OBJECTIVETo investigate the feasibility of using natural poritos as scaffolds in bone tissue engineering (TE) and repair of caprine mandibular segmental defect with titanium reticulum reinforced.

METHODSNatural poritos with a pore of 190-230 microm in size and porosity of about 50percent-65percent was molded into the shape of granules 5 mm x 5 mm x 5 mm in size. Expanded autologous caprine marrow mesenchymal stem cells were induced by recombinant human morphogenetic protein-2 (rhBMP2) to improve osteoblastic phenotype. Then marrow derived osteoblasts were seeded into poritos in density of 4 x 10(7)/ml and incubated in vitro for 48 hours prior to implantation. Then osteoblastic cells/poritos complexes were implanted into mandibular defect and the defect was reinforced by titanium reticulum. Implantation of poritos alone acted as the control. Bone regeneration was assessed 4, 8, 16 weeks after implantation using roentgenographic analysis and histological observation was done after 16 weeks.

RESULTSNew bone could be observed histologically on the surface and in the pores of natural coral in all specimens in the cell-seeding group, whereas in the control group there was no evidence of osteogenesis process in the center of the construction. The results showed that new bone grafts were successfully restored 16 weeks after implantation.

CONCLUSIONSThis study suggests the feasibility of using porous coral as scaffold material transplanted with marrow derived osteoblasts by TE method. By means of titanium reticulum reinforcement, mandibular defect could be successfully restored. It shows the potentiality of using this method for the reconstruction of bone defect in clinic.

To assess the clinical effect and safety of Chinese traditional medicine injection combined with radiotherapy for esophageal cancer. The relative randomized controlled trials (RCTs) of Chinese medical injections (CMI) combined with radiotherapy as well as simple radiotherapy for esophageal cancer were searched from PubMed, Cochrane Library, EMBASE, Chinese Biomedical Literature Database(CBM), China National Knowledge Infrastructure (CNKI), Wanfang Database and VIP Database as at September 2014. Two researchers completed the data extraction and quality evaluation independently. The data were analyzed by GeMTC 0.14.3 and Stata 12. 0 software. Finally, 43 RCTs involving 3 289 patients were finally included. The star network was constructed by different comparison groups. The results of network meta-analysis showed that the seven CMIs combined with radiotherapy was superior to simple radiotherapy in the treatment of esophageal cancer in efficacy, quality of life, and reduction in the incidence of nausea and leucopenia, but with no significant difference among the seven CMIs. Probability ranking result showed a great possibility for Shenqi Fuzheng and astragalus polysaccharide injections in improving the overall response rate and quality of life, which were followed by cinobufagin and kangai injections. However, only one study was included for Shenqi Fuzheng and astragalus polysaccharide injections. Therefore, cinobufagin or kangai injections were preferred in improving the overall response rate and quality of life. Aidi or compound sophora injections were better than other CMIs in reducing? the incidences of nausea (III-IV) and leukopenia. More RCTs of Shenqi Fuzheng and astragalus polysaccharide injections combined with radiotherapy for patients with esophageal cancer were expected in the future to confirm our results. Moreover, study findings will be reported, particularly for the adverse events in radiotherapy for esophageal cancer.

Objective: To compare the effects of various interventions on the incidence of central line-associated bloodstream infection (CLABSI) . Methods: The clinical data of 218 patients with central venous catheterization were retrospectively analyzed. Infected patients were treated as CLABSI group and non-infected patients as control group. Results: Of the 218 patients, 24 patients were developed CLABSI. There was no significant difference in sex, age, primary infection status and puncture site between CLABSI group and control group. Univariate analysis showed that axillary vein puncture could significantly reduce the incidence of CLABSI (P=0.028), and the infection rate of axillary vein puncture per 1000 days under B-ultrasound was significantly reduced by 0.93‰. The average indwelling days of deep venous catheter in patients with pulse puncture were significantly longer than those in other groups (47.32 days vs 19.90 days). The average indwelling days in patients with axillary vein puncture positioned by B ultrasound were longer than those in patients with other parts of vein puncture positioned by B ultrasound (P < 0.05). Logistic multiple regression analysis showed that the main risk factors for CLABSI were anatomically located puncture (P = 0.031) and non-axillary venous catheterization (P = 0.068). Conclusions Choosing axillary vein as the position of deep venous catheterization and using ultrasound-guided central venous puncture can reduce the incidence of CLABSI and prolong the average catheterization time.

OBJECTIVETo study the relationship between inflammation and neointimal proliferation after coronary stent implantation in porcine model.

METHODSTwenty normal minipigs were randomly divided into group A (implanted with 316L bare metal stents), group B (implanted with 605L bare metal stents), group C (implanted with PLGA coating 605L stents), and group D (implanted with rapamycin-loaded PLGA coating 605L stents). Each minipig was implanted with two same stents in left anterior descending artery and right coronary artery. Four weeks later, the animals were sacrificed and histomorphometric measurements on the stent-segment coronary arteries were made to calculate the correlation between inflammation area and neointimal area.

RESULTSGroup D had the smallest neointimal area [(0.64 +/- 0.38) mm2, P < 0. 001] and inflammation area (median 0.00 mm2, P = 0.009) among all the groups, while there were no statistical differences among group A, B, and C in neointimal area [(2.09 +/- 0.90), (2.11 +/- 1.07), and (1.42 +/- 0.35) mm2 respectively] and in inflammation area (0.22 , 0.21, and 0.09 mm2, respectively). Bivariate correlation analysis showed that the inflammation area was positively correlated with the neointimal area (P < 0.001, correlation coefficient = 0.719). When stent type, mean injury score, and EEL area were adjusted, partial correlations analysis showed that the inflammation area was still positively correlated with the neointimal area (P = 0.01, correlation coefficient = 0.498).

