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.

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 determine the effect of peripheral nerve regeneration through NGF ·HAMM (Nerve growth factor and Human Ammion membrane Matrix) grafts. MethodsA 1.2 cm defect of the left sciatic nerve were made and then repaired randomly by means of autogenous nerve bridging (group N),NGF · HAMM microporous conduit bridging (group NH) or HAMM microporous conduit bridging (group H) in 60 adult Wistar rats. There were 20 animals in every group. At 1,2 and 3months post operation,the following items as qualitative histology,quatitative histomorphometry,electrophysiology and functional assessments of end-organ reconnection were determined. ResultsAt 2and 3 months post operation,Motor nerve conduction velocity (MNCV) of the nerve repaired with HAMM were lower than that of the nerve repaired with autograft and NGF · HAMM. At 3 months post operation,there was no significant difference between NH group and N group in nerve conduction velocity (P>0. 05). At 2 and 3 months post operation,both NGF · HAMM conduit and nerve autograft groups showed more nerve fibers,bigger axon diameter and thicker meylin sheaths than H group.Conclution The combination of HAMM and NGF world enhance nerve regeneration and myeliogeny,as well as could cooperatively promote the functional recovery of injured nerves and limbs. Our results indicate that the NGF · HAMM microporous conduit is a promising tool for use as a nerve guide tube in peripheral nerve regeneration.

ObjectiveTo study the relationship between Borna disease virus (BDV) and the human viral encephalitis.MethodsThe P24 fragment of BDV RNA in peripheral blood mononuclear cells (PBMC) from 59 patients with viral encephalitis diagnosed clinically, and 112 healthy donors were examined by fluorescence quantitative nested reverse transcriptase polymerase chain reaction (FQ-nRT-PCR).ResultsThere were 3 positive of BDV P24 fragment in 59 patients with viral encephalitis, and no positive in blood donors. The positive rate of BDV p24 in PBMC in viral encephalitis (5.08%) was higher significantly than that in blood donors (P

Objective To elucidate the effect of ex vivo expansion of umbilical cord blood (UCB) mononuclear cells (MNCs) on their implantation capability and the hematopoietic reconstitution, and to find a feasible way of applying ex vivo expanded UCB MNCs to clinical transplantation.Methods UCB MNCs were cultured in short-term in serum-free medium with different early acting cytokines combinations in order to observe the amplification result and cells apoptotic difference. The 6-day expanded cells were transplanted into sublethally irradiated NOD/SCID mice to assess the implantation and the hematopoietic reconstitution of the survival mice.Results UCB MNCs reached the best amplification result between day 6 and day 10 with the contribution of SCF, FL, IL-6 and IL-3 in common and the presence of Annxin V on the surface of cells obviously decreased. Six weeks after transplantation, CD45, CD34, CD33, CD3 and CD19 antigen could be detected by FCM on BM, spleen and thymus cells of the alive mice and the human specific Alu and Cart-Ⅰ repetitive sequence could be detected in the DNA obtained from peripheral blood by PCR.Conclusion After 6-day effective expanding with SCF+FL+IL-6+IL-3 UCB MNCs can be implanted into NOD/SCID mice successfully and contribute to reconstitute the multiple hematopoiesis.
