Chronic heart failure （CHF） is a clinical syndrome characterized by impaired ventricular ejection function due to cardiac abnormalities， representing the terminal stage of most cardiovascular diseases. With its rising prevalence and significant impact on patients' quality of life， CHF has emerged as a major global public health concern. Current Western medicine treatments mainly involve the oral administration of the "new quadruple therapy" drugs and diuretics. Despite substantial progress in pathological research and clinical treatment， challenges persist， including considerable side effects， drug resistance， and marked interindividual variability in therapeutic response. Therefore， exploring and leveraging the advantages of traditional Chinese medicine （TCM） in treating CHF has become an urgent research priority. TCM has a millennia-long history in the prevention and treatment of heart failure， accumulating extensive clinical experience. Characterized by its multi-component and multi-target properties， TCM enables holistic regulation of multiple systemic functions and intervention in the progression of heart failure， demonstrating significant clinical relevance in its management. By employing therapeutic strategies such as warming Yang， promoting diuresis， replenishing Qi， nourishing Yin， and activating blood circulation， TCM effectively improves myocardial fibrosis， inhibits oxidative stress responses， enhances myocardial contractility， and ameliorates ventricular remodeling. Modern proprietary Chinese medicines derived from classic formulas， based on the theoretical foundation of traditional prescriptions， not only exhibit favorable clinical efficacy but also offer notable advantages in convenience， stability， and safety. This review systematically examined the significant therapeutic effects and underlying mechanisms of classical TCM formulas in the treatment of CHF， and provided an overview of the clinical application of modern proprietary Chinese medicines. It aims to provide new strategies for the clinical diagnosis and treatment of CHF.

Objective To explore the mechanism by which breast cancer-derived LncRNA OIP5-AS1 regulates the migration, invasion, and epithelial-mesenchymal transition of breast cancer cells through the M2 polarization of tumor-associated macrophages (TAM). Methods MDA-MB-231 cells were divided into the control group (blank control), the NC group (transfected with NC siRNA), and the si-OIP5 group (transfected with LncRNA OIP5-AS1 siRNA). The mRNA expression levels of LncRNAs OIP5-AS1, IL-4, and IL-13 were detected by RT-qPCR. The protein expression levels of IL-4 and IL-13 in the culture supernatant were detected by ELISA. The culture supernatant from the control group was added to RPMI 1640 medium at different volume ratios to induce the polarization of M0 macrophages into TAMs. The mRNA expression of CD206 in TAMs was detected by RT-qPCR. M0-type macrophages were induced with the medium supernatant of the NC group/si-OIP5 group, and the expression of CD206 was detected by Western blot. Subsequently, a co-culture model of macrophage and MDA-MB-231 was constructed to evaluate the migration and invasion abilities of MDA-MB-231 cells and detect the expression changes in Vimentin, N-cadherin and E-cadherin. Results Compared with the control and NC groups, the si-OIP5 group showed significantly downregulated expression of LncRNA OIP5-AS1 (P<0.001) and significantly decreased IL-13 mRNA and protein levels (P<0.05). Meanwhile, no significant difference was observed in the expression of IL-4 among the groups. Conditioned medium induced CD206 expression in M0 macrophages in a volume-dependent manner, with the strongest effect at a 40% volume ratio (P<0.001). The CD206 protein level in the si-OIP5 group significantly decreased (P<0.01). In the co-culture system, the migration and invasion abilities of MDA-MB-231 cells in the si-OIP5 group significantly weakened (P<0.001), the expression of E-cadherin was upregulated, and the expression levels of N-cadherin and Vimentin were downregulated (both P<0.01). Conclusion Breast cancer-derived LncRNA OIP5-AS1 can induce TAM M2 polarization mediated by IL-13, thereby promoting the migration, invasion, and EMT of breast cancer cells.

