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 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.

In the present study, the apoptotic mechanism and polyamine transporter recognition of WJH-6, a novel polyamine conjugate, were investigated in K562 and HL-60 cells. The cytotoxicity of WJH-6 was assessed by MTT assay; cell cycle distribution and apoptosis were measured by flow cytometry; the protein expression of Caspase-3, Caspase-8, Caspase-9, Bid and mitochondrial membrane potential (MMP) were evaluated by high content screening (HCS) analysis; the protein expression of cytochrome c was measured by Western blotting. The results showed that WJH-6 could be recognized and transported by polyamine transporter (PAT). Furthermore, WJH-6 was able to inhibit K562 and HL-60 cells proliferation and induce apoptosis. This apoptotic effect was relative to MMP loss, cytochrome c release from mitochondria to cytoplasm and the activation of Caspase-8, Caspase-9, Caspase-3 and Bid. These results suggested that WJH-6-induced K562 and HL-60 cells apoptosis was related with mitochondrial damage.

This study is to examine the effects of NNIspm-mediated cellular senescence of HepG2 cells and elucidate its potential molecular mechanism. Cellular senescence was detected with senescence-associated beta-galactosidase staining. Cell cycle distribution, intracellular fluorescence intensity and accumulation of intracellular reactive oxygen species (ROS) were detected by high content screening (HCS). Protein expression was detected by Western blotting. Polyamines content was analyzed by high performance liquid chromatography (HPLC). The results demonstrated that NNIspm significantly induced HepG2 cells senescence. This effect was due to the decrease of intracellular polyamines, the arrest at G0/G1 phase and an increase of ROS level. The molecular senescence marker p21 increased significantly after NNIspm treatment. In contrast, the protein expressions of Cyclin E and CDK2 were obvious down-regulation. The results indicated that cellular senescence induced by NNIspm was one of its antitumor mechanisms.
