The cancer stem cell hypothesis posits that cancer stem cells,which are rare among the tumor cell population and share many common properties with normal stem cells,and have been positively identified and successfully isolated from some cancers,are responsible for tumorigenesis and implicated in multistage cancer progression,particularly with respect to metastasis.A better understanding may provide insights into the development of cancer stem cell-targeting therapeutic strategies.The examines what is known regarding cancer stem cells' concept,comparison with normal stem cell,potential origins,assays for isolation and their roles in metastasis.

Objective To investigate the correlation between I405 single nucleotide polymorphism in CETP gene and the therapeutic effect of simvastatin in dyslipidemia patients.Methods Genotype information of I405V in CETP gene was detected by SNaPshot TM primer extension assay in 375 dyslipidemia patients.Blood lipid profiles before and 6 weeks after treatment with simvastatin were recorded to analyze the correlation between the therapeutic effect of simvastatin and I405 polymorphism genostype.Results The frequency of I405 V polymorphism was 38.9%in II genotype,48.5% in IV genotype and 12.5%in VV genotype.After being treated with simvastatin for 6 weeks,the serum levels of TC were significantly decreased by 1.21 mmol/L(P <0.01)and HDL-C level was significantly increased by 0.74 mmol/L(P <0.01).Compared with the IV and VV genotypes of I405V polymorphism,the decrease of TC in II genotype patients were 0.26 mmol/L and 0.16 mmol/L more respectively (P<0.01).Meanwhile,the increase of HDL-C was significantly different among three genotypes(P<0.01).HDL-C in II genotype was increased by 0.85 mmol/L,which was 0.19 mmol/L and 0.15 mmol/L more compared with IV genotype and VV genotype,respectively.Conclusion I405V polymorphism in CETP gene is similar with the lipid-regulating effect of simvastatin.The decrease of blood lipid is more significant in patients with II genotype compared with patients with V allele,suggesting that II genotype is the maker which may predict the therapeutic effect of simvastatin in dyslipidemia patients.However,this conclusion still needs further evaluation.

Objective To analyze the effect of health education on recurrence of acute pancreatitis in discharged patients. Methods All patients with acute pancreatitis accepted health education during the first hospitalization.92 patients were randomly allocated to the trial group and the control group.The trial group was kept on being treated with health education for 18 months after discharged form the hospital but the control group didn' t.Results The recurrence rate of trial group was 8.50% but the control group was 24.44%(P

astaxanthin is an effective antioxidant and natural pigment which has wide application. Phaffia rhodozyma is a good source of astaxantin, but wild strain has limited use in industry because of low production level of astaxanthin. Several mutants of Phaffia rhodozyma were obtained by exerting mutagen N-methyl-N-nitro-N -nitrosoguanidine. The growth curve suggested that pigments were mainly produced in the middle and latter periods of log phase. The pigments were extracted from Phaffia rhodozyma and analysed by esterification, thin layer chromatography and absorption spectrometry. It was proved that astaxanthin, astaxanthin diester and ?-carotene were the major components of the pigments produced by Phaffia rhodozyma. We also studied the pigments producing phase of Phaffia rhodozyma. and founded that astaxanthin was stable to light under butylated hydroxytoluene coexistance.

Nowadays, LAN can't meet the requirements of field communication, and WLAN is playing more and more important role for its strong transmission ability and high mobility. This paper introduces the application of WLAN to filed medicine.

Objective: To explore the effect of Fuzheng granules on immune function activities in animal models.Methods: The effects of Fuzheng granules were investigated in normal mice and immunosuppressive mice by macrophage englobement rate and index of phagocytosis,leucocyte quantity,lymphocyte conversion ratio induced by adhesin,serum hemolysin,content of serum con-complement.Results: Fuzheng granules could significantly elevate the macrophage englobement rate,index of phagocytosis,leucocyte quantity,lymphocyte conversion ratio induced by adhesin,serum hemolysin,content of serum con-complement in above mice.Conclusion: Fuzheng granules had the effect of improving immune function activities.

Using sustained release tablets of gardenia extract as model drug and DPPH radical scavenging capacity as antioxidant index, the feasibility of using pharmacodynamics index was explored to evaluate sustained release tablets. Applying the established quantifiable method of DPPH radical scavenging to the dissolved liquid of model drug, release profiles and biological effects profiles were drawn, and their correlation was discussed. A good correlation was observed by linear regression and f2 actor, suggesting that the indicator could be used to evaluate sustained release tabletsofextracts of gardenia in which iridoids were mainly involved.

The effects of Wumeiwan (WMW) on TNF-alpha, IL-6, IL-8, IL-10 and NF-kappaBp65 in rats with ulcerative colitis (UC) were investigated, the curative effectiveness of WMW vs salicylazosulfapyridine (SASP) was compared, and the action mechanism was analyzed. Fifty-Six Sprague-Dawley (SD) rats were randomly divided into four groups (n=14 in each group, with equal ratio of male and female): normal control group, model group, SASP group, and WMW group. Except normal control group, the rat UC models in the remaining three groups were established using the method of 2.4-dinitrochlorobenzene (DNCB) immunization and acetic acid local enema. The rats in model group, SASP group, and WMW group were treated with distilled water, SASP, and WMW respectively. The changes in the symptoms and signs were observed, and levels of IL-6, IL-8, TNF-alpha, IL-10 and the expression of NF-kappaBp65 in the colonic tissues were statistically analyzed. The results showed that the levels of IL-6, IL-8, and TNF-alpha were significantly increased (P<0.01), while those of IL-10 significantly reduced (P<0.01) after establishment of rat UC models as compared with normal control group. The levels of IL-6, IL-8, and TNF-alpha were obviously lower, but the level of IL-10 was obviously higher in WMW and SASP groups than those in model group (P<0.05). The levels of IL-6, IL-8, and TNF-alpha were lower, while the level of IL-10 was higher in WMW group than in SASP group. NF-kappaBp65 was expressed negatively or weakly in normal colonic tissues. The positive expression rate of NF-kappaBp65 in WMW group and SASP group was obviously lower than in model group (P<0.01), and there was significant difference between WMW group and SASP group (P<0.05). It was concluded that rat UC model was established successfully. WMW could up-regulate the expression of IL-10, down-regulate the expression of TNF-alpha, IL-6, IL-8, and inhibit the NF-kappaBp65 activity to adjust immune function, indicating WMW had better curative effects on UC in rats.

The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.