Objective::To evaluate the diagnostic efficacy and clinical application of the Obstetrical Chinese Disseminated Intravascular Coagulation (DIC) Scoring System (OCDSS).Methods::This study is a retrospective study that collected 1063 cases from Wuhan Union Hospital, Yichang Central People’s Hospital, and the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture between July 2017 and June 2024. These cases were divided into DIC and non-DIC groups based on score standard. Diagnosis of DIC, the rate of hysterectomy, neonatal mortality, and severe asphyxia are the main outcome measures. All the laboratory indicators are all determined by clinical laboratory department of the hospital. Data were expressed as mean ± standard deviation or median (interquartile range) and frequencies. Independent sample t-test or non-parametric test were used to compare measurement data, while the chi-square test was used for count data. Receiver operating characteristic (ROC) curve and area under curve (AUC) were used to test the predictive accuracy. Using univariate and multivariate logistic regression analysis to study the high-risk factors. P < 0.050 indicates a statistical significance. Results::Of 1063 participants in this study, 29 participants (2.73%) were diagnosed with obstetrical DIC by OCDSS score standard, and all the participants were diagnosed as DIC with underlying disease. When the Takao, Clark, and Erez score standard is the "gold standard", the OCDSS score standard always shows good sensitivity and specificity, with all the AUC over 0.75. OCDSS score standard also has better predictive of hysterectomy (68.18%, 91.07%, 0.872), severe neonatal asphyxia and death (79.17%, 75.07%, 0.842) than the other three score standards. All the indicators included in the OCDSS score standard contributed to the DIC diagnosis (all the P < 0.001). The indicators in the DIC group were more abnormal than the non-DIC group (all the P < 0.001). Conclusion::OCDSS is a first score standard, especially for pregnancies, it considers the underlying disease, clinical symptoms, and laboratory results. This score system shared a good diagnosis performance for DIC in the Chinese population and may help clinicians make timely decisions.

Objective:To analyze the biological parameters of the anterior segment of age-related cataracts patients with or without zonular weakness with the new generation of sweep-source anterior optical coherence tomography (OCT) device CASIA2 to provide a basis for the diagnosis of zonular weakness.Methods:A case-control study was conducted.A total of 158 cases (186 eyes) of patients with age-related cataracts having zonular weakness as a zonular weakness group, and 80 cases (80 eyes) of cataract with age-related cataracts without zonular weakness as a normal zonule group were enroll from June 2022 to June 2023 at Beijing Tongren Hospital.All patients underwent routine preoperative ophthalmological examination including slit lamp microsopy, IOLMaster 700, ocular B-ultrasound and OCT.The anterior chamber depth (ACD), anterior chamber volume (ACV), lens thickness (LT), lens vault (LV), anterior chamber angle opening distance at 750 μm (AOD750), lens decentration and tilt, radius of curvature of the anterior lens surface (RAL), and radius of curvature of the posterior lens surface (RPL) of patients were measured with CASIA2 and compared between the two groups.The relationship between zonular weakness and anterior chamber parameters and lens parameters was evaluated by logistic regression analysis.This study followed the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital (No.TRECKY2018-049), and all enrolled patients signed the informed consent form.Results:In the zonular weakness group, ACD, ACV, RAL, and AOD750 were (2.34±0.56)mm, (85.05±40.19)mm 3, 7.52 (7.13, 8.08)mm, and 0.27 (0.07, 0.30)mm, respectively, which were smaller than (3.13±0.38)mm, (127.75±38.15)mm 3, 9.28(8.51, 9.76)mm, and 0.52 (0.31, 0.65)mm in the normal zonule group, with statistically significant differences (all P<0.05).LT and LV in the zonular weakness group were (5.14±0.45)mm and (1.22±0.53)mm, respectively, which were larger than (4.27±0.52)mm and (0.32±0.30)mm in the normal zonule group, and the differences were statistically significant (both P<0.05).Magnitude of lens decentration and tilt in the zonular weakness were 0.34 (0.13, 0.45)mm and 6.44 (3.67, 7.32)°, respectively, which were significantly larger than 0.19 (0.12, 0.25)mm and 4.88 (3.85, 5.65)° in the normal zonule group (both P<0.05).No obvious pattern was found in the direction of decentration and tilt.Logistic regression analysis showed that LV and lens decentration were risk factors of zonular weakness (odds ratios [ OR]=706.170, 335.339; both P<0.05), and RAL was a protective factor of zonular weakness ( OR=0.239, P<0.05). Conclusions:Age-related cataract patients with zonular weakness often present with a decrease in ACV due to increased anterior convexity of the lens.Decreased RAL, increased lens decentration and elevated LV are risk factors for zonular weakness.

