Operation is always thought to be the soul way to cure hepatocelluar carcinoma(HCC),but there are only 30% patients who have the opportunity to receive the operation.Transcatheter hepatic arterial cheomoembolization is the most extensive non-surgery approach to treat hepatocelluar carcinoma which also has a lot of shortcoming and limitation.It is common sense that enhancement of effectiveness of liver cancer therapy largely depends on the combined therapy.

Purpose To explore the expression of Bmi-1, p14ARF and Mdm2 in colorectal carcinoma and to find out their association with clinicopathological features. Methods The expression of Bmi-1, p14ARF and Mdm2 was detected by immunohistochemistry in 125 cases of colorectal carcinoma and 20 cases of normal colorectal tissues. Results ( 1 ) The positive rates of Bmi-1 and Mdm2 were 56. 8% and 62. 4% in colorectal carcinoma, respectively, which were much higher than that in normal colorectal tissues (20. 0% and 15. 0%). The positive rates of p14ARF was 47. 2% in colorectal carcinoma, which was much lower than that 75. 0% in normal colorec-tal tissues ( P<0. 05 ) . ( 2 ) The expression of Bmi-1 was significantly correlated with serosal invasion, lymph node metastasis and Dukes stage. The expression of p14ARF was significantly correlated with serosal invasion and Dukes stage. The expression of Mdm2 was significantly correlated with histologic grade, lymph node metastasis and Dukes stage (P<0. 05). (3) In colorectal carcinoma, the expression of Bmi-1 and Mdm2 was negatively correlated with p14ARF, respectively (P<0. 05). Conclusions Abnormal expression of Bmi-1, p14ARF and Mdm2 is involved in the occurrence, development and metastasis of colorectal carcinoma, which could be as the reference factors in judgement of biological behavior and provide a new target for clinical treatment.

Objective To explore the change of thyroid hormones and leptin at hyperuricemia (HUA)/gout.Methods A total of 96 primary gouts,65 HUAs,and 59 healthy examiners was selected.Height,weight,blood pressure,renal function,serum uric acid(SUA),glucose,lipid profiles,insulin,thyroid hormones were measured after an overnight fast.Results (1) The prevalence of subhypothyriodism at gout and HUA was 7.29％ and 15.38％,respectively.They were higher than that at healthy subjects.(2) Body mass index (BMI),systolic blood pressure (SBP),triglyceride (TG),cholesterol (CHO),thyroid stimulating hormone (TSH),fasting insulin (FINS),homeostasis model assessment of insulin resistance (HOMA-IR),and serum leptin level were increased remarkably at gout/hyperuricemia relative to control group,whereas,free thyroid hormone (FT4) was decreased.(4) In the gout and hyperuricemia groups,TSH was used as the dependent variable for the linear multivariate regression analysis,the results showed that sex,age,BMI,SUA,FT4,HOMA-IR,and Leptin were included in the regression equation of TSH (βwere-0.27,0.832,0.946,0.198,-0.942,0.895,and 0.650,respectively).Conclusions The prevalence of subhypothyroidism in primary gout/hyperuricemia was increased.Female,age,BMI,SUA,FT4,HOMA-IR,and leptin were the independent risk factors.Insulin resistant and leptin played the media roles in the gout/HUA and hypothyroidism.

Objective To study the correlation of blood drug concentration determination of sodium valproate in children with epilepsy by using enzyme-multiplied immunoassay test (EMIT) and high performance liquid chromatography (HPLC), so as to provide basis of selection in clinical determination of sodium valproate ( VPA) .Methods 200 blood samples of epileptic children taking sodium valproate were collected, blood concentration were determined by EMIT and HPLC method, and the correlation was analyzed.Results The following regression equation was obtained by determination results of HPLC (X) and EMIT (Y): Y=1063.517X-331.351(r=0.933), which had significant correlation (P<0.05).The plasma concentration of VPA determined by EMIT was higher than that by HPLC.Conclusion The determination results of VPA concentration in epileptic children by using EMIT and HPLC has significant correlation, and it should choose the suitable method to determine the blood drug concentration of VPA based on the actual situation.

