Objective To present the means of localizing the kidney with ectopic ureter in order to provide the reliable ground for surgical strategy. Methods Clinical manifestation study,IVU,SPECT imaging and cystoscopy were conducted.All the 58 patints are female with a mean age of 3.4 years.According to the creteria presented in reference,5 were type Ⅰ,42 type Ⅲ,1 type Ⅳ,8 type Ⅴ and 2 type Ⅵ. Results Operative finding revealed the accurate localization and diagnosis rate of IVU has been 95%(40/42) in type Ⅲ ectopic ureter,B-ultrasonograph 27%(12/53),SPECT 37%(6/16).With the combined consideration of imaging procedures and cystoscopy,the accurate localization and diagnosis rate has been 98%(57/58). Conclusions Combined use of imaging procedures and cystoscopy would improve the localization and diagnosis rate.Cystoscopy is the most reliable except in type Ⅲ ectopic ureter.

Objective To investigate the effect of different temperature moxibustion on serum IL-1β, IL-2 and TNF-αcontents in acute adjuvant arthritis rats and provide a basis for the mechanism of local anti-inflammatory and immune action of moxibustion. Methods A rat model of adjuvant arthritis (AA) was made by Freund’s complete adjuvant (FCA) modeling method. Of 32 SD rats, 8 were randomly selected as a normal group and the other 24 for model making. After successful model making, the rats were randomly allocated to model, treatment 1 and treatment 2 groups, 8 rats each. Treatment 1 and 2 groups received moxibustion. Local temperature at moxibustion point was controlled at (38±1)℃in treatment 1 group and at (45±1)℃in treatment 2 group. Rat serum IL-1β, IL-2 and TNF-αcontents were measured by enzyme-linked immunosorbent assay (ELISA). Results There were statistically significant differences in serum IL-1β, IL-2 and TNF-αcontents between the model, treatment 1 or treatment 2 group and the normal group (P<0.01). There was a statistically significant difference in serum IL-2 content between treatment 1 and the model groups (P<0.01). There were statistically significant differences in serum IL-1β, IL-2 and TNF-αcontents between treatment 2 group and the model or treatment 1 group (P<0.01). Conclusions Moxibustion has a reducing effect on serum IL-1βand TNF-αcontents and a raising effect on IL-2 content. 45℃moxibustion temperature can improve the effect of moxi bustion. The anti-inflammatory action of moxibustion may be through the mechanism of reducing serum IL-1βand TNF-αcontents and raising IL-2 content, which relieve body inflammatory reaction. The action of moxibustion needs proper moxibustion temperature.

Objective To study the role of CT in the evaluation after patellar dislocation triple surgeries.Methods Retrospectively analysed the CT measurements of 60 recurrent patellar dislocation patients (61 knees),who had undergone patellar dislocation triple surgeries,within one month before and after procedures.The measurements included patellar tilt angle,lateral patellar displacement,trochlear con-gruence angle,Tibial Tuberosity-Trochlear Groove distance,Insall-Salvati Ratio and Caton-Deschamps Index.Moreover,the troch-lear dysplasia classifications of all patients were evaluated.In addtion,an analysis has also been completed for 40 (41 knees)of 60 patients who had second postoperative CT examinations as follow-up assessment 3 to 6 months after surgeries.Results All one-month postoperative measurements decreased obviously with statistical significance(P <0.05 ).Furthermore,one case of subluxa-tion,1 1 cases of abnormal Tibial Tuberosity-Trochlear Groove distance,13 cases of abnormal Insall-Salvati Ratio and 14 cases of Ca-ton-Deschamps Index abnormities were also observed.Besides that,it was also found that all patients had trochlear dysplasia and 5 cases were diagnosed with patellar subluxation or dislocation at the second postoperative follow-up assessment.Conclusion The patients with redislocation or risks for patellar instability can be detectecd by CT which provides objective evidence for postoperative evaluation and further treatments.

Objective To study characters of pathology associated with functional alteration of primary brainstem injury (PBI) at different injury severities in rabbits .Methods Animal model of graded PBI was produced using rabbits .Animals were di‐vided into five groups ,group Ⅰ to Ⅳ with an increase of impact power ,10 cases in each group ,and the control group with 5 cases . The pathology characters of PBI were investigated combining dissection observation with unaided eye ,tissue HE histochemical stai‐ning and electron microscope .Results Slight brainstem injury were observed in group Ⅰ ,and pathological results showed regional subarachnoid hemorrhage (SAH) ,stripping of regional cerebral pia mater ,a few petechial hemorrhage in surface ,nerve cell edema , normal medulla sheath and axon roughly .The brainstem injuries were apparent in group Ⅱ ,and the pathological changes indicated SAH in sheet ,petechial and sheeted hemorrhage in surface ,and slight swelling and vacuoles in nerve cells .The brainstem injuries were observed obviously in group Ⅲ ,exhibiting thick SAH ,petechial and sheeted hemorrhage in surface and inside ,degeneration of nerve cells ,abruption of axon ,and atrophy of axoplasm .Eight of ten animals died of respiratory depression induced by brainstem in‐jury in group Ⅳ ,presenting thick hemorrhage in subarachnoid surrounding brainstem ,the whole brainstem injured ,microscopically with multiple small hemorrhage ,nerve cells only residual nuclei ,myelin lamellar severe stratification and fracture ,and axonal tran‐section ,disintegration .No abnormal pathological changes were shown in control group .Conclusion The impacts to brainstem with higher powers lead to more manifest functional and more severe pathological changes ,with an alternation of injury location from surface to deep .

? amyloid protein(A?) including A?40 and A?42 are the important bioactive substances in vivo.Their toxic and beneficial attributes in the body depend on its concentration.The brain A? level is maintained by two balances under the physiological condition.The first balance is the generation involved in ?-secretase and ?-secretase and the degradation involved in neprilysin(NEP) and insulin-degrading enzyme(IDE) of A?. The second one is the balance between the receptor for advanced end glycation products(RAGE)-mediated influx and low-density lipoprotein receptor related protein 1(LRP1)-mediated efflux of A? across the blood-brain barrier(BBB).Breakdowning any one of the two balances would result in the aggregation and precipitation of A? in the brain,which is a crucial event in the pathogenesis of Alzheimer's disease(AD).This paper reviews the regulation of brain A? level under the physiological condition and the reducing strategies on the level of brain A? under the pathological condition for developing new drugs in the treatment of AD.

Objective To evaluate the clinical application and safety of CT-guided transthoracic cutting needle lung biopsy in diagnosing diffuse lung diseases. Methods By using automatic biopsy gun (14 & 16 gauge), CT-guided transthoracic cutting needle lung biopsy was performed in 29 cases with diffuse lung diseases. The samples obtained were sent for pathological and immunohistochemical examination. The sampling successful rate, the diagnostic accuracy and the occurrence of complications were analyzed. Results Technical success rate was 100%, and large size of sample enough for pathological and immunohistochemical examination was obtained in all 29 cases. Definite pathological diagnosis could be made in 25 cases, with the positive diagnostic rate of 82.8%. The main complications included pneumothorax and pulmonary hemorrhage. The symptoms in most cases were not severe and disappeared within one week after the treatment. Conclusion For the diagnosis of diffuse lung diseases, CT-guided transthoracic cutting needle lung biopsy is a safe, easy, effective and reliable method with high successful rate, high diagnostic value and fewer complications, in these respects this technique is superior to transbronchial lung biopsy, open lung biopsy and video-assisted thoracoscopic lung biopsy. Therefore, this technique should be popularized in clinical practice.
