ObjectiveTo investigate the effect and mechanism of Shengxian Yixin Granule （升陷益心颗粒， SYG） in treating heart failure with preserved ejection fraction （HFpEF）. MethodsExperiment 1： Forty male C57BL/6 mice were randomly divided into control group， model group， low-dose ［25 mg/（kg·d）］， medium-dose ［50 mg/（kg·d）］， and high-dose ［（75 mg/（kg·d）］ SYG groups， with 8 mice per group. Except for the control group， HFpEF was induced by a high-fat diet combined with Nω-nitro-L-arginine methyl ester in drinking water for 16 weeks. After 10 weeks of modeling， treatment groups received corresponding doses of SYG by gavage， while the control group and model group received equal volume of normal saline， for 6 weeks. After 6 weeks of administration， the body weight， blood pressure including systolic blood pressure （SBP） and diastolic blood pressure （DBP）， and heart weight-to-tibia length ratio （HW/TL） were recorded. Echocardiography was used to evaluate left ventricular ejection fraction （LVEF） and the ratio of early to late diastolic transmitral flow velocity （E/A）. Plasma N-terminal pro-brain natriuretic peptide （NT-proBNP） and C-reactive protein （CRP） levels were measured by ELISA. The expression level of brain natriuretic peptide （BNP） in heart tissue was detected by qRT-PCR. Blood lipid levels， including low-density lipoprotein cholesterol （LDL-C）， triglycerides （TG）， and total cholesterol （TC）， were determined by a biochemical analyzer. Splenic proportions of M1 macrophages， M2 macrophages， T helper 17 （Th17） cells， and regulatory T （Treg） cells were analyzed by flow cytometry. Experiment 2： RAW 264.7 cells were stimulated with lipopolysaccharide （LPS） to establish an M1 macrophage polarization model， and then treated with SYG-containing serum for 24 h. The cells were divided into four groups， including blank serum group， high-dose SYG-containing serum group， LPS group， and LPS plus high-dose SYG-containing serum group. Combined with asignal transducer and activator of transcription 3 （Stat3） inhibitor for 24 h， the cells were divided into a lipopolysaccharide group， a high-dose SYG-containing serum group， an inhibitor group， and high-dose SYG-containing serum plus inhibitor group. The expression levels of inducible nitric oxide synthase （iNOS） and interleukin-1β （IL-1β） in each group were detected by qRT-PCR. The protein levels of iNOS， IL-1β， Stat3， and phosphorylated Stat3 （p-Stat3） were detected by Western Blotting. ResultsExperiment 1： Compared to the control group， the model group showed significantly decreased E/A ratio， and increased cardiac BNP expression， plasma NT-proBNP，HW/TL ratio， body weight， TC， LDL-C， SBP， and DBP， as well as shortened exhaustion distance and exhaustion time （P＜0.05 or P＜0.01）. Compared to the model group， the E/A ratio increased in the low-， medium-， and high-dose SYG groups； cardiac BNP expression decreased in the low- and high-dose groups， and plasma NT-proBNP levels decreased in the high-dose group； the HW/TL ratio and body weight decreased， while exhaustion distance and exhaustion time increased in the medium- and high-dose groups； TG levels decreased in the low- and medium-dose groups， and LDL-C levels decreased in the medium- and high-dose groups； SBP and DBP decreased in the low-， medium-， and high-dose groups （P＜0.05 or P＜0.01）. Compared to the low-dose SYG group， body weight decreased， and both exhaustion distance and exhaustion time increased in the medium- and high-dose groups （P＜0.05 or P＜0.01）. Compared to the medium-dose SYG group， the exhaustion time increased in the high-dose SYG group （P＜0.01）. Experiment 2： In the LPS‑induced M1 macrophage polarization model， compared to the blank serum group， the LPS group showed significantly increased mRNA and protein expression of iNOS and IL‑1β， as well as the p‑Stat3/Stat3 ratio （P＜0.01）. Compared to the LPS group， the high‑dose SYG-containing serum plus LPS group showed significantly decreased mRNA and protein expression of iNOS and IL‑1β， as well as the p‑Stat3/Stat3 ratio （P＜0.05 or P＜0.01）. Compared to the LPS group， the inhibitor group also showed significantly reduced these parameters （P＜0.05 or P＜0.01）. ConclusionSYG can improve cardiac function， ventricular remodeling， exercise capacity， and lipid metabolism in HFpEF mice， while inhibiting inflammatory responses. Its mechanism may be related to the regulation of the Stat3 signaling pathway and inhibition of M1 macrophage polarization.

