Objective:To verify the effect of Fu′s massage combined with physical therapy technology in rapidly relieving neck and low back pain caused by long-haul flight.Methods:Forty-two male volunteers were divided into 8, 12, 16, 24 and 48 h groups according to the simulated flying hours. After the completion of the simulated long-haul flight, the 5 groups of volunteers were immediately treated with Fu′s massage combined with physical factors for neck and low back pain. The Visual Analogue Scale (VAS) was used to evaluate the cervical and lumbar pain of volunteers after simulated flight and after treatment, and the treatment effect was before treatment analyzed.Results:There were significant differences in the VAS scores of cervical and lumbar regions before treatment among volunteers with different flying hours ( H=-30.15, -28.25, both P<0.001). The VAS scores of cervical and lumbar regions of volunteers in the 24 h and 48 h groups were higher than those in the 8 h group ( P=0.002, <0.001, =0.002, <0.001). The VAS scores of cervical and lumbar regions of volunteers in the 48 h group were higher than those in the 12 h group ( P=0.016, 0.001). The VAS score of cervical region of volunteers in the 48 h group was higher than that in the 16 h group ( P=0.033). After the intervention of Fu's massage combined with physical therapy, the VAS scores of cervical and lumbar regions in each group were lower than those before treatment, and the differences were significant ( t/ Z=-3.00-17.00, all P<0.05 or 0.01). Conclusions:Fu′s massage manipulation combined with physical treatment can effectively relieve the neck and low back pain caused by long-haul flight, which can be widely used as a relief method.

Objective:To explore influence of different guide wire on transradial coronary angiography (CAG). Methods:A total of 238 patients,who received successful transradial CAG in our hospital from Nov 2009 to Jan 2013,were selected.According to kinds of guide wire,they were divided into group A (n=119,used ordinary J type exchange guide wire)and group B (n=119,used loach exchange guide wire.Trafficability,supporting force and incidence rate of complications were compared between above two groups.Results:The trafficability of loach exchange guide wire was significantly better than that of ordinary J type exchange guide wire,the pass rates of elbow joint (98.3% vs.87.4%)and brachiocephalic trunk (100% vs.96.2%)were significantly higher than those of or-dinary J type exchange guide wire (P<0.01 or <0.05).For guide wire support to rotate catheter,ordinary J type exchange guide wire had obvious advantages,its success rate of left CAG (98.3%)was significantly higher than that of loach exchange guide wire (89.1%),P<0.01.There were no significant differences in incidence rate of compli-cations between two groups.Conclusion:Ordinary J type exchange guide wire could be preferred in coronary angiog-raphy,and loach exchange guide wire can be considered if the former can't pass.

Objective To evaluate dual-source dual-energy CT(DSCT) for the differentiation of urinary stone composition in vitro. Methods Ninety-seven urinary stones were obtained by endoscopic lithotripsy and scanned using dual-source dual-energy CT. The stones were divided into six groups according to infrared spectroscopy stone analysis: uric acid ( UA ) stones ( n = 10 ), cystine stones ( n = 5 ), struvite stones( n = 6), calcium oxalate ( CaOx ) stones ( n = 22 ), mixed UA stones ( n=7 ) and mixed calcium stones(n=47). Hounsfield units (HU) of each stone were recorded for the 80 kV and the 140 kV datasets by hand-drawing method. HU difference, HU ratio and dual energy index ( DEI ) were calculated and compared among the stone groups with one-way ANOVA. Using dual energy software to determine the composition of all stones, results were compared to infrared spectroscopy analysis. Results There were statistical differences in HU difference [(-17±13), (229±34),(309 ±45), (512 ±97), (201±64)and (530±71) HU respectively], in HU ratio (0.96±0.03, 1.34 ±0.04, 1.41 ±0.03, 1.47 ±0.03,1.30±0.07, and 1.49 ±0.03 respectively), and DEI( -0.006 ±0.004, 0.064 ±0.007, 0.080 ±0. 007, 0. 108±0.011 ,0. 055 ±0.014 and 0. 112 ±0.008 respectively ) among different stone groups(F=124. 894,407.028, 322. 864 respectively, P ＜0. 01 ). There were statistical differences in HU difference,HU ratio and DE1 between UA stones and the other groups( P ＜ 0. 01 ). There were statistical differences in HU difference, HU ratio and DEI between CaOx or mixed calcium stones and the other four groups (P＜0. 01 ). There was statistical difference in HU ratio between cystine and struvite stones ( P ＜ 0. 01 ). There were statistical differences in HU difference, HU ratio and DEI between struvite and mixed UA stones (P＜0. 05 ). Dual energy software correctly characterized 10 UA stones, 4 cystine stones, 22 CaOx stones and 6 mixed UA stones. Two struvite stones were considered to contain cystine. One cystine stone, 1 mixed UA stone, 4 struvite stones and 47 mixed calcium stones were considered to contain oxalate. Conclusions DSCT has the ability to differentiate urinary stone composition in vitro. With dual energy software, the UA, cystine and mixed UA stones can be differentiated from other types of stones.

