Objective To investigate the expression of p21 and p53 in renal interstitial fibrosis rats and the effect of enalapril on it. Methods Sprague-Dawley rats were randomly divided into 3 groups, shame operation rats group, unilateral urethral obstruction and enalapril treatment group. Histological chan-ges were observed by Masson stain. The expression of p21 mRNA and p53 mRNA was detected by RT-PCR. Results With degree of interstitial fibrosis aggravating, the expression of p21 and p53 increasing,p21 and p53 expression of UUO rats at every time point were positive correlative. Enalapril can inhibit the expression of p21 and p53. Concinsion p21 and p53 expression increased in UUO rats renal cortex and enalapril can significantly inhibit its expression, p21 may participate in the pathogenesis of renal tubule-in-terstitial fibrosis through p53 pathway.

To solve the problem that mostly gait analysis is independent from the treatment, this work proposes a system that integrates the functions of gait training and assessment for foot drop treatment. The system uses a set of sensors to collect gait parameters and designes multi-mode functional electrical stimulators as actuator. Body area network technology is introduced to coordinate the data communication and execution of the sensors and stimulators, synchronize the gait analysis and foot drop treatment. Bluetooth 4.0 is applied to low the power consumption of the system. The system realizes the synchronization of treatment and gait analysis. It is able to acquire and analyze the dynamic parameters of ankle, knee and hip in real-time, and treat patients by guiding functional electrical stimulation delivery to the specific body locations of patients.

OBJECTIVETo explore the relation between genetic polymorphisms of NQO1, GSTT1 and risks of chronic benzene poisoning (BP).

METHODSA case-control study was conducted. 152 BP patients and 152 workers occupationally exposed to benzene without poisoning manifestations were investigated. Polymerase chain reaction (PCR), denaturing high-performance liquid chromatography(DHPLC) and sequencing were used to detect the single nucleotide polymorphisms(SNPs) of the promoter and complete coding-region of NQO1 gene. Multiple PCR was used to detect GSTT1 genotype.

RESULTSIn smoking population, there was 7.73-fold (95% CI: 1.71-34.97, P = 0.010) of risk in BP subjects carrying NQO1c. 609 T/T genotype, compared with those carrying C/C and C/T. genotype. In drinking population, the individuals carrying the 6th extron of NQO1c. 609 T/T homozygote genotype had a 11.00-fold(95% CI: 1.89-63.83, P = 0.005) risk of BP compared to those with NQO1c. 609 C/T and C/C genotypes.

CONCLUSIONThe subjects carrying NQO1c. 609 T/T genotype and together with the habit of smoking or drinking may be more susceptible to BP.

Objective:To explore the clinical value of point-of-care ultrasonography(PoCUS) in the diagnosis of acute pulmonary embolism(PE).Methods:Consecutive 196 patients suspected of acute PE were enrolled in East Branch, the Second Hospital of Hebei Medical University from January 2017 to November 2017. All the patients were categorized into no PE group( n=143) and PE group( n=53) based on CTPA results. PoCUS was performed and considered diagnostic for PE if one or more right ventricular dysfunction (right ventricular dilation, right ventricular free wall hypokinesia, increased tricuspid regurgitation velocity or decreased tricuspid annular plane systolic excursion), deep venous thrombosis(DVT) or subpleural infarcts were detected. Results:With CTPA as the gold standard for diagnosis, the sensitivity (94.34%), Youden index (0.531) and the area under the ROC curve(AUC) (0.765) of the combined diagnosis of PE by transthoracic echocardiography(TTE), lower limb vein compression ultrasonography(CUS) and lung ultrasonography (LUS) were the highest. The specificity (94.41%) and accuracy (81.63%) of LUS in the diagnosis of PE were the highest, and the misdiagnosis rate (5.59%) of LUS the lowest. The sensitivity of the combined triple PoCUS (TTE, CUS, and LUS) diagnosis of PE was higher than TTE and CUS combined diagnosis ( P=0.016), and the sensitivity and specificity were higher than TTE and CUS combined diagnosis as a whole ( P<0.005). Conclusions:The combined triple PoCUS (TTE, CUS, and LUS) has the highest accuracy in the diagnosis of PE, while LUS has a high specificity and a low misdiagnosis rate in the diagnosis of PE. Therefore, it is recommended to apply the combined triple PoCUS in clinical practice.

α-cells, which synthesize glucagon, also support β-cell survival and have the capacity to transdifferentiate into β-cells. However, the role of α-cells in pathological conditions and their putative clinical applications remain elusive due in large part to the lack of mature α-cells. Here, we present a new technique to generate functional α-like cells. α-like cells (iAlpha cells) were generated from mouse fibroblasts by transduction of transcription factors, including Hhex, Foxa3, Gata4, Pdx1 and Pax4, which induce α-cell-specific gene expression and glucagon secretion in response to KCl and Arg stimulation. The cell functions in vivo and in vitro were evaluated. Lineage-specific and functional-related gene expression was tested by realtime PCR, insulin tolerance test (ITT), glucose tolerance test (GTT), Ki67 and glucagon immunohistochemistry analysis were done in iAlpha cells transplanted nude mice. iAlpha cells possess α-cell function in vitro and alter blood glucose levels in vivo. Transplantation of iAlpha cells into nude mice resulted in insulin resistance and increased β-cell proliferation. Taken together, we present a novel strategy to generate functional α-like cells for the purposes of disease modeling and regenerative medicine.

Ramping-up is the magnet current injection procedure which is under the control of resistance, voltage, current lead temperature, magnet pressure, temperature and so on. In this procedure, the factors related to the stability of the magnet such as, magnet temperature, pressure and currents are constantly changing. This procedure is the main step which the magnet-quench occurs in. This study uses the data collected during 7 years and SIMENS MRI ramping-up theory, in order to help engineers understand the key factors to reduce the magnet quench during the ramping up procedure.