ObjectiveThis paper aims to investigate the distribution patterns of traditional Chinese medicine syndromes in patients with chronic hepatitis B （CHB） comorbid with metabolically associated fatty liver disease （MAFLD） and analyze their correlation with clinical characteristics and the progression of liver fibrosis. MethodsA cross-sectional study method was employed， and 506 patients with CHB comorbid with MAFLD who attended the Hepatology Outpatient Department of Public Health Clinical Center of Chengdu from June 2024 to December 2024 were enrolled. General information， traditional Chinese medicine syndromes information， laboratory indicators， and imaging examination results were collected using case report forms （CRF）. Tongue images of patients were acquired using a tongue diagnosis instrument， and tongue feature parameters were extracted using computer image processing technology. Frequency analysis， factor analysis， and cluster analysis， and other methods were used to explore syndrome categories and distribution patterns. Non-parametric tests were used to compare the differences in clinical characteristics among different syndromes. Univariate and multivariate logistic regression analyses were performed to investigate the correlation between traditional Chinese medicine syndromes and the progression of liver fibrosis. ResultsThe main traditional Chinese medicine syndromes in patients with CHB comorbid with MAFLD were mainly dominated by damp-heat accumulation syndrome， liver stagnation and spleen deficiency syndrome， and phlegm-blood stasis syndrome， with damp-heat accumulation syndrome accounting for the highest proportion （41.89%）. Compared with those without damp-heat accumulation syndrome， patients with damp-heat accumulation syndrome had significantly lower tongue proper H value， tongue coating H value， and tongue coating a^* value （P<0.05）， significantly higher tongue coating b^* value （P<0.05）， significantly increased levels of white blood cell （WBC）， red blood cell （RBC）， hemoglobin （HGB）， and glucose （GLU）， increased CAP values （P<0.05）， a higher proportion of males （P<0.05）， and a younger age （P<0.05）. Univariate and multivariate logistic regression analyses show that age， hepatitis B surface antigen （HBsAg）， diabetes， and damp-heat accumulation syndrome are independent risk factors for liver fibrosis （P<0.05）， and that damp-heat accumulation syndrome is predominantly distributed in liver fibrosis stage F0-F1. ConclusionDamp-heat accumulation syndrome is a typical syndrome in patients with CHB comorbid with MAFLD， which is significantly associated with enhanced inflammatory response， metabolic disorders， and early liver fibrosis， and is a key link in disease progression. Clinical attention and early intervention are needed.

ObjectiveTo evaluate the therapeutic effect of Shenji Guben prescription （SJGB） on chronic obstructive pulmonary disease （COPD） in mice and to explore its potential therapeutic mechanism via transcriptomics. MethodsA mouse model of COPD was established by combined exposure to lipopolysaccharide （LPS） and cigarette smoke. C57BL/6J mice were randomly allocated into a control group， a model group， an acetylcysteine （78 mg·kg^-1·d^-1） group， and low- （7.5 g·kg^-1·d^-1）， medium- （15 g·kg^-1·d^-1）， and high-dose （30 g·kg^-1·d^-1） SJGB groups. After 13 weeks of modeling， oral administration was initiated and continued for 28 days. The therapeutic effects of SJGB were assessed based on body weight， lung function， lung tissue pathology， and inflammatory factors in bronchoalveolar lavage fluid （BALF）. Ultra-high performance liquid chromatography-tandem mass spectrometry （UHPLC-MS/MS） was employed to identify the active ingredients in SJGB. Transcriptomic profiling of lung tissue was performed by RNA-seq to identify differentially expressed genes （DEGs）， followed by gene ontology （GO） enrichment analysis， Kyotoencyclopedia of Genes and Genomes （KEGG） enrichment analysis， Gene Set Enrichment Analysis （GSEA）， and protein-protein interaction （PPI） network construction. Key genes were further validated by Western blot and Real‑time polymerase chain reaction （Real-time PCR）. ResultsAfter drug intervention， the final body weights of mice in medium- and high-dose SJGB groups were higher than those in the model group （P<0.05）. Compared with the model group， SJGB groups demonstrated a significant decrease in expiratory time （Te）， along with increases in peak expiratory flow （PEF）， 50% expiratory flow （EF50）， tidal volume （TV）， and expiratory volume （EV） （P<0.05）. High-dose SJGB ameliorated pathological changes in the lung tissue， reduced peribronchial inflammation scores， and decreased mean linear intercept （MLI） （P<0.01）. Compared with the model group， medium- and high-dose SJGB groups showed reductions in interleukin-6 （IL-6） and interleukin-1β （IL-1β） levels （P<0.01）. UHPLC-MS/MS revealed that the five most abundant components in SJGB were （S）-actinidine， ephedrine， pyroglutamic acid， methylephedrine， and coumarin. Transcriptomic analysis revealed 219 DEGs regulated by SJGB， suggesting that the anti-COPD effects of SJGB may be mediated through key genes such as cluster of differentiation 68 （CD68）， integrin subunit alpha X （ITGAX）， and cathepsin S （CTSS）， primarily involved in the lysosomal pathway. Western blot and Real-time PCR results confirmed that SJGB inhibited the expression of CD68， ITGAX， and CTSS compared with the model group （P<0.05）. ConclusionSJGB effectively improved the lung function and attenuated lung tissue inflammation in the mouse model of COPD by modulating the lysosomal pathway and related genes including CD68， ITGAX， and CTSS.

Objective The aim of the study is to analyze the incidence patterns and epidemiological characteristics of parasitic and vector-borne diseases in the Minhang and Jinshan districts of Shanghai, and provide evidence-based information for optimizing prevention and control measures. Methods We collected information from epidemic reports and epidemiological investigation forms for cases of parasitic and vector-borne diseases from 2005 to 2024 in Shanghai's Minhang and Jinshan districts. Descriptive epidemiological method were adopted to conduct a comparative analysis of incidence trends, epidemic characteristics, and infection sources. Results A total of 229 cases in 7 categories were reported between 2005 and 2024, with an average annual incidence rate of 0.36/100 000. The average annual incidence rate in Minhang District was significantly higher than that in Jinshan District. The most prevalent diseases were malaria and dengue fever, followed by Japanese encephalitis. Monthly case reports were available, predominantly from June to October, with a peak in July-August. A statistically significant difference was observed between the two districts in case distribution during June-October (P＜0.001), whereas no significant difference was found for July-August (P=0.331). The majority of cases were young men (111/229,48.47%), aged 20-39 years. Migrant workers/farmers constituted the largest occupational group (55/229, 24.02%). Registered residents of other provinces and cities (147/229,64.19%), and the main source of infection was overseas importation (112/229,48.91%). There were no statistically significant differences in gender and household-registration composition between the two districts (P＞0.05). Significant differences existed in age, occupation, and source of infection (P＜0.05). The imported diseases were malaria and dengue fever, with Africa and Southeast Asia being the primary source locations. Malaria was the predominant disease imported from other provinces and cities, with cases having been imported from abroad since 2012. Local infections were mainly Japanese encephalitis, followed by malaria (with the last local case reported in 2010). Cases between 2005 and 2009 were predominantly imported from other provinces and cities. The proportion of cases imported from abroad increased sharply after 2010, particularly in Minhang District. Local infections sometimes arise in Jinshan District, with Japanese encephalitis serving as the primary type. Conclusions Incidence rates of parasitic and vector-borne diseases in Minhang and Jinshan districts have generally remained low. To further reduce this disease burden, it will be necessary to strengthen joint measures for prevention and control, eliminate the environmental risk factors of vector organisms, enhance monitoring and precise control of the environment and inbound personnel to prevent the occurrence and transmission of parasitic and vector-borne diseases.

