ABSTRACT
There is still a large number of patients with chronic hepatitis B virus (HBV) infection in China, which greatly affects the health of Chinese people. With the change in lifestyle, the incidence rate of nonalcoholic fatty liver disease (NAFLD) is increasing year by year in China. Some clinical studies have shown that there is a relatively low incidence rate of chronic HBV infection with NAFLD, while there are still reports on NAFLD in promoting the progression of chronic hepatitis B-related diseases. Based on literature search and review, this article attempts to investigate the interaction between HBV replication, abnormal lipid metabolism, and fatty liver disease in patients with chronic hepatitis B and NAFLD, in order to provide ideas for HBV antiviral treatment and prevention of NAFLD.

ABSTRACT
Poly ( aniline_luminol ) composite nanowires were synthesized by chemical oxidation using ammonium peroxydisulfate. In contrast to the maximum fluorescence emitting wavelength of luminol at 425 nm, the maximum fluorescence emitting wavelength of the polymeric luminol in the composite nanowires was red shifted to 465 nm obviously. The poly ( aniline_luminol) composite nanowires were modified on graphite electrode surface by drop coating, forming a stable poly ( aniline_luminol ) composite nanowires film. The composite nanowires film modified electrode presented favorable electrochemiluminescence ( ECL ) performances, and the ECL response could be enhanced by hydrogen peroxide. Under the optimized experimental conditions, the modified electrode provided a linear range of 5. 0×10-9-1. 0×10-5 mol/L for the detection of hydrogen peroxide with a detection limit of 2 ×10-9 mol/L.
ABSTRACT
Objective To investigate the effect of umbilical cord blood dendritic cells(DCs)induced by gastric cancer antigen combined with cytokine induced killer(CIK)cells in gastric cancer cell lines SGC-7901 in vitro. Methods Mononuclear cells from umbilical cord blood were used to create DCs and CIKs. The cell surface antigen expression of the mature DCs such as CD83,CD86,CD11c and the cell surface antigen of CIKs such as CD3,CD56,CD4,CD8,CD16 were detected using flow cytometry. Sensitized DCs-CIKs,DCs-CIKs,CIKs as effective cells,and SGC-7901 as target cells,the killing activities of these effective cells were tested with LDH release,which the number ratio of cells between effective cells and SGC-7901 cells were 10 :1,20 : 1,40 : 1,respectively. Results The cell surface antigen expressions of the mature DCs,such as CD83 + CD86 + ,CD11c + CD83 + ,CD86 + CD11c + were(75. 4 ± 2. 1)% ,(79. 3 ± 1. 4)% ,(80. 2 ± 2. 6)% , respectively. The mature sensitive-DCs surface antigen expressions,such as CD83 + CD86 + ,CD11c + CD83 + , CD86 + CD11c + ,were(77. 7 ± 1. 5)% ,(82. 6 ± 1. 9)% ,(76. 9 ± 2. 6)% ,respectively. There was no sta-tistical significance about the surface antigen expression between DCs and sensitive-DCs(t = 1. 526,P ﹥ 0. 05;t = 0. 958,P ﹥ 0. 05;t = 1. 049,P ﹥ 0. 05). The CIKs surface antigen expressions,such as CD4 + ,CD8 + , CD3 + CD56 + CD16 + ,were(22. 8 ± 1. 3)% ,(77. 3 ± 1. 8)% ,(24. 5 ± 2. 1)% ,respectively. The results suggested that the killing effect of the three kinds of combination cells on gastric cancer cells was different. The number ratio of cells between sensitive-DCs and SGC-7901 cells were 10 : 1,20 : 1,40 : 1,which the killing activities of sensitive-DCs-CIKs against SGC-7901 were(37. 68 ± 1. 49)% ,(41. 67 ± 0. 90)% ,(42. 71 ± 0. 98)% ,respectively. The killing activity of sensitive-DCs-CIKs was the highest when the ratio of cells between sensitive-DCs and SGC-7901 cells were 40 : 1. The killing activities of DC-CIKs were(36. 77 ± 0. 46)% ,(38. 94 ± 0. 95)% ,(41. 15 ± 0. 89)% ,respectively. The killing activities of CIKs were(34. 74 ± 1. 01)% ,(37. 76 ± 0. 43)% ,(39. 65 ± 0. 79)% ,respectively. There were statistically significant differences among the three groups(F = 5. 92,P ﹤ 0. 05;F = 19. 13,P ﹤ 0. 05;F = 8. 88,P ﹤ 0. 05). Conclusion The tumor killing activity of CIK is enhanced obviously by umbilical cord blood DCs which is sensitized by gastric cancer tumor antigen. There is the highest killing activity when the number ratio of cells between sensitive-DC-CIK and SGC-7901 cells is 40 : 1.
