Objective:To discuss the inhibitory effects of combined application of chlorogenic acid(CA),procyanidin(PC),and paeoniflorin(PF),the active components of Paeoniae Radix Rubra,on Enterococcus faecalis(E.faecalis)and its biofilm,and to clarify the mechanism.Methods:The minimal inhibitory concentration(MIC)and minimal bactericidal concentration(MBC)of CA,PC,and PF against E.faecalis were detected by microdilution method;the fractional inhibitory concentration index(FICI)and fractional bactericidal concentration index(FBCI)of the three active components of Paeoniae Radix Rubra in combination were detected by checkerboard dilution method.The experiment was divided into control group,high concentration of single-drug groups(PF-10 group,PC-6 group,and CA-10 group),and drug combination groups(CA-2+PC-1 group,CA-2+PC-2 group,PF-4+PC-2 group,PF-6+PC-2 group,PF-4+CA-4 group,and PF-6+CA-4 group).Crystal violet staining was used to detect the biofilm formation of E.faecalis in various groups after treated with three active components in combination;scanning electron microscope(SEM)was used to observe the morphology of E.faecalis biofilm in various groups after treated with three active components in combination;spot assay was used to detect the inhibitory effects of three active components in combination on E.faecalis planktonic bacteria and biofilm in various groups;SEM was used to observe the damage to E.faecalis cell membrane in various groups after treated with three active components in combination;kit was used to detect the adenosine triphosphate(ATP)levels in E.faecalis planktonic bacteria and biofilm in various groups after treated with three active components in combination.Results:Among the three active components of Paeoniae Radix Rubra,the MIC of PC was 4 g·L?1 and the MBC was 6 g·L?1;the MIC of CA was 8 g·L?1 and the MBC was 10 g·L?1;the MIC and MBC of PF were both>10 g·L?1,and the concentration of PF was selected as 10 g·L?1.The combination of PC and CA showed synergistic effects,the combination of PC and PF showed additive effects,and the combination of CA and PF showed additive effects.The crystal violet staining results showed that compared with control group,the biofilm formations of E.faecalis in PF-10 group,PC-6 group,CA-10 group,and drug combination groups were significantly decreased(P<0.05);compared with PF-10 group,the biofilm formations of E.faecalis in PC-6 group,CA-10 group,CA-2+PC-1 group,CA-2+PC-2 group,PF-4+PC-2 group,PF-6+PC-2 group,and PF-6+CA-4 group were significantly decreased(P<0.05 or P<0.01).The SEM results showed that in control group,the E.faecalis biofilm was thick,with tightly connected bacteria,regular morphology,and intact cell membranes;in PF-10 group,PC-6 group,and CA-10 group,the thickness of E.faecalis biofilm was significantly reduced,and the arrangement of bacteria became relatively loose;in all drug combination groups,the E.faecalis biofilm was significantly reduced or even completely disappeared,and under high magnification,the biofilm structure was completely absent,with bacterial fragments adhering and aggregating,losing their original bacterial morphology.The spot assay results showed that compared with control group,the colonies of E.faecalis planktonic bacteria in PF-10 group,PC-6 group,and CA-10 group were significantly reduced after treated for 5,10,and 30 min,indicating gradually enhanced bactericidal effects;among drug combination groups,the combination of CA and PC significantly reduced the colonies of E.faecalis planktonic bacteria within 5 min,showing strong bactericidal effects.Compared with CA group and PC group,the colonies of E.faecalis planktonic bacteria in all drug combination groups showed no significant reduction after treated for 5,10,and 30 min;compared with control group,the colonies of E.faecalis biofilm in PF-10 group,PC-6 group,and CA-10 