Aim To evaluate the mechanism of HG251-induced apoptosis in K562/DOX cells.Methods Cell viability was assessed by MTT assay;cell cycle distribution,apoptosis and mitochondrial membrane potential were measured by flow cytometry;the protein expressions of P-gp,caspase-3,caspase-8,caspase-9,p53,Bcl-xL and cytochrome c in the K562/DOX cells were evaluated by Western blot.Results HG251 was able to inhibit cells proliferation,induce apoptosis,lose mitochondrial membrane potential,activate caspase-3,caspase-8,caspase-9,up-regulate p53 protein and down-regulate Bcl-xL protein in a dose-dependent manner but it had no effect on P-gp protein expression.Conclusion HG251 could overcome apoptotic resistance via up-regulating p53 protein and down-regulating Bcl-xL protein.In addition,HG251 also induced K562/DOX cells apoptosis via mitochondrial pathway and membrane death receptor pathway.

Solute Carriers (SLC) superfamily is one of the most important membrane transporter families in the cell membrane (including intracellular membrane) of human,it is involved in some essential physiological functions such as intercellular substance transporting,energy transfer,nutrition and metabolism,signal transduction and so on.Solute Carriers (SLC) superfamily contains 52 subfamilies,with more than 400 members.Studies have shown that abnormal protein expression or functional defects of SLC caused by human genetic mutations are closely related with a variety of serious diseases such as diabetes,hypertension and depression,so the function research of SLC had attracted much attention in recent years.The known three-dimensional structures of SLC transporters help to explain the precise molecular mechanism of substrate binding and transporting,it provides a fine structure basis to study the molecular mechanism of related diseases and structure-based drug discovery.In this review,we summarized the progress on the structure and function of SLC superfamily transporters of late years,try to provide some common rules of SLC superfamily transporters.

To observe the clinical efficacy of combined acupuncture and Tuina in the treatment of enuresis following occult cleft spine and seek quantified indexes for result assessment, 40 subjects were treated by above methods and B-ultrasonically examined before and after treatment to determine the capacity of bladder and the residual urine inside it. The total effective rate was 90%; there was a difference of the capacity of bladder between before and after treatment (P＜0.05); 11 cases suffered from residual urine, and there was also significant difference of residual urine between before and after treatment (P＜0.01). It is revealed that this method can increase the capacity of bladder and diminish residual urine.

In the presence of silver ion, Mn2+ could be electro-oxidized to potassium hypermanganate in phosphoric acid solution, which could effectively react with pyrocatechol in acid solution and luminol in sodium hydroxide solution to produce chemiluminescence. On the basis of this, a novel indirect approach for the detection of Mn2+ was established. The effect of silver ions on the electrochemical oxidation of Mn2+was studied. when 1. 5 ×10-5 mol/L Ag+ and 0. 01 mol/L phosphoric acid solution were used in the process of electrochemical oxidation, the CL intensity could be up to the maximum value after the above solution was electrolyzed for 2 min. The relation of CL intensity and Mn2+concentration in the solutions at different pH and the selectivity were also investigated. when the pyrocatechol was used as luminescent reagent in the acidic medium, the CL intensity was linearly to the Mn2+concentration in the range of 1. 82×10-7-7. 27×10-5 mol/L with excellent selectivity. Common ions had little interferences in the determination of Mn2+. The method was successfully applied to the determination of Mn2+ in surface water and drinking water with satisfactory results.

Transcription factor is one of the key factors in the regulation of gene expression at the transcriptional level. It plays an important role in plant growth, active components biosynthesis and response to environmental change. This paper summarized the structure and classification of bHLH transcription factors and elaborated the research progress of bHLH transcription factors which regulate the active components in plants, such as flavonoids, alkaloids, and terpenoids. In addition, the possibility of increasing the concentration of active substances by bHLH in medicinal plants was assessed. The paper emphasized great significance of model plants and multidisciplinary research fields including modern genomics, transcriptomics, metabolomics and bioinformatics, providing the contribution to improve the discovery and function characterization of bHLH transcription factors. Accelerating the research in the mechanism of bHLH transcription factors on the regulation of active components biosynthesis will promote the development of breeding and variety improvement of Chinese medicinal materials, also ease the pressure of resources exhaustion of traditional Chinese medicine home and abroad.

