0.05).Conclusion Ultrasound-guided injection of APG is one of the easy,safe,and effective methods for femoral artery pseudoaneurysm.

This article discussed the ancient and modern meaning of security of intense drugs for pregnant woman. And emphatically studied the meaning of the ‘gu’, pointing out that ‘gu’had three connotations, one referred to disease, second mean the original disease, with the ‘new’disease relative, the third referred to reasons. In addition, the article expounded how can be safe for the pregnant woman to use drugs with extremely intense action. In this paper, its purpose was to examine how to achieve security under circumstance of sick and fi nally achieve balance and harmony.

Tumor cell proliferation activity is related with tumor biological behavior. PCNA (proliferating cell unclear antigen, PCNA) is a kind of histone nucleoprotein, is associated with cell proliferation and DNA synthesis,can reflect the degree of cell proliferation and cycle period, it is as a cell proliferation activity indicator, has been widely used in a variety of tumor research,the expression of PCNA in common head and neck tumor can be used as the biological behaviour and prognosis judgement.

Objective: To make it clear whether there exists m elatonin receptor in the thyroid of human embryo. Methods: Thyr oid was collected and sliced up to be stained with methods of immunohistochemis try and in situ hybridization. Results: The thyroid tissue w as p ositively dyed, melatonin receptor mt1 and MT2 were with both immunohistoche mistry and in situ hybridization while brown granules dep osited in the membrane, plasma and nuclear of the thyroid cell were with the imm unohitochemistry. Conclusion: There exists melatonin rece ptors in human embryo thyroid, either mt1 or MT2, and they exist in the memb rane, plasma and nuclear.

Objective To investigate the effect of nerve growth factor (NGF) on recuperate of optic nerve after contusion by clamping in adult rabbits. Methods Sixteen adult rabbits were randomly divided into NGF and the control group with 8 rabbits in each group. After the optic nerve of the right eyes was clamped,tissue engineering nerve containing (0.06 ml) NGF(concentration: 5?10~(-4) g/L, NGF group) and 0.06 ml of PBS (control group) was immediately transplanted into the injured eyes respectively, and 0.02 ml NGF(concentration: 5?10~(-4) g/L, NGF group)and 0.02 ml of PBS (control group) were injected into the vitreous of right eyes respectively. Flash visual evoked potential (FVEP) test was performed on the eyes 1 day, 2 weeks and 8 weeks after the injury. The number of retinal ganglion cells (RGCs) and changes of optic nerves were observed by light microscopy and electron microscopy at the 8th week after contusion,and a computer-image-analysis system was used to count the optic nerve axons. Results The ratio of amplitude of FVEP of the injured and healthy eyes was 0.765?0.150 in NGF group and 0.494?0.108 in the control at the 2th week after injury with a significant difference between the two groups (P

Objective To evaluate the effectiveness of uterine arterial embolization (UAE) in the management of uterine fibroids (UF) and adenomyoma. Methods The UAE was carried out in 22 cases of UF and 2 cases of adenomyoma, including bilateral UAE in 23 cases and unilateral UAE in 1 case, by using polyvinyl alcohol (PVA) particles as embolic materials. Results The success rate of UAE in the study was 95 8% (23/24). No serious complications occurred. The uterine and UF volume decreased remarkably in size 6 months after the treatment ( t =2 391 and 3 990, respectively; P =0 022 and 0.000, respectively). In the patient who underwent unilateral UAE, the UF gradually increased in size and a hysterectomy was required. The 2 patients with adenomyoma experienced relief with this treatment but had a recurrence 4 months after the surgery. Conclusions UAE is a safe and effective method in the management of UF but its long-term effects remains a question to be answered through further observations . The efficacy of treatment of this method for adenomyoma is not apparent.

Objective: To make it clear whether there exists melatonin receptor in the thyroid of human embryo. Methods: Thyroid was collected and sliced up to be stained with methods of immunohistochemistry and in situ hybridization. Results: The thyroid tissue was positively dyed, melatonin receptor mt 1 and MT 2 were with both immunohistochemistry and in situ hybridization while brown granules deposited in the membrane, plasma and nuclear of the thyroid cell were with the immunohitochemistry. Conclusion: There exists melatonin receptors in human embryo thyroid, either mt 1 or MT 2, and they exist in the membrane, plasma and nuclear.

0.5). However, when the flexible bronchoscope was used, foreign bodies dropped into the esophagus in 5 patients. Conclusion The characteristic manifestations was not frequent in the patients with larynx and trachea foreign bodies.History of aspiration was the most sensitive diagnostic tool. The plain chest radiography and fluoroscopy had low positive finding.Therefore, fiberoptic bronchoscopic examination should be performed timely.However, for extraction of foreign bodies, rigid bronchoscope would be the first choice.

genetic screening offered prior to preimplantation genetic diagnosis.

Objective To analyse the DNA heterogeneity of 20 clinical isolates of Acinetobacteria using infrequet-restriction-site PCR (IRS-PCR ).Methods Strain-specific electrophoretic patterns from PCR products by amplifying DNA sequences flanking infrequent restriction of 20 strains of Acinetobacter were compared with the results of genotype with RAPD as well as the results of biotyping.Results Among the 20 bacteria, ten can be recognized as Acinetobacter haemolytius with biotyping, seven as Acinetobacter lwoffi, while the other 3 bacteria can not be recognized. Acinetobacter haemolytius isolates were divided into 5 gene types with IRS-PCR, isolates of Acinetobacter lwoffi were divided into 4 gene types, meanwhile, the last three bactria were divided into 2 gene types. With RAPD technique, Acinetobacter haemolytius, Acinetobacter lwoffi and the other 3 bacteria were divided into 6 gene types, 4 types, and 2 types by prime 1, respectively, the amplifying results of primer 2 divided Acinetobacter haemolytius into 9 gene types, the Acinetobacter lwoffi ,5 types and the other 3 bacteria,2 types. Conclusion IRS-PCR can be used for typing Acinetobacter and is more aceurate than biotyping. It has the same recogniton abili ty as RAPD while is of better stability and repeatability, so this method is capable of clinical application.
