Objective To improve the ultrasonic differential diagnosis of thyroid lump through analyzing pathological and ultrasonic features of papillary thyroid carcinoma. Methods Records of 173 cases papillary thyroid carcinoma were analyzed retrospectively in terms of preoperative ultrasonic manifestation, lesion size, echo,boundary, calcification, blood supply, lymph node metastasis and accompanying diseases etc. Results The avthe 173 papillary thyroid carcinoma cases, the number of cancer nodule was 203. There was no statistical difference between papillary thyroid carcinoma lesion and papillary thyroid microcarcinoma lesion in terms of low echo and ill-defined borders (P ＞ 0. 05). The former is higher than the latter in blood flow speed, microcalcification rate, and preoperative ultrasonic diagnosis rate (P ＜0. 01, P ＜0. 05, P ＜0. 01 respectively). The mulifocality rate for the 173 cases with papillary thyroid carcinoma is 33.53% (58/173). There was no statistical difference between papillary thyroid carcinoma and papillary thyroid microcarcinoma in cancer lesion(P ＞0. 05), while the former has a higher rate of lymph node metastasis than the latter(P ＜0. 01). Preoperative diagnosis rate is higher in papillary thyroid microcarcinoma cases without other thyroid diseases than in cases with other thyroid diseases (P ＜ 0. 05). No statistical difference of preoperative diagnosis rate was seen between papillary thyroid carcinoma patients with other thyroid diseases and those without other thyroid diseases (P ＞ 0. 05). Conclusions The overall evaluation of thyroid nodule diameter, boundary, echo, small calcification, lymph node metastasis, blood supply, accompanying diseases and so on can improve diagnosis of primary papillary thyroid carcinoma.

Objective:To study the dynamic changes and clinical singniticance of interleukin 6(IL 6) and interleukin 8(IL 8) in serum of patients with acute myocardial infarction(AMI).Methods:Asynchronous serum IL 6 and IL 8 concentrations measured with radioimmunological assay in 30 patients with AMI from symptoms onset to thromblytic therapy finished and the datas were compard with 20 members of a healthy controlgroup,to investigate the relationship between the changes and myocardial ischemia/reperfusion.Results:The serum concentrations of IL 6 and IL 8 were elevated in all patients with AMI when compared with the healthy control group ( P

Objective To summarize our experience on the treatment for severe vascular injuries in the operation of great saphenous varicose vein. Methods The clinical data of 4 cases (5 lower limbs) from December 2004 to April 2009 of severe vascular injuries were retrospectively analyzed. For the lower limbs in which from the end of femoral artery to the upper part of posterior tibial artery were stripped, reconstruction operation using blood vessel prothesis was performed, above knee amputation was performed because of limb gangrene. For three limbs in which 10 cm to 15 cm superficial femoral artery were stripped, reconstruction operation using autologous saphenous vein were performed, above knee amputation was performed for one limb 5 days after the operation. For the limb in which 2 cm superficial femoral vein were cut, reconstruction operation using autologous saphenous vein were performed. Results No cases died perioperatively,for four limbs of injuried artery, ampution were performed for two limbs(50% ) ;two limbs (50%) were saved. The patient of injuried superficial femoral vein recovered. Conclusions Severe vascular injuries can be prevented and its incidence reduced by improving the awareness for iatrogenic vascular injuries,accurate operation; once the vascular injury occurred, prompt and rational measures must be adopted.

Objective To study the role of cover-stent and embolization in the treatment of hepatic artery pseudoaneurysm following liver transplantation.Methods 5 patients with hepatic artery pseudoaneurysm after liver transplantation were treated with cover-stent and embolization between May 2010 and July 2013.The clinical features,imaging findings and complications were reviewed.Results All the 5 patients with hepatic artery pseudoaneurysm were successfully treated.2 patients with intrahepatic pseudoaneurysm received embolization.Of the 3 patients with extrahepatic pseudoaneurysm,2 received cover-stent treatment,and 1 patient received embolization.No complications related to the interventional treatment were encountered.2 patients died from multi-organ failure one month after the interventional treatment.Conclusion Cover-stent and embolization were effective and safe to treat patients with hepatic artery pseudoneurysm following liver transplantations.

Objective To investigate the clinical characteristics,diagnosis and treatment for Graves' disease associated with papillary thyroid microcarcinoma(PTMC) by retrospectively analyzing domestic and foreign literatures.Methods 32 patients of Graves' disease associated with PTMC treated at the Department of Thyroid Surgery,the First Bethune Hospital of Jilin University from Jun.2008 to Jun.2013 were collected.32 cases of PTMC with normal thyroid function were randomly selected by a random number table method from the same period as control.Results The experimental group had 32 patients aging from 24 to 71 years old,among whom 3 were males,and 29 were females with the male to female ratio was 1∶9.7.15 cases in the experimental group had positive central lymph node metastasis and the other 17 cases were negative,while in the control group 7 cases were positive and 25 cases were negative.The mean number of positive lymph nodes was 3 ± 2.88 in the experimental group and 1.71 ± 1.25 in the control group.The ratio of positive lymph node metastasis(the number of positive lymph nodes/the total number of lymph nodes,and the total number of central lymph nodes was ＞3)was (50.34 ±27.09) ％ in the experimental group and(33.5 ±30.79)％ in the control group.For the above 3 values of central lymph node metastasis,the experimental group were all higher than those of the control group (P =0.035,0.039,0.018 respectively).Conclusions Compared with patients of PTMC,patients of Graves' disease associated with PTMC are more likely to have central lymph node metastasis,more number of positive lymph node and higher metastasis ratio.In order to prevent the postoperative recurrence of Graves' disease and thyroid carcinoma local lymph node,total thyroidectomy plus central lymph node dissection should be the ideal operation method.

Secondary hyperparathyroidism is the most common complication of patients with chronic kidney disease.For patients poorly responding to medical treatment,parathyroidectomy would be the best choice.This article reviews the indications and modalities of surgical treatment for secondary hyperparathyroidism in patients with chronic kidney disease.

Objective To understand the subjective perception and influential factors of critical care training in rescue nurses. Methods The same self-designed questionnaire with a total of 49 closing entries were used before and after training course to investigate the ability of critical care and prevention ability of infectious diseases in rescue nurses. Results The ability of emergency response nursing improved remarkably after rescue nurse training (t=-7.071--3.693,P<0.01). But there were several weaknesses still in existence including specialty knowledge, first aid techniques, and clinical application of biochemical indicators, psychological trauma assessment, epidemics and ECG recognition, critical
thinking, the differences were statistically significant (t=-6.736--3.286,P<0.01). Conclusions Rescue nurses training can improve the ability to take care of critical illness under emergency situations, which can ease the insufficiency of human resource for short-term.

Leucine zipper tumor suppressor 2 (LZTS2) is a novel tumor suppressor gene that has been increasingly recognized in recent years. Currently, many studies illustrate that LZTS2 gene, the important candidate tumor suppressor gene, is already involved in the inhibition of tumorigenesis and aberrant proliferation of tumor cells, and other functions of tumor cells. Information from these stud-ies can contribute to the formulation of new strategies for the treatment of tumors.
