Bear Bile Powder Ameliorates LPS-Induced Acute Lung Injury by Inhibiting CD14 Pathway and Improving Intestinal Flora: Exploration of "Fei (Lung)-Dachang (Large Intestine) Interaction".

Objective: To explore the effect of bear bile powder (BBP) on acute lung injury (ALI) and the underlying mechanism.

Methods: The chemical constituents of BBP were analyzed by ultra-high-pressure liquid chromatography-mass spectrometry (UPLC-MS). After 7 days of adaptive feeding, 50 mice were randomly divided into 5 groups by a random number table (n=10): normal control (NC), lipopolysaccharide (LPS), dexamethasone (Dex), low-, and high-dose BBP groups.

[Photoacoustic imaging study on spatial structure of microvessels around acupoints in mice with acute myocardial ischemia].

Objective: To observe the changes of microvascular structure of acupoints caused by myocardial ischemia, so as to explore the application of photoacoustic imaging technology in the research of acupoint sensitization.

Methods: Twelve BALB/c mice were randomly divided into normal, sham operation and acute myocardial ischemia (AMI) model groups, with 4 mice in each group. AMI model was established by ligating the left anterior descending coronary artery.

[Effect of electroacupuncture on learning-memory ability and expression of IL-1β, IL-6 and TNF-α in hippocampus and spleen in mice with Alzheimer's disease].

Objective: To explore the effect of electroacupuncture (EA) on the ability of spatial learning-memory and the expression of IL-1β, IL-6 and TNF-α in the hippocampus and spleen tissues and the number of hippocampal neurons and spleen lymphocytes in Alzheimer's disease (AD) mice, so as to study its mechanisms underlying improvement of AD.

Methods: Twenty-four SAMP8 mice were randomly and equally divided into AD model, EA and medication groups, and 8 SAMR1 mice were used as the control group. EA (2 Hz, 0.

Effects of Jian-Pi-Zhi-Dong Decoction on the Expression of 5-HT and Its Receptor in a Rat Model of Tourette Syndrome and Comorbid Anxiety.

BACKGROUND Anxiety is one of the common comorbidities of Tourette syndrome (TS). The serotonin (5-HT) system is involved in both TS and anxiety. Jian-pi-zhi-dong decoction (JPZDD) is widely used.
