Objective To summarize the experience in the perioperative nursing of one-stage bilateral total hip arthroplaaty (THA) for the systemic lupus erythematosus (SLE) patients with avascular necrosis of the femoral head (ANFH).Methods From June 1998 to April 2007,17 cases of patients who were diagnosed as SLE with bilateral ANFH were treated by one-stage bilateral THA.Perioperative nursing included psychological support,diet control,observation and nursing of various complications,correct functional exercise and health education.Harris score and SF-36 score were evaluated before and after operation.Results There were 2 cases with delayed incision healing,1 with early prosthesis dislocation,1 with thigh pain for 10 months and 1 with acute renal failure postoperatively,which were improved and recovered after proper treatments.Asymptomatic deep vein thrombosis (DVT) in low extremities were detected by color Doppler ultrasonography in 6 cases.There were no pulmonary embolism and no deep infection around prosthesis.There was no Addisonian crisis postoperatively.The pain was relieved and the motion of joint was improved during follow-up.There was no radiological evidence of implant loosening.The Harris hip score and SF-36 score greatly alleviated after operation.All patients were followed up and the mean follow-up time was 28 months.Conclusions One-stage bilateral THA has good results for the patients with SLE and AVNH.Strengthening of perioperative nursing contributed to improvement of success rate of surgery and reduction of complication.

Aim To establish an allogenetic mouse skin trans-plant model,in order to provide a research model for immunosup-pressive drugs. Methods Skins from the ears of C57BL/6 mice were transplanted to the back of BALB/c mice and skin isografts ( BALB/c mice to BALB/c mice) were used as control. Cyclos-porin A( CsA) was used as a model compound to test the imm-nosuppresive effect on allogenetic graft rejection. Following the transplation and CsA treatment, the graft rejection score and graft skin survival rate were quantified. Four and nine days after transplantation,serum IL-4,IL-12 and IFN-γ levels were meas-ured using ELISA kits. Twelve days after transplantation, mice were sacrificed. The weight of spleen and thymus was obtained, and CD4 + and CD8 + population of spleenic T cells were ana-lyzed using flow cytometer. Histological features were assessed by hematoxylin-eosin( HE) staining of formalin-fixed, paraffin-em-bedded graft skins. Results After transplantion, the graft rejec-tion score increased and graft skin survival rate decreased gradu-allly. Serum IL-12 and IFN-γ levels of allograft mice increased markedly. Compared with those of isograft mice, mice with skin allograft displayed a significant increase in the percentage of the CD8 + T cell subpopulation. Remarkable inflammation, such as edema, inflammatory cell infiltration were observed in allograft mice. Compared with saline treated mice, CsA significantly re-duced the graft rejection score and improved survival rate of skin grafts. And also, CsA treated mice had smaller spleen and thy-mus. Mice that received high doses of CsA had significantly less CD8 + T cells than those treated with saline. Moreover, allograft skins in mice that received CsA had less inflammation. Conclu-sions Allogenetic mouse skin transplantation exhibits acute graft rejection. CsA can inhibit the rejection in a dose dependent manner.

Objective To investigate the correlation between neuronal injury and the expression of caspase-3 and caspase-activated deoxyribonuclease (CAD) after focal cerebral ischemia-reperfusion in rats, also to study the effect of caspase-3 particular inhibitor. Methods The focal cerebral ischemia model (occluding middle cerebral artery of the rats) was made by using modified inserting thread method and reperfusion after embolizing for one hour. Using HE staining, TUNEL staining and microscopy to observe the morphological changes of ischemic neurons at six different time points including 6,12,24,48 and 72 h, using immunohistochemistry to observe the changes of caspase-3 and CAD protein in two groups (model group and interfere group). Results There was no significant difference between the two groups using HE staining and microscopy. While there was difference of TUNEL staining positive cells in all time points, except 6 h time point; Both the two groups reached the expression peak of caspase-3 in 24 h, and the number was 2. 360± 0. 318 and 0. 804 ± 0. 206 respectively(t' = 10. 039, P < 0. 01), there was statistical significance from 12 h to 48 h between the two groups ; The expression peak time of CAD protein in two groups was 48 h, and the number was 3.061 ± 0. 567 and 0. 812 ± 0. 240 respectively (t' = 8. 960, P < 0. 01), there was statistical significance from 12 to 72 h between two groups. Conclusions Caspase-3-CAD-DNA degradation is one important way of neuronal injury in cerebral ischemia-reperfusion of rats, caspase-3 inhibitor can protect neuron in a certain degree.

OBJECTIVE: To explore the genetic etiology of Vici syndrome in a Chinese family. METHODS: Whole exome sequencing (WES) technology was used to detect gene variants in a fetus of abnormal ultrasonic structure without abnormalities in routine chromosome karyotype analysis and SNP-array. Sanger sequencing and bioinformatics prediction were performed for the suspected variants of the fetus and parents. RESULTS: The fetus and the elder sister have carried c. 2427delC (p.T809fs) and c.1886A>T (p.E629V) compound heterozygous variants of the EPG5 gene, which were respectively inherited from their mother and father. Neither variant was reported previously. According to ACMG guidelines, the c.2427delC variant was predicted as pathogenic, while the c.1886A>T variant was of uncertain significance. PolyPhen-2 and PROVEAN software indicated that c.1886A>T variant was probably damaging. CONCLUSION The c.2427delC and c.1886A>T variants of the EPG5 gene probably underlie the pathogenesis of the Vici syndrome in this family. Above finding has enriched the variational spectrum of EPG5 gene and provided a basis for genetic counseling and prenatal diagnosis for the family.