ABSTRACT
Inrecentyearsmanytargetedagentstreatinggastriccancerhavebeenevaluatedinclinical studies.Trastuzumab,an anti-HER-2 monoclonal antibody,has shown activity against HER-2-positive gastric cancer and become the first targeted agent approved in gastric cancer.Drugs targeting epidermal growth factor receptor,including monoclonal antibody and tyrosine kinase inhibitor,bring survival benefit to patients with gastric cancer.Addi tionally,vascular endothelial growth factor inhibitors are also under investigation.Other targeted agents are in preclinical or early clinical development,such as m-TOR inhibitors and c-MET inhibi-tors.
ABSTRACT
Cytokine-induced killer (CIK) cells therapy plays an important role in cancer adjuvant treatment.Researches show that the number of peripheral blood immunocytes will change if patients with cancer accept the treatment of CIK cells.The changes of T cell subsets,regulatory T cells are relatively obvious,which may be one of the standards that can evaluate the curative effect of CIK cells.
ABSTRACT
As a useful supplement for TNM staging system of non-small cell lung cancer (NSCLC),circulating tumor cell (CTC) can better reflect the comprehensive condition of the patient.CTC plays an important potential role in monitoring curative effect of lung cancer,and has the effect of real-time detection.With the development of the CTC detection method and the improvement of sensitivity and specificity,clinical studies about CTC will provide more help for prognosis evaluation.
ABSTRACT
Cancer cachexia(CC)caused by cancer is a syndrome with complicated symptoms.Traditional therapies usually give interventions for more nutrition intake at CC late stage and take weight as the outcome marker.Lots of clinical trials demonstrate that the effect is not satisfactory.Recent studies show that the level of NF-KB decreased,termination of the breakdown of myofibrillar proteins,the serum proteins and lean body mass increased and function improvement after targeting proteasome at early stage of CC combined with traditional therapy.
ABSTRACT
Objective To study the safety and efficacy of fast track program in anorectal surgery perioperative period. Methods One hundred and sixty-nine cases of rectal cancer were divided into the study group of 86 patients with fast track program, and the control group of 83 patients with traditional programs by random digits table. Both groups were compared from the time out of bed, the first intestinal discharge time,intravenous fluids stopping time,length of hospital stay,total cost of treatment and the incidence of postoperative complications. Results The study group compared with the control group: the first intestinal discharge time [(33.6 ± 12.9) h vs. (81.7 ± 20.1) h], intravenous fluids stopping time [(4.5 ±1.3) d vs.(7.4 ± 1.6) d],and length of hospital stay [(5.6 ± 1.2) d vs.(8.9 ±2.7) d],the total cost of treatment [(15 000 ± 3000) yuan vs. (16 000 ± 4000) yuan], the differences were statistically significant (P ＜ 0.01 or ＜ 0.05),and had less incidence of postoperative complications in study group than that in control group [5.8% (5/86) vs. 16.9% (14/83)], the difference was statistically significant (P ＜ 0.05).Conclusions Fast track program in anorectal surgery perioperative period is safe and effective, beneficial,conducive to rehabilitation of patients.
