Abstract
OBJECTIVE To investigate the effect of corticosteroid on hospital mortality, hospital length of stay, and time of viral clearance in patients with severe and critical COVID-19. PATIENTS AND METHODS Patients with severe and critical COVID-19 who had been discharged or expired were enrolled in this study. Patients were divided into corticosteroid group and non-corticosteroid group according to the systemic corticosteroid use or not. Clinical data were collected, and hospital mortality, hospital length of stay, time of viral clearance, time of mechanical ventilation, and duration from illness onset to symptom resolution were compared between the two groups. RESULTS A total of 72 inpatients who were diagnosed with severe and critical COVID-19 were enrolled, in which 47 patients were divided into corticosteroid group and 25 were involved as the non-corticosteroid group. Baseline characteristics were generally similar between the two groups. Four (5.6%) patients died during hospitalization, and 68 (94.4%) were discharged. Among survivors, the mean duration time from admission to discharge was 19.5d (SD 7.05 d). The mean time of viral clearance among survivors was 17.5d (SD 7.67 d), with a maximum of 37 d, and a minimum of 5 d. Hospital mortality (4.3% vs. 8.0%), length of hospital stay (18.7d vs. 21.0d), and time of viral clearance (16.1d vs. 19.4d) had no significant difference between two groups (p>0.05). The duration of symptoms suffering was shorter in the corticosteroid group than non-corticosteroid group, with statistically significant difference (p<0.05). CONCLUSIONS Corticosteroid therapy in patients with severe COVID-19 cannot reduce the hospital mortality, and is not associated with delayed viral clearance, but it could relieve the inflammatory storm and improve clinical symptoms in brief. Patients with severe COVID-19 could benefit from low-dose corticosteroid treatment.

BMC Anesthesiol 2020; 20:185. [PMID: 32738878 PMCID: PMC7395215 DOI: 10.1186/s12871-020-01108-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Accepted: 07/26/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Tracheal extubation is commonly performed in the supine position. However, in patients undergoing abdominal surgery, the supine position increases abdominal wall tension, especially during coughing and deep breathing, which may aggravate pain and lead to abdominal wound dehiscence. The semi-Fowler's position may reduce abdominal wall tension, but its safety and comfort in tracheal extubation have not been reported. We aimed to evaluate the safety and comfort of different extubation positions in patients undergoing abdominal surgery. METHODS We enrolled 141 patients with an American Society of Anesthesiologists grade of I-III who underwent abdominal surgery. All patients were anesthetized with propofol, fentanyl, cisatracurium, and sevoflurane. After surgery, all patients were transferred to the post-anesthesia care unit (PACU). Patients were then randomly put into the semi-Fowler's (n = 70) or supine (n = 71) position while 100% oxygen was administered. The endotracheal tube was removed after the patients opened their eyes and regained consciousness. Vital signs, coughing, and pain and comfort scores before and/or after extubation were recorded until the patients left the PACU. RESULTS In comparison with the supine position, the semi-Fowler's position significantly decreased the wound pain scores at all intervals after extubation (3.51 ± 2.50 vs. 4.58 ± 2.26, 2.23 ± 1.68 vs. 3.11 ± 2.00, 1.81 ± 1.32 vs. 2.59 ± 1.88, P = 0.009, 0.005 and 0.005, respectively), reduced severe coughing (8[11.43%] vs. 21[29.58%], P = 0.008) and bucking after extubation (3[4.29%] vs. 18[25.35%], P < 0.001), and improved the comfort scores 5 min after extubation (6.11 ± 2.30 vs. 5.17 ± 1.78, P = 0.007) and when leaving from post-anesthesia care unit (7.17 ± 2.27 vs. 6.44 ± 1.79, P = 0.034). The incidences of vomiting, emergence agitation, and respiratory complications were of no significant difference. CONCLUSION Tracheal extubation in the semi-Fowler's position is associated with less coughing, sputum suction, and pain, and more comfort, without specific adverse effects when compared to the conventional supine position.

Abstract
Line mixing effects have been calculated in various parallel and perpendicular bands of self-broadened PH3 lines and compared with recent experimental data. The theoretical approach is an extension to symmetric tops with high inversion barrier of the formalism previously developed for NH3 [Q. Ma and C. Boulet, J. Chem. Phys. 144, 224303 (2016)]. The model takes into account the non-diagonality of the scattering operator within the line space as well as, in a correct way, the double degeneracy of the j, k levels when k ≠ 0. Transitions between such levels should be considered as doublets whose components may be coupled by the line mixing process. It has been shown that, at low pressure, the inversion of the experimental data will strongly depend on the splitting between the two components of a doublet. When it is significant, one can measure independently both the width of one component and the intra-doublet coupling matrix element. Otherwise, one can only measure the sum of these two elements. Comparisons with measurements show that the present formalism leads to accurate predictions of the experimental line shapes.

Abstract
A Fast Charge eXchange Recombination Spectroscopy (CXRS) diagnostic with eight radial channels has been implemented on a HuanLiu-2A (HL-2A) tokamak with a time resolution of up to 10 kHz monitoring helium II spectra or 1 kHz monitoring carbon VI spectra. The crucial aspects of the fast CXRS are to improve the spectral intensity and the acquisition frequency. The spectral intensity has been greatly enhanced by customized fiber bundles. The main boost in optimizing the acquisition frequency is achieved by binning more pixel rows of the charge coupled device (CCD) representing one radial channel and by reducing the effective image area of the CCD. Consequently, the sawtooth oscillations of ion temperature and rotation velocity are continuously observed for the first time in the HL-2A tokamak.

Abstract
We use measurements from NASA's Van Allen Probes to calculate the decay time constants for electrons over a wide range of energies (30 keV to 4 MeV) and L values ( L = 1.3-6.0) in the Earth's radiation belts. Using an automated routine to identify flux decay events, we construct a large database of lifetimes for near-equatorially mirroring electrons over a 5-year interval. We provide the first accurate estimates of the long decay timescales in the inner zone ( ∼ 100 days), which are highly resolved in energy and free from proton contamination. In the slot region and outer zone, we compare our lifetime calculations with prior empirical estimates and find good quantitative agreement (lifetimes ∼ 1-20 days). The comparisons suggest that some prior estimates may overestimate electron lifetimes between L ≈ 2.5-4.5 due to instrumental effects and/or background contamination. Previously reported two-stage decays are explicitly demonstrated to be a consequence of using integral fluxes.

