Objective To analyze X-ray findings of diaphragm and other related features in the diagnosis of hyperthyroid cardiopathy.Methods Forty cases without any other disease were taken chest plain film before therapy.The X-ray findings were analyzed.Results In all of X-ray features,low and flat diaphragm;barrel chest;increased and wide lung marking,which presented as network-like structure with mottling in bilateral inferior lung were closelv related to pathologic changes.Pneumonemia;pulmonary stasis;prominence of pulmonary artery segment;dilatation of right inferior pulmonary artery were related to othe change of heart and pulmonary circulation.Conclusion X-ray findings are closely related to the severe degree of pathologic changes in hyperthyroid cardiopathy.It is valuable for clinical diagnosis and treatment to recongnize these X-ray findings accurately.

Objective To evaluate the relationship between transverse process fractures of lumbar spine and blunt abdominal trauma.Methods 169 cases of blunt abdominal trauma were reviewed.Number and type of lumbar transverse process fractures associated intra-abdominal injuries were recorded.Results 148 fractures in 81 cases showed transverse process fractures on CT (single fractures in 43,multiple fractures in 38).Of them,the fractures were at right-sided in 28 patients,left-sided in 33 and bilateral in 20.Transverse process fractures of L 1 vertebra were most common(n=60).Transverse process fractures were associated with abdominal trauma in 15 cases (18%), both was statistically significant (?

Objective To analyze the typical and atypical X-ray findings and improve the understanding of the atypical features of breast cancer . Methods The mammographic manifestations of 61 patients with breast cancer were retrospectively analyzed . Results The X-ray findings were as follows: mass (n=39); microcalcification (n=30);localized tortuosity or disturbance of mammary gland architecture (n=4), star sign (n=3),asymmetrical and localized increased density (n=3) without mass and/or microcalcification.Conclusion Mass and microcalcification are very important and typical signs for diagnosing breast cancer, but some atypical X-ray findings can be found, including: localized disturbance of mammary gland architecture, star sign, asymmetrical and localized increased density, sometimes one of these X-ray findings is the only sign of malignancy. To recognize atypical X-ray findings of breast cancer is valuable for improving diagnostic rate.

Objective To investigate application value of two vacuum assisted biopsy systems in benign breast lesions and compare the advantages and disadvantages of EnCor and Mammotome system.Methods Vacuum assisted excision was performed on 346 benign breast lesions in 227 patients (EnCor with 103 cases, Mammotome with 124 cases) from November 2012 to May 2013, including 162 cases using EnCor system and 184 cases using Mammotome system.Results Duration of operation in EnCor group was (14.18± 4.21) minutes,in Mammotome group was (18.77 ± 7.06) minutes, and the difference was significant (P ＜ 0.001) .Weight of tissues in Mammotome group was (6.87± 3.43) g, in EnCor group was (8.32± 1.18) g, and the difference was significant (P ＜ 0.001).No significant differences were found in postoperative hematoma (P =0.58), postoperative pain (P =0.35), incidence of residual tumor (P =0.15).Conclusion Compared Mammotome group, EnCor group had significantly shorter duration.But using Mammotome system, the specimens can be observed directly.Mammotome is more suitable for women of childbearing age, it can preserve lactation function.There is no significant difference in complication and residual tumor of two vacuum assisted biopsy system in benign breast lesions.

BACKGROUND:Traditional open surgical transforaminal lumbar interbody fusion often needs a broader dissection of the paraspinal soft tissue and longer stretch time of soft tissue, induces greater surgical trauma and more blood loss. Minimal y invasive transforaminal lumbar interbody fusion (MIS-TLIF) may reduce or avoid these shortcomings. However, MIS-TLIF technique needs a process of learning curve. Correctly understanding the MIS-TLIF technique and dealing with their associated complications, have an important clinical significance. OBJECTIVE:To summarize the MIS-TLIF complications for treatment of lumbar disease, and explore the prevention and treatment strategies. METHODS:Between May 2008 and May 2012, 100 patients with lumbar disease were treated using MIS-TLIF. Al of patients had typical low back pain combined with leg pain, and were ineffective by conservative treatment for 6 months. There were lumbar spinal stenosis syndrome in 42 cases, lumbar spondylolisthesis in 31 cases, and lumbar disc herniation with lateral recess stenosis in 27 cases. The operative levels included L 3/4 in 2 patients, L 4/5 in 28 patients, L 5/S 1 in 50 patients, L 3-L 5 in 2 patients, and L 4-S 1 in 18 patients. The intraoperative and postoperative complications were recorded. RESULTS AND CONCLUSION:One patient appeared extradural hemorrhage 1 000 mL and was given blood transfusion, no complications were found. Pedicle screw malposition was found in 11 pedicle screws (11/435, 2.5%). Only one patient had new L 5 radicular pain due to impingement by the tip of a bicortical S 1 screw upon the lumbosacral trunk anterior to the sacrum. This screw was re-positioned at a subsequent procedure, with resolution of the radicular pain. Interbody cage malposition was found in 2 patients with 2 cages (2/120, 1.7%) after operations, they showed no clinical symptoms and were not treated. One patient with one cage (1/120, 0.8%) appeared cage displacement during fol ow-up, which required twice revision surgeries, one is cage re-position and the other is posterior interbody fusion. Within one month after operations, two patients had poor visualization in the right pulmonary arteriography, which was diagnosed as pulmonary embolism and was treated with thrombectomy and thrombolysis. No death and other consequence were found. Experimental findings indicate hat, MIS-TLIF is a safe, reliable and effective surgery for treating lumbar diseases, with few complications.
