Objective: When the region of interest is somewhere in the middle of the volumetric data, it will be occluded by other regions of the volumetric data and will be hard to see in the reconstruction of volume rendering. In order to provide doctor with comprehensive, visual and accurate diagnostic information, fast volume dipping of medical images on GPU is proposed in the paper. Methods: The rapid volume clipping is achieved by combining the dipping algorithm with the fast volume rendering algorithm based on GPU. The technique is based on fast volume tendering of medical images on GPU. It works as follows: The space information of the section plane is sent to the shader. Then compare the position of the volume data sets with the section plane to decide whether the data is clipped or not. Our algorithm is different from the algorithm that clipping based on depth stencil. We can see the result that reconstructed from the data sets that remained from any position as long as the section plane is defined. Results: According to the shape the users defined, our algorithm can decide which parts of the volume have to be clipped. Because of using the general graphics hardware acecleration, the proposed method achieves interactive display rate. Conclusions: The experiment shows that the algorithm is significantly fast and can meet the requirements of real-time interactive rendering on the premise of ensuring imaging quality and can be used in surgery simulation and so on.

OBJECTIVETo evaluate the clinical effects of percutaneous pedicle screw fixation(PPSF) combined with percutaneous vertebroplasty(PVP) for the treatment of osteoporotic thoracolumbar fractures.

METHODSThe clinical data of 94 patients with osteoporotic thoracolumbar fractures treated from January 2014 to December 2015 were retrospectively analyzed. There were 31 males and 63 females, aged from 65 to 70 years old with an average of 67.2 years. Fracture level was T₁₁ on 15 cases, T₁₂ on 32 cases, L₁ on 29 cases and L₂ on 18 cases. The patients were divided into two groups according to different therapeutic methods. Percutaneous pedicle screw fixation combined with percutaneous vertebroplasty were applied in 43 patients(group A) and percutaneous vertebroplasty was applied to 51 patients(group B). Operation time, intraoperative blood loss, bone cement volume, postoperative in-bed time were recorded; preoperatively, 3 d, 1 year after the operation, the ratios of anterior border heights, sagittal Cobb angles, visual analogue scale(VAS) scores were compared between two groups. The condition of postoperative complication in two groups was analyzed.

RESULTSAll the patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time of group A [(96.2±28.7) min] was longer than that of group B [(31.8±10.6) min]. Intraoperative blood loss of group A[(62.2±25.5) ml] was more than that of group B [(25.4±10.9) ml]. Bone cement volume of group A [(5.5±0.5) ml] was larger than that of group B [(4.9±1.1) ml]. Postoperative in-bed time of group A[(5.1±1.8) d] was longer than that of group B[(1.8±0.7) d]. There were significant differences in operation time, intraoperative blood loss, bone cement volume, postoperative in-bed time between two groups(<0.05). Three days, 12 months after the operation, the ratios of anterior border heights and Cobb angles in two groups were significantly improved. At final follow-up, the ratio of anterior border height and Cobb angle of group A[(85.6±3.5)%, (11.9±5.3)°] were better than of group B[(84.2±4.5)%, (15.3±3.4)°](<0.05). Three cases in group B had re-collapse of cemented vertebral bodies. Postoperative at 3 d, 1 year, VAS score of all patients had significantly decreased(<0.05), and there was no significant difference between two groups(>0.05).

CONCLUSIONSCompared to simple PVP, PPSF combined with PVP in treating osteoporotic thoracolumbar fracture can obtain stronger vertebral strength and stiffness, furthermore to improve vertebral reduced effect, keeping vertebral heights, and preventing vertebral re-collapse.

Objective To explore the effect of shRNA silenced aromatic hydrocarbon receptor (AHR) on WNT signaling path-way during the differentiation of P19 cells into cardiac myocytes. Methods The eukaryotic expression vector of mouse AHR gene was designed and constructed. The interference plasmid was transfected into P19 cell and the positive stains to AHR gene silencing were screened by G418. The mRNA expression of important genes GSK3βandβ-catenin were evaluated by real-time fluorescent quantita-tive PCR during the differentiation of P19 cells. Results The constructed AHR-shRNA plasmid significantly inhibited the expression of AHR gene. Along with the differentiation of P19 cell into cardiac myocytes, in the interference group the expression ofβ-catenin gene was lower whereas the expression of GSK3βgene was elevated than those of control group with significant differences (all P<0.01). Conclusions The interference of AHR gene expression can regulate WNT signaling pathway in the development of heart.