Abstract
We compute quasilinear diffusion rates due to pitch angle scattering by various mechanisms in the Earth's electron radiation belts. The calculated theoretical lifetimes are compared with observed decay rates, and we find excellent qualitative agreement between the two. The overall structure of the observed lifetime profiles as a function of energy and L is largely due to plasmaspheric hiss and Coulomb scattering. The results also reveal a local minimum in lifetimes in the inner zone at lower energy ( ∼ 50 keV), attributed to enhanced scattering via ground-based very low frequency transmitters, and a reduction in lifetimes at higher L and energy ( > 1 MeV), attributed to enhanced electromagnetic ion cyclotron wave scattering. In addition, we find significant quantitative disagreement at L < 3 . 5 , where the theoretical lifetimes are typically a factor of ∼ 10 larger than the observed, pointing to an additional loss process that is missing from current models. We discuss potential factors that could contribute to this disagreement.

Abstract
Objective: To investigate the characteristics of frailty in the elderly male patients with chronic kidney disease (CKD) and the effects of renal function on the incidence of frailty. Methods: A total of 105 non-dialysis CKD patients aged ≥65 years who were admitted to the Chinese PLA General Hospital between October 1, 2018 and January 30, 2019 were included in this study. Their clinical data and laboratory indicators were collected. Frailty was defined according to Fried frailty criteria. According to the frailty scores, the participants were categorized as non-frail (n=37), intermediately frail (n=37) and frail (n=31). The association of frailty and the level of estimated glomerular filtration rate (eGFR) in the patients was analyzed using the model of multivariate Logistic regression. Results: Among the 105 patients, the mean age was 74 (68, 77) years old. The incidence of frail and intermediate frail was 35.2% (37/105) and 29.5% (31/105), respectively. Multivariate logistic analysis showed statistically significant associations of frailty with age (OR=1.14, 95%CI:1.08-1.20, P<0.001), body mass index (OR=0.87, 95%CI:0.79-0.95, P=0.001) and the level of eGFR (OR=0.98, 95%CI:0.96-0.99, P=0.003) in those patients. The incidence of frail in patients with eGFR<45 ml·min(-1)·(1.73 m(2))(-1) and 45-59 ml·min(-1)·(1.73 m(2))(-1) was 1.02 (OR=2.02, 95%CI: 1.06~3.87) and 0.84 (OR=1.84, 95%CI: 1.05-3.22) times higher than that of eGFR≥60 ml·min(-1)·(1.73 m(2))(-1), respectively. Conclusion: The incidence of frailty in the elderly patients with CKD is affected by many factors, such as age, body mass index and renal function, and increases with decreased renal function.

Abstract
Objective: To identify the therapeutic efficacy of lithium chloride (LiCl) on phosphatase and tensin homolog deleted on chromosome ten (PTEN)-deficient tumors. Methods: First, the Catalogue of Somatic Mutations in Cancer for mutation spectrum of human endometrial carcinoma samples was analyzed. Second, the relationship between PTEN abundance and LiCl inhibition of endometrial cancer cell lines using Pten(+/+) and Pten(-/-) mouse embryonic fibroblast (MEF) lines was investigated. Moreover, potential alterations of mammalian target of rapamycin (mTOR) signaling pathway after treatment with LiCl were checked.Last,LiCl's efficacy on PTEN null tumors was studied. Results: PTEN was mutated in 39% of endometrial carcinomas. LiCl preferentially inhibited the proliferation of PTEN-deficient endometrial carcinoma cells and MEFs. Furthermore, LiCl blocked PTEN-deficient tumor development. Mechanistically, LiCl down-regulated mTOR signaling. Conclusions: PTEN is the most frequently mutated gene in endometrial carcinoma.By targeting mTOR signaling pathway,LiCl is a promising regimen for the treatment of tumors with PTEN deficiency.

Abstract
This article unveiled that ethylene biosynthesis and signaling play a critical role in heat stress response of tomato plants under elevated CO2. Plant responses to elevated CO2 and heat stress are tightly regulated by an intricate network of phytohormones. Plants accumulate ethylene (ET), the smallest hormone, in response to heat stress; however, the role of ET and its signaling in elevated CO2-induced heat stress response remains largely unknown. In this study, we found that transcript levels of multiple genes relating to ET synthesis, signaling, and heat shock proteins (HSPs) were induced by elevated CO2 (800 μmol mol-1) compared to ambient CO2 (400 μmol mol-1) in tomato leaves under controlled temperature conditions (25 °C). Elevated CO2-induced responses to heat stress (42 °C) were closely associated with increased ET production and HSP70 expression at both transcript and protein levels. Pretreatment with an antagonist of ET, 1-methylcyclopropene that inhibits ET-dependent responses, abolished elevated CO2-induced stress response without affecting the ET production rate. In addition, silencing of ethylene response factor 1 (ERF1) compromised elevated CO2-induced responses to heat stress, which was associated with the concomitant reduction in the transcript of heat shock factor A2, HSP70 and HSP90, indicating that ERF1 is required for elevated CO2-induced responses to heat. All these results provide convincing evidence on the importance of ET biosynthesis and signaling in elevated CO2-induced heat stress response in tomato plants. Thus, the study advances our understanding of the mechanisms of elevated CO2-induced stress response and may potentially be useful for breeding heat-tolerant tomatoes in the era of climate change.

