ObjectiveTo evaluate the clinical efficacy and safety of the traditional Chinese medicine （TCM） compound Chaiqin Xiaoyong Decoction （柴芩消痈饮， CXD） combined with Jinhuang Ointment （金黄膏， JO） in treating the nodular stage of acne mastitis of liver meridian heat accumulation type. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 108 patients with liver meridian heat accumulation type acne mastitis in the nodular stage were randomly assigned to a treatment group and a control group， with 54 patients in each group. Both groups received topical application of JO once daily at a thickness of 3~5 mm for 8 hours， along with standard nursing care. On this basis， the treatment group received oral CXD granules， while the control group received placebo granules， administered twice daily， 3 sachets per dose， for 14 consecutive days. Clinical efficacy， TCM symptom scores， nodule size， visual analogue scale （VAS） pain scores， white blood cell （WBC） count， C-reactive protein （CRP） level， and systemic immune-inflammation index （SII） were compared. At the end of treatment， efficacy and safety indicators were evaluated. A 6-month follow-up was conducted to compare the proportion of patients undergoing surgical treatment. ResultsThe total clinical efficacy rate in the treatment group was 90.38% （47/52）， significantly higher than 32.00% （16/50） in the control group （P＜0.01）. The treatment group also showed significantly lower TCM symptom scores， VAS scores， nodule size， WBC count， CRP level， and SII （P＜0.05 or P＜0.01）. During follow-up， the surgical intervention rate in the treatment group was 5.77% （3/52）， lower than 14.00% （7/50） in the control group， with a statistically significant difference （P＜0.01）. No significant abnormalities were observed in safety indicators before and after treatment in either group. ConclusionCXD effectively reduces nodule size and alleviates symptoms such as redness and pain in patients with acne mastitis of liver meridian heat accumulation type， improves TCM symptom scores， enhances overall clinical efficacy， and demonstrates good safety.

Objective: To explore the diagnosis, treatment and prognosis of primary prostatic signet ring cell carcinoma (SRCC), so as to provide reference for the clinical diagnosis and treatment. Methods: A retrospective analysis was conducted on the clinical data of 6 patients with primary prostatic SRCC treated in Nanjing Drum Tower Hospital during Nov.2020 and Sep.2024.The clinical manifestations, imaging features, treatment methods, histological characteristics and prognosis were summarized. Results: The average age of the patients was (72.00±4.28) years.Varying degrees of dysuria occurred in 4 patients. All patients underwent multi-parametric magnetic resonance imaging (mpMRI) examination before surgery, and the results indicated typical prostate cancer.Preoperative biopsies showed high-grade (Gleason 8-10) prostate acinar adenocarcinoma.Postoperative pathological diagnoses were mixed types of prostate acinar adenocarcinoma and SRCC, and no metastasis was found in the pelvic lymph nodes.All patients were followed up for 1 to 46 months after surgery and are currently alive.Robot-assisted laparoscopic radical prostatectomy only was performed in 3 cases; apalutamide and leuprolide/triptorelin was administered after surgery in 2 cases; bicalutamide + goserelin was administered after surgery in 1 case, who developed bladder metastasis of prostate cancer 24 months later, and the serum prostate-specific antigen (PSA) concentration decreased to a safe level (<0.2 ng/mL) after the use of darolutamide with radiotherapy.No recurrence or metastasis was found in the remaining patients. Conclusion: Primary prostatic SRCC is a rare and highly aggressive malignant tumor of the prostate.The diagnosis depends on pathological examinations due to lack of specific imaging features and clinical manifestations.The prognosis is poor, and there is currently no standardized treatment.The combined use of surgery, hormonotherapy and radiotherapy can help improve the survival rate of patients.

