Objective To analyze the effect of modified Tongyou decoction combined with FOLFOX4 chemotherapy on pre-thrombus state and curative effect of patients with advanced prostatic cancer.Methods 142 patients with advanced prostatic cancer were collected,all patients were randomly divided into study group and control group,71 cases in each group.The control group was given FOLFOX4 chemotherapy and the study group was given modified Tongyou decoction on the baseis of the control group.After treatment,the serum levels of homocysteine(Hcy),D-two dimer(D-D),fibrinogen(FIB),the level of hemorrheology,clinical effect,the incidence of venous thrombosis in one years,the six month survival rate,the one year survival rate were detected in all patients.Resutls After treatment,compared with control group,the serum levels of Hcy,D-D,FIB,the whole blood high,middle and low-shear viscosities,plasma viscosity and the incidence of venous thrombosis in one years were higher in the study group and the difference was statistically significant(P<0.05);the erythrocyte deformability index,effective rate and one year survival rate were higher were higher in the study group and the difference was statistically significant(P<0.05).Conclusion The modified Tongyou decoction combined with FOLFOX4 chemotherapy in treatment of patients with advanced prostatic cancer can improve the prethrombotic state,improve the therapeutic effect,reduce the incidence of venous thrombosis and increase the one year survival rate,and have a guiding significance for clinic.

Objective:To investigate the expression of peripheral blood CD54,CD106,CD62p in patients with multi-infarct dementia.Methods:The levels of serum CD54,CD106,CD62P of 82 patients with multi-infarct dementia were measured with ELISA,and were compared with 23 normal controls.Results:The levels of serum CD54,CD106,CD62p in patients with multi-infarct dementia(CD54:469?76.33 ng/ml,CD106:1 103.3?98.96 ng/ml,CD62p:18.22?8.90 ng/ml) were higher than those in normal controls(CD54:196?45.91 ng/ml,CD106:601.0?76.30 ng/ml,CD62p:6.70?3.30 ng/ml). There were significant difference between the two groups.The levels of serum CD54,CD106,CD62p were positively correlated with the degree of dmentia.Conclusion:CD54,CD106,CD62p are closely related to the development of MID and play an important role in pathlogical procedure of cerebral damage after MID.The levels of CD54,CD106,CD62p in patients with MID implies the degree of their neurological function deficit scores and might be an important indicator to observe the changes of disease.

Polypeptide fragment of rabies virus glycoprotein(RVG)has become one of the most popular polypeptides in drug delivery field,because of its advantages of neurotropiam,penetration of blood-brain barrier and biosafety.Polypeptide fragment of RVG can directly deliver proteins and nucleic acids into brain.Additionally,when polypeptide fragment of RVG couples with drug-loading polymers,nanoparticles or liposomes,it can mediate the latters into brain.The application of the RVG polypeptide fragment provides a safe and effective approach for the treatment of brain diseases with biomolecules,such as chemicals,proteins.plasmids,siRNA,miRNA.

Aim To investigate the regulatory effects of baicalin on apoptosis induced by virus H1 N1 in hu-man pulmonary carcinoma cell A549 . Methods The chips were used to screen the RNA samples in virus-in-fected A549 cells. Differentially expressed genes were selected in the pathway of apoptosis. The mRNA ex-pressions of caspase-3 and -8 were verified by Real-Time PCR. Results With the DNA microarray, the functions of differentially expressed genes involved in apoptosis biological pathways were analyzed by Kyoto Encyclopedia of Genes and Genomes ( KEGG ) Path-way databases. caspase-3, -7, -8, -10, TRAIL, MYD88 , IL1 A and IL1 B were up-regulated in virus-in-fected group. Oseltamivir could down-regulate gene ex-pressions of caspase-3 ,-4 and-8 . High-dose of baica-lin could down-regulate gene expressions of caspase-3 ,-4,-6 and -8. Except gene expressions of above, low-dose of baicalin could also down-regulate gene expres-sions of IL1RAP and Cn. Real-Time PCR experiments showed that baicalin could significantly decrease mR-NA expression of caspase-3 , -4 , -6 , -8 , IL1 RAP and Cn ( P < 0. 01 ) , compared with the virus-infected group. The results also figured that the interference ef-ficacy of low-dose baicalin was better than that of high-doses. As expected, real-time PCR data were in good agreement with the microarray assay. Conclusions Baicalin can be detected in their suppression effect of caspase-3,-4,-6, and -8 mRNA expression, so it re-sists against the apoptosis to fight against influenza vi-rus in vitro.

