Objective:To explore the impact of the two-way referral model on compliance and prognosis in patients with heart failure.Methods:This bidirectional cohort study enrolled chronic heart failure (CHF) patients treated at Qilu Hospital of Shandong University or designated primary hospitals between March 2018 and March 2022. Patients were categorized into two groups based on referral status: two-way referral group (participating in the referral model with≥1 follow-up visit at primary hospitals) and the core hospital group (receiving treatment and follow-up exclusively at Qilu Hospital). Baseline clinical characteristics were collected and compared between groups. Patients underwent followed-up, with primary endpoints including follow-up rate, drug (β-blockers, angiotension converting enzyme inhibitor (ACEI)/angiotensin Ⅱ receptor blockers (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists) utilization rate and target dose achievement rate. Secondary endpoints encompassed changes from baseline in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), and N-terminal pro-brain natriuretic peptide (NT-proBNP), plus cardiovascular mortality and heart failure rehospitalization. Generalized linear mixed models analyzed longitudinal trends in LVEF, LVEDd, and NT-proBNP levels. Kaplan-Meier curves and Cox regression evaluated LVEF recovery rates, supplemented by subgroup analyses. Multivariate logistic regression was used to identify factors influencing target dose achievement rate for β-blockers and ACEI/ARB/ARNI therapies in CHF patients.Results:A total of 357 patients were enrolled, aged 53 (41, 63) years, including 256 males (71.7%). 157 patients were in the two-way referral group and 200 patients in the core hospital-treated group. Compared with the core hospital-treated group, the two-way referral group had lower baseline LVEF (28 (22, 34)% vs. 31 (23, 36)%, P=0.021) and systolic blood pressure (116 (104, 125) mmHg vs. 121 (109, 134) mmHg (1 mmHg=0.133 kPa), P=0.010). The 12-month follow-up rate of the two-way referral group was higher than the core hospital-treated group (73.8% vs. 56.0%, P=0.004). No significant between-group differences were observed in drug utilization rate of β-blockers, ACEI/ARB/ARNI, or sodium-glucose cotransporter 2 inhibitors during follow-up (all P>0.05), while mineralocorticoid receptor antagonists use showed a declining trend in both groups. Although the core hospital-treated group had higher target dose achievement rates for β-blockers (65.4% vs. 49.3%, P=0.042) and ACEI/ARB/ARNI (79.8% vs. 65.8%, P=0.046) than the two-way referral group, multivariate logistic regression indicated that the two-way referral model was not a negative predictor for these outcomes (all P>0.05). Both groups showed improved NT-proBNP, LVEDd, and LVEF from baseline (all P<0.001) with no significant difference in trends between groups (all P>0.05). There was no significant difference in the composite incidence (7.6% vs. 6.5%, P=0.674) and cumulative incidence (log-rank P=0.684) of cardiovascular death and heart failure rehospitalization at 12 months between two groups. Conclusion:The two-way referral model demonstrates advantages in improving medication adherence, drug utilization rates, and targetdoseachievement rates among CHF patients. This model not only promotes cardiac functional recovery but also reduces risks of cardiovascular mortality and heart failure rehospitalization, achieving comparable therapeutic and management outcomes to those observed in core hospital-treated patients.

This paper summarized the experience of Chinese medical master Han Mingxiang in treating pathogenic-damp caused diseases by the method of dispelling dampness.Han Mingxiang believes that refractory diseases are usually caused by pathogenic cold and dampness,and complicated diseases are usually caused by phlegm and stagnation.Predominant dampness causes the inactivation of yang,and warming therapy is not the only one choice for activating yang.In clinical practice,he emphasizes the principles for dispelling dampness mainly by simultaneous treatment of phlegm and qi,lifting lucid yang and lowering turbid yin,nourishing spleen and resolving dampness,expelling and resolving pathogens by elevation and dispersion,relieving exterior and activating yang,which is summed up as"warming,resolving,dispersing and activating,regulating qimovement".For the treatment of the diseases caused by pathogenic-damp,the warm-natured medicines are usually used frequently,and the warm-natured medicines are not limited to the pungent-warm medicine.For dispelling dampness,the method of relieving exterior and promoting qi movement,percolating and draining dampness with aromatics,and relieving fluid retention with pungent-sweet medicine can be chosen flexibly based on syndrome differentiation,thus to reach the goal of activating yang and resolving stagnation and to obtain satisfactory efficacy.

Objective:To investigate the risk factors of colorectal adenomatous polyps.Methods:The clinical data of 395 patients who underwent colonoscopy in the Tongzhou branch, Tongzhou District, Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from August 2017 to August 2021 were analyzed. According to the examination results, adenomatous polyps were divided into adenomatous polyps group (193 cases) and non-polyp group (202 cases). The risk factors of colorectal adenomatous polyps were screened by univariate analysis and multivariate logistic regression analysis.Results:The results of single factor analysis suggested that: body mass index (BMI), sex, age, proportion of blood type A, history of large intestine polyps, history of Helicobacter pylori (Hp) infection, history of alcohol consumption, history of smoking, proportion of heavy oil diet, history of oral calcium, history of oral statins, history of oral non-steroidal anti-inflammatory drugs, history of oral antibiotics, and high fat diet (pork, beef, and animal organs), high salt diet, love of pickled food, love of sweet food, love of greasy, good mood, anxiety, depression, impatience and irritability, history of hypertension, diabetes and hyperlipidemia were statistically significant in the adenomatous polyp group and the non-polyp group (all P<0.05). Factors with P<0.05 in the above single factor analysis were taken as independent variables, and the incidence of disease was taken as dependent variable for multi-factor logistic regression analysis. The results showed that BMI, age, blood type A, Hp infection history, drinking history, smoking history, oral non-steroidal anti-inflammatory drugs history, oral antibiotics history, high salt diet, good mood, hypertension were the influencing factors for the incidence of adenomatous polyps (all P<0.05). Conclusions:High BMI, old age, blood type A, history of Hp infection, smoking history, oral non-steroidal anti-inflammatory drug history, oral antibiotics history, high salt diet and hypertension are risk factors for the development of adenomatous polyps. Drinking alcohol and good mood can reduce the risk of colorectal adenomatous polyps. Therefore, targeted intervention measures can be formulated for high-risk patients to reduce the risk of colorectal adenomatous polyps.

