These results are quite remarkable since these algebras do not admit appropriate sl2triples.


When one expands a Schur function in terms of the irreducible characters of the symplectic (or orthogonal) group, the coefficient of the trivial character is 0 unless the indexing partition has an appropriate form.


It is shown that this is possible when the window g ε L2(?) generating the WeylHeisenberg frame satisfies an appropriate regularity condition at the integers.


In particular, the results in this article show that the oscillations of a function at large scale are comparable to the oscillations of its samples on an appropriate discrete set of points.


Under the appropriate definition of sampling density D?, a function f that belongs to a shift invariant space can be reconstructed in a stable way from its nonuniform samples only if D?≥1.

 The aim of replantation is not only to obtain survival of the replantedlimb, but also to achieve a satisfactory function. Since 1972, a total of88 limb or digital replantations have been performed, with 67 survivors(76%), their age ranging from 4 to 56 years. Every case has been followed up regularly, and 3/4 of them have satisfactory function. The factors which determine the functional results of the replantedlimbs are:1. Age. No patient over 50 years of age had obtained excellent functional result.2. The... The aim of replantation is not only to obtain survival of the replantedlimb, but also to achieve a satisfactory function. Since 1972, a total of88 limb or digital replantations have been performed, with 67 survivors(76%), their age ranging from 4 to 56 years. Every case has been followed up regularly, and 3/4 of them have satisfactory function. The factors which determine the functional results of the replantedlimbs are:1. Age. No patient over 50 years of age had obtained excellent functional result.2. The duration of limb ischemia. When the durtion of ischemia was less then 8 hours, there were 33 survivors out of 40 replantations, and 15 of them obtained excellent results (Grade I); whereas it exceeded 8 hours, there were 34 survivors among 48 replantations, and only 4 of them obtained excellent results.3. The temperature of amputated ischemic limb. High ambient temperature had definite deleterious effect on amputated limbs. However, the way of storage of the detached limb affected the deleterious effect to certain extent. We had a case of amputation through the upper arm being stored with good cooling for 20 hours. Replantation was performed and movement of the fingers regained 2 years afterward.4. The nature of injury. Amputation with extensive local tissue damage usually does not result in good function.5. As to the chance of obtaining good functional result after replantation, complete major amputation is definitely inferior to the incomplete major amputation. In case of amputation with severe local crush of all the four fingers, which could not be replanted in situ, a better way to deal with this condition is to transplant the relatively suitable fingers available to the positions of the index and middle fingers.6. After major replantation, functional results vary mainly with the recovering condition of the injuried nerves and the flexibility of the small joints of fingers. In palm and digital replantations, the functi onal results were mainly affected by the severity of the damage of the local bones and joints, particularly the metacarpophalangeal joints, and the gliding mechanism of the tendons.7. To obtain a good functional result after replantation, appropriate opera tive procedures and meticulous postoperative management are manda tory.  本文报告再植存活断肢67例的随访结果,提出功能考核的分级标准,对影响功能效果的因素,进行了讨论。年轻伤员,整齐的断离伤,缺血时间在8小时以内的断肢,再植后常能获得良好功能。  Six cases of toetohand transplantation by microvascular anastomosisare reported. The second toe was usually selected from the patient'sopposite foot for the reconstruction of his hand. In these cases, thedorsalis pedis artery(in 3 cases) or the plantar metatarsal artery(in 1 case) was anastomosed to the radial artery, but only onevein was anastomosed. Tendons were repaired by appropriate rearrangement. Repairing of the nerves was necessary and imperative.Among them four cases had successful transplantations...

Tendons were repaired by appropriate rearrangement. Repairing of the nerves was necessary and imperative.Among them four cases had successful transplantations with satisfactory function of the new thumb or finger. As a matter of fact two caseshad failed as a result of injury to the arteries of the toes. It is considered that dissection of the toe is very important, and the whole operation should be carried out meticulously and carefully.  本文报告应用第二足趾游离移植再造拇指或手指6例。讨论了应用第二趾的优点,切取好第二趾是手术成功的关键。介绍了移植操作要点及第2～5指的再造。  Thirtynine cases of congenital talipes equinovarus have been treated in our hospital from August 1963 through July 1966. In 30 of those with complete followup the youngest when first seen in our department was less than one month old, and the oldest 11 years old. The longest followup period was 14 years and 11 months, and the shortest one year.Method of Treatment:1.

Thirtynine cases of congenital talipes equinovarus have been treated in our hospital from August 1963 through July 1966. In 30 of those with complete followup the youngest when first seen in our department was less than one month old, and the oldest 11 years old. The longest followup period was 14 years and 11 months, and the shortest one year.Method of Treatment:1. Patients under 5 years of ageNonKite's method of oast correction hadbeen routinely used up to April 1964, and then, with the idea of shortening the course of treatment especially in those moderate and severe cases, Kite's method was used and supplemented by subcutaneous tenotomy of the heel cord, by which the time required for a complete correction was cut down from 30.9 weeks on the average by nonKite's method to an average of 13.3 weeks by the combined treatment. The result of these two forms of treatment on 31 feet of 21 cases was excellent in 23 feet, good in 7 and fair in one.2. Patients above 5 years of age or recurrent casesThe treatment was mainlysurgical. The procedures adopted in this group of oases comprised lengthening of tendocalcaneus (11 feet), cast correction maintained with Kirschner's wire fixation (1 foot), capsulotomy of tarsometatargal joints (4 feet), triple arthrodesis (2 feet), fusion of the calcaneocuboid joint (1 foot) and medial soft tissue releasing operations (9 feet). These operations were actually done on 15 feet (most of these feet had undergone more than one operation) of 9 cases with good result in 70% of the feet.In summary, congenital talipes equinovarus should be treated as early as possible, preferably with Kite's correction cast, and supplemented by tenotomy if necessary. In older children with severe deformities or in recurrent cases, appropriate surgical measures should be resorted to.  本文介绍华山医院骨科自1963年8月～1966年7月治疗先天性马蹄内翻足39例,有随访记录的30例。就诊年龄最小的1月以内,最大11岁。随访时间最长14年11月,最短1年。临床经验,明确了先天性马蹄内翻足应尽早治疗,用Kite石膏矫正法,必要时加做跟腱切断术,疗程明显缩短。对畸形严重的较大儿童或复发病例应采取相应的手术治疗,后者包括跟腱延长、石膏矫正伴克氏针固定、蹠跗关节切开、三关节融合、跟骰关节融合、足内侧软组织松解等术,多数病例且不止手术一次。   << 更多相关文摘
