OBJECTIVETo explore the role of histone H3 acetylation in cleft palate induced by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin (TCDD) in C57BL/6J mice, and its mechanism.

METHODSOn gestation day 10 (GD10), 36 pregnant mice were randomly divided into two groups as the treated group(n = 18) and the control group( n = 18). The mice in the treated group received intragastric administration with TCDD 28 μg/kg, while the mice in the control group received equivalent corn oil. The pregnant mice were sacrificed on GD13. 5, GD14. 5 and GD15. 5, collecting fetal palates to determine the activities of histone acetyltransferases (HATs) by Colorimetric and the expression level of acetylated histone H3 (Acetylated histone H3, Ac-H3) by Western-blot.

RESULTSThe activity of HATs was 0.409 7 ± 0.0147, 0.522 3 ± 0.017 1 and 0.643 5 ± 0.013 9 in control group on GD13.5, GD14.5 and GD15.5; 0.865 0 ± 0.0129, 0.719 1 ± 0.017 8 and 0.551 2 ± 0.016 8 in TCDD group. The activity of HATs in TCDD group was higher than that in control group on GD13. 5, GD14. 5, showing significantly difference between the two groups (t = - 56. 932, t = - 19. 516, P < 0.01); however, the activity of HATs in TCDD group was significantly lower than that in control group on GD15. 5 (t = 10. 382, P < 0.01). The expression level of Ac-H3 was 0.745 0 ± 0.113 5, 1.055 9 ± 0.249 4 and 1.795 5 ± 0.081 9 in control group on GD13. 5, GD14. 5 and GD15. 5; while 1.4490 ± 0. 1460, 1. 641 8 ± 0.099 7 and 1. 512 1 ± 0. 150 2 in TCDD group. The expression of Ac-H3 in TCDD group was higher than that in control group on GD13. 5, GD14. 5, showing significantly difference( t = -6. 593, -3. 779, P <0. 01, P <0.05) ; However, the expression of Ac-H3 in TCDD group was statistically lower than that in control group (t = 2. 870, P <0. 05).

CONCLUSIONThe acetylation of histone H3 was involved in the cleft palate of C57BL/6J mice induced by TCDD, which may be one of the mechanisms in TCDD-induced cleft palate.

OBJECTIVETo explore the clinical effect of using dorsal two wing-shaped flap to reconstruct finger web for treatment of congenital syndactyly.

METHODSThis technique has been used in 19 children with congenital syndactyly. At the dorsum, a flap with V-shaped tip and two wing-shaped pedicle were designed and was just sewed up with an anchor-shaped incision at the palm. The web was primarily reconstructed without skin graft at base of fingers. Distal end of fingers were separated by using serrated flap and were closed after removal of fatty tissue. At some cases with tight skin connection. The defect area at lateral and distal end of fingers was closed by small pieces of skin graft.

RESULTSAll the webs were reconstructed primarily without skin graft at the base of fingers. 7 cases with tight skin connection had small pieces of skin graft at lateral and distal end of fingers. Primary healing was achieved in all cases. After 1 to 6 months of follow-up, both the appearance and function were satisfactory without conspicuous scar. The reconstructed finger webs were in normal depth and width.

CONCLUSIONSPrimary web space can be achieved by dorsal two wing-shaped flap without skin graft at base of fingers. It is one of the best choices for treatment of congenital syndactyly.

Objective To investigate the role of GABAB1 receptors in spinal dorsal horn neurons in the development of diabetic neuropathic pain (DNP). Methods Sixty pathogen free male SD rats aged 4 weeks weighing 150-170 g were randomly divided into 2 groups ( n = 30 each): control group and DNP group. Diabetes mellitus was induced by single intraperitoneal injection of streptozotocin 50 mg/kg. Blood glucose levels and paw withdrawal threshold to mechanical stimuli were measured at 3, 5 and 7 weeks (T1, T2, T3 ) after IP STZ/NS ( n = 10 each). The animals were sacrificed after PWL measurement. The lumbar segment of the spinal cord was removed for determination of the expression of GABAB1 receptors by immuno-histochemistry, RT-PCR and Western blot analysis. Results The blood glucose levels were significantly higher while the PWT was significantly lower at T1,T2 and T3 in group DNP than in control group. The expression of GABAB1 receptor mRNA and protein in spinal dorsal horn was significantly lower at T2 and T3 in DNP group than in control group. Conclusion The expression of GABAb1 receptors is down-regulated in spinal dorsal horn neurons in rats with DNP.

Objective To evaluate the role of M3 muscarinic acetylcholine receptor (M3 mAChR) in the release of glycinergic neurotransmitter by using oxotremorine-M (Oxo-M: a nonselective mAChR agonist) and 4-diphenylacetoxy-N-methylpiperidine methiodide (4-DAMP: a highly selective M3mAChR antagonist). Methods Twenty male 3-4 weeks old SD rats weighing 160-180 g after successful intrathecal catheterization were randomized into 2 groups (n = 10 each): normal saline group (group NS) and pertussis toxin (group PTX).Pertussis toxin 1.5 μg/10 μl was injected IT in group PTX, while in group NS normal saline 10 μl was injected IT instead. The animals were killed at day 7 after injection. The spinal cords were removed and sliced and placed in artificial CSF. Glycinergic spontaneous inhibitory postsynaptic currents (sIPSCs) were measured in spinal lamina Ⅱneurons using whole-cell voltage-clamp technique. Five minutes after sealing, Oxo-M (final concentration 3 μ mol/L) was added. Oxo-M was then completely washed out 3 min later and 4-DAMP (final concentration 25 nmol/L) was added after 5 min of stabilization. In the presence of 4-DAMP, Oxo-M (final concentration 3 μmol/L) was added again 3 min later. sIPSCs were recorded before addition of Oxo-M (T1), 3 min after addition of Oxo-M (T2), 3 min after addition of 4-DAMP (T3), 3 min after the second addition of Oxo-M (T4). Results Compared with the baseline value at T1 , Oxo-M significantly increased the frequency of glycinergic sIPSCs at T2without changing the amplitude at T2-4 in both groups. The frequency of sIPSCs was significantly lower at T4 than at T2 in both groups (P ＜ 0.05 or 0.01). There was no significant difference in both frequency and amplitude of glycinergic sIPSCs between the two groups. Conclusion M3 mAChR plays a predominant role in the release of glycinergic transmitter in the spinal lamina Ⅱ neurons in rats.
