[Root morphological changes in maize and soybean intercropping system under different phosphorus levels].

A pot experiment was conducted to investigate the changes of root morphology and its relationship with P uptake under different P levels (0, 50 and 100 mg PO·kg, represented by P, P and P, respectively). The results showed that intercropping significantly changed root morphological parameters of both maize and soybean, and increased the root:shoot ratio in soybean under different P levels. Intercropping significantly increased root length, root surface area, root volume, and root dry weight of maize and soybean by 25.

[Effects of Regulating Smad7 Gene on Epithelial-Mesenchymal Transition in Keloid Keratinocyte].

Objective: The effect of Smad7 on epithelial-Mesenchymal Transition (EMT) of keloid keratinocytes was studied.

Methods: Culture formed keloid cutin cells (KK) and normal skin cutin cell (NK cells), built the Smad7 too slow virus slow virus vector and Smad7 interference expression vector, screening the best expression and interfering with the slow virus infection NK and KK cells respectively, and contrast carrier puro screening stable expression cell lines, stem cells can be divided into 8 groups: NK-Control (normal training of NK cells); NK-NC (NK cells screened against lentivirus); NK-shSmad7 (NK cells that interfere with lentivirus screening); NK-mSmad7 (NK cells screened for overexpression of lentivirus); KK-control (normal cultured KK cells); KK-NC (KK cells screened against lentivirus); KK-shSmad7 (KK cells that interfere with lentivirus screening); KK-mSmad7 (KK cells screened for overexpression of lentivirus). Cell proliferation was observed by the CCK-8 method, cell apoptosis was detected by flow cytometry, cell migration ability was detected by Transwell chamber, and expression of key proteins (N-cadherin and Occludin) in epithelium-interstitial transform was detected by Western blot.

A Network Meta-Analysis of Short and Long-Term Efficacy of Targeted Therapy With Single or Double-Drug Regimens in the Treatment of Stage III/IV Malignant Melanoma Based on 16 Randomized Controlled Trials.

For the treatment of stage III/IV malignant melanoma (MM), a network meta-analysis (NMA) was conducted to compare the short and long-term efficacy of targeted therapy with single or double-drug regimens. All conducted randomized controlled trials (RCTs) searched from PubMed and Cochrane Library were included in the study for direct and indirect comparison for MM. The odds ratio (OR) and surface under the cumulative ranking curves (SUCRA) value of the targeted therapy with single or double-drug regimens for treatment of stage III/IV MM were also analyzed.

[Different mechanisms mediated the potentiation uterine smooth muscle caused by Polygala tenuifolia decoction progesterone in virginal rats].

Objective: To research the effects of Polygala tenuifolia decoction on myoelectric activity of uterine smooth muscle and contractile activity of uterine smooth muscle strips of virginal rats.

Method: To record the effects of P. tenuifolia decoction on myoelectric activity of uterine smooth muscle and contractile activity of uterine smooth muscle strips of virginal rats with biolap 410 biological system.
