Objective Evaluate the outcome of aortic root reconstruction on the analysis of the risk factors influencing surgical results. Methods Between August 1996 and November 2009, 92 patients(56 men, 36 women) aged from 14 to 77years [mean (44.8 ±1.4) years] with aortic root aneurysm underwent aortic root reconstruction. 72 patients had over moderate aortic valve insufficiency. 47 patients suffered from Marfan syndrome. The aortic pathology was aortic dissection in 45. Bentall technique was used in 59 patients, the button technique in 13, the David I with the Valsalva graft in 6 patients and the aortic valve resuspension in 14 patients. Results The hospital mortality rate was 8.7%. The major complications 31. 7%. 18patients died during the period of follow-up. Late complications among 55 survivors were 12. Univariate predictors of the morbidity were the presence of male, non-Marfan, concomitant procedure, deep hypothermia cardiac arrest, aortic cross clamp time and blood infusion. Risk facts for mortality were emergent or urgent operation, aortic dissection, concomitant procedure, aortic cross clamp time and blood infusion. Multivariate analysis revealed risk factors of concomitant procedure and blood infusion were responsible for both morbidity and mortality. The overall long-term survival rate is (97.1 ±2.0)% at 1-year, (88.1 ±4.7)% at 5-year, (54.0 ±9.2)% at 10-year. The mean for survival time is (9.9 ±0.59) years, 95% confidence interval 8.70 -11.01. Conclusion The aortic root restitution procedures are safe and effective in general. The short and long-term outcome is satisfactory. The button technique is the first choice for reimplantation coronary patch. Valve-sparring aortic root reconstructions show promise in safety and applicability.

Objective To investigate the value of KIM-1 and NGAL in predicting the early diabetes nephropathy(DN).Meth-ods 132 cases of type 1 and type 2 diabetic patients were recruited in this study,patients were divided into four groups based on the urine albumin/creatinine and serum creatinine levels,as follows:normal albuminuria group (45 cases),mi-croalbuminuria group (36 cases),clinical albuminuria group (30 cases),renal failure group (21 cases),65 healthy subjects were recruited as control group.Urinary KIM-1 and NGAL levels were measured by enzyme linked immunosorbent assay (ELISA).Results With the progress of DN,urinary KIM-1 and NGAL levels gradually increased (P<0.05),the urinary KIM-1/Ucr level was positively correlated with ACR (r=0.822,P<0.01),and the urinary NGAL/Ucr was positively cor-related with ACR (r=0.842,P<0.01).Conclusion The urinary KIM-1 and NGAL level can predict the occurrence of ear-ly DN,and also monitor the progression of DN.

By co-culturing humm mesenchymal stem cells (hMSCs) and human umbilical rein endothelial cells (HUVECs) under hypoxia and creating a microenvironment similar to that of transplanted hMSCs for the treatment of avascular ni ANFH, the effect of hMSCs on survival, apoptosis, migration and angiogenesis of human umbilical vein endothelial cells (HUVECs) under the hypoxic condition were investigated in vitro. hMSCs and HUVECs were cultured and identified in vitro. Three kinds of conditioned media, CdM-CdM(NOR), CdM-CdM(HYP) and HUVEC-CdM(HYP) were prepared. HUVECs were cultured with these conditioned media under hypoxia. The survival rate, apoptosis rate, migration and angiogenesis of HUVECs were respectively detected by CCK-8, flow cytometry, Transwell and tube formation assay. The content of SDF-1α, VEGF and IL-6 in CdM was determined by ELISA. Our results showed that hMSCs and HUVECs were cultured and identified successfully. Compared with MSC-CdM(NOR) and HUVEC-CdM(HYP) groups, the survival rate, migration and angiogenesis of HUVECs in MSC-CdM(HYP) group were significantly increased while the apoptosis rate was declined (P<0.05). Moreover, the expression of SDF-1α, VEGF and IL-6 in MSC-CdM(HYP) group was up-regulated. Under hypoxia, the apoptosis of HUVECs was inhibited while survival, migration and angiogenesis were improved by co-culture of hMSCs and HUVECs. The underlying mechanism may be that hMSCs could secrete a number of cytokines and improve niche, which might be helpful in the treatment of femoral head necrosis.

OBJECTIVE:To study the effects of Tanshinone capsules on glucose and lipid metabolism and serum sex hormone level in rats with polycystic ovary syndrome (PCOS). METHODS:90 female SD rats were randomly divided into normal group (distilled water),model group (distilled water),positive control group (metformin 200 mg/kg) and Tanshinone capsules low-dose,medium-dose and high-dose groups(30,60,90 mg/kg),with 15 rats in each group. Those groups were induced PCOS mod-el except for normal group;after modeling,those groups were given relevant medicine intragastrically for consecutive 28 d,once a day. The ovulation rate was compared before intervention and 28 d after intervention. Body weight,fat wet weight,fasting insulin (FINS),fasting blood-glucose (FPG),AUC of glucose,HOMA-IR,ISI,serum levels of FSH,LH and T were detected. RE-SULTS:Compared with normal group,anovulation,body weight,fat wet weight,FINS,FPG,AUC of glucose,HOMA-IR, FSH,LH and T were all increased significantly in model group,while ISI decreased significantly(P<0.05). Compared with mod-el group,ovulation rate and ISI of positive control group and Tanshinone capsules groups were increased significantly after interven-tion, while body weight (except for Tanshinone capsules low-dose group), fat wet weight (except for Tanshinone capsules low-dose group),FINS,FPG,AUC of glucose,HOMA-IR,FSH,LH and T were all decreased significantly(P<0.05),especial-ly in Tanshinone capsules high-dose group and positive control group. CONCLUSIONS:Tanshinone capsules can regulate glucose and lipid metabolism and serum sex hormone secretion disorder in PCOS rats.

Objective To evaluate the clinical effects and experiences of short stem ceramic-on-ceramic total hip arthroplasty in the treatment of young and middle-aged patients with femoral head necrosis.Methods From December 2009 to March 2011,40 patients with femoral head necrosis were treated primarily with short stem ceramic-on-ceramic hip arthroplasty (43 hips) through posterior-lateral or anterior-lateral approach.There were 23 males,17 females； with the mean age of 40.5 years (range,27-55 years).All cases were stage Ⅳ or more according Steinberg stage.The patients were followed up at the 3,6,12 months after operation,and then once each year.Standard X-ray films were taken at the follow-ups.Femoral prosthesis subsidence was assessed through X-ray films.Harris scores system and WOMAC Osteoarthritis Index were recorded before and after operation to evaluate clinical effects of surgery.Results Thirty-eight patients (41 hips) were followed up for 21-36 months,with an average of 31.3 months.The femoral stem subsided 0.68±2.90 mm at the last follow-up.After operation,hip pain of patients was relieved obviously.The Harris score improved from 38.7±12.1 (15-66) preoperatively to 95.2±4.49 (83-100) postoperatively,WOMAC Index from 66.7±12.0 (49-94) to 12.8±5.6 (0-24).During follow-up period,there was no serious complication such as femoral neck fracture,infection of wound,pulmonary embolism,et al.No dislocation,implant prosthesis failure and infection were observed.Conclusion The short stem hip arthroplasty preserves bone stock to a great extent.The short stem implant showed a good stability and osseous integration.The wear rate of ceramic-on-ceramic bearing surface is extremely low.Short stem hip arthroplasty plus ceramic-on-ceramic bearing surface might be a good option for the young and middle-aged patients with femoral head necrosis.
