OBJECTIVETo assess the association between polymorphism of methylenetetrahydrofolate reductase (MTHFR) gene C677T locus and nonsyndromic cleft lip with or without cleft palate (NSCL/P) in Shanxi Province of China.
METHODSBlood samples from 150 patients and their parents and 150 controls and their mothers were collected. The polymorphism of MTHFR gene C677T locus were analyzed by the methods of polymerase chain reaction and restriction fragment length polymorphism technique(PCR-RFLP). Case-control analysis, transmission-disequilibrium test(TDT) and haplotype-based haplotype relative risk analysis(HHRR) were used to study the correlation between the gene mutation and NSCL/P.
RESULTSHardy-Weinberg equilibrium test results showed that, the offspring and mother genotype in the case group and the control group was not deviated from the Hardy-Weinberg law of genetic equilibrium (P > 0.05). The distribution of genotype CC, CT and TT in offspring had significant difference between the two groups (P < 0.05). In the offspring and mother of case group and the control group, the carriers of the TT genotype compared to CC genotype, the OR are greater than 1 and 95% CI do not contain 1 (offspring OR: 2.692, 95% CI: 1.319-5.495; mother OR: 2.469, 95% CI: 1.136-5.363). The distribution of C allele and T mutation gene were significantly different in the offspring and mother between the two groups (P < 0.05). The TDT test showed: chi2 = 4.507, P < 0.05. The HHRR test showed: P < 0.05.
CONCLUSIONThe single nucleotide polymorphism of MTHFR C677T locus is associated with the development of NSCL/P in Shanxi Province.

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.

Objective To investigate the effect of propofol on the learning and memory function in neonatal rats under hypoxic conditions. Methods Eighty-four 7-day-old SD rats were randomly divided into 6 groups (n = 14 each): propofol + 18% oxygen (propofol-hypoxia, group PH), propofol + air (group PA), propofol +100% oxygen (propofol-oxygen, group PO), 0.9% normal saline (NS) + 18% oxygen (group CH), NS + air (group CA), NS + 100% oxygen (group CO). The rats received injection of intraperitoneal propofol 50 mg/kg or NS 5.0 ml/kg once a day for 7 consecutive days and they were exposed to 18% oxygen, air or 100% oxygen at the end of each injection. SaO2 and respiratory rate (RR) were monitored and recorded after administration. The rats were returned to the cage after recovery of the righting reflex. Six rats in each group were sacrificed 24 h after the 7th injection, and the brain tissues were taken to observe the apoptosis in hippocampal neurons. Morris water maze test was used to test the learning and memory function 2 weeks after administration in the other rats. Results RR was significantly lower and the escape latency at T1.2 longer in group PO than in group CO (P < 0.05). RR and SaO2 were significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crossing the original platform was reduced in group PA compared with group CA, and in group PH compared with group CH (P < 0.05). Compared with group PO, SaO2 was significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crosing the original platform was reduced in group PA (P < 0.05). Conclusion Propofol induces apoptosis in hippocampal neurons and decreases the learning and memory function in neonatal rats under hypoxic conditions.

Objective To investigate the effect of in vitro high glucose stimulation on the expression of adiponectin receptor (adipoR) in human kidney proximal tubular cells.Methods The HK-2 cells were cultured in the low glucose DMEM culture medium containing 10% fetal bovine serum until the cells were adherent and 80% confluence. After cultured in the serum-free DMEM for 24 hours, these cells were stimulated with glucose-containing 1mg/ml, 2mg/ml, 4mg / ml, 6mg/ml, 8mg/ml serum-free DMEM for 48 hours. Then RT-PCR and western blot were used to analyze adipoR ( R1, R2) expression levels. The HK-2 cells were cultured respectively in high glucose (4mg/ml) , low glucose (1mg/ml) DMEM culture medium containing 10% fetal bovine serum to cultivate 0h, 12h, 24h, 48h, 72h, 96h, then RT - PCR was applied to analyze adipoR (R1, R2) mRNA expression levels semi-quantitatively. Results Two kinds of adiponectin receptor gene were both expressed in HK-2 cells, and the quantity of gene expression of adipoR1 (0. 63 ±0. 12) was 3. 9 times to adipoR2 (0. 16 ±0.03) , the difference was statistically significant ( P<0. 01). The different concentrations of glucose and different time of high glucose on HK-2 cells had no significant effect ( P>0. 05 ) on adipoR gene expression. Expression of adipoR 1 protein in HK-2 cells was detected by western blot, and it was not affected by glucose concentration ( P>0. 05).Conclusion adi-poR1 and adipoR2 gene were both expressed in HK-2 cells, and the adipoR1 was the major one, which suggested that adipoR1 played a more significant role in kidney disease. The expression of adipoRl/R2 of HK-2 cells was not affected by high glucose concentration.
