2.A new target for gene therapy-splicing factor PUF60
Journal of International Oncology 2017;44(7):531-533
Poly(U)-binding-splicing factor 60 KDa (PUF60), a U2-related splicing factor that facilitates 3′splice-site recognition at the early stage of spliceosome assembly.High expression of PUF60 is related to the occurrence of multiple tumors, such as colorectal cancer, ovarian cancer, gastric cancer, liver cancer, et al.PUF60 can regulate the expression of c-myc through the core-human transcription factor Ⅱ basal transcription factor.Anti-PUF60 antibodies are detected in the sera of patients with early-stage and recurrent tumor, and the levels are significantly decreased after the operation.PUF60 can be used as a combined or independent test index for the diagnosis of cancer, which can be a potential new target for gene therapy.

Chinese Journal of Medical Education Research 2011;10(4):451-453
With the development of funcgonal laboratory teaching,the advantages of integrating laboratory resources have been embodied in someway,improving the students'experiment level and their comprehensive analysis ability.But many new problems have also shown up such as unreasonable curriculum,construction of teaching staff.By reinstalling experiment courses,integrating the experiment teaching staff,and exploring the solution to the existing problems,the teaching quality of functional experiment can be promoted
6.Content Determination of Paeoniflorin and Liquoritin in Jiawei Xiaoyao Pills by HPLC
China Pharmacy 2015;(18):2571-2572
OBJECTIVE:To establish the HPLC method for the content determination of paeoniflorin and liquoritin in Jiawei xiaoyao pills. METHODS:It was performed on Hypersil-ODS C18 with the mobile phase of acetonitrile-water(14∶86,V/V)at the flow rate of 1.0 ml/min,the detection wavelength was 230 nm,the column temperature was room temperature and the volume was 10 μl. RESULTS:The linear range was 16.12-80.6 μg/ml for paeoniflorin(r=0.999 6)and 6.08-30.4 μg/ml for liquoritin(r=0.999 8);the RSDs of precision,repeatability and stability tests were all less than 2.0%;the average recovery was respectively 98.51%(RSD=1.94%,n=6)and 98.08%(RSD=1.29%,n=6). CONCLUSIONS:The method is simple,accurate and reliable, and can be used for the content determination of paeoniflorin and liquoritin in Jiawei xiaoyao pills.
7.Preparation of Metoprolol Succinate Sustained-Release Tablet and Its Content Determination
Herald of Medicine 2016;35(8):870-874
Objective To establish a method of preparing metoprolol succinate sustained-release tablet and its content determination. Methods The formulation was optimized through the orthogonal design test by using release rate of the drug as an indicator.The different batches of metoprolol succinate sustained-release tablets were determined by HPLC. Results The tablets could release drug steadily and slowly as designed,which was similar to imported tablets. The linear range of metoprolol succinate was 10-70 μg?mL-1( r=0.999 8) . Conclusion The releasing rate of metoprolol succinate sustained-release tablet prepared in optimum condition can meet the requirement. This preparation technology is simple, the assay method is rapid, sensitive and reproducible.
8.Analysis on diagnostic value of abdominal CT, B ultrasound and magnetic resonance cholangiopancreatography in bile duct stones
China Medical Equipment 2014;(6):76-78
Objective:Comparative analysis of imaging features of abdominal CT, B ultrasound and magnetic resonance cholangiopancreatography in three different methods for detection of extrahepatic bile duct stones. Methods: A random sample of extrahepatic bile duct stones were a sample of 150 cases as the object of study, patients in the endoscopic retrograde cholangiopancreatography after diagnosis, followed by B ultrasound examination, the implementation of CT scanning and MRI imaging in 142 cases, including 78 cases of B ultrasound detection, CT detection, 118 cases underwent MRI examination. Results: The detection results were recorded and compared the 3 imaging methods. Results: The positive rate of B ultrasound 39.4%, the positive rate of CT was 53.8%, MRI positive rate was 86.4%, the positive rate of MRI was significantly higher than that of B ultrasound and CT (x2=59.725, x2=25.595; P<0.01), the detection rate of CT was significantly higher than that of B ultrasound(x2=4.231, P<0.05). Diameter less than 8 mm of extrahepatic bile duct stones with B ultrasound and positive rate of 25%, the positive rate of CT was 33.3%, MRI positive rate was 60%, the positive rate of MRI was significantly higher than that of B ultrasound and CT(x2=7.789, x2=7.789;P<0.01), the detection rate of CT with no significant differences between the B ultrasound. Conclusion:MRI of extrahepatic bile duct stones with B ultrasound and the positive rate of CT is higher, but the clinical needs according to the comprehensive evaluation of individual patients, economic status, symptoms, diagnosis method for selecting suitable.
9.Research progress in notch signaling pathway in breast cancer stem cells
Chinese Journal of Clinical Oncology 2014;(14):938-941
Breast cancer stem cells (BCSC) are group of cells exhibiting self-renewal and multi-directional differentiation potentials. These cells have an important role in the occurrence, development, metastasis, and recurrence of breast cancer. In normal circumstances, the ability of mammary stem cells to differentiate and undergo self-renewal is governed by related signaling pathways. After this mechanism is destroyed, breast stem cells undergo abnormal differentiation, forming breast cancer stem cells that unlimitedly proliferate to develop into breast cancer. As research on BCSC increasingly deepens, regulation of BCSC by notch signaling and its crosstalk with several signaling pathways have drawn a great deal of attention in this field. This paper reports the signaling pathways of breast cancer stem cells and latest studies on this field to better understand the essential role of notch signaling pathway in the occurrence and development of breast cancer and corresponding clinical targeted therapy.
10.Corticosteroids treatment in acute respiratory distress syndrome
Chinese Pediatric Emergency Medicine 2014;21(12):756-759
The presence and persistence of systemic and lung inflammation in children with acute respiratory distress syndrome (ARDS) is the basis for the use of corticosteroids as a therapeutic agent.The trial of ARDS treated with high-dose short-course corticosteroids showed no benefit,even increase motality.At present,the results of randomized controlled trial and meta-analysis suggested that low-dose and replacement-dose methylprednisolone [1-2 mg/(kg· d)] or equivalent types of corticosteroids may decrease the fatality rate,reduce staying days in ICU and the duration of mechanical ventilation.Use of corticosteroids for ARDS in children is still lack of multicenter randomized controlled trial.
