BACKGROUND:Total flavonoids of hippophae have different degrees of regulation effect on the immune system. However, there is no available evidence addressing the effect of total flavonoids of hippophae on vascular dementia inflammatory factor. OBJECTIVE:To observe the effect of total flavonoids of hippophae on serum tumor necrosis factor-αand interleukin-1βlevels in a rat model of vascular dementia, and to discuss its interventional mechanism for vascular dementia. METHODS:A total of 72 Wistar rats were randomly divided into six groups:sham operation, model, control, high-dose, medium-dose, and low-dose of total flavonoids of hippophae groups. Except for the sham operation group, rats in the other five groups were applied to establish vascular dementia models using the improved“vascular occlusion”method. Sham operation group was only subjected to the isolation of bilateral common carotid artery, without ligation. At 1 day after modeling, rats in control group was intragastrical y given Ginkgo biloba extracts 48 mg/kg?d, while rats in total flavonoids of hippophae groups were given 200, 100, 50 mg/kg?d of total flavonoids of hippophae. Model group and sham operation group received equal volume of saline. After 30 days of administration, rats were detected in Morris water maze. Serum tumor necrosis factor-αand interleukin-1βlevels of rats in different groups were detected after intervention. RESULTS AND CONCLUSION:Compared with sham operation group, the vascular dementia model rats had a disordered learning and memory ability, and increased levels of serum tumor necrosis factor-αand interleukin-1β(P<0.05). After intervention of Ginkgo biloba extracts and total flavonoids of hippophae, the learning and memory abilities were improved, and serum tumor necrosis factor-αand interleukin-1βlevels were decreased (P<0.05). Total flavonoids of hippophae can reduce serum tumor necrosis factor-αand interleukin-1βlevels in vascular dementia rats. This may be the main mechanism of treating vascular dementia.

Objective: To investigate the association between body height and risk of cancer incidence among adult men and women in Shanghai. Methods: Baseline information on body height and other factors relevant for cancer was obtained from Women's (1996-2000) and Men's Health Studies (2002-2006) in Shanghai. Participants with missing data on body height, or those lost to follow-up in one year after the study enrollment were excluded, leaving 74 709 women and 61 161 men for analysis. There were 4 031 incident cancers for women and 2 047 for men confirmed at the end of 2009. COX regression model was used to evaluate the HR s ( hazard ratios) and 95% CI (confidence interval) between height and cancers. Results: After adjustment for some potential confounding factors including age, weight, physical activity, energy intake, occupation, income and reproductive factors (for women only), HR s and 95% CI s for cancer incidence per 1 standard deviation (6 cm for both men and women) increment in body height were 1.04 (95% CI : 1.00-1.08) for total cancers, 1.18 (95% CI : 1.05-1.33) for stomach cancer, 1.34 (95% CI : 1.06-1.70) for kidney cancer and 1.05 (95% CI : 0.99-1.12) for breast cancer in women; and 1.06 (95% CI : 1.00-1.11) for total cancers, 1.11 (95% CI : 1.00-1.25) for lung cancer, 1.34 (95% CI : 1.02-1.75) for pancreatic cancer, 1.23 (95% CI : 1.01-1.49) for rectal cancer and 0.78 (95% CI : 0.66-0.94) for prostate cancer in men. Conclusion: A possible link between body height and cancer incidence in men and women is suggested. The association between body height and cancer incidence varies by cancer type.

From October 1969 through December 1981, 3483 esoghageal carcinomas without superficial lymphatic metastasis were treated by 60 Co in our hospital. The radiation dose was over 50Gy and follow-up was over ten years. Results: No significant difference of survival rates was found in various cancer locations in the esophagus combined with the data between our hospital and Xingtai Tumor Hospital, the 5-year survival rates for lower third esophageal cancer were 20.7%～36.4% in surgery group and only 4.3% in radiation group. The 5-year survival rates were also significantly diffrent between radiation group(34.7%) and surgery group (64.9%) for cancer length of

