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 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 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.

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.

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.

ObjectiveTo study the relationship between osteoporosis and carotid artery disease in the elderly. Methods102 elderly patients were registered for this study and the extraeranial carotid was detected by ultrasound scan. The carotid intima-media thickness (IMT) and the plaque index (PI) were measured and calculated respectively. Meanwhile the patients were divided into two groups according to the results of bone mineral density (BMI) measurement: the osteoporosis group and the non-osteoporosis group. The IMT, PI, carotid stenotic rate and some biochemical parameters were recorded and compared between the two groups. Relationship between these parameters and osteoporosis were evaluated by logistic regression model and partial correlation analysis. ResultsThe differences in serum calcium and the levels of TC,TG,HDL and LDL between osteoporosis group and non-osteoporosis group were statistically significant (all P＜0.05), while the level differences in serum phosphorus, fasting blood glucose and uric acid had no statistical significance between the two groups (P＞0.05). Moreover, the IMT and PI in osteoporosis group were significantly higher than those in non-osteoporosis group (P＜0.05). Among the 102 patients, 48 cases showed the carotid stenotic rate ＞ 50%, including 41 patients in osteoporosis group as well as 7 patients in non-osteoporosis group(P＜0.05). Logistic regression showed that age, HDL-C, IMT, PI and carotid stenotic rate＞50 % were the correlated factors of osteoporosis and among them, IMT, PI and carotid stenotic rate＞50% had higher risks (OR = 17.13,99.33,289.13). There was positive correlation between the carotid artery disease and osteoporosis. ConclusionsThere is a relationship between osteoporosis and carotid artery disease in the elderly. Emphasis should be paid on comprehensive prevention for osteoporosis and carotid artery disease in the elderly.

BACKGROUND: Embryonic pancreatic tissue is characterized by its abundance, potent in proliferation & differentiation, and minimal immunological rejection. It is widely considered as potential pancreatic endocrinological stem cells resource for treating diabetes mellitus.OBJECTIVE: To investigate the embryonic mouse pancreatic tissue isolation technique and observe the recipients' blood glucose regulatory effects of the grafted embryonic pancreas in an experimental diabetes mellitus mouse model.METHODS: Pancreatic tissue from C57B1/6 mouse embryos at embryonic days 11.5-16.5 was isolated under the stereomicroscope. C57BL/6 mouse models of streptozocin-induced diabetes mellitus were established and then randomly divided into two groups: transplantation group, in which, five pieces of pancreatic tissue of mice at embryonic 16.5 days were transplanted into mouse renal capsule, and sham-operated control group, in which, 0.05 mL RPMI1640 culture medium was injected into mouse renal capsule. When blood glucose level of the transplantation group mouse was≤ 11.2 mmol/L, the endocrine function of embryonic pancreatic tissue transplanted was detected by IPGTT and IPITT methods and then the transplanted graft was removed for observing the blood glucose relapse.RESULTS AND CONCLUSION: Nearly intact pancreatic tissue of mice at embryonic days 11.5-16.5 could be isolated through the use of stereomicroscope. Pancreatic tissue morphology and color of mice ≤ embryonic 12.5 days were difficultly distinguished from adjacent tissue and they could only be isolated carefully according to the relationship with adjacent organs. Pancreatic tissue of mice > embryonic 12.5 days exhibited initial endocrinological tissue morphology mimic white cauliflower. Histological and ELISA examinations showed that embryonic pancreatic tissue could express and secrete insulin and the insulin level was gradually increased with developmental time. Embryonic pancreatic tissue could grow beneath the recipient renal capsule. The insulin and glucagon expression in the post-transplantational pancreatic tissue graft was increased compared with prior to transplantation. These results suggest that pancreatic tissue is a potential stem cell resource for treating the diabetes mellitus.
