Abstract］ objective to discuss radiological findings of parosteal osteosarcoma on emphasis combined with clinical pathology and literature.methods 4 cases of parosteal osteosarcoma proved by operation and pathology were analyzed retrospectively.results female was 3 cases,male was 1 case,average age was 30.5 years old,these tumors were arised on posterior border of distal femur and popliteal cavity,presented as lobular dense ossified mass,defined lesion.one case had villose margin.a thin narrow lucent zone separated the mass from the cortex at two cases.one case underwent angiography,there was no malignant feature.conclusion parosteal osteosarcoma may be divided into low-grade type and high-grade type.radiological manifestations of early stage possess character,early diagnosis conduces to establish rational treating plan and evaluate prognosis.

目的 结合临床病理学特征和文献资料，重点讨论皮质旁骨肉瘤的x线特征。方法收集经手术、病理证实的皮质旁骨肉瘤病例4例，对其进行回顾性分析。结果 4例患者女3例，男1例，平均年龄30.5岁，肿瘤均发生于股骨远端后侧和腘窝处，表现为分叶状致密骨化肿块，边界清晰，其中1例边缘呈绒毛状改变，2例有细窄透亮带与骨皮质相隔，1例行血管造影，未见血管池等恶性征象。结论皮质旁骨肉瘤分为低度恶性和高度恶性两种，早期影像学表现有特征性，早期诊断有助于制订相应的治疗方案和评估预后。

Objective:To detect the pathematology characteristic, pathematology types and the surgerical intervention effectiveness of verrucous carcinoma.

目的：探讨疣状癌的临床病理学特点及分型，以提高手术治疗效果。

Objective:To measure the volume and density of normal and pathological tonsil of human body,to search for the relevance between valume ,density and its tissue morphology.So as to provide the diagnostic basis for clinical medicine,anatomy,pathematology of human tonsil.

目的：检测正常腭扁桃体和不同病变程度的腭扁桃体的体积和组织密度，探讨其体积、密度与组织形态学的关联性，为临床医学、解剖学、病理学提供简便、可靠的科学依据。

Honeycombing with a basal and subpleural distribution (Fig 1) is regarded as pathognomonic , but not all cases of biopsy-proved UIP have this distinctive CT pattern.

Methods 56 patients with atrophic rhinitis(96 lateral)were treated by nasal submucou pediculated bone-suberiosteal muscle flap extracted from anterior wall of sinus maxillaries.

方法采用上颌窦前壁骨-骨膜肌瓣鼻腔粘骨膜下植入术治疗萎缩性鼻炎56例(96侧)，术后随访2～10年，根据术前术后临床症状、体征及病理学检查判断近远期治疗效果。

LIT was most commonly confused with malignant tumor, Crohn's disease, lymphoma and periappendicular abscess. There were 2 of 4 patients, who were performed operation. Most of our cases were not definitively diagnosed until the histopathologic examination after surgery and polymerase chain reaction.

大肠结核较易误诊为大肠肿瘤、克罗恩病、淋巴瘤和阑尾周围脓肿。4例剖腹手术者术中仍有2例(50%)被误诊为肿瘤和克罗恩病，即使活检或术后在病理学报告前仍有多数不能确诊。

Methods Seventy-five SD rats were randomized into five groups: normal, model, iodine glycerin (20 g/L), high-dose SP (200 g/L) and low-dose SP (100 g/L). The experimental periodontitis rat models were established by ligating molars with steel wire combined with intramuscularly injection of prednisolone (1.25mg, 8 times). Except that the model and normal groups were treated by applying saline, the other groups were treated by applying the corresponding drugs 0.5 mL to the peridentium, tid for 10 days. After treatment, debris index, probe depth and bleeding rate during probing were investigated and the pathological changes of periodontal tissues were also observed.

方法］SD大鼠随机分为正常组，模型组，碘甘油组(20g/L)，舒口散高、低剂量组(200、100 g/L)；采用钢丝结扎牙齿加肌注波尼松龙（l.25 mg/次，共8次）的方法复制大鼠实验性牙周炎模型；药物采用口腔局部涂搽，每次0.5mL，每日3次，10 d为1疗程，模型组与正常组给予等容积生理盐水；检测各组软垢指数、探诊深度、探诊出血阳性例数，并取牙周组织进行病理学检查。
