Tea, one of the most popular consumed worldwide beverages, is known to be rich in polyphenols, more particularly in catechins. An amperometric biosensor based on tyrosinase was developed in order to monitor the phenolic content in black and green teas. The enzyme was immobilised by coreticulation with glutaraldehyde on carbon screen-printed electrodes (CSPE). Initially, the performances of the biosensor were evaluated referring to catechol as a model substrate. This analytical tool exhibits a high sensitivity (217 nA/μM), low limit of detection (LOD) = 0.03 μM, good intra-electrode and inter-electrode reproducibilities with RSD lower than 3% (n = 5 injections) and RSD = 8.14% (n = 12 sensors) respectively. The storage stability was also studied;the biosensor retained successively 85% and 70% of its initial response after 34 and 53 days. Subsequently, several catechin derivatives frequently found in teas were tested and classified relatively to their sensitivities. For tea samples, the results obtained with the biosensors were compared to high performance liquid chromatography (HPLC) analysis. A good correlation between the two methods was obtained. The calculated recovery was between 90% and 96%, proving that the proposed tyrosinase biosensor can be an alternative analytical tool for global determination of catechin derivatives in tea.

目的针对后交叉韧带（posterior cruciate ligament，PCL）保留型膝关节假体置换术进行15年以上临床随访研究，分析其临床疗效及失败原因。方法对Medico-Chirurgical du Cedre中心1990年9月至1992年3月行PCL保留型全膝关节假体初次置换术获得随访的153例（178膝）患者的临床资料进行回顾性研究。对其采用术后X线测量结合随访时国际膝关节协会临床评分评估手术疗效，X线测量包括髋膝踝角（HKA）平均值、HKA绝对偏差、α角、β角、髌骨指数（AP／AT）、胫骨后倾角（PTA）等。以翻修率作为假体生存率最终评定标准。结果153例患者随访时31例（49膝）死亡，4例（4膝）失访，获访118例（125膝）。翻修11膝，15年以上假体生存率93．7％。翻修11膝原因分别为：9膝为假体界面无菌性松动（其中7膝伴严重骨溶解，2膝为胫骨假体周围透亮线伴疼痛），1膝反曲畸形，1膝内侧胫骨平台塌陷。术后随访时膝关节协会评分达173分，优良率95．9％。对比翻修患者与未翻修患者临床资料：对侧未手术膝关节内外翻角、术前正位X线片B角、两组手术前后膝关节协会评分差异均有统计学意义（P〈0．05）。结论PCL保留型假体可以较好地恢复膝关节生物力学特性，15年以上生存率优良。仅个别病例失败与PCL失效有关，聚乙烯衬垫后部过度磨损和髌股关节并发症少见。未手术侧膝关节畸形程度和术侧膝关节胫骨侧内翻畸形程度可能是影响假体翻修率的重要因素。

＜正＞ A new tool dedicated to 300mm silicon metrology is presented. It is based on an infrared spectroscopic ellipsometer （IRSE）. Generally applied in the visible range this technique has long been recognized as very powerful to characterize thin films and multilayer structures and it is now routinely used for non-destructive on-line characterization of semiconductor process. Up to now, infrared spectroscopic ellipsometry has not seen the same development. R＆D tools have been developed by various providers including SOPRA, but the performances were not sufficient to allow a real industrial characterization. The measurement is generally
