[Mongolian medicine Naru-3 reduces neuroinflammation in maintenance stage of neuropathic pain by inhibiting astrocyte activation].

Neuropathic pain(NP) is difficult to be treated since it has similar phenotypes but different pathogenesis in different pathological stages. Targeted intervention of the core regulatory elements at different pathological stages of NP has become a new direction of drug research and development in recent years and provides the possibility for the treatment of NP. The Mongolian medicine Naru-3(NR-3) is effective in the treatment of sciatica and trigeminal neuralgia, the mechanisms of which remain unknown.

[Mechanism of Mongolian drug Naru-3 in initiation of neuroinflammation of neuropathic pain from MMP9/IL-1β signaling pathway].

Neuropathic pain(NP) has similar phenotypes but different sequential neuroinflammatory mechanisms in the pathological process. It is of great significance to inhibit the initiation of neuroinflammation, which has become a new direction of NP treatment and drug development in recent years. Mongolian drug Naru-3 is clinically effective in the treatment of trigeminal neuralgia, sciatica, and other NPs in a short time, but its pharmacodynamic characteristics and mechanism of analgesia are still unclear.

Long-term observation after transplantation of cultured human corneal endothelial cells for corneal endothelial dysfunction.

Background: Corneal transplantation is the only way to treat serious corneal diseases caused by corneal endothelial dysfunction. However, the shortage of donor corneal tissues and human corneal endothelial cells (HCECs) remains a worldwide challenge. We cultivated HCECs by the use of a conditioned medium from orbital adipose-derived stem cells (OASC-CM) in vitro.

[Effects of organic fertilizer application on crop yield and soil properties in rice-wheat rotation system: A meta-analysis].

To clarify the effects of organic fertilizer application on crop yield and soil properties in rice-wheat rotation system in China, we carried out a meta-analysis to quantitatively evaluate the effects of organic fertilizer types (ordinary organic fertilizer, biochar, and straw), fertilization regimes (organic fertilizer alone, organic fertilizer + partial chemical fertilizer, and organic fertilizer + full amount of chemical fertilizer), and experiment duration (short term, medium term, and long term) on soil properties and the yield of rice and wheat, as well as their responses to soil conditions (acid, neutral, basic). Results showed that the application of organic fertilizer had similar yield-increase effect on rice yield (3.1%) and wheat yield (3.

Bioinformatics analysis of key biomarkers for retinoblastoma.

Objective: To identify key genes involved in occurrence and development of retinoblastoma.

Methods: The microarray dataset, GSE5222, was downloaded from the gene expression omnibus (GEO) database. Differentially expressed genes (DEGs) between unilateral and bilateral retinoblastoma were identified and functional enrichment analysis performed.

miR‑15a‑3p affects the proliferation, migration and apoptosis of lens epithelial cells.

The present study investigated the effect of microRNA (miR)‑15a‑3p on the proliferation, migration and apoptosis of lens epithelial cells and its potential mechanism, in order to further elucidate the pathogenesis of age‑related cataracts (ARCs). The HLE‑B3 human lens epithelial cell line was transfected with miR‑15a‑3p mimic. Expression of the miR‑15a‑3p mimic was measured by fluorescence‑based reverse transcription‑quantitative polymerase chain reaction analysis.

[TCM Combined Western Medicine Treatment of Advanced NSCLC: a Preliminary Study of mIRNA Expression Profiles].

Objective To preliminarily observe miRNA gene profiles in benefit serum of advanced non-small cell lung cancer (NSCLC) treated by TCM combined Western medicine (WM) , and to seek for molecular markers for its efficacy monitoring and prediction. Methods Recruited were 5 advanced NSCLC patients who received TCM combined WM treatment and obtained efficacy benefit ( as the treatment group) , 3 advanced NSCLC patients who received early treatment ( as the lung cancer group) , and 3 healthy subjects (as the control group). Serum samples were collected and total RNA was extracted using Trizol method.

Oxidized low-density lipoprotein attenuated desmoglein 1 and desmocollin 2 expression via LOX-1/Ca(2+)/PKC-β signal in human umbilical vein endothelial cells.

Numerous studies have reported the presence of oxidized LDL (ox-LDL) and expression of its lectin-like receptor, LOX-1, have been shown in atherosclerotic regions. The present study aims to investigate the effects of ox-LDL on expression of desmoglein 1 (DSG1) and desmocollin 2 (DSC2) in endothelial cells, and to explore the role of LOX-1 mediated signal in the permeability injury associated with DSG1 and DSC2 disruption induced by oxidized lipoprotein. RT-PCR and Western blotting were applied to determine the mRNA and protein expression levels of DSG1 and DSC2 in human umbilical vein endothelial cells (HUVECs) respectively.

[Study on oligosaccharides from Morinda officinalis].

Objective: To study the oligosaccharides from Morinda officinalis How.

Methods: Compounds were isolated by chromatography, and their structures were identified by spectral analysis and chemical evidences.

Results: Six compounds were isolated and identified as sucrose (I), inulin-type trisaccharide (II), inulin-type hexasaccharide (III), inulotriose (IV), inulotetraose (V), inulopentaose (VI).

An involvement of SR-B1 mediated PI3K-Akt-eNOS signaling in HDL-induced cyclooxygenase 2 expression and prostacyclin production in endothelial cells.

It is well-known that sphingosine-1-phosphate (S1P), the phospholipid content of HDL, binding to S1P receptors can raise COX-2 expression and PGI(2) release through p38MAPK/CREB pathway. In the present study we assess the action of SR-B1 initiated PI3K-Akt-eNOS signaling in the regulation of COX-2 expression and PGI(2) production in response to HDL. We found that apoA1 could increase PGI(2) release and COX-2 expression in ECV 304 endothelial cells.

[A clinical study on gestational transient thyrotoxicosis].

Objective: To investigate the prevalence of gestational transient thyrotoxicosis (GTT) and analyze the cause of thyrotoxicosis encountered in this period.

Methods: An epidemiologic survey in ten hospitals in Shenyang was performed and 534 pregnant women during the first trimester of pregnancy filled questionnaire, received physical examination and had serum thyroid-stimulating hormone (TSH), free T(4) (FT(4)), free T(3) (FT(3)), thyroid peroxidase antibody (TPOAb), thyrotrophin receptor antibody (TRAb), and human chorionic gonadotrophin (hCG) tests.

Results: (1) The total prevalence of thyrotoxicosis was 9.