group were gradually decreased after the treated for 30 and 60 min,suggesting that the high concentration of single-drug groups exhibited gradually enhanced bactericidal effects on E.faecalis in biofilm.Among them,the biofilm-killing effect of PC-6 group was the most significant,with no colony formation observed after treated for 30 min;in drug combination groups,only a few colonies of E.faecalis biofilm were observed in CA-2+PC-2 group after treated for 30 min,indicating effective killing of bacteria in biofilm;compared with PC-6 group and CA-10 group,all drug combination groups achieved the bactericidal effects of high concentration of single-drug groups at low concentrations.The SEM results showed that in control group,E.faecalis exhibited an oval shape with intact cell membranes;in PF group,bacterial morphology was altered,and cell membrane integrity was damaged;in CA group,most bacterial cell membranes remained relatively intact,but the bacterial surface showed shrinkage and depression,with a few bacteria exhibiting disrupted cell membrane integrity;in PC group,the integrity of bacterial cell membranes was most severely damaged,leading to leakage of cellular contents and aggregation of cell fragments into flocculent structures;in all drug combination groups,E.faecalis exhibited ruptured cell membranes,leakage of contents,and aggregation of bacterial debris,especially in the combination of CA and PC,where the most severe disruption of bacterial cell membrane integrity and complete leakage of contents were observed;in the combination of PF and CA,bacterial surface pits and shrinkage were observed,with occasional cell membrane rupture.The kit results showed that compared with control group,the ATP levels in E.faecalis planktonic bacteria and biofilm in various groups were significantly decreased(P<0.01);compared with PF-10 group,the ATP levels in E.faecalis planktonic bacteria in CA-10 group,CA-2+PC-2 group,PF-4+CA-4 group,and PF-6+CA-4 group were significantly decreased(P<0.05 or P<0.01),and the ATP levels in E.faecalis biofilm in CA-10 group and CA-2+PC-2 group were significantly decreased(P<0.05 or P<0.01).Conclusion:The combined application of PF,PC,and CA,the active components of Paeoniae Radix Rubra,exhibits significant inhibitory effects on E.faecalis and its biofilm formation.The pairwise combinations of three active components show synergistic or additive effects,with the combination of CA and PC demonstrating the most significant synergistic effect.The underlying mechanism may be related to the disruption of E.faecalis cell membrane integrity and inhibition of bacterial ATP levels.

It is believed that all kinds of gynaecological diseases are mostly related to deficiency and stagnation of qi and blood. Medicinal insects are good at running and scurrying, with the effectiveness of activating blood circulation and dispelling blood stasis, moving qi and relieving pain, searching and dredging collaterals, attacking hardness and dissipating mass, and purging foetus and resolving mass, etc. Appropriate prescriptions can enhance the effectiveness of the formula in eliminating blood stasis and eliminating stagnation. In the treatment of menstrual disorders, chronic pelvic inflammatory disease, uterine cavity disease, incomplete miscarriage, ectopic pregnancy, and other gynaecological diseases, medicinal insects including Quanxie (Scorpio), Wugong (Scolopendra), Tubiechong (Eupolyphaga/Steleophaga), Jiuxiangchong (Coridius chinenses), Shuizhi (Hirudo), Mangchong (Tabanus), Dilong (Pheretima) and other insects for medicinal purposes could be used, and the self-prescribed empirical formulas such as Sanhuang Decoction (三黄汤), Hongteng Decoction (红藤汤), Penning Decoction (盆宁方), Shapei Decoction (杀胚方), and Gongwaiyun Decoction (宫外孕方) and so on, were all applied medicinal insects and showed effective in clinic.

