Objective To investigate the clinical value of peripheral serum cell-free DNA/neutrophil extracellular traps (cf-DNA/NETs) level in diagnosis and severity assessment of sepsis patients. Methods Forty patients with sepsis and 40 patients with non-infectious systemic inflammatory response syndrome (nf-SIRS) were enrolled in this study. The cf-DNA/NETs level in serum of all subjects were measured. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic ability of the cf-DNA/NETs, white blood cell count (WBC), procalcitonin (PCT) and interleukin-6 (IL-6). The sepsis patients were stratified into a survival group and a death group according to the prognosis. Sequential organ failure (SOFA) score were recorded in the sepsis patients, and the correlations between SOFA and cf-DNA/NETs, PCT, WBC, IL-6 were analyzed. Results Compared with the nf-SIRS group, cf-DNA/NETs and PCT levels were significantly higher in the sepsis group (both P<0.05). WBC and IL-6 showed no significant differences between the two groups (bothP>0.05). The area under the ROC curve (AUC) of cf-DNA/NETs was 0.884 for diagnosis of sepsis, and it was higher than the AUC of PCT (0.803). The cf-DNA/NETs showed better sensitivity (81.2% and 79.2%) and specificity (81.0% and 82.4%) than PCT. cf-DNA/NETs and PCT were significantly higher in the death group than those in the survival group. Bivariate collection analysis revealed positive correlations between SOFA score and the two biomarkers of cf-DNA/NETs and PCT (r1=0.573, r2=0.518; both P<0.01). Conclusions cf-DNA/NETs and PCT have certain value in early diagnosis of sepsis, and cf-DNA/NETs shows better diagnostic value in distinguishing sepsis from nf-SIRS than PCT. cf-DNA/NETs can be used as a routine monitoring index to help assess disease severity in sepsis.
Objective To evaluate the effect of postmastectomy radiotherapy(PMRT)on the rate of loco-regional recurrence and survival for breast cancer patients undergoing radical mastectomy with one to three positive lymph nodes. Methods The database of Pubmed, Embase, EBM Reviews-Cochrane Central Register of Controlled Trials, CBM, CNKI, VIP, and Chinese Cancer were searched. All randomized controlled trials about postmastectomy radiotherapy on breast cancer patients with 1-3 positive lymph nodes were considered for inclusion. Revman 5.3 was used in the meta analysis. Results Four trials enrolled 1 254 breast cancer women with 1-3 positive lymph nodes were included. The studies were high quality according to the evaluations of the quality criteria. After 10 to 20 years follow-up, the results showed that, 460 patients were analyzed in the result of loco-regional recurrence, the hazard ratio (HR) was 0.23, 95%CI (0.15, 0.37), the result showed statistical difference (P＜0.000 01), and the heterogeneity was existed (P=0.09,I2=59%). One thousand two hundred and fifty-four patients were analyzed in the result of overall survival, theHR was 0.82, 95%CI (0.71, 0.93), the result showed statistical difference (P=0.002 ), and there did not existed heterogeneity (P=0.65,I2=0%). Four hundred and sixty patients were analyzed in the result of metastasis-free survival, theHR was 0.71, 95%CI (0.56, 0.90), the result showed statistical difference (P=0.005), and there did not existed heterogeneity (P=0.63,I2=0%). Nine hundred and seventy-seven patients were analyzed in the result of disease free survival, theHR was 0.74, 95%CI (0.66, 0.85), the result showed statistical difference (P＜0.000 01), and there did not existed heterogeneity (P=0.49,I2=0%). Conclusion Through this systematic review, we consider that postmastectomy radiotherapy could reduce the loco-regional recurrence and increase the overall survival for long-term.
