Objective To explore the effect of uric acid (UA) on the rat glomerular mesangial cells (GMCs) and its possible mechanism in vitro. Methods Cultured rat GMCs were treated with various concentrations of UA (50 μmol/L, 100 μmol/L, 300 μmol/L) in the presence or absence of U0126, apocynin, rotenone. The incorporation of 3H-thymidine (3H-TdR) and cell counting were used to measure GMCs proliferation. GMCs cell-cycle was analyzed by flow cytometry. CyclinD1 and cyclin A2 expression were determined by real-time PCR and Western blotting analysis. ERK1/2 phosphorylation was detected by Western blotting. Reactive oxygen species (ROS) was measured by 2, 7-dichlorofluorescein diacetate (DCFDA) fluorescence. Results (1) Uric acid increased GMCs proliferation in dose-dependent manner compared with the control groups, as assessed by 3H-TdR incorporation and cell counting. GMCs proliferation induced by 300 μmol/L uric acid was increased by more than 1.5-fold assessed by both of the methods. (2) Uric acid decreased cell number in G1/G0 phase and increased cell number in S phase in dosedependent manner, as assessed by flow cytometry. (3) Uric acid iuduced cyclin D1 and cyclin A2 expression in dose-dependent manner. (4)Uric acid increased pospho-ERK1/2 in dose-dependent manner and ERK1/2 specific inhibitor U0126 could suppress uric acid-induced cell proliferation.The inhibition percentage of U0126 was 22% and 31% assassed by cell counting and 3H-TdR incorporation, respectively. (5) Uric acid increased ROS production in dose-dependent manner.NADPH oxidase inhibitor apocynin could also significantly inhibit uric acid-induced ROS production, ERK phosphorylation and cell proliferation. In contrast, rotenone had no effect on them.Conclusion Uric acid can stimulate rat GMCs proliferation, partially by the activation of ERK pathway via NADPH oxidase-derived ROS generation.

OBJECTIVETo analyze the causes of delayed union or nonunion of the ulna after intramedullary nailing in pediatric forearm fractures.
METHODSFrom February 2005 to February 2010,5 patients with forearm fractures who were treated with titanium elastic nailing (TEN) were identified to fulfill the criteria of having developed a delayed union or nonunion of the ulna. The causes of delayed union or nonunion were investigated according to mechanism of injury, fracture location, treatments methods and postoperative management. All patients were male and the age was 3 to 14 years old with an average of 9.4 years. All fractures were located on the mid-third part of forearm. Two cases had a re-fracture. Among them, 3 cases caused by high-energy injury and 2 cases by falling down. Open reduction were performed in 4 cases while the other one was treated with closed reduction. Four patients were immobilized in an above-elbow cast, postoperatively.
RESULTSAll patients were followed up from 7 to 19 months with an average of 11.4 months. There were 4 delayed union and 1 nonunion. Three patients healed after the removal of the nail and avoidance of weight-bearing. Two patients healed by replacing another fixation. No patients had soft-tissue irritation or nail-entry-site infections.. The clinical effect was evaluated according to Daruwalla and Price scores with 3 excellent and 2 good of the results.
CONCLUSIONSUsing titanium elastic nailing for the treatment of pediatric both-bone forearm fractures is a good method. However,strict indication selection should be followed to avoid delayed union or nonunion.

In this paper, a syntactic pattern recognition method of the detection of pulse wave's characteristic information is introduced. According to it, the pressure signal of pulse is measured by non-invasive diagnostic method. Then, the elementary abstracting system transfers it into an input pattern. The recognizer, constructed by Earley algorithm, recognizes the pulse wave's pattern. On the base of it, the pulse wave's characteristic information can be got. Thus, the expert system will make a diagnosis with the information. The experiment result shows that, the new method is of anti-interference, preciseness and intelligence, and it provides an advanced, practical and intelligent means for the pulse diagnostic system.

Objective To investigate the therapeutic effect of VSD combined with external fixator in the treatment of open tibial and fibular fractures in Tibet plateau. Methods From August 2014 to August 2015, totally 16 cases of open tibial and fibular fractures were treated in our department, including 12 males and 4 females with an average 39. 4 years-old. There were 4 cases of proximal and mid tibial fractures while 12 cases were distal fractures. Debridement, vacuum sealing drainage combined with external fixator for stabilization of fractures was performed in all patients after general condition was improved. A vacuum sealing drainage change or second stage wound closure or soft tissue coverage was undergone after 7 days. Bone union time by X-ray and complications were recorded. Results All wounds were healed by second stage. Twelve patients months were followed up ( by calling back to the hospital ) for an average 18 months ( 12 to 24 months ) , 4 cases were lost to follow-up. X-ray demonstrated that bone union was obtained at a mean 5. 5th month (3 to 7 months). There were 9 cases (75%) obtained a first phase of fracture healing, while 3 cases ( 25%) of delayed healing. Pin-track infection was occurred in two patients and was cured by conservative treatment. No complications of deep infection, graft skin or flap necrosis, malunion, nonunion or osteomyelitis was seen during follow-up. Conclusions Vacuum sealing drainage combined with external fixator for treatment of open tibial and fibular fracture in Tibet can rapidly and effectively stabilize the fracture, and simultaneously safely and effectively seal the wound, reduce the wound healing time, promote fracture healing and lower the complication rates.