To explore the safety and efficacy of left atrial appendage (LAA) occlusion under the guidance of local anesthesia and modified transseptal puncture technology by coronary sinus assisted positioning in patients with nonvavular atrial fibrillation (NVAF). Methods: A total of 16 NVAF patients received local anesthesia and percutaneous LAmbre or Amplatzer cardiac plug occluder implantation. There were 12 males and the patients mean age was at (71.0±6.0) years with CHA2DS2-VASc score at (4.1±1.5); all patients had walfarin contradiction or with walfarin related side effect. Transseptal puncture was conducted by coronary sinus catheter as the anatomic location marker. Results: All 16 patients finished transseptal puncture and no relevant complication occurred. 15/16 (93.8%) patients had successful LAA occlusion, 1 patient was abandoned because of LAA anatomic structure variation. The mean operative time was (65.0±23.0) min and the mean X-ray exposure time was (12.0±3.0) min. The mean diameter of occluder was (32.5±6.0)mm. Conclusion: LAA occlusion was safe and effective with local anesthesia and modified transseptal puncture technology by coronary sinus assisted positioning in relevant patients.

Objective To investigate the association between functional polymorphism IVS8-poly (T) in cystic fibrosis transmembrane conductance regulator (CFTR) gene and prostate cancer risk.Methods A population-based case-control study was conducted including 230 prostate cancer patients and 230 agematched controls.PCR-STRP was used to analysis the IVS8-poly (T) tract in CFTR gene.Results The prevalences of the low expression allele,the IVS8-5T,in prostate cancer patients and controls were 1.52 ％ (7/460) and 5.22 ％ (24/460),respectively (x2 =12.489,P =0.002).Logistic regression analysis confirmed the 5T/7T genotype was in protective association with prostate cancer risk (OR =0.232,P =0.003,95 ％ CI0.090-0.599).Conclusion The low expression CFTR IVS8-5T allele contributes to a reduced risk of prostate cancer in Chinese Han population,and may be a protective factor against prostate cancer.

Objective To investigate the function and necessity of ICU to supervise and cure the patients after comprehensive correction of facial skeletal contouring. Methods 178 patients were examined carefully and perfectly before operation to obviate taboo. After comprehensive correction of facial skeletal contouring operation, all the patients were transferred into ICU in order to be supervised and cured comprehensively. Results 26 (14. 61 %) patients had hypoxemia ( SPO2 ≤90 %),11(6. 18 %)kaliopenia (K+≤3. 5 mmol/L) and 18 (10. 11 %) hypertension. 21 patients appeared arhythmia. Among these 21 arhythmia patients, 15 (8.43 %) patients had pyknocardia (HR≥100/min), 3 (1. 69 %) atrial premature beat, 1 (0.56 %) fibrillation atrial, 2 (1. 12 %) premature ventricular contraction, 1 (0. 56 %) Ⅱ degree atrioventricular block. 8 patients had respiratory tract obstruction. 2 (1. 12 %) had hemorrhea of mandible and 1 transfused 600 ml blood. 17 (9. 55 %) patients had restlessness. 65 patients had nausea and vomitting. All patients in ICU having postoperative complications had been deal with corresponding management. There were no respiratory failure,hemorrhagic shock, cardiac arrest after operation in 178 patients. Conclusions ICU can offer timely, continuous, and systemic supervision and cure to patients after comprehensive correction of facial skeletal contouring,and reduce the postoperative emergency rate.
