Background: Cerebral ischemia/reperfusion (I/R) injury is a serious vascular disease with extremely high mortality and disability rate. Bakuchiol (BAK) was found in leaves and seeds of Psoralea corylifolia Linn and has been shown to decrease inflammation and reduce oxidative stress, while the mechanism of BAK in ameliorating cerebral I/R injury remains unclear.
Methods: Middle cerebral artery occlusion reperfusion (MACO/R) was used to establish mouse model.
Objectives: To observe the effect of electroacupuncture (EA) at "Zusanli"(ST36) on intestinal mucosal damage, intestinal mucosal oxidative stress injury and apoptosis induced by 5-fluorouraeil (5-FU) chemotherapy in colorectal cancer-bearing mice.
Methods: Thirty male BALB/c mice were randomly divided into normal control, colorectal cancer (CT26), 5-FU, non-acupoint and ST36 groups, with 6 mice in each group. Except for those of the normal control group, mice of the remaining 4 groups received subcutaneous implantation of colorectal CT26 cell suspension (0.
Background: Heart failure (HF), manifested as a severe or end stage of various cardiac diseases, is characterized by increased incidence, mortality, re-hospitalization, and economic burden. Myocardial infarction (MI) is one of the most common and important causes of HF. Since 2005, acute MI (AMI)-associated mortality in China has been on the rise, and MI accounts for 23.

Therefore, it is urgent to explore new treatment strategies for ovarian cancer. In this study, paclitaxel and emodin were encapsulated in different micelles, and loaded on the surface of the micelles with epidermal growth factor (EGF) as the targeting molecule, made compound formulations in proportion.

To investigate the effects of fatty acid binding protein 5(FABP5)- peroxisome proliferator-activated receptor gamma(PPARγ) signaling pathway on learning-memory ability and lipid metabolism in rats with vascular dementia(VD) and its mechanisms. ①VD model rats were established by ligating bilateral common carotid artery. These rats were divided into three groups: normal group (WT group), sham-operated group (sham group) and VD model group; ②WT group and FABP5 inhibitor group were set up.

Although the gastrointestinal (GI) tract is the most common predilection site of CFT, the clinicians, even including pathologist, generally consider it as GI stromal tumor (GIST) or other submucosal tumors such as schwannoma and leiomyoma.
Patient Concerns: A 55-year-old man presented with complaints of epigastric discomfort and abdominal distention for more than 1 year.
Multidrug resistance (MDR) has emerged as the main problem in anti-cancer therapy. Although MDR involves complex factors and processes, the main pivot is the expression of multidrug efflux pumps. P-glycoprotein (P-gp) belongs to the family of adenosine triphosphate (ATP)-binding cassette (ABC) transporters.

Methods: 20 SD rats were randomly divided into two groups, the blank and Acanthopanax senticosus polysaccharides treatment groups, which were treated with saline and Acanthopanax senticosus polysaccharide for 20 days. On the 21th day,heart tissue were collected and each sample extract was analyzed by UPLC-Q-TOF/MS.

ACD in mice was induced by the repeated application of 2,4-dinitrochlorobenzene (DNCB) to their skins. The mice were orally administered TGP (35, 70, and 140mg/kg/d) and prednisone (Pre, 5mg/kg/d) from day 1 to day 7 after immunization.

In this retrospective study, we included a total of 290 patients with advanced non-small cell lung cancer (NSCLC) who received treatment with epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) and chemotherapy.
Methods: The BIM deletion polymorphism of each patient was detected by polymerase chain reaction.
DNA methylation is an important epigenetic modification that regulates temporal and spatial expression of genes for controlling cell fate and differentiation. Recently, DNA methylation has been demonstrated to be required for vertebrate early embryogenesis. Loss of Dnmt genes in zebrafish and mice caused defects in organogenesis and tissue terminal differentiation.

Black nephrite is a very uncommon jade type currently found only at Karakashi. In order to study the spectral characteristics and color-genetic mechanism of the black nephrite, samples collected from Karakashi were studied using EMPA, IR, Raman and XRD. The results are as follows: nephrite with different color has nearly the same major chemical compostions, while the black ones contain higher carbon; nephrite with different color has similar vibration spectrum, while the black ones show characteristic peak of graphite.
