OBJECTIVETo observe the effects of low-dose exogenous estrogen nonylphenol (NP) on the proliferation of human prostate cancer cell lines DU-145 and the expression of the membrane estrogen receptor GPR30 in the DU-145 cells.

METHODSWe exposed DU-145 cells to different concentrations of NP for 24 hours, followed by measurement of the half maximal inhibitory concentration (IC50) of the cells by cell proliferation assay and determination of the concentration of exposure to low-dose NP. We also observed the expressions of 3 estrogen receptors (ER), including ER-alpha, ER-beta and membrane estrogen receptor GPR30, in the DU-145 cells exposed to low-dose NP by RT-PCR.

RESULTSCell proliferation assay showed that within a certain range of doses, NP inhibited the proliferation of the DU-145 cells with an IC50 of 46 micromol/L, a much lower dose of NP than IC50, 0.01, 0.1.1 micromol/l NP, that can promote the proliferation of DU-145 cells. The results of RT-PCR indicated that the expressions of the three ERs in the DU-145 cells were similar to those in prostate epithelial cells, and that low-dose NP promoted the expression of GPR30.

CONCLUSIONMembrane estrogen receptor GPR30 may play a role in low-dose NP promoting the proliferation of DU-145 cells.

Objective To study the effect of hyperbaric oxygen (HBO) therapy on perihematomal edema in acute spontaneous intracerebral hemorrhage. Methods Sixty-three consecutive hospitalized patients with supraten-torial intracerebral hemorrhage were allocated to an HBO group (n = 30) or a control group (n = 33) at random. Routine therapies were used with both groups. The treatment group received in addition twenty consecutive daily ses-sions of HBO therapy beginning 3～5 d after onset. MRI brain scans were performed on the 5～7th and 25th day. Absolute edema volumes and relative edema volumes were measured from T2-weighted images. Apparent diffusion co-efficients (ADCs) of the edematous regions were calculated on diffusion-weighted images (DWI). Results There were no statistical differences between the two groups in terms of age, sex, blood pressure, NIHSS, hematoma posi-tion or volume. At the 5th～7th d, both absolute and relative edema volumes in the HBO group were smaller than in the controls (P≤0.05). Brain edema was still prominent at the 25th d. Absolute edema volumes, relative edema volumes and ADC values were all smaller in the HBO group at the 25th day compared with the controls (P≤0.05). Conclusion HBO therapy soon after intracerebral hemorrhage can lessen the severity and range of brain edema. E-dema persists after the onset of the disease, and HBO can reduce such delayed brain edema. HBO may benefit func-tional recovery from intracerebral hemorrhage by reducing perihematomal edema.

The exploration of drug toxicity and mechanisms is a vital component in ensuring the safe use of drugs in clinical practice, as this topic has attracted widespread concern. The intestinal flora holds great significance for drug metabolism, efficacy and mechanism, and is an instrumental metabolic organ that facilitates material information transfer and biotransformation. However, an increasing number of studies have shown that intestinal bacteria are closely related to the toxicity of specific drugs. On the one hand, drugs are transformed into toxic metabolites under the influence of intestinal bacteria, thus inducing direct drug toxicity. On the other hand, the composition and function of the intestinal flora are altered under drug influence, resulting in disruption of endogenous metabolic pathways. Consequently, this disruption compromises the intestinal barrier and affects other organs, leading to indirect drug toxicity. This review meticulously compiles recent examples of drug toxicity attributed to intestinal bacteria, explores in depth the contention that metabolic enzymes of gut microbiota may be of great influence on oral drug toxicity, and outlines prospective avenues for future research on gut microbiota and drug toxicity and mechanisms. This not only provides novel perspectives for the judicious clinical utilization of drugs but also offers insights for the safety assessment of innovative pharmaceuticals.
