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.

To obtain the genome sequence of human bocavirus 2 (HBoV2), different regions of HBoV2 genome were amplified through PCR in fecal specimens which had been identified as single-positive for HBoV2 in 2010. A genome sequence of HBoV2 (HBoV2-NC, 5444 bp) was obtained after sequence assembly. The phylogenetic analysis showed that HBoV2-NC had the closest evolutionary relationship with HBoV2 Lanzhou strain. The predication of inverted terminal repeats of HBoV2-NC by DINAMelt showed that inverted terminal repeats were contained in HBoV2-NC 5' terminal, which had the typical stem-loop structure in other parvoviruses. Finally, some flanking sequences of HBoV2-NC were amplified by linker-PCR.

Human bocavirus 1 (HBoV1) is a novel virus that mainly causes respiratory tract infection, and it has the characteristic of genome of Parvovirus, containing three open reading frames that encode non-structural proteins NS1 and NP1 and structural proteins VP1 and VP2. Circular episome is present during the rolling circle replication of HBoV1, which provides the possibility of full genome amplification and infectious clone construction to save HBoV1. The recombination between HBoV1 and HBoV2-4 occurs frequently. With the three-dimensional culture, in vitro culture of HBoV1 provides a powerful tool for research on the pathogenesis of HBoV1. This review focuses on the molecular characteristics, association with diseases, in vitro culture, diagnosis and treatment of HBoV1.

Objective To observe the significance of preoperative peripheral serum inflammatory cyto-kines and blood routine in predicting postoperative DVT in patients with neurosurgery.Methods A total of 156 pa-tients from the Department of Neurosurgery form April 2016 to April 2017 were recruited in this study.According to the incidence of postoperative deep venous thrombosis(DVT),patients were divided into DVT group(48 cases) and non-DVT group(108 cases). The date blood routine(including hematocrit,hemoglobin,neutrophil count, monocyte count,white blood cell count,platelet count)and serum inflammatory cytokines(including TNF-α,IL-1β,IL-1β,IL-6,IL-8)of two groups by t tests were compared.The possible risk factors for postoperative DVT in neurosurgical patients were analyzed by multivariate analysis logistic regression.The predicted cutoff value is deter-mined by plotting the subject's working characteristic(ROC)curve.Results Between the control group and DVT group,there were significant differences in preoperative blood neutrophil count,hemoglobin,TNF-α,IL-6 and IL-8(P < 0.05). Multivariate analysis logistic regression showed that the level of neutrophil count and concentration of serum TNF-α concentration were increased,indicating they may be the risk factors of DVT.For the neutrophilic granulocyte count,the value of specificity and sensibility was 82.7%and 61.7%respectively.For the TNF-α level, the value of specificity was 72.3% and the value of sensibility was 83.1%. Conclusion The level of preoperative neutrophil count and the concentration of TNF-α have value in predicting the occurrence of postoperative DVT in neurosurgical patients.

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.