OBJECTIVE To establish a multi-dimensional value assessment framework for new antidiabetic drugs based on multi-criteria decision analysis theory， thus providing a theoretical framework and methodology for evidence-informed medical insurance decision-making. METHODS Firstly， multi-dimensional evidence was searched and obtained to provide reliable data for the establishment of the framework. Secondly， in terms of the obtained evidence， the value assessment framework was preliminarily constructed. Its structure， main core criteria， and contextual criteria were determined through focus group discussion. Finally， the criteria and sub-criteria of the framework and their weights were further determined， reasons for inclusion of sub-criteria and the reasonableness of rating scores were evaluated， and methods of assessment were optimized through expert consultation. RESULTS The multi-dimensional value assessment framework for new antidiabetic drugs was composed of core criteria and contextualized criteria， which could be used for quantitative and qualitative value assessment of new drugs， respectively. The core criteria consisted of five dimensions， with affordability （6.31） having the highest weighting score， followed by comparative effectiveness （6.20）， comparative safety （6.01）， cost-effectiveness （5.89）， and quality of evidence （5.46）. After the normalization of weight within sub-criteria， the budget impact on medical insurance had the highest standardized weight， followed by the control of glycated hemoglobin and patient affordability. The contextual criteria included two dimensions， i. e.， innovation and equity. CONCLUSIONS The assessment framework integrates evidence， stakeholders’ values， and decision contexts to enable a multi- dimensional and evidence-based assessment of the value of new antidiabetic drugs.

Objective: To investigate the molecular regulatory mechanism of hypoxia-inducible factor-1α (HIF-1α) in mechanical stress-induced inflammatory cytokine expression in human periodontal ligament cells (hPDLCs), providing a theoretical basis and potential therapeutic target for inflammatory control during orthodontic treatment. Methods: This study was approved by the Institutional Ethics Committee. Primary human periodontal ligament cells (hPDLCs) were isolated and cultured in vitro. Self-renewal capacity was confirmed via colony-forming assays, while osteogenic and adipogenic differentiation potential was evaluated via Alizarin Red S staining, alkaline phosphatase (ALP) activity assays, and Oil Red O staining. An in vitro compressive force stimulation model (1.5 g/cm2, 12 h) was established to compare inflammatory cytokine expression of hPDLCs—interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and HIF-1α—between the Control group (no mechanical stimulation) and the Force group (1.5 g/cm2, 12 h) using quantitative real-time PCR (qRT-PCR), Western blot, and immunofluorescence (IF) staining. Mechanically induced HIF-1α-regulated gene expression changes were analyzed through transcriptomic sequencing. To explore pharmacological inhibition, the small-molecule HIF-1α inhibitor LW-6 was applied at varying concentrations (10 μmol/L, 30 μmol/L, 50 μmol/L) to optimize the treatment dose. Subsequently, qRT-PCR, Western blot, and IF staining were conducted to evaluate inflammatory cytokine of hPDLCs and HIF-1α expression in three groups: Control (no force), Force (1.5 g/cm2, 12 h), and Force+LW6 (1.5 g/cm2, 12 h + 30 μmol/L LW-6). Results: Primary hPDLCs demonstrated self-renewal capacity along with osteogenic and adipogenic differentiation potential. Compared to the Control group, the Force group exhibited significantly increased mRNA and protein expression levels of inflammatory cytokines IL-1β, IL-6, and TNF-α, along with enhanced fluorescence intensity of IL-1β and TNF-α. Transcriptomic analysis revealed that mechanical compressive force activated the HIF-1 signaling pathway, which subsequently mediated inflammatory responses and bone remodeling processes in hPDLCs. Furthermore, the mRNA and protein levels of HIF-1α were considerably elevated in the Force group compared to the Control group. Treatment with LW-6 (10, 30, or 50 μmol/L) effectively suppressed HIF-1α expression, with 30 μmol/L LW-6 identified as the optimal concentration for intervention. In subsequent experiments, the Force group showed significant upregulation in mRNA/protein expression of IL-1β, IL-6, and TNF-α compared to the Control group, as well as intensified HIF-1α, IL-1β, and TNF-α fluorescence signals. Conversely, the Force+LW6 group (mechanical force + 30 μmol/L LW-6) exhibited a notable reduction in inflammatory cytokine expression levels and a weakening of HIF-1α, IL-1β, and TNF-α fluorescence signals compared to the Force group. Conclusion HIF-1α potentiates mechanical stress-induced inflammatory responses in hPDLCs and may serve as a promising therapeutic target for mitigating orthodontic-associated periodontal inflammation.