ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ²=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ²=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

Objective To study the relationship between serum Melatonin,macrophage inflammatory pro-tein-1α(MIP-1α)and nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)inflamma-some and prognosis in children with acute respiratory distress syndrome(ARDS).Methods A total of 140 children with ARDS who were admitted to the hospital from January 2021 to January 2023 were enrolled as the ARDS group,and 100 healthy children who underwent physical examination during the same period were enrolled as the control group.According to the clinical outcome on 28 d after admission,the children with ARDS were divided into a death group(29 cases)and a survival group(111 cases).Enzyme-linked immu-nosorbent assay was used to detect the serum levels of Melatonin,MIP-1α,interleukin(IL)-1β,and IL-18.Re-al-time fluorescent quantitative PCR was used to detect the mRNA levels of NLRP3 and Caspase-1.Pearson correlation was used to analyze the correlation between serum levels of Melatonin and MIP-1α and NLRP3 in-flammasome related indicators(NLRP3 mRNA,Caspase-1 mRNA,IL-1β,IL-18)in children with ARDS.Mul-tivariate Cox regression analysis was used to analyze the factors affecting the prognosis of children with ARDS.According to the mean levels of serum Melatonin and MIP-1α,the children with ARDS were divided in-to a high/low Melatonin group and MIP-1α group.The Kaplan-Meier method was used to draw the survival curves of ARDS children with high/low levels of serum Melatonin and MIP-1α.The receiver operating charac-teristic(ROC)curve was used to analyze the predictive value of serum Melatonin and MIP-1α for death in children with ARDS.Results Compared with the control group,the ARDS group had a significantly decreased serum Melatonin level and significantly increased serum MIP-1α,IL-1β,IL-18 and NLRP3 mRNA and Caspase-1 mRNA levels in peripheral blood mononuclear cells(P＜0.05).Pearson correlation analysis showed that the serum Melatonin level of ARDS children was negatively correlated with NLRP3 mRNA,Caspase-1 mRNA,IL-1β and IL-18(P＜0.05),the level of MIP-1α was positively correlated with NLRP3 mR-NA,Caspase-1 mRNA,IL-1β and IL-18(P＜0.05).Multivariate Cox regression analysis showed that acute physiology and chronic health evaluation Ⅱ score,NLRP3 mRNA,Caspase-1 mRNA,IL-1β,IL-18 and MIP-1αwere independent risk factors affecting the prognosis of children with ARDS.Melatonin was an independent protective factor(P＜0.05).Kaplan-Meier survival curve analysis showed that the 28 d survival rate in high Melatonin group was higher than that in low Melatonin group(P＜0.05),and the 28 d survival rate in high MIP-1α group was lower than that in low MIP-1α group(P＜0.05).ROC curve analysis showed that the area under the curve of Melatonin and MIP-1α combined to predict the death of ARDS children was 0.881(95％CI 0.816-0.930).It was higher than 0.785(95％CI 0.708-0.850)and 0.778(95％CI 0.700-0.844)predic-ted by Melatonin or MIP-1α alone.Conclusion The serum Melatonin level is decreased and MIP-1α level is in-creased in children with ARDS,which is closely related to NLRP3 inflammasome and prognosis.Combined de-tection of serum Melatonin and MIP-1α levels has a high predictive value for the prognosis of children with ARDS.

Objective:To evaluate the quality of critical patient handover practice between emergency room and intensive care unit (ICU) nurses, and to provide a basis for structured handover process.Methods:From March to July 2023, a total of 223 pairs of nurses in emergency room and ICU (including EICU) of 5 Class 3 Grade A general hospitals in Suzhou were selected as the research objects by using cross-sectional survey method and convenience sampling method.

Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.

0n December 31,2021,the Chinese Nursing Association released the group standard"nursing care of patients with infusion of vasoactive agents(T/CNAS 22-2021)",which outlines the fundamental requirements for intravenous infusion of vasoactive drugs and standardizes the evaluation,administration,and monitoring.This article provides an interpretation of the key parts and sections of the standard to ensure nursing safety during the administration of vasoactive drugs,aiming to reduce complications.Additionally,it serves as a crucial reference for nurses during the administration of the medication.

