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.

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.

OBJECTIVETo explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.
METHODSThe 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.
RESULTSAt the 15 min and 30 min point after anesthesia, SaO2 in GA group was significantly increased compared to that in the EA group (P < 0.05). At 15 min, 30 min and 60 min point after anesthesia, MAP in CSEA group was significantly increased compared to that in the EA group (P < 0.05). At 30 min point after anesthesia, HR in CSEA group was increased significantly compared to the EA group (P < 0.05). At 15 min and 30 min point after anesthesia, SaO2 in the CSEA group was increased significantly compare to the EA group (P < 0.05). Compared with preanesthesia (T0) in EA group, MAP, HR and SaO2 decreased significantly at 15, 30 and 60 min after anesthesia (P < 0.05). The fluctuation of the three parameters in GA and CSEA groups were relatively small (P > 0.05). As well as the comparison of abnormal ECG among the 3 groups was concerned, the incidence of ST-T changes in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia and at the time of surgery termination (P < 0.05, P < 0.01). The incidence of arrhythmia in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia (P < 0.05, P < 0.01). Compared with T0 in the same group, the incidences of ST-T changes and arrhythmia in GA or CSEA group at the time of 15, 30 and 60 min after anesthesia and at the time of surgery termination were significantly lower than that before anesthesia (P < 0.05, P < 0.01).
CONCLUSIONGA and CSEA have less impact on hemodynamics and have smaller incidence of abnormal ECG of old CHD patients with abdominal operation.

Rice straw degradation with white rot fungi and cellulose multienzyme was studied. The results indicated that the LiP, MnP activity produced by P. chrysosoporium 172 could reach 28.3U/g and 12.6U/g respectively under suitable culture condition. And the lignin was degraded efficiently in contrast with the cellulose and hemicellulose in rice straw solid fermentation. Following treatment with white rot fungi, using multienzyme produced by A. niger NL-1 could greatly accelerate the decomposition of rice straw. The decomposition rate of cellulose, hemicellulose, lignin and the loss rate of dry material were 53.8%,57.8%,44.5% and 46.3% respectivity when hydrolysis rice straw 48h with cellulase multienzyme (including 3 IU /g rice straw) after culture P. chrysosoporium 172 for 10 days. Scanning electron microscope analysis showed the cell wall of rice straw was destroyed severely, and the whole tissue got loosely. These results demonstrated the rice straw had been decomposed efficiently and completely.