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To explore the optimal pulse oxygen saturation (SpO 2) range during hospitalization for patients with sepsis. Methods:A case-control study design was employed. Demographic information, vital signs, comorbidities, laboratory parameters, critical illness scores, clinical treatment information, and clinical outcomes of sepsis patients were extracted from the Medical Information Mart for Intensive Care-Ⅳ (MIMIC-Ⅳ). A generalized additive model (GAM) combined with a Loess smoothing function was employed to analyze and visualize the nonlinear relationship between SpO 2 levels during hospitalization and in-hospital all-cause mortality. The optimal range of SpO 2 was determined, and Logistic regression model along with Kaplan-Meier curve were utilized to validate the association between the determined range of SpO 2 and in-hospital all-cause mortality. Results:A total of 5?937 patients met the inclusion criteria, among whom 1?191 (20.1%) died during hospitalization. GAM analysis revealed a nonlinear and U-shaped relationship between SpO 2 levels and in-hospital all-cause mortality among sepsis patients during hospitalization. Multivariable Logistic regression analysis further confirmed that patients with SpO 2 levels between 0.96 and 0.98 during hospitalization had a decreased mortality compared to those with SpO 2 < 0.96 [hypoxia group; odds ratio ( OR) = 2.659, 95% confidence interval (95% CI) was 2.190-3.229, P < 0.001] and SpO 2 > 0.98 (hyperoxia group; OR = 1.594, 95% CI was 1.337-1.900, P < 0.001). Kaplan-Meier survival curve showed that patients with SpO 2 between 0.96 and 0.98 during hospitalization had a higher probability of survival than those patient with SpO 2 < 0.96 and SpO 2 > 0.98 (Log-Rank test: χ2 = 113.400, P < 0.001). Sensitivity analyses demonstrated that, with the exception of subgroups with smaller sample sizes, across the strata of age, gender, body mass index (BMI), admission type, race, heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, respiratory rate, body temperature, myocardial infarction, congestive heart failure, cerebrovascular disease, chronic liver disease, diabetes mellitus, sequential organ failure assessment (SOFA), simplified acute physiology score Ⅱ (SAPSⅡ), systemic inflammatory response syndrome score (SIRS), and Glasgow coma score (GCS), the mortality of patients with SpO 2 between 0.96 and 0.98 was significantly lower than those of patients with SpO 2 < 0.96 and SpO 2 > 0.98. Conclusions:During hospitalization, the level of SpO 2 among sepsis patients exhibits a U-shaped relationship with in-hospital all-cause mortality, indicating that heightened and diminished oxygen levels are both associated with increased mortality risk. The optimal SpO 2 range is determined to be between 0.96 and 0.98.

Objective To analyze the current status of dyslipidemia among employees in a petrochemical enterprise and its influencing factors. Methods A total of 1 636 employees from a petrochemical enterprise were selected as the research subjects by the judgment sampling method. Peripheral venous blood was collected from the research subjects to detect total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C) and low- density lipoprotein cholesterol (LDL-C) in serum. The Effort-Reward Imbalance (ERI) Questionnaire was used to investigate occupational stress in the ERI model. Results The detection rate of dyslipidemia among the research subjects was 52.7%. The detection rates of abnormal total cholesterol, triglyceride, LDL-C, and HDL-C were 35.7%, 31.4%, 24.3%, and 10.0%, respectively. The detection rate of high occupational stress among the research subjects was 26.3%. The result of multivariate logistic regression analysis showed that the risks of dyslipidemia in overweight and obese employees were higher than that of normal body mass [ odds ratio (OR) and 95% confidence interval (CI) were 2.111 (1.692-2.634) and 2.346 (1.591-3.458), both P<0.01]. The risk of dyslipidemia in lean body mass employees was lower than those with normal body mass [OR (95%CI) was 0.130 (0.030-0.564), P<0.05]. The risk of dyslipidemia in smokers was higher than that in non-smokers [OR (95%CI) was 1.462 (1.124-1.902), P<0.01]. Employees with 20-30 years and ≥ 30 years of service had higher risks of dyslipidemia than those with <10 years of service [OR (95%CI) were 1.411 (1.038-1.919) and 1.869 (1.202-2.906), respectively, both P<0.05]. The risk of dyslipidemia among employees with high effort level of occupational stress in ERI model was higher than those with low effort level [OR (95%CI) was 1.351(1.045-1.745), P<0.05]. Conclusion Dyslipidemia prevalence is relatively high among the petrochemical enterprise employees. Overweight, obesity, smoking, long service years, and occupational stress in ERI model are influencing factors of dyslipidemia. To prevent dyslipidemia, it is necessary to strengthen blood lipid monitoring and lifestyle intervention in personnel with overweight, obesity, smoking, long service years, and occupational stress in ERI model.

