Multicentric fibromatosis of familial inheritance

This is an unusual case presentation of a young woman with a clinical history and course simulating juvenile hyaline fibromatosis, but without hyalinization in the stroma. Because of the age of onset, the apparent familial inheritance, the nonaggressive and nonregressive tumor traits, the disease cannot be classified as multicentric fibromatosis. Therefore, we are referring to this case as multicentric fibromatosis with familial inheritance, a previously unreported entity to our knowledge.

断肢断腕断掌再植后手内在肌挛缩51例分析

探讨断肢断腕断掌再植术后手内在肌挛缩的发病机理,结合临床经验提出分类、预防和治疗方法。方法:对51例断肢(腕、掌)再植,分别采用术中切开骨间肌肌筋膜、掌腱膜及腕横韧带;术后严重肿胀时早期切开骨筋膜室;缺血时间超过10小时者,除上述措施外尚须切断或部分切除拇收肌和骨间肌肌腹。结果:采用上述预防措施后,手内在肌挛缩的发生率明显降低。结论:本症重在预防,如能及时、果断地采取措施,效果良好。一旦发生中、重度手内在肌挛缩应尽早手术。     

动脉灌注灭活再植治疗骨肉瘤的体会

本组１２例骨肉瘤均采用动脉区域灌注灭活再植及术后化疗方法，术后２年存活率平均为７５％，１例因经验不足致局部复发，仅占８．３％，表明在化疗保障下，采用此种方法即能保肢，又能获得与截肢治疗相同的手术效果，优于单纯行灭活再植术后中方法。     

幽门螺杆菌粘附作用的体外研究

置幽门螺杆菌(HP)悬液于含人喉癌上皮细胞(Hep-2)或人胃癌上皮细胞(MKN-28)的培养瓶内,经2h或3.5h培养后观察HP对细胞的粘附情况。结果发现HP能成丛地粘附在上皮细胞表面,少数侵入胞浆内。HP对MKN-28粘附率明显高于对Hep-2细胞者。随菌龄的延长或菌株的变异,HP的粘附作用明显减弱。1%D-甘露糖对HP的粘附性有部分阻抑作用。     

金丹肝泰1号对大鼠急性肝损伤防治作用的实验研究

用D-氨基半乳糖（D-GaIN）制备大鼠急性肝损伤模型。方法：检测血清丙氨酸氨基转氨酶（ALT）和血清天门冬氨酸氨基转氨酶（AST）的活性，观察光镜下肝组织的病理学改变，探讨对急性肝损伤的保护作用。结果：口服浸膏可显降低急性肝损伤大鼠血清ALT和AST水平，减轻肝细胞的变性坏死，其作用强度与肝炎宁相当，但弱于联苯双酯。     

Cancer mortality among shoe manufacturing workers: an analysis of two cohorts.

OBJECTIVES: To examine the cancer risk of shoe manufacturing workers and evaluate whether the risk was associated with exposure to leather dust and solvents. METHODS: Data from two historical cohort studies of shoe workers were expanded and analysed in parallel. A total of 4215 shoemakers from England contributing 103 726 person-years at risk and 2008 shoemakers from Florence, Italy, contributing 54,395 person-years at risk were included in the analysis. Exposure to leather dusts and solvents from glues was evaluated on the basis of job title information. Standardised mortality ratios (SMR) were calculated as ratios of observed deaths (Obs) over expected derived from national mortalities. RESULTS: Overall mortality was lower than expected in both cohorts (English cohort: Obs 3314, SMR 81, 95% confidence interval (95% CI) 78-84; Florence cohort: Obs 333, SMR 87, 95% CI 78-97). An increased risk of nasal cancer was found (English cohort: Obs 12, SMR 741; Florence cohort: Obs 1, SMR 909). 10 of the 13 cases occurred among English workers employed in the manufacture of welted boots (SMR 926, 95% CI 444-1703), a sector of the industry thought to have had the highest exposure to leather dust. Mortality from leukaemia was not increased in the English cohort (Obs 16, SMR 89), but was increased in the Florence cohort (Obs 8, SMR 214, 95% CI 92-421); and the highest risk was found among shoe workers in Florence who were first exposed between 1950 and 1959 when exposure to benzene was substantial (Obs 3, SMR 536, 95% CI 111-1566). Some evidence for an excess risk of stomach, bladder, and kidney cancer, as well as multiple myeloma and non-Hodgkin's lymphoma was also found in the Florence cohort only among workers employed in jobs with the highest exposure to solvents. CONCLUSIONS: These findings confirm the associations between exposure to leather dust and nasal cancer and between exposure to benzene and leukaemia in the shoe manufacturing industry and suggest that the risk of other cancers may be increased among workers exposed to solvents or glues.     

CT造影剂碘海醇注射液的制备及动物实验

本文报道了非离子型Ｘ－ＣＴ造影剂碘海醇注射液的制备及动物实验结果。磺海醇的最大吸收波长λ＿（ｍａｘ）为２４４ｎｍ。讨论了温度、浓度对磺海醇溶液粘度的影响：粘度随温度的升高而下降，呈负线型相关；粘度随浓度（Ｃ）升高而激剧升高，与浓度的四次方呈线性相关：Ｖ＿（３７℃）＝４７２．５８９［Ｃ］￣４＋１．１２１（ｒ＝０．９９７７）Ｖ＿（３０℃）＝６６３．８１３［Ｃ］￣４＋１．１５２（ｒ＝０．９９９６）Ｖ＿（２０℃）＝１０８２．９５３［Ｃ］￣４＋１．４３３（ｒ＝０．９９８２）使用该注射液进行狗的造影实验，获得了清晰的造影图像。     

化工行业职业性机械伤害危险因素的病例-交叉方法研究

目的 研究化工行业机械伤害的有关诱发因素，估计其作用强度。方法 采用病例-交叉设计的方法。以操作和检修时受伤的化工工人为研究对象，每个对象在受伤后2d内完成调查，收集他们受伤前10min、上一工作日同一段时间和受伤前1周内有关诱发因素暴露的信息，用配对时间段方法和一般频数法进行分析，评估各种诱发因素的危险度。结果 一般频数法分析的结构表明，操作方法异常、设备工具缺陷、工作紧迫、注意力不集中、不使用防护用品、精神状况较差、与同事配合不协调、工作环境发生变化等瞬时危害因素的RR值及95%可信限的下限均大于1。配对时间段方法分析的结果与其相拟，但95%可信限较宽。结论 化工行业职业性机械伤害的发生存在着诸多诱发因素。病例-交叉研究中的一般频数法与配对时间段方法相比，前者所得结果较为可靠，研究的相对效率较高。建议进一步使用多个时间段方法进行研究，以减小混杂因素的影响。     

Indirect carotid-cavernous sinus fistula: transvenous embolization from the external jugular vein using a superior ophthalmic vein approach. A case report

A case of indirect carotid-cavernous sinus fistula treated by combined transarterial and transvenous embolization is described. A 49-year-old woman with a right indirect carotid-cavernous sinus fistula draining solely to the right superior ophthalmic vein was treated first by transarterial embolization with polyvinyl alcohol particles. Then, by approaching through the superior ophthalmic vein from the right external jugular vein, the cavernous sinus was embolized with platinum wire using a tracker microcatheter, which resulted in marked clinical improvement. Transvenous embolization by approaching from the external jugular vein through the superior ophthalmic vein represents a promising alternative when shunted blood drains anteriorly to the superior ophthalmic vein.
