OBJECTIVETo construct tissue-engineered neural complex in vitro and study its effect in repairing acutely injured spinal cord in adult rats.
METHODSNeural stem cells were harvested from the spinal cord of embryo rats and propagated in vitro. Then the neural stem cells were seeded into polyglycolic acid scaffolds and co-cultured with extract of embryonic spinal cord in vitro. Immunofluorescence histochemistry and scanning electron microscope were used to observe the microstructure of this complex. Animal model of spine semi-transection was made and tissue-engineered neural complex was implanted by surgical intervention. Six weeks after transplantation, functional evaluation and histochemistry were applied to evaluate the functional recovery and anatomic reconstruction.
RESULTSThe tissue-engineered neural complex had a distinct structure, which contained neonatal neurons, oligodendrocytes and astrocytes. After tissue-engineered neural complex was implanted into the injured spinal cord, the cell components such as neurons, astrocytes and oligodendrocytes, could survive and keep on developing. The adult rats suffering from spinal cord injury got an obvious neurological recovery in motor skills.
CONCLUSIONSThe tissue-engineered neural complex appears to have therapeutic effects on the functional recovery and anatomic reconstruction of the adult rats with spinal cord injury.

OBJECTIVESepsis remains a serious clinical problem because of high morbidity and mortality. The importance of Toll-like receptors (TLRs) for the induction of immune responses against sepsis was demonstrated in humans. The present study aimed to probe the gene polymorphisms of TLR4 (Asp299Gly and Thr399Ile) and TLR2 (Arg753Gln) in patients with sepsis among Chinese Han children in Wenzhou, and investigate the correlation with sepsis.
METHODThis study was conducted as a case-control study. Using polymerase chain reaction and DNA sequencing, gene polymorphisms of TLR4 (Asp299Gly and Thr399Ile) and TLR2 (Arg753Gln) in 59 children with sepsis, 38 children with severe sepsis (including 20 septic shock) and 57 healthy controls were analyzed. Hardy-Weinberg method of statistics was used to compare the frequency of genotypes alleles among three groups.
RESULTThe mutant genotypes of TLR4 gene (Asp299Gly and Thr399Ile) were not found among sepsis, septic shock and control groups. In severe sepsis group, the Arg753Gln TLR2 polymorphism occurred in 2 out of 38 severe sepsis patients and both of the subjects with the TLR2 Arg753Gln polymorphism had fatal staphylococcal infections.
CONCLUSIONTLR4 gene (Asp299Gly and Thr399Ile) polymorphisms may not be correlated with susceptibility to sepsis among Chinese Han children in Wenzhou. The fact that only 2 out of 38 severe sepsis patients had Arg753Gln TLR2 polymorphism suggests that a larger sample size is needed because of the rarity of the TLR2 allele among Chinese Han children in Wenzhou.

OBJECTIVETo determine the difference of post-operative mortality between ORIF (open reduction internal fixation) and hip replacement for the treatment of intertrochanteric fracture in elderly by using survival analysis.
METHODSThe clinical data of 110 patients above 60 years old who underwent surgical treatment (ORIF or hip replacement) for the intertrochanteric fracture between April 2003 and May 2013 were retrospectively analyzed. Among the patients, 83 cases were treated with ORIF (ORIF group), there were 32 males and 51 females, aged from 61.44 to 98.75 years old with an average of (78.52 ± 7.98) years old; and 27 cases were treated with hip replacement (arthroplasty group), there were 8 males and 19 females, aged from 71.82 to 96.54 years old with an average of (79.99 ± 6.11) years old. A survival analysis was performed on the clinical data by using SPSS 110 software. The survival rate of 1-year,2-year, 5-year and the mean survival time for the total patients, the mortality rate of 1-year, 2-year in each group, the survival rate of 1-year, 2-year and mean survival time and survival curve in each group were included.
RESULTSAll wounds achieved primary healing and no deaths were found in stay hospital. All patients were followed up from 1 to 125 months with an average of (46.93 ± 29.53) months. Among all 110 cases, 31 were dead and 79 survived. The survival rate of 1-year, 2-year and 5-year was (90.7 ± 2.8)%, (82.5 ± 3.9)% and (57.6 ± 6.5)%, respectively,while the ensemble mean survival time was (84.137 ± 5.902) months. The mortality rate of 1-year, 2-year in ORIF group was 7.2% and 12.0%, respectively; and in arthroplasty group, there was 14.8% and 25.9%, respectively. There was no significant difference in mortality rate of 1-year and 2-year between two groups. According to the survival analysis of the ORIF group, the survival rate of 1-year, 2-year was (92.6 ± 2.9)%, and (85.8 ± 4.3)%, respectively, and the mean survival time was (87.508 ± 6.063) months. In arthroplasty group, the survival rate of 1-year, 2-year was (85.2 ± 6.8)% and (73.9 ± 8.5)%,and the mean survival time was (67.294 ± 11.180) months. There was significant difference in mean survival time between two groups (P < 0.05).
CONCLUSIONORIF can achieve a better postoperative survival compare with hip replacement in treating intertrochanteric fracture in elderly.