Objective To evaluate the effect of the high concentration of sevoflurane wash-in in induction of anesthesia on the cardiac function in young infants.Methods ASA Ⅰ young infants,aged 28-60 days,undergoing resection of hemangioma on body surface under general anesthesia,were studied.According to the principle of randomized block design,8 blocks were designed based on the body weight (3.0-3.4 kg,3.5-3.9 g,4.0-4.4 kg,4.5-4.9 kg,5.0-5.4 kg,5.5-5.9 kg,6.0-6.4 kg,6.5-6.9 kg),with 3 infants in each block.The infants were randomly divided into 3 groups (n =8 each):anesthesia induction with 6％,7％ and 8％ sevoflurane groups (groups S1-3).In groups S1-3,the infants inhaled 6 ％,7 ％ and 8 ％ sevoflurane respectively for induction of anesthesia.Transthoracic echocardiographic examinations were performed before sevoflurane inhalation (baseline,T1) and at 4 min of sevoflurane inhalation (T2) to record the stroke volume (SV),left ventricle end-diastolic volume (LVEDV),ejection fraction (EF),stroke volume index (SI),heart rate (HR),cardiac output (CO),cardiac index (CI),peak early diastolic velocity of mitral annulus (Ea),peak late diastolic velocity of mitral annulus (Aa),peak systolic velocity of mitral annulus (Sa),and Tei index.The mitral annulus poteroseptal Ea/Aa (Ea/Aa) was calculated.Results Compared with the baseline value,SV,EF,SI,Ea/Aa and Tei index were significandy increased,HR,Sa,Ea and Aa were significantly decreased (P ＜ 0.05),and no significant change was found in LVEDV,CO and CI at 4 min of sevoflurane inhalation in groups S1-3 (P ＞ 0.05).Tei index was significantly higher in groups S2.3 than in group S1 (P ＜ 0.05).There was no significant difference in the parameters of cardiac function between group S2 and group S3 (P ＞ 0.05).Conclusion 6 ％,7 ％ and 8 ％ sevoflurane wash-in in induction of anesthesia exert no effect on the cardiac function in young infants,and the 3 concentrations can be recommended for clinical use.

To study the characteristics of pharmacological effects of property combinations of traditional Chinese medicines (TCMs) distributing in the stomach meridian based on medicinal property combination, in order to further define the association relationship between properties of TCMs and their pharmacological effects, and build a bridge for the interpenetration and combination between the medicinal property theory of TCMs and their pharmacological effects. On the basis of the studies on the medicinal property theory of TCMs distributing along the kidney meridian and their pharmacological effects, efforts were made to collect relevant data for medicinal properties and pharmacological effects and mine the characteristics of pharmacological effects that were corresponding to relevant medicinal property combination by processing materials related to medicinal properties and pharmacological effects with the association rules method. According to the analysis, TCMs distributing along the kidney meridian with different medicinal property combinations were significantly differentiated in the pharmacological effects, but shared identical pharmacological effects, such as immunological enhancement. In this study, TCMs distributing along the kidney meridian with different medicinal property combinations were taken as the carriers to closely integrate the traditional Chinese medicine theory with the modem study achievements, lay a solid foundation for further developing and enriching the traditional Chinese medical property theory, while providing a new perspective on the development of modem medicine.

Objective:To optimize the extraction technology of radix scutellariae. Methods: The extraction of radix scutellariae was scanned by ultraviolet spectrophotometry from 200 to 400nm. The content of baicalin was determined by HPLC. The ultraviolet ab-sorption, baicalin content and extraction rate were used as the indices, and the optimal extraction conditions were investigated by single factor experiments and orthogonal design tests. Results: The optimal extraction conditions were as follows: the ethanol concentration was 60%, the solid-liquid ratio was 1∶40, ultrasound extraction time and temperature was 40 min and 60℃, respectively. Conclusion:The extraction of radix scutellariae has good sunscreen with promising ultraviolet absorption in UVB. Ultrasound extraction has high ex-traction yield with short time, which can be used to extract sun-screening constituents from radix scutellariae.
