ObjectiveTo investigate the effects and mechanisms of Fangji Fulingtang （FFD） on mitochondrial function in the mouse model of myocardial fibrosis （MF）. MethodsSixty SPF-grade male C57BL/6J mice were randomly allocated into six groups （n=10 per group）： control， model， low-dose， medium-dose， and high-dose （3.315， 6.63， and 13.26 g·kg^-1， respectively） FFD， and captopril （20 mg·kg^-1）. MF was induced by subcutaneous injection of isoproterenol （10 mg·kg^-1·d^-1） in other groups except the control group for 14 consecutive days， with simultaneous gavage of corresponding drugs. Left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） were measured by echocardiography. Serum levels of creatine kinase-MB （CK-MB）， cardiac troponin I （cTnI）， N-terminal pro-brain natriuretic peptide （NT-pro BNP）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） were determined by enzyme-linked immunosorbent assay （ELISA）. Malondialdehyde （MDA）， superoxide dismutase （SOD）， and glutathione （GSH） levels were measured by biochemical assays. Reactive oxygen species （ROS） were detected by dihydroethidium （DHE） fluorescence staining. Hematoxylin-eosin （HE）， Masson's trichrome， and wheat germ agglutinin （WGA） staining were performed to evaluate myocardial structure and fibrosis. Mitochondrial ultrastructure and function were assessed by transmission electron microscopy， adenosine triphosphate （ATP） colorimetric assay， and JC-1 fluorescence staining. The protein levels of phosphorylated adenosine monophosphate-activated protein kinase α subunit （p-AMPKα）， AMPKα， peroxisome proliferator-activated receptor gamma coactivator-1α （PGC-1α）， mitofusin 2 （MFN2）， pyruvate kinase M2 isoform （PKM2）， lactate dehydrogenase A （LDHA）， and hypoxia-inducible factor 1 alpha （HIF-1α） were analyzed by Western blot. ResultsCompared with the control group， the model group exhibited decreased LVEF and LVFS， increased heart weight index and heart weight-to-tibia length ratio （P<0.01）， elevated levels of myocardial injury markers （CK-MB， cTnI， and NT-pro BNP）， inflammatory cytokines （TNF-α， IL-1β， and IL-6）， and MDA， along with reduced SOD and GSH levels （P<0.01）. Enhanced interstitial collagen deposition and cardiomyocyte hypertrophy were observed in the model group （P<0.01）. Transmission electron microscopy and JC-1 staining revealed mitochondrial swelling， crista disruption， decreased ATP content， and reduced red/green fluorescence ratio in the model group （P<0.01）. Western blot analysis demonstrated downregulation of p-AMPKα， PGC-1α， and MFN2 and upregulation of PKM2， LDHA， and HIF-1α in the model group （P<0.01）. Compared with the model group， treatment with FFD or captopril improved LVEF and LVFS， reduced heart weight index and heart weight-to-tibia length ratio （P<0.05， P<0.01）， lowered the serum levels of CK-MB， cTnI， NT-pro BNP， TNF-α， IL-1β， IL-6， and MDA， increased the SOD and GSH levels （P<0.05， P<0.01）， attenuated the myocardial fibrosis and cardiomyocyte hypertrophy （P<0.01）， and restored the mitochondrial ultrastructure. The medium and high-dose FFD groups as well as the captopril group showed increased ATP production and red/green fluorescence ratio （P<0.05， P<0.01）. Furthermore， FFD upregulated the expression of p-AMPKα and PGC-1α while downregulating the expression of LDHA and HIF-1α （P<0.05， P<0.01）. ConclusionFFD activates the AMPK/PGC-1α/MFN2 signaling pathway and inhibits the PKM2/LDHA/HIF-1α axis to restore mitochondrial function and energy metabolic homeostasis， thereby attenuating isoproterenol-induced myocardial fibrosis.

