Objective Aim To investigate the effects of high-burden thrombus on outcomes of emergency percutaneous coronary intervention(PCI)in elderly patients with acute myocardial infarction.Methods Seventy-three elderly patients with ST elevated acute myocardial infarction(STEAMI)within 12 hours from onset received emergency PCI.They were divided into the high-burdern thrombus group(n=26)and the low-burden thrombus group(n=47)according to coronary artery angiography result.Mortality of 30 days,peak value of CK-MB,ejection fraction(EF)and TIMI flow after PCI were compared.Results The occurance of high-burden thrombus in infarct-related arteries was 35.6% which was more often common in right coronary artery.The rate of TIMI3 flow after PCI in high-burden thrombus group was lower than that of the low-burdn thrombus group.The 30-day-mortality and peak CM-MB level in the high-burden thrombus group was higher than that of the low-burden thrombus group.Conclusion High burden thrombus is an important factor of prognosis in elderly patients with acute myocardial infarction after emergency PCI.

AIM: To explore the effect and mechanism of preoperative transarterial chemoembolization on nephroblastoma.METHODS: Comparative analysis of clinical and pathological features in 39 children with Wilms’ tumor was conducted. TUNEL assay was used to detect the apoptosis of tumor in two groups with or without preoperative interventional treatment. The expressions of P53, Bcl-2 and Bax proteins were detected by immunochemical methods. The patients were followed-up for more than 2 years.RESULTS: The extent of neoplastic cell necrosis and degeneration, interstital fiber tissue hyperplasia of tumor and the number of infiltrating lymphocytes were observed, which were higher in interventional group than those in simple excision group (P

How to remove the well fixed cement or cementless prosthesis and get a completely distal cement removal in the rTHR are critical to the outcome of revision. Because of higher rate of union, excellent intraoperative exposure, and adjustment of abductor tension, ETO has been widely applied to rTHR and complicated primary THR by foreign scholars. Furthermore, this technology has wide indications, very few contraindications, high cure rates,and low complications rate. ETO turns out to be a safe and effective revision technology. In the article, the indication, contraindication, complications and advantages of this technique were reviewed.

Objective To study the clinical value of mammography and ultrasound needle localization biopsy technique in clinical nonpalpable breast disease.Methods 148 patients with negative clinical palpation were operated only because of the mammography or ultrasound findings of lesions.They were undergone localized excision biopsy and derived definite pathological diagnosis.By histopathology diagnosis,benign and malignant lesions,lesion size,complete resection rate were statistically analyzed.Results 21 cases in 148 cases were malignant lesions(14.2％),which were all early breast cancer.The other 127 cases were benign breast disease(85.8％).147 cases were successfully resected at the first time and 1 case was successfully resected at the second time.Conclusion Mammography and Ultrasound fine needle localized biopsy in nonpalpable breast disease diagnosis and treatment has great significance,which can raise early diagnosis rate of breast cancer without mass,and this method is simple and easy for promotion.

Objective To study the diagnostic and treatment value of wire guided localization of breast biopsy for non-palpable breast lesions.Methods The clinical data of 314 cases of non-palpable breast lesion resection operation in our hospital were retrospectively analyzed.The accuracy rate of resection and postoperative pathological examination results were analyzed.Results All lesions were positioned accurately and completely resected,48 cases in 314 cases were breast cancer(15.3 ％),in which 42 cases were early breast cancer which were confirmed by pathology (87.5％).Conclusion Wire guided localization of breast biopsy has high accuracy,low cost,which is useful for the diagnosis of early breast cancer,there is a certain value in clinical application.

Objective To investigate surgical opportunity and suitable treatment approach in nodular Hashimoto's disease.Methods An analysis was performed in 388 pathologically confirmed cases with nodular Hashimoto's disease and other thyroid-related diseases.All the cases were involved with surgical treatment due to thyroid nodules from June,1995 to Dec,2005.Results Among the above-mentioned cases,64 cases (16.5%) were Hashimoto's disease with the presence of thyroid cancer,190 (48.9%) nodular thyroid tumor,94 (24.2%) thyroid adenoma,7 (1.8%) hyperthyroidism,the rest (8.5%) simple Hashimoto's disease.Prior to 2000, among 106 cases of Hashimoto's disease there were 15 cases accompanied by thyroid cancer.Since 2001,282 cases of Hashimoto's disease were dealt surgically,49 of which had thyroid cancer.Compared to the period from 1995 to 2000,the complication of Hashimoto's disease and thyroid cancer has been sharply increasing during the recent five years (P

Background Researches demonstrated that ciliary neurotrophic factor (CNTF) can enhance survival and promote differentiation of neutron.Meanwhile,CNTF also is thought to play an important role in the development of visual pathway.But,less studies are reported in the relationship of CNTF and form deprivation amblyopia.Objective This study was to investigate the expressions of CNTF in visual cortex area 17 in form deprivation amblyopia model.Methods Twelve 4-week-old cats were randomized into normal group and form deprivation amblyopia group.Monocular form deprivation amblyopic models were established in 6 cats by eyelids suture method.Pattern visual evoked potential(P-VEP) was recorded to evaluate the amblyopic models 16 weeks later following the eyelids suturing.Then,bilateral visual cortex tissue was incised at a vertical in sagittal axis fashion to prepare the section.Nissl staining was used to detect the morphologies of neurons.Expression of CNTF in Ⅰ-Ⅵ layers of visual cortex area 17 was located and quantified by immunochemistry.The positive cell number and gray scale for CNTF were calculated and compared between two groups.The use of the animals complied with Regulations for the Administration of Affairs Coucerning Experimental Animals by State Science and Technology Commission.Results Compared with the normal group,P-VEP amplitude was significantly reduced (6.11 ±1.56 μV vs.11.42±t.92 μV) and latency was significantly prolonged(75.77±9.83 ms vs.58.56±7.17 ms) in the form deprivation amblyopia group (t=5.272,3.464,P＜0.05).Nissl staining showed that the number of neurons in the form deprivation amblyopia group was less than that in the normal group.In the form deprivation amblyopia group,neurons became shrinkage and turned round,cytoplasmic processes get shortened,and the nucleus became small.The number of Nissl bodies was decreased.lmmunochemistry showed the positive neutrons for CNTF in Ⅰ-Ⅵ layers of visual cortex area 17 in hoth normal cats and model cats with the more positive cells in Ⅱ-Ⅳ layers.Compared with the normal group,the positive cell number for CNTF was significantly reduced in Ⅱ-Ⅳ layers of visual cortex area 17 in the form deprivation amblyopia group (Ⅱ layer:95.93±8.24 vs.116.25±6.52;I layer:102.65±7.45 vs.125.23±8.21;Ⅳ layer:l10.65±6.85 vs.139.54±4.26) (t=4.737,4.989,8.773,P＜0.05).In addition,the gray scale of CNTF positive cells was significantly lower in Ⅱ-Ⅳ layers of visual cortex area 17 in the form deprivation amblyopia group than that the normal group (Ⅱ layer:106.98 ± 8.86 vs.138.65 ± 6.38 ; Ⅲ layer:109.56 ± 8.69 vs.149.59 ±8.55;Ⅳ layer:l16.65 ±9.52 vs.155.76±9.87) (t=7.105,8.043,6.986,P＜0.05).Both CNTF positive cell number and gray scale in Ⅰ,Ⅴ,Ⅵ layers of visual cortex area 17 had no significant differences between two groups (P＞0.05).Conclusions Form deprivation in critical period of a new born animal may lead to distributing abnormality of CNTF in visual cortex,which maybe play a role in the development of form deprived amblyopia.
