The dynamics of patient visits to traditional Chinese medicine during the 2019 coronavirus pandemic.

Background: Large-scale epidemics have changed people's medical behavior, and patients tend to delay non-urgent medical needs. However, the impact of the pandemic on the use of complementary and alternative medicine remains unknown.

Methods: This retrospective study aimed to analyze the changes in the number of traditional Chinese medicine (TCM) patients and examine the epidemic prevention policy during the coronavirus disease 2019 (COVID-19) pandemic.

The proliferation and migration effects of huangqi on RSC96 Schwann cells.

This study evaluated the proliferation effects of huangqi on neuron regeneration. We investigated the molecular mechanisms, which include: (1) cyclin D1, A, E-cell cycle factors and MAPK signaling proliferation (2) FGF-2-UPA-MMPs migration signaling. After treatment with various Huanqi concentrations (1.

Immunoglobulin E and matrix metalloproteinase-9 in patients with different stages of coronary artery diseases.

The aims of this study were to identify levels of total immunoglobulin E (IgE) and matrix metalloproteinase (MMP)-9 in patients with different stages of coronary artery diseases. IgE, MMP-9, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), total cholesterol, low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL) and triglyceride (TG) were measured by fluorescence enzyme immunoassay, gelatin zymography, and autoanalyzer in normal subjects (n = 40), patients with stable angina pectoris (SAP, n = 40), patients with unstable angina pectoris (UAP, n = 40), patients with acute myocardial infarction (AMI, n = 40), or post-CABG-surgery of those acute myocardial infarction (P-CABG, n = 40). Compared with normal subjects, increased IgE but unchanged MMP-9, CPK, LDH were found in SAP group and UAP group, whereas IgE, MMP-9, CPK and LDH levels were all significantly increased in AMI group.

Hypoxia-induced compensatory effect as related to Shh and HIF-1alpha in ischemia embryo rat heart.

Chronic cardiac ischemia/hypoxia induces coronary collateral formation and cardiomyocyte proliferation. Hypoxia can induce cellular adaptive responses, such as synthesis of VEGF for angiogenesis and IGF-2 for proliferation. Both reduce apoptotic effects to minimize injury or damage.

The coexistence of nocturnal sustained hypoxia and obesity additively increases cardiac apoptosis.

Background: nocturnal sustained hypoxia during sleeping time has been reported in severe obesity, but no information regarding the cardiac molecular mechanism in the coexistence of nocturnal sustained hypoxia and obesity is available. This study evaluates whether the coexistence of nocturnal sustained hypoxia and obesity will increase cardiac Fas death receptor and mitochondrial-dependent apoptotic pathway.

Methods: 32 lean and 32 obese 5- to 6-mo-old rats with or without nocturnal sustained hypoxia were studied and assigned to one of four subgroups: normoxia lean (NL), normoxia obese (NO), hypoxia lean (HL, 12% O(2) for 8 h and 21% O(2) 16 h/day, 1 wk), and hypoxia obese (HO).
