Objective To investigate the association of urinary phthalate metabolites with 4 high-density lipoprotein-cholesterol(HDL-C)-related inflammatory indicators[lymphocyte/HDL-C ratio(LHR),monocyte/HDL-C ratio(MHR),neutrophil/HDL-C ratio(NHR),and platelet/HDL-C ratio(PHR)],and to explain their possible biological mechanisms.Methods The 4 573 adult participants from the National Health and Nutrition Examination Survey(NHANES)were subjected,and then generalized linear regression(GLM),restricted cubic spline(RCS),and weighted quantile sum(WQS)regressions were performed to explore the potential associations of phthalates mono-exposures and mixed exposures,respectively,with the HDL-C-related inflammation metrics.Results Nine urinary phthalate metabolites were significantly positively associated with at least 1 inflammatory marker,while 1 metabolite(MEP)showed a negative association with an inflammatory indicator(LHR).Some exposure metabolites showed a nonlinear association with outcome inflammatory indicators.WQS regression revealed varying weight contributions of individual metabolite to each inflammatory outcome.Subgroup analyses indicated differential association effects of phthalates with HDL-C-related inflammatory metrics across gender,age,and BMI populations.Conclusion There are associations between phthalate exposure and HDL-C-related inflammation indicators,but further studies are needed to reveal the underlying mechanisms.

Objective To explore the influence of combination of recombinant human collagen dressing and promestriene ointment on symptoms and vaginal microecology in patients with atrophic vaginitis.Methods The data of patients with atrophic vaginitis admitted to the General Hospital of the People's Liberation Army were retrospectively collected from April 2017 to April 2024.According to treatment methods,the enrolled patients were divided into a study group(recombinant human collagen dressing combined with promestriene ointment for 7 days)and a control group(promestriene ointment for 7 days).The efficacy,symptom disappearance time,vaginal microecology and adverse reactions were compared between groups,and recurrence rate of atrophic vaginitis within 1 month was observed.Results A total of 150 patients were screened and included,77 in the study group and 73 in the control group.After treatment,the total therapeutic efficacy in the study group was higher than that in the control group(89.61％vs.76.71％,P＜0.05).The disappearance durations of abnormal leucorrhea,vulva pruritus and vulva burning pain in the study group were significantly shorter compared with those in the control group(all P＜0.05).The vaginal pH value in the study group was lower,while the positive rate of Lactobacillus and proportions of vaginal flora density grade Ⅱ-Ⅲ and diversity grade Ⅱ-Ⅲ were higher compared to the control group(all P＜0.05).During treatment,no significant difference was exhibited in the total incidence rate of adverse reactions between the two groups(P＞0.05).The recurrence rate was lower in the study group than that in the control group within 1 month of follow-up(P＜0.05).Conclusion Recombinant human collagen dressing combined with promestriene ointment is more effective than promestriene ointment alone in improving the efficacy of patients with atrophic vaginitis,and can better shorten the disappearance durations of symptoms such as abnormal leucorrhea,vulva pruritus and vulva burning pain,correct the disorder of vaginal microecology,and reduce the short-term recurrence rate of vaginitis,and offer good safety.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

OBJECTIVE To evaluate the efficacy of sulbactam-durlobactam combined with meropenem in treating carbapenem-resistant Acinetobacter baumannii(CRAB)pulmonary infection.METHODS A total of 16 patients treated at China-Japan Friendship Hospital from Jan.1,2025 to Jun.1,2025 were included.Retrospective analy-sis was conducted on patients'basic situation,preliminary treatment regimens,infection-related diagnoses,etiolo-gy and clinical outcomes.Therapeutic drug monitoring(TDM)for sulbactam was also performed.RESULTS By the end of the treatment course,13 patients achieved etiological eradication of CRAB and clinical improvement,while 1 patient experienced CRAB recurrence within one month.Three patients showed treatment failure.TDM for sulbactam was performed in 13 patients.Except for one slightly lower,all achieved trough plasma concentra-tions above the minimum inhibitory concentration(MIC)(100％T＞MIC,MIC=4 mg/L based on clinical breakpoints).Dosage adjustments based on plasma concentrations were made for 4 patients,with 3 receiving re-duced doses and 1 receiving an increased dose.CONCLUSIONS Sulbactam-durlobactam combined with meropenem demonstrates superior efficacy in treating CRAB compared to other regimens.Under the recommended dosage,all patients can achieve the PK/PD target for sulbactam.

Objective:To compare the value of different quantification methods for intraoperative hypotension in predicting postoperative acute kidney injury (AKI) in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:The medical records of American Society of Anesthesiologists Physical Status classification Ⅲ-Ⅳ patients of either sex, aged 18-80 yr, with a body mass index of 18-30 kg/m 2, scheduled for elective OPCABG, were retrospectively collected at Tianjin Chest Hospital from September 2021 to October 2023. Intraoperative hypotension was quantified using the methods such as the number of occurrence, average decrease in magnitude, duration, and the area under the threshold (mean arterial pressure <65 mmHg, 1 mmHg = 0.133 kPa). Patients were divided into AKI group and non-AKI group based on the occurrence of AKI within 7 days postoperatively. The extended logistic regression model was used to adjust for confounding factors, and the receiver operating characteristic curves were plotted to compare the accuracy of different methods for intraoperative hypotension in predicting postoperative AKI. Results:The results of multivariate logistic regression analysis showed that the frequency of hypotension ( OR=1.03, 95% confidence interval [ CI] 1.01-1.05, P=0.010), duration of hypotension ( OR=1.04, 95% CI 1.01-1.08, P=0.007), and area under the threshold ( OR=1.03, 95% CI 1.01-1.06, P=0.023) were risk factors for postoperative AKI. The areas under the curve for the quantification methods predicting the occurrence of postoperative AKI within 7 days, including the duration of hypotension, area under the threshold, frequency of hypotension, and mean decrease in blood pressure, were 0.751, 0.652, 0.647 and 0.513, respectively. Conclusions:The duration of hypotension, area under the threshold and frequency of hypotension are independent risk factors for postoperative AKI in patients undergoing OPCABG. The duration of hypotension has a higher accuracy in predicting the occurrence of postoperative AKI.
