Objective To investigate the clinical effectiveness of fast track surgery ( FTS) nursing during laparoscopic cone-shaped resection of renal tumor. Methods Forty patients who was planned to accept laparoscopic cone-shaped renal tumor resection was divided into either FTS group ( n=20 ) or control group ( n=20 ) according to odd-even number of their admission IDs. The control group was given routine perioperative nursing procedure, and the FTS group was given FTS nursing. Results The operation time, intraoperative blood loss and incidence of complications had no statistical significance between the two groups (P>0. 05). As compared to the control group, patients in the FTS group experienced a shorter anal exhaust time [(30. 3 ± 11. 7) h vs. (43. 0 ± 15. 5) h, t= -2. 924, P=0. 006], shorter post-operative fasting time [(26. 6 ± 12. 1) h vs. (56. 1 ± 18. 1) h, t= -6. 059, P=0. 000], earlier ambulation [(33. 6 ± 16. 8) h vs. (66. 9 ± 28. 6) h, t= -4. 490, P=0. 000], shorter urethral catheterization [(40. 2 ± 18. 5) h vs. (83. 4 ± 39. 6) h, t= -4. 420, P=0. 000], shorter drainage time [(50. 3 ± 22. 5) h vs. (102. 9 ± 46. 0) h, t= -4. 594, P=0. 000], and shorter length of hospitalization [(5. 5 ± 1. 5) d vs. (9. 0 ± 2. 1) d, t= -5. 911, P=0. 000]. Conclusions FTS nursing procedure can reduce the rate of post-operative complications and shorten hospitalization stay. It can not only guarantee the efficacy of surgical treatment but also help the patient to achieve the goal of fast rehabilitation, being worthy of extensive application.

Objective:Imatinib is extensively used as a first-line therapeutic agent for patients with chronic myeloid leukemia (CML) at the chronic phase (CP). Although CML patients undergoing imatinib treatment are enrolled mainly in the Glivec International Patient Assistance Program (GIPAP) in China since 2003, limited data have been reported on the long-term outcome of these patients. This study aims to compare the treatment response and prognosis of CML-CP patients who received different treatments from January 2003 to December 2013 in the First Affiliated Hospital of Nanchang University. Methods:A total of 295 patients were enrolled, includ-ing 185, 30, 50, and 30 patients for imatinib, interferon-alpha (IFN-α) plus Ara-C, hydroxycarbamide (HU), or allogeneic hematopoietic stem cell transplantation (Allo-HSCT) treatments, respectively. Results:Patients in imatinib and Allo-HSCT groups achieved excellent complete hematologic remission (CHR) (i.e., 96.7%vs. 96.7%), complete cytogenetic response (CCyR) (i.e., 89.7%vs. 93.3%), and com-plete molecular remission (CMoR) (i.e., 49.7%vs. 83.3%, P=0.001). However, significantly low rates of CHR, CCyR, McyR, and CMoR were observed in IFN-αand HU groups. Moreover, patients from imatinib group showed longer overall survival (OS) time than patients from other groups (P<0.001), even patients in Allo-HSCT group (10-year OS, 89.0%vs. 67.0%, P<0.001) because of high risk of Allo-HSCT-related complication. Multivariate analysis showed that receiving imatinib treatment (HR=5.267, 95%CI:1.054-1.940, P=0.022) and achieving CCyR (HR=9.541, 95%CI:1.692-10.513, P=0.002) were independent predictors for OS. Conclusion:Imatinib treatment may be an optimal first-line choice for Chinese patients with CML-CP who have not received any previous treatments.

Severe trauma can result in severe respiratory and circulatory failure with a high mortality rate，which is quite difficult for clinical treatment. In recent years，the application of extracorporeal membrane oxygenation（ECMO）to circulatory and/or respiratory failure caused by severe trauma has received more and more attention. Systemic anticoagulation is often considered as a relative contraindication to ECMO therapy in patients with severe trauma who are at higher risk of bleeding. However，recent studies have shown that venovenous（VV）-ECMO is safe and feasible for treatment of severe acute respiratory failure after trauma，and venoarterial（VA）-ECMO is of great value for treatment of cardiogenic shock and traumatic cardiac arrest. The issues such as the timing of application，anticoagulation strategies，impact on survival and risk-benefit evaluation related to ECMO application to trauma care need to be investigated further. In this study，the authors summarize advances in application of ECMO，prevention and management of related complications in patients with severe trauma，so as to provide a reference for improving the application level of ECMO.

To explore the activity of the pmel core promoter of Bashang long-tail chickens, we constructed dual-luciferase expression vectors and transiently transfected into DF1 cells with Lipofectamine 2000. We measured the luciferase activity with the dual-luciferase detection kit. The 1 268 bp fragment in 5-flanking region of the pmel gene in Bashang long-tail chickens was cloned. The region from -1 200 bp to +68 bp included 2 CpG islands and multiple transcription factor binding sites. We constructed 9 expression vectors with different promoter regions and a mutant vector of the core promoter region of the pmel gene of Bashang long-tail chickens. The core promoter region from -840 bp to +68 bp was identified in the pmel gene. The region from -590 to -525 bp negatively regulated the pmel gene during the transcription process. The -840--590 bp and -525--266 bp regions were positive regulatory regions. The polymorphic sites (-456, -435, -410, -374 and -341) had a significant effect on the promoter activity of the pmel gene.

The aim of this study was to clone the chicken zp1 gene encoding zona pellucida 1 (Zp1) and investigate its tissues expression profile and its effect on osteoblast mineralization. The expression level of zp1 was quantified in various tissues of laying hens and in the tibia of the pre- and post-sexual maturity by RT-qPCR. Zp1 overexpressed vector was transfected into chicken calvarial osteoblasts which were induced differentiation for 8 days, and the extracellular mineral and the expression of mineralization-related genes were detected. The full-length chicken zp1 gene is 3 045 bp, encoding 958 amino acids residuals, and has two N-glycosylation sites. The highest expression level of the zp1 gene was found in the liver, followed by the tibia and yolk membrane, while no expression was detected in the heart and eggshell gland. Compared with the pre-sexual maturity hens, the concentration of estrogen (E2) in plasma, the content of glycosaminoglycan (GAG) and the expression level of the zp1 gene in the tibia with post-sexual maturity were higher. The extracellular matrix and the level of osteoblast mineralization-related genes showed a significantly upregulated expression in chicken calvarial osteoblasts with Zp1 overexpressed and addition of estrogen. The expression of the zp1 gene is tissue-specific and positively regulated osteoblast mineralization under the action of estrogen, laying the foundation for elucidating the functional properties of Zp1 in chicken bones during the egg production period.