Abstract
Abstract Objective To explore the distribution of genetic structure of Y-SNP and Y-STR genetic markers in different ethnic groups and its application in forensic science. Methods SNaPshot minisequencing was used to detect the polymorphisms of 12 Y-SNP loci in 439 males from 6 ethnic groups, including Guangxi Han, Guangxi Jing, Guangxi Miao, Guangxi Yao, Guangxi Zhuang and Guangxi Dong. DNATyperTM Y26 kit was used to multiplex-amplify 26 Y-STR loci. The PCR products were analyzed by 3130xl genetic analyzer. The network analysis of Y-STR haplotype under the same Y-SNP haplogroup was analyzed by Network 5.0 software. Results Six haplogroups defined by 12 Y-SNP loci were detected in 6 ethnic groups, and 362 haplotypes were detected in 26 Y-STR loci. The haplotype diversity was 0.996 6. In the C haplogroup, the samples from Guangxi Yao, Guangxi Zhuang and Guangxi Dong were clustered on different branches; in the O1 haplogroup, those from Guangxi Zhuang, Guangxi Miao and Guangxi Jing were relatively independent and clustered separately; in the O2 haplogroup, some samples from Guangxi Miao and Guangxi Yao were gathered in a cluster. Conclusion Based on the Y-STR network analysis of samples with identical haplogroup of Y-SNP, some ethnic groups can be preliminarily distinguished, which could be used to infer male suspects' ethnic group through detecting their genetic markers left in the crime scene.

Abstract
Objective: To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. Methods: 530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients. Results: A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05). Conclusions: Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It's important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.

Abstract
Climate changes such as heat waves often affect plant growth and pose a growing threat to natural and agricultural ecosystems. Elevated atmospheric CO2 can mitigate the negative effects of heat stress, but the underlying mechanisms remain largely unclear. We examined the interactive effects of elevated CO2 (eCO2 ) and temperature on the generation of the hydrogen peroxide (H2 O2 ) and stomatal movement characteristics associated with heat tolerance in tomato seedlings grown under two CO2 concentrations (400 and 800 µmol mol-1 ) and two temperatures (25 and 42°C). eCO2 ameliorated the negative effects of heat stress, which was accompanied by greater amounts of RESPIRATORY BURST OXIDASE 1 (RBOH1) transcripts, apoplastic H2 O2 accumulation and decreased stomatal aperture. Silencing RBOH1 and SLOW-TYPE ANION CHANNEL, impeded eCO2 -induced stomatal closure and compromised the eCO2 -enhanced water use efficiency as well as the heat tolerance. Our findings suggest that RBOH1-dependent H2 O2 accumulation was involved in the eCO2 -induced stomatal closure, which participate in maintaining balance between water retention and heat loss under eCO2 concentrations. This phenomenon may be a contributor to eCO2 -induced heat tolerance in tomato, which will be critical for understanding how plants respond to both future climate extremes and changes in CO2 .

The expressions of miR-18a and miR-21 in normal esophageal epithelial cell HET-1A, esophageal cancer cell lines including ECA109, KYSE150 and TE1 were also detected. Chemiluminescence immunoassay was used to quantitatively detect the concentrations of carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC), CYRFA21-1 and TPA (tissue polypeptide antigen) in peripheral blood serum from esophageal cancer patients and healthy controls. Meanwhile, the diagnostic effects of miR-18a and miR-21 on esophageal cancer were compared with those of tumor markers in serum. Results: The expression levels of miR-18a and miR-21 in esophageal cancer cells ECA109, KYSE150 and TE1 were 1.64±0.17, 1.62±0.19, 1.46±0.12 and 20.52±1.48, 6.73±0.73, 1.43±0.19, respectively, higher than those in normal esophageal epithelial cells (both P<0.01). The expressions of miR-18a and miR-21 in esophageal cancer tissues were 32.48±28.62 and 8.67±11.98, respectively, significantly higher than those in adjacent tissues (all P<0.001). The expression levels of miR-18a and miR-21 in peripheral blood of patients with esophageal cancer were 12.66±11.92 and 9.15±8.14, respectively, significantly higher than those in the normal control group (both P<0.001). The receiver operating characteristic (ROC) curve analysis showed that the area under the curve of miR-18a and miR-21 for diagnosis of esophageal cancer were 0.948 and 0.913 5, respectively. Compared with traditional esophageal tumor markers, the expressions of miR-18a and miR-21 were more sensitive in the diagnosis of esophageal cancer. The sensitivity and accuracy of the expressions of miR-18a and miR-21 combined with traditional esophageal tumor markers in diagnosis of esophageal cancer can be further improved to 97.8% and 68.4%, respectively. Conclusion: Our study reveals that the expressions of miR-18a and miR-21 play important roles in the diagnosis of esophageal cancer and may be potentially novel biomarkers.

Abstract
The three central phenomena of cuprate (copper oxide) superconductors are linked by a common doping level p*-at which the enigmatic pseudogap phase ends and the resistivity exhibits an anomalous linear dependence on temperature, and around which the superconducting phase forms a dome-shaped area in the phase diagram1. However, the fundamental nature of p* remains unclear, in particular regarding whether it marks a true quantum phase transition. Here we measure the specific heat C of the cuprates Eu-LSCO and Nd-LSCO at low temperature in magnetic fields large enough to suppress superconductivity, over a wide doping range2 that includes p*. As a function of doping, we find that Cel/T is strongly peaked at p* (where Cel is the electronic contribution to C) and exhibits a log(1/T) dependence as temperature T tends to zero. These are the classic thermodynamic signatures of a quantum critical point3-5, as observed in heavy-fermion6 and iron-based7 superconductors at the point where their antiferromagnetic phase comes to an end. We conclude that the pseudogap phase of cuprates ends at a quantum critical point, the associated fluctuations of which are probably involved in d-wave pairing and the anomalous scattering of charge carriers.

