The neutrophil-to-lymphocyte ratio and lactate dehydrogenase combined in predicting liver metastasis and prognosis of colorectal cancer.

Background: The neutrophil-to-lymphocyte ratio (NLR) and lactate dehydrogenase (LDH) level are inflammatory markers related to tumor growth and metabolism. This study investigated the value of preoperative NLR, LDH and the combination of NLR and LDH (NLR-LDH) for predicting colorectal cancer liver metastasis (CRLM) and tumor prognosis in the early stages of colorectal cancer (CRC).

Materials And Methods: Three hundred patients undergoing CRC resection were included.

Effect of Nurse-Led Individualised Self-Care Model on Myocardial Infarction Patients with Diabetes: A Randomised Controlled Pilot Trial.

Background: To assess the effectiveness of the nurse-led individualised self-care model on myocardial infarction (MI) patients with diabetes.

Methods: A total of 120 MI patients were enrolled from May 2020 to December 2021. The intervention group received the nurse-led individualised self-care model (n = 60), whereas the control group only received routine health education (n = 60).

Microbial spectrum and drug resistance of pathogens cultured from gallbladder bile specimens of patients with cholelithiasis: A single-center retrospective study.

Background: Bacterial infection is an important cause of cholelithiasis or gallstones and interferes with its treatment. There is no consensus on bile microbial culture profiles in previous studies, and identified microbial spectrum and drug resistance is helpful for targeted preventive and therapeutic drugs in the perioperative period.

Aim: To analyze the bile microbial spectrum of patients with cholelithiasis and the drug susceptibility patterns in order to establish an empirical antibiotic treatment for cholelithiasis-associated infection.

Shuxuetong for Prevention of recurrence in Acute Cerebrovascular events with Embolism (SPACE) trial: rationale and design.

Backgrounds: Embolic stroke is one of the main mechanisms of ischaemic stroke. Even if treated with recommended antithrombotic agents, stroke recurrence remains high. The Shuxuetong injection, a purified extract of traditional Chinese medicine widely used for thrombus diseases in clinical practice in China, could be a promising agent to prevent stroke recurrence.

[Purification and biochemical function of Astragalus membtanaceus pathogenesis-related protein 10].

Astragalus membranaceus pathogenesis-related protein 10 (AmPR-10) is largely expressed in case of environmental pressure and pathogen invasion. This study aims to explore the biochemical functions of AmPR-10. The dried root of Astragalus membranaceus was mechanically homogenized and extracted by Tris-HCl buffer to obtain its crude extract, which was then purified by anion exchange chromatography and gel filtration chromatography to obtain electrophoretically pure AmPR-10.

Effect of β-elemene on the kinetics of intracellular transport of d-luciferin potassium salt (ABC substrate) in doxorubicin-resistant breast cancer cells and the associated molecular mechanism.

In order to explore the mechanism of the reversing multidrug resistance (MDR) phenotypes by β-elemene (β-ELE) in doxorubicin (DOX)-resistant breast cancer cells (MCF-7/DOX), both the functionality and quantity of the ABC transporters in MCF-7/DOX were studied. Bioluminescence imaging (BLI) was used to study the efflux of d-luciferin potassium salt, the substrate of ATP-binding cassette transporters (ABC transporters), in MCF-7/DOX cells treated by β-ELE. At the same time three major ABC transport proteins and genes-related MDR, P-glycoprotein (P-gp, ABCB1) and multidrug resistance-associated protein 1 (MRP, ABCC1) as well as breast cancer resistance protein (BCRP, ABCG2) were analyzed by q-PCR and Western blot.

Dual face of axonal inhibitory inputs in the modulation of neuronal excitability in cortical pyramidal neurons.

Limited by the tiny structure of axons, the effects of these axonal hyperpolarizing inputs on neuronal activity have not been directly elucidated. Here, we imitated these processes by simultaneously recording the activities of the somas and proximal axons of cortical pyramidal neurons. We found that spikes and subthreshold potentials propagate between somas and axons with high fidelity.

Inflammatory myofibroblastic tumor of the liver following renal transplantation.

Inflammatory myofibroblastic tumor (IMT), previously named inflammatory pseudotumor, is a benign lesion, the exact etiology of which remains obscure; immunosuppression and infections have been speculated to be responsible for the development of pseudotumor. IMT associated with transplantation is rarely reported; we report the first case of IMT of the liver in a renal transplantation patient, who presented with symptoms of abdominal pain. The findings of computed tomography suggested hepatocellular carcinoma or liver abscess, and surgical resection was performed.

Functional distinction of rat liver natural killer cells from spleen natural killer cells under normal and acidic conditions in vitro.

Background: The microenvironment within solid tumors has often been shown to exhibit an acidic extracellular pH. Although the morphologic and functional differences in natural killer (NK) cells of the liver and spleen have been reported previously under physiological conditions, the difference under acidic conditions is still unclear. This study was to investigate the differences in the morphological and functional characteristics between rat liver and spleen NK cells under normal and acidic conditions in vitro.

[Management of postoperative chyle leak after surgery for digestive malignancies].

Objective: To investigate the treatment of postoperative chyle leak after surgery for digestive malignancies.

Methods: From December 2008 to February 2012, in the Sun Yat-sen Memorial Hospital of Sun Yat-sen University, clinical data of 19 patients with chyle leak after digestive system cancer surgery were retrospective analyzed.

Results: Nineteen cases of chyle leak were all identified between the second and the fourth postoperative day and were all initially managed with conservative treatment including early fasting, parenteral nutrition(PN), 24-hour continuous infusion of somatostatin, and low pressure suction drainage.

Donor liver natural killer cells alleviate liver allograft acute rejection in rats.

Background: Liver enriched natural killer (NK) cells are of high immune activity. However, the function of donor liver NK cells in allogeneic liver transplantation (LTx) remains unclear.

Methods: Ten Gy of whole body gamma-irradiation (WBI) from a 60Co source at 0.

Selaginellin A and B, two novel natural pigments isolated from Selaginella tamariscina.

Two new unusual natural pigments were first isolated from the whole herbs of Selaginella tamariscina. The structure of selaginellin A (1) was established as (R,S)-4-[(4'-hydroxy-3-((4-hydroxyphenyl)ethynyl)biphenyl-2-yl)(4-hydroxyphenyl)methylene]-2,5-cyclohexadien-1-one and selaginellin B (2) as (R,S)-4-[(4'-methoxy-4-(methyl)-3-((4-methoxyphenyl)ethynyl)biphenyl-2-yl)(4-methoxyphenyl)methylene]-2,5-cyclohexadien-1-one, along with four known biflavonoids, amentoflavone (3), hinokiflavone (4), heveaflavone (5), and 7''-O-methylamentoflavone (6). Their chemical structures were elucidated by spectral analysis of electrospray ionization mass spectroscopy (ESI-MS), one-dimensional nuclear magnetic resonance spectroscopy (1D-NMR) and two-dimensional-nuclear magnetic resonance spectroscopy (2D-NMR) including (1)H-NMR, (13)C-NMR, distortionless enhancement by polarization transfer (DEPT) and heteronuclear multiple bond coherence (HMBC), and single-crystal X-ray diffraction techniques.
