The effect of traditional therapy is limited for liver cancer,gene therapy gets more and more recognition in recent years.Oncolysis virus is a kind of conditionally replicating virus,with special reproductivity in cancer cells,and then kills them.Gene agents are usually introduced into tumor tissue by intra-tumor and intra-arterial injection,and the technique of interventional therapy is able to satisfy the demand excellently.So,some breakthrough is expected in treating liver cancer by skillfully combining oncolysis virus and interventional technique

Twenty-nine thyroid tissue samples were collected from patients with thyroid nodules.The total RNA were extracted,the gene expressions of TFF3,HMGA2,C1orf24,and DDIT3 were detected by RT-PCR.In comparison with normal thyroid tissues,the expression of C1orf24 mRNA was decreased in the follicular thyroid adenoma (FTA) group,but increased in the follicular thyroid carcinomas (FTC) group.The expressions of DDIT3 and HMGA2 mRNA were increased in both FTA and FTC groups,and were even higher in the latter.The expressions of TFF3 mRNA level were decreased in FTA and FTC.The data suggested that molecular markers C1ort24,DDIT3,HMGA2,and TFF3 in thyroid tissue seem to be helpful in the differential diagnosis between follicular adenomas and carcinomas.

To investigate the expression of inducible nitric oxide synthase (iNOS) in the hydropic cochlea of guinea pigs, the experiment consisted of two groups: normal control group and experimental group. The hydropic animal model was established by destroying the endolymphatic sac. The expression of iNOS in the hydropic cochlea was examined by immunohistochemistry. The results showed that the expression of iNOS in the hydropic cochlea was positive. The expression of iNOS in the area of stria vascularis and spiral ganglion cells was much stronger. It is suggested that nitric oxide is involved in the pathophysiology of cochlear dysfunction in hydropic cochlea.

The object of this study was to investigate the anti-ototoxic effect of iminoethyl-lysine on cochlea of guinea pig damaged by gen-tamicin. The experiment consisted of three groups: normal control group, experimental treatment control group and experimental treatment group. Guinea pigs of the latter two groups were subjected to hypodermic injection of gentamicin, at the same time guinea pigs of the experimental treatment group were treated with intraperitoneal injection of iminoethyl-lysine. while guinea pigs of the experimental control group were treated with the same volume of saline. Guinea pigs of the normal control group were treated with hypodermic and intraperitoneal injection of the same volume of saline as that of the other two groups. The expression of iNOS was examined in the cochleas of all groups by immunohisto-chemistry. ABR hearing threshold shift were examined, and the damage of hair cells of cochleas of all groups was investigated by scanning electronic microscopy. The results showed that iNOS expression was negative in cochleas of the normal control group, and positive in that of other two groups. The expression of iNOS in the experimental control group was much more stronger than that of the experimental treatment group. The ABR threshold shift of the experimental treatment group was much more lower than that of the experimental control group. The damage of cochlea of the experimental control group was much more severe than that of the experimental treatment group. These results suggest that the expression of iNOS is positive in gentamicin-damaged cochleas. Iminoethyl-lysine has significant anti-ototoxic effect on the cochlea damaged by gentamicin, suggesting nitric oxide plays a very important part in the process of the cochlea injury by gentamicin.

Tibetan medicineLiu-Wei Mu-Xiang(LWMX) pill, a traditional compound medicine, has special therapeutic effects in the treatment of gastrointestinal anabrosis, especially chronic gastric ulcer. It has been widely applied in the clinics in Tibetan region. Nevertheless, the current standards for quality control are insufficient and incomplete, which makes it difficult to ensure its quality. This review focused on two closely related perspectives, which were the effective material basis and quality control, to summarize and review the recent advancement in relevant studies. This review also pointed out that the burning questions for Tibetan medicine standards were the origin confusion and“different medicines with the same name”. It offered meaningful suggestions for the consideration to improve its quality standards.

Objective To study the effect of Yuan‐source Points and Collateral‐points combination and Bushen Yishou cap‐sule on hemorheology and hs‐CRP in patients with cerebral infarction .Methods A total of 120 patients with neurological function defects diagnosed with cerebral brain infarction were randomly divided into 3 groups ,who were given general treatment and nursing as usual ,Acupuncture group in general treatment based on Yuan‐source Points and Collateral‐points combination for enjoy points principles ,to acupuncture treatment ;drug group to oral Bushen Yishou capsule;combined group to Yuan‐source Points and Collat‐eral‐points combination and oral Bushen Yishou Capsule .Neurological function defects scores ,blood rheological properties and blood hs‐CRP were evaluated in all patients before and after treatment for 1 month .Results Three sets of results in treatment of limb function after scoring ,hemorheology and serum hs‐CRP levels were significantly improved (P<0 .01) .There was better improve‐ment in Combined group than these in Acupuncture group and Drug group respectively (P<0 .01) .Conclusion Yuan‐source Points and Collateral‐points combination combined with Bushen Yishou capsule can significantly improve neurological function and hemo‐rheology ,hs‐CRP levels in patients with cerebral infarction .

Objective To study the influence of cholangiocarcinoma cells on endothelial cells in a co-culture system. Methods A co-culture system of eholangioeareinoma cell line QBC939> and endothelial cells was established in vitro (co-culture group). Endothelial cells were cultured individually during the same time (control group). The mixed supematant of cholangiecareinoma cells and endothelial cells was in the mixed group. Light microscopy and transmission electron micrescopy were used to observe the morphology of the endothelial cells. Changes in expression of ppI25FAK, MMP-2, MMP-9 and uPA of the endothelial cells were detected by mmunofluorescence, and the activities of MMP-2 and MMP-9 were detected by gelatin zymography. All the data were analyzed by paired t test. Results The intercellular space between endothelial cells in co-cuhure group was wider than in the control group. The expression of pp125FAK, MMP-2, MMP-9 and uPA was 394 ±51,455±82, 377±48,422±55 in control group, and was 1096±128,931±72,815±76,801±56 in the eo-euhure group. The difference between the 2 groups had statistical significance (t = 6.53,4.32, 3.61,3.45, P < 0. 05). The values of gray-scale scanning of MMP-2 and MMP-9 in the mixed group were 240.2±15.2 and 2.4±0.8, respectively. The values of gray-scale scanning of MMP-2 and MMP-9 in the co-culture group were significantly increased, they were 687.4 ± 43.6 and 150.9 ± 13.2, respectively (t = 4.89, 5.43, P < 0.05). Conclusions The intercellular space between endothelial ceils and the expression of the proteolytie enzymes are increased after co-culturing endothelial cells with eholangiocarcinoma cells. Proteolytie enzymes may be involved in the process of degradation of subendothelial matrix, and promotes the metastasis of cholangiocarcinoma.
