Dexmedetomidine Attenuates High Glucose-induced HK-2 Epithelial-mesenchymal Transition by Inhibiting AKT and ERK / 生物医学与环境科学（英文）

Objective@#To explore the protective effects of dexmedetomidine (Dex) against high glucose-induced epithelial-mesenchymal transition in HK-2 cells and relevant mechanisms.@*Methods@#HK-2 cells were exposed to either glucose or glucose+Dex for 6 h. The production of ROS, morphology of HK-2 cells, and cell cycle were detected. Moreover, the expression of AKT, p-AKT, ERK, p-ERK, PI3K, E-Cadherin, Claudin-1, and α-SMA were determined and compared between HK-2 cells exposed to glucose and those exposed to both glucose and Dex with or without PI3K/AKT pathway inhibitor LY294002 and ERK pathway inhibitor U0126.@*Results@#Compared with HK-2 cells exposed to high level of glucose, the HK-2 cells exposed to both high level of glucose and Dex showed: (1) lower level of ROS production; (2) cell morphology was complete; (3) more cells in G1 phase; (4) lower expression of p-AKT, p-ERK and α-SMA, higher expression of E-Cadherin and Claudin-1. PI3K/AKT inhibitor LY294002 and ERK inhibitor U0126 decreased the expression of p-AKT, p-ERK and α-SMA, and increased the expression of E-Cadherin and Claudin-1.@*Conclusion@#Dex can attenuate high glucose-induced HK-2 epithelial-mesenchymal transition by inhibiting AKT and ERK.

Effect of NRP1 gene knockout on process of radiationinduced pulmonary fibrosis and its mechanism / 吉林大学学报(医学版)

Objective: To observe the effect of neuroopilin-1 (NRP1) gene on the process of radiation-induced pulmonary fibrosis (RIPF), and to explore its roles in the occurrence and development of epithelial-mesenchymal transition (EMT) mediated by Wnt/fi-catenin pathway tail identification was performed in and TGF-β1/Smads pathway, and extracellular matrix (ECM) deposition. Methods: The Cre-LoxP recombinase system was used to construct the transgenic C57BL/6J mice with NRP1 gene specific knockout in alveolar type II epithelial cells (AT-II) and the mice. A total of 160 mice were randomly divided into 4-week group, 8-week group, 16-week group and 24-week group. In each group, the mice were randomly divided into wild type (Con) group, wild type+irradiation (IR) group, NRP1 gene-specific knockout (KO-Con) group, NRP1 gene-specific knockout+irradiation (KO+IR) group according to the method of random number table; there were 10 mice per group. In KO-Con and KO + IR groups, the NRP1 gene was specifically knocked out in the AT-II cells by intraperitoneal injection of tamoxifen, and the mouse models of RTPF were established by 20 Gy total thoracic irradiation in IR group and KO+IR group. After the models were constructed, HE staining and Masson staining were used to verify whether the models were successfully constructed. Immunohistochemistry (IHC) method was used to detect the type I collagen (Col I) and crsmooth muscle actin α-SMA) protein expression levels; Western blotting method was performed to detect the NRP1, β-catenin, TGF-β1, and Smad2 protein expression levels in the lung tissue of the mice; Quantitative fluorensence real-time polymerase chain reaction (qRT-PCR) method was used to detect the expression levels of NRP1, Col I, α-SMA, β-catenin, TGF-βl, Smad2, E-cadherin, N-cadherin, and Vimentin mRNA in the lung tissue of the mice. Results: The results of HE and Masson staining showed the RTPF models were successfully established, and the lung tissue of the mice in IR group mainly showed the pathomorphology of radiation pneumonitis. Compared with Con group, the protein and mRNA expression levels of NRP1 in the lung tissue of the mice in IR group were gradually increased with the prolongation of time (P<0.05), and reached the highest at 24 weeks (P<0.01). Compared with Con group, the expression levels of Col I, α-SMA, β-catenin, TGF-β1, and Smad2 proteins and mRNA in the lung tissue of the mice in IR group and KO+IR group were increased gradually with the prolongation of time (P<0.05 or P<0.01). Compared with IR group, the expression levels of Col I, α-SMA, β-catenin, TGF-β1, and Smad2 protein and mRNA in the lung tissue of the mice in KO+IR group were significantly decreased (P<0.05 or P<0.01), but they were higher than those in Con group (P<0.05 or P<0.01). Compared with Con group, the expression levels of the epithelial cell marker E-Cadherin mRNA in the lung tissue of the mice in IR group and KO+IR group were gradually decreased with the prolongation of time (P< 0.01), and the expression levels of the interstitial cell markers N-Cadherin and Vimentin were increased (P<0.05 or P<0.01), but the expression levels of E-cadhern mRNA in the lung tissue of the mice in KO-IR group were significantly higher than those in IR group (P<0.05 or P<0.01), and the expression levels of N-Cadherin and Vimentin mRNA in the lung tissue of the mice in KO + IR group at each time point were lower than those in IR group (P<0.05 or P<0.01). Conclusion: Knockout of NRP1 gene can inhibit the occurrence and development of RTPF, and its mechanism may be involved in regulating the expressions of Wnt/fi-catenin and TGF-β1/Smads signaling pathways in the lung tissue and inhibiting the EMT process in the mice.

