We reported the inhibition of α-Hemolysin (Hla) production in methicillin-resistant Staphylococcus aureus USA300 by osthole and further investigated the combination of osthole and baicalin in the treatment of staphylococcal pneumonia. Using cytotoxicity assays and a mouse model of intranasal lung infection, we evaluated the effect of combined therapy. Our results suggest that the combination of osthole and baicalin alleviated S. aureus-mediated A549 cell injury and protected mice from S. aureus pneumonia.

Hepatitis C virus (HCV) infects 200 million people worldwide, and 75% of HCV cases progress into chronic infections, which consequently cause cirrhosis and hepatocellular carcinoma. HCV infection is treated with currently considered standard drugs, including direct anti-viral agents (DAAs), alone or in combination with peginterferon-α plus ribavirin. However, sustained viral responses vary in different cohorts, and high costs limit the broad use of DAAs. In this study, the ethanol and water extracts of 12 herbs from Lingnan in China were examined in terms of their inhibitory effect on HCV replication...

Renal failure and infectious disease are strongly associated with morbidity and mortality in patients with severe generalized recessive dystrophic epidermolysis bullosa (RDEB-sev gen). However, it is reportedly difficult to introduce hemodialysis with an arteriovenous fistula (AVF). We encountered a 32-year-old man with RDEB-sev gen in whom hemodialysis with a native AVF was introduced that favorably affected his long-term survival. This patient eventually died because of cachexia related to the recurrence of cutaneous squamous cell carcinoma 51 months after hemodialysis introduction...

Hypertensive disorders in pregnancy (HDP) represent some of the most important problems faced by public health because HDP is a major cause of maternal and prenatal morbidity and mortality. Several epidemiological studies have been performed to determine the prevalence and risk factors of HDP as well as its subtypes. The prevalences of HDP, gestational hypertension and preeclampsia are 5.2-8.2%, 1.8-4.4% and 0.2-9.2%, respectively. Body mass index, anemia and lower education appear to be modifiable risk factors for HDP...

B7-H1 binding to programmed death-1 may deliver a coinhibitory signal to T cells that is involved in the regulation of T-cell activation and tolerance. B7-H1 plays a key role in dysfunction of dendritic cells (DCs) during chronic HBV infection, but the expression mechanism of B7-H1 remains unclear. One hundred and twenty-nine patients with chronic HBV infection were categorized into either the immune tolerance phase (HBV-IT), the immune clearance phase (HBV-IC), or the inactive carrier phase (HBV-IA). Twenty healthy volunteers were enrolled as controls...
