Objective: To evaluate the effect of Twin-block function al appliance in the treatment of transmissible obstructive sleep apnea syndrome (O SAS). Methods: 7 cases of OSAS, aged 8.6～13.2 years, with sk e letal Angle II malocclusion were treated with Twin-block fuctional appliance fo r 13 months on an average. The position of the mandible, tongue, soft palate,hyo id bone and the radius vector of the upper airway was measured by lateral cepha lometric radiographs, the indexes of sleep condition, breath function and cardio vascular system were measured by polysomnography before and after treatment. Results: At the end of the treatment, the average increase in the radius of upper airway was 4.84 mm (P

Objective:To evaluate the effect of passive smoking on the incidence of children's asthma in our country and abroad.Methods: Based on the 3 Chinese major science literature databases and MEDLINE database,8 articles were selected among all the articles of case control study during 1994 to 2003.The results of 8 Logistic regression on the cause of children's asthma were analyzed by General Variance Based method of meta analysis. Results: The pools regression coefficient b G was 1.101,OR was 3.007, ? 2 was 22.49 ( P

High mobility group A1 belongs to the family of high mobility group. It is widespread in human,and involved in the physiological and pathological situations. It is overexpressed in many human cancers including haematological malignancies as the oncogene.

The research findings published by National Surgical Adjuvant Breast and Bowel Project have continued to change the clinical practice of early-stage breast cancer over the past decade.Sentinel lymph node biopsy has become the new surgical operation standard.The aromatase inhibitor adjuvant endocrine therapy cycle has been extended from 5 years to 10 years, which benefits the patients with high risk and reactivity.Chemotherapy combined with trastuzumab has become the standard adjuvant therapy strategy of human epidermal growth factor receptor-2-positive invasive breast cancer.In addition, the research progress is also related to the optimization of the fields including the postoperative adjuvant chemotherapy and neoadjuvant chemotherapy.

Systemic inflammatory response syndrome (SIRS) and its lethal sequela multiple organ dysfunction syndrome (MODS) are common complications in critical illness, such as severe trauma, shock, infection and major operations. During the past three decades, the evolution in our understanding of SIRS and/or MODS could be divided into three stages. Particularly in recent years, advances in molecular and cellular biology have provided new insights in the pathogenesis of this complex condition. The earlier emphasis on the pro inflammatory mediators involved in propagation of inflammatory response, has gradually been replaced by a realization that SIRS/MODS are the result of an imbalance of pro and anti inflammatory mediators to create the final status of excessive inflammation or immunoparalysis'. Though prognosis remains poor, the knowledge that now exists about SIRS/MODS gives great hope for the future. Progress has been made in new treatment modalities and re evaluation of current available measures. Nevertheless, improved techniques to monitor immunological or other markers of inflammatory and host defense responses will be important in assessing the effects of future therapies on central mechanisms contributing to SIRS/MODS.

Filamentous fungi are widely used for large-scale production of cellulases. Morphological characteristics of mycelia under submerged condition are closely correlated with cellulases productivity. In order to find out the critical genes involved in the mycelial morphology development and cellulases production in liquid fermentation, 95 Neurospora crassa morphological mutants (named as SZY1-95) were screened for cellulases production. Compared with the wild type, cellulases production in four mutants SZY32, SZY35, SZY39 and SZY43 were significantly decreased, whereas mutants SZY63, SZY69, SZY87 and SZY11 produced much more cellulases than that of the wild type strain. Meanwhile, endo-beta-1,4-glucanase activity, beta-glucosidase activity, viscosity of broth and dry weight of these mutants were measured. The mycelial morphology of the mutants was also studied by microscope. Particularly, pellets were formed in mutant SZY11 and SZY43, whose viscosities were 25% and 50% of the wild type strain, respectively. Mutant SZY87 appeared long hyphae, and the viscosity of its broth was at least 2 folds of the wild type strain. These results indicate that a single gene deletion could influence the mycelial morphology in liquid fermentation, and increased the cellulases production. The low-viscosity related genes identified in our study will be the potential candidates for genetic modification of filamentous fungi.

Objective To analyze and discuss the possible reasons of the bone resorption beneath the prostheses after chin augmentation.Methods Twelve patients were admitted to our department for further correction after chin augmentation with materials.The bone resorption was observed through the clinical research and X-ray examination.Results All the patients were underwent the removal of the materials,genioplasty was performed in 8 patients,and two patients were treated by chin augmentation with polyethylene.All the patients were satisfied with their facial contouring.Mild bone resorption was found in seven patients (depth of bone resorption ≤2 mm),in which five patients were used with silicone materials,two patients were performed with expanded polytetrafluoroethylene implants.Moderate bone resorption was seen in three cases.All of them were used with silicone implants (2 mm ＜ depth of bone resorption ≤4 mm).Severe bone resorption happened in two patients (depth of bone resorption ＞4 mm).One was used with silicone implant,and the other one was carried out with expanded polytetrafluoroethylene implant.Conclusions The imbalance among mentalis muscle,materials and underlying bone might be one of the key reasons.Thus for mild and moderate microgenia cases,chin augmentation with material is suitable,while long-term fellow-up study is necessary.But for the cases of severe mirogenia or microgenia and micrognathia with dentofacial deformity or mentalis muscle hyperactivity,genioplasty might be performed as well to correct their deformities.

The paper elucidated the necessity of programmed operation in competence education of medical postgraduate students.This paper introduced the specific methods of programmed operation mode,exactly as selection of the best,scientific combination,coordination and arrangement,allocation of responsibility to individual,exact procedures,succession and development.The seven years practice experience in their colleges testified that these operational methods aroused the enthusiasm of postgraduate students' participation in campus activities and trained postgraduate student cadres.Meanwhile,these methods activated the campus culture and atmosphere and enhanced the comprehensive competence of postgraduates wholly.

Through analyzing the employment situation of pharmaceutical engineering specialty,a variety of employment-oriented practice mode of combining learning with working has been explored,including internships,school-enterprise cooperation,personal contact przctice,combined with the dual selections fair,co-culture with other universities,and attending postgraduate exanl with a research proiect model.As a result,the implementation of these models led to improve students'professional operating skills and eventually encourage graduates to start a career smoothly
