Objective To describe our experience and method of reconstruction after resection of tumors around inner canthus and nasion in the elderly. Methods The line between outer and inner canthus was considered during reconstruction.If the surface of wound after resection was above this line,glabellar flap was used to reconstruct the upper part and the residual defect was repaired with advancement of lower eyelid and rotation of flap.If the surface of wound was below this line,lower eyelid flap was used and the residual defect was reconstructed with glabellar flap. Results All flaps survived without any significant complications.9 cases among 15 patients were followed up from 1 to 24 months.Repaired tissues all matched well with surrounding tissue in color,texture,and outline.Eyelid and medial canthal were not disturbed and there was no tumor recurrence.Scars were smoothy,soft and hidden with satisfactory appearance and vision. Conclusions Single local flap or combined local skin flaps around the nasion and inner canthus is one of reconstruction methods to get satisfactory cosmetic effect or facial morphology.

This study is to investigate the anti-allergic effect of anthocyanidin and to explore its possible mechanism. The experiments of passive cutaneous anaphylaxis reaction (PCA) and colorimetry were used to determine the effect of anthocyanidin on degranulation of mast cells in vivo. For in vitro study, various concentrations of anthocyanidin (100, 50 and 25 micromol x L(-1)) were added to the culture medium of mast cells cultured with 100 microg x L(-1) of dinitrophenyl (DNP) specific IgE overnight. The azelastine (100 micromol x L(-1)) was selected as the positive control. The antigen (DNP-human serum albumin, DNP-HAS)-induced release of degranulation was measured by enzymatic assay, histamine was determined by EIA, and interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were measured by Western blotting, separately. In addition, the effects of anthocyanidin on phosphorylation of NF-kappaB, p38MAPK and Akt were observed by Western blotting. The results showed that treatments with anthocyanidin (100 and 50 mg x kg(-1)) were followed by a decrease in PCA of rats. Anthocyanidin (100 and 50 micromol x L(-1)) obviously suppressed the degranulation from mast cells, whereas results from anthocyanidin (100 and 50 micromol x L(-1)) group indicated significant inhibitory effect on histamine, the calcium uptake, TNF-alpha, IL-6, phosphorylation of NF-kappaB, p38MAPK and Akt of mast cells induced by antigen. Anthocyanidin may suppress the anaphylactic reaction by inhibiting the action of mast cells. NF-kappaB, p38MAPK and Akt at least in part contribute to this event.

To obtain the genome sequence of human bocavirus 2 (HBoV2), different regions of HBoV2 genome were amplified through PCR in fecal specimens which had been identified as single-positive for HBoV2 in 2010. A genome sequence of HBoV2 (HBoV2-NC, 5444 bp) was obtained after sequence assembly. The phylogenetic analysis showed that HBoV2-NC had the closest evolutionary relationship with HBoV2 Lanzhou strain. The predication of inverted terminal repeats of HBoV2-NC by DINAMelt showed that inverted terminal repeats were contained in HBoV2-NC 5' terminal, which had the typical stem-loop structure in other parvoviruses. Finally, some flanking sequences of HBoV2-NC were amplified by linker-PCR.

Human bocavirus 1 (HBoV1) is a novel virus that mainly causes respiratory tract infection, and it has the characteristic of genome of Parvovirus, containing three open reading frames that encode non-structural proteins NS1 and NP1 and structural proteins VP1 and VP2. Circular episome is present during the rolling circle replication of HBoV1, which provides the possibility of full genome amplification and infectious clone construction to save HBoV1. The recombination between HBoV1 and HBoV2-4 occurs frequently. With the three-dimensional culture, in vitro culture of HBoV1 provides a powerful tool for research on the pathogenesis of HBoV1. This review focuses on the molecular characteristics, association with diseases, in vitro culture, diagnosis and treatment of HBoV1.

Ultrasonic microbubbles were used to open blood-brain barriers (BBB) with a reversed and limited behavior feature in the study, which could improve the brain-targeted delivery of anti-tumor drugs. The glioma rat model was prepared. Low-frequency ultrasound was combined with microbubbles to affect the permeability of BBB compared with the permeability of independently administered Evans blue (EB) crossing BBB. Time point and length of ultrasound were investigated whether they affect the permeability of BBB and the damage of brain tissue. The effect of the growth time of glioma on BBB permeability was explored. Only glioma had a very little impact on BBB permeability. However, ultrasonic microbubbles opened the BBB with the features of temporary, limited and reversed behavior and improved EB and magnetic resonance imaging contrast agent penetrating BBB. A length of 30 s ultrasound is appropriate for opening BBB and no damage of brain tissue. Drugs should be injected before ultrasound so that they enter into brain as BBB opening. Ultrasonic microbubbles can open BBB effectively and safely, which improve drugs penetrating BBB under proper time point and length.

A patient with severe hypoglycemia due to insulin-like growth factor ( IGF)-IIsecreted by a giant solitary fibrous tumor of the pleura ( SFTP) was investigated through comprehensively reviewing his medical history and clinical records. The patient had severe hypoglycemia accompanied with significantly decreased serum insulin level. A solitary fibrous tumor of the pleura was found, and right pneumonectomy removed this giant tumor. Two years after the operation, the patient was fit and well with no further hypoglycemia episodes. Non-islet-cell tumor hypoglycemia should be considered in patients who have hypoglycemia episodes accompanied with significantly decreased serum insulin level.
