Objective To investigate the effect of ambroxol pretreatment on the inflammatory response and lipid peroxidation during one-lung ventilation (OLV) .Methods Forty-five ASA I or II patients aged 37-64 yr weighing 53-65 kg undergoing thoracotomy under general anesthesia were randomly divided into 3 groups ( n = 15 each): group A two-lung ventilation (TLV); group B OLV and group C ambroxol 1 mg/kg + OLV. Anesthesia was induced with midazolam, fentanyl, propofol and atracurium and maintained with propofol infusion and intermittent iv boluses of fentanyl and atracurium. The patients were mechanically ventilated (VT8-10 ml/kg, RR 12 bpm during TLV, VT 6-7 ml/kg, RR 16 bpm during OLV, I: E 1:2, FiO2 100% ). In group C ambroxol 1 mg/kg in normal saline ( NS) 100 ml was infused at 25 min before OLV (infusion rate 4 ml/min) , while in group A and B equal volume of NS was infused instead of ambroxol. Blood samples were obtained from radial artery before induction of anesthesia and OLV (T0.1 ) and at 0.5, 1, 2 h of OLV (T2-4 ) and 1, 2 h of TLV (T5,6 ) and at 24 h after operation (T7) in group B and C for determination of serum SOD activity and TNF-α, IL-6 and IL-8 concentrations and WBC and neutrophil granulocyte counts. The same indexes were detected in group A at the corresponding time points.Results Serum SOD activity was significantly lower and serum TNF-α, IL-6 and IL-8 concentrations and WBC and neutrophil granulocyte counts were significantly higher in group B than in group A. Serum SOD activity was significantly higher and serum TNF-a, IL-6 and IL-8 concentrations and WBC and neutrophil granulocyte counts were significantly lower in group C than in group B. Conclusion Pretreatment with ambroxol 1 mg/kg can inhibit inflammatory response and lipid peroxidation during OLV.

Objective To investigate the in vivo transduction capability of fusion protein PEP-1-EGFP with mice.Methods Two prokaryotic expression plasmids pET15b-EGFP and pET15b-PEP-1-EGFP were constructed and transformed into E.coli BL21(DE3) to express EGFP and fusion protein PEP-1-EGFP,respectively.The expressed EGFP and PEP-1-EGFP were purified with Ni2+-resin affinity chromatography.Five hundred micrograms of EGFP and PEP-1-EGFP fusion protein were injected into mouse through caudal vein,respectively,the mice were euthanized and perfused with PBS 2 hours after administration.Then,the heart,brain,liver,spleen and kidney were removed and sectioned with a cryostat at 7 ?m for visualization with a inverted fluorescent microscope.ResultsThe brain,heart,liver,spleen and kidney injected with PEP-1-EGFP showed bright and homogenous green fluorescence whereas that with EGFP showed no green fluorescence at all.Conclusion The successful expression and purification of PEP-1-EGFP fusion protein and its efficient transduction into mice in vivo provide a basis for the research on transmembrane delivery of macromolecule drugs mediated by the cell-penetrating peptide,PEP-1.

OBJECTIVE To investigate the surgical management and its result of the cervical esophageal cancer.METHODS Forty six patients with cervical esophageal carcinoma who received surgical treatment in our hospital were included in this retrospective study.The removed hypopharynx and cervical esophagus were repaired with laryngotracheal flap in 5 cases,free myocutaneous flap in 4 patients and free jejunum in 2 patients.The inversion stripping esophagectomy without thoracotomy were performed in 35 patients.RESULTS During the early postoperative period,complications included recurrent laryngeal nerve paralysis in 2 cases,anastomotic fistula in 3 cases,anastomotic stenosis in 5 cases,Long-term postoperative gastro-esophageal reflux occurred in 19 cases.The 5-year survival rate was 28.7%. CONCLUSION The surgical treatment for cervical esophageal carcinoma should be decided by the location of the tumor,the extent of the cancer involved and lymph node metastasis.

Objective To explore the correlation between ITGA6 gene (rs12621278, G), MSMB gene (rs10993994, T), chromosome 8q24 (rs10086908, T) and prostate cancer (PCa) in Beijing residents, and to explore the correlation between genotype and phenotype in PCa patients. Methods PCa patient phenotypes were collected including clinical, genetic, dietary habits, hobbies and blood samples. ITGA6 gene (rs12621278, G), chromosome 8q24 (rs10086908, T) and MSMB gene (rs10993994, T) compared the allele distribution between 112 PCa and 91 healthy control age matched patients. The genotype and phenotype analysis was conducted in the 2 groups. Results Between the case and control groups, only rs10993994, T of MSMB gene (case 56.4%,control 46.2%) was significantly different (P=0.001; OR=1.97, 95%CI:1.28-3.04). The rs10086908, T of 8q24 (case 83.5%, control 79.2%) and rs12621278, G of ITGA6 gene (case 27.2%, control 27.0%) were not significantly associated with PCa in the study sample (P>0.05). Quantitative trait analysis showed that the disease duration of ITGA6 risk genotypes (G/G,1.40±0.55 years) in PCa patients was significantly shorter (P=0.003) than the other genotype carriers (A/G, 4.38±3.10 years; A/A, 2.37±1.84 years). Conclusion The genetic variation in MSMB is possibly associated with PCa susceptibility, suggesting that MSMB genes might be associated with PCa in a Chinese population.

Objective: To discuss the clinical pathology characteristics, strategies of diagnosis and therapy, and related prognosis factors of pancreatic neuroendocrine tumors(pNET). Methods: Clinical data of 103 pNET cases in Department of Pancreatic Surgery, Changhai Hospital of Second Military Medical University were collected from January 2006 to December 2015. There were 44 males and 59 females, aged from 21 to 77 years with mean age of 48 years.Of the 103 patients, there were functional type in 21 cases and no functional type in 82 cases. Related factors on diagnosis and treatment were summarized. Moreover, univariate survival analysis was performed by Kaplan-Meier method, and COX proportional hazards model was used for multivariate survival analysis. Results: The detection rates of the B-ultrasound, CT, MRI were 60.2%, 84.6% and 91.3%, respectively, and there were 44 cases located in pancreatic head, 18 cases in pancreatic neck and 41 cases in pancreatic body and tail.G1 was the most common pathological grade, and the positive rates of Chromogranin A, Syn, neuron-specific enolase and CAM5.2 were 97.1%, 97.1%, 91.3% and 93.2%, respectively. The results of statistical analysis showed that tumor grade(χ²=26.077, P<0.05), Ki-67 index(χ²=25.427, P<0.05), ENETS stage(χ²=5.915, P<0.05), AJCC stage(χ²=8.411, P<0.05), lymph node metastasis(χ²=4.770, P<0.05) and distant metastasis(χ²=8.411, P<0.05) were associated with the prognosis of pNET, and the tumor grade was an independent risk factor of the pNET′ overall prognositic factors (HR=3.085, P<0.01). Conclusions The pNET can be located in any part of pancreas, and the combination of laboratory and various imaging examinations can help make early diagnosis. In addition, tumor grade, Ki-67 index, ENETS stage, AJCC stage, lymph node metastasis and distant metastasis were closely related to the prognosis of pNET, and the higher the tumor grade, the worse the prognosis.
