Microwave ablation(MWA) is a significant progress in tumor non-surgical treatment in the 1990s.It is characterized by high thermal efficiency,fast heating rate,high uniform temperature field,complete necrosis of coagulation area and small influencing factors.The local treatment of the tumor shows a great advantage.In recent years,with the maturity of MWA technology,it has been widely used in the treatment of liver tumors(hapatic tumor,HT),has achieved good clinical efficacy.The aim of this study is to review the progress of treatment of HT in MWA to improve its therapeutic efficiency.

Aim To investigate the mechanism of dia-betes changing the hepatic CYP1 A2 through in vitro cell culture study.Methods The function of CYP1 A2 in HepG2 and Fa2N-4 cells were evaluated by determi-ning the level of phenacetin metabolism,and the mR-NA expression of CYP1 A2 in cells was detected by real time PCR.HepG2 cells were co-cultured with serum of diabetic rats(type 1 and type 2)and normal rats,then the CYP1 A2 function in cells were evaluated.Then, the HepG2 and Fa2N-4 cells were co-cultured with a series of concentrations of saturated (including palmitic acid and stearic acid)and unsaturated fatty acids(in-cluding oleic acid and linoleic acid)for 48 h,and the function and expression of CYP1 A2 in the cells were compared.Results It was found that the activities of CYP1 A2 were higher in cells incubated with diabetic serum of both type.All high concentration of fatty acids could increase the function and expression of CYP1 A2 in both HepG2 and Fa2N-4 cells.Conclusion It is speculated that the abnormal level of fatty acids under diabetic state might be part of the reasons why diabetes change the hepatic CYP1 A2,which provides the basis for future study.

Objective To explore the atopic condition of children with stable asthma and their parents by detecting total IgE concentration in serum and collecting history. Methods Fifteen children with asthma in remission stage and 24 parents and 40 normal children were involved in this study. The concentrations of serum total IgE were measured with UniCAP Pharmacia system. The history including eczema and allergic rhinitis and asthma of children and parents were collected. Skin test with 10 kinds of inhalant allergens were taken in children with asthma. Results Of 15 children with asthma, 13 cases (86.7%)had eczema in infant stage and allergic rhinitis, 13 parents(86.7%)had allergic rhinitis or asthma. There was significant difference in the stable asthmatic children compared with parents and normal control group increased amounts of serum total lg IgE(F=68.42 P=0). There was significant difference in serum total lg IgE in patients group(2.43?0.73)kU/L compared with that in normal control group(0.72?0.54)kU/L (q=14.176 P0.05). Twelve children were positive in skin test, which were mainly dermatophagoides pteronyssinus and dermatophagoides farinae.Conclusions There is obvious congregate phenomena of atopy in the family of asthmatic children. The continuous high IgE concentration was associated with immune pathological mechanisms of atopic diseases.

Objective To investigate the influence of alprostadil on renal function,oxidative stress,and immune function in early diabetic nephropathy patients.Methods Eighty-six cases of early diabetic nephropathy patients in our hospital during April 2013 to January 2016 were chosen as research subjects,all patients were divided into observation (n =43) and control (n =43) groups according to random data form.Patients in observation group received alprostadil combined with pioglitazone treatment and those in control group received pioglitazone treatment only,both lasted for one month.Before treatment,one month after treatment,renal function indices were detected;serum oxidative stress indices were detected by automatic biochemical analyzer;T lymphocyte subsets in peripheral blood were measured by flow cytometry.Results Before treatment,there were no significant differences in renal function,oxidative stress,immune function between two groups (P ＞ 0.05).One month after treatment,peripheral blood renal function indices such as blood urea nitrogen (BUN),estimated glomerular filtration rate (eGFR),and cystatin C (CysC) levels were lower in observation group than in control group,the level of serum albumin (Alb) was higher in observation group than in control group,the difference was statistically significant (P ＜ 0.05);semm oxidation indices malondialdehyde (MDA),and advanced oxidation protein products (AOPP) were lower in observation group than in control group,human antioxidant indices such as superoxide dismutase (SOD),and total antioxidant capacity (T-AOC) were higher in observation group than in control group,the difference was statistically significant (P ＜ 0.05);peripheral blood CD3 +,CD4 + T lymphocytes and the ratio of CD4 +/CD8 + were higher in observation group than in control group,CD8 +T lymphocyte level was lower in observation group than in control group,the difference was statistically significant (P ＜ 0.05).Conclusions Alprostadil can optimize the renal function and immune function in early diabetic nephropathy patients,reduce the degree of oxidative stress.

Objective To explore the changes of interleukin-13(IL-13) and total immunoglobulin E(IgE) levels in children with stable asthma.Methods Eighty-eight cases of children with asthma in remission stage aged 6-14 years old and 40 normal children were involved in this study.The concentrations of serum IL-13 and total IgE were measured with enzyme linked immunosorbent assay(ELISA) method and UniCAP pharmacia system.Results Clinical evaluation and lung function were improved in asthmatic children.Serum IL-13 level of asthmatic children in remission stage was higher than that of control group(U=3.93 P0.05).Conclusions There exists continuous allergic inflammation for children with asthma in remission stage.The high concentrations of serum IL-13 and IgE are associated with immune pathological mechanisms of asthma.

