OBJECTIVE: To evaluate the osteogenetic character and repairing maxillary sinus superior wall fractures capability of calcium phosphate cement (CPC) before and after combined with recombinant human bone morphogenetie protein-7(rhBMP-7). METHOD: A 10 mmX5 mm bone defect in the maxillary sinus superior wall was induced by surgery in all 24 New Zealand white rabbits. These 24 rabbits were randomly divided into two groups. The defects were repaired with CPC group (n = 12) and CPC/rhBMP-7 group (n = 12). The osteogenesis of bone defect was monitored by gro'ss observation, histological examination, observation under scanning electron microscope and measurement of ALP activity at 6 and 12 weeks after the implantation. RESULT: In group CPC,new bone was found to form slowly and little by little. In group CPC/rhBMP-7, however, new bone was observed to form early and massively. The ALP activity in group CPC showed significant statistical difference with that of group CPC/rhBMP-7 (P < 0.05). CONCLUSION The CPC/rhBMP-7 composite has osteoconductibility and osteoinductibility, comparing the use of CPC/rhBMP-7 with CPC for the repair of orbital fracture, the former show obvious advantage repairing ability in maxillary sinus superior wall defect.

Objective To investigate the effects of neutrophil gelatinase associated lipocalin(NGAL) on renal tubular epithelial cells apoptosis and apoptosis-regulated protein fas,bcl-2 in rat renal ischemia reperfusion injury (IRI).Methods Renal IRI models of rats were established.Rats were randomly divided into 3 groups,including control group,IRI model group and NGAL group.The pathological change of kidney tissue was investigated by hemotoxylin-eosin staining.Renal tubular epithelial cells apoptosis was detected by TUNEL method.Expression of fas and bcl-2 was measured by real-time PCR and Western blotting.Results Compared with IRI model group,NGAL group showed a decreased number of renal tubular epithelial cells apoptosis [(8.6±3.4)/HP vs (20.8±3.7)/HP,P＜0.05],down-regulated fas mRNA (2.34±0.51 vs 6.84±2.34,P＜ 0.05),fas protein (0.65±0.05 vs 0.95±0.08,P＜0.05) and up-regulated bcl-2 protein (0.33±0.05 vs 0.24±0.03,P＜0.05),but the bcl-2 mRNA had no significant change.Conclusion NGAL can protect renal tubular epithelial cells in renal IRI,which may be associated with decreasing cell apoptosis and adjusting protein expression by apoptosis-regulated cytokines.

Objective To investigate the effect of tandem mass spectrometry and gas chromatography-mass spectrometry to make prenatal diagnosis of methylmalonic acidemia (MMA) by detecting organic acid and acylcarnitine in amniotic fluid.Methods From October 11,2007 to December 20,2014,131 pregnant women with MMA proband received prenatal diagnosis of MMA in Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine (case group).Another 120 cases of pregnant women for conventional prenatal diagnosis at the same period were as control group.The pregnant women of two groups had the amniocentesis at 16 to 20 weeks of gestation.The levels of propionylcarnitine(C3) and acetylcarnitine(C2)in amniotic fluid were detected by tandem mass spectrometry.The methylmalonic acid and methylcitrate acid were detected by gas chromatography-mass spectrometry.MMA gene of cells in amniotic fluid of eighty fetuses with proband clearly diagnosed were detected by gene testing.Data were analyzed by Wilcoxon test.Results In case group,29 fetuses were found positive for higher level of C3,C3/C2,methylmalonic acid and methylcitrate acid compared with normal reference value,and the detected rate of fetal MMA was 22.1％(29/131).The levels of C3 and C3 / C2 in amniotic fluid of these 29 cases were higher than those in control group[8.13(2.42-16.70) vs 1.04(0.52-3.40) μmol/L,Z =-8.313; 0.77(0.30-1.79) vs 0.10(0.05-0.22),Z=-8.374; P ＜ 0.05 respectively].The levels of methylmalonic acid and methylcitrate acid were also higher[9.13(1.68-61.78) vs 0.00(0.00-1.31) mmol/mol Crea,Z=-11.348; 0.58(0.00-1.90) vs 0.05(0.00-0.52) mmol/mol Crea,Z=-6.632,P ＜ 0.05 respectively].For the other 102 cases in case group,the levels of C3,C3/C2,methylmalonic acid and methylcitrate acid were not higher than normal reference value,and were similar to those in control group (P ＞ 0.05); while they were lower than those of positive MMA fetuses (all P ＜ 0.05).Among 29 positive fetuses,16 fetuses were detected MMA gene,five were diagnosed as MUT forms of MMA and 11 were MMACHC forms of MMA.In 102 MMA negative fetuses,64 fetuses were detected MMA gene,44 were found one mutant site and 20 were found no gene mutation.The coincidence rate between gene detecting and mass spectrometry was 100％(80/80).Conclusions Mass spectrometry could be used to measure the C3,methylmalonic acid and methylcitrate acid levels in amniotic fluid of pregnant women with MMA proband to make prenatal diagnosis.

An on-line solid phase extraction ( SPE ) coupled with HPLC-MS/MS method was developed to determine S-ammuxetine and R-ammuxetine in rat plasma. The sample preparation consisted of the following steps:A protein precipitation extraction used methanol and acetonitrile ( 50:50 , V/V ); an on-line SPE treatment to remove most matrixes in plasma;an enrichment and separation step used a C18 analytical column. S-and R-ammuxetine were determined by tandem mass spectrometry. The SPE column was a Retain PEP Javelin (10 mm × 2. 1 mm × 5 μm), while the chromatographic separation was achieved using a ZORBAX SB-C18 (50 mm × 2. 1 mm × 3. 5 μm) analytical column with an isocratic mobile phase composed of acetonitrile-water-formic acid (40:60:0. 1, V/V/V, 0. 3 mL/min). The selected reaction monitoring mode of the positive ion was performed and the precursor to the product ion transitions of m/z 292 . 1/154 . 0 and m/z 260. 4/116. 2 were used to measure S-ammuxetine, R-ammuxetine and internal standard (propranolol). The method was linear over a concentration range from 0 . 2 to 1000 μg/L with the correlation coefficients of 0 . 9903 and 0 . 9951 . The average intra-day precision values were 1 . 2% -12 . 0% for S-ammuxetine and 0. 4%-11. 2% for R-ammuxetine, respectively. The average recoveries were 94. 2%-101. 6% for S-ammuxetine and 94. 3% -109. 4% for R-ammuxetine. Compared to the literature, the sensitivity of this method increased dramatically. The present method has been successfully applied to the preclinical rat research of ammuxetine isomers following intragastric administration.