Objective:To summarize the clinical features of out-of-hospital extracorporeal cardiopulmonary resuscitation(ECPR) patients and analyze the factors associated with discharge survival.Methods:The data of 54 patients with ECPR in the Emergency Center of the Second Hospital Affiliated to Zhejiang University School of Medicine from January 2020 to December 2023 were analyzed. Patients were divided into the survival group and death group based on their survival status within 30 days of discharge. Kaplan Meier method was used to draw the survival curve, and COX regression analysis was used to analyze the relevant factors of survival.Results:(1) A total of 54 patients with ECPR were included in this study. 17 (31.5%) cases were discharged alive, of which 10 (58.8%) had a good neurological prognosis, while 37 case (68.5%) died.(2) Kaplan-Meier survival analysis showed that patients who received first-witness CPR, had a lower-extremity perfusion line established, underwent IABP, achieved ROSC, had normal pH, and had an initial pupillary light reflex had a longer median survival time ( P < 0.05). (3) Univariate COX regression analysis showed that statistically differences in survival time among patients with ECMO times, hypoperfusion times, initial pupil sizes, and APACHEⅡ scores ( P < 0.05); (4) Multivariate COX regression analysis showed that APACHEⅡ score, initial pupil size, and IABP were independent predictors of survival of patients discharged from the hospital with emergency ECPR; (5) The concordance index of the COX regression model was 0.921. Conclusions:The survival model demonstrates good predictive accuracy. Healthcare professionals can use the APACHEⅡscore and initial pupil size on admission as important reference indicators to assist in determining patient prognosis, and to timely initiate IABP treatment, in conjunction with the patient’s condition, to improve the survival rate of patients discharged from the hospital.

Atrial fibrillation(AF)is the most common cardiac arrhythmia.Many medical conditions,including hypertension,diabetes,obesity,sleep apnea,and heart failure(HF),increase the risk for AF.Car-diomyocytes have unique metabolic characteristics to maintain adenosine triphosphate production.Significant changes occur in myocardial metabolism in AF.Glucagon-like peptide-1 receptor agonists(GLP-1 RAs)have been used to control blood glucose fluctuations and weight in the treatment of type 2 diabetes mellitus(T2DM)and obesity.GLP-1 RAs have also been shown to reduce oxidative stress,inflammation,autonomic nervous system modulation,and mitochondrial function.This article reviews the changes in metabolic characteristics in cardiomyocytes in AF.Although the clinical trial outcomes are unsatisfactory,the findings demonstrate that GLP-1 RAs can improve myocardial metabolism in the presence of various risk factors,lowering the incidence of AF.

Objective::To evaluate the impact of pregestational and gestational characteristics on postpartum glucose follow-up screening (PGFS) compliance in women diagnosed with gestational diabetes mellitus (GDM) in southwest China.Methods::This retrospective cohort study was conducted in West China Second Hospital, Sichuan University. Pregestational and gestational factors were extracted from hospital records and compared between women who completed PGFS and those who did not. The screening method chosen was the 75 g oral glucose tolerance test (OGTT), performed 4–12 weeks postpartum. Univariate analysis, logistic regression analysis, and Cochran-Armitage test were used to assess associations between maternal characteristics and PGFS compliance.Results::A total of 3047 women with GDM were included, with a PGFS completion rate of 47.2%. Of those who completed PGFS, 430 women (29.9%) presented abnormal results: 1.8% with impaired fasting glucose (IFG), 24.1% with impaired glucose tolerance (IGT), 2.2% with both IFG and IGT, and 1.8% with suspected diabetes. Independent factors associated with non-compliance to PGFS included higher pregestational BMI (odds ratio ( OR): 0.952; 95% confidence interval ( CI): 0.922, 0.984), multipara ( OR: 0.721; 95% CI: 0.593, 0.877), use of assisted reproduction technology (ART) ( OR: 1.427; 95% CI: 1.080, 1.885), excessive gestational weight gain ( OR: 0.956; 95% CI: 0.936, 0.977), elevated fasting plasma glucose (FPG) prior to delivery ( OR: 0.909; 95% CI: 0.835, 0.988), and undergoing cesarean section ( OR: 1.232; 95% CI: 1.017, 1.492). PGFS completion rates significantly decreased with increasing pregestational BMI and earlier gestational age ( P < 0.001). Conclusion::Establishing dedicated postpartum follow-up teams and targeting women with higher pregestational BMI, multiparity, ART use, excessive gestational weight gain, elevated pre-delivery FPG, and those undergoing cesarean section are critical to improving postpartum GDM management.
