Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) was a common complica-tion of small cell lung cancer (SCLC). Recent studies have suggested that the origin of this disease is related to seceration of tumor cells and application of medecine. The inappropriate antidiuretic hormone secretion can lead to disturbance of metabolism of water and sodium, resulting in hyponatremia. Because the symp-toms are atypical, the diagnosis is difficult. Many cases are misdiagnosed or misseddiagnosed. The primary tumor must be treated and the restriction of water intake is the main and effective method to deal with SIADH. Prognosis of SCLC patients with SIADH is poor in most reports.

ObjectiveTo discuss the application of medical elastic stockings in nursing of patients with deep venous thrombosis formation. Methods62 patients diagnosed as acute lower limbs deep ve-nous thrombosis from January, 2005 to January, 2008 were randomly divided into the experimental group and the control groups with 31 patients in each group, the control group took general nursing measures, the experimental group used the medical elastic stockings based on the general care measures, The inci-dence of post- thrombosis syndrome was observed in two groups and underwent χ2 test. ResultsAfter two years follow- up, 2 patients relapsed and 3 patients appeared post- thrombosis syndrome in the experimental group, 8 patients relapsed and 10 patients had post-thrombosis syndrome in the control group. The relapse rate and incidence rate of peat-thrombosis syndrome in the control group were higher than those of the experimental group. ConclusionsThe use of medical elastic stockings can prevent acute lower limbs deep venous throm-bosis, and can reduce the symptoms of post-thrombosis syndrome, which deserves to be spread widely.

Objectives: To compare the efficacy of patient-controlled epidural analgesia and patient-controlled intravenous analgesia in postoperative analgesia after spinal fusion. Methods: The CNKI, Wanfang, CBM, Pubmed, Embase, Ovid, Cochrane library databases were searched by computer. The randomized controlled trails with patient-controlled epidural analgesia or patient-controlled intravenous analgesia after spinal fusion published from May 1985 to July 2013 were selected. All of them were assessed by the standard of Cochrane systematic review. Data of postoperative VAS and the rate of side effects after using the analgesic drugs were extracted into an electrical sheet, which was synthesized by a Meta-analysis with RevMan 5.2 software. Re-sult: Eight randomized controlled trails involving 482 patients met the inclusion criteria. And the quality grade of 3 literatures was A, 5 literatures was B. The result of meta-analysis showed that: ①Visual analogue score(VAS). The postoperative first day′s VAS[WMD=-0.47, 95%CI(-0.74, -0.20)], second day′s VAS[WMD=-0.66, 95%CI(-1.14, -0.19)] showed that the patient-controlled epidural analgesia had a good analgesic effect compared with the patient-controlled intravenous analgesia, and both had statistic differences(P<0.05). No dif-ference in the postoperative third day′s VAS[WMD=-0.58, 95%CI(-1.38, 0.21)] was observed between the two methods, and no statistic difference(P>0.05); ②The side effects. The patient-controlled epidural analgesia had a higher incidence of skin itch[RR=1.53, 95%CI(1.08, 2.16)], paresthesia[RR=3.34, 95%CI(1.12, 9.98)] after surgery than the patient-controlled intravenous analgesia, and both had statistic differences(P<0.05). While two groups had no a significant deviation about nausea [RR=1.05, 95%CI (0.79, 1.40)], vomiting [RR=0.80, 95%CI (0.48, 1.31)], and no statistic difference(P>0.05). Conclusions: The patient-controlled epidural analgesia has better analgesic effects on the postoperative first and second day after spinal fusion, but obviously has a high-er incidence of skin itch and paresthesia than the patient-controlled intravenous analgesia.

Objective:To evaluate the characteristics of fusion using biomimetic n-HA/PA66 interbody cage with rhBMP-2 and discuss the feasibility of it.Methods:Thirty adult female goats underwent C_(3-4) discectomy and interverbral fusion performed with nHA/PA66 interbody cage without rhBMP-2(n=10).nHA/PA66 interbody cage with rhBMP-2(n=10),autogenous iliac crest bone graft(n=10).X ray was carried out at 4 and12 weeks after surgery to evaluate fusion quality.The goats were killed respectively on the 12th week.Nondestructive biomechanical testing for stiffness,un-decalcified histology were performed.Result:The goats in the n-HA/PA66 with rhBMP-2 group and the autogrft group all showed complete fusion at 12th week.there was no statisti- cally significant differience between the n-HA/PA66 with rhBMP-2 group and the autogrft group upon biomechanics,radiography and histomorphology.Conclusion:The interverbral fusion cage with n-HA/PA66 has good hiocompatibifity and osteoconductive ability and it may be good osteoionductive with rhBMP-2,so it was one ideal interbody fusion cage.