Objective:To explore the clinical phenotype and genetic basis of a child with Neutral lipid storage disease with myopathy (NLSDM).Methods:A child who was admitted to the First Affiliated Hospital of Zhengzhou University in February 2021 for a history of elevated creatine kinase (CK) for over 2 months was selected as the study subject. Clinical and laboratory examinations were carried out, and the child was subjected to whole exome sequencing. Candidate variants were validated by Sanger sequencing of her family members.Results:The patient, a 9-year-old female, had exhibited weakness in the lower limbs, elevated CK level, and refractory cardiomyotrophy. Genetic testing revealed that she has harbored c. 32C>G (p.S11W) and c. 516C>G (p.N172K) compound heterozygous variants of the PNPLA2 gene, which were respectively inherited from her mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were rated as likely pathogenic (PM1+ PM2_Supporting+ PP3+ PP4). Conclusion:The c. 32C>G (p.S11W) and c. 516C>G (p.N172K) compound heterozygous variants of the PNPLA2 gene probably underlay the myasthenia gravis and elevated creatine kinase in this child.

Background::Clinical opportunistic screening is a cost-effective cancer screening modality. This study aimed to establish an easy-to-use diagnostic model serving as a risk stratification tool for identification of individuals with malignant gastric lesions for opportunistic screening.Methods::We developed a questionnaire-based diagnostic model using a joint dataset including two clinical cohorts from northern and southern China. The cohorts consisted of 17,360 outpatients who had undergone upper gastrointestinal endoscopic examination in endoscopic clinics. The final model was derived based on unconditional logistic regression, and predictors were selected according to the Akaike information criterion. External validation was carried out with 32,614 participants from a community-based randomized controlled trial.Results::This questionnaire-based diagnostic model for malignant gastric lesions had eight predictors, including advanced age, male gender, family history of gastric cancer, low body mass index, unexplained weight loss, consumption of leftover food, consumption of preserved food, and epigastric pain. This model showed high discriminative power in the development set with an area under the receiver operating characteristic curve (AUC) of 0.791 (95% confidence interval [CI]: 0.750–0.831). External validation of the model in the general population generated an AUC of 0.696 (95% CI: 0.570–0.822). This model showed an ideal ability for enriching prevalent malignant gastric lesions when applied to various scenarios.Conclusion::This easy-to-use questionnaire-based model for diagnosis of prevalent malignant gastric lesions may serve as an effective prescreening tool in clinical opportunistic screening for gastric cancer.

Objective To investigate the effect and possible mechanism of Qili Qiangxin Capsule on the en-dothelial mesenchymal transition of myocardial cells in mice with heart failure after myocardial infarction.Methods A total of 21 male C57BL/6 mice aged 6-8 weeks were divided into a normal control group,a drug control group(normal mice were treated with high-dose Qili Qiangxin Capsule),and a heart failure model group.The heart failure model group was divided into a positive drug control group[microRNA21(miR-21)inhibitor intervention],high,medium,and low dose Qili Qiangxin Capsule intervention groups,a total of seven groups.The heart failure model group underwent ligation of the left anterior descending coronary artery,while the normal control group and the drug control group underwent the same surgical procedure as the model group,but left anterior descending coronary artery ligation was not performed.A small animal ultrasound ima-ging system was used to detect hemodynamic parameters in mice.HE staining was used to observe pathologi-cal changes in mouse myocardium.Sirius red staining was used to detect myocardial tissue fibrosis in mice.Wheat-germ agglutinin staining was used to evaluate the degree of myocardial cell enlargement.Enzyme linked immunosorbent assay(ELISA)was used to detect the expression of N-terminal pro brain natriuretic peptide(NT-proBNP)and cardiac troponin I(cTnⅠ)in mouse serum heart failure markers,as well as the expression levels of activator protein-1(AP-1)and transforming growth factor-β1(TGF-β1)in mouse myocardial tissue.Real time fluorescence quantitative PCR(qRT-PCR)was used to detect the expression level of miR-21 in pe-ripheral blood of mice.Western blot was used to detect CD31 and VE-cadherin in mouse myocardial tissue,and immunohistochemistry was used to detect the expression levels of a-smooth muscle actin(a-SMA),iron death inhibitory protein 1(FSP1),bone morphogenetic protein 7(BMP7),TGF-β1,Smad2/3,and p-Smad2/3 pro-teins.Results Qili Qiangxin Capsule significantly improved heart function and myocardial tissue pathological damage in heart failure mice,reduced myocardial tissue fibrosis levels,alleviated compensatory hypertrophy of non infarcted myocardial cells,inhibited endothelial mesenchymal transition in myocardial tissue,decreased the expression of miR-21,TGFβ1,a-SMA,FSP1 and Smad2/3,and increased the expression of BMP7,VE-cadher-in,and CD31.Conclusion Qili Qiangxin Capsule may improve myocardial injury in mice with heart failure caused by myocardial infarction by regulating the expression of miR-21 and affecting the downstream TGF-β1/Smad2/3 signaling pathway.
