Objective_To explore the effect and the mechanism of isoflurane on human cardiac myocytes ( HCM) injury induced by anoxia/reoxygenation ( AR) .Methods_HCM cells were divided into control group ( con) , an-oxia/reoxygenation group (AR) and isoflurane (0.5%, 1%, 1.5%and 2%) treatment group (n=6).Cell via-bility, LDH activity, apoptosis and the expression level of Anoxia inducible factor-1α( HIF-1α) were detected using CCK-8 assay, LDH activity assay kit, Annexin V-FITC/PI staining, PCR and western blot, respectively. Results_Compared with the con group, cell viability decreased, LDH activity and apoptosis cells increased in AR group.Isoflurane can significantly relieve the decrease of cell viability, the increase of LDH activity and apoptosis cells, and the down-regulation of the mRNA and protein expression level of HIF-1αinduced by AR ( P<0.05 ) . Compared with AR group, the mRNA and protein expression level of HIF-1αin siRNA transfected group signifi-cantly decreased (P<0.05).2%isoflurane significantly relieve the increase of cell viability, the decrease of LDH activity and apoptotic cells induced by HIF-siRNA in AR injuried HCM cells(P<0.05).Conclusions_Isoflurane can protect HCM cells from AR injury partly through up-regulate the expression of HIF-1α.

Objective:To investigate the effect of continuous blood purification on the expression of cytokines in pig lungs during MODS.Methods:Twenty-five pigs were randomly divided into model group,control group and high volume hemofiltration(HVHF) group.Blood bio-chemical and organ function indexes were determined.Real-time quantitative PCR was used to determine the expression level of IL-6 mRNA and IL-8 mRNA and TNF-? mRNA. Results:After HVHF,the serum chemical and organ-function indexes were improved and the morbidity and mortality of MODS were much lower than those in model group.The expression level of IL-6 mRNA and IL-8 mRNA and TNF-? mRNA in the lung were reduced significantly compared with model group.And the expression level of cytokines associated mRNA in the lungs was interrelated with the rate of respiratory failure. Conclusion:HVHF could decrease the over-expression of cytokine mRNA in the lung after trauma when used at early period so that pulmonary function would be improved.

ObjectiveTo study the correlation of urinary iodine and thyroid function in elderly men in Harbin,and to provide the basis for formulation of health measures for the elderly.MethodsSeventy five cases of clinically healthy elderly men were enrolled for check-up of urinary iodine,thyroid function and B-ultrasound in Geriatric Ward the Forth Affiliated Hospital of Harbin Medical University in 2010.The subjects of investigation were divided into iodine appropriate and iodine sufficient groups and thyroid function parameters and B-ultrasound results were compared.ResultsThe average age of the 75 cases of healthy elderly men was (79.07 ± 4.78) years old and the median of urinary iodine was 198.4 μg/L.There were 62.67％ (47/75) elderly males whose iodine nutritional status was appropriate,but there were still some individuals(6.67％,5/75) in the iodine excess state.The level of TSH of the iodine appropriate group [(1.91 ± 0.82)mU/L] was lower than that iodine sufficient group [(4.98 ±0.60)mU/L,t =12.58,P ＜ 0.05],while the level of FT3 of the iodine appropriate group[(4.71 ± 0.56)pmol/L]was higher than that iodine sufficient group[(3.31 ± 0.43)pmol/L,t =12.18,P ＜ 0.05].But the difference of FT4between the two groups [(14.91 ± 3.12),(14.06 ± 2.79)pmol/L] was not statistically significant (t =1.40,P ＞0.05].The thyroid volume of iodine sufficient group[(20.9 ± 6.1 )cm3] was higher than that iodine appropriate group [(17.9 ± 5.6)cm3,t =2.11,P ＜ 0.05].ConclusionsSufficient quantities of iodine intake may affect the thyroid of elderly people.Whether the quantity of iodine intake of the elderly population should be decreased or not need to be further studied.

