Objective To analyse 35 cases with failure and malfunction hemodialysis access managed by interventional radiology. Methods 35 cases with failure and malfunction hemodialysis access were examined by angiography and treated by interventional management subseqently. 26 cases of thrombosis occlusilon were treated with thrombolytic therapy and 15 cases of malfunctioning hemodialysis access were done with PTA. Results The initial angiogram showed 9 patients with simple stenosis while 26 patients with thrombosis occlusion, with concurrent stenosis in 13 patients. The rate of immediate recanalization of thrombolysis was 88.4% (23/26). The PTA was successful in 12 cases, 7 of the 13 cases concurrent with stenosis and 8 cases with simple stenosis while the other 3 cases of the 15 cases confronted failure. Follow up was made in 6 patients concurrent with stenosis without further management and 3 patients failure to conduct PTA after thrombolytic therapy. Recanalization occurred in 7 cases within 1 month and then did in all the cases in 3 month. Conclusions Angiography and subsequent interventional management play a critical role in the diagnosis and treatment of failure and malfunction hemodialysis access.

Objective To investigate the multiple factors correlated to femoral head necrosis in patients over 45 years old with femoral neck fractures after closed reduction and cannulated screws fixation.Methods Three hundred patients with femoral neck fracture were admitted from May 1999 to May 2004 and treated by closed reduction and internal fixation with cannulated screws.We analyzed the multiple factors:age,gender,Garden classification,follow-up time,procedure delay,quality of reduction,time of full-weight-loading,fixation removal, and preoperative traction.Multiple correlation factors were analyzed by SPSS10.0 statistic system.Results Complete case records were documented in 99 cases who were followed up for an average of 24.5 months(range,8 to 60 months).Femoral head necrosis occurred in 15 cases(15.2%).Time of femoral head necrosis was 8 to 50 months after operation.The combination of quality of reduction,preoperative traction,age,and age?fixation re- moval was found to have the most significant influence on femoral head necrosis after internal fixation for femoral neck fractures.Conclusions Good reduction is the most important factor correlated to the outcome of a femoral neck fracture.Age is linked to the risk of necrosis but it is relatively insignificant.Preoperative traction in wrong positions can increase the incidence of necrosis.Garden classification is important in predicting femoral head necrosis and is associated with quality of reduction,but it is not a risk one in the combination of multiple correlation factors that lead to the necrosis.

BACKGROUND: Microarc oxidation (MAO) is a break-through anodyzing technology for forming oxide films on valve metal.Use of this technology allows thick, porous oxide layers to be formed on the surface of pure titanium. Few biocompatibility reports using this treatment have been found.OBJECTIVE: The blood compatibility of a novel surface modified titanium substrata biomaterial using MAO was investigated.DESIGN: Positive and negative control, contrast observation and gold standard control.SETTING: Wuhan Union Hospital.MATERIALS: A healthy male adult New-Zealand rabbit, weighing 2.5 kg and ordinary grade, was selected in this study.Pure titanium sticks TA1 (Baoji Yingnaite Non-ferrous Metal Co., Ltd.), MAO-Ti and 20 g/L potassium oxalate were also selected in this study.METHODS: The study was carried out in the Laboratory of General Surgery, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology in May 2006. ① Materials: Titanium substrate of 10 mm in diameter and 2 mm in depth was put in an electrolyte which was quipped with deionized water, dibasic sodium phosphate, and ethanoic acid calcium for MAO treatment for 10 minutes. ② Groups: Three groups were analysed: test group, negative control group and positive control group. Test group: MAO-Ti was dipped in 10 mL saline; Positive control group: 10 mL deionized water was added in each tube; Negative control group: 10 mL saline was added in each tube. ③ Operation: Fresh whole blood was collected from rabbit and then mixed with the liquids in the three groups respectively after anti-coagulation. In addition, UV-Visible Spectrophotometer was used to evaluate the hemolytic ratio. A hemolytic ratio below or equal to 5% indicated that this novel material fitted the requirements. On the contrary, a hemolytic ratio higher than 5% proofed the existence of a hemolyzation.MAIN OUTCOME MEASURES: The hemolytic ratio of materials in three groups.RESULTS: The hemolytic ratio of the test group was 0.90%. The result indicated that this new material had no haemolysis effect.CONCLUSION: The material does not resolve red blood cells and is coincident with the international and governmental standard.

OBJECTIVETo investigate the anxiety disorders and influence factors that occur in adolescent patients with cleft lip and palate and to provide theoretical foundation for mental intervention.

METHODSA total of 120 adolescent patients with cleft lip and palate were investigated using a general information questionnaire, the self-rating anxiety scale, and the social support rating scale (SSRS). The influence factors of anxiety disorders were analyzed.

RESULTSThe effective questionnaires were 119. The occurrence rate of anxiety disorder in adolescent patients was 49.6% (59/119), and the occurrence rates of mild, moderate, and severe anxieties were 41.2% (49/119), 7.6% (9/119), and 0.8% (1/119), respectively. The gender, residential area, disease category, family status (one child or no children), and incidence rate of anxiety disorder in patients were statistically different (P<0.05). The SSRS scores of patients with anxiety disorder were lower than those of patients without anxiety disorder (P<0.05). Multiple regression analysis showed that gender and social support were predictive factors of the occurrence of anxiety disorder (R=0.318).

CONCLUSIONA high anxiety disorder rate occurred in adolescent patients with cleft lip and palate. dender and social support were important influencing factors for anxiety disorder. In the after-mental intervention, considerable attention should be given to the anxiety disorders of patients and improve their mental health.