Abstract
Objective: To explore the psychological status and related factors in patients with precancerous of esophageal and gastric cardia in Linzhou of Henan. Methods: Clinical psycho-rating scale of Social Support Rating Scale (SSRS), Self-Rating Anxiety Scale (SAS, score ≥50 points with symptoms of anxiety) and Self-Rating Depression Scale (SDS, score ≥53 points with the symptoms of depression) were applied to survey life events and psychological status of subjects who aged 40-69 years old and participated in"The Early diagnosis and Early Treatment"program in Linzhou cancer hospital from July 2015 to Jan 2016. Patients with lower intraepithelial neoplasia or high-grade intraepithelial neoplasia were selected as precancerous lesions (n=118), and patients with normal grade were selected as healthy controls (n=210). Compare the differences of the scores between the two groups, and the logistic regression model was used to analyze the related factors of precancerous lesions and psychological status of the study subjects. Results: Precancerous lesions included esophageal (72 cases), gastric cardia (40 cases), esophageal and cardia dual source (6 cases); Precancerous lesions and healthy controls aged (57.17±7.71) and (53.12±7.99) years old, the difference was statistically significant (P<0.001). The anxiety and depression scale showed that the scores of SAS and SDS scores in the precancerous lesions were (37.18±10.01), (40.44±8.37) points, and (34.02±6.63), (38.49±8.73) points in control group, the difference was statistically significant (P=0.002, 0.032). While the social support total score (38.26±5.26), and subjective support score (24.08±3.83) and objective support score (7.50±1.89) in control group were all higher than those of precancerous group (36.80±6.18, 23.01±3.93, 6.93±1.57), and the difference were statistically significant (P=0.024, 0.016, 0.004). In addition, the Logistic analysis showed that subjects with low objective social support, subjective social support and anxiety symptoms were more likely to develop precancerous lesions, and the OR were 0.81, 0.72 and 1.05, respectively (P=0.028, 0.005, 0.009). Conclusion: Social support, anxiety and depression status may be related to the occurrence and development of esophageal and gastric cardia precancerous lesions.

Abstract
Objective: To analyze whether heat-shock protein 90 (HSP90) be involved in a permanently abnormal activated JAK/STAT signaling in ATL cells in vitro. Methods: The effect of 17-AAG on proliferation of ATL cell lines HUT-102 was assessed using CCK8 at different time points. Cell apoptosis was measured by flow cytometry. The specific proteins HSP90, STAT5, p-STAT5 and JAK3 were detected by Western blotting. Results: Overexpression of HSP90 in HUT-102 cell lines was disclosed (P<0.05) , and constitutive activation of JAK3/STAT5 signaling was observed in HTLV-1-infected T-cell lines but not in normal PBMCs; Treatment of ATL cell lines with 17-AAG led to reduced cell proliferation, but there was no significant change in terms of cell proliferation when the concentration of 17-AAG between 2 000-8 000 nmol/L (P>0.05) . 17-AAG induced cell apoptosis in different time-points and concentrations. 17-AAG don't affect the expression of JAK3 gene. Conclusion: This study indicated that JAK3 as HSP90 client protein was aberrantly activated in HTLV-1-infected T-cell lines, leading to constitutive activation of p-STAT5 in JAK/STAT signal pathway, which demonstrated that HSP90-inhibitors 17-AAG inhibited the growth of HTLV-1-infected T-cell lines by reducing cell proliferation and inducing cell apoptosis.

Abstract
Objective: To observe the analgesic and sedative effect and safety of application of dexmedetomidine combined with remifentanil in dressing change of conscious patients with non-intubation in burn intensive care unit. Methods: Forty patients conforming to the study criteria hospitalized in our burn intensive care unit from April 2015 to April 2017 were selected. Prospective, randomized, and double-blind method was used for the design. Patients were divided into dexmedetomidine group and dexmedetomidine+ remifentanil group according to the random number table, with 20 cases in each group. Patients in the two groups were respectively given corresponding drugs during dressing change. The frequency and time of dressing change, Verbal Rating Scale (VRS) score of patients during dressing change (at drug administration for 25 minutes) and after dressing change (25 min after dressing change), Ramsay Sedation Score (RSS) during dressing change, satisfaction level for anesthesia of the patients and physicians after dressing change, dosage of remifentanil, and various adverse effects during and after dressing change were recorded. The heart rate, mean arterial blood pressure (MAP), respiratory rate, and pulse oxygen saturation (SpO2) before drug administration and at 10, 15, and 25 minutes after drug administration were also recorded. Data were processed with analysis of variance for repeated measurement, t test, chi-square test, and Fisher's exact probability test. Results: (1) Totally 38 patients completed the trial. There were no statistically significant differences between patients in two groups in gender, American Association of Anesthesiologist Grading, age, weight, and total burn area (χ2=0.230, 0.146, t=0.224, 0.351, 0.367, P>0.05). (2) The frequency of dressing change of patients in two groups were both 48 times. The time of dressing change and VRS scores during dressing change of patients in two groups were similar (t=0.821, 1.522, P>0.05). The VRS score of patients in dexmedetomidine+ remifentanil group after dressing change was (3.1±0.4) points, obviously lower than (3.8±0.8) points in remifentanil group (t=2.213, P<0.05). The RSS, satisfaction level scores for anesthesia of the patients and physicians after dressing change in dexmedetomidine+ remifentanil group were (3.13±0.32), (3.44±0.41), and (3.13±0.25) points, respectively, obviously better than (1.82±0.24), (2.71±0.23), (2.53±0.41) points in remifentanil group (t=2.226, 2.684, 7.702, P<0.01). The dosage of remifentanil of patients in dexmedetomidine+ remifentanil group was (282±19) μg, obviously less than (340±31) μg in remifentanil group (t=9.896, P<0.01). There were no statistically significant differences between patients in two groups in rates of respiratory inhibition and hypotension (χ2=0.211, 0.154, P>0.05). Compared with those in remifentanil group, the rates of nausea, vomiting, and other gastrointestinal symptoms of patients in dexmedetomidine+ remifentanil group were obviously reduced (P<0.05), but the rate of bradycardia was obviously increased (χ2=6.008, P<0.05). (3) There were no statistically significant differences between patients in two groups in heart rate, MAP, respiratory frequency, and SpO2 before drug administration (t=0.444, 0.892, 1.059, 1.039, P>0.05). The heart rates of patients in dexmedetomidine+ remifentanil group at 10, 15, and 25 minutes after drug administration were (83±11), (78±10), and (82±14) times per minute, respectively, significantly lower than (95±10), (87±12), and (89±12) times per minute in remifentanil group (t=5.592, 3.992, 2.630, P<0.05 or P<0.01). The MAP of patients in dexmedetomidine+ remifentanil group at 15 and 25 minutes after drug administration were (69.4±3.1) and (73.8±2.2) mmHg (1 mmHg=0.133 kPa), respectively, significantly lower than (75.4±3.0) and (78.1±3.5) mmHg in remifentanil group (t=9.181, 7.206, P<0.01). There were no statistically significant differences between patients in two groups in respiratory frequency at each time point after drug administration (t=1.489, 1.862, 1.963, P>0.05). The SpO2 of patients in dexmedetomidine+ remifentanil group at 15 minutes after drug administration was 0.972±0.018, obviously lower than 0.979±0.015 in remifentanil group (t=2.070, P<0.05). Conclusions: Application of remifentanil with small dosage has effective analgesia for conscious burn patients with non-intubation during dressing changes, however, adverse effects such as nausea and vomiting are likely to occur. Remifentanil combined with dexmedetomidine not only guarantee the analgesic effect, but also reduce the dosage of analgesics, improve the sedative effect and satisfaction of the patients for anesthesia, and reduce various adverse effects. However, it will increase the incidence of bradycardia and has some inhibition effect on circulation at the same time.

