Self-esteem, depression, anxiety and sexual function in Mayer-Rokitansky-Küster-Hauser syndrome with neovagina: A case series.

Background: The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare condition with significant psychological implications. However, our understanding of its impact on postoperative sexual function and mental health is still limited.

Aim: Evaluate the mental health status and sexual functioning of women with MRKH syndrome after vaginoplasty surgery.

Catalpol ameliorates depressive-like behaviors in CUMS mice via oxidative stress-mediated NLRP3 inflammasome and neuroinflammation.

The purpose of the present study was to investigate whether catalpol exhibited neuroprotective effects in chronic unpredictable mild stress (CUMS) mice through oxidative stress-mediated nucleotide-binding oligomerization domain, leucine-rich repeat, and pyrin-domain-containing 3 (NLRP3) inflammasome and neuroinflammation. Deficits in behavioral tests, including open field test (OFT), forced swim test (FST), and elevated plus-maze test (EPM), were ameliorated following catalpol administration. To study the potential mechanism, western blots, quantitative real-time PCR (qRT-PCR) analysis and immunofluorescence imaging were performed on the hippocampus samples.

Cost-effectiveness analysis of a community-based colorectal cancer screening program in Shanghai, China.

Objective: This study investigated the cost-effectiveness of a community-based colorectal cancer-screening program (C-CRCSP) in Shanghai, China, among the residents in the urban, suburban and rural areas.

Methods: A Markov model was constructed to evaluate the cost-effectiveness of a 25-year annual C-CRCSP including 100 000 populations. Cost-effectiveness was determined by the incremental cost-effectiveness ratio (ICER); referring to either life-years gained, or quality-adjusted life-years (QALYs) gained.

The new targets of ouabain in retinal interneurons of Sprague-Dawley rats.

Ouabain is both a cardiac glycoside used in therapy of congestive heart failure and an endogenous steroid hormone. It specifically binds to Na(+), K(+)-ATPase (NKA) and blocks its activity. Overdose of ouabain induces retinal damage.

Preferential regeneration of photoreceptor from Müller glia after retinal degeneration in adult rat.

To determine whether photoreceptor degeneration can stimulate Müller glia to transdifferentiate into neurons in adult mammalian retina, N-methyl-N-nitrosourea (MNU) was injected to induce complete loss of photoreceptors. Following MNU administration, Müller glia underwent reactive gliosis characterized by up-regulation of glial fibrillar acidic protein and nestin, and initiated proliferation through the cyclin D1 and D3 related pathways. Some Müller glia-derived cells were induced to express rhodopsin exclusively.

Sonic hedgehog promotes stem-cell potential of Müller glia in the mammalian retina.

Müller glia have been demonstrated to display stem-cell properties after retinal damage. Here, we report this potential can be regulated by Sonic hedgehog (Shh) signaling. Shh can stimulate proliferation of Müller glia through its receptor and target gene expressed on them, furthermore, Shh-treated Müller glia are induced to dedifferentiate by expressing progenitor-specific markers, and then adopt cell fate of rod photoreceptor.

[Role of different oxygen concentration and different period of oxygen exposure in pathogenesis of retinopathy in neonatal mice].

Objective: To evaluate the role of different oxygen concentration (FiO2) and different period of oxygen exposure on oxygen-induced retinopathy (OIR) in neonatal mice and to provide evidences for proper clinical oxygen therapy.

Methods: Two hundred and four 7-day-old (P7) C57BL/6J mice were exposed to different FiO2 30%, 50% and 75% for 5, 7 and 9 days. The mice were divided into eight groups: groups 1 - 3 (n = 24 in each) were exposed to 30% oxygen for 5, 7 and 9 days, respectively; groups 4 - 6 (n = 24 in each) were exposed to 50% oxygen for 5, 7 and 9 days, respectively; group 7 (n = 30) was exposed to 75% hyperoxia for 5 days; group 8 (n = 30) was exposed to room air.
