Abstract
Objective: To explore the application of manual screening collaborated with the Artificial Intelligence TPS-Assisted Cytologic Screening System in urinary exfoliative cytology and its clinical values. Methods: A total of 3 033 urine exfoliated cytology samples were collected at the Henan People's Hospital, Capital Medical University, Beijing, China. Liquid-based thin-layer cytology was prepared. The slides were manually read under the microscope and digitally presented using a scanner. The intelligent identification and analysis were carried out using an artificial intelligence TPS assisted screening system. The Paris Report Classification System of Urinary Exfoliated Cytology 2022 was used as the evaluation standard. Atypical urothelial cells and even higher grade lesions were considered as positive when evaluating the recognition sensitivity, specificity, and diagnostic accuracy of artificial intelligence-assisted screening systems and human-machine collaborative cytologic screening methods in urine exfoliative cytology. Among the collected cases, there were also 1 100 pathological tissue controls. Results: The accuracy, sensitivity and specificity of the AI-assisted cytologic screening system were 77.18%, 90.79% and 69.49%; those of human-machine coordination method were 92.89%, 99.63% and 89.09%, respectively. Compared with the histopathological results, the accuracy, sensitivity and specificity of manual reading were 79.82%, 74.20% and 95.80%, respectively, while those of AI-assisted cytologic screening system were 93.45%, 93.73% and 92.66%, respectively. The accuracy, sensitivity and specificity of human-machine coordination method were 95.36%, 95.21% and 95.80%, respectively. Both cytological and histological controls showed that human-machine coordination review method had higher diagnostic accuracy and sensitivity, and lower false negative rates. Conclusions: The artificial intelligence TPS assisted cytologic screening system has achieved acceptable accuracy in urine exfoliation cytologic screening. The combination of manual screening and artificial intelligence TPS assisted screening system can effectively improve the sensitivity and accuracy of cytologic screening and reduce the risk of misdiagnosis.

Abstract
Objective: To explore the risk factors for syncope in children with severe idiopathic pulmonary arterial hypertension (IPAH). Methods: Forty-four patients (age<18 years) with IPAH admitted to the Department of Pediatric Cardiology, Beijing Anzhen Hospital between May 2011 and October 2021 were retrospectively included. Patients were devided into syncope group and non-syncope group. Clinical manifestation and hemodynamic parameters including echocardiography, blood tests, right heart catheterization and acute pulmonary vascular expansion test were compared between two groups. Comparisons between groups were performed with unpaired Student t test, or Mann-Whitney U test or chi-square test. Logistic regression was used to calculate the odds ratio (OR) for parameters with statistically significant differences between groups and analyze the statistical correlation. Results: Among the 44 patients, 16 were males, the onset age was (7.2±3.9) years. Twenty-four (55%) children presented with 1 to 11 times of episodes of syncope, and 18 cases of whom induced by physical activity. Syncope group had a larger proportion of New York Heart Association (NYHA) heart function class Ⅲ-Ⅳ (67% (16/24) vs. 25% (5/20), χ2=7.59, P=0.006), higher brain natriuretic peptide (BNP) value ((251±39) vs. (61±40) pg/L, t=-2.18, P=0.035), higher pulmonary-to-aorta diameter ratio (1.6±0.4 vs. 1.4±0.2, t=-2.25, P=0.030) and larger pulmonary vascular resistance index ((22±11) vs. (16±7) WU/m2, t=-2.13, P=0.039) compared with non-syncope group. The proportion of patent foramen ovale (4% (1/24) vs. 45% (9/20), χ2=10.36, P=0.001), left ventricular ejection fraction (LVEF) ((68±5)% vs. (72±8)%, t=2.23, P=0.031) and the positive rate of acute pulmonary vascular expansion test (8% (2/24) vs. 35% (7/20), χ2=4.77, P=0.029) of syncope group were significantly lower than those of non-syncope group. Multiple Logistic regression analysis showed that NYHA heart function Ⅲ-Ⅳ (OR=6.787, 95%CI 1.445-31.880), pulmonary vascular resistance index (OR=1.247, 95%CI 1.020-1.525) and BNP (OR=1.036, 95%CI 1.007-1.066) were independent risk factors for syncope. The patent foramen ovale (OR=0.010, 95%CI 0.000-0.586) was a protective factor for syncope. Conclusions: NYHA cardiac function grade, pulmonary vascular resistance index and BNP are independent risk factors for syncope. Patent foramen ovale is a protective factor for syncope. Exercise is the main inducement of syncope in children with IPAH.

