Hepatocellular carcinoma(HCC)has high incidence rate,recurrence rate after surgecal treat-ment,as well as fatality rate in China .HCC is not sensitive to radiotherapy or chemotherapy and no effective treat-ment is available for HCC patients at advanced stage .Sorafenib is the first effective molecularly targeted drug for the treatment of HCC,which represents a milestone in the treatment of HCC .However,it also shows drug resist-ance during clinical application .Therefore,it is important to investigate the mechanism of drug resistance and its molecular markers for HCC .In this review ,we summarize the current status of the studies in these fields .

BACKGROUND: Although the clinical effect of cervical disk replacement in short term has been ascertained, but the middle and long term result is not known, especially for the adjacent level. OBJECTIVE: To observe clinical result and effect of cervical disk replacement on adjacent level in middle and long term. DESIGN, TIME AND SETTING: Retrospective case analysis was performed at Beijing Jishuitan Hospital from December 2003 to March 2005. PARTICIPANTS: Thirty-three patients (aged 35-73 years) undergoing cervical disc replacement were followed up for 3 years. Of them, 25 patients received one-level disk replacement, and 8 received two-level disk replacement. METHODS: The clinical results and imaging before and after operation were compared. MAIN OUTCOME MEASURES: Clinical indexes including JOA grade, Odom’s grade, NDI, SF-36; X-ray: Kellgren X-ray grade, disk cervical height, disk motion, Pfirrmann disk grade, sigittal diameter of spinal cord, and compression of the spinal cord. RESULTS: The point of JOA is 13.62?2.31 before operation, 15.75?1.55 after operation; the differences were significant (P=0.000). For Kellgren X-ray, 10 levels occurred degeneration above the disk replacement level, accounted for 33% (P=0.004), and 9 levels developed degeneration below the disk replacement level, accounted for 32% (P=0.011). No obvious changes in imaging indexes were observed before and after surgery. CONCLUSION: The clinical outcome of cervical disk replacement is good in middle-term follow up. Some adjacent level degeneration may occur after cervical disk replacement, and the degeneration type is osteophyte formation in the adjacent level. This kind of adjacent level degeneration does not affect the clinical outcome in middle term follow-up.

This paper reported a new method of Armillaria mellea isolation-Gastrodia elata tissue isolating. Compared with normal isolating method-rhizomorph isolating method, it showed that the success rate of new method (78% ) was higher than the rhizomorph isolating method (16% ) , besides this, the new method was easier, and growth characteristic of obtained strain was superior to that obtained from rhizomorph isolating method.

ObjectiveTo evaluate the expression of interleukin-1 β ( IL-1β) ; interlenkin-8 ( IL-8 ) ; tumor necrosis factor-α,(TNF-α) in induced sputum in different stages of stable chronic obstructive pulmonary disease (COPD) and heath smoking controls.Methods90 healthy smoking controls and 100 stable COPD patients were enrolled.The levels of IL-1β,IL-8 and TNF-α in induced sputum were detected by radioimmunoassay.ResultsThe levels of IL-1β,IL-8 and TNF-α in stable COPD patients were much higher than those in healthy smoking controls (P =0.000).There are an inverse correlation between FEV1 and levels of IL-1 β,IL-8 and TNF-α in induced sputum (r=-0.678,-0.752,-0.615,all P＜0.05).ConclusionIL-1β,IL-8 and TNF-α may play important roles in the mechanism of airway inflammation in stable COPD.The levels of IL-1 β,IL-8 and TNF-α in induced sputum may be a marke of severity of airway inflammation in stable COPD.

Objective Soft and hard channel minimally invasive interventions for patients with hypertensive intracerebral hemorrhage have been used for many years. A retrospective study was performed to evaluate the superiority of these two methods. Methods 122 patients with hypertensive intracerebral hemorrhage were included in this retrospective study, 64 cases in soft channel group and 58 cases in hard channel group. The clinical effects were compared; catheter retention time and complications of the minimally invasive surgery were also observed in these two groups. Results In soft channel group, NIHSS before the treatment was 18.05±7.77, and NIHSS after the treatment was 7.57±4.68. The mortality was 17.19%. The catheter retention time in hematoma puncture was (4.35±1.56)days, and the catheter retention time in ventricle puncture was (7.67±2.37)days. There were 4 cases of rebleeding and 3 cases of intracranial infection. In hard channel group, NIHSS before the treatment was 18.38±9.02, and NIHSS after the treatment was 8.02±4.84. The mortality was 20.69%. The catheter retention time in hematoma puncture was (4.07±1.49)days, and the catheter retention time in ventricle puncture was (8.17±2.55)days. There were 9 cases of rebleeding and 2 cases of intracranial infection. The differences were not statistically significant (P＞0.05). Conclusions Soft and hard channel minimally invasive interventions of hypertensive cerebral hemorrhage have the same clinical value.

The Telomeric Repeat Amplification Protocol(TRAP)and its modified versions change the size and/or the ratio of the telomerase products in the amplification stage of the assay.Based on TRAP,a useful method was developed for detecting telomerase activity in rice.A special precursor primer and a special reverse primer and conducted two steps of PCR cycles were designed.GENE Genius? Bio-imaging System was applied for this quantitative analysis for exploring telomerase activity and its optimal reaction conditions.The method ensured that the optimal reaction conditions for the telomerase was 19℃,13minutes,at a concentration of 0.28 u g/? l.A quantitative analysis method was established for detecting telomerase activity in rice.With this method,we detected telomerase activity in roots,young leaves and young panicles of six parental lines of hybrid rice.The results show that young panicles have the highest telomerase activity,demonstrating that telomerase activity is closely related to the cell vitality in plants.

Objective To investigate the immunological reaction,serum and liver ?-L-iduronidase(IDUA) activity after human fetal liver cells(FLCs) transplantation therapy on mucopolysaccharidosis(MPS) which attribute to IDUA defect.Methods FLCs were transplanted into IDUA deficiency mice.T cell subsets(CD3,CD4 and CD8) was detected by flow cytometry,while IL-2,TNF-? and IFN-? by ELISA,and serum and liver IDUA activity by fluorospectrophotometer at different stage(before transplantation and 5,10,15 days after transplantation).Results Human FLCs survived in IDUA deficiency mice,bringing elevated serum and liver enzyme activity to receptor.T cell subsets,IL-2,TNF-? and IFN-? was significantly higher 5,10 and 15 days after transplantation than those before transplantation(P
