Objective To analyze the differences of coagulation parameters between patients with advanced schistosomiasis cirrhosis and hepatitis B cirrhosis under different degrees of liver function,so as to provide the evidence for further guidance of judging clinical condition and prognosis. Methods Sixty?three patients with advanced schistosomiasis cirrhosis and eighty pa?tients with hepatitis B induced cirrhosis hospitalized in Jingzhou Central Hospital from January 2014 to June 2016 were served as an advanced schistosomiasis cirrhosis group and a hepatitis B cirrhosis group,respectively,and ninety?six gastropathy pa?tients excluded from other diseases that might affect coagulation in the same period were served as a control group. The levels of PT,INR,Fib,TT,APTT,and PLT of the patients among the above 3 groups and the cirrhosis patients with different Child?Pugh classes were detected and compared. Results The differences of the levels of PT,INR,Fib,TT,APTT,and PLT among the 3 groups were statistically significant(F=84.512,81.672,37.612,104.475,52.497,102.233;all P<0.05). The further analysis showed that PT,INR,TT,and APTT of both the advanced schistosomiasis cirrhosis and hepatitis B induced cirrhosis groups were longer than those of the control group,and the PLT levels of both the former 2 groups were lower than that of the con?trol group(all P<0.05). Compared with the advanced schistosomiasis cirrhosis group,PT,INR,TT,and APTT of the hepati?tis B induced cirrhosis group were longer,and the levels of Fib and PLT were lower(all P<0.05). Among those with the liver function of Grade A,the reduced degree of PLT in the patients with hepatitis B induced cirrhosis was more serious,while for those with the liver function of Grade B and C,the difference between the patients with advanced schistosomiasis cirrhosis and hepatitis B induced cirrhosis was not statistically significant(both P > 0.05). Under all the grades of liver function,TT and APTT of the hepatitis B induced cirrhosis group was longer than those of the advanced schistosomiasis cirrhosis group ,and the Fib level of the former was lower than that of the latter. Among those with the liver function of Grade A and B ,PT and INR of the hepatitis B induced cirrhosis group were longer than those of the advanced schistosomiasis cirrhosis group;while for those with the liver function of Grade C,the difference between the two groups was not statistically significant(all P > 0.05). Conclu?sions There exist differences of the damage degrees of coagulation function between the patients with advanced schistosomiasis cirrhosis and hepatitis B cirrhosis. When the damage degree of the liver function is lighter,the coagulation function in the pa?tients with hepatitis B cirrhosis decreases more significantly;when the damage degree becomes more severe,APPT in the pa?tients with hepatitis B cirrhosis extends more significantly,while the differences of PLT and PT between them are little.

BACKGROUND: Although shape memory alloy has been extensively used in modem medicine, including orthopaedics and dental surgery, the body fluid could influence the stability of biomaterial and some ions released by materials may cause toxic and side effect to human body. The technology for the modification of shape-memory materials is of crucial importance for clinical use of shape memory alloy.OBJECTIVE: To investigate the biocompatibility of diamond-like carbon (DLC) coated Nickel-Titanium shape memory alloy and uncoated shape memory alloy with osteoblasts cultured in vitro. DESIGN, TIME AND SETTING: A comparative observation. The study was performed at the Institute of Othopaedics of Lanzhou University from March to June 2005.MATERIALS: A total of 30 DLC-coated Nickel-Titanium shape memory alloy disks, 6 minx7 mmx0.5 mm, and the same amount of uncoated ones of equal size were provided by College of Materials, Lanzhou University. METHODS: Rabbit osteoblast suspension of the third passage at density of 10 × 108/L were incubated with DLC-coated Nickel-Titanium shape memory alloy disks and uncoated shape memory alloy in 12-well culture plate in 5% CO2 at 37 ℃.MAIN OUTCOME MEASURES: Culture media were counted at 1, 2, 3, 4 and 5 days of culture to determine alkaline phosphatase (AKP) activity and nickel (Ni2+) concentration.RESULTS: The proliferation of osteoblasts and the concentration of AKP in DLC- coated group were greater than uncoated group; while the uncoated group released more Ni2. into the cells culture media than coated group (P < 0.05). CONCLUSION: DLC-ceated Nickel-Titanium shape memory alloy appears to have better biocompatibility with osteoblast cultured in vitro compared to uncoated ones.

New Chemical Entities (NCEs) development is a systematic long-term project that involves multiple disciplines. The translation research will help to build an advanced R&D system from the basic laboratory research, preclinical studies and clinical evaluation to clinical application of drug, for the purpose of shortening the R&D cycle and accelerate the launch of new drugs. In new drug R&D and its clinical application, drug disposition (absorption, distribution, metabolism, excretion, ADME) properties are important criteria for assessing drug-likeness of candidates. ADME evaluation of NCEs plays an important role in the translation research throughout innovative drug R&D process. Therefore, ADME evaluation at the early stage of drug design and development will be helpful to improve the success rate and reduce costs, and further access to safe, effective drugs.