Objective:To explore the high-risk factors affecting the severity of neonatal necrotizing enterocolitis (NEC).Methods:This study involved 153 NEC patients admitted to the Neonatology Department of the Children's Hospital of Soochow University from January 1, 2017, to December 30, 2023. Based on the severity of NEC determined by Bell's criteria, these patients were divided into two groups: mild group (Bell stage Ⅱ, n=70) and severe group (Bell stage Ⅲ, n=83). Clinical data including general conditions, clinical treatment and disease status before the onset of NEC, laboratory test results, and perinatal conditions of the mothers were retrospectively collected. Univariate analysis (rank-sum test and Chi-square test) and multivariate analysis (logistic regression analysis) were used to explore the risk factors affecting the severity of NEC. Results:The proportion of infants with gestational age<37 weeks or birth weight<1 500 g, the rate of antibiotic usage, sepsis or shock were higher in the severe group than in the mild group [91.6% (76/83) vs. 75.7% (53/70); 55.4% (46/83) vs. 34.3% (24/70); 85.5% (71/83) vs. 71.4% (50/70); 55.4% (46/83) vs. 17.1% (12/70); 30.1% (25/83) vs. 8.6% (6/70); with χ 2 values of 7.22, 6.84, 4.57, 23.64, and 10.91, respectively, all P<0.05]. Furthermore, the severe group had a late initiation of breastfeeding and longer durations of peripherally inserted central catheter (PICC) placement and parenteral nutrition [2.00 d (1.00-2.00 d) vs. 1.00 d (1.00-2.00 d); 0.00 d (0.00-18.00 d) vs. 0.00 d (0.00-7.50 d); 14.00 d (5.00-21.00 d) vs. 10.50 d (0.00-18.25 d), with Z values of -2.90, -1.98, and -2.09, respectively, all P<0.05]. (2) Within 48 h before the onset, the severe group had higher proportions of infants with decreased white blood cell count, decreased platelet count, electrolyte imbalance, and metabolic acidosis than the mild group [53.0% (44/83) vs. 14.3% (10/70); 49.4% (41/83) vs. 10.0% (7/70); 38.6% (32/83) vs. 14.3% (10/70); 37.3% (31/83) vs. 14.3% (10/70), with χ2 values of 24.94, 27.38, 11.23, and 10.30, respectively, all P<0.05]. Besides, the levels of procalcitonin and C-reactive protein were higher in the severe group than in the mild group [2.31 ng/ml (0.26-11.71 ng/ml) vs. 0.22 ng/ml (0.00-2.19 ng/ml); 58.50 mg/L (14.34-125.25 mg/L) vs. 8.20 mg/L (0.23-34.56 mg/L), with Z values of -3.88 and -5.02, respectively, both P<0.05]. (3) Multivariate logistic regression analysis showed that prolonged duration of PICC placement, decreased platelet count, electrolyte imbalance, metabolic acidosis, and concurrent sepsis were independent risk factors affecting the severity of NEC [ OR (95% CI) values were 1.104 (1.020-1.196), 5.364 (1.667-17.253), 4.047 (1.171-13.986), 4.333 (1.290-14.556), and 3.290 (1.005-10.774), respectively, with all P<0.05]. Conclusions:Prolonged duration of PICC placement, concurrent sepsis, decreased platelet count, electrolyte imbalance, and metabolic acidosis in NEC patients are more likely to lead to severe cases. In clinical practice, attention should be paid to relevant indicators, and abnormal changes should be identified and intervened in a timely manner to reduce the occurrence of severe NEC.

