ObjectiveTo explore the effect of neoadjuvant combined postoperative therapy on patients with hepatocellular carcinoma after radical operation. Methods41 postoperative cases were divided into 2 groups at random with 20 cases receiving hepatic artery chemotherapy embolization and biotherapy, and 21 cases receiving supporting treatment only.Results The intrahepatic tumor recurrence rate at 1 year and 2 years in treatment group was 10% (2/20) and 30% (6/20), compared with 43% (9/21) and 62% (13/21) in control group (all P

Non-surgical therapy is important to liver cancer treatment. Actinotheraphy and chemotherapy, because of their less specific for cancer tissue and serious side effect, badly affect the patients' life qualities, sometimes even endanger the patients lives. Hepatocellular carcinoma specific antibodies have been the focus of liver cancer biotherapy. After 20 years of study since 1975, it has been demonstrated that antibodies derived from mouse could not efficiently stimulate the functions of human reactor, but could induce human anti-mouse antibody responses which could bring about serious side effects. The application of DNA recombination technique provides a good method for resolving the immune selection problem. The techniques of humanoriginated antibodies and phage displaying will lead to development of innovative strategies to manage liver cancer. In our country, the antibody products aimed at cancer all originated from mouse while the study of human antibodies is still at its primary stage. Non-human antibodies has been forbidden in clinical trails by FDA in America since 2001. It can be speculated that human antibody products will domminate the future market rapidly.

Objective:To observe the clinical effect of Nie-pinching spine coupled with point application and injection for cerebral palsy (CP) in children with spleen deficiency.
Methods:A total of 70 CP children with spleen deficiency were randomly allocated into a treatment group (n=35) and a control group (n=35). Children in the treatment group were treated with comprehensive rehabilitation training, Nie-pinching spine, point application and point injection, whereas children in the control group were treated with comprehensive rehabilitation training and oral administration of multi-enzyme tablets. One course of treatment made up of 20 d. There was a 20-day interval between two courses. The cases were treated for a total of 3 courses. Then the therapeutic efficacies were evaluated using scores of spleen-deficiency symptoms and gross motor function measure (GMFM).
Results:After 3 courses of treatment, the total effective rates for spleen-deficiency symptoms and rehabilitation were 85.7% and 77.1% respectively in the treatment group, versus 51.4% and 57.1% respectively in the control group, showing statistical differences (bothP<0.05).
Conclusion:In addition to comprehensive rehabilitation training, Nie-pinching spine combined with point application and injection obtained better effects than oral administration of multi-enzyme tablets.

Objective: To observe the clinical effect of acupuncture plus occupation therapy for fine motor functions in children with spastic cerebral palsy. Methods:A total of 80 cerebral palsy kids with fine motor dysfunction were allocated into two groups by envelop, 40 cases in each group. Cases in the control group were treated with occupation therapy. Based on the therapy given to the control group, cases in the treatment group were supplemented with acupuncture at the points of the three yang meridians of hand. The treatment was done every other day and 10 times for a course. There was a 15-day interval between two courses, and 3 courses in total. The therapeutic efficacies were evaluated using Peabody developmental motor scale 2 (PDMS-2) and modified Ashworth scale (MAS) before and after treatment. Results:After treatment, the standard score for grasping (Grs), standard score for visual-motor integration (Vis), fine motor quotient (FMQ) and modified Ashworth scale (MAS) were significantly improved in both groups (P<0.05). The improvement in the treatment group was more obvious than that in the control group (P<0.01). Conclusion:Acupuncture plus occupation therapy can achieve better effect than occupation therapy alone in improving fine motor functions of upper limbs in cerebral palsy kids.

