Purpose To explore the value of ultrasound contrast time-intensity curves in hepatic tumor qualitative diagnosis and evaluation of tumor ablation effect. Materials and Methods Forty-two patients who were clinically diagnosed as hepatic cancer or cirrhosis underwent contrast enhanced ultrasound for the tumor lesions within the liver, dynamic analysis of the lesions were executed with software SonoLiver CAP, the nature of the tumors were determined and the results were compared with those of the enhanced MRI. Ultrasound guided biopsy was followed with radiofrequency ablation treatment, two-dimensional and contrast enhanced ultrasound were executed two weeks after the ablation, and the results were compared with enhanced MRI findings during corresponding period. Results 52 tumor nodules were found with two-dimensional and color Doppler ultrasound, 65 (33 hyperplastic nodules, 32 malignant lesions) with CEUS, 65 (21 hyperplastic nodules, 44 malignant lesions) with ultrasound contrast time-intensity curves, and 61 (20 hyperplastic nodules, 41malignant lesions) with contrast enhanced MRI; pathological examination revealed that 26 of the lesions were benign and 39 were malignant;there was statistically significant difference (χ2=4.561, P<0.05) between the results of ultrasound contrast time-intensity curves and simple contrast enhanced ultrasound for the assessment of the nature of tumor;no statistically significant difference (χ2=0.003, P>0.05) was found between ultrasound contrast time-intensity curves and enhanced MRI for the assessment of the nature of tumor;there was statistically significant difference (χ2=5.298, P<0.05) between ultrasound contrast time-intensity curves and simple contrast enhanced ultrasound for the assessment of whether the tumor was malignant or benign, when taking biopsy results as the reference standard. Conclusion With ultrasound contrast time-intensity curves, dynamical, intuitive, and quantitative evaluation can be obtained for the perfusion differences between the lesion and the surrounding liver parenchyma, which provides more accurate information for qualitative diagnosis of hepatic tumors thus contains great application value in the evaluation of the effects of radiofrequency ablation for hepatic tumors.

Objective: To systematically evaluate the clinical effects of Maxing Shigan Decoction (MXSGD), a compound traditional Chinese herbal medicine, combined with Western medicine on pneumonia in children. Methods: In this study, the relative trials published from 1994 to 2008 were searched in Chongqing Weipu Database, Chinese Journal Full-text Database, Wanfang database, Chinese Biomedical Literature Database and other electronic database by using the method of Cochrane systematic review. At the same time the information from related journals, professional data and network were hand-searched. The methodological quality of the included trials was assessed by two evaluators, and homogeneous evaluation by meta-analysis was performed. Statistical analysis of clinical data was performed by using RevMan 4.2.7 software provided by the Cochrane Collaboration. Results: A total of 146 reports were found, while only eight randomized controlled trials met the inclusion criteria. The methodology quality of the reports included in the study was evaluated by the Jadad scale, and the specific random method, allocation concealment, blinding and intention-to-treat analysis were not described in all of the eight trial reports. As MXSGD combined with Western medicine group (treatment group) was compared with Western medicine group (control group), the meta-analysis indicated that the odds ratio for the total effective rate was 4.06, and the 95% confidence interval was from 2.63 to 6.27. MXSGD combined with Western medicine was good at increasing the total effective rate as compared with Western medicine, and the difference was statistically significant (P<0.000 01). Conclusion: MXSGD combined with Western medicine can improve clinical symptoms and increase the total effective rate of the patients with pneumonia in children. However, its clinical effects should be further identified by high quality, multicenter and randomized controlled trials with large-scale design.

BACKGROUND:The percutaneous pedicle screw technique effectively reduces the excessive injury of screw placement on paraspinal muscles, and promotes the recovery of the function of low back muscle after surgery. Minimal y invasive technique avoids some disadvantages such as large surgical trauma and more bleeding. Folding U-shaped hol ow pedicle screw has hol ow design and good distraction effect. After fixation, stress intensity, compression time, bending stiffness and torsional mechanical properties have been verified in the clinic. OBJECTIVE:To observe the clinical effect of folding U-shaped hol ow pedicle screw fixation combined with minimal access-posterior lumbar interbody fusion for single-level lumbar disc herniation. METHODS:Between January and December 2012, folding U-shaped hol ow pedicle screw fixation with minimal access-posterior lumbar interbody fusion was performed in 30 patients with lumbar disc herniation. The mean fol ow-up period was 12 months. Lumbago Visual Analog Scale, Oswestry Disability Index and imaging indicators were utilized to evaluate clinical therapeutic effects. RESULTS AND CONCLUSION:Preoperative Visual Analog Scale pain score and Oswestry Disability Index for al patients were 7.3±0.7 and 71.4±7.1, 2.9±0.7 and 29.8±3.6 at 3 days after surgery, showing significant differences. At 12 months, no significant difference in Visual Analog Scale pain score and Oswestry Disability Index was detected. Postoperative short-period fol ow-up demonstrated that al lumbar interbody fusion was achieved in one year. There was no complication such as implant failure or infection. These findings indicated that folding U-shaped hol ow pedicle screw fixation with minimal access-posterior lumbar interbody fusion for lumbar disc herniation showed good clinical therapeutic effects, high rate of interbody fusion and a low rate of complications and smal trauma.
