Objective To summarize our experience in percutaneous transluminal angioplasty(PTA) in the management of thoracoabdominal aortic stenosis of Takayasu's arteritis. Methods From 1987～2001, 12 patients of Takayasu's arteritis with thoracoabdominal aortic stenosis underwent PTA. Aortography and pressure of stenotic segment of arota before and after angioplasty were used to evaluate efficacy. Color Doppler ultrasound examination and Doppler segmental pressure measurement were used in follow-up. Results Success was achieved in all cases without mortality and serious complications except for 1 case of acute thrombosis of iliofemoral artery. The residual stenosis were less than 50% in all cases and the pressure gradient was 5 0mmHg～10 5 mmHg with average pressure being 7 2 mmHg after angioplasty ,although they were 25mmHg～46 mmHg averaging of 37 7 mmHg before angioplasty. All cases were followed up for 9(12～72) months and the result was good without lumen restenosis and obstruction. Conclusions PTA is the first choice for Takayasu's arteritis of thoracoabdominal aortic stenosis of local size and proved to be safe, effectiveand economical. It is also effective for long size cases. It is not necessary to dilate aorta stenosis to normal size, and reducing pressure gradient effectively is enough.

Gold nanostructures with unique optical and photo-thermal properties based on their size and shape have wide applica-tion potential in tumor diagnosis, imaging, photo-thermal therapy, and drug delivery because of surface plasmon resonance. The optical properties of gold nanomaterials allow its use for dark field imaging, optical coherence tomography, and two-photon imaging. Gold nanomaterials can also be used as carriers for a variety of fluorescent molecules and drugs, achieving multifunctional imaging, chemo-therapy, photodynamic therapy, and so on. Photon-electron and electron-electron interactions of gold nanomaterials, which are excited by near-infrared laser, will generate heat that can be used for tumor photothermal therapy. This phenomenon promotes drug release, and photoacoustic imaging. The combined application of hyperthermia and chemotherapy based on gold nanoparticles is effective in opti-mizing the efficacy of cancer treatments. Therefore, gold nanoparticles can integrate multiple functions into one single system and real-ize the integration of tumor diagnosis and therapy, which provide new insights for the on-demand therapy and personalized medicine de-velopment. This study reviews the recent progress of several gold nanoparticles in the integrated applications for tumor theranostics, in-cluding gold nanoshells, gold nanorods, hollow gold nanospheres, gold nanocages, and gold nanostars. The major strategies of gold nanomaterials in biomedical applications are also discussed.

Purpose To investigate the expression of pFRK protein in non-small cell lung cancer (NSCLC) patients and to explore its prognostic value.Methods The expression of p-FRK protein in tumor tissues and corresponding adjacent normal pulmonary tissues from 162 NSCLC patients was detected by immunohistochemistry of EnVision two-step.The correlation among p-FRK expression,age,gender,clinicopathologic features,pTNM stage and metastasis of NSCLC patients was also analyzed.whether p-FRK could be used as an independent predictor of prognosis for patients with NSCLC was further determined.Results The positive expression rate of p-FRK in NSCLC tissues (51.9％) was significantly higher than that of adjacent normal lung tissues (11.7％) (P =0.001).The expression of p-FRK in NSCLC was significantly correlated with histopathologic type,lymph node status and pTNM stage (P ＜0.05).Kaplan-Meier survival analysis showed that there was a negative correlation between p-FRK positive rate and postoperative overall survival (x2 =17.849,P ＜0.001).Multivariate analysis showed that p-FRK expression was an independent prognostic factor for overall survival of NSCLC patients (HR =0.496,95％ CI:0.295-0.836,P ＜ 0.05).Conclusion As a novel NSCLC biomarker,the expression of p-FRK may predict a poor prognosis in the patients with NSCLC.

