Objective: To observe the efficacy of long-retaining scalp acupuncture plus interactive training in improving upper- extremity dysfunction in cerebral stroke patients. Methods: Ninety-five patients with upper-extremity dysfunction after cerebral stroke were randomized into two groups, with 48 cases in the treatment group and 47 cases in the control group. Conventional internal medicine treatment was offered to both groups. In both groups, Anterior Oblique Line of Vertex-temporal (MS 6, the middle 2/5) and Posterior Oblique Line of Vertex-temporal (MS 7, the middle 2/5) were selected from the same side of the brain lesion (the side apposing to the hemiplegic limb) for scalp acupuncture treatment. In the treatment group, the scalp acupuncture needles were retained for 7 h, in combination with interactive training, while the needles were also retained for 7 h in the control group but without interactive training. Prior to treatment and at 2-week and 4-week treatment, the two groups were scored using the functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK) and simplified Fugl-Meyer assessment-upper extremity (FMA-UE). Results: The total effective rate was 97.9％ in the treatment group, higher than 74.5％ in the control group (P<0.01). The FTHUE-HK score was higher at 2-week and 4-week treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FTHUE-HK score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FTHUE-HK score was higher in the treatment group than in the control group, showing significant between-group differences (both P<0.05). During the whole treatment process, the treatment group had higher FTHUE-HK scores compared with the control group, but there was no statistical significance comparing the change of the score between the two groups at 2-week treatment (P>0.05), while the between-group difference in the change of the score was statistically significant at 4-week treatment (P<0.05). The FMA-UE score was higher at 2-week and 4-weeks treatment than before treatment in both groups, presenting statistically significant intra-group differences (all P<0.001); the FMA-UE score was higher at 4-week treatment than at 2-week treatment in both groups, presenting statistically significant intra-group differences (both P<0.001). At 2-week and 4-week treatment, the FMA-UE was higher in the treatment group than in the control group, and the between-group differences were statistically significant (both P<0.01). The FMA-UE score rose gradually with the increase of treatment session, and there was statistical significance comparing the change of the score between the two groups at 2-week and 4-week treatment, respectively (both P<0.05). Conclusion: Long-retaining scalp acupuncture plus interactive training results in more significant efficacy than long-retaining scalp acupuncture alone in improving the upper-limb dysfunction after cerebral stroke and the advantage becomes more notable after 2-week consecutive treatment.

The complete chloroplast genome of medicinal plant Asarum caudigerum Hance and its close relative A. cardiophyllum Franchet were sequenced using Illumina Hiseq technology, and assembled, annotated, and characterized by bioinformatic methods in this study. Then phylogenetic analysis of the complete chloroplast genomes of A. caudigerum, A. cardiophyllum, and twelve published species was conducted. The results indicated that the chloroplast genomes ranged from 186 215-186 985 bp in length, with a large single copy (LSC, 89 445-90 169 bp) and two inverted repeats (IRa/IRb, 48 387-48 408 bp). The overall GC content was 37.4%-37.5%. A total of 144 chloroplast genes were annotated, including 98 protein coding genes, 38 tRNA genes and 8 rRNA genes. In addition, complex genomic rearrangements were detected in the chloroplast genome of Asarum. Meanwhile, visual evaluation of the discrete type of the sequence indicated that the variation level of non-coding region was higher than that of coding region. Phylogenetic analyses suggested that A. caudigerum and A. cardiophyllum were clustered into a single clade and A. cardiophyllum, A. sieboldii var. seoulense, A. misandrum and A. maculatum were clustered into another single branch. These two clade were sister species. This study provides a scientific basis for the identification, phylogenetic relationship, molecular breeding of Asarum species.

Objective:To detect the expression levels of neuropilin1 (NRP1)mRNA and miR-9 in non-small cell lung cancer (NSCLC)tissue samples, and to explore the correlations between the expressions of NRP1 mRNA, miR-9 and the clinicopathological characteristics of the patients with NSCLC.Methods:Informed consent was obtained from each patient before surgery.The tissue samples including 45 NSCLC tissue ,45 adjacent carcinoma tissue and 45 normal lung tissue were collected from China-Japan Union Hospital of Jilin University from 2010 to 2011.qRT-PCR was used to detect the expression levels of NRP1 mRNA and miR-9 in three kinds of lung tissue, and the correlation between the expressions of NRP1 mRNA, miR-9 and clinicopathological characteristics of the patients with NSCLC was analyzed.Results:Compared with normal tissue,the expression level of NRP1 mRNA in adjacent carcinoma tissue had no change (P>0.05),but the expression level of NRP1 mRNA in non-small cell lung cancer tissue was significantly decreased (P<0.05).Compared with normal tissue,the expression level of miR-9 in adjacent carcinoma tissue had no change (P>0.05),but the expression level of miR-9 in non-small cell lung cancer tissue was significantly increased (P < 0.05 ). Furthermore, in adjacent carcinoma tissue, the expression level of miR-9 in the males was lower than that in the females (P<0.05 ). In NSCLC tissue, the expression level of NRP1 mRNA had no relationship with sex,age,differentiation degree,TNM stage and clinical stage,but was significantly correlated to the histological subtype and lymph node metastasis (P<0.05).In NSCLC tissue,the expression level of miR-9 had no relationship with age, pathological type, lymph node metastasis, differentiation degree,TNM stage,and clinical stage (P>0.05),but was correlated to the sex (P<0.05). Conclusion:The expression level of miR-9 is up-regulated and the expression level of NRP1 mRNA is down-regulated significantly in non-small cell lung cancer tissue. The detection of the expression level of NRP1 mRNA contributes to j udge the histological subtype and lymph node metastasis of NSCLC.

OBJECTIVETo investigate the effect of melanoma differentiation associated gene-7/interleukin 24 (MDA/IL-24) on human hepatocellular carcinoma cell lines HepG2, MHCC97L and Hep3B and normal liver cell line L02 with a different p53 state.

METHODSThe MDA-7/IL-24 gene was transfected into human hepatocellular carcinoma cell lines HepG2, MHCC97L and Hep3B and hepatocyte line L02 with a replication-incompetent adenovirus vector. The mRNA expression of MDA7/IL-24 in HepG2, MHCC97L, Hep3B and L02 cells was confirmed using RT-PCR. Protein expression was confirmed using ELISA assay. MTT assay and flow cytometry were used to study tumor cell proliferation and cell cycle in vitro. Hoechst and flow cytometry assay after annexin-V and PI staining were performed to indicate the apoptosis effect.

RESULTSExogenous MDA-7/IL-24 gene was expressed in HepG2, MHCC97L, Hep3B and L02 cells. The protein product of MDA-7/IL-24 was confirmed in the supernatant. MTT assay and apoptosis test indicated MDA-7/IL-24 could induce growth suppression and apoptosis of HepG2, MHCC97L and Hep3B but could not in L02. Cell cycle test revealed MDA-7/IL-24 could block those cancer cells in G2/M but not in the normal cell L02.

CONCLUSIONMDA-7/IL-24 selectively induces growth suppression and apoptosis in hepatocellular carcinoma lines HepG2, MHCC97L and Hep3B in vitro independent of the state of p53 gene but not in normal liver cell L02. This indicates MDA-7/IL-24 can be a perfect gene for gene therapy in hepatocellular carcinoma.
