PV-88 is the Ca2+ L channel blocker from pyrrole compounds, that has been used at hemorrhagic shock - HS (model of Shock was created by the method of (Wiggers-Feine) on 60th minute (intravenous administration, 3 mg/kg). Mean arterial pressure was 40 mmHg. Effects were studied on 80th minute after blood letting. Blood was exfused 40 ml/kg. Effect of PV-88 on redox processes in liver was studied. Experiments were carried out on male cats. Right lobe of the liver and the metabolic indices: ATP, CO, NAD, NADP, ALP, SDH, LDH were studied with the use of histochemistry (Pearse). Investigations have shown that on 80th minute after PV-88 administration CO (p<0.05), NADP (p<0.05), ALP (p<0.001), SDH (p<0.05), and LDH (p>0.05) were increased, while ATP (p<0.001) and NAD (p<0.001) were decreased. Increase in LDH was not statistically significant. According to the results of investigations, after administration of PV-88 at HS 60 on 80th minute, in liver increases oxygen concentration and aerobic process respectively.

Background: Currently, the treatment and prevention of erectile dysfunction (ED) remain highly challenging.
Aim: This study conducted a systematic druggable genome-wide Mendelian randomization (MR) analysis to identify potential therapeutic targets for ED.
Methods: A proteome-wide MR approach was employed to investigate the causal effects of plasma proteins on ED.

Rationale: Astragali radix-Salvia miltiorrhiza (AR-SM) is an herb pair with good therapeutic effects and is widely used. In this study, the in vitro and in vivo components of AR-SM were quickly classified and identified based on UHPLC-orbital mass spectrometry. This provided a basis for clarifying the bioactive substances after compatibility of AR and SM.

Phenolic compounds are typical organic pollutants which cause severe human health problems due to their teratogenesis, carcinogenesis, neurotoxicity, immunotoxicity and endocrine disruption. Natural laccase is a multicopper oxidase existing in bacteria, plants, and insects, which can accelerate the transformation of phenolic compounds to their less hazardous oxidized products under mild conditions without harmful byproducts. Despite eco-environmentally friendly property of laccase, it still faces constraints of widespread application attribute to its high cost, complex preparation, and vulnerability.

Background: Glycholic acid (GCA) can dynamically reflect the process of liver injury, and can be used for early diagnosis and curative effect evaluation of early hepatitis and cirrhosis. The highly sensitive detection of liver injury markers is conducive to a more accurate and effective auxiliary diagnosis of liver diseases. In addition, the low trigger potential helps to avoid more chemical interference and improve the detection sensitivity.
