ABSTRACT
Hepatocellular carcinoma (HCC)originating from the caudate lobe is a special-site HCC,which is rare and difficult to treat. The major therapeutic method in the past was surgical resection.In recent years,interventional treatment for HCC originating from the cau-date lobe has achieved significant progress,and good therapeutic effect has been obtained.This paper briefly introduces the anatomic fea-tures of the caudate lobe and the features of blood supply in HCC originating from the caudate lobe,reviews the research advances in the therapeutic methods of transcatheter arterial chemoembolization and local ablation for HCC originating from the caudate lobe,and points out that a combination of interventional therapies for HCC originating from the caudate lobe needs to be further investigated in clinical practice.
ABSTRACT
Objective To investigate clinical efficacy about treatment of trigeminal neuralgia using botulinum toxin of type A and ultrashort wave.Methods 40 patients with trigeminal neuralgia were randomly divided into the control group(n =20)and the treatment group(n =20)according to digital table method,patients in the control group were injected with lidocaine,triamcinolone acetonide and vitamins B12 injection in pain -sensitive point,the treatment group were injected botulinum toxin of type A 50 -150 u in pain -sensitive point.The two groups were in the ultrashort wave therapy.Used VAS pain scores to evaluate local pain about two groups of patients before treatment,one week after treatment,one month after treatment,three months after treatment,the clinical efficacy after treatment at different time points were compared between the two groups.The two groups of patients showed sleep improvement,the sleep status of patients were observed.Results The VAS score in the control group 1 week after treatment was (3.78 ± 1.35)poinrs,and was (7.03 ±1.07)poinrs before treatment,the difference was statistically significant(t =-3.39, P 0.05). After treatment for 1 week,the scores of VAS in the treatment group was (5.18 ±1.03)poinrs,which was decreased compared with that before[(7.63 ±1.04)poinrs],the difference was statistically significant(t =4.23,P 0.05).After the treatment for 1 month and 3 months,VAS score differences were statistically signifi-cant(t =7.56,11.61,all P <0.05).In the control group,after treatment for 1 week,1 month and 3 months showed significant efficiency of 77.5%,33.3% and 11.1% respectively,which showed a downward trend.In the treatment group,after treatment for 1 week,1 month and 3 months,the efficiency were 57.7%,69.2% and 80.7%,which was a rising trend.And the efficiency was significantly higher than that of the control group,the differences were statistically significant(χ2 =5.16,17.99,P <0.05).Conclusion The treatment of trigeminal neuralgia using botulinum toxin of type A with ultrashort wave can significantly reduce pain in patients,the effect is better than lidocaine,triamcinolone acetonide and vitamin B12 .
ABSTRACT
@#Objective To investigate the effect of local insulin injection on neurological function after crushed injury of facial nerve in rats. Methods Facial nerve was crushing injured in 30 Sprague-Dawley rats, from which 20 selected rats were divided into treatment group (n=10) and control group (n=10). The treatment group was injected with insulin 250 ng/kg at innervated muscle, and the control group was injected with normal saline. They were assessed with neurologic deficit score everyday within 7 days after injection, and the regeneration of nerve fiber was observed with retrograde fluorogold labeling. Results Compared with that in the control group, the neurological deficit score was improved more 5~7 days after injection in the treatment group, and the count of fluorogold labeling cells increased more in the treatment group. Conclusion Local injection of insulin can promote the recovery of neurological function after crushed injury of facial nerve.

ABSTRACT
BACKGROUND:Radial head re-dislocation is one of the alarming complications of old Monteggia fracture. Many treatment methods have described the necessary of fracture and annual ligament reconstruction during treatment, but stil unclear. OBJECTIVE:To emphasize the practicality of annular ligament reconstruction through comparing the children’s treatment in two groups. METHODS:Twelve patients with children’s old Monteggia fracture were included for retrospective analysis. Al the patients were treated with radial head open reduction and internal fixation. Among them, five cases received ulna extending osteotomy and annual ligament reconstruction, and seven cases received ulna extending osteotomy without annual ligament reconstruction. The course was 3-18 months from damage to the clinical manifestations (an average of 9 months). Ten cases with Bado type Ⅰ and two cases were Bado type Ⅱ andⅢ. The reliability of ligament reconstruction was evaluated before and after treatment with Kim standard. RESULTS AND CONCLUSION:Al the 12 cases were fol owed-up for 22 months (8-26 months). Evaluation according to the Kim standard after treatment showed excel ent in 10 cases without abnormalities and pain, the range of motion>250 °, and no elbow was limited, the activities of daily living was 25 points;good in two cases with mild deformity and mild or intermittent pain, the range of motion was 200°-250° with elbow limited, activities of daily living was 15 points;no poor (serious deformity, pain, range of motionosteotomy was 8 weeks (6-14 weeks). The wounds were healed primarily without infection and nonunion. The results indicate that ulna extending osteotomy has great significance in keeping stability of radial head, and annular ligament reconstruction is determined by the time of injury, surgical procedures and intraoperative radial head stability.