BACKGROUND: Ischemic acute kidney injury (AKI) is a common syndrome associated with considerable mortality and healthcare costs. Up to now, the underlying pathogenesis of ischemic AKI remains incompletely understood, and specific strategies for early diagnosis and treatment of ischemic AKI are still lacking. Here, this study aimed to define the transcriptomic landscape of AKI patients through single-cell RNA sequencing (scRNA-seq) analysis in kidneys. METHODS: In this study, scRNA-seq technology was applied to kidneys from two ischemic AKI patients, and three human public scRNA-seq datasets were collected as controls. Differentially expressed genes (DEGs) and cell clusters of kidneys were determined. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, as well as the ligand-receptor interaction between cells, were performed. We also validated several DEGs expression in kidneys from human ischemic AKI and ischemia/reperfusion (I/R) injury induced AKI mice through immunohistochemistry staining. RESULTS: 15 distinct cell clusters were determined in kidney from subjects of ischemic AKI and control. The injured proximal tubules (PT) displayed a proapoptotic and proinflammatory phenotype. PT cells of ischemic AKI had up-regulation of novel pro-apoptotic genes including USP47 , RASSF4 , EBAG9 , IER3 , SASH1 , SEPTIN7 , and NUB1 , which have not been reported in ischemic AKI previously. Several hub genes were validated in kidneys from human AKI and renal I/R injury mice, respectively. Furthermore, PT highly expressed DEGs enriched in endoplasmic reticulum stress, autophagy, and retinoic acid-inducible gene I (RIG-I) signaling. DEGs overexpressed in other tubular cells were primarily enriched in nucleotide-binding and oligomerization domain (NOD)-like receptor signaling, estrogen signaling, interleukin (IL)-12 signaling, and IL-17 signaling. Overexpressed genes in kidney-resident immune cells including macrophages, natural killer T (NKT) cells, monocytes, and dendritic cells were associated with leukocyte activation, chemotaxis, cell adhesion, and complement activation. In addition, the ligand-receptor interactions analysis revealed prominent communications between macrophages and monocytes with other cells in the process of ischemic AKI. CONCLUSION Together, this study reveals distinct cell-specific transcriptomic atlas of kidney in ischemic AKI patients, altered signaling pathways, and potential cell-cell crosstalk in the development of AKI. These data reveal new insights into the pathogenesis and potential therapeutic strategies in ischemic AKI.

Objective:To investigate the predictive value of dynamic electrocardiography (ECG) for myocardial ischemia and arrhythmia in patients with coronary heart disease.Methods:A total of 87 patients with coronary heart disease who received treatment in Wenling Hospital of Traditional Chinese Medicine from January 2020 to January 2022 were included in this study. These patients were divided into a conventional ECG group (group A, n = 40) and a dynamic ECG group (group B, n = 47) according to different examination methods. The detection rate of myocardial ischemia in the two groups was determined. The diagnostic efficacy of routine ECG and dynamic ECG for myocardial ischemia was analyzed according to the results of coronary angiography. The detection rate of arrhythmia was determined in each group. Patient satisfaction was compared between the two groups. Results:There was no significant difference in the total detection rate of myocardial ischemia between the two groups ( P = 0.154). The detection rate of asymptomatic myocardial ischemia in group B [25% (25/47)] was significantly higher than that in group A [10% (10/40), χ2 = 5.24, P = 0.020). According to the results of coronary angiography, the detection rates of myocardial ischemia in group A and group B were 68% (27/40) and 87% (41/47), respectively. The sensitivity, specificity, and accuracy of group B in diagnosing myocardial ischemia were 80% (33/41), [67% (4/6), and 74% (35/47), respectively, all of which were significantly higher than 74% (20/27), [46% (6/13), 68% (27/40) in group A ( χ2 = 8.03, 5.89, 5.03, P = 0.003, 0.012, 0.005). The detection rates of premature ventricular contraction in bi-triplet rhythm, frequent paired premature atrial contraction in bi-triplet rhythm, right bundle-branch block, atrioventricular block, supraventricular tachycardia in group B were significantly higher compared with group A ( χ2 = 10.78, P = 0.001). According to the results of coronary angiography, the detection rates of arrhythmia in groups A and B were 65% (26/40) and 79% (37/47), respectively. The sensitivity, specificity, and accuracy of diagnosing arrhythmia in coronary heart disease in group B were 86% (32/37), 40% (4/10), and 81% (38/47), respectively. The sensitivity and accuracy of diagnosing arrhythmia in coronary heart disease in group B were significantly higher than those in group A [58% (15/26), 55% (22/40), χ2 = 7.30, 4.90, P = 0.005, 0.010). Patient satisfaction in group B [87% (41/47)] was significantly higher than that in group A [65% (26/40), χ2 = 6.24, P = 0.044]. Conclusion:Compared with conventional ECG detection, dynamic ECG has substantially higher detection and diagnosis rates of myocardial ischemia and arrhythmia, as well as a higher patient satisfaction rate, in patients with coronary heart disease, in particular in those with asymptomatic myocardial ischemia.

Objective To analyze and assess the postoperative motor function in children with spastic cerebral palsy (SCP) by surface electromyography (sEMG) and joint angle. Methods Sixteen children with SCP were involved in this study. The sEMG of rectus femoris, biceps femoris, semitendinosus, tibialis anterior, lateral gastrocnemius and medial gastrocnemius muscles and joint angles of the hip, knee and ankle during straight walking were collected preoperatively and postoperatively. In every gait phase, the mean values of joint angles, root mean square and integrated electromyography of sEMG were calculated, to evaluate muscle strength and muscular tension quantitatively. Results The muscle tension of lower limbs was significantly decreased (P<0.05). The muscle strength of rectus femoris and biceps femoris was decreased in the swing phase. At the midswing and terminal swing phase, the strength of tibialis anterior increased significantly (P<0.05). The flexion angle of hip and knee decreased significantly (P<0.05). The dorsiflexion angle of ankle increased significantly (P<0.05), and the varus angle decreased significantly (P<0.05). Conclusions After operation, the crouching gait and clubfoot were improved positively. Therefore, the motor function of children was improved. Combining sEMG and joint angle can evaluate the muscle function of patients quantitatively, and it also can provide references for clinical diagnosis.
