The viral RNA was extracted from purified cymbidium mosa ic virus (CyMV) isolated from Dendrobium orchid cultivated in Hainan island. The gene of the movement protein (MP) was amplified by means of reverse transcripti on-polymerase chain reaction (RT-PCR), and cloned into pGEM-T easy vector. Se quence analysis showed that the gene fragment contained 3 open reading frames (O RFs) which may be encoding 14 kD、12 kD and 10 kD peptides. The nucleotide seque nce of the cloned gene fragment shared 97.8% homology with the MP genes of CyMV isolated from orchids cultivated in Hawaii and Singapore.

OBJECTIVETo observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).

METHODSTotally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.

RESULTSThere was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).

CONCLUSIONLH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.

To investigate the influence of Anxin granules combined with tirofiban on acute myocardial infarction (AMI) Patients after elective percutaneous coronary intervention (PCI). One hundred and twenty AMI patients were randomly divided into treatment group and control group. The patients in the two groups were all given Tirofiban 30mins before PCI . The treatment group was added Anxin granules 30 mins before and after PCI. Tissue factor (TF) and von willebrand factor (vWF) were tested at 6 hours after operation. Syndromatology alteration of traditional Chinese medicine (TCM) and bleeding complications were observed at 4 weeks after operation. Both TF and vWF at 6 hours after operation of the treatment group was lower than the control group significantly (P < 0.01), while the condition of myocardial ischemia at 90 mins after operation of the treatment group was better than control group with significance. The syndromatology alteration of TCM especially spontaneous perspiration and hypodynamia of the treatment group were improved significantly compared to control group 4 weeks after operation. All patients in both groups had no bleeding complications and thrombopenia. The study suggests that Anxin granules combined with tirofiba can improve the clinical efficacy and the endothelial function of AMI patients after PCI with no increase in bleeding events.

OBJECTIVETo evaluate the clinical and functional outcomes of infected nonunion of the tibia by internal bone transport using the LRS mono-lateral external fixation.

METHODSFrom June 2003 to October 2005, twenty-eight patients who underwent internal bone transport for infected nonunion in the tibia were reviewed. Twenty-three cases were open fractures: grade IIIA, 5 cases; grade IIIB, 11 cases; grade IIIC, 7 cases. The other five cases were infected nonunion after internal fixation. The results were evaluated by the classification of the Association for the Study and Application of the Method of Ilizarove (ASAMI) which divided into bone and functional categories.

RESULTSMean follow-up was 16 months. All the cases got primary bone union, and infection was controlled. Bone results were 14 excellent, 9 good, 2 fair and 3 poor. And functional results were 10 excellent, 13 good, 2 fair and 3 poor. The mean length of time in healing for all patients were 9 months. The mean length of regenerate bone were 6.6 cm. The most common complication was pin infection, and 2 cases refractured at the docking site.

CONCLUSIONSTibial infected nonunion can be successfully treated using the internal bone transport technique.

OBJECTIVETo develop a rapid and simple multiplex polymerase chain reaction (PCR) method which discriminates extended-spectrum beta-lactamases (ESBLs) genes in sporadic Shigella isolates from 1998 to 2007 in Hangzhou city, China.

METHODSAfter ESBLs screening according to the Clinical and Laboratory Standards Institute (CLSI) method, CTX-M, TEM, SHV and OXA-1 encoding genes were detected by using a multiplex PCR method, and the results were verified by 8 single gene PCR amplification.

RESULTSSeventeen isolates harbored ESBLs genes among 195 Shigella isolates (8.72%). Genes encoding CTX-M (17 strains), TEM (2 strains), OXA-1 (10 strains) and SHV (0 strains) were discriminated with multiplex PCR analysis, which coincided with eight single gene PCR analysis at 94.12%.

CONCLUSIONMultiplex PCR should be a suitable tool for initial rapid screening and discriminating ESBLs genes in Shigella isolates. With similar trend of national surveillance data, the proportion of sporadic Shigella isolates harbouring ESBLs genes might probably be on increase.

This study was aimed to investigate the effect of beta-elemene on proliferation and apoptosis of human multiple myeloma cell line RPMI-8226 and its mechanism. The effect of beta-elemene on the growth of human multiple myeloma cell line RPMI-8226 was detected by MTT. The effect of beta-elemene on the apoptosis of RPMI-8226 cells was determined by flow cytometry with Annexin-V/PI staining. The effects of beta-elemene on the expression of BCL-2, caspase-3, DR-4 and NF-kappaB P65 proteins were analyzed by Western blot. The results showed that the beta-elemene obviously inhibited the proliferation of RPMI-8226 cells in both time- and dose-dependent manners. Treatment with 10 - 80 micromol/L beta-elemene for 48 hours induced apoptosis of RPMI-8226 cells in a dose-dependent manner. The expression of caspase-3 and DR-4 proteins in RPMI-8226 cells treated with beta-elemene increased in a time-dependent manner, while expressions of BCL-2 and NF-kappaB P65 proteins decreased. It is concluded that the beta-elemene can inhibit the proliferation of RPMI-8226 cells by inducing the cell apoptosis. Activating the mitochondrial and death receptor pathways of apoptosis and inhibiting the anti-apoptosis pathway may involve in the beta-elemene-induced apoptosis.

Pten gene is the first antioncogene with dual phosphatase activity discovered so far, pten gene regulates the cell cycle progress, apoptosis, metastasis and invasion of the tumor cells through negatively regulating the multiple signaling transduction pathways. Multiple myeloma (MM) is a malignant tumor occurring in terminal stage of B cell differentiation. The genetic changes are considered as the important factors in MM pathogenesis, among which the deletion of antioncogene is a critical genetic change. However, little is known about the genetic change of pten in MM. This review summarizes the research advance on pten in MM including structure of pten, mechanism of pten effect and correlation of pten with MM in order to provide some references for the investigating new gene target to treat the MM.
