The coupling of the pre-stressed therma. insula.ed tubing string broke down inside the stea. flooding welts, a.ter the tubing were used in high tempera.ure a.d high pressure stea. for a.out two yea.s. With further check, it wa. found tha. most of the weld joints between the inner a.d outer tubing a.so cra.ked. The fa.lure a.a.ysis for the a.cidents ha. been ca.ried out by the a.a.ysis of chemica. composition for the steels, microstructure observa.ion, mecha.ica. property tests, a.d the investiga.ion of the service environment etc.. The results show tha. the ea.ly da.a.e of the pre-stressed therma. insula.ed tubing string is ma.nly induced by the ca.stic stress corrosion, which ca. be strengthened by a. unsta.le microstructure of the coupling serviced a. high tempera.ure for a.long time. Moreover, the high pre-stress design on the therma. insula.ed pipe for the cyclic stea. injection ma. be not suita.le to the situa.ion of stea. flooding, which would result in the weld joint cra.king.

Propylthioura.yl (PTU)-rela.ed liver toxicity is likely to oc- cur in a.out 1% of trea.ed pa.ients. In ca.e of a.ute or suba.ute hepa.itis, liver fa.lure ma. occur in a.out one third. We report two further ca.es of PTU-induced sub- a.ute hepa.itis, in whom the dela. between occurrence of liver da.a.e a.ter the initia.ion of trea.ment, the un- derestima.ion of its severity a.d the dela.ed withdra.a. of the drug were a.l likely responsible for liver fa.lure. The high incidence of liver toxicity rela.ed to PTU, its potentia. severity a.d dela.ed occurrence a.ter initia.ion of trea.ment a.e in fa.or of monthly a.a.ine a.inotra.s- fera.e monitoring, a. lea.t during the first six months of thera.y.

Ea.ly screening for colorecta. ca.cer(CRC) holds the key to comba. a.d control the increa.ing globa. burden of CRC morbidity a.d morta.ity.

This will a.low for the differentia.ion of the genera. popula.ion from high risk individua.s. Colonoscopy would then become the seconda.y test, to further screen the high risk segment of the popula.ion. This will encoura.e pa.ticipa.ion a.d therefore help to rea.h the goa. of ea.ly detection a.d thereby reduce the a.ticipa.ed increa.ing globa. CRC incidence ra.e. a.blood-ba.ed screening test is a.a.pea.ing a.terna.ive a. it is non-inva.ive a.d poses minima. risk to pa.ients. It is ea.y to perform, ca. be repea.ed a. shorter interva.s, a.d therefore would likely lea. to a.much higher pa.ticipa.ion ra.e.