Because of the population aging,the increase of the stroke patients and the need for rehabilitation,the treatment only in the rehabilitation department of the hospital is far from the satisfaction of people's demands of the service of rehabilitation.It is important to extend the community-based rehabilitation.Compared with the rehabilitation in hospitals,it is more economy,efficiency and convenience for stroke patients in community-based rehabilitation services,and further improve the rehabilitation effect of stroke patients.

Objective To assess the left ventricular function of patients with acute myocardial infarction (AMI) and its correlation with cardiac troponin T (cTnT) and specific manifestation of electrocardiogram (ECG) by automated function imaging (AFI) of two-dimensional speckle tracking imaging.Methods Forty-six AMI patients who had AMI for the first time and had been treated by primary percutaneous coronary intervention and 30 healthy controls who were age and sex-related to infarct group were involved.The values of cTnT within 24 hours after admission of AMI patients were recorded and the values of ST segment elevation were measured accurately.All the subjects were analyzed for longitudinal peak systolic strain (LPSS) values and the bull' s eyes by AFI.Results Compared to control group, left ventricular ejection fraction (LVEF), global and infarcted LPSS of infarct group were significantly different and the values of ST elevation of infarct group were higher than those of control group.Both global,infarcted segmental LPSS were significant closely correlated to LVEF and cTnT,respectively (P＜0.001,all).Both global, infarcted segmental LPSS were correlated to ST elevation (P ＜0.05,all).Global LPSS had the closest correlation with LVEF (r = -0.565, P＜0.001) and so did infarcted LPSS with cTnT (r = 0.432, P ＜0.01).Conclusions As a procedural simple and rapid diagnostic tool,AFI provides reliable and useful information of the assessment of AMI.Both global and infarcted segmental LPSS have well described left ventricular function of AMI patients.Compared to LVEF, LPSS was more closely correlated to cTnT and ST segment elevation, which meant that LPSS was more sensitive and more closely related to real infarct size and actual involved range of AMI.

Objective To assess the correlation between time during admission to percutaneous coronary intervention (PCI) and left ventricular function recovery of acute myocardial infarction (AMI) by two-dimensional speckle tracking imaging (STI).The clinical value of STI in assessing therapeutic effect of AMI treated by PCI and estimation of the prognosis were discussed.Methods Sixty-one AMI patients who had AMI for the first time and had been treated by primary PCI were enrolled.Dynamic images were acquired before PCI,at 7 days after PCI and 30 days after PCI and analyzed by STI.The time during admission to PCI of AMI patients was recorded accurately.Dynamic images were analyzed for longitudinal peak systolic strain (LPSS) values (global,infarcted area) by STI.According to the comparison of left ventricular ejection fraction(LVEF) before PCI and 30 days after PCI,patients were divided into left ventricular function improved group (ΔLVEF≥5 ％) and not-improved group,and the values of LPSS and time during admission to PCI were compared between the two group respectively.Results Compared to not-improved group,the time during admission to PCI in improved group was lower ( P ＜0.001),infarcted segmental LPSS at 7 days after PCI ( P ＜0.05) and both global ( P ＜0.001) and infarcted segmental LPSS ( P ＜0.001) at 30 days after PCI in improved group were higher than those in not-improved group.Linear regression analysis showed that both global and infarcted segmental LPSS were significant correlated to LVEF respectively ( P ＜0.001,all).Infarcted segmental LPSS at 7 days after PCI were correlated to the time during admission to PCI ( P ＜0.05).LVEF ( r =0.303,P ＜0.05),global ( r =0.300,P ＜0.05)and infarcted segmental LPSS ( r =0.590,P ＜0.001) at 30 days after PCI were correlated to the time during admission to PCI.Conclusions STI provides reliable and useful clinical information for the assessment of therapeutic effect of AMI treated by PCI and estimation of the prognosis by sensitively presenting the close correlation between time during admission to PCI and left ventricular function recovery of AMI patients.

Objective To assess left ventricular(LV) longitudinal strain in patients with coronary heart disease by two-dimensional speckle tracking imaging (2DSTI),and to explore the clinical value of 2D longitudinal strain in detecting myocardial ischemia. Methods Forty-four patients with coronary heart disease (CHD group) and 28 age-matched subjects (control group) were enrolled into this study. The two-dimensional data were obtained in apical 4-chamble, 2-chamber and long axis view. And the longitudinal strains of every segments, the average longitudinal strain of LV 18 segments (SL18), the average longitudinal strain of 12 segments (SL12,excluded the 6 apical segments) were analyzed. Results In the patients with CHD, the longitudinal strain of ischemia segments and the global LV longitudinal strain were significantly decreased than that of the control subjects. Both in patients with CHD and in control subjects,the longitudinal strains in apical segments were higher than that of middle and basal segments. There was significant difference between SL18 and SL12 ( P=0.027 in CHD group and P =0.003 in control group).Receiver operating curve (ROC) analysis demonstrated that the cutoff point of SL18 to detect myocardial ischemia was - 18.8％ (sensitivity 80.2％ and specificity 74.1％ ) ,and the cutoff point of SL12 to detect myocardial ischemia was - 17.8％ ( sensitivity 81.7％ and specificity 85.6％ ). Conclusions 2D longitudinal strain was sensitive to detect myocardial ischemia, SL12 was better than SL18 in detecting myocardial ischemia. 2DSTI might be useful for identifying patients with severe CHD.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.
