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 analyze the characteristics of hospital infection of hematological disease, so as to provide reference for clinical therapy. Methods: Bacterial strains and antimicrobial resistance of pa-tients with hospital infection in Department of Hematology, Peking University Third Hospital from Jan. 2011 to Dec. 2013 were identified and analyzed retrospectively. The specimens were from their blood, urine, sputum, throat swabs and etc. Results:Among the total of 168 isolates of bacteria,the majority of the bacteria strains were from sputum (42. 9%);114(67. 9%) bacteria strains were gram negative and 54(32. 1%) bacteria strains were gram positive;the pathogen testing showed that 20. 8% were Pseudo-monas aeruginosa,18. 5% Escherichia coli,17. 9% Staphylococcus aureus, 9. 5% Klebsiellar pneumonia, 5. 9% Staphylococcus epidermis and 27. 4% other bacteria ;The gram negative bacilli to cefepime, ami-kacin and carbapenems showed the lowest antimicrobial resistance rates, and S. aureus showed the lowest antimicrobial resistance rates to vancomycin and linezolid. Conclusion:Patients with hemopathy are the main population of hospital infections, the gram negative bacteria are the most common pathogens. It is very important to promptly know the change in distribution of the pathogens in order to rationally select antibiotics and reduce the incidence of bacterial infections.

Objective To investigate the differences between Monte Carlo (MC) calculated doseto-water (Dw) and dose-to-medium (Dm) for lung cancers treated with intensity-modulated radiotherapy (IMRT).Methods A total of 10 lung carcinoma patients with 5-field IMRT treatment plans were stratified sampling randomly selected for this study,which were performed on Monaco treatment planning system (TPS) with MC algorithm.Using the patients' own CT images as quality assurance (QA) phantoms,two kinds of QA plan were calculated,one was the Dm,and another was the Dw plan.Dose volume histogram (DVH) parameters and the subtraction of two plans were used to evaluate the spatial distribution of the difference between the Dm and Dw.Results Differences between dose-volume indices computed with Dm and Dw for the PTV65 and PTV50 doses (D50％,D98％ and D2％) were-0.3％,-0.2％,0.3％ and 0.1％,-0.6％,0.4％,respectively,of which the D50％ of PTV65 and D98％ of PTV50 had statistical difference (t =-2.536,-3.776,P ＜ 0.05).For normal tissues,spinal cord,heart,lung and esophagus,the D50％ differences between Dm and Dw were 0.3％,1.1％,-0.2％ and -0.1％,of which the Dm of spinal cord and heart were slightly lower than the Dw (t =2.535,3.254,P ＜ 0.05).For the D2％ of the normal tissues,the differences were 0.3％,-0.6％,-0.7％ and 0.6％,the differences were statistically significant (t =2.311,-4.105,-3.878,6.214,P＜0.05).All the differences were within 2％.Meanwhile planned subtraction analysis showed the differences between the Dm and Dw varied very much with the other body parts of the patient,especially for bone tissues,and the two doses were significant difference (＞ 5％).Conclusion In the course of clinical application,the relative differences between Dm and Dw for lung cancers MC calculations should be noted when considering the dose limitations of bone tissue.

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 discuss the characteristics and regular patterns of adverse drug reactions (ADRs) induced by Qingkailing injection for references of clinical rational drug use. METHODS:ADR cases induced by Qingkailing injection reported in Chinese pharmaceutical journals from 2003 to 2005 were retrieved and analyzed statistically. RESULTS:The ADRs induced by Qingkailing injection were more often seen in men than in women, with children and young adults showing higher percentages. Allergic reactions were the main type of adverse drug reactions. Of the total ADR cases induced by Qingkailing injection, 22 cases(33.33%) were anaphylactic shock,15(22.73%) were allergic reactions,10(15.15%) were allergy of circulation system. CONCLUSION:The ADRs induced by Qingkailing injection may be resulted form many factors, which should be given fully attention in the clinic. ADRs monitoring should be stressed when this drug being used by western medicine physicians to make sure rational use of which and to reduce incidences of ADRs.

OBJECTIVE:To investigate the situation and characteristics of serious adverse drug reactions (ADR) occurred in our hospital in order to promote rational clinical drug use. METHODS: 25 severe ADR cases collected in our hospital from Jun. 2004 to Dec. 2006 were analyzed statistically and evaluated based on the ADR causality judgment criteria. RESULTS: The 25 severe ADR were associated with 21 kinds of drugs, with anti-infectives (12 kinds) making up the highest proportion, followed by traditional Chinese medicine preparations. The main systems involved in he ADR were skin and its appendages and nervous system. 3 new and severe ADR cases were found to have no report in package inserts or literature. CONCLUSION: Severe ADR may be induced by many factors, therefore, it is necessary to strengthen the awareness of rational drug use to guard against severe ADR and ensure safe and effective medication.
