Objective To evaluate the performance of the artificial intelligence (AI)-enabled snail identification system for recognition of Oncomelania hupensis robertsoni and Tricula in schistosomiasis-endemic areas of Yunnan Province. Methods Fifty O. hupensis robertsoni and 50 Tricula samples were collected from Yongbei Township, Yongsheng County, Lijiang City, a schistosomiasis-endemic area in Yunnan Province in May 2024. A total of 100 snail sample images were captured with smartphones, including front-view images of 25 O. hupensis robertsoni and 25 Tricula samples (upward shell opening) and back-view images of 25 O. hupensis robertsoni and 25 Tricula samples (downward shell opening). Snail samples were identified as O. hupensis robertsoni or Tricula by schistosomiasis control experts with a deputy senior professional title and above according to image quality and morphological characteristics. A standard dataset for snail image classification was created, and served as a gold standard for recognition of snail samples. A total of 100 snail sample images were recognized with the AI-enabled intelligent snail identification system based on a WeChat mini program in smartphones. Schistosomiasis control professionals were randomly sampled from stations of schistosomisis prevention and control and centers for disease control and prevention in 18 schistosomiasis-endemic counties (districts, cities) of Yunnan Province, for artificial identification of 100 snail sample images. All professionals are assigned to two groups according the median years of snail survey experiences, and the effect of years of snail survey experiences on O. hupensis robertsoni sample image recognition was evaluated. A receiver operating characteristic (ROC) curve was plotted, and the sensitivity, specificity, accuracy, Youden’s index and the area under the curve (AUC) of the AI-enabled intelligent snail identification system and artificial identification were calculated for recognition of snail sample images. The snail sample image recognition results of AI-enabled intelligent snail identification system and artificial identification were compared with the gold standard, and the internal consistency of artificial identification results was evaluated with the Cronbach’s coefficient alpha. Results A total of 54 schistosomiasis control professionals were sampled for artificial identification of snail sample image recognition, with a response rate of 100% (54/54), and the accuracy, sensitivity, specificity, Youden’s index, and AUC of artificial identification were 90%, 86%, 94%, 0.80 and 0.90 for recognition of snail sample images, respectively. The overall Cronbach’s coefficient alpha of artificial identification was 0.768 for recognition of snail sample images, and the Cronbach’s coefficient alpha was 0.916 for recognition of O. hupensis robertsoni snail sample images and 0.925 for recognition of Tricula snail sample images. The overall accuracy of artificial identification was 90% for recognition of snail sample images, and there was no significant difference in the accuracy of artificial identification for recognition of O. hupensis robertsoni (86%) and Tricula snail sample images (94%) (χ² = 1.778, P > 0.05). There was no significant difference in the accuracy of artificial identification for recognition of snail sample images with upward (88%) and downward shell openings (92%) (χ² = 0.444, P > 0.05), and there was a significant difference in the accuracy of artificial identification for recognition of snail sample images between schistosomiasis control professionals with snail survey experiences of 6 years and less (75%) and more than 6 years (90%) (χ² = 7.792, P < 0.05). The accuracy, sensitivity, specificity and AUC of the AI-enabled intelligent snail identification system were 88%, 100%, 76% and 0.88 for recognition of O. hupensis robertsoni snail sample images, and there was no significant difference in the accuracy of recognition of O. hupensis robertsoni snail sample images between the AI-enabled intelligent snail identification system and artificial identification (χ² = 0.204, P > 0.05). In addition, there was no significant difference in the accuracy of artificial identification for recognition of snail sample images with upward (90%) and downward shell openings (86%) (χ² = 0.379, P > 0.05), and there was a significant difference in the accuracy of artificial identification for recognition of snail sample images between schistosomiasis control professionals with snail survey experiences of 6 years and less and more than 6 years (χ² = 5.604, P_adjusted < 0.025). Conclusions The accuracy of recognition of snail sample images is comparable between the AI-enabled intelligent snail identification system and artificial identification by schistosomiasis control professionals, and the AI-enabled intelligent snail identification system is feasible for recognition of O. hupensis robertsoni and Tricula in Yunnan Province.

