Aim To investigate the cardioprotective effects and the possible mechanism of trimetazidine in the risky areas during late reperfusion after acute myocardial infarction in canine.Methods Twenty-four adult dogs were randomized into three groups:sham operation group(n=8),late reperfusion group(LR,n=8),late reperfusion after trimetazidine treatment group(LR+TMZ,n=8).Physiological saline was orally given in the sham operation group and LR group and trimetazidine(2 mg?kg-1?d-1) in the LR+TMZ group for fourteen days.After that later,all chests were opened and coronary areteries were exposed.Exceptly shame operation group,the late reperfusion of acute myocardial infarction model was made by ligating the coronary for 10 h,followed by reperfusion of 10 h.Apoptotic index were detected by TUNEL.The Bcl-2,Bax,Cytochrome C and apoptosis-inducing factor(AIF) proteins were detected by immunohistochemistry.Results Compared with those of LR group,myocardial apoptotic index and the expression of Bax,Cytochrome C and AIF proteins in LR+TMZ decreased significantly(all P

Objective To study the possible effects of transcranial magnetic stimulation (TMS)on the sleep structure of the patients with Parkinson's disease.Methods Fifteen PD patients attending an outpatient Movement Disorders Unit at Department of Neurology,Cerrahpasa Faculty of Medicine,between September 2006 and December 2007 were included in the study.All patients had received TMS treatment.The stimuli were delivered through a circular coil with a 12 cm diameter and a 2.0 T peak magnetic field.They underwent clinical evaluation and polys omnographic (PSG) evaluation before and after a minimum treatment period of 10 days with TMS.Results The mean UPDRS score was significantly decreased after TMS(before treatment,38.83?16.72;after treatment,25.09?11.10).PSG revealed that administration of TMS resulted in significant decrease in mean Sleep latency[before treatment,(53.50?46.40)min;after treatment,(30.43?23.91)min].Slow wave (stage 3+4) was found in somes patients after treatment.But here was a trend towards an decrease in Percentage of stage 1,REM latency and REM sleep without significance.Conclusion This study demonstrates that motor symptom of PD was improved and Sleep latency was decreased by TMS.Sleep structure was not changed before and after TMS treatment.

Objective To investigate the androgen-like effects of Cordyceps sinensis (CS) and its impact on the radiosensitivity of VCaP prostate cancer cells.Methods The hormone levels and weight index of reproductive organs in mice were determined after gavage with CS.Clonogenic assay was performed to determine the impact of CS on the radiosensitivity of VCaP cells.The 3-(4,5-dimethylthiazol-2-yl)-5 (3-carboxymethonyphenol)-2-(4-sulfophenyl)-2H-tetrazolium assay,flow cytometry,and tumor xenografts in nude mice were performed to determine the effects of CS on the proliferation of VCaP cells (androgen receptor-positive) and PC-3 cells (androgen receptor-negative) in vitro and in vivo.Serum prostate-specific antigen (PSA) levels in nude mice were evaluated.Data were analyzed by one-way analysis of variance or ttest.Results The testosterone level and weight of prostate in mice were significantly higher in the CS group than in the control group ((8.28± 1.94) vs.(2.08± 1.24) ng/ml,P=0.023;(0.53±0.04) vs.(0.31 ± 0.04) mg/g,P =0.006).The radiosensitivity enhancement ratio (ratio of D0 values) was 0.80.The viability of VCaP cells was significantly higher in the CS group than in the control group (1.32 ± 0.07 vs.0.66 ±0.02,P=0.000),and colony forming efficiency was significantly enhanced in the CS group than in the control group (57.0％ ± 1.9％ vs.47.0％ ± 0.6％,P =0.005).VCaP tumor xenografts in nude mice were inclined to grow faster in the CS group than in the control group,and the serum PSA level in the CS group was significantly higher than that in the control group ((0.66 ± 0.04) vs.(0.26 ±0.06) ng/ml,P =0.000).However,CS had no effect on PC-3 cells at the working concentration.Conclusions CS has the androgen-like effects.It may also promote the proliferation and reduce the radiosensitivity of androgen receptor-positive VCaP cells.

Objective:To investigate the clinical significance of coagulation function related indicators in the prognosis of non-small cell lung cancer.Methods:The clinical data of 248 patients with non-small cell lung cancer from June 2014 to December 2017 in the Department of Oncology, Beijing Hospital of Traditional Chinese Medicine, Capital Medical University, were retrospectively analyzed. The receiver operating characteristic (ROC) curve was used to determine the best cutoff values of prognostic indicators,the Cox regression model was used for multivariate analysis, and the Kaplan-Meier method was used for survival analysis.Results:ROC curve analysis showed that the best cutoff values for D-dimer (D-D), fibrinogen (FIB) and prothrombin time (PT)were 0.18 mg/L, 4.25 g/L and 12.0 s, respectively. Cox multivariate regression analysis showed that increased expression of D-D ( HR=1.197, 95% CI 1.100-1.303), PT ( HR=1.111, 95% CI 1.049-1.176) and FIB ( HR=1.510, 95% CI 1.276-1.788) were risk factors for the prognosis of non-small cell lung cancer ( P<0.001). Kaplan-Meier survival analysis results showed that the overall survival in the high expression group of D-D, FIB and PT was shorter than in of the low expression group ( P<0.001). Conclusion:D-D, PT and FIB are independent factors affecting the prognosis of non-small cell lung cancer.

