Sinus osteoma is a common nasal and sinus disease, while the clinical cases of osteoma with a diameter greater than 30 millimeter are rarely seen. This paper reports a case of a 39-years-old male patient discovered with one-year long swelling pain in the right eye. The patients' right eye was mildly prominent and he suffered from hypopsia and diplopia. After CT scanned, he have ethmoid osteoma been discovered, besides, the right media rectus compression and orbital apex compression and consequent pathologically were diagnosed. The solid tumor ranged widely from the anterior skull base to the superior and interior orbital walls,and thus deprived the patient's complete surgical resection. As an attempt to prevent complications, most parts of the tumors were sur gically removed.

Objective:To explore the effects of nutritional intervention on the nutritional status,cognitive function and activities of daily living (ADL) in patients with Alzheimer's Disease (AD).Methods:90 AD patients were randomly divided into the control group and the intervention group,with 45 cases in each group.Patients in the control group received anti-dementia drugs,and patients in the intervention group additionally received TPF-T as the oral nutritional supplement.The nutritional status and nutritional biochemical indicators,cognitive function and ADL of two groups were evaluated when enrolled and 6 months later after the treatment.Results:After 6 months'treatment,the nutritional status,MMSE,ADL scores and nutritional indicators of patients in the intervention group were significantly improved compared to the control group (P ＜ 0.05).Conclusion:Nutritional intervention can effectively improve the nutritional status,cognitive function and ADL of patients with dementia.

This paper reports a case of female patient with throat discomfort and coughs for several months. She was discovered by laryngoscopy with a pale yellow lump in the left aryepiglottic fold and pyriformin with the size of 2.0 cm x 1.6 cm. MRI fat suppression sequence exhibited low signal, and the lump was removed by laryngoscope surgery under general anesthesia. Pathological examination showed lipoma. Five years postoperative, her throat discomfort reappeared the laryngoscopy examination showed a pale yellow lump with the size of 2.0 cm x 1.0 cm in the front wall of left side of pyriform. Her MRI fat suppression sequence exhibited low signal again, and the lump was removed by laryngoscope surgery under general anesthesia. Pathological examination showed lipoma and immunohistochemistry proved S100 positive. The patient was discharged a week postoperative and no recurrence was found in the follow up visits in the following year.

This paper reports a case of recurrence of tonsillar cancer on the right 6 months after radiotherapy with pharyngeal hemorrhage for 4 days and aggravation in the next day. The pharyngeal hemorrhage was severe in the case and the maximum of single amount of bleeding was approximately 200 ml. The examination showed active bleeding on the ulcer with a diameter of 2 cm in the right tonsil and the depth of 1 cm. After repeated compression hemostasis proved to be invalid, selective embolization was applied on the patient and the symtoms of pharyngeal hemorrhage disappeared without complications. The patient was discharged after 2 weeks of observation without any recurrence of hemorrhage.

Biodegradable nano/microparticles of poly(D, L-lactide-co-glycolide) (PLGA) is a novel non-viral gene vector, which has many advantages, such as safety, non-immunogenicity, easy of large-scale preparation and well load-capability. Therefore, more and more attentions and researches have been paid on its application. Especially, PLGA has shown enormous potential application value and space in the field of plasmid DNA (pDNA) delivery system. On the basis of the current situation of PLGA nano/microparticles for pDNA delivery, this paper focused on summarizing the current preparation approaches and surface modified methods of PLGA particle, furthermore showing its application in gene therapy and genetic vaccine delivery. These showed that PLGA nano/microparticles have extensive prospect in the development of controlled gene delivery system.

The paper analyses statistically the parameters of acceleration and heart rates in 905 aerobatic maneuvers of 88 sorties. The result indicates that the G levels, rates of increas as well as the duration of acceleration in tactical flight training are higher and longer than routine flight training. There is a significant correlation between the pilot's heart rates and the magnitude of G levels. The pilot's endurance for operating aircraft actively was 1.4G higher in average than that of the centrifuge runs. Af-ter anti-G physiological training, the endurance can be increased 2.24G in average by means of using anti-G suit and L-1 maneuver. The endurance was increased by an average of 1.18G as compare withthat prior to physiological training.

In order to study mechanical stress on root from orthodontic tooth movement by sliding mechanics, a 3-dimensional finite element model incorporating all layers of a human mandibular dental arch with orthodontic appliance has been developed to simulate mechanical stress on root from the orthodontic tooth movement. Simulated orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis was applied to the crown of the teeth. The finite element analysis showed when orthodontic forces were applied to the tooth, the stress was mainly concentrated at the neck of the tooth decreasing uniformly to the apex and crown. The highest stress on the root was 0.621 N/mm(2) for cervical margin of the canine, and 0.114 N/mm(2) for apical region of the canine. The top of canine crown showed the largest amount of displacement (2.417 microm), while the lowest amount of displacement was located at the apical region of canine (0.043 microm). In conclusion, this model might enable one to simulate orthodontic tooth movements clinically. Sliding force at 2 N is ideal to ensure the bodily orthodontic tooth movement. The highest stress concentration in the roots was always localized at the cervical margin when orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis, so there may be the same risk of root resorption when orthodontic force of 2 N at 0, 30 and 45 degree was used in clinic cases.
