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 laws of acupoint selection of acupuncture for generalized anxiety disorder (GAD); To provide references for clinical treatment.Methods Computers were used to search articles about acupuncture for GAD from China National Knowledge Infrastructure (CNKI), Wanfang Database Resource System, Chinese Scientific Journal Database (VIP database) and Chinese BioMedical Literature (CBM) from their respective founding dates to Dec. 31, 2015. The corresponding database was established with NoteExpress2, and the laws of acupoints were analyzed.Results Totally 41 articles were included, including 56 acupuncture prescriptions, involving 50 acupoints in 14 meridians. The frequency for acupoint selection was 287 times. There were 49 main acupoints (225 times of acupoint selection, accounting for 98.0%) and 23 matching acupoints (62 times of acupoint selection, accounting for 46.0%) in the treatment of GAD. Main acupoints with high frequency were Baihui (GV20), Shenmen (HT07), Neiguan (PC06), Sanyinjiao (SP06) and Yintang (GV29). Matching acupoints with high frequency were Zusanli (ST36), Taichong (LR3), Neiguan (PC06), Shenmen (HT07), and Fenglong (ST40). Selecting acupoints along meridian mainly depended on Governor Meridian, Taiyang Bladder Meridian of Foot, Shaoyin Heart Meridian of Hand and Jueyin Pericardium Meridian of Hand.ConclusionPrinciples of acupuncture for GAD is treatment determination from heart and brain, emphasizing syndrome differentiation and identification of diseases, and the clinic mainly adopts acupoints along meridian with symptomatic acupoints treatment.

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

Objective To prepare the human bone sialoprotein (BSP) monoclonal antibodies (mAb)with high titer and specificity and identify its characterization,which is based on further studying BSP as clinical biomarker for breast cancer metastasizing to bone. Methods BALB/c mice were immunized with purified recombinant BSP protein.Cell fusion was performed between mouse splenic cells and myeloma cells (Sp2/0), and then the hybridoma cell lines secreting mAb against BSP antigen were screened and cloned. The ascites were prepared and purified with Protein G affinity chromatography.The titer and subtypes of mAb against BSP were identified and measured by ELISA and Western blotting analysis. ResultsNine hybridoma cell lines that stably secreted mAb against BSP were successfully obtained.Two of them,D001 and D002,were further identified, which belonged to the subtypes of IgG1 and κ light chain. The two antibodies titers in culture supernatant were 1∶5120 and 1∶10 240, respectively, and those in the ascites fluid were 1∶25 600 and 1∶51 200,respectively.Results of Western blotting analysis and immunohistochemistry showed that the two antibodies could specifically bind with BSP derived from human breast cancer cells.ConclusionNine mAb against BSP have been successfully prepared which can be used for further studying the biological properties of BSP and reveal its relationship with data from clinic patients.

Objective To retrospectively analyze the therapeutic effect of wide surgical excision combined with low-dose adjuvant interferon-alpha 2b on cutaneous malignant melanoma.Methods A total of 32 patients with cutaneous malignant melanoma received wide surgical excision after preoperative examination and staging.The excisions were performed with a margin measuring 1-2 cm from the visible lesions or biopsy scars.Surgical modalities included direct suture after excision(4 patients),dactylolysis or toe amputation(6 patients),free skin grafting(15 patients),random skin flap transfer(3 patients)and pedicle skin flap transfer(4 patients).Lymph nodes were selectively dissected in 9 patients with regional transfer of lymph nodes,and inguinal lymph nodes were cleared away in 2 patients.One week after the operation,patients received adjuvant therapy with subcutaneous injection of interferon-alpha 2b(3 million IU,thrice per week)for one to three years.Results Preoperative tumor staging revealed 21 cases of cutaneous malignant melanoma at stage Ⅱ,and 11 cases at stage Ⅲ.The excisions healed by the first stage in all the patients.Up to June 2011,2 patients had been lost to follow up,5 patients with stage Ⅲ melanoma had died.Survival was observed in all of the 4 patients receiving 1-year follow up,12 of 13 patients receiving 1-3 year follow up,5 of 7 patients receiving 3-5 year follow up,and 4 of 6 receiving 5-year follow up.Of the 25 surviving patients,regional lymph node metastasis was observed in 8 patients,which developed within 2 years after the operation in 2 patients.The adjuvant therapy with interferon-alpha 2b lasted 3 years in 8 patients,and more than 1 year in 11 patients.Side effects were mild.Conclusion Wide surgical excision plus low-dose interferon-alpha 2b is effective for the treatment of stage Ⅱ and Ⅲ cutaneous malignant melanoma with lower local recurrence and higher survival rate.

The clinical data and routine biochemical parameters of 64 maintenance hemodialysis (MHD)patients and 20 controls were analyzed in the study.Serum cystatin C levels were detected by latex particle enhalice inununo-turbidimetry:and the cardial structure and function were assessed by echocardiography.As MHD time extended,the levels of semm cystatin C increased gradually,accompanied with high incidence of left ventricular hypertrophy(LVH).The LVH-positive patients had higher systolic blood pressure and left veHtricular mass index,and had higher serum cystatin C than tllose in LVH-negative patients.The serum cystatin C levels were positively correlated with left yentricular mass index(r=0.633,P<0.01)and systolic blood pressure(r:0.397,P<0.01).The results suggest that serum cystatin levels may be an influencing factor for long-term cardiacvascular complication in MHD patients.

Objective To investigate the impact of high plasma LDL-C level with or without metabolic syndrome(MS) on the incidence of stroke in Chinese adults. Methods Totally 42 626 subjects (25 -75 years old) from Chinese National Health and Nutrition Survey in 2002 were stratified four groups based on plasma LDL-C level: < 2. 00 mmol/L group, 2. 00 -2. 50 mmol/L group, 2. 51 -3.31 mmol/L group, and ≥ 3.32 mmol/L group. The prevalence of MS (with 2005 International Diabetes Federation criteria) and stroke and the risk factors of stroke were compared among the four groups. Results ( 1 ) The prevalence of MS and stroke increased with rising of LDL-C level. The prevalence of MS in LDL-C≥3. 32 mmol/L group increased 2. 5 times (7, 9% vs 20. 1% ) as compared with that in LDL-C < 2. 00 mmol/L group and the prevalence of stroke increased 4. 2 times(0. 5% vs 2. 1% ), all P <0. 01. (2) In subjects with similar LDL-C level, the prevalence of stroke was significantly higher in a subgroup with MS than that without (P <0. 01 ). (3) After adjustment for age, sex and smoking, logistic regression analysis showed that both LDL-C level and MS were positively associated with the development of stroke; the odds ratio (OR) was 2. 35 and 3. 15 ( P < 0. 0001 ), respectively. (4) Compared with the subgroup of LDL-C < 2. 00 mmol/L without MS, OR for stroke in the subgroups of LDL-C 2. 00 -2. 50 mmol/L, 2. 51 -3. 31 mmol/L, and ≥ 3. 32 mmol / L without MS was 1.03, 1. 89, and 2.08, whereas the OR for stroke in the subgroups with MS and similar level of LDL-C was 4. 38, 5.23 and 6. 15 ; this indicated that the risk of stroke in subjects with MS increased by 3 - 4 times compared with subjects without ( P < 0. 0001 ). Conclusion Both high LDL-C level and MS are independent risk factors of stroke, but the risk of stroke will be further increased in the presence of high LDL-C level plus MS. It is suggested that combined intervention therapy of LDL-C and MS will play an important role in the prevention of stroke.

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.