Objective:To delineate the clinical characteristics and outcomes associated with severe cardiac toxicity during the preconditioning phase of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with aplastic anemia (AA).Methods:This retrospective case series study included 31 patients with severe AA who underwent allo-HSCT and were diagnosed with severe cardiac toxicity at the Hematology Department of Peking University People′s Hospital from August 2012 to June 2022. The clinical manifestations of severe cardiac toxicity observed during the preconditioning process were assessed. Patient survival was assessed using the Kaplan-Meier method.Results:In this cohort of 31 patients, the median follow-up period was 9 days (range: 4-365 days). Severe cardiac toxicity manifested within 6 days after the initial cyclophosphamide (Cy) administration. Twenty patients died within 30 days of initiating Cy preconditioning, of which 16 patients died due to severe cardiac toxicity within 25 days. Patients whose cardiac function improved within 30 days post-preconditioning showed a median survival duration of 222 days ( n=11). Troponin I (TNI) levels in patients who died within 30 days of initiating Cy preconditioning began increasing on day 5 post-Cy, peaking sharply by day 9 after a notable rise on day 8. B-type natriuretic peptide (BNP) levels in patients who died within 30 days of initiating Cy preconditioning started to rise from day 1, stabilized between days 2 and 5, and then doubled daily from days 6 to 8, remaining elevated thereafter. Notably, the initial increases in BNP and TNI correlated with electrocardiogram (ECG) signs of low voltage and T-wave inversion in 83.87% of cases ( n=26). Most patients ( n=28, 90.32%) were administered corticosteroid therapy. In those with restored cardiac function, the ejection fraction returned to >50% within 30 days of initiating Cy preconditioning. Conclusions:Patients with severe cardiac toxicity during the preconditioning phase of allo-HSCT typically exhibit early, sustained, and marked elevations in myocardial damage markers, including BNP and TNI, accompanied by ECG abnormalities following Cy administration, with BNP often increasing first. These indicators are associated with rapid disease progression and high mortality. Prompt initiation of treatment upon clinical diagnosis is critical for improving survival outcomes.

Objective:To explore the value of combined detection of urinary kidney injury markers in the diagnosis of early-stage diabetic kidney disease (DKD), and to provide evidence for early-stage DKD screening.Methods:It was a retrospective study. The clinical data of patients with type 2 diabetes mellitus (T2DM) from the Second Affiliated Hospital of Hainan Medicine University from January 2022 to August 2023 were collected. According to urinary microalbumin/creatinine ratio (UACR), the patients were divided into three groups: isolated diabetes group (UACR < 30 mg/g), early-stage DKD group (30 mg/g ≤ UACR < 300 mg/g) and clinical DKD group (UACR ≥ 300 mg/g), and the differences of clinical data among three groups were compared. Glomerular injury markers urinary microalbumin, transferrin, immunoglobulin (Ig) and α2 macroglobulin, and renal tubule injury markers α1 microglobulin (α1-MG), β2 microglobulin (β2-MG), retinol-binding protein (RBP), N-acetyl-β- D-glucosidase (NAG), neutrophil gelatinase-associated lipid carrier protein (NGAL) were measured. Spearman correlation method was used to analyze the correlation between urinary kidney injury markers and clinical indicators. Multivariate logistic regression analysis method was used to analyze the risk factors of DKD occurrence (UACR > 300 mg/g). Receiver-operating characteristic curve was used to analyze the value of individual and combined detection of urinary renal injury markers in the diagnosis of early-stage DKD (30 mg/g ≤ UACR < 300 mg/g). Results:A total of 116 T2DM patients were enrolled in this study, aged (61.99±12.56) years