Endovascular repair has gained worldwide popularity for the treatment of aortic dissection and aortic aneurysm.The non-tapered stents are selected usually.The aortic diameters vary in different level.High incidence of distal stent-induced complications is closely related to the aortic taper angle.According to several published studies,the aortic taper angle could be evaluated by establishing geometric model.Applications of tapered stents can significantly reducing the incidence of distal stent-induced comnplications.This review summaries the latest researches in the studies of the progress and the application of the aortic taper angle and the tapered stents,providing a reference for endovascular stent-graft selecting in the treatment of aortic dissection and aortic aneurysm.

Objective To assess the clinical value of limited internal fixation combined with hinged super-articular external fixator for the treatment of elbow fracture. Methods 10 patents with elbow fracture were treated with hinged external fixator from March 2001 to November 2002. It involved 8 males and 2 females, aged from 22 to 46 years. There were 4 humeral intercondylar fractures of Riseborough type Ⅳ, the fractures were fixed with few cancellous or interfacial screws through the postero-medial approach, the olecranon and the attached triceps were reflected proximally after the olecranon osteotomy. Among the other 6 severe fracture-dislocations of the elbow, 2 complicated with fracture of the coronoid process; 1 fracture of the Regan type Ⅲ, whose fragments were over 50% of the coronoid process, was fixed with screws; another 1 fracture of the Regan type Ⅱ, whose comminution was less than 50%, was sutured with the joint capsule from proximal to distal part; 2 combined with radial head fracture of Mason type Ⅳ, both selected the lateral elbow approach, 1 with resection because of comminution, the other was fixed nearly the 2/3 of its whole dimension; and 2 with olecranon fracture were fixed with tension-band wire. Results All 10 patients were available at final follow up, the mean duration was 12 months (range, 6-18 months). According to the Morry scoring system, there were 6 excellent, 3 good, 1 fair, and the effective rate was 90%. 8 cases united in the first-stage, the other 2 achieved delayed union because of open fracture. Conclusion The technique of hinged external fixator for the fractures around elbow not only can help to stabilize the fractures but also allows early rehabilitation. In comparison with other methods, it can better improve the function of elbow, so it is an effective treatment for this kind of injury.

OBJECTIVE: To investigate the clinical features and operation treatment of the congenital middle ear cholesteatoma. METHOD: A retrospective review of clinical and surgical records of 10 patients with congenital middle ear cholesteatoma were performed. All patients were treated by surgeries,5 of 10 cases deal with one-stage tympanoplasty after drum exploration by external auditory meatus, 3 cases dealed with closed mastoidotympanectomy and tympanomastoidectomy, 2 cases dealed with open mastoidotympanectomy and tympanomastoidectomy. RESULT: The cholesteatomas were located at or around the posterior tympanum or mesotympanum in 5 patients, confined to the tympanic cavity and attic in 3 patients, advanced cholesteatoma that extended from the tympanic cavity into the mastoid antrum was seen in 2 patients. The mean postoperative PTA was 30 dB HL, the mean ABG was within 20 dB, after six months. No residual or recurrence of cholesteatoma was found. CONCLUSION The congenital cholesteatoma often originates from the posterior or anterior of the middle ear, with hiding lesion, thus result in severe conductive hearing loss. Imaging examination plays an important role in diagnosing and treating of congenital cholesteatoma. Early stage surgical treatment can obtain a good hearing reconstruction effect.

Basal rate verification is the process to find and verify the basal rate of continuous subcutaneous insulin infusion (CSⅡ) required for basal glucose metabolism.In the present study,five cases of brittle diabetes were treated by CSⅡ with Insulin Lispro.After doses were adjusted to reach steady blood glucose levels,basal rate verifying tests were carried out.The results showed that the overall level and stability of blood glucose were improved markedly after CSⅡ.Before and after the verification of the basal rate,there was no significant difference in CSⅡ total doses.Basal rates decreased from 50％ of total to 30％ (P＜0.05),and boluses increased to 70％ (P＜0.05).The basal rates during lunch and supper time were reduced by half (P＜0.05),the boluses of lunch and supper were increased 1.5 times (P＜0.05),and square waves were needed to control postprandial blood glucose.These results suggest that the CSⅡ could smoothly control blood glucose level in brittle diabetes without basal rate verification.However,the implementation of the verification could better determine the basal rates for basal glucose metabolism,and thus help to identify diet-related boluses.

Objective To evaluate effect of en bloc resection of malignant sacral tumor involving partial sacrum and ipsilateral sacroiliac joint with reservation of contralateral sacral foramina.Methods Between February 2005 and July 2010,16 patients with malignant sacral tumor involving partial sacrum and ipsilateral sacroiliac joint underwent hemi-sacrectomy and functional reconstruction.The operation achieved en bloc resection of tumor with reservation of contralateral sacral foramina.There were 10 males and 6 females,aged from 17 to 70 years (average,37.9 years).There were 5 cases of chondrosarcoma,3 cases of Ewing's sarcoma,2 cases of malignant schwannoma,2 cases of osteosarcoma,1 case of malignant giant cell tumor of bone,1 case of lymphoma and 2 cases of metastatic tumor.Results The surgical time ranged from 4 to 11.5 hours (average,6.5 hours).The average blood loss was 3600 ml (range,1500 to 5500 ml).Five patients underwent type Ⅰ resection,while 11 patients underwent type Ⅱ resection.All patients were followed up for 21 to 59 months (average,34.4 months).Three months after operation,13 patients had difficulty with ankle plantar flexion,while sphincter function was more or less reserved in 16 patients.Four patients (25％)had wound healing complications,which was cured after debridement and drainage.Local recurrence occurred in 7 patients.There were 5 cases of local recurrence among 6 patients who had intralesional margin;4 recurrence lesions located in the sacrum and 1 in soft tissue.Eight patients (50.0％) survived without tumor,2 patients (12.5％)survived with tumor,and 6 patients (37.5％) died of tumor.Conclusion The en bloc resection of tumor involving partial sacrum and ipsilateral sacroiliac joint with reservation of contralateral sacral foramina was feasible and had better outcome compared with total sacrectomy.

This paper is to report the development of a rapid and sensitive method for the determination of s-oleylpropanolamide (OPA) in various tissues of rat (brain, heart, lung, liver, spleen, small intestine, kidney, adipose tissue and muscle), and to assess the applicability of the assay to tissue distribution. OPA was extracted by liquid-liquid extraction method with undecylenoylethanolamide as an internal standard. The concentrations of OPA were determined by LC-MS/MS after a single intragastric dose of 50 mg x kg(-1) at 4 time points (5 rats per group). With multiple reactions monitoring mode (MRM) the limit of quantification (LLOQ) was determined at 1 microg x L(-1). The calibration curve was linear from 1 to 2 x 104 microg x L(-1) (r > or = 0.999 0) for tissue homogenates. Validation parameters such as accuracy, precision and recovery were found to be within the acceptance criteria of the assay validation guidelines. The highest concentration was found in small intestine (the highest time point is 15 min) and heart (the highest time point is 90 min). The assay is rapid, sensitive and applicable to studying tissue distribution of OPA in rats.