Objective To evaluate the role of autologous septal cartilage in the rhinoplasty of the wide and bulbous nasal tip. Methods A big piece of autologous nasal septal cartilage was removed and transplanted to the front of nasal septum, acting as a septal extender to fix the nasal alar cartilage,and then the shape of nasal tip was reconstructed by middle crus suture technique, excessive soft tissue under skin of tip and a part of lateral crura cartilage were removed to stand out the shape of the nasal tip. Results After one year follow-up, 118 of 126 cases achieved satisfied effects, but 8 cases dissatisfied because of their undue thick skin. Conclusions This method is reliable in the correction of the wide and bulbous nasal tip.

The patients with diabetic retinopathy (DR) had higher plasma level of soluble E-selectin than those without DR, and the level of soluble E-selectin showed a positive relationship with the extent of DR, suggesting that E-selectin might play a role in the development of DR.

Objective Investigate the clinicopathological characteristics of h?rthle cell tumors of the thyroid. Methods Sixteen cases of HCT were studied by the clinicopathological study and immunohistochemical and review of the literature. Results There were 13 cases of h?rthle cell adenomas, 5 h?rthle cell follicular carcinomas. Immunostains showed that almost all benign and malignant HCT expressed TG, vimentin, S-100 protein. Conclusions HCT is a potential malignant tumor with a defined pathologic feature. It should be follow up for a longer time to their biological behaviors. To distinguish between the benign and the malignant depends on traditional encapsulation, and whether there is a blood vessel invasion or metastasis.

Objective:To produce the mcAb specifically reacting with lung cancer and to purificate its antigen.Methods:The mice were immunized with A549, the mcAb 2B9 was screened by indirect cell ELISA and immunohistochemistry, and its antigen was purificated by immunoaffinity chromatography.Results:A mcAb was obtained, which could react to lung cancer but very little or not to normal lung tissue and other caner tissues, and the antigen of the mcAb was purificated from the cell lysate.Conclusion:A mcAb which can react to lung cancer have been obtained and its antigen was purificated, they may be useful on clinic for diagnosis and prognosis of lung cancer.

Objective To develop an instrument to measure the quality of life (QOL) suitable for Chinese adult patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and evaluate it. Methods A list of 72 items potentially related to QOL of patients with OSAHS was constructed via discussion with OSAHS related people, as well as referring to some foreign QOL instruments. Twenty patients were asked to identify the most significant items. Then, frequency, importance and impact score, which is the product of frequency and importance, of the items were calculated. Those items with an impact score equal to or greater than 1.5 were retained in the instrument. Fifty-two OSAHS patients were divided into two groups based on their apnea-hypopnea index (AHI) (AHI

Objective To transfect PCDNA3.0-HIF1-? into the endothelial progenitor cells(EPCs),in order to provide the foundation for exploring myocardial vascular repairing capacity and angiogenesis of the EPCs transfected with HIF gene.Methods The EPCs were separated by the method of density gradient separation in the human bone marrow,and then the cells were inoculated in the fibronectin-packaged petri dishes complete medium with the concentration of 1?106?mL-1,and cultivated for 14 d. The expressions of the endothelial cell-specific components ecNOS and flk-1 were detected with RT-PCR; the cells were stained with acLDL-Dil and FITC-UEA-1; the PCDNA3.0-HIF1-? plasmid was transfected into the EPCs mediated by LipofectamineTM 2000,the transcription of HIF1-? was determined with RT-PCR; the expression of VEGF was detected with enzyme-linked immunosorbent assay (ELISA); the expression of HIF1-? was detected with Western blotting.Results After cultivated for 5 d,some round monocytes transformated into spindled inherent EPCs;7 d later,there were some cell colonies containing dozens of cells;10 d later,there were obvious cell clones; RT-PCR showed ecNOS band in 548 bp,flk-1 band in 819 bp; acLDL-Dil and FITC-UEA-1 double-staining was positive; RT-PCR showed specific band in 383 bp; ELISA showed the content of VEGF in the supernatant of EPCs transfected with HIF1-? was (20.53?2.33) ?g?L-1,and it was (3.96?1.67) ?g?L-1 in the EPCs transfected without HIF1-?,there was significant difference between two groups (P