Objective To evaluate the effieaey of test bolus technique with multi-slice spiral CT (MSCT) for determining the optimal scan delay time in CT Hepatic artery (HA)-portal vein (PV) angiography and multi-phase scanning.Methods MSCT liver angiography and multi-phase scanning were performed in 187 patients divided randomly into two groups.In group A (n =59),the scan delay time was set according to the subjective experiences of operators; in group B (n=128),the scan delay time was determined by test bolus technique.Abdominal aorta and superior mesenteric,vein were selected as target blood vessels,and 50 HU was set as enhancement threshold value.20 ml contrast agent was injected intravenously and time-density curve of target blood vessels were obtained,then HA-PV scanning delay time were calculated respectively.The quality of CTA images obtained by using these 2 methods were compared and statistically analysed using Chi-square criterion.Resuits For hepatic artery phase,the images of group A are:excellent in 34(58%),good in 17(29%),and poor in 8 (13%),while those of group B are excellent in 128( 100%),good in 0(0%),and poor in 0(0%).For portal vein phase,the images of group Aare:excellent in 23(39%),good in 27(46%),and poor in 9(15%),while those of group B are excellent in 96 (75%),good in 28 (22%),and poor in 4 (3%) respectively.There was statistically significant difference between the ratios of image quality in group A and group B (X2=14.97,9.18,P < 0.05).Conclusion Accurate scan delay time was best determined by using test bolus technique,which can improve the image quality of liver angingraphy and multi-phase scanning.

Objective To evaluate the clinical applications of helical CT scans in the ureteral diseases.Methods The precontrast and four-phase postcontrast helical CT scans were performed in 110 patients with ureteral diseases confirmed by clinic and pathology, and the multiplanar reformation (MPR) and three-dimensional reconstruction (3D) images were generated from the volumetric data.The ability of helical CT in detecting and diagnosing the ureteral diseases was investigated.The results were then compared with the findings of the other imaging techniques and surgery.Results Combined with axial and MPR images, the location, size, morphology, extension, and the urinary obstruction of the ureteral diseases could be clearly demonstrated in 97.3% cases, and the curved MPR was useful in directly detecting the lesions.The findings of ureteral lesion on helical CT images corresponded well with that of surgery in 81 cases. 3D reconstruction could produce a three-dimensional image that mimics conventional urography, and was useful in displaying the ureteral lesions from multiple views.Helical CT could compensate for some disadvantages of the other imaging techniques.Conclusion Helical CT, with large scanning area and high resolution, can provide comprehensive information about the ureteral diseases, and the curve MPR has the highest value.

Objective　To evaluate the clinical application of helical CT multiplanar reformation (MPR), three-dimensional reconstruction (3D) and virtual laryngoscopy (CTVL) in laryngeal and hypopharyngeal carcinoma. Methods　Axial helical CT scans were performed in 22 patients with laryngeal or hypopharyngeal carcinoma, along with MPR, 3D and CTVL. These results were compared with the findings of fiber optic laryngoscopy and surgery. Results　Combining axial and MPR images, both the accuracy in preoperative tumor staging and the diagnosis of metastatic lymph nodes were 95%. MPR demonstrated more information about the extent of tumor than axial images in 23% cases; 3D image displayed clearly the extension of tumor, the vessels and airway from multiple views. The location, size and extent of tumors found in cranio-caudal CTVL corresponded well with that of laryngoscopy, and CTVL demonstrated the relationship between the tumor and vocal cords and anterior commissure by caudo-cranial approach, which was inaccessible to fiber optic laryngoscopy in 3 cases. Conclusions　Axial images of helical CT clearly demonstrate the location, size and extent of laryngeal and hypopharyngeal carcinoma, while MPR and 3D images are useful in displaying the three-dimensional images and anatomical relation of the tumor. CTVL can clearly display the mucosal surface structures of the larynx and hypopharynx and is a good complementary method of laryngoscopy.

Objective To evaluate the clinical applications and limitations of CT virtual endoscopy (CTVE) in the auditory ossicular chain. Methods CTVE of the auditory ossicular chain was performed with 1.0 mm collimation at pitch 1.0, bone algorithm, 9.6 cm field of view, and 0.1 - 0.2 mm reconstruction interval in 40 patients with middle ear diseases. 30 cases were confirmed by surgery. Results were compared with the findings of axial high resolution CT (HRCT) and multiplanar reformation (MPR) images and surgery. Results The accuracy of CTVE images in detecting ossicular destruction was 92.6%, significantly higher than that of axial HRCT (83.9%) and multiplanar reformation (76.5%) images. CTVE could also clearty reveal the postoperative condition and congenital dysplasia of the auditory ossicular chain. Conclusions CTVE can clearly demonstrate a three-dimensional image of the auditory ossicular chain and is useful in evaluating diseases of the ear, especially the auditory ossicles. CTVE could not clearly demonstrate abnormal soft tissue within the tympanic cavity, abnormal changes of the tympanic membrane and tympanic walls, and could be easily influenced by artificial factors.