Objective To explore the diagnosis and treatment of benign paroxysmal positional vertigo (BPPV) with bilateral positive Dix-Hallpike test.Methods This is a retrospective study based on the clinical data of BPPV patients diagnosed in the Dizziness Clinic of Changzheng Hospital from January 2012 to December 2012.Totally 490 patients with vertigo and nystagmus provoked by Dix-Hallpike maneuver were included in the present analysis.Results Among all the patients,55 (11.2％) of them presented with bilateral nystagmus by the provocative test.According to the type of nystagmus provoked by DixHallpike maneuver,the 55 patients can be divided into the following four categories.(1) Bilateral geotropic (n =16) and apogeotropic nystagmus (n =5):all these patients were diagnosed with horizontal canal BPPV and free of vertigo after head side-shaking exercise in supine position and Barbecue maneuver.(2) Bilateral predominant down-beating nystagmus (n =2):patients in this group were diagnosed with anterior canal BPPV,and got recovered after Kim maneuver.(3) Bilateral torsional up-beating geotropic nystagmus (n =20):after a lying-down test,6 of the patients manifested as vertical up-beating nystagmus and 14 patientsremained torsional up-beating nystagmus.The formerwere diagnosed with bilateral posterior canal BPPV,and were cured after bilateral PRM therapy,and the latter were diagnosed with horizontal canal BPPV,who were cured after Barbecue maneuver.(4) Torsional up-beating geotropic nystagmus on one side and down-beating nystagmus on the other side (n =12).The down-beating nystagrnus on the other side disappeared when the patients was firstly seated up with head down in 30 degrees for half an hour before second Dix-Hallpike maneuver.These patients were diagnosed with unilateral posterior canal BPPV and cured by PRM therapy.Conclusions It is common for vertigo patients with bilateral nystagmus induced by Dix-Hallpike test.The diagnoses should be made by the types of nystagmus provoked step by step before maneuver therapy.

Objective To detect expression of TEL-AML1 fusion genes in pediatric cases with acute lymphoblastic leukemia(ALL) and discuss the role of reverse transcriptase polymerase chain reaction(RT-PCR)and fluorescence in situ hybridization(FISH) in detection of t(12 ;21) and the clinical significance. Methods TEL-AML1 fusion gene was identified in bone marrow munonuclear cells from 31 newly diagnosed childhood ALL patients by NRT-PCR, FISH and conventional cytogenetic analysis (CCA). Results TEL-AML1 fusion gene was found in 7 out of 31 cases, accounting for 22.6 % in pediatric ALL, and 7 out of 31 cases accounting for 25.9 % in B-ALL Seven cases were found with t (12;21) by FISH and NRT-PCR. The incidence of the t(12;21) was 22.6 % in newly diagnosed pediatric ALLs. Conclusion It is concluded that TEL-AML1 rearrangement is a frequent molecular abnormality in childhood ALL. t(12;21) is the most common cytogenetic translocations in Chinese pediatric ALLs, but it is always difficult to identify by routine CCA.Other molecular methods, e.g. NRT-PCR and FISH are powerful in detecting such a critical genetic translocation.

Objective To analyse the fusion genes derived from chromosome structural aberrations in acute myeloid leukemia(AML) and the relationship between fusion genes and the MICM classification, clinical diagnosis, chemotherapy and prognosis. Methods The expression of fusion gene in bone marrow samples was detected with multiplex RT-PCR technique and chromosome karyotypes, immunological phenotypes and clinical data were analyzed in 60 acute myeloid leukemia newly diagnosed. Results 37 cases(61.67 %) of 60 patients carried 5 kinds of fusion genes consisting of MLL-AF9, TLS-ERG, CBFβ-MYH1, AML1-ETO and PML-RARα. The activation of oncogene HOX11 was detected in 13 AML cases, three of them with other chromosome aberration simultaneously.23 cases of 31 patients carrying AML1-ETO or PML-RARα, reached complete remission(CR) after chemotherapy and without relapse. Conclusion Gene typing is the most precise classification method that can direct clinical treatment and evaluate prognosis. Multiplex RT-PCR technique, which can quickly screen 29 kinds of fusion gene derived from chromosome structural aberrations at one time, maybe helpful to improve M1CM classification and guide the choice of treatment.

Objective To explore the deletion of chromosome 13 in multiple myeloma (MM), clinical significance of FISH-defined partial deletion chromosome 13 in MM patients were investigate. Methods Fluorescence in situ hybridization (FISH ) was performed on bone marrow from 38 patients with MM to study the deletion of Rb-1 gene and locus 13q14 on chromosome 13. Fisher exact propability was used to study the relations between partial deletion of chromosome 13 and clinical features. Results 20 out of the 38 cases were found with deletion of chromosome 13; deletion of Rb-1 gene in 4 cases; deletion of locus 13q14 in 2 out of 38 cases; and 14 cases with both of deletions. Fisher exact propability showed that deletion of chromosome 13 was associated with hypso-serum lactic dehydrogenase, stage of ISS. Conclusion Deletion of Rb-1 gene and locus 13q14 were both common cytogenetic changes in MM patients with effect on the biological behavior of the disease, but the value of del (13q14) in MM needs further investigation. FISH was a rapid, accurate and sensitive technique in the analysis of del (13q14) in MM.