OBJECTIVETo investigate the telomerase activity and to document biological behaviors of HeLa cells upon treatment with specific PI3K/AKT signaling pathway inhibitor, LY294002.
METHODSCCK-8 assay was used to determine IC50 of LY294002. The expressions of total AKT and phosphorylation AKT (P-AKT) were determined using Western blot. Telomerase activity of cell was measured by TRAP-ELISA assay. Cell growth curve, flow cytometry technique and Hoechst33258 stain were used to evaluate the cell growth, cell cycle and apoptosis respectively. Cell migration was determined by cell wound healing assay.
RESULTSIC50 value of LY294002 of treated HeLa cells was 1.73 mg/L. Western blot showed that LY294002 enabled to decrease P-AKT activity in the presence of same total AKT protein. The cell telomerase activity was decreased to 36.72% in contrast to 98.61% of the control. LY294002 decreased the telomerase activity in HeLa cells, and the growth capacity of the cells was significantly suppressed. The number of cells at G0/G1 phases increased to 66.88% compared with that of the control cells (47.36%). The apoptosis rate also increased from 2.4% to 14.9%. The relative migration distance decreased to 24.6% compared with that of control (62.57%).
CONCLUSIONLY294002 inhibition of PI3K/AKT signaling pathway leads to alteration of telomerase activity along with changes of the biological behaviors of the HeLa cells suggesting that regulation of telomerase activity may be closely related to PI3K/AKT signaling pathway.

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 investigate biological characteristics of rat bone marrow mesenchymal stem cells (MSC) cultured in vitro and to explore their potential applications.
METHODSMSC were isolated from rat bone marrow by density gradient centrifugation and were induced to differentiation. Flow cytometry was used to characterize their surface antigen expression, cell cycle status and cell growth parameters. Telomerase activity was determined by TRAP-ELISA assay.
RESULTSFusiform MSC became larger and flattener with increasing passages of culture. After the fourth passage, the MSC showed an immunophenotype of CD29 (94.75% +/- 3.68%), CD71 (95.43% +/- 2.23%), and CD90 (98.08% +/- 3.88%). After the seventh passage, MSC with such immunophenotype decreased with CD29: 50.00% +/- 3.35%, CD71: 50.70% +/- 2.43%, and CD90: 48.60% +/- 2.83%. Cells with such immunoprofile completely disappeared after passage 9. Overall, MSC grew faster during the first 5 passages. The number of MSC in S and G(2)/M phases were 38.36% +/- 2.01% and those in G(0)/G(1) phase were 61.64% +/- 2.13% after 3 passages. The cell growth decreased after passage 7. Percentage of MSCs in S and G(2)/M phases was 10.83% +/- 1.63% and that in G(0)/G(1) was 89.17% +/- 1.96% after passage 12, after which the cells failed to further divide. After passage 9, MSCs lost their ability to differentiate to Von Kossa and oil red O positive staining cells. In addition, telomerase activity of MSC also gradually decreased with the prolonged passages, from the original 52.7% +/- 0.78% to no telomerase activity.
CONCLUSIONThe biological and immunophenotypical characteristics of cultured MSC showed obvious alterations with increasing numbers of passage of culture.

Objective To retrospectively study revisions for infected total hip replacements in 30 cases and discuss the bacteriological characters of the infected total hip replacements,difficulties and strategies in the revision.Methods Thirty revisions of infected total hip replacements were reviewed retrospectively.There were 12 males and 18 females,with mean age of 62.5 years(31-86 years)at revi- sion surgery.Infection was presented one month to four years(mean seven months)after THA operation. The diseases for initial operation included femoral neck fractures in 12 cases,femoral head necrosis in 11,hip osteoarthritis in five and rheumatoid arthritis in two.Twelve eases were treated by one-stage revi- sion and 18 by two-stage revision.Results Before the revision operation,the hip infection were diag- nosed by bacterial culture in 18 cases including five with Staphylococcus epidermidis,four with Staphylo- coccus aureus and nine with other bacteria.Bacteria growth appeared on the specimens from 23 hip joints during the revision surgery but not on the specimens from seven hip joints.Of 12 one-stage revisions,10 cases were followed for mean 16 months,which showed infection recurrence in two eases.Of 18 two-stage revisions,13 cases were followed for mean 20 months,which showed one case with infection recurrence. The mean Harris hip score was improved from preoperative 44 to 84 at follow-up.Conclusions 1) The main bacteria in the infected hip are antibiotic resistant Staphylococcus.2)Because the revision op- eration is difficult,careful preparation before revision is important for success.The fresh surgeon should not attempt.3)The revision strategies should vary according to specific status of the cases.The infection recurrence rate is lower when using a two-stage revision strategy.4)Application of antibiotic bone cement can help improve treatment effect and facilitate functional recovery of the joints.5)The scientific rehabil- itation after operation is very important to functional recovery.
