Objective:To research and summarize the characteristics and medication regulars of external medicine for hydrocephalus therapy with TCM. Methods:Retrieved literatures of explicitly recorded external medicine in all ages,input its drugs into the Excel sheet specifing and specified various terms used for drug,adopted spss17.0 frequency analysis,principal factor analysis,cluster analysis, and sought its regulars.Results:Frequency analysis of external medicine from higher to lower in order as Radix Ledebouriellas,Rhizoma Bletillae,Arborvitae seed,Cinnamon bark,Ackinthepulpit tuber,Rhizoma Zingiberis ect. Withdrawed 16 main factors from 50 original targets, used cluster analysis made 16 main factors into 10 types as eliminating phlegm for resuscitation,activating blood and disinhibiting fluid etc. Conclusion: External medicine for hydrocephalus therapy mainly as drugs for activating blood and dissolving stasis, expelling wind with diaphoresis, warming yang,reinforcing kidneys to strengthening bones,regulating qi.Multivariate statistical analysis can objectively and comprehensively reflect the characteristics and regulars of external medicine and provided some exploratory thoughts.

OBJECTIVETo investigate the effect of the anticoagulants on PRP quality, so as to clarify the appropriate anticoagulant used in PRP production.
METHODSThe microstructure change of platelets collected via heparin, citrate, acid citrate dextrose (ACD) and citrate-theophylline-adenosine-dipyridamole ( CTAD) was observed by TEM following time course. The extent of spontaneous activation of platelets in four groups was detected by measuring sP-selectin in plasma. The TGF-β1 release amount of activated PRP of four groups was measured.
RESULTSCTAD is superior to other anticoagulants in maintaining the integrity of platelet structures for a long time and preventing platelet spontaneous activation. ACD slightly surpassed heparin and citrate in above two aspects. ACD-PRP and CTAD-PRP released significantly more TGF-β1 compared with heparin and citrate.
CONCLUSIONSThe PRP quality and biological effects were strongly associated with the type of Anticoagulants. ACD and CTAD are optimal anticoagulants in PRP production for they can maintain platelet viability at a high level.

Objective:This study was designed to explore the effects and mechanisms of raltitrexed on the growth of the human gastric cancer cell line (MGC-803) transplanted in nude mice. Methods: Models of MGC-803 xenograft transplanted in nude mice were established. Body weight, mental state, food, and stool of the nude mice were closely monitored, and the inhibitory action in the tu-mors was evaluated after drug intervention. Distribution and apoptosis of the tumor cells were examined through flow cytometric assay. P53 mRNA and protein expression levels were determined through reverse transcription-polymerase chain reaction and Western blot analysis. Changes among the three groups were compared. Results:Body weights and tumor volumes of the nude mice were lower in the raltitrexed and 5-fluorouracil (5-Fu) groups than those in the control group. Tumor inhibition ratios were 49.02%and 45.75%in the raltitrexed and 5-Fu groups, respectively. In the G0/G1 stage, the number of cells decreased in the raltitrexed and 5-Fu groups. Signifi-cant differences were found between the experimental and control groups (P<0.01). In the S stage, the number of cells increased in the raltitrexed and 5-Fu groups, with significant differences from the control group (P<0.01). P53 mRNA and protein expression levels in the raltitrexed and 5-Fu groups were significantly higher than those in the control group (P<0.01), but no significant differences were found between the raltitrexed and 5-Fu groups (P>0.05). Conclusion:Raltitrexed can inhibit the growth of MGC-803 xenograft trans-planted in nude mice and shows inhibitory effect similar to that of 5-Fu. Raltitrexed can induce the S-phase block of the cell cycle and cell apoptosis in the MGC-803 xenografts in the nude mice. This drug may exhibit an antitumor effect by upregulating the p53 mRNA and protein expression levels.

ObjectiveTo investigate the protective effect of erythropoietin (EPO) on human renal tubular epithelial-mesenchymal transition (EMT) induced by high glucose. MethodsCultured HK-2 cells were divided into 5 groups: normal control group, osmolarity control group, high glucose group, high glucose with EPO (5 U/ml)group and high glucose with EPO (10 U/ml)group. The mRNA expression of α-SMA, TGF-β1, Smad2, ILK of cells were measured by RT-PCR. The levels of intracellular α-SMA and TGF-β1 protein were measured by immunocytochemistry. ResultsCompared with the control groups, mRNA expression of α-SMA, TGF-β1, Smad2, ILK and protein expression of α-SMA and TGF-β1 were increased after high glucose treatment (P<0.01). Compared with the high glucose group, EPO 5 U/ml or EPO 10 U/ml remarkably down-regulated the expression of α-SMA, TGF-β1, Smad2 and ILK (P<0.01). ConclusionEPO can inhibit the progression of EMT and the up-regulation of TGF-β1, Smad2 and ILK induced by high glucose.

Objective To identity the characteristic metabolites of platelets activation by Plasma metabolic Profiling in acute myocardium infarction ( AMI ) patients.Methods From August 2012 to February 2013, samples in three groups were collected at Tianjin Third Central hospital, including AMI group (25 clinically diagnosis myocardial infarction, 14 male, 11 female, average age 67 ±13 ) , control group(A) and simulation platelet activation group(B) (A and B group composed of 29 health volunteers, 11 male 18 female, average age 65 ±12 ) .After collagen platelet activation on B group, HPLC-LTQ Orbitrap XL MS platform was used to analyze the serum metabolic profiling in three groups respectively.Principal component analysis ( PCA) model and partial least squares-discriiminate analysis ( OPLS-DA) model were established to select characteristic metabolites in A and B group, and then tested in X group to find common ions.Results 20 characteristic metabolites were selected in A and B group.3 different lysophosphatidyl choline, sphingosine 1-phosphate, ethanol amine amides, sphingosine choline phosphate, thromboxane, 14-methyl hexadecanoic acid showed the same changing trend and were significant different between B group and AMI group.Conclusions Characteristic ions selected by metabolic profiling technology had significant distinguishing ability for AMI patients and health control.They may provide early diagnosis for AMI.

Background Although great advances have been made in prevention and treatment of CVD through drug therapies and other procedures,diet and lifestyle modification remain the foundamental aspects in clinical inter vention for prevention and treatment of hypertension.Objective The purpose of this research is to investigate the impact of variour dietary patterns on traditional cardiovascular risk factors in essential hypertensives in Beijing area. Food frequency questionnaire (FFQ) survey was carried out in a cohort of 424 patients of hypertension.Methods All participants completed an FFQ.Baseline clinical data (height,weight,waist circumference and biochemical da- ta) were collected by physical examination and biochemical assay.According to their dietary patterns,three dietary pattern were delineated:vegetarian diet(n=95),meat dominant diet(n=133) and balanced diet(n=196).Clinical and biochemical data were compared between them,and analyzed by multivariate logistic regression models.Results 1)The morbidity of obesity in meat dominant people was significant higher than vegetarians (46.6% vs 21.7%,P