Objective::To investigate the correlation between maternal serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and gestational duration in pregnant women with pulmonary hypertension (PH).Methods::The study included pregnant individuals with PH stemming from mitral valve stenosis and mitral valve regurgitation (post-capillary PH) or pulmonary arterial hypertension (pre-capillary PH) who were admitted to Guangdong Provincial People’s Hospital between January 1, 2014 and December 31, 2020. In this retrospective cohort study, maternal serum NT-proBNP levels during pregnancy, along with other clinical data, were obtained from structured electronic medical records. These data included gestational age at delivery, echocardiographic parameters, laboratory findings, gestational duration, delivery mode, and other relevant clinical variables. Univariate and multivariate regression analyses were conducted to assess the association between NT-proBNP levels and gestational duration. Adjustments were made for potential confounding factors, and curve fitting and threshold effect analysis were employed to identify tangent points. Furthermore, stratified analyses were performed based on tricuspid regurgitation velocity, maternal age, and parity.Results::A total of 64 patients with post-capillary PH and 74 patients with pre-capillary PH were included in this study. Among patients with post-capillary PH, the results of multivariate regression analysis indicated a significant association between maternal NT-proBNP levels and gestational duration (β = -0.03, 95% confidence interval (CI) -0.05 to 0.00, P = 0.02). The fitted curve demonstrated a negative correlation between maternal NT-proBNP levels and gestational duration, with a significant break point at 379.9 ng/L ( P < 0.05). In the post-capillary PH group, the stratified analysis revealed a regression coefficient of -0.05 (95% CI:-0.06 to -0.04, P = 0.001) in patients with a tricuspid regurgitation velocity >340 mm/s. For patients >35 years old, the regression coefficient was -0.03 (95% CI -0.06 to -0.01, P = 0.02). In multiparous women, the regression coefficient was -0.03 (95% CI-0.06 to 0.00, P = 0.03). Conclusion::In pregnant women with pulmonary hypertension, maternal NT-proBNP levels are associated with gestational duration, particularly with an increased risk of preterm labor.

Objective:To investigate the effect of robot-assisted total knee arthroplasty (TKA) on the incidence of postoperative deep vein thrombosis (DVT) in the lower limbs.Methods:A total of 405 patients who underwent primary unilateral TKA in the Department of Orthopaedics, Peking University Third Hospital from June 2022 to June 2024 were retrospectively analyzed, consisting of 89 males and 316 females, with a mean age of 67.84±5.60 years. Patients were divided into the conventional group ( n=215) and the robot-assisted group ( n=190) according to the surgical approach. Postoperative DVT incidence, operative time, postoperative hemoglobin and hematocrit levels, perioperative blood loss, and transfusion rate were compared between the two groups to evaluate the impact of robot-assisted TKA on thrombotic events and related clinical indicators. Results:There were no significant differences in age, sex, height, weight, body mass index, or preoperative laboratory results including hemoglobin and hematocrit levels between the two groups ( P>0.05). The postoperative DVT incidence was 26.8% (51/190) in the robot-assisted group and 34.9% (75/215) in the conventional group, with no significant difference ( P>0.05). Univariate logistic regression analysis showed that sex ( P=0.013) and age ( P=0.024) were significantly associated with DVT occurrence. Multivariate logistic regression further revealed that female patients had a significantly higher incidence of DVT than males ( OR=0.438, P=0.005), and older patients had a significantly increased risk of DVT ( OR=1.046, P=0.025); body mass index remained not significantly associated with DVT ( P=0.092). The operative time in the robot-assisted group was 88.62±18.58 min, which was significantly longer than that in the conventional group 79.23±17.68 min ( t=-5.207, P<0.001). Perioperative total blood loss was 1 079.85±344.18 ml in the robot-assisted group and 1 141.47±363.70 ml in the conventional group, with no significant difference ( t=1.745, P=0.082). The transfusion rate was 5.3% in the robot-assisted group and 5.1% in the conventional group, respectively, with no significant differences (χ 2=0.004, P=0.947). Conclusion:Compared with conventional TKA, robot-assisted TKA results in longer operative time but does not increase perioperative blood loss or the risk of postoperative DVT.
