Objective To establish the technique of hyperinsulinemic euglycemic clamp and to study the reference value of insulin sensitivity index in healthy Chinese. Methods According to the feedback mathematical model developed by DeFronzo, the technique of hyperinsulinemic euglycemic clamp was used in 90 healthy Chi- nese [ male:female =71 = 19; age; (28. 3±6. 1) years; body mass index (20. 9±1.5) kg/m2 ] to study die glu-cose metabolized rate. Blood samples were obtained at timed intervals in the fasting state and during the clamp for the measurement of glucose, insulin and C peptide. Results During the clamp tests, the blood glucose levels were con-trolled within 10% of target value. The coefficient of variation of glucose levels was 3. 8% 0.1%. In the steady state, the insulin sensitivity index (glucose metabolized rate, M value ) was (7.78±2.30) mg· kg-1 min-1, which was distributed normally. The lowest quartile of M value was 6. 286 mg·kg -1 min-1'. The coefficient of variation of M value was 9.4%±2.8%. Conclusion The technique of hyperinsulinemic euglycemic clamp and the reference value of insulin sensitivity index in healthy Chinese are successfully established in our center.

OBJECTIVETo research the preparation technology and dissolution of Blumea volatile oil suppository.

METHODIn order to establish the content determination and methodology inspection method of Blumea volatile oil plug, the extraction process of Blumea volatile oil was optimized by using orthogonal test. Optimization on the investigation to the suppository matrix by melting time, appearance and dissolution was carried on. The best prescription craft was determined by determining the best molding temperature, dosage of the matrix and complementary makings. The determination method of dissolution was established by investigating different dissolution method and its impact on the preparation of dissolution.

RESULTThe best conditions of steam distillation extracted Blumea volatile oil was as followed, the ratio of gardenia to liquor 1:6, 2.5% drug amount of sodium, 8 hours of extracting time. The optimum temperature for mold was 60-65 degrees C. Preparation technique of Blumea volatile oil suppository was stable, which after 45 minutes and 3 h in pH 4.5 PBS released at least 70% and 90%.

CONCLUSIONBlumea volatile oil suppository with rational prescription, simple preparation and good stability.

Objective To assess and compare the difference in image quality and exposure dose between single-sided reading image plate(IP)and dual-sided reading IP.Methods A contrast-detail phantom CDRAD 2.0 was exposed by single-sided and dual-sided reading IP with different mAs sets.The entrance surface doses were recorded for all images.Images were then presented to two radiologists on a high resolution monitor of diagnosis workstation.The image quality figure(IQF)was measured for each image. Statistical analysis was performed using Spearman's correlation test and Wilcoxon signed-rank test to compare the difference in image quality and exposure dose between single-sided IP and dual-sided reading IP. Results With different tube current dosage of 5.6,12.0,20.0,25.0,and 40.0 mAs,IQF values of single-sided reading IP were 47.95,37.68,34.31,28.61,and 24.65,respectively,while those of dual- sided reading IP were 38.83,29.81,29.65,25.16,and 21.43,respectively.The IQF difference between them showed statistical significance(P

Objective Explore a new method which application absorbable suture netting for chest wall reconstruction and observe the clinical effect.Methods For 23 cases of part of the rib resection,support the soft tissue using absorbable suture netting and observe the postoperative results.Results 23 patients have the postoperative respiratory stability and no abnormal breathing and chest wall collapse happened.And this method has a good effect to support the Chest wall.Conclusion Chest wall reconstruction using absorbable suture netting has the following advantages:easily obtained,easy to learn to promote,low prices and postoperative respiratory stability.We believe this method is a new technology deserved to be promoted in our country.

As one of the primary prevention measures to reduce birth defects , the premarital healthcare service has played an important role in the prevention of communicable diseases , maintaining the harmonious and happy mar-riage, health and other aspects of protection of the next generation .Different countries and regions also design and implement the premarital medical examination system based on their actual situations .This article summarized the practices, characteristics and experiences of premarital healthcare services in some foreign countries and regions through several aspects including model , set projects content , financing and other aspects of the application of the premarital results.Finally, this paper put forwards suggestions on the premarital healthcare services in our country to help healthy the carrying out of the premarital work .

BACKGROUNDSurgical treatments for chronic suppurative and cholesteatoma otitis media have been discussed for several decades, but recurrences still occur because of the complex dissection required and hidden lesions associated with otomastoiditis. This study investigated the technology and strategy behind the use of otoendoscopic-assisted otosurgery.

METHODSWe reported on hidden lesions in 32 ears of patients with otomastoiditis between November 2006 and January 2009. All the patients were treated with the aid of an otoendoscope. The advantages of otoendoscopy, including multi-angle light scattering, aperture illumination, and magnification of the local operative field, were utilized in otologic microsurgery, and otoendoscopic operative techniques were introduced for operative sites such as the epitympanum, aditus of the antrum, facial recess, sinus tympani and the mastoid tip.

RESULTSAll patients were followed up from 3 months to 2 years after surgery. All patients recovered well within 3 months following surgery, except for one case of epithelialization of the mastoid cavity occurring 6 months after surgery for cholesteatoma on the cerebellar surface and another case with Bezold's abscess, hyperplastic granulation tissue developed at the antrum.

CONCLUSIONSOtoendoscopy can overcome the technical deficiency of rectilinearity of the visual axis associated with otomicroscopic illumination, which presents a problem when dealing with otomastoiditis lesions in hidden areas. This technique allows such lesions within the complex three-dimensional structure to be visualized and cleaned. Otoendoscopy thus has significant potential for improving the quality of surgery and reducing the risk of postoperative recurrence.
