Objective To discuss the protective effect of doxofylline on radical surgery for esophageal cancer.Methods Under elective general anesthesia, 60 cases, 35 males and 25 females, aged 45-70 years, BMI 20-30 kg/m2, ASA physical status Ⅰ or Ⅱ, FEV1%>50%, underwent radical surgery for esophageal cancer at middle and distal parts.Random number table was employed to divide these patients into two groups: doxofylline group (group D) and control group (group C) with 30 cases in each.After a routing intravenous induction in the two groups, mechanical ventilation was conducted after bronchial intubation with double channel catheter on the right side.The intravenous injection of doxofylline 4 mg/kg in group D was administrated 30 min after bronchial intubation with double channel catheter.Equal normal saline was instilled to the patients in group C.Blood samples were taken from radial artery to detect the levels of TNF-α, IL-6, IL-10, MDA and SOD at four time points: 10 min (T0) before the one-lung ventilation, 60 min after OLV (T1), after two-lung ventilation (T2) and the end of the operation (T3).Meanwhile, the blood and breath at these time points were tested.The occurrence of OLV, blood loss volumes, fluid input quantities, urine volumes, postoperative hyoxemia and pulmonary inflammation were observed.Results Compared with T0, the activity of SOD in serum and PaO2 in the two groups at T1-T3 decreased (P＜0.05).The concentrations of TNF-α, IL-6, IL-10 and MDA increased significantly (P＜0.05).Compared with group C, the activity of SOD activities and PaO2 in group D at T1-T3 increased while concentrations of TNF-α, IL-6, IL-10 and MDA decreased significantly (P＜0.05).The occurrence rates of postoperative hyoxemia and pulmonary inflammation in group D were obviously lower than those in group C (P＜0.05).Conclusion Doxofylline can suppress patients' inflammatory response and oxidative stress response after OLV and reduce the incidence rates of postoperative hyoxemia and pulmonary inflammation as well as alleviate lung injury triggered by radical surgery for esophageal cancer.

Objective To compare the clinical effect of hepatic artery perfusion of antibiotics with that of intravenous administration of antibiotics in treating pyogenic liver abscess which is unsuitable for puncture drainage management. Methods Between October 2010 and October 2013, a total of 32 cases with bacterial liver abscesses which were unsuitable for puncture drainage management were encountered at the Third Affiliated Hospital of Wenzhou Medical University. The patients were divided into group A (n = 15) and group B (n = 17). Hepatic arterial perfusion of antibiotics was carried out in the patients of group A, while intravenous administration of antibiotics was employed in the patients of group B. Percutaneous puncture drainage was adopted in the patients when their imaging examination showed liquefaction within the lesion. Results The hospitalization time, recovery time of body temperature, hemogram recovery time and liquefaction extent of the lesion in group A were much better than those in group B , and the differences were statistically significant (P < 0.05). Conclusion Hepatic arterial perfusion of antibiotics is an important and effective treatment for bacterial liver abscesses.

Objective To evaluate the clinical efficacy and safety of transcatheter arterial chemoembolization (TACE) with oxaliplatin (OXA), fluorouracil (5-Fu) and pirarubicin (THP) scheme in treating primary liver cancer. Methods A total of 65 patients with primary liver cancer were treated with TACE using infusion of OXA/5-Fu/THP scheme (TACE group). Other 21 patients with primary liver cancer, who were encountered at the Department of Interventional Radiology of authors’ hospital during the same period as the patients of TACE group, received simple transarterial embolization (TAE group). The therapeutic effect, the occurrence of adverse reactions, the progression-free survival time (PFS) and overall survival time (OS) of the two groups were comprehensively evaluated. The results were compared between the two groups. Results In the TACE group, the objective response rate (ORR) and disease control rate (DCR) were 55.4%and 81.5%respectively, and the median PFS and median OS were 11.5 months and 18.5 months respectively. Single factor analysis indicated that patients, who had liver function of Child-Pugh A and received more times or treatment, and who had small-sized tumor and no portal vein tumor thrombus or metastasis, usually had a better prognosis, and the differences were statistically significant (P<0.05). The prognosis of the patients with Barcelona staging (BCLC) B was better than that of the patients with Barcelona staging C, and the difference was statistically significant (P=0.000). Cox multivariate analysis revealed that the portal vein tumor thrombus and tumor metastasis were independent risk factors for the prognosis of the patients. Compared with the TAE group, TACE with OXA/5-Fu/THP scheme could effectively improve the mean progression-free survival time. Conclusion For the treatment of primary liver cancer, TACE with infusion of OXA/5-Fu/THP is clinically effective with fewer adverse reactions.

BACKGROUNDChronic exposure to n-hexane can lead to peripheral neuropathy that no effective treatment regimen could be applied presently. This study investigated whether myelin protein zero (P0) protein and its antibody could be used to distinguish n-hexane intoxication and protect workers from peripheral neuropathy.

METHODSWe compared P0 protein and its antibody among three levels of n-hexane-exposed groups, which included 18 patients with n-hexane-induced peripheral neuropathy as case group, 120 n-hexane-exposed workers as n-hexaneexposed control group, and 147 non-hexane-exposed participants used as control group. ELISA method was applied to detect P0 protein and its antibody.

RESULTSP0 protein in serum was significantly higher in the case group and n-hexane-exposed control group in comparison with the control group (P < 0.01). Compared with the n-hexane-exposed control group, the case group also had significant increase of P0 protein (P < 0.01). After 6 months therapy, P0 protein was observed to decrease significantly in the case group (P < 0.01). The P0 antibody in serum was significantly higher in the n-hexane-exposed control group than in the control group (P < 0.01), but not significantly different between cases and controls.

CONCLUSIONSP0 antibodies in serum may be a short-term effect biomarker for n-hexane exposure. P0 protein in serum may be an early effective biomarker for peripheral nerve neuropathy and its biological limit value needs investigation in the future study.
