Three-pressure prediction method of jointing well-seismic data in JT1 well area of Sichuan Basin in China.

With the high yield of many wells represented by Well JT1 in the Maokou Formation, has catalyzed a surge in exploration activities along the platform margin facies of the Maokou Formation in central Sichuan and further showed the significant exploration potential of the Maokou Formation in the northern slope. However, the fracture cave body of the Maokou Formation exhibits a high degree of development, strong longitudinal and horizontal heterogeneity, large formation pressure differences, and drilling events such as gas kicks and lost circulation occur frequently, which seriously affects the efficient implementation of drilling. Understanding the spatial distribution of the three-pressure in the formation can help better deal with and solve the above problems.

Methods: From November 2020 to February 2023, 54 inpatients with MDD were randomly allocated to TSD and Control groups.

Explaining the stability of cooperation in agricultural industry chains based on the institutional theory: Multiple mediating effects of perceived value and trust.

Introduction: Due to the superposition of multiple complex socioeconomic environments and the complexity and uncertainty of the agricultural industry chain itself, the agricultural industry chain has become unstable, jeopardizing its long-term sustainability.

Methods: The purpose of this study is to construct and validate a stability mechanism model of cooperative relationships within agricultural industry chains based on the institutional theory. The questionnaire survey method was used for empirical analysis.

Role of annexin A family in tumorigenesis and chemoresistance of gastric cancer.

Gastric cancer (GC) is one of the most common cancer types and the fourth leading cause of cancer-related mortality among all malignant tumors worldwide. Due to insidious onset and lack of reliable early diagnostic markers, most GC patients are at an advanced stage at the time of diagnosis. Annexin is an evolutionally-conserved Ca2+-dependent phospholipid-binding protein superfamily, including five members (A, B, C, D, and E).

Fasudil prevents liver fibrosis activating natural killer cells and suppressing hepatic stellate cells.

Background: Fasudil, as a Ras homology family member A (RhoA) kinase inhibitor, is used to improve brain microcirculation and promote nerve regeneration clinically. Increasing evidence shows that Rho-kinase inhibition could improve liver fibrosis.

Aim: To evaluate the anti-fibrotic effects of Fasudil in a mouse model of liver fibrosis induced by thioacetamide (TAA).

Effect of KIF22 on promoting proliferation and migration of gastric cancer cells via MAPK-ERK pathways.

Background: Gastric cancer (GC) is one of the most globally prevalent cancers in the world. The pathogenesis of GC has not been fully elucidated, and there still lacks effective targeted therapeutics. The influence of altered kinesin superfamily protein 22 (KIF22) expression in GC progression is still unclearly.

Ginsenoside-Rb1 Improved Diabetic Cardiomyopathy through Regulating Calcium Signaling by Alleviating Protein O-GlcNAcylation.

Ginsenoside-Rb1 (Rb1), a major active component of ginseng, has many benefits for cardiovascular disease and diabetes mellitus (DM), but the effect and mechanism on diabetic cardiomyopathy are not clear. In the present study, we found that Rb1-feeding significantly improved cardiac dysfunction and abnormal cardiomyocytes calcium signaling caused by diabetes. This improved calcium signaling was because Rb1 reduced Ca leakage caused by overactivated ryanodine receptor 2 (RyR2) and increased Ca uptake by sarcoplasmic reticulum Ca-ATPase 2a (SERCA 2a).

The intestinal microbial community dissimilarity in hepatitis B virus-related liver cirrhosis patients with and without at alcohol consumption.

Background: Chronic hepatitis B virus (HBV) infection-reduced liver functions are associated with intestinal microbial community dissimilarity. This study aimed to investigate the microbial community dissimilarity in patients with different grades of HBV-related liver cirrhosis.

Results: Serum endotoxin was increased with Child-Pugh (CP) class (A, B, and C).

Internal Mammary Sentinel Lymph Node Biopsy in Clinically Axillary Lymph Node-Positive Breast Cancer: Diagnosis and Implications for Patient Management.

