ABSTRACT

Objective To investigate the risk factors for the occurrence of cerebral infarction in patients with capsular warning syndrome (CWS). Methods Consecutive patients with transient ischemic attack (TIA) meeting the CWS clinical manifestations were col ected retrospectively. They were divided into either a cerebral infarction group or a non-cerebral infarction group according to the brain diffusion weighted imaging findings. The independent risk factors for patients with CWS were identified through the comparison of demographic and baseline clinical data. Results A total of 39 patients were enrol ed, including 25 males (64. 1%) and 14 females (35. 9%), and their mean age was 58. 9 ± 10. 3 years. There were 21 patients in the cerebral infarction group and 18 in the non-cerebral infarction group. Compared with the non-cerebral infarction group, the age of patients in the cerebral infarction group was older (62. 5 ± 9. 3 years vs. 54. 8 ± 10. 2 years;t=2. 470, P=0. 018). The constituent ratio of the patients with a history of previous stroke or transient ischemic attack was higher (33. 3% vs. 5. 6%; P=0. 049), the fasting blood glucose level was higher (8. 2 ± 3. 2 mmol/L vs. 6. 0 ± 1. 3 mmol/L; t=2. 748, P=0. 009), and ABCD2 score was higher (5. 2 ± 1. 1 vs. 3. 5 ± 1. 1;t=4. 734, P<0. 001). Multivariate logistic regression analysis showed that the ABCD2 score was an independent risk factor for cerebral infarction in patients with CWS (odds ratio, 4. 529, 95% confidence interval 1. 233-16. 627;P=0. 023). Conclusions The higher ABCD2 score was an independent risk factor for the occurrence of cerebral infarction in patients with CWS. It can be used as an evaluation tool for predicting the risk of cerebral infarction in patients with CWS.

ABSTRACT

Objective To evaluate the effect of resveratrol on the growth of an established A431 xenogratt tumor in nude mice.Methods The model of human skin squamous cell carcinoma was established by inoculating A431 cells in log-phase growth into the left axillary fossa of Balb/c (nu/nu) nude mice.After 7-8 days,60 mice bearing human A431 skin squamous cell carcinoma xenografts were randomly and equally divided into 6 groups:blank control group receiving no treatment,negative control group treated with intraperitoneal sodium chloride physiological solution,positive control group treated with intraperitoneal cyclophosphamide,high-,medium-and low-dose resveratrol groups treated with intraperitoneal resveratrol of 40,20 and 10 μg per gram body weight per day,respectively.Tumor size was measured at a 4-day interval during the treatment course.After 14-day treatment,the mice were sacrificed.Xenograft tumors were removed from these mice and subjected to weight measurement,pathological examination by hematoxylin and eosin (HE) staining and apoptosis detection by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL).Western blot was conducted to quantify the protein expression of apoptosis-related factors,including phosphorylated extracellular signal-regulated protein kinase (p-ERK),p53 and caspase 3.Data were processed by SPSS 13.0 software,and statistical analysis was carried out by analysis of variance and Pearson correlation analysis.Results By the end of treatment,the xenograft tumor volume was (1153.56 ± 255.41) mm3,(1001.69 ± 115.08) mm3,(1206.80 ± 175.88) mm3,(1342.28 ± 211.12) mm3,(1642.34 ± 225.85) mm3 and (1564.32 ± 156.49) mm3,and the weight was (1.84 ±0.30) g,(1.72 ± 0.39) g,(1.96 ± 0.40) g,(2.67 ± 0.73) g,(3.16 ± 0.52) g,and (3.33 ± 0.59) g,respectively in the positive control group,high-,medium-and low-dose resveratrol group,negative control group and blank control group.Significant differences were observed in the xenograft tumor volume (F =16.00,P < 0.05) and weight (F =19.15,P < 0.05) among the 6 groups.According to the tumor weight,the growth of tumor was inhibited by 45.57%,37.97% and 15.51% respectively in the high-,medium-and low-dose resveratrol groups.Increased apoptotic index was observed in the positive control group,high-,medium-and low-dose resveratrol groups compared with the negative control group and blank control group (36.79 ± 8.86,33.15 ± 6.00,18.09 ±3.92 and 10.53 ± 4.20 vs.3.87 ± 1.63 and 2.73 ± 1.61,F =93.26,P < 0.05).Analysis of variance showed that the protein expressions of p-ERK,p53 and caspase 3 were all higher in the three resveratrol groups than in the negative control group and blank control group (F =6.65,6.78,11.56,respectively,all P < 0.05).The protein expression of p53 was statistically correlated with p-ERK (r =0.68,P < 0.05) and caspase 3 (r =0.56,P <0.05).Conclusions Resveratrol shows an inhibitory effect on the growth of human A431 skin squamous cell carcinoma xenografts in nude mice,likely by increasing p53 expression and inducing tumor cell apoptosis via the activation of MAPK/ERK pathway.

ABSTRACT

OBJECTIVE: To observe the effect of Wenxin granules on heart function of patients with chronic congestive heart failure (CHF). METHODS: 82 CHF patients were randomly divided into treatment group and control group (n=41). Both groups were given routine treatment(alternative use digitalis,diuretic,vasodilator, ACEI, Beta-blockers according to patient’s condition). Treatment group were additionally administered with Wenxin granules for four weeks. The symptom and improvement of heart function of two groups were compared. RESULTS: The symptom and heart function of patients in both groups were improved remarkably. Treatment group was significantly superior to control group in curative effect (P
