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.

Myeloid-derived suppressor cells (MDSCs) are a group of heterogeneous and immature myeloid-derived cells,which accumulate largely in blood,lymphoid organs,spleen and tumor tissue and so on under the different pathogenic conditions such as infection,trauma,hematosepsis,especially tumor and so on.MDSCs can suppress tumor immune through many mechanisms.The number of MDSCs in periphery blood of patients is closely related with tumor stage,tumor burden,remote metastasis and prognosis.The major results are from laboratory mice.Because of the complexity of MDSCs in patients with tumor,there are many difficulties and debate on the research of them,and the researches of human MDSCs progress slowly.

Objective To investigate the serum procalcitonin (PCT),interleukin-6 (IL-6 ),hypersensitive C-reactive protein (hs-CRP)and white blood cells (WBC)joint detection in the value of early clinical diagnosis of neonatal sepsis.Methods Choose 84 cases with sepsis and 140 cases of mormal newborn in children between 2013.6.1~2013.8.31.Used the electro-chemical luminescence method and scattering turbidimetric method to detect levels of serum PCT,IL-6 and hs-CRP respec-tively,at the same time test whole blood white cells with XE-2100 instrument.Results There were significant difference be-tween serum levels of PCT,hs-CRP and IL-6 of the patients with sepsis and normal newborns (t=6.37~10.58,P<0.01) and no statistically significant difference for WBC (t=3.15,P>3.15).But joint detection of PCT,IL-6 and hs-CRP for neo-natal sepsis,the sensitivity was 98.81%,specificity was 90.24%,higher than any of them a detection sensitivity and special-ity degree.PCT in detection of neonatal sepsis,when 0.5 ng/ml≤PCT≤2 ng/ml,it was priority to with gram-positive bac-terium infection,and when PCT>2 ng/ml,was priority to with gram-negative bacteria infection,compared G+ bacteria infec-tion and G- bacteria infection,the difference was statistically significant (χ2=4.646.37~35.05,P<0.05).Conclusion PCT,hs-CRP and IL-6 detection has high sensitivity,strong specificity,they can provide evidence for early diagnosis and treatment of neonatal sepsis.

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.
