We found out one kind of new orange-red long afterglow material La2O2S: Eu3+, Mg, Zr.2 In the phosphor Gd2O2S, Mg, Ti which was prepared by high-temperature solid-state method, the orange afterglow phenomenon can be seen after illuminated with UV light.3 Using the high-temperature solid-state method, Gadolinium oxysulfide phosphors doped with rare earth ions were synthesized. We can observe the red or orange phosphorescence in Gd2O2S doped with Eu3+, Sm3+, Tm3+, Yb3+, Dy3+, Er3+, Nd3+or Ho3+. This is a new result of the long afterglow phosphors research.4 Using the microwave radiation method, the new Sm3+ doped gadolinium oxysulfide phosphor, which has the orange-red long afterglow emission after illuminated with UV light or visible light, was synthesized for the first time.5 In fluorescent materials YOX doped with europium ions, the long afterglow phenomenon wasnt observed but the blue luminescence of Eu2+ and red luminescence of Eu3+ are simultaneously examined. This is a new result of the valence stability and change of Eu2+ in yttrium oxyhalide .We systematically studied the effects of the host, addition agents and reaction atmosphere on the valence change and fluorescence property of europium ions.

Papular urticaria papules urticaria more common in babies and children, most of the disease and insect bites, insect bites after the hand blisters, papules, the wind corporations, urticaria papules of the blister for the tension of blisters, often in the chest Back and limbs corporations like the wind damage, severe itching.

丘疹性荨麻疹丘疹性荨麻疹多见於婴儿及儿童，大部分发病与昆虫叮咬有关，昆虫叮咬手后出现水疱、丘疹、风团，丘疹性荨麻疹的水疱为紧张性水泡，常常在胸背和四肢有风团样损害，有剧烈瘙痒。

小鼠感染裂头蚴后，多组织器官有裂头蚴寄生，其中以皮下肌肉处多见。裂头蚴寄生可引起组织不同程度的增生、变性、坏死，组织结构破坏及大量炎症细胞浸润等病理变化。

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。

Qualitative and quantitative analysis of chemical constituents.(1) Based on the GC spectrum of 2 species, Whitmania pigra and Poecilobdella manillensis shows little difference between them. 24 kinds of fatty acid in Whitmania pigra was firstly separated and determined by GC/MS. Among them, phenylacetic acid is a component which has active of anticancer. The existence of many unsaturated fatty acid provides chemical evidence for ShuiZhi's functions of invigorate the circulation of blood.

Results 5-FU inhibits growth of Lovo cells; it is found that within a limited dosage and period of time, there has been an obvious increase in apoptosis cells under the photomechanical scope; the analysis of Lovo cells by FCM showed that after the induction of 5-FU, the percentage of apoptosis cells has increased; and FCM also displays dosage and time effects. Electrophoresis was obviously in a stripe shape of trapeziform.
