Pig-to-human kidney xenotransplants using genetically modified minipigs.

This study develops an observational model to assess kidney function recovery and xenogeneic immune responses in kidney xenotransplants, focusing on gene editing and immunosuppression. Two brain-dead patients undergo single kidney xenotransplantation, with kidneys donated by minipigs genetically modified to include triple-gene knockouts (GGTA1, β4GalNT2, CMAH) and human gene transfers (hCD55 or hCD55/hTBM). Renal xenograft functions are fully restored; however, immunosuppression without CD40-CD154 pathway blockade is ineffective in preventing acute rejection by day 12.

Regional anesthesia might reduce recurrence and metastasis rates in adult patients with cancers after surgery: a meta-analysis.

Background: The influence of anesthesia techniques on cancer recurrence and metastasis following oncological surgery is a topic of growing interest. This meta-analysis investigates the potential effects of regional anesthesia (RA), either independently or combined with general anesthesia (GA), on these outcomes.

Methods: We performed an extensive search across PubMed, Embase, and the Cochrane Library databases.

Comparison of bispectral index and patient state index as measures of sedation depth during surgeries using remimazolam tosilate.

Background: The Bispectral Index (BIS) and the Patient State Index (PSI) are commonly used measures to assess intraoperative sedation depth. However, model differences lead to different results, which in turn interferes with clinicians' judgment on the depth of anesthesia. Remimazolam tosilate (RT) for injection is a new benzodiazepine used in sedation.

FraudAuditor: A Visual Analytics Approach for Collusive Fraud in Health Insurance.

Collusive fraud, in which multiple fraudsters collude to defraud health insurance funds, threatens the operation of the healthcare system. However, existing statistical and machine learning-based methods have limited ability to detect fraud in the scenario of health insurance due to the high similarity of fraudulent behaviors to normal medical visits and the lack of labeled data. To ensure the accuracy of the detection results, expert knowledge needs to be integrated with the fraud detection process.

Evaluation of the reliability of the upper lip bite test and the modified mallampati test in predicting difficult intubation under direct laryngoscopy in apparently normal patients: a prospective observational clinical study.

Here, we intend to determine diagnosis-valuable biomarkers for PAH and decode the fundamental mechanisms of the biological function of these markers. Two mRNA microarray profiles (GSE70456 and GSE117261) and two microRNA microarray profiles (GSE55427 and GSE67597) were mined from the Gene Expression Omnibus platform.

Identification of novel biomarkers involved in pulmonary arterial hypertension based on multiple-microarray analysis.

Pulmonary arterial hypertension (PAH) is a life-threatening chronic cardiopulmonary disorder. However, studies providing PAH-related gene expression profiles are scarce. To identify hub genes involved in PAH, we investigate two microarray data sets from gene expression omnibus (GEO).

Protective effect of Hydroxysafflor Yellow A on cerebral ischemia reperfusion-injury by regulating GSK3β-mediated pathways.

Ischemia-reperfusion (I/R) injury is accompanied by high mortality and morbidity. Unfortunately, there are few effective therapeutic medicines and strategies to enhance its outcome. Hydroxysafflor Yellow A (HSYA) exerts multiple biological activities and has potential protective effects against I/R injury in the brain, liver and heart.

Protective Effects of Nicorandil on Cardiac Function and Left Ventricular Remodeling in a Rat Model of Ischemic Heart Failure.

Nicorandil, the first clinically applied ATP-sensitive K channel (KATP) opener with nitrate property, has demonstrated cardioprotective effects in patients with multiples of heart diseases. However, it is unknown whether nicorandil has effects on left ventricular (LV) remodeling in rats with ischemic heart failure and the potential mechanisms remain unclear. In this study, we investigated the effects of nicorandil on cardiac function, LV remodeling, and Bax expression in myocardium of LV in rats with ischemic heart failure.

Dexmedetomidine reduces ventilator-induced lung injury (VILI) by inhibiting Toll-like receptor 4 (TLR4)/nuclear factor (NF)-κB signaling pathway.

Mechanical ventilation (MV) may lead to ventilator-induced lung injury (VILI). Previous research has shown that dexmedetomidine attenuates pulmonary inflammation caused by MV, but the underlying mechanisms remain unclear. Our study aims to test whether dexmedetomidine has a protective effect against VILI and to explore the possible molecular mechanisms using the rat model.

The protective effect of dopamine on ventilator-induced lung injury via the inhibition of NLRP3 inflammasome.

Dopamine (DA), a neurotransmitter, was previously shown to have anti-inflammatory effects. However, its role in ventilator-induced lung injury (VILI) has not been explicitly demonstrated. This study aimed to investigate the therapeutic efficacy and molecular mechanisms of dopamine in VILI.

