The low mass cutoff ( LMCO) is the main weakness of ion trap when it performs tandem mass analysis by collision induced dissociation (CID). LMCO means that some daughter ions of m/ z are less than about 1 / 3 of the m/ z of parent ion could not be detected during the tandem mass spectrometry processing. A new method which can significantly improve the effect of low mass cutoff was proposed and investigated. By simply changing the scan method of digital potential frequency, some low mass ions can be effectively observed during the tandem mass spectrometric experiment. In the experiment, the frequency of the digital ion trapping power and ion activation power were scanned from lower value to higher value, and some lower mass product ions could be detected during CID process. For example, some lower mass ions were observed during the CID of reserpine precursor ion when the frequency of its digital trapping power was scanned from 500 kHz to 560 kHz. The tandem mass spectra of Reserpine ion showed that the experimental results both from this work and the triple quadrupole mass spectrometer were exactly the same.

Cardiovascular disease is a severe threat to human health and life. Among many risk factors of cardiovascular disease, genetic or gene-based ones are drawing more and more attention in recent years. Accumulated evidence has demonstrated that the loss or mutation of ataxia telangiectasia mutated (ATM) gene can result in DNA damage repair dysfunctions, telomere shortening, decreased antioxidant capacity, insulin resistance, increased lipid levels, etc., and thus can promote the occurrence of cardiovascular risk factors, such as aging, atherosclerosis and metabolic syndrome. In this review, we discusses the possible mechanisms between ATM gene and cardiovascular risk factors, which could be helpful to the related research and clinical application.

Objective To evaluate the clinical application of GlideScope~ video laryngoscope in anesthetic endotracheal intubation.Methods Two hundred patients who received surgery under general anesthesia with ASA I or II were involved in this study.One hundred patients were assigned to be intubated with GlideScope~(GS group) and the other 100 with size 3 Macintosh laryngoscope(ML group).The following data were recorded and analyzed: noninvasive blood pressure(NBP),heart rate(HR) at the different time points of intubation process,glottic exposure time,CormarkLehane grade,tracheal intubation time and total intubation attempts. Results The rise of NBP and HR in ML group were significantly higher than those in GS group(P

Objective:To investigate the effects of bFGF on the proliferation of human salivary adenoid cystic carcinoma cell ACC-2 in vitro. Methods:The effect of bFGF on proliferation of ACC-2 cell line was observed by MTT assay; ERK activity was measured by immuno-precipitation; and ERK and I-?B? expressions were assessed by Western blot. Results:bFGF can enhance the proliferation of ACC-2 cell line. Stimulated by bFGF, the proliferation ratio increased significantly. The intracellular ERK activity and p-ERK expression were increased and I-?B? expression was inhibited by different concentrations of bFGF. The above effects of bFGF can be attenuated by MEK inhibitor U0126. Conclusion:bFGF stimulates the proliferation of ACC-2 in the dose dependent manner, which may be due to up-regulating ERK, NF-?B signaling pathway.

Objective To study the influence of total bile acid (TBA) of maternal serum and cord blood on neonatal cardiac function in women with intrahepatic cholestasis of pregnancy (ICP). Methods The concentration of TBA in the maternal peripheral blood and neonatal cord blood were measured by enzyme in 30 women with ICP as patients group matched with 30 normogravidas as control group. The concentration of cardiac troponin Ⅰ (cTnI) in cord blood was detected by monoclonal enzymelinked immunosorbent assay.Fetal left ventricle Tei index was evaluated by color Doppler uhrasonoscope. Results (1) TBA concentration of maternal serum and cord blood at ICP group were significantly higher than that of control group [ (36.0±9.6) μmol/L vs. (3.8±0.9) μmol/L, (10.1±2.0) p, mol/L vs. (5.5±0.4 )μmol/L,P <0.01 ]. TBA concentration of maternal serum at ICP group was significantly higher than that of neonatal cord blood(P<0.01 ). Meanwhile, TBA concentration of maternal serum at control group was significantly lower than that of neonatal cord blood (P<0.01 ). (2) The Tel index of neonatal left ventricle at ICP group were significantly higher than that of control (0.58±0.04 vs. 0.43±0.03, P<0.01 ). (3) The concentration of cTnI from cord blood(0.92±0.23)μg/L at ICP group were obviously higher than that of control group [ (0.52±0.10)μg/L, P<0.01]. (4) The TBA concentration of cord blood at ICP group showed positive correlation with maternal blood TBA, cord blood cTnI and fetal left ventricle Tei index respectively( r=0.769, 0.635, 0.758,P<0.01). In the mean time, the positive correlation between the concentration of cTnI from cord blood and fetal left ventricle Tel index was also observed (r=0.637.P<0.01). Conclusions Left ventricular dysfunction and myocardial injury were shown in the neonates with ICP, which might be associated with with the elevated TBA level of maternal blood. The Tel index of fetal left ventricle could be used as a reliable parameter to monitor cardiac function and the degree of injured myocardial muscles.

Objective To investigate the clinical efficacy of photodynamic therapy using low concentration of photosensitizer, short incubation time and red light source in the treatment of ache. Methods Thirty patients with facial ache were equally randomized into two groups, one group applying 5% 5-aminolevulinic acid (ALA) to the facial lesions on the right side and placebo agent on the left side as control, the other applying the same concentration of ALA to the facial lesions on the left side and placebo agent on the right side as control. The whole face of every subject was irradiated with red light once a week for 4 sessions. The lesions were counted by a dermatologist, sebum production was measured by a sebum meter (SHP88) and pigmentation index by Mexameter MX 18, at the baseline and on week 2, 4, 8 after the last treatment. Adverse effects were also recorded at each visit. Results Two weeks after the last treatment, a sixty percent or more clinical improvement was achieved in the ALA-treated side of 25.9% patients, but no patients experienced sixty or more percent clinical improvement in control side, and the efficacy of ALA was superior to that of the placebo (P<0.05). A significant reduction was noticed in the count of every kind of lesions, including comedo, papules, pustules, cysts/nodules, as well as the total count of these lesions compared with the baseline (all P<0.05); meanwhile, only the pustule count and total count of lesions were decreased in the control side (both P<0.05). Conclusions Both ALA (5%)-PDT and red light-irradiation alone can reduce the number of acne lesions, but the former is more effective than the latter with few side reactions.

Objectives:The present study in vestigated the presence and significance of serum antibody against human myocardial mitochondria in patients with virus myocarditis (VMC) and dilated cardiomyopathy (DCM). 　　Methods:The human myocardial mitochondtia were used as antigen to detect serum autoantibody by immuno-dot blot in 29 VMC patients,24 DCM patients,33 patients with other cardiac (OCD) and 20 healthy blood donor (HBD).The antigen molecular weight was detected by Western blot. 　　Results:①Positive autoantibody against human myocardial mitochordria was found in 41.4% in VMC and 41.7% in DCM patients,which were much higher than 6.1% in OCD or 0% in HBD patients.②Cardiac troponin T was elevated in 43.8% of autoantibody-positive VMC and DCM patients,which was much higher than 12.0% in autoantibody-negative VMC and DCM patients (p＜0.05).③The antigen molecular weight of human myocardial mitochondria was 30KD. 　　Conclusions:①The presence of autoantibody against supports that concept that is responsible for the development of VMC and DCM.Autoantibody is one of the factors that give rise to cardiac injury.The antibody detection may serve as a diagnostic index for VMC and DCM.②The specific antigen is probably human myocardial adenine nucleotide translocator.