Objective To explore the effects of miR -30c over -expression on early cardiac development of zebrafish.Methods The single -cell -stage zebrafish embryos were micro -injected with 3 different concentrations of miR -30c mimics in order to model the miR -30c over -expressed animal.Besides,the effects of miR -30c overex-pression on cardiac development were investigated.The mortality rate and the heart rate were assessed.Beside,the gross morphology and heart morphology of the zebrafish were observed.Moreover,the molecular mechanisms underlying miR -30c function in zebrafish cardiac development was explored,and in -situ hybridization was performed.Results Compared with the wild -type embryos,the mortality rate of zebrafish was increased with the rising miR -30c concen-tration.Furthermore,when the miR -30c mimic concentration was up to 8 μmol/L,the mortality rate reached 80% at 96 h post -fertilization.Simultaneously,the heart rate,which was viewed as an important index to cardiac function,was decreased.Moreover,the pericardial edema was getting worse over time with increasing concentration of overexpression. Then,the cardiac specific gene expression on the zebrafish embryos by whole -mount in situ hybridization was ex-plored.The area of the cardiac chamber was extended and the heart tube looping was negatively affected.Besides,the expression of atrioventricular canal marker genes was absent in zebrafish embryos from miR -30c over -expression groups.Conclusion miR -30c can impact the early cardiac development of zebrafish.

OBJECTIVETo discuss the suitable surgical approach and the internal fixation of unstable pelvic pelvic fractures.

METHODSFrom May 2010 to May 2015, 45 patients with unstable pelvic fractures were treated with different approaches and fixations, including 38 males and 7 females with an average age of 45 years ranging from 21 to 61 years. The course was within 2 weeks. According to Young-Burg classification, 23 patients were lateral compression injuries, 6 patients were vertical shearing injuries, 16 patients were anterior-posterior compression injuries. All patients had hip pain and limitation of motion, the X-rays showed the pelvic ring fracture.

RESULTSAll wounds healed well without complications, 45 cases were followed up for a mean period of 13 months (ranged 9 to 21 months). Patients with hip pain had a good postoperative pain relief. The post-operative X-rays showed the reduction was satisfied and the pelvic ring shaped well. According to Majeed standards, the final follow-up score was 93.5±11.6, 35 cases got excellent results, 8 were good, 2 were fare.

CONCLUSIONSThe unstable pelvic and acetabular fractures are always with compound injury. Beside the reduction, to decrease the second surgery trauma should take into consideration as well, the intra-articular reduction and the stability of the pelvic were especially valued, so combined the different approach with minimal invasive technique can get good clinical result.

OBJECTIVE: To explore the relationship between lumbar degenerative spondylolisthesis and T2WI high signal in the interspinous ligament in MRI in order to improve the understanding of the signal changes of the interspinous ligament. METHODS: The clinical data of 43 patients with clinically diagnosed lumbar degenerative spondylolisthesis were collected from March 2018 to March 2020, there were 19 males and 24 females, aged 50 to 92 years with an average of 69 years old. Using picture archiving and communication systems (PACS) to access images and record the distribution and incidence of T2WI high signal in the interspinous ligament between the slipped and non-slipped segments. Using Spearman correlation analysis to explore the relationshipbetween the T2WI high signal of the interspinous ligament and the degree of lumbar spondylolisthesis. RESULTS: Except for 8 ligaments that were not included in the statistical results due to poor image quality, 43 patients with a total of 207 lumbar vertebrae and interspinous ligaments were included in the study. According to the Meyerding classification method, 43 patients had a total of 48 segments with spondylolisthesis, 41 segments in grade Ⅰ and 7 segments in grade Ⅱ. There were 30 cases of MRI T2WI high signal in the interspinous ligament corresponding to spondylolisthesis segment, including 3 cases on L CONCLUSION In patients with degenerative lumbar spondylolisthesis, the MRI T2WI hyperintensity is more common in the interspinous ligament. The occurrence of T2WI high signal is positively correlated with the degree of spondylolisthesis, which should be payed enough attention in imaging diagnosis.