[Purpose]To analyze the results of breast cancer screening among women aged 45～74 in Chongqing from 2012 to 2022 and compare the risk of breast cancer among women with differ-ent characteristics.[Methods]The Urban Cancer Early Diagnosis and Treatment Program was con-ducted in Chongqing from 2012 to 2022,female residents aged 45～74 years old participated in breast cancer screening.The participants who were assessed as at high risk of breast cancer in the preliminary screening were advised to receive ultrasonography and mammography examination in designated hospitals.The study population was followed up annually to obtain information on their health outcomes.The high risk rate of breast cancer,compliance of further examination,the inci-dence density and breast cancer risk were calculated.[Results]A total of 207 891 women com-pleted the questionnaires survey and risk assessment,and 35 947 were assessed as the individuals with high risk of breast cancer with a high risk rate of 17.29％.Among them 14 713 received the imaging screening with a compliance rate of 40.93％.After a mean follow-up of(5.43±3.01)years,847 cases of breast cancer were diagnosed with a cumulative incidence rate of 407.43/105,an in-cidence density of 75.03/105 person-years(95％CI:70.15/105～80.26/105 person-years).Cox pro-portional hazards regression showed that the risk of breast cancer was higher in obese women than that in normal weight women(HR=1.26,95％CI:1.00～1.59);the risk of breast cancer was signifi-cantly higher in those with family history of breast cancer than that in those without family history(HR=1.69,95％CI:1.36～2.09).Compared with non-high-risk groups of breast cancer,the risk of breast cancer was increased in high-risk individuals who were screened or not screened(HR=1.36,95％CI:1.06～1.73 and HR=1.26,95％CI:1.01～1.56).[Conclusion]The breast cancer screening program combining primary risk assessment with ultrasonography and mammography for the high-risk groups can improve the detection rate,and the compliance rate of imaging screening need to be improved in the future and make accurate screening for people with high risk of breast cancer.

Objective:To analyze the efficacy of endovascular treatment for venous outflow tract obstruction after liver transplantation.Methods:A retrospective analysis was conducted on the data of 7 patients with venous outflow tract obstruction after liver transplantation admitted to Beijing Friendship Hospital, Capital Medical University from November 2020 to December 2024. Among them, there were 5 males and 2 females, with the age of (22.3±8.1) years. The primary diseases included 2 cases of Budd-Chiari syndrome, 1 case of hepatic veno-occlusive disease, 1 case of portal veno-hepatic sinus vascular disease, 1 case of ornithine carbamoyltransferase deficiency, 1 case of primary biliary cirrhosis, and 1 case of autoimmune cirrhosis. Analyze the patient's clinical manifestations, obstruction of venous outflow tract, hemoglobin levels within one week before and one week after the operation, endovascular treatment conditions, and intraoperative complications such as abdominal hemorrhage and vascular injury. Ultrasound was used to measure the depth of ascites and pleural effusion. All patients were followed up immediately after the operation through phone calls or follow-up visits. The clinical symptoms, abdominal vascular ultrasound, enhanced CT and survival status of the patients were followed up.Results:All 7 patients were diagnosed with venous outflow tract obstruction by intraoperative angiography, including 1 cases of inferior vena cava obstruction, 2 cases of hepatic vein obstruction, and 4 cases of vena cava combined with hepatic vein obstruction. A total of 12 endovascular treatments were performed on 7 patients. Among them, 4 patients received balloon dilation and angioplasty once, 1 patient received balloon dilation and angioplasty twice, 1 patient underwent hepatic vein stent implantation after 2 hepatic vein balloon dilation and angioplasty, and 1 patient underwent intrahepatic portosystemic shunt via jugular vein after 2 hepatic vein balloon dilation and angioplasty. The abdominal distensionof the patients were all relieved after the operation, the ascites and pleural effusion decreased, and the edema symptoms of the lower extremities disappeared. There were no intraoperative complications. The preoperative hemoglobin of 7 patients was (113.4±34.0) g/L, and the postoperative hemoglobin was (126.6±34.8) g/L, which increased significantly compared with that before the operation, and the difference was statistically significant ( t=-0.71, P=0.038). Seven patients were followed up for 6 to 24 months, with a median of 12 months. None of them had obvious symptoms including abdominal distension. Abdominal ultrasound and CT indicated that the blood flow of the transplanted liver was unobstructed, and no patient died. Conclusion:Venous outflow tract obstruction after liver transplantation can cause severe symptoms. Endovascular treatment is an effective treatment for venous outflow tract obstruction after liver transplantation.

