扁桃体周脓肿感染途径的探讨

为探讨扁桃体周脓肿的真正发病机理、感染途径，对连续诊治的１３１例扁周脓肿患者进行研究。其中８３例患侧的扁桃体被切除，切除之扁桃体外侧面均平整。通过８３例组织学观察，扁桃体上极表面既无扁桃溃破亦无脓瘘，邻接扁桃体上方之软腭粘膜下发现有感染及／或纤维化的小唾液腺（Ｗｅｂｅｒ腺），这些与扁桃体相邻的腺体在其他非扁周脓肿患者则显示正常形态与结构。从而认为扁桃体周围的化脓性感染可能与Ｗｅｂｅｒ腺有关，而非急性扁桃体炎。主张早期扁桃体切除术治疗扁周脓肿，目的在于获得充分引流。     

卵巢上皮性癌155例的治疗与预后

目的：探讨卵巢上皮性癌的治疗与影响预后的因素。方法：对１９７０年１月至１９９２年１２月在我院治疗的１５５例卵巢上皮性癌进行回顾性分析。全部手术切除标本经病理检查诊断并按ＦＩＧＯ分期标准进行分期，４２例行２次手术，４例行３次手术。除６例外，余１４９例均于手术后行化疗，３２例于第２次术后再次行化疗，９例因复发再次化疗。结果：２年、５年、１０年的生存率分别为Ⅰ期９２．４％、８７．０％、７０．６％；Ⅱ期９１．９％、６３．６％、４７．８％；Ⅲ期５９．９％、３８．２％、１９．２％；Ⅳ期２５．０％、２５．０％、０．０％（Ｐ＜０．００１）。６例未化疗者均在术后２年内死亡。结果表明，预后与临床分期、细胞分化、残留癌灶大小有关。５年生存率中，Ⅰ期为８７．０％和Ⅲ期为３８．２％（Ｐ＜０．００１）；Ｇ１的５年生存率为９５．９％，Ｇ３为１１．８％（Ｐ＜０．００１）；无残留癌灶者为９７．６％，残留癌灶＞２ｃｍ者为２１．２％（Ｐ＜０．００１）。结论：在卵巢上皮性癌初次手术时残留癌灶＜２ｃｍ，并于术后尽早开始化疗，可提高生存率。     

Construct Validity of the EQ-5D in Low-Income Chinese American Primary Care Patients

OBJECTIVES: Although the EQ-5D has been used with increasing frequency to measure health-related quality of life, to date, the measure's validity has not been examined in Chinese American immigrants. We evaluated the construct validity of the EQ-5D by testing its performance with respect to sociodemographic and clinical characteristics of the population and comparing responses on the EQ dimensions with the SF-36 subscales. METHODS: The study surveyed low-income Chinese patients attending a community health center in New York City's Chinatown. Participants received self-administered versions of the EQ-5D and SF-36 and additional questions regarding demographic and clinical information. RESULTS: 856 patients were approached and data were collected from 523 patients (61%). Analysis of the EQ-5D responses by sociodemographic and clinical variables found significant differences among categories of age, gender, marital status, number of medical problems, self-rated health, and specific medical problems. Correlations between similar dimensions and subscale scores were stronger between the two measures than dissimilar ones. Patients without impairments on a given EQ dimension tended to have higher SF-36 subscale scores than patients reporting 'any' impairment (i.e. some/moderate or severe). CONCLUSIONS: The results provide initial support for the construct validity of the EQ-5D in our sample. Further studies should compare the performance of the EQ-5D with other preference-based measures in Chinese persons and examine the valuations that both low-income and Chinese persons place on core aspects of health.

Construction of a bioengineered cardiac graft

OBJECTIVES: Currently available graft materials for repair of congenital heart defects cause significant morbidity and mortality because of their lack of growth potential. An autologous cell-seeded graft may improve patient outcomes. We report our initial experience with the construction of a biodegradable graft seeded with cultured rat or human cells and identify their 3-dimensional growth characteristics. METHODS: Fetal rat ventricular cardiomyocytes, stomach smooth muscle cells, skin fibroblasts, and adult human atrial and ventricular cardiomyocytes were isolated and cultured in vitro. These cells were injected into or laid onto biodegradable gelatin meshes, and their rate of proliferation and spatial location within the mesh was evaluated by using a cell counter and histologic analysis. RESULTS: Rat cardiomyocytes, smooth muscle cells, and fibroblasts demonstrated steady proliferation over 3 to 4 weeks. The gelatin mesh was slowly degraded, but this process was most rapid after seeding with fibroblasts. Human atrial cardiomyocytes proliferated within the gelatin meshes but at a slower rate than that of fetal rat cardiomyocytes. Human ventricular cardiomyocytes survived within the gelatin mesh matrix but did not increase in number during the 2-week duration of evaluation. Grafts seeded with rat ventricular cells exhibited spontaneous rhythmic contractility. All cell types preferentially migrated to the uppermost surface of each graft and formed a 300- to 500-microm thick layer. CONCLUSIONS: Fetal rat ventricular cardiomyocytes, gastric smooth muscle cells, skin fibroblasts, and adult human atrial cardiomyocytes can grow in a 3-dimensional pattern within a biodegradable gelatin mesh. Similar autologous cell-seeded constructs may eventually be applied to repair congenital heart defects.

Vascular endothelial growth factor expressing mesenchymal stem cells improves cardiac function in chronic myocardial infarction in pigs

Transplantation of mesenchymal stem cells （MSCs） for myocardial reconstruction has shown promise in both animal models and human phase 1 clinical studies. Vascular endothelial growth factor （VEGF） is a strong therapeutic agent for treating ischaemia by inducing angiogenesis. The feasibility of ex vivo MSCs mediated gene transfer is documented. Matsumoto and colleagues have recently reported genetically engineered MSCs carrying VEGF165 delivery for revascularization in a model of acute myocardial infarction （MI）. The promising data from our laboratory in both angiogenesis and MSCs transplantation in cunicular heart model of acute MI have prompted us to attempt the combined and simultaneous application of the two strategies.
