Objective To enable medical institutions and personnel in the case of a medical encroachment dispute to provide precise proof in court, use standard format for the legal complaint, employ the appropriate proofgathermg method, ensure the simplicity of the proof-providing procedure, and avoid the waste of manpower and material resources and the liability of economic compensations in the course of compromise settlement, mediation by the health administrative department or adjudication by the court. Methods Regulations were laid down within the hospital for proof-providing procedures, methods, contents, the contents and format of legal complaints and reply letters, and documents in preparation for the provision of proof. Results Through the handling of over 900 medical encroachment disputes, the above methods proved to be practical, applicable and up to the standard. They could save the time of the hospital, the patient and the lawyer on blind surveys, reduce proof-providing time, and improve efficiency in handling medical encroachment disputes. Conclusion Standardizing proof-providing procedures, methods, and contents and the format of legal complaints or reply letters is of great significance in improving efficiency in handling medical encroachment disputes and reducing the hospital's chances of losing lawsuits.

Objective To remedy the general defects of external fixator such as poor stability,complexed operation,strong stress shielding and bad extension function. Methods A total of 102 patients with limb shaft fracture were treated with the self-made external fixation and the curative effect observed. There were 84 males and 18 females aged at 5-78 years. Of all, 76 cases had tibial and fibular fractures, 10 femoral shaft fractures (children), 4 intertrochanteric or subtrochanteric fractures, 7 ulnar or radial fractures and 5 humeral shaft fractures. Results All patients got good results through a all-course observation, among which 76 cases with tibial and fibular fractures were followed up for 3 months to one year. Furthermore, the mean substantial bone healing time was only 3.5 months. The joint functions of the knee and the ankle recovered synchronously, with an overall excellence rate of 93.4%. No displacement of the fractured part or further fracture occurred. Conclusions The structure and function of the self-made external fixation accord with the demanding of current external fixator in orthopaedics.

The baculoviral inhibitors of apoptosis play a significant role in infectivity and viral host-range, which make them potential candidates for the engineering and improvement of baculovirus insecticidal. The iap3 gene of Spodoptera exigua nucleopolyhedrovirus (SeMNPV), amplified by PCR, was 939 bp encoding IAP3. The PCR product was cloned into EcoR I/Bam H I of the plasmid pEGFP-C1. GFP was fused to the N-terminaus of IAP3 to study distribution in HEK293. It was observed that the plasmid expressing IAP3 significantly inhibited apoptosis induced by cisplatin in HEK293 cells. We conclude that the IAP3 of SeMNPV is functional in mammalian cells.

Objective To investigate the effect of insulin combined with Edaravone therapy on delayed cerebral vasospasm (CVS) after experimental subarachnoid hemorrhage (SAH).Methods 40 New Zealand white rabbits were randomly separated into sham-operated group (n=8),SAH group (n=10),insulin group (n=10) and insulin+Edaravone group(n=12).SAH models were made by injecting blood twice into cisterna magna.30 min later of the first blood injected,the insulin 0.2 U/kg was subcutaneous injected in insulin group and insulin+Edaravone group,3 times daily for 7 d;while,the insulin+Edaravone group received Edaravone 0.5 mg/kg (intravenous injected in ear vein) twice a day for 7 d.7 d after the model made,the basilar artery cross sectional area was measured and the pathological changes were obseved to estimate the degree of CVS.The expression of insulin receptor(InRa) in vascular endothelial cell was detected by immunohistochemical staining.Results The basilar artery cross sectional area between insulin+Edaravone group[(0.46?0.3)mm2]and the sham-operated group[(0.48?0.4)mm2] was no significant difference;but they were obviously bigger than those in SAH group[(0.25?0.3) mm2] and the insulin group [(0.30?0.3)mm2](all P

