Objecitve To observe the effects of ursolicacid on contractile activity of uterine smooth muscle strips of virginal rats.Methods 20 Wistar virginal rats,weight 200-300g were selected,to record the effects of ursolicacid(1.0?10~(-8),2.0?10~(-8),3.0?10~(-8),4.0?10~(-8)g/L) on contractile activity of uterine smooth muscle strips with Biolap 410 Biological System.Diphenhydramine(2?10~(-6)mol/L),Phentolamine(2?10~(-6)mol/L),Verapamil(2?10~(-7)mol/L),Indomethacin(2?10~(-5)mol/L) were used as antagonists to study the mechanisms of ursolicacid on uterine smooth muscle strips.Results Ursolicacid could significantly potentiate uterine contractile activity of virginal rats.It could increase the frequencies,prolong the duration and enlarge the amplitude of contractile activity.The effect of which could be inhibited by the Indomethacin;but could not restrained by other antagonists.Conclusion The results of Ursolicacid may be mainly primarily with prostaglandin synthese or release,but not mediated by H_(1) receptor,? receptor and L-voltage-dependant calcium channels.

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

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.

ObjectiveTo explore the methods and effectiveness of interventional revascularization of complex arteriosclerosis obliterans (ASO)of lower extremity arteries according to their imaging characteristics.Methods Seventy-eight patients with lower extremity ASO complex lesions classified as TASC Ⅱ C/D ( n =68 ) and TASC Ⅱ B ( n =10) underwent antigrade or combined antigrade-retrograde subintimal angioplasty.Their clinical situations were Fontaine stage Ⅲ/Ⅳ or severe stage Ⅱ.All the long occlusion,flush occlusion,multiple occlusion,popliteal artery occlusion,below knee artery occlusion and aortoiliac artery occlusion were identified as complex lesion imaging features and as the indication of interventional treatment if only there were visible outflow vessels and suitable puncture site.Statistical analysis was used to compare ankle-brachial index (ABI) pretreatment and post-treatment by t test.Results Successful revascularization was achieved in 73 patients technically.No obvious complications occurred.Ischemia symptoms improved quickly after accomplishment of recanalization.Average ABI increased from 0.45 ±0.07 to 0.76 ±0.11 after the treatment(t =- 19.78,P ＜0.01 ).Symptoms in 5 patients who failed to get arterial recanalization were stable.Follow up of 6 to 12 months in 47 patients showed stable improvement in 22 of them.Conclusion It is more practical to choose and expand application of interventional treatment for complex ASO according to imaging characteristics of lesions than according to TASC classification.

Objective To know the remote quality of life of patients with tumor of larynx when ab-scised by different type, and then summarize proper countermeasures of nursing. Methods Selected 82 laryngocarcinoma patients with exacte]y diagnosis. There were 40 cases had received total laryngectumy, 42 cases had received partial laryngectomy. Evaluated the level of remote quality of life of 82 patients by QLQ-H&N65, and then analyzed the datum. Results The level of quality of life of patients with total laryn-gectomy were worse than those in patients with partial laryngectomy in the aspects such as general health, swallow, language, emotional function, social function, body fuction and so on. Conclusions The quality of life of patients with tumor of larynx is influenced by several factors, their remote quality of life should be emphasised by nurses.

Objective To study the effects of nutgrass galingale rhizome decotion on contractile activity of uterine smooth muscle strips of non-pregnant rats.Methods We selected 60 Wistar non-pregnant rats of weight 250-300 g to record the effects of nutgrass galingale rhizome decotion(1.0 g/L,2.0 g/L,4.0 g/L,8.0 g/L) on contractile activity of uterine smooth muscle strips of non-pregnant rats with Biolap 410 Biological System.Four antagonists,diphenhydramine(2?10-6mol/L),phentolamine(2?10-6mol/L), verapamil(2?10-7mol/L),and indomethacin(2?10-5mol/L) were used to study their mechanisms respectively.Results Water extract of nutgrass galingale rhizome(4?10-3kg/L) could significantly weaken uterine contractile activity of non-pregnant rats,lessen the frequencies,shorten the duration and lower the amplitude of contractile activity.Conclusion The effect of nutgrass galingale rhizome on contractile activity of uterine smooth muscle strips in rats may be mainly associated with prostaglandin synthese or release nothing with L-voltage-dependant calcium channels,H1 receptor or ? receptor.

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 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.

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.

Objective To explore the feasibility and proper technique of subintimal racanalization in treating chronic aorto-iliac artery occlusion. Methods Subintimal racanalization via right brachial artery access was performed in a 57-years-old man with chronic total occlusion of aorto-iliac artery. Subintimal pathways were created with two hydrophilic guidwires (Teromo), which were inserted into the subintimal space from the occluded end of the abdominal aorta and got into the right and left external iliac arteries separately. Subintimal arterial flossing with antegrade-retrograde intervention was employed in left side to overcome the difficulty in reentering the true lumen. The exchange guidwires were conducted out of the femoral artery puncture sites on both sides in sequence, in this way the bilateral femoral pathways were established. Aorto-iliac artery balloon angioplasty and retrograde stent implantation, including one aortal and 5 iliac stents, were carried out by kissing technique from the femoral site. Results The aorto-iliac artery lumen was successfully reopened after the procedure. The internal lumen shape of the stents was satisfactory and the blood flow was unobstructed. The ischemic symptoms of the lower extremities disappeared completely. The ankle brachial index (ABI) rose from 0.32 to 0.96, and the condition remained stable in a follow-up period of 10 months. Conclusion Subintimal racanalization therapy is practical and safe for treating total aorto-iliac artery occlusion, especially for the patients with chronic arterial sclerosis.