Background: Routine performance of internal mammary sentinel lymph node biopsy (IM-SLNB) remains a subject of debate due to no clinical relevance in breast cancer, because it was performed only in clinically axillary lymph node (ALN)-negative patients. In this study, IM-SLNB was performed in clinically ALN-positive patients, and its impact on nodal staging and therapeutic strategy were subsequently analyzed.

Methods: Clinically ALN-positive patients who underwent IM-SLNB were enrolled in this prospective study.

Pharmacological inhibition of DNA methylation attenuates pressure overload-induced cardiac hypertrophy in rats.

Background: Heart failure is associated with altered gene expression and DNA methylation. De novo DNA methylation is associated with gene silencing, but its role in cardiac pathology remains incompletely understood. We hypothesized that inhibition of DNA methyltransferases (DNMT) might prevent the deregulation of gene expression and the deterioration of cardiac function under pressure overload (PO).

Targeting Chondroitin Sulfate Glycosaminoglycans to Treat Cardiac Fibrosis in Pathological Remodeling.

Background: Heart failure is a leading cause of mortality and morbidity, and the search for novel therapeutic approaches continues. In the monogenic disease mucopolysaccharidosis VI, loss-of-function mutations in arylsulfatase B lead to myocardial accumulation of chondroitin sulfate (CS) glycosaminoglycans, manifesting as myriad cardiac symptoms. Here, we studied changes in myocardial CS in nonmucopolysaccharidosis failing hearts and assessed its generic role in pathological cardiac remodeling.

Internal Mammary Sentinel Lymph Node Biopsy With Modified Injection Technique: High Visualization Rate and Accurate Staging.

Although the 2009 American Joint Committee on Cancer incorporated the internal mammary sentinel lymph node biopsy (IM-SLNB) concept, there has been little change in surgical practice patterns because of the low visualization rate of internal mammary sentinel lymph nodes (IMSLN) with the traditional radiotracer injection technique. In this study, various injection techniques were evaluated in term of the IMSLN visualization rate, and the impact of IM-SLNB on the diagnostic and prognostic value were analyzed.Clinically, axillary lymph nodes (ALN) negative patients (n = 407) were divided into group A (traditional peritumoral intraparenchymal injection) and group B (modified periareolar intraparenchymal injection).

Crystalline CO2-based polycarbonates prepared from racemic catalyst through intramolecularly interlocked assembly.

The crystalline stereocomplexed polycarbonates can be prepared by mixing enantiopure polymers with opposite configuration, which derived from the asymmetric copolymerization with CO2 using enantiopure catalyst or/and chiral epoxides. Herein, we develop a powerful strategy for producing crystalline intramolecular stereocomplexed polycarbonates from racemic catalysts, which possess similar thermal stability and crystalline behaviour in comparison with the stereocomplexes by mixing opposite enantiopure polymers. Living polymer chains shuttle between catalyst molecules with different configurations to produce diastereomeric active species which is suggested to be responsible for the formation of isotactic multiblock polycarbonates in racemic bimetallic cobalt catalyst-mediated stereoselective copolymerization of CO2 and meso-epoxides.

Toll-like receptor 2 promotes T helper 17 cells response in hepatitis B virus infection.

Purpose: Innate and adaptive immune responses play vital roles in initiating and maintaining the immunological homeostasis in both physiological and pathological processes. However, the expression and function of the important cells and molecules as well as their interaction in hepatitis B virus (HBV) infection has not been well elucidated. The aim of the current study was to determine the pattern of Toll-like receptor 2 (TLR2) in T cells in HBV infection and the function of TLR2 in regulation of T helper 17 (Th17) cells response.

Exclusion of integrins from CNS axons is regulated by Arf6 activation and the AIS.

Integrins are adhesion and survival molecules involved in axon growth during CNS development, as well as axon regeneration after injury in the peripheral nervous system (PNS). Adult CNS axons do not regenerate after injury, partly due to a low intrinsic growth capacity. We have previously studied the role of integrins in axon growth in PNS axons; in the present study, we investigate whether integrin mechanisms involved in PNS regeneration may be altered or lacking from mature CNS axons by studying maturing CNS neurons in vitro.