Objective To investigate the efficacy of peritoneal dialysis(PD) in the children with complex congenital heart disease after surgery.Methods 65 children with complex congenital heart disease were divided into group A(33 cases) and group B(32 cases).Group A was given PD when diuretics or urine output was less than 0.5ml per hour,while group B was given PD when urine output was less than 0.5ml per hour after 6h.The survival effect and indicators of PD before and after treatment were observed.Results The effective rate of group A (84.85% ) was significantly better than group B ( 53.12% ) ( x2 =5.18,P < 0.05 ).The fatality rate of group A (9.09% ) was significantly lower than group B ( 18.75% ) ( x2 =5.32,P < 0.05 ).The renal function was significantly improved.Urine output increased to the normal level,serum potassium,blood urea nitrogen,serum creatinine concentration were effectively controlled,the changes of indicators had significant differences before and after PD (t =5.22,3.46,46,4.89,4.77,all P < 0.05).Conclusion PD was an effective support method for heart,renal insufficiency after the surgery of complex congenital heart disease,and it had good clinical effect for early application.

Objective To study the risk factors and pathogenesis of pulmonary infection in acute stroke patients. Methods A retrospective analysis was taken in 257 acute stroke cases to investigate the incidence of pulmonary infection and its relationship with the underlying disease, disturbance of consciousness, invasive operation,the type of pathogenic bacteria and drug susceptibility. Results The positive rate of pulmonary infection in acute stroke patients was high and related to many factors including severity of stroke, disturbance of consciousness,primary diseases, and invasive examination etc. The most popular infective bacteria were Gram-negative bacteria. The imipenem was most sensitive to Gram-negative and Gram-positive bacteria, followed by Amikacin and piperacillin too. Conclusions The pulmonary infection in cerebral stroke patients is caused by many factors, of which Gramnegative bacteria play the most important role. Identification of the risk factor and pathogenic bacteria is helpful in treating cerebral stroke infectious complications.

Objective:To observe whether nitric oxide (NO) could enhance the damaging effect of cyclophosphamide on L1210 cells cultured in vitro, and to investigate the mechanism of this action. Methods:L1210 cells were co-cultured with 3T3 cells in DMEM medium supplemented with cyclophosphamide (400 ?g/ml). The L1210 cells were divided into three groups based on different transfected 3T3 cells: pcDNA3.0-iNOS plasmid transfected 3T3 cells (Group 1), pcDNA3.0 plasmid transfected 3T3 cells (Group 2), pcDNA3.0-iNOS plasmid transfected 3T3 cells plus DEVD-CHO(Group 3). The viability and apoptosis rate of L1210 cells at different culture periods were determined by trypan blue exclusion and TUNNEL method, respectively. And the cell cycles at G_1 and S phase were detected by flow cytometry. Results:①After cyclophosphamide treatment, the viability of L1210 cells was significantly lower in Group 1 than that in Group 2 during 12-72 h (P

Objective To examine the clinical factors associated with postoperative outcome in dementia combined with cerebral amyloid angiopathy-related intracerebral hemorrhage (CAA-ICH). Methods The clinical data of 25 surgical patients of dementia combined with CAA-ICH were retrospectively analyzed. The postoperative short-term effects and long-term effects were evaluated at the 30 d and 6 months after operation according to the modified Rankin score (MRS), and the influencing factors were analyzed. Results Among the 25 patients, eusemia was in 6 cases. Age ≥ 75 years, Glasgow coma score (GCS) ≤ 8 scores on admission, hypertension, postoperative anemia, pulmonary diseases, midline shift were the influencing factors of postoperative short-term effects (P < 0.05 or <0.01). Twenty-two patients were followed up for 6 months, and ensemia was in 9 cases. Age≥75 years, GCS ≤ 8 scores on admission, hypertension, postoperative anemia, hypoproteinemia and pulmonary diseases were the influencing factors of postoperative long-term effects (P<0.01 or<0.05). Conclusions Preoperative assessment is important for the patients of dementia combined with CAA-ICH. Age ≥ 75 years, GCS ≤ 8 socres on admission, hypertension, postoperative anemia, pulmonary diseases, midline shift are associated with poor short-term effects; age ≥ 75 years, GCS ≤ 8 scores on admission,hypertension, postoperative anemia, hypoproteinemia and pulmonary diseases are associated with poor long-term effects.
