Objective To observe the effect of Huoxin pill （concentrated pill） combined with Baduanjin on the prognosis of patients with acute myocardial infarction complicated by percutaneous coronary intervention （PCI）. Methods 120 patients with acute myocardial infarction complicated with heart failure who received emergency interventional treatment in our hospital from January 2022 to January 2023 were randomly divided into western medicine treatment group and Traditional Chinese Medicine （TCM）comprehensive treatment group. Western medicine treatment: standard western medicine treatment + five prescriptions for cardiac rehabilitation; based on western medicine treatment, Huoxin pill （concentrated pill） combined with Baduanjin therapy was added to the TCM comprehensive treatment group, and the follow-up was 6 months. The observed indexes were exertion angina pectoris scale, Chinese Medicine Syndrome Scale, Chinese medicine syndrome treatment effect evaluation, 6-minute walking test （6MWT）, left ventricular ejection fraction （LVEF）, and brain natriuretic peptide precursor （pro-BNP）. Results Sixty patients were enrolled in the two groups respectively. During the treatment, 2 cases fell off in the western medicine treatment group and 8 cases fell off in the TCM comprehensive treatment group, and a total of 110 cases were enrolled in the group. Compared with the western treatment group, TCM combined therapy significantly improved angina pectoris scale score, TCM Syndrome Scale score, pro-BNP, LVEF and 6MWT （P<0.001）. There were no significant differences in blood routine, liver and kidney function, potassium, blood glucose, blood lipids and cardiac Troponin I （cTnI） between the two groups （P>0.05）. No adverse cardiovascular events occurred during the entire treatment period in both groups. Conclusion Huoxin pill （concentrated pill） combined with Baduanjin was more effective than western therapy in improving LVEF, 6MWT distance, exercise tolerance and cardiac function in patients with acute myocardial infarction complicated with heart failure.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Objective To investigate the current status of delivery room transitional care management for very/extremely preterm infants in Shenzhen City.Methods A cross-sectional survey was conducted in November 2022,involving 24 tertiary hospitals participating in the Shcnzhen Neonatal Data Network.The survey assessed the implementation of transitional care management in the delivery room,including prenatal preparation,delivery room resuscitation,and post-resuscitation management in the neonatal intensive care unit.Very/extremely preterm infants were divided into four groups based on gestational age:＜26 weeks,26-28+6 weeks,29-30+6 weeks,and 31-31+6 weeks.Descriptive analysis was performed on the results.Results A total of 140 very/extremely preterm infants were included,with 10 cases in the＜26 weeks group,45 cases in the 26-28+6 weeks group,49 cases in the 29-30+6 weeks group,and 36 cases in the 31-31+6 weeks group.Among these infants,99(70.7％)received prenatal counseling,predominantly provided by obstetricians(79.8％).The main personnel involved in resuscitation during delivery were midwives(96.4％)and neonatal resident physicians(62.1％).Delayed cord clamping was performed in 52 cases(37.1％),with an average delay time of(45±17)seconds.Postnatal radiant warmer was used in 137 cases(97.9％)for thermoregulation.Positive pressure ventilation was required in 110 cases(78.6％),with 67 cases(60.9％)using T-piece resuscitators and 42 cases(38.2％)using a blended oxygen device.Blood oxygen saturation was monitored during resuscitation in 119 cases(85.0％).The median time from initiating transitional care measures to closing the incubator door was 87 minutes.Conclusions The implementation of delivery room transitional care management for very/extremely preterm infants in the hospitals participating in the Shenzhen Neonatal Data Network shows varying degrees of deviation from the corresponding expert consensus in China.It is necessary to bridge the gap.through continuous quality improvement and multicenter collaboration to improve the quality of the transitional care management and outcomes in very/extremely preterm infants.[Chinese Journal of Contemporary Pediatrics,2024,26(3):250-257]

[摘 要] 目的：探讨补肾健脾方（BSJP）介导法尼醇X受体（FXR）抑制肝癌细胞AH-130诱导的癌性恶病质（CC）大鼠模型的作用及其机制。方法：腹腔注射AH-130细胞建立肝癌CC大鼠模型，实验分为空白对照组、模型对照组、FXR激动剂（CDCA）组、BSJP组和BSJP + CDCA组。建模后，用CDCA、BSJP连续治疗大鼠16 d，每周称量大鼠体质量。实验结束时开腹，取腹主动脉血、粪便及附睾、腹股沟和肩胛区棕色脂肪质量。采用液相色谱-质谱法（LC-MS）检测大鼠血清和粪便中胆汁酸组分及含量，WB、qPCR法检测大鼠空肠、棕色及白色脂肪组织中FXR、Wnt家族成员10b（Wnt10b）、β-连环蛋白（β-catenin）、解偶联蛋白1（UCP-1）的表达。结果：与空白对照组相比，模型对照组大鼠体质量明显降低（P < 0.01）；与模型对照组相比，CDCA、BSJP、BSJP + CDCA组大鼠体质量均增加（均P < 0.01）。与空白对照组相比，模型对照组附睾、腹股沟和肩胛区域及总棕色脂肪质量均上升（均P < 0.05）；与模型对照组相比，各治疗组大鼠附睾、腹股沟区、棕色脂肪质量均下降（均P < 0.05），而肩胛区棕色脂肪组织质量下降无差异（P > 0.05）；各治疗组总棕色脂肪质量均显著下降（P < 0.05或P < 0.01）。LC-MS分析显示，各组大鼠血清及粪便中胆汁酸组成及含量均发生改变。qPCR、WB法结果证实，与模型组相比，BSJP和BSJP + CDCA可促进大鼠回肠、棕色脂肪及白色脂肪组织中FXR mRNA和蛋白表达升高（均P < 0.05），Wnt10b、β-catenin、UCP-1 mRNA和蛋白表达均下降（均P < 0.05）。结论：BSJP能够抑制肝癌AH-130细胞诱导的大鼠CC，并减轻由此引起的体质量下降和棕色脂肪组织的形成，其机制可能涉及调控FXR并通过抑制棕色脂肪中与Wnt通路相关的Wnt10b、β-catenin和UCP-1的表达来实现。

