Protective effects of Ginkgo biloba extract (GBE) on ischemia in rat and mice brain were studided. The ischemia model in brains was prepared by occlusion of bilateral carotid arteries and vertebra arteries in rat. The results demonstrated that GBE had no effect on electroencephalogram (EEG) of 5 min of ischemia, but it promoted the recovery of EEG during reperfusion. When it was reperfushed for 10 min,amplitude of EEG in the control group only recovered from 17. 2% after ischemia to 46. 6% of normal level. While 0. 2g/kg GBE has a recovery of 93% from normal level. At 4. 0g/kg GBE the life-span of mice with bilateral ligated carotid arteries was significantly lengthened. The above results proved that GBE has some protective effect on anoxia caused by acute ischemia in rat and mouse brain.

Objective To investigate the clinical value of thinprep cytology test(TCT) combined with colposcopy in diagnosis of cervical lesion. Methods Retrospective analysis was conducted in 174 females with abnormal cervical smear. All the patients underwent colposcopy to screen the cervical lesions. According to the pathological results,the clinical value of TCT and colposcopy was analyzed and compared. Results In the 174 cases with abnormal cervical smear,the positive rate of atypical squamous cells(ASC) was 27. 0% (47/174). There were 92 low grade squamous intraepithelial lesion (LSIL) (52. 9%) ,33 high grade squamous intraepithelial lesion (HSIL) (19. 0%) and 2 squamous cell cancinoma (SCC) (1. 1%) . According to the diagnosis by biopsy and pathology,the positive rate of benign cervical cell(BCC) was 16. 1% (28/174) .cervical intraepithelial neoplnsia (CIN) I 42. 0% (73/174), CIN II 18.4% (32/174), CIN ffl 21. 8% (38/174) and SCC 1. 7% (3/174) . The coincidence rate of TCT and pathology was 83. 9% (146/174). Conclusions TCT and colposcopy are a practical approach for detecting cervical lesion. TCT combined with colposcopy is the optimal screening approach for cervical lesion, which can enhance the sensitivity and specificity of the diagnosis of cervical lesions.

Objective To analyze the correlation of traditional Chinese medical constitution types withcardiovascular risk factors in community hypertension patients. Methods We defined the constitution types of 1108 community hypertension patients, created personal health archives and provided routine examination for the subjects. After that, we input and analyzed the relevant data and results by computer. Results In 1108 cases of hypertension patients, 229 (20.67%) were defined as harmony physique, 879 (79.33%) as biased physique. In patients with biased physique, phlegm-dampness physique accounted for 25.54% (283 cases) , and then came yin deficiency physique and Qi deficiency physique, which accounted for 15.16% (168 cases) and 13.18% (146 cases) , respectively. The biased physique was dominated by single biased physique with a total of 590 cases ( 67.12%) , but the complex physique was also in large quantity, with a total of 289 cases ( 32.88%) . The complex physique consisting of two kinds of single physique was commonly seen in the patients with complex physique, accounting for 15.70%. The complex physique consisting of more kinds of single physique had less percentage. Phlegm-dampness physique was a kind of physique involving the most cardiovascular risk factors. Patients with phlegm-dampness physique had higher incidence of overweight, abnormal lipid level, family history of cardiovascular disease, lack of physical exercise and electrocardiographic abnormality, and the difference was statistically significant compared with other physique types ( P<0.05 or P<0.01) . Conclusion Phlegm-dampness, yin deficiency and Qi deficiency physique are the three commonly-seen constitution types in hypertension patients. Phlegm-dampness physique is the most commonly-seen biased physique and is also a kind of physique involving the most cardiovascular risk factors. Prevention and management in consideration with the constitution characteristics and cardiovascular risk factors will be a new prospective method for the treatment of hypertension patients in community.