OBJECTIVE To evaluate the quality of Zhachong-13 pills.METHODS The contents of agarotetrol， costunolide， hypaconitine， dehydrocostus lactone， mesaconitine， aconitine， liquiritigenin， glycyrrhizic acid， ellagic acid， liquiritin， corilagin， and gallic acid in 18 batches of samples were determined by high-performance liquid chromatography-tandem triple quadrupole mass spectrometry （HPLC-MS/MS） method. Cluster analysis （CA） was performed using the Microbioinformatics online analysis platform. Principal component analysis （PCA） and orthogonal partial least squares discriminant analysis （OPLS-DA） were performed using SIMCA 14.1 software. Random forest， extremely randomized trees， and extreme gradient boosting machine learning models were constructed using the SPSSAU online analysis platform. The comprehensive quality of the samples was evaluated by the entropy weight-technique for order preference by similarity to ideal solution （TOPSIS） method.RESULTS The contents of the above 12 components were 104.331-694.382， 652.217-1 085.075， 6.051-130.980， 612.174-1 417.179， 1.018-32.239， 0.953-24.967， 65.552-652.239， 2 019.412-5 385.807， 52.867-4 990.450， 156.307-883.180， 10.142-475.722， and 1 102.863-4 826.396 μg/g， respectively. The results of CA and PCA showed that the 18 batches of samples were divided into two categories： S1-S6， S10-S15 were grouped into one category， while S7-S9 and S16-S18 were grouped into another category. The OPLS-DA results showed that the variable importance in projection values of mesaconitine， glycyrrhizic acid， liquiritin， ellagic acid， hypaconitine， liquiritigenin， agarotetrol， gallic acid， and dehydrocostus lactone were greater than 1. The results of the three machine learning models showed that ellagic acid and hypaconitine had relatively large differential contributions. The entropy weight-TOPSIS results showed that the overall quality of samples from manufacturer B was superior to that of the other four manufacturers.CONCLUSIONS The established method is stable and feasible， and can be used to evaluate the quality of Zhachong-13 pills， in combination with multivariate statistical analysis. Ellagic acid and hypaconitine are differential markers that affect its quality.

Objective:To explore the correlation between serum nidogen-2 (NID-2) and thoracic aortic calcification in patients with chronic kidney disease (CKD), and construct a risk prediction model based on NID-2 to evaluate its value in predicting the risk of the severe thoracic aortic calcification and cardiovascular and cerebrovascular events in CKD patients.Methods:It was a prospective cohort study. Patients with CKD at stage 3 to 5D in the Zhongda Hospital Affiliated to Southeast University from January 2022 to January 2023 were enrolled. Syngo.via software was used to evaluate the volume of thoracic aortic calcification, and enzyme-linked immunosorbent assay was employed to determine the level of serum NID-2. According to the volume of thoracic aortic calcification, the patients were divided into three groups: no calcification group, mild calcification group and severe calcification group. The top 25% of the patients were defined as no or mild calcification group, and the latter 75% were defined as severe calcification group. The follow-up period was one year. During the follow-up period, cardiovascular and cerebrovascular events, as well as all-cause death among the enrolled patients were recorded. Logistic regression analysis was used to screen the influencing factors of thoracic aortic calcification. Based on the results of logistic regression analysis, a nomogram prediction model was constructed. The receiver operating characteristic curve (ROC curve), calibration curve, and decision curve were employed to evaluate the discrimination, calibration and clinical practicality of the nomogram model.Results:A total of 132 patients were included, with 91 males (68.94%) and age of (56.51±16.37) years. There were 60 CKD 3-5 stage patients (non-dialysis, 45.45%) and 72 CKD 5D patients (dialysis, 54.55%). Serum ND-2 levels differed significantly among healthy individuals, dialysis patients and non-dialysis patients ( H=70.651, P<0.001). There was no statistically significant difference in serum NID-2 level between the no or mild calcification group and the severe calcification group in dialysis patients ( Z=350.00, P=0.426). The serum NID-2 level in the severe calcification group was significantly higher than that in the no or mild calcification group in non-dialysis patients ( Z=242.00, P=0.019). In non-dialysis patients, there was a statistically significant correlation between serum NID-2 level and volume of thoracic aortic calcification ( r=0.40, P<0.001). In dialysis patients, there was no statistically significant correlation between serum NID-2 level and volume of each segment of thoracic aortic calcification (all P>0.05). The univariate logistic regression analysis showed that, age, hemoglobin, serum albumin, estimated glomerular filtration rate, NID-2, hypertension, type 2 diabetes mellitus and cerebral infarction were correlated factors of thoracic aortic calcification in non-dialysis patients (all P<0.05). Multivariate logistic regression analysis showed that age ( OR=1.22, 95% CI 1.08-1.50, P=0.010) was an independent correlated factor of thoracic aortic calcification in non-dialysis patients. The above related variables of univariate logistic regression analysis were incorporated into a nomogram to construct a predictive model for severe vascular calcification in non-dialysis patients, yielding an AUC of 0.94 (95% CI 0.89-0.99) in ROC curve, with a sensitivity of 83% and a specificity of 95%. A nomogram model based on above variables for predicting cardiovascular and cerebrovascular events in non-dialysis patients demonstrated an AUC of 0.95 (95% CI 0.90-1.00) in ROC curve, with a sensitivity of 95% and a specificity of 87%. Conclusions:In non-dialysis patients, serum NID-2 level in the severe calcification group is significantly higher than that in the no or mild calcification group. The serum NID-2 is a related factor of thoracic aortic calcification and cardiovascular and cerebrovascular events in non-dialysis patients. The nomogram prediction model constructed by combining NID-2 with age, hemoglobin, serum albumin, estimated glomerular filtration rate, hypertension, type 2 diabetes mellitus and cerebral infarction has a high predictive value for the risk of thoracic aortic calcification as well as cardiovascular and cerebrovascular events in non-dialysis patients.