Objective　To investigate the prognosis in risk of ventricular arrhythmia in coronary heart disease with heart rate variability (H RV), left ventricular ejection fraction (LVEF) and other clinical background dat a. Methods　A total of 81 patients were divided into ventricular premature beats (VPBs)≥30/h group and VPBs<30/h group. Their LVEF, HRV and cli nical data were studied and analyzed. Results　The age and blood pressure between 2 groups had no significant difference. LVEF, standard deviati on of all normal RR intervals (SDNN), SD of the average of NN interval (SDANN) a nd HRV triangular index (HRVI) were significant less in VPBs≥30/h group than in VPBs<30/h group (43.29±15.38 vs 67.33±11.47，P＜0.01；90.05±22.2 9 vs 117.90±30.32，P＜0.05；77.43±17.78 vs 105.69±28.79，P＜0.05 ；24.54±8.70 vs 32.70±10.87，P＜0.05, respectively). Incidence of myo cardial infarction (MI) was larger in VPBs≥30/h group than VPBs<30/h group. LVE F was the independent predictable factor in risk of ventricular arrhythmia with multinomial regression logistic analysis（B=0.119, P=0.032）. Co nclusion 　Our findings indicate that LVEF is an independent predictable factor i n risk of ventricular arrhythmia in coronary heart disease. Although HRV and MI history can not be used to predict VPB, significant difference is found between 2 groups. High-risk patients could be selected successfully when these data are considered in combination.

Objective To explore the safety and short?term efficacy of irreversible electroporation (IRE)ablation which is a novel ablation technology in unresectable hepatic neoplasms. Methods Patients with pathologically diagnosed as liver cancer or liver metastases were prospectively enrolled. The patients were not suitable for surgery with PS score ≤ 2. Exclusion criteria included who was not tolerate general anesthesia, severe liver and kidney dysfunction, and with cardiac pacemaker. A total of 16 patients were included in this study. There was 12 males and 4 females, aged 40 to 86 years with mean age (60 ± 10)y. Ultrasound and CT guided percutaneous IRE ablation was performed. Perioperative hemodynamic changes were reviewed. Liver and kindey function before and 7 d after ablation was compare by t test. The adverse reactions within 30 d after ablation treatment were recorded. CT and MR scans within 1 month were performed and the 30 d curative effect was evaluated by the modified RECIST criteria. Results All patients received IRE treatment successfully, and some patients experienced adverse reactions within 30 days after ablation, including abdominal pain in 7 cases, peritoneal effusion in 5 cases, hydrothorax in 4 cases, fever in 3 cases, cough, nausea and vomiting in 2 cases, biliary tract infection and thrombocytopenia in 1 case. After symptomatic treatment, these symptoms were improved. Severe complications, such as massive haemorrhage and bile leakage didn't occur. At 30 days after ablation, the curative effects were evaluated. Complete response (CR) was achieved in 1 patient , partial response (PR) was achieved in 12 patients, stable disease (SD) was in 2 patients , and progressive disease(PD) was 1 patients . The tumor relief rate (complete response+partial response) was 81.3%. Conclusions IRE ablation in the treatment of unresectable hepatic malignant tumor could have many advantages, including high safety, mild adverse reactions, and short?term efficacy. However, its long?term effect still need further observation.

OBJECTIVETo investigate the effects of intensive insulin therapy on insulin resistance(IR) and serum proteins after radical gastrectomy.

METHODSTwenty-two gastric cancer patients were randomly divided into the control (n=11) and intensive insulin therapy group (n=11), and underwent distal radical subtotal gastrectomy under epidural anesthesia. Fasting blood glucose (FBG), fasting insulin (FINS) and serum proteins were assayed preoperatively and at day 1, 3, 7 postoperatively. Insulin resistance index was calculated using homeostasis model assessment (HOMA). The length of hospital stay and postoperative complications were recorded respectively.

RESULTS(1)The levels of FBG, FINS, lnHOMA-IR (P<0.01,P<0.05) and the incidence of insulin resistance were remarkably decreased by intensive insulin therapy after the surgical procedure.(2)The levels of serum transferrin (TRF), prealbumin (PRE) and retinal binding protein (RBP) in the intensive insulin therapy group were significantly improved as compared to control group after operation(P<0.05). (3) The duration of fever, antibiotic use, passage of gas by anus, length of hospital stay and the occurrence of postoperative complications were also significantly lower than those in control group(P<0.01,P<0.05).

CONCLUSIONCompared to routine therapy, the intensive insulin therapy has more beneficial effects on the patients undergone distal radical subtotal gastrectomy in decreasing the insulin resistance, improving the status of nutrition and preventing postoperative complications.