BACKGROUND: Chronic musculoskeletal pain can cause disability and decreased quality of life of patients. Probing into the therapeutic methods of musculoskeletal disease and choosing proper treatment drugs are important for patients.OBJECTIVE: To evaluate the efficacy and tolerance of controlled-release tramadol in patients with moderate to severe chronic pain of musculoskeletal origin.DESIGN: A self-control study was conducted.SETTING: Arthrtosis Institute, People' s Hospital Affiliated to Peking University.PARTICIPANTS: Patients who were in the Orthopaedic Outpatient Service,People' s Hospital of Peking University were involved. This observational study was conducted in 40 adults who experienced moderate to moderately severe chronic musculoskeletal pain that was not controlled by routine nonsteroidal anti-inflammatory drugs(NSAID) therapy.INTERVENTIONS: Any NSAIDs and other analgesics were prohibited. Patients initially took 50 mg of controlled-release tramadol (Tramcontin) every 12hours, supplemented by every 50 mg if insufficient pain relieved. Recommended daily maximum dose was 400 mg per day. The observation lasted for 4 weeks. The patients were asked for document therapy-relevant data every day and were interviewed every week to doctor assessment.MAIN OUTCOME MEASURES: Pain intensity before and after treatment, pain remission degree, all side effects and their severity.RESULTS: All cases were finished the study and no one withdrew from follow-up. No eligible patients exited from the study because of therapeutic failure or intolerance. In comparison with the initial visual analogue scale (VAS) mean value 6. 80 ± 1.84, the average VAS value at the end of observation was 1.00 ± 1.46, which had significant difference( P ＜ 0. 001) . An average pain reduction of (85. 50±5.35)%was obtained, among which 78% were absolutely and obviously lessened. Side effects were reported in 9cases (22%).Drowsiness and dizziness(6 cases) was the most common, followed by nausea (3 cases), vomiting (1 case), somnolence (2 cases), constipation and urinary retention (1 case) and blurred vision (1 case).CONCLUSION: Tramcontin, as slow-release tramadol, proved to be an effective, safe, and easy-to-use central acting analgesic has an important role in the management of chronic musculoskeletal pain. Light side effect and good tolerance has provided a new choice for treatment of chronic pain in the orthopaedic department.

Objective To assess the efficiency,safety and indications of permanent inferior vena cava filters (VCF) placement for prevention of pulmonary embolism in cases of deep vein thrombosis (DVT). Method In this study 71 cases were treated with permanent inferior vena cava filters by way of the internal jugular vein and the common femoral vein. Cavography was performed routinely before inserting the VCF to confirm no thrombosis in IVC and access veins. The insertion site for filters is the subrenal vena cava. Results The procedure was successful in all cases. There was no case of symptomatic PE occurred during 1～41 months of follow-up. There were 2 cases of IVC thrombosis at the site of insertion and 5 cases of filter tilting less than 15?. There were no other complications. Conclusion Permanent IVC filter placement is an effective method for preventing fatal PE due to DVT. Imaging of the vena cava and access vein by venous ultrasound and cavography, strict anticoagulation therapy after VCF insertion are key to perform VCF placement, provide protection from recurrent life-threatening PE and reduce complications. The filter placement indications should be strict.

[ABSTRACT]OBJECTIVETo explore the method on reconstruction of long and special tracheal defects which can mostly match with natural airway: pedicle rib cartilage with cilia endothelial wall.METHODS8 experimental model of rabbits were trained with cervical double belt blood supply fascia embedding and autologous costal cartilage and nasal septum mucos in the first period, then followed by transplantation in the second period. After the operation, we would assess the physiology, breathing and histopathology index of the rabbits, etc. After the animal experiment, we tried to apply the method to an appropriate clinical case.RESULTS8 cases of experimental rabbits dead after the second period operation with the average survival time of 21.9 days and caused by asphyxia. Histopathological results: rib cartilage and trachea ring up of cartilage cells and fibers have high similarity in histology; cartilage of all cases under the cultivation of the pedicle fascial package has not been absorbed; all cases' nasal septum mucosa in the body and blood supply to differentiation under fascia nutrition. Then we applied the method on a clinical case.CONCLUSIONTrachea ring rib cartilage had a higher similarity to the tracheal cartilage on the histology and biological characteristics that can be used as the preparation of artificial trachea shaping material or cell culture to tissue engineering materials. Package of rib cartilage pedicle fascial can provide adequate blood supply to make up for a free training rib cartilage defect to its absorption. Nasal septum mucosa of pressure in the body and blood supply of the fascia nutrition can simulate the trachea ciliated epithelium, which can play its biological characteristics similar to the inner wall of the trachea.
