Objective To observe the clinical effect of emergency operative treatment on thoracolumbar compression or burst fractures using pedicle screw instrument through posterior approach and indirect reduction.Methods53 acute thoracolumbar compression or burst fractures cases injured within 4 days were accepted the emergency operation of indirect reduction, decompression and fixation using pedicle screw instrument through posterior approach. The mean percentage of traumatic vertebral body height, sagittal diameter of spinal canal, degrees of kyphosis and Frankel scoring of nerve function were evaluated before and after operation.ResultsAll cases received two weeks following-up, 47 cases had more than one-year following-up. The mean percentage of traumatic vertebral height restored from 42.28% (pre-operation) to 93.46% (post-operation); the mean degrees of kyphosis recovered from 26.44° (pre-operation) to 17.73° (post-operation); the mean percentage of sagittal diameter of spinal canal changed from 63.14% (pre-operation) to 78.55% (post-operation). All but cases with completely spinal cord injury got more than one grade nerve functional restoration. Neither later spinal cord injury nor back pain existed among the patients. Three cases emerged partial internal fixation device failure, but neither symptoms nor abnormality correction missed.ConclusionEmergency operation using pedicle screw instrument through posterior approach is a feasible and confirmatory choice in treatment of the acute thoracolumbar compression or burst fractures if the cases are selected properly.

Objective To study the inducement and prognosis of pregnancy-induced hypertension syndrom(PIH) with heart failure. Methods The clinical data of 13 patients suffered from PIH-related heart failure were retrospectively analysed. Results PIH-related heart failure was associated with no regular antenatal care, anemia, hypoproteinemia, infection of respiratory tract and fluid infusion overloading. There is no maternal mortality in 13 patients.The main prenatal diseases included asphyxianeonatorum (53 84%) low-birth weight(53 84%) and IUGR(31%). Conclusion Regular antenatal care and cardiac function monitoring should be strengthen in patients with PIH. Preventing anemia, and hypoproteinemia, treating the infection and reducing heart load could promote maternal and fetal quality in patients with PIH.

Objective To develop a new silicone coating iodine-125 (s-125I) radioactive stent, and to compare it with the traditional titanium coating iodine-125 (t-125I) radioactive stent.Methods Medical silicone solution was mixed with 125I solution, evenly applied to specific locations of stents to make the silicone-coated 125I stents.The total radioactivity of 125I solution was 24mCi, by which 20 silicone-coated 125I stents were made.A total of 20 traditional titanium stents of the same radioactivity were collected, and the utilization rate of the radionuclides of the two types of stents were compared.Results With the same amount of radioactivity, the s-125 I stent showed a higher utilization rate of nuclide [91.2％ (21 878/24 000) VS 50.1％ (12 031/24 000)] (P ＜ 0.05).Conclusion The s-125I stent has a high utilization rate of nuclide,which can save the cost and energy largely.However, the application of the s-125I stent still needs further research.

Objective To investigate the effects of miR-135a on HOXA10 expression,proliferation and apoptosis of SKOV3 cells.Methods (1) Through computer-aided algorithms,the predicted target gene of miR-135a (HOXA10)were determined.(2) miR-135a mimics,miR-135a inhibitor and negative control were transfected into SKOV3 cells,respectively.Reverse transcription (RT)-PCR,western blot analysis were used to examine the expression levels of HOXA10 at different times (24,48 and 72 hours).(3) A luciferase reporter assay was used to confirm the direct regulation between miR-135a and HOXA10.(4) SKOV3 cells proliferation at different times (24,48 and 72 hours) was detected by methyl thiazolyl tetrazolium(MTT) assay [quantified by absorbance(A)].Western blot was used to examine the expression of apoptosis-associated protein bcl-2,bax and caspase-3 in SKOV3 cells after 48 hours transfection.Results (1) HOXA10 was predicted to be the target gene of miR-135a by computer-aided algorithms.(2) RT-PCR shown that HOXA10 mRNA levels were decreased over time (24,48 and 72 hours) after miR-135a mimics transfectionin SKOV3 cells (0.94 ±0.04 vs 0.78 ±0.03 vs 0.70 ±0.03,P ＜0.05).While,the expression of HOXA10 mRNA was increased over time after miR-135a inhibitor transfection (1.14 ± 0.05 vs 1.16 ±0.03 vs 2.60 ±0.08,P ＜0.05).After transfected with miR-135a mimics or miR-135a inhibitor over 48 and 72 hours,the HOXA10 expression levels in SKOV3 cells were significantly lower or higher than each control group,respectively (all P ＜ 0.01).Western blot analysis of HOXA10 expression in SKOV3 cells confirmed the results of RT-PCR detected.(3) After cotransfection of miR-135a plasmid and pMIR-REPORT luciferase plasmid containing HOXA10,luciferase reporter assays showed that the luciferase activity reduced by 67.8％ (P ＜0.01).(4) MTT showed that SKOV3 cells growth after miR-135a mimics transfection for 48 and 72 hours were significantly lower than those in control group (0.38 ± 0.03 vs 0.52 ± 0.05,0.67 ±0.05 vs 0.75 ± 0.06 ; respectively,all P ＜ 0.05).While,SKOV3 cells transfected with miR-135a inhibitor for 72 hours grew significantly faster than that in control group (0.95 ± 0.05 vs 0.75 ± 0.06,P ＜ 0.01).After miR-135a mimics transfection,the level of bcl-2 protein was significantly lower than that in control group (0.28 ±0.06 vs 0.76 ±0.09,P ＜0.01).The activity of caspase-3 was significantly higher than that in control group (115.0 ± 2.4 vs 95.4 ± 2.1,P ＜ 0.01).While,there was no statistical difference of bax expression (P =0.142).However,after miR-135a inhibitor transfection,the expression level of bcl-2 protein was significantly higher than that in control group (0.92 ± 0.03 vs 0.76 ± 0.09,P =0.037) and the activity of caspase-3 was significantly lower than that in control group (59.5 ± 4.1 vs 95.4 ± 2.1,P ＜ 0.01).There was also no statistical difference of bax expression (P =0.066).Conclusion miR-135a may play an important role in cell proliferation and apoptosis of ovarian cancer cells by regulating HOXA10 and its downstream pathways.

The purpose of this review is to provide a summary of studies on the effectiveness nutrition education interventions used by college students. Electronic databases such as Medline, Science Direct, CINAHL (EBSCOhost), and Google Scholar were explored for articles that involved nutrition education interventions for college students and that were published between 1990 and 2011. Fourteen studies, which involved a total of 1668 college students as respondents, were identified and met the inclusion criteria. The results showed that there were 3 major forms of nutrition education interventions: web-based education, lectures, and supplement provisions. Dietary intake measures were used in almost all studies and were primarily collected with food records, recall, food frequency questionnaires, and dietary habit questionnaires. The outcome measures varied among the studies, with indicators such as consumption of food, nutrition knowledge, dietary habits, physical activity, and quality of life. Methodological issues were also identified. In general, college students experienced significant changes in their dietary habits after the interventions were employed. The highlighted methodological issues should be considered to improve the quality of similar research in future.
