With homology cloning approaches coupling with RACE (rapid-amplification of cDNA ends) techniques, the full-length coding sequence of pathogenesis-related protein PR10-1 with differential expression was cloned from the total RNA of the root of Panax notoginseng, and its function was explored furtherly. As a result, the longest 465 bp ORF (named as PnPR10-1 with the Accession No. KJ741402 in GenBank) was detected from the cloned sequence with full-length of cDNA of 863 bp. The corresponding peptide encoded consisted of 155 amino acids, contained some domains such as Bet-v-I, and showed high similarity with that from Panax ginseng by analysis of phylogenetic trees created from the alignments. Real-time quantitative PCR showed that the expression of PnPR10-1 gene was constitutive in different tissues of 1-3 year old plant, suggesting that it might be involved in growth, development, and secondary metabolism; yet it was up-regulated significantly with the infection of Fusarium oxysporum in root, suggesting that it might be involved in defense against many diseases including root rot in P. notoginseng.

According to the transcriptome dataset of Panax notoginseng, the key geranylgeranyl pyrophosphate synthase gene (GGPPS) in terpenoid backbone biosynthesis was selected to be cloned. Using specific primer pairs combining with RACE (rapid amplification of cDNA ends) technique, the full-length cDNA sequence with 1 203 bp, which containing a 1 035 bp open reading frame, was cloned and named as PnGGPPS. The corresponding full-length DNA sequence contained 2 370 bp, consisted of 1 intron and 2 exons. The deduced protein PnGGPPS contained 344 amino acids and shared more than 73% identity with GGPPS from Ricinus communis and Salvia miltiorrhiza. PnGGPPS also had specific Aspartic acid enrichment regions and other conserved domains, which belonged to the Isoprenoid-Biosyn-C1 superfamily. The quantitative real-time PCR showed that PnGGPPS expressed in different tissues of 1, 2, 3 years old root, stem, leaf and 3 years old flower, and the expression level in 3 years old leaf was significant higher than that in other organs, which suggested that it might not only be involved in the regulation of the growth and development, but also be associated with the biosynthesis of chlorophyll and carotenoids, the development of chloroplast, the shade habit and the quality formation of P. notoginseng.

Objective: In order to study the function of geranylgeranyl pyrophosphate synthase (GGPPS) gene, the CDS nucleotide sequence of GGPS was cloned from Panax notoginseng, and its prokaryotic expression was performed. Methods: The primers were designed according to the reported GGPPS gene sequence in Genbank, and the coding sequence was obtained by RT-PCR. The prokaryotic expression vector was constructed and transformed into Escherichia coli BL21 for the expression under the induction of isopropyl β-D-1-thiogalactopyranoside (IPTG). Results: The CDS of GGPS gene had a full length of 1 032 bp coding for 343 amino acids. Results of SDS-PAGE showed that a 29 000—44 000 protein was achieved and the recombinant protein was mainly in the form of insoluble inclusion body. Conclusion: The CDS nucleotide sequence of GGPPS gene was successfully cloned, and the stable prokaryotic expression was established. This study will provide a foundation for the further functional researches of GGPPS gene in P. notoginseng.

OBJECTIVETo evaluate the status of cell differentiation in nasal NK/T cell lymphomas.

METHODSThe clinical data of 88 cases of NK/T cell lymphomas were collected. Antibodies to the following antigens were used in the immunohistochemical study: T cell differentiation antigens (CD3epsilon, CD5 and CD1a); NK cell associated antigens (CD56, CD57) and antibodies of CD34 and CD38.

RESULTS(1) Clinicopathology: clinically, frequently involved sites were the nasal cavity and the pharynx. Ulceration and erosion of the mucosa were common signs. Pathologically, diffuse infiltration of the tumor cells was observed in 68 of 88 (70.45%) cases of nasal NK/T cell lymphomas. In 71 (80.68%) cases infiltrated cells were predominantly medium to large sized; (2) Differentiation status of tumor cells: the tumor cells expressed CD3epsilon in 78/88 (88.64%); CD5 in 56/88 (63.63%), CD56 in 25/88 (28.41%) and no positivity for CD1a, CD57, CD34 and CD38.

Objective To report the clinical result of repairing complex tissue defect in limb caused by traffic accident using both tissue flap transplantation and external fixer. Methods The vascular tissue flap including bone flap and muscular flap to repair the complex tissue defection ( soft tissue, bones, joints) in forearm, hand, leg, ankle and foot were applied in 36 cases. At the same time in surgery, injured bones and joints were fixed by external fixator for stabilizing and accelerating cure. Results All 36 cases were applied successfully with transplanted tissue combined with external fixator. The external fixator were moved away about 10～16 weeks post - operation in upper extremity or 6～8 months post - operation in lower extremity and all the cases recovered satisfactorily. Conclusions It is a reliable method for repairing the complex tissue defection in the limb caused by traffic accident by external fixator with traumatology and microsurgery technique. And it is also characterized as a minor injury method on transplanted bones, enables early exercise for joints, convenient observation of flap circulation and easy nursing.

Objective To illustrate the influences of walking speed and road slope on lower limb motions by quantitative analysis on the changes of joint angles and muscle activation. Method Five walking speeds and three road slopes were selected from slow to fast according to the related measurement. The gaits of 15 young women were measured using the motion capture system and the EMG signals of 8 major muscles in lower limbs were collected simultaneously. The mean joint angles of hip, knee and ankle in sagittal plane at different speeds and different slopes were calculated. The subject whose data was closest to the mean value could be easily found. Results The joint angles of the subject’s hip, knee and ankle in sagittal plane at different speeds and different slopes in a gait cycle were presented and the activation curves of the 8 major muscles during lower limb movements were obtained. Conclusions In each gait cycle, the curves of joint angles and muscle activations varied little with 5 different speeds, while curves for 3 different road slopes only showed similar tendencies but with different peaks.
