through real-time polymerase chain reaction (PCR). Pearson's chi-squared and Fisher's exact statistical tests were used, with a significance of 5%.

Polyhydroxyalkanoates (PHAs) have attracted broad interest as promising sustainable materials to address plastic pollution and resource scarcity. However, the chemical synthesis of stereoregular PHAs via ring-opening polymerization (ROP) has long been an elusive endeavor. In this contribution, we exploited a robust spiro-salen yttrium complex (Y3) as the catalyst to successfully prepare syndiotactic PHAs with diverse pendent groups.
