BACKGROUND:Quality of life (QL) is a concept which reflects the physical, social, and emotional attitudes and behaviours of an individual. QL assessment is becoming in- creasingly recognised as an outcome and predictor for can- cer patients. Although hepatectomy has been widely ac- cepted as treatment of choice to offer a chance of cure for patients with liver cancer, little is known about the subjec- tive clinical results after this operation. This prospective study was designed to evaluate the Pre- and postoperative quality of life in patients with liver cancer. METHODS: The quality of life of 36 consecutive patients was measured using gastrointestinal quality of life index (GQLI) regularly 2 years after the operation, starting with a preoperative measurement. RESULTS: The score of mean preoperative GQLI was 106 ± 13 points, and it was reduced significantly 2-10 weeks after the operation (86-98) (P 0. 05 ). In the patients who survived more than 9 months, the GQLI score was higher than that before the operation. Major hepatectomy (lobectomy and combined segmentectomy) reduced the GQLI score more evidently than did minor hepatectomy (simple segmentec- tomy ) in 2-5 weeks after the operation (P siONS: The assessment of the quality of life is meaningful for patients with liver cancer. Tumor recur- rence, poor liver function and major operation are the most important factors for reducing the quality of life. He- patic resection is justified by its effects on the survival and the quality of life of the patients.

The effects of adding Al(i-C_4H_9)_3 (TBA) to rac-Me2si(Ind)2ZrCl2/ MAO catalyzed propylene-1-octene copolymerization were studied. At TBA /MAO (Al/AI mole ratio) of about 0.6, the polymerization activity was found to be much higher than the system without TBA. Increases of polymer molecular weight and 1-octene content from addition of TBA were also observed.

The multiple scattering cluster (MSC) method has been employed to perform a theoretical analysis on carbon is near edge X-ray absorption fine structure of the deuteron acetylene (C2 D2) adsorbed on si(111)7× 7 at room temperature. From the MSC study. it is confirmed that the (22D2 molecule is bonded to a pair of adjacent si adatom and si restatom with C-si bond length about 0.18nm. The carbon-deuteron bond is bent away front the surface and the CCD bond angle is about 120°. The molecule plane tilt slightly away from the surface normal. Compared with C2D2 in gas phase, the C-C bond and C-D bond are elongated by about 0.03nm and 0.02nm respectively when acetylene was adsorbed on the subtrate.

A novel model for the 1: 2 complex of piperazine with some phenols in solution is established and verified. In CDCl3 solution, one piperazine molecule is tied to two phenol molecules by hydrogen bonds of O-H---N and N-H---O. And the protons of >NH and -OH groups exchange quickly and simultaneously between the atoms of phenol oxygen and piperazine nitrogen.
