ObjectiveTo study on the different therapeutic effects and potential mechanisms of Rhei Radix et Rhizoma（RH） before and after steaming with wine on constipation model mice. MethodsFifty-four male ICR mice were randomly divided into control group， model group， lactulose group（1.5 mg·kg^-1）， high， medium and low dose groups of RH and RH steaming with wine（PRH）（8， 4， 1 g·kg^-1）. Except for the control group， the constipation model was replicated by gavage of loperamide hydrochloride（6 mg·kg^-1） in the other groups. After 2 weeks of modeling， each administration group was gavaged with the corresponding dose of drug solution， and the control and model groups were given an equal volume of normal saline， 1 time/d for 2 consecutive weeks. After administration， the feces were collected for 16S rRNA sequencing， the levels of gastrin（GAS）， motilin（MTL）， interleukin-6（IL-6）， γ-interferon（IFN-γ） in the colonic tissue were detected by enzyme-linked immunosorbent assay（ELISA）， the histopathological changes of colon were observed by hematoxylin-eosin（HE） staining， flow cytometry was used to detect the proportion changes of CD4⁺， CD8⁺ and regulatory T cell（Treg） in peripheral blood. ResultsCompared with the control group， the model group showed significantly decrease in fecal number in 24 h， fecal quality and fecal water rate（P<0.01）， the colon was seen to have necrotic shedding of mucosal epithelium， localized intestinal glands in the lamina propria were degenerated， necrotic and atrophied， a few lymphocytes were seen to infiltrate in the necrotic area in a scattered manner， the contents of GAS and MTL， the proportions of CD4⁺， CD8⁺ and Treg were significantly reduced（P<0.01）， the contents of IL-6 and IFN-γ were significantly elevated（P<0.05， P<0.01）. Compared with the model group， the fecal number in 24 h， fecal quality and fecal water rate of high-dose groups of RH and PRH were significantly increased（P<0.05， P<0.01）， the pathological damage of the colon was alleviated to varying degrees， the contents of GAS， MTL， IL-6 and IFN-γ were significantly regressed（P<0.05， P<0.01）， and the proportions of CD4⁺ and CD8⁺ were significantly increased（P<0.01）， although the proportion of Treg showed an upward trend， there was no significant difference. In addition， the results of intestinal flora showed that the number of amplicon sequence variant（ASV） and Alpha diversity were decreased in the model group compared with the control group， and there was a significant difference in Beta diversity， with a decrease in the relative abundance of Lactobacillus and an increase in the relative abundances of Bacillus and Helicobacter. Compared with the model group， the ASV number and Alpha diversity were increased in the high-dose groups of RH and PRH， and there was a trend of regression of Beta diversity to the control group， the relative abundance of Lactobacillus increased， and the relative abundances of Bacillus and Helicobacter decreased. ConclusionRH and PRH can improve dysbacteriosis， promote immune system activation， inhibit the release of inflammatory factors for enhancing the gastrointestinal function， which may be one of the potential mechanisms of their therapeutic effect on constipation.

BACKGROUND: The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined. METHODS: All CTO vessels treated with successful anatomical PCI in patients from PANDA III trial were retrospectively measured for post-PCI QFR. The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs, composite of target vessel-related cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization). Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs, and all vessels were stratified by this optimal cutoff value. Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI. RESULTS: Among 428 CTO vessels treated with PCI, 353 vessels (82.5%) were analyzable for post-PCI QFR. 31 VOCEs (8.7%) occurred at 2 years. Mean value of post-PCI QFR was 0.92 ± 0.13. Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91. The incidence of 2-year VOCEs in the vessel with post-PCI QFR < 0.91 (n = 91) was significantly higher compared with the vessels with post-PCI QFR ≥ 0.91 (n = 262) (22.0% vs. 4.2%, HR = 4.98, 95% CI: 2.32-10.70). CONCLUSIONS Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO. Achieving functionally optimal PCI results (post-PCI QFR value ≥ 0.91) tends to get better prognosis for patients with CTO lesions.

Objective:To investigate the 10-year incidence of reproductive system malignancies and their associated risk factors among overweight and obese women with different metabolic phenotypes aged 40 years and older in Guiyang City.Methods:A total of 6 444 female residents in Yunyan District, Guiyang City were included from the 2011 " Epidemiological Study on the Risk of Malignancy in Chinese Patients with Type 2 Diabetes Mellitus(REACTION)". Based on body mass index(BMI) and the presence or absence of metabolic syndrome(MetS), participants were categorized into four groups: metabolically healthy normal weight(MHNW, n=2 373), metabolically unhealthy normal weight(MUNW, n=1 098), metabolically healthy overweight/obese(MHO, n=2 229), and metabolically unhealthy overweight/obese(MUO, n=744). Baseline data were collected, and participants were followed up for 10 years to document the incidence of female reproductive system malignancies, including breast cancer, ovarian cancer, cervical cancer, and endometrial cancer. Logistic regression models were used to evaluate the association between metabolic phenotype and the 10-year risk of developing reproductive system malignancies. Results:Over a mean follow-up period of (9.89±0.77) years, the overall incidence of reproductive system malignancies was 1.15%(74/6, 444). Baseline characteristics such as age, BMI, high-density lipoprotein-cholesterol(HDL-C), and triglycerides(TG) differed significantly among the groups( P<0.05). The cumulative incidence of reproductive system malignancies in each group was: MHNW 0.93%(22/2 373), MUNW 0.73%(8/1 098), MHO 1.57%(35/2 229), and MUO 1.21%(9/744). There were no statistically significant differences in incidence across the four groups( P>0.05). However, multivariable logistic regression analysis revealed that, compared with the MHNW group, the adjusted HR (95% CI) were: MUNW 0.787(0.349-1.774, P>0.05), MHO 4.835(1.708-13.688, P<0.05), and MUO 3.719(1.144-12.089, P<0.05). Conclusion:Overweight and obesity are significant risk factors for reproductive system malignancies in women aged 40 and above. The presence of metabolic abnormalities in overweight or obese women further increases the risk of developing such malignancies.

