Objective:To obtain the high expression of Herpes Simplex Virus Type 1(HSV-1)Glycoprotein D gene. Methods:The Herpes Simplex Virus Type 1(HSV-1)Glycoprotein D(gD1) gene fragment containing dominant antigen epitopes confirmed by computer analysis was cloned by PCR technical and inserted into plasmid vector pTrxA. Then the recombinant plasmid was transformed into Rosetta. The expressed product was analyze by SDS-PAGE. Results:930 bp gene fragment was amplified by PCR as anticipated. Nucleotide sequencing showed a 100 % homology with that of the published sequence in GenBank. The molecular weight of the expressed protein was about 48kDa, Western blotting indicated that the antigenicity of the protein was good. Conclusion:The plasmid pTrxA-gd1 was constructed and a high efficiency expression of the gd1 gene from Herpes Simplex Virus Type 1(HSV-1)strain was made. The expressed product shows a good antigenicity.

OBJECTIVETo identify the genetic alteration in human keloid.
METHODSComparative genomic hybridization was applied in 6 cases of keloid to investigate the genomic imbalance (the gain or loss of genetic material).
RESULTSThe study showed that the loss of chromosome DNA copies included chromosome, 1,7,9,13,16,17,18,19,20,22. Among them, the frequently detected chromosome loss was chromosome 1 p(66.7%), 16 (83.3%), 20 (83.3%) and 22 (83.3%). The minimum overlapping regions were 1 pter-32.2,16p13.2p11.l,20q11.1-q13.2 and 16p13.2-p11.1. Frequent gain of DNA copy numbers was not found in the special regions.
CONCLUSIONSThe mapping of DNA copy variation frequency in keloid showed that there may be inhibitory genes in chromosomes 1p,16,20,22. The loss of these genes may be involved in the development and progress of keloid.

OBJECTIVETo identify the genetic alterations in nonsyndromic cleft lip and palate (NSCLP).
METHODSComparative genomic hybridization was applied to investigate the genomic imbalance (the gain or loss of genetic material) in 7 cases of NSCLP.
RESULTSIt showed that the loss of chromosome DNA copies happened in chromosome 6, 7, 10, 13, 14, 16, 20, 22 and the gain of chromosome DNA copies happened in chromosome 5, 15, 18, 19. Conclusions 13q had a high frequency (71.4%) of chromosome loss.
CONCLUSIONSAbnormal chromosome DNA copies happen in all the patients with NSCLP. Most of the patients have chromosome DNA copies loss. It suggests that loss of inhibitory gene may be related to the NSCLP. The related inhibitory gene may locate in 13q.

OBJECTIVETo observe the effect of tensile stress on human heel skin fibroblast proliferation in vitro, providing a theoretical basis for preventing the wound edge skin necrosis and nonunion after calcaneal fracture surgery.
METHODSFibroblast cells were taken from lateral heel skin of a 40 year-old-man, then cultured and subcultured in vitro. After that, they were divided into three groups: 0 hours group, 6 hours group and 24 hours group and were tested by tensile stress testing. The levels of TGF-β1 and IL-6 in nutrient fluid were measured. Transmission electron microscope and light microscope was applied for observe mitochondria and nucleus.
RESULTSUnder 10% of the tensile stress, mitochondria decreased, the levels of TGF-β1 and IL-6 in nutrient fluid were decreased and cell proliferation was inhibited gradually with time increasing.
CONCLUSIONThe human lateral heel skin in a long-time tensile stress state is an important cause of wound edge skin necrosis and nonunion after calcaneus fracture surgery.

As the preparation process from Salvia miltiorrhiz herbs to S. miltiorrhiz injection involves complicated technology and has relatively more factors impacting quality safety, the overall quality control is required for its effectiveness and safety. On the basis of the component structure theory, and according to the material basis of S. miltiorrhiz injection, we discussed the multi-dimensional structure and process dynamic quality control technology system of the preparation, in order to achieve the quality control over the material basis with safety and effectiveness of S. miltiorrhiz injection, and provide new ideas and methods for production quality standardization of S. miltiorrhis injection.

Objective To evaluate the effect of digital subtraction angiography and transcatheter embolization for gastrointestinal hemorrhage.Methods Twenty patients with gastrointestinal hemorrhage received celiac arteries,superior mesenteric arteries and inferior mesenteric arteries angiography. Superselective angiography were performed when the arteries were suspicious by clinic or angiogrraphy.Ten patients with definite diagnosis and manifestation of hemorrhagic arteries by angiography were embolized after superseleetive catheterization with gelfoam particles,gelfoam particles and coils,polyvinyl alcohol particles. Results The positive signs were observed in 13 cases.The DSA features including contrast medium accumulation in the gastrointestinal tract outside vascular,aneurysm,tumorous vascularization and staining, artery affect and local vasospasm.The bleedings were stopped immediately in 8 patients.No rebleeding and intestinal ischaemia or necrosis were observed in 30 days.One patient died in the second day after embolization from multiple organ failure.Rebleeding occurred 3 days after embolization in another patient, and was recovered after surgical operation.Conclusion DSA is more effective for the diagnosis of gastrointestinal vascular malformation and tumors complicating acute bleeding.Transcatheter embolization is effective and safe to control the hemorrhage.