Objective:To evaluate the safety and efficacy of antiplatelet therapy of ticagrelor on patients suffering from acute ST segment elevation myocardial infarction undergoing primary percutaneous coronary in-tervention. Methods:In the study, 96 patients suffering from acute ST segment elevation myocardial infarction onset within 12 h undergoing primary percutaneous coronary intervention from May to October in 2013 were randomly divided into ticagrelor group (n=48) and clopidogrel group (n=48) by using the method of random number table. Ticagrelor and clopidogrel antiplatelet treatment were used before and after operation. Their baseline data, coronary artery disease characteristics, platelet count, adenosine diphosphate(ADP)-induced platelet inhibition rate by thrombelastograph after 5 days of treatment, the major adverse cardiovascular events of the follow up for 6 months and bleeding complications were observed and compared in the two groups. Re-sults:The differences between the two groups of patients with their baseline data, the features of coronary ar-tery lesions, platelet count before and after 5 days of treatment had no statistical significance (P>0. 05). ADP induced platelet inhibition rate [(80. 2 ± 10. 7)%] after 5 days of treatment in ticagrelor group was sig-nificantly higher than that in clopidogrel group [(75. 3 ± 12. 1)%, P<0. 05]. The two groups of patients were followed up for 6 months, 8 cases of major adverse cardiovascular events occurred in clopidogrel group, 2 ca-ses of major adverse cardiovascular events occurred in ticagrelor group, and there was significant difference between the two groups (P<0. 05). The two groups (7 cases of 48 patients in ticagrelor group vs. 3 cases of 48 patients in clopidogrel group ) had no statistically significant difference in bleeding complications ( P>0. 05). Conclusion: Antiplatelet therapy of ticagrelor on patients suffering from acute ST segment elevation myocardial infarction undergoing emergency PCI has good efficacy and safety.

Objective:To evaluate the clinical feasibility and image quality of three-dimensional breath-hold gradient and spin-echo (3D BH-GRASE) sequence in magnetic resonance cholangiopancreatography (MRCP).Methods:In this prospective study, 59 patients with clinically suspected pancreaticobiliary duct disease performed MRCP with both 3D BH-GRASE and 3D respiration-triggered turbo spin-echo (3D RT-TSE) sequences on 3.0 T scanner in the Affiliated Zhangjiagang Hospital of Soochow University from November 2017 to December 2018. The overall image quality was scored independently by 3 experienced radiologists based on the visibility of different anatomical features of the pancreaticobiliary duct. For comparing the 2 sequences, the statistical difference in scan time was assessed with a paired t test; while subjective scores, signal-to-noise ratios (SNR), contrast ratios (CR) and contrast noise ratios (CNR) were compared with Wilcoxon signed rank test. Results:The scan time of 3D BH-GRASE sequence was 16.4 s while that of 3D RT-TSE was (258.6±42.2) s. Their difference was statistically significant ( t=44.073, P<0.001), with the scan time for 3D BH-GRASE shortened by 94%. The overall quality scores of 3D BH-GRASE images were better than those of 3D RT-TSE ( Z=-6.595, P<0.001). There was no statistical difference ( P>0.05) in the scores regarding the visibility of the upper, middle and lower parts of common bile duct and the first and second branches of left and right hepatic ducts. For visualizing the bottom, body, neck and duct of gallbladder, the 3D BH-GRASE sequence received a higher score than the 3D RT-TSE sequence ( P<0.001). For displaying the proximal, middle and distal segments of main pancreatic duct, the 3D RT-TSE sequence was scored higher than the 3D BH-GRASE sequence ( P<0.05). There was no significant difference of SNR between the two sequences ( Z=0.403, P=0.687), whereas CR and CNR of 3D RT-TSE MRCP were better than those of 3D BH-GRASE MRCP ( Z=6.215, P<0.001 and Z=3.046, P=0.002, respectively). Conclusion:Under the prerequisite of ensuring image quality, a proper use of 3D BH-GRASE sequence can significantly shorten the scan time and thus greatly improve the working efficiency of MRCP examination.

Objective To explore and evaluate the clinical significance of pressure-controlled discography in diagnosis of discogenic low back pain.Methods From July 2008 to October 2009,pressurecontrolled discography under C-arm guidance was taken in 52 patients with suspected discogenic low back pain,including 83 degenerative discs and 52 good discs.Based on the pressure of discography inducing pain,the discs were divided into 4 groups:pressure ≤ 30 psi,30 psi＜pressure ≤50 psi,50 psi＜pressure≤70psi,and pressure＞70 psi.By using SPSS 11.0 statistical software,the correlation of pressure of discography and morphologic representation was analyzed.Results Among 83 degenerative discs,positive discography was detected in 46 discs.During discography,the pressure of positive degenerative discs was (36.5±15.7)psi; the pressure of negative degenerative discs was (50.5±26.2) psi,and the normal discs’ pressure was (98.6±3.7) psi.A significant difference could be found between the mentioned three groups.Among different pressure groups,the positive rate were analyzed by x2 test,and a significant difference was found as well.But no significant difference was found between the group of less than 30 psi and group of 30 to 50 psi.According to Adams’ morphological classification of discography,the pressure of disc varied from 30 to 50 psi in grade Ⅲ,while less than 30 psi in grade Ⅳ.There was a significant difference of discography pressure between discography positive grade Ⅲ and grade Ⅳ.Conclusion The pressure-controlled discography is valuable for clinical diagnosis of discogenic low back pain.The morphological classification of discs could indicate the degree of the disruption of annular fibrosus.
