Objective To evaluate the method and result of thyroid artery embolization as a new therapy for hyperthyroidism. Methods Twenty two patients with hyperthyroidism underwent selective thyroid artery embolization. Totally 52 thyroid arteries were embolized with microspheres. The indications to this therapy were following: hyperthyroid patients having indications to surgical and 131 I therapy, clinically being difficult to complete the preparation for subtotal thyroidectomy and having high risk for surgical process because of their huge thyroid gland. Results Serum level of thyroid hormones dropped significantly [median T3 from 8 8 nmol/L(4 3~ 43 0 nmol/L) to 4 0 nmol/L(1 1~9 2 nmol/L), median T4 from 206 4 nmol/L(77 4~748 2 nmol/L) to 144 5 nmol/L(25 8~279 9 nmol/L), P
3.Retrospective Analysis of 17 Family Homicide Cases.
Journal of Forensic Medicine 2016;32(6):431-433
OBJECTIVES:
To summarize the characteristics of family homicide cases and to provide reference for the analysis and prevention of such cases.
METHODS:
Seventeen solved family homicide cases in Liyang from 2004 to 2014 were investigated. The original registration information, record of scene investigation, corpse inspection report and case situation were analyzed statistically.
RESULTS:
The characteristics of the 17 family homicides cases showed that most victims were female and most suspects were male, and spouse infidelity and suspected spouse infidelity have higher proportion in the motives for the killings. Murders by patients with psychosis, camouflage murders and murder-suicides occupied a certain proportion in the family homicide cases.
CONCLUSIONS
The family homicide cases are correlated with the family factors such as extramarital sexual intercourse and murder by patients with psychosis. Some suspects suicided after murder. The tools for committing crimes have the features of simplicity, randomness and easy source availability.

Objective To investigate the value of percutaneous transsplenic varices embolization (PTSVE) for treatment of upper gastrointestinal bleeding. Methods Twenty cases with liver cirrhosis and portal hypertension suffered upper gastrointestinal bleeding. PTSVE was administered to them with hardener and coils. Among them, 8 cases had massive hepatocellular carcinoma (HCC) in right lobe; 10 cases with hepatocellular carcinoma had portal vein tumor thrombus and occlusion; the other two cases with liver cirrhosis had portal vein thrombosis. All of these cases were not suitable for percutaneous transhepatic varices embolization (PTHVE) . PTSVE was performed under the guidance of fluoroscopy. Results Technical success was achieved in 18 patients. A total of 35 gastric coronary veins were embolized. In all these cases, upper gastrointestinal bleeding stopped after PTSVE. There was no recurrence within 1 month follow-up. No serious complication occurred. Conclusion PTSVE is a safe and efficient alternative treatment for upper gastrointestinal bleeding, especially for cases with portal vein occlusion or with massive HCC in right lobe of liver.

The lumber ligaments play an important role in spinal bsomechanics. The results of three-dimensional finite element analysis showed that one of functions of lumbar ligaments is transmission of the tensile load between the lumbar vertebrae. The anterior longitudinal ligament is loaded in extension of lumbar spine and the resistance to the tensile load in flexion is provided by other ligaments. These ligaments are subject to much more tension with degsneration of the intervertebral disc so that a series of pathological changes occur. Relevant significance in clinical aspect is also discussed.

Objective To evaluate interventional techniques for the treatment of visceral aneurysms. Methods A total of 11 aneurysms were found in 9 patients with visceral aneurysms who received interventional treatment. Of the 9 patients, single aneurysm at both superior mesenteric artery (SMA) and right colonic artery was seen in one, 2 aneurysms at same splenic artery in one, one aneurysm at splenic artery in 5, aneurysm at right gastric artery in one and pseudoaneurysm at hepatic artery in one. In 9 patients the transcatheter endovascular coil embolization was successfully carried out for 10 aneurysms, including splenic (n = 7), right colonic artery (n = 1), right gastric artery (n = 1) and hepatic pseudoaneurysm (n = 1). One stent-graft was used for the SMA aneurysm. Results Technical success was achieved in all cases without any serious complications. Conclusion Interventional embolization with coils can successfully occlude most visceral aneurysms, while stent-graft should be used when the aneurysm is difficult to be occluded with coil.
