Objective To compare the effect and survival period of endoscopic treatment group and non endoscopic treatment group of esophageal gastric varices bleeding in patients with hepatocellular carcinoma and portal vein tumor thrombus, in order to define the significance of endoscopic therapy for prolonging the survival period of patients. Methods 76 patients diagnosed as esophageal gastric varices bleeding with hepatocellular carcinoma and portal vein tumor thrombus from Jan. 2013 to Dec. 2015 were enrolled, of all these cases, 27 were non endoscopic treatment group and 49 were endoscopic treatment group. The medical records were analyzed retrospectively. Then compare the effect of emergency treatment, the main causes of death and survival time of the two groups. Results In the non endoscopic treatment group, 40.7% (11/27) patients died in one week after bleeding, 81.5% (22/27) patients died of esophageal gastric varices bleeding, the mean survival period was (42.03 ± 13.94) days; In the endoscopic treatment group, only 16.3% (8/49) patients died in one week (P < 0.05), 55.1% (27/49) patients died of esophageal gastric varices bleeding (P < 0.05), the mean survival time was (174.24 ± 34.42) days (P < 0.05). Conclusions Endoscopic therapy can effectively reduce the risk of death from acute hemorrhage and prolong the survival time in patients with hepatocellular carcinoma and portal vein tumor thrombus.

Prostate cancer is one of the common malignant tumors of the urinary system and mostly found in elderly men. Like most tumors, prostate cancer involves a variety of molecules in its occurrence and progression. More studies on the development of prostate cancer focus on the tumor markers, DNA damage repair related genes, and tumor invasion and metastasis related factors. This article presents an overview on the research progress in these three aspects.

Objective To report an improved method, color-ultrasonography-guided inferior vena cava (IVC) filter placement, for preventing the pulmonary embolism (PE) caused by the deep venous thrombosis (DVT). Methods Color-ultrasonography-guided IVC filter insertion was performed in 9 patients with DVT of lower limb, 1 of which also had PE accompanied with at the time of admission. Out of the 9 patients, 5 patients underwent embolectomy immediately after the filter placement while the other 4 patients were treated conservatively. Results The placements were all completed successfully. Follow-up observations for 1～7 months (mean 2 months) found no complications or occurrence of PE. No recurrence of PE was found in the patient already with PE. Conclusions The color-ultrasonography-guided IVC filter placement can effectively prevent PE caused by DVT. The method is suitable for severe, immovable patients, as well as patients with renal insufficiency and being allergic to intravenous contrast, and is safe, convenient, cheap and prone to popularization.

Objective To assess long-term outcomes of electrocoagulation for treating varicose veins of the lower extremities. Methods A retrospective review was made on clinical data of 426 cases of varicose veins of the lower extremities treatd by electrocoagulation from October 1996 to October 2001.Postoperative follow-ups were carried out with clinic checkups or questionnaires.Results Of the 426 cases,follow-ups for 4~9 years(mean,5.8 years) were completed in 364 cases(500 limbs) and a loss to follow-up was encountered in 62 cases,the follow-up rate being 85.4%.The cumulative rate of recurrent varicose veins was 10.4%(52/500),in which the recurrent varicose veins were cured with sclerosing agents in 50 limbs and with re-operations in 2 limbs.The relief rate of sensation of heaviness and tension was 95.1%(309/325).Accompanying venous ulcers in 20 limbs healed up within 2~8 weeks.The incidences of subcutaneous hematoma and saphenous nerve injury were 0.8%(5/594) and 1.2%((7/594),) respectively.Skin burns happened in 5 limbs(0.8%,5/594). Conclusions Electrocoagulation for varicose veins of the lower extremities is proved to be a novel minimally invasive method,with advantages of safety,effectiveness,low costs,and short hospital stay.

Objective To compare electrocoagulation effects of three types of electrodes for varicose veins.Methods Twelve dogs(24 veins in hind limbs)were randomly divided into 3 groups with 4 dogs in each group:columnar electrode group,circular electrode group,and radial electrode group.Each dog's long saphenous veins were high ligated and electrocoagulated.The activated partial thromboplastin time(APTT)was measured and pathological examinations(HE and Weigert)were performed immediately following operation and on the 7th and the 14th postoperative day,respectively.The destruction depth and extent,residual vessels,and skin burn after electrocoagulation were compared among the three groups.Results One case of skin burn on the left hind limb occurred in the columnar electrode group.Immediately following the operation,the number of vessels that were destroyed beyond 50% of perimeter in the radial electrode group was 8,which was significantly higher than that in the columnar electrode group(3 vessels)and the circular electrode group(4 vessels)(Fisher's exact test,P=0.013 and 0.038),and the number of vessels that were destroyed deep to the meddle membrane in the radial electrode group was 1,which was significantly lower than that in the columnar electrode group(7 vessels)and the circular electrode group(6 vessels)(Fisher's exact test,P=0.005 and 0.020).On the 7th day after operation,there was no statistical difference among the 3 groups in the number of vessels with remnant area above 50% of the perimeter(?2=5.371,P=0.068).On the 14th day after operation,the number of vessels with remnant area above 50% of the perimeter in the radial electrode group(1 vessel)was significantly lower than that in the columnar electrode group(7 vessels)and the circular electrode group(6 vessels)(Fisher's exact test,P=0.005 and 0.020).There was no statistical difference among 3 groups in APTT immediately following operation and on the 7th and the 14th postoperative day(P=0.905,0.871,and 0.865).Conclusions Compared with the other two catheters,radial electrode has the largest destroyed area,the smallest remnant area of the vessel,and the lowest risk of skin burn.
