Objective:To assess the predictive accuracy and practical utility of established risk prediction models for enteral nutrition intolerance in critically ill patients. Methods:A meta-analysis was conducted to identify existing risk prediction models for enteral nutrition intolerance in critically ill patients. Eligible patients admitted to the Department of Critical Care Medicine and various ICUs of General Hospital of Eastern Theater Command from March 2023 to August 2023, meeting natriuresis criteria, were included in the study. The discrimination and calibration of the two models were assessed using the area under the receiver operating characteristic curve (AUROC) and the Hosmer-Lemeshow goodness-of-fit test (H-L test). Results:Two models were analyzed, encompassing a total of 395 patients, among whom 161 experienced intolerances, resulting in an incidence rate of 40.8％. Model 1 demonstrated an AUROC of 0.838 (95％CI:0.798 ～ 0.873), while model 2 yielded an AUROC of 0.744 (95％CI:0.698 ～ 0.786). The Delong method was utilized to compare the AUROC values of the two models, revealing a statistically significant difference (P=0.0043). Notably, the model 1 exhibited superior performance compered to model 2. The H-L test for model 1 indicated fair calibration (X2=61.116, P<0.001), whereas model 2 demonstrated better calibration (X2=3.659, P=0.887). Conclusion:Model 1 exhibits superior discriminatory ability compared tomodel 2, while the calibration of model 2 surpasses that of model 1. Model 1 is well-suited for dynamic prediction, accommodating changes in patient condition over time. Conversely, Model 2 is appropriated for initial prediction following enteral nutrition initiation. Healthcare professionals can integrate bothmodels based on the specific clinical conditions to enhance predictive accutacy. Additionally, they can undertake high-quality research to develop a novel risk prediction model.

Objective:To evaluate the nutritional status and its influencing factors in esophageal cancer patients for home-based care after surgery.Methods:A total of 153 patients with esophageal cancer who underwent surgery between July 2022 and October 2023 in the General Hospital of Eastern Theater Command were enrolled in this study.The nutritional status of the patients at home in 1-month post-surgery was evaluated according to the patient-generated subjective global assessment(PG-SGA),and the possible influencing factors were analyzed.Results:Among the 153 patients,47 were well-nourished and 106 were malnourished,with an overall malnutrition rate of 69.3%.For the malnutritional patients,71 were suspected or moderately malnourished and 35 were severely malnourished.The hemoglobin levels,serum albumin levels,the route for nutrition support delivery,nutrition impact symptoms(NIS),oral nutritional supplements(ONS)and nutritional behavior were independent influencing factors of nutritional status(P<0.05),in which NIS≥2 was a risk factor for malnutrition in the patients.Normal hemoglobin and albumin levels,enteral tube feeding,oral nutritional supplement and achieving standard of nutritional behavior were protective factors for avoiding the presence of malnutrition.Conclusion:The esophageal cancer patients for home-based care after surgery have a high incidence of malnutrition.Many factors,including nutrient delivery route and nutritional behavior,were related to the occurrence of in the patients.Certain measures to the related factors should be taken early for preventing malnutrition in clinical practice.

Objective:To evaluate the risk factors for the formation of parastomal Hernias(PSH)using meta-analysis,and to provide a theoretical basis for the prevention and treatment of PSH.Methods:Case control or Cohort study of PSH risk factors were collected by searching PubMed,CNKI,Wanfang data and other databases.Extract relevant data and perform meta-analysis using RevMan 5.3.Results:The results included a total of 16 studies,with a total sample size of 2411 cases,including 670 in the PSH group and 1741 in the non PSH group.The results showed that advanced age,female gender,BMI≥25,hypertension,COPD/chronic cough,diabetes,and postoperative Hypoproteinemia could increase the risk of PSH(P＜0.05);Smoking,previous ab-dominal surgery history,preoperative radiotherapy/chemotherapy etc.,were not significantly asso-ciated with the occurrence of PSH(P＞0.05).Conclusion:The current evidence shows that ad-vanced age,female gender,BMI≥25,hypertension,COPD/chronic cough,diabetes,postoperative Hypoproteinemia are risk factors for PSH,and extraperitoneal stoma can reduce the occurrence of PSH.