old (30 to 91 years old), with 79 males (68.1%). There were 44 (37.9%) isolated diabetes patients, 27 (23.3%) early-stage DKD patients, and 45 (38.8%) clinical DKD patients. Serum creatinine (Scr, H=34.183, P<0.001) and blood urea nitrogen (BUN, H=34.082, P<0.001) in clinical DKD group were higher than those in isolated diabetes group and early-stage DKD group. Spearman correlation analysis showed that glomerular injury markers urinary microalbumin, transferrin, Ig and α2 macroglobulin were positively correlated with Scr, BUN and UACR, and negatively correlated with estimated glomerular filtration rate and serum albumin (all P<0.05). Renal tubule injury markers urinary α1-MG, β2-MG, NAG, RBP, and NGAL were positively correlated with Scr, BUN and UACR, and negatively correlated with estimated glomerular filtration rate and serum albumin (all P<0.05). Multivariate logistic regression analysis indicated that systolic blood pressure ≥ 140 mmHg ( OR=1.033, 95% CI 1.008-1.060, P=0.010), high urinary microalbumin ( OR=1.018, 95% CI 1.007-1.030, P=0.001), high urinary RBP ( OR=1.309, 95% CI 1.086-1.577, P=0.005), high urinary NGAL ( OR=1.004, 95% CI 1.000-1.008, P=0.037), low serum albumin ( OR=0.833, 95% CI 0.749-0.926, P=0.001) and low urinary Ig ( OR=0.994, 95% CI 0.990-0.999, P=0.018) were independent influencing factors of DKD occurrence. Receiver-operating characteristic curve revealed that the area under the curve ( AUC) was the largest for diagnosing early-stage DKD when urinary microalbumin was detected alone ( AUC=0.976, 95% CI 0.955-0.997, P<0.001), with sensitivity and specificity of 95.6% and 90.1%, respectively. The combined detection of urinary microalbumin + Ig + transferrin + α2 macroglobulin + α1-MG + β2-MG + NAG + RBP + NGAL had an AUC of 0.986 (95% CI 0.971-1.000, P<0.001), with sensitivity and specificity of 93.3% and 98.5%, respectively, which was better than each single index. Further optimized detection combination was urinary microalbumin combined with β2-MG and NGAL, which had the best diagnostic efficacy ( AUC=0.978, 95% CI 0.958-0.999, P<0.001), with sensitivity and specificity of 95.6% and 93.0%, respectively. Conclusions:Compared with the single detection of each index, the combined detection of urinary glomerular injury and renal tubule injury markers has higher value in diagnosing early-stage DKD. The combined detection of urinary microalbumin combined with β2-MG and NGAL has the highest value in diagnosing early-stage DKD.

Objective To analyze the application effect of whole-course multi-disciplinary nutrition model in elderly patients undergoing hip surgery.Methods A total of 90 elderly patients undergoing hip surgery admitted to Wenzhou Central Hospital from October 2021 to December 2023 were selected and divided into control group and study group according to random number table method,with 45 cases in each group.The control group was treated with dietary management model,while the study group was treated with whole-course multi-disciplinary nutrition model.Recovery,nutritional status,quality of life,hip function and satisfaction were compared between two groups.Results The hospital stay and fracture healing time in study group were significantly shorter than those in control group(P<0.05).After intervention,prealbumin(PA),albumin(Alb),hemoglobin(Hb),dimensions scores of 36-item short form health survey(SF-36)and Harris hip scores of patients in two groups were significantly higher than before intervention(P<0.05).PA,Alb,Hb,dimensions scores of SF-36 and Harris hip scores in study group were significantly higher than those in control group(P<0.05).The satisfaction of patients in study group was significantly higher than that in control group(χ2=5.075,P=0.024).Conclusion The application of whole-course multi-disciplinary nutrition model in hip surgery in elderly patients can improve their nutritional status,improve their quality of life,enhance hip function,and facilitate postoperative recovery.