The Effects of Two Anesthetics, Propofol and Sevoflurane, on Liver Ischemia/Reperfusion Injury.

Background: Propofol and sevoflurane are widely used in clinical anesthesia, and both have been reported to exert a protective effect in organ ischemia/reperfusion (IR). This study aims to investigate and compare the effects of propofol and sevoflurane on liver ischemia/reperfusion and the precise molecular mechanism.

Methods And Materials: Rats were randomized into four groups: the sham group, I/R group, propofol treatment group (infused with 1% propofol at 500 μg· kg-1· min-1), and sevoflurane treatment group (infused with 3% (2 L/min) sevoflurane).

Scutellarin protects cardiomyocyte ischemia-reperfusion injury by reducing apoptosis and oxidative stress.

Aims: Ischemic heart disease is a leading cause of death and disability worldwide. Despite recent advances, there is no effective therapy for preventing myocardial ischemia-reperfusion (I/R) injury. In this study, we aimed to examine the therapeutic effect of scutellarin, a flavone isolated from the traditional Chinese medicine Scutellaria barbata and Erigeron breviscapus, on cardiomyocyte I/R injury.

Undiagnosed giant cystic pheochromocytoma: A case report.

Giant cystic pheochromocytomas (GPCCs) are rare adrenal tumors and the majority of them present as asymptomatic. As a result GPCCs often remain undiagnosed until surgery and therefore the surgical team face a greater challenge in perioperative management. The present study describes the case of a 36 year-old woman with an undiagnosed GPCC, which was successfully resected despite the occurrence of perioperative cardiovascular events, including hypertension, hypotension, ventricular arrhythmias, acute heart failure, acute myocardial infarction, and the patient was discharged home without any recurrence.

Intraoperative intravenous lidocaine exerts a protective effect on cell-mediated immunity in patients undergoing radical hysterectomy.

Surgical procedures cause a decrease in lymphocyte proliferation rate, an increase in apoptosis and shifts the balance of T‑helper (Th)1/Th2 cells towards anti‑cell‑mediated immunity (CMI) Th2 dominance, which is relevant to the immunosuppressive effects of CMI, postoperative septic complications and the formation of tumor metastasis. Previous studies have revealed that lidocaine exhibits antibacterial actions; regulating inflammatory responses, reducing postoperative pain and affecting the duration spent in hospital. Thus, the present study hypothesized that lidocaine may exert a protective effect on the CMI of patients undergoing surgery for the removal of a primary tumor.

Doxapram hastens the recovery following total intravenous anesthesia with dexmedetomidine, propofol and remifentanil.

Dexmedetomidine is a suitable sedative for awake fiberoptic intubation in patients with obstructive sleep apnea (OSA). However, previous studies have shown that dexmedetomidine delays recovery from propofol-remifentanil anesthesia. This study aimed to determine whether doxapram may hasten the recovery following dexmedotomidine-propofol-remifentanil anesthesia.

Intraoperative systemic lidocaine inhibits the expression of HMGB1 in patients undergoing radical hysterectomy.

Surgery stressors trigger inflammatory response and excessive inflammatory response leads to organ failure or even septic shock. HMGB1 as a later inflammatory cytokines and a critical mediator of severe sepsis is always associated with the aggravation of organ failure. Previous study shows that lidocaine can inhibit the expression of HMGB1 in macrophage of septic rats and protect animals from organ failure.

Suppression of inflammatory response by flurbiprofen following focal cerebral ischemia involves the NF-κB signaling pathway.

Some studies of animal models of middle cerebral artery occlusion indicate that inflammation plays a key role in the pathogenesis of cerebral ischemia and secondary damage. Flurbiprofen has been suggested to alleviate cerebral ischemia/reperfusion injury in both focal and global cerebral ischemia models, but the mechanisms underlying the protective action are still incompletely understood. In this study we want to investigate the protective effect of flurbiprofen after transient middle cerebral artery occlusion (MCAO) in rats and the role of the NF-κB signaling pathway on this neuroprotective effect.

HMGB1 enhances smooth muscle cell proliferation and migration in pulmonary artery remodeling.

HMGB1 is a necessary and critical mediator of acute lung injury and can act as a chemoattractant and anti-apoptosis factor in injury or repair in diseases. In this study we sought to determine whether HMGB1 is involved in the remodeling of pulmonary artery and investigate the mechanism. A rat model of pulmonary artery remodeling was successful induced with LPS infusion and the increasing of pulmonary arteries media was obviously inhibited in rats treated with thrice inject of HMGB1 neutralizing antibody.