Objective:To analyze the epidemiological characteristics and delay in detection of reported brucellosis cases in Nangang District of Harbin City, Heilongjiang Province, in order to provide a basis for improving targeted measures for brucellosis prevention and control.Methods:Data on brucellosis reported in Nangang District of Harbin City between 2018 and 2022 were obtained from the China Disease Prevention and Control Information System. A descriptive analysis was conducted to outline the epidemiological status, epidemiological features, and sources of cases. Seasonal patterns of brucellosis were assessed using the concentration degree and seasonal index methods. Joinpoint regression model was used to analyze the trend of delay in detection.Results:From 2018 to 2022, a total of 4 428 cases of brucellosis were reported in Nangang District, with 1 183 cases (26.72%) reported in 2018 and 528 cases (11.92%) reported in 2022. The gender ratio of the cases was 2.80 ∶ 1.00 (3 264 ∶ 1 164). Most cases occurred in individuals aged 30 to 59 years (73.19%, 3 241/4 428). Occupationally, farmers comprised the majority of cases (88.73%, 3 929/4 428), followed by homemakers/unemployed individuals (3.73%, 165/4 428), and students (2.03%, 90/4 428). Regarding case origin, 31.48% (1 394/4 428) were from Harbin City, while 64.97% (2 877/4 428) originated from other cities within Heilongjiang Province, predominantly from Suihua City (38.89%, 1 722/4 428). Additionally, 157 cases (3.55%, 157/4 428) were reported from outside Heilongjiang Province, all of which were from Inner Mongolia Autonomous Region and Jilin Province. Brucellosis incidence showed weak seasonality ( M = 0.230), with the epidemic period spanning from March to August. During this period, seasonal indices C exceeded 100%, peaking in July (168.02%). From 2018 to 2022, the average annual delay rate in case detection was 20.14% (892/4 428). The delayed detection rates of brucellosis cases in each year were 30.68% (363/1 183), 17.86% (200/1 120), 17.23% (117/679), 12.75% (117/918), and 17.99% (95/528), respectively (average annual percentage change = - 17.52%, P = 0.090). Conclusions:Brucellosis in Nangang District of Harbin Citydemonstrates weak seasonality, with peak incidence occurring from March to August. Detection delays remain a concern, highlighting the need for sustained surveillance and the implementation of integrated, multi-sectoral prevention and control measures.

Objective To explore the efficacy of Chu's Antai formula combined with dydrogesterone for the treatment of unexplained recurrent abortion(URA)with kidney deficiency pattern and its possible mechanism of action.Methods A total of 68 patients with URA with kidney deficiency pattern admitted to our hospital between April 2023 and October 2023 were selected and randomly divided into the study and conventional groups,with 34 patients in each group.The conventional group received luteal support therapy with oral dydro-gesterone(10 mg twice daily),whereas the study group received an additional Chu's Antai formula(one dose/d,divided into morning and evening doses)based on conventional treatment.Both groups were treated until 14 weeks of gestation.The t test,x2 test,and Fisher's exact test were performed to compare the traditional Chinese medicine(TCM)symptom scores,serum sex hormone levels(estradiol[E2],progesterone[P],and human chorionic gonadotropin[HCG]),inflammatory cytokine levels,clinical efficacy,adverse reactions,and preg-nancy outcomes between the two groups before and after treatment.Results After treatment,the primary symptom,secondary symptom,and total scores were lower in the study group than in the conventional group(P＜0.05).The total effective treatment rate was higher in the study group than in the conventional group(P＜0.05).After treatment,serum E2,P,and HCG levels in both groups were higher than those before treatment(P＜0.05),and the study group showed higher sex hormone levels than the conventional group(P＜0.05).After treatment,interleukin(IL)-2,tumor necrosis factor α(TN F-α),interferon γ(INF-γ),and IL-17 serum levels in both groups were lower than those before treatment(P＜0.05);IL-2,TNF-α,INF-γ,and IL-17 levels were significantly lower in the study group than in the con-ventional group(P＜0.05).After treatment,IL-4,IL-6,IL-10,and transforming growth factor β1(TGF-β1)serum levels in both groups were higher than those before treatment(P＜0.05),and IL-4,IL-6,IL-10,and TGF-β1 levels in the study group were significantly higher than those in the conventional group(P＜0.05).No significant adverse reactions were observed in any group.Notably,the pregnancy suc-cess rate was higher in the study group than in the conventional group(73.53％vs.47.06％,P＜0.05).Conclusion Chu's Antai formula combined with dydrogesterone improved TCM symptoms,hormone levels,and pregnancy outcomes in patients with URA with kidney defi-ciency pattern,thereby enhancing clinical efficacy.The underlying mechanism may involve the restoration of the balance between Th1/Th2 and Th17/Treg cells.