Background/Aims: Nonalcoholic fatty liver disease (NAFLD) is associated with a multitude of adverse outcomes. We aimed to estimate the pooled incidence of NAFLD-related adverse events. Methods: We performed a systematic review and meta-analysis of cohort studies of adults with NAFLD to evaluate the pooled incidence of adverse events. Results: 19,406 articles were screened, 409 full-text articles reviewed, and 79 eligible studies (1,377,466 persons) were included. Mean age was 51.47 years and body mass index 28.90 kg/m2. Baseline comorbidities included metabolic syndrome (41.73%), cardiovascular disease (CVD) (16.83%), cirrhosis (21.97%), and nonalcoholic steatohepatitis (NASH) (58.85%). Incidence rate per 1,000 person-years for mortality included: all-cause (14.6), CVD-related (4.53), non-liver cancer-related (4.53), and liver-related (3.10). Incidence for liver-related events included overall (24.3), fibrosis progression (49.0), cirrhosis (10.9), liver transplant (12.0), and hepatocellular carcinoma (HCC) (3.39). Incidence for non-liver events included metabolic syndrome (25.4), hypertension (25.8), dyslipidemia (26.4), diabetes (19.0), CVD (24.77), renal impairment (30.3), depression/anxiety (29.1), and non-liver cancer (10.5). Biopsy-proven NASH had higher incidence of HCC (P=0.043) compared to non-NASH. Higher rates of CVD and mortality were observed in North America and Europe, hypertension and non-liver cancer in North America, and HCC in Western Pacific/Southeast Asia (P<0.05). No significant differences were observed by sex. Time-period analyses showed decreasing rates of cardiovascular and non-liver cancer mortality and increasing rates of decompensated cirrhosis (P<0.05). Conclusions People with NAFLD have high incidence of liver and non-liver adverse clinical events, varying by NASH, geographic region, and time-period, but not sex.

Background/Aims: Ineffective esophageal motility (IEM) is common in patients with gastroesophageal reflux disease (GERD) and can be associated with poor esophageal contraction reserve on multiple rapid swallows. Alterations in the esophageal microbiome have been reported in GERD, but the relationship to presence or absence of contraction reserve in IEM patients has not been evaluated. We aim to investigate whether contraction reserve influences esophageal microbiome alterations in patients with GERD and IEM. Methods: We prospectively enrolled GERD patients with normal endoscopy and evaluated esophageal motility and contraction reserve with multiple rapid swallows during high-resolution manometry. The esophageal mucosa was biopsied for DNA extraction and 16S ribosomal RNA gene V3-V4 (Illumina)/full-length (Pacbio) amplicon sequencing analysis. Results: Among the 56 recruited patients, 20 had normal motility (NM), 19 had IEM with contraction reserve (IEM-R), and 17 had IEM without contraction reserve (IEM-NR). Esophageal microbiome analysis showed a significant decrease in microbial richness in patients with IEM-NR when compared to NM. The beta diversity revealed different microbiome profiles between patients with NM or IEM-R and IEM-NR (P = 0.037). Several esophageal bacterial taxa were characteristic in patients with IEM-NR, including reduced Prevotella spp.and Veillonella dispar, and enriched Fusobacterium nucleatum. In a microbiome-based random forest model for predicting IEM-NR, an area under the receiver operating characteristic curve of 0.81 was yielded. Conclusions In symptomatic GERD patients with normal endoscopic findings, the esophageal microbiome differs based on contraction reserve among IEM. Absent contraction reserve appears to alter the physiology and microbiota of the esophagus.

Radiation recall pneumonitis is an inflammatory reaction of previously radiated lung parenchyma triggered by systemic pharmacological agents (such as chemotherapy and immunotherapy) or vaccination. Patients present with non-specific symptoms such as cough, shortness of breath, or hypoxia soon after the initiation of medication or vaccination. Careful assessment of the patient’s history, including the thoracic radiation treatment plan and timing of the initiation of the triggering agent, in conjunction with CT findings, contribute to the diagnosis. Once a diagnosis is established, treatment includes cessation of the causative medication and/or initiation of steroid therapy. Differentiating this relatively rare entity from other common posttherapeutic complications in oncology patients, such as recurrent malignancy, infection, or medication-induced pneumonitis, is essential for guiding downstream clinical management.

Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.
