Objective To evaluate the effectiveness of using low-frequency repetitive transcranial magnetic stimulation (rTMS) along with donepezil in the rehabilitation of aphasia after cerebral infarction. Methods Fortythree aphasic patients with acute cerebral infarction were assigned into a treatment group or a control group.Both groups received standard basic treatment for acute cerebral infarction.From day 7 on,both groups received oral donepezil hydrochloride (5 mg/d) for 12 consecutive weeks.The treatment group received in addition 2 sessions of low frequency rTMS on the language center of the right hemisphere.The first session started at day 7 after onset,and each session consisted of rTMS on 10 consecutive days (once per day).There was a resting interval of 3 d between the two sessions.The rehabilitation of the aphasia was assessed prior to and after each session,and at the end of the entire 12 weeks of treatment using the western aphasia battery ( WAB ) scoring system and the aphasia quotient (AQ). Results There was no significant difference between the two groups after the first session in terms of the WAB or AQ results.However,the difference in improvement became statistically significant after the second session,as well as at the end of the entire 12 weeks.The average change in AQ was significantly greater in the treatment group. Conclusion Donepezil combined with rTMS early in the acute phase of cerebral infarction is helpful for the rehabilitation of aphasia.

Objective To investigate the effect of palato-pharyngo-plastry on patients with coronary heart disease (CHD) plus obstructive sleep apnea hypopnea syndrome (OSAHS). Methods The 113 OSAHS patients with CHD after palato-pharyngo-plastry from January 2001 to December 2006 were enrolled and followed up. The other 125 cases treated with continuous positive airway pressure (CPAP) were as control group. Results The fundmental factors of CHD including cholesterol, triglyeride, fasting blood glucose and body mass index (BM1) showed no statistical differences between two groups (x2 or t= 4.788, 0.479, 0.541, all P>0.05) . Only the oxyhemoglobin saturation during sleep was higher in study group than in control group [(91.2± 2.5)% vs. (87.6±4.2)%, P=0.046]. The angiography showed that 87 cases (77.0%) retained stable, 24 cases (21.2%) became severe in study group. As compared with control group, there were no statistical differences (both P>0.05). 37 cases (32.7%) in study group and 58 cases (46.4%) in control group who suffered from angina became severe with statistical differences between two groups (x2=4.615, P=0.032). The incidences of myocardial infarction and sudden death were lower in study group (3.5% and 0.8%) and in control group (5.6% and 2.4%), showed no statistical, difterences be tween twogroups. x2=0.571 and 0.495, P>0. 05). Conclusions Compared with CPAP, the palato-pharyngo-plastry can improve oxyhemoglobin saturation and reduce angina symptom, but has no better effect on progress of coronary atherosclerosis and acute coronary disease than CPAP.

Objective To investigate the relationship of carotic intimal-medial thickness (IMT) to high sensitive C-reative protein (hs-CRP) and homocysteine (Hcy) in IGT patients. Methods Seventy patients with IGT were divided into two groups by carotic IMT levels: IMT normal group( IMT≤0.9 mm) and IMT increased group(IMT>0.9 mm). Sixty healthy people were chosen as controls. Blood-lipid, hs-CRP, Hcy, BMI, SBP and DBP were measured in all subjects. Results The Hcy and hs-CRP levels in IGT group were higher than those in controls (P<0.01) ,and also the carotic SBP,DBP,TG and TC levels were higher than those in controls(P<0.05). The Hcy and hs-CRP levels in carotic IMT increased group were higher than those in IMT normal group(P<0.05). The levels of the carotic IMT is positively correlated with hs-CRP(r=0.616, P<0.01), Hcy(r=0.557 ,P<0.01), TC (r=0.351,P<0.05), SBP(r=0.252, P<0.05). Hcy is positively correlated with hs-CRP in IMT increased group (r=0.364, P<0.05). Conclusions Compare with controls, the IMT was higher in IGT patients, and it had the early stage of atherosclerosis (AS). Hcy and hs-CRP levels may predict the early stage of AS in IGT. The high level of Hcy may increase the level of hs-CRP,then lead to the early stage of AS.

Objective:To study the clinicopathologic characteristics and the prognostic factors of triple negative breast cancer,and to study the correlation between clinicopathologic features and EGFR expression.Methods:Clinical characteristics and prognosis of 200 breast cancer patients diagnosed between 1997 and 2004 were reviewed.The paraffin embedded tissues were selected and tissue microarray blocks were made.Immunohistochemical staining was used to evaluate the expression of ER,PR and HER2 for breast cancer molecular type.EGFR expression was evaluated to analyze its correlation with the clinical characteristics and prognosis.Results:Fourty-two cases(21%)of 200 were triple negative breast cancer(TNBC).There was no significant difference between TNBC and non-TNBC in clinicopathologic parameters such as age,tumor size,clinical stage,and lymph node status.However,there was significant difference in histological category and menostasis status between the two groups(P<0.05).Among TNBC,17 0f 42 died during the follow-up(the overall suivival rate was 59.52%),while 26 0f 158 non-TNBC died(the overall survival rate was 83.54%).EGFR was significantly overexpressed in TNBC(69.05%)and it was associated with lymph node status and histological category.Conclusion:Although the incidence of TNBC is low,it has a poorer prognosis than other subtypes.EGFR is highly expressed in TNBC and may serve as a prognostic index and an important therapatic target for breast cancer.
