Objective To investigate the pharmacologic action of the Magnolia biondii Pamp volatile oil nanometer bangosome. MethodsThe pharmacologic action of the Magnolia biondii Pamp volatile oil nanometer bangosome was evaluated by observing its effect on Jimpy mice with swelling ear,capillary permeability and rats with allergic symptoms. Results The Magnolia biondii Pamp volatile oil nanometer bangosome could significantly relieve the degree of swelling in Jimpy mice extended by p-xylene,inhibit the increased capillary permeability in Jimpy mice extended by HAC,and combat the symptoms of rhinocnesmus,sneezing,nasal discharge with a better effect than the Magnolia biondii Pamp volatile oil. Conclusion The Magnolia biondii Pamp Volatile oil nanometer bangosome has a good anti-inflammation and anti-hypersensitiveness effect,which upgrades the effect of the Magnolia biondii Pamp volatile oil.

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.

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.

Objective To assess the efficacy and clinical resuhs of thoracic endovascular aortic repair (TEVAR) in Stanford type B aortic dissection,and to explore the therapentic strategy and prevention of complication.Methods Fifty-eight patients with Stanford type B aortic dissection underwent TEVAR were enrolled,and were followed up regularly.Results The technical feasibility and success with deployment proximal to the entry tear was 100.0%(58/58),requiring partial coverage of the left subclavian artery in 20 patients and total coverage in 4 patients,and 2 patients used chimney stents.Hospital mortality was 5.2% (3/58).Type Ⅰ endoleak was found in 11 patients (19.0%,11/58).In 55 survival patients,48 patients occurred thrombosis in pseudocoele and 2 patients' endoleak disappeared.Seven patients' endoleak appeared blood flow.Forty-eight patients(87.3 %,48/55) were followed up for 3-68 months.Two patients died,and 2 patients' endoleak disappeared,with total suberization in pseudocoele.Other 5 patients' endoleak relieved,with partial suberization in pseudocoele.One patient had new intimal tear at the distal end of the stent-graft and required a second stent implantation.Conclusion TEVAR is safe and effective for the treatment of Stanford type B aortic dissection.

Objective To determine the normal reference values for thromboelastography (TEG) in Chinese healthy elderly people in Beijing and compare them with those provided by the manufacturer and with people under the age of 55 years.Methods The healthy elderly people aged over 65 years were enrolled from March 2014 to April 2014.4 ml of peripheral vein blood samples were taken from each person.All subjects underwent the laboratory tests of prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT) and fibrinogen (FIB).TEG parameters including reaction time (R),coagulation time (K),angle (alpha) and maximum amplitude (MA) were determined by using a Heamoscope 5000 device.Results A total of 119 healthy elderly subjects were enrolled in this study.The mean values (95% CI) of TEG parameters for them were R:6.29 min (4.4-8.2 min),K:1.63 min (0.8-2.5 min),α-Angle:66.09° (55.0-77.1°),MA:63.43mm (54.5-72.3 mm).There were significant differences in the values of R,K and α-Angle between the elderly and non-elderly groups (P<0.001 or 0.05).There were significant differences in the values of K,α-Angle and MA between males and females (P<0.05 or 0.001).According to the normal reference values provided by the manufacturer,16.1% (19/119) of the healthy elderly volunteers had at least one abnormal parameter beyond its normal range.3% (3/119) of the healthy elderly people were diagnosed as coagulation abnormalities,yielding a specificity of 84%.Compared with normal reference values provided by the manufacturer,the value of R was lower and the value of MA was higher in the healthy elderly people in Beijing.Conclusions The normal reference values for TEG should be established based on the local population characteristics.
