Objectives: To study the regularity of central response to thermal needle stimulation of "Zusanli" (ST36) at different temperature, and to analyze the temperature difference of central responses.
Methods: Six male C57BL/6j adult mice were used in the present study. For observing activities of neurons in the hindlimb region of left primary somatosensory cortex (S1HL, A/P=0.
Background: Few studies about the association between computed tomography (CT) perfusion imaging parameters and invasiveness in lung adenocarcinoma (LUAD) have been conducted using low dose spectral CT perfusion imaging. The purpose of this study was to investigate application of spectral revolution CT low-dose perfusion imaging in the differential diagnosis of different pathological subtypes of LUAD.
Methods: This was a cross-sectional study based on historical data from January 2018 to May 2019 in Peking University Cancer Hospital & Institute.
Background: Significant correlation between lymphatic, microvascular, and perineural invasion (LMPI) and the prognosis of pancreatic neuroendocrine tumors (PENTs) was confirmed by previous studies. There was no previous study reported the relationship between magnetic resonance imaging (MRI) parameters and LMPI.
Aim: To determine the feasibility of using preoperative MRI of the pancreas to predict LMPI in patients with non-functioning PENTs (NFPNETs).
Objective: To investigate the effects of mild moxibustion at 45°C on the chronic inflammatory response of the abdominal aorta in rats with hyperlipidemia and the effects of different moxibustion durations.
Methods: Thirty-six SD rats were randomly divided into the following groups: blank control group (2 weeks), model group (2 weeks), moxibustion group (2 weeks), blank group (4 weeks), model group (4 weeks), and moxibustion group (4 weeks). A model of hyperlipidemia with chronic inflammation was established through high-fat diet feeding for 8 weeks.
Objectives: To explore the potential of radiomics features to predict the histologic grade of nonfunctioning pancreatic neuroendocrine tumor (NF-PNET) patients using non-contrast sequence based on MRI.
Methods: Two hundred twenty-eight patients with NF-PNETs undergoing MRI at 5 centers were retrospectively analyzed. Data from center 1 (n = 115) constituted the training cohort, and data from centers 2-5 (n = 113) constituted the testing cohort.
Background: This study sought to investigate the applicability of different ultrasound (US) thyroid risk stratification systems in diagnosing medullary thyroid carcinoma (MTC) and determining the need for biopsy.
Methods: In total, 34 MTC nodules, 54 papillary thyroid carcinoma (PTC) nodules, and 62 benign thyroid nodules were examined in this study. All the diagnoses were histopathologically confirmed postoperatively.
Objective: To explore the antioxidant effect of moxibustion on vascular endothelial function and the under-lying mechanism.
Methods: Forty male SD rats were randomly divided into blank, model, moxibustion and endothelial nitric oxide synthase (eNOS) inhibitor groups, with 10 rats in each group. Hyperlipidemia rat model was established by high fat diet for 8 weeks.
Background: Patients with colorectal liver metastases (CRLM) combined with hepatic lymph node (HLN) metastases have a poor prognosis. In this study, we developed and validated a model using clinical and magnetic resonance imaging (MRI) parameters to predict HLN status before surgery.
Methods: A total of 104 CRLM patients undergoing hepatic lymphonodectomy with pathologically confirmed HLN status after preoperative chemotherapy were enrolled in this study.

Mn-N-C materials have received increasing interest in recent years because of their low Fenton reactivity and ORR activity comparable to those of their Fe-N-C and Co-N-C counterparts. In this contribution, an atomically dispersed Mn-N-C electrocatalyst with a prominent oxygen reduction performance was constructed by employing a cationic Cd-MOF as a precursor that can facilely and accurately introduce MnO anions through anion exchange. The best-performing Mn-N-C catalyst displays a 0.

Preoperative imaging indicators which can be used to predict LARS is unknown. We proposed preoperative MRI parameters for identifying major LARS.

This study aimed to explore the efficacy of perioperative second-line chemotherapy in prolonging survival in those patients.
Methods: Patients who underwent liver resection, with resectable liver metastases that occurred within 12 months after the last cycle of adjuvant chemotherapy for CRC, from January 2006 to December 2019, were included.
Background: The cT3 substage criteria based on extramural depth of tumor invasion in rectal cancer have several limitations.
Objective: This study proposed that the distance between the deepest tumor invasion and mesorectal fascia on pretherapy MRI can distinguish the prognosis of patients with cT3 rectal cancer.
Design: This is a cohort study.
Accurate evaluation of tumor response to preoperative chemotherapy is crucial for assigning appropriate patients with colorectal liver metastases (CRLM) to surgery or conservative therapy. However, there is no well-recognized method for predicting pathological response before surgery. Our study constructed and validated a deep learning algorithm using prechemotherapy and postchemotherapy magnetic resonance imaging (MRI) to predict pathological response in CRLM.

A highly active and stable Fe3C-containing Fe/N/C catalyst, derived from a cationic Cd(ii)-based metal-organic framework involving accurate control over Fe-doping via anion-exchange with potassium ferricyanide, shows superior oxygen reduction performance over the benchmark Pt/C catalyst in an alkaline electrolyte.
