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.

Spearman correlation analysis indicated that plasma Fg and DD levels were significant positively correlated with CAS severity (r=0.426 ,0.535 ,P<0.01 both) ,ATIII level was significant inversely correlated with CAS severity in AMI patients ,(r= -0.438 ,P=0.005) .Multi-factor Logistic regression analysis indicated that plasma Fg and DD levels were independent risk factors for MI (OR=2.836 ,2.231 , P<0.01 both) ,and plasma ATIII level was independent protective factor for MI (OR=0.899 , P=0.014 ) .Conclusion:Plasma Fg and DD levels are independent risk factors for MI and plasma ATIII level is independent protective factor for MI .

Objective The anti-UV-B radiation mechanism of UV-B tolerance strain KFS-9 was studied from the profile of metabolites.Methods The compounds were separated by column chromatography and their structures were elucidated based on GC-MS,LC-TOF-MS,EI-MS and NMR analyses.Results Three unsaturated fatty acids(identified as 9-hexadecenoic acid,9,12-octadecadienoic acid and 11-octadecenoic acid) and 1,2-benzenedicarboxylic acid able to absorb ultraviolet were isolated from the petroleum ether extract of the fermentation liquid of Pantoea agglomerans KFS-9.Fraction(Ⅱ) was isolated from the ethyl acetate extract and was composed of 2,3-butanediol and a series of high unsaturated aroma compounds.Fraction(Ⅱ) had a wide absorption peak,and it could protect E.coli from UV-B damage in some sense.Conclusion Strain KFS-9 produced metabolites that were able to absorb UV to build a natural barrier and so improved the tolerance to UV radiation.The UV-B radiation protection test to the E.coli also showed fraction(Ⅱ) was not the only protector,and there definitely existedother materials and mechanism to protect the strain.

Shanghai district and county health system performance evaluation conceptual frameworkwas proposed based on health services system performance assessment frameworks raised by some countries and international organizations,and combined with Shanghai district and county health system characteristics.This framework contains two first grade indices and seven second grade indices:In the long term goals,'health','satisfaction' and 'disease risk protection' are the county's longterm effects of health system performance assessment dimensions; in the medium-term goals,the'accessibility','cost',' efficiency' and 'quality' are the county' s medium-term effects of health system performance assessment dimensions.This study aimed to evaluate Shanghai county health system's overall performance.Further study is needed in constructing its third grade indices.

Objective To evaluate pericardial devascularization with splenectomy (PCDV) for the treatment of cirrhotic portal hypertension. Methods From January 1994 to December 2004, 177 patients were treated by PCDS, among them posthepatitic cirrhosis was identified in 170 cases, and alcoholic cirrhosis in 7. One hundred and thirty two patients were operated on electively, 25 prophylactically, and 20 emergently. Results The bleeding control rate was 95% , the overall operative mortality rate was 4. 5%. The main causes of death were upper gastrointestinal bleeding, hepatic failure and intra-abdomimal hemorrhage. The mean follow-up time was 3. 6 years. The 5-year survival rate was 90%. The 5-year recurrent bleeding rate was 5. 1% , The rate of postoperative hepatic encephalopathy was 5. 1%. Conclusions This procedure has the advantage of high successful rate of bleeding control, low complication rate, and long term survival.

Objective To compare the appfication of rapid sequence induce nasotracheal intobation with awake nasotracheal intubation with fiberoptic bronchoscope (FOB) in patients with cervical vertebra injury.Methods Forty patients with cervical vertebra injury were randomly divided into group (rapid sequence induce nasotracheal intubation with FOB) and group II (awake nasotracheal intubation with FOB),20 patients in each group.Bp,HR,SpO2 before and during intubation,intubafion time and cases of re-intubation were observed.Results SpO2 maintained normal during intubation.Between group I and group II,there was no significance in intubation lime [(3.12±0.52)min and (3.34±0.65)mini and cases of re-intubafion (2 cases and 1 case) (P ＞ 0.05 ).During intubation,MAP and HR inceased significantly in group II than those in group I (P ＜ 0.05 ).Conclusion The application of rapid sequence induce nasotracheal intubation with FOB is better than awake nasotracheal intubation with FOB in patients with cervical vertebra injury,it is safe and valid.

Matrix metalloproteinase-2 (MMP-2) level and the ERK1/2 signal pathway are dependent factors for the growth and metastasis of cancer. However, the impact of MMP-2 in combination with ERK1/2 in tumor patients with drug resistance is unknown. To determine the relationship between MMP-2 and the ERK1/2 signal pathway, we established an adriamycin (ADM)-induced MG-63 (ADM-MG-63) cell line. With the increase of the ERK1/2 pathway blocker PD98059, we detected the expression levels of MMP-2 and p-ERK1/2 by Western blot in ADM-MG-63 cells. In ADM-MG-63 cells transfected with MMP-2-siRNA, the expression of ERK1/2 was detected for understanding the function of the ERK1/2 signal pathway. Three siRNAs for MMP-2 (MMP-2-siRNA) were designed, and the optimal one was selected and tested at different time points of 24, 48 and 72 h. Under an ADM-induced condition, ADM-MG-63 cells were finally stable living in the medium of ADM (200 ng/mL). PD98059 could effectively suppress the expression levels of p-ERK1/2 and MMP-2. When the MMP-2 was silenced by using MMP-2-siRNA, the expression of p-ERK1/2 was enhanced. It is concluded that MMP-2 may be involved in ADM resistance dependent on ERK1/2 signal pathway, suggesting interference in ERK1/2 may be a new method of targeted therapy for tumor resistance.
