Abstract： Objective To investigate strategies for prevention，early diagnosis，and prompt treatment for acute pulmonary embolism（PE）after video-assisted thoracoscopic surgery（VATS）lobectomy. Methods From January 2007 to November 2010, 1 115 patients with lung cancer underwent VATS lobectomy in the First Affiliated Hospital of Guangzhou Medical College. Among them, 13 patients had acute PE postoperatively, including 6 male patients and 7 female patients with their mean age of 62.3 years（ranging from 42 to 73 years）.All the patients were diagnosed by spiral CT pulmonary artery angiography（SCTPA）, and received anticoagulation therapy with low molecular weight heparin and warfarin. Results The incidence of acute PE after VATS lobectomy was 1.17%（13/1 115）, and the patients with low PE-related early mortality risk accounted for a large proportion（11/13）. There were 12 patients with right-side PE. All the patients’ signs and symptoms were significantly alleviated after administration of anticoagulation therapy. Nine patients received SCTPA review after treatment which showed that their PE had disappeared or been significantly absorbed. No hematological complications including thoracic hemorrhage or wound errhysis occurred after treatment. All surviving patients were followed up for 1 month to 3 months. During follow-up, these patients were alive without PE recurrence. Conclusion SCTPA is the first-choice examination for the diagnosis of acute PE after VATS lobectomy. Prophylaxis against PE and prompt treatment are necessary depending on individual manifestations. VATS lobectomy should be favored as a minimally invasive surgical treatment for patients with lung cancer, for the low incidence of postoperative PE and low PE-related early mortality risk.
We have performed guided chemoembolization on 84 patients of moderate and advanced carcinoma of liver using adriamycin lipiodol emulsion (A/L) since 1986. Result showed that the rate of improvement of symptoms was 86.1%, in 75% cases the AFP were decreased and in 79.2% the size of tumor were reduced. The mean survival time was 10.3 months which was much higher than that of the control group (5.6 months,Plt;0.001). THe survival rates of 1/2,1,2,3 year were 89.3%,43.4%,13.5% and 3.8% respctively that were significantly higher than those of the control group (51.2%, 11.5%,0) (Plt;0.01). Three patients underwent secondary resection after using A/L chemoembolization ans gelatin spinge central embolization with a longer survival rate. This may be a good method of treatment to the nonresectable liver cancers and may also be an easy way for postoperative observation.
OBJECTIVE To investigate the mechanism of electrothrombosis by copper needle, in order to supply the referential data for clinical treatment of vessel deformity. METHODS The mechanism and condition of thrombus formation by copper needle were studied in vivo and in vitro using electrophysics, atom absorption spectrophtometry, histological, and histochemical methods. RESULTS Great deal of copper ion was dissociated, and agglutination of red blood cells(RBC) in blood could be observed in vitro after the current applied by copper needles. Formation of stable thrombus was related to voltage and time of application of electric current. CONCLUSION Dissociation of copper ion and agglutination of RBC are the basic principle of electrothrombosis with copper needle. A 4V direct current and 17.5 minutes are the safe and effective conditions for thrombus formation in the blood vessels.
目的 探讨脾动脉栓塞治疗亲体肝移植术后脾动脉窃血所致小肝综合征的疗效。方法 我院2007年4月至2009年9月期间共完成亲体肝移植25例，其中有2例发生脾动脉窃血致小肝综合征，均采用介入技术经皮行脾动脉栓塞治疗。结果 行脾动脉栓塞术后，2例患者腹水逐渐减少，转氨酶水平、血小板及白蛋白水平及肝功能较快恢复正常。栓塞术后1个月复查，肝功能仍基本正常。结论 脾动脉栓塞是治疗肝移植术后脾动脉窃血所致小肝综合征的有效措施。

Objective To evaluate the safety and effectiveness of interventional therapy for hyperthyroidism. Methods From 1995 to 2000, 38 cases underwent bilateral super-selective superior thyroid arteries embolization with brown-algae microballs.Results There was no misembolization and mortality. Hyperthyroidism crisis developed in 2 cases. Thirty eight cases were followed-up for 0.5～5 years (the median time was 2.2 years). Medications were needed only in one patient because of relapse and the others were cured. Conclusion This procedure features miniinvasive trauma, less complications and quick recovery. It may be a safe and rational treatment for hyperthyroidism.
【Abstract】ObjectiveTo study the effect of preoperative gastric arterial chemoembolization on apoptosis of lymph node metastasis of gastric cancer. MethodsForty patients with gastric cancer and lymph node metastasis underwent curative resection, among which there were 20 patients who received the preoperative gastric arterial chemoembolization, and they constituted the treatment group. The rest of the patients were included in the control group. The expressions of p53, CD95 and bcl-2 were examined by immunohistochemistry and apoptosis in the lymph node metastasis was examined by in situ terminal transferasemediated dUTP nick end labeling （TUNEL）. ResultsThe expression intensity of p53 and CD95 in lymph node metastasis of treatment group increased more significantly than that of control group, whereas the expression intensity of bcl-2 decreased in treatment group. There was a significantly positive correlation between the expressions of p53 and CD95 and the apoptosis.ConclusionPreoperative gastric arterial chemoembolization may affect the expressions of p53, CD95 and bcl-2 and may induce the apoptosis of lymph node metastasis. It may be helpful to improve the effect of curative resection of gastric cancer.
Objective To evaluate the efficacy of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in treating primary hepatocellular carcinoma (HCC). Methods From March 2004 to March 2006, 137 patients with primary HCC underwent TACE alone (n=87) and TACE+RFA (n=50), respectively, after the interventional treatment, all patients periodically received CT reexaminations and alpha fetoprotein (AFP) measurement. The therapeutic efficacy, AFP level and survival rate between two groups were compared with each other. Results In TACE group the effective rate (CR+PR) was 34.5%, AFP decreasing amplitude was 54.2%, and 2 years survival rate was 43.7%. While in TACE+RFA group, the effective rate (CR+PR) was 70.0%, AFP decreasing amplitude was 78.0%, and 2 years survival rate was 62.0%, there were significant differences between two groups (P＜0.05). Conclusion Combined application of TACE and RFA is significantly superior to TACE alone in treatment of primary HCC.
