Triple-negative breast cancer(TNBC)is a special subtype of breast cancer which is invalid to endocrine therapy.Anti-Her2 targeted therapies such as herceptin and lapatinib are not suitable to TNBC.At present,conventional chemotherapy is the only way for the medical therapy of TNBC.Thus,searching for novel therapeutic agents for TNBC is one of hot researches of breast cancer.New targeted therapy drugs such as PARP-1 inhibitors,EGFR inhibitors,CXCR4 inhibitors,anti-angiogenesis drugs,Src tyrosine kinase inhibitor,and mTOR inhibitor are being researched.

Objective To compare the cerebral vessels stenosis in acute cerebral infarction patients with or without diabetes mellitus.Methods Using case-control study,51 acute cerebral infarction patients with diabetes mellitus and 64 patients without diabetes mellitus were checked by digital subtraction angiography(DSA).The condition of stenosis and obstruct of vessels in intracranial and extracranial were compared.Results Stenosis of intracranial arteries was frequent in both two groups.The main involved arteries included M1 and M2 segments of middle cerebral artery and external cranial segment of internal carotid artery.The rate of cerebrolvascular abnormality in the patients with diabetes mellitus(84.31%) was higher than that in the patients without diabetes mellitus(70.31%).Stenosis of multiple arteries(52.94%),arteriostenosis combined with ulcer or plaque(39.21%) and collateral circulation development(11.63%) were found in diabetic patients,while the rates were 18.75%,17.19% and 31.11%,repectively,in non-diabetic patients.These differences between two groups were statistical significances(all P

BACKGROUND: Many animal and clinical studies have reported that the safe and effective usage of umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) transplantation for treatment of neurological genetic diseases.OBJECTIVE: To investigate the feasibility and effect of UCB-MSCs transplantation in the treatment of spinal muscular atrophy (SMA).METHODS: A child admitted at January 2010 had been confirmed as having SMA, and drug and rehabilitation therapies were invalid. Then, the child received UCB-MSCs transplantation via the first intravenous infusion and three times of subarachnoid injection, once a week, (4-6)×107 cells once and four times as a course. Neurological physical examination, biochemical test, muscle enzymes detection, FIM scoring and electromyography (EMG) examination were conducted. RESULTS AND CONCLUSION: Compared with prior to transplantation, the level of muscle enzymes decreased, FIM scores were increased from 68 to 93 points, EMG results showed that the motor units with re-contraction in each 10.0 ms were increased that the motor function was improved, the lower extremity muscle strength elevated, and the self-care ability was improved in the SMA child at 6 months after transplantation. During the 10-month follow-up, the child had no adverse effects. It is indicated that UCB-MSCs transplantation is effective to treat SMA, and the neurological function has a remarkable restoration.

Objective To characterize the clinical features and assess the role of surgery in posterior cortex epilepsy. Methods A retrospective analysis of clinical data was performed in 43 patients with posterior cortex epilepsy. The diagnosis Was established by means of a standard presurgical evaluation, including ictal semiology, MRI, interictal and ictal scalp video-EEG, and additional intracranial EEG monitoring in selected cases. Results The 43 patients included 11 parietal lobe epilepsy, 13 occipital lobe epilepsy, and 19 patients with seizures originating from other part of posterior cortex. Thirty-three patients (76.7%)experienced at least one type of aura, such as visual aura, somatosensory aura, dizziness and so on. The common ictal manifestations included deviation, automatisms, tonic posture and so on. Intracranial EEG monitoring was preformed in 22 selected cases. Transient contralateral hemiparesis occurred in 2 patients, mixed aphasia in 1 patient, and they recovered in 3 weeks after surgery. Visual and visual field deficits were observed in 5 patients, and they did not fully recovered. All patients were followed-up 1 to 5 years, and 27(62.8%)became seizure free (Engel' S I class). Conclusions Some of the specific auras or ictal manifestations may indicate posterior cortex epilepsy. Favorable surgical outcome has been achieved in many of the patients.

To compare the differences between Hengshanhuangqi (HH) and Chuanhuangqi (CH) at molecular level, 1H NMR based plant metabolomics approach was used to reveal the chemical difference between HH and CH. Then, the contents of astragaloside IV and calycosin-7-O-beta-D-glucoside, the marker compounds specified in China Pharmacopoeia, were determined. In addition, the ITS2 fragments of HH and CH were sequenced. Twenty-three metabolites were identified in the 1H NMR spectrum, and the principal component analysis showed CH and HH could be separated clearly. HH contained more aspartic acid, GABA, citric acid, astragaloside IV and calycosin-7-O-beta-D-glucoside, while CH contained more threonine, alanine, acetic acid, choline, arginine, fructose and sucrose. And the astragaloside IV is almost undetectable in CH. In addition, the ITS2 fragment sequences of HH and CH were different at eight bases. Thus, the HH and CH showed significant differences chemically and genetically.

Objective To reveal the influential factors on scalp electroencephalogram (EEG)recording and provide valuable information for localization of the epileptic focus by analyzing the characteristics of spikes with continuous focal periodic discharges on scalp and cortical EEG. Methods Five patients with refractory epilepsy who had low amplitude spikes with continuous focal periodic discharges on interictal scalp EEG were studied. Intracranial EEG recording was also performed in patients. The amplitudes of spikes and cortical areas of spike-wave foci were measured by DaVinci system. Patterns of continuous periodic activity were determined by autocorrelograms,power spectral density and coherence analysis using Matlab and Spike2 software.T-test was employed to compare the mean amplitudes of spikes on the scalp and cortical EEG.Results The amplitudes of spikes recorded on scalp EEG of the 5 patients were:(22.2±4.8),(30.4±7.1),(20.7±3.2),(58.4±10.1),(23.4±3.9) μV.The amplitudes of spikes recorded on cortical EEG of the 5 patients were:(1253.8 ± 199.3),(806.5 ± 161.4),( 1585.7 ±305.7),(922.5 ± 140.6),(736.8 ±70.9) μV.The amplitudes of spikes on scalp EEG were significantly higher than those on cortical EEG ( t =6.394,P ＜ 0.05 ).The cortical areas of spike-wave foci of the 5 patients were:4.0,6.0,3.5,5.5,6.5 cm2.Power spectral density and autocorrelugrams showed 1-3 Hz oscillations on the cortical of spike-wave foci. Cross-correlation and coherence analysis showed synchronization of electrical activity in two contacts of intracranial electrodes. Conclusion The low amplitude spikes with continuous focal periodic discharges on interictal scalp EEG provide valuable information for localization of the epileptic focus.
