42 Background: For esophageal cancer, no viable non-invasive detection technologies are available today. In earlier investigations, Cancer Differentiation Analysis (CDA) Technology which measures information relating to both protein fragments and cellular signals in blood samples in a single test has showed a significant advantage in esophageal cancer diagnosis. Methods: Blood samples from 105 individuals in EDTA tubes were collected from Shanghai Changhai Hospital, China, between July and December 2014, CDA and endoscopy tests were carried out on all samples before clinically diagnosed. A performance predication model of CDA and endoscopy test results was built using pROC package in R Language for the data of Area Under the Curve (AUC) and CDA threshold values. Further analysis was carried out based on the CDA threshold values. Results: Out of the 105 individuals, samples from 6 individuals diagnosed as esophageal benign diseases were selected as control group. 99 samples from individuals diagnosed as esophageal cancer, of which 3 and 82 cases were adenocarcinoma and squamous carcinoma, 2, 26, 33, 31 and 7 cases were classified as stage 0,I,II, III, IV, respectively. Details of AUC results of endoscopy, and CDA plus endoscopy for each group were given in Table 1 below. Conclusions: Even though the sensitivity of the endoscopy is usually high due to its pathological examination, this investigation showed that CDA technology could further enhance the diagnosis sensitivity of endoscope, especially for early stage of esophageal cancer, and it (CDA) can be an effective complementary tool to clinical diagnosis and operation determination while obtaining the pathological information via endoscopy. In conclusion, CDA technology is of great value in esophageal diagnosis and therapeutic decision-making. [Table: see text]

e23131 Background: Cancer Differentiation Analysis liquid biopsy (CDA) has been investigated as a viable clinical utility in NSCLC diagnosis, as well as a new candidate for part of an overall post-CT scan clinical diagnostic and treatment decision tool kit. It has been also evaluated in NSCLC diagnosis, combined with imaging technologies. Methods: This was a retrospective investigation in which 160 individuals were recruited at Changhai Hospital of Shanghai from July to Dec. in 2014. CDA and CT scan tests were performed on all samples before final confirmation by biopsy. For CDA tests, peripheral blood was drawn in EDTA tubes before operation. A performance predication model of CDA and CT scan test results was built using pROC package in R Language for the data of Area Under the Curve (AUC) and CDA threshold values. Further analysis was carried out based on the CDA threshold values. Results: Out of the 160 individuals, 40 were diagnosed as benign lung diseases selected as control group, 120 were confirmed as NSCLC by pathology. CDA and CT test data along with epidemiological information were collected and complied. Details of other statistical results were given in the Table below. Conclusions: CDA liquid biopsy is a novel, multi-level, multi-parameter based disease diagnosis technology with improvements in multiple areas including but not limited to higher sensitivity and specificity, ability to diagnose cancer early, no side effects, and covering a wide range of cancer sites. Results showed that AUC values of CDA were higher than those of CT scan for all NSCLC stage groups. CDA plus CT scan combination has the highest average AUC value for all stages. CDA test can provide more accurate and reliable diagnostic information and data for oncologists in making crucial clinical decisions. It is expected that CDA liquid biopsy technology will play an important and critical role in NSCLC diagnosis. [Table: see text]

Background The diagnosis of acute mesenteric ischemia is variable. Early diagnosis is important for reducing the mortality and morbidity rates. Aim This experimental study aims to investigate the diagnostic utility of D-dimer and neopterin as a marker for the early stage of acute mesenteric ischemia caused by occlusion of superior mesenteric artery. Methods The levels of D-dimer and neopterin were measured using an animal acute mesenteric ischemia model in 21 male rabbits. Superior mesenteric artery occlusion (Group 1, n = 14) and control (Group 2, n = 7) groups were identified. Blood samples at different times are collected from each rabbits. Blood samples from superior mesenteric artery occlusion group were taken 30 min after anesthesia but before laparotomy, 1, 2, and 3 h after superior mesenteric artery ligation. Blood samples from control group were taken 1 h before, 1 and 3 h after anesthesia and laparotomy. The D-dimer and neopterin levels of each blood sample were measured. Results The probability of acute mesenteric ischemia was found to be 36 times higher when the D-dimer level was over 0.125 ng/L, whereas the probability was 19.2 times higher when the neopterin level was over 1.25 nmol/L. Conclusions In this experimental study, the combined elevation of two significant markers, D-dimer and neopterin, may be helpful for the early diagnosis of acute mesenteric ischemia.