【摘要】 目的 分析手术治疗垂体瘤患者长期临床恢复以及生活质量改善情况。 方法 回顾性分析2007年12月-2008年9月手术治疗的103例垂体瘤患者术前以及术后长期随访资料，使用SF-36量表对术前、术后患者生活质量进行评估，分析手术治疗前后患者症状、激素水平恢复情况以及生活质量改善情况，并进一步分析肿瘤大小、侵袭程度对术后生活质量的影响。 结果 术后头痛症状消失52例，视力改善76例，其他症状具有不同程度改善；术后SF-36生活质量评估结果显示，患者除精神健康外的7个维度（生理机能、生理职能、躯体疼痛、一般健康状况、精力、社会功能、情感职能）均有明显改善（P＜0.05），不同肿瘤大小及侵袭程度的患者术后生活质量评分均无统计学意义（P＞0.05），垂体功能完全恢复者生活质量评分高于垂体功能低下者（P＜0.05）。 结论 显微手术治疗垂体瘤患者可明显改善患者的一般症状、提高患者的生活质量，单纯肿瘤的大小和侵袭程度对术后生活质量的影响程度较小，术后垂体功能的恢复程度明显影响患者的生活质量，垂体瘤术后患者的激素长期替代治疗尚需进一步加强。【Abstract】 Objective To analyze the long-term clinical recovery and quality of life (QoL) in patients with pituitary adenoma treated by microneurosurgery. Methods The clinical data of 103 patients undergoing microneurosurgery from December 2007 to September 2008 were retrospectively analyzed, health-related questionnairs (SF-36) were used to assess the QoL. The post-surgery recovery of symptoms, endocrine function, and QoL were compared with those of pre-surgery, then the correlation between tumor size, invasive behavior, and QoL were analyzed. Results Headache disappeared in 52 patients. Visual symptoms improved in 76 patients. Other symptoms were also improved. Seven concepts (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotioning) were improved after surgery (Plt;0.05). The eight health concepts of SF-36 showed no significant difference between patients with different tumor size and invasive behavior (Pgt;0.05). Differences were considered statistically significant between normal and abnormal pituitary function groups after surgery(Plt;0.05) in all concepts. Conclusion Microneurosurgical treatment can improve the general symptoms and the QoL. The tumor size and invasion have little influence on the QoL after surgery, but the improvement of hormone deficiency has influence on the QoL significantly. More attention should be given to the long-term hormone replacement therapy after the pituitary adenoma surgery.
In this study, the rescue effect of receptor activator for nuclear factor-κB ligand (RANKL) on zoledronate acid (ZOL) induced inhibition of osteoclastogenesis and gene expression of NF-κB p50 and c-Jun was investigated. Mice calvarial osteoblasts (OBs) were harvested and co-cultured with RAW264.7 cells and the cells were divided into 4 groups and received treatment with ZOL and RANKL, either single or combined. The formation of multi-nucleated osteoclast (OC) was examined and gene expression of NF-κB p50 and c-Jun was detected. Group B (ZOL) showed least multi-nucleated OC and resorption lacunae among the 4 groups (P<0.05 or P<0.01) and it was followed by group C (ZOL+RANKL). Group D (RANKL) showed highest OC and resorption lacunae while it was similar to Group A (control) (P>0.05). Gene expression of NF-κB p50 and c-Jun was the lowest in group B (P<0.05 or P<0.01) among the four groups and was significantly increased in group C when compared with group B (P<0.05). Group A and D showed highest gene expression and they were similar to each other (P>0.05). This study suggest that RANKL might partly rescue ZOL induced inhibition of osteoclastogenesis, and the effect of RANKL and ZOL on osteoclastogenesis may be mediated by NF-κB p50 and c-Jun.
ObjectiveTo investigate the effect of etomidate and propofol on inflammatory cytokines and cortisol for patients with lung adenocarcinoma. MethodSixty patients scheduled for lung cancer surgery under general anesthesia were studied. All patients were randomly divided into an etomidate total intravenous anesthesia group (group E, 30 patients, 16 males and 14 females at age of 58.0±5.0 years) and a propofol total intravenous anesthesia group (group P, 30 patients, 17 males and 13 females at age of 55.0±5.0 years), with 30 patients in each group. ResultsThe concentration of IL-6 in serum of patients in the two groups at time points T1, T2 and T3 was significantly higher than those at time point T0 (P < 0.01). The concentration of IL-10 and TNF-α in serum of patients at time points T1 and T2 was significantly higher than those at time point T0 (P < 0.01). And the difference of the concentration of TNF-α in serum of patients at time points T0 and T3 was not statistically significant (P > 0.05). The level of Cor of patients in the group E at time point T0 was slightly higher than those at time point T1, but lower than that at time points T2 and T3. There was no statistical difference in the concentration of IL-6 and TNF-α in serum of patients between the two groups. The level of IL-10 of patients in the group E at time points T2 and T3 was lower than those in the group P (P < 0.05), but no significant difference was observed at the other time points. The concentration of Cor in the patients in the group E at time point T1 was lower than that in the group P (P < 0.01), but no significant difference was observed either at the other time points. ConclusionThe effect of etomidate used for maintenance of general anesthesia on the inflammatory factors is essentially similar to that of propofol.
