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.

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.

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.

Objective Vessel injury provokes the release of angiotensin II that influences the proliferation and migration of vascular smooth muscle cells (VSMCs). T lymphocytes produced, interleukin 10 is of immunoregulatory function. The purpose of this study is to determine the effects of recombinant human interleukin 10 (rhIL 10) on the proliferation of isolated rat vascular smooth muscle cell and the activity of p44/p42 mitogen activated protein kinase (MAPK) promoted by angiotensin II. Methods Rat aortic VSMCs were cultured and treated with rhIL 10 or angiotensin II, and then co treated with rhIL 10 and angiotensin II. The proliferation was quantified by colormetric assay. The p44/p42 MAPK activity was evaluated by the immunobloting technique using anti p44/p42 phospho MAPK antibody. Results Compared with control group, angiotensin II stimulated significantly VSMCs proliferation(1 311?0 201 vs 0 781?0 236, P 0 05), but significantly inhibited VSMCs proliferation induced by angiotensin II at a dose of 1,10,100 ng/ml (0 984?0 172 , 0 932?0 134 , 0 784?0 097 vs 1 311?0 201, P

Light cannot be propagated within the range of photonic crystal band gaps. Based on this unique property, we proposed a method to improve anti-radiation capability through one-dimensional photonic crystal coating. Using transmission matrix method, we determined the appropriate dielectric materials, thickness and periodic numbers of photonic crystals through Matlab programming simulation. Then, compound one-dimensional photonic crystal coating was designed which was of high anti-radiation rate within the range of X-ray. As is shown through simulation experiments, the reflection rate against X-ray was higher than 90 percent, and the desired anti-radiation effect was achieved. Thus, this method is able to help solve the technical problems facing the inorganic lead glass such as thickness, weightiness, costliness, high lead equivalent, low transparency and high cost. This method has won China's national invention patent approval, and the patent number is 201220228549.2.

OBJECTIVE: To explore the application of the Dexmedetomidine utend drug induced sleep endoscopy. METHOD: Forty-four OSAHS patients diagnosed by PSG randomly were divided into group A (Dexmedetomidine group) and group B (Propofol group), each group of 22 cases. Group A: pump the Dexmedetomidine (1 microg/kg) over 15 minutes. Once the patient reached a satisfactory level of sedation, the electronic nasopharyngoscope was introduced into the nasal cavity group B: the propofol (2 mg/kg) was intravenous injected, use the same exmination after the object patients falling asleep. If not, double the injection dose of the two group. Observe and record the patient vital signs, EEG and sleep time, and handle the complications. RESULT: The study was successfully completed both in group A and B. Mean arterial pressure (MAP) in group B was lower than group A during the examination significantly (P < 0.05). The time falling to sleep in two groups were (13.4 +/- 2.5) min and (6.6 +/- 1.2) min, and the time in group A was much longer than that in group B. The lowest oxygen saturation during the examination in two groups were 0.835 +/- 0.096 and 0.691 +/- 0.095, and the difference was statistically significant. There was no incidence of adverse reactions in two groups. CONCLUSION Compared with propofol, Dexmedetomidine is a safer sleep-inducing drug, and it can be used for clinical sleep endoscopy.

It is necessary to refresh our understanding of the academic mission for information retrieval course in the network information era.The correlation between scientific achievements and scientific information and between scientific literacy and information literacy revealed the fact that information retrieval capability is the core of information literacy when the information retrieval course is placed a broader academic background.The connotation of information retrieval was elaborated, which further demonstrates that the academic mission for information retrieval course is to train the information wisdom of undergraduates.

Objective To investigate effects of ginkgo biloba extract(GBE) and tanshinoneⅡ A preventative administration against cerebral ischemia and reperfusion injury in gerbils.Methods Cerebral iscthemia and reperfu- sion injury were made by 10 minutes'occlusion of bilateral carotid arteries followed by 24 hours' reperfusion in ger- bils.GBE,tanshinone Ⅱ A,nimodipine or GBE plus tanshinone Ⅱ A were administrated intragastrically 3 days prior to and at the day of ischemia and reperfusion.Effects of experimental agents on mortality,stroke index,brain body index,water content in brain hemisphere,level of SOD activity and MDA in cerebral tissue were measured,and pathological changes of cortex and hippoearnpal CA1 sector were observed.Results GBE 48 mg/kg and tanshinone Ⅱ A 25mg/kg preventive administration could significantly reduce the stroke index,brain body index,and water in brain hemisphere,together with a reduced mortality of cerebral ischemia and reperfusion injuried gerbils.The two a- gents could also significantly improve the activity of SOD,reduce the level of MDA in cerebral tissue and the injury in cortex and hippocampal CA1 sector.Moreover,combined treatment of these two agents demonstrated more signifi- cant effects.Conclusion GBE,tanshinone Ⅱ A and combined therapy of these two agents may protect cerebral func- tion from ischemia and reperfusion injury through reducing the cerebral edema and attenuating the injury of oxygen free radicals.
