Background: Cerebral small vessel disease (CSVD) is a common disease in the elderly, and its pathogenesis is still being explored. Glymphatic clearance function can be evaluated by diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) index. This study aims to investigate the changes in glymphatic clearance function in CSVD patients and its relationship with imaging markers and risk factors of CSVD.

Arbuscular mycorrhizal (AM) fungi play an important role in organic matter (OM) stabilization in Fe ore tailings for eco-engineered soil formation. However, little has been understood about the AM fungi-derived organic signature and organo-mineral interactions at the submicron scale. In this study, a compartmentalized cultivation system was used to investigate the role of AM fungi in OM formation and stabilization in tailings.

Article Synopsis
  • Mineral weathering and pH neutralization are essential for transforming alkaline Fe-ore tailings into soil-like growth media (Technosols), and the presence of sulfur oxidizing bacteria (SOB) can speed up these processes.
  • A study demonstrated that adding elemental sulfur and organic matter enriched the indigenous SOB community in tailings, leading to increased sulfur oxidation, pH neutralization, and mineral weathering.
  • The findings suggest that combining sulfur and plant biomass can boost SOB growth in tailings, promoting mineral weathering and facilitating the creation of sustainable soil for rehabilitating Fe ore tailings.

The present study aimed to characterise the adaptive growth and acidogenic fermentation performance of haloalkaliphilic bacteria sourced from field biofilms colonising seawater-treated bauxite residue, under moderate and extremely alkaline pH conditions (8.5 to 10.8) and coupled saline (EC ≈ 50 mS/cm) conditions.

Bioneutralization of alkaline bauxite residues (BR) may be achieved through in situ organic acids produced from fermentative decomposition of carbohydrates-rich organic matters (e.g., plant residues), which are driven by organophilic and heterotrophic prokaryotes tolerant of extremely saline and alkaline conditions.

Background And Aim: Maternal near-miss (MNM) surveillance has been developed to identify severe complications in pregnancy since 2011 in China. However, very little is known about MNM in China. This study aims to explore the prevalence of MNM, the risk factors, and perinatal outcomes using the WHO near-miss approach in a developed Chinese province.

Objectives: The aim of this study was to assess patient safety culture (PSC) in maternal and child health (MCH) institutions in China and its individual, organizational, and regional variations.

Methods: Using the PSC survey for MCH institutions (PSCS-MCHI), 2021 valid respondents from 25 participating institutions were investigated in three regions (Beijing, Zhejiang, and Jiangxi) of China. Patient safety culture and its subscale scores (1-5) and factors associated with PSC as revealed by multilevel modeling.

UNICEF Baby Friendly Initiative (BFHI) is the global standard for maternity and community services requiring all practitioners to be trained to support mothers in the essential skills of supporting positioning and attachment, and hand expression. These studies aim to rigorously assess knowledge in nurses, midwives, and doctors in these skills, tested before and after watching short videos demonstrating these skills. Practitioners were attending BFHI education, and the video study was additional.

Aim: We examined the effects of a family-support programme for pregnant women with foetal abnormalities in terms of family support, depression, and post-traumatic stress symptoms.

Method: A randomized controlled trial was conducted from November 2016 to June 2017. A total of 124 pregnant women with foetal abnormalities were recruited and randomly assigned to the intervention group that received a family-support programme or control group that received only routine care.

Objective: To explore the prevalence of maternal near miss (MNM) and adverse pregnancy outcomes in Zhejiang province by MNM surveillance system.

Methods: A cross-sectional study was conducted during 2012 and 2013. All MNM cases were recruited from the MNM surveillance system.

Background: The management of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL) is still controversial and it is advisable to make a triage for these two cytological abnormalities. P16(INK4) (P16) has been shown to be a potential biomarker for predicting high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer. The aim of the study was to determine the value of P16 expression by immunostaining method compared with high-risk human papillomavirus (HR-HPV) DNA test in the triage of ASCUS/LSIL women.

Objective: to explore the value of P16 in the predication of high-grade cervical intraepithelial (HGCIN) by P16 expression in cervical specimens.

Methods: one hundred ninety-two residual ThinPrep samples were collected and detected by HPV DNA test and P16 detected by immunocytochemistry. All women underwent colposcopy and histological examination of biopsy specimen if needed.

Objective: To compare the efficacy and safety of midazolam combined with fentanyl and propofol combined with fentanyl as conscious sedation in oocyte retrieval of in vitro fertilization and embryo transplantation (IVF-ET).

Methods: Eighty patients receiving IVE-ET were randomly divided into midazolam combined with fentanyl group (midazolam group) and propofol combined with fentanyl group (propofol group). Antalgic effects, circulation status (blood pressure, heart rate), respiration status (rate, oxygen saturation and respiration depression) during operation, nausea and vomiting, and amnestic effects after operation were compared.