Expression profiles of circulating cytokines, chemokines and immune cells in patients with hepatitis B virus infection.

Background: Immune cells and molecules play a vital role in initiating, maintaining, regulating immunological homeostasis and inflammation in many pathological and physiological processes; however, the changes on expressions and functions of these cells and molecules in hepatitis B virus (HBV) infection have not been elucidated well.

Objectives: The current study aimed to determine the expression pattern of different cytokines, chemokines, immune cells in HBV infection and their association with disease progression.

Patients And Methods: Sixty-nine patients with chronic HBV infection were enrolled.

Targeting inhibitory chondroitin sulphate proteoglycans to promote plasticity after injury.

Chondroitin sulphate proteoglycans (CSPGs) are one of the major families of inhibitory extracellular matrix molecules in the central nervous system. The expression of various CSPGs is strong during early nervous system development; however, it is downregulated during maturation and up-regulated again after nervous system injury. In vivo injection of an enzyme called chondroitinase ABC, which removes the inhibitory chondroitin sulphate chains on the CSPGs, in the injured area promotes both the regeneration and plasticity of the neurons.

[A novel technique for scintigraphic visualization of internal mammary sentinel lymph nodes in breast cancer patients].

Objective: To explore the effects of different injection techniques of radiotracer on the visualization rate of internal mammary sentinel lymph nodes (IMSLN) in breast cancer patients.

Methods: A series of 137 consecutive breast cancer patients was included in this prospective study. Fifty-eight patients (group A) received the radiotracer (99)Tc(m)-sulphur colloid injected only into 1-2 points in the breast parenchyma in one quadrant, and seventy-nine patients (group B) received the radiotracer injection into the breast parenchyma in two quadrants of the breast.

Combination treatment with chondroitinase ABC in spinal cord injury--breaking the barrier.

After spinal cord injury (SCI), re-establishing functional circuitry in the damaged central nervous system (CNS) faces multiple challenges including lost tissue volume, insufficient intrinsic growth capacity of adult neurons, and the inhibitory environment in the damaged CNS. Several treatment strategies have been developed over the past three decades, but successful restoration of sensory and motor functions will probably require a combination of approaches to address different aspects of the problem. Degradation of the chondroitin sulfate proteoglycans with the chondroitinase ABC (ChABC) enzyme removes a regeneration barrier from the glial scar and increases plasticity in the CNS by removing perineuronal nets.

Internal mammary sentinel lymph node biopsy should still be performed, especially in the patient with clinically positive axillary lymph nodes.

Current studies suggest that the internal mammary sentinel lymph node biopsy (IM-SLNB) should not be performed routinely, for it did not alter clinical management of breast cancer patients in terms of adjuvant treatment. However, consideration should be given to the fact, the study population in all current research relate to IM-SLNB is the patients with clinically negative axillary lymph nodes. As internal mammary lymph nodes metastases are mostly found concomitantly with axillary metastases, clinical trials currently fail to evaluate the status of internal mammary lymph nodes who really in need.

A core competency model for Chinese baccalaureate nursing graduates: a descriptive correlational study in Beijing.

Background: A review of the literature showed that the core competencies needed by newly graduated Chinese nurses were not as of yet undocumented.

Objective: To develop a psychometrically sound instrument for identifying and measuring the core competencies needed by Chinese nursing baccalaureate graduates.

Design: Descriptive correlational and multicentre study.

Combination treatment with anti-Nogo-A and chondroitinase ABC is more effective than single treatments at enhancing functional recovery after spinal cord injury.

Anti-Nogo-A antibody and chondroitinase ABC (ChABC) enzyme are two promising treatments that promote functional recovery after spinal cord injury (SCI). Treatment with them has encouraged axon regeneration, sprouting and functional recovery in a variety of spinal cord and central nervous system injury models. The two compounds work, in part, through different mechanisms, so it is possible that their effects will be additive.
