Objective To investigate the therapeutic methods and curative effect of combined interven-tional therapy on hepatic metastasis from colorectal cancer. Methods Hepatic artery angiography and port-calheter-system( PCS) were undertaken in 35 cases of liver metastasis from colorectal cancers. Therapeutic measare were divided into transcatheter arterial infusion(TAl) in 10 cases and transcatheter arterial emboliza-tion(TAE) in 25 cases according to their angiographic features. Drugs included oxalic acid platinum, CPT11 , MMC and 5-Fu + CF. Laser ablation under the CT guidance was taken after 2-3 courses of treatment, including 9 cases of ethanol ablation besides laser ablation. The curative effects were determined after laser ablation by checking with CT and CEA one month later. Results The lesions shrank in 17 cases, while 13 remained the same and enlarged in other 5 after 2-3 courses of TAE or TAI. CEA reduced in 6 cases, with no change in other 5 and increas in another 3 among the 14 positive CEA cases. CT scan showed spotty gasification in 29 cases and whole gasification in 6 after additional ablation treatment. Among them, the foci dwindled in 8 cases treated by solely laser ablation, with no change in 5 and increase in 7. The foci dwindled in 5 cases, 2 remainal the same and increase in 2 of 9 cases treated by the combination of laser ablation and percutaneous ethanol injection (PEI). Among 8 unchanged or increased CEA cases after TAE or TAI, showed decrease in 3 cases, other 4 remained the same and another increased after ablation. Conclusions 1. The blood supply of hepatic metastastic foci from coloreclal cancer is mainly fed by hepatic artery and subselective transcatheter angiography showed tumor stain clearly. 2. By means of PCS and TAI or TAE, using oxalic acid platinum, CPT11 and 5-Fu regular chemical therapy provided a better curative effect for metastasis. But 3. TAI or TAE can not eliminate all foci laser combining with ethanol ablation would be the effective complement.

21 8 patients with acute pulpitis were randomly divided into 2 groups.1 09 cases were treated by Depulpin inactivation agent (group DI)for emergency management,another 1 09 cases were treated by pulp drainage with phenol camphor cotton ball(group CP).The effective analgesia rate of DI and CP group was 95.4% and 69.7% respectively(P<0.001 ).

Objective To investigate the interventional therapy for the complication in the treatment of advanced primary hepatocellular carcinoma.Methods 62 cases of primary hepatocellular carcinoma confirmed by pathology,imagings and AFP,were randomly divided into 2 groups according to odd or even hospitalization number.32 patients were enrolled in the TACE group(control group)and 30 patients were enrolled in the combination therapy group(TACE + other kinds of therapy).Patients in the combination therapy group underwent the TACE procedure adding with another kind of therapy for treating the complication such as arterial,venous,portal vein cancer embolism,or the inferior vena cava tumor embolisms and may further include ablation of residual cancer,jaundice,hepatic abscess or biloma.Results 1,2,3-years survival rates and median survival rates of the control group and combination therapy group were 68%,50%,19% and 87%,75%,48%;1.5 years and 2 years,respectively.Survival rate and duration in the combination therapy group was significantly greater than those of control group(P

Objective To investigate the effectiveness of TACE in combination with percutaneous microwave coagulation therapy(PMCT) in treatment of hepatocellular carcinoma.Methods 82 cases of hepatocellular carcinoma confirmed by pathology were randomly divided into 2 groups by odd or even hospitalization number.A total of 40 patients were enrolled in the TACE only group(group A) and 42 patients were enrolled in the synthetic therapy group(group B,underwent treatment by TACE in combination with PMCT).Results The survival rates in 1,2 and 3 years were 70%,54% and 20%,respectively,with a median survival of 1.72 years in group A,and 88%,76% and 51%,respectively,with a median survival of 2.1 years in group B.The survival rates in group B were significantly higher than that in group A(P

ObjectiveTo modify the technique of whole small bowel transplantation in rats to improve the survival.MethodsOne hundred and six SD rats served as donors and recipients to establish a homogeneous and orthotopic model of small bowel transplantation without fistula.Anastomosis of aorta and vein was done with three- cuff technique,the vena mesenterica superior of recipient was done under a surgical microscope.End-to-end anastomosis was performed between donor proximal small intestine and receptor jejunum,and also between the remote and receptor ascending colon.Surviving more than 3 days after surgery was defined as the operation was successful.ResultsThe operation was successfully carried out in 48 cases with the survival rate of 90.6％ (48/53).The average warm ischemic time was 0 minute,and the average cold ischemic time was(30 ±2.48)min.The survival rate( ＞7 d) was 97.9％ (47/48).ConclusionsOn the basis of three-cuff technique,the survival of SBT was greatly improved.When the vena mesenterica superior of recipient was done under a surgical microscope,the surgical training time was shortened.

Nogo receptor is specific inhibiting factor conjuncted with myelin of central nervous system(CNS).After spinal cord injury,oligodendroglial cell and Nogo-A released from myelin inside cells inhibited the axonal regeneration.To analyze the intervention for Nogo receptor through molecule outside cell,information inside cell and gene,make clearing the inhibiting action of myelin-associated inhibiting factor-1,provide new thoughts and methods about axonal regeneration after spinal cord injury.

Objective To study the incidence of venous thromboembolism (VTE) between complete and incomplete spinal cord injured patients. Methods 177 cases of acute cervical spinal cord injury were observed from April 2007 to July 2010. According to ASIA classification, 52 cases of grade A involved in observation group, while 125 cases of grades B~D involved in control group. Intervention included low molecular weight heparin and rehabilitation training. Incidence of VTE in two groups was compared. Results There was 11 cases complicated with VTE in the observation group (21.2%) while 6 cases in the control group (4.8%). There was a difference in incidence of VTE between two groups (P<0.05). Conclusion There is a higher incidence of VTE in complete than incomplete cervical spinal cord injury

OBJECTIVE:To summarize the clinical effect of compound glycyrrhizin(CG)on SARS.METHODS:The clin?ical data of73patients with clinically diagnosed SARS(37cases were treated by CG)were prospectively analysed.RESULTS:After CG treatment,the symptoms of dry cough,chest distress and dyspnea improved quickly and the elevated serum level of aminotransferase decreased.The maximal dosages of corticosteroids used in CG group and control group were(354.3?219.8)mg/d and(430?262.6)mg/d,respectively.The average time to occurrence of antibody,duration for reduction of corticosteroid dosage and duration of hospital stay were shorter in CG group than those in control group.There was no significant difference in titer value of antibody between two groups.CG had little effects on WBC,blood sugar and electrolytes.CONCLUSION:CG may be a promising drug against SARS with less side effect.

OBJECTIVE:To summerize the characteristics and variability of chest X-ray manifestations in SARS patients treated with compound glycyrrhizin.METHODS:60cases of SARS were equally divided into2groups:groupⅠreceiving compound glycyrrhizin,groupⅡ(as control)receiving conventional treatment.The appearing time,site,scope and dynamic changes of the pulmonary lesions on chest radiograms were compared between2groups.RESULTS:The average period from peak to50%improvement of lesion in X-ray manifestations was shorter in groupⅠthan that in groupⅡ.In restoration stage,more patients had their X-ray findings absorbed in groupⅠcompared with the patients in groupⅡ.Compound glycyrrhizin had little influence on WBC,blood sugar and electrolytes.CONCLUSION:Glycyrrhizin may be a promising drug against SARS with less side effects.
