This study sought to compare the therapeutic effects of angiotensin II (ANG II) and norepinephrine (NE) on cecal ligation and puncture (CLP)-induced septic acute kidney injury (AKI) in rats.
Sepsis shock was induced in anesthesia Sprague-Dawley male rats by CLP model for 24 hours. A total of 40 rats were divided into five groups, including control group, sham group, CLP group, CLP + ANG II group, and CLP + NE group. CLP + ANG II and CLP + NE group were administration of ANG II or NE after sepsis shock respectively, maintaining the MAP at 75-85 mmHg. CLP group was administration of saline for contrast. At 0, 18, 24 hours measured the renal blood grades and resistant index (RI) by ultrasound equipment. At 6, 12, 18 and 24 hours collected 0.5 mL blood sample for creatinine and lactic acid examination. Rats were observed for 24 hours after CLP procedure and then sacrificed for subsequent examination, rat serum were used to determine the levels of inflammatory response factors, kidney tissues were used to examine the oxidative stress factors and mitochondrial related proteins." We added the sentence as following "The AMPK, PGC-1α and NRF-2 expression in renal cortex was significantly increased in the CLP + ANG II group.
Compared to the vehicle treatment, both ANG II and NE administration restored the decrease in the mean arterial pressure (MAP) and alleviated mitochondrial impairments in CLP rats. However, only ANG II alleviated CLP-induced abnormalities in serum creatinine and lactic acid concentrations, renal blood flow, the renal resistant index, renal histopathology, the production of proinflammatory cytokines, and oxidative stress markers in rats. ANG II was also found to be superior to NE in reversing the CLP-induced suppression of mitochondrial biogenesis-related protein expression in the kidneys of rats.
ANG II was better than NE in alleviating CLP-induced septic AKI in rats.

Personalized three-dimensional (3D) reconstruction can help surgeons to overcome technical challenges and variations of pulmonary anatomic structures in the performance of uniportal video-assisted thoracoscopic surgery (UVATS), thus improving the safety and efficacy of the procedure. This study aims to evaluate the utility of preoperative 3D-CT bronchography and angiography (3D-CTBA) with Exoview software in the assessment of anatomical variations of pulmonary vessels, and to analyze short-term surgical outcomes in patients undergoing UVATS lobectomy.
We retrospectively analyzed the data of 198 consecutive patients who underwent curative UVATS lobectomy between November 2019 and September 2020. The patients were divided into an "Exoview" group (n=53) and a "non-Exoview" group (n=145). We performed 11 propensity score matching and compared intraoperative and postoperative outcomes between the two groups. A subgroup analysis of 74 patients who underwent single-direction uniportal lobectomy was also conductesonalized preoperative 3D-CT bronchography and angiography helped to clearly visualize the pulmonary anatomical structures and could contribute to the safe and efficient performance of UVATS anatomical lobectomy.
Studies have shown that the ability of the myocardium to tolerate ischemia becomes significantly compromised with age. During ischemia, several endogenous protective signals are activated to protect the heart from injury, among which extracellular-signal regulated kinase (ERK) 1/2 signaling has been established as playing a pivotal role. However, in aging hearts, the activation of ERK1/2 is compromised. Mitogen-activated protein kinase/ERK kinase (MEK) is a major regulator of ERK1/2 signaling. In the present study, we investigated whether transduction of CaMEK, a constitutively activated MEK, using adeno-associated virus serotype 9 (AAV9) could protect the aging heart against ischemia.
Myocardial ischemia models were established in aging mice and senescent cardiomyocytes, and AAV9-mediated delivery of CaMEK was applied. Echocardiography, fluorescent staining, transmission electron microscopy, flow cytometry, and immunoblotting were used to explore the effects of CaMEK and their underlying mechanism.
AAVduced myocardium injury in the aging heart, at least in part, through inhibition of mitochondrial fragmentation. Therefore, AAV9-CaMEK is a potential intervention for prevention of ischemia-induced injury of the aging myocardium.
The butyrophilin (BTN) family has many members with diverse functions related to immunomodulation, initiation and progression of tumors. BTN3A3 belongs to the BTN family, and exploring its expression and correlation with the prognosis of non-small cell lung cancer (NSCLC) patients has great clinical significance.
Clinical specimens were used to detect BTN3A3 expression. Small interfering RNA (siRNA) was used to knock down BTN3A3 and analyze the proliferative, migratory and invading ability of the transfected NSCLC cells. Multiplex immunofluorescence staining was used to detect the expression of BTN3A3 protein in the tumor microenvironment (TME). We analyzed the relationship between the expression of BTN3A3 and the clinicopathological features and prognosis of NSCLC patients.
The expression of BTN3A3 in NSCLC tissues was significantly lower than in adjacent tissues, and patients with low expression of BTN3A3 had late clinical stages and lower degree of tumor differentiation. Knocking down BTN3A3 promoted the proliferation, migration and invasion of NSCLC. In the TME, the density of BTN3A3+ tumor cells positively correlated with the density of CD8+ T cells, and the patients with low expression of BTN3A3 had poor overall survival (OS).
Changes in the BTN3A3 expression level may play a potential key role in the carcinogenesis and development of NSCLC. Patients with low expression of BTN3A3 showed a more aggressive and invasive phenotype and a lower level of CD8+ T-cell infiltration, which may be an important factor affecting the OS of NSCLC patients.

This study aimed to investigate the microbiol distribution of intra-abdominal infection in patients with acute pancreatitis, and to develop a reliable prediction model to guide the use of antibiotics.
Inpatient with acute pancreatitis between January 2015 and June 2020 were enrolled in the study. Participants were divided into the intra-abdominal infection group and non-infection group. Isolated pathogens and antibiotic susceptibility were documented. Characteristics parameters, laboratory results, and outcomes were also compared. Least absolute shrinkage and selection operator (LASSO) regression model was used to select the risk factors associated with intra-abdominal infection in patients with acute pancreatitis. Logistic regression analysis, random forest model, and artificial neural network were also used to validate the performance of the selected predictors in intra-abdominal infection prediction. A novel nomogram based on selected predictors was established to provide individualized risk of develop factors and the new nomogram based on these could help clinicians estimate the risk of intra-abdominal infection and optimize antimicrobial prescription for acute pancreatitis patients.
Multidrug-resistant bacteria were quite common in intra-abdominal infection. IAP, APACHE II, CTSI, the severity of pancreatitis, and ICU admission were identified as risk factors and the new nomogram based on these could help clinicians estimate the risk of intra-abdominal infection and optimize antimicrobial prescription for acute pancreatitis patients.
The factors for left recurrent laryngeal nerve (RLN) lymph node (LN) metastasis have important guiding significance for whether the left RLN LNs should be dissected in patients with esophageal squamous cell carcinoma (ESCC), but few studies are currently available. To analyze the risk factors of LN metastasis of the left RLN area and to assess which LNs should be dissected in ESCC.
This was a retrospective study of patients who underwent McKeown minimally invasive esophagectomy (MIE) (no neoadjuvant therapy) at Tianjin Medical University Cancer Institute and Hospital (from January 2016 to December 2019). The detection of left RLN LNs using enhanced computed tomography (CT) was compared with the pathological examination.
Of the total 94 participants, 43 had LN metastasis. link3 The metastatic LNs were mainly located next to left (18.1%) and right (14.9%) RLN, and the left gastric artery (13.8%). Tumor size, LN size, tumor invasion (T stage), N stage, and tumor node metastasis (TNM) stage were associated with left RLN LNs metastasis, while LN size was the only independently associated factor [odds ratio (OR) =1.
