Objective To investigate the value of the ultrasound technique score and the Braden scale in jointly predicting the risk of pressure injuries in patients with severe multiple injuries. Methods According to the inclusion and exclusion criteria, 216 patients who were hospitalized in the Affiliated Central Hospital of Chongqing University from December 2022 to December 2023 were enrolled. The Braden scale and body sur- face ultrasound test results of each patient were collected, and the subject operating characteristic (ROC) curves of the Braden scale, the ultrasound score. and the Braden scale combined with the ultrasound score were counted respectively, and the area under the curve (AUC), sensitivity, specificity, and other predictive indexes were calculated, so as to analyze and compare the clinical value of the prediction of the combined means. Results The incidence of pressure injuries in patients with severe multiple injuries was 24.5%. The AUC of the Braden scale for the risk of pressure injuries in patients with severe multiple injuries was 0.602[95% confidence interval (95% CI) 0.507-0.696, P=0.026]. The sensitivity for diagnosing pressure injuries was 0.868 and the specificity was 0. 184 when using a Braden score of 12 as the cut-off point. The AUC for the ultrasound technique score was 0.898 (95%CI 0.852-0.944, P<0.001). The sensitivity for diagnosing pressure injuries was 0. 962 and the specificity was 0.767 when using an ultrasound score of ≥ 1 as the cut-off point. The AUC for the combination of the Braden score and the ultrasound technique for the risk of developing pressure injuries in patients with severe multiple injuries was 0. 927 (95% CI 0.887 0.958, P < 0.000 1). The sensitivity was 0.975 and the specificity was 0.819 when Braden score 12 and ultrasound score 1 were used as cut-off points. Conclusion In patients with severe multiple injuries, the specificity of the Braden scale for pressure injuries prediction is poor, and the Braden score combined with the ultrasound technology is a more optimized means of assessing pressure injuries risk.

In order to further understand the characteristics of the life history of the Sepia esculenta population in the coastal waters of Jiangsu, the feeding ecology and nutritional niche of the Sepia esculenta were studied by using the carbon and nitrogen stable isotope analysis method based on the samples collected in the coastal ports of Jiangsu. The results showed that there was no significant difference in δ13C and δ15N values between male and female populations of Sepia esculenta; There was a significant correlation between them; the nutritional niche width of male Sepia esculenta （SEAc=0.57‰2） was not significantly different from that of females （SEAc=0.63‰2）, and females were slightly larger than males, and both are highly overlapping （0.62）. Isotopic cluster analysis showed that Sepia esculenta individuals could be divided into three mantle length groups of 75-114 mm, 115-184 mm and 185-204 mm; The niche width of the 114 mm mantle length group was the smallest （SEAc=0.39‰2）; only the niche overlap rate between the 75-114 mm and 115-184 mm mantle length groups was moderate （0.34）, and the niche overlap rate among the other mantle length groups was low. According to the analysis, the change of δ13C value of Sepia esculenta was mainly affected by the isotope baseline value and the migration pattern of Sepia esculenta, while the change of δ15N value was mainly affected by the feeding effect of Sepia esculenta; the height of food resources and habitat utilization between female and male golden squid groups were highly similar; Sepia esculenta at different developmental stages had obvious differences in nutritional niche.

