Diagnostic difficulties of pelvic splenosis: case report.

We report the case of a 38-year-old woman who presented with chronic lower abdominal pain. Her past medical history included a splenectomy due to abdominal trauma. Ultrasound examination revealed four pelvic tumors which, upon laparotomy, were found to be the result of splenosis. Approximately 100 cases of splenosis have been reported but only a minority of them have been published in the gynecological literature. Our case indicates that those involved in pelvic scanning (even of asymptomatic women) and/or treating those complaining of lower abdominal pain or presenting with pelvic tumors should be aware of splenosis as a possible diagnosis.     

内窥镜辅助下经口咽前路寰枢椎减压术

目的：探讨内窥镜辅助下经口咽前路寰枢椎减压术的临床效果。方法：1998年8月～2004年8月对38例陈旧性寰枢椎脱位患者采用内窥镜辅助下经口咽前入路减压术，其中18例行一期经口咽入路减压和后路枕颈内固定术：15例行经口咽前路寰枢椎复位钢板内固定术；5例不可复型仅行经口咽前入路减压术。结果：平均随访38个月（6～96个月）。术后患者临床症状均明显改善，上颈段脊髓减压改善率达89.3％。发生颅内感染1例，前路钢板松脱1例。结论：与常规减压方法相比，内窥镜辅助下经口咽前路寰枢椎减压手术创伤小，操作精细、准确，术中与助手可协同操作。     

膳食黑米皮抑制高脂诱导的家兔动脉粥样硬化形成及其机制的初步探讨

目的 探讨膳食黑米皮对高脂诱导的家兔动脉粥样硬化形成的影响及其作用机制。方法 24只雄性新西兰大耳白家兔,按体重随机分为3组,分别饲以正常基础饲料、高脂饲料(含96％基础饲料、0.5％胆固醇、3.5％猪油)、黑米皮饲料(含 91％基础饲料、0.5％胆固醇、3.5％猪油、5％黑米皮),实验期为 60d。用图像分析法测定各组家兔主动脉脂质斑块面积,并分析家兔氧化与抗氧化状态。结果 黑米皮实验家兔的主动脉壁斑块面积较高脂组低66%(P<0.001);黑米皮组实验家兔的主动脉壁8-ohdG含量和血清及主动脉壁中MDA水平也低于高脂组(P<0.05 );而红细胞及主动脉壁中SOD水平和血清α-生育酚含量在两个处理组之间差异无显著性。结论 膳食黑米皮可以抑制高脂诱导的家兔动脉粥样硬化形成,其机制可能与之降低机体氧化应激水平及过氧化脂质生成有关。     

应用动力髁螺钉联合骨肽注射液治疗股骨髁上骨不连疗效观察

目的观察应用动力髁螺钉联合骨肽注射液治疗股骨髁上骨不连的疗效。方法53例股骨髁上骨不连患者随机分为两组：对照组（26例）和治疗组（27例）,两组均应用动力髁螺钉治疗,治疗组加用骨肽注射液治疗。随访,进行疗效评价,记录骨愈合时间和测定疼痛指数。结果治疗组疗效优于对照组。结论应用动力髁螺钉联合骨肽注射液治疗股骨髁上骨不连可提高疗效。     

浅谈基层医院如何掌握胆囊息肉样病变手术指征

胆囊息肉病变(PLG)临床并不少见,手术是根治的主要方法,但并非所有胆囊息肉都需手术治疗。因其病变类型不同,大小不一,疾病转归亦不尽相同,因此其手术适应证各家医院掌握也不一致。我院自1996年1月至2006年6月共收治胆囊息肉病人128例,其中手术切除胆囊119例,具体分析如下。     

组织扩张术皮肤胶原的代谢改变

目的：研究常规扩张（ＩＴＥ）和持续快速扩张（ＣＴＥ）对皮肤胶原代谢的影响。方法用白色小家猪制作组织扩张术动物模型，用Ｇｏｒｄｅｌａｄｚｅ法测定血清和扩张组织的羟脯氨酸（ＨＰ）含量，藻酸盐印模材膜片法测量标记区面积；光镜测量真皮厚度。结果：ＩＴＥ组血清ＨＰ含量升高，０．８倍，ＣＴＥ组升高１．２倍，ＩＴＥ和ＣＴＥ组皮肤含量与正常皮肤相同，组织中ＨＰ总量均明显升高，持续扩张皮瓣组（ＣＴＥＦ）术后４ｗｋ皮     

Active management of infertility.

Management of infertility is slow, time consuming and, paradoxically, costly. It needs to be streamlined so that diagnosis and management go hand in hand with proper division between primary physicians at district level and highly trained specialists at regional level. Incorporation of assisted conception techniques is the key to the success of such an approach.     

The surgical removal of mandibular third molars: a study in decision making.

OBJECTIVE: The aim of this study was to investigate and analyze the angulation of and the various indications for removal of mandibular third molars in Jordanians as a representative Arab sample. METHOD AND MATERIALS: The data included in this retrospective study were obtained from the clinical and radiographic records of 1,282 patients undergoing mandibular third molar surgery during a 5-year period from 1994 to 1999. The indications for removal of the mandibular third molars were classified in accordance with age and gender. The angular position of mandibular third molars was registered. RESULTS: A total of 2,252 mandibular third molars were removed from 740 male patients (57.7%) and 542 female patients (42.3%) aged 14 to 67 years. Pericoronitis was the most common indication for surgery, affecting 1,055 teeth (46.8%). Caries was observed in 519 third molars (23.0%). The vertical angular position was most commonly found (1,383 teeth; 61.4%) followed by the mesioangular position (407 teeth; 18.1%). CONCLUSION: The results obtained in this study are similar to those reported in earlier studies carried out elsewhere, although the incidence of periodontitis among Jordanians was significantly higher and occurred in older patients, and prophylactic removal was performed less frequently than has been reported in other countries.     

医院后勤服务社会化实践中的几点思考

就医院后勤服务社会化的实际操作中的几个问题进行了论述,指出实行后勤社会化服务,必须有相应的外部环境;后勤部门实行企业化管理,必须有相配套的政策作保障;实施商品化服务,必须有对等的经济意识;加大后勤服务化的力度,必须有果敢超前的决策意识。     

Pathological changes in testes and liver of male albino rats after dermal exposure to DDVP insecticide.

Exposure of male albino rats to DDVP insecticide at sublethal dose of 30 mg/kg/day through dermal painting for a period of 90 days didn't show any intoxication symptoms or mortality. However, cytopathological changes in testicular and liver tissues were evident. There was a positive correlation between the degree of cellular damage and the period of insecticide administration. In general, damages were prominent in rats treated for 30 days or more. Histological examination of testes showed degenerative seminiferous tubules and fewer leydig cells. Hepatic cells were congested, atrophied and showed different stages of necrobiotic changes. This suggests a great care and caution for workers during different phases of DDVP insecticide handling.