ABSTRACT
BACKGROUND:Hepatocyte transplantation has attracted more and more attention as a therapeutic measure for liver failure and genetic metabolic liver diseases.OBJECTIVE:TO evaluate the efficacy and safety of human hepatocyte transplantation in treating hepatitis B related liver failure in one case by a 2-year follow-up.DESIGN:A case-report of 2-year follow-up.SETTING:No.9 Department of Infectious Diseases,Bioengineering Research Room,the 302 Hospital of Chinese PLA.PARTICI PANT:One inpatient with hepatitis B related liver failure was selected from the 302 Hospital of Chinese PLA.and she was diagnosed according the laboratory tests.The transplanted hepatocytes were originated frOm the healthy liver of a 24-year-old man,who had signed the protocol for liver donation before death.METHODS:The hepatocyte transplantation was completed in the Department of Radiology,the 302 Hospital of Chinese PLA in December 2004.Liver was isolated to obtain human primary hepatocytes, and then cryopreserved.The hepatocytes were transplanted into recipient spleen via femoral vein after resuscitation.The clinical symptoms,changes of blood biochemical indexes,and changes of spleen MRI signals were observed before and after operation.The patient was reexamined every half a year after operation, including liver function, blood coagulation function,B-mode ultrasonography,gastroscopy and MRI,and she was followed up for 2 years. MAIN OUTCOME MEASURES:Liver function,blood coagulation function, imaging indexes, immunological indexes,complication and rejection.RESULTS:①Totally(1-2)×1010 hepatocytes were harvested,and the viability of rewarmed hepatocytes was 60%,and finally 2×109 hepatocytes were transplanted.②Two months later,the clinical symptoms of the recipient were obviously ameliorated,and serum bilirubin and aspartate aminotransferase(AST)were obviously decreased,while prothrombin activity was markedly increased.20 months later,the MRI results showed that there was hepatocyte image in spleen.Two years after operation.the total bilirubin level was 20 μmol/L,direct bilirubin level was 7 μmol/L, alanine aminotransferase was 416.75 nkat/L,AST was 533.44 nkat/L,albumin was 37 g/L,prothrombin activity was 90%,which were all obviously ameliorated as compared with those before operation(474.5 μmol/L,340.3 μmol/L,400.08 nkat/L,1 200.24 nkat/L,38 g/L,25%).The patient left the hospital 2 months later and could do light-burdened job.No complications of hydroperitonia and liver function failure, etc.were observed,and no rejection occurred.Several reexaminations by B-mode ultrasonography all indicated the further aggravations of liver cirrhosis and esophageal varices.She was admitted to hospital for twice because of esophageal varices bleeding,and cured by endoscopic variceal sclerosis therapy.CONCLUSION:Hepatocyte transplantation can ameliorate liver function without rejection,but it cannot relieve portal hypertension.
ABSTRACT
Objective To investigate the diagnosis and the curative effects of interventional therapy by spiral CT in rupture of hepatocellular carcinoma(HCC). Methods 46 patients were checked by spiral CT and abdominal puncture of non-condensable blood. All the patients were treated by the transcatheter arterial embolization (TAE) with iodinated oil and/or gelatin sponge. Results Characteristic findings were detected in 31 patients,of which 7 patients were chiefly detected by spiral CT. The bleeding of ruptured HCCs was controlled effectively in all the cases treated by TAE without serious complications. Conclusion Spiral CT is susceptive to the diagnosis of the ruptured HCC. TAE can be the chiefly treatment in ruptured HCC with fewer serious complications.