Abstract
OBJECTIVE The present meta-analysis aimed to evaluate the efficacy and safety of compression stockings for postthrombotic syndrome (PTS) prevention in patients with deep venous thrombosis (DVT). METHODS Randomized controlled trials (RCTs) regarding the use of compression stockings for prevention of PTS were identified from the Medline, PubMed, and Embase databases as well as the Cochrane library. The resulting manuscripts were analyzed according to the criteria in the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS Six RCTs involving 1465 patients with DVT were included. The meta-analysis indicated no statistical differences between the compression stocking and the control groups in PTS incidence, using either the Villalta scale (odds ratio [OR], 0.63; 95% confidence interval [CI], 0.23-1.74) or the Ginsberg scale (OR, 1.13; 95% CI, 0.72-1.77). Based on the Villalta scale categorization, there were no differences in the incidence of mild-moderate PTS (OR, 0.71; 95% CI, 0.36-1.41) or incidence of severe PTS (OR, 0.68; 95% CI, 0.15-3.11). The difference in the recurrence of venous thromboembolism (OR, 0.89; 95% CI, 0.61-1.30) was also not significant. In the 3 RCTs that reported side effects of compression stockings, they were primarily related to discomfort, including itching, erythema, and rash. CONCLUSION The present meta-analysis has indicated that compression stockings may not prevent PTS, as determined by either the Villalta or the Ginsberg scale, in patients with DVT. However, owing to the limited number of trials, the evidence is not strong enough to draw a reliable conclusion. Further larger, randomized, double-blind, placebo-controlled, multicenter trials are needed.

Abstract
When recovering from general anesthesia, upon removal of the endotracheal tube, patients may experience a high dynamic response in the circulatory system, along with choking and restlessness. This study was designed to study the effect of maintaining an intravenous infusion of remifentanil or propofol on the performance of general anesthesia, including on the cardiovascular response, choking and irritability at the end of general anesthesia. We treated 60 patients with combined inhalation and general anesthesia for lower esophageal cancer resection. When the surgery was complete, narcotic drug treatment ceased, oropharynx and endotracheal suctioning was performed with a simple breathing bag, and the patient was quickly sent to the anesthesia recovery room. In the recovery room, patients were randomly divided into three groups (N = 20): the control group (waiting for extubation), the remifentanil group (target-controlled infusion of remifentanil; the target plasma concentration was 3 ng/ mL) and the propofol group (target-controlled infusion of propofol; the target plasma concentration was 2 μg/mL). The results show that maintaining an intravenous infusion of remifentanil or propofol can reduce the hemodynamic response, choking and irritability observed at the end of palinesthesia after administration of general anesthesia upon removing the endotracheal tube. The patients in the remifentanil group were fully awake when extubating, and remifentanil intervention did not extend the recovery time. Therefore, a maintenance infusion of remifentanil during general anesthesia may be a better choice.

Abstract
The optical properties and the theoretical prediction of color optical shutter with dye-doped polymer network liquid crystal (PNLC) were investigated. The view-angle dependence of reflectance according to the bias conditions showed distinctive characteristics, which could be explained from the effects of dye absorption and path length. It was also shown that the thickness dependence of reflectance was strongly influenced by the light-scattering coefficient. Our experimental results matched up well with the theoretical prediction based on the light scattering of liquid crystals in polymer network and the absorption of dichroic dye. This work indicates potential to improve the optical device using dye-doped liquid crystal-polymer composite.