Abstract
Chitosan/montmorillonite intercalated composite (CTS/MMT) was used as an effective adsorbent for removal of reactive dyes, i.e. Reactive Black 5 (RB5), Reactive Red 136 (RR136), Reactive Yellow 145 (RY145) and Reactive Blue 222 (RB222). Taguchi method attached grey relational analysis was applied to determine the optimal adsorption conditions, including pH, initial concentration of dye, temperature, adsorbent dosage and contact time, for achieving simultaneous maximization of removal percentage and adsorption capacity. The percentage contribution of each adsorption condition was determined in the analysis of variance and showed that the most effective parameter in removal of RB5, RY145 and RB222 is the dye solution pH, whereas the initial concentration was the determining factor for optimum efficiency for the dye RR136. Under respective optimal condition, the removal percentages and adsorption capacity of four reactive dyes onto CTS/MMT were both found in the following order: RR136 > RY145 > RB5 > RB222. The maximum removal percentages of 78.8 and 49.5%, and the adsorption capacity of 315.20 and 123.75 mg/g were obtained for RR136 and RB222, respectively. The adsorption behaviors showed that the adsorption kinetics and isotherms were in best agreement with Avrami fractionary order model and the Toth isotherm, respectively.

Abstract
Objective: To observe the effect of Yiqi Wenyang Decoction on the infiltration and activation of NK cells in nasal mucosa of mouse model with allergic rhinitis (AR), and to explore the potential mechanism for effective intervention of AR with Yiqi Wenyang Decoction. Methods: Fourty-eight mice were randomly divided into blank group, model group, low, medium and high dose of Yiqi Wenyang Decoction group and Cetirizine group, with 8 rats in each group. After modeling of AR, the model group was filled with 0.9% sodium chloride solution. Yiqi Wenyang Decoction groups of each dose were given different concentrations of Yiqi Wenyang Decoction water extract, while the Cetirizine group was given aqueous solution of Cetirizine. The behavior, morphological changes of nasal mucosa and infiltration of NK cells in nasal mucosa were observed. The levels of IL-4 and INF-γ in nasal lavage fluid were measured. Besides, the drug safety was observed by acute toxicity test. Results: In the respect of behavioral scoring, middle and high dose of Yiqi Wenyang Decoction group were superior to the model group (number of sneezing: q value was 7.189, 8.748, respectively; number of scratching nose: q value was 12.074, 14.560, respectively; all P<0.05). In middle and high dose of Yiqi Wenyang Decoction group, the infiltration of NK cells and nasal lavage fluid IL-4 levels were lower than those in model group (IOD: q value was 10.073, 12.322, respectively; IOD/Area: q value was 10.954, 14.073, respectively; IL-4: q value was 4.705, 6.801, respectively; all P<0.05). There was no significant difference in nasal lavage fluid of INF-γ among each group (Fv=1.166, P>0.05). In acute toxicity test, no obvious poisoning symptoms and death occurred in mice. Conclusion: Yiqi Wenyang Decoction can control the nasal symptom, reduce the local NK cell infiltration of nasal mucosa and inhibit the expression of the 2-type cytokines released by NK cells, which may be related with the potential mechanism of effective intervention of AR with Yiqi Wenyang Decoction.

Abstract
Line coupling and line mixing effects have been calculated for several self-broadened NH3 lines in parallel bands involving an excited v 2 mode. It is well known that once the v 2 mode is excited, the inversion splitting quickly increases as this quantum number increases. In the present study, we have shown that the v 2 dependence of the inversion splitting plays a dominant role in the calculated line-shape parameters. For the v 2 band with a 36 cm-1 splitting, the intra-doublet couplings practically disappear and for the 2v 2 and 2v 2 - v 2 bands with much higher splitting values, they are completely absent. With respect to the inter-doublet coupling, it becomes the most efficient coupling mechanism for the v 2 band, but it is also completely absent for bands with higher v 2 quantum numbers. Because line mixing is caused by line coupling, the above conclusions on line coupling are also applicable for line mixing. Concerning the check of our calculated line mixing effects, while the present formalism has well explained the line mixing signatures observed in the v 1 band, there are large discrepancies between the measured Rosenkranz mixing parameters and our calculated results for the v 2 and 2v 2 bands. In order to clarify these discrepancies, we propose to make some new measurements. In addition, we have calculated self-broadened half-widths in the v 2 and 2v 2 bands and made comparisons with several measurements and with the values listed in HITRAN 2012. In general, the agreements with measurements are very good. In contrast, the agreement with HITRAN 2012 is poor, indicating that the empirical formula used to predict the HITRAN 2012 data has to be updated.