Objective: To explore the effect of myricetin on metabolism and biological rhythm of spontaneous activity in high-fat-diet mice. Methods: Fifteen 6-week-old clean grade C57BL/6 male mice were randomly divided into normal diet group (CON),high-fat diet group (HFD) and high-fat diet + myricetin [(100 mg/ (kg·d)] group (HFD+MYR). From the 10th week of intervention, the spontaneous activity data of the three groups of mice were recorded with the ClockLab biorhythm analysis system. At the end of the 13th week of intervention, the body weight and blood lipid levels of the mice in the three groups were measured. Results: Compared with the CON group, the weight, triglycerides, total cholesterol, and low-density lipoprotein were significantly increased (P＜0.001) in the HFD group, while high-density lipoprotein was significantly decreased (P＜0.001) . The activity phase of the HFD group was significantly delayed (P＜0.001), and the activity mesor and total counts were significantly increased (P＜0.05) . In the HFD+MYR group, there were no significant changes in the body weight and low-density lipoprotein (P＞0.05), while triglycerides and total cholesterol were significantly increased (P＜0.01), and high-density lipoprotein was significantly decreased (P＜0.01), the activity phase was significantly delayed (P＜0.001), and there were no significant changes in the activity mesor and total counts (P＞0.05) compared with CON group. Compared with the HFD group, the body weight, triglycerides, total cholesterol, and low-density lipoprotein were significantly decreased (P＜0.05) in the HFD+MYR group, while high-density lipoprotein was significantly increased (P＜0.05) . The activity phase of the HFD+MYR group was significantly advanced (P＜0.05), and the activity mesor and total counts were significantly reduced (P＜0.05) . Conclusion: Myricetin can improve the metabolic state and relieve the biological rhythm disorder of spontaneous activity in high-fat-fed mice. [ABSTRACT FROM AUTHOR]

Objective: This study aims to compare transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) combined with contrast echocardiography in the evaluation of right-to-left shunt (RLS) of patent foramen ovale (PFO), and propose the optimal diagnostic strategy. Methods: A retrospective study was conducted on 186 patients admitted the cardiovascular department of the First Affiliated Hospital of Nanjing Medical University from February 2020 to February 2022 with cryptogenic stroke (CS), transient ischemic attack (TIA) and migraine who were confirmed to have a patent foramen ovale (PFO) through TEE or cardiac catheterization. Both contrast transthoracic echocardiography (cTTE) and contrast transesophageal echocardiography (cTEE) were performed. In addition, during cTEE, the operator clenched their fist and placed it on the patient's abdomen, applying pressure and then releasing it, while the patient performed a Valsalva maneuver. The number of microbubbles appearing in the left atrium and left ventricle within three cardiac cycles was observed to assess the degree of RLS at the level of the interatrial septum. Results: During rest, cTTE detected 136 cases of RLS, while cTEE detected 140 cases of RLS. During the Valsalva maneuver, cTTE detected 186 cases of RLS, and cTEE also detected 186 cases of RLS, indicating a significant increase in the detection rate of PFO-RLS during the Valsalva maneuver compared to the rest state, regardless of the cTTE or cTEE method. Among the PFO patients with RLS detected, cTTE classified 27 cases as grade I, 31 cases as grade II, and 128 cases as grade III. On the other hand, cTEE classified 80 cases as grade I, 56 cases as grade II, and 50 cases as grade III. Among these cases, 110 patients had a higher RLS degree in cTTE compared to cTEE, with 46 cases being grade III in cTTE and grade II in cTEE, 43 cases being grade III in cTTE and grade I in cTEE, and 21 cases being grade II in cTTE and grade I in cTEE. During the Valsalva maneuver with cTEE, while the operator clenched their fist and applied pressure on the patient's abdomen and then released it, 35 cases were classified as grade I, 46 cases as grade II, and 105 cases as grade III. There were 76 patients with an increase in RLS degree, including 21 patients who upgraded from grade I to grade II, 24 patients who upgraded from grade I to grade III, and 31 patients who upgraded from grade II to grade III. The proportion of patients with moderate to large shunting significantly increased. Conclusion: The RLS level detected by cTTE is higher than that of cTEE. During the cTEE examination, when the patient cooperates with the examiner to press, the degree of RLS detected under Valsalva's action increases. The combination of cTTE and TEE in diagnosing the anatomical structure and morphology of PFO is of great value for the treatment and preoperative evaluation of PFO occlusion. [ABSTRACT FROM AUTHOR]

