1.Effects of Cisplatin on Proliferation and Invasion of Colorectal Cancer Cells
Tianjin Medical Journal 2014;(7):638-640
Objective To investigate the effect of cisplatin on proliferation and invasion of colorectal cancer cell line SW480. Methods SW480 cells were used as the research object, and untreated SW480 cells were used as the control group. Different concentrations of cisplatin was given at different times to intervene. The MTT, Transwell chamber and phos-phate determination methods were used to detect proliferation, invasion and Na+-K+-ATPase activity expression level in SW480 cells. Results The physiological concentration of cisplatin (70 μmol/L) inhibited the proliferation of SW480 cells at 48 h. There was no significant difference in the inhibition rate at 48 h compared with 72 h and 96 h. Treatment with 70 μmol/L cisplatin for 48 h reduced the number of cells through Matrigel membrane matrix. The Na+-K+-ATPase activity was significantly increased in 35, 70 and 140 μmol/L cells after treatment with 17.5, 35, 70 and 140 μmol/L of cisplatin in SW480 cells for 48 h, and Na+-K+-ATPase reached the highest level at 70 μmol/L of cisplatin. Conclusion The decreased activity of Na+-K+-ATPase may lead to the attenuation in proliferation and invasion of colorectal cancer cells, which may be associated with cisplatin resistance in colorectal cancer cell SW480.

4.Research progress of long non-coding RNAs in colorectal cancer
Journal of Medical Postgraduates 2016;29(5):556-560
Long non-coding RNAs ( LncRNAs) are a class of RNA transcripts greater than 200 nt in length without the func-tion of protein encoding.LncRNAs, which consist of a great variety of categories and structures, regulate the associated gene expression on multiple levels, including chromatin modification, transcriptional and post-transcriptional regulation, and epigenetic modification. Moreover, LncRNAs are widely involved in the physiological and pathological processes.Recently, a large number of studies have found that the abnormal expression of LncRNAs is closely related to the occurrence, development, invasion and metastasis of tumor, and plays an essential role in pathogensis of colorectal cancer.In this paper, the function of LncRNAs in colorectal cancer is reviewed, which provides a theoretical evidence for its use in the diagnosis and treatment of colorectal cancer in clinical study.

Methods: A sample of 550 college students was selected with the method of stratified random sampling. The subjects were invested using Egna Minnan Barndoms Uppfostran and Competitive Attitude Scale. Results: Good parenting pattern contributes to the form of benign com petitive attitude. Parents′denial and mother′s favor have predictive effect on benign competition atti-tude. Father′sdenial, father′s over-protection, and mother′s over-interference have predictive effecton vicious competition attitude. Conclusion:In the family education of medical students ,parents should change the education concept in order to form a good competitive attitude.
6.Effects of taurine on platelet aggregation induced by benzo pyrene in vitro activation function
Acta Universitatis Medicinalis Anhui 2015;(1):116-118
The peripheral renous blood which were taken from healthy volunteers and platelet was isolated. Platelet samples were randomly divided into six groups. The effects of different concentration of taurine( Tau) on benzo py-rene( BAP) induced platelet aggregation in vitro activation function were investigated by detecting the maximum platelet aggregation rate, the positive expression rates of platelet membrane surface CD62P and PAC-1. The results showed that platelet maximum aggregation rate had significant differences between each concentration of BAP-Tau groups and solvent control group in adenosine diphosphate(ADP) and collagen induced (P<0. 01). The positive expression rates of platelet membrane surface CD62 P and PAC-1 in BAP-Tau high concentration group had signifi-cant differences compared with solvent control group ( P<0. 01 ) . Different concentration of Tau could antagonize platelet function damage induced by BAP with a concentration gradient change.

10.Progress and assessment of total mesopancreas excision of pancreas
Chinese Journal of Digestive Surgery 2016;15(6):537-539
As no fiber sheath covered,mesopancreas is considered to be different from mesocolon and mesorectum.Though amount of lymphatic,nervous,vascular and fat tissues are consisted in this structure,the margin and range are still controversial in the clinical practice.Only a few clinical reports show a higher R0 resection rate with the procedure of total mesopancreas excision (TMpE),but most of the studies are singlecentered and retrospective,from which we could not assess the outcome improvement for the patients undergoing TMpE.Moreover,the difference between the ranges of TMpE and ever-used extended excision or lymphectomy should be further evaluated.More anatomical and clinical studies are needed to standardize the operation range in order to benefit the patients.
