Objective To study CT and MRI manifestation of untypical cystic lymphangioma.Methods CT and MRI findings of 8 cases of cystic lymphangioma proved surgically and pathologically were analyzed retrospectively.7 cases were performed by CT and the other by MRI.Results 3 lesions are located at facies cranii,2 lesions at neck,2 lesions are located at mesostenium and 1 lesion is located at chest wall.CT and MRI findings include:(1)dense mass(5 cases);(2)lesion contain solid and water dense(2 cases);(3)lesion contain high dense hematoma(2 cases);(4)calcification in lesion(2 cases);(5)infiltrate the adjacent tissue(3 cases).Conclusion Most majority cystic lymphangioma can be identified by CT and MRI which also helpful to evaluation lymphangioma before surgical treatment.

Objective Accelerated junctional rhythm (AJR) always occur during slow pathway catheter ablation for atrioventricular nodal reentrant tachycardia (AVNRT), the clinical significance of it has not been gotten in agreement. The aim of this study is to search for an association between AJR and ablation target site or tachycardia recurrence.Methods The data of 247 patients with AVNRT who received radiofrequency ablation procedure during April 1995 to October 1999 was analyzed. All these people were divided into two groups (212 patients in the successful ablation group or group 1, 35 patients in the recurrence group or group 2). The AJR was divided into two distinct pattern:type Ⅰ(continuous AJR that persisted until the end of energy delivery) and type Ⅱ (intermit AJR alternated with sinus rhythm during slow pathway ablation, which was eliminated immediately when stopping energy delivery ). Results\ The results showed that patients in group 1 exhibited better AJR response, most of them were seen with type Ⅱ AJR. However most of the people in group 2 had no AJR response throughout energy delivery , few of them had type Ⅰ AJR response. The AJR response of group 1 started relatively earlier than that of group 2(3 2?1 8 vs 5 7?2 5 ,P

Objective To discuss the pathogenesis,diagnosis and treatment of delayed traumatic intracerebral hematoma.Methods The clinic data of traumatic delayed intracranial hematoma patients in this hospital were retro- spectively analyzed.According to clinic observation and CT re-examination,47 cases were diagnosed as delayed trau- matic intracranial hematoma(45 cases by operative treatment,and the other 2 by conservative treatment).Results There were 21 cases of recovery,10 cases of slight disability,8 cases of severe disability,8 cases of death.The total mortality rate was 17 %.Conclusion Brain contusion,subarachnoid hemorrhage and skull base fracture were impor- tant factors of DTICH.Fine-observation and prompt CT re-examination offered excellent results for DTICH.

Object To investigate the effects of ultra-fine powder technique and granularity of pellets on dissolution rate in vitro. Methods The dissolution rate of ultra-fine ERMIAO PILL with different granule diameters in vitro was measured and compared with the index of berberine by UV spectro-photometry. Results The dissolution parameters T 50 and T d of four kinds of ultra-fine ERMIAO PILL are 61.60, 19.48, 17.84, 8.97 min and 102.3, 33.29, 26.98, 14.77 min, respectively. Those of general powder ERMIAO PILL with granule diameter of 2.4 mm are 89.61 and 155.68 min. Conclusion The dissolution rate of ultra-fine powder is quicker than that of general powder, and the rate increases with the granularity of PILL decreasing.

Objective To investigate the relenvant factors of precocious puberty and provide the basis for precaution of high risk group of precocious puberty .Methods A 1:1 case-control study was performed on 50 healthy girls and 50 precocious puberty girls .Results Univariate analysis showed an significant differences in the exposure rates of following five factors between cases and controls:intake of nutritious and health products ,favoring meat and poultry,long time watching television,addiction to TV ads,family economic condition (The Chi-square values are 7.045,9.073,17.478,14.063,12.246 respectively,all P<0.05).The Logisitc regression showed that favoring meat and poultry,long time watching television and addiction to TV ads had significant differences among precocious puber -ty children(The Wald′s Value were 4.846,6.850,5.662 respectively,all P<0.05).Conclusion favoring meat and poultry,long time watching television and addiction to TV play an important roles in precocious puberty .

Objective To evaluate the value of DWI in detecting active sacroiliitis in patients with axial spondyloarthritis ( SpA) .Methods DWI and conventional MRI examinations were done oblique coronary on bilateral SIJs of 19 participants,involving 8 patients (the case group) underwent clinical and conventional MRI evaluation for axial SpA active sacroiliitis and 11 healthy volunteers(the control group).The conventional MRI,DWI,ADC,EADC images were transmitted to two experienced radiologists respectively to read ,evaluate and measure ( the ADC values and EADC values ) at the workstation under the blind method .The experimental data were inputted and analyzed by statistics software .Results In the control group ,the periarticular bone marrow in the SIJ showed hopyintense signal on the DWI image ,hypointense signal on the ADC image and hyperintense signal on the EADC image .The periarticu-lar bone marrow oedema showed hyperintense signal on the DWI and ADC images , while hopyintense signal on the EADC image.At b values of 300s/mm2 ,the ADC values of the periarticular bone marrow oedema at each side in the case group were significantly higher than those in the control group , while EADC values were lower , the difference were statistically significant(Z=-3.115,-2.814,-3.002,-3.115,-3.115,-2.714,-2.889,-3.115,all P<0.05).Conclusion DWI can directly detect the signal changes ,extent of the periarticular bone marrow oedema , and analyze the severity of oedema quantitively ,which shows the utility in determining the activity and early diagnosis .
