Objective To study the level and clinical value of differential display code 3 (DD3) in peripheral blood of patients with prostate cancer.Methods 27 patients with prostate cancer from April 2014 to April 2015 in Affiliated Hospital of Hangzhou Normal University were researched.26 patients with non prostate diseases were selected as control group.DD3 mRNA levels were detected in peripheral blood of all patients.DD3 absorbance value of three groups of patients,the relationship between the relative content of DD3 mRNA and the clinical characteristics of prostate cancer,DD3 mRNA in urine and peripheral blood of patients with prostate cancer and benign prostatic hyperplasia were observed.Results In the patients with benign hyperplasia of prostate and non prostate diseases,a total of 4 patients did not appear to be DD3 specific bands.In prostate cancer patients,all patients were found to have DD3 specific bands.The relative content of patients with non prostate diseases was (0.18 ± 0.05) copies/mL.The relative content of benign prostatic hyperplasia patients was (0.30 ± 0.09) copies/mL.The relative content of prostate cancer patients was (0.78 ± 0.23) copies/mL.The positive expression rates of DD3 mRNA in peripheral blood and urine of patients with prostate cancer were 85.18％ (23/27),51.85％ (14/27),respectively,which were significantly higher than those in patients with benign prostatic hyperplasia[21.42％ (6/28),7.14％ (2/27)] (x2 =22.416,13.319,all P ＜ 0.05).Conclusion The specific expression of DD3 mRNA in peripheral blood of patients with prostate cancer can be used as an effective basis for judging the patients' condition,and it has certain value for the treatment and prognosis of patients with prostate cancer.

Objective To evaluate the effect of lobe bronchus blockade with a branchial blocker on intrapulmonary shunt during radical esophagus cancer resection. Methods Twenty four ASA Ⅰ-Ⅲ patients with normal lung function aged 18-69 yrs undergoing elective radical esophagus cancer resection were randomized into 2 groups ( n = 12 each): group A one-lung ventilation (OLV) and group B lobe bronchus blockode. Radial artery and right internal jugular vein were cannulated for BP and CVP monitoring and blood sampling. Anesthesia was induced with midazolam 50 ?g?kg-1, fentanyl 4 ?g?kg-1, propofol 2 mg?kg-1 and vecuronium 0.1 mg?kg-1. In group A double-lumen tube (DLT) was used while in group B a single lumen endotracheal tube was placed first, then a bronchial blocker was inserted fiberoptically into the bronchus of lower lobe of the operated side. The patients were mechanically ventilated (FiO2= 100%, VT = 8 ml?kg-1 , RR = 10-15 bpm, I: E = 1:2). PaCO2 was maintained at 30-35 mm Hg. Anesthesia was maintained with 1.5%-2.0% isoflurane and intermittent Ⅳ boluses of fentanyl and vecuronium. BP, HR, CVP, SpO2, PETCO2 and airway pressure were monitored during operation. Blood samples were taken simultaneously from radial artery and central vein for blood gas analysis before induction of anesthesia when the patients were lying supine and breathing spontaneously (T0), after the lungs on both sides were ventilated for 30 min in lateral position (T1) and 30 min after OLV (group A) or lower lobe bronchus was blocked off (group B) in lateral position (T2). Qs/Qt was calculated (blood from central vein was used instead of mixed venous blood from pulmonary artery) . Blood concentrations of TXB2 and 6-k-PGF1 were determined by radioimmunoassay at T0, T1 and T2. Results There was no significant difference in demographic data between the two groups. At T2 the airway pressure in group A was significantly higher than that in group B. At T2 PaO2 was significantly higher in group B than in group A. Qs/Qt was significantly increased at T1 and T2 as compared to the baselines in both groups. Qs/Qt was significantly increased at T2 compared to that at T1 in group A only, while there was no significant difference between Qs/Qt at T1 and T2 in group B. The TXB2 concentration at T2 was significantly increased as compared to that at T0 and T1 in group A and was significantly higher than that at T2 in group B. Conclusion Lower lobe bronchus blockade was superior to OLV in terms of Qs/Qt and PaO2 during esophagus cancer resection.

BACKGROUND:Clinical limb ischemia-reperfusion with no reflow phenomenon after vascular injury repair seriously affects the prognosis of patients. Therapeutic effect of hyperbaric oxygen in myocardial ischemia reperfusion is exactly confirmed, but hyperbaric oxygen is rarely reported in the treatment of limb ischemia-reperfusion.
OBJECTIVE:To detect the expression of vascular endothelial growth factor and intracellular adhesion molecule 1 and to investigate the effect of hyperbaric oxygen on the prognosis of limb ischemia-reperfusion with no reflow phenomenon.
METHODS:By clinical screening, cases of main arterial injury of the limbs were selected and subjected to vascular repair for restoring limb blood supply. After surgery, al the cases were randomly divided into two groups (Combined treatment group and surgical group), 16 cases in each group. Combined treatment group was treated with hyperbaric oxygen combined with clinical anticoagulant, antiplatelet treatment;surgical group treated with only postoperative clinical treatment. Another 16 adult healthy volunteers were selected to receive hyperbaric oxygen as hyperbaric oxygen group. Expressions of vascular endothelial growth factor and intracellular adhesion molecule 1 were detected using enzyme-linked immunosorbent assay at 8, 72 hours and 7 days after surgery.
RESULTS AND CONCLUSION:In the combined treatment and surgical groups, patients exhibited higher expressions of vascular endothelial growth factor and intracellular adhesion molecule 1 than those in the hyperbaric oxygen group (P<0.01). After 72 hours, the expression of vascular endothelial growth factor was significantly higher in the combined
treatment group than the surgical group (P<0.01). At 8 and 72 hours, the expression of intracellular adhesion molecule 1 was lower in the combined treatment group than the surgical group (P<0.05). These findings suggest that hyperbaric oxygen can induce high expression of vascular endothelial growth factor and inhibit intracellular adhesion molecule 1, which is crucial for improving growth of blood capil ary, formation of endothelial cells, reducing no reflow phenomenon.

ObjectiveTo compare the therapeutic effect, adverse effects and safety of leflunomide (LEF)and cyclophosphamide(CTX) on lupus nephritis(LN). Methods43 patients with reactive LN were randomly divided into two groups. Based on hormone application,22 cases in LEF group were given LEF orally and 21 cases in CTX group were given CTX intravenous drip discontinuously. They were followed up for six months. The related indexes and possible concomitant adverse effects were detected. ResultsThe total effective rate in LEF group was 81.8％ and that in CTX group was 85.7％. The tolerance in LEF group was better and 3 cases had adverse effects. 13 cases in CTX group had adverse effects. ConclusionLEF had the same efficacy as CTX in the LN therapy, but the tolerance is better and the side effects are minor than CTX.