Non-alcoholic fatty liver disease (NAFLD) has become the most common liver disease worldwide. To date, the US Food and Drug Administration has not approved any treatment for NAFLD. According to the latest diagnosis and treatment guidelines, the primary goal of treatment for NAFLD patients is to lose weight, and dietary intervention is the main means of treatment. The patients can not take into account the nutrition and treatment of daily diet adjustment, unscientific diet and fat reduction can aggravate the progress of fatty liver. The emergence of food for special medical purpose (FSMP) and its successful application in diabetes and other chronic diseases show that it plays an auxiliary role in the treatment of diseases. The development of a FSMP for NAFLD will bring more benefits to the patients. This paper reviewed the development status of FSMP and analyzed the research status of FSMP related to NAFLD,explored the advantages of FSMP compared to conventional dietary interventions, in order to provide theoretical reference for the development and application of NAFLD FSMP in the future.

Chicken disease identification with manual monitoring cannot fully meet the large-scale production in livestock and poultry breeding industry, due to slow speed and chickens prone to cross-infection. The characteristics of chicken feces can be one of the important indicators to reflect the health status of chickens. The different colors and traits of feces are associated with different chicken diseases. In this study, a classification and discrimination model was proposed for the chicken feces using visible-near-infrared spectroscopy. A research foundation was laid for the final realization of early warning of chicken diseases. Four types of typical chicken feces sample were selected, including the normal, red blood streak, green and fodder feces. The spectral data of samples was scanned in the 400-900 nm band. Each type of chicken feces samples was divided into the correction sets (162 samples) and test sets (53 samples) at 3:1, according to the principle of randomness. Multivariate scattering correction, Savitzky-Golay convolution smoothing, and Z-scores normalization were used to preprocess the data. A PLS-DA (partial least squares discriminant analysis) model was then established to select the optimal pretreatment, according to the evaluation index. An improved shuffled frog leaping algorithm was proposed to further optimize the existing partial least squares discriminant analysis model. The calculation rate of the model was effectively improved to obtain a more accurate number of principal factors. The number of iterations was determined to minimize the root mean square error of crossvalidation. The PCA (principal component analysis), CARS (competitive adaptive reweighted sampling), and ISFLA (improved shuffled frog leaping algorithm) were used to reduce the data dimensionality of the processed samples using the preferred pretreatment. Finally, a categorical discriminant model was established after optimization. The results showed that the PLS-DA model established by the SG convolution smoothing-MSC-Z-Scores shared the better performance of normal stool sample data, and for the three types of abnormal samples, the PLS-DA model established by MSC performed better. The accuracies of the test sets were achieved at 74.07%, 91.98%, 96.15%, and 100%, respectively, for four types of feces samples. The optimal data preprocessing was determined using model evaluation. The ISFLA-PLS-DA was used to distinguish between the normal, redblooded feces and green feces, where the accuracies of the test set were 92.27%, 92.59% and 100%, respectively. More importantly, the PCA-PLS-DA should be used for the discrimination in the fodder feces, where the accuracy of the test set was 100%. The dimensionality of the data was reduced by feature extraction to construct the lightweight PLS-DA model. The accuracy of the correction set was significantly improved in each typical stool sample. Specifically, the accuracies of the correction set were significantly improved before optimization, which increased by 7.70, 0.61, and 3.85 percentage point, respectively, of normal, red-blooded feces and green feces. Therefore, rapid, accurate and non-contact detection was achieved in the different types of typical chicken feces using visible-near-infrared spectroscopy detection combined with the characteristic wavelength selection and PLS-DA discrimination. The finding can also provide the strong reference for the intelligent detection technology of chicken disease. [ABSTRACT FROM AUTHOR]

In the distant ancient kingdom of bacteria, high temperatures that suddenly came up mercilessly took the lives of bacteria. In the face of disaster, the King of Bacteria was determined to practice the “thermophilic magic skill” to improve the heat resistance of its cell membrane and protein, and led its group to board the “Noah’s Ark” to achieve the reproduction. Bacteria not only adapted to high temperature but also fell in love with it, becoming “thermophiles”. Through collaboration with human scientists, thermophiles have played an important role in industrial production and other fields, discovering a “new continent” for realizing their own value.