CONCLUSIONInflammation promotes the neointimal proliferation after coronary stent implantation. Sirolimus-eluting stent may reduce the inflammatory response.

OBJECTIVETo investigate the utilization of carrier for delivering osteoblasts and creating autogenous bone tissue in ectopic site of animal via injection.

METHODSBone marrow cells harvested from iliac bone of New Zealand rabbits were induced to differentiate into marrow stromal osteoblasts. The osteoblasts were mixed with 1.5% alginate sodium solution to generate osteoblasts/alginate composites with final cellular density of 4 x 10(9)/L. Calcium chloride was used as cross-linking agent to gel aqueous alginate solution. The marrow stromal osteoblasts/alginate composites were injected into the dorsal subcutaneous tissue of rabbits with autogenous cells transplantation. The samples were examined with X-ray and histological analysis.

RESULTSFour, eight and twelve weeks after injection, the hard knobbles were easily palpated under the dorsal skin of animals. On X-ray photograph the samples showed calcified image with more density than surrounding soft tissue, new bone formation was observed in the osteoblasts/alginate composites in histological analysis. The osteogenesis was in association with regenerated hematopoietic bone marrow.

CONCLUSIONSThese results demonstrate that new bone tissue could be created through the injection of alginate sodium treated with autogenous marrow stromal osteoblasts.

OBJECTIVETo analyze the factors affecting the accuracy of Osaka formula multiparameter ultrasound-based fetal mass estimation, thereby establishing new formulas to improve the accuracy of the estimation.

METHODSA retrospective review was conducted among 519 healthy women with singleton pregnancy. Three days before the delivery (between 37 and 42 weeks' gestation), ultrasonic measurement of the fetal weight and other indices of the fetus was routinely performed. Correlation and multiple linear stepwise regression analysis were used to correct the 3 equations, which, along with Osaka University formula, were used to predict another 219 fetuses' birth weight. The coincidence rate of the predicted value and with the actual birth weight, and the absolute error and relative error were compared between the equations.

RESULTSThe fetal abdominal area (AA) and abdominal circumference (AC) showed the most conspicuous influence on the estimated fetal birth weight, and fetal humerus length (HL) was more sensitive than femur length (FL) for the estimation. Three new regression equations were established, among which the equation 2 (fetal birth weight=1082.859+4.116xAAxHL) showed the best accuracy in clinical prediction.

CONCLUSIONAA,AC and HL are more sensitive indices for estimation of the fetal birth weight, and the equation 2 established in this study still awaits further verification for its clinical value.

OBJECTIVESTo evaluate preliminary clinical experience for combining awake craniotomy and intraoperative language brain mapping within the integrated 3.0 T intraoperative magnetic resonance imaging (iMRI) suite.

METHODSFrom December 2010 to April 2011, 11 right hand-dominant patients with left glioma were involved in, or adjacent to, eloquent cortex was carried out awake craniotomies with cortical stimulation within an integrated 3.0 T iMRI suite. Aphasia battery of Chinese was used to test the language function before the operation. During the procedure, after the occipital, temporal, and supraorbital nerves were blocked by the anesthesiologists, the head was fixed with a custom high-field MRI-compatible head holder. The skull and dura was opened as usual and language brain mapping was then performed. Language testing followed a set protocol: counting numbers from 1 to 50, naming objects, reading single words. Resection of the tumor was guided by neuronavigation system and continued until eloquent areas were encountered or the margin of assessment was reached. An interdissection MRI was acquired to evaluate the glioma removal in a movable MRI scanner after minimal draping. Meanwhile, adverse effects caused by electrical stimulation and iMRI were recorded. The follow-up speech tests were assessed on 7th day and 1 month at least after the operation.

RESULTSThe combined use of 3.0 T iMRI and awake craniotomy was performed safely in all patients. No adverse effects were reported. The duration of surgery was prolonged by 2 to 4 h. The patients' perception of iMRI during surgery was favorable. First-look MRI studies led to further resection attempts in 6/11 cases as well as a 3/11 increase in the number of gross-total resections. One week after surgery, baseline language function worsened in 4 cases. However, no patients had a persistent language deficit one month after surgery.

CONCLUSIONSAwake craniotomy and direct cortical electrical stimulation can be performed safely and effectively within a 3.0 T iMRI suite. The combination of high-field iMRI and awake craniotomy may facilitate safe removal of eloquent glioma.

OBJECTIVETo report the preliminary experience in clinical application of 3.0 T intraoperative magnetic resonance imaging (iMRI) neuronavigation system in China.

METHODSFrom September 2010 to March 2011, a consecutive series of 122 patients with intracranial lesions underwent operations in guidance with 3.0 T iMRI. A retrospective analysis was conducted regarding clinical efficiency.

RESULTSAmong 122 procedures, the numbers of intraoperative scanning were 2 - 4 times with an average of 2.6. The qualities of images were excellent. Due to the discovery and further possibility of resection of residual tumors, the ratio of gross total resection was increased from 71.7% to 90.0% in cerebral gliomas (n = 60), while from 75.9% to 93.1% in macroadenomas (n = 29). There were 6.7% of all patients occurred postoperative paralysis, but only 3.3% of patients had persistent paralysis at 1 - 2 months follow-up. There was no iMRI-related adverse event occurred. During the same period, more than 2500 patients underwent diagnostic MRI scanning.

CONCLUSIONS3.0 T iMRI neuronavigation system provides high-quality intraoperative structural, functional and metabolic images for real time tumor resection control and accurate functional preservation, resulting in an improvement in maximal safe brain surgery. The system is cost-effective.
