Objective The aim of this study was to investigate the effects of different anesthetic drugs and techniques on serum SIL-2R, IL-6 and TNF-? in cancer patients undergoing elective thoracic surgery, trying to find a reasonable anesthesia for patients with compromised immune function. Methods Eighteen ASA Ⅰ-Ⅱ cancer patients(male 12, female 6) undergoing elective thoracic surgery were studied. The age ranged from 46-47 years. 6 patients suffered from lung cancer and 12 from cancer of esophagus or cardia. The patients received no radio-or chemotherapy before surgery. They were premedicated with intramuscular pethidine 50mg and atropine 0.5mg. Esophogus and cardia cancer patients were randomly divided into two groups: group Ⅱ and Ⅱ . Group Ⅲconsisted of only lung cancer patients. Group I received general anesthesia combined with continuous epidural block and postoperative epidural analgesia. An epidural catheter was inserted at T7-8 or T8.9 before general anesthesia. Anesthesia was induced with 2% thiopental sodium 5mg kg-1 and vecuronimn 0.06-0 .08mg kg-1 and maintained with 1%-2% isoflurane inhalation with epidural 2% lidocaine 6-7m1o h-1 . After operation epidural analgesia was produced with 0.125% bupivacaine 5-6ml h-1 for 72 h. In group Ⅱ the induction of general anesthesia was the same as in group Ⅰ , but anesthesia was maintained with ketamine infusion 1-2mg kg-1h-1 and epidural 2% lidocaine 6-7ml h-1. Postoperative analgesia was produced with epidural 0.1% bupivacaine + 0.0003% fentanyl 5-6m1o h-1 for 72 h. In group Ⅲ the induction and maintenance of anesthesia were the same as in group Ⅱ but postoperative analgesia was produced with epidural 0.1 % ketamine 4-5ml h-1. Blood samples were taken from peripheral vein before anesthesia, before and 2 h after skin incision and on the 1st, 3rd and 5th day after operation for determination of serum SIL-2R, IL-6 and TNF-? by ELISA(Genozyme Co) Results The serum SIL-2R, IL-6 and TNF-? levels were comparable before anesthesia and operation among the three groups. Serum SIL-2R decreased significantly at 2 h after skin incision(P

Objective To investigate the effect of solution-focused therapy on the care burden and negative emotions of the primary caregivers with elderly patients with hip fractures. Methods One hundred and sixty-eight elderly patients with hip fractures and caregivers were divided into intervention group and control group with 84 pairs by random digits table method, and the two groups were given continual nursing care. At the same time, the primary caregivers of intervention group accepted the solution-focused therapy. Caregiver Burden Inventory (CBI), Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS) were used as the evaluation indexes. Results Before intervention, the score of CBI, SAS,SDS was (42.07 ± 4.24), (50.75 ± 11.21), (51.59 ± 13.18) points in control group and (42.10 ± 3.96), (50.48 ± 12.59), (52.96 ± 13.51) points in intervention group, and there was no significant differences between two groups (P>0.05). After intervention, the score of CBI, SAS, SDS was (40.49±3.17), (50.64±11.33), (50.14±10.25) points in control group and (28.95±2.87), (36.73±9.45), (41.60±8.23) points in intervention group, and there was significant differences between two groups (t=5.42, 8.73, 7.45, all P<0.05). Conclusions Solution-focused therapy can effectively reduce the care burden of the primary caregivers of elderly patients with hip fractures and alleviate their anxiety and depression.

Objective To evaluate the differences of serum TSH of suspicious subclinical hypothyroidism determined by four automatic biochemical analyzers and the impact on clinical diagnosis and treatment.Methods Taking results of Roche Cobas e601 laboratory test as a reference, 103 serum samples with TSH 2.50-10.00 mU/L(90 with TSH≥4.27 mU/L) and normal FT3, FT4 were selected.Four different automatic biochemical analyzers (Cobas e601, Immulite2000, Centaur XP, I2000) were used to measure TSH of the serum samples at the same time.Wilcoxon signed rank test, Spearman correlation analysis were used for data analysis.Results TSH (M(P25, P75)) measured by 4 methods were 5.20(4.73, 6.40), 2.95(2.59, 3.48), 3.30(2.94, 4.15) and 4.10(3.43, 4.75) mU/L, which varied significantly from one assay to another (z values:-8.78,-8.41,-7.64,-8.09,-8.50, all P<0.05).The correlations between methods were of great differences (rs ranged from 0.45 to 0.92).Significant differences existed in each other for subclinical hypothyroidism diagnosis based on TSH cutoff respectively.Conclusion Results from different automatic immunoassay analyzers in patients with TSH of 2.50-10.00 mU/L varied widely, hence, it is indeterminate to diagnose subclinical hypothyroidism only relies on a single serum TSH test.