Disrupted bone morphogenetic protein type 2 receptor (BMPR2) signaling in endothelial cells drives pulmonary arterial hypertension (PAH). However, targeted recovery of this signaling pathway by lipid nanoparticles (LNPs) has not been explored as a therapy. Here, we employed Design of Experiments to optimize the delivery efficiency of LNPs targeting pulmonary endothelial cells developed by our laboratory, resulting in a remarkable 35-fold increase in a simplified three-component formulation without helper lipids. Administration of BMPR2 mRNA LNPs effectively reversed established PAH in two experimental rat models (monocrotaline or SU5416-hypoxia) by reversing pulmonary vascular remodeling. Specifically, BMPR2 mRNA LNPs replenished the expression of BMPR2 protein and subsequently activated downstream pathways, as confirmed by elevated levels of p-SMAD1/5/9 and ID1 proteins. The relief of pulmonary arterial occlusion was demonstrated by thinned pulmonary arterial media and decreased proportion of full muscularized vessels. Alleviation of right ventricular hypertrophy was indicated by declined Fulton index, the cross-sectional area of right ventricular cardiomyocytes as well as collagen deposition. Effective recovery of right ventricular function was evidenced by increased pulmonary artery flow acceleration time/pulmonary artery flow ejection time ratio. These findings underscore the potential of restoring BMPR2 signaling through pulmonary endothelial cell-specific LNPs for treating PAH.

OBJECTIVES: To analyze the differential expression and biological functions of circRNAs in the anterior lens capsules of high myopic patients with cataract and their pathogenic roles in the development of this condition. METHODS: Anterior lens capsule specimens were collected intraoperatively from 36 patients with age-related cataract (ARC) and 36 high myopic patients with cataract. Among these, 18 specimens from each group were selected for whole transcriptome sequencing and biological analysis, and the remaining 36 specimens were used for validation of circPDGFRA, circFOXJ3, hsa_circ_0004767, hsa_circ_0007528, ciCRIM1, circMAN1A2, circSLC5A3, and circPTK2 expressions using RT-qPCR. hsa_circ_0007528 was selected for cell experiments to examine its effects on proliferation, migration, and apoptosis of lens epithelial cells (LECs). RESULTS: A total of 16 192 circRNAs were detected in the specimens from both groups, among which 62 circRNAs were differentially expressed (29 upregulated and 33 downregulated). GO and KEGG analyses revealed that the differentially expressed circRNAs were primarily localized in the cytoplasm, nucleoplasm, and endoplasmic reticulum, and were involved in signaling pathways associated with Gap junction and the PI3K-Akt, NF-κB, Jak-STAT, HIF-1, and MAPK signaling pathways. The ceRNA network predicted multiple target genes. RT-qPCR validation results were consistent with the sequencing data. In the LECs, upregulation of hsa_circ_0007528 significantly inhibited cell proliferation and migration and obviously promoted cell apoptosis. CONCLUSIONS The expression profile of circRNAs in the anterior lens capsule of high myopic patients with cataract differs from that of ARC patients. Upregulation of hsa_circ_0007528 inhibits LEC proliferation and migration and promotes cell apoptosis.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective To investigate the expression and prognostic value of serum receptor for advanced glycation end products(RAGE)and CXC-chemokine ligand 16(CXCL16)in patients with sepsis complicated with acute respiratory distress syndrome(ARDS).Methods A total of 234 patients with sepsis diagnosed and treated in a hospital from January 2019 to January 2022 were selected as the study subjects,and were divided into 82 patients with sepsis complicated with ARDS(ARDS group)and 152 patients with sepsis without ARDS(non-ARDS group)according to whether the subjects were complicated with ARDS.ARDS group was divided into survival group(n=50)and death group(n=32)according to the survival status within 28 days of admission.Another 60 healthy subjects who underwent physical examination in the same period were se-lected as the control group.Serum RAGE and CXCL16 levels were detected by enzyme-linked immunosorbent assay.Pearson correlation analysis of serum RAGE and CXCL16 levels with sequential organ failure assess-ment(SOFA)score,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and oxygenation index in patients with sepsis and ARDS.Multivariate Logistic regression analysis of prognostic factors of sep-sis complicated with ARDS.The predictive value of serum RAGE and CXCL16 on the prognosis of sepsis complicated with ARDS patients was analyzed by receiver operating characteristic curve.Results The serum RAGE and CXCL16 levels in ARDS group were higher than those in non-ARDS group and control group,and the serum RAGE and CXCL16 levels in non-ARDS group were higher than those in control group,the differ-ence was statistically significant(P＜0.05).Compared with the survival group,the mechanical ventilation time,intensive care unit stay time,procalcitonin,SOFA score,APACHE Ⅱ score,serum RAGE,CXCL16 lev-els were higher in the death group,and the oxygenation index was lower,with statistical significance(all P＜0.05).The serum RAGE level in patients with sepsis complicated with ARDS was positively correlated with SOFA score and APACHE Ⅱ score(r=0.603,0.671,P＜0.05).Serum CXCL16 levels were positively corre-lated with SOFA score and APACHE Ⅱ score(r=0.655,0.707,P＜0.05).Serum RAGE and CXCL16 were negatively correlated with oxygenation index(r=-0.712,-0.683,P＜0.05).Multi-factor Logistics regres-sion analysis showed that serum RAGE and CXCL16 were independent risk factors for death within 28 days of admission in patients with sepsis complicated with ARDS.The area under the curve(AUC)of combined de-tection of serum RAGE and CXCL16 for predicting death within 28 days of admission in patients with sepsis complicated with ARDS was 0.882,which was higher than that of single index detection of serum RAGE and CXCL16,and the difference was statistically significant(Z=4.450,4.906,P＜0.05).Conclusion The com-bined detection of serum RAGE and CXCL16 is helpful to evaluate the clinical prognosis of sepsis complicated with ARDS patients.