Objective:To analyze the clinical features, treatment, and outcomes of fetal/neonatal atrial flutter (AFL) at the onset of the perinatal period to improve the management of this condition.Methods:This retrospective study analyzed the clinical data, treatment, and follow-up results of fetal/neonatal AFL cases transferred to Shanghai Children's Medical Center from November 2013 to August 2021. Clinical characteristics, cardioversion procedures, and outcomes were summarized. Descriptive method was used for statistical analysis.Results:A total of 21 fetuses/neonates presenting with AFL in the perinatal period were involved in this study, including 17 males and four females. Ten of them were born at full term, and 11 were preterms. All of the patients were delivered by cesarean section at 32 to 41 gestational weeks [ (36.6±1.9) weeks] with a birth weight of 2 130 to 4 450g [ (3 059±528) g]. Increased fetal heart rate was all detected after 32 weeks of gestation, and three of them were diagnosed with AFL by fetal echocardiography before being born. The heart rate remained elevated in all cases after birth. All were diagnosed as AFL based on an electrocardiogram on the day of birth, which showed a 2 to 6 over one ratio of atrioventricular conduction. Among the six cases of cardiac insufficiency and low blood pressure complicated by dyspnea and cyanosis, the symptoms were relieved in four cases after mask oxygenation and two cases after ventilation. Among the 21 cases, one was converted spontaneously to normal sinus rhythm and the other 20 recovered after medication or electrical cardioversion. Seven cases were initially treated by drug conversion with a success rate of 5/7 and hospitalized for 23 d (13-25 d). There was one with cardiac insufficiency before treatment and three newly developed cardiac insufficiency during treatment among the seven cases. Thirteen cases were offered electrical cardioversion initially, and the success rate of cardioversion was 12/13. There were five cases of cardiac insufficiency before treatment, while no new cases of cardiac insufficiency was reported during treatment. The duration of hospitalization was 11 d (9-14 d). Apart from one case, the rest 20 infants were followed up from one month to eight years old, and no recurrence was reported.Conclusions:For fetal/neonatal AFL with the onset during the perinatal period, the symptoms mainly manifest in late pregnancy. Its diagnosis depends on fetal echocardiography before birth or electrocardiogram after birth, and electrical cardioversion is a fast and effective measure. While the prognosis of perinatal-onset AFL is generally good.

To study the material basis of cold and hot properties of traditional Chinese medicines (TCMs) in Lamiaceae and to establish a cold and hot properties identification model, a database of material components of TCMs in Lamiaceae was established. A three-level classification system of material components was used to obtain the material basis of cold and hot properties of the Lamiaceae family by using data mining methods such as frequency analysis, association rule analysis, logistic regression, and feature selection. Several identification models were established to recognize the cold and hot properties. The chi-square test results showed that the material composition ratios of cold and hot properties were significantly different at the first-level, second-level, and third-level classification (P < 0.05), and the differences varied as the levels of substance classification changed. The average coefficients of variation were 42.30%, 79.07%, and 91.51% at the first-level, second-level, and third-level classification levels, respectively. In other words, in terms of the percentage differences in material composition ratio, the first-level was smaller than the second-level, and the second-level was smaller than the third-level. The results of the association rule analysis showed that under the third-level classification, there were many effective association rules, and 27 core groups and 34 specific groups of chemical components were obtained based on these rules. 15 decisive groups were obtained from the feature selection results. Multinomial logistic regression analysis was used to successfully establish a cold and hot properties identification model with an overall accuracy of 89%. The material basis of cold and hot properties of TCMs in Lamiaceae is different and intersect with each other. Twenty-seven groups of chemical components, such as bicyclic diterpenes, are the core groups of cold and hot properties, of which 15 groups are the decisive groups. The cold and hot properties are often characterized by the interaction of multiple classes of substances, and a single class of substances often cannot be used to characterize the properties. The organic combination of multiple classes of substances is the material basis of cold and hot properties.

