Objective To explore the effect of obstructive sleep apnea syndrome (OSAS), OSAS-like intermittent hypoxia (IH)on the expression levels of P-YAP and YAP in A549 lung cancer cell lines. Methods A549 cells were treated with IH exposure ( exposed to 5%O2 for 300 seconds and 21%O2 for 300 seconds) for 1, 3 and 6 h (IH1, IH3, IH6) or normoxia exposure (N group). Quantificational real-time PCR was used to measure the mRNA expression levels of YAP. Western blot assay was used to detect the protein expression levels of YAP and P-YAP. Results The mRNA expression levels of YAP were significantly increased with the increase of IH exposure time points in IH1 (2.50±0.18), IH3 (4.07±0.25) and IH6 (9.18 ± 0.58) groups than those in N group (1.00 ± 0.01) (all P<0.05). The protein expression levels of YAP were significantly increased with the increase of IH exposure time points in IH1, IH3 and IH6 groups than those in N group. The protein expression levels of P-YAP were significantly decreased with the increase of IH exposure time points in IH 1, IH3 and IH6 groups than those in N group. Conclusion YAP cell signaling plays an important role in the process of OSAS-like IH induced tumor development.

Objective:To verify and discuss the consistency and applicability of the semi empirical formula and Monte Carlo simulation method in the radiation shielding calculation for high energy synchrotron radiation source.Methods:The semi empirical formula and Monte Carlo simulation were used to calculate the ambient dose equivalent outside of the shielding.Results:The ratio of Jenkins semi empirical formula result to Monte Carlo simulation result was 111%-153%. The ratio of Sakano semi empirical formula result to Monte Carlo simulation result was 201%.Conclusions:For a single shielding material, the semi empirical formula can be simple and conservative to complete the shielding calculation for high-energy electron accelerator. For a variety of shielding materials, Monte Carlo simulation method should be used.

Objective To explore the therapeutic effects and dose of Topiramate(TPM)in children with Tourette syndrome(TS).Me-thods Seventy-nine children with TS were given oral TPM,which were treated with Topiramate [0.5-3.0 mg/(kg?d),twice a day].The therapeutic effects were assessed using Yale Global Tic Severity Scale(YGTSS)before and 3 months after treatment and the side-effects of the drugs were observed.Results The differences of YGTSS scores before and after treatment,motertic score(19.63?3.09 vs 5.05?1.74),vocaltic score[(18.95?2.56)vs(4.82?1.94)],global scole score[(24.21?5.89)vs(10.42?3.69)],severity score[(62.21?5.81)vs(22.26?4.81)],there were significant differences of every score of YGTSS between before and after treatment(Pa

Multi-walled carbon nanotubes-tungsten oxide (MWCNTs-WOx) nanocomposites were fabricated on glassy carbon electrode (GCE) through a simple electrodeposition method,in which WOx were fabricated on MWCNTs. The morphology and constitution were characterized by field emission scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS). Electrochemical characterization of modified electrode was done by electrochemical impedance spectroscopy (EIS). The cyclic voltammogram (CV)method was adopted to investigate the electrochemical behavior of dopamine (DA) on MWCNTs-WOx-modified glassy carbon electrode, and a new detection method for DA was developed by differential pulse voltammetry (DPV). The results showed that MWCNTs-WOx nanocomposites had obvious electrocatalytic effect on DA in phosphate buffer solution (pH=6.5). Under the optimized experimental conditions, the DA peak current demonstrated a good linear relationship with concentration in the range of 0.05-1.00 mmol/L, and the detection limit was 17 μmol/L(S/N=3). Effects of different experimental parameters on the response current of the modified electrode were investigated,and it was found that the prepared electrochemical sensor displayed good reproducibility,high selectivity and strong anti-interference ability. UA did not interfere with the detection of DA. A new electrochemical method for the quantitative determination of DA was established and successfully applied to the determination of dopamine hydrochloride injection samples.

