Objective: To understand the cognition status for risk factors and early symptoms of stroke via face to face questionnaire survey in 336 in-hospital patients with atrial ifbrillation (AF).
Methods: A face to face questionnaire survey was conducted by uniformly trained investigators in 336 AF patients who were admitted in our hospital more than 3 days from 2014-04-01 to 2014-10-01.
Results: There were 300/336 AF patients ifnished the questionnaire and among them 131 (43.7%) patients know that AF may increase the risk of stroke and 169 (56.3%) patients unknown or uncertain. There were 41.3%-79.3% patients having cognition for early symptoms of stroke and only 25.3% (76/300) patients may identify all 5 early signs of stroke.
Conclusion: In our research, AF patients had poor cognition for the risk and early signs of stroke. Medical professional should intensify the propaganda and education for stroke prevention.

Background and purpose:Tumor necrosis factor related apoptosis-inducing ligand (TRAIL) is a death receptor ligand that can induce apoptosis in a variety of cancer cell lines, but not all cancer cells . Past studies suggested that some chemotherapeutic drugs intensified the sensitivity of TRAIL induced apoptosis.We investigated the effect and potential mechanism of combined paclitaxel and TRAIL on apoptosis of human gastric cancer cell in vitro. Methods:SGC7901 cells were cultured with paclitaxel at different concentrations(1,5,10,20,40 ?g/ml) and different time(12,24,36,48 hr), methyl thiazolyl tetrazolium (MTT) assay was used to measure the anticancer activity of paclitaxel.The ability of TRAIL alone,paclitaxel alone and TRAIL in combination with paclitaxel to induce apoptosis was measured by a flow cytometer. Expression of DR4,DR5, DcR1,DcR2,Caspase-8 and Bcl-2 mRNA was examined by RT-PCR.Results:The apoptosis rates of control group(C group),paclitaxel group(P group),TRAIL group (T group)and combination group(T+P)in 24 hr were 2.09%,10.65%,7.79% and 24.51%, respectively. The apoptosis rate in T+P group was significantly higher than that in C group, T group and P group(P

The levels of C-reactive protein(CRP),adenosine deaminase(ADA),total cholesterol (TC),lactate dehydrogenase(LDH),carcinoembryonic antigen(CEA),ferritin(Fer),β2-microglobulin (β2-MG),alpha-fetoprotdn(AFP),carbohydrate anfigen12-5(CA125),carbohydrate antigen19-9(CAl99),carbohydrate antigen15-3(CA153),eyfra211(CY211)and neuron specific enolase(NSE)were detected by automatic chemistry analyzer or electrogenerated chemiluminescence analyzer in pleural and peritoneal exudates from 48 cases oftuberculosis and 82 cases of malignant tumors.The levels of CRP,ADA and β2-MG in tuberculotic exudates were higher than those in malignant exudates(P<0.01).However,the levels of TC,LDH,CEA,Fer,CA153,CY211,NSE,AFP,CA125 and CA199 in malignant exudates were higher than those in tuberculotic exudates(P<0.01).Combined determination of CRP,ADA,TC,LDH,CEA,Fer,and β2-MG in pleural and peritoneal exudates are of value in differentiation of tuberculosis from malignant exudates.Combined determination of CA153.CY211 and NSE in pleural effusions and AFP,CA125 and CA199 in peritoneal effusions can improve the semitivity and specificity of diagnosis for malignant exudates.

Objective To study the visual attention of mild cognitive impairment patients (MCI)by eyes movement training. Meathods 48 mild cognitive impairment patients were divided into eye movement training group,finger training group and untreated control group by single-blind randomized block method. Then they were trained respectively three months. Event-related potentials (ERPs) were used to measure the face recognition of them before and after training. The amplitude and latency of P3b elicited by target stimuli and P3a elicited by new stimuli of the three said groups were compared and contrasted. Results After training,the amplitude of P1 elicted by novelty stimulus were larger in eye movement training group( (6.78 ± 1.55 ) μV) and in finger training group ( ( 5.43 ± 1.47 ) μV) than untreated control group ( ( 3.09 ± 0.98 ) μV) significantly, especially in the frontal area. The amplitude of P1 elicted by target stimulus were larger in eye movement training group( (6.75 ±2.01 ) μV)than in finger training group( (4.12 ± 1.33 )μV)and untreated control group( (3.45 ± 1.01 )μV)significantly, especially in the frontal area. The amplitude of P3a were larger in eye movement training group( ( 10. 19 ± 3.09)μV ) than in finger training group ( ( 7.57 ± 2.66 ) μV ) and untreated control group ( ( 6.06 ± 2.03 ) μV ) (P ＜ 0.05,P＜0.05) significantly,especially in the frontal area. The latency of P3a were earlier in eye movement training group( (390.67 ±55.03 ) ms) compared to finger training group( (428.55 ± 48.68 ) ms) and untreated control group( (435.89 ± 59.21 )ms)significantly, especially in the frontal region and central parietal area. Conclusion Eyes movement can improve the MCI patients' non-selective attention function, especially in frontal area.The finger execrises have no significant effect on visual attention.

Objective To evaluate the modified Physical and Operative Severity Score for the Enumera-tion of Mortality and Morbidity (POSSUM) in predicting the postoperative morbidity in patients with fractures of the pelvis and acetabulum. Methods The clinical data of 94 patients with pelvic and acetabular fractures were retrospectively analyzed. Their postoperative prognosis during hospital stay was evaluated with the POSSUM scoring system modified according to the features of orthopedics and pelvic and acetabular fractures. The peritoneum in-fection in the severity index of operation was replaced by operative approach, the several operations at one time by operative duration, and the cancer by the associated injury. The size and type of operation were made into 4 grades with corresponding orthopedic scores. The scores were compared between the complication group and the non-complication group. The receiver operator characteristic (ROC) curve was drawn to describe the coincidence degree, define the cut points, and evaluate its predicting capability. Results The mean preoperative physi-ological score (PS) and operative severity score (OS) in the complication group (38 cases) were significantly higher than those in the noncomptication (56 cases) (17.26 ± 2.84 vs 16.04 ± 2.77; 19.50 ± 5. 14 vs 13.00 ±3.81 ) ( P ＜ 0.05) . In the modified POSSUM, the area under ROC curve was 0. 856, the cut point 43%, sen-sitivity 73.68%, specificity 80. 36%, and coincidence degree 77.66%. Conclusions Since the modified POSSUM scoring system has a high capability of predicting postoperative morbidity for fractures of the pelvis and acetabulum, it can be helpful for surgeons to lower operative risks and ensure safety in operation. When the score is higher than the cut point, the risk is too great for an operation. Therefore, the fracture should be treated non-operatively or mini-invasively until the score is lower than the cut point.
