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.

ObjectiveTo evaluate the supportive policies for caregivers issued in China, and analyze the structures and contents. MethodsThe national supportive policies for family caregivers in China within the past decade were text-mined using ROSTCM 6.0. Secondary indicators were established according to the Policy Modeling Consistency (PMC) index model combining with World Health Organization six blocks of health services. ResultsThe average PMC score was 7.38. There were seven good policies and three accepted policies. The policies covered well in publicity, recipients and functions, and needed to improve in incentive and restraint. ConclusionChina's policies have played a positive role in supporting family caregivers. It is needed to reduce the burden on family caregivers and improve their welfare.

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.

Objective To investigate the regulatory effect of Jianpi Huayu Prescription(Ginseng Radix et Rhizoma,Poria,Atractylodis Macrocephalae Rhizoma,Salviae Miltiorrhizae Radix et Rhizoma,etc.)on epithelial-mesenchymal transition(EMT)and angiogenesis of hepatocellular carcinoma through TGF-β1/Smad7 pathway.Methods(1)Hep3B tumor-bearing mouse model was established by BALB/C-nu nude mice.The mice were randomly divided into control group and Jianpi Huayu Prescription low-,medium-and high-dose groups(3.844,7.689,15.378 g·kg-1·d-1),with five mice in each group.Intragastric administration was performed once a day for 21 days.(2)Hep3B cells were divided into blank group,model group(10 ng·mL-1 TGF-β1),low-concentration group(10 ng·mL-1 TGF-β1+4 mg·mL-1 Jianpi Huayu Prescription),and high-concentration group(10 ng·mL-1 TGF-β1+6 mg·mL-1 Jianpi Huayu Prescription).After 48 hours of TGF-β1 induction,the cells were replaced with the corresponding concentration of Jianpi Huayu Prescription complete culture medium(0,4,6 mg·mL-1)and cultured for 24 hours.(3)HUVEC cells were divided into normal group,model group,Chinese medicine group,model plus Chinese medicine group.The cells in the normal group were cultured with conditioned medium without TGF-β1;the cells in the model group were cultured with conditioned medium containing TGF-β1.The cells in the Chinese medicine group were cultured in conditioned medium containing 4 mg·mL-1 Jianpi Huayu Prescription without TGF-β 1.The cells in the model plus Chinese medicine group were cultured with conditioned medium containing 4 mg·mL-1 Jianpi Huayu Prescription and TGF-β1.After 24 hours of continuous culture,the cells were collected for subsequent experiments.(4)The tumor mass index and tumor inhibition rate of subcutaneous transplantation tumor of Hep3B tumor-bearing nude mice were calculated.The expression of CD31 in subcutaneous xenografts of tumor-bearing nude mice was detected by immunofluorescence.The microvessel density of subcutaneous transplanted tumor in nude mice was detected by immunohistochemistry.The migration ability of Hep3B cells was detected by cell scratch test.Transwell assay was used to detect the invasion ability of Hep3B/HUVEC cells.The tube formation ability of HUVEC cells was detected.The expression levels of related proteins in subcutaneous transplanted tumors,Hep3B and HUVEC cells of tumor-bearing nude mice were detected by Western Blot.Results(1)Compared with the control group,the weight and tumor mass index of subcutaneous transplanted tumor in nude mice in the medium-and high-dose groups of Jianpi Huayu Prescription were significantly decreased(P＜0.01).The expression of CD31 and microvessel density in subcutaneous transplanted tumors of nude mice in low-,medium-and high-dose groups were significantly decreased(P＜0.05,P＜0.01),the protein expressions of VE-cadherin,EphA2 and N-cadherin were significantly down-regulated(P＜0.05,P＜0.01),and the protein expressions of E-cadherin and Smad7 was significantly up-regulated(P＜0.01).(2)Compared with the blank group,the relative migration rate of Hep3B cells in the model group was significantly increased(P＜0.05),and the number of invasive cells was significantly increased(P＜0.01).The protein expressions of Vimentin and N-cadherin were significantly up-regulated(P＜0.01),and the protein expressions of E-cadherin and Smad7 was significantly down-regulated(P＜0.01).Compared with the model group,the relative migration rate of Hep3B cells in the low-and high-concentration groups of Jianpi Huayu Prescription was significantly decreased(P＜0.01),and the number of invasive cells was significantly decreased(P＜0.01).The protein expressions of Vimentin and N-cadherin was significantly down-regulated(P＜0.01),and the protein expressions of E-cadherin and Smad7 were significantly up-regulated(P＜0.01).(3)Compared with the normal group,the number of tubular branching points formed by HUVEC cells in the model group was significantly increased(P＜0.01),the length of tubular branching was significantly increased(P＜0.01),and the number of invasive cells was significantly increased(P＜0.01).The protein expressions of VE-cadherin and EphA2 were significantly up-regulated(P＜0.01),and the protein expression of Smad7 was significantly down-regulated(P＜0.01).Compared with the model group,the number of tubular branching points formed by HUVEC cells in the model plus Chinese medicine group was significantly reduced(P＜0.01),the length of tubular branching was significantly shortened(P＜0.01),and the number of invasive cells was significantly reduced(P＜0.01).The protein expressions of VE-cadherin and EphA2 were significantly down-regulated(P＜0.01),and the protein expression of Smad7 was significantly up-regulated(P＜0.01).Conclusion Jianpi Huayu Prescription can significantly inhibit the growth,invasion and migration of hepatocellular carcinoma,which may be related to the regulation of EMT and angiogenesis mediated by TGF-β1/Smad7 pathway.

Objective:To explore the mechanisms of Qianlie Jindan Tablets(QLJD)acting on chronic nonbacterial prostatitis(CNP)in rats based on non-targeted urine metabolomics.Methods:According to the body mass index,we equally randomized 30 eight-week-old male SD rats into a blank control,a CNP model control and a QLJD medication group.We established the CNP model in the latter groups and,from the 4th day of modeling,treated the rats in the blank and model control groups intragastrically with nor-mal saline and those in the QLJD medication group with QLJD suspension,qd,for 30 successive days.Then we detected the changes in the metabolites of the rats by ultra-high-performance liquid chromatography-tandem mass spectrometry,and identified the differential metabolites in different groups by multivariate statistical analysis,followed by functional annotation of the differential metabolites.Results:Eight common metabolites were identified by metabolomics analysis,of which 5 were decreased in the CNP model controls and increased in the QLJD medication group,while the other 3 increased in the former and decreased in the latter group.Creatinine and genistein were important differential metabolites,and the arginine and proline metabolic pathways and isoflavone biosynthesis pathways were the main ones for QLJD acting on CNP.Compared with the blank controls,the model controls showed up-regulated arginine and proline metabolic pathways,increased production of creatinine,down-regulated isoflavone biosynthetic pathway and decreased produc-tion of genistein.The above changes in the model controls were all reversed in the QLJD medication group.Conclusion:QLJD acts effectively on CNP in male rats by regulating L-arginine and proline metabolic pathways,as well as the isoflavone biosynthesis pathway and naringenin metabolism.

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.
