Objective To discuss the femoral neck anteversion(FNA) of developmental dislocation of the hip(DDH) and guide operation with visual and digitalized picture in the dimensional(3D) CT.Methods Ninety children with unilateral DDH were selected,and they were analyzed using 3D CT.Children whose FNA exceed 45 degree received the subtrochanter osteotomy with images from different direction,FNA of hip was measured respectively before and after operation and was measured in normal and abnormal hips respectively,FNA of hip received respectively statistical treatment.Ninety patients (90 hips) were followed up ranging from 3 months to 2 years with the mean of 13 months.Results In the group younger than 18 months,the FNA whose in normal hips was(19.40?3.512)degree,the FNA while(68.45?12.272)degree in dysplasia hips respectively,the FNA measured after operation was (20.45?2.940) degree;in the group elder than 6 years,there were significantly statistical differences,the FNA in normal hips was(19.44?3.561)degree,in dysplasia hips respectively was(73.49?12.678)degree,while the FNA measured after operation was(18.28?1.931)degree.Clinical assessment was performed according to Mckay′s classification.The results showed that the overall excellent or good rate was 95.6%.Conclusions 3D CT method is a new accurate and convenient and reduplicative method for measuring FNA.It will be more helpful for related operations when 3D images are considered.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

ObjectiveTo evaluate the mortality and morbility of children with severe traumatic brain injury (sTBI) following treatment with decompressive craniectomy and further analyze its long-term outcomes.Methods Seventeen children with sTBI undergone decompressive craniectomy between 2004 and 2010 were retrospectively studied.Quality of life of the patients who survived the operation was assessed by using the King' s outcome scale for childhood head injury (KOSCHI).ResultsOf 17 children with sTBI,the mean preoperative Glasgow Coma Scale (GCS) score was 5.27.Five children (29％) died postoperatively,of whom three children were died of cerebral infarction.Twelve children who survived the operation were followed up for average 4.6 years,which showed the mean KOSCHI score of 4.75.Among the 12 survivors,five patients (42％) experienced posttraumatic shunt-dependent hydrocephalus and four (33％) suffered ipsilateral and/or contralateral hygroma.ConclusionsAlthough a high mortality rate is observed in the children with sTBI after decompressive craniectomy,the survived patients have satisfactory outcomes. Posttraumatic hydrocephalus and hygroma are two common complications after decompressive craniectomy for children with sTBI.

ObjectiveTo determine the impact of lupus flares on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus(SLE).MethodsData was obtained from 46 pregnancies of 44 pregnant women with SLE.The relationship between lupus flares and pregnant outcomes,and the risk factors for adverse maternal and fetal prognosis were analyzed.T-test,X2 test or Fisher's exact test and Logistic regression were used for statistical analysis.Results① Lupus flares occurred in19(41％)pregnancies(group A) and stable lupus disease was observed in 27(59％) pregnancies(group B) during pregnancy.Compared to pregnancies in patients with stable lupus disease at the conception(n=32),pregnancies in patients with unstable lupus disease at the conception(n=8) had higher lupus flare during pregnancy( 100％ vs 16％,P＜0.05).(②) The common manifestations of lupus flares during pregnancy were lupus nephritis (LN) (11 cases),skin rashes (10 cases),arthritis (7 cases),and the common complication was infection ( 11 cases).(③) The incidence of premature labor,fetal growth retardation (FGR) and fetal loss in group A was 42％,47％ and 26％ respectively,which was significantly higher than that of the group B (7％,15％ and 0 respectively)(P＜0.05).There was no difference in the incidence of preeclampsia,fetal distress and neonatal asphyxia between the two groups ( 16％ vs 7％,16％ vs 19％,5％ vs O,respectively,P＞0.05).The incidence of premature labor and FGR in patients with active LN was higher than that of patients without active LN (55％ vs 11％,64％ vs 17％,respectively,P＜0.05).(④)The binary Logistic regression analysis showed that renal impairment,hypocomplementemia,aPL and serum urea nitrogen level were independent risk factors for premature delivery,FGR,fetal loss and fetal distress.Conclusion(①) Lupus flares during pregnancy increase the incidence of premature labor,FGR and fetal loss.Active LN during pregnancy can increase the incidence of premature labor and FGR.② Renal impairment,hypocomplementemia,aPL and serum urea nitrogen level are associated with adverse fetal outcomes in pregnant patients with SLE.