Circular RNA (circRNA), as a competitive endogenous RNA (ceRNA), plays an importantrole in the regulation of cell differentiation. The purpose of this study was to identify and analyze porcinecircular RNA insulin-like growth factor 1 receptor (circIGF1R), explore its expression patterns, construct a ceRNA regulatory network related to circIGF1R, and explore the regulation of its ectopicexpression on adipogenic differentiation of mouse mesenchymal stem cells (C3H10T1 / 2) effect. Forwardand reverse PCR, Sanger sequencing, RNase R enzyme digestion tests, and qRT-PCR were used toverify that circIGF1R is a circRNA formed by the second exon of insulin-like growth factor 1 receptor(IGF1R). It was expressed in all tissues of pigs, and its expression level increased with age in adiposetissues. miRDB, TargetScan and miRWalk online software were used to predict circIGF1R target genes. RNAhybrid software was used for binding site prediction. DAVID bioinformatics functional analysissoftware was used to perform GO and KEGG enrichment analysis on candidate target genes. Cytoscapesoftware was used to construct the ceRNA network diagram. Based on the gene expression correlation andpredicted target relationship, the GO and KEGG enrichment analysis was drawn and the ceRNA networkwas constructed; the dual luciferase reporter gene test was used, and we found that circIGF1R andFABP4 can bind to ssc (Sus scrofa chromosome) -miR-133a-5p. The circIGF1R overexpression vectorwas successfully constructed and expressed in C3H10T1/ 2 cells. It was found that after overexpression ofcircIGF1R, the expression of key adipogenic regulatory factors CEBPa, CEBPß, FABP4 and PPAR? increased significantly(P<0. 01), and the number of lipid droplets increased significantly. The results ofthis study show that circIGF1R exists in pig adipose tissues, and may positively regulate the adipogenicdifferentiation of C3H10T1/ 2 cells through the ceRNA mechanism, which lays a theoretical foundation forfurther research on circIGF1R regulating the adipogenic differentiation of pig precursor intramuscularadipocytes.

Objective:To study the clinical characteristics of neonatal community-acquired Novel Coronavirus (COVID-19) Omicron variant infection.Methods:From March 30 to May 15, 2022, the epidemiological characteristics, clinical manifestations and outcomes of neonatal cases of community-acquired COVID-19 Omicron variant infection admitted to the isolation ward of our hospital were analyzed.Results:A total of 7 neonates infected with community-acquired COVID-19 Omicron variant were treated, including 3 males and 4 females. All of them were term infants with clear epidemiological exposure history. The infection was originated from caregivers of close contact (parents or babysitters). The main clinical symptoms was upper respiratory tract infection, including fever (6 cases), nasal congestion (6 cases), cough (5 cases), runny nose (2 cases), poor appetite (2 cases) and diarrhea (1 case). On admission, no abnormalities were found in blood routine examination and C-reactive protein (CRP). All but one case had normal serum amyloid A (SAA). No obvious abnormalities were found on chest X-ray. All patients were isolated in single-patient rooms after admission. They received standard symptomatic treatment and regular nucleic acid tests. The first negative nucleic acid results came on median 17 d(8~26 d) after the onset of the disease. The patients were discharged after two consecutive (24 h apart) nucleic acid tests with CT value ≥35 and continued health-monitor at home. On discharge, 5 patients had nasal congestion and 2 of them had cough. During the follow-up 4~6 weeks after discharge, all patients gradually recovered without positive nucleic acid results.Conclusions:All 7 neonates with community-acquired COVID-19 Omicron variant infection have epidemiological exposure history. The main clinical symptoms are long-lasting upper respiratory tract infections. It takes a relatively long time for the nucleic acid to turn negative, however, the overall short-term prognosis is good.
