Benign prostatic hyperplasia (BPH) is one of the most common diseases in elderly men, the incidence of which gradually increases with age and leads to lower urinary tract symptoms (LUTS), which seriously affects the quality of life of patients. Chinese herbal medicines (CHMs) are widely used for the treatment of BPH in China and some other countries. To explore the molecular mechanisms of CHMs for BPH, we conducted a review based on peer-reviewed English-language publications in PubMed and Web of Science databases from inception to December 31, 2023. This article primarily reviewed 32 papers on the use of CHMs and its active compounds in the treatment of BPH, covering animal and cell experiments, and identified relevant mechanisms of action. The results suggest that the mechanisms of action of CHMs in treating BPH may involve the regulation of sex hormones, downregulation of cell growth factors, anti-inflammatory and antioxidative effects, inhibition of cell proliferation, and promotion of apoptosis. CHMs also exhibit α-blocker-like effects, with the potential to relax urethral smooth muscle and alleviate LUTS. Additionally, we also reviewed 4 clinical trials and meta-analyses of CHMs for the treatment of BPH patients, which provided initial evidence of the safety and effectiveness of CHMs treatment. CHMs treatment for BPH shows advantages as a multi-component, multi-target, and multi-pathway therapy, which can mitigate the severity of the disease, improve LUTS, and may become a reliable treatment option in the future.

Objective:To study the alveolar bone remodeling of maxillary anterior teeth after extraction treatment and 2-year recovery period in adolescent patients with maxillary anterior arch protrusion.Methods:15 adolescent patients with maxillary anterior arch protru-sion were included,2 maxillary first premolars were extracted and implant anchorage combined with sliding method were used to close the extraction gap.CBCT images were taken before treatment(T0),after treatment(T1)and 2 years of recorvery period(T2),respectively.After multi-plane reconstruction with Dophin Imaging,the alveolar bone area(ABA)changes of maxillary central incisor,lateral incisor and canine at cementoenamel junction(CEJ-3 mm),root neck,central part,and root tip were measured and recorded as TAC,TA1,TA2 and TA3 respectively.The labial palatal alveolar crest to CEJ bone height(BH)of each tooth was recorded as BCL,BCP respectively.The data were analyzed by IBM SPSS statistics 25.0.Results:In T0-T2 phase,TA1 of each tooth was reduced.In T0-T1 phase,the horizontal adsorption of teeth was significantly correlated with ΔBCP,followed by ΔTA3.In T0-T2 phase,ΔBCP,ΔTA2,ΔTA3 and the horizontal adsorption of teeth showed low negative correlation.In T0-T1 phase,the vertical reduction of teeth was significantly positively correlated with ΔTAC,followed by low correlation with ΔTA3 and ΔTA1.Conclusion:In the treatment of anterior arch protrusion after extraction correction in adolescent patients the more the vertical reduction and horizontal adsorption of teeth in the treatment phase,the more the alveolar bone thickness and height around the tooth root in the maintenance phase,which were significantly positively correlated.Reasonable control of the vertical move-ment of teeth in the alveolar bone can improve the periodontal condition around the teeth to a certain extent.

ObjectiveTo investigate the effect of Shugan Quyu Jiedu prescription (SGQYJDF) on inducing ferroptosis in hepatocellular carcinoma cells based on the tumor protein 53 (p53)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) pathway. MethodMHCC97H cells were divided into the blank serum group (10% blank serum medium), SGQYJDF-containing serum low concentration group (5% SGQYJDF-containing serum and 5% blank serum medium), SGQYJDF-containing serum medium concentration group (7.5% SGQYJDF-containing serum and 2.5% blank serum medium), SGQYJDF-containing serum high concentration group (10% SGQYJDF-containing serum medium) and sorafenib group (sorafenib concentration of 10 μmol·L-1 in 10% blank serum medium). After 24 hours of intervention, the cell survival rate was detected by cell counting kit-8 (CCK-8) assay. The cell proliferation ability was detected by 5-ethynyl-2′-deoxyuridine (EdU) staining. The intracellular ferrous ion (Fe2+) level was detected by ferrous ion fluorescent probe (FerroOrange) staining. The intracellular malondialdehyde (MDA) and glutathione (GSH) levels were detected by colorimetric assays. The ultrastructure of mitochondria was observed by transmission electron microscopy. The expression levels of ferroptosis-related proteins p53, SLC7A11 and GPX4 were detected by Western blot. ResultIn terms of cell viability, compared with the blank serum group, the SGQYJDF group showed a dose-dependent decrease in the survival rate of MHCC97H cells. Effect of the medium and high concentrations of SGQYJDF on the survival rate of MHCC97H cells were significantly decreased (P<0.01). Additionally, the results of the EdU assay showed that both the medium and high concentrations of SGQYJDF were able to inhibit the proliferation ability of MHCC97H cells (P<0.05, P<0.01). Regarding the biochemical indicators of ferroptosis, compared to the blank serum group, the medium and high concentrations of SGQYJDF were able to dose-dependently increase the intracellular Fe2+ level (P<0.01). The low, medium, and high concentrations of SGQYJDF were able to dose-dependently decrease the level of GSH in MHCC97H cells (P<0.01) and increase the level of MDA in the cells (P<0.05, P<0.01). In terms of pathway-related protein expression, compared to the blank serum group, the medium and high concentrations of SGQYJDF could significantly increase the expression of p53 (P<0.01). The low, medium, and high concentrations of SGQYJDF could significantly decrease the expression of GPX4 (P<0.01). The high concentration of SGQYJDF could decrease the expression of SLC7A11 (P<0.01). In terms of the cell morphology of ferroptosis, compared with the blank serum group, transmission electron microscopy revealed that the low concentration of SGQYJDF caused mitochondrial deformation, while the medium and high concentrations of SGQYJDF resulted in reduced mitochondrial volume, increased double-layer membrane density, and decreased mitochondrial cristae. These features were similar to those of sorafenib-induced ferroptosis. Furthermore, compared with the sorafenib group, the high concentration of SGQYJDF showed no statistically significant differences in cell survival rate, proliferation ability, Fe2+ level, MDA level, and GSH level. ConclusionThe results suggest that SGQYJDF may induce ferroptosis and inhibit proliferation in hepatocellular carcinoma MHCC97H cells by upregulating the expression of p53, suppressing the expressions of GPX4 and SLC7A11, downregulating the level of GSH, and leading to the accumulation of intracellular Fe2+ and MDA.

One patient was admitted to a hospital due to"sepsis,chronic kidney disease,type 2 diabetes,shock,and cerebral infarction".Patient's blood specimen was taken for clinical examination.Aerobic and anaerobic culture results of catheter blood and venous blood were both positive.The pathogen was identified as Staphylococcus pas-teuri by VITEK MS,and the patient was diagnosed as catheter-related bloodstream infection caused by Staphylo-coccus pasteuri.Clinical empirical use of piperacillin for anti-infection treatment was ineffective,and vancomycin was eventually used for treatment based on in vitro antimicrobial susceptibility testing.Patient's condition improved after removing the venous catheter.There are currently no reported cases of Staphylococcus pasteuri in China.Ear-ly identification of pathogen and adjustment of treatment plans based on antimicrobial susceptibility testing results are crucial for effective treatment of this case.
