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 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 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 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.

Objective To determine the importance of aneuploidy screening in preimplantation genetic diagnosis for the couples of chromosome translocation carriers. Methods To perform 11 prenatal genetic disgnosis (PGD) cycles for 7 couples of chromosome translocation carriers from January 2006 to March 2009 in the Reproductive Medical Center, First Affiliated Hospital of Zhengzhou University. To re-analyze the well-fixed, non-multinuclear and non-debris nuclei using the probes of LSI 13, 18, 21,CEPX, CEPY to detect the aneuploidy rate which come from the PGD cycles of the couples of chromosome translocation carriers. The euploid embryo was defined as two fluorescence in situ hybridization (FISH)signals of LSI 13, 18, 21 respectively and two signals of CEPX, or one signal of CEPX and one signal of CEPY. The other abnormal signals were defined as aneuploid embryo. Results (1) A tolal of 130 nuclei from 11 PGD cycles got the integrated re-FISH signals. Nine hundred and thirty-seven FISH signals were analysized, including 304 signals from 38 euploid nuclei and the others from 92 aneuploid nuclei. (2) The number of the aneuploid nuclei from grade Ⅰ , Ⅱ and Ⅲ embryo was 20 (22%), 36(39%), and 36(39%). The number of the euploid nuclei from grade Ⅰ , Ⅱ and Ⅲ embryo was 13(34%), 17(45%),and 8(21%). There was no significant difference of aneupioidy rate between the embryos form different grades (P＞0.05). However, the rate of aneuploid nucleus from good quality embryos (grade Ⅰ + grade Ⅱ) was 60% (59/92). (3) The euploidy rate was 71.4% (30/42) from balanced embryos, while 9.1%(8/88)from unbalanced embryos. There was significant difference between them (x2=53.4, P＜0.05).The rate of aneuploidy from balanced embryos was lower than those from unbalanced embryos (P＜0.05).Conclusions Since higher rate of aneuploidy was detected in embryos of the couples of chromosome translocation carriers. It is advisable to recommend the FISH re-analysis for aneuploidy screening to preimplantation genetic diagnosis for the couples of chromosome translocation carriers.

Objective To explore the method of correctly placing and fixing mesh plug and patch in tension-free hernioplasty. Methods The data of 123 cases of plug-mesh tension-free hernioplasty with the method of placing and fixing mesh plug and patch were reviewed. Observed the incidence of postoperative effusion, infection, sinus formation, skin flap necrosis and hernia recurrence. Results All patients were restored after operation 8 days. Followed-up 1.5 -10.0 years,there was no incision effusion, infection,skin flap necrosis in all cases. No relapse happened on the operated side and 5 cases of inguinal hernia occurred on the non-operated side. Conclusions Mesh plug and patch must be placed to cover the whole abdominal wall defects,and contact closely with surrounding healthy tissue. They need to be placed neatly,fixed firmly and perpetually without any damage to the normal tissue structure.