Objective To investigate the antibiotic-resistant gene mecA and the prevalence of Panton-Valentine leukocidin (PVL) gene, toxic shock syndrome toxin (TSST-Ⅰ) gene in S. aureus. Methods A total of 74 S. aureus were collected from clinical specimens. The mecA, PVL and TSST-Ⅰ genes were detected by PCR.Results PVL gene was identified in 22 S. aureus isolates. The prevalence of PVL was 29.7% in S. aureus, 36.6% in MRSA and 21.2% in MSSA. The difference was not statistically significant (P>0.05). The prevalence of MRSA was 55.4% in 74 S. aureus. The prevalence of TSST-Ⅰ gene was 6.8%. TSST-Ⅰ gene was not detected in MSSA.Conclusions MRSA strains show highly resistant to antibiotics. PVL- and TSST-Ⅰ-positive S. aureus are more pathogenic.

Objective To observe the effects of oldhamianoside Ⅱ on the invasive 'ability of prostatic carcinoma DU-145 cells,and to investigate the potential mechanism.Methods After treatment of DU-145 cells with oldhamianoside Ⅱ,MTT assay was used to test the effect of oldhamianoside Ⅱ on the cell proliferation.The invasive ability was assessed with a transwell cell culture chamber.Immunocytochemistry stain was used to investigate the expression of matrix metalloproteinase(MMP-2)and CXC-chemokine receptor 4 (CXCR4).Results The proliferation of DU-145 cells was inhibited after treatment with oldhamianoside Ⅱ.In vitro invasion assay indicated that the cells moved through the membrane were(180.3 ± 14.6)/field in the control group,while decreased to(100.4 ±1.5),(80.2±2.7)and(60.1 ±5.3)/field in 0.25,0.5 and 1μg/mL oldhamianoside Ⅱ treated DU-145 cells respectively.Comparing to control group,the cells of oldhamianoside Ⅱ groups moved through the membrane were decreased remarkably(P ＜0.05).Immunocytochemistry showed that the expression of MMP-2 and CXCR4 were decreased of oldhamianoside Ⅱ groups.Conclusions Oldhamianoside Ⅱ can inhibit the invasiveness of DU-145 cells,which is related to the down regulation the expression of MMP-2 in DU-t45 cells.Oldhamianoside Ⅱ can inhibit the prostate cancer cells metastasis to the bone,which is related to the down regulation the expression of CXCR4 in DU-145 cells.

Objective To compare the consistence and difference between the assay results of the second generation of Tg (Tg Ⅱ) and the first generation of Tg (Tg Ⅰ) immunoassay,as well as to evaluate the impact of Tg Ⅱ on the clinical management of thyroid diseases.Methods Serum samples of 249 patients (30 with benign thyroid disorders and 219 with DTC;64 males and 185 females,average age 43.0 years)were collected and assayed by Tg Ⅱ and TgⅠ kits simultaneously.The measuring ranges of TgⅠ and TgⅡ were 0.10-1 000.00 μg/L and 0.04-500.00 μg/L,respectively.Data were analyzed by the Wilcoxon rank sum test and Spearman correlation analysis using IBM SPSS 19.0.Results The assay results of TgⅡ and TgⅠ strongly correlated (rs =0.979,P＜0.05).However,the median value of TgⅡ (2.31 (0.06-13.17) μg/L) was lower than that of TgⅠ(3.63(0.41-16.84) μg/L)(z=-13.25,P＜0.001).The difference between Tg Ⅱ and Tg Ⅰ got bigger when TgⅠ value decreased more.TgⅡ values were 11.09％ lower than TgⅠ (5.61(1.07-26.39) μg/L) vs 6.31(2.07-33.93) μg/L;z=-4.78,P＜0.05) in 30 patients with benign thyroid disorders and 37.71％ lower (2.18(0.07-7.47) μ.g/L) vs 3.50(0.39-10.18) μg/L;z=-9.02,P＜0.001) in 108 DTC patients without 131 Ⅰ treatment.But the above changes had no influence on clinical diagnosis and treatment.In the 71 DTC patients post 131Ⅰ treatment with low TSH and normal TgAb,there were 3 cases with TgⅠ＞1.0 μg/L but TgⅡ＜1.0μg/L,and 12 cases with TgⅠ＞0.1 μg/L but TgⅡ＜0.04 μg/L.Conclusions Serum TgⅡand Tg Ⅰ assay results are strongly correlated,though Tg Ⅱ value is slightly lower than Tg Ⅰ value.This difference may have no significant influence on the clinical diagnosis of thyroid diseases.However,TgⅡ may be better to evaluate the curative effect in some DTC patients post 131Ⅰ therapy.
