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.

AIM:To study the KIF21A gene mutation in a Han family with concomitant exotropia. ·METHODS: The genomic DNA of five family members was extracted from peripheral blood leukocytes and amplified with PCR. The PCR products were purified for DNA sequencing. DNA sequences were aligned with the human KIF21A gene sequences registered in GenBank. · RESULTS: Mutation analysis of all exons of the pedigree's KIF21A gene reveals no gene mutation in any of the families. ·CONCLUSION: Our study demonstrates that the KIF21A gene maybe is not virulence gene in this pedigree.

Objective To analyse the characteristics of fundus fluorescein angiography(FFA)of iatrogenic retinal vascular occlu- sion.Design Retrospective case series.Participants 9 eyes of 9 patients with iatrogenic retinal vascular occlusion and 16 eyes of 16 patients with non-iatrogenic retinal vascular occlusion in Beijing Tongren Hospital in 2002-2005.Methods All patients were examined with FFA.The difference of circulation time of retinal vessels both in iatrogenic and non-iatrogenic retinal vascular occlusion patients was compared.Main Outcome Measures The starting perfusion time and the finishing time of retinal artery or vein.Results In pa- tients with iatrogenic(4 cases)and non-iatrogenic(12 cases)central retinal artery occlusion,the finishing perfusion time was separately 79.33?87.04s and 19.20?4.61s; the finishing time of retinal vein was separately 128.07?149.11s and 33.16?15.34s.In iatrogenic(4 cas- es)and non-iatrogenic(4 cases)central retinal artery together with central retinal vein occlusion patients,the finishing perfusion time of retinal artery was separately 211.67?371.26s and 30.07?17.26s;the finishing perfusion time of retinal vein was 232.43?358.52s and 48. 81?11.64s.One patient was ocular artery occlusion.FFA showed that choroidal background fluorescence and central artery were perfused slowly,the vascular fluorescence perfusion was interrupted before it came out of optic disk and the perfusion interruption continued until late stage with extensive peripheral non-perfusion areas.Conclusion The perfusion time of the retinal artery and vein in iatrogenic reti- nal vascular occlusion may be much longer than that in non-iatrogenic retinal vascular occlusion.

Objective To determine the relationship between cigarette smoking and the incidence of systemic lupus erythematosus.Methods Database including Cochrane Library,Pubmed,OVID and Elsevier were electronically searched to collect case-control and cohort studies on the relationship between cigarette smoking and incidence of systemic lupus erythematosus.The literatures were screened and the data were extracted independently according to the inclusion and exclusion criteria.The quantitative analysis were performed by using Stata 12.0 software.Results The pooled OR values (95％ confidence interval)of current smoking and ever smoking were 1.82 (95％CI 1.42～2.34) and 1.22 (95％CI 0.96～1.56) respectively.Conclusions Our Meta-analysis revealed a moderate but statistically significant association between current smoking and development of systemic lupus erythematosus.However,it is still not confirmed whether the past smoking is one of the risk factors of systemic lupus erythematosus.

A series of andrographolide derivatives with the structure of 12-N-substituted-14-deoxyandrographolide were synthesized from the parent compound andrographolide.Their antitumor activities were preliminarily evaluated on various cancer cell lines and compound 4d stood out due to its potent growth inhibitory effect in comparison with andrographolide.Compound 4d also demonstrated significant antitumor effect on human hepatoma HepG2cells in vitro and on sarcoma 180 (S180) and hepatoma 22(H22)-bearing mice in vivo.Then,the apoptosis induced by compound 4d in HepG2cells was detected by Annexin V/PI double staining assay.Further mechanic study showed that the expression of p53 and Bax was significantly elevated and that of Bcl-2was downregulated in 4d-treated HepG2cells.Collectively,these data suggested that compound 4d had remarkable antitumor effect both in vitro and in vivo and could effectively induce apoptosis via a p53-dependent pathway in HepG2 cells,thus deserving further investigation.

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 .

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.