Objective To establish a method for chiral analysis of dextromethorphan and levomethorphan in hair and urine by high performance liquid chromatography-triple quadrupole mass spectrometry.Methods Hair samples were extracted by grinding ultrasound,and urine samples were extracted by acetonitrile.The supernatant were separated using a Astec CHIROBIOTIC? V2 column(25 cm × 4.6 mm,5 μm)with 0.5 ‰ formic acid and 10 mmol/L ammonium acetate-methanol as mobile phases,then analyzed in scheduled-multiple reaction monitoring mode.Results The limits of detection and lower limits of quantitation of dextromethorphan and levomethorphan were 0.001 ng/mg and 0.005 ng/mg in hair samples,while they were 0.050 ng/mL and 0.200 ng/mL in urine samples.In the corresponding concentration range,there were good linearity for chiral isomers with correlation coefficients over 0.999.Besides,the recovery rates,accuracy and precision met analytical requirements,and no significant matrix effect were exhibited.In the actual case samples,dextromethorphan were detected in hair of 12 cases and in the corresponding urine of 3 cases.Conclusion This method is rapid,sensitive and reliable for chiral analysis of dextromethorphan and levomethorphan in hair and urine.

Objective:To investigate the trends of pathogen distribution and drug resistance in elderly patients with stroke-associated pneumonia(SAP)in China,providing references for clinical antibiotic selection and application.Methods:A meta-analysis was conducted to comprehensively evaluate changes in resistance rates of major pathogens isolated from elderly SAP patients to key clinical antibiotics over the past 10 years.The trends of antimicrobial resistance were analyzed.Results:A total of 12 qualified articles were screened out,involving 1 202 cases of pulmonary infections and 1 315 pathogenic isolates.Gram-negative bacilli accounted for 951 strains(72.32%),Gram-positive cocci for 278 strains(21.14%),and fungi for 86 strains(6.54%).The top five pathogens were Klebsiella pneumoniae,Pseudomonas aeruginosa,Acinetobacter Baumannii,Staphylococcus aureus and Escherichia coli.The resistance rates to various antibiotics showed minor fluctuations across years.Conclusions:Gram-negative bacilli dominate pulmonary infections in elderly stroke patients,with a high proportion of multidrug-resistant strains.Strengthened pathogen surveillance and rational antibiotic use are critical in clinical practice.

Objective To investigate the expression of ferritinophagy-related gene ELAV-like RNA binding protein 1(ELAVL1)in multiple myeloma(MM)and elucidate its diagnostic and prognostic value for MM.Methods First,we analyzed ELAVL1 expression level in healthy controls and MM patients using data from the GEO and TCGA databases.Subsequently,bone marrow specimens were collected from 28 newly diagnosed MM patients and 20 healthy controls,and qRT-PCR was employed to validate ELAVL1 expression.The diagnostic and prognostic potential of ELAVL1 was assessed using ROC curve analysis and Kaplan-Meier survival curves.Additionally,univariate and multivariate COX regression analyses were performed to identify independent risk factors for MM prognosis.Finally,KEGG and GO enrichment analyses were performed using the DAVID online platform.Results The level of ELAVL1 expression was significantly higher in newly diagnosed MM patients and refractory/relapsed MM patients than in the healthy controls(P＜0.001).Moreover,ELAVL1 expression was positively correlated with the International Staging System(ISS)stage of MM(P＜0.01).Furthermore,qRT-PCR validation confirmed that ELAVL1 expression was elevated in the 28 newly diagnosed MM patients compared to the 20 healthy controls(P＜0.001).ROC curve analysis demonstrated that ELAVL1 could effectively differentiate between newly diagnosed MM patients,healthy controls,and MGUS patients(P＜0.001 and P=0.000 2,respectively).Survival analysis revealed that high ELAVL1 expression was associated with shorter progression-free survival(P=0.0141)and overall survival(P=0.008 0).Univariate and multivariate COX regression analyses identified high ELAVL1 expression as an independent risk factor for poor MM prognosis(P=0.005 0).KEGG analysis suggested that ELAVL1 might be involved in the Hippo and MAPK signaling pathways.Conclusion High ELAVL1 expression in MM may serve as a biomarker for diagnosis and poor prognosis.ELAVL1 may promote MM initiation and progression via the Hippo and MAPK signaling pathways.