Background: Esophageal cancer was hardly diagnosed in early stage, and more potential biomarkers should be found. Methods: 252 patients and normal controls which recruited in Renmin Hospital of Wuhan University, were divided into esophageal carcinoma group (105 cases), disease control group (75 cases) and the control group of healthy people (72 cases). Moreover, TISIDB and GEPIA databases were used to investigate the different expression of EC and normal tissues, and explore the roles of C1q in tumor-immune system interactions in EC. Results: The concentration of serum C1q in EC group is 196.8(180~219.4) mg/L, which is higher than the level of DC [178.10(153.70~200.85) mg/L]and HC [183.00(167.75~201.00) mg/L] (P<0.05). A higher expression level of C1q was observed in Ⅲ and Ⅳ grades [214(192~237.3) mg/ml] than grades Ⅰ and Ⅱ [180.95(172.03~193.85) mg/L] (P<0.05). C1q was positively correlated with eosinophils, active CD8 T cells, myeloid derived suppressor cells, natural killer cells, monocytes and macrophages (r = 0.373; r = 0.659; r = 0.846; r = 0.760; r = 0.499; r = 0.757; P<0.05). Conclusion: The concentrations of C1q increased in EC and related to the severity of EC, which had potential value of diagnosis of EC. There were correlations in C1q and tumor-infiltrating lymphocytes.

Digeda-4 decoction is a traditional Mongolian medicine; its effects on cytochrome (CYP) enzymes are still unclear. CYP450 isoenzymes are the main drug metabolic enzymes, and their activities may be induced or inhibited by certain drugs, which lead to drug interactions in clinical use. Effects of Digeda-4 decoction on the activities of CYP450 subtype enzymes CYP1A2, CYP2C9, CYP2E1, CYP2C19, and CYP3A4 in rats were studied by cocktail method, and the pharmacokinetic parameters of five specific probe drugs (theophylline, tolbutamide, chlorzoxazone, omeprazole, and midazolam) were calculated by DAS software; changes of parameters can be used to evaluate the effects of Digeda-4 decoction on enzyme activities. The experimental rats were divided into three groups: control group, Digeda group, and positive group. Rats in Digeda group were given Digeda-4 decoction through continuous gavage for 14 days. After fasting for 12 hours, the mixed probes drug solution was injected into the tail vein; the blood samples were collected through the orbital vein at different time points. The concentrations of probe drugs in rat plasma were measured by HPLC. Compared with the control group, the half-life time (t1/2) of the pharmacokinetic parameters of theophylline, tolbutamide, omeprazole, and midazolam was prolonged, the area under the curve (AUC) increased, and the plasma clearance (CL) decreased in the Digeda group. Continuous gavage administration for 14 days may inhibit the activities of CYP450 subtype enzymes CYP1A2, CYP2C9, CYP2C19, and CYP3A4 of rats. Herb-drug interaction should be noted between Digeda-4 decoction and the drugs metabolized by CYP1A2, CYP2C9, CYP2C19, and CYP3A4.

Objective: To investigate the gustatory function in patients with semantic dementia (SD). Methods: Detection and recognition thresholds of the 4 basic tastes (sweet, salty, sour, and bitter), taste discrimination, and taste identification were evaluated in 18 patients with SD, 18 patients with Alzheimer disease (AD), and 22 healthy controls. Results: Total detection and recognition threshold values were significantly higher in the SD and AD groups than in the control group. Patients with early-stage SD (Clinical Dementia Rating Scale score 0.5) exhibited significantly higher detection and recognition thresholds relative to controls, while increases in recognition threshold were only noted in patients with AD. Patients with SD exhibited significantly higher thresholds for the detection of sweet and salty tastes and the recognition of salty, sour, and bitter tastes, while patients with AD exhibited significantly higher thresholds only for the recognition of salty and sour tastes. Taste discrimination was preserved, whereas taste identification was disturbed, in both the SD and AD groups. Conclusions: Gustatory dysfunction at both the sensory and semantic levels may be among the early symptoms of SD. Although patients with SD had difficulty detecting sweet tastes, they more easily recognized these tastes than others, which may explain their strong preference for sweets.

Currently about 30% to 50% of all dairy cows are affected by a metabolic or infectious disease during the transition period. A key factor for preventive actions is the ability to precisely predict metabolic diseases at an early stage. We report the longitudinal metabolic profile of non-esterified fatty acids, beta-hydroxybutyrate (BHB), total bilirubin, and aspartate aminotransferase in hyperketonemic dairy cows. Aiming for a novel measurement regime to improve metabolic health in dairy cows, we evaluated prognostic classifiers for hyperketonemia. In the observational longitudinal study, 99 healthy adult primiparous and multiparous Simmental dairy cows were included. Every cow was monitored weekly for 14 consecutive weeks, beginning two weeks prior to the expected day of parturition until peak lactation. Cows with serum concentrations of BHB > 0.8 mmol/L were considered hyperketonemic. Biomarker profiles were fitted by the maximum likelihood method using a mixed effects natural cubic spline model. In the hyperketonemic group, the BHB profile remained significantly higher than that of the control group until the end of the study period. As a prognostic classifier, the cut-off level of 0.54 mmol/L BHB measured on the 10th day post partum had the highest area under the curve. These results provide new longitudinal insights into the metabolic biomarker progression of dairy cows and enable an early onset diagnosis of hyperketonemia.

