Objective To evaluate the efficiency of primary hepatic carcinoma(PHC)using tran- scatheter arterial chemoembolization(TALE)combining with MSC.Methods Treatment group(30 patients with unresectable PHC)adopt MSC after TALE,while control group(10 patients with unresectable PHC)only adopt TALE,then observing the curative effect and survival rate.Results One year after treating,the local effect was 90 %,60 %,1～2 year survival rate was 90 %,30 % respectively,median life span was 15 months. Conclusion To treat PHC with TALE combining with MSC is an effective and non-invasive method.

Objective To investigate the role of directly constitutive activation of p38 mitogen-activated protein kinases(p38MAPKs)signaling in ?-globin gene expression and fetal hemoglobin(HbF)induction,and provide direct data for the relationship between phosphorylation of p38 and erythroid differentiation of human K562 erythroleukemia cells.Methods The human K562 erythroleukemia cells were transfected with pCDNA 3.1-MKK3(Glu)and pCDNA 3.1-MKK3(Ala)recombinant plasmids by lipofectamineTM 2000.Then,the stable cell lines overexpressing constitutively active p38 and constitutively inhibitive p38 activation were established by the addition of G418 to select single cell G418-resistant clones and identification with reverse transcriptase-polymerase chain reaction(RT-RCR)and Western blot assays,named K562-MKK3(Glu)and K562-MKK3(Ala)cells,respectively.Furthermore,the direct effects of constitutively active p38 on the ?-globin gene expression and HbF induction were analyzed by RT-PCR and benzidine staining,respectively.Results The results of RT-PCR and Western blot showed that there were no evident changes in the mRNA and protein levels of p38 for various cell models,but compared with K562,K562-vect,and K562-MKK3(Ala)cells,the phosphorylation of p38 and expression of ?-globin levels in K562-MKK3(Glu)cells were significantly up-regulated.The results of benzidine staining displayed that the mean percentages of positive cells stained by benzidine in K562,K562-vect,K562-MKK3(Ala),K562-MKK3(Glu)cells,and K562-MKK3(Glu)cells treated with SB203580 were(3.2?1.4)%,(3.7?1.2)%,(2.8?0.9)%,(32.6?5.3)%,and(7.8? 2.3)%(q = 7.56 P

A double targets of high throughput screening model for xanthine oxidase inhibitors and superoxide anion scavengers was established. In the reaction system of xanthine oxidase, WST-1 works as the probe for the ultra oxygen anion generation, and product uric acid works as xanthine oxidase activity indicator. By using SpectraMax M5 continuous spectrum enzyme sign reflectoscope reflector, the changes of these indicators' concentration were observed and the influence factors of this reaction system to establish the high throughput screening model were studied. And the model is confirmed by positive drugs. In the reaction system, the final volume of reaction system is 50 μL and the concentrations of xanthine oxidase is 4 mU x mL(-1), xanthine 250 μmol x L(-1) and WST-1 100 μmol x L(-1), separately. The Z'-factor of model for xanthine oxidase inhibitors is 0.537 4, S/N is 47.519 9; the Z'-factor of model for superoxide anion scavengers is 0.507 4, S/N is 5.388 9. This model for xanthine oxidase inhibitors and superoxide anion scavengers has more common characteristics of the good stability, the fewer reagent types and quantity, the good repeatability, and so on. And it can be widely applied in high-throughput screening research.

AIM:To compare the efficiency of fibrin glue to suture technique in pterygium surgery performed with limbal autograft under different methods of anesthesia.
METHODS: A prospective randomised clinical trial was carried out in 60 eyes of 55 patients operated for primary nasal pterygium, which were divided into two groups randomly: experimental group ( 30 eyes in 27 patients ) was under surface anesthesia ( oxybuprocaine ) and control group ( 30 eyes in 28 patients ) was under local anesthesia ( 20g/L lidocaine ). Autologous limbal graft taken from the superotemporal limbus was used to cover the sclera by a fibrin tissue adhesive after pterygium excision. Patients were followed up at least for 6mo. Time of operation, matching degree of graft and VAS score were mainly observed and recorded.
RESULTS: In experimental group the average surgery time was shorter (P=0. 008) and matching degree of graft ( 93%) was better than control group ( 83%) , the differences had statistical significance(P<0.05).
CONCLUSION: The surface anesthesia is enough when using fibrin glue for graft fixation in pterygium surgery, which will shorten surgery time and get better matching degree of graft.

Objective Platelet activating factor(PAF),which has been implicated in the pathophysiology of inflammation in asthma,is degraded and inactivated by PAF acetlhydrolase(PAF AH).To investigate the association of PAF AH activity with genotype in asthmatic children.Methods We studied 57 asthmatic children and 30 normal controls. The plasma PAF AH genotype was detected as representative case with 3 different genotypes (Val/Val,Val/Phe and Phe/Phe) by allele specific polymerase chain reaction(AS PCR).The PAF AH activity in plasam was examined by the changes of substrate assay.Results In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group,and plasma PAF AH activition was absent 15.4 %.In another three groups plasma PAF AH activation were absent 2 %-3 %.There was significant difference of plasma PAF AH activity among 3 groups of genotype(Val/Val,Val/Phe and Phe/Phe).In the similar genotype, there was no significant difference of plasma PAF AH activity between the groups of control and asthma.Conclusions There was imbalace of PAF/PAF AH in asthmatic children. In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group. PAF AH(Val279Phe) gene mutation was related with plasma PAF AH activity.

In the 1960s, modern science began involving the essence of heat syndrome, but there have still no in-depth systematic studies on pathological mechanisms of heat syndrome and action mechanisms of cold and cool herbs. In this study, the animal model with heat syndrome was set up by feeding herbs with hot property, and then cold and cool herbs was applied in the experimental therapy. The two-dimensional electrophoresis and mass spectrometry technologies were adopted to compare the liver mitochondria proteome of the rats of the heat syndrome model and the ones treated with cold and cool herbs, so as to discover specificity-related proteins after heat syndrome and treatment with cold and cool herbs.