Abstract
Objective: To investigate the overall incidence and age distribution of upper digestive tract cancer in Cixian county, and to provide a reliable basis of prevention and treatment for upper gastrointestinal cancer. Methods: Collected annual incidence rate among 2003-2012 from Cixian cancer registry and abstracted all incidence rate of upper digestive tract cancer. The age-standardized incidence rate by Chinese standard population (ASR China) was calculated using the national population composition of 2000. The age-standardized incidence rate by world standard population (ASR world) was calculated using the world population composition of 1964 of Segi's. The annual average change (APC) was used to estimate the growth rate of the last two years in comparision with the first two years, which was calculated by Joinpoint regression model. The data was divided into two sections (from 2003 to 2007, and from 2008 to 2012), and the rate difference of different age group was calculated. Results: The crude incidence rate of the digestive tract cancer from 2003 to 2012 was 165.36/100 000 (10 309/6 234 346), which dropped from 170.75/10 100 000 (1 029/602 638) of 2003 to 146.02/100 000 of 2012 (936/640 991).The PC and APC of the crude incidence rate of upper gastrointestinal cancer were-12.96%, and-1.54% (95%CI:-3.22%-0.07%), respectively. The PC and APC of ASR China were-10.83%, and-1.30% (95%CI: 2.54%-0.03%), respectively. The PC and APC of ASR world were-9.82%, and-1.13% (95%CI:-2.20%--0.03%), respectively. The incidence of upper gastrointestinal cancer decreased. The incidence rate of 2003-2007 and 2008-2012 were 171.55/100 000 (5 239/3 048 593), and 159.41/10 000 (5 070/3 180 514), respectively and the rate difference was-12.15/100 000. The decrease of rate difference of 70 to 74 years old was the most (-340.32/100 000) and the increase of rate difference over the age of 85 was the most (447.21/100 000). Conclusion: From 2003 to 2012, the crude incidence of upper digestive tract cancer in Cixian showed a decreasing trend, and the 70-74 years old age group shows the most obvious decline.

Abstract
Objective: To observe the effects of arnebia root oil on wound healing of rats with full-thickness skin defect, and to explore the related mechanism. Methods: Eighty SD rats were divided into arnebia root oil group and control group according to the random number table, with 40 rats in each group, then full-thickness skin wounds with area of 3 cm×3 cm were inflicted on the back of each rat. Wounds of rats in arnebia root oil group and control group were treated with sterile medical gauze and bandage package infiltrated with arnebia root oil gauze or Vaseline gauze, respectively, with dressing change of once every two days. On post injury day (PID) 3, 7, 14, and 21, 10 rats in each group were sacrificed respectively for general observation and calculation of wound healing rate. The tissue samples of unhealed wound were collected for observation of histomorphological change with HE staining, observation of expressions of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) with immunohistochemical staining, and determination of mRNA expressions of VEGF and bFGF with real time fluorescent quantitive reverse transcription polymerase chain reaction. Data were processed with analysis of variance of factorial design, t test, and Bonferroni correction. Results: (1) On PID 3, there were a few secretions in wounds of rats in the two groups. On PID 7, there were fewer secretions and more granulation tissue in wounds of rats in arnebia root oil group, while there were more secretions and less granulation tissue in wounds of rats in control group. On PID 14, most of the wounds of rats in arnebia root oil group were healed and there was much red granulation tissue in unhealed wounds, while part of wounds of rats in control group was healed and there were a few secretions and less granulation tissue in unhealed wounds. On PID 21, wounds of rats in arnebia root oil group were basically healed, while there were still some unhealed wounds of rats in control group. (2) On PID 3 and 7, the wound healing rates of rats in arnebia root oil group were (39±5)% and (46±4)% respectively, which were close to (34±3)% and (44±4)% of rats in control group (with t values respectively 0.807 and 0.481, P values above 0.05). On PID 14 and 21, the wound healing rates of rats in arnebia root oil group were (76±4)% and (90±3)% respectively, which were significantly higher than (60±6)% and (73±5)% of rats in control group (with t values respectively 2.308 and 3.072, P<0.05 or P<0.01). (3) On PID 3, 7, and 14, granulation tissue, fibroblasts, and nascent capillaries in unhealed wound tissue of rats in the two groups both gradually increased, and more ranulation tissue, fibroblasts, and nascent capillaries were seen in unhealed wound tissue of rats in arnebia root oil group. On PID 21, granulation tissue, fibroblasts, and nascent capillaries in unhealed wound tissue of rats in the two groups both gradually decreased. (4) On PID 3, 7, and 14, the numbers of VEGF positive cells and bFGF positive cells in unhealed wound tissue of rats in the two groups both gradually increased; there were more VEGF positive cells and bFGF positive cells in unhealed wound tissue of rats in arnebia root oil group than those in control group. On PID 21, positive expressions of VEGF and bFGF both decreased in unhealed wound tissue of rats in the two groups. (5) On PID 3, 7, and 14, mRNA expressions of VEGF in unhealed wound tissue of rats in arnebia root oil group were higher than those of control group (with t values from 2.967 to 4.173, P values below 0.01). On PID 21, mRNA expression of VEGF in unhealed wound tissue of rats in arnebia root oil group was lower than that of control group (t=-4.786, P<0.001). From PID 3 to 21, mRNA expressions of bFGF in unhealed wound tissue of rats in arnebia root oil group were higher than those of control group (with t values from 2.326 to 4.702, P<0.05 or P<0.01). Conclusions: Arnebia root oil can promote wound healing of rats with full-thickness skin defect, which may relate to increasing expressions of VEGF and bFGF.

Abstract
Line shape parameters including the half-widths and the off-diagonal elements of the relaxation matrix have been calculated for self-broadened NH3 lines in the perpendicular ν4 band. As in the pure rotational and the parallel ν1 bands, the small inversion splitting in this band causes a complete failure of the isolated line approximation. As a result, one has to use formalisms not relying on this approximation. However, due to differences between parallel and perpendicular bands of NH3, the applicability of the formalism used in our previous studies of the ν1 band and other parallel bands must be carefully verified. We have found that, as long as potential models only contain components with K1 = K2 = 0, whose matrix elements require the selection rule Δk = 0, the formalism is applicable for the ν4 band with some minor adjustments. Based on both theoretical considerations and results from numerical calculations, the non-diagonality of the relaxation matrices in all the PP, RP, PQ, RQ, PR, and RR branches is discussed. Theoretically calculated self-broadened half-widths are compared with measurements and the values listed in HITRAN 2012. With respect to line coupling effects, we have compared our calculated intra-doublet off-diagonal elements of the relaxation matrix with reliable measurements carried out in the PP branch where the spectral environment is favorable. The agreement is rather good since our results do well reproduce the observed k and j dependences of these elements, thus validating our formalism.

