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.

BACKGROUND: Crucial to the success of fiberoptic awake tracheal intubation is proper preparation of the patient; this technique will work well in most patients when they are quiet and cooperative and have a larynx nonreactive to physical stimuli. We have attempted to ascertain how well these conditions are achieved with a low-dose infusion of propofol, because of its pharmacological profile. METHODS: Thirty patients, physical status by American Society of Anesthesiologists (A. S. A.) I-II, scheduled for oral and maxillofacial surgery, were randomly assigned to receive either propofol infusion 1 mg kg-1 h-1 preceded by a 1 mg kg-1 bolus (Group P) or intravenous fentanyl 1ug kg-1 and midazolam 0.05 mg kg-1 (Group F). These two groups were compared in terms of hemodynamic profile, sedation score, condition for intubation, coughing and swallowing. RESULTS: There were no statistically significant differences in mean arterial blood pressures according to time between two groups. But in Group F, heart rates were significantly increased in immediately after transtracheal injection of lidocaine, immediately before the fiberoscopy was started, 1, 2 minutes after start of fiberoscopy, compared to Group P (p<0.05). The patients in Group P were more sedated than those in Group F (p<0.05) but there were no significant differences in condition for intubation, reflex of coughing and swallowing, duration of fiberoptic intubation. CONCLUSIONS: We conclude that propofol is useful sedative agent in fiberoptic awake intubation with similar efficacy to midazolam and fentanyl but with more profound sedation and stable hemodynamic profile. These represent significant advantages for severe anxious or hypertensive patients and prolonged procedure of intubation.

ObjectiveTo analyze the potential risk factors for relapse and development of epilepsy in patients with benign in-fantile convulsions associated with mild gastroenteritis (BICE).MethodsA total of 264 cases of BICE were recruited. Accord-ing to the frequency of convulsions, the patients were divided into single group (n=134, convulsion once), and multiple group (n=130, convulsions≥2 times). According to convulsion duration, the patients were divided into short-term group (n=186, con-vulsions duration <5 minutes) , and long-term group (n=78, convulsion duration≥5 minutes). The clinical data obtained during hospitalization and follow-up were analyzed.ResultsIn multiple group, 9.23% were relapsed and 6.15% developed epilepsy. In single group, 2.99% were relapsed and 0.75% developed epilepsy. There were signiifcantly different in the rate of relapses and development of epilepsy between two groups (P<0.05). In the long-term group, 12.82% were relapsed and 8.97% developed epi-lepsy. In the short-term group, 3.23% were relapsed and 1.08% developed epilepsy. There were signiifcantly different in the rate of relapses and development of epilepsy between the two groups (P<0.05).ConclusionsThere are the risks of relapse and development of epilepsy in BICE patients. Convulsions≥ 2 times and≥5 minutes may be the risk factors of relapse and devel-opment of epilepsy.

A sensitive and selective method based on gas chromatography hyphenated to mass spectrometry (GC-MS) was developed and validated for the determination of atractylon in rat plasma. Plasma samples were processed by liquid-liquid extraction with ethyl acetate-n-hexane (1:1, v/v) using acetophenone as an internal standard (IS). Analytes were determined in selective ion monitoring (SIM) mode using target ions at m/z 108.1 for atractylon and m/z 105.1 for acetophenone. The calibration curve was linear over the concentration range of 10-1000 ng/mL with lower limit of quantification of 10 ng/mL. The intra- and inter-day precision variations were not more than 10.4% and 9.6%, respectively, whilst accuracy values ranged from -6.5% to 4.9%. Extraction recovery of the assay was satisfactory. This method was suc-cessfully applied to quantification and pharmacokinetic study of atractylon in rat plasma after in-tragastric administration of Atractylodis extract.