Abstract
Sepsis-induced glucose dyshomeostasis has been characterized by an initial hyperglycemia followed by a progressive hypoglycemia. It is well known that the liver plays a predominant role on regulating the homeostatic level of blood glucose. Furthermore, recent studies indicate that protein kinase A, activated by c-AMP, contributes to the role of glycagon in glucogenolysis and glyconeogenesis. Kinetic studies of protein kinase were completed. During late sepsis, in order to further understand the pathophysiology of hepatic glucose disturbances during sepsis. This study investigates the role of protein kinase A in the liver regulating carbohydrate metabolism during early sepsis. The work was performed by using an animal septic model, induced by cecal ligation and puncture (CLP) operation. Through the measurement of blood sugar, a two phase change in sugar level was found. That is, blood sugar significantly increased at 4.5 hrs after CLP operation (p < 0.05) and then significantly decreased at 18 hrs (p < 0.01). In the kinetic studies of protein kinase A, the results showed that, during early sepsis, the activities of both type I (eluted at low ionic strength) and type II (eluted at high ionic strength) protein kinase A were unchanged. Moreover, the kinetic parameters, Vmax and S0.5, of protein kinase A showed no significant difference between two groups. As such, it is suggested that hyperglycemia during early sepsis is not connected to the regulation of protein kinase A.

Abstract
The covalent modification of receptor proteins via phosphorylation and dephosphorylation is one of the principal mechanisms controlling carbohydrate metabolism and is known to be regulated by various protein kinases. Recent studies indicated that many hormones may exert their effects on cellular metabolism by regulating intracellular c-AMP levels and by activating a c-AMP dependent protein kinase, i.e., protein kinase A. The metabolic disturbances during sepsis are characterized by an initial hyperglycemia followed by a progressive hypoglycemia and a depletion of hepatic glycogen content. The latter is coupled with a slowdown in glycogenesis, an accelerated glycogenolysis, and a depression in gluconeogenesis in the liver. Since the liver is the major organ that regulates the homeostatic level of blood glucose, it is conceivable that the sepsis-induced glucose dyshomeostasis might be mediated by changes in protein kinase activity and the kinetic characteristics of enzymes. The present experiment was designed to study the correlation between protein kinase A and the pathophysiology of hepatic glucose dyshomeostasis during sepsis. Sepsis was induced in rats by cecal ligation and puncture (CLP). Late sepsis occurred 18 hours after CLP. Protein kinase A was extracted from the rat livers by acid precipitation and ammonium sulfate fractionation, and then partially purified by DEAE-cellulose. The results show that in the late sepsis, type-I protein kinase A (eluted at low ionic strength) activity was significantly decreased by 34-52% (P < 0.01). The kinetic parameters such as Vmax's for ATP, histone, and c-AMP were also significantly decreased from the control values of 6.1 +/- 0.9, 5.4 +/- 0.8, and 5.1 +/- 1.9 nmoles/mg.min. to 3.6 +/- 0.5, 2.8 +/- 0.3, and 2.5 +/- 0.5 nmoles/mg.min., respectively. Analysis using Hill's equation indicates that the S0.5 and n (Hill coefficient) values of the various substrates and activators for type-I protein kinase A remained unchanged. In the case of type-II protein kinase A (eluted at high ionic strength), the Vmax, S0.5, and n values for ATP, histone, and c-AMP were unchanged during late sepsis. The results of the present study indicate that the activities and kinetic characteristics of type I protein kinase A in rat liver are modified during late sepsis. Since protein kinase A is known to regulate glucose metabolism through adrenergic receptor mediation, these findings may have a pathophysiological significance in the understanding of hepatic glucose dyshomeostasis during sepsis.(ABSTRACT TRUNCATED AT 400 WORDS)