Evaluation on safety of puerarin injection in clinical use / 中国中药杂志

Puerarin injection is commonly used in clinical treatment of coronary heart disease, angina pectoris, retinal artery, vein occlusion, sudden deafness and so on. This paper is aimed to evaluate the safety of puerarin injection in clinical use and explore the related factors that may cause its adverse reactions (ADRs), so as to find the warning signal of safety medication in time, put forward early warning, make early judgment and treatment, and ensure the safety of drug use. By strengthening surveillance, the best medication plan was established to prevent the occurrence of adverse reactions of puerarin injection and enhance people's awareness on the safety of puerarin injection. Database were searched to collect literature related to ADRs of puerarin injection. The data were extracted and analyzed by decision tree with treeage software and ² test was used to verify the data. A total of 62 papers involving 129 cases were included. The results showed that ADRs occurred mostly in patients aged 50-79 years, with the immune system and blood system accounting for the majority (88.3%), and ADRs occurred mostly 48 h after drug administration (61.1%). The severity of ADRs was not related to the dosage of puerarin, but it was related to the choice of the infusion solvent. In puerarin injection, most of the ADRs were moderate or severe (64.3%), 13 out of 129 cases were of death. Therefore, the indications and methods of use should be strictly controlled, and the allergic history of patients should be carefully questioned before medication to strengthen the monitoring of drug use.

A new classification of duplex kidney based on kidney morphology and management / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The initial classic classification of duplex kidney into complete (two ureters) and incomplete ("Y" shaped ureter) types are based on the ureter status. At the meantime, the features of the upper and lower moieties of duplex kidney were very crucial for appropriate procedure of hemi-nephrectomy, which was most commonly used for addressing the issues caused by a duplex kidney; and recently more applications of laparoscopy were used. In this study, we aimed prudently to propose a new classification based on the features of the upper and lower moieties of duplex kidney.</p><p><b>METHODS</b>Sixty-five children with 83 duplex kidneys were reviewed retrospectively. Based on kidney morphology found in CT urography and surgical findings, duplex kidney was classified into five types.</p><p><b>RESULTS</b>The first was the appendant type (36/83) and its feature was that the mini upper moiety was located on top of the lower one, with a visualized shallow groove between them. The ureter was dilated with an ectopic orifice or ureterocele. The second was the embedded type (13/83), the feature of which was that mini upper moiety located in the interior top of the lower one within the same capsule. The upper ureter was dilated with an ectopic orifice or ureterocele. The third was the hydronephrosis type (12/83). The severe hydronephrotic upper moiety was almost as big as the lower moiety. The upper ureter was severely dilated and circuitous with an ectopic orifice. The forth was the dual-poor type (2/83). The two moieties were all very small with "Y" shaped ureters and ectopic orifices. The last was the dual-well type (20/83). The upper moiety was almost the same size as the lower one, without apparent dilation of "Y" shaped or double ureters.</p><p><b>CONCLUSION</b>Based on kidney morphology, duplex kidney can be mainly classified into five types which can be depicted by CT urography prior to management and can provide an aid in selecting a successful course of surgical correction.</p>