Blinding is an important means to control and reduce measurement bias in clinical research， and blinding assessment is the main method to measure the success of the blinding method. By summarizing the current situation of blinding assessment in randomized controlled trials （RCT） of acupuncture， it was found that the report rate of blinding assessment by acupuncture RCT was relatively low， and the studies reporting blinding assessment had several problems， such as incomplete assessment individuals， unreasonable assessment questionnaires， and unscientific analysis methods， and the setting of the assessment time point is controversial. Given the above problems， this paper discussed the key elements of blinding assessment individuals， assessment questionnaires， assessment time points， and analysis methods. It is suggested that blinding assessment should be carried out on all blinded participants and personnel in the study； the assessment questionnaire should be designed by direct inquiry， with responses designed using three or more categorical options that include an "unclear" option； the early stage of the trial should be taken as the mandatory time point for assessment， integrating the evaluation index of the James blinding index and the Bang blinding index， in order to standardize the application of blinding assessment in acupuncture RCT and improve the quality of acupuncture clinical research.

Objective:To investigate the prevalence and associated risk of cardiovascular event of resistant hypertension in treated outpatients.Methods:This study was a nationwide multi-center prospective cohort study. The participants were treated outpatients enrolled in the China Nationwide Ambulatory and Home Blood Pressure Registry study of 42 hospitals in 19 provinces across the country from August 2009 to October 2017. Apparent resistant hypertension was defined as uncontrolled office blood pressure (≥140/90 mmHg, 1 mmHg=0.133 kPa) in spite of the use of three antihypertensive drugs or controlled office blood pressure (<140/90 mmHg) with four antihypertensive drugs or more. Subjects diagnosed with uncontrolled office blood pressure were further subdivided as pseudo-resistant hypertension and true resistant hypertension based on 24 h ambulatory blood pressure monitoring. The primary endpoint was fatal and non-fatal cardiovascular and cerebrovascular events, which was a composite endpoint consisting of cardiovascular and cerebrovascular death, ischemic and hemorrhagic stroke, myocardial infarction, coronary artery revascularization, unstable angina, heart failure, and coronary artery stenosis≥50% confirmed by coronary angiography. Secondary outcomes included fatal and non-fatal stroke or cardiac events. Patients with controlled office blood pressure after taking only 1 or 2 antihypertensive drugs were included as control. Kaplan-Meier survival curves, log-rank test, and Cox proportional risk model were used to evaluate the risk of apparent refractory hypertension in relation to cardiovascular and cerebrovascular prognosis.Results:A total of 2 782 treated hypertensive patients, aged (58.1±12.3) years were enrolled, including 1 403 (50.4%) men. The prevalence of apparent and true resistant hypertension was 15.1% (420/2 782) and 10.5% (293/2 782), respectively. Among patients with apparent resistant hypertension, during a median of 5 years follow-up, the cumulative incidence rate was 28.2, 11.2 and 19.1 per 1 000 person-years for fatal and non-fatal cardiovascular events ( n=58), stroke ( n=24) and cardiac events ( n=40), respectively. The Kaplan-Meier curve and log-rank test showed that those patients with true resistant hypertension, had the highest cumulative incidence rate of fatal and non-fatal cardiovascular events, stroke, and cardiac events. Multivariable Cox regression analyses showed that true resistant hypertension was associated with a significantly higher risk of fatal and non-fatal cardiovascular events ( HR=1.73, 95% CI 1.17-2.56, P=0.006) and stroke ( HR=2.81, 95% CI 1.53-5.17, P=0.001). Conclusion:Resistant hypertension, especially true resistant hypertension, is associated with a higher risk of fatal and non-fatal cardiac and cerebrovascular events.
