Wastewater-based epidemiology has emerged as a transformative surveillance tool for estimating substance consumption and monitoring disease prevalence, particularly during the COVID-19 pandemic. It enables the population-level monitoring of illicit drug use, pathogen prevalence, and environmental pollutant exposure. In this perspective, we summarize the key challenges specific to the Chinese context: (1) Sampling inconsistencies, necessitating standardized 24-hour composite protocols with high-frequency autosamplers (≤ 15 min/event) to improve the representativeness of samples; (2) Biomarker validation, requiring rigorous assessment of excretion profiles and in-sewer stability; (3) Analytical method disparities, demanding inter-laboratory proficiency testing and the development of automated pretreatment instruments; (4) Catchment population dynamics, reducing estimation uncertainties through mobile phone data, flow-based models, or hydrochemical parameters; and (5) Ethical and data management concerns, including privacy risks for small communities, mitigated through data de-identification and tiered reporting platforms. To address these challenges, we propose an integrated framework that features adaptive sampling networks, multi-scale wastewater sample banks, biomarker databases with multidimensional metadata, and intelligent data dashboards. In summary, wastewater-based epidemiology offers unparalleled scalability for equitable health surveillance and can improve the health of the entire population by providing timely and objective information to guide the development of targeted policies.

Objective To evaluate the effect of tirofiban injection in coronary artery occlusion by suction catheter on the opening time of the coronary artery occlusion , the improvement of the blood flow and the incidence of adverse events in 30 days. Methods A total of 97 patients with acute myocardial infarction in recent 4 years were included , whose culprit vessels were subtotal occlusion or total occlusion by angiography and were randomly divided into thrombus aspiration group (group A) and tirofiban injection in occlusion and thrombus aspiration group (group B). The opening time of the coronary artery, the improvement of the blood flow and the incidence of adverse events in 30 days were compared between two groups. Results The opening time of the coronary artery occlusion in group A was shortened when compared with group B but the blood flow arriving TIMI III grade in group B was shorter (P < 0.05). No-reflow incidence in group B was lower while the proportion of blood flow arriving TIMI III grade was higher than that in group A in early phase (P < 0.05). The incidence of adverse events in 30 days was decreased in group B when compared with group A ,but the difference wasn't statistically significant (P > 0.05). Conclusion Direct tirofiban injection in coronary artery occlusion could effectively shorten the opening time of the coronary artery occlusion reduce no-reflow incidence , and improve coronary perfusion but could not decrease the incidence of adverse cardiovascular events in 30 days.

Objective:To explore the relationship between thyroid function and cardiovascular diseases .Methods:A total of 980 patients undergoing thyroid function examination during hospitalization were selected . According to their thyroid function ,they were divided into normal thyroid function group (normal group ,n= 930) , hyperthy-roidism group (n=18) ,and hypothyroidism group (n=32) .Clinical data were analyzed ,blood lipids and coagula-tion function indexes were examined and compared among three groups . Results:Compared with normal group ,the incidence rate of atrial fibrillation significantly rose ,incidence rate of hypertension ,cardiac insufficiency signifi-cantly reduced;levels of TC、TG、 LDL-C、 HDL-C significantly reduced ,activated partial thromboplastin time significantly extended in hyperthyroidism group , P<0.01 all;incidence rate of coronary heart disease significantly rose ,levels of TG、HDL-C significantly rose ,levels of TC 、LDL-C significantly reduced in hypothyroidism group , P<0.01 all;Compared with hyperthyroidism group ,the incidence rate of hypertension ,coronary heart disease sig-nificantly rose ,atrial fibrillation significantly reduced ,P<0.05 or <0.01 ;levels of TG、LDL-C、HDL-C signifi-cantly rose ,TC level significantly reduced in hypothyroidism group , P<0. 01 all .Conclusion:Thyroid function is closely related to cardiovascular diseases .so it′s suggested that thyroid function detection should be regarded as a routine examination in patients with cardiovascular diseases and a follow-up index for those with thyroid dysfunc-tion .

The cardiovascular ion channel disease is one of the main among ion channel diseases.It plays the important effect of cardiovascular disease.Ion channel diseases are responsible for almost all arrhythmias and sudden cardiac death.This text reviews genetic and acquired cardiac ion channel diseases,and associated treatments are introduced briefly.
