Objective To raise final diagnosis of infant' tuberculosis of lungs and toreduce misdiagnosis by approaching baby' imaging appearance.Methods Analyzing 12 cases of infant' tuberculosis of lungs of final diagnosis during near two yeas.Results In 12 cases,8 cases were to cough up phlegm,5 cases were being breathlessness and to gasp for breath,10 cases have a temperature,hyperthermia was understanding 40 ℃,minimum was 38 ℃,4 cases have night sweat,5 cases were being symptomsis,5cases have symptom of nervous system, there were 3 cases with headache and hyperspasmia,1 case with conscious disturbance;All cases were examined by normal side projection,among these there are 6 cases were examined by plain scan and enhancement scanning of CT;There were 7cases with acute miliary tuberculosis,3 cases with primary complex,2 cases with mediastinal lymphadenectasis, 1case with pure mediastinal lymphadenectasis;1 case with secnd pulmonary tuberculosis,1 case with superior' pulmonary atelectasis lobe of left lung;3 cases with tuberculous meningoencephalitis,1 case with spinal tuberculosis,1 case with Tuberculous abdominal cavity,3 cases with pleural fluid and pleural thickening among 12 cases.Conclusion Earlier diagnosis can be reached according by Baby' imaging appearance and clinical symptom, to treat in time.

Objective To explore the efficiency, complications and probability of preserving part renal function by local renal microwave ablation. Methods The fresh pig renal pelvis full filled with 30% diatrizoate meglumine and the dogs kidney taken arterial pyelography were both ablated with microwave. Dogs were divided into three groups: measuring temperature after ablation group, single point ablation both on the two kidneys group and double points ablation on unilateral kidney group. In measuring temperature after ablation group, DSA and pathology were performed immediately after ablation. In the other groups, DSA with blood and urine samplings were taken for routine tests including renal function right after the ablation and 10 days later. Results Experiment in vitro showed conspicuous renal pelvic contraction and convolution. The group under power rate of 70, 3 min produced urine leak easily. Preliminary test in vivo with DSA showed the disappearance of local kidney blood supply. The residual renal function was related to areas of necrosis. Acute stage pathology revealed acute renal cortex medulla and pelvic cells injury. DSA of chronic stage showed no change in size of the area of ablation. The blood supply of necrotic areas was not restored. The residual kidney possessed the excretion contrast medium with no urine leaks. Upper pole of right kidney adhered with adjacent tissue, together with thickened covering. Pathology revealed fibrous proliferation around the coagulative necrosis. Conclusion Microwave ablation can inactivate the local renal tissue, and, effectively preserve the big blood vessels and function of residual kidney. No urine leaks occurred in chronic stage but easily to produce adhesions with adjacent tissue.

Objective To discuss the DSA characteristics of primary hepatocellular carcinoma (HCC) and to investigate the relationship between the DSA findings and the expression of tumor’s vascular endothelial growth factor (VEGF). Methods Fifty-four patients with pathologically-proved primary HCC were enrolled in this study. The DSA findings, including tumor’s size, lesion’s number, lesion’s margin, the degree of blood supply, the presence or absence of artreiovnous shunting (AVS), etc. were observed and analyzed. The qualitative test of VEGF of HCC tissue was made by using Elivision TMplus method, and based on the stain degree and the percentage of the positive cells a comprehensive analyse was carried out. With HE stain the pathologic classification was conducted by using Edmmond method. In this study, grade I and II were regarded as well-differentiated group and grade III and IV were regarded as poorly-differentiated group. The data were processed by software SPSSS13.0 and the results were statistically analyzed. Results The expression degree of VEGF in HCC tissue was related to the blood supply pattern, the lesion’s number, the integrity of the tumor’s border and the degree of differentiation (P 0.05). Conclusion Some DSA manifestations of primary HCC bear a certain relationship to the VEGF content in the tumor tissue. Through observing the DSA characteristics, the assessment of the invasion and metastasis of HCC can be well made, which will afford the clinical physicians a useful reference in making individualized therapeutic schedule and in estimating the prognosis.