Objective To explore the maternal-fetal transmission patterns and interventional methods of syphilis during pregnancy.Methods A total of 847 cases of syphilis in pregnancy confirmed by rapid plasma reagin test(RPR)and treponema pallidum hemoagglutination test(TPHA)were treated with procaine benzylpenieillin intramuscular injection,and with erythrocin oral medication if hypersensitive to benzylpenicillin.Eight hundred forty seven cases of syphilis during pregnancy were followed up for pregnancy outcomes.And their newborn babies were tested using the RPR.The newborns with positive results were given intervention and followed up until 24 months after birth.Results(1)A total of 733 cases among the total 847 have given birth to living-babies,in which 626 cases were tested using RPR,and the positive rate was 55.1%(345/626).(2)The RPR positive rate,neonatal mortality,preterm birth rate and low birth rate in the newborn of mothers with an RPR titer higher than or at 1:8 were higher than those of mothers with an RPR titer lower than 1:8(P

Objective To explore the relationship between polymorphism of 5-hydroxy tryptamine 2A(5-HT2A)receptor T102C gene and post-stroke depression(PSD),and investigate the heredity-related pathogenesis of PSD.Methods The polymerase chain reaction and restriction fragment length polymorphism(PCR-RFLP)method was applied to test the allele frequencies and genotype of 5-HT2A receptor T102C gene in 97 patients with PSD and 72 patients without depression after stroke.Results The frequency of mutant C allele in patients with PSD was significantly lower than that in patients without depression(P＜0.05),and the frequency of homozygote C/C genotype in patients with PSD was also obviously lower than that in patients without depression(P＜0.05).Conclusion The 5-HT2A receptor T102C gene may be the susceptibility gene of PSD and C allele may be the protective factor of subjects suffering from PSD.

Objective To investigate the rehabilitation promoting factors in stroke patients and to provide references for the design and implementation of effective intervention for rehabilitation of stroke patients.Methods In-depth interviews were conducted among eight stroke patients,and interview data were collected and analyzed.Results Five themes were identified through analysis and classification of the interview data:practical rehabilitation goals,effective rehabilitation training behaviors,overcoming abandonment behaviors and negative emotions,suitable support system,and proper self-adjustment.Conclusion The rehabilitation promoting factors for stroke patients are performing effective rehabilitation training towards effective rehabilitation goals.In this process,patients need to rely on appropriate social support and patients' self-adjustment to overcome abandonment behaviors and negative emotions.These factors form a force to promote rehabilitation during the process of rehabilitation.

OBJECTIVETo observe the effect of Kangxin Capsule (KXC) on the expression of nerve growth factor (NGF) as well as the morphology and amount of nerve synapse in the cortical parietal lobe and hippocampus CA, area of vascular dementia ( VD) model rats.

METHODSThe model rats of VD made by photochemical reaction technique were randomly divided into five groups: the model group (MG), the high-dose, middle-dose and low-dose KXC groups (HDG, MDG and LDG), and the Western medicine hydergin control group (WMG). They were treated respectively with distilled water, high, middle and low dosage of KXC suspended liquid, and hydergin for a month. Besides, a blank group consisting of normal (non-model) rats was set up for control (CG). The ultrastructure of nerve synapse in the cortical parietal lobe and hippocampus CA1 area of the rats were observed and its density estimated. The condition of NGF positive neurons in the above-mentioned two regions were also observed by immunohistochemical stain.

RESULTSAll the KXC or hydergin treated groups demonstrated a normal amount of nerve synapse with integral structure in the cortical parietal lobe and hippocampus CA, area, which approached that in the CG and was superior to that in the MG. Also, the NGF positive neuron in all the treated groups was much more than that in MG with significant difference ( P<0.01), approaching to that in the CG.

CONCLUSIONKXC could elevate the expression of NGF in the cortical parietal lobe and hippocampus CA, area, preserve the number and morphology of synapse, thus to protect the function of nerve system from ischemic injury.