Abstract
Objective: To investigate the possibility of heart rate as an optimum index for evaluating physical labor intensity. Methods: From September to October, 2015, a total of 111 male young adults were selected as study subjects. A cycle ergometer was used for exercise at different intensities (20, 40, 60, 80, 100, 120, 140, 160, and 180 W) , and the exercise at each intensity lasted for 6 minutes. The subjects wore the K4b2 portable cardiopulmonary function testing instrument for the real-time monitoring of heart rate (HR) , pulmonary ventilation volume (Ve) , oxygen consumption (VO(2)) , and energy metabolic rate (E) . The origin software was used for correlation and regression analyses of HR, Ve, VO(2), and E collected at different intensities to establish Ve-HR, VO(2)-HR, and E-HR regression equations. Results: At different intensities, HR was positively correlated with Ve, VO(2), and E (r=0.8985, 0.8733, and 0.8973, all P<0.01) . There was a significant difference in the R(2) value of Ve-HR, VO(2)-HR, and E-HR regression equations (R(2)=0.8070, 0.7625, and 0.8049, all P <0.01) . The validation results showed that there was no significant difference between the calculated values and the measured ones (P>0.05) . Conclusion: HR can replace Ve, VO(2), and E and be used as an optimum index for evaluating physical labor intensity.

Abstract
Objective: To explore the clinical value of bendopnea in chronic heart failure patients with reduced ejection fraction (HFrEF). Methods: According to the existence of bendopnea or not, a total of 192 consecutive chronic heart failure patients with HFrEF admitted to our department from January 2014 to January 2016 were divided into the bendopnea group and non-bendopnea group. Subgroup analysis was performed in the subgroups with various bendopnea symptoms appearance time (0-10 s, 11-20 s and 21-30 s). The relationship between bendopnea and left ventricular ejection fraction (LVEF), 6-minute walking distance (6-MWD), NT-proBNP and NYHA classification were analyzed. Results: Bendopnea was confirmed in 74 out of 192 (38.54%) cases with HFrEF, and the average time of symptoms appearance was (8.62±2.29) s. LVEF and 6-MWD values were significantly lower in the bendopnea group than those in the non-bendopnea group (both P<0.05). The NT-proBNP level and the prevalence of patients with NYHA grade Ⅳ were significantly higher in the bendopnea group than those in the non-bendopnea group (both P<0.05). There were significant difference on LVEF, 6-MWD, NT-proBNP and patients with NYHA grade Ⅳ in bendopnea patients with various bendopnea symptoms appearance time (all P<0.05) and shorter bendopnea symptoms appearance time was related to severe symptoms and signs of chronic heart failure. Conclusion: The incidence rate of bendopnea is high in patients with HFrEF, and which is related closely to the cardiac function and shorter bendopnea symptoms appearance time is related to severe symptoms and signs of chronic heart failure in HFrEF patients.

Abstract
BACKGROUND Although tea consumption has been reported to have various health benefits in humans, its association with health-related quality of life (HRQOL) has not been investigated directly. We aimed to examine the relationship between tea consumption and HRQOL among older Chinese adults. METHODS We analyzed community-based cross-sectional data of 5,557 older Chinese individuals aged 60 years or older who participated in the Weitang Geriatric Diseases study. Information on tea consumption and HRQOL assessed by the European Quality of Life-5 dimensions (EQ-5D) were collected by questionnaires. We estimated the relationship of tea consumption and the EQ-5D index score using linear regression models and the association between tea consumption and self-reported EQ-5D health problems using logistic regression models. RESULTS The EQ-5D index score was higher for habitual tea drinkers than their counterparts. In multivariate linear analyses controlling for socio-demographic conditions, health conditions, and lifestyle habits, the differences in ED-5D index score between individuals with and without tea drinking habits was 0.012 (95% confidence interval, 0.006-0.017). In multivariate logistic analyses, habitual tea drinking was inversely associated with reporting of problems in EQ-5D dimensions mobility (odds ration [OR], 0.44; 95% CI: 0.23-0.84); pain/discomfort (OR, 0.74; 95% CI: 0.61-0.90); and anxiety/depression (OR, 0.60; 95% CI: 0.38-0.97). These associations were more evident for black or oolong tea than green tea. CONCLUSION Habitual tea consumption was associated with better HRQOL in older adults.

Abstract
Objectives The renal activity index for lupus (RAIL) score was developed in children with lupus nephritis as a weighted sum of six urine biomarkers (UBMs) (neutrophil gelatinase-associated lipocalin, monocyte chemotactic protein 1, ceruloplasmin, adiponectin, hemopexin and kidney injury molecule 1) measured in a random urine sample. We aimed at prospectively validating the RAIL in adults with lupus nephritis. Methods Urine from 79 adults was collected at the time of kidney biopsy to assay the RAIL UBMs. Using receiver operating characteristic curve analysis, we evaluated the accuracy of the RAIL to discriminate high lupus nephritis activity status (National Institutes of Health activity index (NIH-AI) score >10), from low/moderate lupus nephritis activity status (NIH-AI score ≤10). Results In this mixed racial cohort, high lupus nephritis activity was present in 15 patients (19%), and 71% had proliferative lupus nephritis. Use of the identical RAIL algorithm developed in children resulted in only fair prediction of lupus nephritis activity status of adults (area under the receiver operating characteristic curve (AUC) 0.62). Alternative weightings of the six RAIL UBMs as suggested by logistic regression yielded excellent accuracy to predict lupus nephritis activity status (AUC 0.88). Accuracy of the model did not improve with adjustment of the UBMs for urine creatinine or albumin, and was little influenced by concurrent kidney damage. Conclusions The RAIL UBMs provide excellent prediction of lupus nephritis activity in adults. Age adaption of the RAIL is warranted to optimize its discriminative validity to predict high lupus nephritis activity status non-invasively.

