Liver transplantation is an effective treatment of end-stage liver diseases. However, liver ischemia-reperfusion injury (IRI) and rejection significantly cause the decrease of survival rate of liver graft. Therefore, it is urgent to explore a novel method, which can not only alleviate liver IRI, but also promote immune tolerance of allograft, thereby improving the survival rate of liver graft. Extracellular vesicle (EV) is nanoparticle released from cells into the extracellular microenvironment, which may alleviate graft injury by repairing autophagy, immunosuppression and accelerating tissue regeneration. Hence, EV becomes a research hot spot in the field of liver transplantation. Nevertheless, the clinical application of EV encounters multiple challenges, such as separation, purification, identification, storage of EV and how to deliver EV to the target cells. In this article, the mechanism of EV in liver IRI, the challenges in clinical application of EV and the potential application of EV were reviewed, aiming to provide reference for the clinical application of EV in liver transplantation.

Objective To evaluate the effect and mechanism of nicotinamide mononucleotide (NMN) on ischemia-reperfusion injury (IRI) induced by donor liver after cardiac death in rat models. Methods Rat models of orthotopic liver transplantation were established by "magnetic ring + double cuff" method. SD rats were randomly divided into the sham operation group (Sham group), orthotopic liver transplantation group (OLT group), NMN treatment + orthotopic liver transplantation group (NMN group), NMN+sirtuin-3 (Sirt3) inhibitor (3-TYP) + orthotopic liver transplantation group (NMN+3-TYP group), respectively. Pathological changes and hepatocyte apoptosis of the rats were observed in each group. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were determined. Superoxide dismutase (SOD) and malondialdehyde (MDA) contents in liver tissues were detected. The expression levels of Sirt3, microtubule-associated protein 1 light chain 3 (LC3)Ⅱ, PTEN-induced putative kinase 1 (PINK1), Parkin and translocase of the outer mitochondrial membrane 20 (TOMM20) in liver tissues were measured. Postoperative survival of the rats in each group was analyzed. Results Compared with the Sham group, serum ALT and AST levels were higher in the OLT group. Compared with the OLT group, the levels of ALT and AST were decreased in the NMN group. Compared with the NMN group, the levels of ALT and AST were increased in the NMN +3-TYP group (all

Objective:To explore the effect of health education based on theory of planned behavior combined with stepped care model on negative emotion, psychological flexibility and quality of life in patients with lung cancer undergoing chemotherapy.Methods:From October 2020 to December 2021, 108 chemotherapy patients who underwent lung cancer surgery in Affiliated Hospital of Weifang Medical College and had anxiety or depression that scores was greater than 7 in any dimension of the Hospital Anxiety and Depression Scale (HADS) were selected as the study subjects. The study subjects were divided into observation group ( n=46) and control group ( n=48) by random digits table method. Routine care was implemented in the control group. The observation group implemented health education based on the theory of planned behavior combined with stepped care model intervention. The HADS scale was used every 4 weeks to assess negative emotion in both groups. In observation, patients with negative emotion relief stop the next stage of nursing intervention, and patients without relief continue the next stage of higher intensity nursing intervention. Results:Before the intervention, there were no significant difference in the scores of negative emotion, psychological flexibility and quality of life between the two groups ( P>0.05). After intervention, the scores of all dimensions of negative emotion and the total score in the observation group were significantly lower than those in the control group, and the differences had statistical significance ( t=4.86, 3.19 and 4.53, all P<0.05). After the intervention the scores of psychological flexibility and quality of life dimensions and the total score in the observation group were higher than those in the control group, the differences had statistical significance (t values were -6.01--2.89, all P<0.05). After the intervention, there was no significant difference in the remission rate of negative emotions between the clinical observation stage of the observation group and the concurrent control group ( P>0.05). The remission rates of guided self-help, problem-solving therapy, psychological or drug therapy and total negative emotions in the observation group were 38.46%(15/39), 33.33%(8/24), 6/16 and 78.26%(36/46), respectively, which were higher than those in the control group, and the differences had statistical significance ( χ2 values were 7.04 - 13.80, all P<0.05). Conclusions:Health education based on the theory of planned behavior combined with stepped care model can effectively alleviate the negative emotions of lung cancer patients undergoing chemotherapy and improve psychological flexibility and quality of life.

Cachexia is a common complication in patients with lung cancer. It aggravates the toxic and side effects of chemotherapy, hinders the treatment plan, weakens the responsiveness of chemotherapy, reduces the quality of life, increases complications and mortality, and seriously endangers the physical and mental health of patients with lung cancer. The causes and pathogenesis of tumor cachexia are extremely complex, which makes its treatment difficult and complex. Controlling cachexia in lung cancer patients requires many means such as anti-tumor therapy, inhibition of inflammatory response, nutritional support, physical exercise, and relief of symptoms to exert the synergistic effect of multimodal therapy against multiple mechanisms of tumor cachexia. To date, there has been a consensus within the discipline that no single therapy can control the development of cachexia. Some therapies have made some progress, but they need to be implemented in combination with multimodal therapy after fully assessing the individual characteristics of lung cancer patients. This article reviews the application of drug therapy and nutritional support in lung cancer patients, and looks forward to the research direction of cachexia control in lung cancer patients.

Objective:
To investigate the value of tumor perfusion parameter measured by using double contrast-enhanced ultrasound (DCEUS) QontraXt three-dimensional pseudocolor quantitative analysis to the therapeutic effect evaluation of preoperative neoadjuvant chemotherapy (NAC) in advanced gastric cancer (AGC) patients.
Methods:
Eighty-nine AGC patients underwent 3 cycles of preoperative NAC (XELOX) followed by complete resection of lesion. The DCEUS QontraXt three-dimensional pseudocolor was performed one or two weeks before the NAC and operation were applied, respectively. The peak enhancement (PE), time to peak (TP), sharpness of the bolus (β) and area under the enhancement curve (AUC) of primary gastric tumor were measured by QontraXt three-dimensional pseudocolor quantitative analysis. These DCEUS parameters between respond and non-respond groups before and after NAC therapy were compared. The prediction accuracy of DCEUS to the therapeutic effect evaluation of preoperative NAC was determined by the receive operating characteristic (ROC) curves.
Results:
Among 89 AGC patients, 52 patients responded to NAC therapy, while 37 patients resisted to NAC therapy. Twelve cases in respond group and 26 cases in non-respond group were mucinous carcinoma. Forty cases in respond group and 11 cases in non-respond group were non-mucinous carcinoma (
