Liver diseases cannot be easily detected in the early stage, and although invasive diagnostic methods, such as liver biopsy, are relatively accurate, they tend to have a low degree of acceptance, which greatly limits the improvement in diagnosis and treatment techniques for liver diseases. Therefore, it is of great importance to search for new biomarkers and therapeutic targets. As an emerging biomarker for liquid biopsy, tRNA-derived small RNA (tsRNA) is abnormally expressed in various liver diseases including viral hepatitis, fatty liver disease, liver injury, and liver cancer, and it can affect the development and progression of liver diseases by regulating the biological functions such as gene expression, epigenetic regulation, and protein translation. This article reviews the origin, classification, and biological function of tsRNA, as well as the research advances in tsRNA as biomarkers and potential therapeutic targets for liver diseases, so as to provide ideas for the early diagnosis and treatment of liver diseases.

OBJECTIVE:
To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery.
METHODS:
Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups.
RESULTS:
The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05).
CONCLUSION
Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.

Objective:To investigate the impact of different ventilation modalities during initial resuscitation on short-term outcomes in adult patients with in-hospital cardiac arrest (IHCA).Methods:This retrospective study included adult patients (age ≥18 years) admitted to the emergency resuscitation or observation units of our hospital from September 2019 to December 2021. Demographic data, comorbidities, and short-term outcomes of IHCA patients who underwent airway management during resuscitation were recorded. Participants were stratified into non-advanced airway and advanced airway groups based on ventilation modality. The primary outcome was defined as sustained return of spontaneous circulation (ROSC) ≥20 min, and secondary outcomes included survival to discharge and favorable neurological status at discharge. Logistic regression analyses were performed to assess the impact of different ventilation modalities on short-term outcomes among adult IHCA patients. and developed a prediction model of ROSC for adult IHCA patients, and its predictive performance was evaluated by the area under the curve (AUC) of the receiver operating characteristic.Results:Among 285 IHCA patients (non-advanced airway: n=75; advanced airway: n=210), 127 achieved ROSC ≥20 min, 51 survived to discharge, and 35 had favorable neurological outcomes. Logistic regression identified ventilation modality, epinephrine dose, and arrest location as independent predictors of ROSC in adult IHCA patients. Advanced airway management demonstrated significantly higher ROSC rates compared to non-advanced interventions ( OR=3.698, 95% CI:1.844-7.419, P<0.001). However, no significant associations were observed between ventilation modalities and survival to discharge ( OR=1.097, 95% CI:0.506-2.376, P=0.815) or favorable neurological outcomes at discharge ( OR=0.548, 95% CI:0.224-1.339, P=0.187). Ventilation modality, epinephrine dose, and arrest location were incorporated as predictors in a multivariable logistic regression model to develop a ROSC prediction model for adult IHCA patients. The discriminative ability of model was evaluated through receiver operating characteristic (ROC) curve analysis, yielding an AUC of 0.735 (95% CI:0.678-0.793). Subgroup analyses demonstrated that early advanced airway management significantly enhanced ROSC rates in noncardiac etiology cases, whereas no such benefit was observed in cardiac etiology cases, while this intervention correlated with decreased survival to discharge rates and deteriorated neurological outcomes among survivors. Conclusions:Advanced airway management demonstrated improved ROSC rates in adult IHCA cases, while showing no significant improvement in survival rates or favorable neurological outcomes at discharge. Ventilation modality, epinephrine dose, and arrest location are independent predictors of ROSC. A model integrating these factors exhibits moderate predictive utility for IHCA outcomes.

Objective:To explore the influencing factors of clinical pregnancy outcomes in patients with hydrosalpinx undergoing in vitro fertilization-embryo transfer(IVF-ET) after interventional embolization and whether residual hydrops has an adverse impact on pregnancy outcomes.Methods:Clinical data from 65 patients who underwent interventional embolization and IVF-ET for hydrosalpinx at the Third Affiliated Hospital of Zhengzhou University from March 2021 to October 2022 were collected retrospectively. The hydrops index was quantified by the ratio of the widest diameter to the pelvic transverse diameter of the intraoperative hydrops, and the patient′s age, body mass index(BMI), follicle-stimulating hormone(FSH), lutenizing hormine(LH), estradiol(E2), automated matetials hangling(AMH), endometrial thickness at the time of transplantation, the number of transplanted embryos, embryo type, and location of the hydrosalpinx were recorded. In addition, the clinical pregnancy outcomes of the first transplantation after embolization were followed. Two independent samples t-test, rank sum test and chi-square test were used to analyze the difference of the above indexes among different clinical pregnancy outcomes by SPSS 25.0. The receiver operating characteristic (ROC) curves and Youden index were used to calculate the cut-off value of the water accumulation index. Results:Among 65 patients, the clinical pregnancy rate was 63.1%(41/65), among the 45 patients who underwent embryo transfer before embolization without success, the clinical pregnancy rate after embolization was 62.2%(28/45). Based on data analysis, it showed that IVF-ET clinical pregnancy outcomes were not associated with age, BMI, FSH, LH, E2, AMH, endometrial thickness at the time of transplantation, the number of transplanted embryos, embryo type, as well as location of hydrosalpinx( P>0.05), but associated with hydrosalpinx index( P<0.001). ROC curve analysis showed that the hydrops index could be used as a predictor of pregnancy outcome, and the area under the curve was 0.825, and the optimal cut-off value of the hydrops index was 12.925% based on the Youden index analysis result. Conclusions:Interventional embolization of hydrosalpinx may improve clinical pregnancy rates. When the hydrosalpinx is large enough, it could adversely affected IVF-ET clinical pregnancy, and further aspiration of hydrosalpinx should be performed prior to transplantation.