Objective The aim of this study is to systematically analyze the therapeutic mechanisms of Wuzi Yuye Decoction in diabetic oligoasthenozoospermia based on network pharmacology and animal experiments.Methods Active components and therapeutic targets of Wuzi Yuye Decoction were screened by integrating multiple databases,and their inter-section with diabetic oligoasthenozoospermia-related targets was obtained.Common targets were identified using the Venny platform,and protein-protein interaction(PPI)networks were constructed via the STRING database.And key targets were screened through topological analysis with Cytoscape.Gene Ontology(GO)functional enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses were performed using the DAVID platform.A mouse model of diabetic oligoasthenozoospermia was established by high-fat diet combined with streptozotocin induction,followed by intervention with Wuzi Yuye Decoction.Body weight,testicular index,and sperm quality were assessed,while histopathological changes were evaluated by HE staining and transmission electron microscopy(TEM).In addition,ELISA,oxidative stress assays and Western blot were used to verify the changes in key pathway-related proteins.Results A total of 36 common targets were identified,including key nodes such as TNF,IL6 and IL1B.Enrichment analysis indicated that these targets were sig-nificantly involved in inflammatory responses,oxidative stress,autophagy-apoptosis regulation and reproduction-related pathways.Animal experiments confirmed that Wuzi Yuye Decoction markedly improved testicular mass and sperm motility in diabetic mice,reduced the levels of AGE,TNF-α,IL-6 and IL-1β in testicular tissues,alleviated oxidative stress damage,and restored autophagic flux and blood-testis barrier function by inhibiting the RAGE/NF-κB/mTOR signaling axis.Conclusion Wuzi Yuye Decoction improves the pathological progression of diabetic oligoasthenozoospermia by synergistically modulating multiple targets,including inflammation inhibition,antioxidant effects,autophagy regulation,and related pathways.

Objective:To evaluate the efficacy of 3D printing technology combined with computer navigation-assisted screw implantation in the treatment of atlantoaxial instability (AAI) complicated by vertebral artery anomalies.Methods:A retrospective case series study was conducted to analyze the clinical data of 23 patients with AAI complicated by vertebral artery anomalies who were admitted to Honghui Hospital of Xi′an Jiaotong University between January 2019 and January 2023, including 10 males and 13 females, aged 19-70 years [(51.0±13.3)years]. Vertebral artery anomalies were categorized into unilateral high-riding vertebral artery with unilateral dominance ( n=14), bilateral high-riding vertebral arteries with unilateral dominance ( n=6), and ponticulus posticus ( n=3). All the patients underwent preoperative planning using a 3D-printed model of the atlantoaxial complex with the vertebral artery, followed by posterior atlantoaxial pedicle screw fixation with computer-assisted navigation. Operative duration and intraoperative blood loss were recorded. The accuracy of pedicle screw placement was assessed at 3 days postoperatively using the Gertzbein-Robbins classification. Visual analogue scale (VAS) scores and Japanese Orthopedic Association (JOA) scores were evaluated preoperatively, at 3 days, 3 months postoperatively, and at the last follow-up. Bony fusion was assessed using cervical CT with 3D reconstruction at the last follow-up. Complications were also observed. Results:All the patients were followed up for 12-19 months [(15.1±1.9)months]. The operative duration was 125-167 minutes [(140.6±10.9)minutes] and intraoperative blood loss was 200-600 ml [(295.7±77.8)ml]. At 3 days postoperatively, all the 66 pedicle screws were safely placed, with 60 screws (91%) rated as Gertzbein-Robbins Grade 0 and 6 screws (9%) as Grade 1. At 3 days and 3 months postoperatively, and at the last follow-up, the VAS scores were (4.0±1.0)points, (2.0±0.6)points, and (1.3±0.5)points, and the JOA scores were (14.2±1.2)points, (16.0±0.8)points, and (16.6±0.5)points, both of which were not only significantly improved compared with preoperative (5.6±1.3)points and (12.8±1.5)points, but also further improved over time ( P<0.05). At the last follow-up, 22 patients (96%) achieved satisfactory atlantoaxial bony fusion. No vertebral artery injury, spinal cord or nerve injury, cerebrospinal fluid leakage, or screw loosening were observed in any patients. Conclusion:For patients with AAI complicated by vertebral artery anomalies, 3D printing combined with computer navigation-assisted navigation for atlantoaxial pedicle screw implantation offers multiple advantages, including minimal surgical trauma, high screw placement accuracy, pain relief, neurological function improvement, high fusion rate, and lowered incidence of complications.