BACKGROUND:Neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine can induce the clinical, biochemical and pathological characteristics similar to those observed in primary Parkinson’s disease. OBJECTIVE:To observe the effects of repetitive transcranial magnetic stimulation on the proliferation of endogenous neural stem cells of Parkinson’s disease model mice and the mood change.
METHODS:A total of 72 male C57BL/6J mice were randomly divided into four groups:normal saline group, Parkinson’s disease model group (model group), sham-repetitive transcranial magnetic stimulation group (sham group) and repetitive transcranial magnetic stimulation group. The mice received 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine injection×4 to establish acute Parkinson’s disease models. The mice in the normal saline group were injected the same volume saline. And 24 hours after the last injection of 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine, the mice in the repetitive transcranial magnetic stimulation group received five trains of repetitive transcranial magnetic stimulation, 1 Hz for 25 seconds, at an intensity of 1 Tesla daily for 1, 3, 7 consecutive days. Sham group mice were not exposed to the magnetic field. No treatment was performed in the mice of model group. The mood change was evaluated using the elevated-plus maze testing before and after repetitive transcranial magnetic stimulation treatment. The change in expression of nestin in the subventricular zone was observed by using immunohistochemical technique.
RESULTS AND CONCLUSION:(1) Elevated-plus maze testing:There was no statistical significance about percentage of opening arm time accounting for total time among groups and at different time points in each group, but after stimulation, the percentage of opening arm time accounting for total time showed a declined tendency. (2) The results of nestin immunohistochemical staining:Compared to the normal saline group, the number of nestin-positive cells of the model group was increased at days 3 and 7, and there was no statistical significance in the number of nestin-positive cells between model group and sham group;Compared to the sham group and model group, the number of nestin-positive cells of repetitive transcranial magnetic stimulation group were evidently increased;The proliferation of endogenous neural stem cells was time-dependent, endogenous neural stem cells exhibited outward migration gradual y along the certain way, and some cells were able to migrate to the corpus cal osum at day 3, and even to the cerebral cortex at day 7. Repetitive transcranial magnetic stimulation can promote the endogenous neural stem cells in a time-depended manner.

Objective To observe any differences in motor cortex excitability between Parkinson's disease (PD)patients and patients with multiple system atrophy (MSA) and to explore whether motor evoked potentials (MEPs) can be used as an electrophysiological indicator for differentiating the 2 diseases.Methods Thirty-four PD patients, 22 MSA patients and 15 age- and sex-matched healthy control subjeets were included in this study. Relaxed motor thresholds (RMTs), central motor conduction time (CMCTs) and MEP amplitudes (AMPs) were recorded in all three groups. The relationships of RMT, CMCT and AMP with the severity of the disease were observed.Results Average RMT in the PD group was significantly lower than that in the MSA and control groups. Average RMT in the MSA group was also significantly lower than that in the control group. There was no significant difference among the three groups with regard to CMCT. AMP in the PD group was significantly higher on average than in the MSA and control groups, but there was no significant difference between the MSA and control groups. RMT decreased and CMCT shortened progressively with the severity of the disease in the PD group, but not in the MSA group.Conclusions There were differences in motor cortex excitability between PD patients and MSA patients. MEP RMTs and CMCTs may be valuable for identifying PD and MSAc but the clinical significance of the amplitude differences remains to be further explored.

Objective Using shotgun mass spectrometry to detect proteins probably contained in bone marrow stromal cells(BMSCs) conditioned medium. MethodsMixed with BMSCs conditioned medium was divided into two parts which is(>5kD and <5kD) by means of ultrafiltration. The two parts were used to culture neural stem cells(NSCs) separately, and the proportions of neurons, astrocytes and oligodendrocytes in the offsprings of NSCs were calculated, then the effective part that could regulate the differentiation of NSCs was detected by Shotgun mass spectrometry. Results The BMSCs conditioned medium which is >5kD could promote the NSCs differentiate into more neurons and oligodendrocytes. The SDS-PAGE of this part showed that the most proteins were above 14kD, then the protein bands were enzymed. In total, 456 proteins were identified by Shotgun mass spectrometry after all the protein bands were enzymed, there were 154 similar proteins, 17 hypothetical proteins and 56 unknown proteins. And in the rest of 229 proteins, most of them were cytoskeletal proteins, secreted proteins, signal transduction proteins, enzymes, transporter and so on. Conclusion Many proteins secreted by BMSCs could regulate the differentiation of NSCs so as to prove the protein components probably existed in the BMSCs conditioned medium.
