Riedel thyroiditis is a benign disease, which is often self-limited. Examinations, such as CT and histologic diagnosis can distinguish it from malignant neoplasms and hashimoto's thyroiditis. Riedel thyroiditis is an uncommon form of chronic thyroiditis in which the thyroid gland is replaced by fibrous tissue. It can be cured by surgery and medicine.

Starting from the transformation of the management models of foreign affairs,we introduced the achievements made through expanding the functions of foreign affairs at a military medical university in terms of academic exchanges,research collaboration,and training of young intellectuals,which resulted in the improvement of scientific and technological strength.Further expansion of foreign affair functions was then discussed in aspects of establishing institutional mechanisms,improving the service platform and building a team of qualified foreign affair administrators.

Objectives To establish an evaluation index system for general hospital's sustainable innovation ability of science and technoloby and determine the index weight. Methods Firstly, the theory of scientific and technological innovation was discussed based on the systematic analysis of the related facts from the documents. Secondly, a set of targets was drafted with methods of work breakdown structure (WBS), classification and combination from references to many other studies of science and technology evaluation, and then revised by experts who are familiar with the subject. Thirdly, the weight of each target was decided through Analytical Hierarchy Process (AHP) and questionnaires. Results A systematic and comprehensive evaluation system of the general hospital's sustainable innovation ability of science and technology, comprised 3 first-level indicators, 15 second-level indicators and 37 third-level indicators, which were proved reliable by consistency check. The weights of each indicator were also defined. Conclusions The evaluation system comprises both qualitative and quantitative indicators. The indicators not only reflect the performance of a period, but also reflect the sustainability of large general hospitals' scientific and technological innovation ability. By using the scientific consultation, analysis and statistics, the evaluation system is proved to be valid and reliable.

Objective To evaluate the sustainable innovative ability of science and technology (S &T) of four large general hospitals from three different regions of China(Chongqing, Shaanxi and Hunan) with an evaluation system. Method The data collected were processed with normalization method. The evaluation models were established and varied in design to reflect either the dynamic trends or the levels of innovative abilities in different hospitals. Results Hospital A, B and D took on an ascending trend in sustainable S & T ability for innovation, while hospital C showed a descending trend in recent years. Overall, hospital A and D had a stronger sustainable S & T ability for innovation than hospital B and C. Conclusion The eval-uation system established is able to reflect the levels and trends of sustainable S & T innovative ability of the selected hospitals, which is in accordance with the actual situations, and is therefore scientific and feasible.It could provide reference for hospital S & T administrators to make decisions and is favorable to the sustainable development of hospital's S & T innovative ability.

Objective To discuss the effect of different intension electrotherapy to rabbits'FERG,Methods Using the FERG as the target,to stimulate the TAIXI point with 0.2,0.8,2.0 and 4.0mA inrension eleetrotherapy,then observe the change of the rabbits'FERG during and after the stimulation.Results 0.8mA intension can lead to the delay of the FERG a-wave's latency obviously.The lower or higher.stimulation has little effect to the awave's latency.All kinds of stimulation to the b-wave's latency has little difference,but the effect to the amplitude has significant difference.While the stimulating intension below 2mA in 15 minutes,the b-wave's amplitude rise obviously with the intension's rising,but the amplitude will fall when the intension get to 4mA.Conclusion The effect of electrotherapy on the retina'function has osculation relationship with the electrotherapy intenmon,the best effect needs the most fitful intension of stimulation.

AIM　To study the structures of the epimerides of cycloclausenamide. METHODS　The structures of compound I, extracted from Clausena lansium (Lour.) Skeels, and synthesized compound III were determined by single crystal X-ray diffraction analysis. The stereo-structures of compound II and IV were also built up through Tripos force field based on crystal structures of compound I and III. RESULTS　The molecular formula and molecular weight were found to be C18H17O2N and 279.34 respectively. Compound I crystallized in monoclinic system, space group P21 with a=0.5928(1), b=1.5014(1), c=1.6190(1) nm, V=1.4410(3) nm3, Z=4, Dx=1.288 g*cm-3, Rf=0.075, Rw=0.073(w=1/σ2｜F｜), S=3.983; compound III crystallized in triclinic system, space group P1 with a=0.5667(1), b=1.2934(1), c=2.1119(1) nm, α=102.17(1), β=90.25(1), γ=102.65(2)°, V=1.4770(5) nm3, Z=4, Dx=1.224 g*cm-3, Rf=0.047, Rw=0.051(w=1/σ2｜F｜), S=0.467. CONCLUSION　These results showed that compound I and III both are cycloclausenamide except that the directions of the phenyl group on C6 are different. Cycloclausenamide can form 4 pairs of epimerides but the directions of the phenyl group does not affect their energy in free state.

In this study we deliberated over the principles and methods and then took the noninvasive continuous measurement of blood glucose concentration through the skin of rabbits. The glucose oxidase sensor was made by covalent immobilization. The best making method of sensor and stable working condition were sifted. Ten female and 10 male adult white rabbits were allocated into the groups of the ante-ultrasound and post-ultrasound, the injection of glucose, and the high and low frequency ultrasounds. After the skin surface was treated by high or low frenquency ultrasound for 5 minutes on the rabbits, obvious changes (P < 0.01) of post-ultrasound and post-injection of glucose were observed by means of glucose oxidase sensor and microcurrent apparatus. After application of ultrasound to the skin of rabbits, the penetration of glucose through the rabbit skin increased obviously. The change of microcurrent signal that was exchanged by the glucose sensor correlated positively with the concentration of glucose of rabbit body. The blood glucose can be tested by the glucose sensor on the skin surface of living animal.

OBJECTIVE: To investigate incidents and clinical features of auditory neuropathy in Nanjing deaf school students. METHOD: Three hundred and fifty-eight deaf students in the school accepted the first examination including otoscopic examination, tympanometry and transiently evoked otoacoustic emissions (TEOAE) screening. Detailed audiological and vestibular evaluations including pure-tone audiometry, immittance audiometry and acoustic reflex measures, transiently evoked otoacoustic emissions (TEOAE), distortion product otoacoustic emissions (DPOAE), auditory brain stem response (ABR), electronystagmography (ENG) and vestibular evoked myogenic potential (VEMP) were given to whom had positive TEOAE screening. RESULT: Three hundred and twenty-three students entered the program of screening for auditory neuropathy. One student had positive TEOAE in single ear while the other two had positive TEOAE in both ears. In the screening stage,there were strong evidences in these three students with auditory neuropathy in the detailed audiological procedures. CONCLUSION Auditory neuropathy, which can also be found in deaf schools, is not as rare as we thought before. Early identification and intervention may help those children to avoid entering the deaf school and to return to normal society.