ABSTRACT
Objective To investigate the clinical characteristics of severe patients with influenza A H1N1. Methods Fifteen prenant pneumonia patients with influenza A H1N1 were selected from November 26 to December 20,2009. Results The average age of all patients was 24 years old,with an average gestational age of 32 weeks. Leukopenia was observed in 13. 3% of IS patients,and lymphopenia in 86. 7%. Data on the ratio of CD4 cells to CD8 cells were available for 12 patients,54. 5% of whom had an abnormal CD4:CD8 ratio(< 1. 4). Ten of the 14 patients(71. 4%)had increased serum lactate dehydrogenase levels,which were above 245 U per liter. Four patients (26. 6%) had elevated creatine kinase levels at admission. 4 cases of 15 patients (26. 7%) had decreased serum potassium levels,which were below 3.5 mmol per liter. Four patients (33. 3%)had C4 levels higer than 36 g per liter,and 4 cases had C3 less than 0.75 g per liter. All 15 patients had radiologically confirmed pneumonia with bilateral patchy alveolar opacities, affecting three or four lung quadrants. Findings on chest radiographs were consistent with the acute respiratory distress syndrome in all patients requiring mechanical ventilation. 4 cases were found a small amount of pleural effusion, of which 1 case was combined a small amount of pericardial effusion. Respiratory distress requiring intubation and mechanical ventilation developed in 9 patients within the first 24 hours after admission, who were all pregnant women. Two of them in the third trimester died, and 7 cases who were timely terminated pregnancy were in stable condition. Conclusions Pandemic influenza A(HIM) may pose an increased risk of severe illness in pregnant women, and it is easy to develop rapidly into adult respiratory distress syndrome. The pregnancy immunological tolerance may be involved in the severe lung injury process of H1N1 influenza pneumonia.
ABSTRACT
Objective To investigate the related factors of phlebitis caused by PICC and support effective preventive nursing measures. Methods 163 patients diagnosed as malignant tumor who first used peripherally inserted central catheters (PICC) were recruited. Patients were observed for 3 months. According to the diagnostic criterion of infection, 34 patients with phlebitis were divided into the phlebitis group and others were divided into the control group. All patients were investigated for general information survey :sex, age, tumor type, allergic history,location of inserted vein, one-time success rate,activity after catheter, elbow bending,phlebitis occurred time, grade and type. Laboratory markers:WBC,neutrophils,immune parameters, fasting plasma glucose. Trait anxiety inventory (T-AI)was used for assessment of emotional state. Case-control study between groups was carried out. Results The results of univariate analysis showed that location of inserted vein,times of inserting vein,activity of inserted limb,elbow bending,blood sugar level and emotion were associated with phlebitis. Sex, age, tumor type, allergic history, immune function,WBC,neutrophils were not involved with phlebitis. The results of multivariate logistic regression analysis showed that PICC through basilica vein was the protective factor. Multiple insertions, more activity of inserted limb,durative anxious emotion were the risk factors of phlebitis. Conclusions Different location of vein,times of inserting vein,activity of inserted limb,elbow bending,high blood glucose level and persistent anxious emotion are the risk factors of phlebitis. Taking effective preventive measures before,during, and after PICC can reduce the incidence of phlebitis.
ABSTRACT
Objective To investigate the induced-factors levels of venous thrombosis associated with the placement of peripherally inserted central catheters (PICC) in patients with malignant tumor,and establish intervention model accordingly. Methods 40 patients complicated with venous thrombosis after PICC were set as the thrombosis group, 40 patients without venous thrombosis were selected as the no-thrombosis group, 30 healthy cases were selected as the control group. All cases' serum samples were ob-tained to measure the levels of molecular biomarkers of the coagulation system, platelet parameters and molecular biomarkers of the fibrinolysis system. The results of the three groups were assessed. Results Patients in the thrombosis group were reported significantly higher levels of vWF, GMP140,TAT than those in both two other groups, but lower levels of ATⅢ. Higher levels of MPV and PCT were found in the throm-bosis group than those in both two other groups.Tthe data also showed higher PLG and PAI levels and lower levels of PLM in the thrombosis group. Conclusions From this study it shows that patients with malig-nant tumors during the placement of PICC have evident hypercoagnlahility, high- activated platelet and se-vere pre- thrombosis state caused by PICC. In treatment of malignant tumor patients with PICC, the level of coag-ulation system molecular markers, platelet parameters,fibrinolysis molecular markers shoud be used as a clinical routine and as the index of early intervention and evaluation of the PICC.
ABSTRACT
Conspecific organ transplantation provides the survival for the diseased patients at the later stage. The transplantation-induced emotional disorder, rejection, social and psychological burdens all affect the donor, recipients and their relatives, together with the involved medical staff regarding the physical and mental health. The differences of gender, age, cultural background, economic status, social and family roles, and religion beliefs may result in the varying psychological reactions. Therefore, it is recommended to conduct the psychological intervention for the population at each stage of the organ transplantation, as the transplantation technique increases.
