[Mechanism of protective effect of resveratrol on poor ovarian response in mice].

This study aims to investigate the therapeutic effects and potential mechanisms of resveratrol(Res) on poor ovarian response(POR) in mice. The common target genes shared by Res and POR were predicted by network pharmacology, used for Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment, and then validated by animal experiments. The mice with regular estrous cycle after screening were randomized into normal, POR, and low-and high-dose(20 and 40 mg·kg~(-1), respectively) Res groups.

Study on the mechanism of electroacupuncture regulating macrophage polarization to improve ulcerative colitis in rats.

Objectives: To investigate the effect of electroacupuncture(EA) at "Changbing Decoction" on alleviating ulcerative colitis (UC) and regulating the polarization of colonic macrophages in rats, so as to explore its mechanisms underlying improvement of UC.

Methods: Twenty-six male SD rats were randomly divided into 4 groups：normal group(6 rats), model group(8 rats), EA group(6 rats), and western medication group(6 rats). The rat model of UC was established by using 5% dextran sulfate sodium (DSS) solution drinking water for 7 days, followed by drinking 1% DSS solution during treatment period.

[Effect of electroacupuncture on colonic autophagy and AMPK/mTOR signaling pathway in rats with acute ulcerative colitis].

Objective: To observe the effect of electroacupuncture （EA） at "Zhongwan" （CV12）, "Tianshu" （ST25） and "Shangjuxu" （ST37） （an acupoint prescription "Changbingfang" for treatment of intestinal disorders） on autophagy and expression of AMPK/mTOR signaling pathway in rats with ulcerative colitis （UC）, so as to explore its mechanism underlying improvement of UC.

Methods: Thirty-two male SD rats were randomly divided into control, model, medication and EA groups, with 8 rats in each group. The UC model was established by free drinking of 5% dextran sulfate sodium salt solution for 7 days.

Deleted in lymphocytic leukemia 2 (DLEU2): a possible biomarker that holds promise for future diagnosis and treatment of cancer.

The mechanism of deleted in lymphocytic leukemia 2 (DLEU2)-long non-coding RNA in tumors has become a major point of interest in recent research related to the occurrence and development of a variety of tumors. Recent studies have shown that the long non-coding RNA DLEU2 (lncRNA-DLEU2) can cause abnormal gene or protein expression by acting on downstream targets in cancers. At present, most lncRNA-DLEU2 play the role of oncogenes in different tumors, which are mostly associated with tumor characteristics, such as proliferation, migration, invasion, and apoptosis.

[Acupuncture of "Zhibian (BL 54) through Shuidao (ST 28)" for female stress urinary incontinence: a randomized controlled trial].

Objective: To observe effect of "Zhibian (BL 54) through Shuidao (ST 28)" acupuncture for quality of life of female patients with stress urinary incontinence.

Methods: A total of 90 female patients were randomly divided into an observation group and a control group, 45 cases in each group. The patients in the observation group were treated with "Zhibian (BL 54) through Shuidao (ST 28)" acupuncture method, and the patients in the control group were treated with non-permeable sham acupuncture at Zhibian (BL 54).

Annonaceous acetogenin mimic AA005 suppresses human colon cancer cell growth in vivo through downregulation of Mcl-1.

Annonaceous acetogenins are a well-established family of natural products with significant bioactivities, especially high cytotoxic and antitumor activities. AA005 is an annonaceous acetogenin mimic that has shown significant cytotoxicity against a variety of cancer cell lines, but its in vivo antitumor effects have not been demonstrated so far, and its anticancer mechanisms remain ambiguous. In this study, we investigated the effects of AA005 on human colon cancer cell lines in vivo.

Recombinant humanized anti-vascular endothelial growth factor monoclonal antibody efficiently suppresses laser-induced choroidal neovascularization in rhesus monkeys.

Neovascular age-related macular degeneration, characterized by abnormal choroidal neovascularization (CNV), is a major cause of blindness worldwide. Anti-vascular endothelial growth factor (VEGF) antibodies have demonstrated significant efficacy in improving visual acuity. TMAB001 is a new recombinant humanized rabbit anti-VEGF monoclonal antibody.

Angiotensin converting enzyme 2 is primarily epithelial and is developmentally regulated in the mouse lung.

Angiotensin converting enzyme (ACE) 2 is a carboxypeptidase that shares 42% amino acid homology with ACE. Little is known about the regulation or pattern of expression of ACE2 in the mouse lung, including its definitive cellular distribution or developmental changes. Based on Northern blot and RT-PCR data, we report two distinct transcripts of ACE2 in the mouse lung and kidney and describe a 5' exon 1a previously unidentified in the mouse.

Enhanced binding of Sp1/Sp3 transcription factors mediates the hyperoxia-induced increased expression of the lung type I cell gene T1alpha.

The transcription factor Sp1 plays an important regulatory role in transactivation of the lung type I cell differentiation gene T1alpha. Like other lung cells, type I cells may encounter changes in oxygen concentration during the lifetime of the organism. We found that exposure of mice to hyperoxia rapidly increases expression of T1alpha and other type I cell genes, and that returning the mice to normoxia quickly decreases expression.

T1alpha, a lung type I cell differentiation gene, is required for normal lung cell proliferation and alveolus formation at birth.

T1alpha, a differentiation gene of lung alveolar epithelial type I cells, is developmentally regulated and encodes an apical membrane protein of unknown function. Morphological differentiation of type I cells to form the air-blood barrier starts in the last few days of gestation and continues postnatally. Although T1alpha is expressed in the foregut endoderm before the lung buds, T1alpha mRNA and protein levels increase substantially in late fetuses when expression is restricted to alveolar type I cells.

The alpha-isoform of caveolin-1 is a marker of vasculogenesis in early lung development.

Caveolin-1 is a scaffolding protein component of caveolae, membrane invaginations involved in endocytosis, signal transduction, trans- and intracellular trafficking, and protein sorting. In adult lung, caveolae and caveolin-1 are present in alveolar endothelium and Type I epithelial cells but rarely in Type II cells. We have analyzed patterns of caveolin-1 expression during mouse lung development.

DANCE in developing and injured lung.

We identified rat developing arteries and neural crest derivatives with multiple epidermal growth factor-like domains (DANCE) as a developmentally regulated gene using suppression-subtractive hybridization. Northern analysis confirmed a fivefold induction of this mRNA transcript between fetal day 18 and 20 that persisted through postnatal day 17. The level was declining at postnatal day 21 and was similar in adult lung to that at fetal day 18.
