Objective To investigate the treatment of complicated upper urinary tract calculi. Methods 138 cases of upper urinary tract calculi were treated by the combination of extracorporeal shork wave lithotripsy (ESWL),ureteroscopic lithotripsy and minimally invasive percutaneous nephrolithotomy were reviewed.There were 110 cases of complex ureteral stone and 28 cases of complex kidney stone among the group.All cases had variable degree of hydronephrosis.The treatment program for complex upper urinary tract calculi was initially,ESWL and followed by ureteroscopy and pneumatic lithotripsy in 24 hours.For the complex kidney stone and upper ureteral stone,which was difficult for ureteroscopy lithotripsy.The program was firstly percutuneous minimal pyelostomy,ESWL after 5~7 days,then urteroscopy lithotripsy and lithotomy through the fistula in 24 hours. Results Total stone-free rate was 97.1%(134/138),in ureteral stone group was 100%(110/110),in kidney stone group 85.7%(24/28).Satisfactory result has been observed in all cases. Conclusions The endoscopic manipulation become easy and fast by means of endoscopic manipulation in the treatment of complex upper urinary tract calculi.This technique is minimally invasive and has less complications,it increases the stone-free rate.

Objective To recognize the factors which influence the therapeutic efficacy of transurethral resection of the prostate (TURP) and to improve the qualities of TURP. Methods The data of 600 patients with benign prostatic hyperplasia (BPH) were retrospectively studied based on the mastering of TURP.The patients’age ranged from 52 to 92 years,with a mean of 64.8 years.Preoperatively,the volume of the prostate was 16.3~210.4 ml,with a mean of 46.2 ml,measured by color Doppler B-ultrasound.The average maximum urinary flow rate (Qmax) was 8.4 ml/s,and average urinary flow rate (Qave) was 4.3 ml/s.The average residual urinary volume (RU) was 75 ml,and the average IPSS was 23. Results TURP was successfully performed on all the 600 patients.The average resected prostate tissue weight was 31.8 g.The average electric ablation time was 51 minutes.Intraoperative blood transfusion was performed in 38 cases. Aura of transurethral resection syndrome (TURS) occurred in 4 cases,but no TURS occurred.Of the 600 cases,508 cases (85%) were followed up for 1~32 months.Postoperative average Qmax increased to 16.9 ml/s,Qave increased to 10.8 ml/s and RU decreased to 15 ml.Compared with those of preoperation,the differences were statistically significant (P

BACKGROUND: Recent studies have shown that induced pluripotent stem cells (iPSCs) could be differentiated into mesenchymal stem cells (MSCs) with notable advantages over iPSCs per se. In order to promote the application of iPSC-MSCs for osteoregenerative medicine, the present study aimed to assess the ability of murine iPSC-MSCs to differentiate into osteoblast phenotype. METHODS: Osteogenic differentiation medium, blending mouse osteoblast-conditioned medium (CM) with basic medium (BM) at ratio 3:7, 5:5 and 7:3, were administered to iPSC-MSCs, respectively. After 14 days, differentiation was evaluated by lineage-specific morphology, histological stain, quantitative reverse transcription-polymerase chain reaction and immunostaining. RESULTS: The osteogenesis-related genes, alp, runx2, col1 and ocn expressions suggest that culture medium consisting of CM:BM at the ratio of 3:7 enhanced the osteogenic differentiation more than other concentrations that were tested. In addition, the alkaline phosphatase activity and osteogenic marker Runx2 expression demonstrate that the combination of CM and BM significantly enhanced the osteogenic differentiation of iPSC-MSCs. CONCLUSION: In summary, this study has shown that osteoblast-derived CM can dramatically enhance osteogenic differentiation of iPSC-MSCs toward osteoblasts. Results from this work will contribute to optimize the osteogenic induction conditions of iPSC-MSCs and will assist in the potential application of iPSC-MSCs for bone tissue engineering.

BACKGROUND:With the increasing of aging, the incidence and mortality of osteoporotic hip fracture wil rise. It is of great significance to study the pathogenesis and preventing method. At present, finite element analysis can be used to judge fracture, only for the distribution trend of fracture failure in the starting point or section view, but it cannot completely reflect actual situation of fracture. OBJECTIVE:To build the fracture model of the femoral neck fracture caused by fal ing-induced external force based on the finite element analysis LS-DYNA software, and to evaluate the effect of rupture. METHODS:CT image data of one case of elderly femoral neck fracture were col ected. Using Mimics software, region growth of the contralateral area, cavity fil ing, editing, rebuilding the contralateral proximal femur model were conducted. Data were imported in Hypermesh and LS-DYNA software for meshing, and defining material properties. The failure parameters and interfacial properties were set. The load and force boundary constraints simulating the fal ing were simulated. The model of femoral neck fracture was calculated. Rupture effect was evaluated. RESULTS AND CONCLUSION:(1) The validity of contralateral proximal femur three-dimensional model was verified. Based on the finite element analysis software LS-DYNA, the femoral neck fracture model matched the actual fracture line to a degree of close to 83%. (2) Above results confirmed that based on the finite element analysis, LS-DYNA software can wel simulate the femoral neck fracture, which provides experimental basis to the exploration of femoral neck fracture classification mechanism caused by different fal ing-induced external forces.

Objective: To analyze the relationship between the serum levels of low density lipoprotein cholesterol (LDL-C) and achilles tendon thickness (ATT).
Methods: We studied 154 patients with high serum level of LDL-C (LDL-C≥3.37 mmol/L) from 2014-03 to 2015-03, the patients were at (18-75) years of age. According to《Guidelines on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults 2007》, the patients were divided into 2 groups:Borderline high LDL-C (3.3-4.12 mmol/L) group n=50 and High LDL-C (≥4.14 mmol/L) group, n=104;in addition, there was a Normal control group (LDL-C<3.37 mmol/L), n=51. ATT values were measured by standard digital radiography and the results were compared among 3 groups;the relationship between serum levels of LDL-C and ATT was studied.
Results: ATT levels in High LDL-C group (9.42 ± 3.63) mm was higher than Borderline high group (8.24±1.73) mm and Normal control group (6.05±0.28)mm, all P<0.05. The liner correlation coefifcient of serum level of LDL-C and the mean ATT was (r=0.346, P<0.001).
Conclusion: Our preliminary research showed that the higher serum level of LDL-C associated with thicker ATT, they had positive correlation. This phenomenon should be further conifrmed by large sample and multi-center investigation.