Liver disease or liver cancer is the sixth most common cancer and the third leading cause of cancer mortality in the world. Hepatitis viral infection, food additives, alcohol, fungal toxins (aflatoxins), toxic industrial chemicals, air and water pollutants are the major risk factors of liver cancer. Moreover, due to high tolerance of liver, HCC is seldom detected at an early stage and once detected treatment faces a poor prognosis in most cases.Fumaria indica possesses hepatoprotective activity as evidenced by the significant and dose dependent restoring the activities of entire liver cancer marker enzymes, diminution in tumor incidence, decrease in lipid peroxidation (LPO) and increase in the level of antioxidant enzymes (GSH, CAT, SOD, GPx and GST) through scavenging of free radicals, or by enhancing the activity of antioxidant, which then detoxify free radicals. These factors protect cells from ROS damage in NDEA and CCl4-induced hepatocarcinogenesis. Histopathological observations of liver tissues too correlated with the biochemical observations. Thus, present investigation suggested that the Fumaria indica would exert a chemoprotective effect by reversing the oxidant-antioxidant imbalance during hepatocarcinogenesis induced by NDEA and CCl4. Besides Fumaria indicais very much effective in preventing NDEA-induced multistage hepatocarcinogenesis possibly through antioxidant and antigenotoxic nature, which was confirmed by various liver injury and biochemical tumour markers enzymes. The hepatoprotective activity of a Fumaria indicaof 50 % ethanolic extract was studied using rats. The animals received a single intraperitoneal injection of N-nitrosodiethylamine 200mg/kg body wt followed by subcutaneous injection of CCl4 in a dose of 3 ml/kg body wt. Fumaria indica extract dose dependently and significantly the increase in serum hepatic enzyme levels after NDEAand CCl4 treatment compared to the toxin control group. The results of this study confirmed the antioxidant and hepatoprotective activity of the Fumaria indicaextract against carbon tetrachlorideand N-nitrosodiethylamine induced hepatotoxicity in rats. In addition to this, studies on molecular aspect of hepatoprotective therapy will give mechanistic information in hepatoprotective therapy and also critical balance should be there between the animal model and clinical research. The hepatoprotective properties of Fumaria indicashould provide useful information in the possible application in hepatic liver disease.

Fat Soluble Vitamins

Vitamins are essential for the health of all living organisms. Vitamins E, A, D and K are known as fat-soluble vitamins, and deprivation of vitamin E causes various disorders, especially in the reproduction and cardiovascular systems and in muscle functions. Vitamin A, on the other hand, has roles in various biological functions – like eyesight – and the growth, reproduction and differentiation of epithelial cells. Vitamin A deficiency leads to the keratinization of the epithelium, and disorders related to the metaplasies of the genital and genitourinary systems. Conversely, vitamin D is defined as a pro-hormone and is responsible for Cahomeostasis, and thus indirectly affects the bone metabolism, bone structure, and cellular and neural functions of Ca. White muscle disease (WMD) can occur in newborn lambs, but is more commonly seen in lambs of up to 3 months of age. In this study, 30 lambs of 3 to 50-days-old from different flocks diagnosed with White Muscle Disease (WMD) were selected as research material, while the control group consisted of 8 healthy lambs. With the aim of clarifying the cause of WMD, serum fat-soluble vitamins, retinol, α-tocopherol and vitamin D3 levels were determined in 16 lambs. Gluteal and heart musclet issue samples also were taken from 30 lambs with WMD. The vitamin levels of the samples were analysed by HPLC. The levels of serum α-tocopherol, retinols, and vitamin D3 were foundto be low in the diseased animals, but only retinol (p<0.001) and α-tocopherol (p<0.0011) level differences were statistically relevant. Macroscopically, Zenker’s necrosis was determined in the heart muscles of 17 lambs, and in the gluteal and chest muscles of 6 lambs. 7 lambs displayed necrosis in both their heart and in gluteal muscles. The samples were analyzed microscopically to reach similar findings: swollen homogeneous pink muscles, pycnotic nuclei, and hyperaemic and haemorrhagic blood vessels in gluteal, chest and heart muscles. Hyaline degeneration and Zenker's necrosis, dystrophic regions in necrotic areas, cc was detected as a severe disease in lambs at an early stage of life with advanced degeneration in different muscle tissues. Deficiency of fat-soluble vitamins was also detected in the sick animals. Control group lambs had higher levels of α tocopherol and retinol (p<0.001) compared to the sick lambs. .
