The most common forms of treatment for amblyopia are occlusion therapy and pharmacologic penalization. But these methods can not recover all the visual deficits of amblyopes and there are some disadvantages of the treatment which need to be considered, including adverse effects, compliance and social stigma. Recently, some novel approaches are investigated for improving the effectiveness and compliance of treatment for amblyopia.

Objective The presence of alloreactive memory T cells in recipient is a critical handicap to achieve transplantation tolerance.To make a mouse model which mimics the present transplant patient is important for research at this subject.Thus,we developed a novel re-transplant model and compared the alloresponse in this model with that in the conventional memory T cellstransfer model (transfer control).Methods The re-transplant model was established via microsurgery and vessel cannula techniques,and the experiment was composed of three groups:the re- transplant group,memory T cell-transfer group (transfer control) and the conventional blank group (blank control).The research indexes included survival time of donor heart,rejection score of allograft,and detection of proliferation and differentiation of the alloreactive memory/effector T cells by by flow cytometry (FCM) and in vitro mixed lymphocyte reaction (MLR).Results The median survival time of allograft in re-transplant recipients was significantly shortened compared to that of transfer control,but there was no significant difference in rejection score of graft between them (the score in retransplant group was the most intense of the three groups). Moreover, proliferation and differentiation of the alloreactive effector T cells were more intensive in re- transplant recipients than in the transfer control,which was confirmed by in vitro MLR and by FCM of the splenocytes for detecting CD44highCD62L-memory/effector phenotype cells.Conclusion The recall alloresponse in retransplantation is more intensive than that in memory-transfer setting and this re-transplant model is more close to the clinic situation than the memory-transfer model in rodents.

Objective:To establish the quality control of Zhiqikang capsules. Methods:TLC was used to identify Gastrodia tuder halimasch, rhubarb and Astragalus mongholicus in the preparations. A spectrophotometry method with 3, 5-dinitrosalicylic acid (DNS) was used to measure the polysaccharide content in Zhiqikang capsules. A spectrophotometry method with Forint phenol method ( Low-ry) was used to measure the peptide content in the capsules. Results:The linear range of polysaccharide was obtained between 6. 412 and 32. 060μg·ml-1(r=0. 999 5), the average recovery was 95. 86% and RSD was 0. 86%. The linear range of peptide was ob-tained between 0.059 7 and 0.298 4 mg·ml-1(r=0.999 0), the average recovery was 100.3% and RSD was 1.88%(n=6). Conclusion:The assay method is simple and accurate in the quality control of the preparations.

Objective To establish an HPLC method for the determination of anthraquinones including rhein, emodin and chrysophanol in xinshenyan capsules. Methods Anthraquinones were determined by HPLC with Phenomenex-C18 column (250 mm×4. 6 mm, 5 μm) as the chromatographic column and methanol-1% acetic acid (70:30) as the mobile phase. The flow rate was 1. 0 mL·min-1 and the detection wavelength was set at 254 nm. Results The liner range of rhein, emodin and chrysophanol was 4. 96-24. 80 μg·mL-1(r=0. 999 6), 6. 58-32. 91 μg·mL-1(r=0. 999 9) ,and 15. 11-75. 55 μg·mL-1 (r=0. 999 9),respectively, and the average recovery was 100. 78%, 98. 13% and 99. 29%, respectively. Conclusion The method is simple and practical, the result is accurate and reliable and it can be used to determine the contents of rhein, emodin and chrysophanol in xinshenyan capsules.

Through several years of exploration in Shanghai Chongming region, the team from Chongming Branch of Xinhua Hospital has established the initial multidisciplinary diagnosis and treatment model of cancer pain, which includes the department of oncology, anesthesiology, pain, rehabilitation, psychology and so forth. By means of medical informationization, they take cancer pain management as the starting point and have initially real-ized a new model of the real-time assessment and treatment of cancer pain, which has helped patients effectively reduce the physical and psychological suffering, improved the quality of life, developed a healthy self-manage-ment of patients, and has reference significance to palliative care.

OBJECTIVE: To analyze the relation between the clinical outcome and the integrity of the facets after a lumbar operation,and to provide a reference for choosing operative method and clinical prognosis. METHODS: Forty-three patients with complete data underwent uni-segment discectomy were enrolled. There were 3 surgical interventions: open-window discectomy, full or semi-laminectomy. Groups were divided based on the integrity of the facets after the operation, and the clinical symptoms and signs were evaluated using the Japanese Orthopaedic Association Back (JOA) scores at 24-month follow-up. RESULTS: Preoperative JOA scores were not significantly different among the groups (P>0.05). Compared with the facet intact group at 24-month follow-up,JOA scores were descended statistically in total uni-facetectomy group and total uni-facetectomy plus partial opposite facetectomy group (P<0.01). CONCLUSION Keeping facets integrated plays an important role in achieving good clinical results,and the damage of facet should be avoided in the lumbar operation.

OBJECTIVE: To design and manufacture a new type instrument and its matching tools for the proximal femur. METHODS: A new type instrument of subtrochanterical fracture-static 3-dimensional screw-plate system(STDSP)was designed and manufactured. The different types of accessory instruments which adapted to STDSP,the aiming guide, and the accessory tools were also designed and manufactured, and they were tested on bones. RESULTS: STDSP included 3 special lag screws and 1 anatomic plate. The lag screws distributed in femoral neck like "or"shape. There was 135 degree between the lag screws and femoral shaft. The shape of the plate was similar to the anatomic structure of the proximal thighbone. The posterior screw was stably connected to the plate. The plate was affixed crosswise to the lateral and anterior side by bicortical screws. The aiming guides and all kinds of accessory tools could help to install STDSP exactly and conveniently,which was verified on cadavers and X-ray photographs. CONCLUSION STDSP has the function of dynamic compressing in 3-dimensional space, and can match with the structure of the proximal femur preferably. STDSP may be a suitable instrument to the subtrochanteric fractures. The accessory apparatus of STDSP has simple configuration,and can let the STDSP be installed accurately, conveniently and rapidly.

OBJECTIVE: To investigate the curative effect of the treatment of reserving limb for patients with malignant bone tumor. METHODS: Forty patients with bone neoplasms underwent the operation of reserving limbs. The neoadjuvant chemotherapy was given to all the patients before the operation. After the ablation of the tumor we used the artificial prosthetic replacement,tumor tissue deactivation and reimplant, variant bone and joint transplantation to reserve the limb. RESULTS: All the patients were followed up. The average follow-up time was 34.8 months. Eight patients got complications. And the fineness rate was 72.5% according to functional evaluation standard of Enneking after surgical treatment of bone tumor. CONCLUSION The operation of reserving limb was an ideal method to cure the malignant bone tumor. The proper operative treatment with neoadjuvant chemo-therapy is helpful to extend the life of the patients and increase the quality of life.

OBJECTIVE: To evaluate the curative effects of AO clavicular hook plate in the treatment of dislocation of acromioclavicular joint and fracture of distal clavicle. METHODS: We retrospectively analyzed the clinical data of 39 patients with acromioclavicular joint dislocation or distal clavicle fractures treated with clavicular hook plate: 16 suffered from dislocation of acromioclaviculr joint, 18 suffered from far end collarbone fractures, and 5 patients had both symptoms. RESULTS: The 39 patients were followed up for 12 months averagely. All patients got good reduction and fixation. The acromioclavicular joint subluxation, breakage, and loosening of the clavicular hook plate were not observed. The acromioclavicular joint recovered quickly. CONCLUSION AO clavicular hook plate is a good choice for acromioclavicular joint dislocation and distal clavicular fracture.
