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 investigate the effect of curcumin on the injury in hippocampal neurons and the expression of regulated upon activation nonnal T-cell expressed and secreted (RANTES) in hippocamp during cerebral ischemia/reperfusion (I/R) in rats with spontaneous hypertension (SH).

METHODSMale Wistar-Kyoto (WKY) rats and spontaneous hypertension rats (SHR) were randomly divided into five groups (n = 6): sham group (W-Sham and S-Sham group), ischemia/reperfusion group (W-/R and S/R group), curcumin group (S-Cur group) . Each group was splitted into 5 subgroups of 3 h,12 h, 1 d, 3 d and 7 d according to the time interval before reperfusion. Global brain ischemia/reperfusion model was established by 4-VO method. Hematoxylin-eosin staining (HE staining) was used to observe the vertebral cell morphology in hippocampal CA1 region. Nissl staining was applied to detect the average density of cone cells in hippocampal CA1 region. The expression of RANTES in hippocamp was determined by ELISA. The behavior of the rats was evaluated at 7 days after reperfusion. Results: Compared with the sham group rats, the ability of learning and memory was significantly decreased in ischemia/reperfusion group rats, the number of injured neurons were greatly elevated , the protein expression levels of RANTES was significantly increased (P < 0.05). Compared with W-I/R group rats, the ability of learning and memory in S-I/R group rats was greatly reduced, the number of injured neurons increased extremely, the protein expression level of RANTES was significantly enhanced( P <0.05). The number of injured neurons declined significantly in S-Cur group rats, the ability to learn and remember of these rats was improved and the RANTES protein content decreased significantly (P < 0.05).

CONCLUSIONSHR are more susceptible to ischemia/reperfusion induced hippocampal neuronal injury which may be improved by curcu min. Its underlying mechanism is possibly associated with the inhibition of RANTES protein expression level.

Objective To compare the dosimetric difference on organ at risk (OAR) in intensitymodulated radiotherapy (IMRT) with three-dimensional conformal radiotherapy (3D-CRT) in treatment with cervical carcinoma. Methods 36 cases of cervical cancer patients accepted radiotherapy both on IMRT and 3D-CRT in the same time,clinical target volume (CTV) focused on primary tumor and its lymphatic drainage area.Lymphatic drainage area was determined as follows:1.0 cm extension were added to the margin of pelvic vessels,the obturator lymph nodes region was extended by 1.8 cm from the pelvis inner margin.CTV does not include pelvic tissue. Data of dose distribution and irradiation volume of OAR on the basis of distributing on 45 Gy and 50 Gy were analyzed individually. The margins of planning target volume (PTV) was obtained based on CTV margins by which added 1.0 cm extension in inferior and superior directions,0.7 cm were added in all other directions. Results With the comparison of variety on irradiation volume of organs at risk (OAR) by DVH in both groups,underlying the treatment dose 45 Gy,the individual volume of D30,D40 and D45 were all lesser in IMRT plan than that of 3D-CRT plan. Even on the dose 50 Gy at pelvic wall lymph nodes regions,the volume of OAR was lesser than that in 3D-CRT plan.Conclusion In the radiotherapy of cervical cancer,IMRT should have improved protections for tumor surrounding OAR which has domestic superiority in clinical application.
