OBJECTIVETo observe the effect of transcutaneous acupoint electrical stimulation (TAES) on brain tissue oxygen and glucose metabolism of the brain tissue in peri-operative period of the craniocerebral operation.

METHODSFifty patients scheduled for neuro-surgery were randomly assigned to the treatment group and the control group equally. Anesthesia applied after induction on all patients was continuous sevoflurane inhalation and intermittent intravenous injection of sulfenany and vecurnium bromide, but to the treatment group TASE was applied additionally from 30 min before anesthesia to the end of operation. Blood samples were taken from artery and jugular venous bulb at different time points, i. e. before induction (T0) , before skin incision (T1) , at the end of operation (T2) , and 10 min after extubation (T3) , for blood-gas analysis. The difference of oxygen, glucose and lactate contents between blood samples of arterial and jugular bulb (Da-jvO2, Da-jvGlu and Da-jvLac) at respective time point were determined and calculated.

RESULTSDa-jvO2 decreased in both group at T1, T2 and T3, and all lower than that at T0 (P < 0.05 or P < 0.01), but significant difference was shown in comparison of the index at T2 and T3 with the same time points in the control group in the treatment group (P < 0.05 or P < 0.01) , and that between groups at T2 and T3 (P < 0.01). Da-jvGlu in the treatment group decreased at T2 and T3 (P < 0.05), but keep unchanged relatively in the control group before and after anesthesia, inter-group comparison showed it was lower at T2 and T3 in the treatment group than that in the control group respectively (P < 0.05). Da-jvGlu in the treatment group at T1, T2, and T3 were all lower than that at the same time points (P < 0. 01).

CONCLUSIONTAES can significantly decrease the oxygen and glucose metabolism of the brain tissue in the perioperative period of the craniocerebral operation.

OBJECTIVETo explore the effect of Ang-2 on angiogenesis in gastric cancer.

METHODSThe expression of Ang-2 mRNA was analyzed by RT-PCR and the expression of VEGF and CD34 was detected by immunohistochemistry in 36 cases of gastric cancer tissues and their paired adjacent gastric mucosa.

RESULTSThe expression of Ang-2 mRNA was found both in gastric cancer and their paired adjacent gastric mucosa; the correlationship between the general expression levels of Ang-2 mRNA and microvessel density (MVD) in gastric cancer tissues was not found. However, in 27 cases whose Ang-2 mRNA expression levels in cancer tissues were lower than those in adjacent gastric mucosa. A significant positive correlation between the expression level of Ang-2 mRNA and MVD in the tumor tissues was found (r = 0.411, P < 0.05). In these 27 cases, the MVD in the gastric cancer tissues with positive VEGF expression (45.45 +/- 10.30) was higher than that with negative VEGF expression (30.15 +/- 8.69, P < 0.05), whereas in the other 9 cases whose expression levels of Ang-2 mRNA in cancer tissues were higher than those in adjacent gastric mucosa, a significant negative correlation between expression level of Ang-2 mRNA and MVD in the tumor tissues (r = -0.758, P < 0.05), but without correlation between the MVD and VEGF.

CONCLUSIONUnder the conditions that the expression of Ang-2 mRNA in cancer tissues was lower than that in adjacent gastric mucosa, VEGF could promote the sprouting of new vessels along with Ang-2 upregulation. But under the conditions that the expression of Ang-2 mRNA in cancer tissues was higher than that in adjacent gastric mucosa, Ang-2 inhibited angiogenesis. Angiopoietin-2 may play a dual effect on angiogenesis in gastric cancer.

OBJECTIVETo study the pathogenesis, the diagnostic criterion and the surgical methods of congenital nasal ethmoidal sinus malformation with false triple nostrils appearance.

METHODSFrom Feb 1993 to Mar 2006, a total of 13 cases of rare congenital nasal deformity had been investigated in pathogenesis, clinical manifestations, differential diagnosis and the methods of operation. The concept of congenital nasal sinus was presented. In this series, one-stage rehabilitation was achieved by using compositive operation techniques, including excision of the sinus, reconstruction of the hatch of ethmoidal sinus, transplantation of the dorsal nasal musculoaponeurotic flap as well as the nasolabial fold flap and the reconstruction of the cartilage-muscle ring in the wing of the nose.

RESULTSThe symptom disappeared in all of the 13 cases with no morbidity. The symmetrical double sides were observed and the nasal figure was satisfied.

CONCLUSIONSBy using such compositive operation techniques, including excision of the sinus, reconstruction of the hatch of ethmoidal sinus in middle nasolabial, transplantation of the dorsal nasal musculoaponeurotic flap as well as the nasolabial fold flap and the reconstruction of the cartilage-muscle ring in the wing of the nose, one-stage rehabilitation could be reached. It was an ideal, safe and reliable method to cure this kind of rare congenital nasal deformity.
