Background: Blastocystis hominis (Bh) is zoonotic parasitic pathogen with a high prevalent globally, causing opportunistic infections and diarrhea disease. Human immunodeficiency virus (HIV) infection disrupts the immune system by depleting CD4 T lymphocyte (CD4 T) cell counts, thereby increasing Bh infection risk among persons living with HIV (PLWH). However, the precise association between Bh infection risk and HIV-related biological markers and treatment processes remains poorly understood.

Article Synopsis
  • * Factors influencing the prognosis of MDR-PTB include patient demographics, disease specifics, lung imaging, and treatment adherence.
  • * Current research mostly uses limited data to predict treatment outcomes, suggesting that multi-modal deep learning could improve personalized treatment plans and patient management.

Background: Influenza can fall into three categories according to severity: mild influenza, severe influenza, and critical influenza. Severe influenza can result in critical illness and sometimes death particularly in patients with comorbidities, advanced age, or pregnancy. Neuraminidase inhibitors (NAIs) are the only antiviral drugs in widespread use for influenza.

The purpose of this study was to investigate the inhibitory effects of the main active components of Salviae Miltiorrhizae Radix et Rhizoma on the metabolism of tacrolimus mediated by CYP3 A4/5 enzyme, so as to predict the potential drug-drug interaction(DDI) in clinical use. First, the reversible inhibitory activities of five active components of Salviae Miltiorrhizae Radix et Rhizoma(tanshinone Ⅰ, tanshinone Ⅱ_A, cryptotanshinone, salvianolic acid B, dihydrotanshinone Ⅰ) on the metabolism of tacrolimus was investigated by using human liver microsomes(HLM) and recombinant human CYP3 A4/5 enzyme in vitro, then the dose-dependent inhibition of CYP3 A4/5 activity was calculated in HLM. Finally, the time-dependent inhibition(TDI) activities of five active components were studied in HLM through the robust single point inhibition test.

The Chinese medicinal formula, Qinggan (QG) Huoxue (HX) Recipe (R) exerts a range of pharmacological effects, including reversible steatosis, decreased levels of inflammatory cytokines and lipid peroxidation resistance. The aim of the present study was to determine the specific mechanisms of QGHXR hepatoprotection through the lipopolysaccharide-Kupffer cell (LPS-KC) signal conduction pathway in rats with alcoholic liver disease (ALD). ALD rats were exposed to the compound factors, QGR and HXR.

Lingguizhugan decoction (LGZG), a classic traditional Chinese medicine (TCM) formula, has been used to treat obesity and hyperlipidemia in recent years, but the related mechanisms underlying the regulation of lipid metabolism by LGZG are not clear yet. Here, we reported the effectiveness and possible mechanisms of LGZG on rats with fatty liver disease induced by high-fat diet (HFD). Our results demonstrated that LGZG significantly attenuated HFD-induced fatty liver disease, as measured by body weight, liver index, epididymal fat pad-body weight ratio (EFP/BW), liver injury, and hepatic triglycerides (TG) probably through increasing serum thyroid hormone levels, improving beta-oxidation (via modulation of TR β 1 and CPT1A expression), metabolism and transport (through modulation of SREBP-1c, ACSL and ApoB100 expression) of fatty acid.

Objective: To test whether nonalcoholic hepatic steatosis sensitizes carbon tetrachloride (CCl4)-induced liver injury, and to assess the therapeutic effect of Chinese medicine extracts of Dangfei Liganning capsules and their potential underlying mechanisms.

Methods: Male Wistar rats were fed a high-fat diet to induce nonalcoholic fatty liver disease (NAFLD) or a normal diet (N). Eight weeks later, a nonlethal dose of CCl4 was applied intraperitoneally.
