Interaction between ischemia-reperfusion injury and intestinal microecology in organ transplantation and its therapeutic prospects.

Organ transplantation is a vital intervention for end-stage organ failure; however, ischemia-reperfusion injury is a complication of transplantation, affecting the prognosis and survival of transplant recipients. As a complex ecosystem, recent research has highlighted the role of the intestinal microecology in transplantation, revealing its significant interplay with ischemia-reperfusion injury. This review explores the interaction between ischemia-reperfusion injury and intestinal microecology, with a special focus on how ischemia-reperfusion injury affects intestinal microecology and how these microecological changes contribute to complications after organ transplantation, such as infection and rejection.

The Tailored Material Removal Distribution on Polyimide Membrane Can Be Obtained by Introducing Additional Electrodes.

Reactive ion etching (RIE) is a promising material removal method for processing membrane diffractive optical elements and fabrication of meter-scale aperture optical substrates because of its high-efficiency parallel processing and low surface damage. However, the non-uniformity of the etching rate in the existing RIE technology will obviously reduce the machining accuracy of diffractive elements, deteriorate the diffraction efficiency and weaken the surface convergence rate of optical substrates. In the etching process of the polyimide (PI) membrane, additional electrodes were introduced for the first time to achieve the modulation of the plasma sheath properties on the same spatial surface, thus changing the etch rate distribution.

Disease prediction based on multi-type data fusion from Chinese electronic health record.

Disease prediction by using a variety of healthcare data to assist doctors in disease diagnosis is becoming a more and more important research topic recently. This paper proposes a disease prediction model that fuses multiple types of encoded representations of Chinese electronic health records (EHRs). The model framework utilizes a multi-head self-attention mechanism, which combines textual and numerical features to enhance text representations.

Numerical Study on Entropy Generation of the Multi-Stage Centrifugal Pump.

The energy loss of the multi-stage centrifugal pump was investigated by numerical analysis using the entropy generation method with the RNG k-ε turbulence model. Entropy generation due to time-averaged motion and velocity fluctuation was mainly considered. It was found that the entropy generation of guide vanes and impellers account for 71.

[Transhepatic arterial chemoembolization with gemcitabine and carboplatin for the treatment of stage III hepatocellular carcinoma].

Objective: To evaluate the efficiency and safety of transhepatic arterial chemoembolization (TACE) with gemcitabine and carboplatin for the treatment of stage III hepatocellular carcinoma (HCC).

Methods: Sixty-one HCC patients were treated by TACE. During TACE, At first, intra-arterial infusion of carboplatin 300 mg/m2, then gemcitabine 1000 mg/m2 with 5-30 ml of ultra-lipoidal iodide oil emulsion was used for arterial embolization.

Association between vascular endothelial growth factor and metastasis after transcatheter arterial chemoembolization in patients with hepatocellular carcinoma.

Background: Hypoxia up-regulates vascular endothelial growth factor (VEGF) and stimulates the growth of hepatocellular carcinoma (HCC) cells. This study was designed to investigate the association between changes in plasma VEGF levels after transcatheter arterial chemoembolization (TACE) and HCC progression, especially in relation to metastasis.

Methods: Plasma VEGF levels were measured by quantitative sandwich enzyme-linked immunosorbent assay (ELISA R&D system).

[Relation between vascular endothelial growth factor and reoccurence-metastasis after transcatheter arterial chemoembolization in hepatocellar carcinoma].

Objective: To investigate the relation between changes in serum vascular endothelial growth factor (VEGF) level after transcatheter arterial chemoembolization (TACE) and hepatocellular carcinoma (HCC) progression, especially in relation to metastasis.

Methods: Serum VEGF expression level, measured by quatitative sandwich enzyme-linked immunosorbent assay (ELISA, R&D system), was measured before, 3 days and 4 weeks after TACE in 30 patients with HCC. The development of metastasis was evaluated at the end of the third month after TACE.

[Acute respiratory tract obstruction during thyroid operation: analysis of 10 cases].

Objective: To explore the causes and management of acute respiratory tract obstruction in patients undergoing thyroid operation.

Methods: A retrospective review was conducted in 10 such cases that we encountered in our 11 years' experience with thyroid operation.

Results: Respiratory tract obstructions occurred in 10(0.
