Female rats were divided into three groups: 1) LI group, receiving low iodine diet and distilled water; 2) NI group being fed with the same food as LI group and distilled water supplemented with potassium iodide; and 3) N group,taking usual diet and tap water. T4 5'-deiodinase, T, and T4 content in whole brain homogenate and serum T, and T4 level of the young animals delivered by the above-mentioned rats were analyzed. Deiodinase activity was expressed in terms'of T3→T4 conversion rate (CR). The results showed that the average CR in rat brain homogenates of LI group was significantly higher than those of the other two groups, it is 2.73 times of that in N group. There were no significant differences among the three groups in serum T3 concentration and T3 content of brain homogenate. But serum T4 concentration of LI group was only 10.9% of that in N group and brain homogenate T4 level was also lower, being only 38.5% of the latter. It suggested that T4 5'-deiodinase in the immature rat brain is more effective than in adult one on modulating thyroid hormone function in brain. Thus, the increased activity of brain T4 5'-deiodinase may compensate for the decreased T4 pool, maintaining a normal brain T3 content in congenital iodine-deficient rat.

The authors have applied the Omaha system in six different researches conducted in Hong Kong and mainland China in the last ten years. These researches have been conducted using different client groups,specialty nurses,and in the hospital,clinic and community settings. The Omaha system was found to be instrumental in serving as a conceptual framework for study,designing the intervention protocol,identifying clients' health problems,defining nursing interventions and evaluating research outcomes. The Omaha system is a valuable tool for research and practice and is worth exploring further for its application in mainland China,particularly in the areas of community nursing and transitional care.

Aim: To establish a method for the determination of pantoprazole sodium and its related substances. Methods: A column packed with octadecylsiance bonded silica gel (250 mm × 4. 6 mm, 5 pjn) was used. The 0. 01 mol/L monopotassium phosphate solution( adjusted with phosphoric acid to pH 7. 0) -acetonitrile were adopted as the mobile phase, a gradient elution was programmed as follows: 0→30 min(90:10-60:40), 30→45 min(60: 40→15: 85); the detection wavelength was 289 nm; the column temperature was 40 ℃; the flow rate was 1. 0 mL/min. Results: Pantoprazole sodium, the intermediates and its related substances could be well separated. A good linear relationship was obtained over the range of 6. 96-48. 72 μg/mL( r =0. 999 9). The limit detection and quantisation of pantoprazole sodium were 8.51 ng and 17.0 ng, respectively. Conclusion: This method can be applied to control the related substances of pantoprazole sodium and determine pantoprazole sodi-um.

Objective:To study the phenotypes of T cell in patients with Hashimoto thyrioditis (HT) and to analyze its relationship with the impairment of follicles, so as to provide evidence for clinical diagnosis and treatment. Methods: Totally 136 HT specimens were obtained by fine needle aspiration biopsy (FNAB) and were divided morphologically(L, P, O type). The serum parameters (TPOAb, TGAb, TSH) were tested, and 20 cases with nontoxic goiter were taken as control. Immuno-histochemical assay was performed with 60 specimens and FCM (Flow cytometry ) was used to study 23 specimens. The T cell infiltration and the distribution of CD3+ . CD4+ . and CD8+ T cells were compared between all types of HT tissues. The correlationship between the atrophic degree of follicle with T lymphocytes infiltration and phenotype was analyzed. Results: It was found that L type (n = 58) and P type (n = 28) had more serious follicle atrophy than that of O type (n = 20) (P

This paper is to report our study in which the differences between prosthetic restoration and surgical reconstruction using traditional clasp retention technology were analyzed based on three-dimensional finite element methods in our laboratory. Firstly, the maxillary unilateral defect model was developed using medical image processing software MIMICS. Secondly, the prosthesis was generated by mirroring technology. The clasp was designed according to the methods raised by Aramany. Then, the stress distribution of maxilla was calculated by simulating occlusion. According to the results, after osseointegration of surgical reconstruction, stresses of unaffected abutments were reduced significantly, and less stress of junction occurred near zygoma of affected side, which were all less than stresses of prosthesis restoration. Thus, removing the clasp of surgical reconstruction increased the stresses of unaffected abutments. The stress trends of maxillary components were different between prosthetic restoration and surgical reconstruction. Surgical reconstruction is better than prosthesis restoration in protection of the abutments. Clasp can alleviate the occlusal burden of maxilla. Varieties of retentive technologies can be considered in prosthesis restoration. The surgical reconstruction is more conducive to rehabilitate unilateral maxilla biomechanically in clinic.

Aim To evaluate whether the combination of polypeptide AP25 and docetaxel is more efficient in treating experimental breast cancer,than either reagent used alone,and to offer suggestions for clinical use. Methods An experimental breast carcinoma model was set up to investigate the anti-tumor effects of AP25 and docetaxel combination.The Q value was caluculat-ed by Guinness rules and the anti-tumor effects of the combination of polypeptide AP25 and docetaxel were e-valuated.Results The treatment by the combination of polypeptide AP25 and docetaxel showed a better tumor inhibition rate.The combination of AP25 20 mg ·kg -1 and docetaxel 10 mg·kg -1 significantly inhibi-ted the tumor growth with 0.85 1.15,showing a synergistic effect.Conclusions The combination of AP25 and docetaxel can significantly in-hibit the tumor growth with a synergistic effect and de-crease the dose of chemotherapy.

Objective To discuss how to use the core elements of international classification of functioning,disability and health(ICF) as a guide in stroke operation treatment to develop targeted,effective therapy plan and rehabilitation goals,establish individualized treatment of rehabilitation,and to observe the effect of limb movement function in stroke patients. Methods Sixty cases patients with stroke and aged from 40 to 65 years old were selected. The body function and structure of all stroke patients were marked by comprehensive evaluation scores of The National Institutes of Health Stroke Scale ( NIHSS ) and Fugl?Meyer assessment. And then they were randomly divided into two groups,30 cases in each group. The observation group used the Chinese version of brief ICF Core Sets for evaluation, and set individualized treatment according to the results of the assessment;The control group, according to the conventional rehabilitation process, involved in training routine physical therapy. Again 8 weeks after treatment for patients with evaluation,the assessment results was compared with the results of the first assessment. Results Before treatment, the NIHSS, Fugl?Meyer assessment and Chinese version of brief ICF core elements scale scores for the observation group were 7. 95±2. 37,34. 5±4. 0 and 82. 15±17. 96,for the control group were 7. 58±2. 25,34. 8±4. 0 and 81. 55±18. 78. After treatment,the above three rating scale scores, for the observation group were improved to 4. 78 ± 1. 63, 56. 3 ± 4. 2, 60. 45 ±11. 04,for the control group were improved to 5. 13±1. 75,48. 1±3. 8,73. 56±16. 89. The two groups were significantly improved ( observation group:t=4. 94, 15. 51, 18. 59, P<0. 05;control group:t=3. 17, 14. 66, 12. 33,P<0. 05). After treatment,compared with the control group of three rating scale scores(5. 13±1. 75,48. 1
±3. 8 and 73. 56±16. 89),the observation group(4. 78±1. 63,56. 3±4. 2 and 60. 45±11. 04) improved more apparently(t=3. 15,14. 54,15. 45,P<0. 05) . Conclusion Guided by the idea of ICF and scale,with the demand of the patients as the center,to develop personalized physical therapy,can achieve more productive and more targeted rehabilitation goals.