Abstract
OBJECTIVE Bone marrow stromal cells (BMSCs) have great potential for cell-based transplantation therapy in treating neurological disease. However, the best combination of various trophic factors to produce full neural differentiation of BMSCs was still unclear. In our study, we aimed to investigate the neural differentiation capacity of rat BMSCs induced by growth factors including hepatocyte growth factor (HGF) and glial cell-derived neurotrophic factor (GDNF). MATERIALS AND METHODS Cell counting kit-8 (CCK-8) assay, BrdU cell proliferation assay and flow cytometry were implemented to evaluate whether GDNF and HGF had positive effects on the proliferation of BMSCs. Moreover, the expression of neural specific markers in BMSCs was identified using immunofluorescence and quantitative real-time polymerase chain reaction (RT-PCR) at various time points (1, 7, 14 and 21-day post-induction). RESULTS CCK-8 and BrdU proliferation analyses demonstrated that only HGF treatment had positive effects on the proliferation of BMSCs on the day 14 and 21 after incubation. RT-PCR and immunofluorescence analyses showed that GDNF and HGF elevated the expression of nestin and NCAM, and the combined application of GDNF and HGF has the most significant effect on day 7 after induction. However, at the day of 14 and 21 post-induction, the expression level of nestin and NCAM in GDNF-treatment group was significantly higher than the other three groups. CONCLUSIONS HGF, not GDNF plays a positive role in BMSCs proliferation, whereas GDNF and HGF are capable of promoting BMSCs to differentiate into neuron-like cells.

Abstract
Objective: To compare the success rates of wire-guided biliary cannulation (WGC) and conventional cannulation (CC) and their effect on the outcome of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). Methods: All randomized controlled trials (RCTs) were collected by searching CNKI, WanFang Data, CBM, PubMed, Embase and Cochrane Library.The assessment of methodological quality and data extraction of the included studies were performed independently by two reviewers. Meta-analysis was conducted with RevMan 5.2 software. Results: Ten RCTs, with a total of 3 262 patients enrolled, were retrieved.Meta-analysis demonstrated that WGC had a higher success rate(RR=1.04, 95%CI 1.01-1.06, P<0.01)and a lower risk of PEP after cannulation (RR=0.54, 95%CI 0.41-0.71, P<0.01). The main reason for the lower risk of PEP was due to lower proportion of mild PEP patients after WGC(RR=0.52, 95%CI 0.36-0.73, P<0.01), while the incidence of modest and severe PEP was comparable in the two groups(modest group: RR=0.84, 95%CI 0.43-1.64, P=0.61; severe group: RR=0.53, 95%CI 0.22-1.31, P=0.17). Conclusion: WGC may increase the success rate of cannulation and reduce the incidence of PEP because of less complications of mild PEP.

Abstract
PR1, an HLA-A2-restricted peptide derived from both proteinase 3 and neutrophil elastase, is recognized on myeloid leukemia cells by cytotoxic T lymphocytes (CTL) that preferentially kill leukemia and contribute to cytogenetic remission. To evaluate safety, immunogenicity and clinical activity of PR1 vaccination, a phase I/II trial was conducted. Sixty-six HLA-A2+ patients with acute myeloid leukemia (AML: 42), chronic myeloid leukemia (CML: 13) or myelodysplastic syndrome (MDS: 11) received three to six PR1 peptide vaccinations, administered subcutaneously every 3 weeks at dose levels of 0.25, 0.5 or 1.0 mg. Patients were randomized to the 3 dose levels after establishing the safety of the highest dose level. Primary endpoints were safety and immune response, assessed by doubling of PR1/HLA-A2 tetramer-specific CTL, and the secondary endpoint was clinical response. Immune responses were noted in 35 of 66 (53%) patients. Of the 53 evaluable patients with active disease, 12 (24%) had objective clinical responses (complete: 8, partial: 1 and hematological improvement: 3). PR1-specific immune response was seen in 9 of 25 clinical responders vs. 3 of 28 clinical non-responders (p=0.03). In conclusion, PR1 peptide vaccine induces specific immunity that correlates with clinical responses, including molecular remission, in AML, CML and MDS patients.

Abstract
The purpose of this study was to determine the in vitro effects of different anticoagulant drugs on fibrinopeptide A (FPA) generation inhibition and to identify whether there is any correlation between FPA generation, Hemochron ACT, global clotting as says, and chromogenic assays. Unfractionated heparin is a conventionally used anticoagulant. New anticoagulant drugs such as low molecular weight heparins (LMWHs), pentasaccharide, and antithrombin drugs are now approved for various indications. Anti-Xa drugs are in various phases of clinical development. The influence of different anticoagulant agents has been studied on fibrinopeptide A generation, Hemochron celite ACT, global clotting assays, and chromogenic anti-Xa and anti-Ila assays. Different LMWHs (Clivarin, Dalteparin, Enoxaparin, and Tinzaparin), anti-Xa agents (Pentasaccharide, DX-9065a and unfractionated heparin), and anti-Ila agents (PEG-Hirudin, Hirudin, Efegatran and Argatroban) were studied. The blood from healthy volunteers (n=4) was drawn for each drug. Imuclone FPA enzyme-linked immunosorbent kit assay, Hemochron celite ACT assay, global clotting assays (PT, APTT, Heptest-HI, thrombin time), and Loyola chromogenic anti-Xa and anti-Ila assays were studied. Pentasaccharide demonstrated minimal effects on the whole blood clotting time such as ACT and on inhibition of FPA generation (IC50 > 25 /g/mL). DX-9065a exhibited a significant prolongation of ACT and marked inhibition of FPA generation (IC50 = 4.12 Ag/mL). Unfractionated heparin showed a marked inhibition of FPA generation (IC,, = 5.16 Aog/mL). Pentasaccharide, DX-9065a and UFH showed a marked correlation between ACT and inhibition of FPA generation. LMWHs demonstrated concentrationdependent inhibition of FPA generation. LMWHs studied showed good correlation between FPA generation inhibition and ACT test. Similar correlation was seen between FPA generation inhibition and the APTT, anti Xa (heptest-HI assay) and anti-IIa activity. Anti-IIa drugs demonstrated concentration-dependent inhibition of FPA generation. Their FPA generation inhibition potency is correlated with the ACT assay. A strong correlation between Hemochron ACT and FPA generation inhibition was observed. Based on this significant correlation, the FPA generation inhibition can be predicted by point-of-care ACT assay.
