Objective To investigate the influence of transforming growth factor-?1(TGF-?1) on macrophage scavenger receptor (ScR) class A and B(ScR-B,CD36) in order to provide theoretical foundation for expounding the formation and therapy of atherosclerosis(AS).Methods THP-1 derived macrophages were divided into control group and experimental group,the cells in experimental group were treated with 3.0 mg?L-1Anti TGF-?1 Ab,the cells in control group were treated with 3.0 mg?L-1 IgG. The 125I-acetylated low density lipoprotein (125I-Ac-LDL for ScR-A) and 125I-oxidized low density lipoprotein (125I-Ox-LDL for CD36) uptaking (including 4℃ binding,37℃ association and degradation) were measured respectively.Influence of anti TGF-?1 antibody (Anti TGF-?1 Ab) on the ScR-A and CD36 mRNA expressions in THP-1 derived macrophages was measured meanwhile,respectively.Results Compared with control group ( binding: 8.23 ?g?g-1 ?1.24 ?g?g-1 protein,association:45.69 ?g?g-1 ?6.92 ?g?g-1 protein,and degradation: 112.18 ?g?g-1 ?20.15 ?g?g-1 protein),Anti TGF-?1 Ab increased 125I-Ac-LDL binding(48.67 ?g?g-1 ?6.52 ?g?g-1 protein),association (412.30 ?g?g-1?12.21 ?g?g-1 protein),and degradation (896.48 ?g?g-1 ?32.74 ?g?g-1 protein) significantly (P

Gastric cancer is the most prevalent gastrointestinal tumor in China， threatening the life and health of patients. Surgery is one of the available therapies， which， however， induces postoperative gastrointestinal dysfunction （PGD） and other common complications. The pathogenesis of PGD is still unclear and no efficient targeted drug is available. In addition， the limited treatment measures fail to effectively improve gastrointestinal function. As a result， patients generally suffer from low quality of life and poor prognosis. In Chinese medicine， PGD belongs to the categories of "vomiting"， "stuffiness and fullness"， "regurgitation"， "abdominal distension"， "intestinal impediment"， and "intestinal accumulation". In recent years， there has been an explosion of research on the PGD of gastric cancer in Chinese medicine， and many research results have been obtained. On this basis， this study introduced PGD in modern medicine， and causes and pathogenesis， syndrome differentiation-based treatment， and clinical studies of PGD. It was found that diverse internal and external treatments are available in Chinese medicine for PGD such as internal use of Chinese medicine， Chinese medicine enema， auricular point seed-embedding， acupuncture， and moxibustion， which feature ease of implementation， small side effects， definite efficacy， and significant effect in combination with other therapies. This paper summarized the ideas and measures for treatment of PGD of gastric cancer by Chinese medicine， the research outcomes， limitations， and research directions， which can serve as a reference for further research on treatment of PGD of gastric cancer by Chinese medicine.

Activation of the heart normally begins in the sinoatrial node (SAN). Electrical impulses spontaneously released by SAN pacemaker cells (SANPCs) trigger the contraction of the heart. However, the cellular nature of SANPCs remains controversial. Here, we report that SANPCs exhibit glutamatergic neuron-like properties. By comparing the single-cell transcriptome of SANPCs with that of cells from primary visual cortex in mouse, we found that SANPCs co-clustered with cortical neurons. Tissue and cellular imaging confirmed that SANPCs contained key elements of glutamatergic neurotransmitter system, expressing genes encoding glutamate synthesis pathway (Gls), ionotropic and metabotropic glutamate receptors (Grina, Gria3, Grm1 and Grm5), and glutamate transporters (Slc17a7). SANPCs highly expressed cell markers of glutamatergic neurons (Snap25 and Slc17a7), whereas Gad1, a marker of GABAergic neurons, was negative. Functional studies revealed that inhibition of glutamate receptors or transporters reduced spontaneous pacing frequency of isolated SAN tissues and spontaneous Ca
