The pattern of the seismic sequence by vibrational liquefaction provides one of correlation standards for geologists in the field to discriminate events in carbonate sequences. Based on the pattern of seismic sequence, the authors first advance a new conception of the Palaeo-Tanlu (Tancheng-Lujiang) Zone and discuss primarily its geological significations.展开更多

The distributions of them represent paleo-seismic tectonic zones in different periods, which is tallied with convergent continental block before Proterozoic supercontinental Rodinia and the evidence of the breakup or splitting developed in the inner Sino-Korean Platform in 700 Ma.展开更多

METHODS A total of 50 cases of nonresectable primary hepatocellular carcinoma underwent segmental transcatheter arterial embolization. Two methods of superselective segmental catheterization were used, one was the method of wire guiding, and the other the technic of co axial infusion catheter. RESULTS The 1 , 2 , 3 and 4 year cumulative survival rates of 50 cases with segmental transcatheter arterial embolization for primary hepatocellular carcinoma were 83 8%, 65 4%, 42 9% and 24 5% respectively. The incidence of the lipiodol overflow into portal veins was 64%. The overflow of lipiodol into portal veins, represented as 3-5 grade branches of portal veins visualized by lipiodol, was “star like” or “tree like”, and there was a relatively large vessel in the center surrounded with radicalized small branches of vessels. CONCLUSION The lipiodol overflow into portal veins was one of the signs of complete embolization for tumors, and may play a partial role in embolizating the portal venous supply for hepatocellular carcinoma.展开更多

Subfascial endoscopic perforator surgery （SEPS） plus endovenous laser treatment （EVLT） could be applied as individual therapy. This study aimed to evaluate the feasibility of performing combined SEPS and EVLT without impacting GSV in the management of valvular insufficiency of the lower-limb venous perforators. Methods Placement of lower-limb venous perforator insufficiency was marked by ascending phlebography in 83 affected limbs from September 2010 to June 2011. After randomization, SEPS was performed on 41 limbs to address the insufficiency of the venous perforators under the deep fascia, in combination with EVLT to close the superficial varicose veins without impacting the GSV. The remaining 42 limbs were treated using traditional GSV phlebectomy as controls. Results Postoperatively, all varicose veins were resolved, with lightening of the pigmentation and healing of the ulcer. Within a follow-up period of 5-11 months, no symptoms had recurred. Compared with the control group, the operation time, the number of incisions sutured, and the in-hospital time decreased on average by 1.5 hours, 4.7, and 6.8 days, respectively （P 〈0.01 in all cases）. Conclusion Combined SEPS and EVLT for treatment of valvular insufficiency of the lower-limb venous perforators offer the advantages of microtrauma and rapid cure.展开更多

Several large-scale studies of surgery or intervention strategies for treating BCS have been reported. However, much controversy still remains regarding many aspects of this disease, including its etiology, treatment, and classification. This review explores these controversies with emphasis on areas that merit further study.展开更多
